Title: Improvements in adjusting devices, suitable for brake rigging
IPC: B61H15/00
Filed: 1945-06-02
Abstract: 628,106. Hydraulic slack-adjusters for brakes. ROUMENS, J., and FLOURY, R. June 2, 1945, No. 13910. Convention date, May 24, 1944. [Class 103 (i)] [Also in Group XXIV] The slack in brake-operating rigging is automatically increased or decreased by altering the length of a liquid column D disposed between two members 1 and 6 connected to the control means and to the braking means respectively. During the initial operating period before the brake-blocks meet the wheels the pressure in chamber D is insufficient to open valve 10 so that the members 1 and 6 move integrally. If there is insufficient slack the brake blocks meet the wheels before the flange 23 meets the fixed stop 24 and the pressure in D rises to open valve 10 so that liquid flows from D to G through passage 13 so increasing the slack. This continues until the flange 23 meets the fixed stop 24, so pulling spring-biassed piston 17 to the right, permitting valve 8 to close chamber D and lock members 1 and 2 in adjusted relation. If the rigging is too slack the flange 23 meets the stop 24 before the brakeblocks meet the wheels so that valve 8 is closed before valve 10 is opened and piston 4 moves integrally with cylinder 1 since chamber D is closed while piston 17 is held and displaces liquid from F through valve 15 to E. During the return stroke this displaced liquid is forced by spring-biassed piston 17 through valve 20 into D while liquid flows from G into F, so that slack is taken up. If the rigging is correctly adjusted flange 23 meets stop 24 and the brake-blocks meet the wheels simultaneously so that valve 8 closes as valve 10 opens while the piston 17 is not appreciably displaced. To obviate formation of a void in chamber G this chamber may be connected to a reservoir containing liquid or liquid and air. Several valve constructions reducing the number of valves and springs needed and several casing constructions are described.

Title: Improvements in or relating to mirror script printing or manifolding apparatus or machines
IPC: B41L11/00
Filed: 1935-05-15
Abstract: 456,762. Copying documents. RITZERFELD, W., 107, L³tzowstrasse, Berlin. May 15, 1935, No. 14203. [Class 100 (ii)] In a mirror-script manifolding-machine for line-by-line or sectional printing, the forme- or master-sheet-carrying drum, in addition to being rotatable with its supporting shaft, is movable stepwise therealong and relatively to a rotatable counter-pressing roller and a surface moistening device for the card &c. to be printed upon. The forme drum 3 has a spring- controlled clamping device arranged to be flush with the drum surface when holding the mirror-script master-sheet to the drum, and the lines of printed matter run circumferentially thereof. The step-by-step movement given to the drum to bring the lines thereon into the moistening and printing position is automatically effected by a feed rack 21 slidable in the spindle 4 of the drum 3 and passing through a slot in the drum, which is thus held against rotation relatively to the spindle but can slide thereon. A cam 25 engaged by a roller 23 on the rack 21 moves the rack to the left through the space of one line of print, at the end of a printing operation and this movement is imparted to the drum by a pawl 26 fixed thereto. The return of the rack is effected by a spring but the drum is held in its adjusted position by a second pawl 29 engaging a rack 28 fixed to the shaft 4. The pawls 26, 29 can be raised and locked in this position when the drum is to be returned to its initial position. A counterpressing roller 5 carries a rubber strip 6, the diameter of the roller and strip being equal to that of the drum. A moistening device comprises a container 15 furnished with a strip of wick 16 which is moved towards the roller 5 when a card is fed, the container being mounted on a shaft 18 which is rotated by a cam fixed to the gear-wheel 9 driving the shaft 4. The wick 16 is raised from the roller 5 against the action of a spring, at the time this roller is in a position to take a fresh card from the feed table ; at the same time a spring- pressed gripper bar 10 on the roller is held open by a cam 11 so that a fresh card to be printed may be attached to the roller. Upon rotating the roller 5 by power or by means of a crank 7, the gripper 10 grips the fresh card as the gripper shaft passes off the cam 11 and the wick 16 moves into a position to moisten the appropriate strip of card. After printing, the gripper 10 is opened and the card falls on to a table. In order to permit various spacings between the lines on the master sheet, a variable feed movement may be imparted to the rack 21 by mounting the member 25 so as to be adjustable to different positions giving different amounts of feed or this member may be stepped and adjustable ; alternatively, the arm 24 supporting the roller 23 may be adjustable relatively to the cam 25.

Abstract: 915,325. Audiometers. TEGNER, C. A. E., and ANDERSON, E. H. April 22, 1960, No. 14253/60. Class 81 (2). An audiometer which incorporates a transistor oscillator and amplifier in order to ensure compactness, these being fed from a battery, has a manually operated interrupter switch, for keying the oscillator, connected in the main supply lead from the battery. By this means the battery power is conserved during the time that the test tone is not required. In the form described, the transistor 31 functions as an oscillator in combination with a tuning coil 38, the frequency being selected by a manuallyoperated switch 40. The switch also actuates a second selector 34 which connects one of a range of resistors 35a, 36a, 37a across the oscillator output to ensure that the level is constant irrespective of the frequency in use. The second transistor 27 is connected as an amplifier and a further selector switch 23 determines the final output fed to the earpiece 22. The power supply from the battery 15 is keyed by an interrupter switch 7 and a filter combination 20, 21 is connected across this to suppress transients.
