Title: Hybrid thick film circuit esp. miniature voltage stabiliser - comprising semiconductor diode mesas attached to plates of capacitors on dielectric substrate
Inventor: HAMBOR JOHN GEORGE
IPC: H05K1/18
Filed: 1978-08-24
Abstract: Hybride thick film circuit with dielectric substrate is formed by applying to one surface of the substrate a pattern of metallisation to form capacitors, and on the opposite surface a corresp. pattern of metallisation is formed in alignment with the members of the first pattern. Semiconductor-mesa-elements having an under surface metallised are aligned with the upper surface metallised areas of the capacitors and bonded to them so as to make direct electrical contact with the capacitors. These mesas have an upper surface to which a lead wire can be (s) attached. The other end of the lead wire is attached to the capacitor metallising layer of an adjacent capacitor mesa assembly, or to the metallising of the opposite surface of the dielectric substrate. The undersurface metallising layer is formed in two strips, connected electrically to opposite supply terminals. The wires connecting mesas with capacitor plates are connected across the width of the substrate to correspond with the opposing plates of the appropriate underside connecting stiip. The arrangement forms a miniaturised voltage stabiliser which can be produced with a low failure rate using thick film technology. Opt. the substrate is divided into two parts, insulated from each other with epoxy resin.

Title: High power protective device - has spark gap and small protective resistor in series and disconnector opened by UV sensor detecting spark
Inventor: SCHNEIDER BERND DIPL ING
IPC: H02H1/00
Filed: 1978-11-29
Abstract: The protective device has a spark gap and a protective resistor in series. Current flows from a current source over the spark gap. A disconnector interrupts the flow of current through the protective resistor when a spark appears across the spark gap. A radiation sensitive device(7) responds to the radiation emitted by the spark as it crosses the gap and controls the disconnector. The radiation sensitive device contains a u.v. sensor. The advantage lies in being able to use a lower power protective resistor. It is applicable to a high power transmitter.
Patent DE-2854520-A1 (DE)
Inventor: KLEIN ERWIN
IPC: H01F5/00
Filed: 1978-12-16
Abstract: The coil winding (1) consists of a braided wire which consists of a relatively large number of conductor strands which are interleaved with one another in the form of a flexible tube in such a manner that the individual conductor strands change their position on the circumference of the flexible tube to such an extent that they in each case assume every possible position with respect to the flexible tube axis, at least over the length of one turn of the winding in each case. A tube (4) through which a coolant flows is wound with the winding (1), which tube (4) has a flattened profile and consists of a non-magnetic, electrically insulating material. The coil is finally potted, with a potting resin (9), in a vacuum. The invention is suitable for commutating inductors, which can be highly loaded, for converter installations. <IMAGE>

Title: Stand-by current monitor for alarm in electrical circuit - has monitoring circuit which allows reset of circuit to prevent reactivation of alarm indicators
Inventor: GORKA WILFRIED DIPL ING
IPC: G08B29/06
Filed: 1979-01-22
Abstract: The monitoring arrangement is for an alarm system and maintains a check on the quiescent current in alarm connecting lines to ensure that false triggering does not occur. In particular, the system avoids problems associated with an increase in voltage following an alarm state cancellation, where the alarm indicator, e.g. flasher can be re-activated. A number of feed units (ES1 to ESn) are used to control the triggering of alarm units to produce activation of the flashing display. As soon as the voltage from the mains (NT) falls below a specified value, the triggered alarm drops out and a control signal (LS) is detected by the monitoring stage (US). As soon as the supply voltage begins to rise, the alarm indicator is activated once more. This may be prevented by operating a reset (RT).

Patent DE-2919852-A1 (DE)
Inventor: BLASCHKE FELIX DIPL ING DR
IPC: H02P21/00
Filed: 1979-05-16
Abstract: A control unit for regulating an asynchronous motor supplied with power from a three phase network by a line-controlled power converter which is DC coupled to a self-commutated inverter has a function generator and a current regulator which controls the stator current of the motor by the controlling rectifier valves in the inverter. Control of the stator current is a function of a predeterminable value of flux fed into the function generator. In a parallel control system, an actual-value computer and a load state control regulate the stator frequency by generating a signal for controlling the self-commutating converter as a function of the actual values of the stator current, the stator voltage, and a value calculated from the function generator input variable. The computer forms signals corresponding to the amplitude of the flux vector, and to a stator current component perpendicular to the flux vector. A variable derived from the predeterminable variable is applied to the load state control as a reference value. Fall-out-proof, low oscillation, speed control is effected from low angles to nearly 90 DEG .

Title: Slide fastener with high lateral strength - having hollow members locked together by internal cylinders operated by longitudinal draw-cord
Inventor: CERNY ALEXANDER DR MED
IPC: A44B19/20
Filed: 1979-05-30
Abstract: A slide fastener comprises one set of interlocking elements having a wide longitudinal bore through the heads of the elements and a longitudinal slot in the ends of the heads which connects with the bore. The wide bore of a second set of elements extends not quite fully along the length of the head, with a small central bore for the remainder of the length. A rod or wire runs the complete length of the second series of elements passing through the smaller bores of the heads. Regularly-spaced cylindrical nodes on the rod or cord are housed within the larger bores of the heads. When the two sets of elements have been intermeshed by means of a slider, the cord is used to draw the cylinders into the bores of the now contiguous first set of elements, thus locking the two series firmly together. The fastener has a higher lateral breaking strength than conventional fasteners. The outside form of the members can be varied widely, widening the range of applications and the aesthetic appeal.

Title: Self-ejecting plug for electrical socket - has bracket release spring-loaded cap which moves out from front face
Inventor: WOLTER PETER
IPC: H01R13/635
Filed: 1979-09-13
Abstract: The plug has a helical spring (3) inside a cap (2) between the pins. When the plug is inserted into its socket, the cap is pushed into the plug and the spring is compressed. The cap has a lip that passes over the end of the spring-loaded release bracket (4). The bracket then moves to the right and holds the cap in its 'in' position. Moving the bracket to the left releases the lip and allows the spring to push the cap outwards thereby separating the plug from the socket without having to pull. The bracket has a small helical spring (6) under tension tending to pull it to the right. It can only move to the right when the lip of the cap passes over the bracket's end -- ie rear. The user uses his finger to move the bracket back to the left against the action of the small spring.

Title: Injection of carbonaceous fuel or oxygen into molten iron - using spring loaded valve; esp. for steel-making converters
Inventor: FASSBINDER HANS-GEORG
IPC: C21C5/34
Filed: 1979-12-11
Abstract: Below the surface of molten iron in a vessel, e.g. a converter, are tuyeres embedded in the refractory brickwork in the vessel. Either fuel suspended in a carrier gas, or oxygen, is fed to the same inlet channel leading to the tuyere, and esp. into an inner tuyere tube, which is concentrically surrounded by an outer tube fed with gas- or liq- hydrocarbons. The alternate feeding of the fuel in its carrier gas, or oxygen, is achieved using a valve with two seats. In one position of the valve, only oxygen flows to the tuyere inlet pipe; in the other position of the valve only the fuel in its carrier gas flows into the tuyere inlet pipe.. The method is esp. suited to the converter steel making described in DE 2838983, where coal or coke can be blown into the converter. Tuyere blockage by the solid fuel is avoided.

Title: Stenter-chain drive mechanism with transverse drive belt - and horizontal drive pinions continuously displaceable along belt
Inventor: LUEPNITZ GERHARD
IPC: D06C3/00
Filed: 1980-02-16
Abstract: The pin or clip chains of a stenter pass around horizontal chain wheels rotating around a vertical axis, and connected by vertical shafts to horizontal drive pinions. The pinions on each side of the machine are driven by a single motor via an endless drive-belt which crosses transversely the full width of the machine, whereby the drive pinions may be displaced along the drive belt to vary the separation between the chains. Auxiliary pulleys give an arc of contact of the drive belt with the drive pulley of 1/3 - 3/4 of the circumference, and at least one of the drive shafts connecting a pinion to a chain wheel incorporates a differential gear. This is a simple, inexpensive drive which ensures uniform speed of the two chains, or a precisely-adjustable speed differential between them.
