Title: Improvements in or relating to brick or like walls
IPC: E04B2/72

Abstract: 521,170. Nailingslabs for walls, floors and ceilings. SHARPLES, A. G., and BRYAN, H. A. Nov. 11, 1938, Nos. 32782 and 33412. [Class 20 (iv)] Relates to walls, floors, or ceilings, particularly of the kind formed of hollow blocks or tiles, and consists in the provision of a narrow wooden or like slabs arranged edgewise between the bricks &c. so as to provide a nailing surface at opposite sides of the brickwork, the slabs having projections such as flanges to engage at least one of a pair of adjacent bricks so as to key the slab against movement normal to the face of the brickwork. The blocks shown in Fig. 1 have three superposed horizontal cavities 20, 21, 22 of rectangular cross-section, and the wooden slab 24 is provided with projections 27 adapted to fit the ends of the upper and lowest cavities 20, 22 in the blocks. The projections 27 may be located on the same side of the slab as shown in the left-hand side of Fig. 1 or on opposite sides of the slab as shown in the right-hand side of Fig. 1. The keying between the projections 27 and the mouths of the cavities in the blocks may be assisted by the application of mortar. Apertures may be provided in the slab to interconnect the cavities of adjacent blocks. The width of the slabs may be such they stand proud of the brickwork on one or both sides thereof and the plaster on the brickwork faces may be arranged either to lie flush with, and to cover, the insert. In some cases, the slab need not extend for the full depth of the brick, and in this case it is provided with a single projection 27. The slab shown in Fig. 8 is of I-section, and the ends of adjacent bricks B are adapted to engage between the flanges 33 of the section. The slab may also be shaped so that the flanges 33 project only from one face of the strip so as to provide a channel-shaped member, and the slab may also have the projections 33 on the ends of the slab projecting in opposite directions, When the invention is applied to floors and ceilings, the joint between adjacent blocks is of reinforced concrete.

Abstract: 637,272. Photo-mechanical printing-surfaces. MILFORD-ASTOR, Ltd., and IMAGE, W. E. Dec. 12, 1947, No. 32782. [Class 98 (ii)] In a process for producing type, the characters are reproduced on the face of a sheet or block of brass or other metal by photographic means, the face is deeply etched so that the characters stand up in relief, and the sheet or block is cut to separate individual type pieces. The characters are drawn by hand as on paper and photographed. The resulting negative is printed on the surface of a metal block coated with light-sensitive material, the image is developed, and the surface etched ; the processes being performed in known manner except that the etching is deeper than usual. Lines may be drawn round the characters on the paper, which act as guides in the separation of the reproduced characters. A second negative may be produced from the first, and used in a similar way to produce on the rear face a set of intaglio characters.

Filed: 1970-07-07
Abstract: 1299625 Splicing tool DEFENCE SECRETARY OF STATE FOR 1 July 1971 [7 July 1970] 32784/70 Heading D1T The rope splicing tool shown in cross-section in Fig. I has a lower cylindrical end 2 and an upper tapered end 3, the end 2 being formed with a blind bore 5, to receive a rope end, and a transverse slot 9 extending through the walls of the bore 5. The tool also has the transverse passages 7 and 8. Fig. 4 shows the tool mounted upright on a stand 11 by passing the upper arm 16 of the stand through passage 8 with the lower arm 15 of the stand in slot 9. A rope 18 can then be forced onto the tool as shown in Fig. 4 and the rope pushed downwardly onto the cylindrical end 2. Thereafter the tool is removed from the stand 11 and replaced thereon as in Fig. 5 with the upper arm 16 extending through the passage 7 and the tapered end 3 of the tool pointing downwardly. The rope end 19 is inserted in the blind bore 5 and the operator then pulls the rope upwardly as at CC whilst exerting a downward thrust D on the stand 11. The rope end 19 is thus caused to pass through the rope to form an eye. Alternatively two rope ends may be joined together by this means. The process may be repeated with any one rope end to ensure a firm joint.

Abstract: 393,581. Fluid-pressure brakes. BENDIX BRAKE CO., 401, North Bendix Drive, South Bend, Indiana, U.S.A. Dec. 3, 1931, No. 33517. Convention date, Dec. 4, 1930. [Class 103 (i).] In a hydraulic master cylinder movement of the piston 38 to apply the brakes draws fluid into a chamber 48 behind it and the return movement of the piston puts the fluid under pressure and into communication with the fluid lines. The piston of the master cylinder operated by the brake pedal rod 32 comprises two parts 38, 40 of different diameter, movement of which on brake application enlarges the chamber 48 between them and produces a suction to draw reserve fluid into this space from the reserve reservoir connected to a port 30, through a chamber 64 and a passage 68 controlled by a ball check valve. When the brake is released this fluid is forced past a check valve 66 into a passage 62 and into the chamber 78 below a piston 70, which is moved against a spring 72 until a predetermined pressure is attained when a spring-controlled valve 76 opens to allow excess liquid to return to the reservoir. This fluid pressure is communicated to the pipe lines connected to port 36 by passages 62, 60 when the piston 38 has returned to its release position. Pistons 38, 40 .engage each other by projections 44, 46, and in a modified form of piston, the pistons are of the same diameter and the piston 40 is positively connected to the brake pedal rod so that it is quickly returned on brake release and thus creates a suction between the pistons between which liquid is accordingly drawn.

The liquid has a density different from that of the polyolefin and is a stable liquid at the treatment temperature and pressure.  The polyolefin may be polyethylene, polypropylene, or polybutene.  The liquid may be methanol, ethanol, propanol, isopropanol, ethylene glycol, propylene glycol, glycerine, glycol monoalkyl ethers, diglycols, diethyl ether, glycol dimethyl ether, tetrahydrofurane, dioxane, pyrane, acetone, methyl ethyl ketone, cyclopentanone, cyclohexanone, ethyl acetate, acetoacetic acid esters, propiolactone, butyrolactone, formic acid, acetic acid, propionic acid, succinic acid, maleic acid, water, or aqueous solutions of organic or inorganic acids.

Abstract: 836,826. Making cartons. JAGENBERGWERKE A.G. Nov. 7, 1956 [Nov. 11, 1955], No. 33977/56. Class 18. A jaw 8 of a press for securing the ends 3 to the tubular wall 1 of a carton has elements movable to compensate for the thickness of the longitudinal seam 2. The elements 9, 11 are on either side of a central member 10, fixed relative to the jaw 8 in the pressure applying direction, and are arranged so that movement of one relative to the member 10 in the pressure direction causes opposite movement of the other. In one embodiment the member 10 is slidable on a rod 13 and the elements 9, 11 have inclined surfaces cooperating with surfaces of the jaw. Movement of one element inwards relative to the jaw causes sideways sliding of the member 10 with outward displacement of the other element. Other possible forms of transmission of movement between the elements include a rocking lever fulcrummed on the bottom of the jaw recess, Fig. 4 (not shown), a mass of small balls in the recess behind the elements 9, 11 and member 10, or instead of balls a liquid, Fig. 5 (not shown). In these embodiments the member 10 is fixed immovably to or forms part of the jaw. The elements may be arranged on the inner press element 5 instead of on an external jaw.
