Abstract: 1295151 Two-part couplings SOC COQFRANCE 12 Feb 1970 6755/70 Heading H2E [Also in Division H1] An electrical apparatus comprises a metal shell 1 having a block of solid dielectric 2 moulded therein. The dielectric block has embedded therein a set of bars 3 and two connecting rods 6 and 7. One end of the rod 6 is connected to one of the bars 3 and the other end projects into a cup 2a formed in the dielectric block and filled with a dielectric liquid having a level D 1 . The ends 7a and 7b of rod 7 project into similar liquid filled cups 2b and 2c. An insulating vessel 11 fits into the shell 1 and has moulded into partitions 11b thereof contacts 9 and 10 which make connection to the ends 6a and 7a of rods 6 and 7. The other ends of these contacts 9 and 10 make connection to rods 8a and 8b of a breaking device 8 which is slidable in the vessel 11 to make or break these connections. The vessel 11  is filled with insulating liquid up to level D 2 . Also fitted into the shell 1 is a rod 17 formed with a contact 18 for connection to the end 7b of the rod 7, the other end of this rod 17 being formed with a contact 19 for connection to a pin 14 rigid with the end of a cable 13 contained in a metal casing 12. The connection between the contact 19 and the pin 14 is immersed in a dielectric liquid contained in a solid dielectric cup 15. The liquid in dielectric cup 15 is introduced at 16 and has a level D 3 . An earthed wire grid 20 is embedded in the block of dielectric 2, and this block may be divided into sections. Instead of the block 2 being moulded into shell 1 it may be suspended by tie-rods (4, Fig. 2, not shown) from the cover (5) of the shell 1 or it may be separated from the shell walls by wedges or pegs (p, c, Fig. 3, not shown).

Abstract: 1314815 Centrifugal moulding JOHN ORME Ltd 24 June 1970 [24 June 1969] 31719/69 Heading B5A A rotational moulding machine for plastics material which may be in powder form includes three mould carriers 10, each rotated about axes at right angles to each other, spaced 120 degrees about a central horizontal shaft 26 driven intermittently to convey the carriers, in turn, from a mould loading and unloading station X, to a heating station Y where the moulds on their carriers are heated in an oven whilst being rotated, and finally to a cooling station Z. The oven has two separate door assemblies 150, 158, each pivotable about a horizontal axis on hinges 159, both doors being opened or closed simultaneously by being raised or lowered about their hinges, enabling the insertion and removal of the mould carriers. The door operating mechanism includes a vertical threaded shaft 108 rotated about its axis, in either direction by a motor and gearing, whereby a threaded member 124 is raised or lowered. The member 124 is connected by pivoted links 126, 128 to arms 130, 132 pivoted at their upper ends to the machine frame; the other ends of the arms carry rollers which move in guide members 144 of each door assembly. Upward movement of the member 124 swing the doors open and vice versa. Each mould carrier 10 is fixed to a hollow shaft 12 which rotates about its axis upon a support cradle 14 (16 or 18) which rotates about a horizontal axis extending through cradle stub shafts 46, 50 engaged within bearings on a framework 22 fixed to the main shaft 26. The rotation of the cradles and the carriers is effected in a manner similar to that described in Specification 1,302,381, as are means for stopping a cradle when at the loading station, and means for supplying a gaseous medium under pressure to the moulds. Nitrogen may be fed to the moulds when at the heating station, and air at the cooling station. Hot air is circulated to and from the oven by a fan having a burner in its outlet duct. Cooling at the station Z is provided by two fans 119 which blow cool air which may carry water droplets over the moulds. The machine operation is made semi-automatic by the provision of microswitches and a time delay switch controlling the sequence of movement of its various parts.

As shown in Figs. 1 and 2, glass sheet 1 drawn upwardly by rollers 5, 5<SP>1</SP> from molten glass 2 has conventional coolers 16, 16<SP>1</SP> and edge rolls 17, 17<SP>1</SP> adjacent the meniscus and, just above, the signalling components comprise electrodes 18, 18<SP>1</SP> with extremities close to the opposed faces of one or both margins, the electrodes 18, 18<SP>1</SP> forming part of a signalling system 19, 20, 21 which may give an audible or light warning 24, 25 and preferably also operates movable rollers 6<SP>1</SP> and 7<SP>1</SP> which, with fixed rollers 6 and 7, grip the buckling sheet 1. In alternative constructions, plate electrodes which may be internally cooled may replace the electrodes 18, 18<SP>1</SP> or, as in Fig. 9, the electrodes are replaced by a pair of tubes 83, 83<SP>1</SP> which discharge gas against opposed margins through tube ends 85, 85<SP>1</SP> just above the edge rolls 84, 84<SP>1</SP>. Buckling of the glass sheet 79 causes variations of the gas pressure in the tubes 83, 83<SP>1</SP> which have flow restrictors 90, 90<SP>1</SP> through which a constant gas pressure is maintained from pipe 91 and regulator 92, the inner part of tubes 83, 83<SP>1</SP> being connected by tubes 93, 93<SP>1</SP> to a measuring instrument 94 which emits a signal on variation of pressure to give audible and/or visible signals and also brings into operation the rollers 6, 6<SP>1</SP> and 7, 7<SP>1</SP> so that the broken sheet shall not foul the tube ends 85, 85<SP>1</SP>. Suitable electrical circuits are disclosed. The electrodes are preferably of refractory steel or may be of very high melting glass, or a carbide, nitride or silicide.

Abstract: 1317107 Indicators for conveyers CROWN CORK CO Ltd 4 Oct 1971 [30 March 1971] 8180/71 Heading B8A A conveyer has a signalling device which emits a signal when the conveyer has travelled a predetermined distance. As shown, tin plate 10, after being printed by rollers 12, is fed between wickets 21 of an endless conveyer 13 in a drying oven 14, the plate then being stacked at 15 by a further conveyer (not shown). A signalling device comprises a spoked wheel 23 driven by the conveyer, the wheel causing pulses to be received, via a detector 16, by a counter 17 when the latter is energized by a manually operated button 18. An alarm 19 is operated when the number of pulses transmitted to the counter 17 corresponds to the number of pulses generated during the passage of one point on the conveyer through the oven. If an operator at the input end of the oven 14 notices faultily printed plate he energizes the counter 17 and operation of the alarm coincides with the faulty plate reaching the end of the oven thus warning an operator at this end. The detector 16 may be actuated by the wickets 21 or by articles carried by the conveyer.

Title: Clamp serving to connect form panels and having clamping jaws urging together the sections at the edges of the panels
IPC: E04G17/04
Filed: 1995-01-22
Abstract: A clamp (1) serves for connecting webs (2) at the edges of form panels disposed in coplanar, side-by-side relation and has for this purpose two clamping jaws (4) urging these edge webs (2) together, each clamping jaw (4) having an 10 adjusting arm (5) which is at an angle thereto and is located at the jaw-end remote from the clamping point (4a). The adjusting arms (5) in turn have points for applying an actuating or adjusting element in the form of a wedge (9), these points of application on the two adjusting arms (5) suitably being combined to form a single point for applying the wedge (9). The wedge (9) can slide along between this point of application and the edge webs (2), suitably on the abutment (12) belonging to the clamp (1), and thereby can move the point of application and accordingly the adjusting arms (5) away form the lining skin (3) and thereby close the clamping jaws (4). For reasons of space and for proper guidance a curved wedge may be provided which is movable in the plane in which the clamping jaws (4) close.
