Title: Wire wrap connection using aluminium wire - involves twisting sharp edge aluminium pin after bare wire has been wrapped around it
Inventor: OESTREICH ULRICH DIPL ING
IPC: H01R43/033
Filed: 1975-02-25
Abstract: The wire wrap technique of joining a conductor to a contact pin with sharp edges without solder has been applied to metals such as aluminium which cannot be tensioned enough to produce a cold weld and which tend to form an oxide skin. The aluminium wire (1) which still carries the insulation (3) over the first turn is wraped with a normal tension around the contact pin (2), made of a hard aluminium alloy. After the wrapping operation the tip of the pin of gripped by a total and twisted (4) through an angle of up to 2 Pi per wrapped conductor length. This produces a good non-ageing contact.

Title: Automatic frequency trimmer for mechanical resonators - has resonators, passing magnetiser, processing station and frequency tester
Inventor: SCHEEF HERBERT DIPL ING
IPC: G04D3/00
Filed: 1975-03-24
Abstract: The automatic frequency trimming system for mechanical resonators has the resonators fed by a conveyor onto the circumference of a rotating table that carries them to a first station (6) where they are magnetised. From the first station they pass individually to a treatment station (16) and from there on to a measuring station (20) which generates a magnetic field, using an oscillator, and compares the resonator actual frequency with that of the required frequency. The resonators are then rejected or accepted according to the test result.

Inventor: KARGER FRIEDBERT DR
IPC: H05H1/12
Filed: 1975-05-09
Abstract: The plasma coil device is for fusion generators, such as Tokamak, and selectively influences plasma using a roughly helical magnetic field, whose helicity bears a given relationship to the helicity of certain magnetic lines of force inside the plasma. This helical field is generated separately from the screwed magnetic field in the toroid and is allowed to interact with the plasma. The helical magnetic field has a pitch which is greater than or equal to one, and bears a given relationship to the pitch of the magnetic lines of force requiring influencing over a given surface of the plasma.

Title: Foil for preventing water loss by evaporation - has projections and perforations opening and closing depending on temperature
Inventor: HOELTER HEINZ
IPC: E02B1/00
Filed: 1975-08-16
Abstract: The foil for preventing evaporation can float on the surface of a body of water. It is also stabilised against wind and its evaporation protection varies with given weather conditions. At night dew can be collected through the foil. It may have projections on its underside and a reflecting side facing the sun. A reflecting coating can be applied. This foil has perforations to drain any leaked or rainwater on the foil underside, in the main body of the water. Alternatively the air side can be a dark colour and its underside a bright reflecting colour. The foil material may have high expansion characteristics so that the holes in the foil can be almost closed under hot sunshine. On cooling for example in the evenings the perforations open.

Title: Printing unit with longitudinally movable printing wires - has wires wetted with ink directly by capillary action from supply container
Inventor: HAUGK ANDREAS ING GRAD
IPC: B41J27/20
Filed: 1975-10-18
Abstract: Printing unit with longitudiannly moving printing wires employs an ink feed system which is suitable for high speed printing and directly links-up the ends of the wires. The ink travels by capillary action through the channels which guide the wires and thence up to the wire ends. The ink-supply chamber (2) and the ink surface (11) lie below the printing wires. The ink (1) travels with capillary action through a narrow channel (5) between the chamber and all the guide channels (3) for the wires (6). The uniformity of ink supply and the contrast of the printd symbol is further improved by the incorporation of an additional capillary tube (7) located between the first channel (5) and the front ends of the printing wires.

Title: Control system for hydrocarbon hydroconversion processes - to monitor process parameters and regulate hydrogen hydrocarbon mole ratio
Inventor: BAJEK WALTER ADAM
IPC: C10G35/24
Filed: 1976-07-31
Abstract: A technique for controlling the hydrogen/hydrocarbon mole ratio in continuous, catalytic, hydrogen-consuming or hydrogen-producing hydrocarbon conversion processes involves employing analysers to monitor composition characteristics of the charge stock and of the liquid reaction effluent and the hydrogen concentration of the vaporous phase introduced into the reaction zone, and transmitting representative output signals to comparator/computer means which generate additional comparator output signals which are utilised in the control system for regulating the H2/hydrocarbon ratio. The technique is applicable to processes in which the reaction zone effluent is separated into liquid and H2-rich vapour phases, a portion of the latter being recycled to the reaction zone.

Title: Pen type transducer converting hand written data to coded signals - uses HV pulses applied to pen and has printed circuit matrix
Inventor: POPP HANS-PETER ING GRAD
IPC: G06V10/12
Filed: 1976-10-30
Abstract: A simple transducer is used for converting hand written data, typically numbers and letters, which are written on a sheet of paper using a special voltage probe pen, to coded signals. A table under the paper carries a printed circuit matrix connected to an array of two dimension address registers. A high voltage pulse carrying pen (10), containing a high resistance and suitably insulated, is used to write the information on a paper sheet, which is laid for the purpose on a table element consisting of a printed circuit XY matrix. Arrays of X, Y bistable circuits (4, 5) detect where the pen is at any instant, the whole arrangement being sampled 25 times per second. This data is converted electronically to the form required, typically for transmission to a remote display or pen recorder.

Title: Foundry cores made from sand contg. no binder - using plastic foils drawn into two core box halves by a vacuum and then welded together
Inventor: GROLLA HERBERT ING GRAD
IPC: B22C9/03
Filed: 1976-12-21
Abstract: Cores are made using a binder-free sand consolidated by a vacuum. Each core box half contains a vacuum pipe, and a plastic foil is laid on top of the box so the vacuum compels the foil to match the contour of the box cavity and the core print; heat may be used to assist the shaping of the foil. A vacuum pipe (I) is then placed in the core box cavity and the two core box halves are assembled so the two plastic foils are in contact on their flat surfaces. Binder-free sand is poured into the box cavity to surround the pipe (I) and consolidated by vibration; the sand inlet hole is sealed and a vacuum applied via pipe (I); the vacuum in the two box halves can then be released so the finished core can be removed. The two foils are pref. welded together along their adjacent edges. The prodn. of binder-free sand moulds surrounded by plastic foils and evacuated is now well established; the invention provides a simple and economic method of mfg. cores by a similar method.

Title: Gas detector sample pressure regulation - is for corrosion or condensable gas using regulator isolated from heat and gases
Inventor: MUELLER FRIEDHELM ING GRAD
IPC: G01N27/62
Filed: 1977-01-17
Abstract: A device for regulation of press. of gas supplied to a gas detector for analysis is designed for use with gases which are chemically active or contain condensable constituents. These gases normally necessitate stainless steel construction and high temp. operation not suitable for sensitive press. regulators. The gas is supplied to the analyser via a choke. A connection for the regulator is positioned upstream of the choke in the supply pipe. An auxiliary gas regulator and a flow impedance are connected to the connection. The auxiliary gas used is compressed air or other insert gas, and the impedance is a needle valve or capillary shoke of stainless steel which isolates the regulator from heat and corrosive gas.
