Title: Tape or video recorder motor control circuit - uses tachogenerator to supply motor speed pulses for phase-coupled control loop
Inventor: MINAKUCHI HIROSHI
IPC: H02P23/18
Filed: 1979-06-05
Abstract: The motor control system suitable for equipment such as tape recorders, video recorders etc., uses a phase coupled control loop and a frequency shifting system for changing the frequency of the drive. The circuit includes a device such as a tachogenerator for obtaining pulse signals corresp. to the motor speed and a quartz controlled oscillator to provide control pulses. This is connected to a frequency divider with an input for a programmer. The output is passed to a phase equaliser which also receives the pulses from the tachogenerator. This is interconnected with a control unit with a pulse counter which receives two digital control values above and below the oscillator frequency. Control signals thus obtained are passed to a mixer which controls the motor speed.

Title: Multiplication of pneumatic pressure for hydraulic circuit - uses pre-constrained helicoidal spring to support rigid plunger piston
Inventor: MEISE GUNTHER
IPC: F15B3/00
Filed: 1979-07-04
Abstract: A pressure multiplier has a piston which is sealed in the operating mechanism and supplied with fluid under pressure. This is connected to a plunger piston to output a hydraulic pressure.

Title: Plastics fencing unit esp. for gardens and camping - has tongue and groove at ends for connecting to adjacent elements
Inventor: THEILER JOSEF
IPC: A01G9/28
Filed: 1979-11-09
Abstract: A fence element is intended for flower beds, tent areas and the like is designed to be hand-driven into the ground and is of plastics material.

Title: Receiver synchronising circuit for digital data transmission - includes signal delay unit and bit pulse phase measuring circuit
Inventor: WINKELMANN HEINZ ING GRAD
IPC: H04L7/033
Filed: 1979-11-20
Abstract: The circuit eliminates the need to transmit and evaluate a special code word at the start of each transmission and thus achieves a higher transmission rate. The filtered incoming signal is applied to the input terminal (1) of a delay unit (4) with a delay time of one data block length, typically 16 bit pulses. A processor (6) in series with the delay checks the individual data bits in their mid position, and regenerates the signal with clean edges. In parallel with the delay unit is a phase comparator (5) which determines the phase position of the bit pulse signal. The unit contains an integrator representative of the time delay unit. The output gives the mean pulse phase position of the bit pulse signal over one block length which is applied to the control input of the processor (6).

Title: Adjustment system for tool of press - eliminates eccentric turning moments on support columns by moving reference point
IPC: B21J13/00
Filed: 1980-05-03
Abstract: The adjustment system measures electrically the difference in the expansion of two diagonally opposite columns of the press and passes the result to an evaluator that serves a display screen with X and Y axes. One line joining the columns forms the X-axis and the other line the Y-axis. The press has four columns. The two measurements appear as a point in the XY coordinate system. The reference point of the tool is displaced against the direction of the vector of this point and by a distance proportional to the vector's length until the vector is zero. The system thereby eliminates unwanted eccentric load moments on the column.

Patent DE-3024518-A1 (DE)
Inventor: LORCH WERNER
IPC: F16K11/087
Filed: 1980-06-28
Abstract: A single mixing valve has a ball-like valve plug with hot and cold water inlet ports and outlet ports and a valve housing having a valve seat face of the same form as the plug. The housing has inlet ducts for the hot and cold water to be mixed and an outlet duct for the mixed water, the ducts porting into the face. A driving part is joined with the plug and is able to be rocked therewith for changing the rate of outlet of water from the valve and to be moved for changing the mixing ratio of the hot and cold water. The driving part is limited in its rocking motion to motion about a rocking axis running through a middle point of the plug and is limited to turning about an axis of turning running through the middle point. The valve has a guide plate, which may be turned in a plane parallel to the rocking axis of the driving part, with same in relation to the housing. The plate has a slot in which the driving part is keyed while being able to be moved along the slot. With this system it is not possible for the plug to be moved into skew positions.

Title: Lorry trailer for crane transportation - has crane base locked between two-trailer halves during transport and convertible to carry normal goods when removed
Inventor: HUNEKE OTTO
IPC: B62D53/06
Filed: 1980-07-12
Abstract: This lorry trailer for transporting tower cranes is in two parts, a front saddle (10) and a central frame (11) which carries a folding platform (14). Each half connects to the crane base frame (18) via carrier consoles (12). For the coupling process, the rear axle is removed and the frame suspension is lowered sufficiently to allow locking pins (19) to be fitted in the consoles. The suspension is then raised and the rear axle replaced. Uncoupling is achieved by the reverse process. After uncoupling the two parts are fitted together by the consoles. The axles are relocated on the central frame and the loading platform unfolded for use transporting other goods. The trailer need not return empty, thus cutting transport cost.

Title: Modular solar energy collecting system - concentrates radiation into heat store used for heating medium in power producing cycle
Inventor: SPEIDEL KARL
IPC: F24S23/79
Filed: 1980-07-29
Abstract: The modular assembly comprises an array of mirrors (16) which concentrate solar radiation into the centre of a heat store (15), e.g. via a swivelable convex mirror (17). The centre of the store may contain a steel wool-filled sphere (19) which transmits the heat via a concentric spherical area (20). This area is filled with steel or cast iron scrap, to a sand-filled space (21) around it within a jacketed container (15), the jacket being evacuated. Concentric toroidal chambers (high 23, medium 24, and low-temp. 25 chambers) surround the heat store, and energy is transferred from these chambers to a power producing engine e.g. by air flowing through them. Alternative modular radiant heat exchange units may be used as well as different types of engines.
