Patent DE-3121173-A1 (DE)
Title: Circuit for a phase-gating controller
Inventor: BICHLER HELMUT DIPL ING
IPC: H02M1/08
Filed: 1981-05-27
Abstract: The invention relates to such a phase-gating controller, which is suitable, for example, for controlling a triac and is provided, as normal, with a sawtooth-wayform generator (which is triggered on the basis of the zero position of the mains power supply AC voltage) and with a comparator to which the sawtooth-wayform generator is applied on the one hand and an external control voltage is applied on the other hand. The construction according to the invention of such a circuit is intended to be improved in comparison with normal circuits of this type with respect to its susceptibility to defects (interference). In addition, the circuit is intended to manage without the otherwise normal monoflop (monostable multivibrator) and the cost (complexity) linked with this application for capacitors and resistors which are difficult to integrate. For this purpose, according to the invention, a digital logic circuit is provided between the comparator and the signal output of the circuit, which digital logic circuit additionally controls the sawtooth-wayform generator. In addition, the control voltage which acts on the comparator is also connected to a further circuit part, which jointly controls the sawtooth-wayform generator with a pulse former. This circuit part is created in such a manner that, as a result of its influence on the sawtooth-wayform generator, the sawtooth-wayform signals supplied by said generator are provided with edges which form in a constant manner with time. Finally, the control of the sawtooth-wayform generator by the logic circuit is created in such a manner that the lower level of the sawtooth-wayform signals supplied to the comparator are maintained constant until reception of the respectively successive control pulses supplied by the pulse transmitter to the sawtooth-wayform generator.

Title: Suction nozzle for use in dust-extraction systems
Inventor: LANGE HORST DIPL ING
IPC: B08B5/04
Filed: 1981-06-30
Abstract: The invention relates to a suction nozzle for use in dust-extraction systems, consisting essentially of a nozzle box which starts from a pipe-connection fitting and terminates in a rectangular nozzle opening. To obtain a better suction effect, in particular an increase in the depth effect, the clear cross-section of the nozzle opening (3) is reduced, by means of profiles or longitudinal webs (5) inserted into the opening, to the cross-section of three narrow longitudinal slits (6a, 6b, 6c). <IMAGE>

Title: Incandescent bodies for electric lamps, using emissive materials
Inventor: AFFONSO GEB GRIGOLEIT
IPC: H01K1/02
Filed: 1981-07-20
Abstract: The invention relates to incandescent bodies for electric lamps, the filament of the lamps at the same time heating a nonmetallic, emissive material which does not have electric current flowing through it. The emissive material consists of oxides of the rare earths thorium oxide, with additions of cerium oxide. The light output ratio of the lamp is thus increased.
Patent DE-3137419-A1 (DE)
Title: Proportionally operating valve for fluid media
Inventor: LEUTNER VOLKMAR DIPL ING
IPC: F15B13/042
Filed: 1981-09-19
Abstract: A hydraulic proportional valve (10) is proposed whose DC magnet (13) is driven (in order to reduce hysteresis) with a jittered signal whose amplitude is regulated and which is superimposed on the basic signal. The position signal from a movement sensor (14) is entered into a bandpass filter (29) which is tuned to the frequency of an oscillator (22) and whose rectified output signal controls, in a limiter circuit (24), the amplitude of the jittered signal so that said amplitude becomes smaller as the fed back signal becomes larger. Despite the level of the friction force fluctuating, the amplitude can be limited to a level which reliably overcomes the stiction (static friction) and is insensitive to interference. <IMAGE>
Patent DE-3138835-A1 (DE)
Inventor: KOETZSCH HANS-JOACHIM DIPL CHE
IPC: C07F7/18
Filed: 1981-09-30
Abstract: The present invention relates to a method of preparing dimeric or polymeric organosilane esters whose ester component is at least one glycol moiety and whose silicon atoms are linked together by a glycol moiety. These compounds are known and are used as hydraulic fluids whose preparation involves considerable difficulty. The present invention avoids these difficulties by setting out from organosilane diglycol esters or triglycol esters and transposing them with diglycols or polyglycols. In this transposition the glycol ether corresponding to the glycols is formed and is removed by distillation. The degree of condensation of the organosilane ester products depends on the weight-ratio of the organosilane glycol ester to the diglycols or polyglycols.

Title: Planimetric game with a plurality of playing areas and fitting shaped parts for occupying the playing areas
Inventor: SCHWARZ JOACHIM DIPL ING
IPC: A63F9/10
Filed: 1982-03-02
Abstract: The game is for a plurality of people. It comprises a two-dimensional playing surface on which particular areas, the "playing areas", are marked (e.g. triangles, quadrilaterals, circles, polygons). It should be noted here that a plurality of playing areas must be present and that the shape of the individual playing areas can be different. Associated with the playing areas are "shaped parts" (e.g. triangles, quadrilaterals, circles, polygons) which are laid by the players on the playing area. The shaped parts are so designed that each shaped part fits, in terms of its size, on the playing areas but covers only a certain proportion of the latter. The shaped parts of the individual players must not differ in their respective sizes but must be differently marked (e.g. by colouring or hatching). To solve the problem, the outline of a playing surface is produced by drawing. A certain number of playing areas are denoted on the playing surface. By dividing a playing area into sub-areas of various sizes, shaped parts are defined which can then each cover a part of the playing area. By dividing all the playing areas as desired, the number of shaped parts is defined so that, at the end of the game, all the playing areas can be completely covered. In order to distribute the shaped parts in their respective sizes according to the number of players, the shaped parts determined on all playing areas are differently marked. <IMAGE>

Title: Vacuum chamber oven
Inventor: SCHMETZ PETER
IPC: F27B5/16
Filed: 1982-04-26
Abstract: The vacuum chamber oven for heat treating metallic workpieces contains, in a cylindrical steel housing (1), a heating chamber (2) having substantially rectangular contours, the walls of which have closable openings (17, 20) for the passage of a cooling gas, which can be circulated over a heat exchanger (24) with the aid of a blower (23). To be able to adapt the flow of cooling gas optimally to the particular batch structure and to achieve a uniform cooling rate within a batch, on the one hand a plurality of relatively small openings (17) or a larger opening are present in each case in two mutually opposite walls for alternately admitting gas into the heating chamber (2) for the purpose of creating gas flows in opposite directions, and on the other hand in the adjacent, identically oriented walls there is provided, at their edges, in each case a longitudinal gap (20) running parallel to the adjoining wall for discharging the gas, in which case the two longitudinal gaps (20) situated in different walls are to be opened and closed in each case at the same time as the admission openings (or the admission opening) in the wall on the opposite chamber side. As a result of this arrangement, during the cooling process the circulated cooling gas inside the heating chamber (2) can flow either vertically in two opposite directions or horizontally in two opposite directions. <IMAGE>

Title: Process for cartridging pulverulent explosives
Inventor: GREIFFENBERG HERBERT
IPC: F42B33/02
Filed: 1982-12-20
Abstract: In a process for cartridging pulverulent explosives on multi-spindle filling machines, the explosive is in each case, by means of, at each filling point, a driven internal spindle formed as a screw and an external spindle formed as a hollow spindle and driven in common with the internal spindle, taken along by the rotation of the internal spindle and the external spindle. When a preset filling quantity in a packaging jacket has been reached, the spindles are stopped. During cartridging, the spindles are driven in common via a gearbox. In order to maintain the cartridge weights and the density of the explosive filled into the cartridge with sufficient accuracy, it is provided that the speed of rotation of each individual combination of the internal and external spindle is separately varied, during running production, by means of small control gears.
