Title: Improvements in or relating to Machines for Operating upon Heel Lifts.
IPC: A43D83/00
Filed: 1918-06-18
Abstract: 128,392. British United Shoe Machinery Co., (United Shoe Machinery Corporation). June 18, 1918. Heels and top lifts, machines for.-Machines for operating upon heel lifts, such as attaching, building, or compressing machines, are provided with mechanism to feed the lifts automatically to the operating means. The invention is described as applied to a top lift compressing machine in which the usual lift-feeding clamp 16, Fig. 3, is mounted to slide over a bracket 14 bolted to a vertically-movable head 12, which carries the usual compressing dies 10: The bracket 14 has secured to it a support 20 for a magazine 22 loaded with top lifts, which rest on a pair of plates 38, Figs. 2 and 3, secured to the support 20. The plates are spaced apart for the passage of a pusher 42 carried by a slide 40 to which the rear end of the clamp 16 is secured. As the slide advances, the pusher separates the lowest lift and forces it under a spring-pressed plate 46, which is carried by a bridge 44 mounted on the plates 38. The pusher, continues to move forwards until the lift drops off the plates 38 on to a carrier plate 58 secured to the slide 40. The pusher is then retracted, and the carrier plate is moved from under the lift, which drops into the clamp 16. A pair of fingers 64 on the plates 38 guide the lift while it is on the carrier plate, while a stop 66 adjustably secured to the bridge 44 prevents the lift from advancing too far. The top face of the pusher 42 is inclined, as shown at 60, so that as the pusher is retracted it will raise the lifts in the magazine; this agitation on each stroke of the pusher prevents the lifts from sticking together. The magazine comprises two complementary trough-shaped sections 24, 26 arranged to overlap where they engage the breast portions of the lifts; the section 26 is adjustably secured to the support 20, while the two sections are connected together by bolt-and-slot connexions 36 to allow the section 24 readily to be removed from the machine. When one section 24 is removed, a second similar section carrying a stack of lifts is substituted for it; a retainer 68, Fig. 6, supports the lifts in the section while it is being carried about and applied to the machine, but is removed before the feeding of the lifts commences.

Title: Improvements relating to the control of alternating-current electric motors
IPC: H02P1/46
Filed: 1921-04-08
Abstract: 165,072. Metropolitan - Vickers Electrical Co., Ltd., (Assignees of Drake, C. W.). June 17, 1920, [Convention date]. Systems for alternating current motors only.-Synchronous motors are started on reduced voltage and automatically switched on to full voltage by devices responsive to the fall of current traversing the field circuit, which takes place when synchronous speed is reached. The Figure shows a starting arrangement for a 3-phase synchronous motor 1 supplied first from a reduced-voltage source 7 and afterwards from a full-voltage source 4, and having its field-magnet excited by a separate source connected to slip-rings 14. By the closure of a starting push-button 27 and a no-voltage circuit-breaker 24, a solenoid 10 conects the motor to the low voltage source, and causes the energization of a solenoid 16 tending to actuate a change-over relay 15. The change-over action is prevented by an opposing solenoid 17, connected across the field circuit, which becomes ineffective when synchronous speed is reached. The response of the change-over relay cuts out the solenoid 10 and brings in a solenoid 11, which connects the motor to the full-voltage source.

Title: New substituted acetone dicarboxylic acid compounds and production of an aliphatic keto-alcohol therefrom
IPC: C07C59/90
Filed: 1955-04-14
Abstract: The invention comprises di-esters of monoallyl acetone dicarboxylic acid, the free acid and its alkali-metal and alkaline-earth metal salts.  The esters may be prepared by reacting a diester of acetone carboxylic acid with an allyl halide in the presence of an alkaline condensing agent and an inert organic solvent, under anhydrous conditions.  Reaction may be effected at raised temperature and if desired under pressure. The esters used as reagents are preferably those having up to 5 carbon atoms, such as the methyl, ethyl and propyl esters, and the condensing agent is suitably an alkali metal alcoholate.  When allyl chloride is used as reagent it is preferably present in excess.  The resulting allyl acetone carboxylic acid esters may be saponified with an aqueous solution of a basic alkali metal or alkaline earth metal compound, e.g. sodium or lithium carbonate or an hydroxide of sodium, potassium, lithium or barium to give the corresponding salts of allyl-acetone dicarboxylic acid which may be isolated, e.g. by addition of a lower aliphatic alcohol. Aqueous solutions of the salts may be acidified to liberate the free acid which is then recoverable, e.g. by acetone extraction. Alternatively the aqueous solutions of the salts may be reacted with pyruvaldehyde at a pH from about 6.5 to 9.5 to form the corresponding salts of 1-allyl-2,5-diketo-4-hydroxyheptanoic acid which may be isolated by precipitation with a non-solvent, e.g. methanol or by drying the solution in the frozen state under vacuum.  The free acid may be obtained by cooling an aqueous solution of the salt to near its freezing point, adding dilute acid with agitation and freeze drying the acidified solution.  The free acid decarboxylates at room temperature to nona-8-ene - 2,5 - dione - 3 - ol, which may be cyclized with dilute alkali to allethrolone.  The acyclic ketonic alcohol may be obtained direct by acidifying the aqueous solution of the metal salt of the heptanoic acid to a pH of about 1.0-2.5 with a mineral acid, followed by extraction with a water-immiscible solvent, preferably in the presence of a neutral water-soluble solvent.  In examples: (1) allyl bromide is reacted with a methanolic solution of dimethyl acetone dicarboxylate and sodium methoxide under reflux and the resulting mono-allyl dimethyl acetone dicarboxylate is isolated; the ester is then saponified with aqueous KOH, the product neutralized with sulphuric acid, pyruvaldehyde is added, the pH adjusted to 7.5-8.0 and the mixture stirred at room temperature; the resulting aqueous solution of 1-allyl-2,5-diketo-4-hydroxy heptanoic acid sodium salt is acidified with HCl to pH 2 with evolution of CO2; the resulting nona-8-ene-2,5-dione-3-ol is isolated.  (2) Allyl chloride (3 molar proportions) is reacted with dimethyl acetone dicarboxylate and sodium methoxide as in (1) to give dimethyl mono-allyl acetone dicarboxylate.
