Title: Improvements in or relating to triple expansion steam engines
IPC: F01B17/04
Filed: 1927-11-25
Abstract: 292,022. Norberg, E. Nov. 25, 1927. Compound &c. engines; engines with reciprocating cylinders; tandem-cylinder engines. - A triple expansion engine is provided with high, intermediate-and-low pressure pistons 30, 33, 27, 35 connected in pairs by rods to reciprocate in opposite directions and drive a three-throw crankshaft 5. The pistons 30, 33 reciprocate in cylinders 31, 40 secured to the opposite sides of a central partition 1. The pistons 27, 35 reciprocate in the cylinder 3 and have cylindrical extensions working over piston heads on the cylinders 31, 40. The piston 30 is connected by rods 29 to the piston 27 which operates the central crank 6. The piston 33 is connected by a rod 34 to the piston 35 which bv a rod 37, crosshead 38, guided, return rods 24, and connecting- rods 21, operate cranks 7 oppositely disposed to crank 6. Main steam is supplied to the inner ends of the cylinders 31, 40 by an eccentric-, operated, spring-pressed oscillating valve 13 arranged in the partition 1, Fig. 6. The pistons 30, 33 have spring-opened, lift valves 53; the pistons 27, 35 have two rings of opposed, circumferentially-arranged, spring-opened lift valves 46, 48. The ends of the cylinders 31, 40, 3 respectively have transfer ports 41, 51, and the pistons 27, 35 have ports 52, Fig. 8, which register with the ports 51, Fig. 3. The lift valves are closed by spring-mounted tappets. In operation, the valves 53 being closed by the tappets 55, steam enters the cylinders 31, 40 and forces the pistons outwards. At the end of the outward stroke, steam passes through slots 41 into the extensions on the pistons 27, 35. The springs open the valves 53. The steam presses the pistons 27, 35 outwards and returns the pistons 30, 33 in their cylinders. When the ports 51, 52 register, steam passes to the ends of the cylinder 3, cushions the pistons 27, 35, the valves 46 open, the return stroke of the pistons 27, 35 begins, and also a new stroke of the pistons 30, 33. As the pistons 27, 35 move inwards after the ports 51 are closed, the valves 48 open and the cylinder ends exhaust through the valves, the body of the cylinders 3, and the main exhaust 5.

Title: Improvements in turbines
IPC: F04D27/02
Filed: 1946-10-29
Abstract: 617,734. Steam turbines. AKTIEBOLAGET GOTAVERKEN. Oct. 29, 1946, No. 32079. Convention date, Jan. 25. [Class 110 (iii)] [Also in Group XXXIV] The main valve 4 of an exhaust steam or other turbine is moved to the position in which it admits steam to the turbine and closes the byepass 7 to the condenser by a servomotor 8 subject to the pressure oil of the lubricating system. The oil is normally delivered by a gear-wheel pump 11 driven from the turbine. For low-speed running, at which the delivery pressure of the pump 11 would be insufficient to keep the valve 4 open, a second pump 25, electrically driven, comes into operation. The delivery pressure of this pump is less than the normal pressure of the pump 11 so that, at full speed, its non-return delivery valve 29 remains closed and the pump discharges to source through a valve 30. Oil from the pumps 11, 25 passes to the servomotor through a restricted opening in a non-return valve 21 and a drain 24 is controlled by an emergency governor. For starting, a hand pump 19 may be used to fill the lubricating system and to open the main valve 4. Lubricating oil passes through a cooler 17 and pipes 18 and used oil is drained to the tank 13 by pipes 32, 33. The turbine 1 drives a compressor 2 for inter-stage re-compression of the steam in the main engine which exhausts to the turbine 1.

Abstract: 1479673 Television ELECTRICITE DE FRANCE (SERVICE NATIONAL) 19 July 1974 [19 July 1973] 32100/74 Heading H4F An isometric map showing the physical characteristics of a three-dimensional test object 1 with respect to a reference is produced by projecting an optical grid pattern R on to the object the basic luminous structure (light striations) of which is operated upon to form an image containing irregularities which correspond to differences between the physical characteristics of the test object with respect to the reference, this image being formed (a) by optically superimposing the striated image of the test object with a similarly derived striated image from a reference object (Fig. 2, not shown), i.e. object comparison, or (b) by vibrating the test object and integrating the resulting striated images over a period of time (e.g. using a high remanence television pick-up tube 4) so as to obtain a reference system of striations superimposed on the instantaneous striated image of the test object, i.e. test object vibratory condition analysis. The image is scanned by a television camera 4 and the resulting video signal is filtered by a band-pass filter 7, the central band frequency of which corresponds to the frequency of the carrier wave of the modulation signal, this frequency being a function of the scanning rate and the spacing between the flat parallel uniformly spaced beams of the striated system. The modulated carrier signal from filter 7 is then demodulated 8 and displayed in a CRT 9 controlled by synchronizing signals 13 separated at 6.

Title: Improvements in or relating to arrangements for synchronising a telegraph transmitter and a receiver
IPC: H04L7/02
Filed: 1961-09-07
Abstract: 938,876. Automatic phase control systems. SIEMENS & HALSKE A.G. Sept. 7, 1961 [Sept. 7, 1960], No. 32220/61. Class 40 (5). A telegraph receiver is synchronously controlled by phase comparing an A.C. derived from the receiver rotary mechanism with an incoming synchronizing A.C. of equal frequency or synchronizing pulses derived from the telegraph pulses. Further, the phase detector output voltage is automatically reversible in polarity so that synchronizing takes place either with the receiver and the synchronizing A.C. in phase or anti-phase, depending on which receiver phase is nearest the initial unsynchronized condition. In Fig. 3 a rectangular A.C. synchronizing waveform from an amplifier V is differentiated at D to produce positive pulses operating a relay R and contacts r1, r2 so that the sharp edges are sampled of a rectangular wave of equal period derived by frequency dividers T1, T2 and phase shifter P from a crystal oscillator Q. Positive and negative control voltages are therefore produced across smoothing networks R3, C1 and R2, C2, depending on phase error if any of the push-pull output of T2, which through threshold devices S1, S2 alter the frequency division ratio of T1 until correct phase is restored. Further, if the outputs of T2 and V are initially mainly in anti-phase relation a phase detector M produces a negative D.C. output operating through a relay U and contacts u1, u2 to reverse the phase of the push-pull output from P so that the system stabilizes on the nearest synchronous condition (in phase or anti-phase relation). In Fig. 4 two rectangular reference waves differing in phase by 90 degrees are derived by frequency dividers T1, T2, T3 from oscillator Q and applied to phase detectors M1, M2 receiving inputs from an incoming rectangular A.C. synchronizing signal of equal frequency. One detector M1 applies its output D.C. control voltage through smoothing circuit R1, R2, C and amplifier S to a motor M adjusting as necessary a phase shifter Ph between the oscillator Q and output of T1 until correct phasing is produced. Detector M2 produces a D.C. output reversing if necessary through relay U and contacts u1, u2 the polarity of the output of M1 so that the system stabilizes at the nearest phase quadrature relation of the two inputs to M1, irrespective of their actual phase sequence. Alternatively, for both Figs. 3 and 4, the receiver reference A.C. or synchronizing A.C. can be reversible in phase, instead of the control voltage as in Fig. 4.
