Abstract: 568,805. Ticket-issuing machines. BELL PUNCH CO., Ltd., WEAVES, A. O. E., and WEBB, C. F. July 12, 1943, No. 11250. [Class 106 (iii)] A portable machine is formed of one or more units and each unit comprises a casing serving as a container for one or more rolls of consecutively numbered tickets, means whereby a single or double length ticket may be issued, and means for over-printing or cancelling the serial number or other marking on one portion of a double length ticket whenever such length ticket is issued. As shown in Figs. 1 to 3 a casing 1 contains a supply roll 2 the free end of which extends upwardly around a feeding drum 4 and over a platen 6 beneath a stamping or printing device to a delivery slot 8. The drum 4 is formed with radial projections 10 and the feed is effected by a spring-controlled lever 12 having a toothed quadrant 15 engaging a pinion 16 to which is attached a ratchet wheel 18 that co-operates with a pawl 19 pivotally mounted on the drum, the movement being effected upon release of the lever 12 under the action of the spring 20. Overthrow and counter-rotation of the drum are prevented by stop pawls 21, 22 and a detent wheel 24. For single length tickets the downward movement of the lever 12 is limited by a stop arm 28 arranged to engage a pin 29 on the lever. A push button 32 is employed to move the arm 28 to the dotted line position, Fig. 1, when a double length ticket is to be issued. To impress an identification mark or stage number on the ticket type wheels 34 and an impression lever 38 are provided. For cancellation marking, a fixed' type bar 35 and a second impression lever 37 is provided. The levers 37, 38 are raised in the downward movement of the operating lever 12 by by-pass pawls 42, 43, thereon engaging rollers 41 on the levers 37, 38. For single length tickets the lever 38 only is operated. The stage number stamping or printing means is movable laterally to vary the location of the imprint to distinguish ordinary return, single and workmen's return tickets. For this purpose the ticket strip has three sections and the particular section is selected by axially moving the type wheel spindle which has three grooves 46, 47 and 48 one or other of which is arranged to engage a spring loaded plunger 45. An inking ribbon or carbon strip is preferably provided between the ticket strip and the type wheels. A counter may be provided for registering the number of double length or value tickets.

This means may comprise a screw 25 threaded through a bracket 24 on the underside of the seat portion, the screw providing an adjustable lost motion connection between the link 19 and the seat portion. On tilting of the seat the lost motion is first taken up, screw 25 then abuts link 19 such that the seat portion and link rotate in unison. In the second embodiment, the linkage is a parallelogram and the means for controlling the tilting of the seat portion relative to the upper link comprises a link 51 parallel to link 19, pivotally secured to the upper and lower links and having an upward and forward extension 52 which carries a roller 53 engaging with the underside of the seat portion. A foot rest 57 may be connected to the parallelogram linkage such that in tilting of the seat portion, the foot rest moves from a leg supporting position in front of the seat to a substantially vertical position below the seat.

Abstract: 1,214,848. Electro-chemical analysis cells. GEORGE KENT Ltd. Dec. 9, 1968 [Dec. 21, 1967], No. 58128/67. Heading G1N. In a cell for coulometrically determining the concentration of oxygen in a gas, the gas is made to flow through a gas-permeable graphite electrode structure 8, one side of which, which flanks the gas flow path through the electrode structure, is separated by an ion-permeable insulative polyamide membrane 29 from a sintered nickel and cadmium electrode 30, the electrodes and membrane being dampened, but not saturated, with an aqueous KOH electrolyte. As shown, the cell is disc-shaped. Incoming gas in humidified as it passes radially outwards over an annular wick 6 dipped into a KOH reservoir 5. The gas then flows radially inwards through the electrode structure 8 which thereby offers a reducing flow path crosssection comensurate with the reducing oxygen concentration of the gas as it flows therethrough. The gas then flows radially outwards again over a stainless steel mesh electrode 33 and exits through outlet 40. The third electrode 33 is separated from electrode 30 by another ion-permeable polyamide membrane 31 and is maintained more positive than electrode 30 so that some of the hydroxyl ions liberated at electrode 8 pass right through electrode 30 to the third electrode 33, thereby prolonging the active life of electrode 30. A platinum wire electrode 25, sealed in glass 26, is provided to generate oxygen at a known rate for calibration purposes.
