Title: Improvements in or relating to electric impulse generators
IPC: H03K3/78
Filed: 1944-09-27
Abstract: 590,480. Pulse generating circuits. STANDARD TELEPHONES & CABLES, Ltd. Sept. 27, 1944, No. 18522. Convention date, Aug. 12, 1941. [Class 40 (v)] In a pulse transmitter a blocking oscillator feeds pulses to a normally quiescent oscillator to cause it to generate a high-frequency pulse. Valve 2, connected as a blocking oscillator with feed back from the anode inductance 6 to the grid inductance 8, is biassed between pulses by the potential developed on condenser 9 which discharges over resistance 10 to allow the valve to conduct, a resistance 12 preventing the grid being driven excessively negative. The biassing condenser 9 and resistance 10 may be in the grid circuit. When the anode current of valve 2 cuts off, the sudden rise in the anode potential is applied to a high-frequency oscillator consisting of valves 38, 39 with lecher grid and anode circuits. To terminate the high-frequency oscillations, the negative pulse from the grid of valve 2 is fed over a delay circuit comprising a coil 51 and condenser 52 and applied as a negative bias to the grid circuit of valves 38, 39.

Abstract: 1,162,604. Non-woven pile fabrics. SOC. SOMMER S.A. 25 April, 1967 [27 April, 1966], No. 18969/67. Headings D1K and D1R. A non-woven pile fabric is composed of at least one web of tangled substantially continuous synthetic filaments and is characterised in that the filaments are oriented through the web and form loops protruding from one face of the web. The process for making the non- woven fabric is characterised in that there is formed a web of tangled synthetic substantially continuous incompletely stretched filaments, and that some of the filaments are driven through the web and at the same time stretched, to cause them to protrude in the form of loops from one of the faces of the web. The filaments are preferably oriented through the web by a needling process, the needles having a smooth shaft and at least two terminal points separated by a recess. The filaments may be broken during their orientation through the web. The web may be heated to the optimum stretching temperature for the filaments prior to the loop formation. In a further embodiment, the web is subjected to a humid heat 'treatment after the loop formation. During the passage of the web through the needle loom each loop may be successively subjected to the action of needles of increasing height. In a further embodiment the web is passed between a rotating cylinder having needles on its periphery, and a grooved bearing surface. The web may be needled prior to the loop formation and in a further embodiment, the web is attached to another web of completely stretched filaments. The face of the web through which the needles enter may be coated with a mechanically foamed plastics or rubber material which is allowed to gel.

Abstract: 798,494. Liquid fuel furnaces. BABCOCK & WILCOX, Ltd. June 20, 1956 [June 20, 1955], No. 19083/56. Class 51 (1). A cyclone furnace primarily adapted for burning solid fuel is operated solely upon liquid fuel which is introduced with 40-60 per cent of the total air required for combustion through the inlet port provided at one end for pulverized fuel and air, and the remainder of the air is introduced tangentially as secondary air. A cyclone furnace has walls formed of studded tubes covered by a refractory lining, a reentrant gas outlet throat 24 coaxial with the horizontal combustion chamber, and a slag outlet 28 for use when the furnace is operated with solid fuel. Tangential, damper-controlled secondary air inlets 18 are supplied with air under pressure from a duct 16. A liquid fuel atomizer 42 is mounted concentrically with a fuel supply opening 40 to produce a conical spray of liquid fuel. Air under pressure from a duct 52 passes through a cylindrical air register 56 coaxial with the fuel atomizer 42 and having pivoted air doors imparting a whirl to the air, to a port ring 60 in the form of a truncated cone with its narrower end at the fuel inlet port 40. The air supply is arranged so that 40-60 per cent of the combustion air is supplied as primary air mixed with the liquid fuel, thus reducing the pressure drop through the furnace, which is a minimum when 50 per cent of the air is introduced as primary air. The furnace can easily be converted to burning solid fuel by removing the fuel atomizer and primary air supply apparatus and installing the solid fuel supply duct. Specification 598,191, [Group XXXVI], is referred to.
