bond, in finance, usually a formal certificate of indebtedness issued in writing by governments or business corporations in return for loans. It bears interest and promises to pay a certain sum of money to the holder after a definite period, usually 10 to 20 years. Security is usually pledged against a bond; unsecured bonds are regarded as a long-term obligation on the capital of the issuing body. Some bonds are convertible upon maturity into the stock of the issuing company. One method used to retire bonds is the sinking fund; in such a case the issuing body buys back some of its bonds each year and holds them itself, applying the interest to the fund. The entire bond issue, most of which the firm has already acquired, is then retired on maturity. In the case of serial bonds, part of the issue is called in and paid for in full each year. Bonds were sold by the U.S. government to finance both World Wars and are still an important money-raising device. Government bonds are backed by the full faith and credit of the government issuing them, including its taxing power, and sometimes also by specifically designated security. Bonds are usually bought by those wishing conservative investment. A junk bond has a risky credit rating because it is issued by companies without an established earnings history or with a questionable credit history. Junk bonds have increasingly been used to help finance the purchase of companies, especially in leveraged buyouts.

An arrangement of masonry units to provide strength, stability and in some cases beauty by setting a pattern of overlapping units on one another to increase the strength and to enhance the appearance, or by connecting them with metal ties.

basketweave bond

A checkerboard pattern of bricks, laid either horizontally and vertically, or on the diagonal.

bull header bond

A brick header unit which is laid on edge so that the end of the masonry unit is exposed vertically.

bull stretcher bond

Any stretcher which is laid on edge exposing its broad face horizontally.

chain bond

A masonry wall bond formed by horizontal metal bars or pieces of lumber built into a wall.

common bond

A bond in which every fifth or sixth course consists of headers, the other courses by stretchers


A horizontal row containing brick headers in a masonry structure.

cross bond

A brick bond with courses of Flemish bond with alternating courses of stretchers and with the joints of every other row of stretchers centered on a vertical line of headers.

diagonal bond

A type of raking bond in masonry walls, consisting of a header course with the bricks laid at a diagonal in the face of the wall.

dogtooth course

A stringcourse of bricks laid diagonally so that one corner projects beyond the face of the wall.

Dutch bond

Same as English cross bond or Flemish bond.

English bond

Brickwork that has alternate courses of headers and stretchers, forming a strong bond which is easy to lay.

Flemish bond

In brickwork, a bond in which each course consists of headers and stretchers laid alternately, each header is centered with respect to the stretcher above and the stretcher below it.

Flemish diagonal bond

A bond in which a course of alternate headers and stretchers is followed by a course of stretchers, resulting in a diagonal pattern.

header bond

A pattern of brickwork consisting entirely of headers; usually displaced by one-half the width of one header in the course above and below.

herringbone bond

A brick wall bond with concealed diagonal headers laid at right angles to each other in a herringbone pattern.

raking bond

A method of bricklaying in which the bricks are laid at an angle in the face of the wall; either diagonal bond or herringbone bond pattern.

running bond

Same as stretcher bond.

skintled bond

Brickwork laid so as to form a wall with an irregular face, produced by the rough appearance of the skintled joints.

soldier bond

A brick course laid vertically with the longer narrow face exposed.

stack bond

In brickwork, a patterned bond where the facing brick is laid with all vertical joints aligned; in stone veneer masonry, a pattern in which single units are set with continuous vertical and horizontal joints.

timber bond

Horizontal timbers once used as a bond for a brick wall.

a security that conveys to its bearer the right to income computed at a fixed percentage rate. The entity issuing the bond assumes the obligation to redeem it over a prescribed period of time by paying income to the bearer of the bond, either through winnings allocated in special lottery drawings or through the reimbursement of coupons.

In the USSR, the right to issue bonds for domestic borrowing belongs solely to the state. The bond embodies a special form of obligation under civil law, one by which the state is the debtor and the citizen placing money at the disposal of the state is the creditor. The bonds currently in circulation are 3 percent lottery bonds, issued for a 20-year term in 1966. Income is paid to bondholders in the form of lottery winnings. The bonds are freely bought and sold by savings banks; their selling prices are set by the Ministry of Finance of the USSR, and they are purchased at face value. Various transactions relating to trusts, gifts, and bequests may also be carried out using bonds. Bonds may be presented for redemption throughout the period in which they are in force and during an additional grace period of 18 months. On expiration of this period, bonds that have not been presented for redemption lose their force. Bonds and cash winnings derived from them are tax exempt.

In the capitalist countries, bonds are issued both by joint-stock companies and by the state. As a form of paper security, bonds circulate freely through the capital market at a quoted price that is determined by their yield, by the general interest rate, and by overall factors of supply and demand. The state uses the capital mobilized through the sale of its bonds primarily to cover budget deficits that result from enormous nonproductive expenditures, above all expenditures on the arms race. The debt formed from the sale of bonds and the payment of interest is repaid primarily through taxes that are collected for the most part from the working people. The profits of joint-stock companies provide the source of the interest paid on their bonds.

The FTIR reflection spectra of chalcogenide [Ge.sub.x][Sb.sub.40-x][Se.sub.60] films studied in the terahertz spectral range at oblique (75[degrees]) incidence radiation showed characteristic bands related to Sb-Se and Ge-Se chemical bonds vibration in Ge[Se.sub.3] pyramidal and Ge[Se.sub.4] tetrahedral units, respectively.
A heater coil surrounded the vessel, as heat breaks the weak chemical bonds and releases the stored hydrogen.
It should be noted that the chemical bonds exist below a A/I ratio of 1.0 when the completion of reaction is assumed.
When samples were baked at temperatures ranging from 175[degrees]C to 275[degrees]C, however, chemical bonds formed between clay particles and hardened the soil to an adobelike consistency, rendering its surface extremely resistant to erosion.
In the case of heat-reactive phenolic resins, a certain percentage of direct chemical bonds (free methylol groups) can be assumed.
The key: Break and remake the chemical bonds that give your locks their "shape."
Detailed drawings illustrate the structure of atoms, chemical bonds, magnetism, kinetic theory, and many other fundamentals.
At slow rates, fracture occurs by weak, viscous flow without breaking chemical bonds. A few crosslinks give branched molecules, which are more difficult to disentangle and hence strength increases.
Chemical reactions don't happen "just like that." It takes a jolt of energy to get things started (that is, to break the original chemical bonds).
Potential topics include how electric charge is distributed within individual electrons and the ways in which chemical bonds form and break.
The chain segments are essentially frozen in place and the only motion that can take place is due to bending and stretching of chemical bonds. The polymer therefore is highly elastic in this region.
