Title: Multi-phase circuit breaker
IPC: H01H71/58
Filed: 1964-04-03
Abstract: 1,058,722. Automatic circuit-breakers. I-T-E. CIRCUIT BREAKER CO. April 3, 1964 [June 5, 1963], No. 13864/64. Heading H2B. An overload circuit-breaker contained in a moulded insulating case has a handle 21 extending through an aperture in one surface of the case, the line and load terminals 42, 52 of all phases extending through apertures in a second surface and mechanical mounting devices 40 extending from a third surface of the case. The case is formed with three compartments A, B, C, each housing the contacts and tripping mechanism of one phase and a fourth compartment D housing the common operating members. Each phase (Fig. 4, not shown) has a double-armed contact lever 45 resiliently mounted at 54 in a frame 63 and biased into engagement with a fixed contact 44 by spring 62 while its other end 76 is latched by a lever 67 also pivoted in the frame 63. The frame 63 also has portions 63A forming the poles of an electromagnet energized by the current through a bimetal 49 to attract an armature 199 on the lever 67; the bimetal also acts on lever 67 to release the latched end 76 of contact 46. The lever 67 also acts on an arm 103 of a common trip bar 100 to release the other phases. The contacts are reset by depressing the operating handle 21, cam surfaces 151 thereon engaging cam surfaces 152 on the contact levers 46. The trip bar 100 is provided with a fourth arm 104 (Fig. 8, not shown) located in the compartment D. In the closed condition it latches a lever 110 against anticlockwise movement by a spring 116 which also biases a second copivotal lever 125 clockwise against a stop 145 on lever 110. A leg 140 of handle 21 has a projection 122 engaging an arm 114 of lever 110 to limit the upward movement of handle 21 in the closed condition. When the breaker is tripped arm 104 releases lever 110 and permits handle 21 to rise under its biasing spring 38 to indicate the tripped condition. The breaker can be manually tripped by depressing handle 21 until a surface 142 thereon engages a projection 143 on lever 125 pivoting lever 110 until its nose 111 rotates the arm 104 of the trip bar 100; full depression of handle 21 is prevented by lover 110 striking part of the housing 22<SP>1</SP>. When handle 21 is subsequently depressed to reset the breaker an abutment 161 on leg 140 engages a projection 149 on the 110 lever moving it clockwise into engagement with latching arm 104; the lever. 125 is arrested early in its travel by the surface of leg 140 so that the tripping action cannot occur. A modified arrangement of the terminal structure is described (Figs. 19, 19A, not shown) enabling the breaker to be used with the panel board described in Specification 1,058,723.

Title: Improvements in or relating to Electrolytic Cells, adapted for the Manufacture of Caustic Alkali from Sodium Chloride.
Inventor: STATHAM NOEL
Filed: 1917-09-26
Abstract: 118,355. Statham, N. Sept. 26, 1917. Alkalies, obtaining; diaphragms; supporting electrodes; electrolytes, circulating.-A diaphragm between an anode chamber and an empty cathode chamber allows passage of sufficient electrolyte to prevent back diffusion of caustic soda. It may be faced, on the discharge side, with less porous material arranged so as to render the lower parts of the diaphragm less permeable than the upper parts. Uniform percolation throughout the diaphragm can thus be obtained. The body of the diaphragm 16 may be of asbestos board or paper, and the facing 17 of finer asbestos, incorporated with or applied to the body, and either stepped or steadily increasing in thickness downwards. Percolation takes place preferably at such a rate that, with concentrated brine in the anode compartment, the cathode liquid may contain about equal proportions by weight of alkali and salt, say, 11 parts of the former to 10-11 of the latter. A direct overflow from the anode compartment of about 1/10 litre of brine per sq. ft. of diaphragm surface may be provided for. The perforated cathodes may be sustained by perforated ribs 9 on cover-plates 8. Reference has been directed by the Comptroller to Specifications 5197/93, 20889/03, and 27830/07.

Title: Ionization gauge for the measurement of low pressures
IPC: H01J41/06
Filed: 1958-05-06
Abstract: 889,947. Discharge apparatus. NATIONAL RESEARCH COUNCIL. May 6, 1958 [May 7, 1957], No. 14461/58. Class 39(1) An ionization manometer arrangement designed to reduce X-ray emission from the electrodes and the resulting photoelectric emission from the positive ion collector and envelope walls comprises a chamber 27 housing a hollow main cathode 11, a filamentary or other slender anode 10, and an auxiliary cathode 16 which is separate from the main cathode 11 and which has a surface lying closer to the anode 10 than do any parts of the main cathode 11, the main cathode 11 and the anode 10 defining between them an annular ionization zone 22 which is partially closed at opposite ends by cathode parts to trap electrons in the ionization zone 22. The arrangement shown comprises an anode wire 10 coaxial with a cylindrical main cathode (positive ion collector) 11 having end plates 12 and 13 with large central holes 14 and 15, and two auxiliary field emission cathode discs 16 and 17 closely spaced from the end plates of the main cathode and having small central holes 18 and 19. A high positive potential, e.g. 5 to 10 KV. is applied to the anode 10 with respect to the grounded cathodes 16 and 17, and a magnetic field is directed parallel to the anode 10 by pole-pieces 20 and 21. Electrons emitted from the edges of the holes 18 and 19 by field emission are drawn into the cathode cylinder 11 and orbit about the anode 10 before being collected by it. Positive ions are collected by the main cathode 11 and the current is indicated by a meter connected between the cathode 11 and ground. Photoelectrons emitted by the main cathode 11 due to X-rays from the anode 10 orbit near the wall of the cathode 11 before returning to it. The net liberation of photoelectrons from the main cathode 11 does not compare with the positive ion current thereto until a gas pressure below about 10<SP>-14</SP> mm. of mercury is reached. The main cathode 11 is preferably made of gauze and the end plates 12 and 13 are of mesh or are pierced to allow free passage to the gas. The auxiliary cathode discs 16 and 17 may be provided with apertures for the same purpose. A point or spike auxiliary cathode may be used in place of the discs. In a modified arrangement, Fig. 3, the field emission cathodes 16 and 17 are formed from a single sheet of metal bent to form a box-like shield, and are provided with cylindrical parts 35 and 36 which intercept X-rays from the anode 10 and also shield the end plates 12 and 13 of the main cathode 11. The holes 14 and 15 in the discs 12 and 13 provide a clearance of about 1 mm. from the parts 35 and 36. The manometer is stated to act as an efficient ion pump.

Title: Improvements in tools for twisting wires together
IPC: B21D11/14
Filed: 1925-06-04
Abstract: 235,199. Stetson, W. D. June 9, 1924, [Convention date]. Twisting wires together.-A wire-twisting tool for linemen's use consists of a handled head in which is removably mounted a die provided with a toothed periphery so that it can be rotated by a reversible ratchet mechanism. The upper part of the head, consisting of upper plates 14 and spacer 17, is pivoted at 18 to the lower part which consists of lower plates 14 and spacers 15, 16 and is secured to slotted plates 3 connected to the portion 2 of the handle 1. The parts are held in closed position by a spring latch 20. The twisting die 23, 24, also formed in two parts, has annular ribs 26 to engage grooves in the head and has a toothed periphery 10 with which engage pivoted pawls 8, 9 normally pressed into contact with the teeth by a spring 13. The pawls may both remain in engagement with the teeth or one or both may be moved out of contact with the teeth by slidable U-shaped members 6, 7 having pins 5 passing through slots 4 in the plates 3, so that either of the pawls may remain in engagement for ratchet-operating purposes, or so that both may be kept out of engagement in order that the head may be rotated relatively to the die to bring the parting surfaces into line. Each part of the die has a lug projecting into a recess in the other part and secured together by grooved pins 31 held in position by spring-pressed members 35. A series of dies having apertures 25 of various sizes to suit jointing tubes of various sizes are used, and a series of tools of different sizes may also be used. The upper part of the head is first moved on its pivot 18 prior to placing the tool over the tube, and is then closed and held in position by the latch 20. The pins 31 are then pushed in until the grooves 37 engage the members 35 to lock the parts of the die together and one of the pawls is then disengaged. A second tool is placed at the other end of the tube, and its other pawl is disengaged. The wires to be joined are passed through the two chambers of the tube and twisting of the tube and wires is then effected by rotating the tools in opposite directions by the ratchet mechanisms.
