Title: Interlaced scanning for television
Inventor: SCHLESINGER KURT
IPC: H04N5/073
Filed: 1938-06-20
Abstract: 520,775. Television. RADIOAKT.-GES. D. S. LOEWE. June 20, 1938, No. 18236. Convention date, June 21, 1937. [Class 40 (iii)] The frame oscillat- or for an interlaced scanning is tripped by a potential consisting of the isolated frame synchronizing signal on which is superposed an oscillation whose frequency is double that of the line frequency and which is derived from the line oscillator which is controlled during the period of the frame synchronizing signal. The received frame synchronizing signal 20, Fig. 2a, degenerates into the pulse 21, Fig. 2b, when isolated, so that the point z at which the frame oscillator is tripped occurs on a slowly rising front ; by adding an oscillation 22, Fig. 2c, a wave-form 23, Fig. 2d, is obtained in which the tripping point z occurs on a steeply rising front with less danger of variation in control. The oscillations 22 are obtained from a tuned circuit coupled to the line oscillator and this oscillator must not vary during cessation of line synchronizing signals when a frame synchronizing signal occurs. This is achieved by transmitting the frame synchronizing signal with gaps 24, 24a, Fig. 4, spaced apart by a line period. Such signals may be produced by associating the scanned area with synchronizing signal generating strips 23, 22, Fig. 3, or by generating the signals by a light syren 25, Fig. 5, in which the apertures 26 are spaced apart by a distance greater than the illuminated area 27. Another method of generating such gapped signals consists in applying the ungapped signal from a lightsensitive cell 28 to a valve 30, Fig. 6, which is interrupted by pulses on the grid 33 from a generator 31, while the generator 31 simultaneously supplies a pulse of opposite phase to valve 34.

Title: Method of and apparatus for testing the productivity of a formation in a well
IPC: E21B49/08
Filed: 1926-07-23
Abstract: 279,175. Simmons, J. T. July 23, 1926. Wells. - To test the productivity of a formation encountered in drilling an oil &c. well without removing the mud - laden flushing liquid from the well, a single string of pipe or casing, closed to the contents of the well, is lowered into the well, and sealing means thereon is caused to shut off the formation from the upper strata; the pipe or casing is then opened to the formation to allow fluids from the latter to ascend therein. As shown, a pipe 23 has at the lower end a valve comprising a member 19 threaded to the pipe and provided with ports 17, 18, the member 19 being mounted on an upper extension 7 of a member 4 with ports 5, 6, and the members 4, 19 being relatively rotatable to bring the ports 17, 18 and 5, 6 into or out of communication; a pin 25 and slot 24 limit such relative rotation. The lower end of the member 4 is bevelled and below it is arranged a conical packer 15 of rubber, lead &c. A reduced bore 2 is formed at the foot of the well and extends into the formation to be tested. The pipe 23 is lowered into the well with the valve 4, 19 closed and the packing 15 is forced info the mouth of the reduced bore 2 to shut off the latter from the mudladen fluid in the well 3. The valve is then opened by rotating the pipe 23, when the well may come into production, or if the pressure is insufficient for production, fluid may flow from the formation into the pipe 23 which, after closing of the valve, is then raised to the surface for examination. A perforated pipe 12, closed at its lower end, may be arranged below the packer 15.

Title: Carrier wave signalling system
IPC: H04B3/54
Filed: 1943-11-06
Abstract: 577,572. Duplex signalling. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). Nov. 6, 1943, No. 18451. [Class 40 (iv)] [Also in Group XL] A combination transmitter-receiver circuit for carrier wave signalling comprises a tuned circuit transformer coupled to a transmitter and a receiver, a single local oscillator of stable frequency feeding the transmitter and also feeding a frequency-changing device to provide beat reception, and a narrow band filter for selectively passing the beats to the receiver. As shown in Fig. 1, a line L connecting the two stations is connected to earth at each station through a tuning circuit 1, 2 and a transformer 11 having windings connected respectively to the carrier transmitter 5 and the frequencychanger 6 of the receiver. The station has a stabilized carrier generator 3 connected through amplifiers 4, 5 to the transmitter, and through amplifier 4 to the frequency-changer 6 of the receiver. The received wave beats with the carrier from the source 3, and the beats are amplified at 7 and pass through a filter 8 and detector 9 to operate a relay 10. Signals are sent by energizing the relay 12 to complete the circuit of the amplifier 5; and when the relay 12 is de-energized, the receiving circuit is completed. In Fig. 2, the circuit is modified to permit simultaneous transmission and reception, the local carrier being fed to the frequencychanger 6 partly from the amplifier 4 through a phase-adjuster 15, and partly from the secondary coil 13 of a transformer in the lead to the line L, the components being adjusted to phase quadrature. The amount of local carrier fed from the coil 13 is reduced by a partial balancing of the primary coils, one of which is loaded by an adjustable resistance 14. In this way, the amplitude of the local carrier supplied to the frequency-changer 6 is kept substantially constant, whether the transmitter key is open or closed. Radio transmission may replace the line transmission shown. Specifications 6203/07, [Class 40], 5133/10, 170,154, 184,904, 185,475, 186,946 and 314,869, [all in Class 40 (v)], are referred to.

Title: Improvements in or relating to flexible sized or impregnated sheet material suitable as a base for artificial leather, adhesive sheets or tapes
IPC: C09J7/21
Filed: 1947-07-11
Abstract: A rubber composition adapted to be applied to a fibrous base and to be vulcanised thereon (see Group VIII) contains broken-down rubber, a resin, a self-vulcanising organic accelerator, and an activator for the accelerator.  The rubber which may be latex crepe, smoked sheet, reclaim, or synthetic rubber, is broken down by mechanical working in the presence of heat, air or oxygen, and, if desired, a small amount of the zinc chloride double salt of phenyl hydrazine, or naphthyl-beta-mercaptan.  The self-vulcanizing accelerator may be a thiuram polysulphide such as dipentamethylene-thiuram-tetrasulphide, and tetra methyl-thiuram-disulphide, and the activator may be zinc oxide, zinc abietate formed by reaction of zinc oxide and rosin, or calcium abietate.  The resin is water-insoluble and may be a solid or liquid resin.  Liquid resins specified are methyl abietate, which may be hydrogenated, and sticky polyisobutylene.  Suitable solid resins are rosin, ester gum, hydrogenated rosin, hydrogenated ester gum, dammar, copal, coumarone resin, hydrogenated indenecoumarone resin, and an oil-soluble phenolaldehyde resin that is hardened during heating of the impregnated backing.  Insoluble resinates may be formed by reaction of the rosin with zinc oxide, magnesia, or lime, either in the mix or before incorporation therein.  Five per cent of zinc oxide on the weight of the rubber is sufficient to activate the accelerator, but more may be added, e.g. up to 400 per cent, as a pigment.  A further accelerator, free sulphur, clay, carbon black, whiting, plasticisers, and antioxidants may also be added.  The impregnated sheet is put through a drying oven to remove solvent and vulcanise the rubber.
