Title: Photographic film pack
IPC: G03B19/04
Filed: 1971-05-06
Abstract: 1344282 Film cartridges EASTMAN KODAK CO 6 May 1971 [8 May 1970] 13444/71 Heading G2A A roll-film cartridge, in which film is wound past an exposure aperture on to a take-up spool, has an additional metering strip wound on to a further spool connected to the take-up spool, the strip passing through a slot to the outside of the camera, so that pulling on the strip causes the take-up spool to rotate and wind on the film. In the form shown in Fig. 1, the film 18 winds across from a supply spool 24 to a take-up spool 30 over guide-bars 26, 28. A metering strip 42 is wound on an axle 38, which is connected with spool 30 by gears 36, 34. The guide bars and the axles of the various spools are supported in cut-outs 22a-e in a casing 10. Strip 42 passes through a slot 44 to the exterior of the camera, and when pulled in the direction of the arrow causes axle 38 to rotate, hence driving the windup spool 30. Strip 42 may be formed as a series of separate strips linked together, as by a tongue 72 on one strip hooked through a hole 74 in the next. Thus the strip may be used as a metering device, and the lengths of the separate strips may gradually decrease to compensate for the increasing diameter of the take-up spool. Fig. 2 (not shown) shows an alternative metering arrangement in which pairs of lines (50) marked on strip 42 converge to a point, indicating the transport required. Fig.4 (not shown) is an alternative arrangement in which the metering strip is wound round a spool sharing a common axle with the film take-up spool. The invention is intended for use in cameras which do not normally have means for advancing film from a supply to a take-up spool, e.g. self-processing cameras.

Title: Improvements relating to speedometers
IPC: G01P1/08
Filed: 1929-05-01
Abstract: 334,545. Arnold, C., (Dual Speedometer Co.). May 1, 1929. Index hands and pointers; indicating maximum movements.-In a speedometer the indicating needle, which pushes the maximum indicating needle locked by a ratchet and pawl, but released by a push, before it, may be optionally locked to indicate an instantaneous speed, or two normally indicating hands, one of which may be locked to show the speed at any instant, may be employed, the locking being accomplished by local or remote control. A maximum hand 20, free on spindle 12, has a lug 21 to engage the normally indicating pointer 13 and is retained in maximum position by a ratchet 24 and pawl 23. Fig. 1, the pawl releasing the hand 20, which flies back to zero under the action of the spring 22, when the push 29 is pressed to rotate the bell crank lever 25; or, in a modification, an arm of the lever 25 may be the pawl. Rotation by an external thumb screw of the stem 16 and its eccentric pin 15 raises the collar 14 fixed to the spindle 9, thus unmeshing the gears 10, 11 and causing the normally indicating hand 13 to become fixed at a position corresponding to a certain speed. A spring 19 pressing on spindle 16 keeps it in its respective positions, while the spring 18 tends to mesh again the wheels 10, 11. In a modification, Fig. 10, the indicating hand 13<1> fixed to a collar 38 free on the spindle 12<1>, the speed of which is required, meshes with the hub 35 by a projection 37 fitting into a hole in the hub, and when reading pushes the lug 21<1> and hand 20<1> before it, as before, for the maximum reading. To fix the needles 13' at any instant the hand 49 is rotated. Rising on the cam 50 it lifts the stem 46, the springs 47 and its arm 40 which is forked around the collar 38, thus lifting the collar and the hand 13<1> out of mesh with the driving hub 35. In another modification, the spindle 12<11>, Fig. 13. directly actuates the index hand 13<11>, which as before operates the maximum hand 20". An extra index hand 59 integral with a collar 38' free on spindle, 12<11> meshes with it by means of a projection fitting into the spindle hub as in the previous modification, and is unmeshed to indicate a speed by rotating the spindle 62, the cam 61 at its end raising the spring 40<1> and the fork 39<1> which lifts the collar 38<1>. The stem 62 may be operated bv a thumb screw lever 63 attached to its end externally or said lever 63 may be connected to a " Bowden " wire and operated remotely by a lever or foot pedal.

Abstract: 832,559. Vehicle power steering. BURMAN & SONS Ltd., and BRIGGS, W. H. April 17, 1958 [May 1, 1957; July 16, 1957], Nos. 13832/57 and 22468/57. Class 79(5) A vehicle power steering mechanism comprises a cylinder 3, an annular piston 7 slidable in the cylinder, a trunk 8 extending from one side of the piston, a member 9 in screw threaded or equivalent connection with the trunk and having a hollow cylindrical extension 11 forming a valve sleeve, an angularly movable control valve 15 within the sleeve and secured to a driver operable spindle 16, a rocker shaft 36 to transmit steering movements to the road wheels of the vehicle, and a radial arm 38 on the shaft 36 in engagement with the trunk 8, the valve being adapted to control ports in the sleeve whereby liquid can be directed to either end of the cylinder. A spring-loaded plunger 17 has a V-shaped recess to hold a ball in engagement with a similar recess in the sleeve 11 when the valve 15 is in neutral position in which the fluid flows idly from an inlet 4a to an outlet 33. The inlet 4a leads to a bore 25 connected by radial ports 26, 31, grooves 22, 27, ports 12. 13 in the sleeve 11, and grooves 23, 28 with the left-hand end of the valve 15 and hence the outlet 33. On moving the valve 15 anti-clockwise, fluid flows through ports 31, 13 and 34 to move the piston 7 to the left, the displaced liquid entering the port 12 and passing along the groove 23 to the outlet 33. Clockwise movement causes fluid to flow through ports 26 and 12 to the left-hand side of the piston and the displaced fluid to flow through the port 13 and the groove 28 to the outlet 33. In the event of failure of the hydraulic system, the member 9 may be operated direct from the spindle 16 by taking up lost motion between teeth on the sleeve 11 and notches in a collar 20 on the valve 15. Figs. 7 and 8 show an alternative constructon in which the positions of the inlet 34 and outlet 33 are reversed. On turning the valve anti-clockwise, liquid flows from the inlet 34 through groove 23, port 12 and passage 47 to move the piston 7 to the right, the displaced liquid flowing through port 13, passage 31 and bores 25 and 44 to the outlet. The valve 15 may be of similar construction to that shown in Fig. 1. In either of the alternative constructions, an additional groove may be formed in one side of the valve so that the fluid exerts a lateral force to reduce frictional resistance in the event of undesirable lateral pressure being applied to the valve. A spring 48 and a ball held between oblique holes of larger diameter than itself in the sleeve 11 and the valve locate the latter in its neutral position.
