Title: Tension fitting for double-insulator chains in high-voltage overhead lines
Inventor: HILGARTH GUENTHER PROF DR ING
IPC: H02G7/20
Filed: 1983-02-19
Abstract: A tension fitting for double-insulator chains (1, 2) in high-voltage overhead lines has a rigid, plate-like frame (35) which acts as a spacer for the insulator chains (1, 2) and has two upper connecting points (10, 11) for the two insulator chains, and one or more lower connecting points (14) for a conductor cable or conductor harness, the centre of gravity (S) of the frame (35) being located above the connecting line between the two upper connecting points (10, 11), and the frame being connected via hinged fishplates (5, 7), which can pivot parallel to the plane of the frame, to the insulator chains, according to Patent Application P 3201247.0. By means of the invention, it is intended to ensure to an increased extent that the jerky forces occurring in the event of a possible fracture of one of the insulator chains (1, 2) do not lead to a consequential fraction in the second insulator chain which is still intact. It is therefore provided according to the invention that the frame (35) is connected to the two hinged fishplates (5, 7) above the connecting line between its two upper connecting points (10, 11), via damping elements (24, 25) which are bent in a meandering or W-shape and can be deformed permanently. <IMAGE>

Title: Push-on (shoe) heel
Inventor: MUELLER-HEGEMANN NORBERT HEINZ
IPC: A43B3/24
Filed: 1983-03-09
Abstract: The push-on (shoe) heel with enlarged tread area for ladies' shoes, as illustrated disgrammatically in the attached drawing, is characterised in that a partially hollow separate shoe heel is pushed onto the high heel and is held on the heel, which is connected firmly to the shoe, either by the nature of the material or by means of a spring or clamping device. As a result, the shoe can be used optionally with a pointed high heel or solid and safe block heel. Moreover, the push-on heel has an enlarged tread area which can be smooth, profiled or even spiked. The aim of the invention is to increase the practical value of high-heeled ladies' shoes and to produce a safe shoe which on the one hand does not lose any of its elegance for special occasions and on the other hand, by occasional application of the push-on heel, on any ground and in any weather conditions, guarantees safety and comfortable walking. <IMAGE>

Title: Method and device for producing individual short laser pulses
Inventor: SCHAEFER FRITZ PETER DR DIPL P
IPC: H01S3/094
Filed: 1983-05-10
Abstract: A method is described for producing individual short laser pulses, in which a laser medium which can be stimulated is excited by means of a pump pulse in order to produce a population inversion lying above a laser threshold value, and, after the emission of the short radiation pulse, the population inversion is held below the threshold value, which is characterised in that energy is initially extracted from the laser medium, which can be stimulated jointly by two resonators, by means of a first relaxation process at a predetermined threshold value with a relatively short time constant and a relatively low quality, and from the first resonator in the form of the desired individual short laser radiation pulse, and the inversion in the laser medium is subsequently held below the predetermined threshold value of the first resonance process, by means of a second relaxation process, of relatively long time constants and a relatively high quality in the second resonator which is coupled to the first. Furthermore, devices for carrying out this method are specified, which essentially contain two optical resonators of different length and different resonator life, whose optical axes both pass through one and the same active laser medium, which preferably consists of a dye solution.

Title: Operating process for internal combustion engines, and internal combustion engine, especially spark ignition or diesel engine
Inventor: NALBACH HELMUT
IPC: F02B1/04
Filed: 1984-03-16
Abstract: According to the invention, in a spark ignition or diesel engine the combustion peak pressure, which occurs in the area of the top dead centre of the piston, is collected in an accumulator at moderate pressure level, temporarily stored and fed back when the piston reaches a certain distance from the top dead centre and the pressure in the cylinder falls below the accumulator pressure, in that a vessel with flying piston, held in a rest position in the direction of the cylinder internal chamber by means of a spring or compressible pressure medium with adjustable pressure, forms an accumulator volume due to yielding of the piston when the combustion pressure in the cylinder internal chamber exceeds the adjusted pressure.
Patent DE-3411189-A1 (DE)
Title: Automatic door closer
Inventor: TILLMANN HORST
IPC: E05F3/10
Filed: 1984-03-27
Abstract: The door closer has a closer shaft which can be coupled to a door wing and which can rotate from a closing position in both directions of rotation. Within the housing, the closer shaft engages positively by means of a lifting cam disc between rollers of a longitudinally movable slide, on which a spring arrangement forming a working accumulator and the piston of a hydraulic damping device engage. The inner space of the door-closer housing is sub divided into two pressure-medium spaces which are separated by a piston and which are connected by means of separate channels to a respective closable throttle valve for the flow-off of the pressure medium out of the pressure space becoming smaller during the closing of the door and are connected to one another by means of a non-return valve arranged in the piston and likewise opening during the opening movement of the door wing. In this case, the separate channels can alternately be shut off and opened by means of a control slide displaceable by the piston, and inserted in each channel is a safety valve which, when required, connects the pressure-medium spaces. So that the control slide can be placed in its pushed-out position in such a way that the change-over from one return-flow channel to the other can be varied within a specific range of opening angles of the door wing, the stroke end position of the control slide relative to the piston is adjustable.

Title: Circuit for operating light signals for railways
Inventor: MEIER JOACHIM
IPC: B61L5/18
Filed: 1984-05-29
Abstract: For the operation of a light signal with signalling lamps (STOP, GO, SUBSTITUTE SIGNAL) for the stop, go and substitute signal indication, a three-conductor cable is provided between signal box and light signal. The signalling lamps (GO, SUBSTITUTE SIGNAL) for the go and the substitute signal indication are fed via transformers (T2, T3) from an alternating voltage source which can be connected by means of associated actuation contacts (S1/1, ES/4) to one or other outer conductor (1, 3) and to the central conductor (2) of the cable. The two transformers (T2, T3) are connected here to the central conductor (2) via the main filament or secondary filament of the signalling lamp (STOP) for the stop signal. They limit the current flowing across the signalling lamp (STOP) for the stop indication when the go or substitute signal indication is switched on to a value below the glow limit of the respective lamp filaments. In order to switch on the stop signal indication, the associated signalling lamp (STOP) is fed with direct current, the primary windings of the transformers (T2, T3) which are connected in series with the lamp filaments merely constituting low-impedance protective resistors. <IMAGE>

Title: Device for surfboards for the continuously adjustable locking of a mast-foot joint from the wishbone boom
Inventor: BANNASCH LUTZ
IPC: B63B35/79
Filed: 1984-10-16
Abstract: In order to optimally convert the wind force into propulsion during surfing, the sail is put into an ideal position relative to the wind. Once this is achieved, the mast-foot joint could be locked in phases in order to reduce the effort of the surfer. Release of the locking for sail corrections during sailing must always be guaranteed. Serving this purpose is a type of "hand brake", which, by means of two hand levers from the wishbone boom, causes a brake block to act via Bowden cables on the ball surface of the ball-and-socket joint of a mast foot. The brake block lies inside the mast-foot top part in a guide bush and is retained in the latter by means of restoring springs or is fetched back after the release of the locking. For power amplification the cable lines are run over deflection rollers in the mast-foot top part in order to obtain a block and tackle effect. An optimum coefficient of friction, even in water, can be achieved through suitable choice of the material and shape of the brake block. The hand levers enable the effort to be proportioned so that complete locking of the mast-foot joint or a sliding braking effect is achieved.

Title: Compressed-gas circuit breaker
Inventor: HERTZ WALTER DR RER NAT
IPC: H01H33/90
Filed: 1984-11-08
Abstract: In the case of a compressed-gas circuit breaker having electrodes in the form of nozzles, an essentially radial extinguishing-gas supply is released when a switching link (30) is moved. According to the invention, at least one of the electrodes can move and is constructed as a switching electrode (16). The movement is controlled such that the nozzle separation during the power extinguishing phase is favourable to the flow and, after the extinguishing phase, has assumed a dielectrically adequate larger value as far as the end stroke (c). The dielectric strength of the extinguishing system is thus correspondingly increased. <IMAGE>
