Patent DE-3143006-A1 (DE)
Title: Pressure valve
Inventor: SILVANI BENEDETTO
IPC: F15B13/04
Filed: 1981-10-29
Abstract: In a pressure valve, one piston face is acted upon directly by the system pressure and the other piston end face via a nozzle, the space between the nozzle and the piston being connected to a control line. In this arrangement, the nozzle is inserted into the control line, which is shut off if the nozzle becomes loose. In this way, an unwanted pressure build-up is avoided.

Title: Radio transmitter with an electronic sampling circuit controlled by a pulse generator
Inventor: HAHN MICHAEL ING GRAD
IPC: H03C1/00
Filed: 1981-12-15
Abstract: A radio transmitter with an electronic sampling circuit controlled by a pulse generator is proposed in which a radio-frequency carrier generated with a modulated transmitter oscillator is sampled in low-spectral fashion. For this purpose, a first delay circuit (13), at whose output (31) an undelayed potential changeover occurs at the start of a pulse and a delayed potential changeover occurs at the end of a pulse, is connected to the pulse generator (10). At the start of a pulse, the first delay circuit activates a transmitter oscillator (37) which, in its steady or latched state, emits a specific potential (UB1) which activates a second delay circuit (57) which allows the transmitter output stage (40) of the radio transmitter to rise or fall slowly and in roughly linear fashion at the start and after the end of a sampling pulse (i). <IMAGE>

Title: Gas- and liquid-tight storage battery and method of producing it
Inventor: KILB MANFRED
IPC: H01M50/193
Filed: 1981-12-23
Abstract: In alkaline storage batteries, the diffusion of electrolyte along the metal surface of a terminal element connected to the negative electrode and the escape of traces of electrolyte at the outside of the storage battery housing can be suppressed by carrying out an additional bonding with an alkali-proof two-component adhesive in the sealing region. For this purpose, those surfaces of the sealing element mounted in the sealing region which come into contact with the terminal element can be coated with the alkali-proof two-component adhesive from the very outset. The sealing region may, however, also be coated afterwards all round in a sealed manner with alkali-proof two-component adhesive, advantageously two-component adhesive with such a low viscosity that it is able to penetrate the gaps and crevices left at the sealing point. The novel bonding can be applied to alkaline storage batteries with any type of housing design, for example at the sealing point of terminal elements fed through the housing wall, to sealed joints between housing parts and, preferably, if the housing lid is held by means of an annular sealed joint to the edge of the opening of the storage battery housing itself.

Title: Electronic balance with top-mounted pan
Inventor: KNOTHE ERICH ING GRAD
IPC: G01G21/23
Filed: 1982-02-18
Abstract: In an electronic balance having a weighing pan (3) which is located above the balance housing (1) and which is supported via a connection piece on a load sensor (6) arranged within the balance housing (1), the load sensor (6) being part of a low-displacement force-measuring system, a lower plate (7) is fastened to the balance housing (1) underneath the weighing pan (3) at a short distance from the latter. The lower plate (7) has in the centre a hole, through which the connection piece (4, 5) between the weighing pan (3) and load sensor (6) fits with slight lateral play. The lower plate (7) is so designed that a path with low flow resistance between the inner space and the outer space for air remains open between the lower plate and balance housing. As a result of this design, in high-definition balances, the weighing pan is better protected against lifting forces which result from air flows out of the housing when the inner space heats up to a greater extent than the outer space. <IMAGE>

Title: Bearing element in reinforced concrete slabs
Inventor: BUEHRER RUDOLF DIPL ING
IPC: E04F15/024
Filed: 1982-02-19
Abstract: For advantageous multi-directional force transmission, over the shortest path, to thin reinforced concrete elements, in particular thin-wall bodies of the order of 2 to 4 cm in thickness, bearing elements are cast integrally in the concrete element, said bearing elements having an approximately frustoconical connecting portion and an edge portion extending approximately in the surface direction of the concrete element and spaced from the supporting element. Furthermore, a base portion, which can have a bore for the passage of a supporting element, can be provided. The course, in particular, of the connecting portion is expediently adapted to the assigned course of the respective supporting element. Bearing elements of this type are suitable for concrete slabs which are to be firmly connected to another building member via a bolt connection, and also for concrete slabs which are to be laid on supporting elements. Slight length variations occurring in the slab plane in the case of wall panels, partitions, floor slabs and the like can thereby be accommodated. Sound insulation is possible by means of a coating of plastically-elastically deformable material between the bearing element and the assigned supporting element. <IMAGE>

Patent DE-3222565-A1 (DE)
Title: Method and arrangement for demodulation of a binary frequency-modulated signal
Inventor: BISCHOFF BERNHARD
IPC: H04L27/156
Filed: 1982-06-16
Abstract: A high-stability demodulator is to be produced at particularly low component cost. The clock frequency of a clock generator, amounting to a high integral multiple of the bit frequency, is counted with a second divider and evaluated once a specified counter reading has been attained; this counter reading corresponds to a frequency which lies between the two signal frequencies. The second divider is reset with each edge of the binary frequency-modulated signal and is stopped once the specified counter reading has been attained. The attainment or non-attainment of the specified counter reading is fed as a logical "high" or "low" to the data input of a data flip-flop and is transferred with each edge of the binary frequency-modulated signal to the output of the data flip-flop. A first divider divides the clock frequency of the clock generator down to the bit frequency and is reset with each edge of the output signal of the data flip-flop.

Title: Special device for facial treatment
Inventor: FRENKEL WALTER
IPC: A61H33/02
Filed: 1982-10-07
Abstract: To extend the application possibilities of the body-part treatment device proposed in the main application P3214335.4, this same device, specialised for facial treatment, is equipped with a respiratory air supply in the form of a concertina bellows (17) or a highly flexible fabric-type tube (18). Both have disposable mouthpieces (19) through which the user breathes in the respiratory air during the treatment procedure from the hole (14) in the base of the treatment bath (2). As in the device in the main application, the face immersed in the heated bath water is treated with vibrational movements and ozonised fine bubbles. The function of the ozone burning chamber (4), vibration-generating unit (5) and compressed air-generating unit (3) and the heating arrangement (not shown in the drawing) are controlled via a keyboard (20). To prevent uncontrolled ozone production, the latter is released via a micro switch (21) only when the treatment bath (2) is filled with water. The special device is used for the prevention and treatment of early sagging of tissue, for inflammations, suppurations, fungal infections, burn scars, acid burns, inter alia, in the facial area. Because it is possible to supply respiratory air continuously during treatment, this supply can be extended from 10 seconds, as previously, to several minutes as required medically. <IMAGE>

Title: Short-wave rotating antenna
Inventor: GEYER OTTOMAR DIPL ING
IPC: H01Q3/04
Filed: 1982-12-18
Abstract: In the case of a short-wave rotating antenna, the connection of the supply line (which is constructed as a double line) to the rotatable antenna is designed as such that the antenna can be rotated by the shortest possible route from any position to a new position while maintaining a reliable electrical connection, without the supply line being twisted by more than 90 DEG . This is achieved according to the invention by providing a rotary switch, which is arranged transversely with respect to the longitudinal axis of the tower shaft, for unlimited rotation of the antenna. This rotary switch has two stationary contact arms, which are arranged diametrically opposite one another, and two moving contact arms which are connected to the ends of the balanced supply line. In addition, this is achieved according to the invention by it being possible to at least compensate for the twisting (caught by the rotation of the antenna) of the supply line (which is clamped vertically in the tower shaft), by means of a suitable switching movement of the rotary switch. <IMAGE>

Title: Apparatus for the metered feed of concentrate into a diluent liquid
Inventor: LINDNER GUENTER
IPC: G05D11/02
Filed: 1983-05-09
Abstract: The apparatus is intended for a field sprayer arranged on a motor vehicle, with a controlled shut-off valve for a diluent and a concentrate metering pump arranged in the duct between the concentrate container and a feed valve. The metering pump, with a variable stroke, is driven by gearing with continuously variable transmission. The feed valve is arranged after the shut-off valve and is operatively connected to it such that uniform feeding of concentrate into the diluent and trouble-free operation are ensured. For this purpose, the shut-off valve, constructed as a diaphragm valve, is controlled in dependence on the quantity of concentrate passing through the feed valve. For the relief of the dynamic pressure formed above the diaphragm with the shut-off valve closed, a duct, closable by an outlet valve and connecting the retained liquid to the drain duct of the diluent, is provided. The outlet valve is operatively connected to the concentrate feed valve so that the passage for the relief of the dynamic pressure and hence for opening the shut-off valve is only released with the concentrate feed valve opened.
