Title: Telemeter for taking direct measurements of horizontal distances with a horizontal or a vertical staff
IPC: G01C3/12
Filed: 1935-10-14
Abstract: 464,288. Surveying instruments. ALT, H. Oct. 14, 1935, No. 28342. Convention date, Oct. 12, 1934. [Class 97 (ii)] A telescope is aimed at a mark at one end of a horizontal or vertical staff, clamped, and a fine adjustment effected by a micrometer screw, whereupon the telescope is rocked by a second micrometer screw, through a predetermined angle modified in accordance with the inclination of the telescope so that the intercept on the staff corresponds to the horizontal distance between the staff and telescope. Fig. 3a shows a fitment to adapt a telescope for use with a horizontal staff. A block M carrying a micrometer screw B engaging a member V may be clamped to the vertical axle of the telescope when the latter has been roughly sighted on the staff mark. The member V carries a micrometer screw A which engages the horizontal circle L of the telescope and serves to set the latter accurately on the staff mark. Spring plungers F keep the parts V and L pressed against the screws B, A. The screw B is then moved axially through a constant distance determined by abutments, whereupon the telescope is moved through an angle the intercept of which on the staff is independent of the inclination of the telescope axis. When the length of the staff subtends an angle less than the angle defined by the full movement of the screw B, the latter is rotated until the telescope has swung over the total length of the staff whereupon the screw A is used to bring the telescope back to the initial position and the length of the'staff again traversed by rotating the screw B and so on till the full movement of the screw B has been effected. Alternatively the head of the screw B may have a hundred graduations and the number of graduations corresponding to a traverse of the complete staff length determined. The number of staff lengths intercepted by the predetermined angle may then be calculated from the number of graduations corresponding to the full movement of the screw B. Fig. 8 shows a telescope adapted for use with a vertical staff. H is a lever fixed to the telescope F and engaging a roller W on a slide K<1> which can be manually slid along a bar S until the telescope is roughly adjusted on the staff mark and clamped. The bar S is moved on the guides M to effect a fine adjustment by rotating the nut A and the guides M together with the bar S are moved by the micrometer screw B to cause the telescope to move through the desired parallactic angle. A spring C keeps the bar S pressed against the nut A and the supports M pressed against the screw B.

Filed: 1975-07-09
Abstract: 1485338 Producing thermosetting resin powder paint DAI NIPPON TORYO CO Ltd and JAPAN STEEL WORKS Ltd 9 July 1975 [11 July 1974] 28873/75 Heading B5A A thermosetting resin surface coating powder is obtained by extruding a molten composition 1 of the resin, Fig. 2, and forming it into a sheet during passage through the nip of rollers 2, 3, and cooling the sheet in passage around cooled rolls 3, 3<SP>1</SP>, or 3, 3<SP>1</SP>, 3<SP>11</SP>, from which the cooled sheet is delivered by take up rolls 5, 5<SP>1</SP>, or pulverizing means. The pass of the composition through the rolls may be vertical, or horizontal as shown. A roll 4 may be provided to maintain contact of the sheet with the roll 3. The roll 2 is horizontally adjustable and the rolls 3<SP>1</SP>, 3<SP>11</SP> are horizontally and vertically adjustable. The peripheral speed of the rolls 3, 3<SP>1</SP>, 3<SP>11</SP> is generally equal to that of roll 2, but the speeds of the rolls 3<SP>1</SP>, 3<SP>11</SP>, and 5, 5<SP>1</SP>, are independently adjustable. The temperature of the rolls 2, 3, 3<SP>1</SP>, and 3<SP>11</SP>, is controlled by circulating cooling water, or coil. In the Fig. 4 embodiment, guide plates 23, 24, are provided for the sheet, and further cooling by air delivered from a plurality of nozzles 19, 20, which may be laterally adjustable for different sheet widths and may also be of adjustable spacing from the rolls. The pulverizing may be effected by an air stream pulverizer, after crushing by a roll crusher, to produce an average particle size of 40 to 60 Á. The resin may comprise epoxy, unsaturated polyester, acrylic, or urethane formed by blocked isocyanates, and the composition may include colouring, extender, and rust preventing pigments, dyestuff, curing agent, and flowability adjusting agent. The composition is kneaded, heated, and melted in a machine delivering to the extruder from which the composition is extruded. A prior art process, Fig. 1 (not shown), is referred to in which the rolled sheet is delivered along a conveyer to a granulator. The example relates to an epoxy resin composition treated by the present process in comparison with prior art processes. The powder paint may be electrostatically applied to a steel plate to form a film which is then heated.

Abstract: 323,744. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Oct. 8, 1928. Converting pulsating currents into steady continuous currents.-A wireless receiver incorporating a mains supply apparatus has the highfrequency and detector stages built as one unit, and the low-frequency stage and the mains supply apparatus combined to form a second unit, the two units being finally mounted in the same casing. The cathodes of the high-frequency and detector valves are indirectly heated, and signal volume is controlled by regulating the grid bias of the high-frequency valves. Fig. 1 is a circuit diagram, and Fig. 2 an elevation of the receiver, showing two high-frequency stages I, II, and a detector stage D forming one unit; and a lowfrequency stage E and mains supply apparatus G forming the second unit, the dotted line N dividing the apparatus of the two units. The various voltages are derived from a supply apparatus, which comprises a transformer T, rectifier G, smoothing-condensers 75, 76, 78, 80 and resistances 62, 63 in series with a choke coil 64. The full positive voltage is applied to the plates of the amplifier valves I, II, E; and the remaining positive voltages are taken from a potentiometer bridge comprising resistances 77, 79, 39, 22 and 21. In this way the screen voltage for valve II is higher than that for valve I, and a reduced plate voltage is applied to the detector D. Grid bias is applied to the output valve E from a fixed tap on the choke 64, and to the high-frequency valves from a slider on the resistances 63, which enables volume to be controlled. A secondary coil 81 on the supply transformer T energizes the filament of the output valve E, and the heating-elements of the indirectly-heated valves I, II, D.

Title: Improvements in and relating to printing blocks and rollers
IPC: B41C1/14
Filed: 1931-10-19
Abstract: 375,168. Printing-surfaces. UHER, E., 2, Ottostrasse, Augsburg, Germany, and UHER ENGINEERING CO., Ltd., Glarus, Switzerland. Oct. 19, 1931, No. 28988. Convention date, Oct. 23, 1930. [Class 100 (ii).] A printing block or roller consists of a porous non-metallic support or backing, capable of resisting compression and distortion, a top metal layer which is pierced according to the picture, and a very thin intermediate metal layer permeable to the ink or other colouring medium and firmly adhering to the printing side of the backing. The ink or colouring medium is applied under pressure from the back of the block or roller. The backing may be of pumice-stone, artificial stone, or porcelain, and the intermediate metal layer may be a noble metal such as silver. The metal layer may be applied directly to the porous backing by cathodic dispersion. For example, a warm, hollow, porcelain roller is placed upright in a vacuum chamber having a pressure of about 0À11 mm. of mercury, and silver wires of about 0À1 to 0À2 mm. thickness are placed at equal intervals around and about 5 or 6 cm. from the roller, the wires being cathodes in a circuit of from 1000 to 1500 volts and 0À5 amperes. Another method of depositing the intermediate metal layer consists in evaporating the metal by heating, distillation, or sublimation, and condensing it on the backing. The intermediate metal layer is then given a top coating of metal, such as copper, by an electrolytic or other process, so as to render the block or roller practically wholly impervious to the ink or other colouring medium. The top layer is then pierced according 'to the picture it is desired to print, by photochemical or other means.

Title: Manufacture of substituted pyrimidones
Inventor: LACEY RICHARD NORMAN
Filed: 1950-11-29
Abstract: Substituted pyrimidones of the general formula <FORM:0699812/IV (b)/1> (wherein R represents hydrogen or an alkyl or aryl radical, X an alkyl, aryl, -NHR1 or -SR2 group, R1 hydrogen or an alkyl radical and R2 an alkyl radical) are manufactured by reacting diketene with an amidine, guanidine or isothiourea of the general formula <FORM:0699812/IV (b)/2> or with a salt thereof if the reaction be effected in the presence of an alkaline material.  The reaction is desirably carried out in a diluent medium, which should be a solvent for the second reactant, such as water, an organic solvent (e.g. an alcohol, ether, ester, ketone, aromatic hydrocarbon, or chlorinated hydrocarbon), or an aqueous organic solvent, and may take place at temperatures in the range -10 DEG  to 60 DEG  C. (e.g. at room temperature).  When X represents -SR2, the product may be hydrolysed to the corresponding uracil and mercaptan.  In examples: (1) and (2) diketene is shaken with benzamidine hydrochloride in aqueous caustic soda or with benzamidine in water to produce 2-phenyl-4-methyl-6-pyrimidone; (3) diketene is stirred with guanidine carbonate in aqueous caustic soda to yield 2-amino-4-methyl-6-pyrimidone; (4) the same product is obtained by reacting guanidine hydrochloride as in (1); (5) S-methylisothiouronium iodide (from thiourea and methyl iodide) similarly yields 2-methylmercapto-4-methyl-6-pyrimidone; (6) diketene is stirred with acetamidine hydrochloride in ethanol in the presence of sodium ethoxide to form 2 : 4-dimethyl-6-pyrimidone; (7) to (9) diketene is stirred with N-phenyl-S-methylisothiourea in ethanol, ether, chloroform, acetone, dioxan, benzene or ethyl acetate, and an intermediate product which is formed is converted with alkali to 2-methylmercapto-1-phenyl-4-methyl-6-pyrimidone; (10) diketene is stirred with N : S-dimethylisothiouronium iodide in aqueous caustic soda to given 2-methylmercapto-1 : 4-dimethyl-6-pyrimidone; (11) diketene is allowed to stand with methylguanidine hydrochloride in aqueous caustic soda to produce 1 : 4-dimethyl-2-amino-6-pyrimidone; (12) a solution of sodium in ethanol is added to a solution of methylbenzamidine hydrochloride in ethanol, the precipitated sodium chloride is removed, diketene is added and the solution allowed to stand, producing 1 : 4-dimethyl-2-phenyl-6-pyrimidone.  Other starting materials specified are propionamidine, phenylacetamidine (R = H, X = C6H5CH2-), N : N1 - dimethyl - guanidine, phenylguanidine, N - methyl - N1 - phenylguanidine, S - ethylisothiourea and N - phenyl- and N-methyl-S-ethylisothiourea.

Abstract: 1439603 Film evaporation UNITED KING- DOM ATOMIC ENERGY AUTHORITY 18 June 1973 [22 June 1972] 29396/72 Heading B1B A film evaporator plant has at least one metal tube exterior as an evaporating surface supporting a filament whose surface wettability with reference to water is less than that of the evaporating surface, and distribution means for applying a heating fluid into the bore of the tube, the intersection of the surface of the tube exterior and the filament supported thereby forming at least one cavity which acts as a nucleation site when a film of liquid is applied to the tube exterior. A method of evaporating a liquid e.g. aqueous comprises flowing a film of the liquid over a plane evaporating surface bearing a filament whose surface is substantially less wettable by the liquid than the material of the evaporating surface, the filament cross section normal to its longitudinal axis being such that nucleation sites are formed at positions where the surface of the filament intersects the evaporator surface and applying heat to the evaporator surface remote from that bearing the filament to boil liquid from the film. The filament may be in the form of a mesh, and may be of polypropylene or copper supported on a copper alloy evaporating surface, or may be of surface oxidised copper wire supported on a nickel-copper alloy evaporating surface.
