Filed: 1940-04-03
Abstract: 540,911. Pneumatic single stroke apparatus. GREEN, D. S. April 3, 1940, No. 6018. [Class 8 (ii)] [Also in Group XXIX] A telemotor fluid control system, in which the movement of transmitter piston 7 induces a corresponding movement in a receiver piston 6 in a casing connected to the casing 3 of the transmitter system by a pipe line 5, is constructed so that the casing 3 or the casing of the receiver serves as a reservoir for the operating fluid. The invention can be applied to aeroplanes, and the operating oil may be inserted through an opening closed by a plug 22, or if a gaseous fluid is employed a valve replaces the plug. The piston 7 is operated by a rocker plate 11 fitted with a handle 13, and a sealing washer maintains a fluid-tight joint between the plate 11 and the slot in which it works. The piston 7 is kept fluid-tight by packing devices 15, 16, 17, and at the end of an operative stroke of the piston 7 a valve 26 is opened by a rod 29 operated by a lever 31 and a cam on the shaft 12 of the plate 11 in order to permit passage of oil from the casing 3 to the cylinder 4. To balance pressures so that the transmitter will remain in a set position, the plate 11 is spring-loaded by means of a spring 34 located between an anchorage shaft 35 and a member pivoted at 36 to a link 37 which causes the product of leverage and compression to be substantially constant. The casing 3 is flat sided. The receiver can be constructed similarly to the transmitter. Specifications 419,310 and 527,074, [both in Group XXIX], are referred to.

Abstract: 380,722. Universal joints. RUDQVIST, C. A., Liding÷, Sweden. March 4, 1932, No. 6603. Convention date, March 6, 1931. [Class 80 (ii).] In a universal joint of the kind wherein a resilient disc 14 is bolted at six points alternately to coupling flanges 12, and a body such as a hardened steel ball 20 is arranged to take axial stress, the body and/or the flanges or shaft ends are so formed as to permit relative lateral movement of the coupled shafts by rolling or sliding between the body and the flanges. The form shown in the Figure takes axial stress in both directions, the ball 20 being embraced by the interengaging curved arms 21 of two three-armed spiders, bolted one on each side of the resilient disc, preferably by the same bolts 15 which are used for attaching the disc to the flanges. To permit the required relative lateral movement, clearance is left between the bolts and the holes in the spider arms, or between the ball and the arms. The ball engages the flanges through central apertures in the spiders, either directly or through bearing-pieces 33. The resilient disc comprises several layers of metal or rubber, which may be reinforced by flanged rings 32. In a simpler form wherein the ball takes only compressive axial stress, the spiders 21 are omitted, the ball resting freely in a central aperture in the resilient disc. The ball 20 may be replaced by a plane plate bearing on curved surfaces on the flanges.
