IPC: B64C3/50
Filed: 1928-05-12
Abstract: 290,300. Peyret, L. May 13, 1927, [Convention date]. Rudders. - Surfaces of variable curvature for controlling aircraft are formed of units hinged to one another and so linked that upon moving that one of them which is pivoted on an axis carried by the aircraft the others are progressively tilted to give the desired camber to the surface as a whole. Fig. 6 shows a. supporting plane for aircraft comprising a fixed portion b and two series - of elements a, conforming to the general contour of the plane, hinged to one another and to the fixed portion at c, c<1>, c<2>. The parts are. connected together by the linkage shown so that by moving an arm d on the innermost rear section by a cable r the camber of the plane is varied as a whole, and by moving the rear leaves g on opposite sides of the machine by independent controls t the two rearmost sections of the plane may be adjusted independently of the other sections to act as ailerons. The front and rear sections may be made independently adjustable by employing fixed brackets instead of the pivoted levers g and by providing an arm d on the innermost of both the forward and rear sections. A fixed plane having ailerons in two sections similar to the rearmost sections of Fig. 6 also is described. Figs. 4 and 5 show two other methods of connecting together the sections. In the form shown in Fig. 4, arms i from one section and the next section but one extend across an intermediate section and are connected by a pin and slot. Where it is desired that one section should move in the opposite direction to another in the form shown in Fig. 6 the corresponding arm h is placed on the other side of the section, and in the form shown in Fig. 5 the cables are not crossed. According to the Specification as open to inspection under Sect 91 (3) (a) the invention may be applied to watercraft. This subject-matter does not appear in the Specification as accepted.

Filed: 1925-05-28
Abstract: 257,337. British Thomson-Houston Co., Ltd., Petch, H. S., and Harding, P. H. May 28, 1925. Electrically-tripped switches; switches, quickmake.-An electric vibratory relay comprises a reed 18 tuned to an operating periodicity and surrounded by an energizing coil and mounted in the air gap of a magnetic circuit as described in Specification 237,334, and means for using the maximum energy available in the reed for a given amplitude thereof to effect the mechanical operation of closing contacts 37 on to fixed contacts 38. The contacts 37 are carried by an arm 23 which is pivoted at 24 to a support 25 and is retained against an adjustable stop 32 by an over-set spring 27. The arm 23 has secured to it a sharp edge 31 which normally presses lightly against the underside of a flexible member 19 secured to and vibrating in unison with the reed 18. When the vibration of the reed attains a predetermined amplitude the edge 31 enters a slot 22 in the member 19; as this occurs when the reed 18 is in an extreme position, the whole of the energy of vibration is available as potential energy for the purpose of turning the arm 23 past its dead centre, whereupon the spring 27 causes the arm to turn further and close the contacts 37, 38. A resetting handle is provided for lifting the member 19 away from the edge 31 and returning the arm 23 to its initial position. The arm 23 may display an indicating disc when in its tripped position. The support 25 is fixed to a plate 33 which is secured to a base-plate 35 by a central clamping screw 34 and three, symmetrically disposed set-screws 36. The reed 18 and its operating coil are readily removable from the casing of the instrument.

Title: Improvements in or relating to the valve mechanism of internal-combustion engines
IPC: F01L1/28
Filed: 1945-06-06
Abstract: 577,740. Valve mechanism. SMITH, S. June 6, 1945, No. 14216. [Classes 7 (ii) and 7 (vi)] An internal combustion engine has an inlet valve 22 arranged concentrically within an exhaust valve 20 the latter having a tubular stem 19 sliding in a guide 17 which has a part-spherical seating 15 in the head to permit limited movement of the guide and thus allow correct seating of the exhaust valve. The cylinder head 9 has cooling water spaces 29 but the engine may be air-cooled or have the cylinder and head cast in one piece. The head has an exhaust valve seating 14 and a part-spherical portion extending to a flat top closed by a plate 40. The guide 17 has clearance in the bore 12 of the head and is prevented from rotation by a grub screw 4 which permits limited rocking movement of the guide. The cylinder-head has a pair of opposed exhaust ports 24 extending into separate exhaust manifolds 25. Two spark plugs extend horizontally from opposite sides of the cylinder head. Two interconnected channels 30 accommodate semicylindrical bars 33 which rest on ledges 34 and each bar carries four springs 32. The inner pair of springs on each bar have their ends engaging in one of a pair of grooves in the inlet valve stem while the outer pair engage in lugs 21 forming part of the exhaust valve. The two separate inlet valve springs on each bar may be replaced by a single double spring having a central U portion extending into a groove in the valve stem and retained by a cap fitting over the end of the valve stem. The plate 40 carries a casing 41 having bearings for an overhead cam-shaft 42 driven by a sprocket 43. A pair of cams 47 act through tappets 46 to control the exhaust valve while a cam 45 similarly operates the inlet valve through a recessed tappet 44. This valve may have a spherical seating in tappet 44. Preferably the cam centres are displaced from the tappet axes to cause rotation of the tappets during operation. The carburetters may be bolted directly to the top of the cam shaft casing so that the inlet gases have a vertical flow through casing 41 through the interior of the exhaust valve and the rotation of the cam shaft tends to produce turbulence in the mixture. In a modification, Fig. 4, the exhaust valve may be provided with grooves 50 having sharp upper edges and rounded lower edges to facilitate lubrication. Alternatively these grooves may be formed in the guide surface. In another modification, piston rings may be located in grooves in the guide surface. In some cases the inlet valve may move in a guide carried by a transverse rib in the exhaust valve.
