Title: An improved sheet registering mechanism
IPC: B65H9/10
Filed: 1933-03-13
Abstract: 398,746. Feeding sheets. MILLS, C. K., 34, High Holborn, London.-(Cross Paper Feeder Co. ; 185, Summer Street, Boston, U.S.A.) March 13, 1933, No. 7590. [Class 100 (i).] In a sheet-feeding apparatus the sheets S are registered laterally against a side gauge 70 by means of rollers 12, 53 or other devices which are actuated by resilient means, or other forms of stored power, which cease to move the sheet after it has engaged the member 70, so that buckling and marking of the sheet by the rollers is prevented. The roller 12 is freely mounted on a shaft 10 supported by a bracket 5 carried by a bar 2 secured to the side frame 1 of the frame of a conveyor which advances the sheets to the front stops of the machine. To the roller 12 a torsion spring 15 is secured, the spring being also connected to a collar 18 secured in an adjustable manner to an extension 17 of the shaft 10. For each passage of a sheet the roller 12 is rotated against the action of the spring 15 by means of a reciprocating slide 25 actuated by a cam 30 and operating on an anti-friction roller 24 mounted on a pin 23 secured to the roller 12. The sheet is controlled by guides 7, 47, and when it reaches the front stops an upper roller 53 which is carried by a reciprocating slide 39 is lowered on to the roller 12 so as to grip the sheet between the rollers 53, 12, and the slide 25 is then retracted by the cam 30 so that the roller 12 rotates under the action of the spring 15 and moves the sheet against the gauge 70. The slide 39 is actuated by a cam 61 and a bell-crank lever 56, 57, and the guide 47 moves vertically with the slide. Projections 47a on the guide 47 engage grooves 72 in the gauge 70 to prevent the edge of the sheet from passing between the guide 47 and the gauge 70.

Patent GB-577315-A (GB)
Title: Improvements in and relating to control systems for power driven apparatus
Filed: 1941-05-11
Abstract: 577,315. Control of D.C. motors. TUSTIN, A.. and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 11, 1941, Nos. 7970/42 and 7971/42. Divided out of 577,309. [Class 38 (iii)] An object, e.g., a gun, is moved by a motor under the control of a hand-controller, the arrangement being such that the torque developed by the motor depends both upon the actual position of the controller and upon the velocity with which it is adjusted from one position to another ; the torque may also depend upon the acceleration imparted to the controller when it is being adjusted. The controller, Fig. 1, is of a dynamometer type, movement of a handle 1 causes relative movement of outer and inner cages 25, 44, the relative displacement of which controls the magnitude of a resistance, and the displacement of which is controlled by a spring 19 and eddy current brake 21. The resistance controls the excitation of the main field 70, Fig. 3, of a " Metadyne " supplying the motor 65. Another field 71 is energised according to the back E.M.F. of the motor and according to the position of contact 61 on the controller. Limit switches 74, 75 increase the effect of the winding 71 as the gun approaches limiting positions. A fly wheel may be placed adjacent to the eddy current brake 21 so as to introduce a component dependent upon acceleration and this fly wheel may be connected to its shaft through a slipping clutch so as to limit the maximum permissible torque. Modifications include the use of an ordinary Ward-Leonard system ; the insertion of amplifiers in the control circuits ; the use of a tachometer generator to obtain the component dependent on velocity and the application of the system to other motive equipment. Specification 577,309 is referred to.

Title: Process for the preparation of trichloroethylene
Inventor: CLAIR RENE
IPC: B01J19/00
Filed: 1970-02-20
Abstract: 1,269,013. Trichloroethylene. PRODUITS CHIMIQUES PECHINEY-SAINT-GOBAIN. 20 Feb., 1970 [21 Feb., 1969], No. 8231/70. Heading C2C. Trichloroethylene is produced by continuous introduction of liquid 1,1,1,2-tetrachloroethane, or a chlorohydrocarbon feed containing 1,1,1,2- tetrachloroethane, into a metallic reactor to effect dehydrochlorination at 135-250 C. and 1.5 to 10 bars pressure in order to maintain ebullition of the liquid phase in the reaction zone. The reactor is preferably a thermic siphon evaporator with an array of tubes heated by a heat transfer fluid and is made of iron, pig-iron, steel, or another iron alloy, e.g. Monel (Trade Mark) or Inconel (Trade Mark). A constant level of liquid in the reaction zone is maintained by continuous and regular addition of the feed and/or bleeding off liquid. The gaseous reactor effluent may be passed through a first condensation column to condense chlorohydrocarbons having a higher boiling point than trichloroethylene, these being recycled to the reactor, and then through a second condenser to condense trichloroethylene, some of which may be recycled, leaving hydrogen chloride as gaseous effluent. Alternatively the gaseous reactor effluent may be fed to a heat treatment furnace with no solid filling for further thermal decomposition of chloroethanes in the vapour phase. In this embodiment a small amount of the furnace feed is purged to eliminate tarry residues. The liquid reactor effluent may be distilled to recover trichloroethylene, and the residue recycled, or may be fed to a heat treatment furnace having no solid filling for further thermal decomposition of chloroethanes in the vapour phase. Perchloroethylene is produced in embodiments involving vapour phase dehydrochlorination.
