Title: Improved sheet feeding and guiding apparatus for typewriters
IPC: B41J11/48
Filed: 1921-03-08
Abstract: 176,666. Fairweather, W. C., (Underwood Typewriter Co.). March 8, 1921. Sheet feeding, clamping, and guiding arrangements; paper-shelves.- In a device for facilitating the filling-in of short bills, a shelf 5, arranged at the front of and above the platen 2, is provided with clips 6 for holding the bill 1, and is associated with a vertically adjustable gauge. The bill 1 is inserted downward at the front of the platen, and the top edge is then pushed beneath the clips and into contact with the gauge, the latter being in its lowest position; after each line has been written, the gauge is raised and the top edge of the bill is pushed into contact therewith. The shelf is formed with a side guide 25 for the bill. A record sheet 26 may pass round the platen and receive single or multiple line-spacing in the ordinary manner. Long bills are passed round the platen and gauged at the top edge by the gauge. The gauge may consist of a flange on a plate 8 which is disposed between the shelf and a supporting-bar 9 therefor, and is formed with inclined slots 14 receiving pins 13 on the supporting-bar. On pushing laterally a knob 19, the gauge is raised, the successive positions being determined by a spring- pin 15 which enters holes 16, 17, 18 in the gauge. Horizontal parts are formed at the ends of the slots 14. The clips may be secured by screws 39 and dowels 40 to the supporting-bar. The supporting-bar is secured to brackets 41 which are secured to bars 44 on the platen-frame by screws 45 entering holes 46, the brackets being secured in a position corresponding to the depth of the bill-heading. For setting the gauge parallel to the printing-line, the bar 9 is secured to the brackets 41 by screws 42 passing through slots 43.

Abstract: 939,840. Moulding containers. LABORATOIRES VIFOR S.A. Feb. 26, 1962 [May 18, 1961], No. 7477/62. Class 87(2). A sealed liquid filled container is formed by injection of the liquid into a preferred slug to expand it against the walls of a mould. Horizontal turntable 1 carrying a circumferential series of electrically heated initial moulds 2 and finishing moulds 3 is indexed between a lower synthetic resin injection device, Fig. 16 (not shown) and an upper liquid injection device. Table 1 is lowered to engage the nozzle of the synthetic resin injection device against initial mould 2 which is closed by head portion 174 through which needle 192 of the liquid injection device is introduced into the cavity 24 to be surrounded by the injected synthetic resin. The table 1 is raised to disengage from the synthetic resin injection device and the liquid injection device is raised retaining the preformed slug within head 174. Table 1 is indexed and to enable the preformed slug to be deposited within a finishing mould 3. Obturator 204 of the liquid injection device is raised to permit the injection of precompressed liquid, Fig. 9 (not shown). After withdrawal of needle 192 and head 174 the container within mould 3 is indexed to an intermediate position to set whilst injection of a fresh preformed slug takes place into an initial mould 2. Upon the subsequent indexing of table 1, a sealing device, Fig. 12 (not shown) is lowered to melt the top of the container which is then sealed by a descending punch. Alternatively, Fig. 15 (not shown) the sealing device may utilise direct contact of an electrically heated sapphire head. The filled and sealed container is then ejected upon indexing the table 1. Refrigerated water cooling is provided at the base of the electrically heated synthetic resin injection device, within container clamps, Fig. 14 (not shown) and to the chamber 254 and punch 262 of the sealing device. The table 1 is indexed and locked and the synthetic resin injection device and container sealing device actuated by hydraulically operated members, Figs. 7 and 4 (not shown) and the table 1 and the telescopic fluid injection assembly are vertically actuated from a hydraulic piston assembly concentric with the axis of rotation of the table 1.

Title: Improved electric device for ham slicing machines
IPC: B26D1/143
Filed: 1944-04-24
Abstract: 581,844. Driving slicing-machines. MACDONALD, J. April 24, 1944, No. 7532. [Class 28 (ii)] The usual hand turned flywheel A of a slicing machine is adapted to be driven by an electric motor A<11> through belts and speed-reducing pulleys A<6> and A<15> on a countershaft A<7>, The motor and countershaft are mounted on opposite sides of a pivot A<19> of a crossbar A<9> so that normally the weight of the motor &c. overbalances the weight of the countershaft and pulleys so. that the pulley A' is tipped up high enough to make the belt A' slack so that it does not drive and at the same time the bar A' moves the screw d<6> up so that brake d' is applied to the handwheel. To start the drive, the handle A<91> is pushed down which lowers the countershaft and pulley A' into belt driving contact and at the same time allows the brake d<1> to come off. A screw 14 adjusts the motor position to adjust the belt tension. A grooved rim A<1> for the belt is clamped on the flywheel rim. The arrangement is mounted on height adjustable legs clamped to a horizontal angle bar carrying a board or platform a' on which the slicing machine B rests, the weight of the machine being sufficient to hold the board down on a counter or table. Specification 377,225 is referred to.

Title: Improvements in hydraulic valves
Inventor: SPARROW ALAN WYCLIFFE
IPC: F16H61/14
Filed: 1967-02-17
Abstract: 1,214,821. Valves; friction clutches. PERKINS ENGINES Ltd. 14 Feb., 1968 [17 Feb., 1967], No. 7579/67. Headings F2C and F2V. A valve which may be used to control the operation of a lock-up clutch in a hydrokinetic torque converter includes a valve member 7 movable in a valve chamber 6 between first and second positions to regulate the flow of hydraulic actuating fluid to the clutch, and a spring 11 arranged to urge the valve member towards the first position and to apply a decreasing force to the valve member as it moves towards the second position. In the preferred embodiment, the valve is actuated by centrifugal force and moves outwardly to engage the clutch at a higher rotational speed, than that at which the spring is able to return it to its inner position. The speeds at which outward and inward movements occur may be 1800 and 1200 r.p.m. respectively. A pin 10 carried by the valve member is clipped within a looped end 12 of the spring 11 which has its free ends notched for engagement with a pair of knife-edged struts 14. A spring clip 17 and an interchangeable domed washer 18 limit the travel of the valve member which may be used to admit fluid under pressure alternately to opposite sides of a clutch plate or to one side of the plate only when the latter is spring-loaded to either the engaged or disengaged position. Disengagement of the clutch plate may also be effected by blocking flow through one part of the valve to create a centrifugal head. The outer ends of the struts 14 may engage cantilevered leaf springs while the inner ends engage the lower end of a short shaft having a ball-jointed connection with the valve member. The lower end of the shaft may alternatively be engaged by the inner ends of inclined coil or U-springs the outer ends of which are located in shoulders on the valve body.

Abstract: A bright-drying coating composition consists essentially of a solution of (1) monocamphylpolysiloxane and (2) a volatile liquid organic solvent.  The siloxane is generally used in amount of from 1 to 20 pts. (by wt.) per 100 pts. of total solution.  The camphylsiloxane may contain minor amounts of other Si-bonded hydrocarbon groups and alkoxy or hydroxyl groups.  Solvents specified are turpentine, mineral spirits, Stoddard's solvent, kerosene, ethylene glycol monoethylether, diethylether, n-butylether, beta-chloroethylether, isopropyl alcohol, 2-ethylhexanol, n-butyl alcohol, chlorothene, cyclohexane, decane, cyclohexene, toluene and xylene.  The compositions may also contain from 0.1 to 5 parts (per 100 pts. of solution) of a wax, e.g. beeswax, spermaceti, paraffin wax, Japan wax and Gersthofen V-wax. Other optional ingredients are shellac, perfumes, dyes, pigments, insecticidal and bactericidal agents, and additives to aid in spreading the solution.  In the example, monocamphylpolysiloxane coatings are compared with monocyclohexylpolysiloxane coatings.  The camphyltrichlorosilane (C10H17SiCl3) used to prepare the camphylsiloxane used in the example, was made by reacting in a bomb at 188 DEG  C. for 20 hours, a mixture of camphrene, trichlorosilane and chloroplatinic acid in isopropyl alcohol, with subsequent distillation of camphyltrichlorosilane under reduced pressure, as described in U.S.A.
