Title: Liquefied natural gas tanker - with storage tanks on load bearing elements with foam plastics thermal insulation
Inventor: BECKER RUDOLF DIPL ING DR
IPC: F17C3/02
Filed: 1973-09-29
Abstract: A tanker for liquefied natural gas is fitted with a heat insulated hold contg several cylindrical storage tanks. Each tank is supported by a carrier element of poor heat conductivity against the ship's bottom. The space between the tanks is filled by a prestressed non-load-bearing, insulating material (pressed foam plastics). This prevents the formation of cracks during the temp. changes in the hold. The use of foam reduces the wt of the insulation.

Title: Setting mechanicm for magnetic field sensitive S-C resistor - has rotating bolt driving permanent magnet and indicator pointer
Inventor: KELLER WERNER
IPC: H01L43/08
Filed: 1973-11-22
Abstract: The setting mechanism, for a magnetic field sensitive semiconductor resistor, has a rotating hollow bolt with an external thread to drive an indicator pointer, and an internal thread to drive a second bolt down onto the movable permanent magnet. Rotating the first bolt moves the second bolt axially and the pointer axially down the outside of the first bolt.

Title: Coating appts. for paper etc webs - has slotted nozzle supplying coating substance onto support roll carried web width
IPC: B05C1/12
Filed: 1973-11-29
Abstract: The coating apparatus for running lengths of paper, cardboard, or plastics has the coating mass applied by a slotted nozzle over the entire width of the web length which partially wraps a support roll and if necessary then smoothed. The tubular nozzle body is conventionally elastically deformable to vary the outlet gap and is enclosed by pairwise-opposed clamping pieces, which are independently pivotably about specified points of rotation. Preferably there are divergent extensions of the gap in the region of the free ends of the clamping pieces, with a spacing determining the gap width and the spacing from the support roll, the metering gap width and of the return gap. Adjustability of the gap is increased and improved in a simple manner.
Patent DE-2402077-A1 (DE)
Title: Locking castor for chairs - has roller blocking mechanism which releases the roller by pressure from above
Inventor: GROSS WALTHER DIPL ING
IPC: B60B33/02
Filed: 1974-01-17
Abstract: The roller rotates on an axle anchored on the two sides of a housing partly enveloping the roller. Part of the housing is designed to serve as seating for the vertical swiveling axle mounted in a bushing. Between the outer surface of the bushing and inner surface of the seating a layer of resilient material is fitted. The swivelling axle has a downward extension terminating in a brake shoe which, at the chair's unloaded condition, presses against the roller surface to provide the blocking action. When the chair becomes loaded reaction forces from the eccentrically positioned horizontal axle deviate the swivelling axle from it's true vertical position due to the resilient inlay and the roller surface detaches itself from the brake shoe so that it can move freely.

Preferably the heated ventilation air from the refrigeration plants is forced as required by a fan through its space-heating circulation. More particular the apparatus has changeover ventilating flaps and a fan between the cold plant chamber and the space-heating area.
Patent DE-2405466-A1 (DE)
Title: Load maxima monitoring device - performs continuous comparisons of loads over constant periods of time
Inventor: BILZ WILHELM
IPC: G01R11/64
Filed: 1974-02-05
Abstract: The device delivers signals depending on load; it has a differential gearing whose sun gear drives a pointer and can be connected to a counter, and another sun gear driving a comparator (time) pointer and can be connected to a suitable clockwork; its cross shaft interacts with a signal contact which, when the measurement pointer overruns the comparator pointer, trips an optical or acoustical signal. The signalling is controlled by load, so that when a specified load is exceeded, signal pulses are delivered, and when a specified limit is exceeded, a continuous signal is generated; when the excess over the specified load increases the duration of signal pulses also increases.
Patent DE-2413110-A1 (DE)
Title: Towing hook for car - has cylindrical shaft welded to precut U-shaped beam

Abstract: An inverted U-shaped beam is mounted on the towing frame attached to the car and has its open end cut in such a way as to fit around the cylindrical shaft of the towing ball. The shaft is then attached to the beam by seam welding along the joining line. The construction is simple to prepare and requires a relatively simple stamping for the towing ball. The beam is also simple to attach, and the whole assembly provides a strong, economic, and easily engineered construction. For added strength the beam can have converging sidewalls whose final spacing is nearly the diameter of the cylindrical shaft.

Title: Liquid filled electric motor - is pressure-proof and water-tight for under water operation
Inventor: JENSEN POUL DUE
IPC: F16J15/34
Filed: 1974-07-10
Abstract: The motor has a chamber above the sealing arrangement filled with water for pressure equalising and lubricating of the motor shaft. The shaft extends through the enclosure and holds a rotating slip-ring (8) which slips against a non-rotating slipring (16) fixed to the enclosure and forms a seal. The non-rotating slipring (16) is connected to the enclosure by means of a rubber support membrane (6) with its outer circumference and to the shaft via slipring (16) so that there is a passage (23) for water between the gliding surfaces. The slip rings are arranged to part from one another during motion due to pressures set up in the chamber by overwinding the spring mounted inside the sealing chamber.

Title: Door closer with spring and damping unit - has pneumatic spring and lever for ensuring closing force variation
Inventor: LUTZ DIETER DIPL ING DR
IPC: E05F3/00
Filed: 1974-07-30
Abstract: The closing element has a pneumatic spring whose line of action is at right angles to the rotating axis of the door, and pivoted, with a housing mounted on the door or door frame. The piston rod of the pneumatic spring is connected by a drive to a support on the door frame or on the door and this support rotates relative to the housing. The drive system is formed by a lever connected with the support (6). The end of this lever is connected directly to the piston rod (4) of the pneumatic spring. This arrangement forms an eccentric pivot relative to the rotating axis of the door. The closing force is markedly reduced due to the position of the lever in the support in opening of the door from a certain opening angle. A holding force can also be generated.
