Title: Disconnectable tube coupling
IPC: F16L37/23
Filed: 1964-04-16
Abstract: 1,000,961. Pipe couplings. UNITED STATES ATOMIC ENERGY COMMISSION. April 16, 1964 [June 17, 1963], No. 15797/64. Heading F2G. A quick-disconnect coupling comprises an outer member 11 formed of two adjustably inter-threaded parts 16, 17 having an internal shoulder 22 abutted by a gasket-ring 12, an inner member 10 inserted therein and having an end abutting said ring, and means releasably connecting the inner member with one part of the outer member, whereby rotation of said one part advances the inner member, thereby increasing gasket compression between the shoulder and the end of the inner member. Said means comprises an outer spring-loaded sleeve 14 retaining balls 13, which project through peripheral holes 20 in the outer member, in a groove 21 of the inner member. The outer member parts are initially adjusted to permit interlocking of the inner and outer members and abutment of the gasket ring by the inner member without the necessity of using great force. The part 17 is then rotated relative to the part 16 to increase the gasket ring compression between the shoulder 22 and the end of the inner member. The gasket ring, which is located in a groove 23 adjacent the shoulder, may be of a relatively hard material such as polyfluortetraethylene resin, asbestos compound, gold, copper, lead, tin or tantulum, or may be of relative soft material, such as soft rubber. In the latter case, relative adjustment of parts 16 and 17 to increase gasket ring compression may be unnecessary.

IPC: F16K27/06
Filed: 1970-04-07
Abstract: 1303316 Valves ROCKWELL MFG CO 7 April 1970 [10 April 1969 30 March 1970] 16297/70 Heading F2V A valve comprises a body having a chamber in which a closure member is movably mounted to control fluid flow between points adjacent the chamber and a flow transition region extending from at least one of the points to one end of the body and having boundary walls which diverge at an equivalent cone angle substantially in the range from 6 to less than 20 degrees and terminate in an abruptly enlarged section C, Fig. 4. When the valve has a flow passageway of non-circular cross-section the rate of change of cross-sectional area with length in the transition region determines the equivalent cone angle. The provision of the section C enables the overall length of the valve to be reduced with minimum pressure drop. A radius r having a value of up to one quarter of the diameter D of the conduit to which the valve is to be connected joins the section which has an equivalent cone angle of more than 60 degrees with the remainder of the transition region. The conical section C may be replaced by a recess 52 as shown in Fig. 5. An internal thread may be provided in a parallel bore at the outer end of the transition region to receive a threaded end on a conduit. Alternatively, the region may be terminated in a manner suitable for butt or socket welding to a conduit. The cone angle is preferably in the range of 10 to 14 degrees and the invention may be applied to plug valves with circular, rectangular or trapezoidal parts or to ball, gate or globe valves.

The wheels b are double and may run on either the top or bottom flanges of the rail i. A load platform may be supported on the member a, and the carriage may be driven by a motor through a pinion gearing with a fixed rack. In the construction shown in Fig. 5 each rolling member r comprises an elongated member s and a series of wheels t linked together, the rolling members being connected together by links u. A pinion p carried by the main member a gears with a fixed rack q.

Abstract: 401,779. Number-printing apparatus. ADDRESSOGRAPH - MULTIGRAPH, Ltd., Edgware Road, Cricklewood, and LINGARD, F. E., 238, Brentfield Road, Willesden, both in London. June 10, 1932, No. 16469. [Class 100 (ii).] Number-printing mechanism for use in addressing &c. machines comprises a pivoted member supporting a numbering-device, and a lever pivoted to the member and connected to a cam which on actuation of the lever moves the device into or out of operative position. As shown, a numbering-device 20, Fig. 2, arranged adjacent to an address-plate 21 in printing position is carried by a frame 18 pivoted at 19. The number wheels are advanced by means of a slide 29 connected to a lever 26 pivoted at 27 to the frame 18 and connected by a link 30 to a cam 23 adapted to raise the frame 18 or allow it to fall into an inoperative position : a similar cam 22 is manually adjustable by means of a push rod 24. The lever 26 is rocked by a rod 11 actuated by the known mechanism shown in Fig. 1 whereby, on the downward movement of a platen arm 14<1>, an arm 1 from which the plates are fed is moved anticlockwise prior to a feed stroke and oscillates a lever 5 carrying a notched bar 15 adapted to engage the end of the rod 11. The mechanism is adapted (a) to repeat a number in association with each of two or more impressions printed from one plate with the exception of the final impression, as required, for instance, in two column listing ; (b) to print a number in association with the final impression only ; (c) in consecutive printing to print consecutive numbers ; (d) to be put entirely out of action. (a) The cam 22 is adjusted so as to be clear of the frame 18 whereby the bar 11 on its movement to the right during an impression stroke and prior to an address-plate feed stroke rotates the cam 23 to allow the frame 18 to drop and moves the bar 29 to the left. Subsequently, on the return movement of the platen arm, the numbering-device is raised into printing position and the number wheels are advanced, the parts remaining in that position until the final impression of the next series. (b) The cam 23 is adjusted relatively to the lever 30 so that the frame 18 is lowered after instead of before the final impression. (c) The cam 22 is adjusted to raise the frame 18 and retain it in the operative position. (d) Both cams 22, 23 are turned so as to lower the frame, a push rod 34 being provided to slide the bar 29 to the left and turn the lever 26 ; alternatively, the link 30 might be disconnected in which case the number wheels are still advanced. The provisional specification describes an alternative method of actuating the rod 11 comprising a slotted plate attached to the lever 1. Specification 311,357, [Class 100 (ii), Printing processes &c.], is referred to.
