Title: Improvements in or relating to Brake BlockS and Linings and Clutch Linings.
Inventor: FROOD HERBERT
IPC: C08L61/10
Filed: 1917-09-08
Abstract: 121,301. Frood, H. Sept. 8, 1917. Energy-absorbing elements. - Friction clatch linings and brake blocks and linings are made from one or more layers of woven or unwoven organic or inorganic fibrous materials or fibres, such as shredded, ground, or disintegrated asbestos waste, kieselguhr, wool, hair, cotton, cork, or sawdust, or mixtures thereof, mixed or impregnated with resin formed by ihe condensation of formaldehyde or hexamethylenetetramine and phenol or its homologues. Fragments of metal, expanded metal, wires, or other reinforcements may be mixed with or incorporated in the material. The fibres, preferably asbestos, may be mixed with the resin in a finely powdered state, moulded under heavy pressure and melted by heat, and afterwards stoved to give the required hardness, or the material may be impregnated at atmospheric or higher or lower pressures with a varnish made by dissolving the resin in alcohol, acetone, &c., and afterwards stoved. In order that the material may subsequently be softened by heat and bent to any required shape, the stoving-temperature may be kept low. The powdered resin may be prepared by heating a mixture of formaldehyde, phenol, and a catalytic agent such as ammonium chloride or sodium sulphate or hydrate, or the resin may be formed in the body of the material by first mordanting the material with the catalytic agent and then adding the other constituents. To render the finished product non-inflammable, the powdered resin may be saponified with an alkaline solution such as sodium or potassium hydrate to which is added sodium ,silicate. To make the fireproofing body insoluble, lead nitrate, aluminium sulphate, or calcium chloride may be added to the solution or may be used to treat the impregnated material. A solution of aluminium sulphate is preferably added to the sodium hydrate solution or is applied to the impregnated material. In order to increase the heat conductivity of the material, the fibres or fibrous materials, preferably after mordanting, are treated with a concentrated solution of copper sulphate, aluminium sulphate, iron oxide, &c. Two or more layers of material may be united under pressure when in the saturated condition.

Abstract: 418,387. Loom lingoes. HARDAKER, J. T., Bowling Iron Works, Bradford, Yorkshire. May 4, 1933, No. 12979. [Class 142 (i).] In order to prevent the oscillation of jacquard healds, the lingoes, arranged in staggered fashion are made of non-circular cross-section. In the form shown in Figs. 2 and 3, the lingoes f are flat and are connected to the healds by flattened links g passing through holes g<1> in the lingoes and through loops a<2> of the healds. Oscillation of a lingoe, for example one of those marked 2 or 3 in Fig. 3, is prevented by its engagement with a neighbouring lingoe. In modifications, the lingoes have concave sides, or convex sides as shown in Fig. 5. Guide bars R, R<1> may be used to prevent oscillation of the outer lingoes. The healds and mails are preferably of metal.

Title: Improvement in surface condensers
IPC: F28B1/02
Filed: 1929-04-29
Abstract: 332,946. Triggs, W. W., (Ingersoll-Rand Co.). April 29, 1929. Surface condensers.- In a condenser having cooling tubes arranged within a casing ir successive groups in the direction of the air out let, bye-passes are pro, vided for the steam about the first group to another group, and in the lower group means are provided to ensure equal penetration of steam throughout the length of the condenser. The condenser comprises a shell A with a steam inlet B and condensate outlets C and D. Bye-passes X are provided to conduct part of the steam around the upper group of tubes E to the lower group. The interior of the shell is divided into compartments by partitions Q sealed into the sides and bottom of the shell. Air is evacuated through outlets R, each of which serves two compartments; the flow of air from each compartment can be controlled independently by throttling means, and the depth of steam penetration is thus maintained equal in all compartments. Condensate from the outer compartments flows into the inner through traps V and W. Water may be supplied to the two tube groups independently, as at K and L.

Title: Improvements in or relating to chucks
IPC: B23B31/02
Filed: 1957-04-29
Abstract: 833,048. Chucks; boring-heads. SYKES, A. E. April 29, 1957, No. 13524/57. Class 83 (3). A chuck has an open-ended hollow body 10, Fig. 1, housing a thin-walled lamella or sleeve 14 which is distorted by fluid-pressure to grip a tool or workpiece. The sleeve 14, having a flange 15, is sealed to the body 10 at 19, 20, and fluid medium is forced from a bore 21 of the body 10 through a passage 25, by a screw 23 in the bore, rotatable by hand at 24. This fluid-pressure acts between the sleeve 14 and body 10 to contract the sleeve on to a collet 18 engaging the work &c. In a modification, a sleeve 26, Fig. 2, in the bore 13 is sealed at 20, 27 to the body 10, the seal 27 being held by a disc 28 and screw 29. Pressure is exerted on the sleeve 26 by fluid expelled from one or more bores 30 and passages 31, by plungers 32 actuated by a cap 33 screwing at 35 on the body 10. In a further modification, fluid is supplied through a hollow spindle to the passage 25 from an external source. In another modification of the form of Fig. 2, the bores 30 are formed in a sleeve whose outer and inner surfaces are deformed by the fluid-pressure against the outer body and an inner collet. An additional modification has springs urging balls against plungers to facilitate positioning thereof. The pressure may be regulated, in the above embodiments, to allow slipping of the collets on excessive torque occurring, or radial plungers may be depressed by internal cams on a rotatable sleeve having graduations to indicate the slipping torque required for screw-cutting taps. The collets and sleeves may be tapered internally or externally. In another modification, a boring-tool 55, Fig. 6, held in an eccentric-bore 57 in the collet 54, has its cutting-edge 56 adjusted radially by rotation within bore 57. The adjustment is registered by a pointer 63 reading against a scale 64. The collet is held against rotation in the body 10 by a pin 60, and is closed by fluid-pressure applied by any of the above constructions. Specification 802,278 is referred to.

A lever-operated three-position switch comprises four fixed contacts spaced along a base, and a movable contact adapted in its intermediate position to bridge the two central fixed contacts to complete one circuit, and in its outer positions to bridge one central contact and one outer contact to complete either of two further circuits. As shown, the inner contacts comprise the heads 17 of T-shaped members 17a which are riveted over to secure the contacts and their terminals 14. The outer contacts 20a are carried by plates 20 in recesses 13, 13a, these plates being secured by the riveted ends 21b of lugs 21a on terminals 21. Movable contacts 22c are carried by a rocker 22 acted upon by a spring-urged plunger in an operating lever 24, the member 22 having a central depression 22d. The arms 22a, 22b of the rocker are guided by the parts 13d, 13e of the base 10, and the lever 24 is guided by an aperture 23a in a cover-plate 23.

Title: Process for the oxidation of xylenes
IPC: C07C51/275
Filed: 1952-05-28
Abstract: Toluic acid is produced by a method comprising slowly adding nitric acid of at least 30 per cent concentration to a xylene maintained at a temperature between 120 DEG  C. and the boiling point of the reaction mixture and removing water by distillation from the reaction mixture.  Phthalic acid may be obtained by raising the temperature of the reaction mixture to above 140 DEG  C. and continuing the slow addition of the nitric acid and the removal of water by distillation from the reaction mixture.  The reaction may be carried out in an inert organic medium which is liquid at the reaction temperatures. Mixtures of the isomeric xylenes may be used and the corresponding toluic acids and phthalic acids are obtained.  Mixtures of xylenes derived from coal tars or petroleum may be used as starting materials.  Suitable inert organic reaction media are, for example, diphenyl, diphenyl ethers, mineral oil, chlorinated diphenyl and benzoic acid. Specification 720,385 is referred to.
