Patent GB-135289-A (GB)
IPC: G04C3/02
Abstract: 135,289. O'Leary, W. Nov. 20, 1918. Escapements.-A clock having either gaining or losing rate stops itself and lets falls the impulse lever of an independent correct pendulum or balance. After giving the impulse, the lever puts re-starting and re-setting mechanism into action. The impulse lever 3, Fig. 3, pivoted at 4 is normally at rest with a toe 18 on the shoulder 17 of a lever 12 pivoted at 13, which in turn rests upon the periphery of a disk 7 on the arbor of the minute-wheel. Just before the expiry of the minute (the clock being fast), a notch 10 in the disk comes under the toe 18 of a lever 12, letting it drop and stop the clock by engaging the balance 8. The shoulder 17 is thus cleared from the toe 18, and the impulse lever 3 falls on the impulse pallet 1 of the independent pendulum or balance 30, Fig. 5. After giving the impulse, the lever falls farther and, with its toe 21, disengages a detent 22 from a cam 9 urged by a separate mainspring and train. The cam, acting on the arm 19 of the drop-lever 12, lifts it off the balance 8 of the clock. Also, by acting on the toe 20 of the impulse lever 3, the cam resets it on the shoulder 17. The flirt 11 prevents the drop-lever from falling back into the notch, and the clock recommences going. The clock balance 8 is provided with a set of pins 16, 24 on opposite faces, and the drop-lever 12 has two corresponding one-way fingers 15, 23. If the clock is adjusted to have a losing rate, the drop-lever 12, Fig. 4, is supplemented by a separate and overlying lever 25 which carries the fingers 15, 23. This lever is only on the balance at starting, and, after being once lifted by the reset drop-lever 12, it remains on a catch. An additional toe 27 on the impulse lever 3 advances the retarded notched disk 7 by acting on a pin 29 thereon. Electric clocks.-In the electrical clock mechanism which is described in Specification 120,685, the independent pendulum may be replaced by the balance, Fig. 5.

Title: Improvements in bearing and lubricating arrangements for spinning and twisting machine spindles
IPC: D01H7/04
Filed: 1952-05-28
Abstract: 722,840. Stud and socket fastenings. NAVARRO, F. A. May, 28 1952. No. 13671/52. Class 44. [Also in Groups XXIV and XXXIV] A spinning spindle has a casing 1, Fig. 3, to which is screwed a nut 15 for securing the casing to the machine frame, and a non- rotatable oil reservoir 14 is releasably fastened to an extension 16 of the nut by means of a ring 18 adapted in its operative position to engage balls 17 located in radial holes in the reservoir 14 with an annular groove in the nut extension 16. When it is required to remove the reservoir 14 the ring 18 is lifted to permit the balls to move radially outwards and disengage the groove. The lower edge of the ring prevents the balls from passing outwardly of the holes, and the balls are prevented from falling inwardly by reduction of the inner ends of the holes. A rotating spindle proper may be detachably mounted with respect to the casing in a similar manner.

Abstract: 166,406. Molins, W. E. May 17, 1920 Packeting cigarettes, confectionery, soap, &c. in receptacles.-Relates to apparatus for packing cigarettes, bars of chocolate, caramels, soap, &c.. into open-mouthed packets and may be used in conjunction with the. apparatus described in Specifications 13956/15 and 13957/15. Openmouthed packets 4 are contained in a magazine 1 and a filling funnel 9, formed of spring blades, enters the lowermost packet to assist in the insertion of a batch 22 of cigarettes, &c. by a pusher 20. The funnel 9 is mounted on an arm 10 rigidly connected to an arm 11 pivoted at 12 to the frame of the machine, and is normally held in the position shown in broken lines by a spring 13. An adjustable stop 14 limits the inward movement of the funnel. A pivoted tongue 15 is mounted adjacent to an opening 7 in the back 8 of the magazine, and is normally held in contact with the lowermost packet by the engagement of a roller 16 on a spring-urged arm 17 with a notch 19. In use, the movement of the cigarettes, &c. carries the funnel into the mouth of the packet, and, when the insertion is complete, causes the tongue 15 to yield and allow the passage of the packet. The filling-means 20 may be of the conveyer or reciprocating-plunger type, and may operate upon the funnel otherwise than through the movement of the cigarettes, or the funnel may be positively actuated.

Abstract: 728,142. Fluid-pressure servomotor-control systems. BRITISH MESSIER, Ltd. May 26, 1953 [May 28, 1952], No. 13602/52. Class 135. A servo-mechanism suitable for the power assistance of aircraft flying controls comprises an input lever 16 connected at 18 to a pilot's control rod 19 and pivoted about a point 17 to an output lever 11 which is connected at 14 to a flying control surface and is mounted on a fixed pivot 13. The lower end of the input lever 16 has lost-motion on the pivot 13 and is connected by a rod 20 with control means for the servo-mechanism, the axis of the pivotal connection between the rod 20 and the input lever being substantially in line with that of the pivot 13 for the output lever. As shown, the servo-mechanism is a hydraulic jack 23 whose cylinder is anchored at 31 and whose piston 65 is connected to the input lever at a point 27 on the opposite side of the pivot point 17 to the pilot's control, but substantially closer thereto. Thus " feel " is experienced by the pilot. The servomotor control-means is a loaded piston valve 45 connected through a spring-loaded ball catch 53 to the rod 20 whereby the rod may become disconnected from the valve in the event of valve seizure. A spring-loaded piston (not shown) is subject to the pressure of the hydraulic supply and connected to a rod 36 so that when pressure is available a bell-crank lever 33 is in the position shown in which a slot 34 provides room for relative movement between the upper end of the input lever and the bell-crank lever for operation of the control valve 45, but in the event of hydraulic failure the bell-crank lever is moved clockwise about the pivot 14 to cause a narrower part of the slot 34 to lock the input and output levers together for direct manual operation of the flying control. The hydraulic failure also enables a valve (not shown) interconnecting the two ends of the servomotor to be opened.

Abstract: A thin flexible sheet material comprises one or more layers of spaced unwoven, substantially parallel filaments of durable material (i.e. material which is insoluble and not subject to swelling in water and organic solvents, e.g. metals and thermosetting plastics), with the spaces between the filaments blocked by a substantially imperforate layer of durable material. A stencil blank comprises a substantially imperforate sheet, to or in one or both surfaces of which is or are secured or embedded a layer or layers comprising a series of spaced parallel unwoven filaments of a different material from that of the sheet, while if two layers of filaments are used, the filaments in one layer are at right angles to those in the other.  A layer of filaments may be secured between two sheets.  The filaments may be secured to the sheet by welding or embedded therein by pressing. Alternatively, one or two layers of filaments may be sprayed from both sides with molten metal, and the assembly subjected to heat and pressure to flatten the sheet and increase the density, the surfaces being smoothed by grinding, polishing or machining.  For example, stainless steel wires 0.02 inch apart and 0.002 inch in diameter may be pressed into a sheet of aluminium foil 0.005 inch thick.  If two layers of wires are used, the foil may be 0.005-0.01 inch thick.ALSO:A thin flexible sheet material comprises one or more layers of spaced unwoven, substantially parallel filaments of durable material (i.e. material which is insoluble and not subject to swelling in water and organic solvents, e.g. metals and thermosetting plastics), with the spaces between the filaments blocked by a substantially imperforate layer of durable material.
