Inventor: CULL WILLIAM
IPC: F16D3/24
Filed: 1961-12-12
Abstract: 950,009. Universal joints. BIRFIELD ENGINEERING Ltd. Dec. 10, 1962 [Dec. 12, 1961], No. 44422/61. Heading F2U. A constant velocity ratio universal joint accommodates relative axial movement between the joint shafts and comprises torque transmitting balls 10 engaging axial grooves 2, 12, of elliptical cross-section, in a hollow cylindrical outer member 1 and a ball ended inner member 5, the latter of which is centred direct or by a split spherical ball cage, in a carrier member 8 axially slidable in the outer member 1, the balls 10 being maintained in the bisector plane by guide means housed within the carrier member. In Fig. 1 the guide means consists of two conically opposed rings 15 arranged on opposite sides of the ring of balls 10 and radially slidable on rings 17 retained by circlips, such sliding movement being effected by engagement of spherical surfaces 19 on the inner member 5 in central bores 20 in the guide rings 15. In Fig. 3 (not shown) the balls are guided by a split cage positioned by an intermediate part of an axial lever having ball shaped ends engaging a socket in the inner member and a seating in a retainer ring secured to the carrier member. In Figs. 4 and 5 (not shown) a similar split ball cage is respectively positioned by a part-spherical member axially spring loaded on a flanged cylindrical control member or direct by the flanged cylindrical control member itself, the flanged member being radially slidable on a retainer ring screwed in the end of the carrier member, cage movement being effected by engagement of a fixed or spring loaded partspherical end on the inner member in a central bore of the flanged control member. The joint is sealed by a flexible boot 25 at one end and a closure ring 24 at the other. Specification 950,010 is referred to.

IPC: C08F283/01
Filed: 1963-11-11
Abstract: Synthetic resins are obtained by polymerizing a mixture containing (a) a diallylidene acetal ester of (1) a dicarboxylic acid which contains no acetylenic bond and (2) an allylidene acetal of an alcohol having at least three hydroxyl groups, the acetal having at least one free alcoholic hydroxyl group, or a mixture of the diallylidene acetal ester and diallylidene pentaerythritol, and (b) an ester containing free alcoholic hydroxyl groups and derived from the reaction of an a ,b -olefinically unsaturated dicarboxylic acid, or a functional derivative thereof, with a polyhydric alcohol.  The mixture may include (c) an allyl, benzyl, or substituted allyl or benzyl, partial ether of a polyhydric alcohol, the partial ether containing at least one free hydroxyl and/or carboxylic acid group per molecule, and/or (d) allyl alcohol.  The ester (b) may be derived from a mixture of an a ,b -unsaturated dicarboxylic acid and another polyfunctional carboxylic acid containing no acetylenic or olefinic bonds, e.g. a polycarboxylic acid, hydroxy carboxylic acid or chlorinated polycarboxylic acid.  The esters (b) may be monomeric or oligomeric esters.  The mixture may be polymerized with an acid catalyst at from 20 DEG  to 120 DEG  C.  The polymerization may be terminated when a resin having a hydroxy value between 80 and 130 is obtained and the resinous intermediate product thus formed reacted with a halosilane.  The resins of the invention are unsaturated and may be polymerized with unsaturated monomers; from 10 to 80% by weight of unsaturated monomer, based on the total weight, may be used.  Unsaturated monomers mentioned include styrene, a -chlorostyrene, a -methyl styrene, vinyl toluene, N-vinyl pyrrolidone, vinyl and allyl esters, and acrylates and methacrylates. Acrolein diallylidene acetal may be included in the polymerization mixture; bases and polymerization inhibitors also may be added.  Free radical catalysts are used for the polymerization, and polymerization accelerators may be added.  In examples, an ester made from fumaric acid, maleic anhydride, ethylene glycol and propanediol-1,2, is mixed with pentaerythritol triallyl ether and reacted with bis-(2-vinyl-1,3-dioxolane - 4 - butyl) - terephthalate, -orthophthalate, -maleate and -itaconate, in the presence of boron trifluoride tetrahydrofuran complex; the resins obtained are mixed with styrene, sodium hydroxide and hydroquinone stabilizer, and the mixtures are polymerized with methylethylketone peroxide catalyst and cobalt naphthenate accelerator.  The resins may be mixed with a silicone oil, a condensation resin of formaldehyde with urea, melamine or benzoguanamine, or a filler, e.g. asbestos, titanium dioxide, ferric oxide, calcium carbonate, kaolin, powdered quartz, ground glass or silicon carbide. Specification 941,423 is referred to.

Said pipes and/or further rigid elements (not shown) may be connected to the sheet 81 at joints 87. Suction applied (at least initially) to the drain pipes draws water from beneath the sheet to press the latter against the bottom. Netting 85, concrete blocks 83, rocks (not shown), sand or gravel 88, or layers of bitumous or asphaltic material may protect the upper surface of the sheet 81. Means to inject grouting material beneath the. sheet may be provided, to fill cracks due to the drainage. Fig. 2 shows the structure used to anchor a storage tank 40; in which case, a collar 49 of an annular sealing sheet 48, is held against a wall 42 by a sealing member 50. The tank is fixed to grouting, sand or mud filled bags 51 bonded to the sheet. Water in cavity 41 and below sheet 48 is (at least initially) pumped out via well 43. Fig. 5 shows the structure applied to a flexible barrier formed by an extension 62 of a sealing sheet 60. Lines 66 and props 68 connect the upper edge to the sheet end/or rigid elements fixed beneath it. Alternatively (Fig. 6, not shown) the upper edge may be looped back onto the sealing sheet to form an inflatable barrier. Fig. 1 shows the structure used to anchor buoyant underwater storage tanks, oil pipelines, oil process plant, offshore drilling rigs or floating vessels. In this case rigid anchoring elements 17 to which a buoyed anchoring chain 23 is attached, are provided below the sealing sheet 19, and the drainpipes 13 extend into the seabed 11 possibly through a paper filter layer 14. Water is drained from below the sheet 19 (at least initially) via a line 26 and surface outlet (not shown) by a pump 27. Subsequent water seepage below sheet 19 can be periodically blown out from drainage vessel 28 into the body of water past apertures (not shown) in valve 31, with air supplied from a compresor carried on the buoy.
