Title: Improvements in or relating to strip feeding and severing method and apparatus
IPC: B41L1/14
Filed: 1942-09-30
Abstract: 560,468. Delivering sheets for cutting &c. WILLIAMS, W. P. (Standard Register Co.). Sept. 30, 1942, No. 13746. [Class 100 (i)] [Also in Group VIII] For severing into single sheets strips of printed forms such as cheques, utility bills, sales strips, &c., in which the individual sheets are connected by pre-weakened transverse lines, the strips 4 formed with edge perforations 4a for engagement by pins 9 on rollers 8 are fed past slitting discs 12 which trim off the edge portions containing the feed perforations. The trimmed strip is then passed to a tearing device comprising rollers 30 fitted with rubber tyre-like portions 31 driven at a greater speed than the strip, which during the tearing operation is raised by a camoperated pivoted or sliding table 21 so as to grip the strip against a roller 27 fitted with tyre-like discs 28 driven at the speed of the pins 9, and also preferably after a slight interval against the roller 30 which is driven at a faster speed and is preferably constructed with portions 31 of slightly differing diameters, or as a slightly conical roller, so that tearing commences at one edge and travels in succession across the strip. The position to which the table 21 drops when released by its cam 23 to its inactive position is controlled by an adjustable eccentric stop 26. The shaft 24 of cam 23 is driven by change-speed gears so as to allow the table to be vibrated more or less rapidly to adjust the apparatus for dealing with longer or shorter sheets. A guide 34 directs the severed sheets to a delivery table, and extends to the entrance rollers so as to guide the strip into the machine. Another guide directs the trimmed edging 14 out of the machine. The roller 31 may be replaced by a fixed sector which grips the strip while it is being torn. The strip is temporarily buckled during this action, but the buckle straightens out.

Patent GB-217247-A (GB)
Title: Process for the manufacture of the cardiac glucoside of bulbus scillae
IPC: C07G3/00
Filed: 1924-06-10
Abstract: The glucoside of squill (Bulbus Scillae) is isolated by first obtaining the tannin compound of the glucoside present in aqueous solutions of squill by shaking with an organic solvent not miscible with water and concentrating the organic solution.  The tannin of the compound is next liberated by adding a soluble tannin-precipitating agent, such as lead acetate and subacetate or zinc acetate, to a solution of the tannin compound in a mixture of water and an organic solvent, such as methyl alcohol, ethyl alcohol or acetone, and the excess of tannin-precipitating-agent eliminated from the filtrate in known manner, say by addition of disodium phosphate.  The resulting solution is then evaporated to dryness in vacuo and the glucoside extracted from the salt-containing residue by means of an organic solvent, such as chloroform -5 per cent methyl alcohol, which is finally exaporated to dryness.  If insoluble tannin-precipitating agents, such as magnesium oxide, ferric hydroxide, lead oxide and hydroxide or aluminium hydroxide, be used, the subsequent purifying operations are unnecessary.  Examples of the solvents employed in the extraction of the tannin-glucoside compound are methyl and ethyl acetate, methylethylketone, chloroform or other halogen hydrocarbon, such as carbon tetrachloride, ethylene dichloride or ethyl bromide, to which is advantageously added a little of an organic solvent miscible with water, such as methyl and ethyl alcohol or acetone. The Specification contains examples of the processes and describes the properties of the product.

Filed: 1918-09-04
Abstract: 125,866. Innocent &. Son, H., and Cooper, T. Sept. 4, 1918. Interconnecting guard with starting-gear.-A guard for punching-machines, presses, &c., is connected with the starting-treadle, and the machine cannot be started if the descent of the guard is obstructed by the fingers of the operative, &c. When the machine is at rest, the treadle a is held raised by a spring a' and, through link-work and a two-fingered pawl g acting on a lever h, holds in a raised position the guard l surrounding the tool. When it is desired to start the machine, pressure is applied to the treadle to withdraw the finger g<1> of the pawl g from the lever h, and if the guard l is free to descend, the lever h is caused by a spring to follow the finger g<1> and the pedal is free to descend. If, however, the descent of the guard is obstructed, the lever h does not follow the finger g<1>, and the finger g<2> of the pawl comes in contact with the curved lower end of the lever h and prevents depression of the treadle. A second pawl i with a projection i<1> may be raised by the finger g<2> to engage the end of the lever h when the finger g<2> fails to do so.
