Title: Manually operated pump for grouting anchors in masonry holes - has outlet with alignable holes in relatively rotatable plates to form control valve
Inventor: FISCHER ARTUR DR
IPC: B05C17/01
Filed: 1977-08-20
Abstract: The injector has an opening(4) through which the grout is forced by manual depression of a plunger. The opening can be closed at the termination of the injection phase to obviate a reversal of grout flow at the mouth of the hole. The head of the injector may be covered by two parallel plates (12, 13), each with an offset opening, and forming a simple slide valve. The external plate(12) may be rotated to effect the coincidence of the openings or vice versa. The outer plate(13) may have an axially projecting nose(9) with a radial projection(10). The nose(9) engages a matching recess (11) in the anchor unit(7) to positively locate the injector at the start of the operation.

Title: Necklace link mfg. system - applies tensile force to ring section ends, for reef knot connection
Inventor: QUANTE HEINRICH
IPC: A44C27/00
Filed: 1977-08-31
Abstract: The process is for the manufacture of a double-link element for a pin or a neck lace consisting of several links. The element is formed from two rod-or ring-shaped sections, which are deformed, loosely linked in a reef knot, and fastened to each other. The outer ends (3, 4) of the connected sections (1, 2) are subjected to opposite tensile forces, until plastic deformation and permanent connections result. The lements thus formed is linked to another section or a complete element, and again subsequently deformed toa chieve a permanent connection.

Title: Solar energy collector using buoyant reference platforms - increasing accuracy of concentrating system by shortening reflection lengths
Inventor: KOESTER HELMUT DIPL ING
IPC: F24S23/70
Filed: 1978-01-16
Abstract: In a range of installations for the collecting of solar energy the angle between the incident radiation and the reflected beam relatively to the azimuth, remains constant, and the reflector surfaces are arranged on a reference platform which rotates on a vertical axis and floats on a medium giving buoyancy, or is connected to a floating body. This follows a horizontal circle so that the shadows of the collectors and the reflectors always fall on the platform in the same direction. The system is designed (1) to increase the efficiency of the reflectors, (2) to reduce simultaneously the costs of the mechanisms for aligning the reflectors, (3) to reduce the area necessary for the installation by improving the reflector aligning system and (4) to increase the accuracy of the concentrating system by shortening the lengths of reflection.

Title: Deodorisation of sulphurous and nitrogenous gas - from plant for processing vegetable and animal prods.; uses acid, chlorite and alkali scrubbing stages
Inventor: HOELKER GREGOR ING GRAD
IPC: B01D53/72
Filed: 1978-05-26
Abstract: Purificn. of foul-smelling sulphurous and/or nitrogeneous waste gases from plants for processing vegetable and animal prods. involves treatment with alkaline(ne earth) chloride soln. at pH 1-5, the gases being scrubbed with an acid at pH 1-5 before and with an alkali soln. at pH 6-14 after treatment with the chlorite soln.

Title: Multicore power transmission cable with auxiliary strands - has core insulation with thicker sections producing enlarged wedge-shaped gaps
Inventor: KOTHE GERHARD DR
IPC: H01B9/00
Filed: 1978-10-07
Abstract: A multi-core cable has additional strands for use in power transmission. They are placed in the gaps between adjacent cores. When combined, they can be used for the transmission of additional power in emergencies. The four main cores are made from solid sectional metal (1) which is aluminium, with rounded corners and equivalent to a sector in the cross-section. They are insulated (2) and combined in the conventional manner to form a power cable. The insulation of the main cores is thicker on the sides facing the sheathing (4), thereby producing a larger wedge-shaped space (3). This enables the dia. of the additional strands to be increased. The section in the centre (7) can be filled with an additional strand or a filler. The space (3) between the sheathing can also be packed with a filler.

Title: Multiple transmitter radio network coordination system - reduces probability of simultaneous transmission by coding and identification of station for priority rating
Inventor: EICHLER PETER ING GRAD
IPC: H04B7/24
Filed: 1978-10-12
Abstract: Coordination circuit will regulate the transmission times of different transmitters belonging to a number of stations of a radio network. The coordination circuit is automatically controlled if central synchronisation is not possible. It will reduce the probability of simultaneous transmission by more than one transmitter. Each station will have an identification code with an index number. In addition to its own identification or its own transmission time, each transmitter will contain a circuit which will automatically add the code of the first transmitting station to the radio telegram to be transmitted. This code will act as a reference for the order of transmission and the time of the station concerned. It will determine whether the index number of the station concerned is greater or smaller than that of the station destined to transmit first.

Title: Voltage measurement and display circuit - has two linear regions and one or more precision voltage limiters to effect change of scale
Inventor: LEOPOLD HANS PROF DR
IPC: G01R15/00
Filed: 1979-04-11
Abstract: The voltage is measured by a moving coil meter (3) with a series resistor (4). In parallel with this is a second resistor (2) in series with a precision voltage limiter (1). This second resistor effects a change of the scale of the measurement for voltages large enough to cause the limiter circuit to conduct. The precision limiter circuit uses three transistors driven by a resistor divider network. Temp. compensation of the transistors is provided by negative temp. coefficient resistors in their base drives. More than one change of scale can be effected in the same way.

Title: Thermoelectrically controlled carburettor - has thin metal foil wetted by fuel film in float chamber
Inventor: BEYER GUSTAV
IPC: F02M15/04
Filed: 1979-05-21
Abstract: The simplified carburetter ensures the evaporation of all fuels by thermoelectric heating which optimises the work. The bulk of fuel is held in the float chamber which is surrounded by the electric heating coil of metal foil. The foil surface is wetted by the fuel to ensure continuous evaporation with the fluid film reaching from centre of the chamber, without hindrance. This results in economical and reliable evaporation of fuel with the foil heated up by the starter current without appreciable delay. Elimination of residual gases when engine is stopped, is by fitting a butterfly valve in the channel leading to the mixer pipe. The valve is operated by a solenoid with circuit in series with the ignition lock.
