Title: Improvements in or relating to planes for aircraft of the helicopter type
IPC: B64C27/26
Filed: 1926-03-16
Abstract: 274,534. Oldfield, W. R. March 16, 1926. Screw propellers.-The wings of a freely rotating wing-system are built up of telescopic sections which may be collapsed or extended longitudinally at the will of the pilot. In the machine described, the wing-system comprises four planes 2 connected by hinge fittings 4 to a freely-rotatable mast 6 mounted in a bearing 9 carried by the fuselage. The planes 2 each consist of a number of telescopic sections 3 of sheet metal covered externally or internally, or both, with fabric, and of progressively increasing thickness and width towards their tips. The outer open end of each section is braced by ribs 26 attached to angle pieces 27 which may be hinged to facilitate removal of the ribs. The sections are of tapering thickness so that when they are extended a wedge action is set up : the joints may be made .airtight by interposing rubber packing. The innermost sections are reinforced by tubular stays 21 braced, if desired, by tie wires. The planes are normally held collapsed by tension wires 12 incorporating springs or elastic cords and connected to the outermost sections, which also carry weights 28. A modification is referred to in which the sections 3 decrease in thickness and width towards the tips. The mast 6 is fitted at its base with a friction clutch 16, 17 operable by a lever 18. Normally this clutch holds the wing-system against rotation at which time the planes 2 are collapsed by the tension wires 12. When the clutch is released, the wing-system is rotated by the air stream and under centrifugal action aided by the weights 28 extends against the tension of the wires 12. If desired the main planes 8 may be made to telescope under the control of the pilot so that they may be collapsed when the rotary wing system is extended.

Title: Pressure sensitive resistance elements and process of making  same

Filed: 1974-02-20
Abstract: 1460082 Pressure-sensitive resistors DYNACON INDUSTRIES Inc 20 Feb 1974 [26 Feb 1973] 7726/74 Heading HIS [Also in Division C3T] A pressure-sensitive resistor comprises conductive particles of a size between 0À1 and 44 microns dispersed in cured elastomeric resin, a semi-conductive layer being formed at the interfaces of the particles with the resin. This layer may be produced by mixing the conductive particles with both a polymerization catalyst and a polymerization inhibitor before adding the particles to the resin which may be incompletely cured at the interfaces. Alternatively an already semi-conductive material may be added to the particles. The resistor may be in strip form. The conductive particles may be of iron, copper, chromium, titanium, tungsten, platinum, boron, steel, silicon, silver, gold, nickel, cobalt, aluminium, zinc, tin or carbon, preferred materials being nickel, mercury-coated nickel and silver-coated nickel, and carbon mixed with other conductive particles. The resin, which may contain a filler, is preferably a silicone elastomer which is curable either by a peroxy catalyst or by a metal soap catalyst. In each case both peroxy and metal soap materials are pre-mixed with the conductive particles, one material acting as the polymerization catalyst and the other as the inhibitor. An aryl compound is also preferably included. One embodiment described demonstrates a pressure polarizable effect when subjected to given conditions of pressure and voltage, an instant return response being obtained upon reversing the applied polarity; this may be employed in memory devices. The resistance of the resistor varies under tension, as will as when compressed, and may be anisotropic.

Abstract: 805,251. Clutches. MASSEY-HARRISFERGUSON, Inc. March 17, 1955 [March 17, 1954], No. 7809/55. Class 80 (2). A double clutch for coupling the engine shaft with two driven shafts of a tractor for driving the ground wheels and a power take - off respectively comprises a flywheel 10 on the engine shaft 11 having a peripheral 20 and an annular casing member 21 secured thereto, axially shiftable clutch plates 25, 26 rotatable with the flywheel and clutch discs 30, 36 on driven shafts 14, 15, respectively, disposed between the clutch plates 25, 26 and the flywheel and casing 10, 21. Both clutches are loaded to engage by a common spring 27 and actuated to disengage successively by a sliding collar 41 operating levers 45 which are pivoted at 46 on the ends of thrust-rods 47 slidably received in holes through the flywheel 10, clutch plates 25, 26 and casing member 21. The levers 45 are also each provided with a fulcrum point 53 co-operating with an abutment 52 of the member 21 and an adjustable fulcrum piece 51 co-operating with one of a series of thrust pins 50 extending through holes in the member 21 and clutch plate 26 and engaging clutch plate 25. The thrust rods 47 have collars or circlips 48 abutting the plate 26 so that on actuation of the collar 41 to the left the levers 45 pivot about 46 to move rods 50 to release the clutch disc 30 and pivot about the fulcrum point 53 to move rods 47 to release clutch disc 36. Return movement of collar 41 re-engages the clutches in reverse order to disengagement. In a modified arrangement the clutch disc 30 is arranged between the flywheel 10 and the clutch plate 25 and the clutch disc 36 between the plates 25 and 26, the loading spring being between the casing member 21 and the clutch plate 26. The actuation is, however, similar.
Patent GB-580842-A (GB)
Title: Improvements relating to the manufacture of machine parts
IPC: C21D6/02
Filed: 1941-06-20
Abstract: Relates to the manufacture of a machine part, furnace part, or other element which must work under stress at a given high temperature and must therefore have high creep resistance.  An alloy of a type having appropriate characteristics for the general requirements of the case is selected, and the solid solubility at the temperature in question of an element or combination of elements capable of forming a precipitable phase in the alloy is ascertained.  The machine, furnace, or other part is then made from an alloy which contains an amount of the said element or combination of elements that is greater, but not more than 2 per cent. of the total alloy greater, than the solid solubility so determined.  The part is then heated to a high temperature, which is always above the temperature at which the part must work, for long enough for the alloy substantially to reach equilibrium, cooled sufficiently rapidly from this temperature to maintain substantially all of the solution formed during the heating, and then reheated to break down the state of supersaturation and to cause the precipitable phase to precipitate in a fine and uniformly dispersed form.  In an example, an alloy of the 80 per cent. nickel-20 per cent. chromium type containing 2 per cent. silicon, is stated to dissolve 2.1 per cent. titanium at 800 DEG C. An alloy of this type containing more than 2.1 per cent. but not more than 4.1 per cent. titanium is put into the best condition for creep resistance at a service temperature of 750 DEG C. by heating for 24 hours at 1100 DEG C., cooling rapidly from this temperature, and reheating for 72 hours at 800 DEG C.  Certain figures of the drawings show by means of graphs how the creep resistance varies with the presence of varying amounts of the precipitable phase and the alloy. Certain other figures show how the solid solubility of the precipitable phase in the base alloy varies with temperature, and certain other figures show how the solid solubility of one precipitable phase is affected by the presence of a second precipitable phase.

Abstract: 723,665. Machinery safety devices. NATIONAL COAL BOARD. May 27, 1953 [May 27, 1952], No. 7894/52. Class 80 (4) [Also in Group V] The flywheel 1 of a brick press, which descends during the working stroke of the press (see Group V) is prevented from falling when the flywheel is in the raised (idle) position by two strut-like arms 25A, 26A forming parts of bellcrank levers pivoted at fixed points 25C, 26C. The other arms 25B, 26B of the levers are connected through a bar (not shown) to a lever 27 having a pin-and-slot connection with a bellcrank lever 29, 30 pivoted at a fixed point 41. Lever arm 30 is joined by a link 31 to a handle 4. In the idle position shown (the brick-pressing ram being raised), the upper ends of the struts 25A, 26A lie under the flywheel and prevent its descent. When the handle 4 is pulled to the left, Fig. 1, to cause descent of the flywheel and ram, the connections 31, 30, 29, 27, &c. move the struts to the dotted line position, Fig. 2, in which they do not obstruct the flywheel.
