Title: Telephone subscriber's appts. circuit - includes logic with current control for coil of monostable relay
Inventor: LOHR JOACHIM
IPC: H04M1/31
Filed: 1980-04-23
Abstract: The more conventional bistable relay is replaced by a monostable design to save on current demand. The monostable is backed up by current control circuits which permit a large transient current to ensure that the relay picks up. After this, the current is regulated down to the min. value at which the relay will hold in. A reservoir capacitor provides a source of energy when the current is interrupted due to dialling. The relay is only energised during the dialling period. Backing up the power supply is a current control circuit. This ensures that a constant current supply is available for the logic circuits in the telephone set. It operates with an imaging circuit which acts to keep the load current as an image of the current in the reference branch of the circuit.

Title: Spin resonance spectra detonator system - uses decoupling signal pulse groups in async. relation to signal scanning
Inventor: ERNST RICHARD R PROF DR
IPC: G01R33/46
Filed: 1980-07-07
Abstract: The spins of one nuclear type of a specimen, located in a magnetic field, are energised by pulsed h.f. signals. The relaxation oscillations of the spin are repeatedly scanned in preset time intervals and recorded. A h.f. decoupling signal is applied to the specimen, in order to reduce a coupling with spins of other nuclear types. The signal consists of a periodical train of pulse groups, each containing at least one pulse. The pulses of a group are rated to provide together a rotation of the spin movements by n x 360 deg., n being an integral number or zero. The pulses are so short that their frequency spectrum, based on Fourier analysis, covers, the entire resonance region of the other nuclear type. The pulse groups of the decoupling signals are asynchronous in relation to the signal scanning.

Title: Vehicle trailer brake master cylinder - uses air from brake supply tube to push down pistons to open wheel cylinder supply valves
Inventor: SULZYC GEORG
IPC: B60T8/18
Filed: 1980-08-26
Abstract: The trailer brake valve is for dual brake circuits. The compressed air is passed via the supply tube through the valve and on to the valve supply chambers. When the brakes are operated pressure from the brake tube forces the control piston downwards closing the connector valve and opening the brake supply valve to supply pressure to the wheel brake cylinder. The lower piston is also pushed down to work similarly to allow pressure to pass to the brake cylinder. When the brake is released the control piston cylinder is evacuated in the normal way allowing the pistons to rise and close the supply valves.
Patent DE-3032911-A1 (DE)
Title: Speech encoding unit - has store containing n-bit long digital information as code values
Inventor: ZLOF DIETER
IPC: H04K1/02
Filed: 1980-09-01
Abstract: The encoding unit consists of a storage medium (5) from which continuing n-bit long digital values are extracted. In this way, a voltage curve is formed which represents a mixture of different amplitude values of undefined frequencies which can be designated as a type of 'white noise'. This curve (63) is applied simultaneously to the speaker-side difference stage (I) (30) and the listener-side difference stage II (60). The so called 'information curve' (65) appears likewise at the difference stage (30) via the microphone (31) in the form of a voltage curve. By subtracting the voltages of both curves, a new curve, - a 'difference curve', - is obtained. The code curve (63) is applied to a modulator (40) whose output is reconverted to a sound signal transmitted via the telephone (70). This sound is reconverted to a voltage and a mixed signal produced fed to a demodulator (50). The difference curve (64) is then fed to a difference stage (60) from where the original information curve containing the speech information, is converted to sound via the earpiece (61).
Patent DE-3033129-A1 (DE)
Title: Duplicated controls safety feature - requires a special key for engagement and dual operation
Inventor: HANDEL HUBERT
IPC: F16K35/06
Filed: 1980-09-03
Abstract: Mechanical components of a control, such as handwheels for oil circuit valves, in nuclear power stations are often duplicated, with the second set of controls to be operated outside the control room. To prevent unauthorised manipulation, the handwheel is normally kept clear of the operating spindle. Its operation requires the use of a special key to retract a pin so that the handwheel can be pushed forward to engage the valve spindle. This makes it impossible to manipulate the controls without possession of a special key.

IPC: B01D47/10
Filed: 1980-12-20
Abstract: Very fine dust contg. a considerable amt. of soluble salt is sepd. in a wet washer with two separate venturi sections. The first is a high-speed section of cascade type with a series of washing rings peripherally attached to the cylindrical wall, and central apertures. The second venturi is a low-speed section for agglomerating the mist formed in the first section, and supplying fresh water to compensate for preceding losses. Low concn. liq. from this section may be sprayed into the head of the cascade section. For removing particles down to below one micron from exhaust gases, which cannot be cleaned effectively in wet cooling towers because of poor wettability and solubility losses. Suitable also for hygroscopic dusts which clog filters. Water from the outer edges of the washing rings is constantly returned to the active central zone, and high relative speeds between air and water assist in binding the dust.

Title: Display device for cardboard packages, books, photo albums, games or the like
Inventor: HEINRICH MATTHIAS
IPC: A47F7/14
Filed: 1981-02-07
Abstract: In the known display devices, the abovementioned articles are placed on the shelf like books, with the back or the narrow-side packaging towards the customer, in which case no uniform picture can be achieved with this display as a result of the different sizes. An additional factor is that the narrow side of the product has small writing on it and is not readily recognised by the customer. The subject matter of the invention is a display device in shelf form, in which inserts for the products offered are mounted on a shelf wall, wherein a pull-out shelf which is infinitely variably extensible is arranged on the base of the shelf wall, wherein a tiered insert can be hung on the shelf wall by hanging means above the pull-out shelf, wherein one or more angular shelves are vertically adjustable by hanging means above the stepped insert, and wherein a stepped insert can be hung by hanging means above the angular shelves in such a way that the tiers with the product packages are inclined forwards. It is thus achieved that as many packages as possible of very different sizes can be accommodated in a very small space on a shelf in a clearly visible manner. The invention is most clearly illustrated by Figure 5. <IMAGE>

Patent DE-3121523-A1 (DE)
Title: Securities with originality features in the form of luminescent substances, method and device for determining originality
Inventor: KAULE WITTICH DIPL PHYS DR
IPC: G06K19/14
Filed: 1981-05-29
Abstract: The securities have luminescent originality characteristics in a narrow band which can only be excited in essentially the same narrow wavelength range in which they also emit. In the case of these originality characteristics, the originality signal is therefore superimposed and concealed by the test signal which is stronger by several orders of magnitude. Consequently, the originality of the securities cannot be established using the usual methods and devices for detecting the luminescence. The test device used utilises the decay properties of the luminescence emission for its detection. The originality characteristics can be applied to the paper fabric, the printing inks used, also to mixed fibres or safety threads.
Patent DE-3122364-A1 (DE)
Title: Differential hang-glider
Inventor: STEINER GEROLF DR
IPC: B64C31/06
Filed: 1981-06-05
Abstract: In hang-glider flight, suitably shaped and adjusted flying bodies obtain lift from an approximately horizontal air flow. Energy for the incident-flow speed required comes:     1. in the case of free-flying gliders from their descents 2. in the case of tethered gliders from the wind speed over the ground 3. in the case of differential hang-glider flight from tethering the glider to a towing body by means of a glider line; the incidnet-flow speed then effective for the drive results from the difference between the wind speed of the towing body being towed along and of the total double combination. In this case, the towing body can be braked on the ground, in water or in lower, more slowly flowing layers of air. In the last-mentioned case, the towing body can also act as a kite-like flying body. The heading can be influenced to a degree by lateral shifting of one or both partners, the altitude by appropriate vertical displacement. Such devices can be used manned or unmanned for sport, transport or imparting messages (e.g. advertising, propaganda). d

Filed: 1981-06-10
Abstract: The electric output signal of a pulse generator coupled to a shaft is frequency-transformed into a frequency-proportional voltage which is then smoothed. It is thus possible to obtain a highly accurate value of actual speed in conjunction with a low smoothing time constant. Preferred applications of the invention are position-controlled speed drives having subordinate speed control. <IMAGE>
Patent DE-3123843-A1 (DE)
Title: Flap valve
Inventor: GRUNER KARL
IPC: F16K1/228
Filed: 1981-06-16
Abstract: The invention relates to a flap valve, the valve flap of which, which can be pivoted by means of a flap spindle, can be pressed by its sealing edge against the seat surface of a flap housing. After being pivoted into a stop position, said flap executes a further, raising (lifting) movement into its closing position. According to the invention, the high closing forces which occur, which depend on the size of the seat and the pressure difference, are eliminated by relieving the valve flap as far as possible of the pressure acting against it.

Patent DE-3130944-A1 (DE)
Title: Contact and extinguishing device for electrical switching apparatuses
Inventor: FLOHR PETER
IPC: H01H71/52
Filed: 1981-08-05
Abstract: In the case of an electrical automatic switch of small format, an arc-splitter stack is located alongside the electromagnetic tripping device, which arc-splitter stack is bridged at the end, in each case on an extension of its two arc guide plates, by means of a pivoting contact which can be operated by sides of the snap-action mechanism. In this case, one guide plate at the same time forms the stationary contact and the magnet yoke of the electromagnetic trip device, while the other guide plate is at the same time constructed for insulated support of the pivoting contact, for retention of the electrothermal tripping device and for connection to one of the connecting terminals. In order to make it possible for the arc column to run quickly from the contact interruption point into the arc-splitter stack, the pivoting contact element (which is formed from a sheet-metal strip of U-shaped cross-section) is provided shortly above the support point, on its lateral web, with a run-off tongue which is bent in a projecting manner and from which the base of the arc is magnetically blown (as a result of the field concentration occurring here) onto an inclined ramp which is formed by the adjacent guide plate. <IMAGE>
