Title: Ignition of non-hypergolic hybrid fuels - using an adhering thermite mixture
Inventor: SIEGMUND GERHARD
IPC: C06B45/12

Patent DE-2349074-A1 (DE)
Title: Profile rollers for progressive forming of V-shaped reinforcing groove - have eccentric profile elements on roller diameter
Inventor: FEDEROLF SIGHART DIPL ING
IPC: B21D17/04
Filed: 1973-09-29
Abstract: To avoid the uncontrolled deformation which occurs when a flat metal plate is engaged by two profile rollers, a progressive profile increase is required. This is achieved by having the profile elements of the first two rollers eccentric to the main roller body. The synchronization between the two rollers and the feed mechanism is such that the leading edge of the sheet metal plate reaches the first roller pair when both profile elements are at their minimum. Subsequent roller pairs are used to finish the required profile. The profile ring can at least have the width of the first profile roller on the height of the roller circumference. That means that the first profile roller is sufficient to determine the width of the reinforcing plate.

Title: Differential pressure switch for water geysers - controls heating using pressure sensitive resistor acted upon by membrane
Inventor: SCHOENBERGER HELMUT
IPC: H01H35/34
Filed: 1973-10-04
Abstract: The differential pressure switch for water geysers, controls the element heating the water by using a pressure sensitive resistor to detect when the water in the switch low pressure chamber has been drained. The water inlet or high pressure chamber lies on one side of the membrane and the low pressure or outlet chamber on the opposite side of the membrane. The pressure sensitive resistor block is situated in the low pressure chamber at the centre of the membrane. With the membrane undistorted the block resistance is relatively high, e.g. 500 Ohms. When the membrane compress the block the latter resistance is reduced to e.g. 1 Ohm.

Title: Base material for printed circuits - in which copper foil is directly attached to insulation substrate with adhesive
Inventor: MARX KARL-HEINZ
IPC: H05K1/00
Filed: 1974-03-08
Abstract: The method of applying foil using an adhesive is intended to replace the electrochemical deposition of copper on the substrate, especially on flexible materials. The adhesive proposed is a thermoplastic mixture of ethylene polymers which contain, by weight, 1-30% unsaturated carboxylic acid and between 0.01-2% of a metallic stabiliser. The adhesive can be applied to either the copper foil or the substrate, and then cured under heat and pressure, for example between rollers, to ensure adhesion. The bond is proof against subsequent etching procedures.

Title: Tube coupling with retaining ring to prevent withdrawal - has locking pins tightened to compress ring to grip pipe radially
Inventor: KRAEMER KURT DR ING
IPC: F16L27/12
Filed: 1974-04-11
Abstract: The one end of a tube coupling is profiled to provide a secure retaining housing for a ring seal. The tube is inserted into the coupling and is a tight fit against the seal. A cap containing a retaining ring is located over the tube and is moved axially until a stop is contacted. To provide a secure coupling, retaining pins with claw ends are inserted through holes in the cap. Nuts are screwed firmly onto the threaded ends of the pins ensuring that the cap is in positive contact with the flared end of the coupling. An alternative approach employs a profiled ring that is inserted between the cap and the flared end with plain screws used for loading.
