A turbine or compressor blade has aerodynamically determined cross-sectional profiles 11, 12 at the tip and root, respectively, and a third cross-sectional profile 13 determined by a simple proportioning method from the first two profiles, the third profile being positioned along the length of the blade so that the opening/pitch ratio at that position corresponds with the design opening/pitch ratio for the cross-section 13, the surface of the blade following a multiplicity of conic section curves, each curve intersecting the profiles. In Fig. 1, the dimension O (opening) over the dimension S (Pitch) plotted against the height of the blade gives a curve 18 (Fig. 2). Arbitrary positions 14, 15, 16 of the intermediate profile 13 are taken and the opening/pitch ratio calculated for each. These give a curve 17 in Fig. 2 and the intersection of the curves 17, 18 gives the correct height for the intermediate section.

Abstract: 840,217. Engine valve gear. YOUNG, D. H. Sept. 9, 1958, No. 28908/58. Class 122 (2). [Also in Group XXVIII] A valve means 9, Fig. 1, for controlling the flow of pressure fluid through the outlet 8 of a piston-and-cylinder dispensing-apparatus comprises a valve stem 16<SP>1</SP>, Fig. 5, engaged by a snap-action spring means 27 operated by a rod 16, the rod and piston 5 having two pairs of co-operating abutments which, when the piston is moved to one or other of two predetermined positions, either open or close the valve. As shown applied to an apparatus for dispensing lubricant, the valve stem 16<SP>1</SP> is formed integrally with the rod 16 and is slidably mounted in a sleeve 18 of polytetrafluoroethylene, which is retained in a bore in the base-plate of the cylinder 1 by a screwed plug 19 ; the valve stem may be formed separate from the rod. The spring means 27, which is of rectangular shape, is secured at its outer ends to the base-plate and.engages, at its inner ends, with a groove 28 formed in the valve stem; the spring may be backed by a plate engaging with a groove 29 in the stem. The opposite end of the rod 16 is provided with a collar 16<SP>11</SP> which moves within a bore formed in the piston and rod 4 thereby providing a lost-motion device. In operation, with the valve in the closed position, pressurized fluid, such as steam, is fed through an inlet 7 and thereby moves the piston 5 against the action of a return-spring 24 until a step 36 on the piston abuts the.collar 16<SP>11</SP> and opens the valve 9 allowing the steam to pass through the outlet 8 into a steam trap 22. Under the action of the spring 24, the piston is moved in the opposite direction and forces the steam in the cylinder 1 through the outlet 8 via ports 20, 21 in the valve stem until, at the end of its stroke, the bottom of the bore in the piston-rod 4 contacts the end of the rod 16, thereby closing the valve. The piston-rod 4 may be adapted to open or close the blow-off valve of a steam boiler.

Title: Transistor radio receivers
IPC: H03G3/00
Filed: 1959-08-24
Abstract: 923,371. Transistor circuits. RADIO CORPORATION OF AMERICA. Aug. 24, 1959 [Sept. 16, 1958], No. 28925/59. Class 40 (6). In a transistor radio receiver, the output of the detector is connected for direct current to a tap on a volume-control potentiometer connected across a D.C. supply while the input of the audio amplifier transistor is connected to another point on the potentiometer, an automatic gain control being derived from the detector and fed in series with the voltage across the potentiometer to the high-frequency amplifier of the receiver and the arrangement being such that variation of the volume control varies the gain control voltage to the highfrequency amplifier without varying the bias on the audio amplifier. In the Figure, a signal is applied from an aerial circuit 8 to a mixer circuit 10 back coupled at 82, 84 to oscillate and so provide an intermediate-frequency output at 12. This is amplified in two stages 86 and 90 and applied to a detector diode 38. One terminal of the detector circuit is connected to the tap on a volume-control potentiometer 50 connected across the D.C. supply and to the base of the transistor audio amplifier 92 the arrangement being such that variation of the volume control setting to control the audio signal does not vary the bias on the transistor 92. An automatic gain control voltage is derived from resistor 46 and applied to the first intermediate-frequency amplifier in series with the voltage at the tapping point on the volume control. Thus, varying the volume setting which varies the bias applied to the intermediate-frequency amplifier and this may reach cut-off value at the extreme setting. Overloading of the intermediate-frequency amplifier is prevented by a diode 88 which becomes conducting when the input signal exceeds a predetermined value. The output of amplifier 92 is supplied to a pushpull power amplifier 70 provided with A.C. and D.C. feedbacks through resistors 99 and 100. In an alternative circuit (Fig. 1, not shown) NPN transistors are used so that the emitters are at earth potential for direct current instead of the collectors as in Fig. 2.

IPC: A01J21/02
Filed: 1951-12-12
Abstract: 708,465. Moulding butter &c. KUSTNER FRERES & CO., SOC. ANON. Dec. 12, 1951 [Dec. 18, 1950], No. 29123/51. Class 87 (2) ,Plastic edible material is forced in measured quantities from a measuring chamber 5 through a die 6 by means of radially disposed members 1, 2, 3. The butter is fed from a hopper to the measuring chamber 5 by means of two intermittently operated parallel screws 24. A blade 3 slides in a cylindrical member 4 which rotates backwards and forwards between two positions in which the blade comes opposite one of two blade-like pusher members 1, 2 which displace the blade in turn. As shown in Fig. 2, the pusher member 1 displaces the blade'3 in such a manner that a quantity B of butter is enclosed between the blade and the pusher 2. The cylindrical member rotates until the blade 3 comes opposite the pusher 2 which has in the meantime been withdrawn (Fig. 3). A fixed quantity of butter, equal to the quantity B, will be thus extruded through the die 6 where it is cut off by means' of an oscillating wire cutter 27 actuated by a cam 28 on the control shaft 7 of the machine. The cutter may carry two wires one behind the other. This shaft also carries a cam 8 which actuates the pushers 1, 2 by means of links 10, 11 and rack-and-segment gears 14, 15. A further cam 31 actuates the cylindrical member 4 by means of toothed segments 21, 22. In order to adjust the amount of butter extruded in each cycle there may be an adjustable amount of lost motion between the segment 22 and the cylinder 4.

Title: Gas turbine installations
IPC: F02C9/18
Filed: 1955-10-13
Abstract: 783,825. Gas turbine plant. LICENTIA PATENT-VERWALTUNGS-GES. Oct. 13, 1955 [Oct. 13, 1954], No. 29173/55. Class 110 (3). A single-shaft gas turbine plant comprises a turbine 1, air compressor 2 and electric generator 7 all mounted on a common shaft, a first heat exchanger 4, a second heat exchanger 10 and a combustion chamber 5. A liquid fuel pump or gaseous fuel compressor 3 is mounted on the turbine shaft, also a speed governor 8. At normal load, air from the compressor 2 is preheated by turbine exhaust gases in the heat exchanger 4; it then passes through the heat exchanger 10 but is not further heated, to the combustion chamber 5. Fuel is supplied from the pump or compressor 3 through the regulating valve 6 to the combustion chamber 5 and gases generated therein pass to the turbine 1 and the exhaust gases therefrom pass through the heat exchanger 4. If the load is reduced, the governor 8 operates to throttle the fuel valve 6 and at the same time to open the gas extraction valve 9, also the by-pass valve 11 and/or the valve 12. When the valve 9 is opened gas flows out of the turbine to the second heat exchanger 10 whereby pre-heated air from the heat exchanger 4 is further heated before passing to the combustion chamber 5. The extracted gas leaving the heat exchanger 10 either passes back through the valve 12 to a lower pressure stage of the turbine or passes through the valve 11 and passes with the turbine exhaust gases to the heat exchanger 4. The valves 6, 9, 11, 12 receive at the same time a temperature-controlled impulse from the gases passing to the turbine inlet, so that the valves only open or close to such an extent that the temperature of the gases at the turbine inlet is substantially constant. The first heat exchanger 4 is not an essential feature of the invention.
