Abstract: 1,188,985. Analytical test pack. E.I. DU PONT DE NEMOURS & CO. 18 April, 1967 [26 April, 1966], No. 17677/67. Heading B1X. An analytical test pack comprises a container formed from pliable polymeric material, the container being divided into one or more closed compartments 10 (Fig. 1) or 24 (Fig. 4) and a reaction chamber, means communicating with the reaction chamber for introducing the test sample, the compartments 10 or 24 being independently openable into communication with the reaction chamber, and at least one compartment containing an analytical reagent. In the embodiment of Figure 1, compartments 10 are formed as depressions in one of two sheets of polymeric material used to make the container, the sheets being bonded together in the areas surrounding each depression and around their peripheries, the bonded areas between the compartments and the reaction chamber 28 being rupturable by manual pressure. The means for introducing the test sample comprises rigid header 13, having cylindrical channel 14 through it and opening (15) to its outside, the header being bonded to one of the sheets of polymeric material. Cartridge 18 inserted into channel 14 has passage 21 which communicates via hole (15) in header 13 and an opening in the adjacent sheet of polymeric material with the reaction chamber. The test sample may be injected through hole 16a in header 13 and through stopper 20 into channel 21. Alternatively the sample may be injected through hole 16b into the main part of tube 18 and there treated, for example with ion exchange resin and/or by filtration through a partition 23 before flowing into the reaction chamber. In the embodiment of Figure 4, clips 25 are used to close the reaction compartments, and the means for introducing the test sample comprises flexible tube 22 sealed between the two sheets of polymeric material. Examples relate to determining urea in blood serum using 1-cysteine hydrochloride, sodium salts of alpha-ketoglutaric acid and of dihydrobetadiphosphopyridine nucleotide, alpha-glutamic dehydrogenate and urease; determination of dehydrogenases (lactic acid, malic acid and alpha-hydroxybutyric acid dehydrogenases) using the corresponding acids, beta-nicotinamide adenine dinucleotide, phenazine methosulphate and 2, 6-dichlorophenol indophenol; determining glucose in e.g. blood serum using glucose oxidase, peroxidase and 3, 3<SP>1</SP> dimethoxybenzidine hydrochloride; determining glutamic-oxalacetic or glutamic-pyruvic transaminases in blood serum using beta nicotinamide adenine dinucleotide, phenazine methosulphate, 2, b-dichlorophenol indophenol, 1-glutamic dehydrogenase, alpha-keto glutaric acid, 1-aspartic acid and 1-alanine. For the latter determination, cartridge 18 is loaded with polyacrylamide gel and the sample injected into this and washed through into the reaction chamber with phosphate buffer.

Abstract: 827,410. Cables. PIRELLI S.p.A. June 4, 1957 [July 14, 1956], No. 17685/57. Class 36. A method of impregnating and sheathing an oil-filled cable includes coiling the unsheathed cable core on to a drum within an impregnating tank which rotates about a horizontal axis and connecting to each end of the core an end fitting constructed to allow passage of oil therethrough to the core oil duct and adapted to be connected to a hawser for pulling the cable core and for supplying heating current to it. The core on the drum 11 within the tank 1 has the end fittings applied, hawsers being connected to each end fitting and to through terminals fitted on the tank (the hawser 29 and terminal 8 at the outer end only being shown) and current is supplied to dry out the core. The tank has an inclined top and funnel 6 sealed by a cap 7; after impregnation of the core with oil the cap 7 is removed and the terminal 8 disconnected from the hawser 29 so that the cable may be pulled out through the spout 6. An expansion bellows is connected between the spout outlet and a sheathing press; the oil supply to the tank is increased to cause overflow into the bellows and thence the press and the cable is drawn through by means of the hawser, the lead sheath thus being extruded on to the end fitting as well as the cable core to hermetically seal the cable end. The end fitting is constructed so that surplus sheathing may be cut off, the hawser disconnected and an oil reservoir connected. The fitting at the other end of the cable is sealed by a suitably constructed plug. Constructions of end fittings for single and three-core cables are described.

Title: Railway Signalling System.
Inventor: PAGANINI ETTORE
IPC: B61L3/22
Filed: 1916-12-15
Abstract: 102,953. Paganini, E. Dec. 23, 1915, [Convention date]. Track apparatus actuating signals on trains; signalling to and communicating between trains and cabins and stations.-Currents are transmitted along the track rails from cabins to trains and energize sensitive relays carried by the train and connected through collectors to the two rails. These relays control bells or other signals or train stopping devices. Telephones may also be used and signals may be transmitted between fixed points. Fig. 3 shows both a signal device f controlled by a sensitive relay l, and a telephone receiver h on the train, the connexion being made to the rails bv shoes e. In the cabin are a telephone transmitter g, a change-over switch, and also an interrupter c. To give two distinct signals, a polarized relay on the train may be used in conjunction with a pole-changing switch at the transmitting-station. The arrangement shown in Fig. 6, including a differential relay v, is intended to indicate failure of the contact shoes or connexions. A current passing through both coils of the differential relay in series from the track rails or current from the battery a passing through one coil only, as when one shoe leaves the rail, causes the contact c to close and operate the signal f. In the case of long lengths of track with low insulation, the circuit is divided into sections, as shown in Fig. 9, each section controlling the section next to it by means of a relay s', s<2> controlling a contact u, t. Relays s', s<2> may be polarized.

Title: Twisted tube with a polygonal, preferably rectangular cross section, and method of an d apparatus for the manufacture thereof
IPC: B21D11/14
Filed: 1959-05-27
Abstract: 863,198. Making tubes and waveguides; twisting. HOLLANDSE SIGNAALAPPARATEN N.V. May 27, 1959 [May 28, 1958], No. 18068/59. Classes 83 (2) and 83 (4). Twisted tube of a polygonal, e.g. rectangular, cross-section is made by welding or soldering together separate parts of its wall, each of such parts being made by clamping the two ends of a plate to relatively rotatable clamps, the position of the plate relative to the axis of rotation of the clamps being the same as its position relative to the axis of the tube of which it is to form part, and relatively rotating the clamps to twist the plate while it is backed by a plurality of elements positioned between the clamps and freely rotatable about the axis of rotation of the clamps. All four plates forming the wall of the tube may be twisted simultaneously on the same apparatus or two diametrically opposed plates may be simultaneously twisted. A plate to be twisted is clamped at one end on to a block 121, by a clamping plate 122, 123 or 124 bolted to the block and held parallel thereto, and at its other end on to a block 118. The block 118 is carried by a yoke 117 and the block 121 by an arm 115 rotatable on a yoke 108. The plate held by the clamps is backed by flat supports 120, freely rotatable on a shaft 116 extending between the clamps, and separated by tubular spacers 119. The clamp 121 is rotated to twist the plate by a nut 113, on a threaded bar 110, bearing against the arm 115. During twisting the yoke 117 moves axially along bars 102, 128 against springs 104, 130 bearing against adjustable abutments 105, 131 on the bars, longitudinal play of the spacers 119 on the shaft 116 permitting such movement, although one spacer 119 may be replaced by a helical spring. The blocks 118 and 121 and the clamping plates are rounded off at the edges so that the plate to be twisted is not sharply bent adjacent the blocks. After twisting, four plates are assembled in the apparatus and provisionally welded at a few points. The welded tube is then removed and welded or soldered along the complete length of the adjacent edges of the plate. The twisted tube may form part of a waveguide connection.
Patent GB-689852-A (GB)
Title: New derivatives of 20-oxo-pregnanes and manufacture thereof
Filed: 1950-07-19
Abstract: The invention comprises thioacetals and thioenol ethers of 20-ketopregnanes which are substituted in the 21-position (e.g. by a free or functionally converted hydroxy group), and the manufacture thereof by treating a 20-ketopregnane, substituted in the 21-position, with a mercaptan and, if desired, treating the resulting thioacetal, if acyclic, with a mercaptide-forming heavy metal derivative to split off mercaptan and form a thioenol ether. The starting materials and products may also be further substituted, e.g. by free or functionally converted keto or hydroxy groups (e.g. acyloxy or alkoxy groups) in the 6-, 7-, 12- or especially the 3- or 11-positions, by epoxy groups (e.g. in the 3 : 9- or 16 : 17-position) or by halogen atoms, and may contain double bonds (e.g. in the 3-, 4-, 5-, 11- or 16-position). The production of the thioacetals is advantageously effected with alkyl or aralkyl mercaptans, or ethylene dimercaptan, in the presence of acid catalysts and an organic solvent (preferably an excess of the mercaptan).  The conversion of the acyclic thioacetals to thioenol ethers may be effected with oxides or inorganic or organic salts of mercury, cadmium, silver, copper, lead, bismuth, cobalt or nickel, preferably with exclusion of water and if desired, in the presence of organic or inorganic acid-binding agents.  If an acid anhydride is used as solvent, p  free hydroxyl groups present may be simultaneously esterified. The products are useful as therapeutic agents or intermediates thereof.  In examples: (1) D 5-3 : 21-diacetoxypregnene-20-one is stirred with ethyl mercaptan in carbon tetrachloride at 0 DEG  C. in the presence of hydrogen chloride to produce its diethyl thioacetal; (2) D 5-3-oxy-21-acetoxypregnene-20-one is similarly treated, but using dioxane as solvent and with the addition of anhydrous calcium sulphate; (3) 3 : 21-diacetoxyallopregnane-20-one is reacted with ethyl mercaptan in chloroform at 20 DEG  C. in the presence of hydrogen chloride; (4) 3 : 21-dioxy - 12 - acetoxypregnane - 20 - one is stirred with ethyl mercaptan in the presence of hydrogen chloride; (5) the product of (1) is refluxed with mercuric chloride and cadmium carbonate in ethanol and the product is reacetylated with acetic anhydride and pyridine to give D 5-3 : 21-diacetoxypregnene-20-one-thioenol ethyl ether; (6) and (7) the same product is obtained from the same starting material by heating with mercuric chloride in pyridine and acetic anhydride; (8) the foregoing reaction is effected by heating with copper acetate in acetic anhydride and glacial acetic acid; (9) the product of (3) is treated as (3) is treated as in (6); (10) the product of (4) is similarly treated, yielding 3 : 12 : 21-triacetoxypregnane-20-thioenol ethyl ether.
