Patent DE-2836548-A1 (DE)
Inventor: WIRZ WALTER
IPC: B27N1/02
Filed: 1978-08-21
Abstract: Such an apparatus contains a cage roller (12), rotatably arranged by a hollow vertical axle (1) in a shaft (2), which cage roller flings the particles under the action of centrifugal force against the inner side of the shaft and in such a manner forms the rotationally symmetrical curtain of falling particles. The cage roller (12) is open on the top side for feeding the particle material and is closed on the bottom side by a base (13). Such a cage roller acting as distributor element requires less drive energy and ensures the generation of a particularly uniform, untangled and dispersed particle curtain, for example of wood chips, which are to be sprayed with a binder, for example glue. <IMAGE>

Patent DE-2854582-A1 (DE)
Title: Transport frame for glass panes - is equipped with cams fitted with counter hooks inserted into holes and having slot between hook and carrier
Inventor: JUERGENS WALTER DR ING
IPC: B65D85/48
Filed: 1978-12-18
Abstract: A slot of a thickness equal to that of the material exists between the counter hooks and the glass carrier. This is designed so that in the event of a slight sideways movement of the glass carrier the material is located between the hook and the base carrier. The device is intended to prevent the jumping of the cams from the holes during strong shaking of the vehicle which used to damage the base metal, caused a tilting of the glass base supports and damaged the glass panes.
Patent DE-2857589-A1 (DE)
Title: Permanent magnet rotor synchronous motor - has salient pole stator with part of pole tip width on each pole reduced by alternative stator punching positioning
Inventor: DROEGE CARSTEN ING GRAD
IPC: H02K21/16
Filed: 1978-09-28
Abstract: The stator punching blank is modified such that, when stacked into a complete core (2), part of each pole is reduced, at the tip, to give a wide and narrow (4, 3) part of the tip on each pole. Such a core is produced by designing the stator punching in a manner that allows simple reversal of the punching during stacking in order to produce the required pole tip arrangement. The extra effort in manufacture of the modified stator is thus very small. The pole tip design raises the maximum output for a give frame size. The application is typically to small synchronous motors as used in measuring or regulating circuits, which have a power output of about 50 watts maximum. The proposed design modification is intended to optimise run up and stable running characteristics, and also to reduce noise.

Title: Spring-biased pastry cutting shape - has one open point closed by spring and easily opened for release of shaped dough
Inventor: LAUFER HUBERTUS
IPC: A21C11/10
Filed: 1979-02-13
Abstract: The actual cutting mould (1) is open at one point (4) on its perimeter so that after being placed into the dough etc. it can be compressed. It is compressed pref. against a resetting force prod. by a spring force which spreads out the cutter shape (1) at its opening. Dough, esp. that used for making fancy cakes or the like can be pasty so that it can compress inside the mould whereby the mould becomes closed and the dough is correctly shaped. The shaped dough is then completely released from the surrounding dough and then easily removed. Once the shaped dough is placed on the baking sheet the mould is opened again allowing easy transfer to the sheet.

Patent DE-2920148-A1 (DE)
Title: Pendulum passenger and luggage transport train - has only last vehicle stopping for rapid boarding and alighting in containers
Inventor: BEINECKE DIETRICH DIPL KFM
IPC: B61B13/00
Filed: 1979-05-18
Abstract: Travelling time is reduced on a rail system with no additional acceleration sectors needed, and passenger disembarkation and luggage unloading are simplified. This is achieved by stopping only the last coach of a train at each station. Passengers and luggage, accommodated in containers, are unloaded. Simultaneously, new ones, previously mechanically loaded into other containers, are loaded on and the vehicle starts, catches up with the train, and is coupled to it again. The system is also designed to save energy as only a part of the train is decelerated and accelerated.

Patent DE-2923513-A1 (DE)
Title: Appts. for measuring physiological response time - has electronic circuit using counter or ramp generator for measuring elapsed time between stimulus and response
IPC: A61B5/16
Filed: 1979-06-09
Abstract: Reaction time monitor may be used for practical training for sport, police or military application. A visual or audible signal is produced and the person responds by pressing a switch, possibly in the form of a pistol or rifle trigger. This produces a visible light flash or invisible infra-red beam which strikes a photocell in a target. The signal starts a counter (4) which counts the pulses of an oscillator (8), the count being decoded so as to produce an indication of the elapsed time in seconds. The oscillator could be replaced by a ramp generator which is started by the starting signal and stopped by the response signal, the final voltage being a measure of the elapsed time.

On the recording head rests a potentiometer slider. The appts. has a servomotor whose shaft carries a drive roller, coupled by an endless, flexible toothed drive belt to reversing rollers on the ends of the linear guide, as well as to the recording head. The servomotor is controlled by a measuring signal, the potentiometer serving as position indicator. The toothed belt is elastically stretchable in longitudinal direction, and is wrapped round under tension round the drive and reversing rollers. All the rollers are in the form of gears in mesh with the belt teeth. At the recording head, the belt is held between a support surface, abutting the belt smooth side, and a toothing engaging the belt teeth.
