Title: Improvements in or relating to hydraulic and like control valves
IPC: E21D23/00
Filed: 1957-11-08
Abstract: 908,830. Valves. CARRODUS, F. Feb. 9, 1959 [Nov. 8, 1957], No. 34854/57. Class 135. A multi-way valve assembly comprises individual valves and a common operating mechanism for selectively operating the valves. The valves are arranged in a block 10, Fig. 2, at particular angular and radial distances from the axis of a centre shaft 11 on which a plate 13 and an operating lever 15 are mounted. The operating lever 15 co-operates with a gate member 14 and the plate 13 carries tappets each of which are disposed opposite corresponding valves. The lever 15 is rotated to a particular gate slot and then rocked to move the plate 13 axially and so actuate the selected valves. In another embodiment, Fig. 6, the operating lever 44 is rotatable through 360 degrees and the gate 47 is of cylindrical form. Instead of the plate having tappets complementary to the valves to be operated it may have holes complementary to the valves not to be operated. It is suggested that the plate may operate electric switches connected to solenoid controlled actuating means for the valves. It is also suggested that the plate may be moved axially hydraulically or electrically by arranging that the lever on movement into any of the gate slots operates a pilot valve or switch.

Patent GB-814706-A (GB)
Title: Low temperature carbonylation
IPC: C07C27/22
Filed: 1957-11-12
Abstract: In the carbonylation of an olefinic compound by reaction with hydrogen and carbon monoxide in the presence of a cobalt-containing carbonylation catalyst at an elevated pressure and a temperature in the range 30-120 DEG  C. to produce oxygenated compounds having one more carbon atom than the starting olefin, at least one of the reactants (including the catalyst) is pre-treated to reduce the total water content of the reactants to below 1 per cent by weight based on the olefinic compound.  Suitable olefinic starting materials are straight and branched-chain olefines, unsaturated alcohols, e.g. allyl alcohol, unsaturated fatty acids, e.g. oleic acid, and diolefines.  Preferably the H2/CO ratio used is between 0.5 : 1 and 5 : 1.  Suitable catalysts are Raney nickel, cobalt carbonyls, cobalt oleate, naphthenate and stearate and the cobalt salts of other high fatty acids. Pressures of from 1000 to 10,000 p.s.i. may be used. The olefine feed may be dried by severe distillation or by passing the feed over a solid drying agent such as CaSO4, BaO, alumina, bauxite, CaCl2, CaO, hydrides and P2O3 or by refrigeration techniques.  The catalyst and synthesis gas may be dried by contacting with various drying agents, e.g. CaSO4, CaCl2, alumina or BaO.  In an example the process is applied to the carbonylation of n-heptene-1.  Specification 663,240 is referred to.
Patent GB-353473-A (GB)
Abstract: 353,473. Coke ovens. KOPPERS CO., Koppers Building, Pittsburg, U.S.A.- (Assignees of Becker, J. ; Koppers Building, Pittsburg, U.S.A.) April 24, 1930, No. 12689. Convention date, Jan. 28. [Classes 51 (i) and 51 (ii).] Gaseous-fuel fittings; draught, regulaling.-In a coke oven the supplies of fuel gas and air are periodically varied between maximum and minimum rates of supply. Preferably in each half heating cycle the gas and air are supplied for one-half of the period at a rate above the average rate for the desired coking time, and for the other half at a correspondingly lower rate. By,operating in this manner a more uniform heating of the charge is obtained, more particularly when the coking time is relatively long, and the rate of combustion is correspondingly low. An apparatus for automatically varying the supplies of fuel and air comprises a clock mechanism 7 arranged to control a switch 10 in the circuit of an electromagnet 4 connected to the operating-arm 3 of a valve 2 in the gas main. The arm 3 is weighted to hold the valve normally in a partly closed position corresponding with minimum rate of supply, and when the electromagnet is energized the valve is opened to the full extent. The switch 10 also controls in a similar manner, a draught regulating valve in the exhaust main, and accordingly varies the suction draught at the air inlets.

Abstract: 1,159,280. Metal oxide microspheres. W. R. GRACE & CO. 1 Aug., 1967 [2 Aug., 1966], No. 35349/67. Heading C1A. [Also in Division G61 Metal oxide microspheres are prepared by dispersing an aqueous feed containing dissolved salts of uranium, thorium, plutonium, zirconium, beryllium, yttrium or a lanthanide or a mixture of such salts in a dehydrating solvent containing ammonia at a pH of 8-13À5. The feed may also contain up to 499 g/l of suspended oxide particles of size less than 1 micron and may contain a compound which releases ammonia at the temperature of the dehydrating solvent. The solvent, which is preferably a C 4 -C 10 alcohol, must have a limited solubility for water which may be achieved by adding water prior to the spheroidizing process. The solubility of water in the dehydrating solvent, excluding water if present, should be less than 30 weight per cent. Preferred solvents are hexanol containing 2-6 wt. per cent. of water, butanol containing 26 wt. per cent water, ethyl hexanol and ethyl butanol. The dispersion may be prepared by introducing the solution through a hypodermic needle into a counter-current of dehydrating solvent as described in Specification 1,158,742. The spheres, which should contain less than 50% water are treated with concentrated ammonia to ensure complete conversion and are then washed and dried over the range 40-110‹ C. before being sintered. Metal carbide microspheres may be prepared by incorporating up to 5 moles of suspended carbon per mole of metal into the aqueous feed.

Title: Tuning mechanism for dictating machine
Filed: 1957-11-14
Abstract: 828,031. Magnetic record apparatus. COMPTOMETER CORPORATION. Nov. 14, 1957 [Nov. 19, 1956], No. 35494/57. Class 40 (2). A dictating-machine comprises an endless band of magnetic material D (Fig. 4) supported on two rollers, one of which is shown at C, a transducer A attached to an arm 24 mounted on a carriage 22 and supported for sliding movement on a rod B along which it is driven by engagement of the lower part of the carriage with a feed-screw F, thereby making a helical record trace. An adjustment screw 29 is provided for moving the arm 24 relative to carriage 22 in order to bring the gap of the transducer to the optimum position relative to the roller C, Screws 26 lock the arm and carriage together after adjustment. Provision is also made for moving the transducer transversely of the direction of the record travel and this is achieved by moving the transducer carriage and feedscrew bodily. The screw F (Fig. 6) has sliding engagement in its bearings 44 and 45 and one end 48 projects through the frame. At the opposite end a compression spring 46 acts on a collar 47 fixed to the screw and keeps the end 48 in contact with a cam 64. This cam is part of an assembly (Fig. 8) comprising a disc 61 which has a portion 64 outside the plane of the remainder of the disc. A finger lever 69 is mounted together with two washers 75 and 75a on a screw 73 passing through the end plate 72 of the machine and a further screw 76 clamps together the lever 69 and the plate 61. The lever 69 protrudes through a slot in the casing of the machine and has limited angular movement, the amount permitted being sufficient to move the feed-screw F axially a distance equal to the pitch of the record trace. The angle subtended by the cam sector 64 is at least twice the permitted angular movement of the lever 69 so that by reason of the slot 68 initial angular adjustment of the cam 64 and the lever 69 can be made in order to bring the start of the record trace to the edge of the record sheet. The starting position of the carriage 22 on the feedscrew is fixed by the collar 49. The carriage driving means comprises a hub 39 (Fig. 6) sliding on a guide-rod B and which has mounted on it an arm 41 (Fig. 4) which has side plates 42 and also a clip 43 which together with the arm 41 fit closely on the screw F but do not engage the threads. Integral with the body 23 of the carriage 22 is an arm 51 having secured to it a leaf-spring 52 with a latch 53 which engages either the front or rear side of the arm 41 and enables the head to be set in a transducing or a non-transducing position. A third arm 54 mounted on the hub 39 by means of side plates 50 carries a plate-like element 56 the edge of which engages the feed-screw F when the head is in a transducing position. A spring 55 interconnects the lower ends of the arms 54 and 41. Specifications 764,352 and 791,785 are referred to.

Patent GB-922912-A (GB)
Title: Automatic control means for crushers
IPC: B02C2/04
Filed: 1961-10-03
Abstract: 922,912. Automatic control. ALLISCHALMERS MANUFACTURING CO. Oct. 3, 1961 [Oct. 11, 1960], No. 35661/61. Class 38 (4). Deviations in the ratio of power input to material output of a crusher are automatically corrected (a) by variation of the rate of feed of material to the crusher, and (b) by variation of the size to which the material is crushed, when the volume of material in the crusher exceeds a predetermined value. In Fig. 2, the shaft 12 of a crusher is driven by an electric motor 13. Material to be crushed is supplied by a conveyer 16 and the crushed material is removed by a conveyer 18. A strain gauge 20 associated with conveyer 18 produces an electrical signal dependent on the output of the crusher which is indicated by a meter 21. The power input to the crusher is indicated by a wattmeter 29 associated with motor 13. An instrument 30 responsive to both the above measurements indicates the ratio of power input to material output. Under automatic control, when the power/output ratio falls below a desired range of values, instrument 30 applies a signal to a transistor or magnetic amplifier type control circuit 43, 44 so that if the fall persists beyond a predetermined time a motor-operated potentiometer 45 is operated to increase the speed of conveyer 16 in steps until the desired ratio is restored. Should the volume of material in the crusher exceed a predetermined value under these conditions a further circuit 50 is influenced to render circuit 43 ineffective to increase rate of feed and render circuits 48, 52, which are similar to circuits 43, 44, effective instead to operate a motor-operated potentiometer 36 associated with an electro-hydraulic system 59, 14, to raise crusher head 15 and decrease the size of the crushed material by reducing the size of the crushed material which is indicated by an instrument 34. If the power/output ratio should rise above the predetermined range of values, instrument 30 applies a signal to circuits 61, 66 which function in a similar manner to circuits 43, 48 but cause first, decreases in the rate of feed by conveyer 16 and then, if the output from the crusher falls below a predetermined value instrument 21 influences circuits 61, 66 so that the ratio is corrected by increases in the size of the crushed material instead of decreases in the rate of feed. If the hopper above the crusher should fill, a circuit 63 is influenced to cause a periodic decrease in the rate of feed, and if it overfills a circuit 72 is influenced to stop the feed entirely. If, for any reason, the power supply falls unduly, instrument 29 disables the control of feed and operates a warning light 81. A circuit 83 periodically controls circuit 43 to increase the rate of feed so that the crusher is kept working near the upper limit of its working range.

A helical seam pipe mill of the type in which, during operation, the angle between the direction of food of the strip and the line established by the centre of curvature of the concave surface of the forming tool, as well as the angle between this line and the longitudinal axis of the welded pipe, is variable, is characterized in that the guide means for the welded pipe is or are fixedly mounted and the feed device as well as the forming tool are pivotably mounted. Strip 2 from a reel 1 is fed by means 3, 4 to a forming tool 5 which coils the strip helically to form a pipe 12, the seam of which is welded, supported on means 8. The feed device 4 is connected to a turntable 6 carrying the tool 5 by adjusting mechanism A. To vary the angle that the strip being fed makes with the axis of the tool 5 means B are actuated to swing the feed device 4 about an axis 11, at the same time the adjusting means A are operated so that tool 5 causes the axis of the pipe 12 to maintain its direction. To adjust the welding gap only the means B is actuated, the feed device 4 and tool 5 then both pivoting together in the same direction. The means A may be replaced by a pinion engaging a toothed segment on the turntable 6. Alternatively the turntable 6 may be adjustable independently of the feed device 4.

Title: Composition rods igniting by friction
IPC: C06F5/00
Filed: 1932-12-19
Abstract: 401,905. Matches. OLSSON, K. E., 19, Norrbackagatan, Stockholm. Dec. 19, 1932, No. 35983. Convention date, Dec. 21, 1931. [Class 50.] Repeatedly ignitable composition rods comprise a combustible mass of organic substances which leave no ash on burning and an igniting mass segregated therefrom and containing an oxygen developing substance such as potassium chlorate with a binder having so low an affinity for oxygen and present in such proportion that the igniting mass is not combustible or at least cannot burn more quickly than the combustible body material. Aldehydes such as metaldehyde and amines such as hexamethylene tetramine may be used for the body material with a binder of nitrocellulose dissolved in acetone, and oxygen developing substances such as ammonium perchlorate, or volatile substances such as benzene or alcohol may be included to increase the speed of combustion. A more readily inflammable substance may be employed next to the igniting mass which may consist of up to 70 per cent of potassium chlorate or of ammonium perchlorate with a binder of alkali silicate such as water glass, cement or gypsum. Artificial resins such as the compound known under the registered trade mark " Bakelite," or cellulose derivatives such as cellulose acetate may be used as binders when a flame is required to ignite the body material as distinct from an igniting spark. Powdered glass or other friction substances may be included. The igniting mass may be in the form of a string within the rod or pressed in an external groove or may be applied as a cover all round or over parts of the surface of the body material. Ordinary phosphoruscontaining striking surfaces comprising, e.g. amorphous phosphorus, antimony sulphide, ground glass and gum arabic, may be employed for the ignition of the rods. The Specification, as open to inspection under Sect. 91 describes also the inclusion of sulphur in the igniting mass. This subject-matter does not appear in the Specification as accepted.
