an excavating machine for loosening layers of frozen soil, rock (usually of medium strength), and artificial surfaces in layers using the tractive force of a prime mover. Rippers are used in construction together with other excavating machines to prepare foundation pits, canals, and trenches; they are also used for stripping work in open-pit mines.

Rippers are equipped with a trailer or mounted tined device with elements for attachment to the prime mover and a hydraulic drive. A distinction is made between three-armed, four-armed, and parallelogram mounted devices. Rippers may have remote adjustment for the angle, operating width, and depth of ripping. The working member of the ripper is a tooth with a replaceable tip and a wear-resistant protective covering. Modern rippers usually have a hydraulic drive to raise and lower the teeth, change the ripping angle of the tip of the tooth, control the mechanism that positions the arms, and change the spacing of the teeth. Some rippers have shock absorbers to reduce the transfer of peak dynamic loads to the prime mover and attachments for working with push tractors.

To this end, Ripper, who, raised as a Baha'i, assures the viewer that whereas when he was a child he used to "create his own dreams" (which I find hard to believe), now his "subconscious is running the show," and his dreams, he tells us in a particularly sanctimonious drone that is irritating at the beginning of the film and grows steadily more irritating as it progresses, "are getting darker and darker." Ripper has this annoying tendency to make you feel that fear and grief are his own special province, that he's a virtuoso of suffering, that he is somehow more alert to suffering than the rest of us are.
(A total of eighty murders occurred in the whole of London in 1887, almost exactly the same, in per capita terms, as the number, 142, of murders in London in 1997.) It was the rarity of homicides in the East End, let alone grotesque multiple killings, which made the Ripper so infamous.
