Title: Adjusting device, especially for a microwave oven time switch
Inventor: MEISNER ALFRED
IPC: H01H43/04
Filed: 1985-10-12
Abstract: In the case of an adjusting device, especially for a microwave oven time switch, an adjusting element 7 which can rotate is coupled to a drive (gear mechanism) 3, 4, 5 whose step-up ratio changes as a function of the rotation angle of the adjusting element 7. A friction wheel 8 is provided in order to maintain an essentially constant torque on the adjusting element 7, despite the different step-up ratio. A friction spring 17, which is supported on an actuating element 12, rests against said friction wheel 8. The actuating element 12 is displaced as a function of the rotation angle of the adjusting element 7 so that the friction torque on the friction wheel 8 is greater when the step-up ratio of the drive 3, 4, 5 is relatively low than when the step-up ratio is relatively large. <IMAGE>

Title: Electron beam deflection system for a magnetically deflecting oscilloscope tube
Inventor: PALATA JAROMIR DIPL ING
IPC: H03K4/69
Filed: 1985-12-13
Abstract: The electron beam deflection system for a magnetically deflecting oscilloscope tube has applied to it operating voltages which are positive (+UB) and negative (-UB) with respect to a reference potential (E). The deflection system has an amplifier (1) which has a signal input (3), a signal output (5), a positive supply input (7) and a negative supply input (9). The negative supply input (9) is connected via a first parallel circuit, consisting of a first diode (11), on the one hand, and consisting of a series circuit, comprising a first capacitor (13) with a first switch (15), on the other hand, to the negative operating voltage (-UB). The positive supply input (7) of the amplifier (1) is connected in an analogous manner via a second parallel circuit, consisting of a second diode (19), on the one hand, and of a series circuit comprising a second capacitor (21) with a second switch (23), on the other hand, to the positive operating voltage (+UB).

Title: Method for improving the washing effect of washing agents by the evacuation of the textile-containing vessel before the start of the washing operation
Inventor: HEYES JOSEF DR PHIL
IPC: D06F35/00
Filed: 1986-03-10
Abstract: The invention relates to a method for improving the washing effect of washing liquors, characterised in that the vessel containing the laundry is filled, before the start of the washing operation, with a gas which can readily dissolve in the water of the washing liquor, the air present in the pores of the fabric being exchanged with this as a result of diffusion. Because the gas present in the vessel occurs in excess, in practice the air present in the pores will be displaced completely when the washing operation starts. The washing liquor can then fill the pores, because the gas present in the pores is absorbed by the water of the washing liquor.

Title: Method and circuit arrangement for testing access right to signal processing system
Inventor: WURZENBERGER JOHANN FRANZ
IPC: H04L29/06
Filed: 1986-03-11
Abstract: To test the right of access to a signal processing system (SVS) from peripheral devices (TE, BS) which are connected to it and designed for supplying signals, and if required also receiving them, it is intended that for every peripheral device in the signal processing system, a keyword is stored. Such a keyword is derived in each case from a code number which is assigned to the respective peripheral device, and from identification information which can be freely selected for the particular peripheral device. On an intentional access from one of the peripheral devices, the code number which it outputs and the associated identification information are then first linked to the keyword which is assigned to the relevant peripheral device. <IMAGE>

Title: Charger for nickel-cadmium cells
Inventor: HAUSER KARL-HEINZ
IPC: H02J7/00
Filed: 1986-08-06
Abstract: The invention relates to a charger for nickel-cadmium cells, which charger has a constant-current source for the charging current. According to the invention, a peak detector (7) in conjunction with a trigger circuit or comparator circuit (8) is used for disconnecting and terminating the charging process, both the output of the peak detector (7) and the cell voltage value being applied to the input of the trigger circuit. In the event of a voltage difference between the two inputs, the trigger circuit switches and the charging process is terminated by disconnection logic 10. The invention is based on the knowledge that the cell voltage passes through a maximum which corresponds to the maximum capacity. The position of the cell voltage maximum is dependent on the previous history of the nickel-cadmium cell to be charged and is determined on each occasion by the circuit according to the invention, for disconnection. <IMAGE>

Patent DE-3635345-A1 (DE)
Inventor: GOESSLER GERHARD DIPL ING
IPC: H05B3/74
Filed: 1986-10-17
Abstract: A radiant heater has a shallow shell-like support for carrying heating resistors and a glass ceramic top plate. A connection and hot warning indicating device is arranged in the space between the top plate and the support. The light source is preferably a low voltage tungsten halogen lamp which projects, at most, slightly beyond the front side of the support. Despite a very compact construction, the radiant heater is not subject to dazzle effects even over a large area, and a readily visible indicating illumination is obtained. The light source can be operated at different brightness levels, for example one brightness level indicating the switched-on condition of the heating resistor and the other brightness level indicating the hot-to-touch condition of the top plate, notwithstanding the switched-on or switched-off condition of the heating resistor.

Title: Target marking for an observation device with additional illumination
Inventor: BLUMENTRITT MARTIN
IPC: G02B27/32
Filed: 1986-12-03
Abstract: In the creation of a target marking for a laser beam (4) in an observation device (21), it is desirable to be independent of the reflective properties of the object observed. This can be achieved by outcoupling a part of the light of an additional illumination (15) for surrounding-field illumination of the point of incidence (1) of the laser beam (4) by means of a mirror arrangement (3). The outcoupled light is reflected on a target mark (5) and, after coupling into the beam path of the observation device, generates in the image plane of the latter the target mark image. Advantageously, the mirror arrangement (3) consists of a splitter plate with a reflection-reducing layer (22) on the upper side and a reflection-increasing layer (23) on the lower side. The invention can be used in all devices, in which a marking of the point of incidence (1) of a laser beam (4) in the observation field (2) of an observation device is desired. <IMAGE>

Title: Haymaking machine
Inventor: LESSLHUMER JOSEF
IPC: A01D84/00
Filed: 1987-02-06
Abstract: The rake tines used in conventional haymaking machines strike the stalk crop violently and thereby lead to considerable crop losses. The rake tines match the ground profile only inadequately, consequently take up loose earth from earth mounds etc., and thus lead to fodder contamination. These disadvantages are to be avoided. To avoid these disadvantages, the machine has at least one device (1, 7, 19) with air nozzles (19) directed onto the crop. The new haymaking machine is suitable for the largely crop-loss-free and contamination-free turning, tedding, broadcasting, swathing, swathe division, etc., of hay with an especially intensive loosening effect. <IMAGE>

Title: Inertia switch
Inventor: FALMBIGL AUGUST
IPC: H01H35/14
Filed: 1987-03-30
Abstract: When the movable switching contact (3) is in the position of rest in the installed state of the inertia switch, the fixed breaking contact (2) of the inertia switch surrounds the said switching contact in the upper region with essentially the same distance on all sides, the switching contact (3) being suspended in the breaking contact (2) in such a manner that it is electrically insulated from the latter and is acted upon by a holding force (F) on the side opposite the suspension. This holding force (F) can be applied by means of a spring (9) or a loading weight (13) and - just like the distance between the two interacting contacts (2, 3) - can also be adjustable, making it possible for different triggering conditions to be set. <IMAGE>

Title: Method and device for manufacturing cushion elements by back-foaming the covering material
Inventor: KOENTGES GERHARD
IPC: B29C44/14
Filed: 1987-05-08
Abstract: The method and the device for manufacturing cushion elements by back-foaming the covering material work with a stretching frame (2), by which the covering material is pressed onto the lower part (1) of the mould in order to guide the covering material into the mould cavity (3) on sucking in. In order to ensure that the covering material is guided as uniformly as possible during the suction movement and thus to avoid in particular the formation of undesirable folds, pressure-medium-actuated stretching cylinders (8) are provided, which press the stretching frame with an adjustable pressure force in the direction of the covering material (10). As a result, the force, which has an influence on the movement of the covering material during suction, is correspondingly uniform over the circumference of the stretching frame. In addition, pressure-medium-actuated lifting cylinders (12) can be provided, which lift the stretching frame against the pressure force of the stretching cylinders in order to ensure, in particular towards the end of the suction movement, that the covering material moves into all the corners of the mould cavity and lies smoothly against the walls of the mould cavity (Fig. 1). <IMAGE>

Title: Polycrystalline ceramic material and process for the manufacture thereof
Inventor: YECKLEY RUSSEL L
IPC: C04B35/593
Filed: 1987-09-11
Abstract: The flexural strength of hot isostatically pressed (HIPped) silicon nitride containing between 1 and 12% by weight of rare earth oxide and not more than 0.5% by weight of aluminium oxide is substantially increased by treating green bodies in flowing nitrogen at a temperature between 1000 and 1500@C prior to degassing for hot isostatic pressing. The iron content of the bodies is likewise reduced by this heat treatment and it is assumed that sources (flaws) responsible for fractures are also eliminated thereby. Silicon nitride bodies having a flexural strength above 525 MPa at 1370@C can be manufactured in this way.

Title: Method and apparatus for applying layers of high-temperature superconducting material to substrates
Inventor: GUNZELMANN KARL-HEINZ DIPL ING
IPC: C23C4/11
Filed: 1988-02-26
Abstract: The application of HTSC material to workpieces can be effected by thermal spraying of ceramic powders having superconducting properties as the starting material onto substrates of any shape required, a continuous covering layer thus being applicable. Hitherto, the coated workpieces then had to be sintered under an oxygen atmosphere in order to regenerate the superconducting properties. According to the invention, an oxygen heat treatment of the substrate is carried out at the same time as the spraying, to which end the spraying of the particles is carried out under an oxygen atmosphere and the substrate is brought, at least by the spray jet, to a temperature > 600@C. To this end, there is present, as the accompanying apparatus, a large-volume chamber (60) into which the spray appliance (10, 20), the substrate (1) and further aids for carrying out the coating process under an oxygen atmosphere can be introduced. <IMAGE>
