Abstract: 674,223. Glass rods and tubing. SCHULLER, W. April 20, 1949 [April 20, 1948], No. 10933/48. Class 56. Glass tubing e and glass rods of multiple layers of glass or with coloured glass stripes are formed by the continuous up-drawing of a rotating glass batch a to which an additional glass batch d, of other composition or different colour or colours, is fed at the same rotating speed through a double walled cylinder 5 having its lower edge dipping into the glass batch a. The cylinder 5 is rotated with the pot 4 by means of teeth 7 and consists of external and internal parts 8 and 9 which surround an annular cavity 10 and are connected at 11. The glass d, with the same or nearly the same coefficient of expansion as glass a, is fed into the cavity 10 and is sucked into the forming position b, forming a coat 14 completely covering the tubing e. The lower edge of the part 8 may be immersed more or less than that of the part 9. The apparatus may be provided with a water &c. cooling device 15, as shown, or with a device operated with a gas coolant. The lower edge of cylinder 5 may be provided with a floating protective ring 25 which is not secured thereto, and the ring may be spaced from the cylinder so that heat passes from the space round the cylinder in the direction of arrow B, as shown in Fig. 7, and prevents the batch d from chilling. The tube or rod is given a coating in the form of one or more stripes by using a cylinder 18 which has, instead of the annular cavity 10, a cavity 19 extending over a part of the circumference only, or a number of spaced cavities such as 21. With such cylinders the glass d is conveniently fed from a spoon or funnel to each cavity. The apparatus shown in Fig. 7 has a nozzle 27 with bore-hole 28 through which air is blown to form the tubing. The apparatus for forming rods is similar but does.not include the nozzle and borehole.

Title: Improvements connected with rotary printing machines
IPC: B41F31/30
Filed: 1950-05-08
Abstract: 693,040. Printing machines. HALLEY & SONS, Ltd., J., and HALLEY, A. M. May 4. 1951 [May 8. 1950] No. 11317/50. Class 100(ii) Inking apparatus.-A rotary printing machine is provided at each side with a lever pivoted on the axis of a duct roller and pivotally connected at each end to a lever carrying a distributing roller, means being provided to vary the effective length of the link connection between the levers to change the relative setting of the two rollers together with means for changing the setting of the distributing roller about the axis of the duct roller. The lever 6 pivoted on the duct roller 7 has an upturned arm pivoted to the downturned arm of a lever 9 in which is mounted one end of a distributing roller 10. Parallel to the lever 9 is a subsidiary lever 11, a drive pinion for the roller 10 being placed between the levers 9, 11, Fig. 2 at each side of the machine. The free ends of the levers 6, 9 are interconnected by a link 12 the effective length of which can be varied by rotating a pin 13 by means of a knurled plug 14 having an eccentric portion fitting within the link 12. By varying the length of the link, the clearance between the rollers is adjusted. The plug 14 can be locked at any required setting by a nut 15. The connection between the lever 6 and the link 12 can be released by means of a pin 16 having an eccentric portion rotatable in the link 12. This pin 16 is also a pivot for a link 17 and has a head 18 with a radial arm 19 whereby the pin may be rotated to part the rollers. The link 17 is pivoted on a pin 20 carried by an arm 21 projecting from a shaft 22 mounted in bearings 23. At one end of the shaft 22 is an arm 24 in which is mounted a rockable block 25. Passing through the block is a screwthreaded spindle 26 engaged in a rockable stud 27 fixed to the machine. By rotating the spindle 26 the shaft 22 is turned, whereby, through the link 17, the levers 6, 9 are rocked about the axis of the duct roller 7 to adjust the clearance between the roller 10 and a printing cylinder 28 without change of the relative setting of the rollers. Thus the machine can be adjusted for printing cylinders of different diameters. By means of a knurled head 29 the pin 20, which has an eccentric portion within the link 17, can be rotated to change the effective length of the link 17 and so adjust the parallelism between the roller 10 and the printing cylinder.

Title: Improvements in or relating to the recovery of acetylene from gas mixtures containing the same
IPC: C07C7/11
Filed: 1941-09-08
Abstract: Acetylene is separated from admixture with other gases by a process which comprises contacting the gaseous mixture with a selective solvent for acetylene and subsequently liberating the absorbed acetylene by freezing the solution.  The preferred solvents are those which contain oxygen or nitrogen atoms or both, one or more of which are capable of readily losing electrons (electron donor atoms).  A particularly useful class of compounds are those keterocyclic organic compounds containing in the ring at least two oxygen atoms, at least two nitrogen atoms, or at least one each of such atoms.  Compounds mentioned include glycol carbonate, ethylene derivatives of N-methyl carbamic acid and N,N1-dimethyl urea, glycol oxalate, ethylene derivatives of N,N1-dimethyl oxamide and N-methyl oxamic acid, glycol ether ester of glycollic acid, ethylene derivative of glycolic acid N-methyl amide, dioxane, N - acetyl-, N - formyl-, N - carbo - methoxy-, N - carboethoxy-, N - carbopropoxy-, and N - methyl - morpholine, N : N1 - dimethyl pyrimidine, diglycolide, N-methyl-succinimide, acetonyl acetone, furfuryl acetone, acetophenone, gamma-pyrone, dimethyl carbonate, N-dimethyl carbamic acid methyl ester, tetramethyl urea, dimethyl oxalate, N-dimethyl oxamic acid methyl ester, tetramethyl oxamide, N : N1-dimethyl amide of glycolic acid methyl ether, dimethyl acetamide, glycol diacetate, paraldehyde, ethylene glycol acetal, ethylidene ether ester of glycolic acid, anethole and safrole. The preferred solvent is dioxane.  It is an advantage to absorb the acetylene at super-atmospheric pressure, and to recover it at diminished pressure. Examples are given to show the efficiency of the process.

Title: Improvements in and relating to coin-freed package vending machines
IPC: G07F11/54
Filed: 1940-07-11
Abstract: 540,470. Coin-freed vending machines. HAGSTROM, J. E. July 11, 1940, No. 11526. [Class 27] In a vending machine packages or bottles 12 are arranged in an annular path or paths, a fixed or rotary guard plate 46 above the bottles is provided with perforations 48 through which the bottles may be withdrawn, and a turntable 26, rotating about a vertical pivot 34 and having a delivery aperture 36, is given a step-by-step rotation through coin-freed mechanism so that after each step the turntable aperture 36 is brought into register with one of the perforations in the guard plate to permit the withdrawal of one bottle or package. In the construction shown in Figs. 1 to 4, the guard plate 46 is fixed and is provided with three rings of perforations 48 each above a bottle 12. The bottles are placed in holes 19 in a carrier 18 secured by brackets 20 in a refrigerated casing 14. The guard 46, turntable 26 and coin mechanism 56 are all carried by the lid 22. When a coin is inserted at 54 and a handle 82 pulled a pinion 44 gearing with the turntable is rotated through a certain angle and the turntable is rotated correspondingly, so that the turntable aperture 36 is brough into register with one of the perforations 48 as shown in Fig. 2, and a bottle may be withdrawn. All the other perforations 48 are wholly or partly covered by the turntable. The turntable is locked against movement, except that determined by the insertion of a coin, by means of (1) two ratchet pawls 90 which limit its rotation to one direction only, and (2) the pinion 44 which is locked until a coin is inserted. The turntable aperture 36 is normally closed by a lid 38. In a modification the guard plate 46 has concentric rings of perforations 48 which are not as numerous as the bottles and are therefore widely spaced, the guard plate being rotated by the coin mechanism about the same axis as the turntable but in the opposite direction thereto, in such a manner that at each operation of the handle 82 the turntable aperture 36 is in register with one of the guard plate perforations 48 which is immediately above a bottle so that the latter can be withdrawn. Coin-action, mechanical connection.-The coin 52 passes down a shoot 50 to the position shown in Fig. 3, in which it rests in a slot 72 in a rotary plate 70 and in one of a number of radial slots 74 in a ratchet disc 64 which is secured to the pinion 44 and is normally locked by a spring-loaded pawl 66. Thus the coin locks the plate 70 to the disc 64. When the coin is in both slots it acts on a cam plate 92 on the pawl 66 and forces the latter back to free the disc 64. A reciprocatable bar 80 carries a roller 86 engaging a slot 88 in the plate 70, so that when the handle 82 on the bar 80 is pulled the plate 70 is rotated and with it the disc 64 and pinion 44. At the limit of movement of the rod 80 the coin is in register with a slot 76 in the lid 22 and drops into a coin box not shown. The rod 80 is returned to its normal position by a spring 84.

Abstract: 1431007 Automatic voltage control HONEYWELL INFORMATION SYSTEMS Inc 14 March 1974 [5 April 1973] 11529/74 Heading G3R A circuit for providing firing signals for controlled rectifiers in a regulated power supply includes a controllable current source, and a Schmitt trigger circuit, the output of which is connectable to the controlled rectifiers through an OR-gate, another input of which is connectable to the regulated output. As shown in Fig. 2, a capacitor 74 is charged by a current source circuit 67 in response to a signal at a terminal 63 representing an error signal derived from a measured value of the output voltage of a D.C. supply circuit including silicon controlled rectifiers and isolating transformers, Fig. 1 (not shown). The rate of charging of capacitor 74 determines the frequency of pulses produced by a generator circuit 1 5 and fed to the SCR's by a triggering circuit 14 including a pair of flip-flops 96, 97, thereby controlling the output voltage of the supply circuit. The generator circuit 15 includes a Schmitt trigger circuit 89 which delivers a high voltage until the voltage on the capacitor 74 reaches a threshold level, at which point the output level of trigger circuit 89 decreases rapidly, producing a low level output from an OR-gate 85 and allowing capacitor 74 to discharge through diode 76. The presence of an inverter 88 ensures that a positive-going pulse is delivered to the trigger circuit 14. An OR-gate 84 acts as a latching device. A one-shot circuit 92 connected to the output of inverter 88 provides a minimum time delay between output pulses by actuating another OR-gate 86 to prevent simultaneous conduction of more than one SCR. A similar disabling function is provided by an AND-gate receiving inputs from flip-flops 96, 97 and a terminal 62 connected to one of the isolating transformers. Operation of circuit 15 may also be inhibited in response to over-current and over- and under-voltage sensing circuits, (Fig. 1).
