Title: Plastics flywheel, esp. for energy storage in vehicles - has reinforcing fibres in rim stiffer than those in spokes
Inventor: NIEDERSTADT GUENTER DR ING
IPC: F16F15/305
Filed: 1980-10-31
Abstract: Flywheel, esp. as an energy store in a vehicle, has a peripheral ring composed of fibres impregnated with synthetic resin, a metal hub, and spokes also of fibres impregnated with synthetic resin. These spokes are bonded by adhesive to the inner face of the peripheral ring. The fibres in the peripheral ring are of material having a modulus of elasticity approx. 4 times greater than that of the fibres in the spokes. With this arrangement, due to the much greater stiffness of the fibres in the ring, the spokes expand under centrifugal force by approx. the same amt. as the ring and therefore there is no tension applied at the bonded joint. The flywheel is thus simple to make and does not suffer from the defects of flywheels in which the spokes are wound around the outside of the peripheral ring with consequent break-up of the outer layers of the ring.
Patent DE-3043035-A1 (DE)
Title: Elastics bags stacked for discharge from prodn. machine - on receiving rack alternating with second rack which also presses completed stack
Inventor: SCHULZE EHRHART
IPC: B65H31/30
Filed: 1980-11-14
Abstract: A machine for producing plastics bags (I) comprises a stacking station in which the bags are received on a vertically movable rack (II) as they are delivered, and, when a sufficient stack has been accumulated, are lowered by this rack onto a discharge conveyor. As this stack descends, a second, replacement rack comes into position to receive the first bags (I) for the next stack and accumulates them; during this stage, the completed stack of bags is pressed between the lower side of the replacement rack and the upper side of the receiving rack (II) in order to compress the stack. The control is such that the receiving rack (II) does not descend to the discharge position until after the replacement rack has reached its lowered position to press the sheets. The replacement rack then accumulates the sheets, after which the receiving rack is raised into a position to take over these sheets and form the new stack to completion, after which the process is repeated. The bags can be continuously received without any need to interrupt the receiving process for the previously formed stack to be removed; at the same time the bags on the stack being removed do not slip under the acceleration forces because they have been compressed into a compact stack.

Title: Waste crusher, in particular for garden waste
Inventor: MORDSTEIN JOHANN
IPC: B02C18/22
Filed: 1981-05-09
Abstract: A waste crusher is described, in particular for garden waste, having a cutter disc which, driven by a motor, rotates in a housing to which on the one hand a feed shaft is connected and which opens on the other hand into a flat discharge channel. Safety regulations require measures which prevent a hand passing through the discharge channel to the cutter disc. In order, at the same time, to avoid an obstacle building up in the discharge channel which adversely affects discharging, according to the invention parallel dividing walls are arranged in said channel, which walls gradually rise at a right angle on the one inner flat side, and in the discharge direction up to a spacing, with respect to the flat side lying opposite, which prevents access from the outside. <IMAGE>

Title: Drive for adjusting a member, especially of a bolt element belonging to a motor vehicle
Inventor: BOLENZ KLAUS DR ING
IPC: E05B81/24
Filed: 1981-05-20
Abstract: A drive serving for adjusting a bolt element belonging to a motor vehicle is proposed. The bolt element belongs to the locking mechanism of a covering element assigned to a body aperture. The locking mechanism is provided with a drive unit and with a stop which is arranged between the latter and the bolt element and is movable on a curved track and which, depending on the direction of movement, cooperates with a first or a second movable counter-shoulder bearing against the stop over a specific portion of the track. The counter-shoulders are themselves connected operatively to the bolt element to be adjusted, because, after release by the stop, they can automatically return into their initial positions. The drive is equipped with means which interrupt the movement of the stop before the latter releases the counter-shoulder for the return, so that the counter-shoulder and the bolt element are blocked. <IMAGE>

Title: Conveying device for a transfer line
Inventor: MUELLER KARL-HEINZ
IPC: B65G25/08
Filed: 1981-12-03
Abstract: In a conveying device for a transfer line, the drive unit for the component to be moved comprises a conveying slide which is guided on rails and which can be moved by means of a toothed belt. The drive used for the toothed belt is preferably an electric motor which also controls the braking of the conveying slide before a predetermined position is reached. Thus the braking of moving masses using stops is prevented. The conveying device is suitable for small as well as for large conveying steps, and for driving a plurality of conveying slides via a common toothed belt. By fastening the toothed belt to the first and the last conveying slide, it would then be ensured, in conjunction with a linkage which couples the conveying slides, that the toothed belt is subjected only to tensile stress in the two directions of movement.

Title: Door arrangement for an electromagnetically screened room
Inventor: JOEHL WERNER
IPC: E06B5/18
Filed: 1982-02-08
Abstract: Door arrangement for a room which is screened against electromagnetic pulses (EMP) having an electromagnetic attenuation in the region of 60 dB/1 kHz-120 dB/10 GHz. The flat side (4) of the door frame (1) parallel to the door leaf (5) supports a welded-on profiled frame (7) which has an inner and an outer frame limb (12 and 13 respectively) and a rectangular hollow profile (8). Mounted on its end surface (11) are contact springs (21) whose free tongue ends are supported on the outer frame limb (13) with a contact pressure and which assume the dashed position (q) when the door is in the open position. The door leaf (5) has an edge profile (16) which, when the door is closed, surrounds the rectangular hollow profile (8) without contact and in a flat parallel manner. When the door leaf edge (6) runs onto the contact springs (21) comparatively large spring movements, a large contact area and a large contact pressure result, irrespective of the spring tolerances. When the door is closed, the door leaf region bounding the edge profile (16) furthermore lies on the inner frame limb (12). Subject to planar contact surfaces and a uniform, sufficiently high surface pressure, a door joint with a very small gap width exists in the case of the inner frame limb (12), which gap width forms a transition zone with a very small magnetic and electrical resistance between the door leaf (5) and the frame (1). <IMAGE>
