Title: Improvements in and relating to wall cooling arrangements for combustion chambers
IPC: F23R3/00
Filed: 1949-01-19
Abstract: 672,780. Generating combustion products under pressure. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 19, 1949 [Jan. 22, 1948] No. 1516/49. Class 51 (i). Cooling and insulating means for the wall of a combustion chamber comprises a plurality of circumferentially spaced longitudinal rows of axially-spaced openings in the wall adapted to admit comparatively cool fluid into the combustion space, and a plurality of deflector means secured to the inner surface of the wall and spaced therefrom so as to define restricted openings for discharging a thin film of cooling and insulating fluid across adjacent parts of the inner surface. The wall 3 of the flame tube in Fig. 1 is perforated by holes 7 for admission of combustion air and by holes 8 for admission of cooling and insulating air, and deflectors 9 are located over the holes 8, within the flame tube. The deflectors are secured by tabs 9a and " dimples " 9b, which are welded or otherwise secured to the inner surface. Some cooling air is also directed in paths 16a over the adjoining deflector thereby cooling it. The deflectors in Fig. 7 comprise longitudinal strips 19 having holes 20 located over holes 18 in the wall of the flame tube and secured by the " dimpled portions 21. The holes 20 are of smaller diameter than the holes 18 so that some air passes straight through the two holes to the interior of the flame tube for combustion, while the remaining air is deflected over the inner surface of the flame tube for cooling. Corrugations 22 are formed in the strips 19 for expansion purposes. In Fig. 4, deflectors 11 are located on the interior of the end dome 5, behind air inlet openings 10, the adjacent deflectors overlapping by a substantial amount. The dome 5 is covered by a shroud 12 having an air inlet opening 13, so as to prevent gases in the flame tube flowing outwardly through the openings 10 which might occur on account of the high air velocities, and therefore low static pressure, around the exterior of the dome. Proportions for the various dimensions are given. Specifications 637,223 and 639,617 are referred to.

Title: Intermittent vacuum regulator
IPC: G05D16/06
Filed: 1960-01-19
Abstract: 937,068. Surgical drainage. CHEMETRON CORPORATION. Jan. 19, 1960 [Jan. 26, 1959], No. 1965/60. Class 81 (2). A device for producing a cyclically interrupted vacuum for surgical drainage purposes comprises a vacuum-operated motor which alternately connects a source of vacuum to the motor itself and to an outlet which is coupled to the drainage bottle. The motor comprises two bellows 44, 46 connected together through a restricted orifice 48 and filled with oil. The bellows 44 is enclosed within a chamber 40 so that when this is evacuated, bellows 44 expands and 46 contracts at a rate depending on the flow of oil through the orifice 46. The end plate of bellows 46 is connected by a linkage with a slide valve 32 and, when this is in the position shown, vacuum, applied to pipe 16, is connected by pipe 36 and through the valve 32 to the chamber 40. The bellows are consequently drawn upwards until the valve is moved over to its upper position, against stop 60, where the vacuum through pipe 36 is connected through pipe 34 to the outlet 14, which leads to the vacuum bottle. At the same time, the chamber 40 is vented to atmosphere and the bellows system 44, 46 is drawn outward by a spring 56. Vacuum regulators 20, 18 are connected to the ducts 16, 14, respectively, to prevent the application of an excessive suction to the patient and, in addition, adjustment of the regulator 20, by determining the degree of vacuum in the chamber 40, controls the rate at which the bellows return to their upper position and thus the proportion of the cycle during which suction is applied to the bottle. The regulators comprise diaphragms which are normally balanced by spring pressure but which, on the application of a rarefaction in excess of the set value, are drawn upwards to close the corresponding suction pipes.
