Title: Improvements in or relating to alternating current electric switchgear
IPC: H02B1/00
Filed: 1940-03-11
Abstract: 539,484. Gas-blast switches; switchgear structures. REYROLLE & CO., Ltd., A., ALLEN, A., and ANDERSON, W. March 11, 1940, No. 4494. [Class 38 (v)] A gas-blast circuit-breaker opening to a predetermined short gap and a series-connected isolating switch device which subsequently opens automatically, are embodied in a duplicate busbar switchgear structure, preferably of the horizontal draw-out type, with the isolating switch device arranged to effect busbar selection, the circuit-breaker reclosing automatically whereby the circuit is reclosed simply at the isolating switch. The fixed part of the gear comprises, in each phase, socket-contacts A ... C connected to duplicate bars and an external circuit, respectively, and engageable by plug contacts E ... G on the movable part D and connected, respectively, to fixed isolating contacts E<2>, F<2> and a main circuit-breaker fixed contact G<2> The movable isolating plug-contacts E<3>, F<3> are interconnected by a conductor G<10> in connection with a cylinder G<7>, in which slides a movable circuitbreaker G' urged towards G<2> by a spring G<5> and movable to open circuit by fluid admitted to the back of a piston G<8>. Arcing tips P, P<1> are located against a discharge nozzle P<2> for the blast set up by the actuating-fluid, this fluid being replaced, on tripping of the circuitbreaker, from a reservoir N through a valve N<4> operated by the piston N<2> of a motor N<3>. The same fluid acts on the upper face of a doubleacting operating piston L<3> for the isolator, which piston is connected through lever L<1> and link L to a pair of levers H<6>, J‹ on shafts H', J<7>, but the levers are not released until the breaker is open and notch G<12> therein receives a member M<2> which, by means of a projection M<5>, engages a latch M co-pivoted with M<2> at M<3> to move it clear of J‹. Levers M<6>, J<6> are linked at H<5>, J<5> to floating levers H, J pivoted at one end to the respective isolators and at the other end to linkage H<1>, J<1> carrying cams H<3> J<3>. For busbar selection, a rod K is slid up or down to engage a recess H<4> or J<4> in one of these cams so as to couple up the associated isolator, closure of which locks the selector against further movement. To effect change-over on load, each lever H, J is linked at H<12> with a crank H‹ on a handactuated pinion H<10>, and the isolators are latched by latches R<1>, R coupled by a rod R<2> which can be released by an electromagnetic the circuit of which contains two parallel-connected switches in series with a press-button switch. One of the former is closed when the busbar coupler is closed and the other when both isolators are open, it being necessary to operate the pressbutton switch both for busbar change-over, provided the coupler is closed, and for making the circuit at the selected isolator after tripping, For the latter purpose, the isolators, at the end of their opening movement, are each adapted to operate a valve to reclose valve N<4> and enable spring G' to reclose the circuit-breaker.

Title: Improvements in the method of electrically welding high-speed steel to tool-shanks or foundations of iron or steel
IPC: B23K31/02
Filed: 1922-02-16
Abstract: 196,137. Schr÷der, E. Feb. 16, 1922. Tools. - High - speed steel, particularly that of melting point lower than the welding or melting point of the part to which it is to be joined, is electrically welded to tool shanks or foundations of iron or steel by forming a cavity in the foundation so as to reduce the sectional area thereof, inserting therein the high-speed steel, then fusing the high-speed steel by electric resistance heating, and then, after cooling, bending or severing the foundation at the joint. Foundation parts K, placed in contact, are formed with a cavity into which the highspeed steel S, which may be in the form of waste cuttings, is placed. The parts are then secured to the clamps of an electrical butt-welding machine. The increased resistance caused by the reduced area of the part K results in the melting of the part S. Oxidation may be prevented by fluxes such as borax. A piece k, Fig. 2, may be placed between the parts K to form the floor of the cavity for the high-speed steel S, and in addition pieces may be inserted to form the side walls. In another form the part K may be in one piece and formed with a cavity to receive the high-speed steel. The high-speed steel is exposed after welding by bending the foundation or severing the composite body by cutting or grinding.

Title: Tubular ice-making machine
IPC: F25C1/06
Filed: 1951-02-27
Abstract: 680,087. Ice-making. REFROIDISSEUR TREPAUD SOC. AR.L. Feb. 27, 1951 [March 1, 1950], No. 4724/51. Class 29 A machine for making tube-ice comprises a cylindrical casing 1 having a large central tube 2 and small ice-making tubes 7 mounted in tube-plates 3, 4, the cylinder being filled with water which is circulated up the tube 2 and down the tubes 7 by a circulator 18 driven by a motor 20, the ice-making being effected by cold brine or refrigerant entering by a pipe 5 and leaving by a pipe 6 and the harvesting being effected by relatively warm brine or refrigerant entering by a pipe 5<SP>1</SP> and leaving by a pipe 6<SP>1</SP>. The freezing or warming fluid flows in a helical path defined by baffles 8 in the annular space arranged as described in Specification 457,732. The upper and lower parts of the annular space are separated from the central part by plates 3<SP>1</SP>, 41 so that freezing fluid cannot exchange heat with the ends of the tubes 7 but the harvesting fluid flows, by connecting pipes 511, 6<SP>11</SP>, through the end and central parts in series. Filling connections 13, 14 for the water to be frozen are provided and the bottom 15 is removed for harvesting. To prevent reverse circulation of the water, a non return valve 17 is fitted at the bottom of the tube 2. As shown in Fig. 3, brine from a refrigerating unit is circulated by a punch 31 through open valves 24, 23, pipe 5, the annular centre part of the ice making unit and the pipe 6 to effect the freezing. During harvesting, valves 23, 24 are closed and valves 25, 26 opened so that pump 31 withdraws warm brine from a store 27 and circulates it through pipe 5<SP>1</SP>, the lower part of the annular space pipes 5<SP>11</SP> and 5, the central and upper parts of the annular space and pipe 6<SP>1</SP> back to the store 27. The store 27 can be heated by either or both of coils 29, 30 through which pass the water passing to the freezing unit and warm condensatel for the refrigerating system including the brine cooler 22, respectively. In a modification, Figs. 2 & 4 (not shown), the water circulation is downwardly in the tube 2 and upwardly in the ice-making tubes 7. The non-return valve 17 is omitted. The freezing and harvesting fluid circuits are separate and each have a pump, the heating coils 29, 30 being omitted. After harvesting, the freezing unit is re-charged with water which heats up the harvesting fluid which has been chilled during the harvesting. This fluid is then pumped into its store and the freezing-fluid pump is started.

Title: Improvements in or relating to the manufacture of tire beads
IPC: B29D30/48
Filed: 1956-02-16
Abstract: 790,883. Rubber-coating tyre bead cores by extrusion. NATIONAL-STANDARD CO. Feb. 16, 1956 [March 3, 1955], No. 4855/56. Class 87(2). [Also in Group XXXIV] Two or more tyre bead rings are formed simultaneously by feeding at least two bead wire tapes 1, 2 in spaced side-by-side relation through means, such as an extruder 20, which coats the tapes with rubber to form a single ribbon having twice the width x of rubber between the tapes as there is between the wires of each tape, the ribbon being subsequently wound spirally to form a ring, Fig. 4, which is separable medially of the spacing between the tapes into separate bead rings. As shown, the tapes 1, 2 each comprise four parallel wires 4 held together by a light filling or weft wire 5 and are drawn from spools 12 through a preheater 17 to a screw-acting tubing machine 18 where it passes through a die head 20 to be rubbercoated. The die head comprises two sections 21, 22 clamped together by a U-clamp 24 and having parallel slots therein, Fig. 11, on each side of the die chamber 26 to receive baffle plates 28, 28a and 30, 30a. The baffles 28, 28a, Fig. 13, are on the entry side of the die chamber and define side by side slots 32 spaced by a web 33 to position the tapes 1, 2. The baffles 30, 30a on the outlet side of the die chamber define slots 34 spaced by a web 35 which does not, however, prevent flow and adherence of the rubbercoating at the adjacent edges of the tapes on emergence from the baffles 30, 30a. Where weftless tape is used, the wires being drawn from a fan-wise arrangement of spools 12, the inlet baffles define spaced sets of spaced apertures 39, Fig. 14, for the separate wires. The adhering rubber-coated tapes form a single ribbon which is passed through a cooler 44 to a festooning unit 46 and thence between a guide roll 50 and a pinch roll 68 which has a rib 69, Fig. 8, to cleave into the rubber between the tapes. The rib 69 on the roll 68 is fed with a tack reducing agent, such as paraffin, from a reservoir 70. The ribbon is then guided round a roll 80 and over a bend-producing roller 82 to a feeding unit 88 and thence to a bead winding drum 90. The end of the ribbon is held to the drum by a clamp 89 and the ribbon is pressed against the drum surface, by a spring-loaded roller 98 which also has a ribbed periphery to indent each convolution of the wound ribbon along the line previously impressed by the roll 68. The ribbon is severed on completion of the winding by a knife 92, and the composite ring is ejected from the drum by ejector fingers 95, the drum surface being relieved by grooves 105 to prevent any tendency for the ring to bind thereon due to its width. U.S.A. Specifications 2,151,306 and 2,190,805 are referred to.

Filed: 1955-02-18
Abstract: 765,532. Glass, manufacture of. PITTSBURGH PLATE GLASS CO. Feb. 18, 1955 [March 12, 1954], No. 4906/55.. Class 56 [Also in Group XII] A glass strip is passed continuously to a lehr by roughing rollers, and the waste caused by the development and extension of longitudinal cracks in the strip is minimized by veering the crack towards one edge of the strip and accelerating the thus separated part so that it leaves the lehr in spaced relation to the main oncoming strip. Observation windows are provided along the lehr, so that the operator may select a position on the glass strip ahead of the developing crack, and veer the crack towards an edge by lifting said edge with a rod. The glass is received from the roughing rollers on conveyer rollers 22, 24, driven by a shaft 30. The rollers 24, at the exit end of the lehr are driven, independently of the rollers 22, through worm and other gearing 44, a clutch controlled by a lever 38 being provided. A chain 50 trained over sprockets 54 on the roller shafts is driven by a sprocket 48 which is a little larger than the corresponding sprocket 49 driving the rollers 22 so that the rollers 24 rotate faster than the rollers 22. If no crack has appeared, the rollers 24 slip on the underside of the glass which has hardened sufficiently to remain undamaged. If a cracked piece is separated from the main stock, it is accelerated by the rollers 24 away from the main stock. Alternatively the sprockets 48, 49 may be of the same size, and the acceleration is produced by a change speed gear in the transmission between the shaft 30 and the the sprocket 48. In this case, the rollers 24 are speeded up only when this is necessary to remove a separated piece of glass.
