IPC: F16B5/00
Filed: 1960-08-15
Abstract: 956,784. Sheet metal Joints. REYNOLDS METALS CO. Aug. 15, 1960, No. 28211/60. Heading B3J. A constructional assembly comprises two panels e.g. of extruded aluminium sections each planar on one side adapted to be interlocked in end to end engagement to form a wall structure having a flat continuous surface on one side thereof. The panel 1 is interlocked by a parallel sided flange 4, inclined away from an L-shaped flange 5, 6 outwardly bent at b, engaging a complementary shaped slot in the panel 2 which also comprises strut and flange extensions 10, 11. After interlocking, the flange 5 is straightened against the strut 10 so that a hook portion 8 on the flange 6 engages the end face of the flange 11. The members may be finally riveted or spot welded together via the flanges 11, 6 or by dimpling the flange 5 and strut 10 together.

Title: Improvements in or relating to the preparation of chlorinated dinitrobenzenes
IPC: C07C205/56
Filed: 1947-10-23
Abstract: Chlorinated dinitrobenzenes of the formula <FORM:0633977/IV (b)/1> are prepared by treatment of the corresponding dinitrophenol with phosphorus oxychloride or pentachloride in the presence of a suitable tertiary base, where R is hydrogen, alkyl, nitro, acylamino, -CHO, -COOX, or -CH2CH2. COOX, where X is hydrogen or an alkyl group containing not more than 4 carbon atoms, e.g. methyl and ethyl.  The base is aliphatic, partly aromatic, or one in which the nitrogen is part of a ring, e.g. trimethylamine, pyridine, and particularly diethylaniline.  An inert diluent, e.g. benzene, may be used.  With bases other than diethylaniline, the amount used should not exceed 1.25 mols.  In examples: (1), (4) and (5), 4-chloro-3 : 5-dinitrobenzaldehyde is prepared from 4-hydroxy-3 : 5-dinitrobenzaldehyde under various conditions.  The following are prepared from the corresponding hydroxyl compound: (2) ethyl 4-chloro-3 : 5-dinitro-dihydrocinnamate; (3) 4-chloro-3 : 5-dinitro-toluene; (6) picryl chloride; (7) 4-chloro-3 : 5-dinitro-t.-butylbenzene; (8) 4-chloro-3 : 5-dinitrobenzoic acid; and (9) 4-chloro-3 : 5-dinitroacetanilide.  4-Hydroxy 3 : 5-dinitroacetanilide is prepared by the hydrogenation (palladium catalyst) of p-nitrophenol in acetic acid-acetic anhydride to give 4-hydroxyacetanilide, which is then nitrated.

[Class 80 (iv).] In motor-vehicle steering-wheels having aluminium or other soft metal or alloy hubs and, particularly, spring steel or other resilient metal spokes, damage to the spokes by heat due to casting them in the hub is avoided by securing in the hub, as by casting, soldering, or welding, a ring or ferrules of steel or other hard metal adapted to receive means such as screws or rivets for securing the spokes directly or indirectly to the hub. The spokes 5, Fig. 4, may be riveted at 10 to attachment rings 8, 9, which are secured by screws 11 passing through holes 12 into threaded ferrules 6 cast in the flange 3 of the hub 1, the ferrules being flush with the under-face of the flange and having peripheral grooves to assist their retention. In a modification, Fig. 6, a modified hub-flange 14 is cast with a peripherally grooved ring 16 to receive screws 18 passing directly through the spokes 5, which fit between shoulders 22 formed by radial recesses in the flange. The continuous ring 16 may be replaced by separate part-annular plates or cylindrical ferrules, and the screws 11 or 18 by bolts or rivets, the heads appearing on the upper face of the flange being countersunk or not.

Title: Improvements in or relating to the manufacture of wood mouldings
IPC: B27F5/02
Filed: 1951-12-05
Abstract: 691,777. Moulding wood. McGUIRK, M. Dec. 5, 1951, No. 28525/51. Class 145 (i). Wood mouldings are made by first cutting rebated flat marginal faces 19 on one face of a length of rough sawn wood W (see Fig. 3) so that the two true planed surfaces thus resulting engage guides 10 on the machine table 1, and then (Fig. 4) rebating the side faces to form surfaces 21 engaging the guides 11, by means of a rotating cutter 5, and with the wood positioned by the guides 12, 13 planing the wood to the required profile. As described and illustrated, the work is thus planed on the side faces (see Fig. 5) down to the bottom of the rebates' 21 by cutters 6, 7. A further cutter is employed to remove the rough portion of the wood between the original rebates 19. Any desired profile can be moulded, and after the rebates 19 are cut away the resultant plane surface of the wood slides over a flat pad between the side guides which holds it true during subsequent profiling operations. The method can be practised on a machine described in the specification in which case the initial rebates (19) are worked on a normal planing machine with a suitably shaped cutter and then transferred to the machine, the table of which is laid out as shown in Fig. 1. The various cutters are arranged in the gaps 2, 3, 4. Alternatively the multicutter machines may have a planing cutter arranged ahead of the guides 1 to work the initial rebates.

Title: Vehicle braking system having a proportioning valve
IPC: B60T11/34
Filed: 1973-06-18
Abstract: 1385609 Pressure intensifying valves FORD MOTOR CO Ltd 18 June 1973 [17 July 1972] 28812/73 Heading F2F In a dual brake system, the front wheel brakes communicate with the fluid supply via a proportioning valve including an intensifier operable only above a predetermined pressure value so that above this value, the brake pressure rises at a faster rate than the increasing supply pressure, a metering valve prohibiting communication to the front brakes when the supply pressure is below a value lower than the predetermined pressure value. A tandem master cylinder A supplies hydraulic fluid via a line 14, a valve assembly V, and outlets 30, 32 to individual front wheel brakes 13, and fluid via a line 18, the assembly V, and an outlet 24 to rear wheel brakes C. Both supplies act upon opposing end faces of a pressure balancing piston 50, combined with a failure indicator plunger 57a. The front brake supply also passes through an orifice between a ring 86, fixed on a differential piston 63, a piston flange 64 and a resilient element 62, the piston being spring urged to the left, and the element abutting a shoulder in the assembly housing. An annular convoluted spring 84 retains a gap between the element 62 and the flange 64. The fluid passes the flange 64 to the outlets 30, 32. Upon supply pressure increase, the piston moves rightwardly until a predetermined supply pressure value causes engagement of the ring 86 with a ring 42 fixed with the element 62 to block fluid flow. The piston 63 provides different areas exposed to supply and brake fluid causing pressure intensification of the brake fluid with respect to the supply pressure since the supply pressure area is that of the ring 86, and the brake pressure area is that of an annulus surrounding an extension 63b of the piston. The shoulder may be replaced by a stepped ring 117, Fig. 11, which also defines, with a stepped end of the piston 211 and the element 116, the orifice, the element having passages 116b therethrough. Here, the piston flange 124 is a separate component to the piston. To provide further front brake pressure control, the metering valve is inserted in the lines downstream of the valve assembly V, whereby fluid is not supplied to these brakes until a predetermined pressure level is achieved, the brake pressure being supplied in greater degrees of full assembly outlet pressure until the predetermined intensifying pressure value for the valve assembly is attained.
