Title: Improvements relating to turbine rotor blades
IPC: F01D5/28
Filed: 1948-07-09
Abstract: 660,007. Turbine blades. BOLSEZIAN, G. July 9, 1948 [July 9, 1947], 18504/48. Class 110(iii) In a hollow turbine blade formed of an assembly of at least three elements one of which is an at least partly inner element and at least two of which are outer elements in contact with the hot gas, the outer elements form an empty space around part of the at least partly inner element through which cooling medium flows and every leading edge or portion of the leading edge and every trailing edge or portion of the trailing edge has both its front and back faces on the same element. The blade, Fig. 1, comprises three blade elements 1, 2 and 4. The element 1 is integral with the rcot 3 and the element 2 is secured at its outer end to the rod or support 4 by means of a rivet 5 or welding. The rod 4 is secured to the root by a screw connection 12 or a dovetail. The rod 4 is isolated from the hot parts 1 and 2 by the provision of a space 7, through which cooling air supplied through ports 10 passes. This cooling air exhausts through slots 11 and blows off the boundary layer. To damp vibration in the blade, there is a friction fit between the interengaging end portions 8, 9 of the parts 1, 2. The element 2 may be formed in two halves of ceramic material which are separated by longitudinal gaps 11, Fig. 2. The two halves are assembled at their outer ends by a metallic cup member and at their inner ends by the blade element .1. In a modification. Fig. 4, the blade consists of two outer elements 25, 26 and a partly inner element 22 which is longer than the outer elements. The elements 25, 26 which form the blade profile are separated by a gap 29 and are assembled by a weld 28. Cooling air supplied through the conduit 30 exhausts through the outer end of the gap 23. In Another modification, Fig. 6, the blade is formed by a partly inner element having a core 37 which is integral with the root and the leading and trailing edges 45 and 46 of the blade. Two outer elements 42, 43, formed by profiled sheets are attached to the core 37 by welds 44: so as to form cooling air spaces 40, 41. The Specification as open to inspection under Sect. 91, comprises also a blade similar to that described with reference to Fig. 4 except that the parts 25, 26 are formed integral with one another and are attached to the root of the inner element 22. In another embodiment, the blade is also similar to that described with reference to Fig. 4 except that the two outer elements each constitute one face of the blade. In a modification of the arrangement described with reference to Fig. 6, the blade is formed from a single casting and the cooling air spaces 41, 42 may be divided into two or more passages. It is also stated that the internal surfaces of the elements 1, 2 and or the external surface of the rod 4 may be polished or provided with a polished stainless metal surface coating of nickel, chromium or platinum. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,011,416. Liquid-heating boilers. R. GOSSALTER. May 16, 1962 [May 16, 1961], No. 18811/62. Heading F4A. An oil-fired boiler arranged for the heating of at least one liquid has a horizontal doublewalled fire tube 7 surrounded by a wall 6 of generally frusto-conical shape forming the inner wall of a liquid heating compartment and an outer casing 1 spaced from a surrounding the external cylindrical wall 4 of the liquid compartment. The combustion gases flow through the fire tube 7, then in the reverse direction in the annular space surrounding the tube 7 and finally, after a second reversal, through the annular space between the outer casing 1 and the outer cylindrical wall 4 to a flue pipe 12. The liquid space as shown is subdivided by an internal cylindrical wall into two heating systems, one for hot tap water and the other being connected to a closed space heating system 25. Water for the latter enters the boiler at 18 and flows downwardly in the pipe 20 into the annular space 17 which communicates at the burner end with the interior of the fire tube 7 and with the outlet connection 24. Tap water enters the remaining space around the partition wall 6 at 26, a baffle plate 28 diverting the incoming stream of cold water to prevent erosion of the wall 6. To prevent resonant vibrations of the tubular parts the fire tube 7 and the partition wall 6 may be mounted eccentrically (Fig. 2, not shown). In a modification (Fig. 3, not shown) the boiler is provided with two double-walled fire tubes one inside the other.

Title: Apparatus for carrying out welding or coating of metals and chemical reactions electrically
IPC: B23K9/32
Filed: 1935-07-04
Abstract: <PICT:0459446/III/1> <PICT:0459446/III/2> In an apparatus for effecting chemical reactions either alone or during coating of a metallic surface with a metal, of the kind having one or more hollow electrodes d carrying a container a for pulverulent material to be reacted, the container has a perforated bottom c and is connected with an apparatus such as a drop hammer or electrical vibrator for shaking the bottom to prevent obstruction to the feed of the powder melting at the nozzle.  The powder is melted by electric resistance by a current of 5--10 volts.  The water-cooled electrode d may be connected at i to one terminal or two electrodes and containers may be connected to the opposite terminals with the work electrically dead, and in a further form, two electrodes and containers and the work may be connected to the terminals of a multiphase circuit. Protective gas may be supplied from a pipe l.  In the first form, when effecting chemical reactions alone, the work may be replaced by a substratum of electrically conductive material such as graphite which may be lined with a thin plate of iron &c.  The electrode may be of carbon or high fusing point metal or carbide, such as tungsten carbide or may be of iron with a cooling means.  The electrode may have a tubular liner of high melting point metal such as tungsten, molybdenum, or tantalum, which may be fed forward as consumed, or may contain a thin rod connected thereto by depressions therein.  In the latter case the end of the nozzle may be of non-conducting material such as sintered corundum.  The apparatus may be enclosed in a gas-tight container through which a protective gas such as hydrogen is passed.  As an example of a chemical reaction, a mixture of 93 per cent of powdered tungsten and 7 per cent of powdered carbon may be converted into tungsten carbide by melting or sintering.

Abstract: 1,178,926. Programmed control of electro-erosion. EXPERIMENTALNY NAUCHNO-ISSLEDOVATELSKY INSTITUT METALLOREZHUSCHIKH STANKOV. April 26, 1967, No.19244/67. Heading G3N. An electro-erosion machine is controlled by a digital programme fed in parallel-series into an electronic memory unit of a code convertor controlled in dependence on a step-wise variation of the voltage across the erosion gap. As shown, information from a reader 1 is fed in parallel-series mode to a memory 2, comprising flip-flop registers, connected to selection units 4, 5 of a decode multiplier 3. The outputs of the multiplier are connected to averaging units 14-16 connected through commutating units 21, and reverse units 20 to stepping motors 19 positioning a wire electrode with respect to a workpiece. A master oscillator having a pulse rate pre-set in dependence on the type of machine is connected through an AND-gate 8 to the multiplier 3. The AND-gate is controlled in dependence on the voltage across the erosion gap 10 through a measuring circuit 24 and a shaper 11 comprising a Schmitt trigger, so that when the gap voltage falls to a set value, the shaper 11 is triggered to close the AND-gate 8 and inhibit the passage of pulses from the oscillator 6 to the multiplier 3 and consequently stop the relative movement between electrode and workpiece, until depletion of metal by the electro-erosion process causes the gap voltage to rise above the set value. Since pulses from the master oscillator my coincide with the output of the shaper 11, a shaper 13, having a longer pulse duration than that of a shaper 12 at the output of the oscillator 6, is provided at the output of the AND-gate 8.
