Patent GB-1375159-A (GB)
IPC: B29D35/00
Filed: 1970-12-22
Abstract: 1375159 Boots &c BRITISH UNITED SHOE MACHINERY CO Ltd 18 Oct 1971 [17 Oct 1970 22 Dec 1970] 49394/70 and 60864/70 Heading A3B [Also in Division B5] A method of shoemaking includes the step of directing heat on to the side portions of a shoe upper A during the moulding of a shoe bottom unit onto the upper. The method is particularly suitable for shoes having uppers of synthetic plastics material, the heat treatment imparting the required degree of shape retention to the uppers. Apparatus suitable for performing the method includes a mould assembly, a heated form and heating means. In a first embodiment (Fig. 1) the mould assembly 10 includes a base plate 8 on which are mounted a sole mould (not shown) and two movable side moulds 14, 16. A pair of radiant infra-red heaters 22, 24 are fixed to the side moulds 14, 16 by wing bolts 28. The upper A is mounted on a heated form 30 which is movable between a raised retracted position and a lower advanced position. The apparatus may be used in a top-closure sequence in which the side moulds 14, 16 are moved together and the mould cavity is then closed by lowering the form 30 to its advanced position or in a side-closure sequence in which the form 30 is lowered to its advanced position and the mould cavity is then closed by moving the side moulds 14, 16 together. Microswitches, e.g. 40, switch on the heaters 22, 24 when the mould is closed and a timing device switches the heaters off after a predetermined time. In a second embodiment (Fig. 3) the mould assembly 10a includes a base plate 8a on which are mounted a sole mould 12a and a pair of movable carrier members 106, 108. The side moulds 14a, 16a are fixed to the carriers 106, 108 and the heaters 22a, 24a are mounted on arms 128 which are pivoted to the carriers 106, 108. Brackets 140 fixed to the base plate 8a have pin 142 which engage slots 134 in lower portions 132 of the arms 128. Movement of the carriers 106, 108 to bring the side moulds 14a, 16a together causes the heaters 22a, 24a to swing about their pivots to move the heaters 22a, 24a from the retracted positions shown in Fig. 3 to their operative positions adjacent the upper. The heaters 22a, 24a are switched on by the sensing mechanism which senses when the mould is filled to terminate the injection of moulding material into the mould cavity. The heaters 22a, 24a are switched off by a timing device as above.

Title: Regulatable magnetic circuit
IPC: H01F29/12
Filed: 1978-08-31
Abstract: To provide a variable magnetic flux e.g. to provide a variable inductance in a regulating transformer, rectangular transformer core 1 has rotatable bobbins 3a, 3b mounted about opposite legs 2a, 2b. A flexible conductor 4 is wound with a portion about both of the bobbins and rotation of the bobbins in the same direction results in a change of the ratio of turns of conductor on the bobbins. By means of appropriate drives and electrical connections, this change in the turns can be used to result in voltage regulation by varying the amount of useful flux in the core. Particular drives for the bobbins and electrical connections for making use of the flux regulation are described. <IMAGE>

IPC: E21F17/02
Filed: 1979-01-23
Abstract: The invention is concerned with a cable handling system for the supply of (e.g.) fluid under pressure, and/or electricity, to a mobile machine. The system comprises a length of fixed conduit (8) extending alongside the path of travel of a machine to which power is to be supplied, the conduit defining an elongate channel (12), a slot (14) being provided in the conduit and which extends lengthwise thereof.

Title: Sealing flat roofs
IPC: E04D5/14
Filed: 1981-08-12
Abstract: Damp-proofing sheets 10a, 10b etc are adhered only to the central area 3 of each of the insulation panel 1. This is achieved either by pre- forming each panel with a central adhesive patch which is initially covered with a protective film or by pre-forming each panel so that its upper surface is coated with an anti- adhesion layer except in the central zone 3. With this latter type of panel, molten asphalt is applied between the panels 1 and sheets 10a etc, but adheres only to the central zone, 3. The use of spaced adhesive areas 3 enables the roof to resist thermal expansion. <IMAGE>
