Title: Mechanical improvements in cinematograph projection
IPC: G03B1/42
Filed: 1923-11-29
Abstract: 230,384. Taylor, A., and Taylor, H. D. Nov. 29, 1923. Kinematograph apparatus.-In continuous-feed projectors the construction of the sprockets is modified and differential gearing is provided to ensure the correct placing of the film picture in the gate irrespective of variations in the correct spacing of the sprocket holes. The modifications are described with reference to the system of projection set out in Specification 230,152. The sprockets D<1>, D<2>, Fig. 1, are in three parts, the end portions carrying the teeth being constructed so as to permit axial movement under the pressure of a spring surrounding a sleeve in one with the end-piece 5 and acting against the end of a similar sleeve on the end piece 6. The drum portion of the sprocket is mounted loosely on the sleeve extensions of the end pieces 5, 6. The sprocket teeth are formed so that they permit the film to bear on the roller 7. Loose rollers 8 of the same diameter as the roller 7 are placed outside the pieces 5, 6 as shown, and the film is pressed against these rollers by spring-controlled jockey rollers J. The differential gearing by which the film picture is raised or lowered comprises a toothed wheel 10 rotating freely on a sleeve on the driving pinion 9 and carrying a toothed pinion 11 in gear with wheels 12, 13, one of which has one more tooth on its periphery than the other. To alter the position of the picture a toothed detent r is brought for a short time into contact with the wheel 10, causing one of the wheels 12, 13 to rotate faster than the other, and thus to advance or retard the film in the gate. In a modified form of sprocket the sprocket is made in radial sections which may be pressed outward against the action of a spring by means of sliding coned sleeves on the sprocket spindle. This movement enables the diameter of the sprocket to be varied in accordance with alterations in the pitch of the sprocket holes. The sliding sleeves are moved by a screwed head in one with them held in position by a spring catch. The setting of the screwed head is determined by a film gauge, Fig. 7, provided with two fixed teeth t at one end and a tooth T on a lever L at the other end. The indication of the scale A gives the setting of the screwed head of the expansible sprocket. A further modification of the sprocket, Fig. 5, consists in omitting every other tooth of the sprocket and fitting the jockey wheels with the teeth and recesses as shown. The movable portion of the gate is pressed against the fixed portion of a balanced lever, Fig. 1<b>, and the opposing surfaces of the gate may be curved concave to the lens to a radius of four times the focal length of the lens, which is preferably that described in Specification 210,705. The gate may comprise surfaces of glass or quartz. Specifications 155,793 and 197,707 also are referred to.

Title: Electrical Measuring Apparatus
Inventor: NOTON GEORGE JOHN
IPC: B65H43/00
Filed: 1967-05-24
Abstract: 1,158,455. Selective signalling systems. ENGLISH ELECTRIC CO. Ltd. 21 May, 1968 [24 May, 1967], No.24261/67. Heading G4H. As strip is wound on to or from a reel 11, pulses are generated, 13, for equal increments of rotation, a counter 14 defines timing intervals which vary with the diameter of the coil on reel 11, a counter 18 is controlled by the timing signals to count pulses generated at 12 representing increments of length of strip fed by rollers 10 to provide a signal representing the depth of the coil, and a divider 31 divides the depth of coil signal by a signal representing the strip thickness. The resulting signal is proportional to the length of material on reel 11 and may be used to slow down the extraction of strip so that reel 11 stops when there is substantially no more strip left on it. Half-way through a cycle of counter 14, counter 18 is read out and reversed, the count entered in register 20 being proportional to the average coil thickness during the half measurement cycle. During the second half-cycle, counter 18 counts down, and the count remaining at the end of the cycle, which is proportional to the difference between the average coil depths during the two half-cycles and hence to the strip thickness, is entered in register 21. Alternatively, a direct measurement of strip thickness may be made. After conversion to an analogue signal 25, and correction at 27 for variation in coil depth during the second half cycle, the coil depth signal 26 is smoothed by the addition of a saw-tooth which is scaled by the thickness signal and is derived from counter 14. The output of divider 31 is passed to square root circuit 32 and inhibit circuit 34 which prevents application of the signal to the control circuit until it drops below a preset level.

Title: Improvements in or relating to locks
IPC: E05B27/00
Filed: 1947-09-03
Abstract: 627,202. Barrel locks. SILVA, J. DO C. D. DA: Sept. 3, 1947, No. 24276. [Class 44] A barrel lock comprises a cylinder 4 rotatable inside a casing 1 and carrying an upper and lower series of radial tumblers 2, 3 adapted in the locked position to engage bores in the casing and in the unlocked position to'be wholly contained in the cylinder. Each upper tumbler 2 is connected to the corresponding lower tumbler 3 by a lever 6 accommodated in a peripheral slot 5 in the cylinder and connected by a spring arm 12 to an axially displaceable spring loaded plunger 7. A projection 9 of non-round section engages in a similarly shaped recess in the base of a key 10 which is inserted to release the lock. Downward movement of the plunger under the action of the key tilts the levers to withdraw the upper tumblers 2 from the bores in the casing and engages their inner ends in recesses 22 in a cylindrical skirt of the key. The abutment between the ends of the tumblers and the bottoms of the recesses 22 of a correct key checks the movement of all tumblers at a point where their outer ends lie in the surface of separation between the cylinder 4 and the casing 1. After the key has been inserted to release the tumblers it is turned to rotate the cylinder 4 which may be connected to operate the mechanism of a lock or padlock. Each upper tumbler 2 has a side rib 16a received in a corresponding groove in the bore in the casing. The groove of each bore is set at a different angle so that the lock can only be relocked when the cylinder is returned to its initial position.

Title: Improvements in or relating to printing and like machines
Inventor: ARMELIN EDOUARD ROGER
IPC: B41F1/14
Filed: 1953-09-02
Abstract: 743,296. Cutting machines. CHAMBON, Ltd. Dec. 1, 1954 [Sept. 2, 1953], No. 24317/53. Class 31 (1). [Also in Group XVI] In a cutting machine, e.g. for cutting-out' carton blanks, of the kind in which sheet material is pressed against a forme 14 by means of a rocking impression table 2 having a substantially cylindrical surface 3 which rolls over the face of the forme, the impression table is pivotally mounted, at a point 5 which lies between the surface 3 and the axis of curvature of that surface, on a lever 6 fixed to a shaft 7 which is rocked to cause the impression surface to roll over the face of the forme 14. The sides of the table 2 carry rollers 9, 10 adapted to run against guide members 11, 12 shaped to follow the paths of the rollers during the rolling motion of the table. The forme 14 is mounted on a bed 1 which is moved into and out of operative position by means of toggle levers arranged in pairs 15, 19 and 16, 20 on each side which are loaded by springs 28, 31, to urge the bed down into the operative position. In this position the toggle levers are aligned so as to resist the pressure exerted by the impression table. The lever 20 on spindle 22 and a corresponding lever on the other side of spindle 21 carry rollers 23 which co-operate with cams 24 on a shaft 25 to deflect the toggle levers and raise the forme bed as shown. Rubber buffers 34, Fig. 2, are provided mounted on brackets 35 attached to the main frame 13 for compressive engagement by flange members 33 on the bed as it comes into the operative position. This ensures that any slack in the toggle levers will be taken up before the pressure is applied by the impression table. The shaft 25 is driven from a main drive shaft through worm and spur gearing. A crank on shaft 25 is connected to an arm on shaft 7 so that as shaft 25 rotates shaft 7 is rocked. The arrangement is such that the forme bed comes into operative position immediately before the impression table begins to roll against the forme and is lifted as soon as the rolling operation is completed. The web or sheets 48 being treated are then moved forward for the next operation.

The rotor of the dynamo shown comprises a housing 5 carrying two pistons coacting with a swash-plate assembly 10, 11, 12 mounted on the stator. The pistons are associated with cylinders coupled alternatively, as the motor revolves, to high and low pressure fluid channels in the stationary block 7, the channels being fed from the pressurised fluid system of the vehicle. The speed may be regulated by controlling the fluid pressure, or, as in Fig. 2 (not shown), by varying the swash-plate angle by means of a further piston operated from the fluid system of the car.
Patent GB-243564-A (GB)
Abstract: 243,564. Fairweather, H. G. C., (Whittemore, Hulbert, Whittemore, & Belknap). Jan. 19, 1925. Cleaning, fluid-pressure processes for.-A boiler cleaner in which steam &c. is discharged through a blower has provision made for automatically preventing the closure af the steam entry valve during a predetermined interval. In the device shown in Figs. 2 and 3, the valve 2 is mounted on a worm shaft which, when rotated from the position shown in Fig. 2, moves until the under face of the worm 5 engages the casing 7. A spur-wheel 13 is held stationary by a lever 8 engaging both the worm shaft and the gear-wheel, a notch 12 being provided on the gear-wheel for this purpose. The movement of the shaft disengages lever 8 from spur-wheel 13 so that continued rotation of the worm shaft rotates spur-wheel 13 and so rotates a blower 1. Outside the casing 7 is mounted a control disc 15 moving with the 'blower and carrying a secondary disc 21 which operates to stop the blower from rotating back far enough for lever 8 to re-engages with notch 12 until a predetermined number of oscillations of the blower has been executed, movement in one direction being stopped by the lever 8 engaging a pin 14<1> in the other direction by lever 18 engaging an abrupt shoulder 19 on disc 15. As shown in Fig. 3, each oscillation of the blower will cause disc 21 to rotate through an angle corresponding to one tooth by the engagement of lever 18 with the tooth, the arrangement being such that once in each rotation of disc 21, lever 18 is prevented from engaging shoulder 19 by the interposition of part 23, so that the rotation of the blower can then be continued until lever 8 engages notch 12 and immobilizes the gear-wheel 13 and blower so that continued rotation of the worm-shaft closes the valve 2. In the modification shown in Figs. 5 and 18, a lever 33 engages a notch 31 on a disc 27 fixed to a gear-wheel 6, a second disc 29 being secured frictionally but rotatably to disc 27 so that oscillation of the blower and gear-wheel 6 causes lever 33 to advance disc 29 by one tooth per oscillation, the lever 33 being held out of the notch 31 by the shallow recesses 36, but being allowed to enter the notch 31 to stop the mechanism when notches 35 register with notch 31. In the device shown in Fig. 9, clock-wise rotation of the worm disengages the lever 46 and rotates discs 41, 43 clockwise until a shoulder 51 on the disc 43 engages the nose 45 of the lever 46 when disc 43 is rotated until stopped by a stop 48. On reversal the nose 45 is prevented from entering notch 44 until disc 43 is moved back into the position defined by stop 47. Movement through an arc greater than 360‹ is thus provided for.
