Abstract: 1,136,773. Disc brakes; hydraulic brakes. GIRLING Ltd. 6 April, 1966 [13 April, 1965], No. 15591/65. Headings F2E and F2F. A disc brake comprises a stationary member 10 located on one side of a disc 13 and secured to a fixed member adjacent the disc, an hydraulic actuator 17 slidably guided for axial movement to and from the disc in said stationary member and spaced parallel arms 14 extending forwardly towards the disc from radially and outwardly extending lugs on said stationary member, said arms providing inner guide surfaces 22 for a first friction pad assembly (19), Fig. 2 (not shown), which is applied to one side of the disc by a piston (18) working in said cylinder, and outer guide surfaces 25 for a yoke 28, which straddles said member and a portion of the disc periphery and is axially moved by the cylinder to apply a second friction pad assembly (30) against the other side of the disc. The outer guide surfaces on the arms are constituted by grooves in which yoke sides 26 slide, plate springs 29 being interposed the bases of the grooves and the yoke to prevent rattle therebetween. The inner guide surfaces are partcircular and guide the complementary partcircular end edges of a backing plate (20), Fig. 2, associated with the pad assembly (19). On removal of locking pins (not shown) adjacent the side edges of the pads or of a mounting bolt (not shown) securing the stationary member, the pad assembly (19) may be rotated through 90 degrees and removed radially. The hydraulic cylinder is axially guided on part-circular surfaces 15, 15, 16 on the stationary member. In a modified embodiment, Fig. 3 (not shown), the cylinder 52 is slidably guided on extending projections (53) formed on the walls of a bore in an axial extension of the stationary member.

IPC: C03C8/00
Filed: 1937-06-07
Abstract: A process for producing a protective colloidal film, resistant to acids and alkalies, on the surface of an aluminium or aluminium alloy article, consists in preliminarily heating the article to about 100 DEG  C., treating the article with an alkali-silicate solution at a temperature of about 50-70 DEG  C., thereafter treating the article whilst still warm with a precipitating solution at a temperature of about 30-40 DEG  C., and finally heat-treating the article at 100-300 DEG  C. to render the film irreversible and firmly adherent. Specified precipitating solutions are those of ammonium chloride, ammonium hydroxide, and alkali carbonates, bicarbonates, sulphates, bisulphites and chlorides.  A wetting agent, e.g. soap, may be added to the alkalisilicate solution, and both solutions may be applied by a dipping, spraying, brushing or similar operation.

Title: Improvements in or relating to epoxy resins
Inventor: HOWE BRIAN RUSSELL
IPC: C08G59/08
Filed: 1954-06-09
Abstract: Epoxy resins are prepared by modifying a novolak resin with an unsaturated aliphatic or cycloaliphatic hydrocarbon and then etherifying the modified resin by means of a haloepoxyalkane. Unsaturated hydrocarbons specified are propene, isobutene, cyclopentadiene, methylcyclopentadiene or their low polymers; haloepoxyalkanes are epichlorhydrin or epibromhydrin; the reaction is carried out in presence of alkali added in portions. In Example (1), 3000 parts phenol are mixed with 1800 parts 40 per cent formaldehyde and 18 parts oxalic acid.  The mixture is refluxed and distilled under vacuum; 150 parts of the novolak resin thus produced are mixed with 150 parts triisobutene and reacted at 85 DEG  C., in presence of 2 parts boron trifluoride/acetic acid complex.  The modified resin thus obtained is dissolved in 465 parts epichlorhydrin, 2.6 parts water and 6 parts sodium hydroxide pellets are added and the temperature adjusted to 80 DEG  C.; four similar additions are made at intervals of 20 minutes; the product is refluxed, vacuum distilled, dissolved in xylol and filtered to remove salts.  An epoxy resin soluble in hydrocarbons and ketones is obtained.  British Specification 615,488, Belgian Specification 503,549 and German Specifications 668,952 and 673,828 are referred to.
Patent GB-665221-A (GB)
Title: Improvements in or relating to the bodying of fatty oil acid esters
Filed: 1949-06-20
Abstract: Unsaturated fatty oil acid esters are bodied by heating a polyhydric alcohol ester of one or more non-conjugated drying or semi-drying oil acids at a bodying temperature in the presence of a cyclic diketone, such as a quinone, and in the presence of sulphur dioxide.  The esters so bodied to the point of incipient gelation may then be superbodied by heating them at bodying temperature in the presence of steam.  Natural and synthetic drying and semi-drying oils are treated, soya bean oil, pentaerythritol ester of soya bean oil fatty acids, and linseed oil being specified; the esters have an iodine value of more than 120.  The bodying temperature preferably ranges from 500 DEG F. to 625 DEG F.  The cyclic diketones specified comprise anthraquinone, b -carboxyanthraquinone, retene quinone, and b -chloroanthraquinone.  The sulphur dioxide is preferably blown into the hot ester in the form of an admixture with an inert gas such as carbon dioxide or nitrogen.  The quinone may be added before or during the stage of heating the ester to bodying temperature.  The heating is preferably stopped and further bodying prevented when the ester has reached a cure point of not less than 5 seconds.  This is effected by cooling the hot ester by the addition of rosin or fatty acids, such as linseed fatty acids, or a mixture thereof or by the introduction of water or steam into the hot ester.  During the heating of the ester, already containing the quinone, carbon dioxide is blown into the hot ester and after reaching the bodying temperature the sulphur dioxide is admixed with the inert gas.  The process enables the rate of bodying to be greatly increased and also to use lower bodying temperatures than usual.  If the bodied esters are then to be superbodied, the polymerization is checked by blowing with steam and the bodied esters again held at the bodying temperature while passing steam therethrough.  Alternatively, the steam may be generated in situ by introducing water into the hot esters. Further bodying is checked at a similar point and by similar methods as above described.

Filed: 1924-07-09
Abstract: 234,766. Calorizing Co., (Assignees of Mantle, G. D.). May 28, 1924, [Convention date]. Regenerators.-In regenerator apparatus of the kind described in Specification 221,188 in which the air or gas to be heated is passed first over the hottest portions of metal heating-tubes, then over the coldest portions, and finally over portions at intermediate temperatures, the air or gas is passed through the highest temperature region at a high velocity. The apparatus shown comprises a casing 2 with end header-plates 3, 7 for tubes 5, through which the heating-gases flow upwards. An intermediate tube plate 4 is spaced a short distance from the lower plate 7, and the air or gas to be heated, after passing from the inlet 13 through the casing 8, surrounding the lower end of the main casing, flows at a high velocity through the restricted space between the plates 4, 7. The air then passes upwards through the conduit 17, and finally downwards along a zig-zag course around the tubes 5 to the exit 21. The baffle plates 22 are suspended from the upper header-plate on rods 23, and are separated by tubular spacers 24. Expansion of the tubes 5 is allowed for by connecting the upper header-plate to the main shell by a flexible 'expansion fitting consisting of annular plates 26 and spacer rings 27.
