Title: Improvements in and relating to the cooling of electric glass container rectifiers
IPC: H01J13/32
Filed: 1930-09-16
Abstract: 358,687. Discharge rectifiers. ELIN AKT.-GES. FUR ELEKTRISCHE INDUSTRIE, 1, Volksgartenstrasse, Vienna. Sept. 16, 1930, No. 27638. Convention date, Jan. 30. Addition to 355,946. [Class 39 (i).] The cooling system for glass rectifiers according to the parent Specification is modified to ensure that the rate of air flow past the condensing chamber is greater than that past the cathode container and the anode arms. In one example, the speeds of the respective air currents past the condensing chamber K, Fig. 4, the cathode L and the anode arms M are determined by vanes LF1, LF2. The surface of the condensing chamber may be increased by means of one or more recesses in which there may be provided vanes LF3, Fig. 4, to guide the air currents as shown by the arrows. The air may be supplied at a pressure of 200 mm. of water and by means of a fan or a blower. In a modification, the air current past the chamber K, Fig. 5, is adapted to co-operate with vanes LF1, LF4 to produce, by injection, air currents for the anode arms &c. In a further modification, Fig. 6 (not shown), . a fan located below the cathode supplies the lowspeed air currents for the anode arms &c.

Title: Improvements relating to fatty compositions
Inventor: HAIGHTON ADOLF JOHN
IPC: A23D7/00
Filed: 1963-07-12
Abstract: Solid and semi-solid fatty compositions (including shortenings, semi-plastic fats, margarine and butter) are prepared by cooling a suitable fat blend containing 0-25% of its weight of water, and if free from water not containing more than 40% of a liquid oil, so gradually from the molten condition to a temperature in the range 10-30 DEG  C as to form a slurry in which the solids content of the fat is in the range 5-50% when measured at 20 DEG  C., and comminuting the slurry so as to produce a composition in which the total crystal surface is not more than 100 sq. m. per c.c. of solid fat, and the major dimension of substantially all the crystals is not more than 15 microns. Aerated shortenings may be prepared by introducing an inert gas, e.g. N2, to the fatty composition just before the comminution stage.  When preparing butter and margarine either an emulsion of a suitable aqueous phase (e.g. milk) with molten fat is cooled and comminuted as above, or the molten fatty phase can be cooled alone and then mixed with the aqueous phase just before the comminution treatment.  Suitable fatty components are described, and apparatus in which the process may be carried out is also described.

Title: Improvements in or relating to change-giving machines
IPC: G07D1/02
Filed: 1938-09-23
Abstract: 518,394. Change-giving mechanism. BRECKNELL, MUNRO & ROGERS (1928), Ltd., and DOLMAN, H. J. Sept. 23, 1938, No. 27700. [Class 27] A coin-container 1, from which the coins escape through orifices 4 into a shoot 20 leading to a hopper 15 of a change-giving machine, rests on four cambered rollers 6 ... 9 with its axis slightly inclined to the horizontal. Rollers 8 and 9 are driven from the motor 14 by belt gearing 12. The hopper 15 from which the change is delivered by a reciprocating pusher 21, is recharged automatically whenever the level of the coins falls sufficiently to no longer support the arm 16. The latter, by closing a contact 18, starts the motor to rotate the container and deliver a further supply of coin until the arm is raised again and the, re-opening of the contact stops the motor. ,The momentum of the moving parts continues to rotate the receptacle after the motor is cut-out and delivers additional coins until the hopper 15 is nearly filled. The container is lifted off the rollers and the lid 3 opened to replenish it, and in some cases may be oscillated instead of rotated. Specification 387,785 is referred to.

Filed: 1923-11-13
Abstract: 213,856. Hesselman, K. J. E. Nov. 13, 1923. Cylinders receiving liquid fuel. - The valve controlling injection of fuel is in the form of a disc 6; it is a sliding fit within a cylindrical cavity 16 formed in the lower end of a member 12, and is opened either by a cam or by the fuel pressure. The disc 6 is pressed on to a flat seating surrounding an injection channel 4 by a spring 11 mounted within a cup 10 in contact with the disc. When the member 12 lifts against the pressure of the spring 15, the valve disc is maintained against its seating by the spring 11 until lugs 9 on the cap 8 attached to the member 12 contact with the valve disc to lift it and thus permit the fuel injection. The pressure of the spring 15 is normally taken by lugs 81 on the lower end of the cap 8 which is so arranged that free access of the fuel to the cavity 16 is assured. The cup 10 may be omitted; and the upper plane surface of the disc 6 may be otherwise constructed.

Specified solvents are petroleum ether, benzene, toluene, cyclohexane, methylcyclohexane, chlorobenzene, methylene chloride, ethyl acetate, methanol, isopropyl alcohol, tert.-butyl alcohol, methyl ethyl ketone, liquid butane, liquid propane, liquid methyl chloride and mixtures.  The last three are liquids under the reaction conditions.  Suitable catalysts are diacetyl peroxide, dicaproyl peroxide, dibutyl peroxide, dilauryl peroxide, tert.-butyl hydroperoxide, alpha, alpha1-azodiisobutyric acid nitrile, admixed, if desired, with reducing agents such as salts of iron, titanium, nickel, and complex cobalt salts such as <FORM:0807112/IV (a)/1> The pH of the polymerizable mix is generally between 2 and 6. Vinyl esters mentioned are the acetate, propionate, butyrate, and benzoate. The copolymer can be hydrolysed to give free hydroxyl groups which can be subsequently cross-linked with polyfunctional compounds such as polyisocyanates, polyaldehydes, or polycarboxylic acids.  The copolymer may be made into films or foils, used as an impregnant for paper or textiles, or as an additive to other types of polythene. Dyestuffs may be printed on the copolymer.

The mixing chamber body 190 and cover 206 are detachably mounted on the gun body and retained by a pair of wing-nuts. The trigger 24 has a shoulder which actuates the motor stop and start air valve 104 which also admits air to a part 120 to start a metering and pumping apparatus which supplies the mixture components; there is also an adjustable air regulating valve 92 for controlling the motor speed. The trigger also, through a link 180 and yoke 178, 172 (Fig. 6) unlocks, after the motor valve 104 has opened, the valves 156, 158 controlling admission of accelerator and base material respectively to the mixing chamber. Being spring-loaded these valves, after actuation of the trigger, will not open until the pressure of the materials is sufficient to unseat them; they act also as check valves against reverse flow of material from the mixing chamber. Adjustment nuts 174, 176 are provided to adjust the inflow pressures of the components. An air line is connected to a passage in the mixing chamber body 190, see Fig. 4 (not shown), whereby compressed air may be admitted to the mixing chamber when making foams, there being a needle shut-off and adjustment valve in the member 190. The same line may also be used to admit solvent or a solvent-air mixture for purging the mixer.

The tubes 16 act to reduce the pulsations in the gas before it passes out of the chamber 7 through connections 10, and also the tubes 16 each form part of a device 12 for centrifugally separating contaminant particles from the gas. Each separator device Fig. 4, comprises a swirl chamber 15 surrounding the corresponding tube 16 and having a tangential inlet 19 for the gas. Separated particles fall downwardly through the open end of a separator tube 20 into a collecting chamber 14, and the cleaned gas passes upwardly through the tube 16 into the chamber 7 and thence to outlet connections 10. Particles collected in the chamber 14 are withdrawn as necessary through a sump 22. 23 are bracing means. Another embodiment (Fig. 3) is described; differing only in the arrangement of the inlet, outlet, and particle collecting chambers. Preferably the ratio of the aggregate cross-sectional area of the tubes 16 to the gas flow rate in cubic feet per minute is in the range from 0.0262 to 0.1375.
