Abstract: 2164-24a ABSTRACT     Apparatus for comminuting bulky pieces of waste material or the like has two parallel shafts which are driven at the same speed but in opposite directions and carry several sets of cooperating knives.  The knives of each set have closely adjacent and faces which are bounded by sharp cutting edges surrounding relatively narrow raised marginal zones.  A portion of the marginal zone of one knife of each set always overlies a portion of the marginal zone of the other knife.  When the marginal zones undergo pronounced wear, the knives of the respective set are shifted axially of the respective shafts to move the marginal zones nearer to each other.  The neighboring knives on the same shaft are angularly offset with respect to each other and are coupled to each other by pins which extend into sockets provided in the end faces of the knives.  The knives are formed with peripheral lobes which alternate with recesses whereby a recess of one knife of each set of knives is adjacent to a lobe of the other knife of the same set, or vice versa, in each angular position of the knives. The raised marginal zones are obtained by machining shallow endless grooves into the end faces of the knives.  The outer boundaries of the grooves are immediately adjacent to the respective raised marginal zones, and the inner boundaries of the grooves are spaced apart from the central bores of the respective knives and surround the sockets in the end faces of the corresponding knives.

Abstract: A B S T R A C T           A method of and an apparatus for bending an elongate metal element, such as a pipe, are disclosed.  An arm is secured to each end of the element portion to be bent and with a pulling device such as a chain, hydraulic cylinder or the like connecting the arms.  The pulling device is operated to exert a bending moment on the element that is insufficient to cause its permanent deformation.  A local bending stimulation is then applied to and moved along the pipe to cause the required bending.  The stimulator may be a mechanical roll or press bender or it may simply be a heater.  The arrangement may be such that a large compressive force is applied to the workpiece to prevent wall thinning on the outside of the bend.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to the storage of information upon a videodisc.  Prior art attempts at storing video information on a disc have involved processing procedures producing recorded intelligence information on a disc directly from a corresponding intelligence signal in amplitude varying with time format.  The present invention provides an improved apparatus and method for reliably storing information on a videodisc in the form of a carrier frequency having frequency changes with time varying from the carrier frequency.  In accordance with the invention, a video-disc having a light responsive coating covering the disc substrate is provided, and a light source produces a light beam of sufficient intensity to interact with the responsive coating of the videodisc as the disc rotates.  An optical system defines an optical path between the light source and the responsive coating on the disc for focusing the light beam on the coating.  A light intensity modulator, responsive to the informa-tion signal, is positioned in the optical path for intensity modulating the light beam.  The beam passing through the intensity modulator and optically focused on the responsive coating on the disc forms an informa-tion track of indicia representing the frequency modu-lated information signal.  The information signal and altered coating of the disc contain intelligence in-formation in the form of a carrier frequency varying in frequency as a function of time.
