Patent CH-598116-A5 (CH)
Title: Electronic thread breakage detector - uses capacitor charge time as parameter for thread speed and cut-off delay
Inventor: GITH WALTER
IPC: B65H63/06
Filed: 1977-01-26
Abstract: An electronic thread breakage detector cuts off a textile machine whenever a set response parameter is not maintained for a certain period. The cut-off time is varied inversely proportional to the thread speed. The instantaneous charge of a capacitor is used as a parameter for the thread speed. The time required for an additional charge of the capacitor up to a set value is used as a parameter for the cut-off time. This prevents malfunction of the detector at very slow thread speeds when the stored energy is so small that a broken thread may be erroneously simulated.

Patent CH-622117-A5 (CH)
Title: Display device on a traffic-signal or barrier installation
Inventor: MEIER BERNHARD
IPC: G08G1/096
Filed: 1980-05-05
Abstract: The time signal for traffic-signal installations informs the road-user about the remaining period of the red-light phase. A large time-display board (4) attached next to the red light is connected to the timer of the red light and is controlled by the latter. The seconds display motivates the motor-vehicle driver to switch the engine off while waiting at the red light. By this means, energy is saved and the environment protected. <IMAGE>

Patent CH-681920-A5 (CH)
Inventor: TIEFENTHALER KURT DR
IPC: G01N21/03
Filed: 1991-07-02
Abstract: The invention describes a process for the selective detection of substances in chemical, biochemical and biological measuring samples (13) by the determination of changes in the effective refractive index of an executed mode (16) with the aid of a grid coupler (10). The essential feature of the invention is that a grid (4) of the grid coupler (10) is illuminated by a fanshaped field of light (9), a mode (16) is excited and emitted virtually as a plane wave (17) owing to weak coupling, a position-sensitive detector (7) is in the light field (9) of a diffraction order and thus the shift in a bright spot of light (12) formed by the emitted light field (17) is measured.

Title: Optical assembly for liq. level signalling in reservoir - uses optical fibre to direct light onto ball in sensor mounted on float arm
Inventor: FALCO LUCIEN
IPC: G01F23/36
Filed: 1982-04-02
Abstract: Light from a source (22) is concentrated by a convergent lens (26) onto the input end (24) of an optical fibre (25). The light from the remote end (27) is directed onto a ball (29) inside a sensor (28) mounted on the arm of a float. The ball rolls on a V-shaped or contoured base so that as the arm inclines from its normal position the ball moves to one side where the light does not reflect from it. The reflected light from the ball passes along a second optical fibre (31) to a photoelectric detector. A common section of optical fibre (30) with a Y junction may be used in place of the two optical fibres entering the sensor. USE - Optical indication of liquid level in reservoir.

Patent CH-653508-A5 (CH)
Title: Hearing-aid
Inventor: MEYER SERGE EDUARD HECTOR
IPC: H03G3/20
Filed: 1981-04-28
Abstract: The speech signals generated by a microphone (11) are fed to the input of a pre-amplifier (12). The pre-amplifier has a control input (13). The degree of amplification of the pre-amplifier can be varied by feeding a control constant voltage to the control input. The amplified speech signals are fed to a power amplifier (15) via a volume control (14). An earphone (17) is connected to the output of the power amplifier via a limiter (16). One input of a subtraction stage (19) is connected to the input of the limiter, and another input is connected to the output of the limiter. The difference signal at the output of the subtraction stage is amplified by a control amplifier (20), and rectified by a rectifier (21). The rectified difference signal is fed to an integrator (22), which outputs a constant voltage control signal, which depends on the extent of the limitation of the speech signal fed to the earphone, for the pre-amplifier (12). If the sound level is limited, the hearing-aid described above generates a significantly lower non-linear distortion factor than hearing-aids with previously known peak power. <IMAGE>

Title: Method for magnetohydrodynamic generation of electrical energy in an MHD generator which is driven using fuel
Inventor: DARDAI PAL
IPC: H02K44/08
Filed: 1977-03-11
Abstract: In the case of the method, the fuel is burned to form combustion products which are supplied, ionised by shock waves, to the MHD channel. In order to be able to use conventional fuels such as coal, oil, natural gas and carbon monoxide, etc., to keep the energy losses low and to achieve effective ionisation of the operating agent, the shock waves are not produced in the combustion chamber (10), by detonation of an explosive at point B, until the fuel has been burnt completely in said combustion chamber (10). In this case, the shock waves are passed a plurality of times through the combustion products by reflection on the walls (46, 48) of the combustion chamber. This produces multi-stage ionisation of the combustion products before said combustion products flow via the exhaust opening (34) to the MHD channel (12). <IMAGE>

Title: Spinning and twisting device on the ring carrier of a spinning or twisting machine
Inventor: MARZOLI ANGELO
IPC: D01H7/56
Filed: 1978-04-10
Abstract: The spinning or twisting device has a stator (1) and a rotor (11) linked by ball bearings (15) interposed between the stator and rotor in grooves (6, 14) suitably formed in the stator and rotor. An annular bracket (25) is provided under the annular cage (16) and the housings of the said cage for the ball bearings have edges (32, 33) suitably inclined so that when the spinning machine begins to rotate the cage (16) is raised, while as soon as the spindles stop the cage is lowered and is locked by friction against the bracket (25). In this way the rotor (11) stops at the instant when the spindles stop, and consequently the rotor body is prevented from drawing the yarn from the tubes by inertia. <IMAGE>

Title: Overturning protection bracket for tractor driver - has vertical members on tractor rear axle and which support horizontal telescopic member
IPC: B60R21/13
Filed: 1973-05-05
Abstract: The bracket system mounted on the tractor ensures that the driver is protected especially against the rolling when the vehicle overturns sideways on sloping ground. The horizontal connecting member is extended beyond the anchoring point of the vertical members so that the ends of the horizontal members reach into the external planes of the rear wheels. The vertical members 11 are bent outwards nd their upper ends are connected to the horizontal member 10. The horizontal member is connected to the upper end of vertical members at an acute angle. The horizontal member has hollow ends 101 in which slides a solid member 100. These members are connected by bolts 13. This arrangement ensures that the bracket arrangement can be adapted to the width of a particular make of tractor. On overturning the tractor comes to rest on the lane of its rear wheel and the brackets prevent further rolling. This action is augmented further by the digging in of the corner formed by brakcet members.

Title: Pushbutton protection switch with magnetic and thermal trip - allows bimetal strip to bend beyond contact operating point to prevent deformation
IPC: H01H73/56
Filed: 1974-06-13
Abstract: The push-button protection switch with magnetic and thermal trip allows the bimetal strip to bend a certain amount beyond its contact operating point to prevent changes in the switch characteristics due to the strip deformation. A two-arm lever (34) is pivoted on the armature (23) and has a restoring spring (37) acting on one end and passing through the extended end (38) of the armature. The opposite end of the lever is linked (33) to the free end of the bimetal strip (30) such that the lever is pressed against the armature, as the bimetal strip bends, and causes tripping of the switching members (8). As the bimetal strip continues to bend, the lever simply pivots (35) about the armature.
