Title: Actuating device for mixer batteries for cold and hot water
Inventor: OTTELLI GIORDANO
IPC: F16K31/53
Filed: 1988-06-21
Abstract: The invention relates to an actuating device for controlling mixer batteries for cold and hot water, having two valves 17, 18 inserted in parallel for dispensing hot and cold water. The valves 17, 18 are both provided directly with an external toothing 24, 25 or with externally toothed sleeves 26, 27 and are actuated with the aid of an operating handle 22. An inner ring 28 provided in the operating handle 22 is provided with two toothed arcs 29, 30 which are arranged at a circumferential spacing and interact alternately with the toothing 24, 25 of one of the valve spindles 17', 18' while an inward-pointing hub 23 provided with a toothed arc 31 likewise interacts alternately with the toothing 24, 25 of one or the other valve spindle 17', 18' in order, by means of different rotations of the operating handle 22, to bring about the dispensing of cold, hot or mixed water and the closure of the mixer battery. <IMAGE>

Title: Kinking protection device for cable plugs
Inventor: REICHLE HANS
IPC: H01R13/56
Filed: 1988-06-22
Abstract: In the case of the kinking protection device for a cable plug, the cable (5) is passed through a hinged piece (2) which consists of plates (3) which follow one another at a distance, preferably in each case have a relatively small circumference and are connected at least approximately centrally by means of flexible web means (4), the edges (6) (which are closed when the cable (5) is bent in at least one direction) of the plates (3) being fitted with snap-closure means (7, 8) which act in pairs and engage in one another in a retaining manner, but preferably such that they are detachable, if a predetermined kinking angle is exceeded. If the predetermined kinking angle is exceeded here, the snap-closure means become effective and hold the cable emerging from the plug in this angular position even when the force which causes the bending of the cable is removed. This prevents fatigue fractures on the cable as a result of continuous alternating bending. <IMAGE>

Title: Method of production for a Bi-CMOS element using grooves (slots)
Inventor: AHN HYEONG KEUN
IPC: H01L29/423
Filed: 1988-12-30
Abstract: A method of production for a Bi-CMOS element using grooves is described, using which it is possible to produce a bipolar element and CMOS element simultaneously on a substrate by grooving or isolating etching. In the method, an oxide layer is grown, an enclosed N<+> layer is formed, an epitaxial layer of the n-type is grown after removing the oxide layer, another oxide layer is grown, a multiplicity of insulation regions is formed, by allowing a boron impurity to diffuse in, the base, collector, emitter and drain regions are formed, the grooves are formed after the oxide layer has been removed, an oxide layer is grown after inversion of the epitaxial layer, the electrode window is opened and a metal, such as, for example, aluminium, is deposited, in order thus to provide a connection for the electrode terminals of the base, of the emitter and of the collector of the bipolar element as well as the drain, source and gate electrodes of the CMOS element.
Patent DE-3904921-A1 (DE)
Title: Laminated iron core, especially for transformers with mutually interleaved sheet-metal laminates
Inventor: GEGENFURTNER HELMUTH DIPL ING
IPC: H01F27/245
Filed: 1989-02-17
Abstract: Such iron cores (10) are normally composed of mutually interleaved stacks of sheet-metal laminates (11-16), the sheet-metal laminates (11-16) formed by n sheet-metal layers overlapping in a stepped shape in one direction at the abutment points (17) of the limbs and/or of the yokes. According to the invention, the n sheet-metal layers - with sheet-metal laminates (11-16) overlapping in the form of steps in each case by the same extent at the abutment points (17) of the limbs and/or of the yokes - are divided into two groups and are taken alternately from one group and the other during the layering. Iron cores formed in layers according to the invention enclose relatively large rubbing surfaces (friction surfaces) between adjacent sheet-metal layers at the abutment points (17) of the limbs and/or of the yokes, so that reliable overlapping with low magnetisation reversal losses at the same time is ensured even in the case of large manufacturing tolerances. <IMAGE>
Patent DE-3908509-A1 (DE)
Title: Method of MAG welding
Inventor: DANZER WOLFGANG DR
IPC: B23K35/30
Filed: 1989-03-15
Abstract: In MAG (metal active gas) welding, slag is formed on the surface of the welding seam, which slag tends to flake off and leads to problems in corrosion resistance. To avoid these problems, it is proposed that in welding use is made of a welding rod (electrode wire) containing the additives carbon, copper, manganese, silicon and titanium in the following amounts:     Carbon: from 0.07 to 0.14% by weight,   Copper: less than 0.30% by weight,   Manganese: from 1.30 to 1.60% by weight,   Silicon: from 0.70 to 1.00% by weight,   Titanium: from 0.05 to 0.10% by weight. In this way there is formed a skin of slag distributed uniformly over the welding seam, which skin adheres firmly to the welding seam.

Title: Discharge fitting for sinks or the like
Inventor: WEIDNER EUGEN
IPC: E03C1/22
Filed: 1989-04-08
Abstract: The present invention relates to a discharge fitting for sinks, which is characterised in that it exhibits at least two discharge valves (10, 16) which are located one beside the other, are each assigned to a bowl of the sink and are connected by at least one connecting pipe (18), discharge valves and connecting pipes each being assembled by plug-in or latching connections to form a structural unit. The discharge fitting according to the invention has the advantage that the entire fitting can be pre-assembled as a structural unit and fastening of the fitting on the sink by the fitter is thus considerably facilitated. Preferably, the connecting pipes (18, 28) can be displaced axially with respect to one another, with the result that the necessary distance between two discharge valves (10, 16) located one beside the other can be adjusted. <IMAGE>

Title: Process for the production of roving bobbins
Inventor: SCHOENFELDER HANS-JUERGEN DIPL
IPC: D01H1/04
Filed: 1989-06-26
Abstract: The invention relates to a process for the production of roving bobbins for automatic ring-spinning machines and refers to the sector of roving production. The use of the invention is aimed at providing a process for the production of roving bobbins, in which the roving is prevented from being damaged or torn when roving bobbins are used for the automatic roving-bobbin changing process. The object upon which the invention is based is, for the automatic roving-bobbin change on the ring-spinning machine, to develop a process for the production of roving bobbins, by means of which optimum take-up conditions under extreme mechanical roving stresses are guaranteed on the roving bobbin. According to the invention, this has been achieved by means of a process which varies the roving twists within a roving-bobbin winding, in that the number of roving layers and the increased flyer speed are optimised by means of counters and controllers known per se in a microcomputer, in such a way that the roving acquires an increased twist of 10-30% over a specific number of roving layers. <IMAGE>

Inventor: HOLZINGER OTTO DR
IPC: H02J13/00
Filed: 1989-08-24
Abstract: A process is disclosed for transmitting data in data processing systems having distributed signal processing machines that intercommunicate via a serial data bus and that exchange messages with each other.
