Abstract: 398,493. Firegrates. BENNIS, A. W., Bennis Works, Highfield Road, Little Hulton, near Bolton. Feb. 5, 1932, No. 3424. [Class 51 (i).] Air supply, regulating. -In a forced-draught furnace in which the firebars are supported on longitudinally reciprocating troughs, each trough is divided by transverse partitions A<3> into compartments, vena-contracta nozzles supplying each compartment with air from a single chamber E, or from a number of chambers, in which air is maintained under pressure. The nozzles D are controlled by dampers D<1>, which may be actuated separately or together, for instance by being connected to levers operated by a drum with cam projections and laterally movable to operate different sets of dampers. The chamber E may be divided by longitudinal or transverse partitions, or both. Each nozzle may be fed from a single compartment. The nozzles D may as shown be fixed to the platform B which supports the trough A, or may be attached to and move with the troughs A, openings to enable this being provided in the platform B. The troughs may have side openings to supply air to the spaces between themselves. Openings A<2>, B<2> in the troughs and platform respectively are so disposed as to allow ash to fall through intermittently into hoppers F, provided with valves F<1>. The Provisional Specification describes a similar furnace in which the troughs are not subdivided. Such troughs may be fed by additional nozzles from an air chamber in front of the grate. It describes also an internally fired boiler, such as a Lancashire or Scotch marine type, in which an air-supply chamber is disposed at the front of the grate. Its lower wall is extended so as to form a platform on which the troughs rest. Vena-contracta nozzles are formed at the front of each trough. Air also passes from the chamber between the troughs. The base of each trough is open except for transverse bars, which during the motion of the bar expose openings in the supporting platform to discharge ash. Lateral extensions on the sides of the troughs may act similarly with respect to openings allowing the discharge of ash between the troughs. Specification 353,609 is referred to in the Provisional Specification.

Filed: 1947-02-05
Abstract: 636,545. Gyroscopic apparatus. BENDIX AVIATION CORPORATION. Feb. 5, 1947, No. 3428. Convention date, Feb. 11, 1946. [Class 97 (iii)] A gyrovertical having an erecting mechanism is provided with a nutation damping device comprising a mass free to move within limits with respect to an axis coaxial with the normally vertical axis of rotation of the gyro rotor. As shown in Fig. 1, a cup-shaped member 20, integral with the rotor-casing 11 and coaxial with the rotor shaft 15 has formed in its bottom wall 21 a conical depression 22 in which rests a steel ball 23 of slightly less diameter than the diameter of the cup 20. The cup is almost completely filled with a damping fluid 24 and covered with a gasket 25 and cover 26. Oscillation of the gyro-spin axis through angles less than 15 degrees causes the ball to oscillate in an opposite direction within the confines of the conical depression 22, thus damping the oscillation of the spin axis. During oscillations greater than 15 degrees the ball rides out of the depression 22 to abut the wall of the cup so as to assist the action of the gyro-erecting mechanism.

Abstract: 1299822 Gyroscopic apparatus SINGER CO 1 Feb 1971 3586/71 Heading G1C To determine the drift coefficients of vertical and azimuth gyros 10, 10a of a navigation system for an airborne or space vehicle, wherein each gyro has two input axes and an outer casing 12  rotatable about an axis parallel to or coincident with its spin axis SA, and the gyros being positioned with their spin axes at an angle to each other, a precession torque is applied to the gyros to maintain their spin axes in a predetermined spatial position, and the casing 12 is rotated to predetermined angular positions, the drift coefficients about the various reference axes being computed from the precession torques for the different gyro casing angles. In Fig.2, the gyros 10, 10a are mounted on a platform 80 with their spin axes at right angles to one another. The platform 80 also carries accelerometers 82 and is supported by a vertical shaft 86 and gimbal rings 88, 90 provided with synchros 92, torque motors 94, and a resolver 96. Measurements are taken with the vertical gyro casing in three different angular positions spaced 90 degrees apart Figs.4-6 (not shown), the azimuth gyro casing remaining fixed. Finally the azimuth gyro casing is rotated through a right angle Fig. 7 (not shown). The drift coefficients are derived from the torque precession rates applied by the gyro torquers 30, said rates being the appropriate torque scale factor multiplied by the average value over 20 to 100 seconds of the torquer current, the values of which may be computor stored. Each gyro comprises a cup-shaped rotor 14 connected by a necked flexure member 24 to the shaft 18 of an electric motor 16. A permanent magnet 26 mounted on the shaft 18 balances the spring torque applied by the flexure member 24. Two pairs each of torquers 30 and pick-offs 32 are provided for the rotor. The motor 16 and casing 12 of the gyro are mounted on a turntable 40 which can be rotated in 90 degree steps by a motor 50 which is constantly energized. Rods 58, 62 projecting at 90 degree intervals round the turntable 40 periphery are engageable with a flexible stop arm 66 on the base 44, the arm being momentarily pulled down by a solenoid 68 to release the turntable for a 90 degree step.

Abstract: 801,193. Explosive compositions containing aluminium. MAGNASCA, Ltd. Feb. 1, 1957 [Feb. 9, 1956], No. 3641/57. Class 9(2) An explosive mixture comprises a main explosive, aluminium in the grit state and at least one supplementary explosive of higher shattering power than the main explosive, the particles of the said supplementary explosive being coated with finely divided aluminium. In preparing the composition the supplementary explosive is treated with a solvent to make the surface of the particles sticky and then treating with finely divided aluminium and drying. Suitable solvents are acetone and glycol, and it is preferred to saturate the solvent with the explosive to be treated to 80 per cent saturation. The main explosive and the grit aluminium may be mixed in the presence of a binder e.g. collodion. The two mixtures so obtained may then be mixed and granulated. In an example trinitrotoluol, grit aluminium and barium nitrate are mixed with collodion as a binder and then mixed with hexogen coated with fine alumnium scales. In other examples the explosives used are (i) ammonium nitrate and tetranitropentaerythrite and (ii) nitroguanidine and nitromannite.
