Title: Magazine for piles of register-punched sheets
Inventor: KRATZSCH ACHIM
IPC: B65H1/06
Filed: 1983-12-27
Abstract: The invention relates to a magazine for piles of preferably register-punched sheets, with separation of the sheets from the bottom of the pile, for application in collating machines used in the manufacture of annual calendars, commercial documentation and the like, preferably as an integral part of an adhesive binding system. The aim of the invention is to prevent registering tears from occurring as register-punched sheets are separated, in order to permit manufacture of the above products on adhesive binding systems. The folded sheets adhering to one another at the punched edges are to be separated before the separating process, avoiding damage. This is carried out in a magazine, which is provided with an inclined stop which extends at an acute angle to the stacking table. By the arrangement of a pile support according to the invention, the pile is raised on one side and a concave position is therefore achieved for the bottom sheet, thus facilitating the drawing off of sheets. <IMAGE> Drawing off the exposed sheet.

Patent DE-3504591-A1 (DE)
Title: Pushing conveyor
Inventor: GITTELBAUER JOACHIM
IPC: B65G25/10
Filed: 1985-02-11
Abstract: In order to be able to convey granular, powdered or pasty materials even over relatively long distances (e.g. over 300 m) in pushing conveyors, very high starting resistances must in each case be overcome by the driving mechanism when the conveyors are started and the materials are conveyed. According to the invention, however, the starting resistance when the materials are conveyed is very substantially reduced in that a plurality of buckets (3) are in each case combined into groups (I, II, III), and the buckets (A, B, C; A', B', C'; A'', B'', C'') within the groups are pivotably fastened in joints (24) to a pushing rod (2) at intervals which vary within a group but which are the same in all the groups, and in that the groups are arranged at identical distances from one another. The material to be conveyed is fed into the channel (1) within a group of buckets at different distances from the buckets (3) in each case, so that heaps (7) of material to be conveyed are formed which are successively taken hold of and displaced by the buckets (3) during starting. During conveying, each heap of material to be conveyed is displaced to a position which was previously occupied by another heap of material to be conveyed. <IMAGE>
Patent DE-3512324-A1 (DE)
Title: Device for reducing the tyre wear on the undercarriages of aircraft
Inventor: PARLEVLIET THEODOR
IPC: B64C25/40
Filed: 1985-04-03
Abstract: The tyres on the undercarriages of aircraft are subjected to a high level of wear in the case of the previous designs, since, when they initially touch the ground, the wheels are accelerated in a very short time from an angular speed of zero to that corresponding to the landing speed. In order to prevent the tyre wear which occurs as a result of the high circumferential forces between the tyres and the runway during the rotational acceleration phase of the wheels, said wheels are set in rotation before the landing so that the rotation acceleration required on touchdown is ideally equal to zero. The drive for the rotational movement of the wheels in the air can be provided by air nozzles which are permanently connected to the undercarriage and direct an air flow, which is produced by the relative speed between the aircraft and the surrounding air, onto a blade system which is fitted to the wheel rims.
