Title: Improvements in conveyors
Inventor: APPLETON WILLIAM GEORGE JAMES
IPC: B65G17/48
Filed: 1967-04-01
Abstract: 1,221,776. Endless conveyers. STEIN ATKINSON STORDY Ltd. 31 May, 1968 [1 April, 1967], No. 15017/67. Heading B8A. An endless conveyer used in the manufacture of rubber gloves comprises a pair of spaced, driven, endless chains 27 with a plurality of bars 24 extending transversely therebetween and vertically slidably mounted in guides 26 fixed to the endless chains. Each bar 24 supports a plurality of formers 25, which formers are rotatable by a drive-shaft 39 rotatably supported within each bar 24 and coupled to each former by bevel gears (30, 37), Fig. 6 (not shown). The outer end of a shaft 39 mounts a sprocket 40 in engagement with a rack 41 fixed to a guide rail 42 and is thus rotated on movement of the conveyer. An arm 43 fixed to the end of the shaft 39 mounts a roller 44 in engagement with the underside of the guide rail 42 to maintain contact between the sprocket 40 and the rack 41. The guide rail 42 further serves to determine the vertical displacement of the bars 24 in relation to the endless chains 27 for the porpose of dipping the formers 25 in preparation or treatment tanks. The bars 24 also mount at their ends arms 49 with rollers 50 in engagement with guide tracks 51 whereby the bars may be rotated to vary the inclination of the formers 53 (Fig. 3, not shown). In an alternative embodiment (not shown) the sprocket 40 may be driven by an independently driven endless chain whereby to enable the speed of rotation of the formers to be varied. In a further embodiment the bars 24 are mounted on wheels and propelled along the tracks by reciprocating pushers. A hoist is arranged at each dipping stage to lift and lower the bars 24 into and out of the treatment tanks.

Title: Catemenial tampons
IPC: A61F13/20
Filed: 1959-05-04
Abstract: A tampon is made by placing an absorbent sheet in face-to-face relationship with a permeable cover sheet, folding them to form a multi-ply pad, with the cover sheet outside, and compressing the pad into a finished cylindrical shape with the cover sheet extending over the entire cylindrical surface of the tampon.  Such a construction allows short-fibred absorbent material, such as crepe paper, to be employed without risk of disintegration.  A withdrawal cord is attached in the course of the folding in such a way as to come at one end of the finished tampon, and the opposite end surface of the tampon is preferably left uncovered by the cover sheet.

Title: Improvements relating to insert sockets for anchor bolts
IPC: E04B1/41
Filed: 1924-06-24
Abstract: 218,646. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Selah, H. A.). July 6, 1923, [Convention date]. Screw sockets.-A socket for anchoring bolts, which is embedded in concrete for securing machinery &c., comprises two semi-cylindrical complementary members provided with inter-engaging ridges and slots 17, 18, 19, Fig. 3. Annular grooves 28 on the circumference of the assembled members are provided for securing wires which hold them together before the concrete is poured around them. Discs 32, Figs. 5 and 6, are assembled within the members and are provided with radial teeth 40 which eugage in corresponding teeth on the inner faces, of flanges 15, 16 on the semi-cylindrical members. A diametrical slot 33 is provided in each disc which is partially overhung by flanges 34 leaving a space 35 into which the head of a bolt may be introduced obliquely. The flanges 15, 16 are cut away and notches 37 are formed in the complimentary members, to facilitate the introduction of a bolthead when the slot 33 is registering therewith. These notches are diametrically opposed on the two sides of the socket. After a bolt-head has been introduced the discs can be turned and held in any position while the bolt is tightened by the interengaging teeth 40 or roughened contacting surfaces, thus giving a latitude as to the desired position of the bolt. Alternatively, a washer having a radial tongue may be placed over the boltshank so that the tongue engages in the part 35 of the disc 32 and also in the cut-away portion of the socket, to positively centralize the bolt, and prevent relative rotation of the disc and socket. Holes are provided in the periphery of the socket for nailing to a framework &c. during fixing, and depressions are formed in the faces thereof to give the cement an additional hold. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification in which the socket is cast in one piece and the discs are replaced by threaded members which screw into the socket and have undercut diametrical slots at their outer ends. This subject-matter does not appear in the. Specification as accepted.

Abstract: 1425153 Rechargeable cartridge AUSTRALIAN ATOMIC ENERGY COMMISSION 22 March 1973 [24 March 1972] 15535/75 Heading F4P The Specification is a divisional from parent Specification 1,425,151 for measuring the mass flow rate of gas, by injecting a radioactive tracer gas into the gas being measured. A rechargeable cartridge, for use in injecting the radioactive gas, comprises a piston 2 shaped as shown, so as to define a fixed volume with a bore 3. The cartridge is loadable via aperture 5 in the position shown in Fig. 3A with one end of the piston 2 substantially flush with the end of the bore.

The needles, which are positioned in the grooves during the assembly of the laminated structure, may have bent end portions engaging the upper surface of the board, or may have bead-like projections engaging complementary recesses in the grooves, Figs. 4 and 5 (not shown). The grooves may advantageously be disposed at an angle to the plane of the board.  To assist in the retention of the needles in the grooves during assembly, the laminae may consist of magnetically active material.
