Abstract: 1,141,372. Valves. A. S. VOLPIN. 17 Aug., 1966, [11 April, 1966] No. 36916/66. Heading F2V. An automatic sealant sealed valve comprises a valve body 10 having a chamber 13 in which a gate valve is reciprocated. In the fully open and closed positions, a recess in the gate connects a sealant supply passage to circular grooves in the valve seat. The sealant is supplied from a reservoir 36 by a piston 39 having a rod 40 which extends outside the casing. The lower face of the piston is subjected to the pressure in the chamber. During opening and closing movement, pistons in the gate are moved by the pressure in the chamber and, when the gate is fully opened or closed, the sealant forced by the piston causes the fluid in the sealing grooves to move these gate pistons to purge the sealant grooves, such material being discharged during the next open or closing movement. The seating members are also urged towards the gate by the sealant acting on a rear face of the seating.

Title: Method and apparatus for determining the course of aircraft by means of the acoustically measured elevation and azimuth of the aircraft
IPC: G01S1/72
Filed: 1934-12-24
Abstract: 449,610. Locating sounds. HARLAS, J., POHANKA, R., and TECHNICKY PRUMYSL AKCIOVA SPOLECNOST, 80, Kraloyska, Prague. Dec. 24, 1934, No. 36989. [Class 118 (ii)] The course of an aircraft and the angular position of a target towed by the aircraft are deduced by means of the apparatus shown wherein a pair of shafts 1, 3 rotate in accordance with the acoustically determined azimuth and elevation angles #a, #a. A drum 2 which rotates with the shaft 1 is displaced by a block 5 which engages in a function groove in a drum 4 on the shaft 3, with the result that a fixed pencil 6 traces on the drum 2 the curve of log cot #a plotted against #a. It is shown that the angle of slope # of this curve is equal to #a+ alpha, where alpha is the course angle. A transparent disc 7 having a diametral base line is rotated automatically from the shaft 1 through #a and is further rotated by means of a handle 12 to bring the base line tangential to the curve. This further rotation is indicated by a pointer 13 and gives the course angle. The apex angle #, that is, the elevation angle of a plane through the course and the observation station, is given by tan # sin #=tan #a. On a drum 14 therefore are plotted a series of curves of #a against # for different values of A. The drum 14 is rotated through # from a gear-wheel 9 controlling the disc 7, while a pointer 16 is moved vertically in accordance with #a from the shaft 3 and determines the apex angle #. The corrections in #a, #a for a target at a distance d behind the aircraft are shown to depend on the quantity Q=v @v - d@e/y @ sin #a, v, c being the velocitios of the aircraft and of sound, and y the estimated or predetermined height. A drum 44 bears curves of dc/y sin #a against #a for different values of y. A pointer 42 is set from the shaft 3 in accordance with #a, and the drum is rotated to bring the pointer on the appropriate curve by a handle 46 through a differential 45. The value of v is inserted in the differential 45 by a handle 47 so that the shaft 21a is rotated through Q. An arm 18 on a shaft 20c is turned through # from the shaft 19, while a screw spindle 20 carried by the arm is rotated through Q + w from the differential 21 so that a nut 22 thereon is at a distance Q from the axis of the arm 18. A connecting rod 24 carried by the nut passes through a slide block 25 capable of rotation about axes M, N and mounted on a frame 26 which is turned through #a about the shaft M<1>. The movement of the rod 24 is transmitted to a parallel pointer 29 of which the lateral and vertical deflections give the required correction in #a and the corrected value of #a. By inserting #a from the shaft 1 by means of a handle 36, the corrected value of #a is obtained. Electrical transmitters 38, 41 may be controlled in accordance with these values.
