Patent DE-3531316-A1 (DE)
Title: Power controller
Inventor: HERBST JOHANN
IPC: H01H37/12
Filed: 1985-09-02
Abstract: The power controller is used for the controllable supply of electrical power to a load, preferably to the heating element of a hot plate. It has a power circuit breaker, a bimetallic element which is heated as a function of the power being switched, and a manual adjusting device for selecting the power range. According to the invention, the control heating power is reduced in the upper power range and damaging excess temperature is hence prevented, in that the bimetallic heater consists of a resistor which is highly temperature-dependent and has a PTC characteristic. <IMAGE>

Title: Clamping device with wedge drive
Inventor: NERLING AXEL
IPC: B21B31/30
Filed: 1985-11-08
Abstract: Clamping device with wedge drive, in particular for clamping guide bushes in fittings for rolling, in which the setting wedge 3 prestresses Belleville springs 10 over an idle stroke before the part to be clamped is clamped by means of a rigid distance piece 6. It is therefore possible, when releasing the clamped connection, to bring about a state in which the part to be clamped is still under a spring force and, as a result, due to a certain "stiffness", can be adjusted more rapidly in the direction of adjustment. The mating wedge 2 is furthermore positively guided in the clamping direction. <IMAGE>

Patent DE-3546506-A1 (DE)
Title: Kitchen appliance driven by an electric motor
Inventor: HENNING HANS-JUERGEN
IPC: B26D7/24
Filed: 1985-09-09
Abstract: The kitchen appliance (1) driven by an electric motor comprises an input shaft (15) arranged in a housing (2) and an implement shaft (18) which can be brought into engagement with the input shaft (15) via a dog clutch (24). The implement shaft (18) serves to drive an implement (48) for processing food, this implement being rotationally fixed to the implement shaft (18). The implement shaft (18) is only connected in a fixed manner to the input shaft (15) in terms of rotation when, for the purpose of engaging the dog clutch (24), the implement shaft (18) is subjected by the implement (42, 48) to an axial displacement in its longitudinal direction counter to the force of a spring element (35). To avoid noise and wear during the engagement of the dog clutch (24), one or more teeth (32, 34) project in the axial direction on both sides of the clutch halves (17, 28). <IMAGE>

Title: Hearing aid to be worn in the ear
Inventor: WITTKOWSKI JOHANNES
IPC: H04R25/02
Filed: 1986-01-20
Abstract: Like many such hearing aids, this hearing aid exhibits a shell 1 individually adapted to the ear and accommodating the receiver 6, and a terminating plate 3 carrying the essential electric components and the asymmetrically arranged volume control 7. In addition to the shell and the terminating plate, a carrier 2 is provided on which the electric components are mounted or formed and the outside wall of which is circular. In the terminating plate 3, a correspondingly dimensioned circular opening for the detachable mechanical attachment of the carrier is provided. The microphone 9 is mounted directly and rigidly on the carrier 2, the microphone input 10 also being formed in the carrier and providing for short sound conduction. Due to the circular design of the outside wall and the opening in the terminating plate, the carrier can be arranged at different angular positions so that the asymmetrically arranged volume control is always easily accessible, taking into consideration the anatomy of the ear. A correspondingly designed and equipped carrier can be used for hearing aids for the left-hand and for the right-hand ear. The rigid and direct connection of the microphone to the carrier saves a lot of space. There is no acoustic feedback. <IMAGE>

Date Aug. 13, 1987.Cooling air flows over the inner wall of the blade, and emerges through small orifices provided in the blade jacket in the region of the boundary layer. The cooling air is admitted tangentially into an eddy tube provided with a closure and with a throttle in the region of the latter. The cooling air flow, which is cooled after flowing through the closure is fed into the blades and, after passing over the inner wall of the blade jacket, escapes from each blade in the region of the boundary layer. The heated air flow which escapes from the throttle is evacuated from the blade region. This airflow can be mixed with the cooling air or be introduced into the main gas flow.

Patent DE-3615108-A1 (DE)
Title: Differential pressure monitor, especially for liquid media
Inventor: DUNGS KARL
IPC: H01H35/34
Filed: 1986-05-03
Abstract: In the case of a differential pressure monitor, the measurement chambers (5, 6) to which the media (which are, in particular, liquid and whose pressures are to be compared with one another) are supplied are arranged on both sides of a common membrane (diaphragm) (4). The switching device (9), which is likewise arranged on one side of the membrane (4), is separated from the measurement chamber (6) by a wall (13). A transmission element which passes through this wall (13) and connects the membrane (4) to the switching device (9) is constructed as a bracket, the ends of whose limbs (21, 22) rest against the membrane (4) and a spring contact (10) of the switching device (9), and which bracket is supported in a hole (14) in the wall (13), in the region of its transverse web (29), by means of a collar (30) which is preferably elastomeric. There are no problems whatsoever involved with the support of the bracket in the region of its transverse web (29) and pivoting of the bracket, and hence transmission of the membrane position to the switching device (9), encounter no significant resistance due to the support, so that a differential pressure sensor having high sensitivity and low hysteresis, with a very simple construction, is available. <IMAGE>

Title: Device for fitting (populating) printed circuit boards
Inventor: WOLF ERNST DIPL ING
IPC: H05K13/04
Filed: 1986-05-31
Abstract: A device is described for fitting components to printed circuit boards, which device has a gripper system which can be positioned and has a cutting and bending tool which is arranged under the printed circuit board. According to the invention, the gripper system and the cutting and bending tool are detachably connected to one another by means of a U-shaped arm. In consequence, on the one hand the gripper system can pick the component which is to be fitted up, for example, from a magazine and, after picking the component up, can "tow" the cutting and bending tool to the position in which the component is inserted into the printed circuit board. In consequence, quick and accurate positioning of both tools is possible in one operation.
