Title: Strainer
IPC: B01D33/073
Filed: 1964-06-16
Abstract: Liquid entering at (9), Fig. 1 (not shown), is filtered inwards through strainer elements (13) on a vertical drum (11) rotated by a motor (53) mounted above the housing (2), or by hand at (51a). Most of the filtrate flows downwards through an opening in a ring (8) forming part of a fixed partition structure (7); the open lower end of the drum has close contact with the inside of the ring (8); filtrate is discharged at (10).  The remaining filtrate flows outwards through those strainer elements which at any instant are opposite a slot (16) in a fixed vertical shoe (14) making close contact with drum (11); such filtrate, with residues, is discharged at (17).  Two diametrically-opposite shoes instead of one may be provided, Fig. 4 (not shown).  The clearance between drum (11) and ring (8) may be adjusted by raising or lowering the drum shaft (21) in a combined thrust and radial bearing (32 to 34), this being done by rotating a nut (40) threaded on shaft (21) above the bearing, and then bending up a portion of a locking ring (41) (beneath the nut) to engage a peripheral slot in the nut 40. (The locking ring may only slide on shaft (21)).  When this has been done, further vertical movement of shaft (21) may be prevented by performing the same operations on an identical (but inverted) bearing structure at the top of the shaft.  The drum may be eccentrically mounted with respect to the housing, Fig. 4 (not shown).

Title: Improved Cleaning Method
Inventor: HITTEL GEORGE THOMAS
IPC: C11D7/50
Filed: 1967-05-31
Abstract: 1,193,186. Cleaning pipes. DOW CHEMICAL CO. 31 May, 1967, No. 25164/67. Heading F2N. [Also in Division C7] Articles of, for example, metal, plastics material, glass or ceramic, are cleaned of adhering material by heating them to a temperature above the boiling point of a liquid which is a solvent for at least part of the material to be removed and contacting them with the liquid. Boiling of the liquid then removes both soluble and insoluble material, giving a better cleaning action than is obtainable by solvent action alone. Heating of the articles cleaned may be by induction, radiation, convection, .conduction or resistance heating, carried out in air, a liquid, an inert gas or a vacuum. Preferred methods are by heating in a boiling liquid and by heating with an induction coil while suspended in a vacuum. The articles may be immersed in the cleaning liquid, or sprayed or flushed with it. The cleaning liquid may be perchloroethylene to which may be added an alkyl aryl phosphate ester ethylene oxide adduct detergent and 0-15% by weight water, or may be benzene, toluene, methylene chloride or Freon 113 (Registered Trade Mark). Two cleaning liquids of decreasing boiling point may be used in succession, and the cleaning liquid or liquids may be under less than atmospheric pressure.
Patent GB-154763-A (GB)
Title: Improvements in and relating to pneumatically-operated controllers for electric motors
IPC: B60L15/32
Filed: 1919-10-14
Abstract: 154,763. British Thomson-Houston Co., (General Electric Co.). Oct. 14, 1919. Master control systems; controllers, actuating mechanically. -Relates to seriesparallel electric motor - control systems, particularly applicable to electric railway motors, of the kind described in Specification 11658/15, in which electro - pneumatic means is provided for automatically operating a series of switches for successively cutting- out the starting-resistances and for making the various connexions necessary for bringing the motors into parallel at full speed. According to the present invention, the pneumatic means effects a step-by-step control by means of a main piston which operates the controlling-member, and an auxiliary piston, which is operated alternately with the main piston and is also retarded so as to give an intermittent action, delayed by a perceptible interval, to the main piston. The two main pistons 15, 16, Fig. 2, located in the cylinders 10, 11 are rigidly connected by a rack 18, which operates the controlling-member for the unit switches 38 through a gear-wheel 36. The auxiliary pistons 14, 17 are joined by a rack 19 which is connected through reducing-gearing 25 with a retarding-device 26, shown as an electro-magnetic brake. Should the current be above the proper value, the brake operates to stop any movement of the controller. Both pairs of pistons 14, 15 and 16, 17 are provided with conical valves 22, 23 which are connected by a lost-motion connexion 24, as shown in Fig. 5. Two electro-magnetic valves 39, 40 control the flow of compressed air to the cylinders 10 and 11 whilst similar valves 41, 42 actuate the reversing-switch RS. Normally the valve 39 is open to the compressed-air reservoir, whilst the valve 40 is open to atmosphere. In this position, pressure on the piston 14, Fig. 5, causes it to move forward alone under the control of the retarding-device until the valve 23 has closed the opening 21 in the piston 15. A slight further movement is allowed by the lost-motion connexion 24, to throw open the valve 22, relieve the pressure upon the piston 14, and admit pressure through the ports 14<a> to act upon the piston 15, which whereupon moves forward to drive the controller until the lost-motion connexion is taken up and the valves 22, 23 re-assume the position shown in Fig. 5. When the windings of the valves 39, 40 are energized, the connexions of the valves to reservoir and atmosphere are reversed, and the pistons are moved in similar steps to the left. The general circuits are similar to those described in Specification 11658/15, provision being made for energizing the winding of the retarding-device 26 so as to cause it to act as a positive stop to the movement of the controller so long as the current is above the proper value.

Title: Shutter control for motion picture apparatus
IPC: G03B9/10
Filed: 1931-09-08
Abstract: 386,360. Kinematograph apparatus. Kinematograph apparatus. VICTOR, A. F., 242, West 55th Street, New York, U.S.A. Sept. 8, 1931, No. 25230. [Class 97 (i).) In a camera in which a rotary element of the film feeding mechanism rotates the shutter, a shutter control for stopping the shutter in a position obturating the exposure opening comprises mechanism for releasing and stopping the film feeding mechanism, the latter having a rotary element, the movement of which is positively related to the rotary movement of the shutter for determining the stop position of the shutter with respect to the exposed aperture. As shown in Fig. 2, the speed at which the filmfeeding mechanism operates is controlled by the degree of engagement of the clutch ring 15 with pivoted brake shoes engaging its internal surface, and the position of the clutch ring 15 is controlled by engagement with a roller 29 on a cam 26 pivoted at 27 and capable of being rotated to a predetermined extent by the depression of the plunger 31. The shutter 57 is provided with a counter-balance hub 53 of cylindrical shape having a flattened portion 70, co-operating with which is an arm 71 projecting from the cam 26, and in this position the control plunger 31 is fully raised to apply the brake and prevent film-feeding. On depression of the plunger 31 the brake releases the film-feeding mechanism and the arm 71 is raised so that it clears the cam 53 and allows the shutter 57 to start in synchronization with the film-feed. When the plunger 31 is released the end of arm 71 presses on cam 53, and will not move to normal position and allow the brake to be applied to the feeding mechanism until the arm rests on the flattened portion 70 of cam 53 and the exposure aperture is obturated.

Filed: 1962-07-03
Abstract: 994,808. Converting. HOOVER CO. July 3, 1962 [July 5, 1961], No. 25444/62. Heading H2F. A D.C. to D.C. converter comprises a pair of transistors 5, 6 and a saturable transformer with two centre-tapped windings connected as shown. When the source voltage, which may be low, is applied one transistor, say 5, conducts more than the other and current flows from its emitter through the base and part winding 16 to the load. Simultaneously, current flows from the emitter to the collector of transistor 5 and through the part winding 14 to the other terminal of the battery. This second current increases the load voltage by transformer action, and the induced voltages in the windings bias transistor 5 fully conducting and transistor 6 fully cut-off. When the transformer, which preferably has a " square loop " core, becomes saturated the bias voltages vanish, transistor 5 ceases conduction and transistor 6 conducts as there is now a high voltage between its emitter and collector, and the new currents, which also make terminal 22 positive flow until the transformer is saturated in the reverse direction, when the cycle is repeated.
