Patent DE-2717483-A1 (DE)
Title: Fish storage chute on processing machines - with U=profile and retarding flat rail along centre (PT 2.5.78)
Inventor: HELGESEN WILLY
IPC: A22C25/08
Filed: 1977-04-20
Abstract: A chute for the temporary storage of fish between fish processing machines has a cross-section with a rounded bottom to match the shape of fish. A flat rail is suspended from braclets and runs longitudinally along the chute at a height which is adjustable. Arrangement is less likely to lead to jamming by fish than the conventional closed tubes. The trough can be adjusted to different fish sizes by varying its height.

Patent DE-2735767-A1 (DE)
Title: Magnetically stabilised fluidised bed - with controlled flow of fluidising fluid
Inventor: KAMHOLZ KENNETH
IPC: C07C1/04
Filed: 1977-08-09
Abstract: An improvement is claimed for stable operation of a fluidised bed of solid magnetisable particles in an external force field (esp. gravity). The fluidised bed is produced by exposing the bed of particles and a fluidising fluid (esp. a gas) to a constant uniform magnetic field having a substantial component along the direction of the external force field such that the particles have a component of magnetisation (M) along that direction. The improvement lies in the fact that the flow of fluidising fluid, which opposes the external force field, has a superficial velocity V1 such that V2  V1  V3 (where V2 in the minimum superficial velocity required to fluidise the bed in the absence of the magnetic field, and V3 is the superficial velocity required to cause time-varying fluctuations of pressure difference through the bed over a finite period (esp. 0.1-1 sec) during continuous fluidisation in the presence of the magnetic field). The stabilised fluidised bed can be used to carry out catalytic reactions (e.g. cracking), gasification or combustion of coal, removal of solids from gases, etc. The stabilised bed is like an expanded fixed bed, combining the properties of a normal fluidised bed (particles do not clog, solids throughput can be achieved) and a fixed bed (no solids circulation or gas by-passing, particles can be trapped). Instability due to time-variance of the magnetic field is avoided (cf. US 3440731).

Title: Drive system for tape recorder - has two driving wheels for fast rewind, and further, small wheel driven through friction coupling and driving winding reel
Inventor: LAUFER HELMUT
IPC: G11B15/44
Filed: 1977-09-24
Abstract: The tape is wound off from a reel by a tone shaft, and wound on the other reel driven through a friction coupling by a motor whose speed is not much above the maximum reel speed. This motor also drives a drive coupled to the one or the other reel for fast rewind. Two driving wheels (5, 6) on a swivelling arm (2) are driven in opposite directions by a stationary motor (25) through a belt. Tilting the arm (2) in one of the two directions couples the wheels (5, 6) with one or the other shaft (8, 9) driving the reels. A third driving wheel (20) with a smaller dia. is connected with the wheel (5) through a friction coupling. It can be coupled with a fourth driving wheel (12) on the shaft of the winding up reel.

Title: Collector of airborne particles - directing them by high velocity capturing nozzle into container with decelerating air cushion
Inventor: SCHWARZBACH ERIK DR
IPC: C12M1/26
Filed: 1977-12-07
Abstract: A collector for airborne particles, esp. for live spores of barley mildew, is a container with a small opening at the top, surmounted by a nozzle for the intake and acceleration of the aerosol particles. They are passed into the container, decelerated by the air trapped in it, and form a sediment across the bottom of the container. The high velocity required to capture the airborne particles is thus gradually reduced to achieve a slow sedimentation on a capturing substrate.

Title: DC-free multilevel block code generation - by multiplying elementary code words by different factors before combining
Inventor: SCHEHRER RUDOLF DR ING
IPC: H04L25/48

Patent DE-2834304-A1 (DE)
Inventor: SCHERRER IGOR
IPC: G04G5/00
Filed: 1978-08-02
Abstract: An electronic watch is set to the proper time by correction of the content of counters of the watch through the actuation of one or both of two switches. The actuation of the first one of the switches selects whether the content of the counters is to be incremented or decremented at a first speed. The subsequent actuation of the other switch performs the correction at a second higher speed in the sense selected by actuation of the first switch.

Patent DE-2915336-A1 (DE)
Title: Adsorption dryer for compressed gases - having cold adsorbent regeneration by pressure swing using one changeover valve and one pressure reducing valve
Inventor: HERTER KURT ING GRAD
IPC: B01D53/04
Filed: 1979-04-14
Abstract: Adsorption type dryer uses the cold regeneration pressure swing cycle. The moist gas is taken into one of a pair of adsorber beds where the moisture is removed. The dry gas leaves from the other end of the bed. The bed is regenerated by diverting the moist gas to the other bed. The pressure in the bed is then vented and a flow of gas at lower pressure is taken from the product gas stream via a pressure reducing/non-return valve. The outlet side of the beds are controlled entirely by non-return valves and there is only one changeover valve and one pressure reducing valve. Used for drying gases at high pressures esp. 100 to 400 bar. Is of simple construction yet gives minimum usage of gas for the low pressure phase of the cycle by avoiding pressure balancing between the two beds on changeover and with minimal usage if the compressor is shut down.
