Title: Improvements in and relating to wired broadcasting systems
Inventor: GABRIEL RALPH PARTON
IPC: H04N7/173
Filed: 1968-08-09
Abstract: 1,272,594. Wired broadcasting systems. COMMUNICATIONS PATENTS Ltd. 5 Aug., 1969 [9 Aug., 1968], No. 38108/68. Heading H4R. In a wired broadcasting system each subscriber is connected to a programme exchange by a respective feeder cable Fig. 2 having a twisted pair of insulated conductors 14, 15, to convey signals from the programme exchange to the subscriber, and a pair of control conductors 16, 17, to carry control signals from the subscriber to the exchange. The control conductors are arranged in the interstices formed between the pair of signal conductors and convey to the exchange programme selection signals, pay programme acceptance signals, and audience response signals if required. Fig. 4 shows an embodiment of a system in which a programme exchange, 24, is fed with vision signals of three programmes on coaxial lines 25, 26 and 27 and audio signals on pairs 28, 29 and 30. The vision and corresponding audio signals are combined on respective trunks 34, 35 and 36, which are connected to the programme selector switches, such as 37, of which one is provided for each subscriber. The selector switch is positioned by an electromagnetic driving device 38 under the control of signals received from the subscriber over the control pair 46 while the selected programme is transmitted to the subscriber over the signal pair 43 via a balun transformer 39 and a pay programme lock-out switch 41. Also transmitted over the signal pair 43 is a charge signal which operates an indicator 44 at the subscribers station to indicate the programme price and acceptance of the charge is indicated by the subscriber by connecting a tone generator 47 to the control line which signal unlocks the lockout switch 41 and registers the appropriate price on the pay meter 50. In order to assess programme popularity a constant voltage supply 52 is connected to each programme trunk line and each subscriber has a load 56 which draws a predetermined current from the trunk line to which it is connected, so that the programme popularity may be measured by the current meter 53, 54 or 55, through which the supply 52 is connected to the trunk lines. In addition the programmes selected by a particular subscriber may be recorded on meters 59 to 61 connected via a switch 57, coupled to the programme selector switch, to a power supply 58. A further tone generator 62 is provided at the subscribers station in order to provide audience response signalling over the control line.

Abstract: 391,908. Colour photography. KELLER-DORIAN COLORFILM CORPORATION, 522, 5th Avenue, New York, U.S.A. Dec. 29, 1931, No. 35876. Convention date, Jan. 27. [Class 98 (ii).] MoirÚ patterns are avoided in the reproduction by projection-printing of colour-record images on lenticular films by interposing between the original film and the sensitive lenticular film a device such as a direct-vision composite prism which disperses the light, for example to the extent of from ¢ to 1¢ times the width of a lenticle measured at the surface of the sensitive film. The direction of dispersion is perpendicular to that of the lenticles in the case of linear lenticular films, and in any direction in the plane of the film in the case of picot films. The printing light 1 may be white, such as that of a Nernst lamp or arc light giving a continuous spectrum ; or may be coloured, comprising one or more colour bands. In front of the light is a collimating lens 2 projecting substantially parallel light upon the original film 3. Projection on to the sensitive film 15 is effected by an objective 16 comprising two symmetrical lens systems 20, 21 of known kind and preferably of long focus, midway between which is arranged in their common focal plane a diaphragm 34 against which rests, in a position adjustable by a screw 38a, a direct-vision composite prism of the Amici type, comprising a flint glass element 36 and two crown glass elements 37, 38 of slightly smaller angle. The exposure is controlled by a shutter comprising discs 7, 9 having overlapping apertures 8, 10, which may be adjusted to give any desired opening, the discs being mounted on a shaft 11 driven by a gear 14 in synchronism with the film-feeding gear.

In a wall heater for heating rooms and comprising a burner 12 fed by a liquid fuel vaporizer 8, a fuel buffer tank 6, which may be the reservoir of a level regulator, supplies fuel to the vaporizer the liquid level in the tank being in direct communication with the primary combustion air in chamber 5 through an annular orifice around the vaporizer 8, thereby ensuring a regular supply of liquid fuel to the vaporizer. As shown the fuel, e.g. petroleum, which is supplied from a separate level regulator 14 flows into the buffer tank 6 in which is situated a riser tube 9, and is heated to become vaporized, the vapour passing through nozzle 10 into burner tube 12 through mixing tube 11, where it is mixed with the primary combustion air introduced into chamber 5 through intake opening 3. This air/vapour mixture burns at the apertures of the tube 12. Partition plate 4 has an adjustable opening 13 which both allows sufficient secondary combustion air into the main chamber and prevents burnt gases being recirculated to mixing tube 11, these burnt gases flowing out through opening 2.

Abstract: 1511650 Mechanical switches LUCAS ELECTRICAL Ltd 26 Aug 1975 [12 Sept 1974] 39742/74 Heading H1N An electrical switch assembly comprises first and second operating members 12, 13 rectilinearly movable relative to a housing 11 for operating respective switch contacts, a wall 14 of the housing 11 extending between the two members 12, 13 and having a transverse slot (15) (Fig. 6, not shown) along which is movable a blocking element 16 having each end co-operable with a respective one of the operating members 12, 13 such that the second operating member 13 is prevented from moving from a first to a second position before the first operating member 12 has been moved to its second position and the first member 12 is prevented from moving back to its first position before the second operating member 13. The first and second operating members 12, 13 operate the sidelamps and headlamps respectively of a vehicle so that the sidelamps must switched on before the headlamps and switched off after the headlamps. One end of the blocking element 16 is received in an inclined groove 17 in the operating member 12 and the other end of the element 16 is engageable with a vertical groove 18 in the member 13. When the operatmember 12 is in the off position the element 16 is displaced from the groove 18 and prevents movement of the operating member 13 to its on position. When the operating member 12 is moved to its on position in which it is retained by a detent against spring bias, the element 16 is moved along the slot (15) in the housing wall 14 to a position aligned with the vertical groove 18 allowing the operating member 13 to be moved to its on position. In the on position of the two operating members 12, 13 the groove 18 prevents movement of the element 16 along the slot 15 and groove 17 of the operating member 12 which cannot therefore be moved back to its off position while the operating member 13 remains in an on position.

Abstract: 1320632 Purifying sugar juices SYNDICAT NATIONAL DES FABRICANTS DE SUCRE DE FRANCE 25 Aug 1971 [25 Aug 1970] 39908/71 Heading C6B In a process for purifying raw sugar juice, e.g. from sugar beet, the juice is passed through a strong cation exchanger, and then neutralized with lime, e.g. milk of lime or powdered lime, and filtered, after which it is passed in succession through a second strong cation exchanger and a weak anion exchanger. As shown, the juice is passed firstly through a cooler 11 where its temperature is lowered to about 10‹ C. to prevent inversion before it enters the ion exchanger 10 containing a strong cation exchanger resin. On leaving the exchanger 10 it is limed at 12 and reheated at 13 to a temperature of 65‹ to 90‹ C. before passing through a filter 14 to a cooler 15 and thence in turn through the second strong cation exchanger 16, the weak anion exchanger 17, an evaporator 18, and a further purification stage in which phosphoric acid and lime are added at 19 in advance of a filter 20 and a mixed weak cation and strong anion exchanger 21. The Specification also describes a method of regeneration in which the anion exchanger 17 is regenerated with an ammonia solution which, on leaving the exchanger, is routed to elute the cation exchangers 16, 10, and the latter are regenerated with nitric acid of which that leaving the exchanger 16 is routed to elute the anion exchanger 17.
