Patent DE-4318043-A1 (DE)
Title: Method for manufacturing flat parts of wood
Inventor: LANGER BERND
IPC: B27M1/02
Filed: 1993-05-29
Abstract: The problem on which the invention is based is to obtain chiplessly, in virtually a single operation, the finished surface of the workpieces and also the desired contours and profiles on all sides. A large saving of working time is thereby to be achieved and an ideal prerequisite for mechanised and automated production of such workpieces is to be provided. A further aim is to increase the strength of all moulded-on contours in the surface region by using the method. According to the invention, the flat parts, which are cut out from veneer, are pressed into the mould cavity between upper and lower part of a closed pressing and stamping die, subjected to a pressure lying above the yield point of the wood material, and this subjection to pressure is maintained, with simultaneous heating of the workpiece, over a defined drying time. The starting volume of the unpressed flat part is greater than the final mould cavity of the pressing and stamping die. The field of application is that of all-round surface treatment and shaping, as is required, for example, for the manufacture of wooden cutlery items.

Title: Traveller exchange tool - has an automatic operation and takes up yarn tension at all ring rail positions
Inventor: OTOSHIMA HIROO
IPC: D01H17/02
Filed: 1993-06-11
Abstract: The tool to exchange a traveller has a carrier and an operating section to take up the loop or sag in the yarn through a tenser, passing through the traveller. A second operating section detaches and attaches a traveller. Both operating sections are fitted to the carrier with the first section at a given height level at the carrier and the second section has a vertical movement in relation to the carrier to follow the level of the ring rail. The second operating section also has a yarn grip and a wheel to follow the ring rail with a magnet at the wheel circumference to hold it against the rail. The first and second sections, side by side, act with two further units. The first unit has a setting plate and a roller in contact with the bobbin and can be retracted, and a tenser. The second unit is similarly equipped, together with a yarn grip and mechanisms to detach and attach a traveller. A third unit has a roller in contact with the bobbin, with retraction, and a further system removes the bobbin. USE/ADVANTAGE - The tool gives an automatic traveller exchange at the ring rail of a ring spinning machine, which takes up the yarn tension irrespective of the position of the ring rail.

Title: Survival capsule for global catastrophes - has inner spherical capsule for personnel and supplies floating inside outer spherical capsule with legs
Inventor: GRAFE ERNST DR
IPC: A62B99/00
Filed: 1993-08-31
Abstract: The device for surviving a global catastrophe (like a severe earthquake or seaquake that might arise from a collision of an asteroid with the earth) consists of a capsule system for personnel with survival and propulsion equipment. The spherical capsule containing several passengers along with supplies and observation device, e.g. video camera (24), floats inside a second spherical capsule, this outer capsule being elastically supported on the propulsion equipment.

Title: Jack fastening device
Inventor: BACHER NORBERT
IPC: B60R11/06
Filed: 1993-09-02
Abstract: Device for fastening a jack to the body of a motor vehicle by means of a fastening rod and a first abutment element which is penetrated by the said rod, can be displaced along the fastening rod and can be pressed against the jack, and by means of a second abutment element which is mounted in one end region of the fastening rod and is intended for gripping an edge region of a body part from behind. In order to simplify reliable fixing of the jack, the first abutment element takes the form of a pressure spring for which a stop is formed by a turning handle which is fastened to the other end region of the fastening rod and the second abutment element is capable of being moved along the body part edge region via displacement of the fastening rod against the resistance of the pressure spring and is pivotable below this edge region by means of subsequent twisting of the fastening rod when the pressure spring is in a tensioned condition.
Patent DE-4330042-A1 (DE)
IPC: F16G11/12
Filed: 1993-09-06
Abstract: The subject matter of the invention is an intercommunicating device which can be used between two vehicle units which are connected to one another in an articulated fashion, having a bellows with a clamping device which acts in the peripheral direction of the bellows for fixing the bellows at one end with respect to the associated vehicle unit. The end of the bellows is held in a groove, running in the peripheral direction of the bellows, of a groove-shaped frame profile of the vehicle unit. This end of the bellows is held in the groove by means of tension using the clamping device. The clamping device is a clamping cable whose two ends are held at a variable distance from one another using a clamping lock. When the clamping lock is opened the distance between the two ends of the clamping cable is large and the clamping cable can be lifted over the edges of the groove-shaped frame profile while, when the clamping lock is closed, the clamping cable rests on the base of the groove, the end of the bellows bearing on it, and as a result cannot move over the edges of the groove and out of the groove. The actual clamping lock (8) is assigned a cable retractor (15, 16) with which the original distance between the ends of the cable when the clamping lock is opened can be reduced even by a predetermined degree before the clamping lock is activated. During the closing movement, the actual clamping lock produces the desired final distance between the ends of the cable. <IMAGE>

Filed: 1994-04-23
Abstract: Apparatus for damping thermoacoustic vibrations in a combustion chamber (7), in particular in the combustion chamber of a gas turbine, comprises a Helmholtz resonator (1) having a resonator space (2) and a connecting tube (3) by means of which the resonator space (2) is connected to the combustion chamber (7), a uniform damping performance is achieved even under fluctuating operating conditions when the Helmholtz resonator (1) is equipped with means for controlling the resonator frequency as a function of the frequency of the combustion-chamber vibrations. This may involve controlling the density of the gases in the connecting tube by heating them. Alternatively, a gas feed line leads into the resonator space so that gases of different density can be directed into the resonator space. A control circuit may control the density of the gases in the connecting tube in accordance with the phase difference between the combustion chamber vibrations and the resonator vibrations. <IMAGE>

Title: Electrohydraulic control system and control valve for farm vehicle lifting gear
Inventor: BIENER RAINER
IPC: F15B11/08
Filed: 1994-05-30
Abstract: The invention concerns a control system, in particular an electrohydraulic control system, for hoisting gear, plus an electrohydraulic control valve fitted in the control system. The control valve is designed so that, both in the neutral position in which the hydraulic fluid is held in the hoisting gear and in position B in which pressure in the consumer is released, it provides a connection between a pump and a reservoir so that the amount of fluid delivered by the pump can flow through the control valve into the reservoir. The control system has a bypass line which bypasses the control valve and which brings pressure to act at the consumer when the control valve is in position A in which the connection between the pump and the consumer is broken.
