IPC: C12H1/14
Filed: 1974-04-17
Abstract: 1468405 Treating milk ALFA-LAVAL AB 17 April 1974 [19 July 1973] 16893/74 Heading A2D  A method of treating a -liquid, e.g. milk, with hydrogen peroxide to increase the keeping quality of the liquid comprises generating the hydrogen peroxide in the liquid by enzymatic means. In the case of milk, the hydrogen peroxide may activate the lactoperoxidase-thiocyanate system therein to form antibacterial substances in situ. The liquid can be mixed with an enzyme and a substance that can release hydrogen peroxide under the influence of said enzyme. Alternatively the liquid may be mixed with an enzyme or enzyme system that can generate hydrogen peroxide in conjunction with a substance present in the liquid. Further the liquid may be mixed with a substance that can generate hydrogen peroxide under the influence of an enzyme that is normally present in -the liquid. The enzyme or enzymes may be attached to a matrix. which is positioned in a vessel, and the liquid brought into contact with said enzyme or enzymes by suitable flow means (Fig. 3, not shown). Suitable enzymes are glucose oxidase, L-amino acid oxidase, galactose oxidase, xanthine oxidase, and a mixture of #-galactosidase and glucose oxidase. The liquid under treatment may be cooled.

The compounds are prepared by the alkylation of the corresponding compounds in which R 2  is H, or mesyl and if desired, hydrolysing the resulting esters. PGE 2  15-alkyl ethers may also be obtained by hydrolysing the corresponding 11-(tetrehydropyra-2- yloxy)-PGE 2  15-alkyl ether, obtained by oxidizing the appropriate 11 - (tretchydropyran - 2 yloxy)- PGF 2 α 15-alkyl ether, resulting from the W 1 H 19  alkylation with compounds of the Hal-(CH 2 ) 4 - COOH of 3α - (tetrahydropyran - 2 - yloxy)- 5α - hydroxy - 2# - (3 - alkyloxy - trans - 1- octenyl) - 1α - cyclopentaneacetic acid γ-lactones. PGF 2 α 15-alkyl ethers are also prepared by hydrolysing the corresponding 11-tetrahydropyran - 2<SP>1</SP>- yloxy - PGF 2 α 15 - alkyl ethers. PGF# compounds are also made by reducing the corresponding PGE compounds, in which the 11-hydroxy group may be protected by a trimethylsilyl group, followed by, if necessary hydrolysis of the trimethylsilyl group, and separation of the PGF# from the product. PGA derivatives may be obtained by the acidic dehydration of the corresponding PGE compounds. PGB compounds are also obtained by treating the corresponding PGE or PGA derivatives with bases. Compounds in which E is -CH 2 CH 2 -, W is 1-pentyl and V is (CH 2 ) 5  are prepared by hydrogenating the corresponding compounds in which E is trans -CH=CH- and V and W are as first defined. 15-Mesyloxy-PGA, methyl ester is obtained by reacting PGA 1  methyl ester with methanesulphonyl chloride. Pharmaceutical compositions, suitable for oral, parenteral, rectal or topical administration contain the above novel compounds together with pharmaceutically acceptable carriers. The compounds possess activities similar to natural prostaglandins.

A cap 12, e.g. for the screw-threaded neck of a plastics bottle, encloses a sealing member 14 comprising two permeable packing discs 32, 34, the disc 32, which is placed in contact with the inner surface of the cap crown, having peripheral slots 36, and the disc 34, which is placed in contact with the first disc, being provided with an impermeable layer 38 on its surface remote from the disc 34 having small perforations 40 therein. The perforations 40 extend into, but not fully through, the disc 34. When placed on the bottle neck (24), Fig. 2 (not shown), the layer (38) engages sealingly with the top edge (28) of the neck, the perforations being too small to permit escape of liquid. If an internal pressure develops within the bottle the lower disc 34, Fig. 1, flexes into the spaces provided by the slots 36 in the top disc 32, thereby allowing the pressure to be released past the screw-threads. If a vacuum develops within the bottle, air flows in through the permeable disc 34 and perforations 40. In the preferred form the two slots 36 both lie within the same half of the disc 34, which is of paperboard &c. The layer 38 may be of a vinyl plastics material, and the cap itself of a rigid plastics material.

Abstract: 1,134,630. Printing spherical objects. A. SCHECK. 20 April, 1966 [19 Aug., 1965], No. 17310/66. Heading B6C. In an automatically operated multi-station screen printing machine for printing the complete surface of a spherical object and in which the object rotates during printing whilst held in diametrically opposed gripper jaws, means are provided for releasing the object from the jaws between stations so that areas previously covered by the contacting jaws may be subsequently printed. In the machine shown, Fig. 2, a ball 6 is held by a pair of gripper jaws 4 and moved to a printing station 20 where the ball is printed in its equatorial region by a reciprocating slidable screen 24. From this station the ball, still held by the jaws 4, is moved to station 21 where, with the aid of a swivelling screen 26 and a displacement through approximately 45 degrees of the jaws 4, a region of the ball adjoining the already printed region is printed. At the third station 22 a swivelling screen 10 and a movement through 90 degrees of the jaws 4 are used to print that region of the ball adjoining the equatorial region on the other side to that region printed at station 21. From the station 22 the ball is moved in the jaws 4 to a fourth station 23 where gripper device 30 is used to remove the ball from the jaws 4. This device 30 is used to support the ball whilst those surfaces previously covered by the jaws 4 are printed by a reciprocating screen 32.

Set-off, preventing.-A powder spray for preventing set-off on freshly printed sheets is operated by a reciprocating part of the main printing-machine in such a manner that surplus powder on a printed sheet is removed by suction before the next sheet arrives. The apparatus comprises a blower 6 connected by a duct 9 to a powder container 14. A valve 28 is provided between the duct 9 and ducts 11 and 12 leading to the container 14. The valve serves to connect the duct 9 either to an outlet 8 or to the ducts 11 and 12 and is operated from the main machine by rotation by a string and pulley mechanism. Initially the valve 28 connects the duct 11 so that pressure air is directed over an opening 24 in the container 14, along tele. scopic duct 17, 18 to adjustable nozzles 20 over the sheet to be sprayed. Further movement of the reciprocating part of the main machine connects the valve also to the duct 12 which communicates directly with the container 14 so as to stir up the powder. The amount of air admitted through the ducts 11, 12 is controlled by regulator screws 23, 29. The cross-section of the opening 24 may be controlled by plate 26 turned by a handle 25. Further movement of the reciprocating part of the main machine rotates the valve in the opposite direction so that the ducts 12 and 11 are closed and the outlet 8 opened. The blower 6 then serves to suck the surplus powder from a hood 3 arranged over the delivery tray 2 through a duct 4 and filter 5, the air being expelled through the outlet 8. A bulb 32 may be provided in the container 14 so that the amount of powder therein is clearly visible.
