Title: Improvements in arrangements for fixing thermal protection jackets in jet engine reheat chambers
Inventor: CAMBOULIVE ANDRE ALPHONSE MEDE
IPC: F02K1/80
Filed: 1966-06-10
Abstract: 1,118,257. Reheat combustion equipment. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. June 10, 1966 [June 11, 1965; March 22, 1966], No. 26047/66. Heading F1L. An arrangement for fixing a thermal protection lining 3 to the wall 2 of a jet propulsion engine reheat chamber 1 comprises, Fig. 1, a series of fixed attachment points 4 and at least one series of slidably mounted attachment points 5 distributed around the circumference of the chamber to permit the lining to expand longitudinally. The lining 3 has longitudinal corrugations and in one embodiment, Fig. 3, each fixed attachment point comprises a cup washer 6 whose skirt 6a fits over a correspondingly shaped portion of a corrugation peak of the lining and is secured thereto by a conically headed bolt 7 passing through the chamber wall 2 to receive a nut 8 and locking washer 9. The slidably mounted attachment points each comprise, Fig. 6, a slide 10 in the form of a cradle bolted to the wall 2 by two spaced bolts 11, 11' and in which slides longitudinally a necked cup washer 12 having a skirt 12a attached to the lining 3 by a rivet 13. In a modification, Figs. 8 to 10 (not shown), each fixed attachment point is formed by a cradle arrangement the same as that shown in Fig. 6 but in which the cup washer 12 is immobilized in the member 10 by means of two spaced wedges. Instead of upstream fixed and downstream sliding attachment points, as shown in Fig. 1, the two series may be reversed or the lining may be supported by fixed points at its middle and sliding points at its upstream and downstream ends.

Title: Improvements in or relating to machines for shaping articles to a predetermined external contour
Inventor: WILLSHER ROBERT VICTOR
IPC: B23C3/18
Filed: 1948-10-06
Abstract: 651,092. Grinding turbine blades &c. NAPIER & SON, Ltd., D. Oct. 6, 1948, No. 26054. [Class 60] [Also in Group XXII] A machine for shaping articles such as turbine blades to a predetermined contour comprises a cutting tool 11, Fig. 2, a workholder 13 which is supported on a pair of spaced cam tracks 24, 25, Figs. 1 and 2, through the agency of cam followers 22, traversing and guiding mechanism for causing traversing movement of the workholder relative to the cutter, and mechanism for simultaneously causing relative movement between the cam tracks and followers at a linear speed which is greater than that of the traversing movement. The workholder 13 is mounted on a transversely-movable bed 12 beneath the grinding wheel or milling cutter 13, the article 20 to be shaped being secured by clamps 19 on a cradle 18 which is supported on horizontal pivots 17, Fig. 3, carried by vertically-moveable slides 16; each slide is supported on an upright 14 and urged downwardly by a spring 16. Each follower 22 is in the form of a roller mounted on a spherical seating at the end of a non-rotating spindle 21 projecting from the adjacent side of the cradle 18. The cam tracks 24, 25 are longitudinally-slidable in guides 26 and are urged to the left in Fig. 1 by springs 29. A cross-member 30 connecting the guides 26 carries a pivot 31 on which are pivoted two levers 32, 33 carrying rollers 34-37 at their ends, the rollers 34, 36 engaging extensions 39, 40 on the workholder and the rollers 35, 37 extensions 41, 42 on the cam tracks 25, 25. As the bed 12 and workholder are moved to the left in Fig. 1 for cutting, the levers 32, 33 force the cam tracks to the right by twice the distance traversed by the workholder since the rollers 35, 37 are twice as .far from the pivot 31 as are the rollers 34, 36; the cam tracks are therefore three times as long as if the workholder alone were traversed, and much Hatter gradients are necessary on the cam tracks. To permit moving the work 20 out of contact with the cutter during the return movement, the cam followers 22 are retractable from the tracks by mounting each spindle 21 so that it is axially slidable and urged inwardly by a spring, being retained in its normal outer position by a spring- pressed locking pin which is forced to release position at the end of the cutting stroke by a stationary spring abutment 51. Towards the end of the return movement, pins 54 depending from the spindles engage stationary cams 53 for urging the rollers 22 to their normal outer positions. In a modification, the cutter is moved while the workholder is stationary, the movement of the cam tracks alone being responsible for controlling the position of the workholder during cutting.

Title: Balancing of aircraft control columns
Inventor: WATSON HENRY ROMAINE
IPC: B64C13/24
Filed: 1950-10-28
Abstract: 681,643. Controlling aircraft. ARMSTRONG WHITWORTH AIRCHAFT, Ltd., Sir W. G. :June 11, 1951. [Oct. 28, 1950] No. 26346/50. Class 4. An aircraft control column, such as is pivotally mounted near its lower end for fore-and-aft movement, has connections with at least two balance weights which are arranged so that their effects will be additive for balancing against change of attitude of the aircraft, and suhtractive for balancing against fore-and-aft movement of the column. The control column 11 is pivoted to the aircraft structure at 12 for fore- and-aft movement and is connected at a distance a above the pivot 12, to an elevator control rod 14 through the medium of a link 13. The rod 1 4 has spaced connections 20 for arms 18 and 19 which respectively carry weights 16 and 17 and are pivotally connected at points 21, distance b from pivots 20, to links 22 connected to the aircraft structure. The weight 16 is generally heavier than the weight 17 which is arranged in an unstable attitude and the arrangement is 'such that on movement of the control colunm, and a gear ratio of a/b, the balancing effect of the larger weight 16 will tend to resist movement of the column whilst the effect of weight I 7 will tend to assist such movement, but if the control rod 14 moves relative to the aircraft structure as the of a change of attitude of the aircraft, both weights will tend to oppose such movement. The embodiment described is only effective over a small range of movement of the control column and the weights are supported directly by the rod 14. Other embodiments are described which overcome these disadvantages and in one arrangement the weights are mounted in the aircraft structure by arms which carry toothed sectors engaging with a rack secured to the rod 14.

Title: Improved manufacture of hexamethylenetetramine
IPC: C07D487/18
Filed: 1925-10-23
Abstract: 252,609. Wade, H., (Karpen Bros., S.). Oct. 23, 1925. Hexamethylenetetramine.-Ammonia is introduced into an aqueous solution of hexamethylenetetramine, whereby the saturation point of the latter is lowered and it is precipitated in a pure form, the means of purification being incorporated in the process for the, production of hexamethylenetetramine from formaldehyde and ammonia. A dilute solution of hexamethylene. tetramine received from a condenser K is passed from a tank A through scrubbers B, where it is mixed with formaldehyde before being introduced into a cooled tank C. Here the mixture is saturated with ammonia gas supplied from a tank D containing liquid ammonia, most of the hexamethylenetetramine formed being precipitated by the excess of ammonia. The precipitate and remaining solution are passed to a filter and washer E, whence the precipitate is passed through a dryer F to a storage tank G. The solution is passed to a still H, from which ammonia passes through a condenser J back to the tank D, and the remaining solution either to the tank K, or to an evaporator M, from which crude hexamethylenetetramine is passed to a dryer N and storage tank O. Or a concentrated solution of the crude compound from the chamber M may be passed to a cooled tank C' and then be treated with ammonia gas from the tank D, the resulting precipitate being passed from a filter E<1> to a dryer F<1> and storage tank G<1>, and the solution to a still H<1>, whence the ammonia is returned through the condenser J to the tank D. If the reaction in the tanks C, C' is carried out under sufficient pressure, they need not be cooled.

Abstract: 359,640. Speed and revolution-direction indicators. CHADBURN'S (SHIP) TELEGRAPH CO., Ltd. and BAMFORD, A. C., Cyprus Road, Bootle, Lancashire. Sept. 8, 1930, No. 26712. [Class 106 (iii).] Relates to apparatus in which one pointer indicates revolutions per minute and another on the same dial indicates direction of movement, the motion being transmitted to the speed pointer by a unidirectional drive, and consists in employing speed indicating apparatus in which the pointer is operated by the armature of a magnet the spindle of which is driven through a unidirectional mechanism. The spindle 2 is driven from the part the speed of which is desired through a clutch 1 and drives through gearing a spindle 10 carrying a magnet 6. The armature 7 of the magnet which is moved against the influence of a spring (not shown) is carried by a separate spindle 11 in line with the spindle 10 and on which is the speed pointer 3. The gearing between spindles 2 and 10 comprises an oscillating frame 13 loose on the spindle 2 and carrying two toothed wheels 14 meshing with a toothed wheel 15 fast on the spindle 2. One of the wheels 14 is adapted to drive a pinion 16 on a spindle 17 driving the spindle 10 through bevel wheels 18, 19, while the other wheel 14 is adapted to drive the pinion 16 through the medium of a wheel carried by the frame 8 and in permanent mesh with the wheel 16. Thus when the shaft 2 is rotating in one direction one of the wheels 14 is effective and when the shaft is reversed the frame 13 is swung due to friction of the gearing so that the other wheel 14 is effective, the spindles 17 and 10 always rotating in the same direction. A pointer 4 on a spindle 22 driven through bevels 23 indicates direction of rotation and by counting the revolutions of this pointer and using a stop watch the speed may be checked.
