Patent DE-3434366-A1 (DE)
Title: Mould for producing mouldings by backfilling film shells with a plastics moulding compound
Inventor: EISSLER EWALD
IPC: B29C45/14
Filed: 1984-09-19
Abstract: The invention relates to a mould for producing mouldings by backfilling semi-rigid film shells which have an undercut edge, are inserted into the mould and are preferably already preformed, with a curing plastics moulding compound. Mould parts which are centrally arranged at the top and bottom side, together with laterally arranged mould parts, form the mould cavity. In order to eliminate the trimming of the film edges in an operation following the moulding operation and in a special trimming machine, the laterally arranged mould parts are equipped with a knife-shaped pinch edge. During the closing of the mould, the pinch edge in a common parting surface between the lateral mould parts and a central mould part, on the one hand clamps the film edge projecting from the mould cavity in a sealing manner and, on the other hand, simultaneously provides it with a predetermined parting line, along which the edge to be parted off is torn off either automatically during demoulding or manually after demoulding.

Title: Device for measuring the temperature in water-cooled metal walls of metallurgical vessels, in particular continuous casting moulds
Inventor: PLESCHIUTSCHNIGG FRITZ-PETER D
IPC: B22D2/00
Filed: 1984-10-04
Abstract: A temperature measuring device of this kind with thermocouples (5) has thermoelectric wires or thermoelectric metals (7) which are each arranged in transverse holes (4) in the metal walls (1a). 
<??>In order to avoid a long, slow measuring section and at the same time to achieve secure protected accommodation of the thermocouples (5), it is proposed that each of the transverse holes (4) be sealed by means of a thermally stable and wear-resistant protective layer or protective wall (6) with a thickness (D) less than 4 mm and greater than 0.25 mm applied to the metal wall (1a) facing the molten metal (3).

Patent DE-3444112-A1 (DE)
Inventor: SEUFERT WALTER DR
IPC: C07C33/025
Filed: 1984-12-04
Abstract: An olefinically unsaturated compound, in particular a very pure cis-isomer of an alkenylhydroxy compound of the formula CH3(CH2)m-CH=CH-(CH2)n-OR (I), where R is hydrogen or a protective group which can virtually be eliminated, m is from 1 to 12 and n is from 1 to 10, is obtained by catalytic partial hydrogenation of the corresponding acetylene derivative over a supported catalyst which contains from 0.05 to 5% by weight of palladium and from 0.05 to 15% by weight of zinc and/or cadmium.
Patent DE-3445464-A1 (DE)
Title: Device for stabilising the oxygen content in rooms with a controlled atmosphere by means of room pressure-balancing accumulators without auxiliary energy
Inventor: SIMON REINHARD DIPL ING
IPC: A23B7/148
Filed: 1984-11-20
Abstract: To obtain a required low oxygen content of down to 1.3% by volume in rooms with a controlled atmosphere, for example for storing fruit in gas-tight storage rooms, a device is required which balances the room pressure relative to the external air atmosphere in a gas-tight room pressure balancing accumulator down to less than 0.3 mbar. The ingress of external air caused by the switching difference of the cooling thermostat or by changes in air pressure is reduced or entirely avoided by a room pressure-balancing accumulator. The room pressure-balancing accumulator consisting of PVC-coated plastic fabrics fills and empties without auxiliary energy. The differential pressure from the storage room to the external air is used directly for varying the accumulator volume. The accumulator is designed as a structural space, for example as a cube or oblong, and it can automatically alter its volumetric capacity by crumpling due to a highly flexible crumpling zone. The room pressure balancing accumulator is connected to the storage room via a pipe and, for maintenance reasons, is located outside the storage room, preferably above the cold store door. To obtain a highly effective sensitivity, the deadweight is preferably compensated via rollers with ball bearings.

Title: Protection device for an induction coil
Inventor: JUERGENS HEINZ DIPL ING
IPC: H05B6/02
Filed: 1984-12-14
Abstract: In order to prevent damage to the induction coil (11) as a result of bars or rods (13) which are bent or run through obliquely, it is proposed to arrange at least one electrical, bare conductor (which is connected to insulation monitoring) within the passage opening (12) of the induction coil (11), along the movement direction of the bars or rods (13). As a result of the insulation monitoring, if the bar or rod is touched with the electrical conductor (16, 25), an electrical circuit is closed and an electrical control signal is emitted in order to stop the feed movement of the bars or rods (13). <IMAGE>

Title: Process for generating dark surfaces on gold alloys
Inventor: KNOSP HELMUT DR
IPC: A44C27/00
Filed: 1985-01-25

Title: Method and installation for the production of metallic materials containing voids, in the form of sections
Inventor: WEBER JOSEF
IPC: B22D25/00
Filed: 1985-05-09
Abstract: The invention relates to a method for the production of metallic materials containing voids, in the form of a section, by continuous casting and to an installation for carrying out such a method, by means of which metallic materials, e.g. those consisting of steel, containing voids can be produced in the form of sections which have a relatively high moment of resistance under bending, buckling and torsional loads in relation to its own weight and furthermore have desired secondary properties such as low thermal conductivity and lower permeability to sound. According to the invention, the solution consists in that a gas is fed continuously into the upward flowing molten metal at at least one point underneath a continuous casting mould. <IMAGE>
Patent DE-3520554-A1 (DE)
Inventor: SCHMITT MANFRED
IPC: G05D16/06
Filed: 1985-06-07
Abstract: The pneumatic pressure switch is designed in particular for controlling the air pressure chamber (4) of additionally loaded safety valves (1). In this case the air pressure chamber (4) is connected to a compressed air source (5) for supplying air and an outlet valve (9) for discharging air which is controlled by the pneumatic pressure switch. The pressure switch consists of an expansion device (10) which is connected to the pressurised fluid line and whose movable and pressure-tight end (15) is constructed as a closure device of the outlet valve (9). The valve seating (16) is flexibly connected to the air discharge line (8) and rests on an elastically suspended support (17) which is coupled to two control air chambers (24, 25), one of which is connected to the compressed air source (5) and the other to the air discharge line (8), so that the support (17) can be displaced in both directions in order to control the valve lift. Depending on the impingement direction, this displacement acts as positive or negative feedback, as a result of which the dynamic switching behaviour of the safety valve can be substantially altered. The outlet valve (9) can also be used as a pilot valve for a servo valve having a larger air outlet. <IMAGE>

Title: Incubator having a microwave device
Inventor: SCHUBERT WERNER DR MED
IPC: D06F35/00
Filed: 1986-03-03
Abstract: The use of microwaves to treat substances in liquids makes special devices necessary. For this purpose, an incubator can be used for various purposes such as cleaning or for fixing organs or organic tissue, it also being possible to provide combination effects of chemical or physical systems with a dominating influence of the microwaves on a substance. As much microwave energy as possible penetrates into a substance if it is located as closely as possible over the baseplate of the tank of the incubator and thus relatively closely over the antenna or the regenerator of the microwave device, and also remains there, even though a large number of cavitations, primarily as a result of water vapour, produce lift in the substance, as must result, for example, during the cleaning of textiles if a very large number of gas bubbles are produced between the fibres just as a consequence of the influence of the microwaves.
