Title: Improved tableting press
IPC: B30B11/10
Filed: 1934-05-30
Abstract: 440,335. Moulding tea &c. tablets by rotary-mould-table machines. ELLING- TON, N. B., and HYDRAULIC ENGINEERING CO., Ltd., Charles Street, Chester. May 30, 1934, No. 16166. [Class 87 (ii)] A press for moulding tablets or briquettes from powdered or granular material such as tea, coffee and the like comprises a rotary table a carrying dies b having plungers c connected to common crossheads d, hydraulic rams e adapted to engage the crossheads d and so press material in the dies, means for intermitently rotating the table to bring a die alternately to a hopper f and a ram e, and valve means operated by a motor through differential gearing for controlling and timing the operations. The table is rotated by a hydraulic ram g connected to a chain h attached to a ring i having pawl and ratchet connection with a central boss of the table. The ring is also connected by a cord h<1> to a weight g<1> which rotates the ring freely about the boss and draws up the ram g when it is connected to exhaust. The ram g is arrested by a stop before the table has finished each rotary movement and the table proceeds by its own momentum until it is arrested by a stop k engaging one of four projections k<1> on the table. The stop k is moved into or out of engaging position from the projections k<1> and a snap catch k<2> also engages the table to prevent backward movement. As the ram g is connected to exhaust, the rams e are connected to pressure and vice versa. There may be four sets of six dies b and two hoppers f and rams e. The plungers d are held in the pressing position by detents s which are released when a cam s<1> engages a lever s<2>. The tablets are ejected when a cam t engages a roller t<1> and are swept away by a barrier or scraper mounted above the table. The hydraulic connections are controlled by a valve l, Fig. 3, operated by a spindle l<1> connected to a double lever m which is engaged by a cam m<1> on the casing of a differential. The spindle l is moved in one or the other direction to make the valve connections to supply pressure to the ram e or to the ram g according as one or the other arm of the double lever is engaged by the cam m<1>. The differential is rotated from an electric or other motor when a ratchet wheel o on one shaft n<1> of the differential is held by detents o<1> or v. The detent o<1> is engaged or released by a lever o<2> operated by a pawl p<1> on a spindle p2 and the detent r is released to engage the ratchet by a cam on the shaft n<1>. The spindle p<2> abuts against and is moved by a projection on the snap catch k<2> as that engages the table.

Title: Method of and apparatus for quantitative analysis
IPC: G01N27/26
Filed: 1975-04-21
Abstract: 1510174 Fluid constituent analysis PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 21 April 1975 [24 April 1974] 16380/75 Heading G1N In a continuous quantitative determination of one or more fluid constituents, the output of a detector responsive to the constituent is maintained constant by addition of the constituent to the fluid. The constituent is either added in the necessary amount or a fixed amount is added and the amount of fluid reaching the detector controlled. The control signals, which also provide the desired measure, are derived by comparing the detector output with a reference and using the difference signal to drive a control signal generator. The detector may be coulometric, optical, chemiluminescent or magnetic. As shown in Fig. 2, fluid to be analyzed flows from inlet 2 to outlet 8 via detector D and flow control device 28. The detector output is compared at 12 with a reference voltage Er and the difference drives controller 15. Flow control device 30 takes fluid from branch 29 and passes it through filter 31 which removes the constituent(s). A known constituent concentration from source 20 enters the resulting fluid and the resulting reference solution is passed via paths 32 and the parallel path containing variable flow control 33 and constituent filter 34 to the incoming fluid at 24. The control signal from 15 controls flow control 33 to control the concentration of reference solution reaching branch 24. In the embodiment of Fig. 4, reference solution from source 20 enters the incoming fluid and the resulting fluid passes either along path 36 or via controlled flow control 37 and constituent filter 38 to detector D. The reference voltage may be derived by adding a known concentration of the constituent to the fluid after the constituent normally present has been removed. Detector drift can be compensated by alternately supplying a known proportion of the detector input and the reference solution to a second detector and controlling the reference concentration to minimize the A.C. output of the detector. Various circuit modifications and methods of connecting to fluid input and output are described.

Title: Process for the manufacture of thiourea compounds
IPC: C07C335/22
Filed: 1933-06-12
Abstract: Unsymmetrical thiourea derivatives are prepared by first condensing one molecular proportion of a compound halogen--CO--R--NCS (R representing a phenylene residue) with one molecular proportion of an aromatic aminocarboxylic, aminosulphonic or aminosulphocarboxylic acid in an aqueous medium containing an acid other than a mineral acid, and then reacting the product in equimolecular proportions with ammonia or a primary or secondary amine in a neutral or weakly alkaline medium. In this way the halogen of the above phenylene compound reacts in the first stage, and the thiocyanate group in the second.  The products are useful in the manufacture of dyestuffs. Examples are given of the interaction of (1) m-phenylmustard oil-carboxylic acid chloride first with 1 : 8-aminonaphthol-3 : 6-disulphonic acid and then with m-aminobenzoic acid; (2) m - phenylmustard oil-carboxylic acid chloride first with 2-aminonaphthalene-5 : 7-disulphonic acid and then with m-aminobenzoic acid, or first with m-aminobenzoic acid and then with 2-aminonaphthalene-5 : 7-disulphonic acid; (3) m-phenylmustard oil-carboxylic acid chloride first with aniline-3-sulphonic acid and then with m-aminobenzoic acid; the intermediate product may be isolated; (4) m- or p-phenylmustard oil-carboxylic acid chloride first with 1-aminobenzene-2 : 5-disulphonic acid and then with 4-nitraniline-3-sulphonic acid; (5) p-phenyl-mustard oil-carboxylic acid chloride first with m - aminotoluyl - m - aminobenzoyl - 1 - naph - thylamine-4 : 6 : 8-trisulphonic acid and then with 3<1> - aminobenzoyl - 2 - naphthylamine - 5 : 7-disulphonic acid.  The samples are prepared by treating phenyl-isothiocyanate-m-carboxylic acid chloride first with p-sulphanilic acid and then with either ammonia, aniline or methylaniline.  The formul  of the products are given.  m-Aminotoluyl - m - aminobenzoyl - 1 - naph - thylamine-4 : 6 : 8-trisulphonic acid is obtained by condensing m-nitrobenzoyl chloride with 1 - naphthylamine - 4 : 6 : 8 - trisulphonic acid, reducing the nitro group with iron and acetic acid, condensing with m-nitrotoluylic acid chloride and reducing the nitro group.  3<1> - Aminobenzoyl - 2 - naphthylamine - 5 : 7 - disulphonic acid is prepared by condensing 3-nitrobenzoyl chloride with 2-naphthylamine-5 : 7-disulphonic acid and reducing the nitro group.  Arylmustard oil-carboxylic and sulphonic acid halides.  The carboxylic acid halides are prepared by treating aromatic aminocarboxylic acids with phosgene and converting into the halides.
