Abstract: 1,218,122. Gas turbine combustion apparatus. MINISTER OF TECHNOLOGY. June 4, 1969 [June 10, 1968], No.27396/68. Heading F1L. A flame stabilizing device, e.g. for the reheat or bypass duct of a gas turbine engine, comprises a tube 4 of substantially circular cross-section with a protuberant trailing edge portion. When flame stabilization is not required, suction is applied to the interior of the tube 4 to act through holes 6 on the gas flow past the tube, thus resulting in minimum disturbance in the flow as shown in Fig. 3b. The suction is shut off when flame stabilization is required, resulting in a flow pattern as shown in Fig. 3a with recirculation zones. A fuel supply tube 3 is mounted upstream of the tube 4, the tubes being in alignment and supported by a common strut 1. The tubes 3, 4 may be striaght or may form an annular array, Fig. 1 (not shown). In the latter arrangement three sets of annular tubes 3, 4 are supported concentrically at different radii by means of three equi-angularly spaced radial struts 1, fuel being supplied to the tubes 3 through pipes. The trailing edges of the struts 1 may be shaped to define flame spreading zones.

Title: Improvements in or relating to transfer valves for refrigeration systems
IPC: F25B41/04
Filed: 1956-09-07
Abstract: 809,618. Valves. CARRIER ENGINEERING CO. Ltd. Sept. 7, 1956 [Jan. 3, 1956], No. 27510/56. Class 135. A transfer valve for refrigerating systems operating under a reversible cycle comprises a valve body 20 having three interconnected compartments 21, 22, 23 of which the end compartments each have an inlet and a port spaced therefrom and the intermediate compartment 22 has an outlet 32. One end compartment is of greater cross-sectional area than the other. A valve device within the body selectively connects the outlet 32 with the port in one of the end compartments and simultaneously prevents communication between that port and the inlet of that end compartment and also prevents communication between the outlet and the other end compartment. As shown, the valve device comprises a pair of pistons 36, 37 of unequal diameter connected by a rod 38. The compartment 23 has a port 31 and an inlet 28 and the smaller piston 36 moves therein between seats 27, 30. Similarly the compartment 21 has a port 33 and an inlet 29 and the larger piston 37 moves therein between the position shown and a seat 24. To enable both pistons 36, 37 to seat accurately on their respective seats 30, 24, a spring-loaded collar 42 in a recess 39 provides a limited degree of lost motion. In place of the lost-motion device, the upper piston 36 may be arranged to seat on a resilient member. The refrigeration system comprises a compressor 10, a condenser 13, a refrigerant expansion device 14, and an evaporator 15. The outlet of the compressor is connected directly to the inlet 28, and indirectly to the inlet 29 through a normally closed solenoid valve 18. The ports 31 and 33 are connected to the condenser and the evaporator respectively. The parts are shown in the position for normal refrigeration. To reverse the cycle, the valve 18 is opened, and high pressure fluid from the compressor acting on the larger piston 37 raises the whole piston assembly cutting off the port 31 from the inlet 28 and connecting it to the port outlet 32 and at the same time disconnecting the port 33 from the outlet 32 and connecting it to the inlet 29. Thus the functions of the condenser 13 and the evaporator 15 are reversed.

Title: Improvements in resistance welding
Inventor: WALLER DAVID NEVILLE
IPC: B23K11/10
Filed: 1963-07-11
Abstract: 1,014,133. Welding by pressure. BRITISH WELDING RESEARCH ASSOCIATION. July 7, 1964 [July 11, 1963], No. 27566/63. Heading B3R. In a spot, stitch or seam resistance welding process, weld quality is ascertained by comparing the rate of separation of the electrodes 12, 13 due to expansion of the work 10, 11 during an initial portion of the welding operation with rates of electrode separation for which weld quality is known. The top, copper electrode 12 is pressed against the work by compressed-air acting on a piston 15. A rack 17 moving with electrode 12, turns a pinion 19 which, through friction discs 23, Fig. 2, pivots a contact lever 24 against an upper contact 25c on a micrometer head 26. A foot-switch 20 starts the welding operation, and a timer 21 controls the welding current supply. Pulses from an oscillator 27 connected to the welding transformer 14 are, fed to a counter 28, Fig. 3, counting being initiated by a pulse from the transformer. The time is thus recorded for expansion of the work to move the lever between the contact 25c and a lower contact 25d. If this is less than a pre-set time T1, a circuit 30 indicates that too high an expansion of the work has occurred; if it is between T1 and T1+T2, a circuit 31 indicates that an acceptable weld will result, and if it is longer than T1 + T2, a circuit 32 indicates that the expansion rate is too low. Circuits 30, 32 can be used to give an audible warning or to stop further welding, and with circuit 31 they can be used with an external recorder. As shown, circuits 30, 32 are connected to a circuit 35 for automatic correction of weld quality. Circuit 35 adjusts the amplitude of the electrodecurrent by altering the firing angle of an ignitron circuit 36. Instead of effecting the adjustment during the welding operation, it may be made at the end. Mild steel and stainless steel may be welded. Instead of measuring the average rate of electrode separation over a predetermined distance, the rate of separation could be continuously measured during the initial period of the welding operation.

Abstract: 430,560. Heating systems and apparatus. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Sept. 27, 1934, No. 27736. Convention date, Sept. 27, 1933. [Class 64 (ii)] A temperature-control device suitable for use with a piezo crystal comprises a closed chamber containing a fluid which is kept in the condition of saturated vapour by the application of heat to a part of the chamber. In Fig. 1, a condenser 10 is connected by a tube 12 to a vaporizer 11 of relatively small volume, and a chamber 14 to contain the object to be maintained at constant temperature is secured to the top of the condenser. The apparatus is surrounded by insulation 17. The vaporizer 11 is heated by steam or electricity, and in the latter case a bimetallic snap-acting switch control may be provided to maintain the temperature in the vaporizer sufficiently high to vaporize all the liquid. The fluid employed, e.g. sulphur dioxide or difluordichlormethane is introduced in such quantity that when wholly in the state of saturated vapour, the desired temperature is obtained. To prevent direct transmission of heat from the vaporizer to the chamber 10, the tube 12 may be of low conductivity and of small cross section. In a modification, Fig. 2, not shown, two chambers may be maintained at different temperatures with the same heating element. The temperature maintained in the condenser 10 may be varied by varying the volume of the condensing space by means of an adjustable bellows in the wall, Fig. 3, not shown, or by adjustably inclining the condenser so as to provide a pocket of variable volume to retain condensate from returning to the vaporizer, Fig. 4, not shown. In another form, Fig. 5, not shown, the apparatus is not inclined, but some of the condensate returning to the vaporizer is trapped in a receptacle having an overflow of variable height. The temperature maintained in the condenser varies slightly with changes in the ambient temperature, and to obtain a more sensitive control the condenser 90, Fig. 7, is enclosed in another condenser 94, the temperature in which is maintained practically constant by a heater 95 as described above. The heater 95 and also the heater 91 of the inner chamber 90 receive heat from a constant temperature chamber 100 operatng in a similar manner in conjunction with a vaporizer 101. In a modified apparatus for correcting for changes in ambient temperature, Fig. 8, not shown, a condensate trap similar to that of Fig. 5, is varied in volume by means of a thermally sensitive actuating device subject to such ambient temperature.
