Title: Film metering device for photographic printers
IPC: G03B1/66
Filed: 1966-04-06
Abstract: 1,147,002. Film metering device. EASTMAN KODAK CO. April 6, 1966 [April 12, 1965], No.15331/66. Heading G2A. A photographic printer has a film-metering device for driving a film strip from which prints are to be produced, comprising a film drive means, first and second pointers the location of which is adjustable so that they are respectively one and two frames away from the printing aperture, and circuit means for selectively moving the film once or twice the distance between the aperture and the first pointer depending on whether or not the image adjacent the printing aperture is printable. As shown in Fig. 1, the film 16 is transported through a printing aperture 17 by a pair of metering rollers 21 driven by a shaft 12 via gearing 24, the shaft 12 being driven by a motor 10 via a clutch 11. First pointer 28 is aligned with the trailing edge of the frame of film adjacent aperture 17 by a handle 32 which drives via a gear-wheel 41 a rack 42 which supports pointer 28 and engages a gear 43; the position of second pointer 29 is simultaneously adjusted by a gear 45 driving coupled with gear 43, the gearing being such that pointer 29 moves twice the distance that pointer 28 moves and is hence always twice the distance away from the aperture 17. The movement of the film 16 is governed by logic circuitry Fig.4 (not shown); on closing contact 33, clutch 11 is energized and brake 13 is de-energized causing the film to be driven, and a face plate 36 of a clutch 26 rotated until an abutment 44 thereon contacts a fixed stop 47 operating a switch 37 which causes clutch 11 to be de-energized and brake 13 to be energized thus terminating the movement of the film strip; the plate 13 is then returned by a spring 48 until it engages a stop 44 on gear 43 where it is held so that the rundown time of plate and hence the amount of movement of the film 16 is governed by the position of stop 44 which is dependant upon the position of pointer 28. On depressing a switch 34 instead of switch 33, a capacitor (77) causes termination of transport of the film only whilst plate 36 is being returned by spring 48 so that the film strip moves two frames. The prints are formed on a photosensitive web (38 Fig. 2 not shown), using a lamp (60), a shutter (61) and a lens (62), the web (38) being moved one frame after each exposure by rollers (39) controlled by the circuitry. The movement of the film-strip 16 on supply and takeup rollers (52), (53) is controlled by loop sensors (56), (57).

Title: Improvements in gyroscopic artificial horizon instruments for aircraft
IPC: G01C19/32
Filed: 1942-11-13
Abstract: 599,249. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. Nov. 13, 1942, No. 16084. Convention date, Nov. 13, 1941. [Class 97 (iii)] A gyroscopic artificial horizon for indicating aircraft attitude is combined with means responsive to turn of the craft for showing the virtual horizon as distinct from the real horizon and affording an indication of the correct bank during turns. The indication of the virtual horizon is effected by means of an index ring rotated in proportion to the product of the rate of turn and the linear speed of the craft, that is, in proportion to the centrifugal force of the turn. The linear speed factor may be introduced manually or automatically. As shown in Fig. 2, a housing 7 contains a gyroscopic horizon of usual form provided with an horizon bar 10, Fig. 4, read in connection with indices 40, 41 and also read by reference to a representation 44 of an aircraft on the front window 45. The indices 40, 41 are carried by an index ring 21 rotatably mounted in the bezel 38 of the window, the ring being turned in proportion to the centrifugal force of the turn being made, by a rate-of-turn gyroscope 22 whose transmitted movement to the index ring 21 is modified as described below according to the air speed of the craft. When the craft turns, the gyro 22 precesses and by means of a rod 26 and toothed sector 35, rotates the index ring 21. For correct banking, the horizon bar 10 is maintained in alignment with the indices 40, 41 on the index ring, the aircraft representation 44 being undisturbed relative to the aviator, and the usual ball bank indicator 70 remaining in a central position. The linear speed factor is introduced into the transmission by adjusting the pivotal connection 28<1> between the rod 26 and the toothed sector 35 by means of a speed knob 31. The index ring 21 is provided with angular markings 42 showing the direction and rate-of-turn (for any selected air speed) and readable against an index 43 secured to the bezel 38. An index 39 on the rotatable index ring co-operates with an index 20 on the usual masking plate 19 to show the amount of roll. In a modification, the rate-of-turn gyro is directly geared to the rotatable index ring 21 and the linear speed factor is introduced by manual variation of the tension of the centralizing spring of the rate-of-turn gyro. In a further modification, the rate-of-turn gyro transmits its movement to the index ring through a single lever, the fulcrum of which may be adjusted manually in accordance with the air speed. The rate-of-turn is indicated by a pointer attached to the gyro case. The air speed factor may be introduced by varying the speed of rotation of the rate-of-turn gyro, for example by connecting the suction outlet 8 to a venturi tube in the air stream giving a suction proportional to the air speed.

Abstract: 1,067,835. Pneumatic control means for doors having inflatable seals. SOCIETE D' ELECTRO-CHIMIE D'ELECTRO-METALLURGIE ET DES ACIERIES ELECTRIQUES D'UGINE. April 20, 1964 [April 22, 1963], No. 16216/64. Heading E2M. A pneumatic control device for at least one inflatable joint or gasket, comprises means for the direct application of the pressure of an inflatable joint or gasket as information for feeding into a logical pneumatic device and means for the direct application of the outlet pressure of this sequence to control the operation of the inflatable joint or gasket. As described, the system refers to two doors having inflatable gaskets for sealing purposes, an object of the invention being to ensure that one gasket cannot be deflated unless the other is inflated. Fig. 1 shows the position of the hydraulic system with seal G1 inflated and seal G2 deflated, dotted lines refer to pipelines at datum pressure and continuous lines to pipelines at operating pressure, 6 and 7 are the operating valves for G1 and G2 and distributors 1, 2, 3, 4 of the rocking or seesaw type (Fig. 4) constitute the control system. The distributors are as described in Specification 1,016,688. If an attampt is made to deflate G1 while G2 is still deflated by operating 6 to suit a datum pressure signal to valve 1, this has no effect for both input and output of valve 1 are at this pressure, consequently Gl remains inflated. If however G2 is now inflated by operation of valve 7 this causes the valve 3 to effect the input pressure of valve 4 to be at datum pressure and this further allows air to inflate G2 this pressure then operates valve 1 and consequently valve 2 to deflate G1. This control system may also be used for control between a gasket and the pressure inside an enclosed container.

Title: Improvements in motors with displaceable rotor
IPC: H02K7/12
Filed: 1955-06-06
Abstract: 784,442. Induction motors. DEMAGZUG GES. June 6, 1955 [June 4, 1954; March 2, 1955], No. 16255/55. Class 35. A squirrel cage motor has a conical axially movable rotor having at one end a ring 1 partially enclosed by an iron ring 2. When current flows in the ring 1, the flux produced thereby embraces the stator nearby projecting end 3 facing the rings 1, 2. Thus, during starting an additional axial force is produced on the rotor. The rotor axial force is utilized to disengage a friction brake when the motor is started. In Fig. 2, the ring 1 is replaced by a ring 5 fixed at the wide end of the conical rotor and is partly enclosed by an iron ring 6. In this arrangement, the stator projecting end 3 of Fig. 1 is left out, but owing to the shape and position of the iron ring 5, the latter is also embraced by some of the stator and rotor leakage flux. In Fig. 4, the only flux embracing the iron ring 10 is that which is diverted tangentially from the stator and rotor stray flux and, in this arrangement, the current carrying ring is merely used as a support for the iron ring 10.
