Title: Apparatus for transforming the pressure and output of a fluid current, based upon the principle of the hydraulic ram
IPC: F04F7/02
Filed: 1925-01-21
Abstract: 245,605. Faure, E. Jan. 21, 1925. Hydraulic rams. - Apparatus for transforming the pressure and output of a fluid currant on the principle of the hydraulic ram comprises an inlet chamber 1 for the primary current communicating with a number of conduits 4, the discharge ends of which are controlled by a rotary valve 5 provided with ports 9, 7 for connecting the conduits alternately to a low-pressure, chamber 10 and a delivery pipe 8 respectively. The rotary shaft 6 of the valve 5 may carry an axially adjustable valve 14 for varying the communication between the chamber 1 and the conduits 4. Conversely, if a high pressure current is introduced by the pipe 8, low pressure fluid in the chamber 10 will be drawn through the pipes 4 and a current of greater volume but diminished pressure will be delivered from the chamber 1. In the multi-stage form shown in Fig. 5, the primary current passes from the inlet chamber 26 through a number of conduits 28 controlled by two rotary valves 29, 32. The fluid passes from each conduit successively through chambers 33, 34, 35, 30 at successively higher pressures to the dedivery passage 31. Additional chambers 40, 41 may be included in the series. In the form shown in Fig. 7, the fluid passes from the inlet chamber 43 through the multiple conduits 44 and from the conduits alternately into the low pressure chamber 45 and the high pressure delivery passage 49. The rotary valve 48 is carried by a sleeve 47 which may be axially adjusted by the differential nut 53 to hold the valve face close to the ends of the conduits 44. Each conduit is connected by a passage 57 to an expansion chamber 54 to relieve excessive pressure when the wall of the valve closes the end of the conduit. In the form shown in Fig. 13, a rotary pump 77 with inlet 78 and delivery 81 discharges into a number of conduits 84 controlled by rotary valves 82, 83 through which the conduits deliver alternately into the suction chambers 79, 80 of the pump and the high pressure chambers 89, 90 of the pressure transformer.

Filed: 1971-01-14
Abstract: 1342306 Purifying I C engine exhaust gases; ignition systems; timing ignition TOYO KOGYO CO Ltd 14 Jan 1971 [14 Jan 1970 25 April 1970] 1932/71 Heading F1B In an arrangement for purifying I.C. engine exhaust gas, a means 4 for supplying secondary air to an exhaust gas after-burner is operated at engine speeds below 4000 rpm when the engine is warming up and at engine speeds below 2000rpm when the engine is hot. For this purpose, a temperature detector 1 sensing the temperature of the cooling water, oil or exhaust gas operates a relay 2 when the engine has warmed up to move a movable contact 2a from a fixed contact 2b to a fixed contact 2c, whereby the battery voltage is transferred from a movable contact 3a of an engine speed detector 3c to a movable contact 3a. Contact 3a is closed against a fixed contact 3b at speeds below 4000rpm whereby the secondary air supply means 4 (which may include an electromagnetic clutch of an air pump, or a solenoid valve) is operated in this speed range if the engine is warming up. Contact 3a' is closed against a fixed contact 3b' at speeds below 2000rpm whereby the means 4 is operated in this speed range if the engine is hot. The engine may be of rotary piston type with two spark plugs 7a, 7b in one combustion chamber. Plug 7b is always in operation, while plug 7a is brought into operation when the engine is hot, via contacts 2a, 2c. When the engine is still warming up, the plug 7a is brought into operation only if the engine is idling, decelerating or operating under full load, via a vacuum switch 10, or if the speed is above 4000rpm, via contacts 2a, 2b, 3a, 3i. In a modifcation, Fig. 2 (not shown), the speed detector has two separate sensors (3e, 3f) for the two speed ranges, the two sensors operating a common set of contacts (3d, 3g, 3h). The switch contacts may be replaced by contactless switching circuits using transistors. Instead of being brought out of a non-operative state, the plug 7a may be brought out of a retarded-ignition state.

Title: Data entry device
IPC: G09G3/14
Filed: 1975-01-14
Abstract: 1475886 Selective signalling DEFENCE SECRETARY OF STATE FOR 14 Jan 1975 [16 Jan 1974] 02093/74 Heading G4H A data entry device for entering data into data handling apparatus includes a display matrix array of characters one of which can be indicated under control of horizontal and vertical reversible selection counters, there being separately operable character entry means for enabling a signal corresponding to the character indicated at the time being to be entered into the data handling apparatus. A hand-held unit has on its front face two matrix displays for letters, and numerals and signs respectively, there also being 8 bars arranged radially in a circle projecting through the front of the casing and mounted on a disc within the casing. Behind the disc are 4 switches, depression of one of the bars closing either one switch or two adjacent switches. The 4 switches control incrementing and decrementing of horizontal and vertical counters respectively, the counts being decoded to energize a character in one of the matrices selected by a shift latch controlled by a shift selector switch on the front face of the unit. The outputs of the counters and the shift latch are supplied to a programmable read-only memory to translate them into an output code. On the back of the unit is a handle bearing a space preset button, pressing of which produces an output "data valid" pulse, and resets the counters to a standard position. Feedback from the decoders prevents the counters from being incremented/decremented off the display during use. Any change of state of the shift latch is detected (a) to remove the power supply to the counters so that their outputs go to all ones which, together with the output of the shift latch, is translated into a "change to upper shift" or "change to lower shift" output code, and (b) to produce the same effect as the space/ reset button. The displays may use light emitting diodes or liquid crystals.

Title: Improvements in or relating to offset presses
IPC: B41F7/30
Filed: 1944-02-04
Abstract: 574,595. Printing-machines. WARSDEN, H. E. Feb. 4, 1944, No. 2125. [Class 100(ii)] [Also in Group XXIX] The lithographic printing - plates such as are used in rotary offset presses are damped by means of sprays of atomized fluids which are applied directly to the plates by means of a number of spray nozzles, which as shown are supplied with water from a tank 24, Fig. 1, connected by a pipe 30 to a water manifold 33, Fig. 3, and with compressed air supplied by a pump 27 to a manifold 32 via a reducing valve 108 which permits of control of the force of the spray. A number of spray nozzles are used, but some can be put out of action if a narrow plate is used, and each spray is fitted with independent controls for the air and water supply, but the active nozzles are put into and out of action simultaneously, although they may be controlled so as to deliver an air blast only to dry the printing-plate, and finally the nozzles are set so as to deliver an atomized spray. The nozzles are arranged in a box-like spray guard S fitted with ends adjustable longitudinally for dealing with narrow plates, the guard S being formed with a drain channel 105 leading by a pipe 29 to a tank 28 or to waste. The sprayers are connected by stirrup fastenings 31 and bolts 34 to the manifolds 32, 33, and the air supply to the sprays is controlled by a valve 52 governed by an adjustable spring 57, and the air passes to a chamber 44 and inclined ports 46 to entrain water delivered to a nozzle 41 under control of an adjustable spring-controlled needle valve 48. The valves 48, 52 are con- - trolled by cams 61 detachably secured to a shaft 62 which is manually adjustable by an arm fitted with a pointer 68 moving over a scale 67. Each sprayer is fitted with an adjustable cam follower 63 on a lever 58 pivoted at 58a and provided with a U-shaped member 59 which actuates the air valve 52, and a projection 60 which actuates the water valve 48 subsequent to the actuation of the air valve. In a modification, Fig. 10, the means for controlling the sprays is so mounted as to be out of-operation when the press motor is not running. The control shaft 62 and associated devices as described above are mounted in swinging bearing brackets 75 which are normally maintained by tension springs 78, in such position (counter-clockwise of the position shown in Fig. 10), that the cams 61 do not contact with the cam followers of the levers 58. On starting the motor of the press, an electromagnet 83 is energized and its solenoid 84 actuates a lever 85 against the action of a spring 88 to move the brackets 75 clockwise and bring the cam 61 into the position shown in Fig. 10 in which the cams can operate the levers 58. In a further modification applicable for printing sheets by a machine in which a segmental plate is used, the action of the spray means is interrupted by cam means so as to act only upon the plate portion of the plate cylinder.

Title: Method and apparatus for the treatment of fluids with chemical reagents
IPC: C02F1/68
Filed: 1945-01-29
Abstract: 5 9 9 , 4 9 9 . Mixing fluids in flow. CORYDON, J. Jan. 29, 1945, No. 2262. Convention date. Jan. 29, 1944. [Class 86] [Also in Group XXVIII] Apparatus for adding a reagent in proportionate quantities to a fluid in flow comprises means for pumping reagent from a container and injecting it intermittently into a fluid conduit in uniform unit volumes at a rate in excess of 150 injections per minute, the rate being predetermined in proportion to the fluid flow volume, means being provided for changing the rate of injection to correspond with variations in the quality of the fluid being treated. In the treatment of a water main with sodium or calcium hypochlorite, the reagent is fed to an inlet 28, Fig. 2, and through a suction valve 30 into the cylinder 20 of a pump comprising a reciprocating piston 27 secured to a diaphragm 22. The piston pushrod is actuated by an eccentric cam 56 rotated from an electric motor 44 by driving means comprising a belt 48 carried by pulleys 46, 49. The motor 44 is run continuously and is clutched and declutched at intervals by means of a solenoid 45 operated by a timer of known type connected to a flow meter in the water main. The pulley 49 drives by means of belts 50, 53 the shaft 55 carrying the cam 56. The pulley 46, Fig. 4, is of a variable speed type and has two separable conical faces 47 which are normally spring-pressed towards each other. To compensate for any changes in the quality of the water, the rate of injection of the pump may be adjusted by the manual rotation of a control knob 58 which operates a screw 57 to move the base-plate 43 on which the pulley 46 is mounted. Movement of the pulley 46 relatively to the belt 48 produces an alteration in the separation of the faces 47 and a change in the speed of the belt 48. The electric motor may be replaced by a water turbine or by a petrol engine. Several reagent pumps may be operated by a single driving mechanism and means may be provided for both the individual and the simultaneous adjustment of the supplies of the reagents.

Title: Process for the production of copolymers of predetermined composition and the copolymers so produced
Filed: 1951-01-31
Abstract: Heterogeneous copolymers are prepared from a mixture of monomers in which the ratio of monomer concentrations differs from that in which the monomers unite, in which process the ratio of the monomer concentrations is altered according to a predetermined scheme by adding and/or removing one or more monomers during the polymerization and in which the variations of a measurable physical property, which is a function of the concentrations of two of the monomers, are observed in order to indicate changes in the ratios of the monomer concentrations.  Suitable physical properties are specific gravity, vapour pressure, refractive index, dielectric constant, extinction coefficient in infra-red and, particularly for gaseous monomers, thermal conductivity.  In the latter case, separated monomer mixture is conducted to a cell containing a resistance wire forming part of a Wheatstone bridge network.  Alterations in the monomer composition effect the conductivity of heat away from the wire and are reflected in the galvanometer.  A standard gas mixture is preferably employed in a cell in a parallel branch of the network, this mixture preferably consisting of the same monomers as are being checked and in the ratio desired in the mixture being controlled.  The process may be carried out batchwise or continuously and in emulsion.  In a continuous process the mixture may flow through tubular reactors or through one or more reaction spaces connected by conduits, and the monomer mixture is checked, respectively, at various points in the tube or in each reaction space.  The examples describe the copolymerization of vinyl chloride with vinyl acetate and vinyl chloride with vinylidene chloride in both of which polymerization is begun in a suspension containing preformed heterogeneous copolymers of the desired compositions.  The products may be plasticized and formed into films.
