Title: Improvements in and relating to Belt Gearing applicable to Sewing Machines.
Inventor: FAIRWEATHER WALLACE
IPC: D05B69/16
Filed: 1918-05-23
Abstract: 128,699. Fairweather, W., (Singer Manufacturing Co.). May 23, 1918. Sewing-machines, driving; stopping-gear, non- automatic.-In a power-transmitter for sewing- machines comprising relatively movable driving and driven pulleys and a brake disk, the movable pulley is operated positively by two cams, one at each end of its spindle, which passes from side to side of the transmitter. A driven pulley 31 mounted on a shaft 32 extending through a fixed bearing-sleeve 22, is moved axially so as to engage frictionally either a fixed brake disk 27 or a driving-pulley 19 rotating on the outside of the sleeve 22. The shaft 32 is moved by cam surfaces 39 on arms 38, which are rocked simultaneously by a treadle operating on an arm 40. A spring 42, readily adjustable by a nut 45, is mounted on a pin 43 connected to one of the arms 38 to return the cam surfaces when the treadle is released, thus bringing the pulley 31 against the brake disk to stop the machine. A hanger 8 by which the apparatus is suspended below a table 1 is. moved along a horizontal rod 4 to vary the tension of the driving-belt 20 A fine adjustment is obtained by rotating a rod 6 formed with a screw thread 7 engaged by a pin 14 mounted in the hanger, and the tension can be quickly relieved when the gearing is disengaged by moving the rod 6 end-ways by a cam-ended lever 17, which is also used to rotate the rod. In a modification, the brake disk is secured to the upper part of the hanger 8, and the cam 39 operates through a slot in the disk against a ball seated at the end of the shaft 32. Guards.-A dress-guard 47, a portion of which is seen in Fig. 3, covers the pulleys on one side, and is pivoted to a lug 48 on the hanger 8. It is held against its raised or lowered positions by a spring 49. Fig. 9 shows a modification in which the guard g swings sideways on a vertical pin 62, the lower end of which lies in a recess in a lug 61 on the guard. By raising the guard slightly it can be turned about the pin Lubricating.-To lubricate the bearings of the pulleys oil from a well 51 is raised by a loose ring 52 resting on the hub 21 of the pulley 19, and passes through channels 54. 56 to lubricate both surfaces of the sleeves 22. It then passes along an inclined channel 56 to lubricate a ball-thrust bearing 25 and returns to the well. Specification 101,761 is referred to.

Patent GB-492681-A (GB)
Title: Improvements in or relating to metallizing surfaces
IPC: G11B7/26
Filed: 1937-03-25
Abstract: To prevent the deposition of metal on selected portions of surfaces which are to be metallized by thermal vaporization in vacuo, the selected portions are treated with an organic liquid or semi-liquid, preferably of boiling point above 150 DEG  C., which liberates vapours when heated in vacuo.  The material may be a hydrocarbon, e.g. an oil or grease, a halogenated hydrocarbon, a polyhydric alcohol such as glycerine, a resin or a wax, and it is preferably applied as a very thin layer, e.g. by printing or impressing.  By this means designs may be produced by printing either the design or the negative of the design; bands or strips may be printed in this way to form advertisements on wrapping paper &c.  Bands or strips of insulating-material such as paper can be metallized for use in the construction of electrostatic condensers, one or both edges of the band and also marks at definite lengths being kept free from metal by greasing them prior to metallizing.  Resistances comprising a meandering strip of metal on an insulating-material, e.g. paper, can be made by greasing the places which are to remain free of metal.  By forming by similar means longitudinal metal strips on a strip of insulating-material, e.g. paper, and winding up the paper, disc coil windings may be produced.  In making kinematograph films the picture to be projected is applied to a transparent film band in the form of a metal design, the places to be kept free from metal being first printed with grease &c., and the film then treated with metal vapour. For sound-film records an oil-bearing member is caused to oscillate in contact with the film band to form an oil track corresponding to the sound oscillations and the band then exposed to metal vapour in vacuo.

Title: Planet gear with automatically variable ratio of gear
IPC: F16H3/00
Filed: 1920-03-25
Abstract: 140,792. Landis & Gyr Akt.-Ges. March 25, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Turning-gear.-Epicyclic gearing is combined with a ratchet clutch N and a detent M so that a shaft D may drive a shaft A at reduced speed, or the shaft A may drive the whole device solid. The device may be applied to start an internalcombustion engine from the shaft D of an electric motor, or may be used as a hand starting-gear. Planet gears G<1>, G<2> supported between a disk B secured to the shaft A and a disk F loose on the shaft D mesh with a sun gear J upon the shaft D and with a loose internally-toothed ring H. The clutch N prevents the ring H from turning faster than the disk F, and the detent M prevents the ring H from turning backwards. When the shaft D starts to drive, the gears G<1>, G<2> roll round on the ring H, which is fixed, and drive the shaft A. When the shaft A begins to drive, the ring H springs forward and engages the clutch N, and the gearing turns solid. The clutch N is a ball friction clutch. The detent M acts positively as shown in Fig. 2. When overrunning, the balls M are thrown by centrifugal action into pockets N' in the ring H.

Title: Production of pentadecanedioic acid
IPC: C07C51/285
Filed: 1953-04-01
Abstract: A method of producing pentadecanedioic acid and its alkali metal salts comprises treating an alkyl ester of 15, 16-dihydroxyhexadecanoic acid containing up to four carbon atoms in the alkyl group in acetic acid solution with lead tetraacetate, trilead tetraoxide or sodium bismuthate as oxidizing agent at a temperature of about 20 to about 65 DEG  C. to form an aldehyde and heating the aldehyde to not more than 65 DEG  C. with an aqueous alkaline solution of hydrogen peroxide and alkali metal hydroxide. The free acid is obtained by decomposition of the alkali metal salt with a strong acid.  In examples: pentadecanedioic acid is obtained by oxidizing the methyl ester of 15, 16-dihydroxyhexadecanoic acid in acetic acid with lead tetraacetate, extracting methyl aldehydopentadecanoate from the reaction product, warming the former with hydrogen peroxide and sodium peroxide in water and acidifying the product with hydrochloric, sulphuric or nitric acids (1) and (2); in a similar process red lead is employed instead of lead tetraacetate (3). Specification 738,420 is referred to.
