Title: Improvements in or relating to manometers
IPC: G01L7/18
Filed: 1944-11-16
Abstract: 590,078. Manometers. MAY & BAKER, Ltd., and RICH, F. R. Nov. 16, 1944, No. 22751. [Class 106 (ii)] A manometer comprises a tube a closed at both ends, an inner tube b closed at the upper end and open at the lower end to afford communication between the two tubes and a branch tube d so arranged that a charge of indicating liquid such as mercury or oil may be received sufficient always to submerge the open end of the tube b, the tube b forming one limb of the manometer and the second limb being the space between the two tubes. The seal at the upper end of the tube a serves also to close and support the tube b. The tube b is constricted near the lower end in order to prevent a too rapid flow of the mercury. A scale comprising a graduated split cylinder of springy transparent plastic material may be attached to the manometer. For measuring differential pressures, a further branch tube is connected to the inner tube b. The method of charging the manometer with mercury is described.

Title: Improvements in or relating to liquid fuel burners having means for preventing overheating of the burner parts
IPC: G05D23/12
Filed: 1924-09-26
Abstract: 222,497. Cleveland Metal Products Co., (Assignees of Chadwick, L. S.). Sept. 26, 1923, [Convention date]. Burners, attaching, mounting; oil supply.-An oil burner is provided with thermostatic means positioned below the flame and in juxtaposition or metallic contact with the burner parts to reduce the size of flame until overheated parts have cooled down. In the constructions shown, expansion of the thermostat shuts off the oil supply. Fig. 1 shows a burner having a reservoir 4 to which fuel is supplied through a pipe 19 by way of a valve casing 15 having an inlet 17 and outlets 16 and a diaphragm 25 carrying a valve 21 adapted to close the inlet 17 upon the expansion of a bellows thermostat 28 containing a readily-expansible fluid, and situated within the inner tube 1. An adjustable connection 29, 30 between the upper end of the thermostat and a, yoke rising from the valve casing enables the valve to close at different temperatures; in one adjustment the flame is extinguished. In modifications the thermostat is submerged in the fuel in a casing located inside or outside the burner and in one form the valve is adjusted by turning the. casing the neck of which is threaded into an elbow fitting secured to one side of the outer wick tube. In the form shown in Fig. 6, a horizontally-disposed thermostat 50 is situated within the burner, one end being secured to a reinforcing plate 51 and the other adjustably connected through reversely-threaded stems 52, 53 and a sleeve 54 to a flat portion 55 of the inner wick tube, which constitutes a valve co-operating with the inner end of a tubular extension 57 of an elbow fitting 58 leading to the fuel-supply pipe 59.
