Title: Improvements in or relating to the manufacture of mineral water and the like
IPC: B01F3/04
Filed: 1935-02-04
Abstract: <PICT:0451354/III/1> A radio - active, carbonated, liquid and a radio - active gas suitable for subsequent use in producing aerated beverages are produced by forcing carbon - dioxide under high pressure into a closed cylinder containing water or brine and superposed layers of gravel, granulated coke, and a radio-active material such as monazite sand or uranium ore.  As shown, the cylinder A with the stated layers of materials C, B, D, is partly filled with water by the inlet H, and carbon-dioxide from the cylinder L is forced in until the air present in the cylinder A has been expelled and a pressure up to 50 lbs. per sq. inch is established.  This condition is maintained for about three weeks, additional gas being added from time to time to replace that absorbed by the water.  At the end of this period, the cock F is opened and the radio-active gas is expelled into a gasometer N, and can be used for making mineral waters.  The radio-active water or brine may be drawn off by a cock K and stored in wooden casks for drinking or therapeutical purposes.  Electrodes O may be provided for ionizing or sterilizing the water in the cylinder.

IPC: G01N11/14
Filed: 1929-02-02
Abstract: 305,242. Yacco, Soc. Anon. Feb. 3, 1928, [Convention date]. Testing and measuring viscosity of liquids. -The apparatus is of the type employing coaxial cylinders or coaxial discs for measuring the coefficient of intermolecular friction of a liquid or of a liquid with respect to a surface. An element a, cvlindrical on the exterior, is mounted within a hollow cylinder b and both elements are provided on the parts facing one another with teeth a<1>, b<1>, filledwith the oil to be tested, which is fed into the annular space between the cylinders by means of a tube c. The element a is rotated at a definite constant velocity and the torque required to stop the cylinder b from rotating is measured by a dynamometer. The coefficient of friction of an oil against a surface can be obtained by replacing the cylinder a by another cylindrical element of the same nature as the surface to be considered. For conducting the experiments at different temperatures a thermometer f is connected to the inlet tube c. In a modification of the apparatus, the cylinder b is rotated at a definite constant velocity and the torque on the inner cylinder a measured. In another form of the apparatus the coaxial cylinders are replaced by coaxial discs.

Title: Improvements in and relating to friction clutches
IPC: F16D13/71
Filed: 1928-02-08
Abstract: 285,082. Russell Manufacturing Co., (Assignees of Tower, E. V. J.). Feb. 11, 1927, [Convention date]. Clutches, friction.-The release-levers of a friction clutch for motor-vehicles are floatingly mounted and have a so-called movable fulcrum, constituted by an arm which bears by a ball or other artificial means on a curved raceway on the driving-member. The clutch shown comprises a driving-member 5 screwed to or integral with the flywheel 2 and screwed to a plate 7, which slidably carries studs 30 secured to the presser-plate 37, coacting with the driven ring 43. The presser-plate is preferably flexible or not quite rigid, in order that it may exert uniform grip on the friction ring 43, which is carried by flexible spokes 44, shaped and assembled as shown in Fig. 4. The inner ends of the spokes and an asbestos &c. heat-insulating ring 48 are held between flexible washers 45, clamped between integral and loose flanges 49, 50 on a bush 47 splined to the driven shaft 3. The plate 7 is secured to a central plate 9 carrying a shaft bearing 10, on which slides the shifting-sleeve 11. This sleeve has a slotted flange 12 to guide the declutching-levers 13, a ball thrust bearing 15, and a housing 18 containing oil to lubricate the sleeve 11 and bearing 10. Where the clutch is remote from the transmission-gear elements 1, the shaft 3 has an independent bearing, the parts 9, 10 being omitted and the sleeve 11 &c. replaced by a simple ball thrust collar. Pairs of springs 40, symmetrically situated about the studs 30, bear on the presser-plate 37 and on loose cups 41 having self-centring spherical seatings in the plate 7. If the clutch is to run in oil, the open ends of cups 41 are closed by caps. In order to give gradual engagement, one spring of each pair is made effective before the other by varying the depth of the seatings 42 in the non-rigid plate 37. The studs 30 carry washers 31, adjusted by fine-thread castle-nuts 32 and engaged by the forked ends 13<a> of the levers 13, which pivot on pins 20, mounted with a loose fit in forked brackets 21 on plate 7. In the fork 13<a> of each lever is a block 25, rotatable on the pin 20 and provided with a ball 26 engaging a race 29, Figs. 1 and 5, secured to plate 7 or integral with the bracket 21. It is stated that when the levers 13 are actuated to withdraw presser-plate 37, the balls 26 roll on the races 29 towards the studs 30 and give a variablefulcrum effect, so facilitating declutching. Lubricant is contained in the bores 27 of the blocks 25. Each stud 30 is driven from plate 7 bv contact between a bush 35 and two inclined sides of a squared part 34, one corner of which is cut away to clear the race 29. The bushes 35 may be omitted, the metal about the square holes in plate 7 being then extended on the two driving-faces to form bearing-surfaces for the studs. In a modification, the blocks 25 are integral with the levers 13.

IPC: C01B6/04
Filed: 1959-02-04
Abstract: <PICT:0877510/III/1> An alkali metal hydride is prepared by passing a liquor containing molten alkali metal, an inert liquid, and alkali metal hydride at a controlled rate upwardly in each of a plurality of series-connected vertical reactors, introducing H2 at the first reactor to maintain an atmosphere of H2 in each reactor under pressure, maintaining the liquor in each reactor at a temperature at which H2 reacts with the alkali metal, agitating the liquor in each reactor to form a dispersion of the metal and hydride in the inert liquid, introducing molten alkali metal and inert liquid into the first reactor in amounts to provide a liquor containing 10-40% alkali metal, and recovering alkali metal hydride dispersed in the inert liquid at the controlled rate from the last reactor.  Each reactor is provided with at least one agitator and (1) the ratio of the internal diameter of the reactor to the outside agitator diameter is greater than 1 but less than 20, (2) the ratio of the volume occupied by liquid during the operation in each reactor in gallons to the cube of the outside agitator diameter in inches times the number of agitators is greater than 0 but not greater than 1.5, and (3) the agitator peripheral speed in feet/min. times the number of agitators is greater than 500 and less than 20,000. Molten Na is fed from melting tank 15 by inert gas pressure through filters 17, 19, weighing device 18 and pump 16 into the lower portion of reactor 10 at a controlled rate.  Controlled amounts of inert high-boiling liquid, e.g. mineral hydrocarbon oil, are fed from tank 28 pump 30 meter 31 and mixing valve 32 to reactor 10.  Tank 34 and heater 35 are provided for hot oil, which may also be fed to mixing valve 32 in response to temperature regulator 36.  Reactor 10 is thus provided with a dispersion of Na, and the reactor has a hot oil jacket, motor driven agitator 12 working at 2,300 r.p.m. and baffles, while the temperature in 10 is 270 DEG C. rising to 350 DEG C. H2 from 21 passes through pressure regulators 23, 24 and meters 25, 26 into the lower portion of reactor 10 to establish a pressure 25-250 p.s.i.g. After the major portion of the Na has reacted, the resulting solution, including H2 to establish a constant pressure atmosphere thereabove, passes through 38 to the lower portion of reactor 11. Reactor 11 has agitator 12 and is jacketted with cooling oil. Product oil dispersion of NaH is withdrawn to tanks 41, 44, and may be withdrawn at 50.  Agitators 43, 47 maintain solids in dispersion. KH and LiH may be produced in the same manner.

[Class 7 (i)] [Also in Groups XXXIII and XII] A power unit or engine, particularly for the propulsion of aircraft, ships &c. operating on the jet or reactive principle comprises an explosion chamber in which the charge to be ignited is compressed by means of one or more reciprocating pistons carried by a central member between which and an outer casing a relative rotary movement is produced by the reciprocation of the pistons. In the construction shown in Fig. 1 a single or common explosion chamber h is mounted in a preferably stationary outer casing b, b<SP>1</SP>, b and is fitted with spring-loaded flap valves i or with camcontrolled valves adapted to open substantially at the time of each explosion. By means of a charging port l<SP>1</SP> the chamber h is connected successively via ports l with a series of cylinders c<SP>2</SP> in the central member a in which reciprocates a corresponding series of pistons c. Each piston carries a pair of diametrically opposed spring- pressed balls e, f which respectively engage curved grooves d in the casing b and straight longitudinal grooves g in the central member a so that, as the pistons reciprocate, relative rotation is produced between the parts a, b. The pistons c are reduced at their one end c<SP>1</SP> and the reduced ends operate in cylinder spaces c<SP>3</SP> into which an explosive mixture is introduced and ignited to effect the reciprocation of the pistons. The cylinders c<SP>2</SP>, c<SP>3</SP> communicate by way of inlets n<SP>1</SP> with an intake n for a gaseous mixture and the chamber h and cylinders c<SP>3</SP> are fitted with sparking plugs, or, alternatively, the chamber h and cylinders c<SP>3</SP> may be fitted with fuel injection nozzles and air alone admitted by the intake n. If desired, the cylinders c<SP>2</SP>, c<SP>3</SP> may be arranged on the casing, while the central member may be fixed and the casing made rotatable, or both may be rotatable so long as relative rotation occurs. In a modification, Fig. 7 a series of explosion chambers equal in number to the pistons c is provided, the chambers, co-operating in succession with an eccentric valve-controlled opening s in a cover g secured to the casing b<SP>2</SP>.
