Title: Improvements in or relating to battery grid castings
IPC: B22D25/04
Filed: 1948-02-23
Abstract: 652,288. Making battery plates; casting; shearing. WINKEL, H. C. Feb. 23, 1948, No. 5331. Convention date, June 24,1948. [Classes 83 (i), 83 (ii) and 83 (iv)] A battery grid casting having post-forming lugs 89 extending laterally in opposite directions from a duplex grid structure is characterized by a pair of positioning lugs 15a extending forwardly from the front edge beyond the expected forward fin or flash for engaging positioning-means on a machine for the trimming of the flash and positioning lugs from the casting. The Specification as open to inspection under Sect. 91 comprises also apparatus for casting and trimming. The plates are cast in a mould comprising a fixed part 2 having projecting pins 41 on which slides the second part 3 under the control of a yoke 48 resting in a notch 49 formed in posts 50 projecting from the movable part. When the mould parts are closed, molten metal is supplied by a reciprocating pump to a reservoir 19 and overflows into the mould. On the return stroke of the pump piston, the closing of the outlet valve is delayed so that some metal is drawn back from the reservoir 19 to prevent metal overflowing while the mould is open. Before the mould is opened a drip catcher 38 is moved into the position shown in full lines in Fig. 5 (Cancelled). On opening the mould, the grid falls on to an arcuate slide 4 and is delivered in a horizontal position to a conveyer 5 which carries it to a trimming device comprising a pair of stationary trimming edges 9 and 10 with which co-operate a pair of shearing blades carried by a reciprocating head 13. The entry of the grid into the trimmer is delayed by a stop-plate 15 until the head is near the top of its stroke. Within the trimmer, the grid is positioned by a pivoted stop-bar 17 which on the upward movement of the head is raised by a hook 96 to allow the trimmed grid to pass on to a conveyer 8. The movements of the mould part 3, drip catcher 38, metal pump, trimmer head 13 and the conveyers 5 and 8 are all derived from a driven shaft 40. The conveyers are driven by chains 72 and 87, both of which pass round sprockets on a shaft 74 which also carries a crank for reciprocating the trimmer head 13. A cam 41a on the shaft 40 operates an arm 42 pivoted on a rock-shaft 43 and connected by a trunnion block 41 with a connecting- rod 45 secured to the mould operating yoke 48. A certain amount of lost-motion is provided by a spring 54. An arm 56 secured to rotate with the rock-shaft 43, operates the pivoted dripcatcher 38. The pump is operated from a cam 60 through a bell-crank lever 61a, connecting- rod 63 and a rock lever 24. This subjectmatter does not appear in the Specification as accepted.

Abstract: 197,087. British Thomson - Houston Co., Ltd., (General Electric Co.). Feb. 23, 1922. Soldering-irons.-The bit of a soldering-iron is carried by a rod of resistance material, such as carbon, which is in electrically conducting relation with the useful portion of the bit, the rod being connected to one terminal of an electriccircuit and the work to the other terminal. A carbon rod 13, clamped in the bore 18 of a metallic member 17, passes through the bore 12 of the bit 11 into a tapered bore 12<1> therein, the end of the rod being similarly tapered to fit the bore and to concentrate the heating effect at this end. The end of the rod is also provided with four grooves 24 for increasing the heating effect. The bit is secured to the rod by screws, and between the rod and the bore 12 is an insulating jacket 16 to provide electrical insulation and also to prevent the access of air to the heating point and thus to prevent oxidation. The sleeve projects beyond the bit so as to insulate it from the member 17. A conductor 22 connected with one terminal of a transformer is secured by a screw 23 passing through the handle 21 to a hollow enlarged portion 19 of the member 17. The other terminal of the transformer is connected by a clip to the work so that the current is on only when the bit is in contact therewith.

Title: Improvements in or relating to linear accelerators for charged particles
IPC: H05H9/02
Filed: 1954-02-23
Abstract: 758,854. Particle accelerators. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Feb. 23, 1954 [Feb. 23, 1953], No. 5353/54. Class 39 (1). A travelling-wave linear accelerator comprises a system of delay lines S1, S2 ..., Fig. 3, facing a plane electrode or system of plane electrodes A, and the beam F travels in crossed electric and magnetic fields E, B. In order to prevent the beam falling in to the delay lines the ratio E/B is varied progressively or step by step. A series of electromagnets provide transverse fields decreasing successively. The transition spaces between the lines S1<SP>1</SP>A, S2<SP>1</SP>A ... are devoid of magnetic field. The delay lines S1, S2 ... increase successively in length, and so do the magnets. The delay properties of the lines correspondingly vary with increase in velocity. The magnets may be offset to stabilize the beam path. In Fig. 6 successive lines S1, S2, S3 are staggered. The electron gun includes a Wehnelt cylinder 2, an accelerating anode 3 at a potential V o , and two semi-cylindrical electrodes 4 at potential V o , and 5 at potential 2V o . In Fig. 7, for accelerating protons the electrodes Al, A2 ... connected alternately to opposite terminals of a high frequency transformer simulate delay lines. The magnetic field is decreased progressively by gradually increasing the gap between a pair of pole-pieces extending the length of the accelerator. The pole-pieces are fed by a succession of electromagnets. The delay lines, Figs. 3 and 6, may be fed from a single or individual wave generators. Standing wave or forward or backward space harmonic operation may be used.

Abstract: 800,190. Identifying railway vehicles. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 15, 1956 [Feb. 23, 1955], No. 5478/55. Class 105. [Also in Group XL (b)] Vehicles are identified as they pass an indentification post by means of a pattern of a plurality of similar or different radio-active transmitters carried by the vehicle which affect radiationresponsive apparatus or reading heads fixed at the post and adapted to provide signals corresponding to the radiation pattern of the sources as they pass by and also adapted, if desired, to provide a single signal for vehicle counting purposes. The sources may, e.g., be attached preferably to the unsprung portion of the vehicle in a verticle line and can be read from a plurality of reading heads equal to the maximum number of sources which may be encountered and arranged with the same vertical spacing, as the sources or, as shown in Fig. 2, the sources 3 may be arranged on the vehicle 1 in a horizontal line allowing of sequential reading of the sources if a single reading head 5 is employed or simultaneous reading may be effected if there is employed a number of reading heads 5 equal to the maximum number of sources arranged to have the same configuration as the source 3, and arranged to be read at the instant the sources are opposite the heads. The horizontallyarranged reading-heads 5 in the form of Geiger- Muller tubes A1-A5, Fig. 4, are arranged in a radiation absorbant, e.g. lead, casing 4, Fig. 2, and are provided with narrow apertures so as to restrict the angle of radiation reception to narrow limits. The outputs of these tubes A1-A5 are amplified in amplifiers B1-B5, their outputs being fed to gating devices C1- C5 which are opened by the signal amplified in amplifier B6 from a Geiger-Muller tube A6 affected by a radio-active transmitter arranged as at 7, Fig. 2, below the horizontal row of transmitters 3 when the latter are instantaneously opposite the tubes A1-A5. The outputs from the gating devices are fed to storage stages D1-D5 or signal utilization devices. The radio-active sources may comprise Sr90+Y90 or else Csl37. The identification information may be in binary code, the two forms of binary digit being indicated by the presence or absence of a radiation source or alternatively by the use of two distinct types of radiation source. For detection of beta-rays an open-ended window type counter such as the Applicant Company's halogen-quenched type B.12.H may be used. Sodium iodide crystals may be used to detect gamma rays.

Abstract: 1,022,469. Advancing mine roof supports. DOWTY MINING EQUIPMENT Ltd. Feb. 2, 1965 [Feb. 11, 1964], No. 5687/64. Heading F1P. An advanceable mine roof support 3, Fig. 2 (not shown) is released slowly by draining fluid through a line 19, an aperture 34 in a piston valve 26, a lever-actuated pilot valve 36 in parallel with valve 26 and through a line 22 leading to a main return line 23 and the prop is then released more quickly by the valve 26 being lifted from its seat 27 following the pressure drop across orifice 34 when the roof bar is clear of the mine roof the pressure drop across aperture 34 decreases which results in valve 26 closing and rate of release being slowed. If during advancement the roof bar re-engages the roof the resulting pressure build-up in valve chamber 29 lifts valve 26 to re-establish quick release of the prop. The pilot valve 36 is held open by a rod 39 when lifted by a lever 42 pivoted about its fulcrum by the rod 49 of a piston 47 subjected to main pressure supply from a line 12. The valve 36 is closed prior to resetting the prop by the lever being displaced by a record piston 52 when a valve 14 in a branch 13 of line 12 is opened by the conveyer advancing jack 5 at the end of its stroke.

Title: Improvements in web-renewing mechanism
Inventor: BENNETT THOMAS RICHARD
IPC: B65H19/18
Filed: 1955-02-25
Abstract: 823,207. Feeding webs. CRABTREE & SONS Ltd., R. W. Feb. 24, 1956 [Feb. 25, 1955], No. 5786/55. Class 100(1) In a web renewing apparatus which includes means to time the transfer of web supply from a running web to the web of a rotating replacement roll, the timing means is arranged to respond initially to the diameter of the running roll and when that roll is reduced to a predetermined diameter to change-over to respond to a linear measurement related to the length of web drawn from the roll, the apparatus including a device to initiate a web renewing operation and the timing means being arranged to render the device active when a predetermined linear measurement is made. As shown, a roll spider has pairs of arms 1, 2, 3 carrying rolls 5, 6, 7, the roll 5 being an expiring roll, the roll 6 a replacement roll, and the roll 7 a newly loaded roll. The roll 5 engages belts 8 driven through a pulley 9 by the machine being fed. A belt frame 12 carrying a pulley 11 swings about the axis of a pulley 10 to follow the decrease in diameter of the roll 5. When the roll 5 has been reduced to a predetermined diameter a lever 16 mounted on a shaft 17 rocks the shaft 17 to actuate a striker 30 on a trip arm 29, thus releasing a latch 27 which normally holds a roller 20 out of engagement with a roller 24. The roller 20 is pressed into engagement with the roller 24 by a spring 32, an arm 23 which supports one end of the roller 20 carries a control arm 39 which upon engagement of the rollers 20, 24, actuates a switch 40. Actuation of the switch 40 causes rotation of the roll spider about a shaft 4 to bring the replacement roll 6 into renewing position at a distance from the running web W predetermined by a limit switch, not shown. The actuation of the switch 40 also causes lowering of the belt frame 12 and positioning of a brush and knife assembly 15 .adjacent the web W. Rotation of the roller 20, effects through epicyclic gearing, not shown, within the roller 20, engagement of a second control arm 38 with a switch 41 after a predetermined length has been unwound from the roll subsequent to the actuation of the switch 40. The second switch 41 causes actuation of a brush 13 which deflects the web W into engagement with the roll 6 to splice the two webs together and then causes operation of a knife 14 to sever the web W. The assembly 15 is then returned by gearing 44, 45, 46 to its inoperative position, thereby causing a cam 47 on the gear 46 to actuate an arm 48 secured to the shaft 17 to move the roller 20 apart from the roller 24. Specifications 453,112, 478,578 and 616,162 are referred to.

Filed: 1928-02-24
Abstract: 285,884. Westinghouse Lamp Co.. (Assignees of Iredell, C. V.). Feb. 24, 1927, [Convention date]. Vacuum tubes; R÷ntgen-ray tubes.-A theirmionic electrode consists of a refractory metal having incorporated in it a metal of good electron emissivity and a small proportion of metal of the cerium group; preferably thoriated tungsten is used as the main body, but zirconium, uranium, or vanadium may be incorporated in molybdenum. The metal of the cerium group and the electron-emitting metal are present as oxides or reduced metal. With an addition of oxides of metal of the cerium group in the proportion of 0.5-4 per cent of the thorium oxide content to tungsten containing 1 per cent of thorium oxide, an increase in the emission over that of a thoriated tungsten filament of 10 per cent-40 per cent, and a much longer life of constant emissivity are obtained. In the preferred process tungstic oxide is mixed with a solution of thorium and cerium nitrates in such proportions that, on reduction, 1 per cent-2 per cent of the total content consists of thorium oxide, and cerium oxide is present in the proportion of 1-3 per cent of the thorium oxide content. After drying at 110 C. the mixture is crushed, sifted, and fired in a muffle furnace at 900-1000 C for three hours, to convert the nitrates into oxides. The. fired material is sifted and heated in a nickel boat in hydrogen at 1000 C. for two hours, in order to reduce the tungsten oxide, but without reducing the other oxides to any extent. The material is pressed into slugs and made coherent by heating in hydrogen to 1200 C. for 1-2 hours. Sintering is effected in a treating bottle through which dry hydrogen is passed, by passage of current increasing to about 90 per cent of the fusion current. The sintered slugs are swayed and drawn into wire in the usual manner. Small wires are activated by flashing in hydrogen and larger wires by flashing in a hydrocarbon gas. Reference has been directed by the Comptroller to Specifications 182,817, 216,840 and 282,539.
