Title: Improvements in coin-freed mechanism
IPC: G07F15/02
Filed: 1934-02-10
Abstract: 432,980. Prepayment mechanism for meters. WILSON GASMETERS, Ltd., G., Foleshill Road, Coventry, WILSON, J. H., The Mill House, and POOLE, D. C. E., The Elms, both in Baginton, near Coventry. Feb. 10, 1934, No. 4442. [Class 27] Coin action, thrust, and with delivery proportionate to value of coin.- In meter prepayment mechanism having separate slots in an angularly adjustable price-change plate for the insertion of coins of different denomination into a coin pocket, so as to displace a common member for selective engagement of a pair of quantity wheels, the different coins, are received into the pocket in planes which are inclined to each other, in such a manner that the coins have a common discharge point this ensuring that the delivery is strictly proportionate to the coin denomination for all sittings of the price-change plate. In the mechanism shown, two coin-slots f and g, for pennies and shillings respectively, are provided in the price-change plate a. These slots converge to a common outer point, and communicate with correspondingly arranged compartments in a member c, which is mounted on rods b<1> secured to a rotary carrier plate b, and which is adapted to be displaced radially against the action of springs e under the action of the inserted coins to effect the selective engagement of the quantity wheels. Coin-slit closing-devices.-Insertion of a shilling in the penny slot is prevented by an abutment h secured to one wall of the penny compartment c<1> in the displaceable member c. The front face of the abutment h lies at a distance behind the insertion slot, and the arrangement is such that a penny engages its upper edge so that the member c is displaced until the abutment h clears the insertion slot, as shown in Fig. 4, permitting full insertion of the penny. Coin-discharging mechanism.-The carrier plate b is freely mounted on the operating spindle b<3>, the latter having secured thereto a plate j<1> provided with a finger j<1> by which it drives the coin pocket. In the case of a penny, the finger j<1> engages over a recess c<5> in the member c, and holds it in the depressed position against the action of the springs e. This ensures that the penny is free to fall out when the coin pocket is turned to the discharge position. A second arm j<2> on the plate j returns the coin pocket to its normal position.

[Classes 97 (i), 98 (i), and 98 (ii)] Photographic material carrying a lightabsorbing layer, including photographic lightsensitive material, lens filter caps, and photographic safelight screens, is produced by applying to a support a layer of an aqueous solution of polyvinyl alcohol or a partially hydrolyzed polyvinyl ester, which contains a gelling agent having a light-absorbing effect or a gelling agent and a light-absorbing substance, allowing to gel, and drying. The gelling agent may be a dyestuff or may be otherwise capable of yielding a coloured layer as described in Specification 525,085. Coloured or colourless layers absorbing ultra violet light may be produced. Amides having an ohydroxyanilide structure such as #-naphthylsalicylamide, salicylanilide, di-(3-hydroxy-2- naphthoyl)-benzidide, 3-hydroxy-2-naphthoylarilide, disalicylbenzidide, and salicyl-2 : 5- dichloranilide act as gelling agents and absorb ultra-violet light. The compounds are used in alkaline solution. The layer may be an antihalation layer or an intermediate colour filter or a front ultra-violet absorbing layer in colour photographic material. Several examples are given. A coloured layer may be produced using Malachite Green-or other-dyestutf in conjunction with a colourless gelling agent such as resorcinol or with a gelling agent itself causing colour.

The second conduit (coil 36) may be temperature controlled. The sample flow is reversed by operation of valve 38, which connects conduit 36 to one of conduit 40 and 42 while admitting sample from the other of conduits 40 and 42 to conduit 52 for analysis at 54. In the embodiment of Fig. 2 (not shown), the remote ends of the second conduit coils are each connected to a T-junction, the arms of each T-junction being connected to a wash liquid supply and to segmenting gas. Segmenting gas in both embodiments may be removed through line 64 before the sample reached the flow cell. Alternatively a bubble detector may be used to detect the presence of a segmenting fluid bubble at 54 and to provide for viewing of the sample only in the absence of a bubble.

[Also in Division B8] In an hydraulic or pneumatic servomotor 2 for operating the clutch or brake of a motor vehicle under the control of a valve 9 which supplies pressure fluid to the right-hand side of a piston 1 for clutch or brake disengagement, the piston 1 itself controls the rate of clutch or brake engagement by sequentially blocking and opening ports 18, 19, 21. For clutch or brake disengagement the valve 9 is moved left by mechanical or electromagnetic means, which latter in the case of a clutch may be controlled by a push-button on the gear-shift lever, whereupon pressure fluid from a pump P moves the piston 1 left. On return of the valve 9 to the position shown, the piston 1 moves rapidly right under the action of a return spring until it blocks vent port 19 just prior to clutch or brake engagement whereupon pressure fluid on the right of piston 1 passes through lines 22, 20 and a restrictor R to vent thus showing the piston 1 during initial clutch or brake engagement. Subsequently the piston 1 opens port 21 thereby establishing unrestricted communication between the two sides of piston 1 through lines 20, 22 so that the piston completes its movement rapidly. A by-pass duct 16 between inlet and outlet ports 13, 14 may be omitted when continuous fluid circulation is not required. In Fig. 7, the restrictor comprises a valve spool 27 which is normally urged left by a spring 28 to provide restricted communication between ports 25, 35. When fluid pressure at 24 which may be a function of engine speed exceeds a predetermined value the valve spool 27 moves right to provide a less restricted communication 36 between ports 25, 35. The spring pressure may be adjusted by a screw 29.
