Patent DE-2746585-A1 (DE)
Title: Waste water smell blocking flap valve - has two flaps actuated by spring ensuring water draining and closing
Inventor: SCHMITT HERBERT
IPC: E04D13/08
Filed: 1977-10-25
Abstract: The waste water smell locking closure has two flaps on a common shaft. These flaps are pushed upwards by common spring for closing a tube. This valve prevents escape of smells and vapours from waste water tubes by preventing reverse flow of water and gases. The flaps and the spring are made of acid resistant material. If water is collected on the flaps then the weight of the collected water opens these flaps downwards. The water can drain away and after draining has been completed the spring pressure from below ensures closing of these flaps.

Title: Upright portable hopper for dry plaster - has square-section top part and inverted pyramid base in support frame
Inventor: WILDGRUBER HELMUT
IPC: B65D88/26
Filed: 1978-03-01

Abstract: The heat-damped component is used for connection of two metal profiles, so that at least one insulated fillet (3b) engages with arms in back-cut grooves in the profiles and has a hollow chamber with inclined surfaces. By pressing wedge-shaped braces into this chamber the insulated fillet is tensioned into position. The fillet comprises a single profile which during the bracing process is broken into two parts along a theoretical break point. Various other versions of the fillet involve single or two part structures, two wedge-shaped fillets joined to make one, or a hollow profile open on one side.
Patent DE-2814809-A1 (DE)
Inventor: PELLANT MICHAL DIPL ING
IPC: H01L23/367
Filed: 1978-04-05
Abstract: In the liquid-cooling appliance for cooling a semiconductor component, which has been brought into contact with this appliance, a coolant is introduced through a feeder (3) into a cooling chamber of a base body (2) which is at least partially enclosed by a housing (1), and is passed out again via a discharge (4). In this arrangement, the heat exchange takes place via the base body with which the semiconductor component in question is in contact. Baffles (6 and 8) are employed to induce turbulence in the flowing coolant and thus to achieve considerable heat exchange by avoiding laminar boundary layers. <IMAGE>

Patent DE-2817645-A1 (DE)
Inventor: UEDA MAKOTO
IPC: H02P8/00
Filed: 1978-04-21
Abstract: An analog electronic timepiece has a stepping motor for rotationally driving the timepiece hands. The motor is driven by normal driving pulses during normal load conditions and in the event the normal driving pulses are unable to effect rotation of the motor, correction driving pulses of longer pulse width than the normal driving pulses are used. A detection circuit detects whether or not the motor has rotated by switching a resistance element in series with the motor drive coil after the application of each normal driving pulse. Rotation and non-rotation of the motor is determined by measuring the voltage across the resistance element and comparing the measured voltage with a reference voltage.

Title: Diesel engine viscous-hydraulic angular oscillation damper - incorporates heavy ring suspended in fluid springs stressed in one direction
Inventor: FEDERN KLAUS PROF DR ING
IPC: F16F15/173
Filed: 1978-04-24
Abstract: The oscillation damper for the drive with a small to medium sized high speed diesel engine consists of a ring shaped heavy mass which is mounted with minimum clearance in a ring shaped housing. Damping action is carried out by the viscous shear forces of the fluid in the narrow gaps and by the inertia of the mass. The mass is attached to the housing by C shaped leaf springs which encircle the centreline about which the mass oscillates. The springs are designed and stressed so that the bonding moment over the length of the spring remains of the same sign (i.e. positive or negative).

Title: Vehicle shock absorbing buffer - has socket joined to housing front replacing draw rod, springs and wedge
Inventor: XHALUPNIK RUDOLF ING
IPC: F16F13/00
Filed: 1978-11-25
Abstract: The mechanism is esp. used as a buffer in railway vehicles. Typically a sleeve type housing has internal front end sections for guidance of a friction wedge device. There is bottom rear end opening for passage of a bolt type draw rod stressing intervening springs. The draw-rod with springs and friction wedge of the known mechanism are replaced by a socket unit firmly connected to the housing front end. The exterior of this fits the front inside section while its cylindrical inside walling guides a buffer cylinder with the piston front end subjected to pressure and supported on an inset piece spanning the opening in the bottom of the housing. This permits rapid and easy conversion into a device with significantly increased impact capacity but with the same thrust.
Patent DE-2851661-A1 (DE)
Title: Pipe coupling with wedging contractible ring - is disengaged by moving pipes manually inward and inserting thin half circular sleeve tool
Inventor: RUMBLE EDGAR BERT
IPC: F16L37/092
Filed: 1978-11-29
Abstract: Annular grooves inwardly from the ends of the coupling define circumferentially tapered channels in which contractible rings are disposed and arranged. Forces tending to separate the pipes and the couplings will move the contractible rings axially along the tapered surface of the channels in the coupling into locking engagement with grooves around the pipe sections. Moving the pipe sections inwardly of the opposite ends of the coupling and inserting tools between the pipe sections and the coupling engaging the contractible rings in the areas of the circumferentially tapered channels causes the contractible rings to be expanded therein sufficiently to permit the pipe sections to be withdrawn from the coupling.
