Title: Vehicle constant supply fuel tank - has two pumps and subsidiary chamber to ensure sufficient fuel while cornering
Inventor: HENNING BODO
IPC: B60K15/077
Filed: 1974-12-19
Abstract: A special subsidiary fuel chamber is fitted inside the main fuel tank and both the tank and the chamber are connected to separate fuel pumps by separate fuel lines. The fuel pumps may be separately driven or fitted to a common motor shaft. The return fuel lines from the pumps are taken together in a single line back into the chamber, from where any excess overflows into the main tank. The fuel supply from the chamber is thus always ensured, even when the vehicle corners and the fuel is thrown to one side of the main tank. A warning system can be fitted to indicate to the driver when no more fuel is being drawn from the main tank, so that he knows that he is running on the reserve from the chamber.
Patent DE-2461252-A1 (DE)
Inventor: RAHN PAUL
IPC: B21L3/02
Filed: 1974-12-23
Abstract: The machine has two chain guides (16, 17), of which one rises and the other falls, with respect to the point at which the welding is carried out. A saddle (1) is located beneath the welding point. The end edges (20, 20') of the guides (16, 17) run at a distance from each other, from the saddle (1) and in a horizontal direction, with the result that, once the conveying displacement is complete, in each case the two chain links (31, 32), neighbouring the chain link (27) to be welded, rest with in each case two chain-link legs on the end edge (20, 20'). Consequently, the chain link (27) to be welded is automatically aligned at least in an approximately perpendicular manner, under the stress, brought about by the weight, of the neighbouring chain links. It is thus possible to weld the links, following directly one after the other, with one passage of the chain. <IMAGE>

Title: Compact instrument transformer for breakdown voltage testing - has windings on laminated cone diametrally above laminated ring closing core ends
Inventor: GRUNDMARK BENGT DIPL ING
IPC: H01F38/18
Filed: 1975-07-03
Abstract: The instrument transformer is intended for breakdown voltage testing of high voltage components and consists of a three-layer coil (2) wound onto a laminated axial core (3) and located diametrally above a laminated ring (6) that acts as magnetic closure piece for the ends of the axial core. The ring thus presents two flux paths between the core ends. The laminations of both the core and the ring are at right angles to the plane of the ring. The ends of the core pass into support yokes (4) that direct the magnetic flux down towards the ring. All the coil windings are arranged on a straight laminated core shank. The advantage of the transformer lies in its relative compactness.

Title: Offshore drilling platform with oil storage containers - manufactured separately and coupled to foundation structure through expansion joints
Inventor: HEINRICH ROBERT DIPL ING
IPC: B65D88/78
Filed: 1975-08-08
Abstract: An offshore drilling platform with a structure resting at the bottom of the sea has in the foundation cavities which are used to float it into position and later for storage of the produced oil. These storage cavities are designed as modules independent of the base pads on which the platform legs rest. They are connected to the base pads and to the cross ties joining the pads by expansion joints. This compensates for any constraints set up in the storage cavities when oil which may have a temperature of up to 90 degrees C is pumped into them. Cracks and premature destruction are thus eliminated.
Patent DE-2539944-A1 (DE)
Title: Austenitic manganese steel weld deposited on railway rails - using automatic welding under controlled conditions to avoid stress
IPC: B23K35/30
Filed: 1975-09-09
Abstract: The weld is deposited using a filler wire 2-4mm in dia. with a welding current of 450-580 amps. at 30-32 volts. The burner nozzle is 30-50 mm from the weld which is made at a speed of 60-80 cm per minute. The process can be applied for the building up of worn railway rails or for providing new rails with wear-resistant deposits on their working surfaces. Reduced welding stresses occur when this process is used, so that subsequent straightening of the rail is minimised or avoided.

Title: Knitter lock action - has a profiled needle butt to give a bridge between channels to reduce breakage
Inventor: BAUER HERBERT
IPC: D04B15/32
Filed: 1975-10-27
Abstract: A knitting machine lock apparatus is claimed with an angled face on the needle butt which is positioned, according to direction of travel, to range onto a second lock channel before it has fully cleared the first lock channel, to act as a bridge between the two channels. The system allows needle and sinker operating speeds to be increased, without incurring the risk of component breakage as the operating forces are contained and movement distortions are prevented.

Title: Electric levelling instrument - contains two liquid switches which break contact when two reference edges are not exactly horizontal and vertical resp.
Inventor: PILKAHN DIETER
IPC: G01C9/20
Filed: 1975-11-12
Abstract: The electric level determines whether or not a plane is horizontal or vertical, using two liquid switches (4). These are so arrangement that their contacts (5) are only connected, via the switch liquid, when the two reference edges (2, 3) of the housing (1) are exactly horizontal and vertical, respectively. The liquid in the switches may be mercury or water with a substance added to increase its conductivity.

Title: Press mounted in drawer for household waste - has press motor lowering ram onto support block for transport
Inventor: FAERBER KARL-HEINZ ING GRAD
IPC: B30B9/30
Filed: 1975-12-13
Abstract: The household waste press is mounted in a cabinet which can be built in with matching kitchen furniture. The waste material is placed in a drawer (13) which slides open in a direction at right angles to the movement of the press ram. During transport of the press e.g. from the factory, a block (22) is placed in the bottom of the drawer. By operating the drive motor (19), the press ram (18) is lowered and placed under pressure against the block. The pressure is large enough to prevent relative movement between the drawer and the press.

Title: Differentiation system between PBX trunk calls to different zones - is based on different return signals from public exchange with local and remote calls using dissimilar pulse times
Inventor: REINHOLD ANDREAS
IPC: H04Q3/62
Filed: 1975-12-20
Abstract: Return signals from the public exchange marking both trunk (FG) and local (NG) calls, are charge pulses modulated with an ac voltage. Pulse train (P1) for local calls differs from the pulse train (P2) for trunk calls in at least one respect. An evaluating device (BE) at the PBX evaluates the difference between the return signals, and marks the PBX extension connected to a distant subscriber. In a typical arrangement the pulse train for the local calls (I1) is longer than that of the remote calls (I2).
