Title: Improvements in or relating to gas blast electric circuit interrupters
IPC: H01H33/90
Filed: 1959-03-04
Abstract: 858,791. Gas-blast switches. WESTING- HOUSE ELECTRIC CORPORATION. March 4, 1959 [March 7, 1958], No. 7513/59. Class 38 (5). In a gas-blast circuit-interrupter having a pumping cylinder in the arcing chamber, the differential piston thereof has a lost-motion connection with the moving contact which has a passage venting into an orifice passage in the piston when the contacts are closed and which is closed after the lost-motion has been taken-up during contact separation. The interrupter housing, which preferably contains sulphur hexafluoride, comprises two cylindrical insulators 2, 3 secured and sealed to a base 27, connector plates 6 and 19 and a cap 17. The moving contact 7 passes through an opening 8 in a boss 59 on the plate 6, and the boss has threaded thereto an insulating cylinder 57 which receives one end of the differential piston 54. The piston has lost-motion on the end of the contact 7 limited by a recess 63, and its larger end is provided with a piston-ring 61 engaging the inner wall 60 of the insulator 2. A bracket 10 on the cap 17 supports the fixed contact 9 which is biased towards the moving contact by a spring 11. When the contact 7 is moved downward the contact 9 moves with it initially but the piston 54 is not moved until the lost-motion 63 is taken up. The contact 7 and piston 54 then move together and under heavy current conditions the pressure on the upper large surface 55 of the piston due to the arc assists the external operating-mechanism in compressing the gas in the cylinder 57 which is forced through passages 65 to the arcing region 52. A valve 70 is provided so that the gas in the cylinder 2 does not oppose its movement when light currents are being interrupted. Passages 49, 50, 51 in the contact 7 are sealed by the piston when the contact is moved downward but during closing movement they are opened and allow gas to flow. The plate 6 is connected to the contact 7 by rollers as described in Specification 847,968, and the contact is moved by links 34, 38, the former carrying rollers 35 in slots 36 in the base 27 and the latter being keyed to a shaft 39 rotatable by an arm 40 outside the interrupter. Specification 736,090 also is referred to.

Abstract: 1,263,141. Pelleting carbon black. COLUMBIAN CARBON CO. 13 Feb., 1969 [15 Feb., 1968], No. 7945/69. Heading B5A. [Also in Division C1] Carbon black particles, e.g. furnace black for compounding with rubber, is formed into pellets by spraying liquid, e.g. water, binder solutions, oil emulsion, or oils, from a rotatably adjustable tube 10 provided with a jet or jets 11 into particles which are simultaneously agitated and conveyed along a stationary cylindrical conduit 2, between a particle inlet 3 and a pellet outlet 4, by the action of members 8 extending either radially or at an inclination from a rotated shaft 5. The members 8 may either be helically staggered or located in the same radial planes along the shaft 5. The tube 10 is mounted for rotation, into a position wherein it is locked by a locking screw, whereby the jets 11 may direct the spray parallel to the radial plane of the shaft 5, or preferably at right angles thereto or at an intersecting angle within 45 degrees on either side of the perpendicular whereby the members 8 assist in distributing the liquid spray uniformly in a circumferential direction. The jets 11 extend longitudinally along the wall of one or more of the tubes 10 which project radially into the conduit 2. The tube 10 may comprise a series of circular jets 11, or a single or a series of slit type jets. A plurality of tubes 10 may be employed which extend to different depths into the conduit 2 and are circumferentially or longitudinally distributed therein. The particles may extend throughout the crosssection; or form an annular zone within the conduit 2. The jets are generally provided adjacent the particle inlet 3, but may in addition be provided further downstream. The discharged pellets are passed to a conventional pellet polisher and/or conventional dryer to remove excess liquid. Examples are given illustrating the higher mass strength, as determined by A.S.T.M. D1937-62T; and lower crush strength (as determined by the load required to crush 500 micron diameter pellets) obtained over the prior art processes.

Abstract: 803,946. Vehicle supply systems. WIPAC DEVELOPMENT, Ltd. March 7, 1956 [March 18, 1955], No. 7999/56. Class 38 (4). A battery-charging circuit for use in a motor cycle comprises a three-pole switch 10 for regulating the output of an alternator 27 under three conditions of a load which includes head lamp 42, rear lamp 39 and parking lamp 41. A battery 34 is adapted to be charged from the alternator through rectifier 31, and resistors 37, 38 are arranged to dissipate part of the alternator output, the switch 10 controlling the amount of resistance in circuit in accordance with the magnitude of the load. In the " off " position of the switch 10 excess current generated by the alternator 27 is diverted from the battery to earth through resistor 38. In another position of the switch, the lamps 39, 41 are switched on, and excess current is dissipated to earth through resistor 37. When the switch is set at a further position, lamps 39, 42 are illuminated and neither of the resistors are included in circuit. Several modifications, Figs. 2-6 (not shown), relate to different methods of controlling the impedance for dissipating part of the alternator output. In one arrangement, each resistor is connected to a different lead from the alternator to the input terminals of the rectifier, the other ends of the resistors being selectively connectible to earth. The resistors may be connected in series with the battery, either on the input or output sides of the rectifier. A tapped resistor may be connectible across the output terminals of the alternator, the switch 10 being operable to select the effective tapping in accordance with the load on the machine. In another arrangement, the resistors 37, 38 are replaced by a tapped inductor in series with the battery on the input side of the rectifier.

Abstract: <PICT:1113359/C1/1> <PICT:1113359/C1/2> To deposit glass particles 30 on an object 28, the object 28 is supported above a fluid 27 containing the particles 30 in a container 12, the container 12 is centrifuged at such a speed that the object moves below the fluid, then at a speed so that particles 30 are deposited on the object 28 and then the speed is reduced so that the object moves above the fluid level before centrifuging of the container 12 is stopped. The object 28, such as a silicon wafer, is supported on a platform 26 having an annular flange 36, a spring 24 being secured to a loop 32 on the platform 26 and extending to the bottom of the container 12. In the compressed state, the spring 24 is contained by the flange 36. The containers 12 are mounted in carriers (14) as in Specification 992,044 which move from a vertical position to a horizontal position at about a force of 6 G and the weight of the spring 24, the platform 26 and wafer 28 and the strength of spring 24 are chosen so that the spring collapses at about 12 G.  The particles 30 start to deposit at about 64 G and normally the centrifuge is operated for about 1-2 minutes at a speed to give a force of 1000-2500 G.  As the centrifuge is slowed, the spring 24 operates to move the wafer 28 out of the fluid 27 before the carrier (14) moves out of the horizontal position and unevenness of coating is thereby prevented. To assist removal of the wafer 28 from the platform 26, a number of holes 38 and edge cut-outs (40) are provided in the top disc shown, or the platform may consist of the flange 36 with a loop to retain the spring 24 with or without one or more cross wires.  Three guide pins 34 are provided between the flange 36 and the container 12 and they also assist in retaining the wafer 28.

Abstract: 565,794. Condensers. BURGESS, A. F. (Zenith Radio Corporation). May 21, 1943, No. 8113. [Class 37] 'A variable condenser comprises two coacting parts, one or both being modified so as to produce owing to their relative movement, a rate of frequency change to be maintained relatively low and substantially uniform in two spaced parts of the frequency band covered, and to be made relatively high in that part of the frequency band between the spaced parts. In the examples, this is effected by suitably shaping the rotor plates, Fig. 2, or the stator plates, Fig. 5. In these cases a substantial change in capacity is effected by each movement of rotation when part A in the rotor, or A<1> in the stator, first becomes operative ; with sections B and B<1>, the change is low, sections C, C<1> the rate of change is high, D, D low and E, E<1> high. Modified rotor plates may be used with modified stator plates. The intention is to space out the timing in those parts of a short-wave band that are crowded.
