Title: Multiple injection mouldings made in triple plate press - with all ducts to individual moulds heated to reduce waste
Inventor: MASSANO MODESTO
IPC: B29C45/26
Filed: 1974-06-11
Abstract: An apparatus for injection moulding a large number of articles comprises a front plate, a middle plate and a rear plate, the latter having the small moulds mounted in it. The front plate comprises a central, transverse passage, into which a sleeve with central duct penetrates for passage of material from the plasticiser, the material thus passes through this duct system into the middle plate, which comprises a central duct coaxial with the feed duct through the first plate and prim. branches extending out from this central duct in the body of the middle plate and parallel to its faces, with a further set of sec. branches extending radially from this prim. branch to lead towards the individual moulds, each of these sec. branches passes in succession through a series of chambers, still in the middle plate, each located coaxially to the moulds in the rear plate, each of these chambers houses the upper part of a pin, the lower part of which penetrates partially into the associated mould, each pin has external transverse and longitudinal grooves which conduct the plastics material resp. to the next chamber and transversely to the central plate, into the associated mould, the centre of each pin comprises an axial passage for a heater, and there is a further series of heating ducts, two to each sec. branch for plastics, also lying in a plane parallel to the main faces of the middle plate, this middle plate is thus positively heated, finally in the rear plate, each mould is supplied from the external longitudinal grooves of the pin above it, the bottom apex of this pin extending partly into the mould. The connection between pin and mould is constituted by the collar of the mould itself comprising also an injection nozzle. The pref. heating system for the pins and for the ducts in the middle plate is a set of electrical resistance heaters. The prodn. of waste material in the form of sprues in the feed ducts to the individual moulds is avoided, leading to a much more economical utilisation both of the material and of the injection plasticising machine.

Title: Electric hot water heater with alternative connections - for fitting above or below basins has adjustable internal pipe
Inventor: KALTENECKER GEORG
IPC: F24H1/20
Filed: 1974-11-14
Abstract: The heater is of the non-pressure type and consists of a container (1) with an electric heater (8) in it and two connections (3, 4) in the top and two (6, 7) in the bottom.

Title: Tank farm construction for liquified gases - having outer framework inside which tanks are built, the space then being filled with insulation
Inventor: SCHNEEBERGER MARTIN
IPC: F17C3/02
Filed: 1975-03-19
Abstract: Insulated tank forms for liquefied natural gases are obtd. by building a number of individual tanks inside a common shell. An erection hall is first created which acts as a workshop inside which the tanks are built. When these are complete, the walls of the shell are made gas tight and all superfluous materials removed. Then the spaces between the tanks are at least partially filled with insulating material. The erection hall has rectangular walls and a flat roof. The vertical spaces between the tanks are filled with particulate insulation and the horizontal space on top with an elastic one. Method is for use in the erection of tank farms for storing liquefied gases. The problem is that the best construction techniques can only be used in workshop conditions. This means either building tanks small enough for transport of breaking a temporary workshop on site. The system described uses the latter but enables the structure so produced to be used as the outer shell of the insulation needed in any case. The vessel size can thus be optimised without reference to transport.
Patent DE-2518335-A1 (DE)
Title: Gas valve used in gas fired water heater - is operated by rod from low water sensing arrgt.
Inventor: KEPPEL ERNST
IPC: F16K1/44
Filed: 1975-04-25
Abstract: The valve for a gas fired water heater is operated by a safety arrangement (1) which prevents the water heater burning when no water is present in the system. A rod (2) from the safety arrangement operates the gas valve (3) with seats (4, 5) mounted in the water heater. A gas inlet channel (7) connects to a space below the lower valve seat (4). The operating rod passes through a seal (7) in the wall of the gas channel. The lower valve (4) has a central tubular extension (12) in which an adjustable stop (14) for the operating rod is mounted. A spring disc (16) is mounted on the outside of the extension. Springs act against this plate which press both valves against their seats. The lower valve will open first and give a small through-flow opening. After further opening of the first valve, it will set against protrusions on the second valve and open this valve also.

Title: Hydraulic valves for reciprocating fluid pumps - having two flow resistances positioned for cyclic volume changes
Inventor: ZEIS ALFONS GEORG
IPC: F04B53/10
Filed: 1975-05-05
Abstract: The hydraulic valves are for reciprocating fluid pumps. Two flow resistances are positioned, so that they enclose between them a piston, membrane, or similar, for a cyclic volume change. The resistances are located in the in- and outlet, and apply a high resistance to a medium not flowing in the desired direction. The function of the resistance in the outlet may be taken over by the kinetic energy of the outflowing fluid. With an integral fluid circuit, the working gas pressure of the pump may be increased.

Title: Demountable repair equipment for radio and TV sets - uses columns releasably connected to ceiling power ducts and stackable tables
Inventor: TEICHERT WALTER
IPC: B25H1/02
Filed: 1975-06-06
Abstract: Where the repair shop forms part of a city centre retail site it may be desirable to use the available space more advantageously at those times when the repair facility is not in use. Such multi-purpose use may be achieved by putting the various leads and supplies into, for example, ceiling mounted ducting and using movable power supply and measuring units assembled in the form of a column. Work benches may be in the form of individual stackable tables, with castors if required. By using such a building block system it is possible to assemble the workshop as required and to clear it quickly and easily when the room is needed for other purposes.

Title: Generation of pseudo-random character trains - by allocating constants to initial word in store according to variable algorithm and using resulting digits for further processes
Inventor: GLITZ EKKEHARD ING GRAD
IPC: G07C15/00
Filed: 1975-10-25
Abstract: Signal trains have long periods are generated using at least one store and one arithmetic unit. Starting with an initial word (Xo) and presetting constants (a, a2...2n) in the stores, the initial word (Xo) is linked in the arithmetic unit with selected constants from the series (a1...an) in accordance with a variable alogrithm. The result is a new signal (xq) with q places, of which p places are used as the new signal (xp) and r places for addressing the selection of the next constant (a) from the store. S places are used for selection of the algorithm for the next calculation processes and t places for generation of the next signal (x). when these rules are continued a self-generating character sequence is generated.
