Title: Improvements in or relating to processes for the manufacture of nitric acid by catalytic combustion of ammonia
IPC: C01B21/26
Filed: 1956-11-08
Abstract: <PICT:0808234/III/1> In the production of nitric acid by the successive operations, each carried out under pressure, of catalytic oxidation of ammonia to produce water vapour and oxides of nitrogen, condensation of the water vapour, further oxidation of the oxides of nitrogen, and absorption of the resulting oxides of nitrogen in aqueous nitric acid, the water vapour is condensed by absorption in aqueous nitric acid of such strength that substantially no oxides of nitrogen are absorbed, the resulting solution being passed to the absorption operation.  The nitric acid may be of such strength that oxides of nitrogen are evolved therefrom on condensation.  Absorption may be effected in a multistage absorption system, the last stage being fed with water which is passed as nitric acid of increasing strength from one absorption stage to another, nitric acid for the condensation being recycled from an appropriate absorption stage. The condensation may be effected by spraying the nitric acid into a scrubber tower.  As shown a mixture of air and ammonia is passed under pressure through a condenser scrubber 4, an oxidizer 5, and six absorption scrubbers 6-11 connected in series at their lower ends so that nitric acid of increasing strength may pass through the system from scrubbers 11 to 6.  Acid is recirculated from the bottom to the top of each of scrubbers 6 and 8-11 via a pump 12-16 and water cooler 17-21.  Acid is recirculated from the bottom to the top of scrubber 7 via a pump 22, scrubber 4, pump 23 and water cooler 24.  The exhaust gases pass off through line 25 while the nitric acid product is obtained from line 26.

Abstract: 345,347. Key-board switches for electric totalizators. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, and HARRISON, H. H., 15, Mayville Road, Mossley Hill, both in Liverpool. Dec. 23, 1929, No. 39349. [Class 38 (v).] A key-set for use in electric totalizator systems comprises a number of sliding bars which are adapted to be displaced longitudinally by the action of a set of key levers on the oblique edges of teeth provided on the bars. A bar 1 is supported on rollers 4, 6 and has teeth 7, 11 on its upper edge. A set of key levers 8, 9 is mounted at right-angles to the bar 1 and above it. On depressing a key 8 it engages a bevelled edge of a tooth 11 to move the bar 1 to the right, and, while the key remains depressed, the bar is locked in position. An extension 16 on the bar 1 serves to operate a contact spring- set 3, 5. The bar may be returned by the pressure of the contact springs or by a key 9 engaging a tooth 7 bevelled in the opposite direction to the other teeth. In the latter case, the bar 1 would terminate at the dotted line 10 to allow for movement towards the frame 15. A set of six bars such as 1, parallel to each other and each with a contact spring-set, comprises a complete key-set, so that one key operates all six bars. The teeth on the bars may be bevelled in different directions so that the depression of a key moves some of the bars to the left and some to the right. Specification 343,034 is referred to.

Title: Hydraulic pressure producer for injection moulding machines
IPC: B29C45/82
Filed: 1953-12-11
Abstract: 763,978. Injection-moulding machines. ECKERT & ZIEGLER GES. Dec. 11, 1953 [Dec. 20, 1952], No. 34545/53. Class 87(2). The injection plunger 8 and one or both of the mould carriers 2, 3 are moved hydraulically under the control of a dual piston 15, 16 sliding in a double-acting cylinder 17 having an extension 18. The piston part 15 is larger in cross-sectional area than the piston part 16. Part 15 is a sliding fit in cylinder 17 and part 16 is a sliding fit in extension 18. When the piston is moved to the left from the position shown, pressure passes from extension 18 through line 20 into cylinder 4 and acts on piston 5 to close the mould carriers together and force carrier 2 against the injection cylinder to seat the nozzle. Simultaneously, pressure passes through line 20<SP>1</SP> to the injection cylinder 11 and moves the injection plunger sufficiently to compress the granular material in the cylinder but not sufficiently to force it out through the nozzle into the mould. When the piston part 15 reaches an enlarged part a of the cylinder 17 it no longer exerts pressure, but piston part 16 enters extension 18 and exerts a high pressure on all parts, the plunger 8 being urged leftward to fill the mould. The dual piston 15, 16 is moved by means of a pinion 12, toothed rack 13 and rod 14, the pinion being turned by hand or by an electric motor. Two pressure accumulators 23, 24, each half filled with liquid and half with gas, help to move the dual piston. Accumulator 24 may be dispensed with, its feed line 26a being connected to 23 as shown by dotted lines. A valve 27, closed during normal operation, is provided for the purpose of keeping the dual piston stationary during adjustment of the rack and pinion to allow for differing lengths of moulds. When very short moulds are used the movement of injection plunger 8 must be retarded, to prevent premature injection, and this is done by adjusting a throttle valve 28.

Abstract: 1,153,671. Conference circuits. WESTERN ELECTRIC CO. Inc. 4 Aug., 1966 [6 Aug., 1965], No. 34948/66. Headings H4K and H4R. In a system comprising a number of line circuits with transmit and receive terminals T1, R1 &c. and a common talking bus, a TDM arrangement is employed whereby the transmitters are connected during successive time slots to the bus while the corresponding receivers are disconnected from it, so that the effect of echoes is eliminated. Each transmitter is connected to the bus through a sampler, while each receiver is connected through an integrator. In a 20-line system, Fig. 1, the connections are controlled by a 20-stage ring counter operating at a 200 kc. rate so that each transmit terminal is sampled at a 10 kc. rate. Two such systems may be coupled together, Fig. 2 (not shown), during one time slot of each to provide a 38-line system. Further, a 380-line system may be obtained by employing a central 20-line system S0 Fig. 3, to couple together twenty 20-line systems such as S1, S6, S11, S16, each serving 19 line circuits. Detailed circuits are described of the ring counter and of the transmit and receive portions of the line circuits, each of which includes a semi-conductor switching device. The common bus is grounded momentarily at the end of each time slot to dissipate any residual signal after each sampling operation, and thus improve echo-suppression.
