Title: Automatic control unit for record player arm - uses several bimetallic elements each with control winding
IPC: G11B3/085
Filed: 1975-05-22
Abstract: The control unit, for a record player arm, is used ot automatically control the movement of the arm and employs a number of bimetallic elements each with a control winding. The contraction of each bimetallic element provides a mechanical displacement of the arm. One or more bimetallic elements are provided for the raising of the arm, the angular positioning of the arm in accordance with the record diameter and the return of the arm to its support at the end of the record. Three bimetallic elements may be used for angular positioning of the arm, with one bimetallic element for the return of the arm and one for raising the arm.

Title: Domestic refuse compactor - has drive motor with switching system for pole change and short circuiting to prevent overrunning
IPC: B30B9/30
Filed: 1975-06-27
Abstract: Domestic refuse compactor has a ram driven by an electric motor via a reduction gear. The ram immersed into the container accommodating the refuse, is reversed by the drive motor. On its return to the starting position the ram pushes against a flexible element for braking the drive motor which has been previously switched off by a limit switch. The overrun caused by the inertia after the motor has been switched off is eliminated so that no excessive stresses are built up in the ram drive. The drive motor has a switching circuit which ensures that after the limit switch has been opened the motor polarity is changed and it is short circuited. This effect brakes the drive motor within a very short time and hence limits the overrun of the compacting ram to a minimum value.

Title: Nitrile resin-PVC blends for coating lightweight gloves - to obtain flexible impermeable gloves without stitching
IPC: D06N7/00
Filed: 1975-11-21
Abstract: One face of a lightweight fabric is coated with a compsn. based on a nitrile polymer but contg. a minor proportion of PVC and soap. The coating is applied as a foam to an unsupported portion of the fabric, using a doctor knife to control the thickness, but without forcing the coating to penetrate the fabric fully. The coating is gelled and the layers of coated fabric are superimposed with the coated faces in contact. Profiled press tools are then used to weld and cut out the glove profiles. The glove forms are inverted and mounted on a former, so that the coated faces are outside, before dip coating the gloves to apply an impermeable rubber or plastic coating over the foam coating. The gloves are for domestic or industrial use. They are relatively flexible because of use of a lightweight fabric without fully permeating the fabric. The presence of some PVC in the substrate coating allows the layers to be welded together, avoiding stiching.

Title: Fibrous material with low water-soluble fraction prodn. - using deionised water wash, centrifuging and drying cycles, avoiding corrosion
Inventor: GARCIA D SANTOS
IPC: C03C25/00
Filed: 1976-01-26
Abstract: The recovery of materials with a low content of soluble elements, with numerous possible applications, comprises subjecting the prod., in at least one phase of the synthesis process of these elements, to treatment with deionised water in a suitable vessel, followed by discharge and then drying. The cycle is repeated, according to the number of max. desired soluble elements. The process is suitable for the treatment of materials of all kinds, e.g. fibres, blankets, filaments, fabrics, felts etc. based on fibres, e.g. rock wool, asbestos etc. and generally prods. with similar characteristics, which are used for insulation and sealing purposes etc. The removal of the soluble elements prevents corrosion, e.g. chloride ion stress-corrosion cracking, of adjacent metal parts when these materials are in contact with water. Elements fulfilling the highest safety requirements for each individual case can be produced in this way.

Title: Control system for distance of e.g. welding torch from moving surface - compares wavelengths of emitted and reflected hyperfrequency waves
IPC: B23Q15/24
Filed: 1976-12-09
Abstract: In the control of the distance of an object from a moving surface from which hyperfrequency waves are reflected, a radiation director is disposed opposite the surface, the director supplying hyperfrequency waves ad being fixed in respect to the objecT. Simultaneously radiation reflected from the surface is received by the director and the phase of the emitted wave is compared with that of the reflected wave.
