Abstract: 270,395. Cave, N. F. Feb. 5, 1926. Protectors. - A device for preventing the unauthorised opening of a book comprises a clip or shield 26, Fig. 5, or a pair of connected clips or shields 10, Fig. 3, adapted to engage over the edges of the book cover at the front corners thereof, means being provided for locking the device in position on the book. The front portions 11 of the two shields 10 are connected by a metal strip 15, which is cranked inwardly at 16, and a closed metal band 17 is secured externally around the upper portions 12 of the shields. The shields mav be secured at the front edge of the book by a lock 20, Fig. 1, hinged upon one longitudinal edge 21 of the cover and extending over the strip 15 to the other edge 21 where it is secured. Alternatively, a lock attached to one end of a leather strap or flexible metal band may be secured upon the strip 15, the strap or band being passed around the sides and back of the book and engaged by the lock at its other end. The shield 26, Fig. 5, has a strap 28 secured at one end 29 to the stiffening band 17, and a lock 30 upon the opposite portion of the band 17 to secure the free end of the strap. The stiffening band 17 may be dispensed with, the end of the strap and the lock 30 being then attached to the side flanges 25 of the shield. The shields may be pressed from a single blank of sheet metal, leather, or other material.

Title: Method of and apparatus for performing fractional distillations under a vacuum
IPC: B01D3/00
Filed: 1959-08-12
Abstract: <PICT:0929747/III/1> <PICT:0929747/III/2> <PICT:0929747/III/3> In a high-vacuum still comprising a cylindrical evaporating surface 12 and a condensing surface 14, fractionation of a mixture is acheived by means of rotating spiral member 2, provided with pocket-shaped perforations 13, mounted between the evaporating and condensing surfaces.  The spiral member 2 is rotated on shaft 4 in the direction indicated in Fig. 3.  The evaporating surface is surrounded by heating-jacket 17.  The distilland, introduced through pipe 11, is distributed over the evaporating surface from a plate 3, which is rotated by shaft 4.  The distilland flows in the form of a film down the evaporating surface, and is partially vaporized.  The vapours condense on the outer surface of the first convolution of rotating member 2, and, the condensate passes through the perforations to the inner surface, whence the more readily volatile components distil over to the next convolution, whereas centrifugal forces cause the less volatile components to flow along the inner surface of the member 2 in an outward direction.  The vapours distilled off the inside surface of the innermost convolution are condensed on surface 14, and this distillate is collected in trough 15.  The non-distilled residue, flowing off the bottom of surface 12, collects in collar 25.

As soon as flow takes place past the valve, the fluid pressure in chamber 14 which helps to load the valve towards the closed position will be lessened. The piston 9 is provided with sealing packing 10. The contacting surfaces of the valve and its seat may be rounded, as shown, or coned.

Abstract: 888,372. Xerographic plates. HARRISINTERTYPE CORPORATION. Feb. 17, 1958, No. 27714/61. Divided out of 888,371. Class 37. [Also in Group XVI] A blank from which a lithographic printing plate may be produced consists of a plate carrying a dried substantially water-insoluble hydrophilic coating consisting of polyacrylic acid resin and finely-divided zinc oxide, the weight of zinc oxide in the layer being 2 to 25 times the weight of resin. The coating may be applied from a dispersion of the zinc oxide in an aqueous solution of the resin. Since the resin may form water-insoluble precipitates with zinc oxide at an acid pH, the solution is preferably neutralized, before addition of the oxide, with a volatilizable alkaline material such as aqueous ammonium hydroxide or monoethylamine. In an example, 144 grams of zinc oxide are dispersed in an aqueous solution containing 36 grams of polyacrylic acid neutralized with 50 c.c. of ammonium hydroxide and the dispersion coated on a plate and heattreated at 150‹ C. for 30 minutes to drive off water and convert the applied dispersion to a water-insoluble hydrophilic film. The blank is also described in Specification 888,371, from which the present application is divided.

Abstract: 228,627. Pilkington Bros., Ltd., and Le Mare, E. B. Nov. 7, 1923. Rolling.-Relates to apparatus for producing a continuous strip of glass in which the molten glass flows from a tank on to a moving table or roller and forms a pool which is carried into the pass of the rolling apparatus. According to the invention, the edges of the pool are protected from excessive cooling by side walls which extend the whole length of the pool up to the pass of the rolling apparatus. In the, construction shown in Fig. 2, the glass flows from a tank through a conduit 4 and forms a. pool 9 on a chain table 2 by which the glass is continuously carried from the pool beneath a roller 1. The pool is confined by side walls 11, Fig. 1 which extend from the mouth of the conduit up to the pass between the roller and the table, the walls being heated by gas jets 12 which direct heating gases into conduits 13 in the walls. The upper portions of the walls may be curved upwards and inwards so as to overhang the pool in order to diminish radiation from the edges of the pool. Instead of the gas jets 12, the walls may be heated by electric conductors, or they may be packed with heat insulating material. The walls mav be suitably shaped for use with apparatus in which the pool is formed on a large roller instead of the chain table.

Title: Improvements in the estimation of hop bitter substances in beer
Inventor: AKHTAR MOHD
IPC: B01D11/04
Filed: 1961-08-03
Abstract: A process for estimating hop bitter substances in beer comprises passing it through a water-insoluble solvent for the substances in such manner that beer drops are formed which move at a velocity less than that at which an emulsion is formed but sufficient to cause turbulence inside the drops so that more than 60% of the substances pass from them into the solvent, continuously supplying and removing the latter and estimating the percentage of said substances in the solvent removed.  An apparatus (Fig. 2, not shown) for effecting the process comprises a chamber 21 containing a rapidly rotating plate 23, an inlet pipe 22 for beer directed towards the centre of the plate, the chamber having a separate inlet 29 for the solvent, an upper outlet for the solution 30 and a lower outlet 31 for the spent beer.  Also described (Fig. 1, not shown) is an apparatus in which beer is fed down a vertical pipe 4 and through a jet head containing a number of small jets into a chamber 3 through which solvent flows upwardly.
