Title: Method of extracting fatty oil
IPC: C11B1/10
Filed: 1929-06-10
Abstract: 336,274. Sato, M., and Ishida, Y. June 10, 1929. Fatty oils, extracting by solvents.-Fatty oils are extracted from soya bean and similar fatcontaining materials by mixing the raw material with ethyl alcohol or similar solvent, to which has been added benzine and benzol, the said alcohol in the mixture being at such concentration and in such quantity that the water in the resulting liquor is less than 10 per cent, dissolving the fatty oil by heating the mixture to above 65‹ C., and then drawing off and cooling the extract to a temperature below 50‹ C., to separate the oil therefrom. The raw materials may be pre-dried prior to extraction. In a suitable apparatus operating in a continuous manner, the raw material contained in an extractor 1 is heated with the solvent and the extract passes through pipes 9, 11 and 12, and through a heater exchanger 3 and a pipe 14 to a cooler 4. The extract cooled below 50‹ C. then passes through a filter 5 into a separator 6, where are formed a lower layer of oil drawn off through a pipe 15, and an upper layer of solvent, which passes through a pipe 16 to the heat exchanger 3 where it is reheated by the liquid extract, and returns to the extractor. Solvent vapours from the extractor 1 are condensed by the condenser 8. In the last cycle the solvent passes from the separator 6 through the heat exchanger 3 and pipe 20 to a still where the final traces of oil contained therein are recovered. The extracted residue contains a high proportion of nitrogen.

Title: Target evaluation apparatus for collision avoidance
IPC: G01S13/937
Filed: 1973-04-13
Abstract: 1432448 Radar IOTRON CORP 13 April 1973 [13 April 1972] 17927/73 Heading H4D An evaluation apparatus for use with a marine surface radar comprises means providing, at successive azimuth positions of the radar beam, signals representing the near edge of a target, signals representing the far edge of the target and a target envelope end signal when the near and far edge signals coincide. Ships 402, 404, 405, buoy 406 and landmass 407, Fig. 2 all reflect pulses from a continuously rotating radar antenna mounted on the ship. Target 405 will not normally be displayed. On each radar scan, the echoes from radar 110 are processed by evaluation apparatus 112, Fig. 4. S-bits and E- bits are generated and stored to represent the near and far edges of the target envelope. An S-bit is generated after three positive returns from the same range from three consecutive azimuth steps. An E-bit is generated at the first subsequent non-return in any azimuth step in which an S-bit has been generated. As the radar beam sweeps the target, the E- and S- bits trace out the target envelope (Fig. 5, not shown) and coincidence of the E- and S-bits following two consecutive non-returns at the envelope range, signals the end of the target. The number of S-bits generated indicates the target width and this is compared in computer 114 to a predetermined range-dependent number representing the angular width of the largest ship likely to be encountered (e.g. 2000 feet). If the target is wider, the target is designated a landmass, if not it is labelled as a possible ship. Information on the target range, width and land/ship identity is passed to computer 114 which determines whether this target has previously been identified. If yes, the target velocity and heading are calculated using the old and new positions. If not previously encountered, the new target is stored for further use. The position of the target is determined as the centre of the envelope and the ship target is displayed there as an open circle, while landmass targets are displayed as a broken line extending along the near edge (Fig. 3, not shown). The ship velocity and heading are indicated by a vector line drawn from the target circle on the display. The Specification shows detailed diagrams of the digital circuits included in the evaluation apparatus 112 and details of computer programs for digital computer 114 for reading in data from evaluation unit 112 and radar 110, target identification and tracking and display control (Figs. 13-15, not shown). Reference has been directed by the Comptroller to Specification 1,337,966.

Title: Improvements in polymerization of organo-siloxanes
IPC: C08K5/14
Filed: 1945-07-17
Abstract: A liquid organosiloxane with not more than 2.25 hydrocarbon radicals per silicon atom is polymerized by heating at 100 DEG  C. or higher with a diacyl peroxide containing at least one aromatic acyl radical. At least some of the hydrocarbon radicals must be alkyl.  Siloxanes mentioned are methyl, ethyl, propyl or butyl, phenyl ethyl, phenyl methyl, hexamethyldisiloxane.  Suitable peroxides are benzoyl; benzoyl acetyl; dinaphthoyl or benzoyl lauroyl.  The acyl radicals may contain halogen or nitro groups. The peroxide may be mixed with an inert filler such as calcium sulphate.  The peroxide may be added in successive small amounts. Polymerization may be stopped by cooling the mixture and removing excess peroxide by treatment with a reducing agent or by passing oxygen through the liquid.  The reaction is preferably carried out in absence of oxygen, e.g. at reduced pressure or in an inert atmosphere.  In the examples, increase of molecular weight is recorded by measurement of viscosity.  (1) Dimethyl silicone prepared by hydrolysis of dimethyldiethoxysilane with sulphuric acid was heated with different amounts of benzoyl peroxide for varying times at 125 DEG  C.  (2) Diethyl silicone prepared by hydrolysis of diethyldichlorosilane was treated with caustic soda, neutralized with carbon dioxide, and then heated with successive additions of benzoyl peroxide.  (3) A copolymer from acid hydrolysis of a mixture of dimethyl diethoxysilane and methyltriethoxysilane was heated with successive additions of benzoyl peroxide.  (4) Tetramethyltetraphenylcyclotetrasiloxane was heated with varying amounts of benzoyl peroxide.  Other examples describe the heating of triethyltriphenylcyclotrisiloxane, octadecamethyloctasiloxane, phenyl methyl siloxane, phenyl ethyl siloxane, dimethyl siloxane, and a copolymer from ethyl silicate and trimethylethoxysilane with various amounts of benzoyl peroxide for various times and give figures for the changes in viscosity.

Patent GB-183540-A (GB)
Abstract: 183,540. Stappler, S. J. April 19, 1921. Inserting wire and like, metal nails.-Skins are nailed or tacked to a cylindrical carrier 25 for the purpose of being stretched. The nails are delivered from a hopper 24 and are inserted by a hammer mechanism 23 which is automatically traversed step by step longitudinally of the cylinder 25. Circumferential nails 35 are inserted by the mechanism 23 which for that purpose is not traversed but the carrier 25 is rotated automatically or by hand. Nails are delivered by known means automatically to fingers 86 which hold the nail till it is driven by a hammer 45. The fingers on withdrawal of the hammer slip over the head of the nail. The hammer 45 is operated by a rod 44 and crank 50 driven by a worm wheel 51 off a motor 53. Each rotation of the crank 50 corresponds with the action of a cam 103 on the crank-shaft to operate a bellcrank 99 which through pawl and ratchet gearing advances or retracts the whole nailing-mechanism mounted on a carriage 22 along a rack 93 parallel with the carrier 25. The rod 99, Fig. 4, operates bell-cranks 95 carrying pawls 96 to engage rackteeth 94 connected with shafts 90, 91. Rotation of the shaft 90 traverses the carriage to the right. Either pawl 96 is allowed to be in action for longitudinal traverse right or left as the case may be by operating a handle 107, Fig. 5, connected to levers 105 engaging the pawls at 104. Both pawls are held out of action so that the carriage 22 is not traversed while the carrier 25 is rotated. The carrier 25 can be rotated by a hand-wheel 36 detachably spring-clutched to worm gearing 29. In this way the carrier can be detached from automatic feed by the worm wheel and be set by hand. The worm wheel is driven by a worm 28 rotated by shafting 30, 33. The shaft 33, Fig. 1, is driven by a ratchet and pawl 113 from a bar 114 oscillated from the main shaft 43. The hopper is driven by friction wheels 54, 56 and gearing 116, 118, 117.
