Abstract: 268,963. Baker Perkins, Ltd., and Pointon, J. E. April 8, 1926. Bakery plant; proving appliances.-In breadmaking plant of the type wherein a continuous oven b and a prover a are arranged for operation in series, the loaves or dough portions being carried in a circuitous path through the prover and oven on an endless chain conveyer d to provide for the production of either tin or ovenbottom bread, as may be desired, the conveyer is so directed that in travelling from the prover to the oven it brings the portions into a position g where they can be transferred to that part i of the conveyer about to enter the oven whereas the conveyer proceeds from such position to the oven entry in a looped or circuitous course. For ovenbottom bread the dough portions are proved when they reach the position g, and. in order that the trays e receiving the transferred portions at the position i may be hot, heating elements m are arranged above the conveyer at the part approaching the position i. An adjustable pulley carrier o provides means for varying the period of proof of the dough portions when producing tin bread. In a modified form of the apparatus the looped portion of the conveyer is guided by guide-wheels and a fixed curved track, and by adjustable pulleys in the first part of the prover provision is made for varying the period of proof of the dough portions for both oven-bottom and tin bread.

Abstract: 993,885. Making electric circuits. ELECTROLUX A.B. March 12, 1962 [March 30, 1961], No. 9395/62. Heading B3A. [Also in Divisions H1 and H2] A method of making electric circuits comprises stamping, punching or the like a metal plate to form depressions on one side of the plate and elevations on the other, and removing the elevations to form spaces whereby the remaining sections of the plates form the conductors of the circuit. An electrically conductive metal plate 20, of, e.g. copper, is stamped to produce depressions 22 of a depth greater than the thickness of the plate, corresponding elevations 21 and holes 25. Alternatively the plate is stamped so that the elevated portions are attached to it by thin connecting portions. The stamped plate is fastened by casting or adhesive to an electrically insulated base 26, of e.g. plastic or oxidized aluminium plate, or to a conductive base in which case the plate is given an insulating surface prior to fastening. Prior to assembly the depressions 22 are filled with powdered talc or chalk to prevent them from being filled with jointing material. After fastening the elevations 21 are removed by turning, face-milling, grinding or by tearing off along the thinned portions and the talc or chalk removed from the gap thus formed by brushing. In a modification tabs (not shown) are stamped out of the plate and cast or bent about the base 26. A rotor, Fig. 12, comprises two circular stamped discs which are attached back to back with an insulating layer therebetween, e.g. a base 26, by rivets 32 and machined to form conductors 24 and spaces 27. The plates may be stiffened by embossing or stamping prior to or after assembly.

Title: Improvements relating to electric welding
IPC: B23K9/22
Filed: 1923-04-11
Abstract: 196,285. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of MacFarland, A. M.). April 11, 1922, [Convention date]. Welding.-In welding-machines in which the work-pieces are heated to a melting temperature and united by percussive engagement, a pilot arc is struck between the work-pieces prior to the establishment, of a welding arc of relatively high intensity and means are pro.vided to maintain the work-pieces in pressure contact after their percussive engagement. The work-pieces 23, 22 are mounted in holders 2, 21 the former of which is stationary, the latter being carried by a lever A whose angular movement is controlled by an eccentric 6 whose pin is constrained to move in a horizontal line by means of a block 9 and a fixed guide 7. A second lever 5 is provided with a member 12 which rests on a finger 11 carried by the eccentric. This lever carries also a carbon contact 17 registering with a corresponding contact 18 which may be vertically adjusted by a screw 20. The wiring is as shown, 32 being a source of welding current, such as a battery, welding transformer or a condenser; 16 is a solenoid and 28 an automatic switch. In operation the eccentric is set with the handle 10 turned clockwise so as to bring the work-pieces into contact. The main switch 26 is then closed thereby closing the welding circuit through the resistance 33 and energizing the solenoid 16. This results in a downward pull on the solenoid plunger 14 and a corresponding movement of the member 12, which rotates the eccentric in an anti-clockwise direction thereby separating the work-pieces and striking the pilot arc. The continued downward movement of the lever 5 closes the welding circuit through the contacts 17, 18 a heavy rush of welding current being thus obtained owing to the shunting of the resistance 33. Meanwhile the continued rotation of the eccentric once more forces the work-pieces into contact to complete the weld, after which the circuit is broken by opening the switch 26. The separation of the work-pieces and their percussive engagement may be effected by means of a spring- actuated hammer in combination with a cam device; or the finger 11 may be actuated directly by the solenoid. The welding-circuit contactmembers may be manipulated and timed electrically.

Title: Glycol ester derivatives
IPC: C07C69/68
Filed: 1935-03-30
Abstract: Alkoxy esters of acylated hydroxy acids are obtained by treating a hydroxy carboxylic acid containing one or more carboxylic groups with a glycol ether to esterify all the carboxyl groups, and then esterifying the free hydroxy groups with an aliphatic monocarboxylic acid.  Suitable hydroxy acids include lactic, malic, citric, tartaric and saccharic acids, and suitable ethers include the methyl, ethyl, butyl or other alkyl ethers of ethylene glycol or diethylene glycol. The monoethers of propylene or dipropyleneglycol may also be used. For the esterification of the hydroxy groups in the original acid, acetic acid or anhydride or propionic and butyric anhydrides may be used.  The products are stable and may be used as plasticizers.  The butyryl derivatives are less soluble in water than the acetyl derivatives. According to examples: (1) 4 mols. of tartaric acid and 8,5 mols. of the monobutyl ether of ethylene glycol were heated, using 0-1 per cent of sulphuric acid as catalyst.  Water formed was removed with benzene and the reaction completed at 158 DEG  C.  8,3 mols. of acetic anhydride were added and the mixture boiled at 130 DEG  C. for two hours.  Excess acetic acid and anhydride were removed by distillation under reduced pressure.  The product was di-(butoxyethyl)diacetyl tartrate.  (2) In a similar manner, 2 mols. of citric acid and 8 mols. of monomethyl ether of ethylene glycol were esterified, and the product then esterified with 3 mols. of acetic anhydride.  The product was tri-(methoxyethyl) acetyl citrate. (3) 12 Mols. of monomethyl ether of diethylene glycol were esterified with 85 per cent 10 mols. of lactic acid, using 1 per cent of aluminium sulphate as catalyst at a temperature of 95--140 DEG  C. Excess ether was distilled off and the product esterified with 12 mols. of butyric anhydride at a temperature of 170--150 DEG  C.  The product was b -ethoxy ethoxy ethyl butynyl lactate.
