Patent CH-650080-A5 (CH)
Title: Device for indicating the distance of a vehicle with respect to an obstacle
Inventor: TOUBOUL ALBERT
IPC: G01S17/931
Filed: 1981-05-19
Abstract: The device comprises two infrared emission diodes (4) powered by a frequency generator (2). These diodes (4) are located on either side of a receiving photo-diode (6) and the infrared beams which they emit converge in the axis of the receiving photo-diode (6) at a predetermined distance. If these beams strike an obstacle (5) at their point of convergence, they are reflected on to the receiving photo-diode (6) which transmits a visible or audible signal to a signalling device (10). Such a device, mounted at the rear of a vehicle, allows indication of its distance from another vehicle during parking manoeuvres. <IMAGE>

Title: Process for producing heat-insulated ceiling/wall transitions by means of a shuttering insert, using concrete as the building material for ceiling and wall
Inventor: ZUMBRUNN ALFRED
IPC: E04B5/00
Filed: 1982-12-15
Abstract: The process for producing heat-insulated ceiling/wall transitions consists in that a shuttering insert (1, 2, 3), comprising a displacement body (1), a heat-insulating layer (2) and an elastomeric material (3), is laid, level with the ceiling (D), on the inner wall shuttering (WS), in that the wall (W) is filled with concrete up to the region of the upper side of the ceiling, and the displacement body (1) of the shuttering insert is then removed, together with the wall shuttering (WS), in order to form a niche as bearing for the ceiling (D) which is to be produced. In contrast, the heat-insulating layer (2) of the shuttering insert remains in the wall (W) in order to provide heat insulation between ceiling (D) and wall (W). <IMAGE>

Patent CH-660100-A5 (CH)
Inventor: HARTWIG CARL SVERKER MAGNUSSON
IPC: G05D16/20
Filed: 1981-12-18
Abstract: A compressor drive system for controlling the gas pressure in a pressure gas volume (106) connected to the compressor (101). A brushless alternating current motor (23) is directly coupled to the compressor, which is driven with the same speed as the motor. The pressure in the gas volume (106) is sensed by pressure sensing means (109) connected to a converter (114). The converter simultaneously changes the amplitude and frequency of the drive voltage supplied to the motor (23). This is done in response to pressure changes in volume (106). The motor is stopped if the pressure exceeds a preset maximum value. A pressure gas container (104) is depressurized at motor stop to allow restarting without counter pressure on the compressor. Means (44) for controlling the amplitude and frequency of the drive voltage is provided so that the normal speed maximum load current is never exceeded during motor start.

Title: A composition comprising polypyrrolidone and iodine which exhibits a biocidal activity
Inventor: BARNES CARL EDMUND
IPC: C08G69/48
Filed: 1978-08-25
Abstract: A novel complex of polypyrrolidone, also known as nylon 4, and iodine is described. The complex material has biocidal properties in that it demonstrates the specific, fungicidal and bactericidal effects of free iodine, but without indicating its side effects, such as skin irritation and other toxic properties. The complex can be formed from pyrrolidone in a wide variety of physical and dimensional forms. The novel material can be used to produce textiles, which are in turn advantageously converted into bandage materials. Even in dry powder form, it can be used for the preparation of salves and creams, which are important in particular for topical application in therapeutic treatments.

Title: Polishing disc assembly for metallurgical samples - has sandwich constructed support plate for embedded abrasive
IPC: B24D9/00
Filed: 1972-12-14
Granted: 1974-11-08
Abstract: A polishing disc for metallurgical work which can be used with any know abrasive, has a metallic backing plate with a natural or synthetic fabric attached to it by glue. The metallic plate is itself preferable made in laminated form, having a thin layer of metal behind the fabric and this is stiffened and supported by a thermosetting resin layer.

IPC: C08F20/54
Filed: 1979-12-21
Abstract: The invention relates to a process for the preparation of  alpha , beta -unsaturated N-substituted carboxylic acid amides, novel  alpha , beta -unsaturated N-substituted carboxylic acid amides, a process for the polymerization of these novel  alpha , beta -unsaturated N-substituted carboxylic acid amides, including the polymers, and the use of these polymers as sedimentation, flocculating, dewatering and retention aids, as additives for mineral oils, and as ion exchangers. The  alpha , beta -unsaturated N-substituted carboxylic acid amides are prepared by transamidation of  beta -hydroxy or  beta -alkoxy carboxylic acid amides with primary amines and heating of the N-substituted  beta -hydroxy or  beta -alkoxy carboxylic acid amides obtained as intermediate products in the vapor phase in the presence of catalysts. Primary amines are preferably used in the conversion which have no hydrogen beta to the amino group. These  alpha , beta -unsaturated carboxylic acid amides may be neutralized and/or quaternized and polymerized by processes which as such are known alone or with other comonomers, and preferably acrylic or methacrylic acid derivatives such as acrylamide, to give cationic polymers. These polymers are suited for use as flocculating and sedimentation aids, as dewatering and retention aids in papermaking, as additives for mineral oils, and as ion exchangers.
