Abstract: 172,064. Drayton, N. D. Grimke-, and Tooth, L. F. July 30, 1920. Regulating compression.-A by-pass valve in a gas-compressing plant, constructed to open automatically upon failure of the gas supply, is loaded partly by the gas pressure, failure of the supply permitting the valve to open and preventing collapse of the meter employed. In the apparatus shown, a casing h, the sides h<3>, h<4> of which are connected with the inlet and outlet sides of the compressor, contains a differential valve comprising an upper piston a having a depending sleeve a<1> formed with ports a<2> through which the gas passes when the piston rises, and a lower piston b working in a sleeve h<2> within a cylindrical portion of the casing. The lower end of the valve spindle passes through a gland d fitted with loose packing into a casing e wherein it is secured to a diaphragm e<1>. The space below the piston b is connected by a tube k with the low pressure side of the valve casing, to maintain equal pressures therein. The diaphragm is subjected to the pressure of the gas supply, which may be regulated by a governor, through a connection l, and on failure of the supply, the air pressure within the valve casing lifts the valve, allowing gas to pass freely. Failure of the gas supply may be indicated by a pilot jet fitted to the diaphragm casing g as at g<1>, or by a pressure gauge used alone or in connection with an audible alarm.

Abstract: 379,498. Paper-making machines. BELOIT IRON WORKS, 815, 2nd Street, Beloit, Wisconsin, U.S.A. Aug. 13, 1931, No. 22895. Convention date, Jan 24. [Class 96.] In a Fourdrinier paper-machine having jointed table roll rails and shake transmitting mechanisms therefor, the amplitudes of the shake motions are individually adjustable while both the machine and the motions are functioning. Table rails 20 supporting table rolls 26 and formed in sections 33, 32, 31 connected by tongues 38 and grooves 39, are resiliently supported on side beams which can be displaced laterally to remove the table roll frame from the machine. Adjacent the couch roll (not shown), pivots 34 prevent vibration of the outer end of the sections 33 of the table rails when shaking devices 44 applied to the other sections and the breast roll cause them to vibrate. The shaking devices, which are described in Specification 354,751, are adjustable while the machine is in operation to vary the amplitude of the vibration between zero and a predetermined maximum and are removably secured to standard 46, the arrangement allowing them to be moved as an integral part of the table frame. To this end, the driving motor 47 is provided with separable coupling members 82, 83 which connect it to the driving shaft 53 of the shaking devices. The motor may also drive, through the shaft 53, a similar shaking device for the breast roll 27. In modications, a separate synchronous motor drives the breast roll shaker or each shaker has a separate motor, the motors being arranged in synchronous pairs of which those for the breast roll shaker and the adjacent one constitute one pair. By driving the motors from a motor generator set, the speed of the motors and, consequently, the frequency of the vibrations may be varied. The invention allows a body of stock to flow on to a travelling foraminous surface to which is imparted at spaced points in its travel a lateral vibratory movement of varying amplitude and speed in accordance with the type of stock being run and the desired characteristics of the web.
