Patent DE-3122194-A1 (DE)
Title: Two-layer material
Inventor: DOETSCH HANS-PETER
IPC: B32B7/027
Filed: 1981-06-04
Abstract: Two-layer materials in the form of bimetal are known per se. By the joining together of two layers of materials with different coefficents of thermal expansion, bimetal strips assume different curvatures with changing temperatures and can thus be used as a temperature-dependent closed-loop or open-loop control element. However, the possible uses of bimetal are relatively restricted because of its other properties. Accordingly, the inventor has sought other two-layer materials which can be used for similar applications but with a greater scope. He has developed two-layer materials in which at least one layer consists of plastic and the other consists of a non-metallic material with a coefficient of thermal expansion which is as different as possible. In this case the two layers must have a high modulus of elasticity. The expansion coefficient of one layer must be zero or approximately zero, whereas the other layer has a high expansion coefficient. At least one of the layers must additionally have a shape-memory capacity. It has been found, surprisingly, that two-layer materials of this kind, in particular those with incorporated carbon fibres, have extremely good properties in the desired direction, so that they open up a multiplicity of fields of application which are closed to bimetallic closed-loop or open-loop control elements. <IMAGE>

Title: Device for the floating transmission of DC voltage signals
Inventor: SCHNEIDER RUEDIGER
IPC: H04L25/20
Filed: 1981-09-17
Abstract: The arrangement for the floating transmission of DC voltage signals operates with a constant-current source formed from a transistor (T1), a zener diode (Z1) and bias resistors (R1, R2, R3). This constant-current source charges a capacitor (C1) which is in turn discharged via a trigger diode (D1) to a transformer. As a result of the constant charging current of the capacitor, the circuit becomes highly insensitive to interference voltages (disturbance voltages) at the input. <IMAGE>

Title: Device for collecting transport trolleys, in particular shopping trolleys
Inventor: WANZL RUDOLF
IPC: A47F10/04
Filed: 1983-01-29
Abstract: In order that transport trolleys or shopping trolleys do not stand around in a disorderly manner in the car parks of self-service shops, coin deposit systems have been developed, which make possible chaining the transport trolleys to a fixed point by means of coin-operated locks and connectors. In previously known collecting devices, it is not possible to move a stack of transport trolleys in a manner which protects the coin-operated locks and connectors, as the stack has to be pulled. The invention therefore proposes a device (1) for collecting transport trolleys, in particular shopping trolleys, which has a trolley guide (9) with a connector (4) for coupling a first transport trolley (2) and in which there is provided, on an uproght post (12), a crosspiece (13) which is orientated transversely to the movement direction of the transport trolleys (2) and which between itself and an opposite wall (8) forms a free space (16) which is suitable both for pushing transport trolleys (2) through and for walking through. <IMAGE>

Title: Method for amplitude limitation, and a controlled limiter circuit
Inventor: BESSLING BERT
IPC: H03G7/00
Filed: 1983-03-12
Abstract: A method for signal limitation when predefined voltage levels are exceeded and a controlled limiter circuit, in particular for limiting the AF signal voltage fed from a microphone to a downstream amplifier in the event of overload, where the amplifier is used simultaneously as a limiter (level controller) and, if the voltage level is exceeded, is activated by an actuator with an exponential characteristic to define the control depth. At the amplifier output, a window discriminator detects when the AF signal voltage supplied by the microphone exceeds the level and, during the period of excess, a downstream timer is activated which feeds a time-proportional activation signal to the actuator.
Patent DE-3311345-A1 (DE)
Title: Process for maintaining constant wall thickness during extrusion (production) of elongated objects of thermoplastics, such as films, pipes, tubes, cable sheaths, sheets and profiles, and measuring and control device for extruders, extrusion pressers or the like for elongated objects
Inventor: PANDER PETER DIPL ING
IPC: B29C48/92
Filed: 1983-03-29
Abstract: The invention relates to a process for producing elongated objects from thermoplastics having constant lateral profile, for example films, tubes or the like, by extrusion or extrusion pressing. In the process the weight per metre (kp/m) is determined from the weight of the thermoplastics fed especially in individual charges to the extruder or the extrusion press and from the length of the object produced. The average absolute thickness of the object, calculated taking into account the width, is compared with the average, relative thickness of the object, which is determined from several measurements of the thickness taken over the width of the object. The error calculated from this comparison is used as a correction factor for determining the absolute value for the thickness of the thinnest point. The thickness control of the object in the longitudinal direction is carried out after the thickness profile with the absolute value of the thickness for the thinnest point has been shifted to the lower permissible tolerance limit. With a measurement and control process of this kind it is possible to produce an area unit of the object with a minimum of material consumption whilst complying with the lower permissible tolerance limit, without measurement devices matched to the respective material being required.

Patent DE-3316019-A1 (DE)
Title: Rotor, especially of a rotary-wing aircraft
Inventor: HAHN MICHAEL DIPL ING
IPC: B64C27/33
Filed: 1983-05-03
Abstract: The rotor of a rotary-wing aircraft has one or more rotor hub arms (2.1), which point radially outwards, for the connection of in each case one rotor blade (1) which has a blade neck section (1.2), which is torsionally soft for the blade incidence angle movements, between the blade root (1.1) and the blade itself (1.3). In this case, the blade incidence angle control takes place via a torsionally-stiff sleeve (5) which extends along the blade neck section (1.2) without making contact and has a relatively soft-bending construction. In order to be able to dismantle this blade control sleeve (5) without detaching the blade connection, said sleeve is assembled from an (on the blade root side) inner part (5.1) and an (on the side of the blade itself) outer part (5.2), and only the outer part is soft in bending as a profile which can be displaced with respect to the blade neck section (1.2). <IMAGE>
Patent DE-3316755-A1 (DE)
Title: Dividing head
Inventor: DITZEL HEINZ
IPC: B23B31/26
Filed: 1983-05-07
Abstract: The invention relates to a dividing head for clamping tools. According to a feature of the invention, the clamping device for securing the head of a tool holder is actuated by means of a hydraulic device which, besides centring the tool holder, also effects, as a result of the tensile forces that are exerted, a smooth bearing of the tool holder on the front face of the dividing head. The hydraulic devices of this dividing head are also enhanced by the fact that it is made possible to feed a liquid through the head piece and the clamping piece of the dividing head to the tool itself. Separate channels in the dividing head allow the regions of the clamping piece provided to accommodate and adjust the tool holder to be blown out with compressed air and thereby be cleaned before using the tool holder. <IMAGE>
