Title: Method for stabilizing sterile milk products against gelation
Inventor: JNR AUBREY P STEWART
IPC: B01J39/04
Filed: 1957-08-13
Abstract: A sterile milk such as evaporated milk, whole milk, or cream, free from age-thickening, is produced by subjecting the milk to high-temperature, short-time sterilization, such as at 260 - 310 DEG F. for up to 5 minutes, and thereafter adjusting the salt balance of the sterilized product as by relatively increasing its divalent metal (calcium) ion concentration with respect to the monovalent metal (sodium and potassium) ion concentration. Sterilized, homogenised milk may be added to a can containing sterilized ion-exchange material and the can sealed, or the milk may be sterilized in a sealed can containing a liner of ion-exchange material coated with a substance which prevents the salt balance adjustment prior to and during sterilization.  In cases where sodium citrate or sodium phosphate has been added to the milk prior to sterilization to stabilize the milk against heat coagulation, a larger amount of the ion-exchange material should be employed.  In an example, sterilized evaporated milk was treated with 0,4% by weight of the milk of a strong acid cation polystyrene resin exchanger which in the sodium form had been treated with 15,1 g. anhydrous calcium chloride dissolved in 100 ml. distilled water per 100 ml. tamped volume of resin.

Abstract: 299,166. Hancock, L. J. Sept. 28, 1927. Perjorating and dividing by fusion.-In a blowpipe apparatus for cutting metals, the tracer or propelling wheel is geared to an air or like motor driven by the cutting oxygen in passing to the burner orifice. Mixed oxygen and gas for preheating purposes pass from the mixing chamber 3 to the burner 5 by way of the tube 4. Cutting oxygen passes through a pipe 6 containing a shutoff valve 7, and before reaching the burner passes through a port 11 in a gas-tight cylinder 10 containing a multi-bladed wheel 9, which is thereby rotated. The shaft of the wheel is connected by spur gear 13, 14 and worm gear 15, 16 to a shaft 17 contained in a tube 24 forming part of the cover-plate 22 and furnished with a gland 25. A worm 18 on the shaft 17 rotates a worm wheel on the shaft of the tracer wheel 21, which is mounted in a carrier 28 having a shank 27 which is vertically movable in brackets 26 on the tube 24. Part of the cutting oxygen may be byepassed by a valve 30 through a port 34 so as to regulate the speed of the tracer, or a brake may be used for this purpose. The apparatus may be guided mechanically or by a handle 35 or may be mounted on machines such as described in Specifications 243,816 and 298.885, or machines in which the tracer is mounted on one arm of a carrier and the burner on the other end.

Title: A system for imparting movement to an ionizable dielectric fluid medium
Inventor: BROWN THOMAS TOWNSEND
IPC: H02N11/00
Filed: 1969-05-21
Abstract: 1,274,875. Loudspeakers. GUIDANCE TECHNOLOGY Inc. 21 May, 1969- No. 25793/69. Heading H4J. [Also in Divisions H1 and H2] A system for importing movement to an ionizable dielectric fluid medium comprises a pair of spaced electrodes with a D.C. source connected across them and a control electrode located between them, the electrodes being immersed in the fluid and constructed so that the fluid can flow through them. In the embodiment shown in Fig. 1, the rate of flow of an ionizable, dielectric fluid produced by the application of a high D.C. voltage to electrodes 11, 13 is controlled by varying the electrostatic potential of the control electrode 12. The electrode 11  is in the form of a wire grid and electrode 13 comprises a set of parallel plates the combined surface area of which is greater than that of electrode 11. The control electrode 12 also comprises a wire grid having a surface area between those of electrodes 11, 13. The emissivity of the electrodes 11, 13 may be improved by coating them e.g. with caesium, barium chloride, thorium oxide or radioactive materials. Alternatively the electrodes may be heated. For example, electrode 11 may be heated through a step-down transformer 19 and the plates 13a of electrode 11 may incorporate heating elements connected to a suitable power supply. The D.C. potential applied to the control electrode may be modulated by an A.C. signal so that pressure waves are produced in the dielectric fluid. The signal may be applied through a transformer (23), Fig. 4 (not, shown), in series with electrode 12 or through a, single stage pre-amplifier (25), Fig. 5 (not shown). In these cases the devices may function as electro-acoustic transducers. Fig. 6 shows a loudspeaker utilizing a pair of devices according to the invention in push-pull. A common anode electrode 11 is located between a pair of cathode electrodes 13 and has a pair of control electrodes 12 disposed on opposite sides thereof to which the modulating signal is applied either through a transformer 33 or through a pre-amplifier stage comprising a pair of triodes in push-pull, Fig. 6 (not shown).

Filed: 1929-08-26
Abstract: 318,250. Soc. des Usines Chimiques . Rhone-Poulenc. Aug. 31, 1928, [Convention date]. Indiarubber threads and sheets.-Films, ribbons and like products are prepared from coagulable solutions by causing a film of the solution to be produced, by surface tension, between supports comprising two or more threads, wires, or plates, and coagulating the film with a liquid or gaseous medium. The supports may be retained in the finished film, and in this event they may be natural or artificial silk threads or thin metal wires, or may have the same composition as the film; in making cinematograph films, the supports may be tapes which may be perforated so as to serve for propelling the film. Alternatively, the supports may be separated from the coagulated films, for instance by cutting or dissolving. Suitable initial materials are solutions of gelatin, shellac, india-rubber, and certain mineral compounds, and any desired additions may be made to the materials. As shown in Fig. 1, support wires 4, 5 pass through housings in a narrow rectangular die 3 to which solution is supplied by a pump 2. The film formed between the wires is carried down through a drying chamber 10 connected to a condenser 13 for the recovery of solvent. A jacket 17 is provided to prevent choking of the die, and, to assist the initial formation of the film, a thread or plate 15 forming a bridge is placed against the wires near the die. The finished film and the wires are wound on a drum 12. In the form shown in Fig. 2, the endless wires 3, 4 pass upwardly through a trough 18 containing the solution, and the film is carried through a drying chamber 8 to a cutting device 16 which removes the film from the wires. The wires are guided by rollers 7 and 10 .. 15. and the film is wound on a roller 17. A series of heating jackets may be provided if it is desired to dry the film gradually. By using supports in more than one plane, products of circular, star-shaped or other cross-section can be made.
