Title: A new or improved method of mounting a wheel or the like on a shaft
Inventor: ORWIN OLAF JOHN BARCLAY
IPC: F16H57/00
Filed: 1960-10-10
Abstract: 916,707. Jointing by forging. FISHER & LUDLOW Ltd. Nov. 17, 1961 [Oct. 10, 1960], No. 34592/60. Class 83 (4). A wheel or disc 11 having a central hub 17 and thinner web 15 is secured to a shaft 10 by slipping the wheel over the shaft and applying axial pressure to the wheel to contract the bore of the hub into tight engagement with the shaft. The steel wheel may have on its web annular projections 18, initially of " D " or triangular section, Fig. 2 (not shown) which are engaged and compressed by oppositely acting annular press tools 19. This causes thickening of the hub with a reduction in its bore and an increase in the overall wheel diameter. A number of circumferentially spaced longitudinal grooves 21, Fig. 1 (not shown), may be provided in the hub bore to facilitate the contraction. In another embodiment, Figs. 5, 6 (not shown), the axial pressure is applied directly to the hub.

Patent GB-737446-A (GB)
Title: Improvements in or relating to quick cooking rice and method of preparation thereof
IPC: A23L7/196
Filed: 1951-02-08
Abstract: In a process of preparing quick-cooking rice, hulled rice grains are steamed for a period of 30 seconds to 15 minutes and thereafter dried to a stable moisture content to alter the structure of the grains so that upon subsequent cooking the rice will absorb water rapidly so that the cooking time is reduced. The hulled grains may be soaked to increase the moisture content to 25-30 per cent and then steamed for a period of 30 seconds to 5 minutes.  Steaming may be carried out in a conventional manner, e.g. by an autoclave, a rotary cooker, preferably in an apparatus providing for the rapid passage of steam through the grain, e.g. by passing the rice through a cylindrical cooker in the centre of which is a perforated steam line through which steam under e.g. 50-100 pounds pressure is ejected at such a rate that even though it is vented from the column a pressure of about 5-10 pounds is maintained within the column.  Drying may be effected by spreading the rice in thin layers for a period of about two days or by blowing air across or through the layers for 12 to 24 hours or in a forced draught drier for about 30 minutes the optimum drying temperature being about 140 DEG  F. and the grain being reduced to a moisture content of 10-14 per cent.  In an example 100 pounds of white rice with a moisture content of about 14 per cent is placed in a 100-gallon vessel together with about 60 gallons of water and allowed to soak for 30 minutes when it is removed and drained and transferred to an 80-gallon autoclave and treated with steam at 8 pounds pressure for 5 minutes after which the grains are removed and dried in any conventional manner to a moisture content of 10 to 14 per cent, e.g. in a forced draught hot-air drier using air at 140 DEG F., the drying being effected in about 30 minutes after which the product is packaged.

Abstract: 1,092,096. Sail boom. M. S. GIBB Ltd. Aug. 24, 1964 [Sept. 11, 1963], No. 35851/63. Heading B7V. [Also in Division F2] A generally cylindrical body 1 to be attached to the end of a sail boom, e.g. by means of a rivet passing through holes 4, has secured to it, by a pivot pin 10, a hook 7 normally closed, as shown, against the body 1 by a spring 15 to retain an eye on a mast or sail. By pulling the boom to overcome the force of the spring, when the eye is nearest the hook nose 16, the hook is opened to the position shown in ghost lines to release the boom end. Alternatively, a lanyard attached in a hole 18 on the U-shaped hook member 7 may be pulled to open the hook. The hollow body 1 is somewhat flattened at its hookbearing end to form a slot in which the hook 7 is pivoted and the ends of 11, 12 of the slot project to form therebetween the bight for receiving the eye. The top end 11 is divided by a further slot 13 to permit the hook 7 to move to the open position as indicated. The end 12 is slightly notched to receive the arm 8 of the hook and the hook nose 16 extends beyond this to facilitate hooking of the eye. When the eye is nearest the top end 11 of the slot, a pull along the boom does not open the hook but tends to keep it closed.
