Patent GB-896175-A (GB)
Title: Blank feeding mechanism
Inventor: JR WALTER ROBERT STELLING
IPC: B65H5/22
Filed: 1960-09-17
Abstract: 896,175. Feeding sheets. FAUSTEL Inc. Sept. 17, 1960, No. 32062/60. Class 100(1) Carton blanks B in a hopper C are fed sequentially past a gate 12 by a suction belt 13 and between feed rolls which feed each blank into a press 100 where a metal tear-strip is applied to the leading edge of the blank, and the feed rolls and the belt 13 withdraw the blank to the infeed side of the feed rolls, and deposit the blank on a delivery belt 42 which is travelling at a slower rate than the suction belt. The blanks thus drop in overlapping relationship on the belt 42, but are dropped one at a time into a container 51 (not shown) due to the presence of a retarder roll 48 resting freely on the belt.. Each blank is fed into the press 100 by segmental rolls 85, secured to sleeves freely mounted on a shaft 77, and rolls secured to sleeves freely mounted on a shaft 55; and each blank is withdrawn by segmental rolls 83 secured directly to shaft 77 and rolls secured directly to shaft 55. The infeed rolls and outfeed rolls are driven in opposite directions, and the shaft 77 is eccentrically mounted for adjustment. The outfeed is assisted by segmental flanges secured on the sleeves surrounding the shaft 77. A suction box 94, connected to a suction pump, is positioned between the upper and lower flights of the perforated suction belt 13, and it assists withdrawal of blanks from the outfeed rolls. A feed frame 4 adjustably supports the assembly comprising the suction belt 13, box 94, and blank hopper C about a pivot shaft 6.

Title: Improvements in or relating to the manufacture of plastics coated webs
IPC: B32B37/15
Filed: 1961-02-15
Abstract: 982,758. Laminates and laminating. ST. REGIS PAPER CO. Feb. 15, 1961 [March 16, 1960], No. 32062/64. Divided out of 982,757. Heading B5N. [Also in Division D1] A method of coating a porous web 37, e.g. paper or woven or unwoven fabric, with a thermoplastic resin, e.g. polythene, a polyamide, a formaldehyde polymer, superpolyoxymethylene, or polypropylene, comprises drawing and stretching through an air gap from an orifice of a sheet extrusion die 33 a molten film 35 of the resin, by movement of the web past a coating zone where the film 35 contacts one side of the web, and applying suction at the other side to suck the film into the web. Suction is applied by a stationary chamber 29 connected to a suction pump 31 and located within a suction roll 25. Heaters 27a may control the temperature of the zone, and the web 37 may pass round a pre-heating roll 36 or be heated radiantly. One or both walls of the chamber 29 may be angularly movable, e.g. to 29c, see Fig. 5 (not shown). The coated web is passed around a cooling roll 27, is trimmed, if necessary, by disc knives 42, and passes to a wind-up roll. In a modification, Fig. 8, the web 68 passes over a stationary suction-box 60, an endless carrier screen 61 passing between the web and the box. A fixed perforated screen may replace the moving screen 61. In a modification of the apparatus of Fig. 8, see Fig. 10 (not shown), the suction box comprises two chambers in series, the extruder being located at a point between the two chambers. Slightly modified apparatus are described employing a suction-box, Fig. 11 (not shown), and suction rolls, Figs. 12, 14 (not shown), in which a layer of scrim is attached to a web of paper by the resin which overlies both, see Fig. 16 (not shown), the paper and the scrim being led past the extruder which deposits molten resin on the scrim. It is stated that the apparatus may be employed to produce a laminate in which the scrim is intermediate two paper webs, the lower surface of the upper web having the resin film applied thereto, see Figs. 17, 18 (not shown). The web 37 may be the same material as the coating, and may be perforated by a high voltage arc. Where adhesion of the coating would be assisted by oxidation the spacing between the extrusion nozzle and the coating zone may be increased.

Abstract: 1,145,466. Valves. ITT INDUSTRIES Inc. 14 July, 1967 [14 July, 1966; 23 Aug., 1966], No. 32461/67. Heading F2V. [Also in Division F4] A valve that allows regulated flow of hot or cold water to a heat exchanger (not shown) has a by-pass 8 taking water returning from the exchanger via inlet 6 to hot water outlet 5 so that the hot and cold water do not mix. In the position shown all the hot water entering inlet 4 flows to the exchanger via outlet 7 and back via inlet 6, by-pass 8 and outlet 5. When the spool is moved down to reduce the flow some of the hot water flows straight to outlet 5 through seat 15. After further downward movement to the central position of the spool, closures 11, 12 are both sealed and there is no flow to the heat exchanger. When the spool is moved downwardly again to permit cold water from inlet 3 to flow through the exchanger, closure 14 is seated and closure 9 opened to allow cold water returning from the heat exchanger via inlet 6 to flow through outlet 2.
