摘要： 816,073. Pressure gauges. MECHANISM Ltd. Sept. 3, 1957 [Sept. 3, 1956], No. 26873/56. Class 106 (2). A pressure-gauge comprises a pressuresensitive capsule 1, a spring-loaded contactcarrying member 5 displaceable by the capsule 1, a micrometer 16 carrying a contact 13, and an electronic circuit, not shown, incorporating a cathode-ray tuning indicator of the type having a fluorescent anode, the making and breaking of the contacts 8, 13 sharply varying the pattern viewed. on the screen of the cathode-ray indicator. The micrometer 16 is graduated in millibars and is used to adjust the position of contact 13 relatively to the contact 8 carried by the spring-loaded lever 5. The apparatus is enclosed in a casing 20 provided with a window for viewing the screen and with a nipple 18 for connection to a pressure source. In operation, the micrometer 16 is adjusted as required until the pattern viewed on the screen is just on the point of changing, and the pressure read from the graduations on the micrometer. For calibration, the nipple 18 is connected to a source at a standard pressure, but in normal use it is left unconnected, thus equalizing the pressure inside the casing 20 with the ambient atmospheric pressure. Excessive expansion of the capsules 1 is prevented by a plate 22 secured to the casing 20.

摘要： 771,902. Pressure gauges; indicating apparatus. MECHANISM, Ltd., and GRANDIDGE, J. E. Nov. 29, 1955 [Feb. 14, 1955], No. 4363/55. Classes 106 (2) and 106 (4). The indicating movement for a diaphragm pressure gauge comprises a rotary driver 5, Fig. 1, driving e.g. by means of a contrate quadrant 6, Fig. 2, and pinion 7, the spindle for the pointer 9, a lever 4 fixed to the driver 5, and a push-pull link 3 connecting the lever 4 to the diaphragm 1, preferably by means of an arm 2 parallel to the plane of the diaphragm, pivot-pin joints being provided to allow for the arc of the lever. The effective lengths of the arm 2 and lever 4 may be adjustable, and the lever 4 may be angularly adjustable relatively to the driver 5. Stop means 11 may be provided to affect the effective area of the diaphragm after a predetermined movement to provide a non-linear scale.

摘要： 556,564. Air speed indicators. MECHANISM Ltd., and WRIGHT, G. E. July 2, 1942, No 9164. [Class 106 (ii)] A pressure responsive indicating device such as an air speed indicator has two concentrically mounted indicators arranged to traverse a common scale plate bearing two distinct scales, each indicator being independently actuated by a common fluid pressure. One of the indicators has a limited range of operation while the other responds only at higher pressure. In the form shown in Figs. and 2 pressure from a Pitot tube or similar device is led to a cylindrical chamber 1 with metal bellows 4, 5 mounted on the end walls. The more sensitive of the bellows 5 has its movement limited by a hollow sleeve 6 through which passes a rod 8 attached at its outer end to an adjustable radius arm 9 on a shaft 10. The shaft 10 carries an arm 11 with a rack 12 engaging a pinion 20 on a spindle 21 to which a pointer 25 is attached. The less sensitive bellows 4 has a rod 7 bearing on or attached to a leaf spring 14 which contacts with a cam surface 15 and a hook shaped arm 16 on a shaft 17. The shaft 17 has an arm 18 with a rack 19 engaging a pinion 22 on a hollow spindle 23 surrounding the spindle 21 and carrying a pointer 26. The pointer 25 traverses a dial 24, Fig. 3, with an outer scale representing tens of miles per hour and the pointer 26 cooperates with an inner scale calibrated in hundreds of miles per hour. A shield or plate 27, 28 is provided to mask whichever pointer is not operative.

摘要： 1,012,708. Indicating-apparatus. MECHANISM Ltd. June 25, 1964 [May 3,1963], No. 17653/63. Heading G1J. Apparatus for measuring the rate of change of one variable with respect to another comprises a drum 16 rotating at a constant speed, a lever 12 moved about its pivot 13 in response to the pressure in a capsule 10, a castor roller 15 pivotally connected to the lever 12 and contacting the drum 16 so that as the lever 12 moves the castor 15 longitudinally of the drum 16 the castor will pivot and move a pointer 20 against a scale 21 to indicate the rate of change of the pressure with respect to time. The castor roller 15 is rotatably mounted in a frame 14 pivoted on the lever 12 and the castor action is obtained by offsetting either the pivotal axis or the drum axis from alignment with the roller axis and can be increased if none are aligned. The drum 16 could be replaced by an endless belt or by a toroid. The pointer 20 may be adapted to record and may be included in a control warning system of apparatus being monitored.
