Patent CH-657813-A5 (CH)
Title: Compressed-air brake device for rail vehicles
Inventor: SKACH KUNO
IPC: B60T15/24
Filed: 1983-03-18
Abstract: The compressed-air brake device for railway locomotives has a three-pressure brake control valve (5) with a main air line chamber (4) and a reference pressure chamber (7). A shut-off valve (3) which can be closed off as desired only below a pressure level in the main air line (1) corresponding to full braking is arranged in the connection from the main air line (1) to the main air line chamber (4). An actuable shut-off valve (22) and an overflow valve (20) are connected in series into a connection, which has a large cross-section and is provided in addition to a customary filling device for the reference pressure chamber (7), between the main air line chamber (4) and the reference pressure chamber (7), the overflow valve (20) closing when the pressure falls below a specific limit pressure level in the reference pressure chamber. A further actuable shut-off valve (17) monitors an enlargement of the through-flow cross-section of the release nozzle (13) of the three-pressure brake control valve (5). By actuating the shut-off valves, a normal mode of operation of the compressed air brake device, a subsequent braking valve effect, equalisation in the case of overloaded reference pressure chamber (7) and release of the brakes, when desired for emergency or forced braking, is possible. Leaks in the shut-off valves cannot give rise to a failure of the compressed-air brake device in this case. <IMAGE>

Patent CH-681864-A5 (CH)
Inventor: BLASER KURT
IPC: B23B51/10
Filed: 1990-08-16
Abstract: The special feature of a single-cutting edge countersink is that its shank (20) runs at a skew to the countersink head (1). In this arrangement, the centre line (X) of the shank intersects with the centre line (Z) of the head at the countersink point. The swarf groove (2) has a cutting edge (3) which can easily be resharpened several times because there is no relief on the cutting edge but a free running surface (4) which becomes a supporting surface (6). Resharpening is easy since in a first grinding pass the shank (20) is clamped so that the supporting surface (6) is enlarged at the expense of the free running surface (4). In a second pass the shoulder (11) of the countersink head running askew or eccentrically thereto is clamped and the free running surface is ground, thus once again producing a sharp cutting edge (3).
Patent CH-687957-A5 (CH)
Title: Dust=removal method from surface of moving material band
Inventor: SCHNEIDER ROBERT NICOLAS A
IPC: B08B5/02
Filed: 1994-09-06
Abstract: The dust particles are removed from the pref. stable strip material (1) by a contactless system. A blower (3a,3b) has an earthed potential surface (6) facing the surface of the strip and clear of it. The speed of the gas current from the blower is adjusted so that the critical charge resulting under Paschen's Law from the pressure and gap width is below the electrostatic charge of the particles on the strip surface. This causes neutralisation and overcomes the forces holding the particles on the strip. They are gathered up merely by the gas current, without the need for an ionisation unit consuming electric power, and extracted by an exhauster (7a,7b).

Title: Apparatus for slowing-down a laundry bag falling downwards in a laundry-discharge system
Inventor: RICHLI HANSRUEDI
IPC: E04F17/10
Filed: 1977-04-12
Abstract: This apparatus has a shaft pipe (3) which passes through all the storeys of a building, has an entry funnel (4) in each storey and ends in the cellar (2) of the building. In the cellar, the shaft pipe is adjoined by a braking pipe (6), the end of which is closed by means of a cover. The air in the braking pipe (6), in particular, is consequently compressed by the downwards-falling laundry bag, essentially filling the pipe cross-section, before it can rush past said laundry bag, with the result that the latter is slowed down by the air. When the laundry bag reaches the end of the slowing-down pipe, it actuates a switch which switches on a motor (15). By means of a threaded spindle (14) and draw rod (12), the motor opens the closure cover of the slowing-down pipe, so that the bag can fall out, and then closes it again. The apparatus is used primarily in hospitals and institutions where there is a large amount of laundry. <IMAGE>

Title: Device for fixing slot wedges for the attachment of electric windings in the longitudinal grooves of the magnetic core of an electric machine
Inventor: LESOKHIN ALBERT ZINOVIEVICH
IPC: H02K3/487
Filed: 1977-04-13
Abstract: At least one slot wedge (10) is disposed in the longitudinal groove of a stator, reciprocally interacting with a fixing wedge (19) which has teeth (23). The end (30) of the slot wedge (10) facing the fixing wedge (19) has a diagonal surface on which a corresponding diagonal surface lies on one end of the fixing wedge (19). A blocking clip (31) is provided which is mounted in the ventilation channel (32) of the stator (1). The parts of the blocking clip (31) running roughly parallel with the floor of the groove lie closely on the corresponding surfaces of the fixing wedge, while the side parts of the blocking clip are located at a distance from the side surfaces of the fixing wedge (19). A device of this type allows the re-tightening of the wedges which have become loose in the core groove of an electric machine to be carried out in simple fashion. Furthermore, it substantially reduces the weakening of the pressure on the winding due to the axial shift of the wedges and increases the operational reliability of the electric machine as a whole. <IMAGE>

Title: Process for the preparation of a product mixture comprising sulphurised, polyunsaturated fatty acids or triglycerides
Inventor: REVICI EMANUEL
IPC: C09F7/00
Filed: 1975-09-10
Abstract: To prepare a mixture of sulphurised, polyunsaturated fatty acids or triglycerides synthesised from such fatty acids, the same are mixed with an excess of sublimed sulphur and then kept with heating for an adequately long time with stirring at 90 to 130 DEG C to carry out the sulphur uptake. The mixture is then cooled to room temperature. Unreacted sulphur is either separated off or left in the liquid mixture. If the mixture is allowed to stand without separation of the unreacted sulphur, it additionally takes up further sulphur. Sulphurised, polyunsaturated product mixtures result which contain from 0.1 up to 2.5% by weight of sulphur. The polyunsaturated oil employed can be sesame oil. The sulphurised products of this type are used in capsules for the temporary interruption of the need for alcohol.
