Abstract: 259,677. Stirk, R. July 16, 1925. Planing and shaping; tools.-In a tool box for planing, shaping and like machines a single tool D is secured by a screw H in a cylindrical holder F which is rotatably mounted in a clapper B. A rod C is attached to the clapper and is actuated to oscillate it at the end of each stroke by means of a chain, rope, lever or the like N and a solenoid W which is energized in conjunction with the normal reversing gear of the machine. The clapper is moved in one direction by a spring P or by another solenoid, or the spring may be used in conjunction with a cam or other known device, or movement in both directions may be produced positively. The toolholder F carries projections J, Fig. 3, which engage with shoulders K on a plate M secured to the quadrant or carrier A, the arrangement being such that the tool is oscillated with the, clapper to produce end clearance on each stroke and may also be rotated on its axis slightly to produce side clearance. The tool is wedge-shaped in section and has two cutting-edges E for cutting in opposite directions. Specification 143,980, [Class 38 (iv), Electric supply and transmission systems &c.], is referred to.

Filed: 1917-12-07
Abstract: 119,345. British Thomson - Houston Co., (General Electric Co.). Dec. 7, 1917. Protective arrangements.-In the protection of parallel feeders by reverse power relays, in order to ensure that the effect of the potential windings of the relays shall be adequate even when the maximum drop of potential of the system occurs by reason of a short circuit, the potential windings consist of a relatively large number of turns of fine wire, and, in order to prevent the windings burning out on normal operation voltages, the potential windings are connected in circuit only when a relative reversal of current occurs in the feeders. In the arrangement shown, the current coils 14, 15 of the reverse-current relays for operating the circuit-breakers of the feeders 1, 2 are in series, respectively, with windings 29, 28 acting differentially on a core and normally maintaining open the potential circuits of the relays. With relative reversal of current in the feeders, the windings 29, 28 act together and the potential coils 18, 19 are energized, the relay in which the reversed current is flowing closing its trip circuit thereby causing the operation of the circuit breaker in the faulty feeder.

Title: Valve apparatus for controlling an oil supply to a plain bearing
Inventor: LOVE PHIL PRINCE
IPC: F16N7/38
Filed: 1958-06-09
Abstract: 877,234. Lubricating; bearings. GLACIER METAL CO. Ltd. June 8,1959 [June 9, 1958], No. 18385/58. Classes 12 (1) and 12 (3). Valve apparatus communicating with a main load-carrying region 5 of a plain bearing 2 comprises an adjustable pressure-control valve 26 which, under normal conditions, automatically limits the oil pressure in the main load-carrying region 5 to a predetermined value and which is automatically rendered inoperative when jacking oil at a higher pressure is delivered to the region 5. Under normal conditions, the region 5 is in communication with the valve 26 through passages 7, 22a, 24 and 25, the valve 26 opening when the predetermined pressure is exceeded thereby allowing oil to return through a port 11 to a reservoir 17. A pressure gauge 13 is connected to the passage 24. When required, such as on starting or stopping, a pump 15 supplies jacking oil from the reservoir 17 through passages 10, 22 and 7 to the load-carrying region 5, a non-return valve 23 being incorporated in the circuit as well as a spring-pressed shuttle valve 20 which closes the passage 22a and cuts off the communication with the valve 26. A leak passage leading from the passage 10 enables the rate of return of the valve 20 to its normal position, after the delivery of jacking oil has been shut off, to be controlled. In a modification, shown in Fig. 4, a spring-pressed relief valve 33 under normal operating conditions is arranged to open to a limited extent to permit flow of oil through a passage 32 to an outlet passage 36 leading to an oil reservoir 17. When jacking oil is supplied, the valve 33 moves to the right so as to seat on the seating 38 and thereby prevent the escape of jacking oil. Specification 877,233 is referred to.

Filed: 1927-07-13
Abstract: 293,572. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 13, 1927. Olefines. - Gaseous hydrocarbons consisting mainly of olefines are obtained by passing mixtures containing an oxide of carbon and hydrogen, preferably under pressure, at elevated temperatures over a catalyst comprising iron or cobalt, the velocity of the gas being substantially less than that required for the production of liquid hydrocarbons. A suitable velocity is 2 litres per hour for 50 cubic centimetres of catalyst. Preferably the catalyst also contains a noble metal or a difficultly reducible oxide, particularly an oxide of a metal of the 6th group. Other catalytic or inert materials may also be present. According to an example a gas mixture comprising 51 per cent of carbon monoxide, 44 per cent of hydrogen, and 5 per cent of nitrogen is passed at 370‹ C. and 50 atmospheres at the rate of 2-4 litres per hour through a high pressure furnace 15 mm. in diameter constructed of nickel-chromium allov and containing 30 cubic centimetres of a catalyst composed of iron and silver.

Title: Improved manufacture of alkali carbonate or alkali hydroxide
IPC: C01D1/26
Filed: 1932-07-01
Abstract: In obtaining alkali carbonates or hydroxides and ammonia by cyanidizing a mixture of alkali carbonate and carbonaceous material with nitrogen at a high temperature and hydrolysing the product, the necessary mixture of alkali carbonate and carbon is obtained by treating a mixture of alkali sulphate and carbon or carbonaceous material with carbon dioxide and steam at an elevated temperature, say 500-800 DEG  C.  According to a preferred modification, the mixture of alkali sulphate and carbon &c. is first heated at a temperature of 900 DEG  C. and the sulphide containing reaction product is treated with steam and carbon dioxide at 400-500 DEG  C. Hydrogen sulphide is also obtained.  The reaction mass may be employed in briquetted form and brown or bituminous coal may be employed as carbonaceous material.  If the hydrolysis with steam is carried out on the briquetted cyanidized product, alkali carbonate is produced but if the cyanidized mass is broken up and spread in thin layers on shallow pans for the steam treatment, mixtures of alkali carbonate and hydroxide are produced.  Examples in which the starting materials comprise sodium or potassium sulphate are given.

May 17, 1962 [Jan. 26, 1962], No. 18992/62. Heading B8J. [Also in Division F1] A double-acting hydraulic ram for advancing a conveyer or other machine towards a mine face is provided with alternative fluid conduits whereby at least two alternative effective piston pressure surfaces for extending the ram are provided. In the embodiment shown in Fig. 1, the cylinder 1 is provided with detachable end covers 2, 3 and contains a piston 4 having a tubular piston rod 5. The piston 4 has a central axial bore 6 lined with a guide sleeve in which a fluid pressure conduit 7, detachably screwed into a bore 8 in the end cover 3, is guided. The cover 3 accommodates control means for manually controlling the flow of fluid to the cylinder chambers through conduits 10, 12. To extend the ram, fluid under pressure is fed through the conduit 10 and the chamber 15 communicates through a bore 9 in the piston rod 5 and the conduit 7 to the return conduit 12 so that the effective pressure surface area is x<SP>1</SP>. If the available fluid pressure is increased, the fluid may be fed to both chambers 11, 15 so that the effective pressure area for extending the ram is x<SP>1</SP>-V. If the ram is to be used with considerably higher fluid pressure, a second fluid conduit 16, Fig. 3, is connected between a supply conduit 18 and a conduit 17, conduit 7 is connected to a return conduit and the bore 9 is plugged. To extend the ram pressure fluid is fed through conduit 10 to the chamber 11 and the effective piston area is x<SP>3</SP>. The effective piston area may be further reduced to the cross-sectional area of the conduit 7 by feeding fluid pressure to the chambers 11, 15 and the interior of the piston rod 5, Fig. 4 (not shown). In a further modification, Fig. 5 (not shown), the conduit 7 is removed, the bore 6 in the piston and the bore 9 in the piston rod are plugged so that the effective piston area for extending the ram is the total piston area. This area may be reduced by V by applying fluid pressure to the chamber 15. The conduits 7 may be changed for conduits of different cross-sectional areas.
