Abstract: 685,490. Linear-dimension gauges. GOLDSBURY, F. E. June 29, 1951 [Oct. 19, 1950], No. 25525/50. Class 106 (ii). A micrometer gauge for taking internal measurements comprises a rigid U-shaped body 10 having a plunger 29 in one limb 13 and a micrometer screw in the other limb 12, a fixed jaw member 21 on the limb 12 and a movable jaw member 31 on the plunger 29, the two jawmembers projecting outwards side-by-side in a plane perpendicular to the micrometer screw axis. The plunger 29 is resiliently urged against the tip 17 of the micrometer screw and, when desired, the movable jaw member 31 is secured to the plunger 29 by screw means 32. In use, the two jaw members are allowed to remain in engagement with each other while the head 48 is turned to give a reading on the scale 44 that equals the known thickness between the outer tip portions 26 and 35 of the jaws, say 0.1 inch. The screw 32 is then tightened and the micrometer may then be used for measuring internal dimensions between 0.1 and 1 inch. Alternatively the movable jaw member 31 may be moved along the plunger 29 to any other position which is convenient for the measurement range desired, the resulting necessary correction to the reading on the scale 44 being ascertained by inserting trial gauge blocks, a measuring-rod or equivalent means between the internal faces 25 and 34 of the jaws 21 and 31, respectively. In Fig. 1 the jaws 21 and 31 lie in the plane of the micrometer but they may, alternatively, extend in a plane that is perpendicular to the plane of the micrometer. In Fig. 5, the modified arrangement and shape of the jaws 24b and 31b enables the micrometer to gauge internal distances of 6 inches or more, the larger dimensions being made possible by the use of a plunger 29c extending beyond the limb 13 with a movable jaw member 31c thereon. The spring 37 is operatively connected with the plunger 29 at 39, Fig. 1, in a manner preventing angular movement of the plunger 29 about its axis. The projecting end 29a of the plunger 29 also serves as a depth gauge, using the surface 15a of the body as datum.

Abstract: 842,012. Valves. DOWTY NUCLEONICS Ltd. Aug. 21, 1957 [Aug. 22, 1956], No. 25602/56. Class 135. A combined distributing and shut-off valve for monitoring the cooling gas of a nuclear reactor to detect contamination by fission products comprises a valve body 1 provided with a series of axially-spaced ports 24, 25, 26, 27 communicating with the ducts of a group of fuel elements, a passage 19 in communication with the monitoring apparatus, an outlet 6, and a cylindrical bore 23 receiving a rotary plug member 22 with four axially-spaced projections 33, 34, 35, 36 provided with ports 37, 38, 39, 41 registrable with the body parts 24 ... 27 in different angular positions of the plug, the latter further being provided with an axial bore 42 and engaging a rotary valve disc 43 bearing against a fixed disc 46, whereby in one position of the plug (when rotated 180 degrees from the position shown in Fig. 1) the disc 43 isolates outlet 6 from bore 23, while in other positions flow may take place between outlet 6 and those of ports 24 ... 27 which may be uncovered by projections 33 ... 36. The fixed disc 46 is secured to the valve body by a pin 48, and is provided with a single eccentric port 55, Fig. 3, in permanent communication with outlet 6, and a pair of diametrically-opposite central ports 57. Rotary disc 43 is secured to plug 22 for rotation therewith by a pin 45, and is provided with five eccentric ports 49, 51, 52, 53, 54 angularly spaced at 60-degree intervals, Fig. 4, and a pair of central ports 58. The ports 57, 58 are so arranged that they coincide to provide a flow path only when one of the plug ports 37 ... 41 is in register with its associated wall port 24 ... 27. Discs 43, 46 are pressed into contact by a spring 40 in the axial plug bore 42. The angular spacing of the ports in disc 43 enables plug 22 to be set in any one of six positions by means of a key applied to the end of a spindle 62 which is normally covered by a screw cap 65. In the position shown in Fig. 1 ports 57, 58 do not coincide, so that discs 43, 46 cut off communication with passage 19, but gas flowing through ports 24 ... 27 may pass around plug 22 and through ports 49, 55 to outlet 6. If the plug be rotated through 180 degrees from this position, discs 43, 46 still cut off passage 19, while in addition the unported portion of disc 43 obstructs port 55 in disc 46, so that communication with outlet 6 is also cut off. In any one of the remaining four positions gas passes through one of the wall ports and the associated plug port, through axial bore 42 and ports 57, 58 to passage 19, while the gas passing through the remaining three wall ports may pass to outlet 6. To ensure sealing between valve discs 43, 46, they are made of stainless steel with optically flat mating faces, but according to the Provisional Specification the fixed disc 46 may be made of nylon or carbon.
