IPC: B65D83/14
Filed: 1963-04-25
Abstract: 957,294. Dispensing liquids by gaseous pressure. HAARKOSMETIK UND PARFUMERIEN G.m.b.H. April 25, 1963 [May 2, 1962], No. 16392/63. Heading F1R. [Also in Division B8] An exchangeable metering valve for dispensing a gas-pressurized liquid foam or paste from a dispenser provided with an outlet valve comprises a chamber 2 disposed inside a casing 1 and displaceable against the action of a spring 5, the chamber having a pipe 3 for connection with the dispenser valve, an opening 4 closable by a valve element 6, and a sealing element 7 normally closing the entry end of an outlet pipe 8. In operation, when the metering valve casing 1 is depressed, the entry end of the outlet pipe is first uncovered and, almost simultaneously, the opening 4 is sealed by the element 6. Continued downward pressure on the casing causes the pipe 3 to open the outlet valve in the dispenser and thereby permits pressurized liquid to enter the chamber 2. Upon release of the pressure on the casing, the outlet valve in the dispenser is closed, the valve element 6 lifts away from the opening 4, and the outlet pipe 8 closed. The liquid in the chamber then flows into the interior of the casing so that upon the next actuation of the metering valve the liquid is dispensed via the outlet pipe.

Abstract: An ion-exchange reagent comprising a layer of styrene-divinyl benzene copolymer ion-exchange resin coated upon, and at least partially polymerized upon, the surface of an inert extender of large superficial area is used for the separation of protein and polypeptide molecules from their solutions.  In examples styrene and divinyl benzene are polymerized in the presence of benzoyl peroxide, methyl alcohol or chloroform, and a diatomaceous earth treated with dichlorodimethyl silane, and the coated extender sulphonated to form the ion-exchange resin.  Other conventional functional radicals may be used.  The composite resin is used to separate the proteins in a solution of insulin, or the peptides from a mixture prepared by the hydrolysis of insulin with crystallized trypsin.ALSO:Proteins and polypeptides are separated from solutions containing them e.g. insulin, and a mixture of peptides prepared from the B-chain of insulin by hydrolysis with crystallised trypsin, by adsorbing upon an ion-exchange reagent comprising an ion-exchange resin based on a styrene-divinyl benzene copolymer coated and at least partially polymerised on an inert extender of large superficial area e.g. diatomaceous earth.  The separation is by chromatographic methods and a copolymer of styrene-divinyl benzene containing 5 to 15% of divinyl benzene is preferred for the separation of protein and 0,5 to 2,1% of divinyl benzene for the separation of polypeptides of MW 500 to 5,000.  Examples describe the use of sulphonated copolymer coated upon diatomaceous earth for the treatment of insulin solutions of varying purity, and the mixture of peptides referred to above.ALSO:Insulin is separated from solutions containing same by adsorbing upon an ion-exchange reagent comprising an ion-exchange resin based on a styrene-divinyl benzene copolymer coated, and at least polymerized upon an inert extender of large superficial area e.g. diatomaceous earth.

Abstract: 1,090,655. Air brakes. C. HUBERT. April 21, 1965 [April 21, 1964], No. 16687/65. Heading F2F. A compressed air brake installation for use with railway trains comprises a central control station connected via a train brake pipe to brake devices disposed on the various vehicles, wherein the control station has provision for producing a partial vacuum in the train pipe and each brake device has associated with it a valve connected to the brake pipe and arranged so that, when the train pipe pressure is reduced below atmospheric pressure, connects to the atmosphere the appropriate parts of the brake device to release the brakes. The valve 2, which may also be operated manually to release the brakes, has five conduits 99, 171, 183, 191 and 192 connected respectively to the train brake pipe, atmosphere, the triple valve, the auxiliary reservoir and the brake reservoir. A moderate raising of rod 189 connects chamber 168 to atmosphere by passage 188, venting the brake reservoir. A further raising of member 189 lifts member 187 to vent the auxiliary reservoir. Still further raising of 189 liftt system 170 and applies the disc 181 to its sea- 180, chambers 165 and 166 then communicating. If the brake pipe pressure in 164 is atmos spheric the build-up of pressure in chamber 165, with its restriction 171a, maintains the system 170 in a raised position. When operation of rod 189 ceases the emptying of the auxiliary and brake reservoirs ceases, but the brake cylinder is emptied through the triple valve, and chambers 166, 165. If the pressure in the brake pipe is at operating, i.e. a higher than atmospheric pressure the emptying action ceases when 189 is released. When a partial vacuum is applied to the brake pipe and chamber 164 the system 170 rises and the brake cylinder discharges through passages 176-178 and 171. Disc 181 has closed on seat 180 and the auxiliary and brake reservoirs do not close. In another embodiment of the valve (Fig. 1, not shown) three conduits (99. 108, 116) are provided and are connected to the brake pipe, to atmosphere or to the auxiliary reservoir respectively.

Abstract: 1320886 Folding paper F M BIGGAR JNR 11 April 1972 [29 Dec 1971] 16701/72 Heading B8R [Also in Division B6] An output shaft 10, Fig. 1, of a printing press drives in fixed speed relation an intermediate shaft 20 through gear or other means 14, 16, 22, 18. The shaft 20 drives, in fixed speed relation with the shaft 10, the shaft 30 carrying the feed roll 32 of a fanfolding machine, through gear or other means 24, 26, 28. The shaft 20 also drives, in fixed speed relation with the shaft 10, an input section 50, Fig. 3, of a shaft 42 carrying a wheel 44 on which is mounted the eccentric 46 for driving the oscillating folding member of the fanfolding machine. The section 50 and an output section 54, Fig. 3A, are connected by a coupling 48. The coupling 48 comprises a wormwheel 58 fixed to the section 50, and an assembly fixed to the section 54 and comprising an electric motor 62, a counterweight 60, and a body portion 70 supporting a shaft 68, to which is fixed a worm 72 engaging the worm-wheel 58 and a worm-wheel 66 engaging a worm 64 on the motor output shaft. The motor is reversible and energized through a brush block 76, and a slip ring assembly 74 caused by the section 54, under the control of finger depressible switches. With the motor idle, the sections 50, 54, and thus the shaft 10 and the folding member, are coupled together in fixed relationship. By energizing the motor, the folding member can be caused to operate faster or more slowly than the shaft 10, and this adjustment can be made while both the press and the folding machine are operating. The folding machine is thus adjustable according to the printing press speed and the fold length required.
