Title: Improvements in and relating to heat insulation
IPC: F16L59/06
Filed: 1939-03-24
Abstract: 526,668. Cellular sheet materials. ALFOL INSULATION, Ltd., and SYKES, J. March 24, 1939, No. 9342. [Classes 96 and 140] [Also in Groups XIII and XXII] Heat-reflecting sheets, e.g., of metal foil, which are used to define air layers for heat insulation, are formed with creased folds c and with a crease at g midway between the folds c. Ribs d are thus formed, and their further spreading is prevented by strips e stapled at f to the sheet a. The creases enable the sheet to be folded into a flat pack, as in Fig. 2, for transport, or the ribs d may be folded against the sheet a, as in Fig. 12, so that the sheet may be rolled. In alternative forms the ribs may be formed in the strips e, the strips e may be interrupted between ribs, the strips e may be provided on both sides of the sheet, the strips e may be replaced by another sheet of heat-reflecting material, the strips e may be omitted and the walls of the ribs stapled together, and an additional sheet of material may be laid over the top and stapled to the ribs. The sheet a may be of aluminium foil, paper, cardboard, asbestos, textile cloth. synthetic resin paper or cellulose, or cellulose derivative containing particles of metal or metallic lustre. Metal foil coating, or metallizing, may be applied to the sheet, and the metallic surface may be protected by lacquer or anodic oxidation. The strips may be replaced by wire, string, card, or tape, and the stapling may be replaced by the use of adhesive, welding, interlocked indentations, or by knurled wheels. The crests of the ribs may be provided with projections.

Title: Improvements in or relating to tuning fork adjustments
IPC: H04L13/04
Filed: 1924-04-12
Abstract: 233,854. Muirhead & Co., Ltd., and Muirhead, F. H. April 12, 1921. Tuning.-In an arrangement for adjusting the frequency of a tuning fork, without stopping its vibration, by sliding weights along the tines, a sliding movement is imparted to a plate D provided with a transverse slot or slots engaging members projecting from the weights C. In one construction, Fig. 2, the projecting members are formed as rollers c mounted on ball bearings' c<1> around pins c<2> on the weights. The plate D is secured to a block adjustable along an extension a<1> of the stem of the fork, through a rack and pinion, by turning a knob E. After adjustment the plate D is moved back slightly to a position in which the rollers are clear of the walls of the slot or slots. In a modification, Figs. 4 and 5, provision is made for preventing any sliding of the weights on the tines A due to the vibration of the fork. For this purpose each weight is formed with a transverse passage c<3> to receive a plunger which is pressed against the side of the tine A by a strong spring f<1> held in place by a screwed plug f<2>. The plunger comprises two portions F connected by a stem f. The roller c engaging the slot in the plate D is mounted on an arm c' carried by a shaft c<6> passing through the weight C into the channel c<3> adjacent to the stem f. The inner end of the shaft c<6> carries a cam c' with a flat portion bearing against the wall of the plunger, as shown in Fig. 5. The initial movement of the plate D moves the arm c<5> against one or other of two stops c<8>, and the resulting rotation of the cam c' moves the plunger to release its grip on the tine. To prevent looseness of the weight on the tine when this grip is released, additional smaller plungers may be arranged to be pressed against the tine by springs which are not strong enough to prevent free adjustment of the weight.

Abstract: 839,247. Nuclear fission reactors; gas discharge apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 17, 1951 [April 18, 1950], No. 9443/50. Classes 39(1) and 39(4). Apparatus for producing thermo-nuclear reactions comprises a toroidal vessel for containing a gas at a low density and a primary conductor loop system in the vessel for inducing an orbital current flow in gas contained in the vessel to maintain the gas in an ionised energetic self-contained state. Fig. 1 shows a plan view of the apparatus wherein the toroidal vessel is made of two copper tubes 1, 2 joined together by quartz annuli 3, 4 and surrounded by a cooling jacket ; the vessel is provided with ports 5, 6 containing baffles to allow it to be evacuated and filled with gas at a desired pressure. Eight semi-circular conductors (of which four, 9a, 9b, 10a, 19b are shown), are arranged inside the toroid and are surrounded by conductive tubes through which an oil coolant may pass ; the conductors are joined together outside the toroid to form a primary winding of four, two or one turns surrounded by an iron circuit comprising metal tape 18 wound on a former. In operation the toroid is filled with gas, e. g. deuterium or tritium, to a pressure between 0À01 and 0À1 mm. of mercury, a steady flow of gas being maintained between the inlet and outlet ports to prevent the accumulation of impurities. A current of high frequency, e.g. 0À1 to 20 Mcs /sec., is established in the primary conductors and a ring discharge initiated in the gas by applying a high frequency voltage to an insulated electrode 17 projecting into the discharge space. When the discharge current has reached several hundred amperes, the discharge becomes constricted and the pressure may be reduced to 10-<SP>5</SP> mm. and the current increased by increasing the primary voltage.

[Also in Division F1] A rotary drive, e.g. for winding drums, sprockets or pin gears, comprises a toothed driving wheel 3 permanently in mesh with screws 1 and 2 having pistons at both ends, pressure medium being applied to one piston, e.g. the upper piston of screw 1, to move its screw linearly to rotate wheel 3, while, at the same time, the second screw is rotated by an hydraulic motor 15 acting through a rack 17 and pinion 19 splined at 21 to the screw, so that the second screw does not drive wheel 3 but moves in the same direction as the first screw. At the end of the stroke, the screw movements are reversed, so that continuous rotation of wheel 3 is obtained, the first screw being rotated whilst the lower piston of the second is subjected to pressure medium to perform a driving stroke. The drive may be automatically controlled, so that under low load drive is effected only by rotating the screws, and under high load the above operation takes place. The rotated idling screw is timed to complete its stroke before the pressure-actuated working screw. If the pressure supply is discontinued with the screws in an intermediate position, one of the screws is automatically moved to an end position.

Title: Improvement in tire building machine
IPC: B29D30/24
Filed: 1925-04-14
Abstract: 232,595. Backdahl, K. G. A. April 17, 1924, [Convention date]. Tyre covers, making.-A tyre casing is shaped from flat band form by rotating the band at high speed, the edges being caused to approach one another whilst the intermediate portion is forced outwardly and expanded into arched section by the centrifugal action. To increase the centrifugal effect, water or other liquid, or finely divided solid matter (such as shot) may be fed into the rotating casing during the operation. In the machine shown for carrying out this method, the flat band 41 is built up on a collapsable drum 34 which is detachably mounted between a pair of coned rings 30, 32. After assembling the bead wires 42, the edges of the band are clamped by rings 47, 48 and the drum 41 removed. The next operation consists in rotating the band whilst causing the edges 43 to approach one another. For this purpose, the ring 32 is connected to the outer ends of guide,- rods 11, the inner ends of which are connected to a spider 10 keyed to a sleeve 3 surrounding a shaft 1. A disc 12 secured to the outer end of the shaft 1 is connected to the ring 30, means being provided for axially moving the shaft along the sleeve 3 to effect the approach of the edges 43 of the band. The inner end of the shaft 1 is screwed through a sleeve 4 adapted to be coupled to the sleeve 3 through a thrust bearing 17 and clutch 15. Fitted to the sleeve 4 is a brake 25 the operation of which is controlled by a treadle 27. The sleeve 3 is driven from a motor 21 through a friction clutch 22 and a 3- speed reversible gear 20, and chain 18. In operation, the casing being under rapid rotation, the clutch 15 is temporarily withdrawn and the brake 25 gently applied. The retardation of the sleeve 4 with respect to the shaft 1 causes the latter to unscrew and travel in the direction of the arrow 29 to effect a corresponding movement of the inner edge 43 of the casing. The sleeves 3, 4 are again coupled and this sequence of operations continued until the rings 30, 32 meet, the (rotating) casing then having the form shown in Fig. 5. The motor is then unclutched and whilst the sleeves 3, 4 are still coupled the brake 25 is applied to stop the rotation of the casing which then assumes the form shown in Fig. 6. The rings 30, 32 are then clamped together by bolts 53 to permit removal of the casing for the vulcanizing or other finishing processes. If liquid (indicated at 49) has been used to increase the centrifugal effect, the internal pressure in the shaped casing may be adjusted by means of a valve 54. If solid material has been used the valve may be utilized for injecting air to maintain the desired internal pressure. Packing-rings 51, 52 are provided to make the necessary fluid - tight joints. Specification 214,704, [Class 87 (ii), Moulding plastic &c. substances], is referred to.
