Title: Simulated directional gyro for aviation trainer
IPC: G09B9/24
Filed: 1944-05-26
Abstract: 580,986. Ground trainers. LINK AVIATION DEVICES, Inc. May 26, 1944, No. 10280. Convention date, July 28, 1943. [Class 4] A dummy direction indicator for use in a ground aviation trainer has non-gyroscopic means for causing its reading to change in response to turning movements of the body in which it is mounted and also means for causing its reading to change in simulation of a directional gyro. The support 14 of the trainer fuselage 10 is free to turn in a stationary housing 16. The wheel 36 of a turning motor 28 actuated by pedals in the fuselage rolls along a stationary belt 40 so as to turn the fuselage 10 to which the motor 28 is secured. A collar 48 fast with support 14 carries round with it a gear 54, -meshing with a fixed wheel 56 and driving through a flexible shaft 62 and gear wheels a bevel wheel 76 forming part of a dummy gyro 64. The bevel wheel 76 is fast with a central shaft 92 and drives through the sun-and-planet gear shown an inner clutch member 104 normally engaged by and so causing rotation of an outer clutch member 118, with which rotates an azimuth scale 136, the rotation being in the opposite direction to that in which the fuselage is being rotated and at the same rate, so that the scale is stationary and an index mark on the casing 78 moves over the azimuth scale as the fuselage is turned by the pilot. A further rotation corresponding to the precession of a directional gyro is also imparted to the azimuth scale by means of a worm-carrying shaft 164 driven by.a motor 156 through a cam-operated ratchet-gear 182, 192, a worm-wheel 200 driven by shaft 164 has an upstanding part 202 with internal gear-teeth meshing with the planet wheels 98, 100 and thus driving the inner clutch member 104 carrying round with it the outer clutch member 118 (normally engaged with member 104) which thus rotates the azimuth scale 136. Manuallyoperated means for varying the rate of simulated precessional movement are provided. Setting of the scale 136 by a magnetic compass can be effected by pushing inwardly a head 216 to bring a gear-wheel 226 into gear with a gearring on the under-side of outer clutch member 118, which is thus lifted up as shown to leave it free to be rotated to set the scale by turning the head 216. Specifications 370,128 and 481,375 are referred to.

Abstract: 376,357. Steam-actuated air com - pressors. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Thompson, B. H. ; Ardara, Pennsylvania, U.S.A.) April 10, 1931, No. 10627. Convention date, May 22, 1930. [Class 122 (ii).] Fluid-actuated valve year.-The air compressor is provided with cylinders 10, 15, the pistons of which are directly actuated by a pair of compound pistons 6, 11 respectively in cylinders 7, 12. The steam is distributed to the power pistons by a piston valve with differential actuating heads. The supply of actuating fluid is controlled by the main piston 6 and partly by an auxiliary valve actuated by the main valve through lost-motion mechanism. The control valve comprises a series of connected pistons 19 .. 22, a head-23 of greater diameter, and a head 24 intermediate in area between the areas of the pistons 22, 23. From. the valve boss 25 projects a stem 26 with a head 27. The boss 25 and head 27 actuate the auxiliary valve 28 arranged in a sleeve in a cover 35 secured to the valve chest. With the parts in the position shown in Fig. 1, steam passes from the inlet 36 to the top of the cylinder 7 and causes the piston 6 to descend. When the piston 6 passes the groove 42 steam passes to the chamber 44. The head 24 being greater than the head 19 which is also subject to steam pressure, the valve is moved to the left. When the valve boss 25 engages the valve 28, the head 19 closes the passage 41 and cuts off the supply to the top of the cylinder 7. Passage 46 is uncovered and steam flows from the upper side of piston 6 to valve chamber 45 and acts upon the opposed differential areas of piston heads 22, 23 and completes the movement of the main valve bv means of the intermediate pressure steam. In the valve position, Fig. 2, the lower end of cylinder 12 is connected to exhaust, the upper cylinder end is connected to the upper end of the cylinder 7, the lower end of which is supplied with high-pressure steam. The piston 6 is ascending and the piston 11 descending. Intermediate-pressure steam is passed from the upper end of cylinder 7 around the groove 54 in the valve 28 to the space 56. The valve is maintained to the left by the difference between high and intermediate steam pressure multiplied by the difference in area of the pistons 22, 24. When the piston 6 moving upwards uncovers groove 53, highpressure steam passes to chamber 56 and moves the main valve to the right. The top of cylinder 12 is put to exhaust, steam flows from the lower side of cylinder 7 to the lower side of cylinder 12, and high-pressure steam to the top of cylinder 7. Steam at intermediate pressure has access to chamber 56. The valve is maintained to the right by the difference between high and intermediate pressures acting on heads 19, 22 respectively. The valve movement to the right is cushioned by the head 24 overlapping a slot 60 in the bushing 32, and to' the left by the valve 28 covering a slot 62 connected to a chamber 63 to the left of the valve.

Abstract: 309,197. Kuchenmeister, H. J. April 7, 1928, [Convention date]. Cases with internal horns; tone-arms; tonearm joints; brakes, arrangement of.-In a cabinet gramophone wherein the horn extends around the motor with its mouth terminating towards the end of the cabinet housing the tone-arm, the tone-arm 3 is adapted to turn about a horizontal axis upon a hollow head 4 itself mounted to turn about a vertical axis provided on a vertical hollow column fixed in the cabinet and connected at its lower end to the horn inlet. To house the tone-arm after playing, it is rotated first about the vertical axis and then about the horizontal axis so as to lie in the space at the horn mouth and below the working platform. The Specification as open to inspection under Sect. 91 (3) (a) also describes a brake arranged so that it is automatically moved out of engagement with the turntable by the direct action of the tone-arm when the sound-box is placed on the record after being swung out of the recess. In conjunction with the brake, a detent is provided which holds the brake out of action during playing, and is tripped by means of the tone-arm at the end of the record whereby the brake is then automatically applied. On swinging the tone-arm upwards to the position shown in Fig. 1, and then rotating it to place the sound-box on the record, the bend 3a of he tone-arm engages a brake lever 11, 9, moving it against the action of a spring 10 so as to release the turntable. When this occurs, a detent 13 snaps into engagement with the arm 11, retaining the brake in the off position. An arm 15 frictionally and adjustably pivoted on the same axis as the detent 13 is adapted to be engaged by a projection on the tone-arm when the sound-box reaches the end of the record, whereupon the detent releases the brake, which stops the turntable. The winding spindle 19 is inclined upwardly into the horn mouth. This subject-matter does not appear in the Specification as accepted.

[Also in Division F4] A block of refractory material is sealed within a heat-shrunk wrapper of synthetic film. The block may be placed into its position of use while still wrapped, the heat of the installation burning the wrapper away when it is brought up to temperature. If the block is of a mouldable material, it may be moulded to the requisite shape while still wrapped, the moisture content thus being retained unchanged throughout. A sheet of combustible material may be included within the wrapper, or adhered to the outside thereof, in order to provide a gap between adjacent blocks when they are heated, to allow for thermal expansion of the refractory material. Alternatively a sheet of metal, which fuses with the refractory material on heating, may be used. The wrapper may be applied as two separate sheets, heat-sealed peripherally around the block and then heat-shrunk, or a single sheet may be folded longitudinally and heat-sealed transversely at one end to form a pocket into which the block is placed, the remaining two sides then being heat-sealed prior to shrinking. In a further form a series of blocks is wrapped in material supplied from two webs, which are transversely sealed together on both sides of each block, the end flaps then being sealed prior to shrinking. The wrapper may be applied as an open-ended tube not completely enclosing the block, this form being suitable if the material of the block is not liable to deterioration on contact with the atmosphere.
