Abstract: 533,027. Fastenings operated by fluid pressure. HAYNES, L. L., and STANTON, R. S. Aug. 3, 1939, No. 22490. [Class 44] A bolt of the kind retracted by spring and shot by fluid pressure comprises a bolt 5 mounted in an extension 2a of a cylinder 2 in which a piston 1 slides, a rod 4 on the piston slidably engaging in a bore in the bolt. A spring 7 retracts the piston and a weaker spring 8 retracts the bolt, the pressure applied to the piston being transmitted through spring 7 to both bolt and spring 8. The arrangement allows a door to be fastened by slamming after the bolt has been shot. As shown, pressure is supplied from a pump 11 driven from a sprocket 12 as described in Specification 533,028, [Group XXVIII]. Pressure fluid is supplied through duct 14a, control valve 13, and duct 3 to cylinder 2. The valve comprises a piston 14 urged to the left by spring 15 so that ,when the pump supply ceases, an annular duct 16 exhausts duct 3 through duct 17. When pressure is applied, piston 14 is urged to the right to cut off exhaust and connect ducts 14a, 3. Other pressure supply arrangements may be used, and more than one bolt may be operated from the same pressure source, for example for locking railway carriage doors.

Abstract: 417,691. Vapour generators. BRITISH THOMSON HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Nerad, A. J. ; 1061, Glenwood Boulevard, Schenectady, New York, U.S.A.) Aug. 12, 1933, No. 22577. Convention date, Aug. 12, 1932. [Class 122 (iii).] Comprises a vapour generator particularly for use in mercury-steam power plants. A plurality of heating elements are arranged to form a plurality of combustion chambers, the walls of which comprise vapour-generating tubes and the gases from which pass to a gas chamber containing further heating-elements. In a horizontal arrangement, an intermediate chamber is arranged between the combustion and gas chambers. The heat-absorbing surfaces are large in comparison with the dimensions of the entire apparatus. Combustible material, e.g. pulverized coal and primary air, is fed to burners 8. Mercury-containing drums and heating-elements 9, 10 are arranged in the interior of the furnace. The vapour passes to headers 12 connected to the turbine 13. The exhaust passes to a condenser-boiler wherein steam is generated which is superheated in a coil 22 in the furnace uptake. The furnace gases pass through an air preheater 24. Combustion takes place in chambers 27, 28, 29 of small cross-section defined by heating-elements 10. These each comprise an outer corrugated wall 31, Fig. 3, and tubes 32 embedded in a copper casting 33. Clearance is provided to permit expansion and equalize combustion in the chambers. Tube extensions 35 lead to conduits 36, and conduits 37 connect lower headers 19. The conduits and drums are connected by external pipes 39, 39a. The gas chamber contains a plurality of tube groups each comprising four tubes connected to a separate header. Complete combustion is effected in the intermediate chamber 46. In a modification the gas chamber is arranged above the combustion chamber.
Patent GB-601597-A (GB)
Title: Improvements in or relating to radio obstacle detectors
IPC: G01S1/02
Filed: 1944-11-15
Abstract: 601,597. Cathode-ray oscillographs. STANDARD TELEPHONES & CABLES, Ltd. Nov. 15, 1944, No. 22632. Convention date, Sept. 5, 1942. [Class 37] [Also in Group XL (c)] A reference marker for a cathode-ray tube indicator particularly applicable to radar is produced by varying the intensity or focusing of the beam for a short period at the required point so as to produce a dot on the trace line. The reference marker may be moved along the trace by a calibrated control from which, in the case of radar, the distance represented can be read directly. In a pulse radar apparatus of known form (Fig. 1, not shown), in which the echo pulse from a distant object appears on the screen as an indication such as shown at 42 a pulse in synchronism with the transmitted pulse is passed through a calibrated adjustable delay device and applied to the beam intensity control element or the focusing control element of the tube to produce a spot such as at 40. If the delayed pulse is applied to the intensity control element it will provide a spot by momentarily increasing the brilliancy of the trace, alternatively it may be passed through a pulse inverter before being applied to the control element, in which case the spot is a dark one produced by decreasing the light intensity. The size of the spot is controlled by applying the delayed pulse to the focus control electrode. If the delay is increased, the spot 40 is moved along the trace line 27 towards the echo pulse indication 42. When it reaches the indication it will travel up the left-hand side, and, as the height is many times greater than the width, a small movement in the delay control, representing a very small distance along the direction of trace line 27, will produce a considerable movement of the spot up the side of the echo pulse indication which thus acts to give a magnified movement of the spot just where required for accurate adjustment. Precise manual following of any movement of the object represented is thus made easier, the spot being maintained on the peak of the indication as at 45. It is stated that the variable delay device may be directly connected to gun controlling equipment. Specification 571,772, [Group XL], is referred to.
