Title: Improvements in or relating to fluid operable valves
IPC: F16D67/04
Filed: 1962-02-23
Abstract: 960,051. Clutch control; valves; fluidpressure disc brakes. ROSS OPERATING VALVE CO. Feb. 23, 1962 [Feb. 23, 1961], No. 7234/62. Headings F2E, F2F, F2L and F2V. A fluid-operable valve 70, Fig. 2, providing quick release of a clutch 26, 28 and application of a brake 36, comprises a body 74, Fig. 3, having an inlet port 82 and an exhaust port 100, a valve member 84 having a first area 88 responsive to pressure for urging the member towards a position in which communication between the ports is interrupted and a second and smaller area 76 for urging the member towards a position in which the ports are in communication, a chamber 106 in which the second area is disposed, and a restricted passage 102 connecting the chamber with the inlet. The valve is mounted in the wall of an annular cavity 42 which may be pressurized through a solenoid-actuated three-way valve 62, Fig. 2, to displace a combined clutch and brake plate 34 to the left to release the stationary brake plate 36 and engage the clutch consisting of interleaved plates 26, 28 between a continuously-rotated belt or gear-driven flywheel 24 and a crankshaft 18 for reciprocating a platen in a press. When the valve 62 is de-energized it connects the cavity 42 with an exhaust line 66 and pressure falls more rapidly on area 88 of valve member 84 than it does on area 76 which is vented through the restricted passage 102. The member 84 is thus lifted from its seat to provide a quick release of pressure and the clutch and brake are released and applied, respectively, by springs 58. The valve 70 is provided with an apertured guide ring 92 secured in the body by a snap ring 96 and more than one may be used.

Abstract: 1,178,165. Welding by fusion. GOTAVERKEN A.B. 15 Feb., 1967 [2 March, 1966], No. 7240/67. Heading B3R. An automatic machine for welding a tube 2 to a plate 1 comprises a frusto-conical guide 3 engageable with the end of the tube 2, a rotatable member 5 supported on the guide 3 and carrying a torch 8 and a retaining device 20 insertable within the tube 2 and serving to centre the guide 3 and prevent its rotation.

Title: Improvements in or relating to driving gearing
IPC: B41F13/00
Filed: 1925-03-18
Abstract: 256,997. Anglo-American Inventions Syndicate, Ltd., (Harris Automatic Press Co.). March 18, 1925. Rotary machines.-In combined toothed and friction gearing for rotary y printing- machines &c. a cylinder 8 is driven by frictional engagement with a driving-cylinder 5, to which is secured a gear wheel 4 gearing with a wheel 7 rotatable upon the cylinder 8. A pin 14 projecting from the cylinder 8 is engaged on opposite sides by a light spring 30 and a rod 17. The spring 30 is carried by a rod 27 adjustable in a pin 26 screwed in the gear-wheel 7 and is adjusted by a nut 29. The spring 30 is insufficiently strong to overcome the frictional grip between the cylinders 5, 8, so that if the cylinder 8 tends to run in advance of the wheel 7, the spring is compressed and the printing is not blurred. The rod 17 is held with its nut 24 in contact with a pin 15 in the wheel 7 by an adjustable strong spring 20 for preventing shocks. The friction cylinders are so constructed that at the end of one revolution they disengage, and the springs restore them to the relative positions determined by the toothed gearing.

Abstract: 1,126,475. Fibrous fabrics. B. RUDLOFF. 21 Feb., 1966 [27 Sept., 1965; 9 Nov., 1965], No. 7456/66. Headings DIN and D1R. A process for the continuous manufacture of unwoven felts comprises the introduction during the formation of the felt of continuous filiform reinforcements i.e. threads or strands. The fibrous material forming the felt is introduced into a mixing chamber after powdered resin has been. added thereto. The mixing chamber is maintained under partial vacuum to create turbulence of the fibrous material and resin, the fibrous material being drawn into the chamber by a spiked drum. The reinforcing threads are directed into the chamber through an interchangeable perforated guide, and the threads together with the fibrous material are drawn between the nip of two suction drums situated at one end of the chamber, Figs. 1 and 2 (not shown). The formed fleece is then conveyed through a polymerisation tunnel in which it is subjected to streams of hot air. The felt may then be cut to size and rolled. Additional charges, such as mineral powdered products, grains of cork, polyester or polyurethane foam or wood sawdust, may be added to the fibrous material prior to entry into the mixing chamber. Examples of reinforcing threads given are twisted or cabled cotton, flax, jute, hemp or ramie or metal wires.

Filed: 1945-03-26
Abstract: 589,528. Wrenches; screwdrivers. DUDLEY, C. C. March 26, 1945, No. 7540. [Class 61 (iii)] [Also in Group XIX] A spanner, screwdriver, &c. has prestraining mechanism by means of which prior to turning a nut &c., a predetermined stress shown on a scale is applied between the handle and a straining member secured to a driving element which predetermined stress retains an indicating member such as a spring pin in depressed position until an equivalent torque applied by the tool to the driving element overcomes the predetermined stress and allows the spring pin &c. to snap outwards. In the construction shown in Figs. 1, 2, the handle 10 is secured to the arm of the spanner head 16 and the predetermined stress is applied between the handle 10 and a. rearward extension 12 of the spanner arm by a screw 13a in a yoke 13 mounted on a spring pin 14 which is thereby frictionally retained in the set depressed position shown and springs outwardly when the equivalent torque is reached in driving the nut, whereupon the pin may be reset and the operation repeated. The stress is indicated by a pointer on the yoke coacting with a scale on the screw head. In a modification, Figs. 14, 15 and 17, comprising a tubular spanner 28 driven by a head 31 and a straining member in the form of a coaxial tube 37 secured by a pin 30 near the socket head 29, the predetermined stress is applied by a transverse taper pin 41 and spring bridge 36 coacting with shoulders 33 on tube 28 and shoulders 38a on tube 37, the inward movement of the taper pin being limited according to the stress required by an adjustable screw-set head 42 on the pin coacting with a scale 48. In the screwdriver shown in Fig. 20, the straining member is in the form of an outer tube 55 fixed at its lower end to the driving stem 51 and the predetermined stress is applied by an indicator sleeve 54 bearing through a spring 58 against an adjustable screw-set sleeve 57 and carrying keys 53 engaging straight keyways 52 in the shank 51 and helical slots 56 in the end of the tube 55.

Title: Improvements in or relating to the concentration of aliphatic acids
IPC: C07C51/48
Filed: 1932-03-17
Abstract: Aliphatic acids such as acetic acid are concentrated by adding a concentrated solution of a salt or substance having high affinity with water, to the aqueous acid, and extracting with a solvent for the acid.  Suitable salts are calcium, zinc and magnesium chlorides, and suitable solvents are ethyl acetate, ether, methylene chloride, chloroform, ethylene di-chloride, benzyl acetate, benzene and mixtures thereof, or the solvents mentioned in Specification 283,702, [Class 2 (iii), Dyes &c.]. The acid may be partially concentrated by this process as a part of a two- or multi-stage process; for instance, the acid, concentrated to 70 per cent, may be further concentrated by distillation with an entraining agent.  When the concentrated salt solution is solid at ordinary temperature, such as CaCl2.6H2O, the process may be effected at a raised temperature such as 30 DEG  C.  The quantity of the salt solution may be such that after use it has half its original concentration. The solvent may be used in liquid or vapour form; in the latter case the vapour may be passed in countercurrent to the aqueous solutions in the form of spray.  In an example 1000 gallons of 30 per cent acetic acid are mixed with 400 gallons of calcium chloride solution of the composition CaCl2,6H2O at 30 DEG  C. and passed in countercurrent with a mixture of benzene and ethyl acetate.  The extract is distilled to separate the acetic acid, and the diluted calcium chloride is reconcentrated.
