Title: An improved instrument for use in the practice of iridiagnosis
IPC: A61B3/12
Filed: 1938-04-06
Abstract: 502,217. Eye-examining apparatus. FLOWER, C. H. C. April 6, 1938, No. 10499. [Class 97 (i)] An instrument for iridiagnosis, i.e. for determining the physical condition of the body by examination of the irises of the eyes, comprises means for illuminating the iris and obtaining a magnified image for observation, and a diagnostic chart within the observer's field of view to be observed simultaneously with the image of the iris. The casing 1 has at one side an aperture 2 to which the eye to be examined is applied, and at the opposite side an eyepiece tube 3 containing a lens 4, by which, in conjunction with an adjustable lens 5, a magnified image of the iris is produced and focused. The chart 13 is arranged in front of the lens 5 and is pivoted so that it can be swung into position. Preferably separate charts are provided one for the right eye and one for the left, each chart having an aperture 14 through which the iris is viewed, and a surrounding diagnostic diagram 15. The iris is illuminated by light from a source 28 passing through a lens 33 producing a convergent beam which is reflected by an adjustable mirror 35 on to the eye. Part of the light from the source 28 is reflected by mirrors 30, 32 to illuminate -the chart 13.

Title: Aircraft fuel supply systems
Inventor: BELL ROBERT HENRY
IPC: B64D37/16
Filed: 1959-03-26
Abstract: 896,184. Fluid-pressure servomotor-control systems. LUCAS (INDUSTRIES) Ltd., JOSEPH, and ENGLISH ELECTRIC CO. Ltd. March 16, 1960 [March 26, 1959], No. 10510/59. Class 135.  A fuel supply system for aircraft of the kind having a pair of engines and a pair of fuel tanks 1, 2 mounted within the wings, each fuel tank incorporating a boost pump 3, 4 for supplying fuel to an engine-driven fuel pump 9, 10 associated with each engine respectively, comprises a pair of fluid-actuated motors 5, 6 for driving the boost pumps 3, 4, respectively, a pair of variable delivery pumps 13, 14 driven by the pair of engines for supplying motive fluid in the form of fuel to the pair of motors, and means for maintaining the output of the variable delivery pumps at appropriately half their maximum output whilst both pumps are in action and for increasing the output of one of the pumps automatically in the event of the other pump failing to function. The variable delivery pumps 13, 14, as shown, supply the motive fluid at half their maximum output to the motors 5, 6 via passages 18, 19 and a solenoid-operated valve 16 provided in a valve housing 15. Also located in the housing 15 are two piston valves 27, 28 which each serve to control the flow of fuel from the upstream side of the pumps 9, 10 respectively to one side of servo-pistons 25, 26 adapted to vary the output of the variable delivery pumps 13, 14, respectively, such as by adjusting the position of a squash-plate; the other sides of servo pistons 25, 26 are each in communication with the output sides of the pumps 13, 14. If, during operation, the pump 13 for example fails, the pressure in the passage 18, which has been acting on the piston 22 of the valve 28 in order to maintain it in the position shown, fails and, thereby causes the pressure in the passage 19 acting on the other side of the piston 22 to move the latter into a recess 18a and thus permit the flow of fuel from the passage 19 into the passage 18. At the same time the valve 28 is moved to prevent the flow of fuel to one side of the servo-piston 26, thus allowing the output pressure from the pump 14 to leak through a restricted orifice 30 in order to cause a pressure balance on each side of the piston; the piston 26 then moves under the action of a spring to effect the adjustment of a squash plate. If one engine begins to use more fuel than the other then the position of the valves 7, 8 may be reversed and also the valve 16 simultaneously moved to its alternative position.

Title: Process for concentrating metals
IPC: B03D1/00
Filed: 1931-04-15
Abstract: Metallic particles are separated from gangue by flowing a suspension of the metal and gangue in a hydrocarbon oil over a concentrating table.  Preferably the table has longitudinal riffles between which the metallic particles settle and are carried to a discharge trough at one end of the table, the gangue in suspension being deflected by cross currents to a discharge trough at one side of the table.  The oil is then separated from both the concentrates and the gangue by sedimentation or distillation and is re-used to concentrate a further quantity of the mixed metal and gangue.  Any metal particles which have been retained in suspension with the gangue are recovered by subjecting the gangue, preferably after removal of the oil, to a magnetic separation.  The material to be treated is preferably classified by size before concentration and the process is particularly applicable to the concentration of iron particles from a mixture formed by heating iron oxide ore with pulverized coal, coke, or other carbonaceous material.  The mixture so obtained is preferably at once saturated with oil to prevent oxidation of the iron particles and then diluted by further addition of oil before concentration.
