Title: Improvements in non-refillable bottles
IPC: B65D49/06
Filed: 1947-04-21
Abstract: 633,436. Non-refillable bottles. FAIRWEATHER, H. G. C. (Inter-Seal Corporation). April 21, 1947, No. 10640. [Class 125(i)] A non-refillable fitting of the kind comprising a valve with a superposed float and weight, consists of sleeves 10 and 27 held on the bottle neck by a ferrule 35. The sleeve 10 has a post 13 with a rounded seat, with which coacts a hollow valve 17 having a seating surface 19a and a skirt 20 spaced by a slight clearance from the wall of the port 13. The valve stem 21 enters a recessed part of the float 23 and is guided therein by tapered ribs. The stem has a capillary vent hole 22 which is at the bottom of a cup-shaped cavity and coacts with a rounded boss at the bottom of the recess in the float. The valve and float are guided by tapered ribs 14 on the sleeve 10. The float is open at its upper end, which is engaged by the ball weight 26. The latter is guided by a conical shield 30 which is guided by ribs 31 for limited outward movement in the sleeve 27 and is secured to a disc 33 adapted to close the upper end of the sleeve 27. The guide surfaces on the casing and float member are made of synthetic resin materials which slide smoothly on one another. If both are formed of polystyrene, one is slightly roughened by dipping in a solvent. Alternatively, one member may be made of polystyrene and the other made of or coated with polyethylene. The float member may be made of polystyrene and then the valve is preferably made of polyethylene. The float member may be open at its upper or lower end. In the latter case, the upper end of the member is counterweighted to provide the greater buoyancy at the end adjacent the valve. The latter may have a buoyant plug at its lower end. The lightness of the valve and float, their freedom to slide, and the tension of the film of liquid which forms in the small clearance around the valve skirt, reduce the tendency of the valve to open if an attempt is made to refill the bottle fraudulently by agitating or vibrating it. The counterweighting of the float member reduces binding of the float and valve on the ribs 14 and so facilitates closing of the valve if an attempt is made to refill the bottle with the latter at a small angle to the horizontal. This effect is supplemented by the tendency of the ball 26 to roll on the conical shield towards the float. Any vacuum in the bottle is relieved by the vent 22 as soon as the float moves upon tilting the bottle to pour out its contents. Specification 11519/46, (as open to inspection under Sect. 91), is referred to. The Specification as open to inspection under Sect. 91 describes also a closed float member of similar buoyancy at both ends. This subject-matter does not appear in the Specification as accepted.

IPC: B64B1/58
Filed: 1925-04-28
Abstract: 240,123. Luftschiffbau Zeppelin Ges. Sept. 18, 1924, [Convention date]. Aerostats.-The runs or strips of fabric of which the outer envelope of a rigid airship is made up, are formed of two materials, the major inner part being composed of light material, and the bounding parts being composed of stouter fabric. Alternatively, the bounding portions may be of a material woven differently from the inner part. Fig. 1 shows adjacent portions of a number of runs consisting of inner parts a of a light fabric, such as cotton, surrounded by bounding portions b of thicker material. At the corners of the runs strengthening pieces c are sewn, which in order to provide effective transmission of the strain are composed of elastic material such as india-rubber. These pieces are attached to the runs by seams d which extend radially from the eyelets e in the direction of the stress, and the threads of which are not tied or knitted but run freely out at the ends to obtain a resilient connection. On the edges of the runs transverse strengthening strips f are sewn; at places were the strain is considerable these strips may extend over the entire width of the run. The lacing eyelets are formed in separate strips of material h, Fig. 3, attached to the edges of the run. The strips h are formed of a piece of material folded so that one edge overlaps the other. A single thickness of the run is first attached by a seam i, and then the run is folded over and stitched by a further seam k to the edge of the strip h. All the seams in the envelope which run in the direction of the warp or weft of the fabric are stitched in waved or broken lines, and where possible overlaps in the fabric are made so that air resistance is avoided.

Title: Improvements in or relating to Nuclear Reactor Fuel Element Assemblies
Inventor: CHETTER JOHN
IPC: G21C3/356
Filed: 1966-07-21
Abstract: 1,186,518. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 13 July, 1967 [21 July, 1966; 8 March, 1967], Nos. 32911/66 and 11018/67. Heading G6C. A spacer grid for a cluster-type nuclear fuel element comprises a grid structure of cellular form, the cells of which are penetrated by fuel pins, the grid structure defining two spaced stop means for each fuel pin, and resilient means carried by the grid structure to hold each fuel pin against the spaced stop means, the resilient means and the two stop means for each fuel pin being positioned at the corners of an isosceles triangle. In a portion of such a grid structure shown in Fig. 9, a series of parallel strips 20, 21 are intersected at right angles by a strip 22 formed of cojoined lozenge-shaped sections 29. The sections 29 have recesses 30 in their upper and lower edges which serve to accommodate and locate looped spring members 31. Each of the sections 29 is slotted longitudinally and deformed to form two loops 32 extending from opposite faces to serve as spreaders for the spring members 31. The strips 20, 21 are split at spaced positions along their length and deformed at each position on either side of the strip at two levels to provide loops 25. The loops 25 form the stop means against which the fuel pins are held by the spring members 31. The strips 20, 21, 22 are of stainless steel edge on to the coolant flow while the spring members 31 are of nickel alloy. The spring members 31 are in the form of two bow springs spot-welded together at their ends. In a modification, shown in Fig. 12, designed to prevent the formation of a coolant void downstream of the contact point between pin and spring which could produce a local hot spot in the fuel pin sheath, the spring member comprises a double-limbed spring 60 encircling a grooved strip of the grid structure and has on each limb 61 a pair of laterally extending integral arms 62 each provided with a curved contact surface 63 providing for surface contact with the sheaths of a pair of adjacent fuel pins. The contact areas are outside the width of the limbs 61 and thus provide passages 64 for coolant flow between the limbs 61 and the fuel pins. A continuous film of coolant can thus exist between the main body of the spring and the surface of each fuel pin, thereby avoiding undesirable effects resulting from interference with the coolant flow pattern downstream of the spring member.
