Title: Formation of grooves in monofilament slide fastener members - using an unheated press tool and subsequent thermo-fixing
IPC: B29D5/04
Filed: 1978-02-10
Abstract: Formation of grooves for sewing threads in rows of slide fastener members of plastic monofilament which have pairs of legs lying one on top of the other, is described. The fastener members are held in contoured hollows whilst an unheated press tool presses the upper leg into contact with the lower leg, and simultaneously deforms the upper leg to produce sewing thread grooves. The deformation speed is related to, but less than, the relaxation speed fo the material. The rows of members subsequently undergo a thermofixation process by means of hot air, infra-red radiation or ultrasonic vibration, which is confined to the region of the impressed sewing grooves. Smooth, deep groves are produced which protect sewing threads from abrasion but which do not reduce the strength of the fastener members.

Title: Mat for dry-pressed esp. cellulosic article prodn. - contg. dense pre-strengthened central layer having low moisture content
Inventor: KISS GUENTER H
IPC: B32B7/09
Filed: 1979-11-19
Abstract: Mat for mfg. pressed articles in a dry process consists of a pre-strengthened layer of opt. powdered aggregate-contg. cellulose- and/or lignocellulose fibres, the layer being solidly bonded to workable corrugated support layers. Novelty consists in using a pre-strengthened central layer the density of which, before pressing, approximates to its density in the finished article. Central layer moisture content is less than 10%. The central layer can consist of at least one layer of thermoplastic- or thermosetting binder-impregnated (1) corrugated paper or cardboard or (2) pleated fabric or crinkled fleece, or is (3) a thermoplastic filled and/or reinforced esp. with cellulose- or lignocellulose materials. The central layer can also be a laminate of one or more materials (1)-(3). Central layer bonding is achieved by sewing or stitching, pref. using thermoplastic material threads, or by needling, or by cementing with heat-softenable adhesives. At least some of the central layer materials are recycle materials. Low moisture content shortens pressing time and prevents steam blister formation. Density control prevents moisture absorption during storage. Mats contg. compacted central layers are less bulky and require less storage space.

Title: Beam deflection current linearising coil for TV receiver - has ferrite case to limit stray flux from permanent magnet
Inventor: SCHNELLER ANTON ING GRAD
IPC: H01F17/04
Filed: 1979-12-20
Abstract: The construction of the current linearising choke is intended to screen neighbouring parts of the receiver from high intensity magnetic fields and to reduce the amount of permanent magnet material required for premagnetising the core. The coil (2) is wound onto a bobbin shaped ferrite core (1) in the normal manner, and terminated in connector pins in a base (4). The permanent magnet (3) for premagnetising is mounted on the top flange of the core (1). A cover of ferrite, or similar material with high magnetic properties, (5) is placed over the magnet (3) and coil assembly (1,2,3). Its open end is near the bottom flange of the core (1). By thus closing the return path for the coil and magnet flux stray leakage is greatly reduced. The reduction in reluctance results in less permanent magnet material being required for the same flux.
