Abstract: 318,046. Strathern, W. R. Oct. 31, 1928. Controlling variable-speed gearing.-Variablespeed gearing comprising alternatively engaged clutches such as A - - D, Fig. 1, or alternatively engaged sliding gears, is controlled through pairs of solenoids 14 from a governor 39 on or geared to the driving-shaft 1. The governor is shown upon countershaft 2, the variably driven shaft being shown at 1'. The governor 39 is connected by a lever 28 and link 27 to a lever 26 of a switch S, Fig. 4, through which the solenoids 14 are controlled. The so'enoids are in pairs, one to engage and one to disengage each clutch, being connected to rock shafts 10, the wiring being such that each clutch is disengaged before the next is disengaged. The clutches A, B &c. may be of the kind engaged by the locking together of three gears 4<1>, 4<2>, 4<3>, Fig. 2, as described in Specification 308,495. In operation, the engine being started, the driver of, say, a vehicle actuates a manually operated switch on the dashboard to bring the governor-controlled switch S into circuit with a. battery. On engaging a pedal-operated engine clutch, the switch S acts to energize a solenoid to bring in the lowest speed. That speed is disengaged and a higher speed engaged, until there is equilibrium. Acceleration of the engine brings in a higher speed, and deceleration a lower speed.

Title: Heat-sealing of vinylidene chloride resin films
IPC: B29C65/48
Filed: 1959-09-17
Abstract: 885,676. Seaming non-metallic sheet materials. GRACE & CO., W. R. Sept. 17, 1959 [Sept. 18, 1958], No. 31788/59. Class 42 (1). A process for heat-sealing vinylidene chloride polymer films which shrink on heating comprises overlapping two surfaces of said heatshrinking films, applying slight pressure and heating the overlapped surfaces below the melting point of the film to form a seal. It is stated that the process forms a seal having high shear strength and that this is considered surprising in view of the fact that shrinkage is one of the most disruptive effects and would break asunder any normal seal. At least one of the surfaces may be plasticized and preferably the plasticizer content is 6 to 12% of the weight of one ply of the film, the temperature is preferably between 160‹ and 195‹ F. and the pressure between 1 and 15 p.s.i. In the apparatus shown a vinylidene chloride polymer film 4 unrolls from a roll 2 and is passed between a support 6 and a wick 8 and receives a surface coating 10 of a plasticizer. The film 4 then passes to a tube former 24 where the overlapped edges are first subjected to slight pressure between rollers 26 and 28 and then to heat from a radiator 30. Specification 816,931 is referred to.

Abstract: 621,170. Feeding webs; preventing set-off. JONES, K. W. Oct. 31, 1946, Nos. 32351 and 33098. [Classes 100 (i) and 100 (ii)] A pneumatic bar 1 for controlling the movement of paper passing through a printing or like machine, and which is connected to an exhauster when used for tensioning the paper and to a source of pressure when used to prevent set-off, is constructed with a number of grooves 3 of small cross-section, each having communication as by an aperture 2, Fig. 2, with a tube 4 connected to the source of pressure or vacuum, the arrangement being such that the pneumatic action is not materially affected if a web is used which does not cover all the slots 3. The slots 3 are eccentric as shown in Fig. 2, being readily cut in a lathe. A similar arrangement is applied to the air passages 7, Fig. 3, of a bar 6 which is of flat form with the slots 3 formed in a convex surface 6. In Fig. 5 the slots 3 are formed in separate rings 16 which are adjustably mounted on a tube 15 formed with apertures 17 with which the apertures 2 of the slots 3 can be put into or out of register, retaining means being provided to hold the rings in operative or inoperative position. In a modified form the rings are arranged only at the extremities of a fixed central member, the slots 3 of which are in constant communication with the tube 15. In a further modification the tube 15 is formed with a stepped aperture and the outer slots 3 are cut off successively by adjustment of the outer bar 1 relatively to the tube 15. Instead of providing radial apertures 2 the apertures may be formed by cutting the grooves 3 deep enough to penetrate into the interior of the bar 1. Helical grooves may replace the circumferential ones, and each ring or segment may have two grooves of opposite hand crossing one another with the aperture 3 located at the point of intersection.

Title: New or improved method of ascertaining or comparing the density or translucency of photographic images and apparatus for use in connection therewith
IPC: G03C5/02
Filed: 1928-11-07
Abstract: 326,201. Bell, C. E., and Scott, L. G. Nov. 7, 1928. Photometric apparatus.-A photographic image is prepared from an original having a key-tint applied thereto and a measure of the image density is obtained by comparison of the density of the key tint reproduction with a standard. The key tint, which may be an adhesive grey tinted paper tab or a U-shaped clip c of metal such as copper tinted by a deposited coating of chromium, is preferably applied to a corner of the original a. The invention includes apparatus such as that shown in Fig. 6, for measuring the density of the key tint reproduction. The lamp n, the casing h of which is adjustably mounted on the post g, projects a light beam down the telesoopic tube r, s, through the small aperture t in the top of the base j', on to a selenium cell, photo-electric cell, or thermo-electric detector u. The corner of the negative to be tested is inserted between the base f and the bottom of the tube s. Felt washers 3 and a fibre strip 2 prevent leakage of external light to the sensitive cell. The exposure of the sensitive cell is controlled by the roller blind shutter v, w. A galvanometer for indicating the density of the keytint reproduction is connected in series with the detector. The source of light n is maintained constant independently of variations in the voltage supply by variable resistances and further lamps which may be included in the circuit if necessary. A voltmeter measures the voltage supplied to the lamp n. The method may be used to test whether images of the required density have been obtained in photo-engraving, photo-etching and multi-colour printing processes. Where the original has been photographed without a key-tint, the image of some light part such as the sky may be taken as the key tint reproduction.
