Title: Improvements in or relating to bearings
Inventor: THOMPSON JOSEPH ARTHUR
IPC: F16C32/06
Filed: 1966-11-18
Abstract: 1,203,227. Bearings. PRECISION FORGINGS Ltd. 19 Feb., 1968 [18 Nov., 1966], No. 51773/66. Heading F2A. In a bearing assembly having an externally coned member which bears with an internallyconed sleeve supported within a second member and keyed therewith so as to be non-rotatable, fluid is supplied under pressure so as to bias the sleeve in bearing engagement with the coned member so as to take up radially wear. As illustrated, the externally coned member 14 is part of a pivot-pin 13 which is fixed in a frame 10. The sleeve 17 is disposed in a recess 15 in a link member 16. The sleeve is secured against rotation relative to the link member by means of a tongue 27 engaging in a recess in a thrust pad 22 which is itself keyed to the link by dowels 28. At the end of the coned sleeve having the greater surface area there is provided a peripheral groove on both the outside and inside of the sleeve, and in each groove is located a sealing ring 30, one engaging with a cylindrical portion 19 of the pivot-pin 13, and the other with the wall 18 of the recess in the link. Oil is supplied under pressure via passage 34 and ducts 35 to a lubricant channel 33, and forces the sleeve against the thrust pad 17. Lubricant may then pass freely between the bearing surfaces of the pivot-pin and sleeve. Oil grooves 37 are spaced at 30 degree intervals around the sleeve and communicate with annular ducts 36 in the sleeve. Oil filling the space between the end of the pin and the thrust pad causes the sleeve to move outwardly and into bearing engagement with the pivot-pin. The oil pressure in the space continuously biases the sleeve outwardly and so takes up radial wear. Oil passage 38 supplies lubricant to the thrust pad.

The prefabricated inspection chamber of the Parent Specification is modified in that a member of polygonal shape is used in place of the cylindrical member forming the chamber. In the example of Fig. 1, the member 10 is square and, as in the construction of the Parent Specification has an integral floor 11 formed with a main through channel 12 and preferably at least one branch channel 13 also, sockets 18 for receiving pipe spigots being integrally formed with the member 10 and floor 11 to communicate sewer pipes with the channels. The inspection chamber is moulded from plastics materials. The floor 11 may be of a different plastics material from that constituting the member 10. Floor portions 22, which slope downwardly towards the channels, may provide a working platform reached by descending a ladder (not shown) formed in one of the corners of the member 10. The axes of the sockets 18 may be at right angles to the adjacent side of member 10, as shown, or inclined (Fig. 6, not shown). In order to maintain a right angled relationship where one or more pipes are to be brought in at an angle, e.g. 60 degrees, a member such as is shown in Fig. 5 is used, where the member 25 is part hexagonal and part rectangular. An additional socket 18 and branch channel 28 also being shown. Alternatively, a member (23, Fig. 4, not shown) of hexagonal form, or a member (29, Fig. 6, not shown) of rectangular form may be used.

Title: Process for the production of Esters of Acrylic Acid
Inventor: VOELKER THEODOR
IPC: C07C69/54
Filed: 1967-11-16
Abstract: 1,155,897. Esters of acrylic acid. LONZA Ltd. 16 Nov., 1967 [16 Nov., 1966; 11 Oct., 1967], No. 52218/67. Heading C2C. Acrylates of monohydric primary or secondary alcohols boiling above 95‹ C. are prepared by transesterifying the isopropyl or isobutyl ester of acrylic acid with the monohydric, primary or secondary alcohol in the presence of a neutrally or basically reacting catalyst and a polymerization inhibitor. Temperatures from 95‹ C. up to the boiling point of the acrylate to be produced, and pressures greater than 500 mm. Hg., are used and the isopropanol or isobutanol liberated is continuously removed by fractional distillation. In a preferred embodiment of the process, the isopropanol or isobutanol liberated is distilled off from the reaction medium as a mixture with the corresponding acrylate (alcohol content between 80% and 95%) and fractionation continued in a second stage with a more effective column. Isopropanol or isobutanol may be used as dehydrating agents since each alcohol forms with water an azeotropic mixture which boils at a lower temperature than the alcohol. Examples describe the preparation of n-propyl, n-butyl, 2-ethylhexyl, cyclohexyl, N-dimethylaminoethyl and glycolmonoethylether acrylates. The neutrally- or basically-reacting catalysts are used in quantities of from 0À1% to 2% by weight and include n-butyl orthotitanate, isopropyl titanate, isobutyl titanate, butyl polytitanate, tetraethyl zirconate, lithium hydroxide, sodium ethoxide, potassium cyclohexylate, magnesium methoxide, potassium carbonate and calcium oxide. The polymerization inhibitors include indulin, methylene blue, phenothiazine, pyrocatechol and hydroquinone.

Title: Cross-lapper
IPC: D01G25/00
Filed: 1975-12-04
Abstract: 1527230 Cross lapper drives WIRA 4 Dec 1975 [20 Dec 1974] 55276/74 Heading D1N In a cross lapper which has a storage carriage 18 and delivery carriage 15 each provided with a moving lattice the lattice drive system is arranged to provide a speed which in at least one direction of movement of the carriages is different from the theoretically correct speed which would maintain an even tension in the web being laid. The lattice drive (Fig. 4) is by means of a chain &c. 101 driven by a sprocket 102 which runs over sprockets 104 and 103 on the carriages which in turn drive the lattices. Movement of chain 101 in combination with the traverse of carriages 15 and 18 provides the correct speed of the lattices on each carriage. This speed is modified by a sprocket 109 on a lever 120 which swings in phase with the carriages traverse. The chain is maintained taught by a spring loaded sprocket 112. The carriage traverse is generated by a reversing clutch RC, (Fig. 5) which drives carriage 15 by sprocket 57 and chain 53. Carriage 15 is connected to a chain 51 around carriage 18 which if the top run of chain 51 were fixed would give the carriage 18 half the amplitude of carriage 15. However the top run of chain 51 passes over a sprocket 41 driven via gearing from clutch RC to modify the traverse length. An alternative drive has an ended chain around one end of carriage 18, one end of the chain being connected with carriage 15, the other end being spring loaded and attached to the lever 120 to modify the lattice drive, Fig. 6 (not shown). A further alternative carriage drive has two carriage drive chains independently geared from clutch RC, Fig. 7 (not shown).

Abstract: 1,212,748. Silicon carbide. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 22 Nov., 1968 [25 Nov., 1967], No. 55550/68. Heading C1A. Silicon carbide crystals are prepared by heating granular silicon carbide, which may be formed in situ, provided with a core of silicon dioxide, either pure or in the form of sand or clay, at a temperature, e.g. 2000‹ to 2600‹ C., at which the core of silicon dioxide volatilizes, the silicon carbide coheres and crystals thereof form on the inner surfaces of the cavity so produced. In order to obtain the cavities of large dimensions which have to be formed in carrying out the crystallization in an Acheson furnace for example, cores may be formed locally by depositing sand 5 during the construction from a mixture 2 of sand with carbon or products supplying carbon upon heating. During the heating, e.g. by means of a carbonrod shaped electric heater element 3, the paper moulds 4 burn or char and the sand 5 of the cores volatilizes so that the surrounding silicon carbide coheres and caving in of the cavity, which is formed by complete volatilization of the sand core, is prevented. Generally, plateshaped silicon carbide crystals are formed, but if the crystallization is carried out in the presence of a Group IIIA element, particularly lanthanum, filamentary crystals or " whiskers " may be obtained.
