Patent GB-276727-A (GB)
Title: An improved process and apparatus for the dispersion of solids in liquids
IPC: B02C7/10
Filed: 1926-05-29
Abstract: 276,727. Whatmough, W. H. May 29, 1926. Emulsions, making.-In the production of dispersions of solids in liquids, such as pigments in oily or aqueous media, discs having a relative rotary motion one of which is wholly or partly faced with a yielding or flexible material, have superimposed thereon a reciprocatory motion so as to produce the smearing or wiping action described in Specification 276,400. The discs are normally flat, but curved or spherical discs may be employed, the reciprocatory motion being transformed from a straight line to a line along the arc of curvature of the grinding members. In the form shown, the lower disc 5 is rotated and the upper disc 10 is given a reciprocatory movement. Rotation is imparted to the disc 5, through bevel gearing 7, 8, from a shaft 3, and the disc 10 is reciprocated by a cam 27 on the shaft 3 through a frame 13 on which the disc is carried, a roller 26 on an arm 25 of the frame engaging the cam groove. The upper disc 10 is carried by a shaft 14 connected to radial arms 12 in a central well 11, the shaft being supported by the engagement of a collar 19 thereon with the head 29 of a screwed sleeve 30 capable of sliding, but not rotating, in the frame 13. Adjustment of the distance between the plates is effected by a crankoperated worm 17 and a worm-wheel 15 mounted in the frame 13 and screwed to engage the sleeve 30. Material is supplied to the discs through the central well 11 by a pivoted spout 28 connected by a flexible pipe 33 to a supply hopper. To facilitate the entry of coarse material to the discs, a bevel 11<a> is formed round the central well, the bevel being increased in size, if necessary, until the disc 10 assumes an arch shape. For cleaning purposes, the disc 10 may be raised by a forked lever 22 engaging the collar 19, and the spout 28 by a lever 31. The treated material from the discs is guided by a surrounding wall 34 to a delivery shoot. The flexible material, e.g. plush or leather, may be inserted in a groove 48, Fig. 9, or may take the form of a depending apron 51, Fig. 8. In, a modification, the upper disc is fixed and a combined rotary and reciprocatory motion is imparted to the lower one. A number of upper discs may be used, each with its own central feed, or one large disc may be provided with several feeding apertures. The temperature at which the operation is carried out may be varied by heating or cooling the materials or the stationary disc or both discs.

Title: Improvements in or relating to impulse sending devices of the dial type
IPC: H04M1/31
Filed: 1924-06-04
Abstract: 226,152. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Obergfell, H. F.). Dec. 10, 1923, [Convention date]. Centrifugal governors; driving mechanism. - Comprises the following improvements in governors for automatic telephone impulse-transmitters. (1) The worm wheel 9, Fig. 7, for driving the governor spindle is made from a sheet of oil-retaining material such as black fibre between two sheets of phosphor bronze. The laminated sheet is driven on to a shoulder of the pinion 7 and the teeth are then cut. (2) The governor spindle 13, Fig. 5, is of hardened steel and is knurled to provide a tight fit for a brass hub 20. The flattened and polished ends bear against hardened chrome-steel balls 21, 22. The ball 21 receives little wear and is held tightly in place. The ball 22 is arranged loosely in a bore in the governor cup and co-operates with a hardened steel rod 24. A brass bushing 25 with a turnedin edge keeps the ball in place. This arrangement causes the spindle to be centred automatically on different axes in response to the rotating thrust delivered by the worm wheel. (3) The fly balls are provided with anti-friction shoes 29, 30 of grey fibre rod &c. and are carried at the ends of a bent spring member 26 of phosphor-bronze formed with a cup which is forced over a collar on the bush 20. The collar is then riveted or prong-staked to secure the springs and the other end of the hub is further secured by ring-staking.

Abstract: 1437552 Reciprocating pumps EI MOCHIDA 28 March 1974 [10 April 1973] 13799/74 Heading F1A [ Also in Divisions B 1 and G1] A pump for preparing diluted liquids with desired degrees of dilution comprises a resilient tube T, e.g. of silicon resin, abutting a flat plate I a plurality of pressing members P 0 , P 1  and P 3  being operable as pinch valves on the tube and pressing members P 2 , P 2 <SP>1</SP> being operable as pumping members for discharging liquid from the tube, a branch tube T' extending from tube T to a pipette C, and tube T being connected to a diluent reservoir FL at one end and to a charging tube N at the other end. A turntable Ta carries test tubes t, and charging tube N and pipette C are movable up and down by levers B2, B4 actuated by eccentrics E8, E9 to charge and discharge the test tubes, pipette C having an optional intermediate position set by a movable abutment B 5 , a joint X in operating rod B 3  taking up the excess movement of eccentric E9. Eccentrics driving the pressing members, turntable, charging tube and pipette are operated in a predetermined sequence by a chain and sprocket drive, Fig. 3 (not shown), so that a charge of diluent is delivered to a first test tube on turntable Ta by charging tube N, a specimen in a preceding test tube is stirred by repeated withdrawal and discharge by pipette C, the specimen then being withdrawn and the turntable rotated so that the diluent-containing test tube is beneath pipette C. The specimen is then discharged from pipette C into the diluent-containing test tube to give a first degree of dilution. In the next cycle, a measured quantity of the diluted specimen is withdrawn by the pipette and added to a further charge of diluent in a succeeding test tube, resulting in a second degree of dilution. Further cycles produce a series of dilutions. The eccentrics may be replaced by solenoids.

Title: Temperature control system
Inventor: WILLSON JAMES ROBERT
IPC: F23N5/06
Filed: 1962-04-10
Abstract: 944,390. Controlling gas burners. ROBERTSHAW-FULTON CONTROLS CO. April 10, 1962, No. 13838/62. Heading F4T. [Also in Division F2] A control device for a main gas burner 16 of an oven comprises a thermostatic valve 50 actuated by a bulb 54 sensitive to the temperature of the oven and a cycling valve 12 for cycling the flow of gas to the main burner when the thermostatic valve 50 is set to maintain the temperature of the oven at the low end of the temperature range. The cycling valve 12 prevents the flow of gas to the main burner when a flame at a heater pilot burner 132 is extinguished and comprises a valve member 90 biased by a spring 92 to closed position and adapted to be opened by a lever 112 pivoted at 110 to a bracket 106. The heater pilot burner 132 heats a mercury bulb 96 connected by a capillary tube 98 to a power element 100 which abuts an adjusting screw 102 passing through an aperture in the lever 112 and threaded into an aperture in a further lever 104 pivoted at 108 to the bracket 106. A coil spring 114 is compressed between the two levers. The heater pilot burner 132 causes the power element 100 to rotate the two levers in a clockwise direction to open the valve member 90. The gas flow to the heater pilot burner 132 is controlled by the thermostatic valve 50 co-operating with the ends of two passages 42, 43 in a seat member 32 screwed into the casing of the thermostatic valve and connected by a hollow connector 30 to a manually-operated gas cock in the form of a hollow tapered plug 26 having an arcuate port 36 for the passage of gas from an inlet 20 to the hollow connector 30 and the seat member 32. Rotation of the plug 26 also causes axial movement of the seat member 32 to determine the temperature to be maintained in the oven. The thermostatic valve 50 is by-passed by an aperture 68 in the hollow connector 30 and an adjustable passage 72 in the valve casing. When the oven temperature reaches the value set by rotating the plug 26 the thermostatic valve 50 closes and shuts-off the gas supply through the two passages 42, 43 to the heater pilot burner 132, but the main burner continues to be supplied through the by-pass 72. The mercury bulb 96 cools and closes the cycling valve 12 to shut down the main burner. When the oven cools the thermostatic valve 50 opens again and the heater pilot burner is ignited by a constantly burning pilot 126. The mercury bulb 96 then opens the cycling valve 12 and the main burner is then fed with gas through the by-pass 72 and through the thermostatic valve 50. When the plug 26 is rotated to set the oven temperature to a high value the arcuate port 36 therein also supplies gas to an adjustable passage 81 which bypasses the heater pilot passages 42, 43 controlled by the thermostatic valve 50. The heater pilot burner 132 therefore remains burning when the thermostatic valve 50 closes and consequently the cycling valve remains open and the main burner is supplied through the by-pass 72.
