Patent DE-2821926-A1 (DE)
Inventor: SPOERER BERNHARD
IPC: B65G1/12
Filed: 1978-05-19
Abstract: An assembly apparatus which is particularly useful in the manual assembly of circuit carrier plates with electrical components is formed with an upwardly facing working surface having thereon a support member for the carrier plates, with a plurality of receptacles for holding components to be mounted on the carrier plates being operatively located beneath the working surface. The receptacles are supported for guided movement beneath the working surface through an uppermost and lowermost plane and an opening in the working surface is provided through which an operator seated at the assembly apparatus may grasp components from receptacles located in the upward plane for mounting upon a carrier plate supported on the support member. The supporting means comprise a guide track loop operating to bring the receptacles individually into position within the uppermost plane where they will be accessible through the opening, the guide track loop defining a generally horizontally extending loop axis about which the guide track loop extends, with each receptacle being suspended from the guide track loop in the manner of a pendulum from a pendulum axis extending generally parallel to the loop axis. The superposed planes through which the receptacles are moved are spaced apart a distance such that the working surface may be located at a level which may be conveniently reached by an operator seated at the assembly apparatus while permitting sufficient space for the knees of the operator to extend beneath the receptacles located within the lowermost plane.

Inventor: HARMS HARM-DIEDRICH DIPL ING
IPC: H02M7/162
Filed: 1978-05-20
Abstract: It is intended to specify a control and turn-off device for the main thyristors, which are arranged in a bridge circuit, and the turn-off thyristors, which are likewise arranged in a bridge circuit - with a turn-off capacitor located in the bridge diagonal - of a pulse-controlled converter, which control and turn-off device ensures high operating reliability of the converter and low on-state power losses in the main circuit of the same without any additional components. This is achieved by means of a logic circuit whose inputs have logic signals G, K, B and F applied to them, the logic signal G being emitted for the magnitude and the logic signal K for the polarity of the capacitor voltage from a measurement converter (10) connected in parallel with the turn-off capacitor (9), and the logic signal B being emitted for the polarity of the pulse-controlled converter input current and the logic signal F for free wheeling or switched-through operation by a regulating device (14) which has a higher ranking than the control device, and its outputs being connected to the control connections of the main thyristors and turn-off thyristors (1 to 8). <IMAGE>

Title: Soil improving agent or gardening compost contg. cork - with the addition of a nitrogen fertiliser to counteract the growth inhibiting effect of the cork
Inventor: HAERTLE JOSEF
IPC: C09K17/48
Filed: 1979-03-02
Abstract: Comminuted or ground bark is mixed, without composting, with a nitrogenous fertiliser, opt. with the addition of soil, peat or the like. The amount of nitrogen to be added is ca 400-600mg Npsr litre of ground fresh bark, regardless of whether the nitrogeneous fertilizer is added before or after mixing the bark with peat. Inclusion of the nitrogeneous fertilizer counteracts the growth-inhibiting effect of bark, which is attributed to depletion of available nitrogen.

Title: Optical system for measuring angles, distances, or speeds - uses intersecting image formed from lines of photodiodes successively scanned for evaluation
Inventor: HAAS RUEDIGER ING GRAD
IPC: G01D5/26
Filed: 1979-03-13
Abstract: An optical system for measurement of angles, distances or speeds working on the collimation or autocollimation principle involves formation of a test image contg. two intersecting lines on a photodiode array contg. two intersecting lines of diodes. The diodes of each line are successively scanned and the results of both lines evaluated to determine the relative positions of the image and diode line intersections. The system enables a result to be evaluated irrespective of the relative thicknesses of the image and diode lines. The test image has a regular geometric figure centred at the assumed crossing point of the two image lines, which are terminated at the edges of the figure. For evaluation of diode output pulse series the crossing point is identified as the centre of one pulse train or the centre of the gap between two pulse trains.

Title: Rotary IC engine - has circular piston revolving eccentrically in circular cylinder forming two spaces between them
Inventor: JAEGER LOTHAR
IPC: F01C1/04
Filed: 1979-04-20
Abstract: The engine has a cylindrical piston (1) which is mounted on a crank (2) on the shaft and revolves eccentrically in a circular cylinder (7).

Title: Appts. for actuation of switching element - has double solenoids actuated to provide braking and avoid impact condition
Inventor: HEUSS OTTO
IPC: H01F7/18
Filed: 1979-06-05
Abstract: A control circuit for controlling the operation of a two state switching device with double solenoid actuation, avoids, impact conditions, and may be used in electric organs. The armature (4) of the actuator is moved up or down by selective operation of one of two solenoids (2, 3). The solenoids receive command signals (5) over a decoder (9) to trigger monostable transistor drive stages (6a, 7a). Gating elements (11, 14 and 12, 13) connect the two channels. In operation, when a command to actuate one solenoid (2) is received, the gutting element (11) signals the other channel (14) to provide energisation of the other solenoid (3) after a suitable delay. This provides a controlled braking of the armature (4) thus avoiding impact.

Title: Additives for oil recovery by polymer flooding - comprising dispersion of acrylamide polymer in oil
Inventor: KEGGENHOFF BERTHOLD DR
IPC: C09K8/588
Filed: 1979-06-27
Abstract: Viscosifying additives for water-flooding media comprise nonaq. polymer-in-oil dispersions contg. a water-soluble acrylamide homopolymer or copolymer with up to 25 wt.% acrylic acid, dispersed in an organic hydrophobic liq. The dispersions are produced by (a) polymerising acrylamide or a mixt. of acrylamide and acrylic acid (and/or its water-soluble salts) in a w/o emulsion by irradiating with UV light in the presence of a photoinitiator, and (b) azeotropically dehydrating the resulting polymer emulsion to a water content of less than 5 wt.% based on the polymer. The additives dissolve rapidly in water to form a low-viscosity homogeneous soln. which gradually increases in viscosity over 3-4 hr. They have good salt tolerance and shear stability.

Title: Fastener for housing contained stator - has groove(s) in inner housing contact surface and/or outer stator surface, coupled to connecting passage for pressurised medium
Inventor: SCHROEDER PAUL
IPC: H02K1/18
Filed: 1979-07-14
Abstract: The stator (1) contained in a housing (5) is secured there by pressing or shrinking. Between the contact surfaces (4', 8') of the stator and housing are provided grooves (9), which can be filled with pressurised oil etc. in case of a dismantling operation. In such instance a film is formed between the contact surfaces, enabling the removal of the stator from the housing. The groove is connected to a coupling passage (10) in one housing wall (5') with a connecting bore (11) for pressurised oil supply. The outer contact surfaces (4') of the stator are preferably formed by outer surfaces of the stator press rings (4). The inner contact surfaces (8') of the housing may be formed by inner contact surface of clamps (8) incorporated in the inner housing wall. This arrangement enables assembly and dismounting of the stator without damaging any fastening components. The secure fastening reduces also stator vibrations.
