Title: Unit for treating and feeding liquids particularly water
IPC: E03B7/07
Filed: 1974-07-30
Abstract: 1470874 Handling liquids VITCO PATENS AG 30 July 1974 [7 Aug 1973] 33620/74 Heading A4T A unit for treating and feeding e.g. water comprises a circuit including a flow control device 11, at least one electrically operated valve 12, 13 for opening and closing the circuit and a collecting tank 34 with discharging means 21 for the treated water. Water enters through a union 8 and manually operable valve 5 and flows through the device 11 and valves 12, 13 to be discharged into a treating element 18, e.g. for dechlorination, lime removal, desulphurization or deodorization. The treated liquid flows through a peripheral space around the element 18 to a tube 22 which conducts it to a collecting tank 34, where it is retained until discharged through a coupling 21. The tank 34 has a switch (25), Fig. 1 (not shown), controlled by a float (24) for closing the valves 12, 13 when the tank level reaches a predetermined upper limit, and a further float (26) is operable to prevent discharge or provide an indication when the level falls below a predetermined figure. To maintain uniform pressure within the tank 34 a first single-acting valve allows air to escape during filling, while a second such valve 31, provided with an air filter 30, allows air to enter during discharge.
Patent GB-632304-A (GB)
Title: Improvements relating to the extraction of vegetable oil
IPC: C11B1/10
Filed: 1946-11-12
Abstract: Oil is extracted from seeds, beans and nuts by a continuous solvent extraction process which is over-all on the counter-current principle and which consists of two or more stages, in each of which the flow of seeds &c. and solvent is concurrent.  Each stage comprises the steps of dispersing oil-containing seeds or seed-solids in an extracting liquid of lower specific gravity than the seed solids to form a slurry, thickening and compacting the seed-solids in a solid bowl centrifuge to produce a substantially solid-free miscella, and to separate the substantially solid-free miscella from the thickened and compacted solids; and the further step of moving the seed-solids and miscellas countercurrent between the stages, whereby the miscella from one intermediate stage or from the final stage is employed as an extracting liquid in a preceding stage.  The seeds &c. may be triturated before dispersion in the initial extraction stage and the solvent may be recovered from the miscella produced in the initial extraction stage to produce a substantially solid-free extracted oil. The recovered solvent may be recirculated to the final stage and used there as an extracting liquid.  The amount of solvent introduced in the final stage and of seeds &c. introduced in the initial stage may be proportioned to produce a miscella in the initial stage containing from 15 to 30 per cent by weight of oil.  The seeds may be flax seed and the solvent may be hexane, the rate of feed of these to the process being proportioned to produce a miscella in the initial stage containing 20 to 30 per cent by weight of linseed oil. Alternatively the seeds may be castor beans and the solvent heptane, the feed rates being proportioned to produce a miscella in the initial stage containing 15 to 25 per cent by weight of castor oil, the temperatures of the slurries being maintained at not substantially less than 50 DEG  C.  The process is said to be particularly applicable to seeds &c. which, unlike soya beans, disintegrate upon contact with an oil solvent after trituration to form slurries containing substantial quantities of gelatinous material which render continuous solvent extraction by the usual methods difficult.  Thus, the process is said to be applicable to linseed, cottonseed, castor bean, perilla, sunflower seed, hemp seed, peanut, oiticica, tungnut and coconut.  The number of stages used in the process may be sufficient to extract at least 98 per cent of the oil and to leave a residue of extracted solids containing less than 1 per cent of oil, and may vary from two to six or more, three usually sufficing.  The final miscella from the initial stage may be clarified by means of a "polishing" filter and the seed to be extracted may have been given a prior treatment such as the removal of a portion of the oil by pressing.  Any of the usual oil solvents may be used individually or mixed provided that the requirement regarding specific gravity is satisfied.

Title: Improvements in plate shearing machines
IPC: B23D17/06
Filed: 1963-08-26
Abstract: 983,038. Shearing. E. BREETWELT. Aug. 26, 1963 [Sept. 6, 1962; July 9, 1963], No. 33721/63. Heading B3W. A sheet shearing machine comprises a pair of flat beams centrally pivoted together, shearing blades in each beam adapted to co-operate in pairs with a scissors-like action and on each side of the pivot, said beams being stiffened by the addition of rib-like members. The machine includes two beams 11 and 12 held together by a pivot 13. The beam 11 is stationary and has secured thereto a work-supporting table 14. A slot 15 passes through both beams, which have blades 19, 20, 21 and 22 mounted in them, the blades 19 and 21 are tapered longitudinally to correspond with the recesses in which they are mounted, and can be moved longitudinally by hydraulic jacks 27 and 28. The beam 12 is rotated relative to the beam 11 by an hydraulic jack 16, the bolts 29 running in curved slots 30 prevent separation of the blades during cutting. There is a clearance 40 in beam 11, above the pivot 13 so that the beam 12 can also move bodily relative to the beam 11. The beams are stiffened by members 31,32, 33 and 34. Operation.-Sheet material to be sheared is passed through the slot 15 and the jacks 27 and 28 are operated to move the blades 19 and 21 and thus lower them on to the work, to act as a hold-down. The jack 16 is then operated to rotate the beam 12 so that the work is sheared from both edges towards the centre. When the beam 11 strikes a stop 37, it is able to lift bodily, due to the clearance 40, to shear the centresection of the work. The outer ends of the blades may be concave so that the initial power required is reduced.

Title: Indirectly pumped high energy laser
IPC: H01S3/23
Filed: 1964-08-20
Abstract: 1,081,011. Lasers. GENERAL ELECTRIC CO. Aug. 20, 1964 [Sept. 4, 1963; Sept. 25, 1963], No. 34137/64. Heading H1C. In a laser a disc of laser active material and a light pumping source are positioned in a housing having a reflective inner surface so that the end surfaces of the disc are pumped. In the arrangement shown in Fig. 1 a disc 1 of neodymium doped lanthanum borate glass is supported in a metal housing 2 with its longitudinal axis perpendicular to the longitudinal axis of the housing 2 and aligned with apertures 4, 5. A plurality of lamps 8 are disposed adjacent each other to form a plane passing through the centre of the disc 1 and adjacent lamps are separated by reflector members 10 which direct the lamps' radiation toward particular areas of the reflective inner surface of housing 2 and thence to one or both of the end faces of disc 1. If the lamps are flash operated the reflectors 10 also function as trigger electrodes. The terminals and wires are brought out through removable panels 7 in end walls 6. If the housing is elliptical the lamp-reflector plane and the laser disc are positioned at the conjugate focii of the ellipse. A selective radiation filter may be provided between the lamps and disc to reduce heating of the disc or forced air or liquid coolants may be provided. The end faces of disc 1 are coated with a low reflection coating and need not be optically flat, and the housing is contained in an optical cavity formed by a plane mirror and a prism, Fig. 3 (not shown). In the embodiment of Fig. 2 the housing 2 is a sphere and the lamps 8 are curved. A glass filter 33 divides the housing into two parts. The disc-shaped laser members may be of generally square or rectangular cross-section, Fig. 3 (not shown). In Fig. 4 (not shown) a plurality of housings (2) and associated apparatus are arranged in an optical cavity and optically coupled to adjacent housings so as to provide an oscillator. The oscillator of Fig. 5 offers a higher degree of mode selection than that of Fig. 4 and comprises a plurality of housings 2 arranged between two crossed Porro prisms 15 and 16. The energy is extracted from the cavity by means of partially reflective mirror 17 and prism 18, and mode selection is achieved by rotating prisms 15, 16 about the axis defined by the roof edge 19 so that the on-axis mode falls within the critical angle of the total internal reflective surfaces formed by the prism and the off-axis modes are not reflected. In an amplifier, Fig. 6 (not shown), a Q-switched laser oscillator (30) has its output amplified by a chain of lasers in housings (2), no optical cavity being provided in this case for the single pass lasers. The lasers shown in Figs. 1, 2, 3 may be pulse operated or continuously operated. The reflective inner surfaces of the housing may comprise a plurality of small flat mirrors to provide controllable focusing of the lamps' radiation upon the end faces of the disc. Ruby can be used as the active material and the cross-section of the disc need not be circular, other configurations being disclosed.
