Abstract: 1465262 Stud and socket fastening AVDEL Ltd 5 Feb 1974 [5 Feb 1973] 5695/73 Heading E2B A stud 13, Figs. 1 and 9, of a stud and socket fastening has a head 26 at one end thereof and a portion at the other end for leading into a socket 15, the portion comprising a cylindrical part 36 which may be provided with a cam 37 aligned at an angle of rotation about the stud axis S relative to a diametrical portion 35 which, along with the cylindrical part 36 and a stem portion 28, forms recesses 31, 32 for receiving ends 49, 52 of respective arms 46, 47 of the socket 15. The stud 13 is mounted in a housing 16 having a circular recess 23 for the head 26 of the stud, a spring 17 therein which urges against the head 26 and against an internal flange 24 of the housing 16, and the stud is retained in the housing by a circlip 19 located in an annular recess 29 formed in the stem portion 28 of the stud. In use a panel member 11 is secured to a frame member 12 by passing the stud and housing assembly through holes in the members 11 and 12 and through a hole 53 in the socket 15, the assembly being held to the member 11 by a ring 18 which grips body 21 of the housing 16, and the socket 15, having holes 45, Fig. 2, formed therein, being fastened to the member 12 by rivets, for example. The cam 37 of the stud, having a chamfer 38, is forced against the urging of the spring 17, between the arms 46, 47 of the socket as shown in Figs. 3A, 3B and the stud is rotated by said arms to the position shown in Figs. 4A, 4B. As the stud is pushed further into the socket the arms 46, 47 are forced apart by the cylindrical part 36, and further pushing causes the cylindrical part 36 to be released by the arms 46, 47 and' the latter to spring back towards the portion 35. This causes the stud to rotate again so that the portion 35 is positioned as shown in Fig. 1 and end surfaces 48, 51 of the respective arms 46, 47 of the socket can abut radial surfaces 33, 34 of the respective recesses 31, 32. Release of the stud is effected by a screw-driver, for example, which is inserted in a slot 27 in the head 26 and rotated so as to force the ends of the arms out of the recesses. The spring 17 then urges the cylindrical part 36 from between the arms of the socket.

Abstract: 525,723. Control of D.C. motors. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Feb. 27, 1939, No. 6409. Convention date, Feb. 26, 1938. [Class 38 (iii)] In a Ward-Leonard control system the generator G is provided with an auxiliary field winding GF2 the current through which is automatically controlled to cause the motor M to run at a constant speed as preset by a control switch CS. This is effected by means of an auxiliary generator R which has four field windings; a pair RF1 and RF3 connected respectively in parallel and series with the motor M and acting in opposition to give a field proportional to the speed of the motor; a third RF2 in series with the main field GF1 of the generator G and giving a field roughly proportional to the generator voltage and acting in opposition to the resultant field produced by the first pair; and a fourth field RF4 which is a series field adjusted to produce for a given current therein, a voltage in the armature just sufficient to cause that current to flow in the field, and is in series with the auxiliary field windings GF2. Movement of the switch CS in one direction or the other first closes the circuit of a relay 14 which removes a brake from the motor and also energizes the field winding GF1 for forward or reverse running. Further movement of the switch CS removes resistance from the field GF1 to vary the speed of the motor M to give connection in dependence of temperature thermostats T1, T2 .are provided which remove resistance r3, r4 from the circuit of the field GF2.

Title: Pitch change actuator for a variable pitch ducted fan propulsion assembly
IPC: F01D7/00
Filed: 1974-02-13
Abstract: 1454232 Ducted fan engine; pitch change actuator UNITED AIRCRAFT CORP 13 Feb 1974 [21 Feb 1973] 6545/74 Headings FIC and F1J A ducted fan propulsion assembly having a plurality of circumferentially spaced blades, comprises harmonic drive means operatively connected to the blades, and means for imparting a pitch change input signal to actuate the harmonic drive to vary the blade angle. The insertion is described with reference a pitch change means, Fig. 4 in which the blades 232 are supported in a hub 234 which is driven by an engine. The hub carries a ring gear 228 which co-operates with a sun gear 224 through planetary gears 226. The pitch change input signal is applied through a pitch lock 220 to a gear 222 which is in mesh with a gear 218. Gears 218 and 224 are formed on a sleeve which is rotatable relative to a grounded shaft 204. The planetary gears 226 are mounted on shafts which carry planetary gears 208. The gears 208 mesh with a grounded sun gear 206 and a ring gear 210 of the harmonic drive. The hub and the disc 212 carrying the ring gear 210 rotate at the same speed until an input signal is fed to the gear 222. Relative rotation between the two then takes place. A flexible fixed cylinder 250 having gear teeth is deflected into an ellipsoidal shape by virtue of the similarly shaped rigid disc 212. The teeth of the flexible cylinder on the major axis engage teeth on a gear 260 which is in mesh with teeth on the blades. The major axis rotates relative to the hub due to the input signal and the gear 260 moves accordingly to vary the blade angle. The pitch lock Fig. 7 comprises a bore 300' having within it a coil spring gripping the bore by friction. The blade shaft 326' carries a tang 328' which engages one of two tangs on the spring should it try to rotate out of position. Such engagement increases the friction between the spring and the bore. The input signal is applied through splines 312' or 314' according to its sense. The engagement of a spline and a spring tang reduces the friction between the spring and the bores and allows the blade to rotate in the hub. In the particular embodiment of the propulsion unit described, a centre shaft (28) Fig. 2, (not shown) is driven by the engine, the blades and hub being driven via fixed idler gears (40) and gear ring (42) which are mounted forwardly of the pitch lock (32), harmonic drive (36) the blade segment gears (68).
