Patent DE-2927245-A1 (DE)
Title: Plastic welding strip - with inflated hose in carrier beam groove to back metal strip for compensating uneven surfaces
Inventor: SCHMEDDING HERBERT
IPC: B29C65/00
Filed: 1979-07-05
Abstract: A pulsed welding strip for thermoplastic foils or for packing material coated with thermoplastic material consists of a carrier beam with a U-shaped opening at the bottom in which an inflated hose is inserted. The welding strip with the contacts at the end confines the protruding hose in the groove and is held in place by a PTFE tape. The hose is made of silicone rubber or PTFE and is filled with air, nitrogen or oil. This makes the welding strip flexible enough to follow even irregular surfaces, for example when a different number of foils produces a step along a weld. It also compensates any thermal distortions of the welding strip itself.

Title: Side reflector graphite block - with grid of slots terminated by cross bores defining wear zone
Inventor: ELTER CLAUS DR ING
IPC: G21C11/06
Filed: 1979-07-26
Abstract: The cylindrical side reflector of a gas cooled high-temperature reactor consists of rings of graphite blocks, stacked above each other. The inward faces of the graphite blocks have a grid of parallel slits. Each slit is terminated at the bottom by a hole across, with a diameter equal to a multiple of the slit width. The distance of these cross holes from the face corresponds to the thickness of the wear zone. This eliminates the high notch stresses, caused by simple joints. The wear zone is now relieved from any structural stress.

Title: Joiner for connecting coaxial cables - has two half shells and internal conductor support for introducing cable ends radially instead of axially
Inventor: WAIDNER FRANK
IPC: H01R9/05
Filed: 1979-09-11
Abstract: A supporting piece (1) having an integral spring (2) is set in the half shell (3) ready to accept the coaxial cable. The cable has a sheath (4) which is partly bared, and is gripped by projections (5) when the two half shells (3) are screwed together. The stripped portion of the cable (6), lies in a constriction (7), in the half shell for the purpose of making contact. The support (1) for holding the bared inner conductor (8) consists of two side walls (11,12) and a crosspiece (13), and is crosspiece (13) of the support (1), and has arms (18-21). The spring ends (23-26) of the arms serve to clamp the inner conductor (8) of the cable to be connected. This method allows coaxial cables to be joined by placing the two ends together in a radial rather than axial manner.

Patent DE-2939458-A1 (DE)
Inventor: WOBORSCHIL WALTER DIPL ING
IPC: G09G1/02
Filed: 1979-09-28
Abstract: A system for localizing a region of a display incorporates a plurality of resettable counters for defining the position and extent of a cursor in two dimensions, such cursor comprising at least two non-parallel lines defining an open frame. Data is set into the counters periodically at the beginning of each frame, or at the beginning of each scanning line, so that the size and shape of the cursor is selectable, as well as its position on the display. When the data is modified during successive time periods, the cursor can be made to progressively reduce its size so as to indicate a point, and/or to progressively change its location.

Title: Phase sensing esp. for optical chopper rotating motor - uses electronic trigger circuits forming pulses from stator voltages
Inventor: PAUL BERNT DIPL PHYS DR
IPC: H02P6/14
Filed: 1979-11-14
Abstract: A phase sensor for a rotating system is esp. suitable for an optical chopper driven by a d.c. motor with an electronic commutation circuit. The phase signal is produced partic. simply using an economically constructed compact sensor which can also be used other than for rotating chopper systems. The current leads of the motor stator (2) windings (6 to 9) are each connected to the input of an electronic trigger stage (52 to 55) consisting of a Schmitt-Trigger or a null voltage comparator. A three-phase output is produced by summing the positive output pulses of two trigger circuits (53,55). The phase sensor converts the rotater voltages into sharp pulses which can be used to mark defined positions of a chopper wheel. It uses the built-in motor phase sensing magnetic field rotation.

Title: Flowmeter for measuring low liquids flow rates - uses restricted inlet cross=section of body displacement annulus
Inventor: BRAEUTIGAM ROLF
IPC: G01F1/05
Filed: 1980-05-16
Abstract: The flowmeter, pref. for liquids, has an annular channel in a sealed housing. The liquid enters the channel via a tangential inlet (15), drives rounded bodies (17), pref. spheres, part a measurement point, and leaves via an outlet (16). The arrangement has an inlet of relatively narrow cross-section compared to the channel and outlet so as to produce more acceleration of the spherical bodies at the sensor (19) position and thus enable smaller flow rates to be measured than with conventional arrangements. The outlet (16) is also tangential to the channel (14). The specific wt. of the rounded bodies (17) is approximately equal to that of the liquid in the annular channel. The inlet is in the form of a nozzle whose cross-section is no more than half that of the outlet.

Title: Resistance welding control - by controlling welding pressure or current firing-phase angle according to welding voltage
Inventor: NAKATA SHUJI
IPC: B23K11/25
Filed: 1980-08-14
Abstract: The resistance welding control method comprises (i) detecting the voltage (Vc) between the electrodes through which a.c. welding current is flowing, (ii) generating a series of predetermined reference welding voltages (Vo) based on a reference voltage curve w.r.t. time measured in cycles of the welding current, (iii) computing the difference between the detected voltage (Vc) and the reference voltage (Vo) and (iv) controlling the welding pressure or current firing phase angle applied to the electrodes in accordance with the voltage difference. Pref. each half-wave peak value of the detected voltage (Vc) is held for a half-cycle before voltage comparison, the welding current flowing through the electrodes is held constant, and a start-stop signal is emitted to control the constant current and a timing signal (Tp) is emitted for synchronisation. Additionally, a base voltage (Vo) is pref. preset and the difference between Vc and Vo is intergrated only when each half-wave peak value of Vc exceeds the level voltage Vo. A stable welding quality is obtd. by controlling the welding voltage by changing the electrode pressure, even if the supply voltage fluctuates.

Title: Process for controlling the degree of drying in a laundry dryer
Inventor: JORDING WOLFHARD
IPC: D06F58/38
Filed: 1981-01-29
Abstract: The process is aimed at controlling the degree of drying of the laundry in a program-controlled laundry dryer, its use seeming to be advantageous especially in a dryer of the drum type with microcomputer control. The control of the degree of drying is carried out by means of different measuring methods according to the desired residual moisture content. With a degree of drying of relatively high residual moisture, in the initial phase of the drying process the temperature change in a specific unit of time is determined and the subsequent drying time is preprogrammed as a function of this. In contrast, with a degree of drying of relatively low residual moisture, the temperature-difference measurement is utilised.

Title: Method and device for measuring, evaluating and dosing the quantity of flash light in the case of microscope photographs
Inventor: MEYER OTTO
IPC: G03B15/05
Filed: 1981-03-13
Abstract: Because of the impossibility of guiding the flash over the microscope onto the sensor, it has not to date been possible to apply commercially available computer flash units having an external sensor in the case of flash photomicrographs. In order to provide the remedy here, and to permit the use of a computer flash unit in conjunction with an arbitrary camera when making photographs by means of autodynamic control of the flash light emission, it is proposed to combine a microscope with a timer unit which is equipped with a light-measuring probe which is introduced into the beam path of the microscope tube and upon the emission of flash light conveys to the timer unit a number of pulses which is proportional to the volume of light received, which pulses are used in turn at the instance when a desired illumination threshold stored in the timer unit and formed from the film sensitivity, photograph format and the dazzling effect inherent in the microscope beam path is exceeded to cause a secondary light source which is mounted on the external sensor of the flash unit and flashes up without inertia to emit light, and the camera shutter located in the open position to close.
