Title: Apparatus for mixing two fluids
IPC: B01F23/10
Filed: 1971-01-19
Abstract: 1292763 Fluid logic and switching circuits UNITED AIRCRAFT CORP 19 Jan 1971 [4 Feb 1970j 2530/71 Heading F1P [Also in Divisions B1 and G3]  An apparatus for homogenously mixing air and oxygen within a chamber 26 such that the resultant mixture is suitable for use in a respirator, comprises air and oxygen sources 16, 30 which are connectible to the mixing chamber by amplifier valves 14,12, and a control amplifier 44 which sequentially operates the two amplifier valves 12,14, the control amplifier having associated therewith two timing mechanisms 46,48, and being supplied with air from source 16 via line 50. Assuming the state of the control amplifier 44 to be such that air supplied to power input 48a passes to output 86, then this output is fed to line 88 and is thereafter split. Part of the output enters amplifier valve 14 and so causes air entering port 18 to be deflected from amplifier output 22 to output 24. Accordingly, the air source is connected to the mixing chamber 26. The other part of the control amplifier output enters line 90 wherefrom it passes into two chambers 70, 80 of the timing mechanism 46, the chamber 80 filling less rapidly than chamber 70 by virtue of the adjustable throttle 94. Upon chamber 70 filling to the limit of deflection of its diaphragm 66, chamber 80 continues to expand until its diaphragm 64 engages a port 100 which is connected to a control port 104 of control amplifier 44. Consequent to such engagement occurring, the output from amplifier 44 is switched to port 106 and so amplifier valve 12 is placed in a state where it supplies oxygen to the mixing chamber and timing mechanism 48 is rendered operative. After a time lag as determined by throttle 94', valve 14 and mechanism 46 are again rendered operative. Two modifications of the circuit and of the timing mechanisms are depicted in Figs.2 & 3 (not shown).

Title: Improvements in and relating to apparatus for controlling the line of aim of a sighting device
IPC: F41G5/00
Filed: 1943-02-18
Abstract: 631,517. Sighting apparatus. SPERRY GYROSCOPE CO., Inc. Feb. 18, 1943, No. 2750. Convention date, July 23, 1941. [Class 92 (ii)] [Also in Groups XXXVII and XXXVIII] Apparatus for controlling the line of aim of a sighting device to follow a target comprises a control unit 9 connected to the sighting device 1 to move in fixed relationship therewith, the control unit having mounted for angular movement thereon a manual control member 11 for controlling sight-driving mechanism and so arranged that it can be manipulated by part of the hand of an operator, with another part of the hand grasping or resting on a reference knob 50 on the control unit. The handle 11 has limited angular movement about two perpendicular axes, such movement producing signals corresponding in magnitude and extent to the angular displacement of the handle 11, and controlling two servo-motors 17, 17<SP>1</SP> for turning the sighting device 1 about axes parallel to those about which the control member 9 is moved, each servo-motor being controlled through the intermediary of control apparatus (see Group XXXVIII), such that for any steady value of the control signal the relevant servomotor operates to turn the sighting device at a speed and in a sense corresponding to the magnitude and sense of the angular displacement of the control handle 11. The sighting device 1 is movable in elevation about a horizontal axis 2 at the upper end of a vertical shaft 3 about which it turns in azimuth, and the control member 9 is secured at the end of a horizontal shaft 5 which is rotatable in a yoke 4 on the shaft 3. A slight vertical movement of the handle 11 generates a signal which is amplified and energizes one field of the two-phase servo-motor 17 in the requisite sense and thereby drives pinions 15, 13 to rotate the shaft 5 and, by means of links 8, 7, the sighting device 1 is elevated or depressed according to whether handle 11 is elevated or depressed. Similarly a slight movement in azimuth of the handle 11 produces operation of servo-motor 171 driving a gear-train which rotates the vertical shaft 3 and transmits movement in azimuth to the sighting device. The handle 11 is mounted on the end of a rigid rod 53 secured axially to a spherically faced button on a member 57 carried by a resilient portion 59 of reduced crosssection, whereby handle 11 can be given a vertical, lateral, or compound movement. Coarse and fine selsyn transmitters 31, 33 which may be connected to control the elevation of a distant gun are operated by a shaft 23 controlled through a mechanical differential 21 whereby the shaft 23 lags or leads the shaft 5 by an angle corresponding to any correction or prediction signals applied to a prediction motor 27 which drives a shaft 25 coupled to the differential. Movements in azimuth are similarly modified by a prediction motor 27<SP>1</SP> associated with a differential 21<SP>1</SP> on shaft 231. The prediction correction system, which is controlled electrically, is described in Specification 631,540.
