Title: Pneumatic dispatch-carrier-separating arrangement in pneumatic tube systems
IPC: B65G51/22
Filed: 1963-10-04
Abstract: 1,008,436. Pneumatic dispatch apparatus. STANDARD TELEPHONES & CABLES Ltd. Oct. 4, 1963 [Oct. 8, 1962], No. 39168/63. Heading B8A. In a separating device for the carriers of a pneumatic tube system, a pair of conveyer tube branches 5, 6 on opposite sides of a valve flap 7 in the tube 1 are connected alternately to pressure and suction sources whereby the leading carrier of a train is first drawn by suction as at 10 through branch 5 to a position between the branch 5 and valve 7 and is then separated and blown through the valve 7 to a position beyond the branch 6 by pressure applied as at 12 through the branch 5 and suction applied at the branch 6. The branches 5, 6 may be connected to the opposite sides of a reversible blower G. The speed of approach of the carrier train is reduced by permitting the escape of air from the main line 1 through a third branch 2 which is provided with controllable throttle 4a and a non-return valve 3. A controllable throttle valve may also be provided in the branch 5. A contact 9 detects the presence of a carrier in front of the valve 7 and controls the reversal of the blower G. A timing switch (not shown) cancels the reversal to dispatch the carrier through a flap, valve 8. In a modification (Fig. 2, not shown), the branch 2 and an additional branch beyond the valve 8 are connected to atmosphere or to a separate blower via throttle valves to control the braking.

A lightning arrester of the type comprising an assembly of spark gaps and resistor blocks contained in a tubular housing has the housing shaped so as to form channels whereby any gases evolved therein during operation are conveyed to the ends of the arrester, which ends are formed by frangible diaphragms which rupture upon excess gas pressures being formed in the housing. The assembly of spark gaps and resistor blocks 16, 17, 14, 15 is generally circular in cross-section and is contained in a tubular porcelain housing 11 the internal bore 12 of which is of non-circular cross-section, the projections 23, 24, 25 centering the spark gap/ resistor block assembly whilst the grooves 20, 21, 22 form passages along which any gases evolved during operation of the arrester are conveyed to the ends of the arrester. The ends of the arrester are closed by means of members 18, 19 which include frangible diaphragms 38. The diaphragms are secured to the ends of the tubular housing 11 and are ruptured when excess gas pressures are built up in the housing. Should only moderate pressures be built up therein the diaphragm 38 will move outwardly without rupturing but will be punctured by means of a member 48, having pointed ends, carried by the end closure member 19 only whereby a slow emission of gas may take place. The interior bore of the arrester housing normally contains nitrogen.

Abstract: 1,082,270. Digital electric computers. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Sept. 24, 1965 [Sept. 25, 1964], No. 40760/65. Heading G4A. A digital electric circuit for performing a comparison operation comprises a subtraction logic unit to note the presence of borrow belonging to the column of upper rank of two members being compared, and an exclusive OR logic unit to note the equality or inequality of both operands and in which means is provided for using the preceding results to determine whether one of the operands is greater than, equal to, or less than the other operand. In operation the operands are stored one in register RM, one in register RT (Fig. 1, not shown) and a comparison instruction is decoded in register RO (Figs. 1 and 6, not shown) to open the appropriate signal paths. As soon as the operands are in the registers the subtraction unit calculates the borrows for the various columns of the numbers, however only the column of uppermost rank is taken into account. If there is a borrow in this rank a signal A6b (Fig. 8, not shown) and two other enabling signals are applied to an AND gate, the signals allowing a bi-stable circuit to be set. In the absence of A6b the bi-stable circuit remains reset. The exclusive OR operation or sum modulo 2 is carried out and stored in register RM. If the operands are equal then RM stores zero, thus enabling signals #A20 to #A26 from the register RM to be supplied to an AND gate (Fig. 9, not shown). If the operands are equal then the AND gate is enabled to allow an affirmationnegation amplifier AN or alternatively a flipflop to originate an A2a signal. If any of the #A20 to #A26 signals is absent then an #A2a signal is produced. Two flip-flops D30, D31 are used to indicate the three conditions x>Y, y=Y, z<y. Thus signal #A2a and three enabling signals (Fig. 10, not shown) are applied to the set terminal of D31 to record the inequality of the operands. If at the same time D26 (absence of carry) plus an enabling signal is applied to the set terminal of D30 then x>y. If D30 exists (x#y) then with two enabling signals in time t0 an amplifier Ai is caused to deliver a signal b00 which causes a program counter to increase by one. If D31 and #D30 exist (x<y) with two enabling signals in the following time period t1 then Ai emits another signal b00 and the counter again advances. The program counter advances can be used to cause program jumps.

Mould pouring apparatus for a continuous casting process comprises a ladle 11 to which is connected a syphon 12 which supplies molten metal to a mould 13 mounted on a platform 14 which in turn is mounted for vertical reciprocation on a carrier 15. A stationary pipe 38, sealed in relation to the platform 14, is mounted on the carrier 15 for supplying cooling water under pressure to the mould. The ladle 11 is mounted on a turntable 48 which may be lifted and rotated by hydraulic devices 46 and 47 respectively and which may also be tilted by hydraulic device 45 about the axis 44 which is approximately in line with the tip of the syphon 12. The ladle 11 has a bowl portion 73 at the rear and a trough 74 at the front with a throat opening 83 into which projects one end of the syphon tube 12. The syphon 12 is supported in a shroud unit 95, attached adjacent the opening 83, by means of a removable weir plate 99 and by ribs 94 at the front end of the shroud so that the syphon is securely located but sufficiently free to expand or distort. The syphon is constructed from a metal-ceramic material comprising powdered chromium and aluminum oxide which is cast and sintered. The end of the syphon tube locatable in the mould has a reduced neck portion with an opening 114 and attached to this end is an overflow cup 120. The combined area of the openings at 114 and 120 is greater than the effective cross-sectional area of the tube 12 so that maximum flow is obtained in order to flush out gases. The syphon is primed with the ladle in the position shown in dotted lines, Fig. 2 (not shown), and is tilted so that metal is discharged from the syphon into the waste pot 49. The ladle is then tilted backwards to reduce the priming flow to a rate suitable for casting, then swung about its vertical axis into the casting position and lowered so that the end with the cup 120 is positioned centrally in the upper part of the mould 13. The mould subsequently starts to fill and when the level of the metal is above the top of the cup 120 the starting plug is withdrawn and the casting operation commences. Reference has been directed by the Comptroller to Specifications 853,854, 903,232, 903,233 and 903,234.
