Title: Improvements in electric resistance welding sets
IPC: B23K11/11
Filed: 1948-11-30
Abstract: 648,133. Electric welding. SOC. ANON. A. CITROEN. Nov. 30, 1948, No. 31020. Convention date, Dec. 10, 1947. [Class 83 (iv)] Means for forming a lap weld between two plates comprises a welding circuit arranged so that the surface leakage currents in the plates offset each other, and clamping-heads 4 ... 7 connected to the electrodes 8, 9 in such a manner that the welding pressure is independent of the pressure exerted on the heads. Each electrode is connected to its clamping-head by an adjustable spring 10 and, when the heads clamp the plates together, the welding pressure between the electrodes is entirely supplied by the springs. The welding circuit comprises two identical transformers 2, 3 connected to the electrodes and clamping-heads so that, on one side, the electrode is positive and the heads negative and, on the other side, the electrode is negative and the heads positive, the surface leakage currents thus being in opposite directions.

Abstract: 490,724. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. Nov. 12, 1937, No. 31088. Convention date, Nov. 17, 1936. [Class 97 (iii)] In a gyro-vertical for aircraft, in which the gyroscope is erected by air jets supplied from the rotor and under the control of gravitationally responsive shutters, means are provided for shutting off the air supply to all of the jets simultaneously without retarding rotation of the rotor or restricting the air flow therefrom. As shown, the spindle 11 carrying the rotor 6 and the armature 10 of the driving motor is journalled in the casing 5 which carries the field winding 12 and is universally mounted in the support 2. A blower 13 also fixed on the spindle 11 draws air over the armature 10 and downwardly through holes 14 in the web 15 of the rotor into a cylindrical chamber 17 at the bottom of the casing 5. From the chamber 17 the air escapes either through downwardly directed apertures 35 or through pairs of laterally directed opposed orifices 18, 181, 19, 19<1> which are differentially obscured by pairs of pendulous shutters 20, 20<1> and 21, 21<1>. Each pair of shutters, e.g. 20, 20<1>, is fixed to a shaft, e.g. 23, journalled by jewel bearings in lugs 25 depending from the casing 5. A cruciform shutter 28 is mounted on a vertical spindle in the chamber 17 and may be moved by an electromagnet 32, 34 against the action of a spring 30 from a position in which it closes the apertures 35 and leaves the orifices 18, 18<1>, 19, 19<1> open to a position in which it closes the latter orifices and opens the apertures 35 to permit the air to escape freely. The electromagnet 34 is energized during turning of the aircraft either manually or automatically. The gyroscope may be locked by the engagement with a projection 40 at the base of the chamber 17 of a four-finger cage of the type described in Specification 449,238, [Group XXI]. The knob for operating the cage may simultaneously close a switch for energizing the electromagnet 34.

Title: Improvements in devices for tightening the screw stoppers of bottles
IPC: B67B3/20
Filed: 1937-11-12
Abstract: 503,973. Stoppering etc.; chucks. HAYWARD, TYLER, & CO., Ltd., and HOWARD, G. P. E. Nov. 12, 1937, Nos. 31116/37 and 9208/38. [Class 125 (ii)] [Also in Group XXII] A device for stoppering and unstoppering bottles, consists of a flanged plug 11, Fig. 2,. screwed and pinned to a driving-shaft 1 and screwed into a sleeve 12. An inner flange on the sleeve 12 serves to retain a friction pad 13, while the outer flange forms, with the flange on the plug 11, a bearing for an inertia member consisting of three superposed annuli 16.. 18, held together by bolts. The inner edge of the lowermost annulus 18 is coned to guide the stopper. The inner edge of the centre annulus 17 is formed as a cam to engage grippers 15, pivoted to the sleeve 12. When the stopper of a bottle is pushed up into contact with the pad 13 the whole inertia member 16 .. 18 is lifted and disengaged from its driving means. At the same time the rotation of the inner elements 11 .. 13 is checked so that the inertia member 16 .. 18 rotates upon the sleeve 12 and moves the grippers into contact with the sides of the stopper, which is then unscrewed. When the bottle is lowered after the removal of the stopper, the inertia member 16 .. 18 drops back into engagement with its driving means and opens the grippers to release the stopper. A light braking action may be applied to the annulus 17, when the inertia member is lifted, to supplement the action of the stopper top on the friction pad. The device may also be used for tightening stoppers Fig. 1 shows a device for tightening stoppers which may also be used for unstoppering. The inertia member consists of a vertical shaft 1 carrying a friction pad 3, coned guide 4 and fly wheel 5. The upper part of the shaft 1 passes through a sleeve 6 to which is secured a continuously rotated pinion 7. The flywheel 5 normally rests upon a friction surface on the upper face of the pinion 7 the action of gravity being supplemented by a spring 9. When a bottle stopper, guided by the member 4, is pressed up against the pad 3, the flywheel 5 is carried out of contact with the pinion 7 and the tightening action is completed solely by the momentum of the inertia member. The devices described may form parts of complete bottling-machines.

Title: Brick cladding
IPC: B28B23/00
Filed: 1960-09-22
Abstract: 925,694. Furnace bricks. H. K. PORTER CO. Inc. Sept. 22, 1960 [Sept. 25, 1959], No. 32636/60. Class 51 (2). A refractory brick for lining furnaces is covered on four surfaces by a metal sheet and has two opposite surfaces uncovered, a pair of opposite ends of said sheet lying adjacent one another on one of said four faces and being secured to one another. The metal sheet 56 is initially formed as a flat plate with four rows of perforations 90 and in manufacture a brick 55 is placed on the sheet which is then bent to cover four surfaces of the brick, the positions of the rows of perforations 90 corresponding to the edges of the brick along which the sheet is bent. The provision of perforations ensures ease of bending and also allows bending to occur at the perforations even if variations in brick size occur. Staples 95 are inserted in the metal sheet, Fig. 4, to join adjacent edges thereof, the legs of the staples passing into recesses 94 in the brick which recesses have sloping walls so that the legs of the staples are clinched over. The staples 95 together with the adjacent areas of the metal sheet covering the recesses 94 are depressed, Fig. 6, so that the staples lie flush with or slightly below the outer surface of the metal sheet. The intrusion of the staples 95 and the depressions 96 of the metal sheet into the recesses 94 locks the brick into its metal casing. In a modification, Fig. 7 (not shown), the shape of the adjacent edges of the metal sheet is irregular so that any escaping furnace gases have a longer path to follow, and in a further modification, Fig. 8 (not shown), portions of the adjacent edges are perpendicular to their direction as shown in Fig. 4, allowing them to be joined by the same size of staple for considerable variations in brick size.

Abstract: 153,487. Gouinlock, W. F. Dec. 30, 1919. Glass houses.-The area to be heated in a hot-house is reduced in comparison with the area of growing surface by disposing the house against a sloping bank and providing an inclined single or double-glazed roof 17, a heating-chamber 1, a humidifying-chamber 4 and a dry fresh air chamber 2, fresh air heated by a furnace 5 being introduced by conduits 9, branching off an inclined passage 8, to a plurality of growing-beds 11 mounted one above the other in tiers. Each tier is divided by a partition 13, and the rear portion can be used for mushroom culture &c. Conduits 16 connect with the conduits 9 and permit the surplus air to rise from tier to tier. Drv heated air from the chamber 2 is projected by the vent 20 of a passage 19 against the inner face of the roof 17, thus insulating the adjacent plants from the cold outside air and decreasing frosting-up of the glass in winter. The air thus directed up the glass is kept heated by lateral steam or other pipes 18. Fig. 4 shows a modified form in which air heated by a corrugated partition 24 mounted over oil burners 22 may pass either directly up a flue 6 or may circulate by way of a damper 26 and a passago 27, between the outer and inner glazed roof surfaces 17, 28.

Title: Improvements in and relating to oil purification processes
IPC: C10G21/06
Filed: 1929-10-29
Abstract: Mineral oils used at high temperatures for a long time, e.g oils for lubricating purposes or for insulating electric transformers, capacitors, switches, or cables are freed from sludge or are prevented from sludging by a liquid solvent for the impurities which solvent is insoluble in the oil or is rendered insoluble.  Esters of inorganic or organic acids, and polyhydric alcohols are specified as suitable solvents.  For insulating purposes a mixture of 100 litres of mineral oil with 5-15 litres of tricresyl phosphate is preferred, the phosphate becoming progressively insoluble as the oil becomes oxidized or sludged, and carrying out the sludge.  For purifying a crude or sludged oil, 70-90 litres of the oil are agitated with 30-10 litres of a 1-1 mixture of tricresyl phosphate or dibutyl tartrate or dibutyl phthalate with acetic acid or other substance rendering the ester insoluble in the oil; the mixture is allowed to stand, and the oil layer is separated, washed with dilute sodium hydrate and water, and fractionally distilled, preferably in vacuo.  The recovered tricresyl phosphate is reused.  Or, for transformers, 5-15 per cent by volume of glycerine or glycol is placed beneath the oil in the container.  For purifying crude or sludged oil, 70-90 litres of the oil is extracted once or more with 30-10 litres of glycerine or glycol.
