Title: Improvements in Washers and similar Articles for Closures, Seatings for Valves, Pipe Joints, and other purposes, and Means for Attaching and Adjusting them to other Working Parts.
Inventor: COMINGS WILLIAM RIGHTER
IPC: F16K1/46
Filed: 1916-01-11
Abstract: 100,020. Comings, W. R. Jan. 20, 1915, [Convention date]. Valve members and faces; spindles.-Washers for valves, valve seatings, &c., of the type having elastic or mouldable material enclosed in a sheet metal casing in the form of cupped washers or otherwise are provided with means for limiting the pressure of the elastic filling upon the casing-member or members when under compression under working conditions in order to prevent the bursting of the metal casing. In one form, Fig. 1, the washer comprises a pair of telescopic lids B, C secured round the filling A by bending over the edge of the outer lid, with or without a central eyelet, the depth of the inner lid limiting the compression. In some cases a portion of the lower lid is cut away, as in the valve washer shown in Fig. 13, so that both the metal and the filling make contact with the valve seating. In other forms a single lid is used as shown at B, Fig. 29, with a shoulder thereon to limit the pressure; or this shoulder is dispensed with and a shoulder provided on the screw F. In a further form, shown in Fig. 39, the elastic filling is stretched over into an annular ring S which is then secured by a turnedunder lip, or by a double-flanged ring, the filling in this case being under both tension and compression. In some cases stops are provided to prevent the rotation of the washer upon the valve head. The valve facing-washers are secured to the spindles by a spring mouth I, Fig. 45, which engages a flange J<1> on the spindle. A thrust washer F is interposed, and a central opening or recess therein receives the rounded head of a screw F which enables the valve washer to rotate and adjust itself obliquely on to its seating. The mouth I may be formed with spring fingers, and the screw head F may be replaced by a metal ball. The Specification as open to inspection under Sect. 91 (3) (a) describes also the following matter : An arrangement in which the valve spindle is formed with an oval-shaped head so that it can roll obliquely into a socket on the valve washer without springing. In a modification shown in Fig. 56 (cancelled) the elastic filling is dispensed with, a springy seating action being obtained by a V-shaped mouth, as shown, on the outer member B. An elastic pad A is placed between the part C and the thrust washer. The spring mouth may be formed on an independent member attached to the washer, or to the valve spindle. The method of attachment by spring fingers or spring-action mouth can also be applied to secure ordinary washers to valve spindles. This subject. matter does not appear in the Specification as accepted.

IPC: G05D13/00
Filed: 1916-01-13
Abstract: 101,644. Belliss and Morcom, and Guest, C. L. Jan. 13, 1916. Fluid relays.-In a centrifugal governor which acts through a fluid-pressure relay, the relay and its valve are located within, and co-axially with, the boss of the governor bracket a. In the form shown, the boss a has a chamber d containing a piston e attached to a sleeve f connected by a head g to the lever h controlling the throttle &c. The levers c carrying the weights are connected to a hollow piston valve l slidable in the sleeve f and provided with an annular recess m communicating with the interior of the valve. When the weights move outwards, the recess m registers with a port o, so that pressure fluid from the hollow shaft j passes into the right-hand end of the chamber d, while the end of the valve uncovers a port p in the sleeve and connects the other end of the chamber to exhaust through the space between a reduced portion g of the valve and the sleeve and the ports r, .s, u. When the weights move inwards, fluid is admitted to the left-hand end of the chamber, and the other end is connected to exhaust.

The shaft M carrying the arms Ga. I is also provided with an adjustable counterbalance weight. Guide brackets V<1> and sliding brackets V, Fig. 15, on the ends of the lifter plate guide the plate during the spinning traverse, but permit the horizontal movements during doffing. The bobbins are braked by ropes t weighted at w<1>.

Title: Improvements in or relating to radio and the like signal reception
IPC: H03G11/00
Filed: 1933-01-09
Abstract: 409,460. Valve circuits for wireless reception. RADIO RESEARCH LABORATORIES, Inc., 597, Madison Avenue, New York, U.S.A. Jan. 9, 1933, Nos. 759 and 760. Convention dates, April 14, 1932 and June 22, 1932. [Class 40 (v).] In order to reduce the effects of parasitic disturbances in radio reception the signals are impressed on a cold cathode gas or vapour discharge tube having a rising and falling grid voltage-anode current characteristic which only amplifies signals below a predetermined intensity. The embodiment shown in Fig. 1 includes two similar suppressor tubes 1, 20, the former comprising two electrodes 2, 3, the discharge between which serves as the electron source, a grid 5 and an anode 4. The current supply for all the electrodes is a source 10, suitable voltages being applied to the electrodes by the resistances 6-9. The tuned grid circuit 13, 16 is coupled to the aerial circuit 12, 14, 15 and the anode circuit 18 is coupled to the grid circuit 19, 25 of tube 20 which feeds the normal high frequency amplifier 31 of a radio receiver. The characteristic of tubes 1, 20 is of the form shown in Fig. 3, rising from X to Z with an intermediate operating point Y and then falling to D so that signals having an amplitude greater than XZ are suppressed. In a modification regeneration is introduced by connecting the positive side of the source 10 through a resistance-shunted condenser to a variable tapping on the coil 19 (Fig. 2, not shown). The signals may be amplified prior to the suppressor stage, and any harmonics introduced by the latter may be removed by an iron-cored coupling transformer or otherwise. The suppressor stage may be connected to an adapter to be plugged in, in place of an existing high frequency valve in a receiver (Fig. 10, not shown).
