Title: Improvements in or relating to methods of manufacturing articles from thermosetting materials
Inventor: REES JOHN
IPC: B32B27/00
Filed: 1952-03-12
Abstract: 722,612. Compound sheet materials. BRISTOL AEROPLANE CO., Ltd. March 4, 1953 [March 12, 1952], No. 6466/52. Class 140. [Also in Groups V and XXVIII] A method of making an article from fibrous material impregnated with uncured thermosetting resin comprises (a) applying the material to a former, (b) coating the exposed face of the material with an elastic-skin-forming substance to form an air-impervious elastic skin thereon, and (c) subjecting the skin-coated material to heat and pressure to force the material against the former and cure the resin. The exposed edges of the material also may be coated wth the substance. The substance may be rubber latex or a solution of natural or synthetic rubber. Fig. 1 shows a plain sheet-metal tubular former 10 to the interior of which are applied three layers 11, 12, 13 of asbestos sheet impregnated with uncured thermo-setting resin. The layers 11, 13 have helical butt joints 15, 16 of opposite hand, and the layer 12 has a longitudinal butt joint 14. The innermost layer 13 and the edges of all the layers are coated by brushing with a layer 18 of liquid paraffin wax, which is allowed to harden; this wax acts as a parting layer. Then a layer 19 of rubber latex in liquid or semi-liquid state is brushed on to the wax and allowed to coagulate to form an elastic skin 0.01 inch thick. The assemblage is then placed in an autoclave and subjected to a pressure of 100 lbs. p.s.i. and a temperature of 140‹ C. In a modified method the former 10 is provided with fluid-tight end closures, and the latex is poured into the former one end of which has previously been closed, the other end being then closed and the former rotated while in a horizontal position to distribute the latex over the layer 13. The internal pressure in the former is then raised by admitting compressed air through a valve in one end closure, and the assemblage is heated by electrical elements carried by an end closure inside the former, or by passing heated gas around the former, or by placing the former in a heated chamber. In another modification the layers 11, 12, 13 are applied to the outside of the former; in this case the layer of latex may be applied by dipping or spraying. The parting agent may be a soft wax or wax mixed with a softening agent and may be applied by means of a cloth. Sheet components of single or double curvature may be made.

Title: Improvements in Controlling Mechanism for Compound Brakes.
IPC: B60T15/30
Filed: 1916-05-09
Abstract: 106,131. Knorr-Bremse Akt.-Ges., and Hildebrand, W. May 9, 1916. Fluid-pressure. - In fluidpressure brakes employing both single and double chambered brake cylinders, and in which, during an application, air flows from the doubleeliembered cylinder, first to the single chambered cylinder and then to the atmosphere, means are provided for adapting the brakes for use with passenger trains or with loaded or unloaded goods trains. Two forms of pressure-brake valve apparatus are described, but the invention may be applied to vacuum brakes. Figs. 1 and 2 show one form arranged for use with passenger trains, but adaptable also for goods trains, and Fig. 9 shows the general arrangement in release position, in which the chamber III of the single-chambered cylinder B<1> is exhausted by way of pipe F, passages 6 - - 10, and cock H, Fig. 2, and the chambers IV, V of the double-chambered cylinder B<2> are in communication with the train-pipe L. In an application, air fows from the chamber V by way of pipe D, passages 5, 4, 11, 12, and cock H, Fig. 1, thereby raising a check valve i and flowing by passages 13, 6, and pipe F, Fig. 9, to the chamber III until the pressures are equalized, whereupon the check valve i closes, and the chamber V then exhausts to atmosphere through ports 16, 15 and cock H, Fig. 2. To adapt the apparatus for goods trains, the cock H is turned through 90 degrees, so as to throttle the passage 12, Fig. 1, and cut off the port 15, Fig. 2, from atmosphere, whereby a slower application is obtained, and the cylinder B<2> only comes into operation to a slight degree, if at all. Similarly, a slower release is obtained, since the cock H also throttles the communication between the passage 10 and the atmosphere, Fig. 2. In the second form described, adapted for loaded or unloaded goods trains according to the position of the cock H, the ports 13, 16 in the check valve are throttled, whereas the cock H provides free communication along the passage 12 and the throttled communication from the passage 10 to atmosphere in both of its positions, and cuts off the port 15 from atmosphere in the position for unloaded goods trains. Force-transmitting mechanism.-The pistons of the brake cylinders B<1>, B<2> are connected at p, n respectively to levers q, o, which are connected together by a rod r<2> having an extension r<1> attached to a lever s fulcrumed at v. The brake rods t, u are connected respectively to the levers s and q, o. q, o.

Abstract: 631,344. Fluid-pressure servomotor-control systems. WATSON, C. D., and MANSELL, R. C. S. March 10, 1947, No. 6691. [Class 135] Control surface actuating means for an aircraft comprises a master hydraulic jack, a slave hydraulic jack and mechanical transmission means whereby linear motion of the pistons of the two jacks is converted into rotary motion and is applied to differential gearing whereby valve means controlling the slave jack is set by and in accordance with movement of the piston of the master jack, and reset by and in accordance with movement of the piston of the slave jack. An embodiment shows six jacks operating aircraft flaps, but the invention may be applied to folding-wing arrangements. A master jack 17, Fig. 1, is controlled by a valve 16 via a hand lever 18. As the jack piston moves, it rotates by screwthreads a shaft 14 and bevel-gears 13, 15. The bevel 15, through a flexible drive 19, a reduction gear 20, and a spring 21, resets the valve 16. The bevel 15 also operates the valves 22 of slave jacks 31, 32 through flexible drives 29, 30, bevel-gears 26, 25, Fig. 2, and a screw 23, each valve being reset from the jack piston 10 by the rotation of bevels 13, 15, 28, 27 and a nut 24. The smaller faces of the jack pistons are always loaded by pressure-fluid from the supply. The remaining slave jacks are connected one to the other and operate similarly. In a modification, all the slave jack bevels 26 are connected by flexible drives to the master jack bevel 15. In a further modification, the bevel 15 of the jack 32 is coupled to the bevel 26 of the jack 38, as well as to that of jack 37. -
