Title: Improvements in kilns
IPC: F27B17/00
Filed: 1926-06-18
Abstract: 269,361. Minter, M. M. June 18, 1926. Continuous kilns. - In a kiln system comprising separate kilns 15 - - 21 connected for continuous working the ducts 23 between adjacent kilns are fitted each with a pair of spaced dampers 33, 40. between which dampered connections 35, 38 open into the duct, the former leading to a header flue 34 and the latter to a, waste heat flue 37. Between each damper 33 and the adjacent kiln is a further dampered connection 28 to an exhaust flue 20 in communication with a fan 30. In normal operation waste heat from a kiln under fire is passed through one or more adjacent kilns on its way to the stack, and any surplus combustion products may be passed to the waste heat flue 37 for use elsewhere, e.g. in a drier. When a kiln is cooling down air may be drawn therethrough to the header 34 and supplied to any other kiln of the series. Each kiln has a central outlet opening 22 communicating with a flue 23, the opposite end of which is connected to an annular inlet flue 45 in the next kiln. This flue extends beneath the fire-place and is connected thereto by channels 47 having flared delivery ports 48. The air or gas supply through the channels 47 of the various fire-places is equalized by blocks 49, which are varied in size according to their distance from the inlet to the flue 45. The fire-place openings may be divided horizontally by partitions 44, and fires may be built both on and beneath the partitions.

Title: Improvements relating to sewing machines for stitching objects on to tapes, bands, articles of clothing and the like
IPC: D05B29/06
Filed: 1939-05-24
Abstract: 526,790. Sewing - machines. NEWEY BROS., Ltd., and SIMPSON, W. May 24, 1939, No. 15375. [Class 112] In a machine for attaching eyeletted tape! and having a needle-bar with a feeding movement, the needle is caused to descend so as to miss the eyelets. A finger 15 carried by a lever 14 rides over the wires 17 of the eyelets and thereby raises a detent 23 on a lever 21 into line, as shown, with a projection 13 on the needle-bar frame. The needle-bar frame is thereby prevented from making its return feed movement to the full extent to the left if the descent of the needle should take place whilst the finger 15 is raised by an eyelet. Lost motion is provided for between the needle-bar frame and its operating lever to permit this action. A guard plate 26 lies against the side of the finger to protect it and also keeps the work level near the finger. The feeding surface of the feed-dog is reduced so that the finger may operate above a part of the throat plate surface. Specification 313,841, [Class 112], is referred to.

Title: Improvements in and relating to the recording of sounds by means of a film
IPC: G11B7/00
Filed: 1923-06-18
Abstract: 199,406. Aigner, F. June 19, 1922, [Convention date]. Thermionic amplifiers, oscillation generators, and modulating systems and apparatus.-Sounds or other oscillations are recorded on a sensitive film by superposing them upon high-frequency oscillations in a circuit containing a coil which produces an electromagnetic field arranged to affect the plane of polarization of a polarized light ray passing to the film. The circuit of a microphone M<1>, Fig. 1, is connected across a transformer T with the grid circuit of a thermionic tube amplifier R<2>, and the magnified oscillations in the plate circuit of this amplifier are superposed on high-frequency oscillations generated in the plate circuit of a thermionic tube generator R<1>, which circuit contains a condenser c with a shunted high-frequency inductance D', and a grid coil L. The grid is directly connected to this plate circuit. Branching off from this highfrequency circuit, and adapted to be tuned therewith, is an oscillatory circuit containing a coil M, condenser C and, if necessary, damping resistance W. The light ray from a source J passes through a condenser lens S and a polarizing nicol m and then through a cylindrical glass rod f capable of turning the angle of the plane of polarization under the action of the varying oscillations in the coil M through which the rod extends. The ray passes from the rod through an analyzing nicol n and a lens q to the film F to produce a record of the sound &c.

Title: Improvements in electric arc heating torches
IPC: B23K28/02
Filed: 1941-12-08
Abstract: 553,914. Electric gas torches. DORRAT, J. A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 8, 1941, No. 15820. [Class 39 (iii)] In an atomic hydrogen torch, conduits 1, 2, each supplied with gas and carrying refractory metal electrodes 3, 4, are formed with a metal body la having a slightly eccentric bore 1b to receive the electrode 3. A nozzle body 1c also has a slightly eccentric bore for the electrode which is firmly gripped when the parts are screwed together, and a protecting tip 1g fits over the free end of the nozzle body. Apertures 1f are provided for the passage of gas. Gas and electric current are conducted to the electrodes through pipes 1j, or 2j, which are releasably connected by couplings 1k, 2k. The current-carrying gas tube 10 is enclosed in but insulated from a metal casing 11, and the tube 20 is inclosed in, and in contact with, a metal casing 21, and is longitudinally movable within it. The tube 10 terminates in a metal block 12 with a through bore, which is connected to another block 15 supplied with gas through a pipe 16. The block 12 is also connected to an electric supply lead 13. The tube 20 is connected to a metal block 22 provided with rack teeth 23, and the block 23 is connected by a sliding joint to the block 24, which receives gas through pipe, 25 and current through a supply lead 26. A handgrip 31, 32 of insulating material is made in two parts as shown, and supports an actuating pinion 37 operated by an external disc 38, so that the tube 20 and conduit 2 may be moved relatively to the conduit 1 to regulate the arc.

Title: Improvements in or relating to gas controlled audible signalling apparatus
IPC: B63B45/00
Filed: 1944-08-18
Abstract: 588,832. Audible signalling apparatus. GAS ACCUMULATOR CO. (UNITED KING- DOM), Ltd., and DORTON, E. W. Aug. 18, 1944, No. 15824. [Glass, 118 (ii)] [Also in Group XXIX] A gas-operated audible signalling apparatus of the type wherein gas at relatively constant pressure. is supplied .(through a control valve operated by a gas-operated timing device) to a cylinder in which a signal-actuating piston operates, is characterised by the provision, between the gas source and the control valve, of a pressure chamber which is fully charged before each operation, and of means for cutting off or restricting the flow of gas thereto during discharge therefrom, whereby a substantially predetermined quantity of gas is fed to the cylinder at each operation. As shown, the pressure chamber 27 serves also to house the control valve 26 which is spring-loaded on to the seat 29 to prevent the gas from a container 16 and pressure regulator 15 from reaching the cylinder 1 containing the striking piston 2 until the valve is raised by a timing device (see Group XXIX) through the rod 25, the valve then coacting with the seat 11, to shut off the supply. The pressure on the rod -25 is maintained until the piston 2 has completed its stroke, when exhaust gas through an outlet pipe 6 causes the piston 37 to lift the valve 38, thus allowing the pressure in the timing device to drop. The choke 13 is so adjusted that at each operation the chamber 27 fills before the timing device operates the rod 25 ; this choke may alone control the supply of gas to the chamber 27, the seat 11 for the valve 26 being omitted. Oil which leaks through the aperture 45 is carried up by the exhaust gas to lubricate the piston 37. In a modification (Fig. 2, not shown), the valve 38 is actuated by a system of levers connected to a movable member frictionally mounted in the wall of the cylinder 1 and having projections which are engaged by the piston 2 at the ends of its stroke.
