Abstract: Apparatus for cooling rolled wire rod consists of a first part which guides the wire rectilinearly and cools it with water, a turn-laying unit which forms the wire into turns and lays the turns in staggerred disposition on a continuously running conveyor, and a second part comprising the conveyor which allows passage of an approximately vertically directed stream of air to the turns and conveys the wire turns to a coil forming station which collects them. In order to provide substantial adaptability to various cooling requirements by means of simple and inexpensive conversion, the two parts are composed of a plurality of modules of the same modular length or an integral multiple of the modular length. A base frame carries the modules and the turn-laying unit is fixed on the base frame in a longitudinally displaceable manner. Thus, the lengths of the first and second parts can be changed, and individual modules or groups can be replaced.

Filed: 1989-09-06
Granted: 1991-02-14
Abstract: A detector senses the scattered light at the optical component transmitted from a light source. A pulsed operated light source (2) produces a sequence of light pulses (24, 24'), the pulse duration (t) of which is short compared with the transit time of the light through the system. An electronic unit (14) blocks the detector (6) after a time (T5) following the transmission of a light pulse for a specified time interval. The time (T5) is larger than the transit time (T2) of the light pulse from the light source (2) over a further scattering or reflecting object (9) arranged behind the optical component (5) in the beam path to the detector (6) and through a vacuum chamber (1) in which the optical system is arranged. USE/ADVANTAGE - Facilitates measuring of scattered light part of extremely slight scattered light of optical components, their total scattered light part being smaller than 10 to the power of minus 6. Examining surface roughness of optical layers or material homogeneity of optical components, e.g. lenses.

Patent DE-4111164-C1 (DE)
IPC: B29C45/23
Filed: 1991-04-06
Granted: 1992-07-02
Abstract: A closure element (12) is disposed in a manner so as to be axially movable to a limited degree in an end section of relatively large clear width of the nozzle channel (16). In a forward position (injection position), this closure element permits a flowing of the plasticated plastic from the nozzle channel (16) to the nozzle opening (14). In a rearward closure position, the closure element (12) covers the nozzle channel (16) at its front side under the effect of a decompression stroke. The decompression stroke consists of an axial return stroke of the transport screw injecting the plasticated plastic into an injection mould. A design of this type allows undesired partial and structural colour changes in the finished injection moulding to be avoided. <IMAGE>

Granted: 1992-09-03
Abstract: The invention relates to a tyre inflator consisting of a receptacle sleeve (1) for a compressed gas cartridge (2) and an inflating head with an automatically closing valve and a hollow pin (5) to open the compressed gas cartridge. The receptacle sleeve has a casing connector section into which the inflating head can be screwed. The inflating head contains a flow channel connecting the valve with the hollow pin projecting into the interior of the receptacle sleeve and is under inflating pressure after the compressed gas cartridge has been opened. From the flow channel opens a transverse bore (8) in which a safety element (9) loaded by a return spring and sealed against the transverse bore is guided in the manner of a piston. A safety recess (13) on the casing connector section is allocated to the safety element. The inflating pressure causes the safety element to move against the action of the return spring and thus to engage positively into the safety recess of the receptacle sleeve screwed on the inflating head.

The areas (4' and/or 5') not covered by the laminate stack have a protective mask (6) to prevent them from meeting when the press is closed. ADVANTAGE - The caul enables different size laminates to be produced (within the dimensions of the cauls in the press) without causing damage to the areas of caul not used in the pressing operation. Low cost simple production of the caul.

Inventor: BECK MARTIN
IPC: H01F13/00
Filed: 1992-11-07
Granted: 1993-09-30
Abstract: The invention assumes that the envelope of a decreasing alternating magnetic field for demagnetizing magnetic materials must be larger than can be achieved by conventional oscillating circuits. Accordingly, a gradually decreasing alternating magnetic field having a large decay factor is generated in an oscillating circuit (C1, L1, L2) in whose air-core coil (L1) the material is held. By specifically recharging the capacitor (C1) from a recharging capacitor (C2) by means of a power supply (LS2), the capacitor voltage (U1) is increased and the energy which is reduced by damping is resupplied synchronously with the oscillation process, so that the envelope E(t) of the alternating field is specifically enlarged and the duration of the decaying alternating magnetic field in the air-core coil (C1) is prolonged. <IMAGE>
