Title: Improvements relating to air-blast switches
IPC: H01H33/70
Filed: 1948-05-14
Abstract: 691,169. Air-blast switches. CZECHOSLOVAK HEAVY ENGINEERING WORKS, NATIONAL CORPORATION, and GROSSE, V. May 14, 1948 [May 15, 1947], No. 13421/52. Divided out of 13343/48. Class 38 (v) An air-blast switch has main current-interrupting contacts 1, 2 in parallel with a resistor 5 in series with an auxiliary spark-gap-type interrupter 3, 4 at which arc extinction is delayed with respect to the opening of the contacts 1, 2, and additional current-carrying contacts 33, 34 in parallel with the main interrupting contacts 1, 2, the contacts 33, 34 being disposed nearest to, and the spark gap 3, 4 farthest from, the supporting insulator 11 of the switch so as to minimise the stresses acting on the insulator due to electrodynamic forces. When the switch is opened, the contacts 33, 34 are initially opened by the air blast, the contacts 1, 2 being held closed by pneumatic means (not shown) until the contacts 33, 34 are open. The air-blast acting on the contact 1 then opens the contacts 1, 2, a slide-valve (not shown) associated with the contact 1 admitting compressed air through pipes 16, 17 to the extinguishing chamber 8 of the auxiliary interrupter when the contacts 1, 2 are open. The arc drawn between the electrodes 3, 4 is extinguished by the blast through an insulating nozzle 25, this blast exhausting into the main exhaust chamber 31 of the switch through a pipe 30 formed as an ejector to avoid the return flow into the auxiliary interrupter of blast gases flowing through the nozzle contact 2 of the main interrupter. Air flowing from the chamber 8 through a pipe 21 into a cylinder 22 opens an isolator 6, 6b. If automatic reclosing of the circuit controlled by the switch is required when the air blast is shut off, the isolator 6, 6b is maintained closed throughout the operation of the switch by the application of compressed air through a pipe 41 to the closing cylinder of the isolator.

IPC: B63B3/14
Abstract: 136,810. Cast Steel Ship Corporation, (Assignees of Hill, M. F.). Dec. 19, 1918, [Convention date]. Framing.-Ships are constructed of steel castings of the form shown in Fig. 43 consisting of an outer shell portion 153, longitudinal ribs 154, and transverse ribs 152, the longitudinal ribs having a bulb edge 151. The various edges are formed as shown in Fig. 44 to permit welding. The Specification describes in detail the complete design for a ship embodying the sections shown, and in which the shell, decks, tanks, &c. are all constructed of these castings welded together. The sides of the ship are straight in transverse section, and, in some parts of the ship, the frames and beams are inclined to permit the use of these standard sections. In casting the sections, the mould is inclined, and the metal is supplied through a gate 155 to the bulb, the size of which is largely determined by the necessity of maintaining a proper flow of metal to enable the upper part 153 to be cast before the bulb is chilled. In a modified form of section, the overhanging parts are joggled to enable the adjacant edges to be riveted. The rivets are merely. inserted and then welded in place. The joint may also consist of studs on one part fitting and welded into holes on the other part.

Abstract: 893,650. Two-foci straightness testing devices. AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY, MINISTRY OF INTERNATIONAL TRADE & INDUSTRY. April 30, 1958 [Oct. 18, 1957; Feb. 4, 1958(2)], No. 13809/58. Class 97(1). An optical element in the form of a transparent plate having deposited on it, by vacuum deposition or photographic means, a radially-varying distribution of absorbing and/ or transparent phase-retarding material (for example as indicated, respectively, by 2 and 3 in Fig. 3), gives rise to a pupil function in an associated collimator system which provides Strehl intensity maxima at two separated axial positions, so that there are, in effect, two foci, the said optical element and collimator being comprised in a straightness tester whereby the images of two targets located at the regions of the Strehl maxima may be observed in superposition by an observing telescope. As shown in Fig. 5(1) two axially separated targets A and B are viewed through a telescope T, E via a two-foci element F mounted on a support which traverses a surface M. Vertical movement of the axis of F from the line defined by A-B causes relative vertical displacement of the superposed images of A and B. In the arrangement of Fig. 5(II), the autocollimator C serves as the telescope objective, a half-silvered mirror N directing light into the eyepiece E. Two two-foci elements may also be used. The targets may be in the form of knife-edges (Fig. 6) the cross-over point being displaced horizontally as the images are relatively displaced vertically.

Patent GB-877906-A (GB)
Title: A process for the manufacture of cyanuric chloride
Inventor: NIWA TOSHIO
Filed: 1958-05-01
Abstract: Cyanuric chloride is prepared by passing hydrogen cyanide gas having a water content of less than 0.5% and chlorine gas through a bed of activated carbon catalyst at a raised temperature.  The reaction is effected with a mol ratio Cl2:HCN 1.00 to 1.10, at 300-450 DEG C., and space velocity 40-120 hr.  The product is condensed from the effluent and any cyanogen chloride in the product gas is recycled to the process.  The gases are dried to less than 0.5% water content by calcium chloride, or silica gel. The activated carbon may be prepared by treating a carbonized organic substance at above 800 DEG C. with a stream of water vapour, carbon monoxide, or carbon dioxide, or by heating the substance with metallic chlorides, e.g. ZnCl2.  The activated carbon should be dehydrated by heating at 700-1000 DEG C. under vacuum, e.g. less than 50 mm. Hg., or in an inert gas, e.g. CO2 or N2, cooled, and then saturated with cyanuric chloride at 200-300 DEG C.  The resulting carbon catalyst of 3-10 mesh is filled into a tower.
