Patent GB-1375373-A (GB)
IPC: B29D99/00
Filed: 1971-11-08
Abstract: 1375373 Continuous production of gaskets INSIT SpA 8 Nov 1971 [11 Nov 1970] 51826/71 Heading B5A Gaskets are continuously produced by forming a continuous strip of composite material from raw materials, e.g. by calendering or extrusion and calendering, this strip being slightly thicker than the finished gaskets, punching blanks from the strip, vulcanizing the blanks under pressure, and trimming the vulcanized blanks to form the finished gaskets. The blanks may be of a size to form one gasket or several. The raw materials including cork and a vulcanizable elastomer are preferably fed from silos 1 through outlets 2 on to a conveyer 4 which feeds them to a mixer 5. Rubber slabs may be dispersed from a balance 3. The mix then passes to a roll mixer 6 which passes a sheet to a strip conveyer 7 and through calenders 8 with a tensioning roller 9 where the sheet is converted to strip of the desired thickness, i.e. about 5 to 10% greater than the finished gasket. An additional layer for strengthening, protection or adhesion may, if desired, be applied to at least one surface of the strip or may be sandwiched between two strips. The strip then passes over cooling rollers 10, past a checking and stamping device 11 to a punch 12 which produces either multiple blanks (Fig. 5, not shown) or single blanks (Fig. 6, not shown) the dimensions of which are such that a margin of material remains to be trimmed after vulcanization. Offcut material is recycled via mixers and conveyers 13 to 17. Vulcanization may be effected in various ways, e.g. by passing the blanks through heated steel belts 18 and then postcuring at lower temperature in a hot-air tunnel 19; or by loading in stacks on to trolleys and curing slowly in the hot air tunnel (Fig. 2, not shown); or by hot-pressing and then stacking on trolleys for post-curing by hot air (Fig. 3, not shown); or by passing the blanks over a heated drum against which they are pressed by a steel belt (Fig. 4, not shown) and then post-curing. The finished gaskets are trimmed to size by a punch 23, the off-cuts being comminuted by a milling machine 25 and returned to the silos. Instead of the two-stage calender shown, an extrusion machine may initially form the strip which may then be sized either by separate rollers or by calenders associated with the extruder.

Title: Indicating devices
IPC: G01R1/08
Filed: 1970-11-05
Abstract: 1334536 Indicating device AGFA-GEVAERT A G 5 Nov 1970 [5 Nov 1969] 52685/70 Addition to 1329258 Heading G1J A modification of the indicating device of the parent Specification 1329258 comprises a plurality of rotatable pointers 5, 6 having parallel spaced axes of rotation, a scale 9 and a reflecting surface 2. The free end 7 of each pointer is parallel to the axes of rotation and is viewed by reflection in the surface 2 of prism 1 along with a corresponding portion of scale 9 so that each pointer end portion 7 appears to move laterally. A separate scale 10, 11 may be provided for each pointer or a single scale may cooperate with several pointers and the scale may be in front of or behind the pointer ends. The pointers may be hidden at the ends of their travel by opaque areas on the prism 3 or scale 9 so that if each pointer starts to move as the previous one reaches the end of its travel the observer appears to see a single pointer travelling along the scale. In Figs.1, 2 control device 28 is actuated when lever 25 is depressed and is arranged to switch moving coil unit 3 off and  moving coil unit 4 on when image 30 of pointer end 7 reaches the end of its travel. Alternatively a pointer may be arranged to actuate a switch when it reaches the end of its travel to actuate the next pointer. As a further alternative the  pointers may be set manually by a transmission arranged to operate each in turn as the previous one reaches the limit of its travel. Slides 16 may be arranged to be manually movable to a position between illumination device 17 and reflecting surface 2, Fig.1, or between the pointer ends 7 and the reflecting surface or the scale, Fig. 4. At least parts of the scale may also be manually movable by a setting device. The slides and the scale may be coloured and different colours may be used to identify different portions of the scale. Alternatively the slides may be opaque. In Fig. 1, operation of lever 25 not only actuates device 28 but inserts coloured slide 16 into position. In the embodiment of Fig. 4, actuation of the lever removes an opaque slide from a position in which it obscures the pointers. The face of the prism 3 adjacent the pointer ends may be curved e. g. cylindrical and may have the scale thereon. In a modification, the prism 1 is bevelled at the intersection of faces 2 and 8 and provided with a scale visible through the bevelled surface. The scale 9 may then be omitted.

Title: Improvements in Injection Moulding Machines
Inventor: FISCHBACH ALFRED
IPC: B29C45/70
Filed: 1966-11-30
Abstract: 1,164,864. Injection moulding machines. A. FISCHBACH. 30 Nov., 1966 [7 Jan., 1966], No. 53607/66. Heading B5A. An injection mould carrier plate 2 is displaceable by means of a variable output hydraulic pump 8 which is controlled to vary the output in dependence upon the position of the carrier plate relative to a datum position. Pump output is varied by swinging a lever 14 connected by a rod 16 to a cam roller 17 adapted to engage one cam track (18) during closing and another track (19) during opening of the mould. Cam tracks (18, 19) are mounted on a carrier 20. In one embodiment (Fig. 1) the mould carrier plate 2 is moved to the right by a piston 4, engages a plate 3 and then moves a cylinder 5 over an injection plunger 6, a cam 22 engaging a switch 24 in this right-hand position. The switch 24 actuates an electromagnet 31 to raise the rod 16, whereby the pump 8 is set at neutral by lever 14. Prior to this, a piston 26 with a cam 27 thereon is moved leftwardly by pressure build-up within the chamber 12. On raising the rod 16, a switch 30 is engaged by the cam 27, urged rightwardly by a spring 28, and the switch 30 energizes an electromagnet (32), Fig. 2 (not shown). This moves a roller 17 rightwardly above cam track (19), the switch 30 simultaneously breaking the circuit of electromagnets 34, 31, the former thereof reversing the pump 8 via a valve 11 while the rod 16 descends until roller 17 rests on track (19) and plate 2 retracts leftwardly. The configuration of the track 19 ensures a slow initial opening. Switch 25 then actuates electromagnet (33) to draw the roller 17 on to a track 18 and reverse the valve 11 via electromagnet 34. In a modification, Figs. 3, 4 (not shown), mould plates 2, 3 are locked together and the plunger 6 is operated by a separate hydraulic drive, a pump (42) being controlled by a pressure switch (44) and timer (41) to operate the plunger 6.
