Title: Electromagnetic release mechanism for a single-lens reflex camera
Inventor: KUREI HIROSHI
IPC: A01B63/10
Filed: 1981-01-26
Abstract: In an electromagnetic release mechanism for a single-lens reflex camera, the force which presses a release lever against a locking or blocking bar is cancelled in accordance with an exposure cycle. A pivotably held release lever is connected via a pin to a coupling lever and a magnet armature which can be attracted and held by an electromagnet arrangement. A release spring is wound onto the shaft on which the release lever is seated, and presses with one end, which extends forwards, against a section of a rotatably mounted cocking lever when the latter is in its position or location at the end of a film advance step. When an electric pulse is fed to the coil of the electromagnet arrangement, the magnet armature is released and the release lever strikes against a blocking bar. At the end of an exposure cycle, the cocking lever is in a position of rest without being touched by the release spring, with the result that the release spring now produces no force by which the magnet armature is pressed away from the electromagnet arrangement. <IMAGE>

Patent DE-3108082-A1 (DE)
Title: Potato harvester
Inventor: ROEHRS FRIEDERICH
IPC: A01D33/04
Filed: 1981-03-04
Abstract: In these machines, the lifting member is followed by a screening band which is followed by a rotating leaf band. Between the screening band and the leaf band there is a transfer device, for example in the form of a drum. To make grading possible as early as in the region of the transfer device, it receives in its active surface finger-like elements which are elastically deformable by bending as a result of the impact of potatoes and which thereby execute shifting movements. For this, where a drum-like transfer device is concerned, use is made of axis-perpendicular discs, to which a plurality of these elements are fastened, distributed over the circumference, so as to extend in the axial direction of the drum. Bands can also be used as rotating conveyors, in which case these elements are arranged on transverse bars which are fastened at their ends to rotating belts.
Patent DE-3114073-A1 (DE)
Title: Device for adjusting the braking time of a brake on a conveyor
Inventor: TUESCHEN ALFRED
IPC: B65G43/00
Filed: 1981-04-08
Abstract: The invention relates to a braking device for a conveyor, which device, in the event of braking, brakes the conveyor in a predeterminable braking time, which is independent of the conveyor speed and the load, until standstill. During the braking time, the braking device checks the braking deceleration in the effective braking moment and, taking into consideration the braking time which has already elapsed and the present braking deceleration, calculates the remaining braking time until standstill. If the remaining braking time falls below or exceeds the predetermined braking time, a corresponding adjusting signal for correcting the braking force is produced.

The appliance can be set up under the bed to lift bedridden patients to a favourable height for making the bed, it being possible to merely lift the bed frame covered with a mattress out of the bed frame and lower it again into the same in the case where double beds, for example, are assembled and consequently a bed as such cannot be lifted.
Patent DE-3119989-A1 (DE)
Title: Two-substance or multi-substance compression heat pump or refrigerating machine with solution circuit and degassing of the lean solution by the heat of the rich solution
Inventor: MUCIC VINKO DIPL ING
IPC: F25B25/02
Filed: 1981-05-20
Abstract: The invention relates to a two-substance or multi-substance compression heat pump or refrigerating machine with a solution circuit which has as working medium a mixture of two or more substances, e.g. an ammonia/water mixture. The concept of the invention is to increase the performance number of the respective machine. The solution to this aim consists in using the technically usable heat of the rich solution completely or partially for the further degassing of the lean solution, the further degassed component or components of the mixture preferably being resorbed by the rich solution and in particular in such a manner that the absorption heat thus released is required for the further degassing of the lean solution. Herewith, the maximum resorber temperature sought can be achieved at a lower pressure than without this measure and the refrigerating capacity of the machine can be increased as by these means the further cooling of the rich solution is made possible.
Patent DE-3121335-A1 (DE)
Title: Stroke setter
Inventor: EHRENTRAUT FRANZ-JOSEF
IPC: F02D11/08
Filed: 1981-05-29
Abstract: In a stroke setter having a pneumatic or hydraulic diaphragm cell, a control-pressure space on one side of a diaphragm which is under the spring prestress of a diaphragm spring can be so connected to two pressure connections of different pressure levels that any control pressures between the two pressure levels can be set in the control-pressure space in relation to a diaphragm space on the other diaphragm side by means of at least one controllable valve. The at leat one valve is loosely coupled to the diaphragm spring via a tensioned valve spring. A force transmitter assigned to the valve makes it possible, by the entry of an electrical desired value, to generate a force corresponding to this and acting on the valve counter to the valve spring. Thus, by the input of the least possible electrical control powers, the diaphragm of the stroke setter can, by the utilisation of the pneumatic or hydraulic pressure energy, be brought into a position corresponding to the desired value and be held in this.

Title: Abrasive material on underlay with novel base material
Inventor: ANDRESEN ARNE DR
IPC: B24D11/02
Filed: 1982-01-25
Abstract: The invention relates to the production of an underlay which is improved in comparison with paper and cheaper in comparison with finished fabric for the production of high-quality flexible abrasive materials. The production of the underlay is performed in the following way: a suitable adhesive is applied to a layer of paper or film. A thermally or chemically bonded nonwoven is laminated thereupon with a high peel strength. The further processing of this underlay into a finished, flexible abrasive material is performed in a known way, it being possible for the paper side and the nonwoven side or the film side of the underlay to be strewn with binder and abrasive grain. The finished flexible abrasive material can then be processed in a known way into endless abrasive belts or other manufactured forms. The abrasive performances of the finished abrasive belts correspond in the case of the strewn nonwoven side to those of high-quality abrasive cloth belts at lower costs overall, in the case of the strewn paper side to those of paper belts with a substantially increased resistance to tearing and tear propagation.

Patent DE-3208942-A1 (DE)
Title: Machine gun
Inventor: KOINE RICHARD ING GRAD
IPC: F41F1/08
Filed: 1982-03-12
Abstract: The machine gun has two complete weapons (200) in a cradle (10), in a common weapon housing (70). The weapons are permanently connected to one another in a positively locking manner in the region of their base pieces (201) by means of a mechanical coupling device (120.2), and are coupled to one another in a positively-locking manner in the region of collars (216) (on the respective barrel 214) by means of a hydraulic coupling device (120.1) while firing is occurring. The mechanical coupling device (120.2) is part of a transmission (122) for driving the two breeches (230). The latter have a straight tension characteristic and a rotatable breech head (238) with locking means. Whilst both weapons (200) - they are constructed as recoil loaders - can move axially for alternating positive running in the weapon housing (70), the weapon housing (70) is guided during a central preliminary movement buffering (87) and by means of a recoil running-out spring (89) in the cradle (10) for axial to-and-fro movement. At least in the respective outside region (202), each base piece (201) is shaped as a secondary part (270), which, with a stator (260) which is arranged in an adjacent manner on the cradle side, forms a linear motor (250) in each case. When opening fire, the linear motors (250) replace a clamping device and, in the event of predetermined control, enable the operation of both weapons (200) above or below a natural, system-intrinsic cadence region. <IMAGE>
