Title: Pwoer supply testing fabric guide device for a sewing machine
IPC: G01R31/50
Filed: 1974-05-15
Abstract: 1452193 Testing electrical equipment INTERNATIONAL BUSINESS MACHINES CORP 15 May 1974 [25 June 1973] 21510/74 Heading G1U The independent power supplies 22-28 of a known data processing equipment 10 are tested by operating the processing equipment 10 to load the supplies in a predetermined manner and monitoring a valve in the equipment to detect a fault. The monitoring system 50 takes a signal from an external store 46 and monitors high frequency components via band pass filter 54, similarly low frequency components 56 and the D.C. level of the signal in positive and negative threshold detectors 66, 68. Any monitored component above a predetermined level provides an output to one of the AND gates 70-80 which are enabled during a test procedure by the control decoder 38 via latch 82. The gate outputs pass to a register 84 which feeds the monitor output back into the processing equipment.

Title: Process of preparing cyclohexanone from cyclohexanol
IPC: C07C45/00
Filed: 1961-06-14
Abstract: Cyclohexanone is produced by dehydrogenating cyclohexanol containing acid impurities, e.g. cyclohexanol obtained by oxidation of cyclohexane, in the vapour phase in the presence, as catalyst, of zinc oxide and carbonate, or a mixture of zinc oxide and carbonate with an alkaline earth metal or magnesium oxide and carbonate.  Acid impurities specified are formic acid, valeric acid, butyric acid, propionic acid and acetic acid which may be combined with the cyclohexanol in the form of cyclohexyl esters. The dehydrogenation is preferably effected at a temperature between 400 and 450 DEG C. U.S.A. Specification 2,334,445 is referred to.

[Class 141.] Gloves of a fireproof or flameproof character are cut out from material by a method in which, before the cutting out operation takes place, parts of the material are gathered and stitched in the form of gussets which are afterwards let out. The glove is indicated in its finished form in Fig. 1, and in Fig. 4 is shown a pattern for cutting out. The glove comprises an outer skin 6, Fig. 3, of finely woven asbestos cloth, an inner skin 7 of coarser asbestos cloth, and fibre packing 8 which is quilted in position to prevent creeping. A lining 9 is provided of close grained leather. The seams are formed by asbestos piping 16 overstitched by asbestos yarn 17. A constricted sleeve portion is formed in the mouth of the glove to prevent the entrance of flames or the like. The pattern for the outer skin, shown in Fig. 4, is identical with that of the inner skin with the exception that the latter does not extend below the wrist line a a. In making, the pattern is pinned on the cloth attached to the work table by pinning along the line a, a and the tuck A marked, taken in and stitched temporarily to give extra room for the thumb. By attaching along the line c, c the tuck B is marked and taken in and the same procedure is adopted with respect to the line d, d and the tuck C, the cloth for the latter being drawn from the palm portion. Finally, the tuck D is marked off and taken in.

Abstract: 208,745. Hoe & Co., Ltd., R., (Hoe & Co., R.). Aug. 11, 1922. Delivery apparatus comprises an endless carrier travelling over a number of piles arranged in line at one end of the machine and having sheet-taking grippers, a number of devices being provided, one for each pile, for actuating the grippers to release, successive sheets over different piles. The sheets, cut from a web W by the cutting-cylinders 4, 5 and carried along by grippers on endless chains 9, are deposited alternately on four pile supports 54, the sheets marked a, b, c being deposited on the piles 24, 25, 26, 27 respectively. Over the several piles are mounted gripper - controlling devices 28, 29, 30, 31, all movable except the last. Each movable gripper-controlling device comprises a cam shoe 37 on an arm 38 pivoted on a shaft 39, which has rigid thereon an arm 49 connected to a spring rod 50 and a second arm 40 connected by a rod 42 and bell-crank lever 43, 45 to a rod 46 terminating in a yoke 47 carrying a roller 48 engaging a cam on the shaft 35.

Title: Process for the separation of isomeric menthane decarboxylic acids
Filed: 1954-07-30
Abstract: Isomeric menthane dicarboxylic acids are separated from a mixture, obtained by the catalytic addition of carbon monoxide and hydrogen to a menthadiene of formula C10H16 with simultaneous or subsequent hydrogenation and subsequent oxidation of the dimethylols so obtained, by a process comprising subjecting the mixture of dicarboxylic acids to solvent extraction with a mixture of heptane and pentanone.  Preferably a mixture containing 5 parts by weight of heptane per part of pentanone is used.  In the examples: (a) dipentene is diluted with heptane and is treated with water gas under pressure in the presence of an aqueous cobalt sulphatemagnesium sulphate solution, the resulting mixture is then hydrogenated to give a menthane monomethylol fraction and a dimethylol fraction which is oxidized with a mixture of chromic acid and glacial acetic acid, the mixture obtained is neutralized and then treated with mineral acid to bring the pH value to 2 and the emulsion obtained is extracted with benzene which is subsequently distilled off and the remaining dicarboxylic acids are separated by treatment with a mixture of pentonone and heptane.

Abstract: 189,219. Reilly, T. A. Aug. 24, 1921. Labelling.-A card or like tube over the end of which a paper label is to be secured, is placed in a carrier, at the bottom of which is placed the label which has gummed projecting lugs; the tube is then forced downwards so as to carry the label between devices which press the lugs against the sides of the tube. The tube 19 is held between four adjustable fingers 34 carried on a table 32, intermittently rotated by a ratchet gear. At the bottom of the fingers 34 are pads 37 which receive gum from an intermittentlyrotating roller 66, over which they are carried by the movement of the table 32. A pile of labels 48, Fig. 7, is pressed against these pads by a spring push rod 50 operated by a cam 49, so as to leave the uppermost label adhering to the pads. The pile of labels is held in position by rods 45 sliding in a friction grip on the block 39 carrying the pile of labels. The rods 45 strike against stops 55 on the table 32, so as to keep their upper ends flush with the top of the pile of labels. The rods 45 and stops 55 are adjustable to suit labels of different sizes. The table 32 then carries the tube and label under a plunger 78, Fig. 11, which forces the tube and label into a guide 70 which folds the lugs of label against the sides of the tube. The tube is then forced bv the next following one between brushes 88 carried by spring-pressed blocks 73.
