Abstract: 1,237,139. Self-seating valve. GENERAL TIRE & RUBBER CO. 23 Sept., 1968 [16 Oct., 1967], No. 45153/68. Heading F2V. A self-sealing valve comprising a cylindrical conduit 26 disposed at right angles to a cylindrical chamber 20 includes an elastomeric sleeve 52, normally of cylindrical form, deformed to provide a seal at the end 28 of the conduit 26. The pressure of incoming fluid in conduit 26 forces the sleeve 52 further to deform away from the end 28 to allow fluid access to the chamber 20. When the chamber 12 is filled to the desired pressure, the flow is stopped by the valve returning to a sealing position under the pressure of fluid in the chamber 20. The chamber 20 may be depressurized by inserting a rigid member (60) in along conduit 26 to unseat the sleeve 52. Where air is the pressurizing fluid, the sleeve 52 is made of neoprene.

Title: Film counter device for a movie camera
IPC: G03B21/44
Filed: 1975-11-11
Abstract: 1529825 Film counters NIPPON KOGAKU KK 11 Nov 1975 [15 Nov 1974] 46578/75 Heading G2A  A camera has plural counter scales, corresponding to different lengths of film, the counter moving through the whole of the particular scale which is being used, as determined by automatically set means responsive to the cartridge inserted, which has a characteristic (e.g. shape) indicative of the length of film therein. In Fig. 1, two gear-wheels 11, 12, fixed together, are mounted by a shaft 9 at the centre of a three-armed lever 8. In the position shown, gear 11 drives, via an intermediate gear 13, a gear 1b to which is fixed a counter dial 1a carrying two sets of footage scales, 0-50 and 0-200. This is the position for a standard cartridge containing 50 feet of film. During the picture-taking operation, the movement of the film is transmitted to gear 11, and hence to gear 1b, and so is shown on the dial 1 a, which turns through the full scale as the whole length of film is transported. If a large cartridge containing 200 feet of film is introduced into the camera, an additional part of the cartridge projects downwards to engage a slider 6 and push it downwards, from the Fig. 1 position to the Fig. 4 position. This pushes downwards the end 8a of lever 8 to pivot it anti-clockwise. Consequently gear 13 is retracted out of engagement with gear 1b, and gear 14 is now brought into engagement with gear 1b. Thus the film movement is now trasmitted to the counter dial via gear 14. The gear ratios are such that dial 1a now turns at a quarter of its previous speed, so that again it will turn full scale for the whole length of film, which is four times longer than in the standard cartridge. Fig. 6 shows another embodiment in which the film counter, instead of being a rotating dial as in Fig. 1, is a sliding pointer 21, whose end 21b reads against a linear scale (not shown). The pointer is moved by engagement with one of two worm rods 29 or 31, either of which can be rotated into engagement with the pointer by similar means to that described in the first embodiment.

In a socket for an electrical appliance in which spring contacts fixed at one end press the conductors of the supply wires against the insulating housing at the other end, entry of the appliance pins is arranged to increase the pressures on the conductors. As shown, the spring contact 2 is supported and located by a pair of tongues 5, which rest on shoulders in the housing, and by embossed projections 7 which engage appropriate recesses in the housing. A toothed part 10 at the other end grips the conductor against the inner surface 13 of a depending part of the housing. The pins of the appliance, e.g., a lamp, enter slots in the housing so that they are supported by it on one side and on the other bear against resilient projections 9 on the contacts to increase the grip on the conductors.
