Abstract: 714,563. Doors for resisting fluid pressure. BLAW-KNOX CO. Nov. 25, 1952, No. 29829/52. Class 123(1) A closure for processing vessels, e.g. vulcanizers, comprises a frame 9, a door 2 fitting in an opening in the frame 9, a split locking ring 10 carried by the frame 9 and arranged on contraction to force the door 2 into tight contact with the frame 9, and a packing ring 27 for preventing leakage between the closed door 2 and frame 9. The ring 20, which floats in an annular groove 19 in the frame 9, is contracted by a jack 21, brackets 22 on which are connected, through slots 23 in the frame 9, with the ends 20a of the ring 20. On contraction, a bevel 25 on the ring 20, acting on a bevel 26 on the door 2, forces it against the frame 9, there being contacting bevelled surfaces 16, 17 on the door 2 and frame 9 respectively. The door 2 is suspended from a pivoted arm by a vertical spindle eccentrically mounted transversely of the arm, the door being vertically adjustable on the spindle, and the spindle being horizontally adjustable on the arm by rotating the eccentrically disposed bearing for the spindle. Hence the door 2 can be centred on the frame 9.

Title: Golf ball
IPC: A63B37/00
Filed: 1972-06-26
Abstract: 1402271 Golf balls UNIROYAL INC 26 June 1972 [25 June 1971] 29831/72 Heading A6D A golf ball is provided with dimples arranged to fall within a regular icosohedral lattice of equilateral spherical triangles nationally inscribed on the surface of the ball. In the embodiment (Fig I) the vertices of the (notional) spherical triangles are formed by pentagonal pyramidal dimples 16, and the sides 14 of the triangles (which are great circular arcs) are divided into five equal portions (see Fig 3). Lines are drawn parallel to the sides 14 to form a lattice of minor vertices, a hexagonal pyramidal dimple 11 being located at each end of those minor vertices. Thus 240 hexagonal dimples and 12 pentagonal dimples are present. The ball is preferably made in a mould of two hemispherical parts, each part being identical and being of the form shown in Fig 1 (i.e. having a central pentagonal dimple). The two halves of the mould must be displaced by 36 (clockwise or anticlockwise) with respect to a central axis perpendicular to Fig 1 if a true icosohedral lattice is to be produced, but errors within working tolerance are allowable. The ball may be of conventional wound core construction or be of solid material. The cover may be of balata or of an ionic copolymer of ethylene (96.5 mole %) and methacrylic acid (3.5 mole %) containing sodium or zinc ions. The core (if present) may be of cis polybutadiene or mixture of cis polybutadiene and rubber (natural or synthetic cis polyisoprene), or of metal or synthetic plastics. Preferred dimensions and alternative materials are given in the specification. In alternative constructions some or all of the dimples may be part arcuate or part spherical in shape (both in depth and/or circumference) or may be of elliptical curvature. Particular examples have either the pentagonal or the hexagonal dimples replaced by hemispherical dimples.

Abstract: 814,607. Seats. LORENZ, A. Oct. 25, 1955 [Nov. 5, 1954], No. 30459/55. Class 52(2) The Specification describes a reclining chair including a seat, a back-rest and a leg-rest and various lazy-tong mechanisms for projecting the leg-rest as the backrest is tilted to reclining position. As shown in Fig. 1, a back-rest 16 and seat 22 are pivoted at 18 to a base 10 and the legrest 58 is carried by a pivot 62 and a pivoted link 66 on the front of a lazy-tong linkage 40, 44, 30, 32. The inner end of link 40 is pivoted at 42 to the seat and the inner end of link 44 is pivoted to the foot of a link 48 pivoted at 50 to the base 10. As the back-rest is rocked rearwards, a downward extension 20 thereof moves link 52 forwards to swing link 48 about pivot 50. This causes the lazy-tong linkage to raise the seat and extend the leg-rest. 'In a modification, Fig. 3 (not shown), the back-rest and seat are formed as an integral unit. In a further modification, Fig. 4 (not shown), the back-rest and seat, again formed as an integral unit, have the lowest part of the downward extension pivoted to the base and the link 48 is formed as a bell crank, the upper arm being linked to the upper part of the extension. 'In a further modification, Fig. 2, link 144 of the lazy-tong linkage is pivoted at 157 to the foot of extension 120 and is constrained to move in the desired path by a link 148 pivoted to the base at 150. Stops may be provided to limit the pivoting in the sitting and reclining positions, and means may be provided for locking the parts in adjusted position.

The clamping means comprises two plates 42 which when drawn together by means of screw 48 and nut 50 press opposite portions of the hose into sealing engagement with the web 32 and wrap the hose tightly about the cylindrical portions 30. The passages 40 are screw threaded so that a source of fluid pressure may be affixed in communication with the hose. As shown one passage 40 is closed by a screw 52. Sealing rings may be provided in grooves formed in the portions 30. In another embodiment the nipple comprises a single cylindrical portion defining the passage and having a planar portion extending radially outwardly therefrom. The hose is pressed by clamping means similar to that shown in Fig. 1 on to the planar portion. As shown in Fig. 6 the nipple is provided with a chamber 74 having threaded bosses 76 axially disposed at right angles to one another. In a further embodiment Fig. 12 the nipple having a threaded bore 92 therethrough comprises a cylindrical neck 84 provided with serrations 94 and formed with a flange 86, and an elongated rectangular portion 88. The hose is clamped on the neck 84 by a clamp band.
