Patent DE-3437494-A1 (DE)
Title: Bimetallic fuse for corrosion indication
Inventor: GRUENAUER HEINZ
IPC: G01N17/00
Filed: 1984-10-12
Abstract: The invention relates to a device which indicates when a certain corrosion level is exceeded. In this arrangement, the difference in the standard potential (in accordance with the electrochemical series) upon contact between different metals and alloys is exploited. When this point of contact is subject to corrosive influences, so-called contact corrosion occurs. If a corresponding conductor made from two different metals or alloys is passed through by an electric current, the contact corrosion of the less noble component causes an increase in the resistance of the conductor until the circuit is interrupted. From the rise in resistance and/or the interruption of the circuit, an electric or electronic indication can be obtained. The requirement for a connection zone which is as thin as possible is met by a friction-welded joint. The semi-finished product obtained by friction welding can be processed further to give foils of any desired thickness for the production of the conductor strips. <IMAGE>

Title: Fuel control device for an internal combustion engine
Inventor: HORADA OSAMU
IPC: F02M11/02
Filed: 1984-12-12
Abstract: A fuel control device for an internal combustion engine comprises a fuel feed device for controlling the fuel feed to the internal combustion engine, a first operating element, which is mechanically connected to the control device and thereby serves for controlling the fuel feed, a second operating element and a coupling which mechanically links the first and the second operating element in such a way that provision is made for either their joint or separate movement. A sensor determines the position of an accelerator pedal for the engine, controlled by an operator, and a control device responding to the sensor delivers an output as a function of the accelerator position sensed by this. A drive device, which causes the movement of the second operating element, responds to the output of the control device.

Title: Detector system for a computer tomograph
Inventor: FEIGT INGMAR DIPL PHYS DR
IPC: H01L31/0232
Filed: 1985-02-04
Abstract: In a detector system (10) for a computer tomograph in which ionising rays pass through the body (6) on coplanar beam paths, a scintillator (14), which has its emission in the range of the wavelength of violet light and which is associated with a photodiode as detector (12), is allocated to each beam path.

Title: Method for producing permanent magnets in the form of sectors of circular rings
Inventor: DOEGE GUENTER
IPC: H02K23/04
Filed: 1985-03-22
Abstract: In the case of a method for producing permanent magnets in the form of sectors of circular rings, the following steps are carried out: Two rectangular magnets of small height are aligned such that the north pole of one magnet points upwards and the north pole of the other magnet points downwards. The two magnets are in each case split by a vertical cut in such a manner that two of the mutually opposite edges of the one magnet are separated into a short section and a long section. This results in two trapezoids for each magnet, one trapezoid of the one magnet being joined to one trapezoid of the other magnet such that the short sections of the trapezoids and, at the same time, the long sections of the trapezoids are arranged adjacent to one another, and such that similar poles of the trapezoids are in each case provided in the plane surfaces of the magnets. As a result of this method, it is possible to produce permanent magnets in the form of sectors of circular rings in a manner which is simple in production-engineering terms and is at the same time cost-effective.

Patent DE-3513360-A1 (DE)
Title: Security membrane keyboard
Inventor: MEYERS PIERRE DIPL ING
IPC: G07C9/00
Filed: 1985-04-15
Abstract: A security membrane keyboard is presented. In the usual construction of membrane keyboards comprising base, lower contact membrane, spacing membrane, upper contact membrane and design membrane there is inserted above the upper contact membrane an additional sturdy metal foil with resilient properties. This has the effect that there cannot occur any permanent deformations, attributable to finger force, of the keyboard surface, which could divulge the code key to unauthorised persons. In addition, this sturdy metal foil lends the keyboard a high level of resistance to violent attacks, for example to attempts to scratch or cut it. The insertion of raised elements between the keyboard base and the lower contact membrane achieves the effect that, if pressure is applied from above, all the membrane layers can go down over wide areas with a large radius of curvature and that, at the same time, the lower contact membrane is deformed to enter into a clearance of the spacing membrane until contact is made. This effect has the result that, in spite of the sturdy metal foil used, the exertion of little force suffices to achieve a deformation until contact is made when a key is depressed. <IMAGE>

Title: Method for signal and data transmission for featurephone stations connected via a two-wire transmission channel
Inventor: SCHNEIDER ADOLF DIPL ING
IPC: H04M11/06
Filed: 1985-09-30
Abstract: The invention relates to a method for signal and data transmission for a featurephone station which is in each case connected via a two-wire transmission channel to a telephone system with display units, speech being transmitted in analog form and signals and data in digital form above the speech band. The object is to maximise the use of available transmission time through cyclic polling of the transmission channels in response to stimuli from the telephone stations. To achieve this, the individual stimuli are processed according to the length of the signals and data which are to be transmitted back and also according to priorities, in most cases directly if very short signal lengths are involved. The method according to the invention is essentially for use in telephones with a substantial number of subscriber services in key telephone systems. <IMAGE>
