Title: Buffer memory for time shared process control - control unit shifts data held in small capacity buffer of CCD shift register
Inventor: SCHNEIDER PETER DR
IPC: G06F12/0842
Filed: 1975-03-06
Abstract: A buffer memory located between a central processor and the main store facilitates processor (ZD) issues an address instruction (AD) to the control section (HM) of the buffer store (CA). If data is held in the buffer it is transmitted to the central processor (WO). If not a data block containing the required word is extracted (BL) from the main memory (HS). A control unit (CS) provides a means of tracking the processes under control. The next process to be controlled is indicated by a signal (PN) to generate a clock signal (T2) to shift the contents of the buffer memory. The buffer memory is based upon a shift register using (CCD) devices.

Title: Storage heater with fan and direct acting radiator - control ensures that energy consumed in high tariff period is less than in low tariff
Inventor: KREIKENBOHM ROBERT
IPC: G05D23/24
Filed: 1975-06-25
Abstract: Control of storage heater which includes a heat accumulator with radiators (1), a fan (2) and an auxiliary direct-acting radiator (3) is carried out by heating the heat accumulator in the low-tariff period only for as long as temp. is below nominal room temp. When a given first difference occurs between nomonal and actual room temp, the fan is switched on. In the high-tariff period, the fan is switched on for as long as temp. is below nominal room temp. The direct-acting radiator is switched on in the high-tariff period only when a given second difference occurs between nominal and actual room temp. which is less than the first difference. The max. energy consumed by the direct-acting radiator in the high-tariff period is less than that consumed by the heat accumulator or its radiators in the low-tariff period.

Title: Fresh water and salt prodn. - from seal water in multichamber expansive evaporators with independent brine circuit
Inventor: MATTERN KONRAD
IPC: B01D9/00
Filed: 1976-01-17
Abstract: Sea water can be converted to fresh water and common salt by distn. and preconcentration in an integrated heat technology plant. The distn. and crystallisation is performed in a multichamber expansive evaporator with its own brine circuit, independent of the fresh water generation plant. This circuit is fed with a pre-concentrate which is yielded as a byproduct of the fresh water generation. This couples the fresh water generation with the common salt prodn. in the most advantageous way. Brine which is a byproduct of the sea-water distn. is utilised at a high efficiency without impeding the two plant sections in their different operational requirements.

Title: Control disc for hydrostatic axial piston machine - has rotating cylinder drum with pressure compensation depending on pump head
Inventor: BORNHOLDT SIEGFRIED
IPC: F04B1/20
Filed: 1976-01-20
Abstract: Control arrangement consists of a flat disc (1) with two arc shaped control openings (2,3). The ends of the control slots run into bores (5,6) in which spring-loaded pistons (7,8) are mounted. Spaces either side of the pistons are connected by channels to the control slots. Beyond the pistons, the control grooves run into throttle grooves (18). At low working pressure, the pistons are pushed down by the springs so that the throttle grooves are connected directly to the control openings causing a small degree of overlap. If the machine is used as pump, a small amount of pre-compression occurs. The bore in which the piston is mounted can be arranged so, that with retracted piston the degree of overlap is smaller than one.

Title: Channelled building block divisible into corner stones - has fracture points on channel and external face intersections for on site adaptation
Inventor: KELLER HEINZ
IPC: E04B2/02
Filed: 1976-03-02
Abstract: The shaped building block, esp. of the type made by extrusion, can be easily divided into two corner blocks on site, as required in external wall building where a cross wall, window or other element has to be fitted in. It incorporates a channel, or more than one, passing through it from one outside face to the opposite one.

Title: Hand brake control with selective braking - has setting lever on linkage yoke to block one wheel
Inventor: PRAUSE JOHANNES DIPL PHYS
IPC: B60T8/32
Filed: 1976-10-26
Abstract: The handbrake lever (11) is linked to the two brake linkages (13) to the rear wheels (14) by a yoke (15) to balance out the brake force. The yoke can be displaced by a second lever (17) so that only one wheel is braked. This is used when one wheel loses grip and vehicle cannot be moved out of soft ground. The driver merely sets the handbrake and then sets the selective lever to either side until the vehicle moves. For hydraulic parking brakes, the modulating lever operates a hydraulic valve to alter the distribution of braking force.

Title: Dishwasher with effective cleaning even with clogged filters - has mesh filter coming into operation as water level rises
Inventor: HEISSMEIER WALTER DIPL PHYS
IPC: A47L15/42
Filed: 1976-12-14
Abstract: The dishwasher contains a filter consisting of a funnel-shaped fine mesh sieve (6) which leads into a finer mesh cylinder (8) which in the drainage trough (2) defines a connecting pipe (3) for the emptying duct (7) and of a large mesh sieve (9) mounted inside the said cylinder. The fine sieve (6) extends from the level (12) of the water when the pump circulates to the normal water level (13) when the pump is stationary whilst the finer mesh cylinder (8) extends from the circulating water level (12) to a gap (a) above the base (4) of the drainage trough. The large sieve is in the form of a basket (9) whose base (10) forms the lower end for the emptying duct (7). Even when the large sieve is blocked up at the base of the emptying duct the cleaning action of the machine is still maintained since the water level rises in the wash container and can be drawn off by the pump via the fine sieve. Provided the base of the sieve basket remains free of deposits part of the water can still be drawn off via the emptying duct.
