Patent DE-2836746-A1 (DE)
Title: Digital filter processing rapidly-changing signals - has processor between output D=A converter and input A=D converter contg. counters and volts to frequency converter
Inventor: ZIEGLER HORST PROF DR
IPC: H03H17/02
Filed: 1978-08-22
Abstract: The digital filter has an a-d converter, a programmable processor connected at its input to the converter, a d-a converter connected to the output of the processor, and a clock for these circuits. The a-d converter has a voltage/frequency converter, connected to the filter's input, and two counters connected to its output. A change-over switch is controlled by the clock and alternately connects the two counters to the processor after enabling them. The advantage lies in the filter's handling rapidly-changing signals with relatively few components.

Title: Accumulator housing compressed air leakage tester - has inlet tube housing sealing filler opening with expanding plastic covering
Inventor: RUST GUSTAV ING GRAD
IPC: G01M3/26
Filed: 1979-04-12
Abstract: The accumulator housing leak testing device uses compressed air and has a tube (2) inserted into a filler opening up to a stop collar (9) so as to seal the filler opening and carry compressed air into the housing interior.

Title: Bullet-proof vest - worn over inflatable air cushion
Inventor: APPRICH HARRY
IPC: F41H1/02
Filed: 1979-06-15
Abstract: Bullet-proof vests, made of plates of hard material or of plastic with embedded industrial diamonds, are made more comfortable to wear by interposing inflatable air cushions between body and armour. The air cushions are made of two foils of flexible material which are joined by longitudinal and transverse or diagonal seams to form several separate chambers, each with its own inflation valve. A common hose can join all valves so that the cushion chamber can be inflated from a compressed gas cartridge. Apart from preventing chafing, the cushion compensates for a not 100% fit. It acts also as a life jacket, should the wearer fall into water. The pref. material is a woven tissue coated with polyurethane.

Title: Container ship handling mechanism with guide rails - uses cylinders with pistons engaging container top and bottom for movement along horizontal guide rails
Inventor: CAMPSEN BOLKE
IPC: B65G1/06
Filed: 1979-09-22
Abstract: The system for handling containers (13) stacked on board a cargo ship, uses upper and lower gripping mechanisms (21,22) to move a container horizontally. The containers are supported by horizontal angles (11,12) at top and bottom, acting as guide rails. The gripping mechanisms use piston rods projecting from cylinders (19,20) attached to these rails at top or bottom. These piston rods are automatically released from the container at the end of travel, and the container is then conveyed vertically downwards. Each cylinder is connected by a clamp to the vertical flange of the guide rail, this clamp including a tilting connecting block in line with the axis of the cylinder.

Title: Light meter with filters and transducer shutter - coordinates filter movement, by integral assembly of disc with contact zones for switching
Inventor: OBERTEGGER FRANZ ING GRAD
IPC: G01J1/04
Filed: 1979-10-23
Abstract: Light meter has light filters and an adjustable shutter for screening a light-electrical transducer.

Patent DE-2945764-A1 (DE)
Title: Method of making a wheel rim - uses material with low ductility e.g. aluminium and work hardens certain parts of blank to limit material movement
Inventor: EVANS JAMES L
IPC: B21D53/30
Filed: 1979-11-13
Abstract: The method of making vehicle wheel rims is for use with materials having relatively low ductility, such as aluminium. A circumferential drop centre well is formed about the periphery of the band and work hardened so that the well material exhibits higher strength and lower ductility than the remaining band material. The strength and ductility differential between the well and adjacent band material assists on confining material movement in subsequent rim forming operations and induces drawing of the rim bead seat area material.

Title: Railway permanent way support - using compensating and elastomer layers next to grown soil
Inventor: LANGE KARL-HEINZ ING GRAD
IPC: E01C3/06
Filed: 1979-11-28
Abstract: Ballast for the support of the permanent way of rail tracks rests on the soil foundation through a first compensating layer of sand (5 cm thick) or bitument mortar (5-25 cm).This is overlain by a watertight plastic layer with a high resistance to ageing, before the usual permanent way of broken stone, sleepers and rails is applied. The plastic layer (polychloroprene rubber, polyolefin rubber, butyl rubber, silicone rubber or polyurethane elastomer) has a modulus of elasticity to keep its maximum stress at maximum load within the range of elastic deformation. Both layers below the ballast are secured against side displacement by marginal retainer strips. This creates a road bed foundation for high-speed trains which is not affected in its elastic performance by weather (temp.) conditions.

Title: Detecting vehicle rotation about longitudinal axis - using magnet rotating about conductor with amplifier connected to both ends
Inventor: REISSLAND MARTIN-ULRICH PROF D
IPC: G01P15/00
Filed: 1980-08-08
Abstract: The detector appts. includes a sensor for detecting the vehicle rotation about its longitudinal axis produces a corresp. signal and is mounted in the region of the longitudinal axis, e.g. near the tunnel at the height of the gear lever. The sensor may be electrical or electrodynamic.

The conductor is attached solidly to the vehicle and the permanent magnet is mounted so as to rotate about an axis coaxial with the vehicle longitudinal axis. The arrangement for identification of a rotational motion of a vehicle about its longitudinal axis can detect vehicle decelerations and trigger safety equipment such as safety belt locks and inflatable retention equipment.
Patent DE-3031219-A1 (DE)
Inventor: EGLI ERNST
IPC: B28C7/00
Filed: 1980-08-19
Abstract: The apparatus of this invention feeds coarse-grained, lumpy dry materials from a hopper (1) to an outlet chamber (19) into which materials are blown. It has two rotors (5, 15) that rotate in unison about a common vertical axis and have circumferentially arranged material chambers (24, 25) that are coaxial with one another. A plate (7) between the two rotors (5, 15) has a passage (8) with which the chambers (24, 25) of the rotors (5, 15) can be brought into register by rotor rotation. The upper rotor (5) has a plurality of air chambers (26, 27) which receive pressure air conducted through the passage (8) from each of the chambers (25) of the lower rotor (15). A connecting channel (28) serves to increase the pressure on the outer side of the chambers (25) of the lower rotor (15). Multiple openings into the atmosphere discharge the chambers (24, 26, 27) of the upper rotor (5). With this arrangement the pressure drop  DELTA p is reduced and the distance between a pressurized rotor chamber and an unpressurized one is substantially increased, thereby reducing dust production and wear.
