Patent DE-2848861-A1 (DE)
Title: Mould for continuous slab casting - having downwardly extended side walls through which water is supplied onto the slab
Inventor: GLADWIN FLOYD R
IPC: B22D11/055
Filed: 1978-11-10
Abstract: The mould body consists of front and gear walls and a pair of side walls, each side wall comprising an inner mould-forming plate and an outer backing plate. Depending downwardly for a considerable distance from each side plate is an extension plate having an inner face contacting the cast slab and forming a co-planar extension of teh side plate. The extension plate also incorporates a back plate including a hollow recess which is closed by the face plate, the recess being supplied with cooling fluid which is discharged through holes in the face plate onto the edge of teh cast slab. Near the bottom edge of the mould a horizontal groove extends across the width of the inner surface of the face plate to prevent coolant flowing upwardly into the mould. The extensions provide additional support against distortion and rupture of the thin skin of teh casting leaving the mould, and provide additional cooling.

Title: Draw-frame sliver false-twist device - to improve sliver consolidation and permit higher output speeds
Inventor: SCHMID REINHOLD
IPC: D01H5/28
Filed: 1978-11-16
Abstract: A draw frame lap condenser apparatus contains, between the delivery rollers and the calender rolls, a pre-condenser trumpet to form the lap into a sliver, a twisting device which imparts false twist to the sliver, and a sliver trumpet which feeds the sliver to the calender rolls. The twisting device consists of a hollow cylindrical body with internal recesses or projections, preferably a spiral slot in the inner wall, which is rotatable by means of a driving belt passing around the outside of the body and around two traction rollers which increase the wrap angle of the belt around the body. False twist improves the consolidation of the sliver, giving it greater strength and abrasion resistance, and enables higher delivery speeds to be employed. The vol. of the sliver is reduced, giving an increased sliver-can capacity.

Title: Lubrication system for refrigerator compressor - uses refrigerant depleted solvent liquid for lubrication of screw compressor
Inventor: NAJORK HELMUT DR ING
IPC: F25B25/02
Filed: 1978-11-21
Abstract: The compressor based refrigerator is operated with refrigerant and solvent circulated in the system. Lubricant is not mixed with the refrigerant and solvent. The evaporator works as a degasser and the condenser acts as a reabsorber. Depleted solution flows from the evaporator through a pipe (6) to the compressor (3) inlet. This solution is used as the compressor lubricant. A screw compressor is used which compresses the refrigerant vapour and pumps the liq. solvent.

Title: Broad slot nozzle for extruding films and laminates - has separately-fed channels delivering bond to edge zones
Inventor: KOENIG ULRICH DIPL CHEM DR
IPC: B29C48/08
Filed: 1978-12-01
Abstract: Feeding channels for a thermoplastic which imparts adhesion, extend in an extrusion nozzle body from connecting bushes on its outer surface to the edge zones of the nozzle slot. The nozzle is a broad slot nozzle for the extruding of films and laminate materials, the surfaces of the edges of which are coated and/or enveloped with additional material. Between the two parts forming the nozzle body, there is at least one distribution chamber connecting to the nozzle slot. Overcomes the difficulties arising when already extruded films are laminated and oxidation takes place, as well as the tendency of co-extruded films to develop ripples and cloudiness, as well as to separate after extrusion. The process and equipment simplifies the prodn. of edging surface coated films and laminates so that incompatible polymers can be edge-bonded satisfactorily. The equipment is of simple design easily handled and cleaned. Laminates are produced from homo- and co-polymers of ethylene, propylene, styrol, polyesters, polyanides, etc. The bonding materials are thermoplastics of various molecular structures.

Title: Sewing machine adaptor has guides and mounting holes in bed - to hold sliding plates and adaptor to give single and double needle working
Inventor: PAPAJEWSKI REINHOLD
IPC: D05B57/26
Filed: 1979-09-26
Abstract: The stitch plate adaptor, to convert a single-needle industrial sewing machine into a double-needle machine, has two pairs of parallel guides in the bed opening, for sliding plates to cover the mountings for two loopers. The surface of the sliding plates is level with the bed. There are two carrier bars below the upper surface of the bed, and a third pair of parallel guides run across the line of the other guides, to hold an adaptor at the end of any stitch plate type to be held in a number of positions, according to stitch plate type. A third sliding plate rides on the third parallel guides to shroud the first adaptor, with its upper surface level with the upper surface of the bed. A second adaptor has an adaptor rod for the first or second carrier bar, carrying the other end of the stitch plate from that against the first adaptor. The design allows a sewing machine bed to be used with a single or a double needle machine.

Title: Deactivator circuit for security strip on saleable goods - has deactivating coil pulsed from thyristor controlled capacitor discharge
Inventor: REITER WERNER A
IPC: G08B13/24
Filed: 1980-04-16
Abstract: The deactivator circuit consists of a transformer (7) which, via a rectifier (8) and a resistor (9), feeds the oscillatory circuit, made up of the deactivating coil (3) and a capacitor (10). The deactivating coil (3) is in series with a thyristor (11), the gate of which, is fed via two microswitches (12,13) from one side of the circuit rectifier (8). When those microswitches (12,13) which are in series are closed, a magnetic field builds up in the deactivating coil (3) in less than a millisecond, due to the discharge pulse of the capacitor (10). Thus, sharply defined magnetic zones arise, which cannot be changed by incorrect use of the deactivator. Other models of strip deactivator can be constructed for books, records, music cassettes etc., where in the case of the latter, the form is such, that the recording on the tape itself is not damaged during deactivation of the strip.
