Title: Improvements in and relating to angular rate sensors
IPC: G01P3/36
Filed: 1966-03-22
Abstract: 1,116,416. Lasers. HONEYWELL Inc. 22 March, 1966 [2 April, 1965], No. 12668/66. Heading H1C. To prevent locking in to a common frequency of the two light beams passed in opposite directions around a ring laser angular rate sensor when low rotational rates are sensed, the two beams are biased by electrical or mechanical oscillations which cause periodic variations of their respective frequencies. As shown in Fig. 1, light beams 18, 26 emitted by a laser active' medium 10 pass along a closed path formed by reflectors 12, 14, 16, an output being obtained through reflector 12 which is partially lighttransmitting. The two light beams are combined by a reflector 20 and partially-transmitting reflector 22, and together produce a moving fringe pattern at a detector array 24 when the ring laser is rotated. The direction and rate of movement of the fringe pattern detected are determined respectively by the direction of movement of the ring laser and its rotational rate about an axis 28. The passage of the fringe bars is recorded by a counter 45 which is connected through a comparator 52 to an output counter 54, the rate of count being determined by rate monitors 60, 66. Monitor 66 improves the linearity of the system by controlling the power supplied to the active medium from a power source 68 and potentiometer 70. Monitor 60 closes a switch 62 when the rotational rate is low and so connects a power source 64 to an A.C. bias source 37, the A.C. bias being applied to a coil 43 which establishes a magnetic field in a Faraday medium 35. The medium, in association with quarter-wave plates 31, 33, produces an effective path length difference for the two oppositely-directed beams when energized and a resultant frequency difference which is sufficient to avoid locking in. To prevent an accumulated error on the counter 45, the bias source is reversed periodically so that the error signal is cancelled. Because of the modulation introduced by the sine wave bias which gives an additional count, a compensatory count in a counter 50 driven by the bias source is applied to the comparator 52. A mechanical bias is used in Fig. 2, in which the ring laser system is mounted for mechanical oscillation on a base 102 by leaf springs 90, 92, 94, reciprocation being produced by an electromagnet 122 which is driven by an oscillator 120. The two output beams passed by a partially-transmitting reflector 110 are combined by a prism 112 fixed to the base, this prism by changing the path length of the beam 106 as the ring laser reciprocates providing automatic compensation for the error due to frequency shift, Fig. 3 (not shown).

Title: Improvements in ferrochromium recovery
IPC: C22B34/32
Filed: 1953-05-11
Abstract: Ferro-chromium of controlled carbon content is produced by smelting a charge comprising chromite ore in a three-phase submerged are electric furnace in the presence of an amount of carbon sufficient to reduce all the iron of the ore and a substantial amount not exceeding 80 per cent of the chromium, thus forming molten metal and slag, introducing the molten product into an arc electrode furnace, placing on the layer of the molten slag solid reducing agent and fluxing material and maintaining the slag layer by combined arc resistance and slag resistance at a temperature sufficiently high to effect reduction to the metallic state of the chromium contained in the slag as oxide.  The ferro-chromium is then separated from the residual slag.  The reducing agent used in the second part of the process may be a solid carbonaceous agent or it may be a non-carbonaceous agent such as high- or low-carbon ferro-chrome-silicon in which case basic fluxing material may be used to give a slag having a base: acid molecular ratio in the range 1,7-2,0 base: 1,0 acid. With a carbonaceous reducing agent, basic fluxing material containing calcium oxide is used in sufficient amount to give a slag in which the base: acid molecular ratio is higher than 1,5 : 1,0.  In operation of the second furnace the arcing tips should be sufficiently close to the upper surface of the bath to minimise dissipation of the heat, for example they should be situated to provide arcs not greater in length than 1/2 inch and with a slag depth of at least 3 inches the position of the arcing tips may vary from 1/2 inch above to 2 inches below the slag surface.  Examples of the products have compositions Cr 69 per cent, Fe 25,5 per cent, C 4,8 per cent, Si 0,5 per cent, Cr 71,5 per cent, Fe 26,0 per cent, Si 1,0 per cent, C 1,5 per cent and Cr. 71,6 per cent, Fe 26,2 per cent, Si 1,57 per cent, C 0,56 per cent.

Filed: 1955-05-06
Abstract: <PICT:0775232/III/1> Apparatus for simultaneously spraying two materials such as paint, disposed in a container 7, and a hardening agent, disposed in a container 8, comprises a positive displacement pumping device having two separate pumping chambers 13, 19 containing pistons 16, 17 respectively joined by a shank 36.  Under the action of compressed air introduced into the top of the container 7, paint is forced through conduit 12 to pump chamber 13.  As the differential piston moves upwardly hardening agent from container 8 is sucked through a conduit 20 into pump chamber 19. Compressed air introduced at 33 passes through a valve chamber 42 and conduit 31 to close a valve 22 in the conduit 12, through conduit 34 to close a valve 27 in conduit 20 and through a conduit 35 to act on the top of the piston 16.  A spray gun 1 has a compressed air supply 4, a connection with the chamber 19 through a conduit 3, and a connection with chamber 13 through a conduit 2.  The spray gun has a trigger 5 which controls material and air valves in the gun.  When the trigger is pressed these valves are opened and material is delivered to the gun as the pistons 16, 17 descend under the action of the compressed air above piston 16. Valve chamber 42 is automatically vented to atmosphere when the gun 1 is hung on a hook 37.  In a modification, an arrangement for varying the proportions of feeding the materials comprises an adjustably pivoted arm 56, Fig. 2, one end of which is attached to a piston 17 working in a fixed cylinder 19 and the other end of which is attached to a cylinder 14 slidably mounted on a piston 16.  Paint is fed to the space above the piston 16 through a bore 55 in the piston rod 52.  The pivot point 57 may be adjusted within a slot 60 in the arm 56 for adjusting the proportions of feeding materials.
