Title: Improved fluid pressure servo-motor system
IPC: B64C11/40
Filed: 1957-10-25
Abstract: 816,818. Variable pitch propellers. GENERAL MOTORS CORPORATION. Oct. 25, 1957 [Nov. 19, 1956], No. 33376/57. Class 114. [Also in Group XXIX] A number of constant displacement pumps are so connected to a hydraulic system that the supply of liquid to the system varies from zero to a maximum in response to the system requirements. Gear pumps 10 ... 13 can supply liquid to a line 27 or 28 of a system for controlling a variable pitch propeller. The pumps and all the valves shown are mounted in a reservoir rotated with the propeller; most of the valves, with the exception of a solenoid actuated reversing valve 16 are disposed radially and therefore subject to centrifugal force. The pressure in the pressure line 27 or 28 is directed through a shuttle valve 32 to a chamber 35 of a valve 18, and aided by a spring 39 and centrifugal force urges a valve element 36 upwardly against the pressure in a supply line 14. Valve element 36 throttles a port 37 to maintain a pressure differential between lines 14 and 27 or 28. With valve 16 in its central position no liquid is supplied to lines 27, 28 and the pressure in line 14 opens port 37 and is applied to the top of a valve 42, moving the valve downwards and thus opening an exhaust port 51 and cutting off a control chamber 57 of a valve 60 from pressure and opening the chamber to an exhaust port 54. Valve 60 is thus moved downwardly by the pressure from pump 11, opening a port 68 so that pressure is applied to the top of a valve 52 which is moved downwardly to open an exhaust port 53, through which the output of pump 11 passes, and to open a control chamber of a valve 70 to exhaust. Pump 12 is unloaded through valve 70 and a valve 74, valve 74 in turn opening a control chamber of a valve 80 to exhaust which permits the output of pump 13 to pass to exhaust. If a small flow is required by the system the pressure differential falls and valve spool 36 rises to throttle port 37 to the required extent, so that part of the output of pump 10 is supplied to the system. If pump 10 cannot meet the requirements of the system port 37 closes allowing valve 42 to rise and apply pressure to the control chamber of valve 60. Valve 60 throttles its associated outlet port, and part at least of the output of pump 11 flows to line 14 through a check valve 61. If the combined outputs of pumps 10 and 11 are insufficient the outlet port of valve 60 closes, and the output of pump 12 is added. If this is still insufficient the output of pump 13 is added in like manner. The system comprises a servo motor for adjusting each propeller blade, the movement of the blades being co-ordinated by a master gear. The pumps are driven by means of gear wheels which engage a common stationary gear.

Title: Improvements in method of folding parachutes
IPC: B64D17/52
Filed: 1936-12-05
Abstract: 481,455. Pack-parachutes. CASPAR, F. A., and PAK PARACHUTE CO., Ltd. Dec. 5, 1936, No. 33382. [Class 4] A parachute comprising radial gores 10 to 18, Fig. 1, and rigging cords 11 secured between adjacent gores in seams 12 is folded for housing in a pack cover by folding the marginal portions 10a of the gores along the dotted line 21 and either over the gores, Fig. 5, or under them, Fig. 6, next folding each gore and the turned over margin along the median line as shown at 22, 22a, 23, 23a, Fig. 5, and bringing the gores together to form a triangular pile, and finally folding the pile transversely in a zigzag manner. The effect of the arrangement is as shown in Figs. 5 and 6 that the tension in the rigging lines causes the marginal parts of the gores to open into a funnel shape whereby air is directed between the folded halves of each gore and thus separates the material 22, 23 which tends to stick together in cases where the parachute has been packed for some considerable time.

Filed: 1920-11-26
Abstract: 154,550. Quick Engineering Co. Proprietary, Ltd., (Assignees of Quick, A. A.). Nov. 26, 1919, [Convention date]. Driving-gear for winding and paying-out apparatus.-Comprises apparatus such as for hauling out landfast objects in which a lever, operated by hand, by horse gear, or by engine power, acts through ratchet gearing and pulley tackle on a rope in such a manner that the rope is hauled in for each stroke of the lever, backward or forward. A frame a, anchored by a rope d, carries a combined pulley sheave and double ratchet wheel b acted upon by double pawls h pivoted on a lever g. The pawls are connected by a pin k which may be engaged by a hook j to hold the pawls out of gear. Retaining pawls l and a holding hook n are provided on the frame a. The hauling rope t is made fast to a block u, passes round a block v, which is secured to the load, to the sheave b, and round the block u to a link q which is pivoted to the lever g at a less radius than that of the sheave b. Thus, the block v, and therefore the load, is hauled towards the sheave b at each forward or backward stroke of the lever. The lever may be reciprocated, as shown in Fig. 4, by links A operated by eccentrics B on a shaft C rotated by an engine or by the horse gear shown. A sheave D is engaged by a draught-rope I which passes round pulleys F and H, the pulley H being carried by links G pivoted to other links E which carry the pulleys F and are pivoted on the shaft C. When either end of the rope I is pulled the links G swing round and jam the pulleys F, H, on the rope to some extent, ensuring a good grip of the rope on the sheave D. The bottom of the groove of the sheave b is lined with lead or other soft metal to increase the adhesion of the rope t. To renew the lead lining a leather strap is placed around the sheave, and the lead is poured in through a loop or buckle of the strap. In a modification the rope is wound on the sheave or drum b instead of merely passing round it.

Abstract: 480,042. Photo-electric apparatus for measuring objects. DESCH, J. R. Dec. 14, 1936, No. 34245. [Class 40 (iii)] Apparatus for measuring a dimension of an object comprises means for supporting the object in a collimated beam of light which is focused on a light-sensitive device controlling an indicating instrument. The support consists of a vertically adjustable platform 26 enclosed in a casing 12, on one side of which is mounted an optical system, comprising a lamp 56 surrounded by a reflector which concentrates light on an aperture 64, and a collimating lens 41 which projects parallel rays through an adjustable aperture 38 into the casing. On the opposite side of the casing is a tube closed at the inner end by an apertured member 69 and containing a lens 73 which focuses the light passing through the aperture upon a lightsensitive device 80. This is preferably a cell of the " self-energized " type, connected to a measuring instrument, the indications of which vary with the quantity of light falling on the cell. The instrument is calibrated by noting the readings obtained when objects of known heights are placed on the platform 26, which has been so adjusted that the beam falling on the aperture at 69 is intercepted by the upper edge of an object on the platform. The measurements of the heights of other objects can then be determined from the readings given when they are in the test position.
