Title: A process and apparatus for the manufacture of tubular products particularly suitable for use as artificial sausage skins
IPC: A22C13/00
Filed: 1938-04-05
Abstract: 509,810. Extruding artificial sausage skins &c. BECKER, O. W., AHRENS, R., and HAGANDER, J. April 5, 1938, No. 10461. [Class 87 (ii)] Tubular products, such as artificial sausage skins, are produced by extruding swollen fibrous masses, preferably of animal origin, through stationary annular nozzles of such length that partial deswelling of the masses takes place and deflecting the fibres while they are in the nozzles. The nozzle comprises a cylindrical casing 1 in which a hollow core 2 is disposed. The material is supplied through tubes 3 and compressed air is supplied through the space 6 to distend the tubular product. The annular bore may be of uniform cross-section as at 20 or it may be of increasing cross-section as at 22. Helical grooves 21 are provided on the parts 1 or 2 to deflect the fibres and grooves may be provided on both parts with the helices arranged in opposite senses. The grooves need not extend to the outlet of the nozzle. In a modification, Fig. 7, the deflecting elements comprise bores arranged in two groups A, B in a detachable ring 10. The two groups are inclined in opposite senses to produce a crossing of the fibres. The ring 10 may also be of conical form. In a further modification, Fig. 11, the bores may be formed on the inner and outer surfaces of two conical elements 15, 14. As shown in Fig. 12, the deflection of the fibres may be produced by annular grooves 16 and ribs 17 which produce vortex movements in the mass. The nozzles may be 300 to 600 mms. in length and the material may be extruded under a pressure of 80 to 300 atmospheres. Specification 429,040 is referred to.

Filed: 1923-04-17
Abstract: 219,084. Wiegand, E. L. April 17, 1923. Binding-posts and terminals; couplings.- A terminal for an electric conductor, such as a resistance element, comprises a body of malleable material with a pair of transverse abutments which are moved together on applying pressure in a longitudinal direction to deform the body and bring the abutments into clamping relation with a conductor placed between them. The terminal may have a screwed bore to take a wire or securing screw. The abutments may be of hexagonal or other contour to prevent the rotation of the terminal in a medium in which it is embedded. Figs. 4 and 5 show a terminal 1 with integral flanges 2, 3 and a circumferential groove between them to take a flat conductor 10 and Figs. 6 and 7 a terminal having a loose washer 3a with a recessed end into which the end of the terminal 1 is pressed in securing the conductor. The terminal is preferably composed of material softer than the conductor, for example nickel, monel metal or any alloy of brass with nickel up to 20 per cent is used with the usual nickel-chromium resistor conductor.

Abstract: 1,245,169. Iron oxide. PFIZER Inc. 27 Feb., 1969 [13 Nov., 1968], No. 10681/69. Heading C1A. High purity ferric oxide is prepared by cultivating an iron oxide bacterium under aerobic conditions in the presence of elemental iron, ferrous iron, and "ferrous sulphate" equivalent to at least one grain per litre of ferrous iron, at a pH from 2À2-3 and a temperature of 15-40‹ C., thereby precipitating hydrous ferric oxide. The "ferrous sulphate" is defined as anhydrous ferrous sulphate copperas, technical FeSO 4 .7H 2 O, or the complexes such as FeSO 4 .(NH 4 ) 2 SO 4 .6H 2 O and FeSO 4 .K 2 SO 4 . To the reaction may be added ferric hydroxide, yellow ferric hydroxide or red ferric oxide as seed for the hydrous ferric oxide. The preferred embodiment is Thiobacillus ferrooxidans as bacterium, copperas as "ferrous sulphate" with a ferrous iron concentration of 5-6 gms. per litre and a pH of 2À6-2À8. The process may be made continuous by the continuous or periodic addition of elemental iron and "ferrous sulphate" and the continuous or periodic removal of the hydrous ferric oxide containing liquor from which the hydrous ferric oxide is separated, to which additional nutrients are added and which is recycled to the reaction stage. The aqueous medium in which the bacterium is cultivated should also contain a source of nitrogen either in the form of ammonium ions or nitrate ions along with other inorganic salts. After separation the hydrous ferric oxide may be calcined at preferably above about 650‹ C.

Abstract: 710,418. Discharge lamps. GENERAL ELECTRIC CO., Ltd., and BELL, J. May 12, 1952 [May 11, 1951], No. 11229/51. Class 39(1) A gas-filled electric discharge device having a filling at least partly of hydrogen and provided with a sealed container having within it a substance which evolves hydrogen on heating, the arrangement being such that in operation at the normal maximum loading hydrogen is automatically liberated from the container when the pressure of the filling tends to fall due to " clean-up " of hydrogen, is characterized by the provision of an auxiliary heater arranged so that during operation of the device at less than the normal maximum loading the temperature of the container can be maintained at the same value that it reaches under normal maximum loading conditions. Fig. 1 shows a high-intensity lamp comprising a cathode 1 surrounded by a nickel cylinder 2 closed at each end and a semi-cylindrical anode 3 provided with cooling pins 4. The electrodes are contained in a glass envelope filled with hydrogen at 5 mms. pressure and provided with a quartz window 6 sealed to it by wax, the seal being cooled by water flowing through tubes 8 and 9. The cylinder 2 is supported by nickel bands 22 from a nickel band 23 round the foot, and the anode 3 is supported by its leads at the lower end and from the cylinder 2 at the upper end. The anode and the cylinder 2 are provided with slits 10, 11 to allow the light to pass through to the window. A sealed nickel tube 17 containing zirconium hydride is attached to the outer surface of the anode and a heater 18 is provided, these two being enclosed in a nickel semi-cylinder (not shown). In operation at the normal maximum loading, the tube 17 is heated 'sufficiently by the anode to release hydrogen and maintain the pressure of the hydrogen filling, the nickel tube being permeable to hydrogen at high temperatures; in operation at reduced loading the heating by the anode is insufficient and the auxiliary heater 18 is energized to maintain the pressure. The tube 17 may 'be heated by direct thermal radiation from the anode instead of being secured to it, or it may be constructed so that the anode forms part of it; instead of being of nickel it may be partly or wholly of copper, iron or palladium, and it may contain hydrides of titanium, tantalum, vanadium or thorium instead of zirconium. According to the Provisional Specification the tube 17 may contain hydrogen at a pressure greater than the pressure of the filling. Specification 675,097 is referred to.
