Title: Improvements in or relating to means for winding films or strips in kinematograph apparatus
IPC: G03B21/43
Filed: 1927-08-06
Abstract: 305,550. Oehmichen, E. Aug. 6, 1927. Kinematograph apparatus.-The tension of the film is regulated by a roller which is engaged by the film and controls by its movements in one direction the driving connection to a film spool, and bv its movements in the other direction a brake retarding the spool. As shown in Fig. 1, the spool 4 is driven through a differential gear the planet pinions of which are carried by a member provided with a brake drum 5. A brake drum is also secured to the shaft carrying the spool, and brake bands 8, 9, respectively engaging the drums, are operatively connected to a roller 3 in a film loop 1. Enlargement of the loop tightens the engagement of the band 8 on its drum and causes the speed of the spool to be increased, the band 9 being slackened. Reduction of the loop reverses the action of the bands 8, 9, and the spool is braked. Modifications of the differential mechanism, and means whereby the roller controls the circuits of electromagnets operating on the bands 8, 9, are described in the Specification. Fig. 3 shows a. construction in which a clutch plate 15, slidable on and turning with the shaft carrying the spool 4, is moved by the roller to engage alternatively a driven plate 18 or a braking surface 19. In a further modification, Fig. 7, the roller 3 moves an arm 38 about a pivot 43 so as to cause either a driving wheel 39 or a brake member 42 to engage a plate 41 rotating with the spool 4. Fig. 8 shows an electric motor 32 driving the spool 4, the circuit of its armature being energized when a pivoted arm carrying the roller 3 engages a contact 34, and being short-circuited, so that a braking action is produced when the arm engages a contact 33.

Title: Improvements in and relating to the manufacture of mono- and dimethyl formamides
IPC: C07C233/00
Filed: 1939-07-19
Abstract: 532,258. Mono- and dimethyl formamides. TYERMAN, W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 19, 1939, No. 21015. Drawings to Specification. [Class 2 (iii)] Mono- and di-methyl formamides are made from a mixture containing mono-, di- and trimethylamines by heating the mixture with methyl formate in an amount less than that stoichiometrically equivalent to the mono- and di-methylamines. The invention is particularly applicable to the mixture of methylamines and residual ammonia obtained by reacting ammonia with methanol. The mixture is treated with methyl formate in amount insufficient to react with all the mono- and di-methylamines, and the resulting mono- and di-methyl formamides are separated out by cooling, while the unchanged methylamines and ammonia may be returned to the first stage of the process to reduce the formation of trimethylamine in this stage. An example and diagrammatic lay-out of plant is given. The process may be used as a step in the preparation of pure mono- and dimethylamines from mixtures of methylamines, the formamides being separated by distillation and converted into the pure methylamines by hydrolysis.

IPC: F15B15/12
Filed: 1952-08-21
Abstract: 729,154. Rotary engines. ROLLS-ROYCE, Ltd. Aug. 20, 1953 [Aug. 21, 1952], No. 21066/52. Class 110 (2). [Also in Group XXIX] A fluid - operated rotary servomotor device comprises a casing 10, 12, 13 having a sun member 14 therein which is provided with three angularlystaggered segmental gears 15, 16, 17 respectively adapted to mesh'with three planet-wheels 38, 37, 36 of different size; the member 10 constituting an annular gear 11. The sun member has a central bore 21 and a side bore 22 having a gap 26 with which two opposed ducts 27, 28 communicate. An arm 23 is journalled within the bore 21 and has a flange 25 which projects into the gap 26. The gap 26. and the bore 22 are connected to a duct 29 which communicates with a space 41 between the gears 37, 38. Pressure fluid is fed to a space 39 by a pump, to the inlet of which the space 41 is connected; the space 40 between the pinions 36, 38 being supplied through the duct 28 under the control of the arm 23. The sum of the radii of the gears 15, 17 is twice that of the gear 16 so that the sun member will tend to stabilize in the position in which the pressure within the space 40 is half that within the space 39. The arm 23 may be rotated by a shaft 32; independently of the sun member; the latter member having an output drive pinion 20.

Title: Flow control valves
Inventor: POWELL KENNETH STANLEY
IPC: F16K31/36
Filed: 1964-05-21
Abstract: 1, 082, 947. Fluid-pressure servomotor systems. BRISTOL SIDDELEY ENGINES Ltd. Aug. 18, 1965 [May 21, 1964], No.21081/64. Heading G3P. [Also in Divisions F1 and F2] The supply to a turbine 10 driving a pump 11 is controlled by a flap 20 pivoted at 18 and having an extension 21 defining a chamber 25 the pressure in which is controlled by a pilot valve 26. When the pilot valve is closed, pressure is equalized across the extension via a clearance 23 around the periphery thereof, and the flap is moved to the open position by flow in the duct 12. When the pump output pressure reaches a predetermined value, it lifts ball 29 and acts on a bellows 28 to open the pilot valve, thereby reducing the pressure in chamber 25 and causing the extension to move the flap to restrict flow. The flap and extension are mass balanced but the latter is larger in area to provide aerodynamic unbalance. In Fig. 2 (not shown), the flap is upstream of its pivot point and the extension is downstream thereof. When the pilot valve is closed, the build up of pressure in chamber (25), via leakage path (35), opens the valve. To prevent shocks, an eccentric (18a) on the flap hinge progressively throttles path (35) as the valve opens. In Fig. 3 (not shown), both the flap and its extension are downstream of the pivot point, counterbalance being provided by a weighted lever (41). When the pilot valve is open, pressure in chamber (25) closes the valve. A space (42) serves to damp movement of the flap. In Fig. 3A (not shown), space (70) communicates via bore (74) with the downstream side of the flap and a space (76) is controlled by a pilot valve (82) communicating with a region of low-pressure. When the pilot valve is open, the pressure difference across extension (86) closes the valve. In Figs. 4 and 5, a pair of flaps 54a, 54b are pivoted at 53 and may be balanced by respective weighted levers. These flaps are connected at 55, 55a to further flaps 56a, 56b the free ends of which are guided in slots 58. Pilot valves 61, 64 within the chamber 60 defined by the flaps serve to vary the pressure in that chamber and are operable by any desired control device. When the pilot valves are closed, the pressure in the chamber exceeds that the fluid-flow around the flaps and the latter are thus moved to restrict flow. The pivot may lie on the wall of the duct, in which case one pair of flaps are omitted. Direct feedback may be provided by arranging for closure members carried by the flaps to co-operate with variable pilot valve holes 63, 64. Such an arrangement could be used as a variable geometry air intake or jet propulsion nozzle, the pilot valves being controlled in response to Mach number or the pressure ratio between selected points in the controlled flow. The leading flap 56 would constitute a compression ramp or multiple shock wave generating system, and the trailing flap may be convexly curved to act as a subsonic diffuser.

Abstract: 567,459. Current detectors. SANGAMO WESTON, Ltd., LOVEGROVE, H. J., and McBRIDE, M. G. May 17, 1944, No. 21090. Divided out of 567,435. [Class 37] A ratiometer is provided with means responsive to the current through the ratiometer coils for indicating the presence of such current. A magnet 60 of low remanence is mounted in close proximity to one pole of the magnet 11 of a ratiometer, such as that described in Specification 567,435, and has coils 61 connected in series with the ratiometer coils. A small permanent magnet 66 carrying a pointer 67 is pivoted so as to be in the field of electromagnet 60 and in the leakage field from magnet 11. When the instrument is not energized, the field of magnet 60 is negligible and the magnet 66 sets symmetrically between the poles of magnet 11. When the ratiometer is passing current, coils 61 are energized and magnet 66 is deflected by the overriding field of magnet 60 and the presence of current is indicated by the pointer 67.
