Title: Apparatus for the electrical discharge machining of workpiece surfaces
Inventor: INOUE KIYOSHI
IPC: B23H7/38
Filed: 1982-04-20
Abstract: The invention relates to an improved electrical discharge machining method including the apparatus, as a result of which the efficiency of the machining can be considerably increased. Within the scope of the invention, this can be achieved by the provision of a multiplicity of ultrasonic funnel arrangements (8) which act at preset positions on the surface of the tool arrangement (4, 5, E). The electromechanical transducers (81) of the various ultrasonic funnel arrangements (8) are here individually excited, as a result of which mechanical vibration shocks are emitted from the emission surfaces (8a) of the corresponding amplifier horns (82) to the tool arrangement (4, 5, E). These mechanical vibration shocks are fed in this way to the machining surface of the machining electrode (E), as a result of which preselected areas are set in vibration. The multiplicity of vibration shocks produced at various points of the tool arrangement (4, 5, E) are combined sequentially or simultaneously so that the machining surface of the electrode (E) is uniformly set in vibration over the entire surface. The arrangement can preferably be used with a multiplicity of electrodes (E) which can be of relatively large design. Furthermore, deep, narrow and/or complicated hollow spaces (C) can be produced in this way inside workpieces (W). <IMAGE>

Patent DE-3236367-A1 (DE)
Inventor: WALTER HEINRICH
IPC: B61L25/02
Filed: 1982-10-01
Abstract: The invention relates to a device for train location and track-free signalling in the field of an electronic actuator, the actuating groups of which contain microcomputers and are connected to one another via geographic data lines arranged according to the route of the track. Axle counter results acquired at counting points arranged between the actuating elements are passed on along the set routes from actuating group to actuating group. The track-free signalling and the train location occur, using the microcomputer of the actuating groups, by comparing the axle counts registered at the individual counting points. If the distances between the individual counting points are stored, the speed of the vehicles can be determined by means of a real-time determination of the passage of the first axles of the vehicles.

Title: Multi-coloured painting instrument
Inventor: STRAHL GERHARD
IPC: B44D3/22
Filed: 1983-01-27
Abstract: In a pressure-tight vessel, about 6 interior chambers with a capacity of about one litre each are arranged on the inner wall of the main vessel in such a manner that a space of about 1l remains in the centre of the main vessel, and this in turn is subdivided into individual chambers for the storage and cleaning of painting instruments, etc. The main vessel is provided with a twist lid or claw-closure lid. Fitted in the centre of the lid is a valve which accepts inert gas cartridges for generating a superatmospheric pressure in the main vessel. The 6 interior chambers contain liquid ink which, under the superatmospheric pressure, is pressed outwards through elastic hoses into painting pens. Built into the tips of the painting pens are ball-valves which allow the ink to emerge under manual contact pressure onto the painting surface. The painting pens can be provided with attachments for coating or roller-coating the inks. In addition to the ball-valve in the painting pens, other manual or automatic valves can also be built into the painting pens. Substantial advantages can be achieved through the immediate, alternating, long-term application of various liquid inks without it being necessary for the ink containers to be opened or closed or for the painting instruments to be cleaned. The attachment of paint rollers, paint brushes, etc. to the painting pens makes it possible to carry out overhead work, since the ink emerges under gas pressure. Also the possibility...

IPC: B60R22/20
Filed: 1983-11-23
Abstract: In a device for adjusting the height of the upper fastening or deflecting fitting for the shoulder belt of a safety-belt system, especially in motor vehicles, having a means for the preferably automatic adaptation of the height of the fastening or deflecting fitting to the sitting position of the person to be strapped in, a device arranged additionally to the fitting sensing the position of the belt band relative to a parameter of its operative connection to the strapped-in person and triggering a reaction to the state determined, there is the problem that, because of the direct coupling of the detection of state and the signal emission, the height-adjusting device directly follows all the movements of the strapped-in person. To achieve the object, whereby the readjustment of the deflecting fitting is to take place only in the event of a lasting change in the sitting position of the vehicle occupant, a means for comparing the actual value determined relative to the selected parameter with the fixed desired value is proposed, the reaction being triggered when a predetermined deviation between the desired value and actual value is continuously exceeded. <IMAGE>

Patent DE-3407858-A1 (DE)
Title: Electrical vacuum switch
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/12
Filed: 1984-02-29
Abstract: In the case of vacuum switches, especially for high continuous and short-circuit currents, the following problems, inter alia, exist:   a) switching element heating in the vacuum and heat dissipation from the vacuum,   b) electrodynamic repulsion of the switching elements,   c) high contact pressure - contact welding - particle formation,   d) high contact pressure - increased drive energy.   The following design measures are used to solve these problems: Outer switching elements (25, 27) are arranged parallel to the inner switching elements (6, 7) of the vacuum switch housing (15), in order to relieve the stress on the said inner switching elements (6, 7). At the same time, a special coupling device (30, 31, 33, 36) ensures that the inner switching elements always close first during switching on and that the outer switching elements always open first during switching off. In the switched-off state, the insulating space between the outer switching elements has at least the same dielectric strength as the insulating space between the inner switching elements, which enables mutually independent switching element stroke movements. As a result of these measures according to the invention, the vacuum switch becomes a completely conventional switch, but having excellent switching properties. <IMAGE>

Title: Heat-insulating facade cladding
Inventor: LEIFELD GISBERT TH
IPC: E04F13/02
Filed: 1984-03-16
Abstract: In order to increase the insulating effect with respect to insulating plasters, while at the same time avoiding disadvantages such as those which occur with respect to the durability of the external plaster in the case of complete insulation with insulating panels, mineral-fibre panels are arranged and fastened in such a way that they cover 70 to 95 %, preferably 80 to 90 %, of the structural surface to be insulated. The uniform distribution of the uncovered structural surfaces, which are jointed with insulating plaster and do not fall below the thickness of the mineral-fibre panels in one of their dimensions, can be achieved by laying insulating panels of up to 0.6 m<2> in size, at a sufficient distance from one another in each case. A fabric mat can be arranged between an additionally applied insulating-plaster layer and the mineral external plaster. In order to facilitate operations, the insulating panels can butt directly against one another with parts which have been cut or punched out, the overall surface area of the cutouts amounting to 5 to 30 %.
