Title: Process and apparatus for the treatment of whale meat and other parts of whales to recover useful products therefrom
IPC: A23J1/04
Filed: 1953-10-01
Abstract: <PICT:0756566/III/1> In a process for obtaining oil from whale flesh, comparatively large pieces of the material are heated under pressure in a cooker in which the outer layers of the material are gradually converted into a sludge; this is passed into a closed decanting chamber maintained under pressure and therein allowed to separate into layers of oil, aqueous liquid and sludge residue; the oil and the aqueous liquid and sludge are withdrawn separately and the pressure on the withdrawn aqueous liquid is released, thereby cooling it; the cooled liquid is allowed to settle, the coarse grax constituents are removed therefrom, and then the liquid is heated under pressure to a temperature above that to which the initial material was heated and evaporated under pressure, the steam thus liberated being used to heat the material in the cooker.  As shown, the whale flesh is cooked in cookers 1A and 1B of the type comprising an outer pressure cylinder and an inner rotating perforated drum, operating at 4 atmospheres and 152 DEG C. A continuous stream of sludge liquid is drawn from the spaces between the rotary drums and cylinders and passed to decanters 4A and 4B respectively, from the top of which oil is removed and from the lower part of which a sludge liquid is led through a cyclone, in which pressure is released, to a strainer 5.  From the strainer the liquid is taken through a settling tank 6 and pumps 7 to centrifuges 8 its temperature not falling below 90 DEG C.  The liquid is then conducted to the first of three pressure evaporators 2A, 2B, 2C through a conduit 9 in which a pump is inserted to raise the pressure of the liquid to that prevailing in the evaporator 2A.  The pressure evaporators 2A, 2B, 2C operate at 176 DEG C., 168 DEG C. and 152 DEG C. and pressures of 9, 5 and 4 atmospheres respectively.  Steam is produced in a boiler 3 at a pressure of 10 atmospheres and 180 DEG C.  During the passage from the strainer 5 to the evaporator 2A no substantial precipitation of solids takes place from the aqueous liquid, and during the evaporation in evaporator 2A such fine particles of solids as are present in the liquid will be dissolved.  A concentrated glue water containing about 50 per cent of solids is taken from evaporator 2C and may be dried to produce cattle food or cooked and marketed in semi-fluid condition.

Abstract: 430,784. Intermittent toothed gearing. SCHOLIN, A. R., 319, West Ohio Street, Chicago, U.S.A. Sept. 19, 1934, No. 26981. [Class 80 (i)] Rotary motion of the shaft 10 is converted into intermittent motion of the shaft 12 by toothed gears 14, 15 which mesh with each other, and with gears 13, 11 on shafts 10, 12 respectively, the gear 15 being moved to and fro, along the periphery of the gear 11 by a somewhat circular cam 22. The gear 15 is mounted on an arm 16 freely pivoted on the driven shaft 12 and carrying a roller 21 to engage the cam. The gears 13, 14, 15 are maintained in mesh by arms 19, 20 engaging the bearing pins of the gears 14, 15, and of the shaft 10. The cam has a crescent-like protuberance on its decelerating side to prevent backlash and reverse movement of the driven shaft. A tension spring 24 acting on the bearing pin 17 of the gear 15 keeps the roller 21 in engagement with the cam 22. Specifications 13577 /02, [Class 80], and 356,215 are referred to.

Abstract: 671,442. Staple extractors. SPEED PRODUCTS CO., Inc. Oct. 24, 1949, No. 27286/49. Class 61 (iii). A tool for extracting clinched staples comprises a hooked jaw member J slidably held between a housing H and anvil A, rearward movement of the jaw relative to the anvil being resisted by spring means. In use, the tapered, forked end of the anvil is brought into contact with the bridge of the staple and the, jaw which overlies the staple is retracted, the hooked end drawing the staple onto the fork. The tool, Figs. 2 and 6, for table use has a base A provided with spaced prongs 14. The housing H attached to the base by screws 31 and 33 has a rear part R forming a thumb rest. The jaw member J, provided with a claw 15, has spaced side members 17 slidable on the outside of side faces 18 of the housing, and projecting wings W for finger operation. A U-shaped spring 24 accommodated in a longitudinal recess in the housing is trained around a stud 25, the ends 26 being hooked to lugs 28 on the jaw member. An internally threaded ferrule 20 fixed to the housing receives the screw 33 and slides in a slot 22 in the jaw member, the rear end of the slot limiting the forward movement of the jaw. The wings W coact with the lateral lugs 19 on the thumb rest to limit the rearward movement of the jaw. In a modification, Fig. 11, the manually held tool has a sliding jaw provided with a thumb rest 60 and a stud 61 which is guided in the gap 62 in the fork F<SP>1</SP> for ejecting the staple from the fork on return movement of the jaw.

Filed: 1976-07-01
Abstract: 1508095 Image intensifiers INTERNATIONAL STANDARD ELECTRIC CORP 1 July 1976 [9 July 1975] 27439/76 Heading H1D A method of processing a vacuum tube assembly comprises enclosing an open-ended tube body member containing a microchannel plate electron multiplier in a vacuum chamber for heating and evacuating the tube body, positioning faceplates, one of which is phosphor coated, proximate respective ends of the body member, evacuating the chamber and heating the components, sealing the faceplates to the body member and removing assembly from chamber. The method reduces processing time by rapid removal of gases from plate 9. Fig. 1 includes cathode fibre optic faceplate 1 sealed to metal ring 3 coated with Inconel (R.T.M.) metal and Cu layers both of which may be evaporated followed by a Bi-In alloy (e.g. 1 : 2 layer, porous glass microchannel plate 9 produced by leaching a drawn fibre bundle each fibre having leachable cores and rendered emissive by hydrogen treatment or chemical reduction, tube body 19 with alternating metal and ceramic rings 25 and 13, the former for electrical access to, and support for the tube components and 180 degree twisted fibre optic faceplate 17, with phosphor applied from a water base suspension containing sodium bicarbonate and potassium silicate and an evaporated Al layer. Second metal ring 3 is coated as above. The steps of Fig. 3 (not shown) are not necessarily in sequence, e.g. p/c 7 may be applied in air prior to insertion of faceplate 1 in the vacuum chamber. Components in chamber 21, Fig. 2 are removed by magnetically actuated arms (not shown). Outgassing utilizes heating elements 23. Processing steps are detailed. Channel plate outgassing may be facilitated by electron bombardment. Faceplate seals may be achieved with Sn, In, Bi in various combinations or as a liquid amalgam with Hg. In one embodiment, a metal rod (not shown) skims the In-Bi surface to remove impurities and present an oxide free surface for mating with Au coating 11 of body 19. When the In-Bi surface is clear and highly reflecting, the In-Bi coating 5 is contacted with Au coating 11, either body 19 or plate 17 being rotated. While the tube is within chamber 21, an evaporable type getter may be activated and electronic tests performed. The face-plates may be removed in the chamber by preheating, and spare parts located in the chamber for replacement or reprocessing. Several tubes may be processed at one time. A pressure test may be backfilling chamber 21 with inert gas to > 1 atmosphere and electronically monitoring. The faceplate (17) of Fig. 7 (not shown) is sealed to metal ring 3 by heating to melt an intermediate glass frit. Phosphor coating (15) in Fig. 8 (not shown) is in optical proximity to plate 9. Reference is made to TV picture tubes and glass discharge devices.
