Abstract: In order to preserve foods, examplified by meat and fish, e.g slabs of bacon and ham, sides of beef, poultry, lobsters and whale products, fruit, e.g. oranges, pineapples and bananas, vegetables, e.g. egg plant, squash and avocados, edible oils and fats, e.g. linseed, menhaden, cod liver, castor, olive, rapeseed, coconut, palm, corn, sesame, peanut and babassu oils, butter, lard, beef tallow and hydrogenate oils and fats, against oxidative deterioration, the food is treated with butylated hydroxyanisole and a 2, 4, 6-trialkylphenol in the proportion 30 to 70/70 to 30.  The trialkyl phenol employed according to the examples is 2, 6-di-tertiary butyl-4-methylphenol. A mixture of the butylated hydroxyanisole and trialkylphenol is preferably employed in an amount from 0,001 to 0,1 per cent by weight of the food.  Such a mixture may be injected into or sprayed on the food, or the food may be soaked in the mixture, and for these modes of application the mixture may be liquefied by heating, may be dissolved in a suitable solvent, e.g. propylene glycol or glycerol, or may be dispersed in water with the aid of an emulsifying agent such as mannitan, mannide or sorbitan monolaurate, monooleate or monopalmitate.  The mixture may be incorporated in food packaging materials e.g. in the wax of wax coated paper.  Known fat antioxidants, e.g. nordihydroguaiaretic acid, 5-hydroxycoumarin and propyl gallate, and substances which act as synergists or deactivators of metals which catalyze oxidation, e.g. citric, phosphoric and ascorbic acids, may also be incorporated.

Patent GB-441502-A (GB)
Title: Improvements in or relating to methods of coating metal and the coated metal resulting therefrom
IPC: C25D5/34
Filed: 1934-07-24
Abstract: The resistance to corrosion of metals, e.g., wires for use as tire bead reinforcements is increased by applying molten cadmium or alloys thereof to form a resistant coating, and then applying an outer coating of cadmium zinc, or alloys thereof by electrolysis.  The first coating may be wiped to provide a relatively thin coating before the outer coating is applied. Alternatively molten zinc or zinc alloys may be applied to form the undercoating which is then wiped and covered with an outer coating of cadmium or cadmium alloys by electrolysis.  To increase the adhesiveness of the metal to rubber a further coat of copper or an alloy of copper and antimony may be applied, or copper may be applied first and then covered with antimony by electrolysis. The undercoat of zinc, cadmium, or their alloys may be applied by hot dipping or by any other method in which molten metal is applied.

Patent GB-912467-A (GB)
Title: Improvements in or relating to heat exchangers
IPC: F28F3/08
Filed: 1960-06-22
Abstract: Relates to a heat exchanger particularly for the concentration by evaporation, of milk, salt solutions, fruit juices, or for use in the production of fresh water by evaporation from sea water, and comprising an assembly of parallel plates defining two sets of interspaces with two pairs of main ports formed by aligned apertures in the plates one pair communicating with each set of interspaces. According to the invention at least one additional port is formed in each plate, said one or each additional port communicating with one set of interspaces and through said set with a pair of main ports such that a heat exchange medium flows through said set in two parallel connected streams between the said additional ports or at least one of said additional ports and the communicating pair of main ports which are approximately minor symmetrical with respect to the additional port or ports.  The plates may be of any suitable shape such as oval or (as shown) rectangular.  In the case of a liquid which is heated and partially vapourized in one set of interspaces (Fig. 5, not shown), the liquid may enter an interspace through the small additional port and the subsequent vapour be passed from the space through the main ports. <PICT:0912467/III/1> <PICT:0912467/III/2> <PICT:0912467/III/3> <PICT:0912467/III/4> When a vapour is to be cooled in one set of interspaces the vapour may enter an interspace through the main ports and condensate be discharged through the additional port.  The arrows in Fig. 3 show the path of such a vapour entering the space enclosed by the packing ring 6 via the ports 1 and 2, the condensate flowing out through the additional port 5.  Air or uncondensed gas is discharged through the hole 9. The flow through the other set of interspaces may be conventional, i.e. from one main (inlet) port to the other main (outlet) port (Fig. 4, not shown) or it may be such as to provide parallel-connected streams as described above. In Fig. 7 cooling medium enters through the port 11 and leaves through the ports 3 and 4, while in Fig. 8 the heating medium enters through ports 1 and 2, the condensate leaving through the port 10.  Fig. 12 shows a heat exchanger, built up from plates of the kind illustrated in Figs. 7 and 8, in which steam enters through the pipe 25 its condensate leaving through the pipe 26. The cooler medium is supplied through the pipe 27 leaving after vaporization through the outlet pipes 28 which opens into a collecting container 30.  Steam is discharged through an outlet 31 and liquid through an outlet 32.  If this liquid needs further concentration it is fed back through the pipe 33.  Fig. 13 shows a combination of such heat exchangers 34, 35, 36, 37, 38 and 39. Steam is supplied through the inlet 40 and liquid to be heated and evaporated through inlet 41.  Through outlets 42 and 43 a mixture of steam and liquid discharges into a collecting tank 44 where the two phases are separated, steam being led off through the pipe 45 and liquid through pipes 46 or 47 to be further concentrated.

Title: Stopper for flask
IPC: B65D51/00
Filed: 1949-08-23
Abstract: 659,602. Stoppers. RANE, L. Aug. 23, 1949, No. 21897. Convention date, Sept. 1, 1948. '[Class 125(iii)] [Also in Group VI] A flask stopper has a tapered body of soft vulcanized rubber or the like with a duct 20 extending therethrough in an axial direction with its outer end 26 flared to form a substantially conical valve seating; a valve member 30 which has a head 32 shaped to seat in the valve seating and a dependent shank 34 which enters the duct and has radial projections 36 towards the inner end which bear against the duct wall, the arrangement being such that when the stopper is wedged in the mouth 12 of the flask with the valve closed contraction of the duct causes the valve to be gripped and held in the closed position until the pressure in the flask exceeds the external pressure whereupon there is a. sufficient relative resilient yield between the parts to permit escape of gas &c. from the flask. Preferably the stopper has an integral skirt 14 of considerable length to embrace the bottle mouth, and a concentric rib 18 on the top with an inner diameter substantially equal to the maximum diameter of the stopper. The duct 20 has a constriction 28, immediately below the conical part 26, in which the shank 34 of the valve 30 fits loosely. The valve may have a finger tab 38. A number of holes 22, 24 also extend through the stopper, each having an upper conically flared orifice 40 and a constricted portion 42, and each hole is fitted with a soft rubber plug 44 having a conical end 46 to seat in the orifice 40, a shank 48 to fit in the portion 42, an enlarged lower end 50, and an axial bore 52 extending from the lower end to near the upper end. The duct 20 may be continued downwardly by a tubular extension 60 provided with small holes 62. A vent tube 64 is usually fitted into one of the holes 22, 24. The stopper may form part of a blood transfusion &c. apparatus, the flask being filled and inverted, the valve 30 removed and a tube thrust in the outer end of duct 20. The extension 60 acts as a strainer. An air vent is provided by thrusting a hollow needle through one of the slugs 44 into the bore 52, the punctured plug being replaced after use. When the flask is heated to sterilize it and its contents the internal pressure lifts the valve 32 to permit escape of gas &c. the valve then being held on its seat by the elasticity of the parts, and later by the outer pressure when the inner, pressure drops. In the example shown in Fig. 3, the duct 20 extends through the stopper, but holes 70, 72 stop short of the top leaving integral diaphragms 74, 76. The vacuum in the flask forms slight depressions at 74, 76 indicating where the needle should be thrust and these parts preferably contain a high percentage of rubber gum so that they are self-sealing and may be punctured a number of times.

Abstract: 597,781. Facilitating changing speed; claw clutches. CROSSLEY MOTORS, Ltd., and OWEN, W. Aug. 27, 1945, No. 21924. [Class 80 (ii)] To permit gear shifts with both engine and vehicle in motion in a conventional change-speed gear driven by a fluid coupling or torque converter, the latter drives the input shaft of the change-speed gear through a frictionally synchronised claw clutch e, f which can only be disengaged when the accelerator pedal is released, so that a shift can only be made when the engine is idling. The clutch is operated with or without fluid pressure assistance through a rockshaft p which can only be turned for disengagement when, by release of the accelerator pedal t a recess u in a rod s linked thereto registers with a recess (not shown in Fig. 3) in the rockshaft p. In operation a pedal secured to the rockshaft p is fully depressed first to disengage the axially toothed claw-clutch members e, f, then to engage friction cones j, d, on the clutch members to replace the positive drive by a frictional one. The pedal is then eased intermittently until the change-speed gear can be neutralised and a shift made, whereupon the pedal is released to permit synchronised re - engagement of the claw clutch.
