Title: Multiple contact electric switches
IPC: H01H15/02
Filed: 1970-12-16
Abstract: 1340188 Mechanical switches CTS CORP 16 Dec 1970 [17 Dec 1969] 59611/70 Heading H1N An electric switch comprises fixed contacts 27, 28, a moving contact bridge 32 carried by a contact carrier 31 and a slider 16 having a handle 17 projecting through slot 18 in the cover and two legs 19 projecting into the two ends of slot 36 in carrier 31, slot 36 also containing compression spring 37. Projections 41 on carrier 31 project into notches 15, 15a, 15b, 15c as appropriate in the cover and two cams 22 having sloping cam surfaces 23 on slider 16 project into two slots 38 having sloping ends 39 in carrier 31. Detent spring 24 having detents 25 fits over shoulder 21 on slider 16, detents 25 locating in the same pair of notches 15, 15a, 15b, 15c, as projections 41. The operation is as follows. Assume projections 41 and detents 25 are located in notches 15a. If slider 16 is moved to the left, detents 25 come out of notches 15a but projections 41 remain therein. As slider 16 moves to the left, the right hand leg 19 compresses spring 37 and cams 22 move along slots 38 until cam surfaces 23 engage the sloping ends 39 of slots 38 and depress the left hand end of carrier 31 so that the left hand ends of projections 41 come out of notches 15a and carrier 31 is snapped to the left by spring 37 until detents 25 and projections 41 engage the next pair of notches, 15b. Similarly when moving slider 16 to the right. Constant cleaning occurs when the cams 22 depress the end of carrier 31 causing the ends 32a of moving contact 32 to spread out and wipe over the fixed contacts 27, 28.

Patent GB-2012526-A (GB)
Title: Digital transmission substitution systems
IPC: H04B1/74
Filed: 1978-11-29
Abstract: The invention relates to digital transmission substitution systems in which a digital communications connection can be transferred from a fault system to a correctly operating substitute system. When substitutions of this kind are to be effected, particularly in digital systems having a high bit transmission rate, the problem occurs of keeping the switchover time as short as possible so as to minimise disturbances in transmission. In addition there is the problem of avoiding the need for additional control lines between stations for the execution of the substitution. In a terminal station for such a system there is provided a selectively operated switching arrangement for effecting substitution and controlled by a control device arranged to transmit and receive via the substitute system information additional to the communications signal and indicative of, and providing control of, the substitution. The control device is activated in the event of a fault signal being emitted by a line terminal device. <IMAGE>

Title: Capacitive Measuring System with Automatic Calibration Means
IPC: G01R27/26
Filed: 1979-04-20
Abstract: In a device for continuously monitoring the denier of a moving yarn filament, by passing the filament through a capacitive sensor 12B to develop an electrical signal representing an absolute measurement of the filament with reference to a prescribed datum, signal drift arising from contamination of the capacitive sensor is obviated by developing compensating signals to be combined with the filament measurement signal. The compensating signals are developed in circuit (20B), including an auto-zero circuit and an auto-gain circuit, which receives the measurement signal from the capacitive sensor. While the sensor is vacant, the auto-zero circuit digitally counts at 78 clock pulses to generate a digital output, converts the digital output into a corresponding analog signal (80) detects a prescribed comparison at 84 between the analog signal and the measurement signal, and stops the count at a zero compensating value when the comparison is detected. Then, the auto-gain circuit applies an unbalanced drive to the sensor by closing switch 92, digitally counts at 98 clock pulses to generate a digital output, and varies the measurement signal gain at 100 with the digital output. When a prescribed comparison at 104 between the gain- adjusted measurement signal and a standardized output signal is detected, the count is stopped. <IMAGE>

Title: An improved method of producing a fibrous mass from peat and means for carrying out the method
IPC: C10F7/00
Filed: 1979-07-27
Abstract: The present invention relates to a method of producing a fibrous mass from peat. It has not been possible in the past to produce an easily dewaterable fibrous mass from peat when using in the production a continuous process which (1) could be carried out with a minimum amount of manpower, (2) enables a higher yield from the peat moors than had been the case before, (3) enables an efficient separation of colloids and particles smaller than 0.2 mm, and (4) dt enables the use of a simple equipment which, by a quickly made replacement of a screening member, can be changed to match the nature of the dug-up peat. The object of the present invention was to obviate this problem which, according to the invention, is realised substantially by the features that, after a primary sorting operation, the peat-material suspension is liquid-concentration regulated by supplying thereto an amount of liquid depending on the degree of humification of the dug-up peat, and then supplying the suspension under pressure to at least one screening member having a permeability depending on the peat-fibre concentration of the peat-material after said concentration regulation.

Title: Method and apparatus for isolating and separating fibres
IPC: D01H4/30
Filed: 1979-08-02
Abstract: In a method for isolating fibres of a fibrous material, pinching and separation of fibres is effected in such a manner that the pinching action is simultaneously applied to fibres spaced a certain distance from one another. Simultaneously, the velocity of flow of fibrous material is substantially increased so that individual fibres are pulled out. An apparatus for carrying out the method has an outlet pair of rolls between which the fibres are pinched. One roll 5 has a profiled surface with projections 9 which, together with the flat surface of the other roll 4, grip individual fibres. The projections are formed by intersecting oppositely sloping helical grooves. <IMAGE>
