Title: Improvements relating to the feeding devices of envelope or bag making machines
IPC: B65H20/24
Filed: 1925-05-09
Abstract: 244,336. Hugo, T. May 9, 1925. Paper bags and envelopes, making. - In a machine for making paper bags or envelopes, a web 1 of paper fed continuously and uniformly from a roll by feed rollers 7 - - 10 is gripped by a presser 13 immediately before it is cut into blanks, and the slack thus formed in the web is taken up by a plate 27 operated by cam-actuated levers &c. 28 - - 32. As soon as the presser 13 rises, one or more pairs of feed rollers 11, 12, which have a surface speed greater than that of the rollers 7 - - 10, grip the web and feed it forward quickly, the plate 27 being meanwhile turned about its pivot 26 so as to allow the web to extend in a straight line from the rollers 9, 10 to the rollers 11, 12. The intermittent action of the rollers 11, 12 may be caused by cutting away a pair of one of the rollers or by raising the roller 12 periodically by a cam-actuated lever 19. The gear-wheels connecting the rollers 11, 12 may remain in mesh when the roller 12 is raised, so that both of these rollers rotate continuously.

IPC: B61H7/08
Filed: 1947-05-06
Abstract: 643,673. Electromagnetic track brakes. FREINS JOURDAIN MONNERET. May 6, 1947, No. 12170. Convention date, Dec. 12, 1946. [Class 103 (i)] The weight of an electromagnetic track brake, for emergency use in train and railway vehicles, is reduced to a minimum by using magnetic parts of high permeability, i.e. at least 200 for an induction of 1800 gauss, conductors capable of withstanding a high current density, such as 1000 amps per square centimetre, and insulated by materials having a very high heat resistance, such as the plastic materials known as " silicones." By combining these characteristics in multi-polar magnets, such as those shown in Figs. 4 and 6, the mean length of the magnetic circuit is reduced to less than three times the width of the rail bearing surface. Numbers of such magnets may be mounted on a single bar suspended below the vehicle as shown in Fig. 10.

Title: Process for hydrolyzing fats
IPC: C11C1/04
Filed: 1941-09-23
Abstract: 551,710. Splitting fats. PROCTER & GAMBLE CO. Sept. 23, 1941, No. 12333. Convention date, Oct. 30, 1940. [Class 91] In the hydrolysis of fat by countercurrent flow of fat and water in contact with each other under high temperature and pressure, the fat is simultaneously preheated and pre-saturated with water by injecting steam thereinto prior to the hydrolysis, the fat being maintained under sufficient pressure to cause the steam to condense. The fat is thus brought approximately to the temperature desired for the hydrolysis reaction, and is also preferably saturated with moisture at this temperature. The pre-treatment may be a batch or continuous flow operation. Saturated steam or superheated steam may be used. Free water in the fat at the end of the pre-treatment may be separated and as it is at the hydrolysing temperature it may be added to the separately preheated water to be used in the hydrolysis reaction. The pre-treatment is carried out in a separate high pressure vessel. In a modification, where separation of free water is unnecessary, the pre-treatment is effected in the lower part of the hydrolysing chamber by providing the latter with a perforated pipe or coil, arranged just below the dry fat admission level, and supplying the desired amount and quality of steam thereto. The pre-treatment may be effected in two or more stages, relatively low pressure steam being used in the earlier stages. Detailed examples are given of the steam pre-treatment and hydrolysis of tallow, acidulated cottonseed oil soapstock, and coconut oil respectively, a hydrolysing temperature of 475‹F. being used. U.S.A. Specification 2,156,863 is referred to.

Abstract: 884,472. Making grids for electron-discharge tubes. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 21, 1958 [April 24, 1957], No. 12555/58. Classes 83 (2) and 83 (4). A method of making grids for electron-discharge tubes by winding wire on backbones or support wires consisting in winding a grid, severing the end of the grid wire from the backbone and, after axial displacement of the grid backbones, winding the next grid, is characterized in that after winding a a grid, which involves feeding backbones longitudinally, at a speed necessary for winding the wire thereon with the desired pitch, by gripping the backbones by a first pair of jaws, a second pair of jaws is made to co-act with the first jaws so as to stretch the wound backbones between both pairs of jaws, the first jaws being then opened and moved axially along the backbones for the next winding operation, whilst the second jaws are opened to permit the wound backbones to pass therethrough for further processing. Grid backbones 3 from a reel 5 pass through a winding head 2 of the type described in Specification 743,828, to which reference is made, wherein wire is wound to lie in notches in the backbones which are then preened over to hold the wire, and, after a grid has been wound, the grid wire is broken off from its supply and then reconnected to the backbones some distance therealong from the wound grid to commence winding of the next grid. A slide 10 reciprocated by a cam 7 carries jaws 11a, 11b which grip the backbones 3 to feed them axially. At the end of the forward stroke of the slide 10 jaws 15a, 15b on a slide 14 close on to the wound backbones and, as the slide 14 moves forwards and with the jaws 11a, 11b still closed, the wound backbones are stretched between the two pairs of jaws. An electric current is passed through the backbones to heat them during stretching. The wound and stretched backbones pass through a chamber 19 supplied with reducing gas and then to shaping means in a housing 20 including members 21, 22, 23, 24 moved inwards to shape the grid by cams on the rotated housing 20, the grid being supported on a mandrel 25. The grid is cut off by cutters 44, 45. The shaped grid is stripped from the mandrel 25 by a member 37, as the mandrel is moved backwards, and carried off into a hopper or tray 38.
