Patent DE-2132931-A1 (DE)
Title: Cobalt-samarium intermetallic cpd - made by samarium vapour deposition on cobalt powder
Inventor: SCHUELER CLAUS DR
IPC: H01F1/06
Filed: 1971-07-02
Abstract: The intermetallic compound powder, one component of which has lower vapour pressure than the other, is made by placing the two constituents side by side into a common reaction chamber permitting the preferential heating of the high vapour pressure constituent to cause its evaporation and its deposition and reaction with the high vapour pressure material powder. The method is used for making CO-Sm intermetallic compound in a sealed tube which is rotated during heating, and does away with the need for breaking up of the reaction product, which may cause undesirable contaminant pick-up,.

Title: Windbox for atomized fuel nozzle jet - has conical gas nozzle with transverse outlets and baffle to ensure optimum combustion
Inventor: KOCH RAINER
IPC: F23D14/36
Filed: 1973-08-08
Abstract: The combustion air is supplied under pressure by an annular ring while gas is fed by a pipe towards nozzle which exhibits the wide end of its conical outer surface in the direction of gas flow. This causes a restriction in the passage of gases from radial orifices and thus increases the gas velocity towards a hollow baffle with resultant improvement of mixing with air. In addition, the spacing between the base of the conical nozzle and the baffle can be adjusted to meet the local conditions in the furnace. The turbulent region of the burner is enriched with the gas flowing through small bores to enhance the firing rate.

The lock is designed for use with looped combined shoulder and lap belts having three point anchorages but no fastening buckle. The lock retains a belt loop.
Patent DE-2355772-A1 (DE)
Title: Seal for fast running hydrostatically or dynamically supported shafts - consists of elastic magnetic sliding ring which can be lifted by centrifugal force
Inventor: BRAND ARMIN
IPC: F16C33/74
Filed: 1973-11-08
Abstract: A metal ring in which permanent magnets are mounted is moulded into a ring assembly fitted to the shaft housing. A second ring is mounted on the shaft, beyond the ring with permanent magnets inside the housing. This ring is made from non ferro-magnetic materian in which ferro-magnetic inserts are embedded. The inserts pass the permanent magnets in the stationary ring when the shaft rotates. When the shaft is stationary, the sealing lip is pulled against the ring mounted in the housing by the magnets. At high speeds of rotation, centrifugal force tends to lift the sealing lip clear. When the speed of rotation is further increased, induction of the ferromagnetic parts in the second ring will increase the pull of the magnets in the stationary ring, to partly counteract the centrifugal force on the ring.

Title: Formers for twin coils of U-core electromagnets - have hinge-like inter-connection permitting fixing with uninterrupted series winding
Inventor: WIESSNER EDGAR
IPC: H01F27/28
Filed: 1973-12-04
Abstract: The formers for twin coils of U-core electromagnets permit continuous winding of both formers in series and provide for turning into the working position an unambiguous correlation between the two by winding interconnected coils. This is achieved by joining the two formers with each other at a flange by ribbons acting as a hinge. Winding wire recesses are provided on the formers. The wire-connection recesses bring the wires from one former to the other in the region of the rotation axis. At one former flange wire wrap-round points are provided. The advantage of the arrangement lies in the continuous winding facility of both formers in series and in the turning facility of one former into the working position using the winding wire as interconnection between the two coils.
Patent DE-2361005-A1 (DE)
Title: Safety circuit preventing overrunning of crane drives - with contacts to trip the power supply following switch malfunction
Inventor: TRAEGER HANS
IPC: H02H7/08
Filed: 1973-12-07
Abstract: The circuit guards against the consequences of control switch malfunction, for example, due to contacts welding in. The motor control contactors have auxiliary switches, normally closed, in series with a relay whose contact is in series with the main circuit breaker hold on coil. Operating the motor control switch causes a further contact to bridge the auxiliary switches, thus bypassing them when they are open. If, on releasing the control switch, the motor contactor fails to open, the relay drops out as the auxiliary switch has also remained open. Thus the circuit to the circuit breaker hold on coil is interrupted and the supply is tripped. It is advantageous if the relay has a small time delay to allow normal operation of the contacts.

Title: High side pressure hydraulic piston - is charged on one side and has seal to maintain oil against seizing
Inventor: WILLEN CLEMENS
IPC: F16J15/3232

Abstract: The piston is guided with small free play in a cylinder, and has a seal on the pressure side, which engages on the cylinder. The open side of the cylinder has a seal, sliding on the projecting piston end, to wipe-off dirt. The pressure-sided seal and/or the internal cylinder wall, are formed so that a pre-determined amount of pressurized oil is constantly present between piston and cylinder. A ring-shaped collection chamber for pressurized oil is positioned in the cylinder, in front of the end seal. The chamber is in connection with the return, resp. a pressurized oil collection chamber. The cylinder end seal is formed as a double lip seal, with the inner lip projecting into the collection chamber, to wipe the oil off the piston.
