Patent DE-2648957-A1 (DE)
Title: Vapour extractor hood with air intake slots - produces X-shaped air current to avoid draught round users head
Inventor: BLANCKE ROBERT
IPC: F24C15/20
Filed: 1976-10-28
Abstract: The vapour extractor unit for kitchen hobs etc. is provided with slots (1, 2) mounted lengthwise in the hood facing inwards so as to produce an X-shaped air current above the pots, pans etc. on the hob Thus the incoming air supply from the room does not flow directly beneath the hood but more predominantly at the expansion point of the hot vapours so that there is no draught caused around the head of the hob user. The vapours are drawn up through to the filter (3) in a controlled manner. The slots are separated from each other by a fat collecting channel (6) which can be adjusted up or down to widen or narrow down the slots. The air current direction can be altered by rotating the fat channel.

Title: Closing, opening and locking mechanism for two=part tools - esp. for moulding expansible polystyrene beads
Inventor: CERMAK KAREL
IPC: B29C45/67
Filed: 1976-11-19
Abstract: Installation for closing, opening and locking 2-part moulds esp. for mfr. of mouldings from expansible, particulate polystyrene, is claimed. One mould part is connected with the free ends of piston rods which are evenly arranged about a frame and engage cylinders which are evenly arranged about the frame of the other part-mould. The piston rods carry pistons which may be acted upon from both sides. In contract with similar units, the installation takes up practically all the mould closing pressure which has been traditionally absorbed by the machine frame. As a result, the machine frame can now be less heavy and hence less expensive. No additional guide means for the mobile part-mould, and no additional locking means are necessary.

Title: Permanent magnet motor independent of current source for starting - has increasing flux density producing force in direction of rotation by varying airgap
Inventor: ANDRASCH HANS-JOACHIM
IPC: H02K25/00
Filed: 1977-02-17
Abstract: A permanent magnet motor is used which is independent of a current source necessary for rotating the rotor. It will also be driven continuously when a current source is available. The magnetic flux density of the permanent magnets are in an increasing sense in the required direction of rotation. The step from the highest to the lowest magnetic flux density is overcome by a mechanical, electromechanical or electromagnetic switching circuit. The motor shaft (3) is mounted on a front (1) and back (2) support plate. The rotor consists of three permanent magnets spaced at an equal angle around the shaft. The difference in flux density is achieved by varying the gap between rotor and stator.

Title: Extraction of copper from raw material high in antimony - by melting in contact with iron-rich slag to reduce antimony to allow subsequent electrolytic refining
Inventor: PETERSSON STIG ARVID
IPC: C22B15/00
Filed: 1977-03-12
Abstract: Process for removing Sb and Cu matte on melting Cu raw materials contg. >0.2% Sub such that the Cu raw material is melted by heat supply from a burner in an inclined rotary furance together with an Fe-contg. salt which is added to the furnace so that Fe in the furnace is at least 44 x greater than the Sb quantity. The resulting Cu melt is reacted in the same rotary furnace, in conjunction with removal of slag, with O2 introduced through lances to produce a white metal and a further slag which is finally removed. The process is an economic and efficient method for removing Sb and Cu to a level to allow electrolytic refining. Pref. heat is provided by an oil burner in two phases, first a reducing phase with 80% stoichiometric O2, second an oxidising phase with 120% stoichiometric O2. The first phase achieves a temp. of 880-980 degrees C and the second 1150-1300 degrees C. The furnace, which can be a Aldo converter, rotates at a circumferential speed pref. of 2-5 m/sec. and material falls from the walls in drops to give a fast reaction.

Title: Ultrasonic test equipment amplifier - handles widely different amplitudes by selecting output of appropriate stage in amplifying chain
Inventor: QUITTKAT JOERG ING GRAD
IPC: G01N29/40
Filed: 1977-06-30
Abstract: The amplifier, is designed for use in ultra-sound test equipment. It has a large signal-to-noise ratio for input signals of greatly differing amplitudes. The amplifier consists of a chain of separate amplifying stages (V1, V2...Vn) switched in and out depending on the magnitude of the input signal's amplitude. An input signal with a large amplitude means that the amplifier output (UA) is taken from an amplifying stage lying nearer to the input end of the chain than it would for an input of smaller amplitude.

Title: Throw away folding soft sleeve flower vase - has inner sealed sleeve causing stabilising air compression when filled with water
Inventor: BOHLMANN KARL-HEINZ
IPC: A47G7/06
Filed: 1978-05-08
Abstract: The upper edge of the vase foil is fitted with a second inner foil sleeve in the form of a tube which when fixed has an air-tight seal. The length of the inner sleeve is determined by the desired amount of air. When the vase is filled with water the air between the vase and the inserted sleeve is compressed so that the upper part of the vase is sufficiently rigid to prevent the neck from bending over. The vase still retains its flexibility and foldability but there is now no danger of the vase tipping over when filled with flowers.

Patent DE-2837433-A1 (DE)
Inventor: SHIMIZU KEIICHIRO
IPC: G02F1/1368
Filed: 1978-08-28
Abstract: The liquid-crystal display panel in a matrix arrangement has a pair of bases (40, 42), one of which (42) carries a plurality of gate lines (44), a plurality of source lines (50) perpendicular to the gate lines and a thin-film transistor arrangement at each intersection point between the gate lines and source lines, while the other base (40) is provided with a transparent and electrically conducting layer (41). A layer (54) comprising a liquid-crystal material is inserted between the transistor arrangement on the one hand and the transparent and electrically conducting layer (41) on the other hand. The thin-film transistor (44, 46, 48, 50, 52) has a semiconductor layer (48) of tellurium which offers the considerable advantage over the known cadmium selenide or cadmium sulphide layers that it can be manufactured uniformly and homogeneously and that it shows no change in conductivity in the presence of incident light. Moreover, there is no need for the relevant base (42) to be heated separately when the tellurium layer is applied. <IMAGE>
