IPC: F04B9/14
Filed: 1918-02-04
Abstract: 122,887. Carey, R. F. Feb. 4, 1918. Stroke, varying; regulating delivery by opening suction and delivery valves.-In hydraulic pumps and like apparatus, in which the capacity is varied either by varying the stroke of the piston or by altering the position of the valve &c. in relation to the crank &c. used for reciprocating the piston, the capacity-varying means is actuated by an apparatus comprising both hydraulic and mechanical actuating-means. In one form, the apparatus comprises a cylinder 1 containing a piston 2 provided with a tubular rod 3, which is connected by a link 5 to a lever 6 connected to the capacityvarying means. The rod 3 has two sets of ports 13, 24 and two shoulders 10, 11, and encloses a valve 15 provided with ports 25 and flanges 22, 23. The valve is operated by a hand-lever 17, 18, and when moved down by the lever, it opens the ports 13 and connects the space 35 below the piston 2 to exhaust through the ports 25, 13, 26, and enables pressure-liquid from the pump &c. entering at the port 28 to move the piston 2 downwards and operate the lever 6. This movement of the piston restores the piston and valve to their original relative positions. If the pressure in the apparatus is insufficient, the piston 2 may be moved by operating the lever 17, 18 so as to push the valve 15 down on the shoulder 11. Specifications 19519/11 and 26678/12 are referred to.

Abstract: 124,509. Vickers, Ltd., Challenger, G. H., and Savage, H. A. Feb. 19, 1916. Fire between aircraft propeller blades, controlling and synchronizing.-Relates to guns mounted on aircraft and controlled by a cam driven by the propelling gear of the aircraft to enable the gun to fire safely between the blades of the propeller, for example as described in Specification 124,486. According to the invention, the time of action of the cam is controlled by the speed of the propeller by means unaffected by gravity and acceleration, in order to correct for the practically constant time lag which occurs between the action of the cam and the passage of the shot through the propeller. In the form shown, the cam A engages spiral feathers on its shaft a, which is driven from the propelling gear of the aircraft by a worm wheel a<1> in engagement with a straight feather on the shaft a; the angular position of the cam relatively to the shaft a and worm a<1> can thus be varied while the parts are running by sliding the shaft one way or the other. This is done proportionately to the. speed of the aircraft propeller by connecting the shaft a to a piston B controlled by a spring B<2> and subjected to fluid pressure from a gear pump driven by the propelling gear of the aircraft, a variable leak b<2> causing the displacement of the piston B to be proportional to the speed of the propeller.

Title: Roller Mills.
Inventor: MARCY FRANK EARL
IPC: B02C17/18
Filed: 1919-02-05
Abstract: 136,950. Marcy, F. E. Feb. 5, 1919. Ball and like mills.-In rod mills of the kind in which there is a constant flow of material through the barrel, the discharge end being left open for the discharge of the material and the insertion and withdrawal of the rods, the walls of the barrel are provided with means for preventing the rods from being discharged; this means may be supplemented by providing a conical flange or a disk or guard at the discharge end, and by inclining the axis of the barrel towards the feed-end. In the mill shown in Fig. 1, the barrel 1 is provided with a feed-trunnion 6, and the discharge end enters a casing 21, which may be provided with a hinged door D. The barrel is supported by rollers A and a bearing y, and may be horizontal or be inclined towards the feed-end, in which case a thrust bearing 9 of the following character is provided. The bearing, adjustable on a base 10 by a screw 14 and secured by bolts, supports a hemispherical bearing-member 16 carrying one end of a shaft 8 which is formed with a ball a entering a socket in the trunnion 6. The shaft is formed with a thrust collar 8<11> which abuts on a ball ring 18. For retaining the rods 4 in the barrel, the liners 2 are formed with lifting-ribs 3, the ribs preferably being disposed helically, and the barrel being rotated in a direction to cause the feedends of the ribs to precede the discharge ends. In the upward movement of the ribs, the rods are released by the discharge ends before being released by the feed-ends, and are thus deflected towards the feed-end of the barrel. The discharge end of the barrel is provided with a guard such as a disk 23 which deflects and returns towards the feed-end of the barrel any rods that escape from the lifting-ribs. The disk may be of circular, square, or other shape, and be arranged at right-angles or inclined to the axis of the barrel. The guard may be stationary or rotatable. As shown, the disk 23 is carried by the door D of the casing and is arranged within a flange 20 for building up the pulp-line x. The material is discharged through an annular opening o between the bevelled rim t on the disk and the bevelled edge m<1> of the flange 20 and a liner 20<1>. The inclination of the opening o prevents the rods from working through the opening. The disk may be provided with a stem 25 which is inserted in a bracket 24 on the door D, access to the barrel being obtained by opening the door. In the mill shown in Fig. 12, a guard-disk is dispensed with, a conical flange 39 being provided for retaining the rods 4 in the mill and building up the pulpline x.

Filed: 1925-02-02
Abstract: 254,353. Watt, R. A. W., Appleton, E. V., and Herd, J. F. Feb. 2, 1925. Cathode ray and optically-sensitite, relays.- The cathode ray from a discharge tube of the oscillograph type is controlled by the received signals alone or by the combined application of voltages derived in part from the desired signals and in part from a local oscillator so as to trace out a predetermined pattern. The discharge stream, or the resultant light-ray produced by its impact on a fluorescent screen, is then passed through a template interposed between one unit of the amplifying chain and an optically sensitive cell. In this way undesired signals, or atmospheric disturbances are prevented from impressing any permanent effect upon the detecting or recording apparatus. As shown in Fig. 4, amplified signal-voltages from a triode A' are applied across the plates Y, Y<1>' of a cathode-ray tube O, whilst other voltages derived from a local oscillator as described in Specification 235,254, [Class 37, Electricity, Measuring &c.], are applied across the plates X, X'.. If the two voltages are suitably chosen, the resultant effect of the electrostatic. forces applied across the x and y axis will cause the ionic beam to trace out a path of the form a, b, c, d, e, Fig. 1, or some similar path. A template s, cut out to the same pattern, is interposed between the tube O and a sensitive cell p in the input circuit of the subsequent amplifying unit A<2>, so that the desired signal frequencies are persistently applied to the cell p whilst other frequencies exert only a transient effect. Fig. 3 shows various shapes of templates having different selective properties. With a zero time period along the x, x<1> axis, a will pass all amplitudes exceeding the width of the bridge z, b is a high-pass filter, c a. low-pass filter, and d a band filter, the latter being particularly suitable for receiving telephony. Templates e and f when used with suitable time-base frequencies, are high and low pass filters respectively, and are also selective as regards frequency and wave-form; the selectivity of the template g as regards frequency and amplitude is governed by the width of the pierced slot, whilst the template h is suitable for shaped signals. The control pattern may be obtained by using lowfrequency derivatives of the incoming radiofrequency oscillations. Coupling means such as the condenser k may be provided between the receiving circuits and the time-base circuits in order to control their synchronization. According to the Provisional Specification two or more independent signals, whose frequencies as applied to the oscillograph are in an integral radio, may be received simultaneously by the provision of a suitably-shaped template.
