Patent DE-2818360-A1 (DE)
Title: Adjustable liq. flow divider for hydraulic systems - has two throttles whose cross=sections can be varied while retaining their sum constant
Inventor: TYROLLER JOHANN ING GRAD
IPC: G05D11/00
Filed: 1978-04-26
Abstract: An adjustable liq. flow divider consists of a control valve with two outputs and two-possibly different-throttles at the input, followed by a control piston each, held in a middle position when pressures at the outputs are equal. In this position, the cross-sections of the outlets are also equal. When outlet pressures are different, the piston moves to a position in which the resultant pressure drop due to pressure difference at the two loads and to pressure drops in teh two throttles, is balanced on both sides. A device changes cross-sections of the throttles while maintaining the sum of their cross-sections constant.

Vacant ends of the elastic cutting elements opposite to those held together, establish the tool cutting surface featuring a factor of its filling with the butts of the elastic cutting elements lying within 0.1 and 0.99. Each of the gangs of the elastic cutting elements, as viewed in a longitudinal section are two opposite trapezia spaced equidistantly from the tool axis of rotation and facing the axis with the greater bases. The ratio between the greater trapezium base and the lesser base is determined from a given relationship.

Title: Radar directional vehicle guidance system - is for aircraft, helicopter or ships, with beam modulated to denote angular position within scanning sector
Inventor: WOELKY OTTO
IPC: G01S5/12

Patent DE-2909888-A1 (DE)
Inventor: FRUEH HANS DIPL ING
IPC: G06F17/40
Filed: 1979-03-14
Abstract: The method makes it possible to count pulses arriving via a number of inputs (9) without equipping each input (9) with a separate pulse counter. For this purpose, a one-bit memory (10) and a count memory (11) are allocated to each binary input. The one-bit memory (10) follows a state change in the binary input signal in that a microprocessor (5) which cyclically polls the inputs (9) logically compares the signal state of the in each case associated input signal. In the event of unequal signal states, the one-bit memory (10) is reset and, at the same time, a pulse is added at the count of the count memory (11). <IMAGE>

Abstract: The flowmeter ensures that the effect of the radiation heat on the water vessel wall is considerably reduced. An electric heating element (3) is immersed in the vessel, the heater being fitted with a safety temp. limiter for disconnecting the heating element when the temp. in the vessel has exceeded the max. permitted water temp. In the vessel (1) round the heating element is mounted a sheet metal baffle (11), screening at least a part of the radiation heat impinging on the vessel walls from the heating element. Pref. the baffle is in the form of a screen covering the heating element, possibly in cylindrical form. Alternatively, the baffle is concave, deflecting the radiation heat onto a temp. sensor (7) of the safety temp. limiter (6). The connection between the baffle and the sensor may be heat conductive, but there may be no heat conductivity between the baffle and heating element.

Title: Monitoring system for spray cleaning of food processing tanks - has speed monitoring based on inductive sensor output to check spray head rotational speed
Inventor: TUCHENHAGEN OTTO
IPC: B08B9/093
Filed: 1979-05-08
Abstract: The spray cleaning of containers used in a food processing plant is performed by a rotating spray head and a monitoring system checks that the speed of rotation ties within acceptable limits. The spray head is coupled to a shaft that carries a pick-up to trigger an inductive sensor, once per revolution. The generated signal is processed by a current to voltage converter and is differentiated to produce short duration pulses of a specific time interval. Timing stages define the acceptable period for constant speed rotation. If the interval between measured pulses differ from the set value an indicator is activated and a malfunction signalled.

Title: Automatic fault-detection in textile fabrics - by electronic processing of radiation transmitted or reflected by the fabric
IPC: G01N21/89
Filed: 1979-05-18
Abstract: A process for fault detection in textile fabrics, partic. for use during the prodn. of tufted fabrics, is described whereby the surface of the material is continuously scanned transversely and longitudinally by appropriate electronic receivers which detect radiation, e.g. light or infrared radiation, transmitted or reflected by the material, and produce an electrical output which is related to surface characteristics. Deviations of the output signal from the norm, produced by missing, badly inserted, or deformed threads, are used to halt the machine and produce visible and audible warning signals together with a display indicating the location of the faulty yarn. Faults are detected with minimum delay obviating the costly prodn. of long lengths of faulty material.

Title: Hydraulic pump with differential piston - has auxiliary spring in-side bottom piston half, assisting return at zero position
Inventor: FORSTER FRANZ ING GRAD
IPC: F04B1/32
Filed: 1979-07-25
Abstract: The hydraulic pump with a differential piston in two sections (11,12) down the centre has an inlet (19) communicating with a central chamber (18) with a control piston (21) operating an arm (24) adjacent to the top section (12). An extension (26) acts against a spring (28) above, to allow the bottom part to operate a valve (47) opposite the control piston. This allows medium under pressure to pass from a bottom entry through a series of holes and channels to act against the piston. As the piston moves, the force of the arm varies, and at the zero position of the piston stroke, the piston is assisted by a spring (35) housed inside the bottom section (11). Under the spring is a supporting sleeve (37) which travels downwards against a stop (49) at the bottom.

Title: Tuning device for capacity diodes or coil in receiver - uses identical elements for each tunable diode of coil in resonance circuits and fixed connection between their reactances
Inventor: LINDENMEIER HEINZ PROF DR ING
IPC: H03J7/04
Filed: 1979-09-04
Abstract: In the tuning device the resonance frequencies of the resonance circuit to be tuned are adjusted automatically to a rated frequency. The latter is often the receive frequency, or a frequency associated with it in a given relationship. To each diode or relay to be tuned is associated a reference diode or relay with identical mechanical construction and electric characteristics. A fixed, time irreversible connection is formed between the reactances of the two types of diodes and relays. The signal to be processed, e.g. a receive signal, is supplied to the first resonance circuit only. To the second decoupled diode or relay is additionally supplied a testing signal for its adjustment by a regulating step. In this manner the first diode or relay is adjusted to the desired value. A common reference diode or relay is associated to several elements to be tuned, thus forming a fixed, time irreversible relationship between all elements.

Title: Fuel vaporiser for IC engine - has fuel injected through hub of fan in air inlet manifold
Inventor: BURSA FERDINAND
IPC: F02M17/16
Filed: 1979-10-19
Abstract: A propeller type fan (2) is fixed in the suction side of the inlet manifold (1) of the engine. The fan is driven by a small electric motor (9) and is mounted directly on the shaft extension of the motor. The throttle (4) is in the manifold (1) downstream of the fan. A fuel pipe (3) is taken through a rotating seal into the hub of the fan. The fuel is injected into the air stream through radial holes in the hub and thus mixes with the air as it passes through the fan. This ensures complete vaporisation in the manifold before the mixture reaches the cylinders.
