Filed: 1916-10-16
Abstract: 125,660. Gray, J., and Gray, J. G. Oct. 16, 1916. Gyroscopic apparatus.-A gyroscopic compass is mounted on a framework forming part of a gyroscopic pendulum of the type described in Specification 14032/15 so as to protect it from the effects of rolling and pitching of the ship. As shown in Figs. 1 and 2, the compass comprises a gyroscope in a casing 1 stably mounted on bearings 2 on a frame 3 carried by bearings 4 on a frame 5, the frame 5 being stably or unstably carried by gimbals in a frame 13 which is mounted in bearings 14 on a frame 15 carried by springs 19 from a gimbal ring 20 mounted in the binnacle. The frame 3 carries a card 6, and the oscillation of the gyroscope about the meridian is damped by means of a dash-pot housed in a casing 1<1> secured to the casing 1, or in the manner described in Specification 17725/15. The dash-pot comprises two vessels 21. Fig. 3, connected by capillary tubes 22. and the vessels are completely filled with mercury 23 and oil or other viscous fluid 24. The dash-pot is mounted so that the tubes 22 are parallel to the axis of the gyroscope. The frame 5 constitutes part of the gyroscopic pendulum and has a casing 7 containing a gyroscope rigidly connected to it. The erector 9 may be driven through gearing in a case 8 by the gyroscope so as to rotate slowly in the same direction as the gyroscope, or it may be driven by friction or a wind-drive from the gyroscope, or by a separate motor. The erector may comprise an annular chamber divided by radial portions into two compartments, each containing a steel ball or a quantity of mercury; or, as shown in Fig. 5, it may comprise a chamber 9 having three hollows 31, 32, 33 of the shape indicated and each containing a quantity of mercury. The action of the erector and also other forms of erector are described in Specification 14032/15. The frame 13 is caused to follow the movements of the compass gyroscope by means of a motor 18 carried by the frame 15 and gearing 16, 17. the current to the motor being controlled by a two-way commutator. In a modified construction permitting the substitution of a wide binnacle for a long one, the frame 5 is mounted in a rectangular gimbal frame which also carries the gyroscope casing 7, and the erector and a motor for driving it, one on each side of the frame 5. The axes on which the frame 5, the gyroscope casing, and the erector &c. are mounted in the gimbal frame are parallel and are connected by means of cranks and a connecting-rod so as to move together.

Title: A means for controlling the speed of rotation of a gas compressor used in connection with or forming part of an internal combustion engine
IPC: F02D23/00
Filed: 1941-11-25
Abstract: 561,932. Fluid-pressure servomotor control systems. RAMSAY, D. Nov. 25, 1941, No. 15149. [Class 135] A servomotor control system for an internalcombustion engine supercharger comprises a boost control unit subject to induction pipe pressure arranged to control a pair of power devices, one of which controls the speed of the supercharger while the other actuates second control, such as a throttle valve. In the form shown in the Figure, a first stage compressor 3 is driven by an exhaust gas turbine 4 under the control of a valve 9, while a second stage compressor 10 is driven by the engine 5 and controlled by the throttle 14 for the carburetter 13. The valve 9 is connected by a linkage 31 with a double-acting piston 30 loaded by a spring 32, while the throttle valve 14 is coupled by a linkage 29 with an unloaded double-acting piston 28. Pressure fluid from a conduit 20 is simultaneously admitted or exhausted to and from the cylinders 23, 24 housing the pistons 28, 30 under the control of a control valve 18 actuated by a capsule 16 subject to the pressure in the engine induction pipe. The anchorage of the capsule is adjusted by a cam 17 actuated by a pilot's control 15. As the aeroplane climbs the piston 28 is gradually moved to the right so opening the throttle 14, when this piston has reached its extreme position the piston 30 is moved to the right to move the valve 9 towards its closed position and so bring the first stage unit into operation. To maintain the speed of the gas turbine within safe limits, temperature sensitive elements arranged in the inlet and outlet conduits of the first stage compressor are connected to members 35 adapted to actuate a control valve 36. As the speed rises the temperature difference increases and moves the valve 36 to energize a power piston which acts through the linkage 31 to move the valve 9 towards its open position. Specification 538,729 is referred to.

Abstract: 945,438. Discharge tubes. BECKMAN INSTRUMENTS Inc. April 28, 1961 [June 27, 1960], No. 15388/61. Heading H1D. [Also in Division G1] In an arrangement for detecting the presence of ionizable substances in a gas, such as the outflow from a chromatograph column, the gas is mixed with a second gas stream during its passage into an ionization chamber electrons which have previously been introduced into the second gas stream acquiring a considerably higher energy level under the influence of the electric field in the chamber, and in consequence effecting ionization of the components of the sample stream. The gas to be tested is admitted to the ionization chamber 24 by a pipe 37, Fig. 2, and the second gas (argon) is fed into the electron generator by a pipe 36. An ultraviolet lamp 25 acting on the metallic inner surface of tube 23, which may be copper, produces photo electrons which diffuse into the ionization chamber 24 with the second gas stream. The second gas, which may be argon, helium, neon, krypton, or Xenon, should have a high ionizing potential so as not itself to become ionized by the high energy electrons. Alternative electron generator metal linings are referred to including metal oxides, and metals like potassium and caesium of low work function responsive to visible light. The use of X-rays is also referred to. The projection of rays through the walls of a glass chamber and the use of a mercury arc lamp, hydrogen lamp, zenon lamp, or a heated filament are also described. Anode 33 is energized from a source 31 and the current after amplification in an amplifier 32 is recorded by a recorder 19. A modified arrangement, Fig. 3, includes an inwardly directed ridge 40 at the junction between the two zones and a baffle plate 41 on the inlet line of the gas under test. Numerous physical arrangements of the chambers including " in line," " L," " T " and concentric arrangements are described with reference to Figs. 4-9 and 11 (not shown), and an arrangement wherein the ionization chamber is included in a bore within a solid block of copper which latter forms the chamber for the electron generator is described with reference to Fig. 10 (not shown). The lamp in this latter arrangement projects substantially radially into the bore.
