Title: Connector for HV rotary isolator - has flexible connectors between moving and fixed parts arranged in parallel circumferential paths
Inventor: SZYGULLA HEINZ
IPC: H01H1/58
Filed: 1979-11-16
Abstract: The rotary connection between the moving and fixed parts of the isolator comprises two similar cup shaped contacts (2,3). These are located coaxially on a pivot pin (4) allowing one contact to turn with respect to the other. The electrical connection between contacts is made by flexible cables (5). These have terminal lugs (8) for bolting onto the flat inner surfaces (6,7) of the contacts (2,3). All the lugs are positioned tangentially in the same direction to imaginary circles centered on the pivot pin (4). Several flexible connectors are arranged in parallel side by side. The chamber formed by the cup shaped contacts is sealed by a gasket (11) on the mating faces of their cylindrical sides (10). The flexible connections are thus kept free from contamination. The connector arrangement safely withstands short circuit currents.

Title: Broad band operational amplifier for video signals - with voltage amplification in one transistor stage with associated impedance converter and current control transistors
Inventor: LEHMANN KLAUS
IPC: H03F3/50
Filed: 1979-12-17
Abstract: A pair of emitter connected transistors (1,2) are controlled by field effect transistors (6,7) connected to their respective bases. The common emitter connection is taken through a third transistor (3) to one pole (24) of the supply. In association with a further transistor (4) the former (3) represents a high impedance current source. Common mode signals on the input electrodes (12,13) of the FETs (6,7) thus have no influence. The collectors of the amplifying transistors (1,2) are connected through further transistors (10,11) to the other supply pole (25). These transistors ensure that there is equal current flow through each amplifying transistor, and also act as the output impedance of the amplifier. The output is taken from the common collector connection (2,11) to an output impedance converter circuit (14,15). In most cases phase correction can be made by adjusting the current flow through the transistor (3) in the amplifier emitter leads.

Title: Opto:electronic coupler - between light emitter and receiver by light guide plastic with filler
Inventor: KLANN JOERG ING GRAD
IPC: H04B10/80
Filed: 1980-03-27
Abstract: An opto-electronic coupler consists of an optical light guide plastic which couples a light transmitter to a light receiver, both of the semiconductor type. The light guide plastic includes a filler which is transparent for the emitted wavelength and the receiver sensitivity, e.g. quartz powder (cf. up to 30 mu) or glass beads (of up to 50 mu). If the surrounding case is an epoxy resin moulding compound, with a thermal expansion factor of 30 x 10 power minus 6 cm per deg.C, the factor of the light guide plastic is adopted to it by the filler. This also forms molecular bends which raise the breakdown strength. This reduces the stresses, caused by greater temperature fluctuations.

Title: NC system for cutting grooves in cylindrical surfaces - utilises microprocessor program which controls start and end of grooves of variable pitch and length
Inventor: POEHLMAN LAWRENCE C
IPC: G05B19/18
Filed: 1980-07-11
Abstract: The system comprises a machine tool which cuts grooves of variable pitch and length under control of a programmable microprocessor subsystem. Moreover the start and end position of the groove or grooves may be programmed with the entire groove taking up less than 360 degrees, principal applications being cable drums or lubricating channels in cylindrical bearings etc. The grooves may be cut into cylindrical or cone shaped surfaces of any angle. The paper tape reader (41) provides the program for a numeric control interpolator (40). The resulting data (XVC,ZVC,THETZ.VC) are converted to analogue signals (45,46,47) to result in control signals (Vx,V3,Vtheta) where Ve determines the start and end position of the grooves. Three position sensors (Rx,R3,R theta) produce the three position feed back signals for comparison in the control system (40).

Title: Calibrating acoustic flow meter - by electronically simulating transition time delays in situ.
Inventor: KRAUSE GERHARD
IPC: G01P21/02
Filed: 1980-07-31
Abstract: The transducers emit alternate pulse packets in opposite directions with and against the flow. An electronic evaluation circuit determines the flow speed from the packet transition times or speeds of sound in both directions. The calibration is performed by electronically simulating the different pulse packet transition times corresp. to defined flow speeds. This is effected by placing a delay circuit between the input of a modulator and the output of a demodulator. The delay unit has a changeover facility operated synchronously with the transducer changeover switch.

Title: Push-button switch having a pushbutton in the form of a cap
Inventor: SCHRUMPF HANS
IPC: H01H13/14
Filed: 1981-03-28
Abstract: A push-button switch having a plastic pushbutton in the form of a cap is proposed which, in its quiescent position, is pressed by spring elements against a housing stop. The push-button switch is designed such that resetting and assembly are as simple as possible and that clattering of the pushbutton in the event of vibration is prevented. For this purpose, the pushbutton (12) is provided on its lower edge (12a) with two mutually opposite spring tongues (19) which are supported against the switch housing (11) when the pushbutton (12) is in the quiescent position. When the pushbutton (12) is operated, the spring tongues spring back into suitably shaped recesses (21) in the pushbutton (12) so that they reset the pushbutton to its original position again after operation. Such a push-button switch can be used both in the case of momentary-contact switches and also in those switches which are alternately switched on and off whenever the pushbutton is operated. <IMAGE>

Title: Sleeve connection for the ends of in each case two lengths of pipe
Inventor: ARNDT VOLKER
IPC: F16L21/00
Filed: 1981-05-30
Abstract: The invention relates to a connection of lengths of pipe, to be rammed into the earth, by means of a sleeve and consists in that, when the pipe-length ends are cylindrical, the sleeve has cone surfaces running approximately from the centre or, when the sleeve is cylindrical, the pipe lengths have cone surfaces running to their ends. After forcibly pushing the sleeve over the pipe-length ends or pushing the sleeve into the pipe-length ends, said cone surfaces and a sheet-like part located opposite have different diameters in order to produce a radial deformation pressure on the pipe-length ends, the pipe-length ends coming to bear against an annular flange of the sleeve or the sleeve ends coming to bear against a stepped wall portion of the pipe-length ends.
Patent DE-3128927-A1 (DE)
Title: Method and device for image pattern recognition
Inventor: EXNER KLAUS-UWE
IPC: G06V10/88
Filed: 1981-07-22
Abstract: The method relates to an image pattern recognition in which positive and negative images are brought to coincide. In this process, a transparent negative image (10) is brought to coincide with a current transparent or non-transparent positive image (9) via imaging optics (8). For this purpose, the amount of light (11) impinging on or passing through the negative image (10) via the imaging optics (8) is barrier-integrally recorded and measured by means of a photosensor (12) in the total field of the negative image (10). The criterion for recognising an image pattern is a transgression of a threshold value for the signal ratio (b:a) or the signal difference (b-a) for the required image pattern in the viewfinder field. A zero crossing of a differentiated signal variation as a function of time is counted as locating and recognition of the required image pattern. During this process, the signal value is moved to the extremes, and the associated azimuth angle is picked up, in the case of angle errors. <IMAGE>

Title: Decachloro-o-carboranyl compounds substituted by functional groups and their use
Inventor: GABEL DETLEF PROF DR
IPC: C07F5/02
Filed: 1981-10-26
Abstract: One of the problems in the technical management of boron neutron capture therapy of tumours is the adequate localisation of boron in the target tissue. Such a localisation can be tested successfully if biologically active molecules having a differential affinity for the target tissue are modified with boron compounds such that their activity and affinity are retained. For protein in particular, it is demanded here that the chosen boron compound is stable to hydrolysis and the solubility of the protein is not reduced. B-decachloro-o-carboranyl compounds are suitable for this purpose, since they are polar and charged in physiological pH ranges. They can be bound to proteins without their solubility being reduced.
