Title: Nickel foil to aluminium component connection - uses combined ultrasonic and resistance welding
Inventor: RASKE HANS-ERICH
IPC: B23K20/10
Filed: 1977-09-27
Abstract: The aluminium component is a sheet metal cathode element for an electron tube, and the nickel foil forms the connecting tag for this element which has to be secured to its contacting point by thermal treatment. The connection of the foil and the element is carried out by resistance-ultrasonic welding. The metal parts to be welded are preheated prior to welding by a voltage between 2 to 4 V and a pulsed current of 150-500 A. During welding the sonotrode pressure force is limited to 100 N/sq. mm.

Title: Automatic welding of conductor ends to plug contacts - uses conductor shaping tool for extreme bending of conductor ends to disrupt insulation
Inventor: SCHMIDT MANFRED
IPC: H01R43/28
Filed: 1977-11-08
Abstract: The automatic welding is intended for ends of flexible, multi-core conductors with plastics insulation. It provides connection to plug contacts etc., and the individual core ends are shaped into acceptable form by a shaping tool (12, 13). The conductor core ends (11) are subjected to bending stresses in the shaping tool in such manner that the insulation is subjected to a stretch exceeding its elasticity modulus. Preferably the shaping tool is fitted with very sharp bending edges. This process eliminates the need for special holders otherwise required for welding plug contacts etc. to the ends of cable cores.

Patent DE-2807390-A1 (DE)
Inventor: PETRITZ PETER
IPC: D03D47/26
Filed: 1978-02-21
Abstract: The weft regulator has a sensing member (9) which is pivotable from a position of rest towards the desired position of the weft thread (5) last inserted and not yet thrown and which assumes one of two pivoting positions, depending on whether this weft thread is present or absent, in a specific time interval after the desired position is reached. The movement of the sensing member (9) up to the desired position takes place solely by means of a positive drive (14, 15, 16, 22) and subsequently the sensing member (9) is subjected to a non-positive drive (11, 18), of which the force effect on the sensing member (9) is lower than the holding force of a correctly inserted weft thread (5). If the weft thread is present, the sensing member (9) remains, during the specific time interval, in its first pivoting position assumed when the desired position is reached, and if the weft thread is absent the sensing member (9) is moved from the desired position into the second pivoting position by the non-positive drive (11, 18). <IMAGE>

Title: IC engine distilled water injection unit - has water flow controlled by needle valve, and solenoid operated by accelerator pedal
Inventor: BRUEHLMANN EMIL
IPC: F02M25/022
Filed: 1978-07-08
Abstract: A constant level tank (3) contains a float (10) which operates a valve (9) to admit distilled water from a reservoir (4) so as to maintain a constant level in the tank. The water flows from the tank to a nozzle (14) through which it is injected into the engine suction manifold. The flow through the nozzle is controlled by a needle valve (13). The needle is retracted against a spring by a solenoid (15) to open the valve. The solenoid is energised from the engine battery by a switch (21) operated by the accelerator pedal (20). The addition of water results in a combustion of fuel air mixture which leaves no pollutants in the exhaust and reduces the tendency to knock. Fuel without additives can therefore be used.

Title: Projector drive motor digital control - uses speed signals from LED acting on phototransistor to feed logic system and activate counters
Inventor: BOROWSKI KURT ING GRAD
IPC: H02P7/288
Filed: 1978-07-21
Abstract: The object is to allow smooth and accurate variation of film speed either between set limits or over a selected number of frames. A digital speed signal is derived from a light emitting diode acting on a phototransistor through a perforated disc attached to the camera. The resulting output impulses are then fed to the digital logic system. The speed dependant impulses are used to control two digital counters, one resetting to zero and one acting as an up-down counter. When an equilibrium is reached an output acts on the motor power controller.
