Title: Document shredding machines
IPC: B02C18/00
Filed: 1979-10-20
Abstract: Document shredding machine of the type comprising a cutter assembly comprises two rows of cutting discs mounted for rotation in opposite directions about parallel axes, the discs (6) Fig. 2 of one row being arranged to enter gaps between adjacent discs (8) of the other row with little or no clearance. Stripper members (10, 12) are mounted on the shafts (2, 4) for limited movement between two positions, the stripper members adopting one of said positions when the shafts are driven in an operative direction, and adopt the other of said positions when the shafts are driven in a reverse direction. Thus, when the shafts are driven in said operative direction, the stripper members are operative to remove shredded material from between adjacent cutter discs during normal operation of the machine. However, by reversing the direction of rotation of the shafts (2, 4) the stripper members will move in a manner to effect dislodgement of any accumulation of shredded material built up on the machine. <IMAGE>

Title: Sighting and target tracking instruction apparatus
IPC: F41G3/26
Filed: 1980-01-16
Abstract: An apparatus for instructing marksmen in the art of sighting a weapon or tracking a target includes a sighting instrument 7 mounted on a weapon 6, through which the marksman can observe a target, and a calculator which, when training a marksman in the art of sighting the weapon, calculates sighting points from data concerning the distance to the target and its moving path. When target tracking in conjunction with the simulated firing of a controllable projectile, the calculator calculates the position of the projectile in space from data relating to the distance to the target and the control signals generated for guiding the projectile. The apparatus also includes a cathode ray tube 8 which receives from the calculator signals representing sighting points or the position of the projectile, and reproduces in the sighting instrument 7 the position of relevant sighting locations when the marksman carries out a firing movement or when the simulated projectile passes the target plane, thus enabling the marksman to compare the actual result with the theoretical result calculated by the calculator. <IMAGE>

Title: Article sorting apparatus
Inventor: O'FLANAGAN MICHAEL
IPC: B07C5/12
Filed: 1981-09-09
Abstract: Article sorting apparatus has a conveyor 1 by which a linear array of upstanding bottles are carried through a sorter 2. The sorter 2 separates short bottles, broken topped or fallen bottles on the conveyor from those of a standard height by use of a spring loaded lever 10 which applies transverse pressure to each bottle to direct a non-standard bottle through a window 5 over an upstanding flange 6. Standard height bottles are restrained from transverse displacement by engagement of their upper neck portions within an inverted channel 8 and by abutment of their bases against the flange 6. A second spring loaded lever 13 engages each bottle upstream of the lever 10 to temporarily restrain the bottles and provide a spacing between the bottles prior to them coming into contact with the lever 10. The lever 13 is at a low level as compared with the lever 10 and additionally serves to apply transverse pressure for removal through the window 5 of bottles which have fallen over on to the conveyor. <IMAGE>
