Title: Delivery conveyor
Inventor: GEYER HERBERT
IPC: B65G15/14
Filed: 1986-10-01
Abstract: Delivery conveyor for bulk-material packaging machines, with a lower and an upper band and with a device for adapting the spacing of the two bands to different pack heights. The aim of the invention is to reduce the actuating forces during the actuation of delivery conveyors and to lower the machine-building outlay. The object is to adjust the lower and upper band and the package carrier rails jointly and automatically, the working strands remaining parallel to one another. The object is achieved in that the lower and upper band are connected to one another via a parallel-guide gear, and in that a worm gear with two actuating levers is arranged between the package carrier rail and lower band, one lever being articulated on the lower band and the second actuating lever being articulated on the package carrier rail. The parallel-guide gear is designed as a pendulum linkage, the pendulum having two arms of equal length, and the distance between the centre of rotation of the lower band and the point of articulation of the linkage on the bearing plate of the lower band being equal to the distance between the centre of rotation of the upper band and the point of articulation of the linkage on the bearing plate of the upper band. <IMAGE>

Title: Method for environment-friendly removal of cattle and/or pig liquid manure
Inventor: NEMETZ HERBERT
IPC: C05F3/00
Filed: 1988-02-25
Abstract: The invention relates to a method for environment-friendly removal of cattle and/or pig liquid manure in a tunnel reactor (1), a carbon carrier (2.2), such as e.g. sawdust, being added to the manure during the starting of the reactor. The material (2) is in general charged in daily portions (2.3) and guided through the tunnel reactor by a pressing shield (3) which is advanced and in each case returned into its starting position. During the starting stage, the liquid manure (2.1) is mixed with a carbon carrier of good absorbency and over a period of one to two days is guided through the drip region (5) and during this the surplus liquid which is not taken up is separated off via a perforated floor (4). The material thus prepared then enters the composting region (6) and is intensively ventilated here over two weeks. After the exit of the material (2) as raw compost, it is arranged on a secondary rotting surface by means of mobile transport devices, layered and, after a storage time of approximately two weeks, returned as return material to the tunnel reactor (1), forming a replacement for the carbon carrier (2.2) and during this is irrigated with new liquid manure (2.1). This process is repeated over and over again during a period of approximately six weeks. The surplus material which is accumulated during this period is stored separately until it is subsequently used. <IMAGE>

Title: Connecting link for vehicle chains
Inventor: PILZ VOLKER DR ING
IPC: F16G15/04
Filed: 1988-03-04
Abstract: The connecting link for tyre anti-skid chains has a ring part with legs which project outwards, are spaced apart from one another and on which a locking piece is fixed. The locking piece projects a relatively long distance into the region of the ring opening so that the hooked-in chain links do not have a sufficient clearance of motion. In order to ensure a sufficient clearance of motion for the chain links and additional securing for the locking piece, at least one of the legs has a stop which is effective in the longitudinal direction of the leg and is intended for the locking piece against which the legs, under pretension, bear. Between the legs is at least one securing part. The connecting link is suitable for chain nets and extreme conditions of use since the locking piece is held securely on the legs and by virtue of the stop unintentional slipping of the locking piece is prevented. Due to the arrangement of the locking piece on the legs the link opening is open and, as a result, the hooked-in chain links have a large clearance of motion.

Title: Aero-/aerothermodynamic free-flight tests in the hypersound range with the aid of the transfer orbit
Inventor: FUCHS MANFRED DIPL ING
IPC: G01M99/00
Filed: 1988-03-05
Abstract: In order to be able to test missiles economically in the hypersound range at high altitudes, it is here proposed to start these missiles together with a satellite payload. The 24 hour transfer orbit provided for the satellite is used for the missile. The missile separated from the satellite uses the apogee height as energy excess in order to survive several transits in the atmosphere at the perigee (180 : 80 km). The aero-/aerothermodynamic measurements in the hypersound range are carried out during re-entry at the various altitudes. When the excess energy (about  DELTA V = 2700 m/s) is used up, the missile returns to earth.
