Title: Microfilm reader film control - has key-pad and store to control detailed motorised X and Y axis film movement
Inventor: SCHUMACHER HELMUT DIPL ING
IPC: G03B21/11
Filed: 1978-12-13
Abstract: The microfilm reader equipment has a keypad control of the film movement. The keypad supplies a 5 bit code word to the motor control circuitry so that the film can be moved back and forth in both x and y directions on the film plane. The keypad (1) sends into a coder (2) which is connected to the stores (3 to 6) which in turn feed a count comparator (7). The coder (2) also provides an initiate code to circuitry (11) which starts the processing. The signal from the count comparator (7) is output to the word store (8) so that an identified code is recognised by the address counter (9) controlling the film motor (19, 20) drive control units (21, 22). The keypad (1) also has reset (15) facility and continuous up or down stepping control (12, 13).

Title: Electric rail vehicle slip measuring system - is used to maintain max. adhesion between drive wheel and rail by correction of stator frequency
Inventor: HAHN KARL DIPL ING
IPC: B60L3/10
Filed: 1979-04-27
Abstract: The slip measuring system uses the control value for the torque regulation of the AC drive motor as an indication of normal acceleration, for controlling an integrator (5). The output of the latter determines the frequency (F1) supplied to the motor circuit, being an upwards corrected value of the stator frequency (F1). The integrator (5) also receives a signal which is a first order periodic differential of the difference between the required and actual torque, upon a drop in torque following the max, torque being exceded, for reducing the stator frequency (F1) to correct the slip.

Title: Extruder for thermoplastics - divider head before nozzle splits flow to specified formula to produce uniform thickness extrusion
Inventor: WINTER HORST HENNIG DR ING
IPC: B29C48/08
Filed: 1979-08-16
Abstract: An extruder tool for thermoplastics has a feed hole, a divider tool with hole and overspill gap, and nozzle. Similar flat strip flow cross-sections are in both the divider hole and overspill gap, the quotient of the square of the mean divider hole width and the cross-sectional area of the divider hole being between 4 and 10, at least around the divider hole inlet. Constant speed of emergence from the nozzle in azimuth direction (with tubing) or across the nozzle width (with flat extrusions) gives constant extrusion thickness and equal melt flow time regardless of position at nozzle of throughput or polymer used. The critical shear speed is not exceeded.

Title: Plug connector for medium and high voltage cables - has plug at end of crimp-fit sleeve having inner copper layer and outer steel layer
Inventor: GOEHLICH LOTHAR ING GRAD
IPC: H01R4/20
Filed: 1979-09-20
Abstract: The connector has a plug (20) at one end and a crimp-fit sleeve (21) at the other. The crimp sleeve has two or more layers to ensure that the outer diameter of the sleeve is also less than the diameter of the wire or conductor being connected. The inner layer (22) is made of copper or aluminium and acts as current conductor whilst one outer layer (23) is made of steel and ensures that the inner layer maintains contact with the wire after crimping. The combination of plug and crimp sleeve reduces the work involved in attaching the plug to the cable's wire or conductor. The connector couples cables to cable fittings simplifying the amount of work required in connecting such fittings.

Title: Telephone subscriber station - has standard two wire link to analogue exchange plant and optional bidirectional digital speech processor
Inventor: STREHL HERBERT DIPL ING
IPC: H04Q11/04
Filed: 1980-02-29
Abstract: In order to provide the subscriber of a standard speech channel telephone terminal having traditional two-wire link to the analogue exchange station (A-Vst) with the option to communicate also with digital stations, the circuit associates the four-wire microphone (M) and audio transducer (H) terminals with the usual analogue gating circuit (AG) for transference to the two-wire line (NSW-Al) and, furthermore, with changeover switches (U2, UM, UH) responsive to a control voltage level (u) which when switched applies the four terminal wires to another, digital, gating circuit (D2V) comprising a speech encoder circuit (CO) and digital transmitter (DS) on the one hand, and a speech decoder circuit (DEC) and digital receiver (DE) on the other hand. To avoid mutual interference of the incoming and outgoing digit signals the two channels are allocated different time slots, or differently weighted frequency ranges. Normally the telephone set may be connected via the analogue 2 to 4 line gating circuit (AG). Upon detection of a high-bit rate signal, a control voltage (u) is generated which automatically switches to the digital/analogue gating and processor unit (D2V). Alternatively, a change-over switch (BU) may be used.
Patent DE-3014499-A1 (DE)
Title: Conductor rail clamping mechanism - uses spring loaded jaw against one edge, having stepped clamping surface with alternative specified contours
Inventor: KOHL LUDWIG ING GRAD
IPC: F16B2/12
Filed: 1980-04-16
Abstract: The method of securing a conductor rail in a piece of electrical equipment such as switchgear, indicating appts. etc., uses a top hat section rail which is fitted into a recess in another member, and secured by a spring loaded sliding clamping jaw (26). This jaw locks against one side of the rail and the other side fits into a side recess. The jaw has a sloping serrated surface, terminating in a rounded rose which fits under the edge of the projecting flange of the rail. The slope of this surface is not more than 10 degrees for positive locking. In one form,the jaw has a plain port (27) sloping at this small angle, followed by a stepped surface (28) which can slope at a large angle. In alternative desings, these surfaces can be convex or concave. In another form, the plain part is below the stepped part, and the stepped part is steeper.
Patent DE-3014974-A1 (DE)
Title: Ribbed heat exchanger tubes with smooth ends - mfd. continuously by drawing through a split ribbed and a smooth die
Inventor: OPPERMANN WILLI-F
IPC: B21C37/20
Filed: 1980-04-18
Abstract: Heat exchanger tubes with longitudinal ribs are produced continuously on a tube welding and drawing plant in which at least two drawing dies are arranged. One which has the inner contour to suit the tube profile (e.g. an octagonal star) is split into at least four segments. The other has a smooth bore of the same diameter as the tops of the ribs and can be used to produce sections with a smooth dia. A measuring device senses the smooth sections so that flying shears can produce a cut in the middle of them. The presence of smooth ends facilitates the assembly of ribbed tubes in heat exchangers by welding.
Patent DE-3017663-A1 (DE)
Title: Shut=off spindle support - with three sets of spring washers for impact absorption during emergency operation
Inventor: HECL JAROSLAV
IPC: G21C13/06
Filed: 1980-05-08
Abstract: The spindle head with spindle for the quick-acting shut-off element in the emergency cooling system of a nuclear power station rests on a support head with a threaded hub at the bottom and an internal shoulder on the periphery. A nut on the hub thread urges the support head against a support casing through a set of spring wasbers. Dowels prevent any angular displacement between support head and support casing. This allows some space for dilatation and absorbs the impact of a sudden shut-off. The load is equally distributed over three sets of spring washers.

Title: Photo-tomographic X=ray system - has adjustable collimator grid to minimise X=ray scatter
Inventor: BUCHMANN FRANZ DR RER NAT
IPC: A61B6/02
Filed: 1980-06-21
Abstract: The fast exposure tomographic X-ray system has an efficient adjustable collimator grid above the photographic film which ensures that there is no blurring of the image caused by x-ray scatter. Several x-ray sources (2a-c) all in one plane (1) send x-ray beams which cross over within the patient (5) and, after passing through an anti-scatter collimator grid (10), illuminate a photographic film (8). The collimator (10) is a plate shaped grid with parallel segments (11) and is curved so that the segments are aligned with the x-ray beam. Provision is made for adjusting the curvature to take into account variations in the patient-film distance.

Title: Quenching tank for hardening workpieces - which rest on grate suspended in duct through which quenching liq. is circulated to ensure uniform quenching
Inventor: KUEHN FRIEDHELM DIPL ING DR IN
IPC: C21D1/64
Filed: 1980-07-19
Abstract: In one corner of the tank is a propeller which stirs the quenching liq.; and at a distance from the propeller is a vertical duct immersed in the liq. The duct has an upper zone with a constant cross-section, and a bottom inlet zone which curves outwards to facilitate the entry of the liq. The workpieces are placed on a grate which is lowered into the duct. The space between the base of the tank and the bottom inlet zone of the duct is large w.r.t the vertical length of the inlet zone of the duct; whereas the propeller is near the surface of the liq. The duct is pref. located in a horizontal partition in the tank so the liq. is compelled to flow up the duct. Uniform quenching is achieved irrespective of the position of the workpieces on the grate.

Title: Doser for adding casting powder to continuous casting moulds - where powder is conveyed by gas through doser, and extra gas stream is used to shield doser from heat rising from mould
Inventor: SCHREWE HANS ING GRAD
IPC: B22D11/108
Filed: 1980-11-24
Abstract: This is an addn. to 2814496, which describes a dosing hopper fitted with a gas inlet pipe so a stream of gas carries the casting powder into the mould. The novelty in the present invention is that the gas distribution chamber located on the base of the hopper below an intermediate base permeable to gas is divided into a front chamber and a rear chamber, each with an inlet pipe for gas. This addn. describes protection of the front chamber from heat arising from the mould so the front chamber has a longer working life. The components forming the front chamber are pref. replaceable.
Patent DE-3045610-A1 (DE)
Title: Speed control for electric hand drill - uses triac mounted on heat sink in motor cooling air path
Inventor: MEYER GARY D
IPC: H02K23/66
Filed: 1980-12-03
Abstract: The driving motor supply is regulated by a triac whose gating signal is controlled by the finger operated trigger switch of the drill. The triac is mounted on a heat sink and the whole assembly placed in the inlet air duct to the motor cooling fan. Using the intensive cooling thus provided the triac can be operated safely at full motor current demand continuously. The trigger switch can therefore be employed as a gate signal controller only without any current making or breaking duty. This greatly eases the duty on the switch and also eliminages electrical disturbance when the switch makes or breaks current. The triac can also be used as a simple on-off switch without providing speed control.
Patent DE-3048056-A1 (DE)

A resorption heat pump comprising an ejector (10) and a rectification column (14), from which working medium vapour is fed to a resorber (12), and also comprising a circuit (19, 20) which connects the resorber to a degasifier (11) and in which the concentrated solution of working medium flows from the resorber to the degasifier and a depleted solution flows back to the resorber, also comprising an absorber (13) connected to the ejector by a circuit (26, 27) in which the working medium evaporated in the degasifier and fed via a line (25) is absorbed and returned to the separator, characterised in that the branch of the circuit (20) for the depleted working medium solution between the degasifier (11) and the resorber (12) contains a branch line (32) leading to the ejector (10) and to the rectification column (14), and a control valve (30), the reflux of depleted solution to the resorber and to the ejector and the rectification column being controllable by means of the control valve in dependence on the resorber pressure.
Patent DE-3049416-A1 (DE)
Title: Heat pump with open air circuit - has externally driven compressor and second compressor driven by expanding air from heat pump
Inventor: RICHTER HORST
IPC: F25B9/00
Filed: 1980-12-30
Abstract: The heat pump air is compressed as nearly as possible adiabatically, after which its heat is transferred by isobaric cooling in a heat exchanger to a heat transfer medium. The cooled air is then used to perform mechanical work as it is expanded adiabatically to atmospheric pressure, leaving the circuit at a temperature lower than the intake one. Air compression takes place in two independent compressors, connected in parallel. Only the smaller part of the air for the circuit is compressed in an externally-driven compressor, while the remainder is compressed in a compressor driven by expansion of the previously compressed air.
Patent DE-3102921-A1 (DE)
Title: Window or door
IPC: E06B3/263
Filed: 1981-01-29
Abstract: The application treats a window or door consisting of a supporting frame, of a holding frame mounted on the latter via frame-connecting elements and of a multi-pane insulating glass which is held by these two frames and the weight of which is absorbed by the supporting frame and which bears respectively with its edge, a pane seal being interposed, against a longitudinal strip of the supporting frame and a longitudinal strip of the holding frame. The following features are primarily considered to be new:   a) the holding frame is mounted on the supporting frame via the frame-connecting elements so as to be displaceable perpendicularly to the frame plane; b) the two pane seals form a vapour-tight closure over the entire pane circumference; c) there is arranged between the two frames a frame-sealing profile which bridges the displacement gap between the two frames, has an elasticity, expansion fold or the like permitting or compensating the displacement and closes off the air gap between the two glass panes relative to the outside atmosphere in a vapour-tight manner over the entire frame circumference.
Patent DE-3103870-A1 (DE)
Title: Laminate core for transformers or the like consisting of blocks
Inventor: WAASNER BRUNO
IPC: H01F27/245
Filed: 1981-02-05
Abstract: Such a laminate core exists which is composed of blocks (1, 2) of which one is in each case inserted between two of the others which hold the interposed block between them. In this case it is desirable to simplify not only the production of the means which are required to hold the blocks on one another but also the joining together of the blocks. This is achieved in that each of the two ends of each joined-together block (1) engages by means of a cornice-like latching tab (8) in a corresponding latching recess (10) in the retaining block (2), in its longitudinal direction, fitting into a lateral recess (7) in the associated retaining block (2), the laminate parts (4) of the joined-together blocks (1) running in the plane of the laminate parts (4) of the retaining blocks (2). The laminates are firmly held together without any U-shaped parts, and the means which hold the blocks together are produced by stamping the laminate parts.   <IMAGE>
