Title: Production of egg white substitute from whey
IPC: A23J3/08
Filed: 1976-04-08
Abstract: 1487169 Separating proteins STAUFFER CHEMICAL CO 8 April 1976 [30 May 1975] 14305/76 Heading C3H [Also in Division A2] Liquid whey from a cheese or vegetable source is treated with sodium lauryl sulphate to precipitate the protein therefrom by forming a complex, and the SLS content of the complex is then reduced to not higher than 1À0% to give an egg white substitute. The whey may be acid or sweet cheese whey, or soya, cotton seed, sesame seed, rape seed, sunflower seed, mung bean, Great Northern bean, or coconut whey, and may be in the form of a protein concentrate which has been partially delactosed, e.g. by reverse osmosis, ultrafiltration, gel filtration or by alcohol precipitation. Fat may be removed either before or during the SLS treatment by washing and centrifuging. The SLS may be used in powder or solution form. If cheese whey is treated 0À1-0À5% W./v. of SLS should be used at 10-45‹ C. and pH 3-5. In the case of vegetable whey 0À3-0À6 parts SLS per part dry protein is added at 20-40‹ C. and pH below 5. The SLS may be removed by means of an ion exchange resin in the hydroxy form, by treatment with barium chloride or acetone, or by dialysis. 0À1 to 5% of a Ca, Mg or Al compound may be added to the product to improve its heat sensitivity. The product is then used as an egg white substitute in meringue preparations, together with sugar and water, and dried egg albumen.

Title: Method for the electrolytic preparation or concentration of heavy water
IPC: C01B5/02
Filed: 1944-07-27
Abstract: 580,791. Electrolytic concentration of heavy water. TRONSTAD, L. July 27, 1944, No. 14350. [Class 41] The efficiency of the electrolytic concentration of heavy water in ordinary water is increased by using a cooled cathode and causing the incoming feed water to flow along knife edges or other surfaces of high current density on the cathode before mixing with the bulk of the electrolyte. The cathode, at which the preferential liberation of ordinary hydrogen takes place, comprises upper and lower hollow rings 5, 6, joined by four tubes 7 having knife edges 8 at which the current concentrates causing an increased separation efficiency without appreciably increasing the cell resistance. Circulation of cooling water through tubes 16, 17, which also carry the current supplied to an insulated lid 4, cools the electrolyte immediately surrounding the cathode, again improving the efficiency without appreciably increasing the electrical loss. The perforated cylindrical anode 2 is fixed inside the cell tank 1 which acts as the positive terminal of the cell. An asbestos-cloth cylindrical diaphragm 9 is suspended from an insulated funnel 10 and serves to separate the electrolytic gases. The feed water from tubes 19 runs up the edge 8 of the cathode being carried largely by the hydrogen evolved, and runs down the funnel 15 to boiler 23 where part of the water enriched in deuterium is evaporated and passes to a condenser at 24, the remaining water and deuterium returning to the cell by tube 25.

Class 39(2) An incandecent lamp has a coiled coil tungsten filament of length greater than the diameter of the neck of the lamp bulb, the filament being in one straight line at an angle with the lamp axis of between 20 degrees and 70 degrees and being positioned at about the centre of the bulbous portion of the lamp bulb. Preferably the angle is between 30 degrees and 60 degrees, and the nominal lamp rating is between 150 and 1000 watts and the voltage between 100 and 250 volts. Preferably, not more than two intermediate supports for the filament are used. The lamp may have two independently connected filaments arranged parallel to one another or at an angle of between 40 degrees and 140 degrees, preferably between 60 degrees and 120 degrees. Part of the bulb may be formed as a paraboloid of revolution and coated with a reflecting layer, one filament being at the focus of the paraboloid. In the form shown in Fig. 1, the filament 9 is mounted at 40 degrees to the lamp axis on leading-in wires 3 of nickel plated iron inside the bulb, copper clad wires 4 in the pinch 2 and copper wires 5 secured to the base shell 6 and eyelet 7. Two intermediate supports 10 of molybdenum are provided. Two filaments in parallel planes on opposite sides of the lamp axis may be provided for use together or separately, one being rated for 300 watts and having two intermediate supports and the other for 150 watts and having a single intermediate support. A disc 11 of mica, aluminium vapourized is provided to shield the seal and base from excessive heat. The bulb 29, Fig. 4, is designed as a paraboloid of revolution and coated with a reflecting layer 30 of silver or aluminium or of a suspended insulator of high reflectivity such as titanium dioxide or aluminium oxide. Two filaments 33, 34 are supported in a cross pinch 31 at right angles to one another and inclined at 45 degrees to the lamp axis. The centre S1 of filament 33 nearly coincides with the focus of the paraboloid while the centre S2 of the filament 34 is displaced a few millimeters from the focus in a direction away from the vertex of the paraboloid. The filament 33 provides a spotlight and the filament 34 is used for floodlighting. In a further modification, the two filaments are parallel to one another at an angle to the lamp axis, the centre of one filament lying at the focus of the paraboloid and the centre of the other being displaced from the focus in a direction along the axis. It is stated that, in lamps having a gas filling at a pressure exceeding atmospheric pressure, additives such as hydrogen or iodine may be included in addition to argon or krypton and nitrogen.

Patent GB-154732-A (GB)
Abstract: 154,732. Tatton, J. Sept. 13, 1919 Stop-motions.-A stop motion of the drop-needle or detector-wire type is actuated electrically when a warp thread breaks or fails, instead of being actuated mechanically as described in Specification 134,137. The warps 6 normally support drop wires 8 loosely arranged within the slots of a bar 4. Should a warp 6 break or fail, the corresponding wire 8 drops and bridges the space between bars 9, 10, thus completing the circuit. The bar 10 is insulated from the bar 4. An clectro-magnet 12 within a box 11 is thus caused to attract a trigger 14 against the pull of a spring 16, and release the projecting arm 20 of a vertical bolt 18. A spring 19 then slides the bolt 18 upwards, and the lower end breaks the circuit by operating a switch 29 while the upper end lifts a lever out of a notch in the belt shifter bar and enables a spring to stop the machine by shifting the belt on to the loose pulley. The dropped wire 8 is recovered by turning the bar 9 about its pivot 9<a> away from the bar 10 when the wire passes through the space between the lower ends of the bars 9, 10.

Batteries B1, B2 are charged from an A.C. source P1 by way of a transformer T1 and bridge rectifier D1-D4. Initially the charging current is high due to a resistor R1 in series with the primary winding 4 of the transformer being short circuited by a contact S1 of a thermally operated switch, the operative element 12 of which is associated with the transformer T1. As the batteries B1, B2 charge at the high rate the temperature of the transformer increases until, at a predetermined temperature, the element 12 causes the contact S1 to open so inserting the resistor R1 into the primary circuit of the transformer to reduce the charging current to a low value. Numerous embodiments are described in which the switch S1 is associated with a resistor in series with the secondary winding; in which the switch is arranged across a number of the turns of the primary or the secondary winding; in which the secondary winding is divided into two windings with each secondary circuit provided with a switch S1 operable by a common element 12, in which the element 12 is responsive to the heat generated by a resistor in the primary circuit or in which the switch is replaced by a thermistor responsive to the heat generated by the transformer.
