Title: Improvements in or relating to telephone systems
IPC: H04Q3/42
Filed: 1961-07-19
Abstract: 948,386. Automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 19, 1961 [July 22, 1960], No. 26164/61. Heading H4K. Coupling between circuits linked by the small aperture of a transfluxor in a subscriber's line circuit indicates the calling condition of the line, the establishment of a speech path removing the coupling which is not restored when the speech path is broken by the called subscriber. By this means the offhook condition of a calling subscriber is distinguished from the off-hook condition of a subscriber on the point of hanging up. In Fig. 3, the transfluxor TF, shown as two circles, is constantly under bias by a winding d3 so that the smaller aperture has no coupling between an interregating pulse source PG driving winding d4 and the output windings d5, d6. When, with an off-hook condition, the subscriber's loop is closed transistor T3 conducts and winding d2 is energized to set the transfluxor by switching its inner band and thereby coupling the interrogating pulses PG to the outputs. Output d6 marks the position of the line circuit in its group by a multiple M12 and output d5 marks the group for the benefit of a controller VBS which connects the calling line by switching transistor T1 in a matrix SN. Current is now drawn by transfluxor winding d1 which augments winding d2 and fully reverses the transfluxor. Coupling between pulses PG and the outputs is now removed. The speech path is set up in response to digits which select terminals such as T1 to T10 and break down a second transistor in the matrix such as T2. When the speech path is released by the called party, winding d1 is no longer energized but, if the calling subscriber stays off-hook, winding d2 is still energized and the transfluxor is not reset. Even though the offhook condition is present, therefore, the interrogation pulses PG are uncoupled and a calling condition is not signalled. At a called subscriber's line circuit the winding d1 is energized first during a call and fully reverses the transfluxor's state so that no calling condition arises at any time. Once the on-hook condition is resumed, bias on winding d3 resets the transfluxor.

Abstract: 425,837. Production of high voltages. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin) Sept. 22, 1933, No. 26194. Convention date, Sept. 23, 1932. [Class 38 (iv)] An arrangement for producing a high unidirectional voltage comprises a moving endless insulating band or wheel 5 carrying condensers 6 which are charged individually from one or more D.C. sources 2, 10 and are discharged in series through the load circuit 11. The negative pole of the source 2 may be earthed and the positive pole of source 10 may be connected to the charge collector 9 when the source 10 may be supplied from a D.C. generator driven by the band 5 through the wheel 4 the band 5 being driven through the wheel 3. To avoid the energy losses caused by reversal of the polarity of the condensers when passing the source 10, switching devices, which may operate by gravity, may be arranged to -reverse the condenser connections, Fig. 4, (not shown), at this point. If the condensers 6 are not arranged along the whole of the band or wheel 5 the apparatus produces recurring impulses of unidirectional high voltage. Auxiliary devices such as choking coils, condensers or resistances may be provided to suppress electric oscillations. The Specification gives dimensions of an apparatus of this type for obtaining a particular voltage. The Specification as open to inspection under Sect. 91 stated that charging could be effected using an A.C. source. This subjectmatter does not appear in the Specification as accepted.

Title: Vacuum tube control for solenoid actuated mechanism
IPC: B07C5/36
Filed: 1958-08-18
Abstract: 863,948. Valve relay circuits. MANDREL INDUSTRIES Inc. Aug. 18, 1958 [March 14, 1958], No. 26537/58. Class 40(6) [Also in Group XL(b)] A magnetic armature control circuit comprises a non-gaseous valve 35, rendered conductive by a positive-pulse on the grid so that capacitor 62 is substantially discharged, the inductance of the solenoid 25 being sufficiently high as to pass negligible current during the pulse, capacitor 62 being recharged via the solenoid 25 at the end of the pulse to actuate the armature 61. In a photo-electric sorting machine (see Group XL(b)) a voltage pulse is fed from the amplifier 42 to the writing brushes 47, 48 of a commutator delay system 43, synchronized with the rotation of the machine. The pulse is stored in one of the capacitors 46 until the rotor contacts reach the reading brushes 49, 50, which partly discharge the capacitor 46 into the transformer 54. This provides a -positive pulse at the grid of valve 35, the negative being suppressed by the diode 57. The discharge is completed by short circuiting brushes 51, 52. The valve 35 is normally passing low current so that capacitor 62 is charged. On receipt of a short positive pulse from transformer 54, the valve 35 partially discharges capacitor 62 but negligible current is built up in the inductance of the solenoid 25 until the end of the pulse when the capacitor 62 recharges through the solenoid 25. This displaces the armature 61 carrying a hammer 22 for a predetermined period. The duration of the thrust on the armature 61 is adjustable by variation of the natural frequency of the variable capacitor 62 and the inductance of solenoid 25. The amplitude of thrust is adjustable by the grid bias control 59.

Filed: 1928-09-17
Abstract: 297,326. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts Ges.). Sept. 17, 1927, [Convention date]. Drawings to Specification. Master control systems.-In a multiple-unit control system for the motors of electric trains, where step-by-step controllers on separate coaches are required to follow the movement of a controller on the driver's coach, each controller including the driver's controller is provided with a step-by-step actuating device depending on successive energizations and de-energizations of an electromagnet. The driver's controller is first turned manually to any selected position without affecting the distant controllers and independently of its electromagnetic actuating device. When released the driver's controller is turned back step-by-step by its actuating device, and the movements of the other controllers, under the action of their respective electromagnetic devices, take place in corresponding steps. The extent of the original manual movement of the driver's controller determines the number of steps which each controller will subsequently execute under the action of its electromagnetic device. The electromagnets may open and close valves of compressed air cylinders which actuate the controllers. The follow-up control circuits include a threewinding notching relay, which also serves as a current-limit relay.

Abstract: 1306418 Separating the components of a binary liquid mixture by distillation DAICEL Ltd 3 June 1970 [6 June 1969] 26767/70 Heading BIB A solution of two liquids A and B, which have a small difference of volatility and/or which form an azeotrope, is separated by adding a third liquid C, which is soluble in A but insoluble in B, to obtain a single-phase mixture containing at least 20%, preferably 50 to 70% by weight of C; and submitting the mixture to partial evaporation so that vapour flows, without fractionation, to a condenser. The evaporation may be effected by heating the mixture, or by bubbling a gas through it, or by leaving it to stand in the open air. The condensate comprises liquid B (together with some A and C); and the liquid remaining in the evaporator comprises liquids A and C, free from B. In the apparatus shown, the solution to be separated, supplied through conduit 9 to vessel 1, is mixed with liquid C; and the mixture is passed through heater 6 into the top of distillation column 2 where vapour is evolved, either by heating the column or by blowing nitrogen gas into the bottom thereof. The vapour flows to condenser 7, and the condensate is mixed with liquid C in vessel 3 in order to cause liquid B to separate out; the two phases are separated in decanter 4. The liquid withdrawn from the base of column 2 is mixed with the (A+C) layer from decanter 4, and the mixture is passed to distillation column 5, where A is separated overhead. Liquid C, withdrawn from the base of column 5, is returned to vessels 1 and 3. The use of added water in the separation of the following pairs of liquids is exemplified:- (a) methanol and styrene (b) glacial acetic acid and toluene (c) acetone and hexane.
