Cutting glass.-Apparatus for severing glass cane or tube comprises a motor-driven cutter mounted on a frame pivotally connected to each of two discs rotating in unison. The glass 10 is fed into the machine by chains 11 and is carried past guides 48, 49 to the cutting position. The disc cutter 28 is driven directly from an electromotor 27 mounted on a frame 26 pivoted on upstanding pins on discs 25, 23 which rotate in the same direction. An anvil 32, Fig. 6, is advanced to press the tubing &c. against the cutter 28 by a cam on the frame 26 which actuates a slide 35 connected to the anvil, by adjusting screws 36, 45 and a link 40, pivoted on a pin 41 to the fixed frame. After scoring the glass is broken by a spring-urged adjustable cracking-lever 52, 53 pivoted on a pin 51 and actuated by an arm 54 mounted rigidly on the frame. Two sprockets supporting the tractor chains are driven through gearing from an electromotor 17 which also drives the toothed disc 23 geared through an idler 23<1> to the disc 25. In operation the glass is continuously fed by the chain 11 and is supported by the anvil while scored by the rotating cutter, which moves along axially with the glass and also through the path of the latter. The cracking- lever then severs the glass which rolls down a delivery shoot 57. In a modification specially adapted for severing cane glass, the frame 26 carries a spring-urged striker which is cocked and released for dividing the cane by a stationary cam.

Title: Improvements in or relating to butterfly valves
IPC: F16K1/228
Filed: 1969-05-07
Abstract: 1,273,240. Valves. JAMESBURY CORP. 7 May, 1969 [28 May, 1968], No. 23229/69. Heading F2V. A butterfly valve has a closure disc 13 formed as a segment of a conical surface which, in the closed position co-operates with a flexible seat formed from, e.g. a fluorine-containing polymer, having a portion 15 which is deflected by fluid-pressure to form a seal, and is arranged so that it deflects more when the pressure acts from the top in Fig. 3, than when the pressure acts in the opposite direction, so that the seat can seal on to the disc whatever side the pressure acts up to a maximum limiting design pressure of the valve. In Fig. 3 the difference in deflection is achieved by placing pivot points 30b and 31 at different radial distances from the centre of the disc but it can also be obtained by forming the seat with a graduated stiffness from one surface to the other. The valve has a motorized operator 11a.

Title: Apparatus for transversely stretching and guiding sheet material
IPC: B29C55/08
Filed: 1950-09-22
Abstract: 690,835. Feeding webs. AMERICAN VISCOSE CORPORATION. Sept. 22, 1950 [Dec. 9, 1949], No. 23253/50. Class 100(i) [Also in Group VIII] An apparatus for transversely stretching and guiding travelling sheet material, comprises an arcuate roll rotatably mounted on a carriage pivotably mounted on an axis approximately through the mid-point of the roll and in a plane which is perpendicular to the plane of travel of the sheet material, means for swinging the carriage about its axis, control means for actuating the carriage swinging means and means connecting the control means to the carriage for moving the control means in response to the swinging movement of the carriage. A web of regenerated cellulose passes under a guide 3 which holds the web down on a laterally adjustable perforated saddle 4, then over an arcuate roll 5 which stretches and guides the web laterally before being wound into a roll. The roll 5 comprises a fixed curved shaft 56 and series of rollers 57 freely mounted thereon by ball bearings and separated by brass discs 61, while being enclosed by a sleeve 62 of rubber, regenerated cellulose, cellulose ethers or esters, synthetic resin, or fabric. The rollers are rotated by the sleeve 62 and the end rollers secured to pulleys 30 preferably driven at a slightly higher speed than the web. The shaft 56 is supported by a carriage 19 mounted on rollers 24 at each end and pivoted at its centre to a support 27 by a pivot 26. Lateral deviation of the web carries an opening 34a in the saddle 4 to be uncovered by the web, thus admitting air through a flexible tubing 36 and a pipe 35 to a chamber 11 having a diaphragm 14 secured to a rod 15 connected to one end of the carriage 19, the chamber being connected to a vacuum line 12. Lateral deviation of the web in one direction causes the carriage 19 and roll 5 to be swung by movement of the diaphragm in a direction to compensate for such deviation. The saddle 4 is rotatably mounted in a black 50 and is oscillated by movement of the carriage 19 through a rod 41, bell crank lever 38, and a link 37, such that the web is guided with a limited amount of transverse travel determined by nuts 2 and 22 engageable with a fixed plate 23. The web is therefore wound up, in the case of a web having thickened marginal portions with such portions staggered laterally of the completed roll which does not therefore have thickened ends. In order to deal with webs of varying width, the saddle and guide 3 may be laterally adjustable. If it is desired to wind a roll having straight sides the saddle 4 is locked and disconnected from the carriage to prevent it oscillating in response to the swinging movement of the carriage.
