Title: Improvements in photographic materials
IPC: G03C1/765
Filed: 1946-01-31
Abstract: 613,134. Photographic materials. KODAK, Ltd., JANUS, J. W., RAY, A. A., and HANCE, G. Jan. 31, 1946, No. 3130. [Class 98 (ii)] To facilitate recognition of the non-emulsion bearing side of a sensitive photographic material, the rear surface of the support is provided with a layer having smooth and matt areas so arranged that the matt areas can be readily recognized by touch, e.g. in alternate strips. This touch-recognizable layer may be produced on the rear of the support, i.e. a film support or a glass plate, by (1) first coating the support with a smooth layer and then either coating parts of it with a matt layer to form a pattern or spreading over selected areas a powder, which may be of the same composition as the binder of the smooth layer, whilst the smooth layer is still tacky; or (2) using a wick type spreader consisting of a cloth wick fed by a perforated or slotted pipe on each side of the wick so that each tube feeds alternate sections of the wick, and thereby coating the base with alternate strips of matt and smooth layers. Preferably, the smooth layer is an anti-halation layer which will dissolve in alkaline developers, e.g. a layer as described in Specification 565,125, and the matt layer is similar but contains a small amount of boric acid. If applied by dusting on in powdered form, the matt layer may be polyvinyl phthalate, a rosin maleic anhydride condensation product prepared as described in Specification 355,281, [Group IV], or a glyptal resin such as that sold under the Registered Trade Mark " Abralac P."

Title: Improvements in valves or like throttling devices
Inventor: DANEL PIERRE FRANCOIS
IPC: F16K1/38
Filed: 1954-02-05
Abstract: 755,545. Interconnected valves. ETABLISSEMENTS NEYRPIC. Feb. 5, 1954, No. 3510/54. Class 135. In a valve having two annular closure members closable in succession by a single control means on to primary and secondary seats, the primary seat and its closure member are rigid and the secondary seat or its closure member resilient. The primary seat is formed on the conical surface of a male seating member and the secondary seat below the primary seat either on the conical surface or a cylindrical extension thereof. As shown, concentric sleeves 12, 18, Fig. 1, constituting the primary and secondary closure members respectively sealingly surround a discharge tube 10 connected, e.g. to a reservoir and engage in succession a conically-ended seating member 30 secured by fins 31 to the tube 10 and an elastic ring 34 secured to the member 30 in a position such that when the valve is open the ring is shielded from the flow of fluid through the valve to reduce wear on the ring. The valve is operated by a plurality of spring-loaded rods 21 secured to a flange 20 on the sleeve 18 and passing loosely through holes 23 in a flange 14 on the sleeve 12. The rods being movable by a single operating member. In closing the valve, the sleeves 12, 18 initially move together, the springs 26 being strong enough to allow this, until the sleeve 12 engages the member 30, to close the valve except for minor leakages. Thence on further closing movement of the rods 21, the springs 26 are compressed so that the sleeve 18 moves relative to the sleeve 12 and engages and compresses the elastic ring 34 to ensure a fluid-tight closure. In a modification, an elastic ring 57, Fig. 4, comprising the secondary closure member, is mounted on an annular structure 56 to which operating rods 52 are secured and a sleeve 61 comprising the primary closure member is resiliently connected to this structure by studs 65 and an elastic ring 64. As shown in Fig. 4, both closure members are closed and the ring 64 . compressed. On opening the valve, pressure on the ring 64 is first relieved whence the ring 57 moves away from the cone 44 into a shielded position behind the sleeve 61 until the ring 64 urges the structure 56 into abutment with lock-nuts 67. On further opening movement both the ring 57 and the sleeve 61 move away from the cone 44 to fully open the valve.

The subject-matter is the same as that of Specification 684,833 but the claims are directed towards the synchronising balk-teeth which, during movement of the dog-clutch sleeve Q, see Figs. 9 and 29 in the abridgement of 684,833, forward from neutral to establish free-wheeling second speed through the overruning roller clutch F, by releasing the cage of the latter to permit its rollers to engage, positively prevent such release movement of the sleeve Q whilst the forward speed of the main input shaft 83 of the gear-train in which the roller-clutch F transmits reduced drive exceeds that of the final driven member 93 of the gear-train, so that the roller clutch is only released for engagement when the input and output shafts 83, 93 of the gear train synchronise or whilst the output is overrunning the input. The synchronising thus applies to the input and output members of the gear-train and not necessarily to the parts of the roller-clutch itself, but it ensures that the roller-clutch is only released for engagement when its driven member 104 is overrunning its driving member 118, or when both those members are stationary.
