Title: Improvements in or relating to subscription television computer
IPC: H04N7/167
Filed: 1956-10-22
Abstract: 834,442. Secret television. ZENITH RADIO CORPORATION. Oct. 22, 1956 [Nov. 14, 1955], No. 32083/56. Class 40 (3). [Also in Groups XV and XXXVII] In a subscription television system wherein a particular subscriber must set the positions of a number of decoding mechanisms at his receiver in a particular combination in order to receive a particular television programme, the settings are determined by a computer comprising programme selection means providing information representing the code condition of the decoding mechanisms necessary to decode the required programme, decoder identification means providing information representing the relationship between the operative positions and the code conditions of the decoding mechanisms, and control apparatus responsive to information from both means which determines the setting positions for the decoding mechanisms. In a subscription television service a six-digit identification number is allotted to each subscriber and a two-digit number to each programme, and on request a subscriber is supplied with the settings for knobs 16-20, applicable to that one receiver only, to enable him to see a particular programme. The knob settings are obtained by an operator by depressing those keys on the keyboard of a computer (not shown), which correspond to the subscriber's number and the programme number. Knobs 16-19 position cam discs 11b- 14b and 12a-15a, knob 20 positions cam disc 15b, and disc 11a is adjustable within the set but is not rotatable by a knob. Each pair of discs 11a, 11b ... 15a, 15b controls a respective switch 11-15. A combination of code signal bursts, with individual identifying frequencies, transmitted to the receiver are applied from the video amplifier over conductor 21f for segregation by filter rectifiers 21a-21e, and transposed at block 22f. Switches 11-15 effect the particular pattern of circuit connections from the rectifier units to the output conductors 1<11>-7<11>.

Title: Improvements in or relating to moving contact electric current converters
IPC: H02M1/26
Filed: 1937-11-22
Abstract: 506,015. Converting. SIEMENS SCHUCKERTWERKE AKT.-GES. Nov. 22, 1937, No. 32108. Convention date, Nov. 20, 1936. Addition to 492,369. [Class 38 (ii)] In a commutator switch converter as described in the parent Specification, wherein the contacts 19 constituting the interruption-gap are associated with a main choke 13 and parallel path 25, 26, an auxiliary choke 33 and a parallel path constituted by a discharge vessel 20, for example, is provided. The grid 21 of the latter is energized by an A.C. voltage in synchronism with the supply or is connected to an auxiliary contact 22 of are - resistant material which closes before the main moving contact of the gap 19 and applies a voltage to the grid to initiate the discharge. The resultant current in the vessel 20 and choke 33 is insufficient to saturate the latter, and it absorbs a large proportion of the total voltage-drop and reduces that across the gap to a value such that arcing cannot occur thereat. The vessel 20 may be protected from overloading by means of a resistance 24, or condenser and shunt resistance, or by a reversely-premagnetized choke which only unsaturates with overload currents and so reduces the current. The choke 33 may be short-circuited during switching-off, either by means of a synchronously-driven slip-ring, or by a commutator having resistances between its segments for gradually reducing the current, or by means of a short-circuiting winding with low leakage. The magnetization of choke 33 may be adjusted in readiness for closure of gap 19 by providing a winding 28 which reverses the magnetization during circuit-opening, the winding 28 being in circuit with a further choke 35 fed by an alternating voltage and arranged to be unsaturated during switching-on, or alternatively the choke 33 could be energized by a suitably-arranged D.C. source. The Specification as open to inspection under Sect. 91 contained references to Specifications 492,887, 493,436, and 497,768. These references do not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of coal tar
IPC: C10C1/04
Filed: 1927-12-02
Abstract: 301,645. Cooke, F. Dec. 2, 1927. Condensing plant and processes.-Tar is condensed from coke-oven gas and withdrawn from an air-cooled main 5. at a temperature of 160- 190‹ C., through a branch 6 leading to a seal pot 7. Part of this tar passes to a tank 9, which may be variably cooled, and is returned by a pump 10 to the end of the bench main 2 and through valve-controlled inlets 13 spaced along that main to regulate the temperature of condensation. Tar is also withdrawn from the seal pot into a tank 15 in which ammonium salts and light oils are extracted by means of steam admitted through a perforated pipe 16. The tar escapes into a gravity separator 19, the heavier tar passing under a partition 20 and thence to a drier 22 in which it is treated by hot air or gas. Liquor is discharged from the separator into the tank 9 and refined tar from the drier into a tank 26. The gas and tar fog passing the branch 6 are treated in dynamic and centrifugal separators 30, 31, ammonia liquor and lighter tars being returned to the tank 9. Ammonia is extracted by hot sulphuric acid in a vat 35 and water and oils are removed in condensers 36 and separated in a tank 37 to which the condensates from the drier 22 are also led. Steam from the tank 15 is passed through the condensers with the gas which is then led through benzole scrubbers 40. Benzolized creosote oil with naphtha and creosote oil from the tank 37 is heated and treated with steam in a still 45, crude benzole passing to a tank 48 and creosote oil being returned to the scrubbers. Some of the creosote oil may be led through a pipe 53 to the drum 22 to reduce the viscosity of the tar.
