Title: Metal-glass resistance material
IPC: C03C17/02
Filed: 1964-02-12
Abstract: An ohmic resistance material comprises a metal-glass mixture of 84-50% by weight of glass and 16-50% by weight of inidium alloyed with at least one of the metals gold, palladium and silver.  The metal glass mixture is fired to a ceramic base (alumina, steatite, fasterite, zircon porcelains) and may be in the form of an arcuate or rectilinear track.  The resistance material is prepared by mixing very small glass particles with a solution of resinates of the required metal proportions, heating to 700 DEG  F. to remove volatiles and organic materials and to decompose the metal compound. The resulting material is ground to a fine powder and calcined at 850 DEG  F.  The resulting calcine is ground to a fine powder and results in a fine powder of glass particles, each coated with extremely small particles of metal. This powder is applied to the base material and fired to produce a continuous phase of solidified glass.  The glass may be made by dry mixing a batch of the raw materials, melting in a ceramic crucible to give a clear fluid glass, and pouring it into cold water.  The resulting shattered glass is dried and ground to a fine powder.

Title: Control systems for aircraft
Inventor: SUMMERLIN FREDERICK ARTHUR
IPC: G05D1/00
Filed: 1956-02-24
Abstract: 802,672. 'Controlling aircraft. SPERRY GYROSCOPE CO., Ltd. Feb. 15, 1957 [Feb. 24, 1956], No. 5815/56. Class 4. In an aircraft control system in which manual control is supplemented by automatic damping means applying to the control surface a damping movement commensurate with a damping signal which is a function of angular motion of the aircraft or a condition accompanying such motion, the damping signal is modified by airspeed responsive means so that the damping torque applied by the control surface for a given condition of angular motion is independent of air speed over a predetermined speed range. In the Figure, an angular velocity signal appropriate for example to an axis about which the aircraft has low stability, is derived by a rate gyro 1 as an A.C. signal of variable phase and magnitude and is converted to a D.C. signal of corresponding polarity and magnitude by the discriminator 2. This signal is fed to a " phase advance " unit 3 which has an output equal to the input plus a short term version of the input, to which is added the output of an integrator 4, which may be of the resistor-capacitor type shown or an integrator servo driving a potentiometer. The integrated signal is added to the output of unit 3 in the opposite sense. The combined signal is fed to a limiter unit 10 comprising opposed rectifiers 11, 12 each biased by a fixed voltage so that one or other rectifier will short circuit the combined signal according to its polarity if it exceeds in magnitude the fixed voltage. The limited combined signal is fed to a potentiometer 13, the wiper 16 of which is adjusted by a servo 15 controlled by an airspeed responsive unit 14. Normally, the signal on wiper 16 decreases as airspeed increases, but if, for example, the signal is required to increase with airspeed above a certain airspeed, this is done either by energizing and contouring potentiometer 13 appropriately, or by driving the wiper through a suitable cam. The output on wiper 16 is added to that on the wiper 19 of a potentiometer 18, controlled by a manual controller 17. The combined signal actuates a fluid pressure servo 26 through amplifiers 9 and 23 and a transducer 24, a feed back signal being provided by the wiper 21 of a potentiometer 20 controlled by the control surface 22. The servo 26 may be connected with the controller 17 to provide feel. The signal from wiper 19 may also be passed through the potentiometer 13. The damping signal may be derived from an accelerometer responsive to centrifugal force instead of the rate gyro 1, and may operate a control surface separate from that operated by the manual controller, or a servo tab on surface 22. Specifications 718,171 [Group XXXVI] and 802,673 are referred to.

Specified alkylating agents are (a) oxonium salts having a trialkyloxonium cation and an anion contain one atom of a polyvalent metal and one more halogen atom than the valency of the metal, e.g. FeCl4-, SbCl6-, BF4- or AlCl4-, and (b) alkyl sulphates.  Specified primary amines are ammonia, hydroxylamine, hydrazine and various organic mono- and polyamines; they may be dyes containing an amino group.

Abstract: 211,010. Moody, L. F. March 6, 1923. Axial-flow type; combined-flow type; blades, regulating; working-fluid supply. - In an hydraulic turbine having stator blades 3 for radial inflow and runner blades 4 of the axialflow or axial-radial flow type, the wall of the transition space 5 adjoining the tips of the runner blades forms part of a movable annular plunger 7, which is adjusted by hand or governor to shut off more or less of the blade ring 3 and restrict correspondingly the transition space 5. The plunger 7 may be actuated by fluid pressure admitted by a pipe 12 to the space below a piston 9 forming part of the plunger. In a modification, the space above the piston may also be connected to the source of fluid pressure. Under flood conditions, the plunger is moved to the full open position d, thereby increasing the clearance p at the blade tips so as to by-pass a portion of the flow and produce an ejector action in the discharge tube 2. The runner blades B, Fig. 2, are unshrouded and have a width w which is considerable at the base and is reduced towards the tip as shown at w<1>.

In the construction shown, the catch 12 is pivoted at the junction 8 of the arms 3, 6 and is connected by a pivoted telescopic rod 15, 16 containing a spring 14 to a point 17 on the link 6. Owing to the action of the spring 14 the catch 12 automatically snaps into engagement with a pin 13 on the link 2 during the erection of the supporting structure, and is released by sliding rearwardly the telescopic part 15, which is provided with a thumb-piece 19, against the action of the spring 14. A projection 21 on the lower side of the catch 12 co-operates with the underside of the link 6 to determine the position of the catch in its free condition and to hold the catch in a correct position for engaging the pin 13.

Abstract: 662,658. Drying granular materials VISSAC, G. A. March 10. 1949 '[March 19, 1948], No. 6570/49. Class 34(ii) Granular material such as coal is dried by passage over sloping screens in a plurality of stages, pulsating hot gases being passed downwardly through the material in the first stage and upwardly in a succeeding stage. A casing 10 contains shaking screens 16, 17, 18 alternately sloping in opposite directions and each having spaced parallel decks 20, 21 the openings of which are smaller than those of the deck above. The upper end of screen 16 is located below a hopper 11 with discharge opening 12 controlled by a feedgate 30 pivoted at 31 and having a counterbalance 32. Hot gases supplied to a hood 13 above screen 16 by a pipe 38 are directed downwardly on to the material and a pipe 40 connects the area below the screen to a pulsator 41. A hopper 35 having discharge pipes 36 removes water and fine material passing' through screen 16. Hot gases from a pipe 68 are directed by a baffle 69 upwardly through screw 17 and are removed by a pipe 70 connected to a pulsator 71. Hinged baffles 45, 55 direct the material from the upper decks of the screens to the screens below or out of the apparatus to shoots 46, 56, and shoots 63, 64 extending from the decks of screen 18 direct the dry material out of the apparatus, the very fine particles falling through the screens into a hopper 80 whence they are removed by a screw conveyer 81. Hot gases from a pipe 74 are directed downwardly through screen 18 by a baffle 75 and are removed by a pipe 76 connected to a pulsator 77 the pulsators 41, 71, 77 being driven by a common source of power at 45 degrees difference in phase. The gas supply to each screen is thus independent of other screens and the pulsating flow helps to prevent clogging of the screens.
