Abstract: 1347439 Spray dried egg albumen STAUFFER CHEMICAL CO 12 Dec 1972 [20 Dec 1971] 57260/71 Headings A2B and A2D Spray dried egg albumen is prepared by adding 0.05-2.0% of alkali metal (including ammonium) phosphate to the liquid albumen, and then spray drying the albumen. The preferred amount of phosphate is 0.1-0.7%. The phosphate may be dipotassium, disodium or diammonium phosphate, polyphosphate having an average chain length of 2-40, e.g. sodium or ammonium pyrophosphate, sodium tripolyphosphate, potassium pyrophosphate, sodium hexametaphosphate having a chain length of 6-15, potassium tripolyphosphate, sodium tetrapolyphosphate, potassium pentapolyphosphate, sodium octapolyphosphate, glassy polyphosphates having a chain length of up to 40, cyclic polyphosphates such as potassium trimetaphosphate and sodium tetrametaphosphate, or mixtures thereof. The glucose content of the albumen may be reduced before spray drying by bacterial or yeast fermentation, or by the use of glucose oxidase enzyme at pH 7 and 5-13C with the addition of hydrogen peroxide over 10-24 hours. The albumen may be pasteurised either by adding hydrogen peroxide and heating to 125-140F for at least one minute before spray drying, or by storage at 120-135F for 4-15 days when packaged after spray drying, The albumen is spray dried at pH 6-9, preferably pH 6.8-7.2, and is adjusted to this value by adding citric, lactic, fumaric, sulphuric, hydrochloric or phosphoric acid. About 0.01% of sodium lauryl sulphate may be added with the phosphate as a whipping agent. The spray dried albumen can be reconstituted and incorporated in batter, e.g. for angel food cakes. The addition of phosphate to the albumen is particularly effective if the albumen is contaminated with yolk.

Filed: 1974-03-07
Abstract: 1464559 Hydraulic couplings DYNAIR Ltd 7 March 1974 [24 May 1973] 58885/73 Heading F2W In a viscous shear coupling for a motor vehicle fan drive wherein a driving casing 16 or 71 closely surrounds a driven disc 30 or 77 which is connected by a hub 12 or 78 to fan blades 9 or 80, a scoop tube or impact pump continuously pumps liquid from a working space between the disc and casing to a reservoir (32, 33) or 96 within the disc or hub and liquid is returned to the working space through a valve 40 or 95 under the control of a temperature responsive element (6) or 85. The driving casing 16 or 71 carries cooling fins 18 or 74 and the fan blades 9 or 80 are resiliently mounted on the hub 12 or 78. In Fig. 1 the reservoir (32, 33) Fig. 2 (not shown) is formed within the disc 30 and a scoop tube (36) pumps liquid from the working space into the reservoir. Radial spokes 27 within the reservoir house radially slidable valve spools 40 which are biased radially inward by springs 43 to an open position in which liquid from the reservoir flows freely to the working space for maximum torque transmission. When the engine water cooling temperature drops below a predetermined value a temperature sensitivelement (6) Fig. 3 (not shown) opens a valve (7) to supply compressed air from a pump or reservoir (8) to a chamber 62. The pressure air in the chamber 62 acts through a piston 51, rod 52 and thrust bearing 53 to pivot a bell crank 55 clockwise and thus urge the valve spool 40 radially outward to a position in which the flow of liquid to the working space is reduced. The reduction of liquid in the working space causes a drop in the fan speed. The valve 40 is additionally responsive to the fan speed. When the speed of the fan attains a predetermined value the valve spool 40 is moved radially outwardly by centrifugal force to maintain the fan at a predetermined maximum speed. In Fig. 6 a bimetal temperature responsive element 85 acts directly through a pin 87 on the valve element 95 against the bias of a spring 99. When the temperature of the air leaving a radiator exceeds a predetermined value the temperature sensitive element 85 moves to the position shown in which the valve 95 opens to permit liquid to flow from the reservoir 96 through duets 100, 101 to the working space. A scoop tube (92) Fig. 5 (not shown) continuously pumps liquid from the working space through radial ducts in the disc 77 to the reservoir 96. In Figs. 7-9 (not shown) an impact pump (110) continuously pumps liquid through radial ducts in the disc to the reservoir and the temperature responsive bi-metallic element acts through a rod on a valve element (112) which is pivoted to the driven disc.

Filed: 1972-12-29
Abstract: 1407639 lonization chambers PREUSSAG AG FEUERSCHUTZ 29 Dec 1972 [30 Dec 1971 23 June 1972] 60021/73 Heading H1D The shape and dimensions of the electrodes of an ionization fire detector are such that airflow through the detector, due to ambient air movements, becomes turbulent in the region of a certain critical velocity. As shown, a foraminous anode 12 is arranged opposite a cathode 10 which is provided with a recess 20 facing the anode. External air movements (flow lines 46) promote internal airflow between inlet aperture 34 and outlet aperture 36 (flow line 40). Below a certain value of ambient air velocity, the airflow between the electrodes is laminar and is of insufficient magnitude compared with the velocity of ions produced by radioactive source 18 to remove these ions from the inter-electrode space. The position and dimensions of the cathode recess 20 are chosen to produce turbulence as the ambient air velocity increases, whereby the inter-electrode airflow becomes less efficient and removal of ions is reduced below what would normally be expected. The Specification gives examples of air and ion velocities, and of the principle dimensions of an exemplary embodiment. Modifications are described (Figs. 2, 3, 4, not shown) in which the recess 20 is in the form of a spherical segment, a shallow cone and a truncated cone. In a further modification (Fig. 5, not shown), the aperture 36 is eliminated and air flows in at one aperture 34 and out at another. In addition to source 18, further sources 44 may be located near the air inlets.

Filed: 1968-12-19
Abstract: 1,197,269. Incinerators. MIDLAND-ROSS CORP. 19 Dec., 1968 [19 Dec., 1967], No. 60446/68. Heading F4B. A refuse incinerator comprises a lower charging chamber 5 and an upper smoke consuming chamber 6 interconnected by a flue 7. Combustion air is supplied to the lower chamber 5 through perforated hearth ducts 24, extending the length of the chamber and embedded in a refractory lining, excess air ducts 26 extending through the rear wall, and an annular air dispenser 19 surrounding the charging aperture of the lower chamber. Both air and fuel, or air alone may be supplied to the upper chamber 6 through a burner 33 in its front wall. In operation, valves 41 and 42 in line 35 are preset to continuously pass fixed quantities of air from blower 38 to the burner 33 and the annular air dispenser 19 respectively. The air supply through lines 45 and 46 to the ducts 26 and 24, and the fuel supply through line 36 to the main burner 33 and a pilot burner 52 are then regulated by an automatic electrical control system including solenoid valves 43, 44, 48 and 49, in response to the upper and lower chamber temperatures, as measured by thermocouples 61 and 62 respectively. After initial charging of the lower chamber 5 with refuse, burner 33 is supplied with fuel and lit. At an upper chamber temperature of 600 F. air is also supplied through hearth ducts 24 in the lower chamber 5 to help in combustion of the refuse. At an upper chamber temperature of 1400 F. the fuel supply to burner 33 is shut off, whilst additional combustion air is fed to excess air ducts 26. This is the optimum incinerating condition, during which further charges of refuse may be added if desired. Should the lower chamber temperature exceed 1950 F. at any time, an overriding control prevents fuel flowing to the burner 33 and cuts off the air supply to hearth ducts 24 until the temperature falls. A warning light indicates that in this condition the incinerator should not be recharged. During recharging of the incinerator the electrical control system again overrides the normal temperature control of the fuel and air supplies, so that the main burner 33 is kept on whilst the air supplies to the hearth and excess air ducts 24 and 26 are kept off. The control system can also effect automatic shut down of the incinerator by overriding of the normal temperature control in which case the burner 33 is shut off, and when the lower chamber temperature falls below 900 F. all the air supplies are cut off by stopping the blower 38. The front end of chamber 5 is formed as a detachable clean out door 14 which is secured by hinges and clamps (Fig. 4, not shown) to the front end of the chamber to allow access to its interior and to the hearth tubes 24. A central charging aperture in door 14 is covered by charging door 15 which is similarly secured to the door 14. The annular air dispenser 19 surrounding this charging aperture produces a conical curtain of air (Fig. 3, not shown) so preventing smoke or fire particles escaping from the chamber, during refuse charging.
