Filed: 1933-03-21
Abstract: 415,177. Optical sound - recording apparatus. DALL, H. E., 186, Dunstable Road, Luton. March 21, 1933, No. 8479. [Class 40 (ii).] In optical sound-recording apparatus employing a sound-modulated glow lamp 4 the light is concentrated in a fine line on the film 5 by a very small cylindrical lens 7 having a focal length not greater than twelve times the width of the image produced on the film, the lens being mounted in a casing 3 which also holds in fixed or adjustable relation to the lens a diaphragm 2. This has formed in it a rectangular aperture which is narrower than the source of light and is directly illuminated by it. The interior of the casing 3 is preferably ridged and blackened to prevent internal reflection. The lens is held in a slotlike recess in a holder 8, Fig. 3, with its axis transverse to the film. Using a system in accordance with the invention, the ratio of the brilliance of the image to the linear spread of light due to aberrations of the lens is a practical maximum. A suitable focal length is about ten times the width of the image, which may be À001". In a modification, the rectangular aperture is formed between two spring strips, the position of which may be adjusted by means of a nut, co-operating with a scale.

Title: Improvements in methods and means for the production of smoke screens and artificial fog
IPC: F41H9/06
Filed: 1944-05-05
Abstract: 877,554. Smoke screens. DIGHT, S. R., and SAMBROOK, K. H. Aug. 24, 1945 [May 5, 1944], No. 8539/44. Class 119. Apparatus for producing a smoke screen comprises a steam jet 67 adapted to draw hot gas from a furnace 32, a supply of oil vapourized by the mixture of steam and furnace gases, and means for discharging the final mixture from the funnel F of a ship, so that the oil vapour condenses to form smoke. When steam is admitted to the jet 67 it is also admitted to a cylinder 47 to raise a damper 10 and the hot gases are drawn into the throat tube 22, oil being injected at 70. The oil control valve may be interlocked to prevent premature admission of oil and to ensure that the oil supply is cut off before the steam. The nozzle from which the smoke is discharged is preferably cup-shaped to produce turbulence, Fig. 7, (not shown), so that the heavier oil fractions are discharged with the rest.

Title: Improvements in or relating to gas-turbine engines
Inventor: BASFORD KENNETH ARNOLD
IPC: F02K3/00
Filed: 1960-03-10
Abstract: 924,853. Gas turbine plant. ROLLS-ROYCE Ltd. March 8, 1961 [March 10, 1960], No. 8568/60. Class 110 (3). A control mechanism for a gas turbine engine comprising a manual level connected by an extensive manual linkage to a fuel control member to permit setting of the member, has means to restrain movement of the fuel control member from its set position but permit setting of the member by the manual lever, the manual lever being free for movement to compensate for expansion and contraction of the linkage. A manual lever 10, located in the aircraft cockpit, is connected by an extensive mechanical linkage 11 to a fuel control member 12 mounted on an engine of the aircraft. Thus, if the lever 10 is held fixed, the member 12 will alter in position on expansion and contraction of the linkage 11. To avoid this, the lever 10 is left free and means are provided to restrain movement of the member 12 so that the expansion and contraction of the linkage is accommodated by movement of the lever 10. As shown, an electrically operated brake 13 is operative on a lever 14 forming part of the linkage close to the member 12. The position of the lever 14 and fuel control member 12 is indicated by a synchro-device 17 feeding an indicator 16. The member 12 is set by reference to the indicator. The brake 13 is disengaged by closing a manual switch 15. The restraining torque applied by the brake 13 is limited so that the pilot can overcome it when setting the member 12 by the lever 10. An electrically operated actuator 18 and electrically operated clutch 19 may be energized by closing the switch 15. This causes the actuator to operate the fuel control member 12. In a modification, the actuator 18 is controlled by a thermocouple located in the turbine of the engine and the control is rendered operative over a particular speed range by a tachometer generator. The lever 10 may also be used to control a feathering lever and a shut-off cock in the engine fuel system. These two operations and the setting of the fuel control member 12 are effected in separate ranges of movement of the lever 10. This may be done by a mechanism as described in Specification 901,888. In a further modification, a friction or electrically operated brake is employed and the electrically operated actuator 18 clutch 19 omitted.

Filed: 1947-03-31
Abstract: 638,751. Weighing-apparatus. THORNTON, A. A. (Palmer, Inc., F. D.). March 31, 1947, No. 8647. [Class 143] [Also in Group XXXV] A weight controlled measuring device of the kind in which the volume of an adjustable capacity vessel, intermittently delivering material to a packaging machine, is varied by the variation in weight of selected filled packets from a predetermined standard, is characterized in that a timing means ensures that a time lag will occur between depositing the packet on the scale and the operative connection of the scale and the volume adjusting mechanism, and that a second timing means controlled by the degree of movement of the scale from a predetermined setting causes the adjusting mechanism to operate for varying times. The volume of a measuring chamber, constituted by the space enclosed by tubular members 12, 13, Fig. 1, may be varied by movement of the member 12, which is rigid with a hopper 1, by rotation of a motor driven nut 4 co-operating with a threaded member 3 secured to said hopper. The motor 9, Fig. 2, is rotated in either direction for a time, controlled by a timer 50, after contact has been made between any one of a series of segments 30, 31 on a commutator 32 and a movable finger 29 carried by a scale 27 on to which scale selected cartons 18 are pushed by a member 22, the time and direction of rotation of the motor 9 depending upon which segment is contacted by the finger 29. The commutator 32 is swung into a position where it may be contacted by the finger 29, after the finger has had time to settle, by the attraction of an armature 35 towards a solenoid 36 which is energised through a delayed action timer 37 when a switch 38 is closed by the pushing member 22. To prevent spilling the spout 17 is arranged to extend well into the package 18 and it is removed therefrom at the completion of each filling operation by a member 20 which is driven in timed relationship with other parts of the apparatus.

Title: Flying hot saw
IPC: B23D45/18
Filed: 1962-03-07
Abstract: 925,972. Synchronous movements. BLAW-KNOX CO. March 7, 1962 [April 27, 1961], No. 8757/62. Class 40 (3). [Also in Group XXIII] In a flying saw for severing lengths from continuously-produced pipe or rod P, the speed of the pipe is measured by a roller 40 driving a synchro 54 and the speed of a shaft 21 by which the saw and work are fed towards each other intermittently is measured by a synchro transformer 56; any change in the relationship of the two speeds results in an output from the synchro transformer which controls a differential 61 to restore the relationship. The means for moving the saw and deflecting the pipe to cause a cut to be made are driven in synchronism by a shaft 23 and the mill producing the pipe is driven from a motor 14 through gearing 15, 16 and a shaft 19 coupled to the gearing 15 drives the shaft 23 through a differential 20. shaft 21 and infinitely-variable gearing 22. The speed of the shaft 21 is preferably arranged to be slightly less than that required to keep the saw in step with the pipe and additional revolutions are fed into the differential 20 by a shaft 62 coupled to the differential 61, which is powered by a motor 65. The output of the synchro transformer 56 passes through an amplifier 60 and controls the field excitation of two D.C. motors 66, 67 to vary the speed of the shaft 62 up or down. The shaft 19 could be driven by a separate motor operating at constant speed or electrically synchronized with the mill motor.

Filed: 1938-03-24
Abstract: 496,367. Sewing - machines. SINGER MANUFACTURING CO. March 24, 1938, No. 9010. Convention date, Oct. 12, 1937. [Class 112] A take-up for sewing- machines comprises a plurality of cyclicallyoperable take-up elements travelling in circular paths at different frequencies about spaced axes. In the arrangement shown, the needledriving shaft 14 carries at its end a concentric disc 42 to which a similar disc 44 is fixed by two studs 46, and a shaft 19 parallel to the shaft 14 has a disc 36 fixed to its end by a pair of studs 35, 37 and a countersunk screw 34, and a ring 39 fixed to the disc 36 by a pair of studs 40 ; the discs 42, 44 and the disc and ring 36, 39 are spaced sufficiently to permit the thread to pass between them and are surrounded by a guard member 63, which is fixed to the machine head and provided with a thread slot 65 to facilitate threading. The shaft 19 and the loop-taker shaft 21 are driven from the shaft 14 at twice the speed of the latter by a belt 23. The thread passes through a post 47 and ironing guide 48 to an adjustable tension device 49, then over a check-spring 50, under a guide 51 and over the studs 40, 46 to guides 52 and the needle ; the studs 35, 37 also engage the thread as well as, or instead of, the studs 40 during parts of the cycle. In order to prevent entanglement of the thread in the take-up parts if it should break, the disc 36 is formed with a shallow groove 66 into which the bent end of a fixed finger 67 projects to catch and break any thread becoming wound on the take-up. The thread tension is reduced when the presser-foot is lifted, by means of a cam member 55 carried on the presser-bar to engage the spindle 56 of the tension device 49 and also by reason of the fact that the thread-guide 51 is carried on the presser-bar. The presser-bar is forced against the work by a leaf-spring 57 resting on a screw 58 and stressed by a screw 59, and is lifted by the usual lever 60. The form and number of the threadengaging members 40, 46, their distances from their axes of rotation, and their frequencies of operation, and also the relative positions of the axes of rotation and the thread-guides, may be varied to suit the operation to the requirements of the loop-taker.
