Patent GB-694231-A (GB)
Title: A method and installation for homogenization of liquids
IPC: A01J11/16
Filed: 1948-07-29
Abstract: <PICT:0694231/III/1> Milk and other emulsions are homogenized by feeding the emulsion to the separating space of a centrifugal separator and dividing the emulsion into a sufficiently homogenized component which is discharged from the separator and an insufficiently homogenized component which is fed directly to a homogenizer at or in the vicinity of the centrifugal bowl wall, i.e. that portion surrounding the plates of the separator and rotating therewith. After passage through the homogenizer the now homogenized component may join the incoming feed to the separator.  As shown in the Figure, milk enters at 21 and passes through throat 34 and pipe 22 to the inside of the separator bowl 36.  Milk flows outwardly and upwardly, passing out by channel 39 and pipe 41, whilst cream flows inwardly through channels 26 and 27 to a homogenizer 28.  The cream thrown outwardly is caught in a stationary chamber 32 which may be provided with baffles and passes down pipe 33 to the throat 34.  The homogenizing element may include a cyclone where the cream is brought into rotation before discharge through the homogenizer orifice.  A multiplicity of spaced homogenizers may be provided and they may be directed obliquely backwards reckoned in the direction of rotation of the centrifuge.  Formation of foam may be avoided by operating under vacuum.  The Specification as open to inspection under Sect. 91 comprises also a system where milk is passed first through a pre-heater from which at a temperature of 50 DEG C it is passed through a homogenizer of any type, then through a centrifugal separator, the homogenized milk being withdrawn and the cream recycled to the homogenizer.  Instead of passing the whole of the milk through the homogenizer before separation, the stages may be reversed, the milk passing direct to the separator and the separated cream being homogenized and recycled.  This subject-matter does not appear in the Specification as accepted.

[Classes 120(i) and 120(ii)] A gill spinning frame of the type in which fibres from the faller bed pass around a drawing roller and thence with a change of direction through a smoothing die to a flyer has a guide surface for deflecting the fibres as they pass towards the mouth of the smoothing die. The guide surface may be stationary, moving, or a combination of these. It may take the form of a wall 18 of a conductor 19 mounted on top of a two-part smoothing die 20, 21, Fig. 1, or may be the rear face of a conductor which extends over the drawing roller 11 and embraces the pressing roller 12. This rear face may be fixed or adjustable by a screw 45, Fig. 4. In an alternative embodiment, the guide surface may be pivoted and its upper end may rest against the drawing roller. In a further embodiment, a belt may pass over the pressing roller 12 and downwards over the surface of the drawing roller. Another arrangement, Fig. 10, has an additional roller 51, which co-operates with a plate 53 to deflect fibres downward. Alternatively, the pressing roller 12 may be located in front of the drawing roller 11 and an auxiliary roller positively driven at the same speed as the drawing roller may be mounted on top of the latter. The smoothing die shown in Fig. 1 may be in two parts 20, 21, part 21 being adjustable by a spring and screw 22. Capstans 35 mounted on the flyer may be driven by gear wheels 36 from a pinion 37 on a hollow spindle driven or controlled by a belt 39. The pressing roller 12 may be weighted by a loaded lever 16 pivoted at 17 on a forked guide arm 14.

Abstract: 429,659. Change-speed chain gearing. BOOTH, F., 117, Church Road, Penn Fields, Wolverhampton. July 13, 1934, No. 20553. [Class 80 (ii)] [See also Group XXXI] A change-speed gear, for cycles or motorcycles, of the type comprising a main driving chain A passing around a sprocket wheel on an auxiliary axis, as well as around the usual front and rear sprockets, and a second chain passing around another sprocket on the auxiliary axis and another sprocket on the rear hub, is characterized by the wheel on the rear hub, which is engaged by the main chain, being for low gear drive and being a free wheel, whilst operable clutch means are provided for coupling together and uncoupling the wheels on the auxiliary axis ; high gear drive being effected through the medium of a freewheel on either axis. In Fig. 2, the driving chain passes around sprockets B, C and the second chain over sprockets D, E. The hub H of the sprockets C, E is set forwardly of the hub F to increase the angle of engagement of the chain A around the B, and a jockey J increases the angle of engagement around the sprocket C. The wheel C is rotatable on the hub H on interposed rollers h, and the wheel E is a freewheel, the centre of which runs freely on the hub H. Pins Q project through holes in the wheel C and means are provided to slide the pins into, and out of, holes e<1> in the centre of the wheel E whereby the wheels C, E are connected or disconnected. The means comprise a cable S connected to a bell-crank R which bears against a pin P, slidable through the hub H, and carrying a plate p to which the pins Q are secured. A spring p<4> bearing against a washer p<3> spaced from a shoulder p<1> on the pin P by balls p<2>, tends to engage the pins Q in the holes e<1>. When the pins Q are in the holes e<1>, the high gear drive is effected to the hub F through the wheel D, the hub F over-running the freewheel B. When the pins Q are withdrawn, the wheel B effects a direct low gear drive. In a modification, the wheel E is not a free wheel, so that it is locked, for high gear, to the wheel C. The wheel D is a freewheel so that it can be over-run by the hub F. Additional wheels may be provided on both hubs F, H to give additional gear ratios.

Title: Improvements in and relating to liquid nitrocellulose compostions and to films, coatings and the like obtained therefrom
Inventor: MARRIAN STANLEY FREDERIC
IPC: C09D101/18
Filed: 1951-08-31
Abstract: A liquid cellulose nitrate composition comprises, in solution in a volatile organic solvent, cellulose nitrate and a liquid form of the ester, triallyl pentaerythritol ether ethyl carbonate.  On evaporation of the solvent, clear tackfree films, coatings or the like may be obtained.  These products may be subjected to conditions which promote polymerization of the ethereal carbonate. Triallyl pentaerythritol ether ethyl carbonate is obtained by heating pentaerythritol triallyl ether with an excess over the theoretical quantity of diethyl carbonate in presence of an alcoholysis catalyst, such as sodium ethoxide, and distilling off the alcohol formed in the reaction (see Group IV (b)).  The volatile organic solvent used in forming the cellulose nitrate composition may be acetone, ethyl acetate or methyl ethyl ketone. The cellulose nitrate may be present in a proportion of 1 to 10 times the weight of the ethereal carbonate, which may be used in the monomeric or partially polymerized but still liquid form. Transformation of the triallyl pentaerythritol ether ethyl carbonate to the resinous solid polymerized form may be brought about by heating without a catalyst or with the addition of benzoyl peroxide, succinyl peroxide or similar catalyst, or by addition of a drier such as cobalt linoleate or naphthenate and subsequent exposure to the air.  The liquid cellulose nitrate composition may also contain other ingredients such as blown castor oil, methyl isobutyl ketone, and methyl cyclohexanone.  In an example, a lacquer is made by mixing cellulose nitrate, damped with methylated spirit, liquid triallyl pentaerythritol ether ethyl carbonate, methyl ethyl ketone, methyl cyclohexanone, lead naphthenate, cobalt octoate, and blown castor oil.  The Provisional Specification refers to Specification 649,694.ALSO:Triallyl pentaerythritol ether ethyl carbonate is obtained by heating triallyl pentaerythritol ether with an excess over the theoretical quantity of diethyl carbonate in presence of an alcoholysis catalyst such as sodium ethoxide and distilling off the alcohol formed in the reaction.  An example describes the production of pentaerythritol triallyl ether by interaction of allyl bromide and pentaerythritol and conversion of the ether into the desired carbonate as above.  It may be incorporated in cellulose nitrate solutions suitable for the production of films, coatings and the like (see Group IV (a)).
