Abstract: 903,209. Control of motors; speed-responsive switches. BECKMAN INSTRUMENTS Inc. May 9, 1961 [Aug. 3, 1960], No. 16769/61. Classes 38 (3) and 38 (5). [Also in Group II] An overspeed safety device 24 for a centrifuge rotor 10 driven by an electric motor comprises a pin 28 that is carried by the rotor, normally held in an inoperative position, and has a part 36 which when the rotor speed exceeds a predetermined amount is designed to break under tensile stress due to centrifugal force to thereby release the pin and allow it to move radially outwards to actuate means to stop or decelerate the motor. The pin 28 is slidably mounted in a tubular housing 26 screwed into a bore 27 in the rotor and has a head 33 that abuts the end 34 of the housing to normally lock the pin in its retracted position. When the neck 36 fails under tensile stress at the maximum allowable rotor speed, the pin moves outwardly to the position indicated by 41 and breaks or bends a conductor pin 41, thus interrupting an electric circuit arranged to either stop or reduce the speed of the motor which drives the rotor through shaft 12.

Abstract: 595,131. Indicating fuel consumption. BENDIX AVIATION CORPORATION. Sept. 6, 1944, No. 17073. Convention date, Oct. 12, 1943. [Classes 106 (iii) and 106 (iv)] [Also in Group XXXVIII] A device for indicating the rate of fuel consumption of a vehicle, such as an aircraft, comprises a logarithmic scale and a pointer driven through electrical repeating systems by an air-speed responsive device and a fuel-flow responsive device; respectively. A capsule 13 is subjected to static and dynamic pressure so as to rock a gear sector 18 and therefore a. magnetic rotor 25 proportionally to the logarithm of airspeed. A tapped coil 22 surrounding the rotor is energized by a single phase or a pulsating direct current and is connected to a similar coil 26 surrounding a similar rotor 27 in a repeater 4. The rotor 27 actuates a pointer 9. The vane 40 of a fuel flowmeter is rocked by the flow of fuel against the action of a spring 45 (Fig. 1 and Fig. 3, not shown), a magnet inside the flowmeter causing a magnet outside the fluid-tight casing to rock proportionally to the logarithm of the fuel flow. A rotor 53 moves with the second magnet. The coils 55, 56, 57 of a stator are in circuit with the coils 58, 59, 60 of the stator of a receiver 6, the coils being energized from a common source. The rotor 64 accordingly follows the rotor 53 to rotate a dial 8 proportionally to the logarithm of fuel flow. The pointer 9 therefore indicates fuel consumption in miles per gallon on the logarithmic scale of the dial 8. Specification 565,277, [Group XXXVIII], is referred to.

Title: Relief valve mechanism applicable to pressurized enclosures
IPC: B64D13/04
Filed: 1951-07-23
Abstract: 696,333. Fluid-pressure servomotors; fluidactuated valves. GARRETT CORPORATION. July 23, 1951 [Aug. 3, 1950], No. 17380/51. Class 135 A pressurized aircraft cabin outflow-valve is arranged to open in response to excessive differential between cabin and atmospheric pressures due, e.g., to malfunctioning of the usual cabin pressure regulator to which the present valve is additional, or in response to operation of a manual control, or in the event of atmospheric pressure exceeding cabin pressure. The movable valve member 60, 63 has an annular knife edge 62 coacting with a seat 21 and is loaded by a light spring 120. Attached to the valve member are an annular diaphragm 80 which is also clamped at its periphery between a cage 16 within the cabin and a cover 77, and a diaphragm 50 which is attached at its centre to a sleeve 38 fixed within a pedestal 30 mounted on a spider 33 in the outlet opening and normally lies against a fixed abutment 41 carried by the pedestal. In the event of atmospheric pressure exceeding cabin pressure, the diaphragm 50 is urged by atmospheric pressure away from the abutment 41 into contact with the part 63 of the main valve member, thereby opening the latter. In a modification, the sleeve 38 is slidable in the pedestal. Cabin pressure is admitted to a chamber 81 through a restricted opening 82, and also to a chamber 70 through openings 64. If cabin pressure exceeds a predetermined differential over atmospheric pressure, a valve 96 consisting of a spring tongue mounted in a chamber 88 connected to atmosphere by a pipe 83 opens against a spring 99 and vents the chamber 81, allowing cabin pressure in the chamber 70 to open the main outflow valve. The main valve may also be caused to open by the opening of a manually-actuated valve 117 in a pipe 105 which leads to the atmosphere. A valve 96a similar to the valve 96 but without spring- loading is interposed between the chamber 81 and the pipe 105. Instead of being operated under manual control through the valve 117, the main valve may be actuated mechanically or electrically.

Abstract: 1292519 Granulated denture cleaning compositions COLGATE PALMOLIVE CO 13 April 1970 [14 April 1969] 17452/70 Heading C5D A powder composition for cleaning dentures is converted to granular form by (a) compressing and de-aerating it, (b) extruding it as a sheet, (c) breaking the sheet into granules and (d) separating granules of a particular size range from under- and over-sized material. In a particular embodiment, Fig. 1, the composition ingredients are introduced at hopper 12, mixed whilst being transported by screws 44 and 46 and conduit 20 to hopper 22 and transported by screw 24 to screw 26 which compresses and de-aerates them before expelling them through constructed outlet 52. The expelled material is rolled into a sheet which is broken up by rotating blades mounted on axle 30. Grid 32 retains the material in contact with the blades until it is fine enough to pass through to sorter 36, which screens out under- and oversized material for recycling via conduit 38 and discharges granules of the desired size at 42. In a second embodiment (Fig. 5, not shown), sheet extruded from the rollers is first broken into chips and flakes by an upper set of rotating blades (86) and then falls to a lower set (88) where it is granulated.
