Title: Improved apparatus for cleaning gas pipes
Inventor: GREENE THOMAS JOSEPH
IPC: B08B9/02
Filed: 1956-03-22
Abstract: 790,965. Cleaning gas pipes. EAST MIDLANDS GAS BOARD. Nov. 20, 1956 [March 22, 1956], No. 8929/56. Class 99(2). Apparatus for cleaning gas pipes comprises a manually operated piston pump 1 connected through an interposed filter 9 to a collecting chamber 10 which connects with a common inlet and outlet 38 to a gas pipe 39, and an alternative connection 6A from the pump to atmosphere through a manually controlled valve 25. The pump cylinder diameter and stroke are made comparatively large, e.g., 3 inches and 12 inches respectively, so that a suction stroke can induce a high velocity suction flow in the relatively small bore of the gas pipe so as to pick up loose deposit and detach larger lumps. The valve body 24 is gripped by the operator who works the pump handle 4 with his other-hand. The loose deposit is sucked in to the collecting chamber 10, the gauze filter 9 preventing it from reaching the cylinder. The valve 25 is opened after each suction stroke by a lever 30 disposed along the valve body and operable by the hand gripping the body so as to enable the return stroke to discharge to atmosphere through a flame trap by way of branch 34 and hose 37 instead of back into the pipe 39. The collecting chamber 10 is transparent to permit inspection of contents and is secured by a stirrup 14 having arms 15 pivoted at 16, with pressure applied to the the base of the chamber by a plate 17 welded to the end of a screw 18. In a modification, the apparatus may be mounted on a tripod having adjustable legs. According to the Provisional Specification the valve may consist of a ball or a metal cone.

Title: Improved method of thermally conditioning glass which is to be drawn into sheets
Inventor: LONG BERNARD
IPC: C03B5/183
Filed: 1956-03-23
Abstract: 786,253. Drawing glass. COMPAGNIES, REUNIES DES GLACES ET VERRES SPECIAUX DU NORD DE LA FRANCE. March 23, 1956 [March 28, 1955], No. 9103/56. Class 56. Glass passing from the firing zone 1 of a furnace to a shallow draw bath 3, Fig. 1, or a deep draw bath 19, Fig. 3, traverses a shallow covered canal 2 wherein it is thermally conditioned. The thermal conditioning consists in severely reducing the heat losses from the upper and side surfaces of the glass in the canal (as by selecting suitable materials for making and lagging the roof and sides of the canal), and simultaneously increasing the heat losses from the bottom of the glass. The heat losses from the bottom are increased preferably by substantially reducing the thickness of the bottom of the canal and by providing air coolers, cooling jackets or the like. Alternatively the bottom may be made of normal thickness but of material which has a comparatively high thermal conductivity, e.g., fused mullite or mullite and zirconium or corundum; the loss may be augmented by blowing air against the bottom. In Fig. 1, the bottom of the canal is formed of thin blocks, 6a carried by beams 31a, 31, 31b, with adjustably mounted watercirculating coolers 10. In Fig. 3 the watercooled bottom of the canal is supported by an arch forming the roof of a return canal 20 for the glass.

Title: Improvements in or relating to frequency modulated oscillating circuits and condenser microphones
IPC: H04R19/04
Filed: 1951-04-20
Abstract: 704,473. Condenser microphones ; circuits for electrostatic instruments. ETABLISSEMENT VELGA. April 20, 1951 [April 22, 1950], No. 9316/51. Class 40 (4) [Also in Group XL (c)] A condenser microphone comprises a diaphragm 1 and two hollow, semi-circular electrodes 2, 21 symmetrically arranged on the same side of the diaphragm forming capacitances with the latter. The electrodes 2, 21 are mounted on a ceramic disc 3 glued or otherwise secured to a holding ring 47, and on the opposite side of the disc opposite the electrodes 2, 2<SP>1</SP> are conducting coatings 4, 41 forming capacitances with the electrodes 2, 2<SP>1</SP> and an intermediate coating 5 presenting, if held at zero potential, cross capacity coupling between electrodes 4, 2<SP>1</SP> and 4<SP>1</SP>, 2. A shim 52 adjusts the spacing between diaphragm 1 and electrodes 2, 21 to between .007 and .02 mm. The electrodes 2, 2<SP>1</SP> may have air escape channels 60 opposite the diaphragm, or perforations. The condenser may be employed to frequency-modulate push-pull oscillator 6, 7, Fig. 3, with grids 12, 13 directly coupled to grids of a push-pull amplifier whose oscillations or those of the oscillator are then demodulated and amplified so that the circuit may act to connect up a condenser microphone to a public address system or hearing aid, with only oscillator grid potential between the diaphragm 1 and electrodes 2, 2<SP>1</SP> so that close spacing may be employed. In modifications, a single valve oscillator is employed and in Fig. 4 (not shown) additional pairs of electrodes are introduced between the electrodes 2, 2<SP>1</SP> and coatings 4, 4<SP>1</SP> whereby the electrodes 2, 2<SP>1</SP> may be operated at diaphragm, i.e. zero potential. Alternatively, electrodes 2, 2<SP>1</SP> alone may be used and connected to the oscillator through D.C. potential blocking condensers. By forming the ceramic disc 3 (Fig. 7) with a raised edge 57 or a recessed edge temperature expansion of the disc can be arranged to compensate for mean frequency variation of the oscillator, and the change in spacing of the electrodes 2, 2<SP>1</SP> from the diaphragm, when the former are at H.T. potential, for frequency variation due to H.T. changes. The central part of the cover screen for the microphone may be covered to provide more linear modulation.

Abstract: 913,821. Voltage, current, power measurement. PITTSBURGH PLATE GLASS CO. March 18, 1959 [March 26, 1958], No. 9322/59. Class 37. Apparatus for measuring a high value of rectified D.C. derived from an A.C. source comprises a transducer system responsive to the current and voltage applied to the rectifier to energize a thermoelectric converter generating a signal representing the supplied power, a measuring device responsive to the D.C. output voltage to produce a signal representative thereof; and a computing device responsive to both signals which divides the power signal by the output voltage signal and multiplies the product by a constant representing the system efficiency to produce a signal operating a D.C. indicating device for the required high value of D.C. Three-phase A.C. power energizes rectifier 3 over power transformer 1, 2 and the voltages from transformer 11, 12 energized by the voltages between lines 13a, 13b and 13b, 13c together with the outputs of current transformers 14, 15 in leads 13a, 13c are coupled to a thermoelectric converter 10 wherein they are transformed to heat energy which produces a direct voltage representing the A.C. power input. The direct output voltage from the rectifier operates a measuring device 6 which applies an electrical or mechanical signal to a D.C. computing device which divides it into the power signal from the converter. The resultant is multiplied by a constant representing rectification efficiency; the resultant voltage being measured to represent the direct rectified current. In Fig. 2 the direct output voltage may operate a null balance voltage recorder 206 linked over 205 to the slider 213 of a potentiometer across the power voltage of the converter 210 so as to divide the latter by the former to derive a voltage energizing potentiometer 214 preset to a ratio representing the rectification efficiency; the output voltage of which operates a direct voltage recorder 207 indicating the direct output current of the rectifier, which may be of any type or be replaced by a motor generator. The A.C. supply system may also be 1, 2 or 6 phase. The power voltage from the converter 10, and the voltage signal from recorder 6 may be transformed to corresponding pneumatic pressures and divided and multiplied by known means to derive a measurable pneumatic signal representing the D.C. output of the rectifier.

Patent GB-493291-A (GB)
Title: Improvements in and relating to electric switches particularly for refrigerators
IPC: H01H37/60
Filed: 1937-04-03
Abstract: 493,291. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. April 3, 1937, No. 9553. Convention date, April 3, 1936. [Class 38 (v)] A switch for controlling the circuit of an electric refrigerator comprises a contact 12 on a flexible conductor 13 adapted to be moved into and out of engagement with a fixed contact 11 by means of an insulating link 15 on a U-shaped member 16 pivoted at 17 and connected by means of a pivoted link 18 and tension spring 19 to an operating lever 20 pivoted at 21. Movement of the lever 20 in a clockwise direction moves the spring 19 past the dead centre position of link 18 and circuit is made with a snap-action. Since the spring 19 never crosses the pivot point 21, lever 20 is always biassed in the clockwise direction and so the switch always moves into the closed position when the opening force is removed. The switch is arranged to be opened on overload in the motor circuit by the engagement with an abutment 26 on lever 20 of a projection 23 on the free end of a bimetallic strip 29 provided with a heating coil 30 in series with contact 11, 12. The switch is also operated in accordance with the temperature of the refrigerator by means of a bellows 39 acting on a lever 37 pivoted at 38. When the bellows contracts, a spring 41 turns lever 37 in a clockwise direction causing a projection 24 to engage a lug 27 on lever 20 to open the switch, which automatically recloses when the bellows expand. The spring 41 is adjustably connected at 43 to a plate 44 which can be moved to the right or left by rotating a cam 59, having an-external knob (not shown) acting on an intermediate member 80 abutting against a stop 60 on plate 44. This alters the operating temperatures of the switch and in the position shown in which the cam 59 has been rotated to the full extent clockwise, the plate 44 is in its extreme right position in which a projection 25 engages a lug 28 on lever 20 to open the switch. If the cam 59 is rotated to its full extent in an anticlockwise direction, a recess 65 engages member 80 and spring 41 is so greatly tensioned that defrosting occurs. The temperature range is further variable by rotating member 80 so that recess 78 or 79 engages stop 60 and so varying the distance between cam 59 and plate 44. The operating. differential can also be varied by means of U-shaped spring 88 acting on lever 37 and the tension of which is adjustable by means of a conical headed screw 91. Specification 493,117 is referred to.

The rotors with either spur or double helical teeth may be of either the externallymeshing or the internally-meshing type and a similar construction may be used for the rotors of pumps of the meshing screw type. The discs may be stampings from thin metal sheets and may be used with the rounded edge on one side and the lip on the other as they come from the stamping operation. Or, the discs may be ground flat and be ground off towards the periphery to give a slight clearance between the tooth parts of adjacent discs. The discs are pressed together by fluid from the delivery which is admitted to recesses in the end walls of the chambers.
