Title: Improvements in and relating to remote control fluid distribution systems
IPC: B60R17/02
Filed: 1926-03-13
Abstract: 261,967. James, R. W., (Bijur, J.). March 13, 1926. Single-acting, suction-valveless bucket pumps; lever-and spring-operated pumps; strainers; suction reservoirs.-A spring-discharged bucket pump for lubricant or other liquid is of relatively large diameter and small stroke, the cylinder 11 being secured in and protruding below the bottom of a reservoir R and the piston rod 12 being guided in a bushing 13 in the top of the reservoir and engaged by the forked smaller arm of a pedal lever L. A cap 17 having a discharge outlet 18 is threaded on the lower end of the cylinder and contains a filter disc 27, sustained on an embossed. wire screen 28, and a disc 20, against which the piston is adapted normally to rest so as to close an aperture 21 therein and prevent leakage. The piston comprises oppositely-flanged metal and leather cups 32, 33 with metal backing discs 34, 35 secured between the end of a socket 37 and a shoulder 41 on a plug member 40 threaded into the socket, which latter is attached to the end of the rod 12. A strainer cup 51 encircling the rod has its rim engaged between the disc 34 and the flange of the cup 32. A seating disc 42 backed by a metallic disc 43 and co-operating with the disc 20 is secured in the lower end of the plug 40. A ball valve 45 housed in the plug rests on a pin 46 and co-operates with a seat 50. A spring 52, which even in the normal discharged position of the piston is highly stressed, is arranged between the bush 13 and the cup 51. The reservoir R is attached to the front of the dashboard D of a motor vehicle by a bracket 54, and the lever L, which extends through the dashboard, is pivoted on a pin 56 in the bracket. The upper faces 59 of the forks 58 of the lever are inclined and engage correspondingly flattened ends of a loose pin 60 in the rod 12, being held against the pin by a spring 63. When the pedal L is depressed, lubricant passes from the reservoir through apertures 48, 49 to the space below the piston, and, when realeased, the spring 52 causes the lubricant to be discharged. If the pump is operated when the reservoir is empty, the heavy valve 45 does not close during the discharge stroke, so that air cannot be forced through the outlet. Specification 237,958 is referred to.

Title: Improvements in and relating to froth flotation agents
IPC: B03D1/012
Filed: 1936-03-09
Abstract: A thiocarbanilide derivative which is very finely divided and more soluble in water than thiocarbanilide itself is precipitated by mixing water with a solution of thiocarbanilide in sulphuric acid. The product, which is used as a froth flotation reagent, may be separated from the acid and used in the dry state or made into a sludge with water, or may be used as a sludge or a suspension in the dilute acid solution from which it is precipitated.  The derivative may be precipitated on an inert insoluble carrier such as diatomaceous earth.ALSO:A froth flotation reagent is prepared by dissolving thiocarbanilide in sulphuric acid and mixing the solution with water to precipitate a derivative which is very finely divided and is more soluble in water than thiocarbanilide itself.  The precipitate may be separated from the acid and used in the dry state or made into a sludge with water, or may be used as a sludge or a suspension in the dilute acid solution from which it is precipitated. Alternatively, the acid solution may be added direct to the pulp, the water in the pulp causing precipitation of the derivative.  The derivative may be precipitated on an inert insoluble carrier such as diatomaceous earth which may be added to the pulp either dry or as a sludge.  The concentration of various mixed sulphide ores is described.  A mixed lead and copper concentrate may be obtained from an ore containing lead, copper, zinc, and iron sulphides either by direct flotation with a mixture of the thiocarbanilide derivative and cresol, or by adding sodium cyanide which depresses the zinc and iron and part of the copper, adding sulphuric acid to reactivate the copper, and then floating with the derivative and cresol.  A lead-zinc-iron ore may be floated with the derivative, cresol, and sodium hydroxide with or without sodium cyanide to give a lead concentrate, the zinc being then floated, using copper sulphate and derivative, and the iron, if desired, being finally floated with xanthate.  A copper-zinc-iron ore may be treated with sodium cyanide or zinc cyanide to depress the zinc and iron and, in part, the copper, and a solution of this carbanilide in concentrated sulphuric acid then added.  The derivative is precipitated and the copper is reactivated by the sulphuric acid and can then be floated with the addition of a frothing agent.  Alternatively, the sulphuric acid and the derivative may be added separately.

Title: Electromagnetic beam defelction yoke
IPC: H01F41/08
Filed: 1973-02-13
Abstract: 1407166 Electron beam electromagnetic deflecting systems MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 13 Feb 1973 [16 Feb 1972 28 Feb 1972 (2)] 7115/73 Heading H1D A deflection yoke for a TV picture tube (e.g. three beam shadow mask type) comprises at least two deflection coil units 1, 2, each unit including a main coil and an auxiliary coil, the latter overlapping the former and wound such that the current in the auxiliary coil at one part of the main coil is in an opposite direction to that at another part of the main coil, the coil units generating a pincushion magnetic field at at least the screen end portion of the yoke and a bevel field at one other portion of the yoke. In Fig. 2, units 1 and 2 each have vertical and horizontal deflection coils, the units being held by C-shaped spring 3 having projections 4 co-operating with slots 6 in housing 5, the latter fixed to the tube neck by band 7. In Fig. 3 (not shown), ferromagnetic ring 8 carries main coils 9 and auxiliary coils 10. The current in part 10a is opposite to that in part 10b, and in part 10a is the same direction to that of main coil 9, but in part 10c is opposite to that of coil 9. The transverse magnetic field (e.g. curve, b 1 , Fig. 4, not shown) may be changed without changing the form of the axial field (curve a 1 ). Coil 1 produces the barrel field and coil 2 the pincushion field, and since the difference in areas under curves corresponds to convergence distortion, correction may be made by adjusting the intensity and ratio of current flow in the respective auxiliary coils. Three coils units (Fig. 5, not shown) may be used, two producing pin cushion fields and one, a barrel field (Fig. 6, not shown). Reference is made to pin cushion distortion due to tube shape.

Title: Improvements in or relating to transmission mechanism of the v-pulley type
IPC: F16H9/16
Filed: 1944-04-19
Abstract: 575,972. Variable - speed gearing. P.I.V. CHAIN GEAR.S, Ltd., and ABBOTT,. G. J. April 19, 1944, No. 7213. [Class 80 (ii)]. In variable-speed gearing having V expanding pulleys, a flange of at least one pulley is connected to the member which it drives, or is driven by, thiough one or more rocking eccentric sectors pivoted on one member and rolling against the other, so that as the flange turns relatively to the said member the sectoi rolls round and forces the flange axially towards the companion flange. Thus the tension in the driving belt is maintained in accordance with the torque transmitted. As shown, expanding pulley flanges A<1>, B<1>, on driving and driven shafts A, B, are connected by a chain belt D. The flanges have radial ribs and the chain D has slat-like members D' of the kind described in Specifications 228,838 and .242,416, [both in Class 80 (ii)]. The flanges A<1> are splined on the shaft A and are connected to cross-beams L by links L<2> and thrust collars A<2>. The flanges B<1> are connected so that they rotate together by teeth on one flange engaging a slotted sleeve on the other flange. Both flanges are mounted freely on sleeves E splined to the shaft B and connected to the beams L by links and thrust collars B<2>. Springs. F force the flanges B<1> towards one another. Between each sleeve E and the adjacent flange B<1> is a pair of eccentric. sector plates J. Each plate J is pivoted at J<1> on a sleeve E and its curved face rolls in contact with the outer face of a flange B<1>. Each curved face, which may be composed of circular arcs of different centres, approximates to a logarithmic spiral, so that as the sector rolls in either direction from its central position it forces the flange towards its companion flange. A pin K, formed like a gear tooth, on the flange B<1>, engages a recess J<2> in the sector J to prevent slip. The crossbeams L are pivoted at L<1> to blocks screwed on a shaft P and engage nuts L<4> screwed on a shaft L<5>. Thus, gear changing is effected by rotating the shaft L<5> by hand wheels L<6>, and the initial tension of the chain belt D may be adjusted by rotating the shaft P. A gearratio indicator pointer M on a spindle M<1> is actuated from the shaft L<5> by a nut L<4> and links M<2>, M<3>. Adjustable stops N and movable nuts N<1> limit the range of gear adjustment.

Title: Improvements in and connected with liquid-bottling machines
IPC: B67C3/08
Filed: 1945-03-22
Abstract: 600,359. Bottling. WORSSAM & SON, Ltd., G. J., and FOX, D. P. S. March 22, 1945, No. 7247. [Class 125(ii)] In a rotary multi-head bottling machine, for example of the type described in Specification 503,926, in which bottles 14 are filled against counter pressure with liquid from an annular tank 1 and the filling level is determined by pressure in the bell 23 within a pressure chamber 22, the bottom of the annular tank is provided with an annular channel 46 to which the counter pressure is connected by a pipe 19 leading from the air space in tank 1, and an annular channel 38 to which the levelling pressure is connected by pipes 21 leading from pressure bell 23. Level control chamber 22 is situated apart from the filling machine, and air pressures in chamber 22 and tank 1 are equalised by connecting tube 25. Channels 46, 38 comprise grooves in the tank bottom which are closed by a joint ring 52 supplied with ports communicating with the filling heads 11, the flanged tops 48 of which are bolted to the tank. Bottling is controlled by conical plug valve 12 with a port 65 whose openings are at right angles. Successive 90 degree movements of star wheel 75 connect the bottle through passages within the filling head with firstly counter pressure from channel 48 and secondly levelling pressure from channel 38, when the eccentric 17 opens valve 16 to admit liquid as described in Specification 503,927. Wear of plug valve 12 due to side thrust from star wheel 75 is reduced by the provision of a substantially universal coupling 74 jointed to the star wheel by a loose square plug and socketconnection and to plug 12 by a rib and groove connection as described in Specification 600,400. Star wheel 75 is actuated by two short stops 89, 90 which engage outer points 85, 86 and two long stops 91, 92 which engage inner points 87, 88, Fig. 6, the stops being mounted on fixed brackets. Stop 89 is an auto-stop held in operative position, Fig. 4, by fluid pressure acting on piston 101; if no bottle is present on the filling head or if a breakage occurs, a trip mechanism (not shown), releases the fluid pressure, and stop 89 is withdrawn. At the start of a filling cycle, the star wheel is in position A, Fig. 6, and is subsequently moved by stops 89, 91, through position B to position C, when the bottle is connected with levelling pressure and filling commences. When filling is complete, the star wheel is reversed to its initial position by stops 90, 92. Safety stops 97, 98 are provided to correct any accidental displacement of the star wheel prior to the start of the next cycle. If auto-stop 89 is withdrawn, point 86 is not initially engaged, and valve 12 remains closed. Eccentric 17 is fitted with a stem 71 for dislodging ball valve 73 after jamming due to rush of liquid upon bottle breakage &c. A similar ball valve is provided at the base of the passage connecting channel 38 with plug valve 12, and can be cammed out of its seating by rotation of valve 12. The bottle lifts may be those described in Specification 589,413.
