Patent DE-2832223-A1 (DE)
Title: Miniature keyboard for telephone systems - has sprung contact plates, bent at several corners to form edges of different height
Inventor: KLEIN WOLFGANG
IPC: H01H13/12
Filed: 1978-07-20
Abstract: The contacts of the individual push-buttons are formed by a contact plate and by a circuit board contact rails, the circuit board extending under the entire keyboard. Contacting is carried out by a push-button operation forming a short circuit between two contact rails. An increased push-button stroke connects the short circuited rails with a further contact rail. The electric connection is controlled by tilting a sprung contact plate, which moves in the first stroke phase vertically to the push-button actuation, as in 2357887. The contact plates are angled at several corners to contact edges (71-74) of different height. The conductive tracks of the circuit board, metallised with wear-resistant material, form countercontacts.

Title: Segments contg. diamond grains bonded by sintered metal - where segments contain slots aiding the formation of sharp edges during sintering
Inventor: AHRENTSCHILDT ROLF-FRIEDRICH V
IPC: B23K1/20
Filed: 1978-12-06
Abstract: The segments are soldered or brazed onto a steel carrier core to mfr. slitting wheels, gang saws, reciprocating saws, grinding or milling tools, hollow drills or other tools or wear resistant objects. Each segment contains a slot which extends from the working surface through the segment to its diamond-free foot, or to the rear surface employed to solder the segment to the steel core. The slots mat possess different lengths, widths and depths according to the type of segment involved and its use; and are primarily used to improve the profiles of the cutting edges of the segment. The slots pref. also lead to side holes near the rear surface of the segment, so cooling water can flow through the slots. After sintering conventional segments, the edges of the latter are rounded and do not possess sharp corners. The slots (which are formed prior to sintering) result in sintered segments with improved profiles.
Patent DE-2901384-A1 (DE)
Title: Immiscible liquids contacting process - with rotor producing turbulent dispersions before phases can settle
Inventor: HAMILTON JOHN
IPC: B01D11/04
Filed: 1979-01-15
Abstract: Continuous contacting process useful e.g. in solvent extraction, passes the liquids in counterflow through a drum with a rotor. The rotor carries elements to produce a turbulent dispersion of one liquid in the other. Prior to their discharge, the liquids are allowed to settle in discrete phases. A stationary drum which can be slightly inclined against the horizontal is sealed by packings around a rotor shaft. Spacers locate intermediate discs which subdivide the drum into chambers. In the central part, buckets are arranged between the tie rods to create a turbulent dispersion. The two end sections, free from buckets allow the phases to settle. The turbulent dispersion maximises the extraction efficiency. The max. rotor speed can be increased without upsetting the rapid settling of the phases.

Title: Vehicle interior fresh air system - has automatic vent valve to isolate interior if outside air polluted
Inventor: BUHR HORST
IPC: B60H3/00
Filed: 1979-01-31
Abstract: A fresh air system for a motor vehicle has sensors in the air intake to monitor the incoming air for pollution. If the pollution exceeds a set level then the system dumps all the incoming air via a venting duct operated by a servo controlled flap valve. The entire system is operated by a central control for automatic operation. The incoming air can be deflected partially over a heat exchanger in response to temp. sensors and temp setting controls. The cump action valve provides a rapid response to outside pollution, such as when the car drives too close to the leading car and draws in exhaust fumes. The system operates fully automatically.

Title: Control system for diagnostic X=ray equipment - includes combined control of lighting intensity and image size for image amplifier
Inventor: SCHOEFER HANS DIPL PHYS
IPC: H05G1/64
Filed: 1979-07-11
Abstract: Diagnostic X-ray appts. includes a camera control system connected to a memory for data controlling the size of the image and also a lighting control system connected to a memory for data controlling the intensity of the lighting. These are interconnected with electronic control units for the image amplifier and the depth control screen. This forms an automatic control system so that the operator does not need to carry out adjustments to alter the image size immediately before operating the camera, for each different part to be examined. The lighting control and size control can be predetermined separately, and the size control can preferably be selected first. This can then be initiated by a suitable control button.

Title: Stabilised DC power supply generated from DC source - with self starting characteristics and without internal supply
Inventor: WEIGAND HEINO DIPL ING
IPC: G05F1/56
Filed: 1979-09-21
Abstract: The main switching transistor (2) controls the current in the primary winding (4) of a transformer whilst the secondary winding (5) feeds the output rectifier (6). The output (UA) is fed back through a regulator (7), opto-coupler (8) and pulse modulator (9) to control the switching of the main transistor. An initial start impulse is provided by a circuit connected to the high voltage input (10, 11, 14, 18, 21), and the pulse cut off at the required time by a level detector (29). The object of the dc to dc stabilised power supply circuit giving a step down in voltage is to eliminate the need for separate high voltage semiconductor components and separate transformers. Such components are often required for generating an auxiliary dc power supply for the control of the stabiliser.

Title: Colour TV tube shadow mask fixing - uses grooves or slots at screen edge for soldering or spring clip fixing
Inventor: ROTH ARNOLD ING GRAD
IPC: H01J29/86
Filed: 1979-09-29
Abstract: Inner corner and perimeter depressions of the TV tube, plus various grooves along edges are used to support the shadow mask by using spring clips, adhesive or sweated methods. The object is to simplify manufacture using one of several groove or slot designs described. The inner edge of the front screen glass (3) is grooved (2) where it is turned in (1) to form the side wall which is fixed (4,16) to the neck section (17) of the tube. The end edge of the neck section (17) may also be grooved (18) to correspond with the front screen groove (2). The shadow mask (10), with a sintered glass (11) to its metal side fixing (12), can be held in the groove (2,18) using a metal spring clip (15). Other methods available use glass solder to fix the metal support (12) to the front screen (1) at the front of the groove (2).

Title: IC engine cylinder compression evacuation - is from starter motor current alternating component integration and comparison
Inventor: MARINGER ALBERT ING GRAD
IPC: G01L23/08
Filed: 1979-10-11
Abstract: The method is for determining a measurement parameter value proportional to the compression of an internal combustion engine and involves measuring the alternating component of the electrical starter motor current. The conventional leakage correction approach is extended to maintain a final comparison value for individual cylinder compressions within defined limits. The current alternating component is integrated between successive minima. The integral of an individual cylinder is compared with that over an engine cycle and the result used to modify the value for the next cylinder. The improved value of the integral is then used as a compression reference. The ratio of the value following the smallest to the smallest integral value is tested. When it reaches a given value the integral value following the smallest is corrected by subtracting the product of the smallest integral value with the squared quotient of the tenth smallest integral value divided by the integral value over one cycle. The corresp. cylinder is subsequently omitted.
Patent DE-2950115-A1 (DE)
Title: Ion detector - using dynode to emit electrons for scintillator and photomultiplier
Inventor: STRADLING RODERICK SAFFIN
IPC: H01J49/02
Filed: 1979-12-13
Abstract: An ion detector with an input slit for an ion base includes a dynode assembly with one or more amplification stages. A potential, applied between the dynode and a scintillator or phosphorescence device generates an electrode beam at the dynode output, when the dynode receives an ion flow, and accelerates it towards the scintillator. Such a detector is less sensitive to vacuum faults than electron multipliers and has a stable amplifier gain. It also responds to negative ions.
