Patent GB-1111441-A (GB)
Title: Joint construction
Inventor: EVANS REGINALD WARNFORD
IPC: E04C2/20
Filed: 1963-10-30
Abstract: 1,111,441. Two-part couplings. GOOLE PLASTIC HOMES Ltd. 30 Oct., 1964 [30 Oct., 1963], No. 42943/63. Heading H2E. [Also in Division E2] A joint for connecting two members 10, 11 together includes a rib 12 on one member and a groove 13 in the other member, the rib having a head portion with laterally-extending or laterally-extendable projections 20, 21 and a body portion whose cross-section tapers towards the head portion, and the groove having walls which taper inwards to mate with the tapered portion of the rib and recesses 16, 17 at the bases of the walls to receive the projections of the rib which are such as to pass through the neck formed by the inwardly tapering groove walls before engaging in the recesses, the taper on the body portion of the rib and on the groove being at a small angle to form a taper joint between the two members, the joint further including a packing 19 between the head portion of the rib and the base of the groove. In the construction shown in Fig. 1, the projections are resilient and during engagement of the rib with the groove they are pressed back against the body portion and spring out again into the recesses 16 and 17. The packing is a resilient strip attached to the base 18 of the groove and this is compressed by the head portion of the rib. The tapered portion of the rib is formed by a shell 26 of reinforced synthetic resin and a strip 22 is embedded in the shell 26 the strip providing the two projections 20, 21. The strip is made of metal or synthetic plastics material; the shell is filled with any convenient core material or is left hollow. The shell can be attached to the edge of a panel during the manufacture of the panel as can the member 11. Another construction is shown in Fig. 2. In this construction the head portion is in the form of a bead of generally circular section so that the lateral projections are rounded; the recesses in the groove are correspondingly rounded. A channel runs along the length of the head so that it can be compressed during engagement of the rib with the groove and the groove is formed with a central tapered section ridge which engages the channel. The packing is a strip provided on each side of the ridge. In a further construction, not shown, the head of the rib is an inflatable tubular member which is inflated after the rib has been inserted in the groove. The joint can be used for joining panels edgeto-edge and also for connecting the edge of one panel to the face of another in order to form a corner. The packing material instead of being resilient can be hollow and inflated by the introduction of liquid or gas. Electrical couplings can be incorporated in the joint so that when the joint is made connections are simultaneously made between electrical wiring running in the panels or other members to be joined. These electrical couplings can consist of a conically tapered socket and a conically tapered pin fitting in the socket and held by spring pressure or by projections similar to those in forming the joint.

Abstract: 1,004,316. Hinges and pivots. W. E. O'SHEI. Dec. 13, 1961 [Dec. 14, 1960], No. 43039/60. Heading E2F. [Also in Division B7] A rear view mirror 2 is adjustably supported on a stanchion 3 by a ball joint comprising a socket 9, a ball member 6 having a threaded spigot 7 which projects through an aperture 10 in the socket, and a clamping member 13 slidable but not rotatable on the spigot and adapted to be pressed against the outer surface of the socket by a nut 12 screwed on the spigot, the end of the spigot protruding beyond the nut and being received and secured in an opening 15 in the stanchion in a position which allows the nut to be released to adjust the mirror.

Title: Improvements in or relating to scribing tools
Inventor: RAYSKI LUDOMIL
IPC: B25H7/04
Filed: 1960-12-17
Abstract: 920,133. Engraving. R. R. RANSLEY, and L. RAYSKI. Nov. 24, 1961 [Dec.17, 1960], No. 43495/60. Class 100 (2). A scribing tool comprises a body member having two laterally spaced feet for resting on a surface to be scribed, and a scriber projecting downwardly from the body member at one side of the line joining the feet and adapted to engage and scribe a line on the surface as t he tool is moved over said surface, and there is provided in combination with said tool guiding means adapted to be held by an operator to move the tool, said guiding means incorporating a spring acting on the tool for urging the scriber against the surface with a pressure which is independent of the pressure exerted by the operator on the guiding means. The scriber 6, Figs. 1 and 3, is mounted eccentrically on a shaft 7, Figs. 1 and 2, rotatable in the tool body 4, so that the scriber trails behind the shaft to present the correct cutting edge to the surface. The tool is provided with feet 9, secured to a part 10 fixed to the body 4 and projecting through recesses 11 in a bar 12 pivoted at 15 to arms 13 of an end piece 14 of the guiding means 2. A compression spring 20 within a bore in a holder 21a fixed to the guiding means 2 presses a piston 25 against a lever 26 pivoted to the guiding means at 28, and the lever 26 presses downwardly against the body 4. The spring force is adjustable by a screw 24. The guiding means has a foot 31 resting on the surface S to be scribed. When a straight line is scribed by running the scriber 6 along a ruler, the tendency of the scriber to be rotated by the scriber is overcome by a member 32 having a slot 33 which can be swung into engagement with flat sides 5a of a chuck 5 supporting the scriber. To lift the scriber 6 off the surface S without lifting the guiding means 2, the operator depresses the end 38 of a lever 34 pivoted at 35 to the guiding means, the end 36 of the lever 34 being connected to the tool by a strap 37 hooked under the body 4. A magnifying glass for viewing the scriber may be attached to the guiding means 2.

Abstract: 1,174,388. Heating and cooling granular material. METALLGESELLSCHAFT A.G. 12 Sept., 1968 [21 Sept., 1967], No. 43515/68. Heading F4U. [Also in Division C5] An apparatus for heat treating granular bulk feeds, e.g. for coking coal briquettes, by direct contact with hot sand, comprises a rotary tube 1 partly closed at each end by annular baffles 13, 15 and containing a fixed conveyer screw 11 surrounded by a cylindrical shroud 6 which defines an annular chamber 8. The chamber 8 contains metal flights 12 of opposite hand to the screw 11, and the shroud comprises parallel imperforate and perforate strips 9, 10, arranged alternately. Briquettes are delivered at 2 and discharged at 3, and hot sand is delivered at 4 and passes in and out of the shroud 6 through the strips 10 as it is advanced by the flights 12 to the outlet 5 through a screen 14. The coked briquettes may be cooled in a second apparatus similar to the coking apparatus, by sand which has traversed the coker (see Fig. 3, not shown), the sand being reheated in a pneumatic conveyer (25) or in a fluidized bed for recycling to the coker. Cooled sand may be returned to the coker at (30 ... 32). In a modification Fig. 4 (not shown), coking and cooling occur in the same tube 1, the coked briquettes falling from the interior 7 of the shroud 6 into the chamber 8 at one end (35) of the apparatus and being returned by the flights 12 to the outlet 5, being initially heated but finally cooled by the sand during their return journey.
