Title: Improvements in devices for the study of the fermentative characteristics of living cells
IPC: C12M1/34
Filed: 1963-12-03
Abstract: <PICT:1006774/C6-C7/1> <PICT:1006774/C6-C7/2> A device for detecting the fermentative action of living cells on chemical substances consists of two portions or discs 111, 112, Figs. 4 and 5, of absorbent material in contact with each other, the first disc 111 containing in the dried state a chemical substance which, under the fermentative action of a given species of living cells, will yield detectable degradation products while the second disc 112 forms a hydratable support for the diffusion of the degradation products, and an air- and water-tight layer 113 disposed on the discs so as to cover in part the upper side of the second disc 112 and wholly or partly the upper side of the first disc 111.  The first disc preferably also contains in the dried state an indicating reagent e.g. a colour indicator adapted to detect the degradation products arising from the chemical substance and species of living cells. The discs may be assembled in juxtaposition along a common secant; with this arrangement they may be cut as a single piece from the same sheet of absorbent material.  The second disc may be formed of highly absorbent material capable of retaining a sufficient quantity of liquid for dissolving the chemical substance contained in the first disc and for permitting diffusion of the living cells into the second disc without the need for a separate hydrating supporting medium such as agar-agar. The discs of one or more devices are covered and held by a strip or film 113 of cellulose acetate or polyvinyl chloride. In use the device may be disposed in a Petri box on a layer of agar-agar on which a suspension of the living cells has previously been disposed or provided the second disc is highly absorbent, droplets of a suspension of the living cells may be deposited directly on the uncovered surface of the second disc.

Title: Improvements in the pneumatic separation of minerals
IPC: B03B4/02
Filed: 1951-06-12
Abstract: 706,257. Pneumatic separating. KNAPP & BATES, Ltd., and SWEET, C. T. April 4, 1952 [June 12, 1951], No. 13863/51. Class 117 The dry separation of lump or granular mineral solids is effected by a vibrated or reciprocated sloping air permeable support deck up through which air or gas is passed from a fan 1, the deck carrying a separately mounted transverse riffle 10 to collect the separated solids and allow the remainder to pass over it to a discharge shoot 19, and having means to further increase its slope whereby unseparated material is discharged over the riffle, which initially remains in contact with the support deck, to the shoot, but on still further tilting of the deck the riffle and deck separate so that the separated solids are discharged beneath the riffle to a second shoot 19<SP>1</SP>. To this end the riffle 10 (a rubber strip) may be separately mounted on a spring controlled rod 13 and urged by a spring 18 into contact with the deck but with its downward stroke limited by a stop on the rod. The deck is mounted in a casing 6 which as a whole is vibrated by an eccentric 5 driven from the motor driving the fan, being connected to the feed hopper 7 and fan 1 by flexible connections 9. The deck may be of woven wire cloth to allow fines to pass through for subsequent collection from the windbox 2. A dust hood 17 surrounds the rod 13 beneath the supporting member 14 on the casing.
Patent GB-709567-A (GB)
Title: An improved method of and means for extracting wool grease from wool washes
IPC: C11B11/00
Filed: 1951-06-12
Abstract: <PICT:0709567/III/1> Wool grease is extracted from wool wash liquor by causing air to bubble through the wash liquor in a vat at a temperature less than 40 DEG C., the melting point of the wool grease, to produce a grease-containing froth, the separated froth being then caused to coalesce to a liquid mass rich in wool grease by stirring and heating the froth to a temperature of about 80-90 DEG C. A suitable apparatus for the process comprises a vat 1, a wash liquor feed pipe 2, branch pipes 12 provided with jets 13 supplied with compressed air from a pipe 9, a duckboard constituted by laths 14 located above the surface of the liquid in the vat to separate the froth formed, one or more overflow surfaces 15 provided at the periphery of the vat at a level slightly above the duckboard, and a hood 17 capping the duckboard.  The overflow surfaces 15 feed the froth to one or more containers 16, the froth being urged thereto by compressed air from a pipe 18 having horizontally directed ports. The collected froth in the containers 16 is then coalesced by means of a stirrer 20 and by steam from a ported tube 21 which heats the froth to a temperature between 80 to 90 DEG  C. The liquid mass of wool grease is then removed through pipe 22 by a pump 23.  A valved overflow pipe 3 may be provided and the vat may be of any shape, such as circular.  A number of vats such as described may be used in series for treating a wash liquor poor in wool grease.

Patent GB-337431-A (GB)
Title: An improved process and apparatus for producing glass vacuum-insulated vessels
IPC: C03B23/13
Filed: 1929-05-03
Abstract: 337,431. Aladdin Industries, Ltd., (Assignees of Davis, C. W., and Becker, F. F.). Oct. 29, 1928, [Convention date]. Forming hollow - walled vessels.-A method of producing a vacuum flask consists in assembling two blanks, each having a closed bottom, one within the other, heating the free end of the outer blank until it is plastic, rotating the blanks, and applying pressure to the softened glass to form a neck, and then applying pressure to the adjacent edges of the two blanks to bring them into contact so that they weld and form a rim at the mouth of the flask. The flask consists of an outer blank 1, Fig. 4, and an inner blank 2 united at their necks and separated, as usual, by spacers 8 of asbestos or other suitable material. A narrow ridge or seating 7 is formed at the top of the outer blank to receive the inturned edge of the protective casing. The neck is also flared outwards slightly so that it is supported by the casing. A machine for making the flask comprises vertical shaft 41, Fig. 5, which carries at its lower end a hollow chuck 33 and is rotated at a high speed by a driving-shaft 34. Another vertical shaft, 42, is arranged in line with the shaft 41 and is movable vertically. This shaft carries at its upper end a rotary cap 43 and a spacer 42<a>, Fig. 3, for supporting the inner blank, as shown, while the outer blank of an assembled pair is held in the chuck 33. The machine also includes four shaping-rollers 9 - - 12. The rollers 9, 11 are trebly rotatable on pins which are carried by an arm 27a secured, to the upper end of a vertical shaft 27. This shaft is oscillated by a cam 22a in order to bring the rollers 9 and 11 in turn into contact with the flask. It is moved vertically by a cam 22<b> during the shaping of the neck of the flask. The rollers 10, 12 are carried at the upper ends of vertical rods 28, 31, respectively, which are moved vertically by cams 30<a>, 30<b>. Other cams 23a, 23<b> are used to swing the roller 10 and a gas burner X in an horizontal direction. In making a flask, an inner blank is placed in an outer blank with the spacers 8 in position, and the assembly is supported by the rod 42 and the chuck 33 and rotated. The speed of rotation is such that the glass, when plastic, is forced by centrifugal force into contact with the shaping- rollers. The shaft on which the cams 22, 23, 30 are mounted is clutched to the driving-shaft, and the burner X is swung inwards so that its flames play on the lower parts of the blanks. When the lower part of the outer blank is softened, the conical roller 9 moves into contact with the glass and forces it inwards gradually until the edges of the two blanks are close to one another, and these edges are forced into contact with one another by the roller 10, or a hand tool, until they are welded. The roller 9 is then replaced by a roller 11 which shapes the outer blank to form a neck, as shown in Fig. 3. The roller 12 is also moved vertically against the welded rim and forms the ridge 7.
Patent GB-438199-A (GB)
Title: Improvements relating to the manufacture of artificial fibres
IPC: D01F4/00
Filed: 1934-05-09
Abstract: Artificial fibres are made by spinning in a precipitating bath an aqueous cellulose solution, e.g. viscose containing a protein and a substance adapted to react with the protein so as to fix it in the fibres, or containing a product of the action of such a substance on a protein.  Substances which form condensation or substitution products with the protein such as formaldehyde or tanning agents are particularly suitable.  Also cholic acid or amides such as formamide, acetamide, may be used.  A suitable substance for direct addition to the spinning solution is benzoyl casein.  The condensation product must be dissolved in the spinning solution.  Reaction products of proteins are stable towards alkali and during spinning in a hot acid bath form insoluble products which cannot be dissolved out of the threads, which can accordingly be dyed with wool-dyestuffs.  The protein products may be added before the alkali cellulose is xanthated. In an example, 400 grams of casein are suspended in 1 litre of water and 200 ccs. of formamide or 200 gms. of acetamide together with enough ammonia for dissolution are added.  The whole is heated on a steam bath and then boiled for 2--3 hours.  After cooling and filtering, the solution is added to 10 kilos of viscose (7 per cent alkali and 8,5 per cent cellulose).  The solution is spun in a normal Müller bath.  In another example, 100 grams of albumin are dissolved in 600 ccs. of water and 25 ccs. of 30 per cent formaldehyde mixed with 100 ccs. of pyridine are added.  A small quantity of ammonia is also added and the whole heated to 50 DEG  C. The cooled solution is stirred into 10 kilos of viscose (6,5 per cent alkali and 7,5 per cent cellulose) and the viscose is spun in a Müller bath.  In a third example, casein and tannic are added to viscose; in a fourth, casein and cholic acid; and in a fifth, benzoyl casein is employed.

Patent GB-662572-A (GB)
Title: Process for the manufacture of new acylating agents
IPC: C07C309/17
Filed: 1949-05-26
Abstract: Acylating agents are made by reacting an acid of the formula <FORM:0662572/IV (b)/1> or alkali salt thereof (X = chlorine or bromine) with an aromatic sulphonyl halide or phosgene in the presence of excess of a tertiary base.  Pyridine may be used as base, and a stronger tertiary base, e.g. trimethylamine or triethylamine, may be added during the course of the reaction.  Alternatively, one of the latter bases may be used throughout, in the presence of an inert organic solvent.  N-Methyl-morpholine is also suitable as a base. Preferably the acid and base are mixed and the halide added gradually at 30-40 DEG  C.  The products are believed to be the monohalides of the acids, the sulphonic group not taking part in the reaction.  They may be used for acylating compounds containing -NH- and/or -OH groups, including the introduction of a second acyl group into an amide -NH-CO-R.  Examples are given of the reaction of chloracetic acid sulphonic acid with phosgene, benzene sulphonyl chloride and p-toluene sulphonyl chloride.  The use of the products is claimed in Specification 662,573.  The Specification as open to inspection under Sect. 91 contains p  further examples showing the formation of the acylating agents in the presence of the substance to be acylated, as in Specification 662,573 (see Group IV (c)).  In one of these examples bromacetic acid sulphonic acid is used as starting material.  This subject-matter does not appear in the Specification as accepted.ALSO:The Specification describes but does not claim the process of Specification 662,573, whereby azo-dyestuffs are acylated with a halide of a halo-sulpho-acetic acid.  Examples are given of the process.  The Specification as open to inspection under Sect. 91 contains further examples wherein the halide is formed in the presence of the dyestuff to be acylated, as in Specification 662,573. This subject-matter does not appear in the Specification as accepted.

Filed: 1922-05-20
Abstract: 180,342. Young, A. E., and Naamlooze Vennootschap Apeldoornsche Machinefabriek en Metallgieterij voorheen L. Landaal. May 21, 1921, [Convention date]. Refrigerating, compression machines and processes for; evaporators; cold-accumulators. - In a compression system in which a high pressure evaporator 4 enclosed in a brine tank 5 is connected to a liquid separator 6, communicating with the compressor (not shown) through a pipe 7, and with a low pressure evaporator 9 through a pipe 8, there is provided between the two evaporators an additional communication 11 with a one-way valve 12. The low pressure evaporator communicates with the compressor through a pipe 10, and the pipes 10, 7 are connected by an ordinary cock 14. The high pressure evaporator thus functions as a cold-accumulator, so that when the compressor is stopped a circulation is set up between the two evaporators owing to the temperature surrounding the evaporator 9 being higher than that surrounding the evaporator 4. The pressure of the vapour in the evaporator 9 increases and the vapour flows through the valve 12 to the evaporator 4 where it is condensed, the liquid passing through the separator 6 to the low pressure evaporator. The high pressure evaporator therefore functions as a condenser when the compressor is stopped. Specification 120,923 is referred to. Arrangements of brine tanks and expansion coils functioning as cold accumulators also are described for use with systems other than those necessarily using two evaporators. The Specification, as open to inspection under Sect. 91 (3) (a) refers also to Specification 125,358, [Class 8 (i), Air and gases, Compressing &c.]. This reference does not appear in the Specification as accepted.
