Title: Automatic testing device for telecommunications devices
Inventor: UECK MARTIN
IPC: G01R31/28
Filed: 1984-10-12
Abstract: The testing of telecommunications devices directly at the location where they are used was hitherto possible only by means of very large test devices, was very time-consuming and could be carried out only by specially trained telecommunications engineers. It was totally impossible to test simultaneously a multiplicity of telecommunications devices in this way, with the resulting highly disadvantageous consequences for the breadth of communications actually required from the telecommunications devices. In order to be able to test the telecommunications devices (11) directly at the location where they are used under real working conditions on the one hand, and to enable testing by untrained operators on the other hand, so that bulk testing of the telecommunications devices (11) is possible, the invention proposes an automatic test device (10) for telecommunications devices, in particular radio devices comprising transceivers, in which an externally controllable radio measuring device arrangement (12) is used in conjunction with an operating unit (15) which has at least one input keyboard (16), a display device (17) and a printer device (18) and which is connected to a computer (14), forming a control unit (13) which is connected via a line (19) to the externally controllable radio measuring device arrangement (12) and the telecommunications device (11) to be tested. <IMAGE>

Title: Process and device for dissolving a bitumen-in-water emulsion
Inventor: BIALEK RENE FRANCOIS
IPC: B01F13/10
Filed: 1984-12-21
Abstract: A process and device for preparing an oil-in-water emulsion, namely a bitumen-in-water emulsion, by premixing the same for a sufficiently long time so that the emulsion is fully mixed with emulsion-breaking diluents and further additives. The modified bitumen-containing emulsion stream is circulated through a premixer. At least part of the emulsion stream is recycled therein with simultaneous mixing with fresh emulsion. The now thoroughly mixed emulsion is then in a state in which it is more suitable for introduction into a separator in which separation of the water from the bitumen takes place.

Title: Circuit arrangement for a half-controlled electronic branch pair
Inventor: JACOB CHRISTIAN DR ING
IPC: H03K17/08
Filed: 1985-01-22
Abstract: For half-controlled electronic branch pairs, a circuit is specified which enables inductive (current-impressing) currents to be commutated with a predetermined pulse frequency to two different potentials with the aim of controlling the current and voltage variation in, for example, direct-current pulse controllers, link-circuit converters and direct converters. In this arrangement, the powers which have hitherto been produced in the electronic branch pairs during the switching-over process are reduced to such a level that relieving circuits can be minimised or can be omitted. The basic and/or parasitic inductances responsible for the production of the power losses from the direct-voltage circuit in which such a branch pair is arranged are blocked by a parallel capacitor (Cp) which is connected in parallel with the branch pair (ZP) directly and with low inductance. <IMAGE>

Patent DE-3512488-A1 (DE)
Title: Device for dividing deep-frozen foodstuffs, especially fish
Inventor: NIENSTEDT HEINZ
IPC: A23G9/28
Filed: 1985-04-06
Abstract: The invention relates to a device for dividing deep-frozen foodstuffs, especially fish, which take the form of rectangular blocks, into a multiplicity of rectangular rods. The device comprises a circular saw which is arranged above an enclosed table top (1), individual circular saw blades (5) being clamped between spacer discs (6) on the shaft of the said saw. The circular saw blades (5) have a diameter which is large in relation to the thickness of the blocks. The reinforcing spacer discs (6) clamp the circular saw blades (5) up to an outside edge region which corresponds to the thickness of the block. As a result of these measures, relatively thin circular saw blades of sufficient rigidity can be used. This means a small amount of cutting work is required and that the amount of material removed is kept small. The material removed is not lost as far as the final product is concerned, however, as it remains above the enclosed table, is collected by a pressure roller (9) arranged downstream and is transferred to the top of the block. <IMAGE>
Patent DE-3519200-A1 (DE)
Title: Thread regulator for threads of a textile machine oscillating in their longitudinal direction
Inventor: JOST GUNTER
IPC: D03D51/28
Filed: 1985-05-29
Abstract: The invention relates to a thread regulator for threads oscillating in their longitudinal direction in a textile machine. The invention can be used, for example, for regulating the pile warp threads in a double carpet-weaving machine or in a warp-knitting machine. The aim of recognising faults in the thread run of a thread set moving to and fro at an early stage and in a reliable manner is served by the object of monitoring thread breaks and thread tighteners in a thread set moving to and fro by means of the same thread regulator. According to the invention, each thread carries a thread dropper displaceable on the latter. The stroke of each thread dropper is limited in both directions of the thread run by thread-guide plates. The spacing of the thread-guide plates is greater than the length of the thread dropper, so that a passage, in which a light barrier is located, can be formed in the region of each of the two stroke ends of each thread dropper. The two light barriers are arranged parallel one behind the other in the direction of the thread run and perpendicularly to the thread set.
Patent DE-3521882-A1 (DE)
Title: Metering slide valve control
Inventor: WELLE ROBERT
IPC: F02M59/24
Filed: 1985-06-19
Abstract: This method of control is especially suitable for electric pumps, which require a compact construction. The lift can be kept shorter compared to bevel edge control, which in turn permits a cam shape closer to the ideal. The control edge is straight and the end of injection thereby sharply defined. The friction occurring in the control is less than in pumps which are controlled by rotation of the plunger. The adjusting pin keeps the slide valve self-locking in position. The force expended by the governor is small and free control with little delay is possible. The control components are of simple design and owing to the method of control the pump can be made from fewer moving parts than pumps known to me.
Patent DE-3522656-A1 (DE)
Title: Production of coin blanks
Inventor: WALTHER HANS MICHAEL DIPL ING
IPC: A44C21/00
Filed: 1985-06-25
Abstract: For the production of coin blanks for relatively high-value coins, a process is proposed, according to which blanks are fabricated from a gold-coloured strip-type copper-based material and then electrolytically gold-plated on all sides. Such coins have the advantage over gold-plated nickel-based materials that the gold hue of the surface tends more towards red instead of towards grey, that the gold hue can be more readily maintained in mass production and that there is virtually no noticeable wear of the gold plating.

Title: Method of controlling hydrostatically driven duplex plunger pumps and hydrostatically driven duplex plunger pump
Inventor: OBERMANN KLAUS
IPC: F04B9/105
Filed: 1985-10-02
Abstract: Each plunger piston is coupled to a double-acting hydraulic piston/cylinder unit, the action upon which with hydraulic medium is controlled by means of hydraulic control members in such a manner that their pistons in each case carry out stroke movements in opposite directions. The hydraulic control members are actuated by electric control signals developed depending upon the position of the plunger piston. During operation, the stroke of the plunger pistons is measured continuously and the individual and/or overall quantity flow delivered in each case by the plunger piston is calculated. The calculated quantity flows are then continuously compared with one another and/or a desired quantity flow with a given delivery characteristic and, if appropriate, calculated deviations of the quantity flows are developed to form control signals, with which the hydraulic control members are driven with a view to a correction of the action upon the piston/cylinder units.

Title: Warning device for monitoring the function of an air dryer, in particular in pneumatic brake systems of motor vehicles
Inventor: BREFKA KLAUS DIPL ING
IPC: B60T17/00
Filed: 1986-02-07
Abstract: In a compressed-air reservoir (1) which is fed from an air compressor with an air-drying device in between, a hollow screw (3) can be fastened to the underside in a sealed manner. A bore (11) accommodating a pin (5) passes centrally through the hollow screw (3). The pin (5) is displaceable in the bore (11) in a sealed manner and projects with a head (15) into the interior of the compressed-air reservoir (1). A pellet (7) of water-soluble material is inserted between the head (15) of the pin (5) and the end face of the hollow screw (3) extending into the interior of the compressed-air reservoir. If the pellet (7) comes into contact with water in the compressed-air reservoir as a result of an inadequate function of the air dryer attached to the compressed-air reservoir, it dissolves in such a way that the pin (5) is displaced outwards as a result of the action of the pressure in the compressed-air reservoir. In this way, a part of the pin extends so far out of the hollow screw (3) that there is an optical indication for the accumulation of moisture in the interior of the compressed-air reservoir and thus for the inadequate function of the air dryer. The pin (5) can also be used as a contact element for an electric switching device which is used for optical or acoustic indication in the cab of the vehicle. <IMAGE>

Title: Rotary piston pump, in particular discharge gear pump
Inventor: FITJER AXEL DIPL ING
IPC: F04C2/08
Filed: 1986-05-10
Abstract: A discharge gear pump for discharging a corrosive polymer melt under great mechanical loading is described. The problem lies in the material pairing in the area of the bearing bushes mounted in the side plates of the pump housing and of the drive shaft made of corrosion-proof steel. In order to avoid the mechanical wear on the shaft, co-running armour bushes are arranged between the bearing bushes and the drive shaft. The toothed wheel and the armour bushes arranged on both sides on the drive shaft are made either as one part or from a number of components, and in particular from a sintered material which is corrosion-resistant and after its hardening has an adequate hardness of more than 58 HRC.
