Title: Improvements relating to magnetically operated valves
Inventor: FELGATE JACK
IPC: F16K31/08
Filed: 1954-08-12
Abstract: 813,260. Fluid-pressure servomotor-control systems; valves. TRIST & CO. Ltd., R. Aug. 11, 1955 [Aug. 12, 1954], No. 23490/54. Class 135. In a valve having a driving magnet separated by a partition from a driven magnet actuating a pair of valve members each .of which cooperates with a seat formed on the end of a passage so that one valve member is seated whilst the other is unseated, the valve members are mounted substantially coaxially in a common frame connected by a mechanical linkage to the driven magnet to permit slight freedom of movement of the frame and so allow the true seating of the valve members. As shown, the driving magnet 7, Fig. 1, is connected to a float 5 responsive to water level in a boiler in a train heating system and the driven magnet 21 to a block 22 connected by a pivot-pin 23 to lugs 18 formed on the boss 16 of the casing cover 2. A frame 39, Fig. 3, mounting valve members 32, 33 controlling passages 12, 13 connected to a supply of compressed air and atmosphere respectively is pivotedly mounted on arms 28 having slotted ends receiving pivot pins 27 which are screwed up hard against the magnet 21 to secure it in the block 22. Split rings prevent the arms 28 sliding axially clear of the pins 27. A pin connecting the arms 28 together has a short mid length 31 (Fig. 2, not shown), slightly smaller than the bore in the boss 16 through which it passes to permit rocking of the arms and frame and hence true seating of the valve members. The adjacent ends of the magnets 7, 21 have like poles so that on movement of the magnet 7, the magnet 21 is repelled. On, for example, the water level in the boiler falling, the float 5 swings downwardly on its pivot-pin 4, the magnet 21 moving the frame to close the valve 32 and open the valve 33 to atmosphere to vent the space 10 above the piston of a piston-actuated boiler feed-water valve 11 so that this valve opens under the action of a spring 19 to supply water to the boiler.

Abstract: 1,138,590. Microcapsules. NATIONAL CASH REGISTER CO. 22 May, 1967 [17 June, 1966], No. 23569/67. Heading B8C. [Also in Divisions G1, G5 and H4] Capsules having sizes between 1 and 5000 microns and having a transparent wall enclosing a mesomorphic liquid material for use as a temperature indicator are made by a process which includes the addition of acid-extracted pigskin gelatine having a pH of 8 to 9 and gum arabic to distilled water at 55 C. in a Waring Blender yielding a solution of about pH 4À5, the pH of this solution being adjusted to 6À0 by addition of 20% by weight aqueous sodium hydroxide solution. The desired cholesterol derivatives which it is desired to encapsulate are then added, and these materials are emulsified in the Waring Blender to an average droplet size of 10 to 50 microns. The pH of the solution is reduced by addition of 14% by weight aqueous acetic acid until at about pH 5 single liquid walled capsules cluster to form aggregates having diameters of 25 to 100 microns. The system is chilled to below 10 C. while agitation continues. A chemical hardening agent for the gelatine is added, e.g. 25% by weight aqueous pentanediol solution, the system then being stirred for 12 hours whilst slowly returning to room temperature. The capsule walls have then become hardened and the capsules are sieved to obtain the desired capsule sizes.

Title: Means for the rotational reversal of diesel and the like engines
IPC: F01L13/00
Filed: 1933-08-24
Abstract: 429,031. Reversing; stopping; turning- gear. PAXMAN, E. P., and DAVEY, PAXMAN, & CO. (COLCHESTER), Ltd., Standard Iron Works, Colchester. Aug. 24, 1933, Nos. 23590 and 24734. [Class 7 (v)] [See also Groups XXXV and XXVIII] In a Diesel or like heavy oil engine a manual control device is arranged to operate a starter or starters to turn the engine in the required direction whilst simultaneously controlling and timing the oil fuel supply in accordance with the speed and direction of rotation required. Compressed-air motors or other devices may be used for starting the engine. As applied to a two-stroke engine, a control wheel 1 fitted with an indicator 9, 10 drives a shaft 14 through a chain 12, which shaft controls pawls 16 to operate one or other of two starting switches 18 which effect energization of one of two electric starting motors 6 according to the direction of starting required. Shaft 14 also controls links 35, 19 through eccentrics and effects rocking of two shafts 4, 21, of which the shaft 4 controls the governor loading through a lever 44 and the fuel supply through a lever 38 acting on the fuel pump spindle 39 which is also acted on by a governor-controlled lever 42. Shaft 21 controls a dog-clutch connection between the engine cam shaft 24, Fig. 3, and the fuel-pump drive shaft 28 by means of dogs 27, 26 having notched faces which can engage in either of two positions depending upon the direction in which the cam shaft is rotated by the electric starting motors thereby controlling the fuel-injection timing. Teeth 31 operated by a lever 22 from the rock shaft 21 hold the dogs in the requisite position or release them according to the position " start " or " stop " of the hand wheel 1. Speed control of the engine by adjusting fuel supply and governor loading is effected through the lever 35 from the control wheel 1 for forward and reverse rotation. Continued rotation of the wheel 1 beyond the " start " position releases the pawl connection 16 to the starting-motor switch 18 and de-energizes the motor. A plunger 47, Fig. 2, operated by engine oil pressure in a cylinder 48 operates on a notch in a wheel 49 on the shaft 14 to hold the control wheel and gear in the " stop " position when once moved thereto, until the engine has stopped rotating. The invention may be applied to a reversible four - stroke engine. The control may be arranged remote from the engine or may be operated by a servo-motor. A clutch in the main drive shaft may be arranged to be disengaged in positions of the control wheel near the " slow position on either side of the " stop " position so as to reduce the load on starting and to enable the engine to run slow with the clutch disengaged.

Title: Improvements in or relating to variable-pitch propellers
Inventor: BASEVI SIDNEY PHILIP
IPC: B64C11/38
Filed: 1950-09-29
Abstract: 691,755. Variable-pitch propellers. ROTOL, Ltd. Sept. 12, 1951. [Sept. 29, 1950] No. 23937/50. Class 114. A variable-pitch propeller has its blades adjustable, by a hydraulic jack, into a normal pitch range controllable by a speed governor, a first extended range, and a second extended range, e.g. reverse pitch, movement from one range to the other being limited by first and second stops 28, 27 respectively which are withdrawn in succession, restraint means being provided to prevent the second stop from being withdrawn until it has been engaged by the moving member of the hydraulic jack. The stops are carried by spring fingers 26, 25 respectively and are held in an outer position by an abutment 31 on a hydraulic piston 30 loaded by springs 33, 43. The normal pitch range is limited by engagement of the end 23 of the jack piston S, which is linked to the blades, with the stops 28. The latter are withdrawn by supplying hydraulic fluid to the piston 30 which moves to the right thus releasing the stops 28 whilst keeping the stops 27 operative. The jack piston may then move further to the left until it is again stopped by engagement of a shoulder 24 with the second stops 27. Movement of the piston 30 for releasing the second stops is prevented by engagement of a sleeve 42, carried by the piston, with stops 39 carried by spring fingers 40. The latter are held inwardly by a ring 38, biased by the spring 33, carried by the fingers 25 of the second stops 27. When the hydraulic pressure on the jack piston 8, which is then in engagement with the second stops, is increased beyond a given value by the direct action of the pilot, the stops 27 and the ring 38 move to the left against the spring 33 thereby releasing the stops 39. The piston 30 may then be moved by hydraulic fluid further to the right to release the second stops 27. Specifiation 672,953 is referred to in the Provisional Specification.

Abstract: 1,262,753. Web cutting apparatus. ILFORD Ltd. 12 May, 1970 [13 May, 1969], No. 24298/69. Heading B4B. An apparatus for cutting a web of material, e.g. film, while in motion comprises a rotary drum 21 having a radial slot 25 with which a cutter arm 35 is arranged to co-operate under the control of a cam 19 such that, in operation, the cutter arm will cut through a web on the drum at the slot and will descend, together with the cut edge of the web, into the slot and remain in the slot for a predetermined period. The drum 21 is mounted on a shaft 11 which is rotatable in a housing 16, a plate 18 being fixed thereto and provided with a cam track 19. The knife arm is pivotally mounted on a bracket which is secured to the drum and is oscillated relative to the drum by a cam follower 40 via gears 37, 38. In operation, perforated film is fed on to the drum and engaged by teeth 22 thereon. Rotation of the drum then causes the knife to pivot and cut through film, an enlargement (43), Fig. 4 (not shown), on the knife depressing the leading end of the film into the slot. At the moment of cutting a pair of fingers (56), Fig. 5 (not shown), are moved by means of a cam-and lever mechanism (51), (52), (54), (55) into contact with the edges of the film so as to hold the latter during continued rotation. After a certain rotation of the drum the knife rises out of the slot, the enlargement then lifts the free end of the film and guides it between a pair of spaced shoot members, the fingers then being released.
