Title: Improvements in or relating to the electric melting of glass or the like
IPC: C03B5/027
Filed: 1932-01-01
Abstract: 394,709. Electric furnaces for making glass &c. HARTFORD-EMPIRE CO., 333, Homestead Avenue, Hartford, Connecticut, U.S.A.-(Assignees of McIntosh, H. W.; 10, Remington Road, Windsor, Connecticut, U.S.A.) Jan. 1, 1932, No. 89. Convention date, Feb. 5, 1931. [Class 39 (iii).] In the production of glass, soluble silicates of soda and vitreous enamels, to prevent oxidation of the electrodes with consequent discolouring of the product, the electrodes 20, 21 are coated with the substance to be made before insertion in the furnace. The electrodes are of graphite and comprise a head portion and a stem to which terminals are attached. The electrodes and supporting blocks 31 are placed in moulds and the heads and stems are then coated with glass. The moulds may be filled in a vacuum or the air in the moulds may be displaced by a heavy non-oxidizing gas before the glass is poured therein. When the electrodes are withdrawn gas or oil burners are introduced through the electrode openings to heat the furnace. Batch is melted in the forehearth 15 or molten glass is poured therein, and after removal of the burners and insertion of electrodes 21 the gate 36 is raised and the glass flows into the bottom of the furnace. Current is then supplied to electrodes 21. Further charges are melted in the forehearth and run into the furnace, the electrodes 20 being eventually restored to the furnace and submerged by molten glass. Batch may then be fed through the opening 10 direct to the furnace. If the electrodes are coated with glass having a sufficiently high melting-point they may be inserted in the furnace before the latter is preheated. The forehearth may be replaced by a drawing kiln for making sheet glass.

Title: Improvements in or relating to the removal of metallising from metallised dielectricmaterial
Inventor: FORSHAW KENNETH GEORGE WILLIAM
IPC: H01G13/06
Filed: 1957-01-02
Abstract: 817,017. Removing metal by etectro erosion. TELEPHONE MANUFACTURING CO. Ltd. Dec. 23, 1957 [Jan. 2, 1957; Feb. 13, 1957], Nos. 168/57 and 4916/57. Class 83 (4). Metallizing is removed from selected areas of a metallized dielectric material by subjecting these areas to radio frequency energy of sufficient strength to vaporize the metal in these areas. The invention is applicable to the manufacture of capacitors from a strip comprising a metallic film of aluminium, cadmium, zinc or nickel deposited on a backing of paper or synthetic resin. For removing a longitudinal area or areas from the strip, the latter is wound in a reel and mounted on one or other of reel carriers 8 and is passed over guide rollers 9 and between a backing roller 10 and a spring-loaded demetallizing roller 7. The backing roller 10 may be of insulating material such as a ceramic or of metal covered with a layer of polytetrafluorethylene, or it may be wholly conductive or capacitative, or it may be conductive only adjacent the portion of metal to be removed, or be arranged to engage this portion only. The demetallizing roller 7 may be of a width corresponding to that of the portion to be removed and is then adjustable transversely of the strip by a knob 11, Fig. 2 (not shown). The upper pair of guide rollers 9 engage the metallizing and are connected to earth. A current at radio frequency is supplied from a generator 1 to the demetallizing roller 7. The frequency is adjustable by a control 3. The backing roller, if conductive, may be connected to the opposite phase of the radio frequency supply or it may be connected to earth. In an alternative embodiment, two coaxial demetallizing rollers 7 are used and connected to opposite phases of the supply or a sectional roller with two or more conductive areas may be provided. The demetallizing roller or rollers may be driven in a direction opposite to the movement of the strip to assist in removal of the metallizing. One or other reel 8 is driven selectively by selector gearing 21, Fig. 2 (not shown), from an adjustable-speed reversible motor 5. Tension adjusters 14 are provided for the strip. An extractor duct communicating with a blower 6 and filter 20 is provided adjacent the roller 7 for removal of the metal. The demetallizing machine may be housed in a transparent or windowed casing. In the manufacture of the capacitor two or more strips may be wound to a predetermined length and thereafter a transverse strip of metallizing is removed by a demetallizing roller of the same width as the strip. The demetallizing operation may be controlled manually or automatically by a turns counter. Specifications 483,029, 485,965, 551,757 and 593,468, [all in Group II], are referred to.

Title: Improvements in or relating to the manufacture of 25 to 30% liquor ammonia
IPC: C01C1/10
Filed: 1941-01-07
Abstract: 552,843. Distilling ammoniacal gas liquors. PARRISH, P., and KITCHEN, W. T. Jan. 7, 1941, No. 239. [Class 32] Ammonia liquor containing 25-30 per cent. ammonia is obtained from gas liquor by heating the gas liquor to about 105‹C. under a pressure which prevents vaporization of the water and flashing it in a still so that the ammonium compounds are completely dissociated and the ammonia, hydrogen sulphide and carbon dioxide flashed off cooling the gaseous products to absorb the ammonia in the water, passing the residual liquor to a liming still and recovering ammonia therefrom. The crude liquor is fed from pipe 1 through a washer A1 where it scrubs the gases formed in the process which are further scrubbed in washers A2, A3 with water. The total liquid from the scrubbers is passed to mixing tank B and thence by pump C through condenser D1 to preheater E. The liquor preheated to 105‹C. is discharged on to a plate 10 in a dissociation still F from which residual liquor passes to the usual liming vessels J1, J2 and thence to the ammonia still H from which ammonia is recovered overhead and after passage through the condensers D1, D2 is fed to absorber K cooled by coolers L1, L2, L3. The gases formed in the flasher F comprising ammonia, carbon dioxide and hydrogen sulphide are passed under pressure through a condenser G maintained at such temperature that the ammonia is condensed while the remaining gases pass to the washers A. The condensed ammonia is returned through line 14 to the mixer B. The heat exchangers E, G are maintained automatically at the required temperatures by regulators 7a, 7b, 12b, 20b of the leak port type described in Specification 116,074, [Class 135].

Title: Improvements in or relating to the manufacture of gelatine caps for bottles
IPC: B29D99/00
Filed: 1935-01-04
Abstract: In the preparation of gelatine caps for bottles, the cap in the dry or moistened state is treated with an aqueous solution of a volatile substance of such a nature that it is not of itself absorbed by gelatine, for example an aqueous solution of methyl, ethyl, or higher alcohol, or of a ketone such as acetone.  The caps are normally kept in well sealed containers and are applied to the bottles without preliminary treatment, immediately shrinking closely upon the bottle neck.  The caps exhibit great ductility, elasticity and resistance to tearing.  In an example caps made from gelatine and dried on suitable formers are soaked in a bath of 70 per cent aqueous ethyl alcohol for one to two days, then freed from superfluous liquid, and put loosely into well sealed containers.

Abstract: 713,786. Fluid-pressure servomotor-control systems. BENDIX AVIATION CORPORATION. Jan. 8, 1952 [May 11, 1951], No. 594/52. Class 135 A power-assisted steering mechanism for vehicles comprises a servomotor with two relatively movable valve-controlling members and means responsive to fluid pressure in the valve inlet to press said members to their neutral relative position, and means for automatically limiting the force exerted by the said means to a predetermined value regardless of the magnitude of the pressures built up in said inlet during operation of the mechanism. The servomotor comprises a power cylinder 10, Fig. I, coaxial with steering column 54 and containing annular pistons 22, 26 interconnected by a nut member 24 engaged by a shaft 32 connected to column 54 through a sliding joint 55. Axial movement of shaft 32 operates the closure member 66 of piston valve 60 controlling the fluid supply to and exhaust from the chambers 14, 16. The nut member is formed with a rack 40 engaging a quadrant 42 on a cross shaft 44 which connects with the steerable road wheels. Shaft 32 carries washers 90, 92 spaced apart by sleeve 94 and contacting levers 86, 88 respectively, which cause for any movement of the shaft an increased movement of member 66. The closure member has lands controlling recesses 62, 64 and having negative lap with respect thereto, recesses 70, 74 communicating with an exhaust outlet 78, and a recess 72 communicating with a pressure fluid inlet 76, Fig. 3. Recesses 62, 64 connect via bores in the cylinder wall with chambers 16, 14 respectively. Member 66 is urged to its central position in housing 63 by spring-pressed plungers 108 in chambers 111, Fig. 4, the chambers being interconnected by a bore 112 and in communication with inlet recess 72 via bores 116, 114, 118. During operation, the inlet pressure builds up as the resistance to steering increases and acts on the plungers to provide feel at the steering wheel. Excessive centering forces on the plungers are prevented by a relief valve member 124, Fig. 5, in bore 114, which is moved by inlet pressure in bore 132 against a spring 126 to connect bore 118 to bore 134 containing a check valve 136 and communicating with outlet 78, thereby limiting the pressure to a predetermined value. In the event of power failure, steering is effected manually with slight lost-motion to permit washers 90, 92 to abut the housing 63.
