Title: PTC resistor cct. for motor current reduction - bridges capacitor in AC supply line to reduce high current values after starting
Inventor: JAENICKE PETER DIPL ING
IPC: H02H9/02
Filed: 1973-12-03
Abstract: The PTC resistor circuit reduces an electric motor supply current to below its initial switch-on value required for starting. The PTC resistor bridges a capacitor in one of the supply lines to the motor windings. The resistor is heated by the high starting current and its resistance increases as its temperature rises, thereby reducing the supply current to a magnitude compatible with the motor normal running current requirements. The PTC resistor circuit replaces a multi-stage transformer with a tap changer. The motor braking windings may be connected in series with oppositely poled diodes across the a.c. supply on the motor side of the PTC resistor circuit.
Patent DE-2404698-A1 (DE)
Title: Soldering iron with electromagnetic suction plunger in bit - for sucking molten solder out of joint when desoldering
Inventor: KIRSCH UDO WOLFGANG
IPC: B23K3/02
Filed: 1974-02-01
Abstract: The soldering iron has a built-in electromagnetic suction device, achieved by using a soldering bit with a central, longitudinal hole which is coated with a layer of plastic and which contains a plunger fixed to a soft iron plate. An electromagnet is located in the upper part of the iron and, when switched on it attracts the iron plate, thus drawing the plunger upwards and creating suction; when the electromagnet is switched off the soft iron plate is drawn downwards by a permanent magnet, thereby ejecting the solder drawn up into the bit by the upward stroke of the plunger. The solder bit is threaded on its upper end so it can be located in the soldering iron, and the permanent magnet is pref. sepd. from the heating element by a layer of insulation. Used for sucking molten solder off a soldered joint, e.g. during desolering. Operation is very rapid so the molten solder is sucked out of the joint before it has any chance to solidify. The device is only the size of a conventional soldering iron.
Patent DE-2414118-A1 (DE)
Title: Die casting machine injection pump - with cylinder and ring made of materials of differing coeffts. of expansion
Inventor: NAKAMURA HIROMI
IPC: B22D17/04
Filed: 1974-03-23
Abstract: A plurality of contact surfaces are provided to permit relative movement of the cylinder and the stationary ring and the extensions of the contact surfaces intersect each other at or near a neutral point of expansion of the cylinder. Upper and lower guide rings may be positioned about the stationary ring to surround the cylinder and the contact surfaces are then formed between the stationary ring and the guide rings. The material of the stationary ring has a larger coefft. of expansion than that of the materials of the cylinder and guide rings. The pump is used in a hot chamber-type die cast machine. The cylinder and stationary ring are maintained in concentric relation when they thermally expand and molten metal is prevented from reading the contact surfaces between the cylinder and ring. Materials other than ceramics can be used for component parts other than the cylinder.

Title: Oxygen detector for exhaust gas has solid electrolyte tube - shielded from thermal shock and abrasion by catalyst particles
Inventor: LINDER ERNST DIPL ING
IPC: F02D35/00
Filed: 1974-04-05
Abstract: A measuring device for determining the oxygen content of exhaust or waste gases, esp. from internal combustion motors, comprises an electrochemical sensor consisting of an oxygen concn. cahin with ions-conducting solid electrolyte in the form of a tube closed at one end; upstream of this tube, in relation to the flow direction of the gas, there is a catalyst. Used where accurate determn. of the oxygen content is required, esp. with high sensitivity at the transition from reducing to oxidising state of the gas measured. The presence of the catalyst shields the sensor from thermal shock resulting from direct contact with the exhaust gas and from the impact of small particles in the gas. At the same time, the electrochemical properties are retained. Thus longer life of the sensor is achieved.
Patent DE-2418147-A1 (DE)
Title: Detent action car door hinge - has rotary hub with radial notches meshing when open with corresponding stationary notches
Inventor: BLUEGGEL ERWIN
IPC: E05D11/10

Title: Oil pressure cut out system for marine engine - shuts off, or reduces engine speed when lubricating oil pressure drops below pre-determined margin
IPC: F01M1/22
Filed: 1974-04-30
Abstract: Marine engine with control installation to switch off when the lubricating oil pressure drops below a pre-determined safety margin. The control system is pneumatically actuated and is connected to an air pressure source through a pressure pipe in which a valve is located adjustable between two positions, one permitting the maintenance of a pre-determined pressure, and two preventing this pressure. The control has a cylinder with a piston adjustable within it with the piston rod carrying the valve. One side of the piston reacts directly to the lubricating oil pressure, so that a predetermined reduction in that pressure adjusts the valve into the second position.
