Title: Improvements in and relating to artificial feel systems for aircraft controls
Inventor: CREASEY RAYMOND FREDERICK
IPC: B64C13/46
Filed: 1953-03-10
Abstract: 737,812. Controlling aircraft. ENGLISH ELECTRIC CO., Ltd. March 5, 1954 [March 10, 1953], No. 6649/53. Class 4. In a feel simulator system the ratio of the restoring force upon the pilot's control member, for a given deflection from its neutral altitude, to the dynamic pressure, remains at a substantially constant value over a range of aircraft speeds up to nearly sonic speed and then falls off rapidly over the range of aircraft speeds through and above sonic speed. In one arrangement, Fig. 1, the pilot's control member 1 is coupled to the piston 6 moving in a hydraulic cylinder 3 pivoted! to the aircraft structure. A valve 31 controls the pressure of the fluid in the cylinder 3 and is operated by a lever 34 one end of which rests on the face of a capsule 35. The casing 37 within which the capsule is mounted is connected through a pipe 38 to a source of static air pressure. The interior of the capsule may be connected by a pipe 36 to a air intake 30 arranged on the surface of the fuselage or a nacelle and so proportioned and placed that at supersonic speeds its shock wave separates the boundary layer in front of it so that the excess pressure in the intake over the static pressure is substantially proportional to dynamic pressure up to nearly sonic speed and then falls off rapidly from this proportionality. The capsule 35 may be provided with an interior evacuated capsule which acts as a compression spring on the inside of capsule 35. In another arrangement, Fig. 5, the interior of capsule 35 is connected by the pipe 36 to a chamber 42 which is connected through a restricted orific 41 and pipe 40 to a pitot tube (not shown). The chamber 42 is also connected by a pipe 43 to the interior of a capsule 44 arranged within an evacuated capsule 45. A chamber 46, within which capsule 45 is placed, is connected to a source of static pressure by a pipe 48 and to the chamber 42 by a valve 47 which is controlled by the combined capsules 44, 45. Spring 49 loads the capsule in the sense of tending to close valve 47. By suitable arrangements of the geometry and the spring rates'of the capsules and the spring, the valve 47 can be arranged to open near sonic speed and the pressure in the chamber 42 and pipe 36 can be made to follow the required characteristic. Specification 727,513 is referred to.

Title: Improvements in electric arc welding apparatus
IPC: B23K9/14
Filed: 1939-03-02
Abstract: 509,232. Uniting by fusion. BRITISH THOMSON-HOUSTON CO., Ltd. March 2, 1939, No. 6861. Convention date, March 2, 1938. Addition to 472,036. [Class 83 (iv)] In an arc welding apparatus of the kind in which a bare wire electrode is continuously fed to the work and flux paste is applied thereto through an axially movable nozzle which surrounds the wire and is connected to a pump, as described in the parent Specification, the nozzle is moved along the wire in such a manner that the relative movement between the wire and nozzle is constant so that the paste is uniformly applied to the wire in spite of variation of the speed of the wire feed. The electrode wire 1 is fed from a welding head under control of a relay so as to maintain the length of the arc constant. Surrounding the wire is a nozzle 4 to which may be secured or welded an electric contact piece 9 connected to the current supply and on which are mounted spring-pressed rollers 11, which are driven at a uniform speed by a motor so that the nozzle tends to travel upwards. The rollers are preferably fluted and provided with pawls so as to prevent slipping and reverse rotation. To the nozzle is connected either a container 5 for flux paste and a pump 7, or a flexible conduit connected to a pump mounted on the machine, the pump supplying a uniform quantity of paste at any time. The pump and rollers are preferably driven by a common motor. If burning is uniform, the nozzle is at rest. If due to great burning away of the wire, the feeding speed is increased, the nozzle 4 moves in the same direction as the wire. If the feeding speed of the wire decreases due to insufficient burning, the nozzle moves upwards on the wire. The relative speed between the wire and nozzle thus remains the same. The upward and downward movements of the nozzle may be limited by stops. On contact with the upper stop, increase of welding current strength results, and on contact with the lower stop decrease of current strength and the speed of the wire is consequently varied. The relative speed of nozzle and wire can be varied at such times. For this purpose, the motor which operates the rollers 11 and pump may be regulated by a resistance on which slides a contact secured to the nozzle.

[Class 83 (iii).] In a drilling - machine having a centrifugal feed the frame 1 has rotatable therein a bush 2, in which is splined the drill spindle 9. Lugs 3 on the bush carry pivots 4 for links 5 pivoted at 6 to arms 7 which are pivoted at 8 to a single eye on the spindle 9. Two semicircular weights 10 are attached to the arms 7 and serve to depress the spindle under centrifugal action when the spindle is rotated by a bevel pinion 26 splined thereon and a hand or power driven bevel gear 27. The weights also withdraw the drill when rotation ceases and are cut away at 17 to clear the spindle and links 5 when in the inoperative position shown in the Figure. Nuts 14 operating on screwed portions 13 of the arms 7 adjust the positions of the weights relatively to the pivot 8 to vary the feed pressure, and the connection of the links 5 to the arms is varied by means of holes 12 for the pivots 6. The bush 2 has an integral collar 19 and a removable collar 22 secured bv a screw 23, a fibre washer 20 and a ball thrust bearing 24 being placed between the respective collars and the bearing 25. The frame 1 is attached to a bench &c. by a clamp 32 and a vertically adjustable work-table 29 is secured in the frame by a screw 30.

Title: Improvements in the manufacture of lead silicate frits and enamel fluxes
IPC: C03C8/14
Filed: 1947-03-12
Abstract: 625,474. Coated enamels &c. PODMORE & SONS, Ltd., W., and PODMORE, H. L. March 12, 1947, No. 6909. [Class 56] Finely ground particles of lead silicate frits and enamel fluxes are coated with a thin layer of a material which is impervious to and insoluble in weak acid solution. Alkali or organo silicates may be used, e.g. a coating may consist of silica gel formed by the hydrolysis of an alkali silicate, or of ethoxy polymers formed by the condensation of ethyl silicate or ethyl silicate cellulose nitrate lacquer. In one example the frit is wet ground so that 95 per cent passes a 200 B.S.S., deflocculated, the particles of less than .01 mm. diameter removed and the remainder dried and disintegrated. The powder is then mixed with a partly hydrolysed solution of ethyl silicate in aqueous ethyl alcohol, such that a gel is formed soon after the surplus liquid is filtered off. The coated frit is air dried, at not more than 200‹C, and disintegrated. The resultant is not attacked by gastric juices and the danger of lead poisoning among enamelling operatives is thereby reduced. When two separate coatings are applied in this way a more effective product is obtained.
