Patent DE-2455698-A1 (DE)
Title: Transmitter frequency adjustment testing device - which is used for AC telegraphy receives binary input signal with two valves and delivers FM output signal
Inventor: SCHULZ ALFRED
IPC: H04L27/12
Filed: 1974-11-25
Abstract: The signal two binary values are allocated to the sender two characteristic frequencies symmetrical relative to a centre frequency. It comprises a test signal (S1) generator (TG) which delivers a test signal instead of the input signal (S1). There is a test discriminator (MD) tuned to the f.m. sender signal (S2) centre frequency and delivering a demodulated signal (S3) whose instantaneous values depend on the difference between the sender signal (S2) and the centre frequency nominal value. There is an evaluation stage (AN) to which the demodulated signal (S3) is applied; it delivers a d.c. signal (S8) whose amplitude is displayed in a display device (AN1) as frequency error.

Title: Automatic drinking device for animals, esp. pigs - consists of tilted drinking-trough and water supplying pipe with valve
Inventor: ORBAN GEB LUKACS EUGENIA
IPC: A01K7/06
Filed: 1975-06-25
Abstract: The drinking trough is suspended so that it tilts by means of two eyes on pins. The pipe supplying water to the trough has, on its outflow piece, a valve which closes under the effect of water-pressure. An operating rod projecting into the tilt-path of the drinking trough opens the valve. The pipe also incorporates an emergency valve. A pig, wanting to drink, puts his head into the drinking trough and tilts it with his head. The wall of the trough presses the operating rod, thereby opening the valve. Water flows into the trough, as long as the pig is drinking. When he has finished, the trough tilts back to its original position, and the valve is closed by the water-pressure.

Title: Revolving ultraviolet and infrared lamps - allow uniform tanning with fewer radiation emitters with revolution by gear motor via angle rod assembly
IPC: A61N5/08
Filed: 1975-07-12
Abstract: The revolving lamps allow uniform intensity of irradiation. Only 4-6 emitters are needed to irradiate a surface for which 6, 9 or more emitters were required up till now, thus providing saving in current consumption. Also, the lower number of lamps and emitters and the small dimensions of the apparatus have an advantageous effect on the production costs. In an example, the lamps are rigidly connected to a threaded tube extending through a ball joint which is retained by two bearings bushes and bolted to the housing (D). The angle rod assembly (F) is movably attached to a cylindrical body (E) which is screwed onto the threaded tube. The gear motor (G) has an eccentric roller pin which engages in the push rod of the angle rod assembly.

Title: Storage tank roof plate installation - uses floating containers forming peripheral ring to raise plate by filling tank with water
Inventor: SCHROEDER HUGO DIPL ING
IPC: E04H7/06
Filed: 1975-10-07

Title: Formation of humus fertiliser from animal manure - using accelerated aerobic rotting with the addition of chemicals
Inventor: VOELSKOW PETER
IPC: C05F3/00
Filed: 1975-10-08
Abstract: Dry, friable fertilizer prodn. from biological wastes involves mixing the waste with other dry organic materials. The mixt. is then passed into a fermentation tower where it is subjected to an accelerated aerobic process under pressure and at an elevated temp. Anhydrous MgSO4 or quicklime is then mixed with the rotted material. This is then held for a period of 2-3 hrs. Finally the material is broken up. The control of gas throughput depends on the temp. reached in the fermenter. The rate of feed into the fermenter depends on the final humidity of the fermenter material. The pH value can be adjusted by addition of phosphoric acid or lime. Some undried rotted material can be added to the feed. Process is fast and safe and obviates use of toxic and dangerous chemicals.

Title: Acceleration detection circuit for vehicle braking systems - uses signals from antiskid control valves to charge capacitor with discharge during pressure release
Inventor: SCHULZ ALFRED DIPL ING
IPC: G01P15/00
Filed: 1975-12-24
Abstract: The acceleration detection circuit for anti-locking systems fitted to motor vehicles uses electrically-operated valves connected into the vehicle braking system. The valves are actuated by signals from the anti-locking control unit. the signal from the inlet valve is taken via an inverting transistor to the gate of an n-channel FET whose output feeds a further FET and capacitor charging circuit. The gate of the second FET is controlled by the signal to the brake system release valve. During the braking system pressure build-up the capacitor is charged up and is discharged during pressure release via the parallel-connected FET. The capacitor charge which is proportional to the braking force is detected and the amplified signal thus obtained is proportional to the acceleration of the vehicle.

Title: Helical aerial for UHF band - has coiled element of flattened rod with varying turns diameter
Inventor: ESPIRITO SANTO ABREU JOAO DO
IPC: H01Q11/08
Filed: 1976-02-02
Abstract: The helical aerial provides a radio system operating in the UHF band with an improved signal to noise ratio. It also has a more constant impedance in the operating ranges of the order of 50 Ohm. It covers a wider band width and has an increased amplification factor. The coiled element consists of a flattened tube or a rod. The cross section of the rod has a width that is very much greater than the height, i.e. a ratio of width to height of the order of ten to one. The diameter of the turns are variable, so that it can be used for any radio system in the UHF band. The impedance transformer is built into the aerial, i.e. it is formed from the aerial turns itself. The helix (6) can have any number of turns.

Title: Saw mechanism plate stacker - has inserted slides altering in cross section to give stiffness or smooth surface
Inventor: WEHNER BURKHARD
IPC: B65G57/24
Filed: 1976-02-17
Abstract: The plate stacking mechanism is particularly for use in conjunction with a saw parting the plates into sections, where before a stack is thrust onto the support or an existing partial stack a slide is inserted between them. The individual slides (1, 11) can alter in cross-section, being inserted in the vertical position to give the necessary stiffness. They are then swung into the flat position to allow the stack to be thrust over them, after which they are extracted without any tipping taking place. The cross-sectional shape can be altered by erecting two adjacent strips (1, 11) into a roof ridge section, the strips pivoting together along their adjacent edges.

IPC: F24C7/08
Filed: 1976-02-28
Abstract: The electronic temperature regulator, for heating element in eg a cooker, has a control circuit controlling a relay whose contacts switch off the eg 2 kW supply to the heating element. The relay operating power is less than 150 mW. A resistor less than 10 kohms is connected in series with a diode between the ac mains supply and the control circuit.
