Title: Improvements in or relating to hydraulic jacks
IPC: B66F3/30
Filed: 1941-06-24
Abstract: 550,286. Hydraulic jacks. ROTHERI, J. S., SWANSON, J. M., and RUGGINS, W. G. June 24, 1941, No. 7950. [Class 78 (iii)] To prevent return of the ram 7 of a hydraulic jack owing to leakage after the working stroke is completed, a loose collar 10, perforated with a plurality of aligned holes 11, is located rotably round the ram at the point of its emergence from the cylinder 2. The ram 7 has at intervals similar oppositely placed holes 8, and a pin 14 is thrust through these and through the holes 11 in the collar 10 which come into alignment therewith. The holes 11 are arranged on a double helix and may be elongated along their helical axes. Alternatively the collar may screw on to a threaded extension of the cylinder to attain alignment with less possibility of back lash. The collar 10 rests on a flanged sleeve 9 closing the upper end of the cylinder 2, and a vent 28 is provided in the cylinder wall to release fluid when the ram attains its maximum outward travel, a one-way valve allowing excess fluid to pass by way of a duct 30 to the reservoir, which may consist of the tubular legs and struts of the jack. The use of the sleeve 9 is stated to preclude the employment of a packing gland in this location, and to lessen leakage between ram and cylinder the usual cup leather 16 is supplemented by an expansible packing 15 compressed by a spring 28 bearing on the flanges 24, 27 of two sleeves 23, 26 slidable on ram and in cylinder. The packing 15 is built up of two packing rings 20, 21 the contiguous faces of which have triangular or circular mating conformations of dissimilar size so that the upper ring 20 has its lower edge forced out by the pressure thereon of the lower ring 21. Specifications 519,620 and 550,316, [Group XXVI], are referred to.

Title: Improved method of forming ceramic bodies
IPC: B28B3/02
Filed: 1942-06-12
Abstract: 559,618. Moulding porcelain articles. SHEPHERD, G. R. (Westinghouse Electric International Co.). June 12, 1942, No. 8084. [Class 87 (ii)] Fine particles of a dampened porcelain batch are compressed in a mould, air being evacuated from the mould and the batch during compression, and the particles, during compression, move transversely relatively to one another. This transverse movement, which results in a dense product, may be obtained in two ways :- (1) By placing the porcelain batch in an uneven pile in the mould, and then densifying it with the fingers, or with a simple wooden form, around the edge of the die or around the location for a thickened portion of the article being moulded, such as the post b, Fig. 2, of a transformer tap changer. When the batch is compressed, the material moves with a lateral sliding action into the crevices of the dies. (2) By providing bores or recesses 124, Fig, 6, in the inner wall of the mould 126, and securing to the inner wall a resilient lining 122 of rubber &c. During compression of the porcelain batch in the mould, the lining gives at the bores, thus allowing a lateral sliding action between the particles of the batch. The dampened porcelain batch may be made by forming a slip containing kaolin, ball clay and water, the ball clay content being 10 per cent. or less, casting the slip in a plaster mould, allowing it to dry to 17.5 per cent. moisture, and disintegrating it. Alternatively, typical plastic vitreous insulator material may be dried to 17.5 per cent. moisture and then shredded or grated into small particles. Fig. 1 shows apparatus comprising an exhaust pipe 56 communicating with a bore which emerges at the upper face of the mould 42, inside the sealing ring 102. The upper die 84 is a loose fit in the housing 92, to allow of the exhaustion of air. Stops 104 on the casing limit the descent of the die. An ejecting-rod 66 passes through a chamber 74 having an outwardly-opening flap valve 78 and a sealed cleaning opening 82. Fig. 6 shows modified apparatus, in which the exhaust pipe 142 is connected to the housing 110. The article may be compressed two or more times.
