Title: An improved process for the manufacture of dipropylketone
IPC: C07C45/54
Filed: 1924-05-08
Abstract: Dipropylketone is prepared by heating a mixture of dry calcium butyrate with an inert substance such as sand or dry clay to a temperature of 300-400 DEG  C. and condensing the product.  The calcium butyrate is derived from the butyric fermentation of sugars, glucosides, polysaccharides, amino-acids, &c., in the presence of calcium carbonate, and contains a small percentage of calcium acetate and propionate.  The decomposition is effected in a retort provided with a mixer and fitted with a condenser, and may be rendered continuous by the use of a conveyer worm for passing the material through the retort.  The crude dipropylketone may be purified and concentrated and can be used as a fuel for internal combustion engines.  The Specification as open to inspection under Sect. 91 (3) (a) states the process is applicable to the production of ketones in general by distillation of the corresponding calcium and other salts. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in lubricating systems
IPC: F16N27/00
Filed: 1933-04-19
Abstract: 403,274. Lubricators. BEAUDOUIN, M. J. L. P., 12, Boulevard Pereire, and BALEINE, G. D. DE, 42, Avenue Rapp, both in Paris. April 19, 1933, No. 11450. Convention date, April 25, 1932. [Class 12 (iii).] In a lubricating system having a number of feed control devices 3 supplied by a common source each of which has an air chamber 1 into which lubricant is forced during a high pressure period so that the air inside is compressed, the pressure of the air forcing lubricant to the outlet 8 of the chamber and to a delivery conduit 11 when the high pressure at the source is reduced or cut-off, a pressure control device 4 in each feed control device closes the conduit 11 when the air pressure has fallen to a predetermined value, so that the amount of lubri - cant delivered depends upon the difference between the maximum pressure of the source of lubricant and the minimum pressure permitted within the air chamber. In Fig. 3, the air chamber is formed in a tube 1 preferably of glass held in a body 3 by a member 2. The body 3 has a bore containing the pressure control device or piston 4 which is pressed on its inlet side by a spring 6 having an adjustable abutment member 7 and is constantly in communication at its outlet end with the outlet 8 by reason of a stop screw 5. Lubricant admitted at 12 passes into the bore, through an inlet 9 past the ball valve 10 and into the air chamber. The inlet pressure acts on both ends of the piston 4 so that the spring 6 maintains it against the stop 5. On releasing the inlet pressure, the air pressure forces back the piston 4, Fig. 7, so that the delivery conduit 11 is uncovered, the passage 9 being closed by the valve 10 and subsequently by the piston 4. Fig. 7 also shows a slight modification in which the stop member 5 is replaced by a member 14 which guides a rod 15 having a head 17 constantly urged towards the member 14 by a spring 16. This arrangement enables an extra supply to be delivered to any single control device by merely pushing the rod 15 inwardly.

Title: Method of recovering magnesium salts from sea water
Inventor: BAKER ALBERT BYRE
IPC: B01J39/04
Filed: 1956-04-16
Abstract: In recovering magnesium salts from an initial aqueous solution containing magnesium, calcium and sodium salts, such as sea water, by contacting the solution with a cation exchange resin and subsequently eluting the absorbed magnesium ions with an aqueous alkali metal salt, the initial solution first has the calcium ions selectively removed.  The calcium may be removed by precipitation with an alkali metal carbonate, e.g. sodium or potassium carbonate or ammonium carbonate equivalent to at least 75 per cent of the calcium salts, together with an alkali such as ammonia, or ammonium, potassium or sodium hydroxide, if desired at 10-80 DEG  C. The final solution should have a pH of 8.5-9.5.  The liquid may if desired be seeded with powdered calcium carbonate.  After removal of the calcium the liquid may be diluted e.g. with an equal quantity of fresh water.  It is then fed to one or more moving or fixed beds of ion exchange material through which, in an example, it is moved upwardly.  The resin used is preferably a sulphonated insoluble cross-linked vinyl aromatic resin in the sodium form, e.g. a sulphonated copolymer of monovinyl and polyvinyl aromatic hydrocarbons or a sulphonated copolymer of styrene, ar-ethyl-vinyl benzene and divinyl benzene, but sulphonated phenol formaldehyde resins are also referred to, and the resin can be in hydrogen form.  After contacting the resin with the pretreated solution, it is eluted with a solution containing at least 10 per cent of an alkali metal salt, e.g. sodium chloride: in an example a saturated solution is used. U.S.A. Specification 2,387,898 is referred to.

Title: An improved method and apparatus for hooping railway sleepers and like wooden articles
IPC: B65B27/10
Filed: 1949-05-02
Abstract: 665,564. Angular bending. DELOR, G. C., and SOC. METALLURGIQUE DE L'ESCAUT. May 2, 1949 [May 26, 1948], No. 11636/49. Class 83 (iv). [Also in Groups XXIII and XXX] In hooping the ends of wooden railway sleepers and similar articles to prevent splitting, a hoop is pressed into the sleeper by applied mechanical pressure which simultaneously compresses the adjacent portions of the wood, and the pressure is maintained while the ends of the hoop are secured together, the subsequent release of the pressure allowing the wood to expand to a certain extent. The machine is preferably provided with milling cutters, disposed in front of the hooping apparatus, for forming a groove in the face of the sleeper near each end to receive the ends of the hoops and the means for joining them. The transversely grooved sleeper is carried to the hooping position by an endless conveyer provided with pivoted dogs or carriages which push the sleeper horizontally and then lower it vertically on to transverse supporting members within a looping hole. A clamping-bar 15 is next lowered upon the face of the sleeper, closely adjacent to the groove, and a metal hooping-band or strap 16 placed in the position shown in Fig. 5 is pressed into the face 18 of the sleeper by a hydraulicallyoperated horizontal pressing-slide 17, the opposite side 25 being in abutment with sidepieces or stops 18a on a fixed abutment 19. A slidable member 22a carrying a roller 20 and series of rollers 22 is next moved horizontally below the sleeper to press the hoop into the lower face 21, this movement serving also to stretch the loop around the corner between the faces 18, 21; the rollers 22 maintain the hoop within the face 21 and press the sleeper against the clamping-bar 15. The mounting 22a for the rollers 20 and 22 is associated with a lever 23 which at the end of the movement of roller 20, is swung round to operate a lever 23a and slide 23b to drive the hoop 16 between the face 25 of the sleeper and a slide which is mounted within the fixed abutment 19 and yields to allow the hoop to be positioned adjacent to the face 25 before the slide is moved horizontally to press the hoop into it, the adjacent part of the sleeper also being compressed. The final bending is effected by rollers 26, 26a, which are moved horizontally towards one another and operate to bring the ends of the hoop together for joining in any manner, after which the sleeper is removed by a conveyer 14. The wirehooping apparatus may be duplicated to enable both extremities of a sleeper to be operated on simultaneously, a relative longitudinal adjustment being provided to enable sleepers of different lengths to be hooped. The Specification as open to inspection under Sect. 91 comprises also a drilling apparatus to drill a series of holes in the underside of the sleeper to facilitate its impregnation with woodpreservative. This subject-matter does not appear in the Specification as accepted.
