Title: Stator blades for combustion turbines
Inventor: BONFIELD DENNIS HERBERT
IPC: F01D5/18
Filed: 1963-07-18
Abstract: 1,078,116. Turbine blades. BRISTOL SIDDELEY ENGINES Ltd. June 30, 1964 [July 18, 1963], No. 28556/63. Heading F1T. A stator blade for a gas turbine comprises a hollow shell provided with a continuous gap extending over at least the greater part of the length of its trailing edge for the ejection of cooling fluid introduced into the interior of the shell, and a member extending within the shell from a position adjacent to but, at least in the region of the gap, spaced from the trailing edge towards the leading edge and formed so as to provide passages connecting the gap with the interior of the shell. As shown in Fig. 2, the hollow shell comprises a metal sheet 1 having its two edge portions 2, 3, which constitute the blade trailing edge, spaced by a gap 4. A sheet metal member 5 has side portions 7, Fig. 1, extending up to the trailing edge and stitch welded at 8 and 9 to the shell 1. The intermediate part of member 5 is spaced from the trailing edge to form the gap 4 and provided with slots 10, Figs. 1 and 4, through which the cooling fluid flows. The member 5 is shaped at 12 to provide a strut between the sides of the blade. An additional strut member 13 is provided. In a modification, Figs. 5-7 (not shown), the hollow shell comprises two members, the first of which includes the convex side and the leading edge of the blade and integral projections extending towards the concave side of the blade, the projection nearest the trailing edge being formed with a series of slots, and the second of which comprises a curved plate attached to the leading edge and the projections of the first member and having its trailing edge spaced from the trailing edge of the first member.

Title: Improvements in aminobenzyl ethers
Filed: 1950-11-23
Abstract: The invention comprises compounds of the general formula <FORM:0692448/IV (b)/1> in which R is the ether residue from a mono-or polyhydric alcohol, or from the alcohol-ether of polyhydric alcohols, X is hydrogen or methyl and Y is hydrogen, chlorine or the group -CH2R. These compounds are prepared by reduction of the corresponding nitro-compounds, obtainable as described in U.S. Specification 2,587,566.  In an example (1) 3-aminobenzyl glycol ether is prepared by the reduction using a Raney nickel catalyst of 3-nitrobenzyl glycol ether.  Similarly prepared are compounds represented by the above general formula where (i) R represents -OCH2 CH2OH and X represents p-CH3; (ii) X and Y represent hydrogen and R represents -OCH2 CH2OCH2CH2OCH3; (iii) X represents p-CH3, R represents -OCH2CH2OH and Y represents HOCH2CH2OCH2-; (iv) X and Y represent hydrogen and R represents -OCH2CH2OCH2 CH2OH.  The process is said to be applicable to the reduction of ethers formed from chloromethylated nitrobenzene, o-nitrotoluene, 6-chloro-2-nitrotoluene, 4-chloro-2-nitro-toluene, and ethers from 2,4- and 2,6-di-(chloromethyl)-p-nitrotoluene.  Alcohols which may be used in forming the ethers are methyl, ethyl, propyl, butyl alcohols, ethylene glycol, tri- and other methylene glycols, glycerol, erythritol, mannitol and sorbitol, and their partial ethers with e.g. methyl, ethyl and butyl alcohols.

Class 2(2) A polyamide yarn is drawn in two or more stages, the first stage being such that the ratio of drawn length to undrawn length R 1  is determined by the equation R 1 (1+22.2B+284B<SP>2</SP>)=3À60À5 where B is the birefringence of the undrawn yarn. The yarn may be packaged prior to the first drawing stage. A freshly spun polyamide yarn may be drawn in two or more stages, the first stage being such that R 1  is determined by the equation R 1 (1+ 22.2B+ 284B <SP>2</SP>)=4À1  1À1 and the freshly spun yarn may be packaged following the first drawing stage. The areas defined by the above equations include part of the area defined by the equation set out in Claim 1 of the parent Specification, and the areas of overlap are specifically disclaimed. Desirably, the second drawing stage immediately follows the first drawing stage. Preferred polyamides are polyhexamethylene adipamide and polycaproamide and the polyamide yarn may have a second order transition temperature of about 50C. and a force-to-draw transition temperature in the vicinity of 150C. The first drawing step may be conducted at a temperature between the second-order transition temperature and the force-to-draw transition temperature, and the additional drawing steps at a temperature above the force-to-draw transition temperature but below the melting point of the polyamide, preferably at a temperature of at least 20C. below the melting temperature of the polyamide. In a preferred method, the amount in C. by which the, temperature of the first drawing step exceeds the second-order transition temperature is equal to about two to ten times the rate of travel of the filaments into the drawing step in hundreds of yards per minute. Specifications 461,236, 461,237, 576,647 and U.S.A. Specifications 2,289,377 and 2,533,013 also are referred to.

Abstract: 1,076,060. Temperature control of electric soldering irons. WELLER ELECTRIC CORPORATION. July 6, 1965 [Feb. 9, 1965], No.28691/65. Heading G3R. The heating element 36 of an electric soldering iron is supplied through a step-down transformer 16 and silicon controlled rectifier 29 the conducting periods of which are automatically varied, to maintain constant the temperature of the soldering tip, by a gate control circuit comprising another silicon controlled rectifier 23, a thermistor 28 in thermal communication with the soldering tip and a potentiometer 22 adjustable to obtain a desired tip temperature limited by a resistor 27. With the potentiometer setting at its maximum temperature position, the value of resistor 27 necessary to limit the tip to a desired maximum temperature is determined, the tip temperature being measured with a thermocouple and potentiometer arrangement which is subsequently used to calibrate the control dial of potentiometer 22. System stability is improved by mounting rectifiers 23, 29 in the handle of the iron, Fig. 1 (not shown) with rectifier 29 in heat-dissipating contact with the metal portion thereof. In operation the rectifiers 23, 29 conduct in each appropriate half cycle for a period corresponding to the extent of the deviation of the tip temperature from the desired value.

Title: Improvements in or relating to the manufacture of shoes
IPC: A43B23/08
Filed: 1926-11-16
Abstract: 290,519. British United Shoe Machinery Co., Ltd., Mellerio, L. P., and Lund, W. J. Nov. 16, 1926. Stiffeners.-Thermoplastic stiffeners for boots and shoes consist of blanks charged with thermoplastic material which is capable of losing its thermoplasticity under suitable treatment. For instance, synthetic resins may be incorporated cold in a pulp of fibrous material prior to that material being felted in a paper making machine. On the other hand cloth or other fibrous material may be charged with the stiffening agent or mixture by impregnating the same with a solution of the agent or mixture in a volatile solvent or with an emulsion or suspensicn of the agent in a liquid, and then drying the impregnated material. Instead of a synthetic resin being used as the impregnated material, a thermoplastic mixture containing it may be applied to a sheet of fibrous material already charged with an ordinary thermoplastic stiffening compound. A still hot sheet of fibrous material impregnated with ordinary thermoplastic material may be passed over or in contact with a block of synthetic resin so that a coating of the resin is taken up by the fibrous material and chilled. The synthetic resin as powder may be dusted on a still hot sheet of thermoplastic material. Other materials than synthetic resin may be used. Drying oils amalgamate readily with resinous and like materials and diminish the thermoplasticity as oxidation or drying advances and by the use of well known drying accelerators. A marked change of thermoplasticity may be obtained by a minimum of heat treatment. Again ordinary resinous stiffening agents may be dusted over while still tacky with slaked lime which causes an appreciable loss of thermoplasticity under the above conditions. The invention is not restricted to treatment of toe puffs prior to incorporation in the shoe. A hot puff stitched into an upper might be coated with synthetic resin. In such a case the heating to which tho shoe would be subjected to for lasting and other operations would serve to initiate the curing of the synthetic resin.
