Title: Improvements in or relating to television and like receivers
IPC: H04N5/08
Filed: 1936-07-08
Abstract: 477,897. Television. BAIRD TELEVISION, Ltd., and GILBERT, A. H. July 8, 1936, No. 18901. [Class 40 (iii)] One of two induction coils 6, 9 in the anode circuit of a thermionic valve 1 is coupled to a scanning oscillator 10 of framing frequency and the other is coupled to an oscillator 7 of line frequency. Combined picture and synchronizing signals are applied to the valve which is so biassed as to separate the synchronizing signals from the picture signals. A resistance 8 and condensers 12, 13 prevent signals at the line frequency reaching the coil 9, and a resistance 11 ensures that impulses, which are developed at the resonant frequency of condenser 13 and the coil 9, do not affect the generator 10. The coils are tertiary windings on feed-back transformers in the oscillators. Alternatively the coils are coupled with coils, which are separately connected to the grids of the oscillating valves. There is an electrostatic shield between at least one of the coils and the corresponding oscillator.

Title: Method for reducing the over-talking and over-hearing in long-distance combined double line and phantom circuits
IPC: C05F5/00
Filed: 1920-07-06
Abstract: 147,013. Siemens & Halske Akt.-Ges. March 22, 1919, [Convention date]. Drawings to Specification. Induction, preventing and minimizing.-Comprises a method of balancing the mutual capacities of wires composing two telephone pairs with or without a phantom circuit in order to prevent overhearing without having to cross the wires at frequent intervals. Two adjacent phantom circuits may be similarly balanced. The capacities of a considerable section of four-wire line, such as that lying between successive loading-coils, are treated as concentrated at a point, and the mutual capacities of the component wires are measured and equalized by the insertion of condensers. A second measurement is then made, and as a fine adjustment further capacity is added. Variable condensers may be used during the test, and subsequently replaced by fixed condensers of the required capacity. The resistances of the conductors, the capacities of the loading coils, the station connexions and testing systems may also be compensated, and the line may first be roughly balanced by crossing at a small number of points.

Abstract: 992,246. Boring earth &c. JOY MANUFACTURING CO. May 26, 1961 [June 13, 1960], No. 19058/61. Heading E1F. A core barrel assembly is inserted into a drill string and latched to the boring end of the string to receive the core, the flow of drilling fluid through the assembly being stopped when the barrel is filled or blocked. The assembly comprises a tubular body 52,58 having apertures 85, 88 for the fluid, a spear 28 on a slidable shaft 44 carrying a valve member 94, a slidable shaft 71 carrying a valve member 96, and a barrel 20 having a core retainer 17 and attached to the shaft 71. The assembly is latched to the string 1 by balls 86 which are pressed into engagement with a groove 86<SP>1</SP> by a part 92 of the shaft 44. In the latched position of the assembly the barrel is housed within the drill head which comprises reamer and drill section 3, 4 carrying diamonds 10, 12. When during drilling the barrel is filled or blocked it presses the shaft 71 upwardly, the member 96 stopping the flow of the fluid and the resultant rise in pressure indicating that the assembly should be brought to the surface. An overshoot 30 is lowered to engage the spear and pulled upwardly, the initial pull causing the shaft 44 to release the balls from the groove and free the assembly. The assembly is normally lowered under gravity into the string attached to the overshoot, but the member 94 may be screwed towards its seat, and the body may have a seal engaging the string so that the pressure of the fluid acts to feed the assembly. In modifications the member 94 is dispensed with and the member 96 may take other forms. The overshoot may have a seal engaging the string to permit pressure feeding.

Title: A process for the manufacture of pigmented threads and staple fibres of renegerated cellulose from viscose
IPC: D01F2/14
Filed: 1961-05-26
Abstract: In the manufacture of pigmented regenerated cellulose filaments by spinning viscose mixed with a pigment dispersion into a coagulating bath containing sulphuric acid, the pigments are dispersed in a mixture of water, a primary aliphatic amine containing 12 to 18 carbon atoms, and one or more amino compounds having the general formula:- <FORM:0926707/IV(a)/1> in which R represents an alkyl radical containing 12 to 18 carbon atoms, R1 represents -CH2CH2COONa and R2 represents hydrogen or -CH2CH2COONa. The pigmented filaments may be multi- or mono-filaments and may subsequently be cut into staple fibres.  The primary aliphatic amine may be lauryl or oleyl amine.  R may represent an alkyl radical derived from coconut oil, and R2 may then represent hydrogen. Alternatively, R may be an alkyl group derived from tallow and R2 may then represent -CH2CH2COONa. A list of white inorganic pigments (of which titanium dioxide is preferred) which may be used is given and also a list of coloured pigments. If coloured threads free from dichroism are to be produced, the pigment dispersion should contain a small proportion of a white inorganic pigment in addition to the coloured pigment.  The presence of the amino compounds in the viscose prevents or minimizes the precipitation of the pigments in the viscose when the latter is allowed to stand undisturbed.
