Title: Plastics fuel oil tank lug - of plastics impregnated glass fibre strand bonded to top periphery
Inventor: GEISLER NORBERT
IPC: B65D90/00
Filed: 1973-05-05
Abstract: A fuel oil tank made of glass fibre reinforced plastics is fitted with a suspension lug which also consists of a fibre strand, impregnant with plastics. The fibres are spread out in the circumferential direction of the tank and are bonded to it over a part of its periphery.

Title: Guide for linear ball bearing to prevent rotation - esp. useful for tool guide of spark erosion machines
Inventor: STENGEL EDGAR
IPC: F16C29/04
Filed: 1973-08-30
Abstract: The spark erosion tool is attached to the piston which is supported in the cylinder forming part of the guide. The guide slides in the outer cylinder with the bells mounted in the cage, forming a linear ball bearing. V-Grooves are cut in the guide and in the outer cylinder directly opposite each other. Balls of a larger size than the bearing balls run in the V-grooves preventing any relative rotation between the guide and the outer cylinder. Because the grooves extend over the full length of the guide the bearing is also rigidly held relative to its vertical axis.

Title: Modification of controlled rectifier output current regulator - can compensate for operation in discontinuous current region
Inventor: MORE WOLFGANG DIPL-ING
IPC: G05B13/02
Filed: 1973-10-19
Abstract: The application of this modifying circuit is to d.c. output current regulators on thyristor conveters or similar rectifiers feeding resistive-inductive loads in which the current can become discontinuous at certain loads.

Title: Safety interlock for car ignition switch - prevents removal of key with lights switched on
Inventor: KUMP FRITZ
IPC: E05B47/00
Filed: 1974-09-23
Abstract: The ignition switch mechanism is fitted with a safety interlock operated by current flowing through the light switch. This operates a locking bolt to prevent the ignition key from being withdrawn if the light switch is left on. The key can still be turned so that the ignition can be temporarily switched off, or the starter operated if the car is stalled. The driver has to switch off the lights to remove the key, thus reminding him that the lights are on. The system prevents the car being left for long periods with the lights on, thus draining the battery. If the vehicle has to be left with the parking lights on, then they are switched on by the driver after removing the ignition key.
Patent DE-2448725-A1 (DE)
Title: Machine for wrapping conductor groups with metallic sheath - with self centering dies for forming the foil and is used for producing telephone cables
Inventor: PAULAT FALK BODO
IPC: H01B13/26
Filed: 1974-10-12
Abstract: The application is mainly to the manufacture of telephone cables where groups of cores are wrapped in metal foil and sealed to keep out moisture. The metal foil (2) is typically a continuous strip, treated with a synthetic bonding agent, which is wrapped around the core bundle (1) to give a continuous cover with an axial joint. The foil is formed by passing through a series of dies (20) which successively fold it over. Each die is mounted in a slide arrangement (17, 18) permitting vertical and horizontal movement thus allowing it to follow cable irregularities and thereby prevent wrinkling in the sheath. A final heating process seals the sheath by melting the bonding agent.

Title: Cooling-water flow regulator for AC motor - has outlet valve controlled by outlet water temperature to compensate for inlet temperature increases
Inventor: HENSCHEL GUENTER
IPC: H02K9/24
Filed: 1974-11-23
Abstract: The cooling-water flow regulator, which is fitted to a.c. motors which are used in mines, has a regulating valve (3) in the water outlet pipe, and the valve is provided with a temperature sensor (5) which continuously monitors the temperature of the outlet water and is coupled to a thermo-control element (4) that alters the setting of the valve according to the sensor output (i.e. according to outlet water temperature). The advantage lies in reducing the consumption of water and is preventing in a simple manner cooling failure due to a rise in the temperature of the inlet water.
