Abstract: 667,752. Clutches. BRITISH THOMSONHOUSTON CO., Ltd. April 25, 1950 [May 7, 1949], No. 10170/50. Class 80 (ii). In a clutch wherein torque is transmitted between magnetic plates 25, 29 mounted in a chamber 14 through finely-divided magnetic particles suspended in a fluid contained in the chamber when a magnetic field is created in the gap 32 between the plates by energisation of an electromagnet coil 35 in one of the plates, viscous drag between the plates when the coil is de-energised is prevented by effecting the transfer of the fluid to a storage chamber 48, from which it is returned to the chamber 14, when energisation of the coil is again required, under the control of a valve 53. Fluid in the chamber 14 is thrown centrifugally through a passage 49 into the chamber 48, leading through a passage controlled by the valve 53 into a chamber 15 communicating with the gap 32 through passages 59 in the plate 25, but fluid is retained in the gap 32 so long as the coil 35.is energised. When the coil is de-energised, valve 53 is closed, so that substantially all the fluid in chamber 14 is transferred to chamber 48. The valve is opened prior to reenergisation of the coil, and may again be closed after the clutch has engaged.

Abstract: 542,729. Washing granular material. UNIFLOC REAGENTS, Ltd., and SAMUEL, J. O. June 17, 1940, No. 10497. [Class 82 (ii)] In an apparatus for washing sand, gravel &c. a feed vessel B into which the mixture of sand &c. and water is fed by a pipe S, is connected to a washing vessel A by a conduit C. A shaft M driven by a motor O is rotatably mounted on the three vessels and has mounted thereon at least one impeller G and also a spinner E provided with a serrated upper edge. Secured to the lower edge of an adjustable frusto-conical base Z embracing the lower end of the vessel C is an annular plate D provided with two annular sets of pegs X and another impeller F is mounted on the shaft M below the spinner E. In use, the sand &c. mixed with water is fed into the vessel B, the vessel A being full of water and the spindle M revolving at high speed. When the spinner E gets up to speed, the water is forced by the blade of the impeller G against the sides of the conduit C and rises in the vessel B. As the sand continues to enter the conduit C it is retained by centrifugal action until the head of sand exceeds a certain figure when it discharges into the spinner E. The sand is then thrown violently and upwardly between the pegs X and finally washed sand settles and passes out through the outlet Y; the fines and impurities overflow at H. The rate at which water is passed through the apparatus may be controlled so that the amount of the suspended matter in the effluent is for example between 0.3 and 1 lb. per gallon as referred to in Specification 450,032 and is flocculated by the process described in Specification 435,126, [Group I], or by the use of flocculating gels produced as described in Specification 5'16,294, [Group I], the clarified water being returned to the washing apparatus. A small amount of deflocculating agent may be added to the washing water before use.

Title: Improvements in electrical signalling systems
IPC: H04Q3/62
Filed: 1943-07-08
Abstract: 566,779. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., BAKER, G. T., and TAYLOR, R. July 8, 1943, No. 11075. [Class 40 (iv)] A selector is started by a subscriber who receives an audible signal at each step and stops it in the appropriate position. In the ten-line P.A.X. shown, the subscribers have voice-powered transmitters and a key PB1 on the hand-set for bridging the line wires. A call is initiated by operating this key, whereupon line relay C steps the forward-drive switch SS one step off normal and so energizes H. The key is then released, C falls and H holds momentarily over pulse wire IPL and then connects this wire to the stepping magnet SSM over the off-normal bank. At each step, a tone signal is given from wire ITL which receives pulses of tone current synchronous with the driving pulses on IPL from a neon tube generator. When the switch has made the desired number of steps, the key is operated again and C pulls up to stop it. If the line is idle, H pulls up also over the zero contact of the wanted line in series with H of the wanted circuit and the latter connects up calling tone from CTL. When the subscriber replies, his relay C moves his switch one step off-normal to cut off the calling tone. If the line is busy, H is unoperated and the caller continues to hear the tone signals. At the end of a conversation or when the call is abandoned, the key contacts are opened again and the switch is stepped on to its home position. It can be stopped if desired before reaching this position by re-operating the key. One of the switch positions may be devoted to a conference circuit. Subscribers are given the facility of breaking in on busy lines by bridging their h3 contacts. A non-linear resistance shunt, e.g. a dry rectifier, may be put across the receiver to prevent its actuation by the calling tone, the calling signal in this case being given out by the transmitter. In a modification, the key contacts PB1 are replaced by cradle switch contacts and a further switch on the hand-set with its contacts normally closed is used to give the temporary interruption necessary to drive the switch to the wanted line. The invention is stated to be applicable to larger systems.
