Filed: 1929-10-03
Abstract: 344,807. Pasteurizing beer &c. NORMAN, P. W., 4, Mitcham Park, Mitcham, Surrey. Oct. 3, 1929, No. 30026. [Class 49.] In apparatus for pasteurizing beer and other liquids in bottles or like containers in which crates containing the bottles are passed in succession through preheating, pasteurizing and cooling tanks, a conveyer is provided for giving the crates a linear motion through the tanks together with means for simultaneously imparting a rotary motion to the crates. In one form, Figs. 1 and 2, the bottles are disposed in crates 7 which are drawn by a belt conveyer 1 through a preheating tank 11, a pasteunzing tank 12 and a cooling tank 13. The tanks 11, 13 are connected by a pipe 14 having means 15 for circulating the water or other liquid from one to the other in the direction opposite to that in which the bottles are moved, the liquid being returned from tank 11 to tank 13. The water may be kept at the pasteurizing temperature by applying steam inside or outside the tank. The steam supply may be thermostatically regulated. The conveyer 1 has pivot members 2 to which are attached rods 3 having at their other ends bearings 5 carrying trunnions 6 secured to the crates 7. Gear-wheels 8 are rigidly connected to the crates 7 and mesh with racks 9 running along the interior of the tanks 11, 12, 13. As the crates 7 are drawn bv the conveyer 1 through the tanks a clockwise rotation of the crates is obtained by the engagement of the gear wheels 8 with the racks 9. Two or more preheating and cooling tanks may be provided, the first preheating tank being connected to the last cooling tank and the second preheating tank to the first cooling tank, and so on. In another form, Fig. 3, pasteurized bottles are removed from the crates 7 and replaced by unpasteurized bottles when the conveyer 1 passes over a pulley 17. The crates descend through a chamber 11a where they are sprayed whilst rotating with water from a cooling tank 13, the water having been pumped to tank 13 from a tank 11b which with chamber 11a forms a preheating system. Part of the water from tank 13 returns directly to tank 11b. The pasteurizing system is formed by tanks 12a, 12c and a spray chamber 12b. The crates are rotated in all the treatment units.

Title: Dental filling package
Inventor: LEE HENRY L II
IPC: C08F20/16
Filed: 1969-06-13
Abstract: 1,268,115. Dental filling materials. JOHNSON & JOHNSON. 13 June, 1969 [14 June, 1968], No. 30149/69. Heading C3P. Packaged dental filling materials for preparing cured dental fillings comprise a two-part system, one of said parts being a paste consisting of a binder system comprising a colourless binder monomer which is a bisphenol A derivative having at least two terminal acrylate or methacrylate ester groups, at least 65% by weight of a finely divided filler and a free radical polymerization catalyst; and the other of said parts being a paste containing substantially the same monomer as in the first part, at least 65% by weight of a finely divided filler and an activator for said catalyst. Polymerization is initiated when the two packaged parts are blended together. The preferred binder monomer is that of the formula The viscosity of the monomer can be adjusted by diluting with another monomer such as methyl methacrylate or a glycol dimethacrylate, e.g. triethylene glycol dimethacrylate. Benzoyl peroxide is a suitable catalyst and the activator may be, for example, N,N.dimethyl.p-toluidine or p-toluenesulphinic acid. Preferred as fillers are inorganic materials such as fused silica, aluminium oxide, crystalline quartz and glass beads. The filler may be treated with a keying agent, e.g. an ethylenically unsaturated organosilane, to improve the bond between the polymerized binder and the filler particles. Optional components which may be added include inhibitors such as butylated hydroxy-toluene, U.V. absorbers such as 2-hydroxy-4-methoxy-benzophenone, and submicron particle material, e.g. hydrophobic submicron silica, to prevent possible slight separation between binder monomer and filler. Pigment can be included in one of the parts to obtain any desired colour shade; in the example unspecified organic dyes are used.

Title: Liquid mixture control apparatus
IPC: G01N11/08
Filed: 1951-12-27
Abstract: 707,930. Mixing appliances. TRIANGLE PACKAGE MACHINERY CO. Dec. 27, 1951 [Dec. 27, 1950], No. 30189/51. Class 86 In a method of maintaining a body of liquid mixture within a desired range of viscosity, a stream of mixture is continuously pumped through a pressure zone from which it returns to the liquid body, and mixture components which either increase or decrease the viscosity of the mixture are added to the mixture in response to the occurrence of pressures in said ,zone which are less than a predetermined lower pressure or are above a predetermined higher pressure, respectively. A constant volume pump 14 draws liquid adhesive from a tank 10 through a pipe 13 and delivers it to a high pressure chamber 15 from which it flows through a regulatable orifice 16 into a pipe 20 for return to the tank 10. The pressure in the chamber 15 is applied, by way of a device 27 which serves to damp out pressure pulsations produced by the pump 14, to a pair of pressure operated switches 38 and 39. The switch 38 operates when the pressure drops to a predetermined minimum and energizes a vibrator 25 which causes dry powdered adhesive to be advanced by a tray 24, into a shoot 22 down which flows a shallow layer of the liquid adhesive returning to the tank 10. The switch 39 is operated when the pressure in the chamber 15 rises to a predetermined maximum and energizes an electrically operated valve 40 to admit water into the inlet side of the pump 14. The size of the orifice 16 is controlled by manual means 18 so that the range of viscosities producing the required actuating pressures at the switches 38, 39 can be selected. A valve 43 is provided for withdrawal of adhesive as needed, the level of adhesive within the tank 10 being maintained above a set limit by a pressure operated switch 44, which is effective for its purpose by exercising control over the addition of dry adhesive. As an alternative to adding dry adhesive, concentrated liquid adhesive may be drawn in from a tank 45 under control of a valve 46 which responds to the actuation of the switch 38, or may be supplied into the return pipe 20 from a tank 97 by means of a pump 98 driven by a motor controlled by the switch 38. Thermostatic means may be provided to control the supply of heating and cooling medium to the tank 10, by which means a required temperature of the adhesive may be maintained.

Title: Separation of components of a predominantly gaseous stream
IPC: B01D53/00
Filed: 1966-07-08
Abstract: 1,103,130. Separation of components from gas mixtures by partial liquefaction. ESSO PRODUCTION RESEARCH GO. 8, July, 1966 [27, Aug., 1965], No. 30854/66. Heading B1B. [Also in Division F4] Components of relatively high condensation temperature are separated from a multicomponent gaseous stream, flowing at high pressure through pipe 1, by expanding the gas through nozzle 9 and divergent channel 26 whereby the gas stream acquires supersonic velocity with vibration and the temperature decreases so that the components of relatively high condensation temperature are liquefied in the form of droplets, and conducting the gas and entrained droplets through a curved passageway 37 bounded on one side by a porous wall 33, which may be formed of porous stainless steel. Owing to centrifugal action, the liquid droplets are ejected from the gas stream to the porous wall and pass through it, the liquid being collected in channels 35A, 35B .. 35F. The pores of wall 33 become nearly saturated with liquid so that very little gas can pass through. The gas is directed by. channel 37 to nozzle 51, where the gas is compressed before leaving through pipe 55. The apparatus is suitable for separating propane and butane from natural gas containing methane. The formation of liquids droplets in channel 26 may be enhanced by the application of a direct or alternating electric field by means of high-voltage electrodes 28. In a modified apparatus, sound waves are induced in the gas flowing to nozzle 9 by means of a whistle. The liquid condensates in the channels 35 are conducted to a header via back-pressure regulators which maintain a uniform pressure drop across the porous wall 33. The combined condensate in the header is led to a stabilizer to separate out any low condensation temperature components, e.g. methane and ethane. The liquid from the base of the stabilizer, the gas from the top, and the depleted gas in pipe 55 are separately withdrawn from the system via heat exchangers which cool the mixed gas stream being fed into the system.
