Title: Variable pitch propeller

Filed: 1964-08-11
Abstract: 1,066,718. Variable-pitch propellers. G. W. KEAN, A. J. RONCARI, A. J. RONCARI, and R. A. RONCARI. Aug. 11, 1964, No. 32637/64. Heading B7V. A variable-pitch propeller, e.g. for an outboard drive, includes a hub (6) having blades 10 extending radially therefrom and rotatable thereon between positions of maximum -and minimum pitch, means for mounting the hub on a drive-shaft 49 for axial movement thereon, means biasing the blades towards a position of maximum pitch relative to said hub and means for varying the biasing force exerted by said biasing means responsive to resistance forces exerted upon said blades upon rotation of the propeller consistent with the driving torque applied to the drive-shaft. As shown, in Fig. 3a, racks 45 mounted on rack support 44 are biased by spring 42 to turn pinion portions 15 of gears 14 on the blades 10 so that the blades are biased to the maxinum pitch position. The bevelled portions 16 of the gears 14 are in engagement with a bevel gear 17 attached to a sleeve .32 which is axially slidable along a sleeve 31 pinned at (52) (Fig. 11, not shown) to drum shaft 49. Sleeves 31, 32 are coupled together at (18) (Figs. 13 and 14, not shown) in order that the hub 6 may be rotated and also to turn blades 10 to a fine pitch position. On starting, the blades are biased to the maximum pitch position which is fixed by lugs 23 engaging the end of slots (36) in collar (35) (Fig. 5, not shown). In this position, the water resistance to rotation is greatest so that torque applied to drive-shift 49 and transmitted through pin (52), sleeve 31, coupling (18) and bevel gear 17 to blades 10 overcomes the water resistance and also rotates the bevel gear 17 related to gears 14 and moves gear blades 10 to the fine pitch position. As the blades rotate towards minimum pitch positions, the pinion portions 15 which engage racks 45 likewise rotate and move the racks and support 44 axially inwardly to compress spring 42 against flange 40. With the pitch of the blades reduced, the water resistance is decreased and brought into balance with the opposing force of spring 42. When torque is transmitted to the drive-shaft 49 sufficient to completely overpower spring 42 and the blades are at the minimum pitch position a greatly increased thrust will be developed by the propeller. Before the boat responds however, the forward force thereof acts on the propeller assembly causing forward axial movement of hub 6 with respect to the drive-shaft 49. As the hub 6 is urged forward on the shaft, the parts carried thereby-the blades 10, racks 45 and the shaft 32 are also moved axially forward until there is full engagement of projections (24), (25) of coupling (18) (Figs. 13 and 14, not shown) which will further compress spring 42.

Title: Improvements in or relating to the storage of fresh fruit
IPC: A23B7/148
Filed: 1936-12-01
Abstract: 476,272. Preserving fruit. PIQUE, J. J. Dec. 1, 1936, No. 32918. [Class 49] In storing fresh fruit, the content of carbon dioxide and oxygen in the atmosphere of the storage chamber is adjusted at the outset, as soon as the fruit has been placed in the storage chamber and the latter closed, to give the atmosphere most suitable for the fruit being stored, and the atmosphere in the chamber is thereafter controlled to maintain the most suitable condition thereof by introducing oxygen and employing a liquor which absorbs carbon dioxide to absorb this gas therefrom. In the example given, the fruit is contained in boxes or trays 1 which are stacked on a slatted platform 2 in the storage chamber 3 which is heat-insulated and has an inner surface of metal or other gas-impervious material. A tubular cooler 4 and a fan 5 are disposed centrally in the chamber for cooling and circulating the atmosphere therein. Nitrogen and carbon dioxide are first supplied to the chamber from cylinders 5a, 6, air leaving through valve 8 which is closed when the atmosphere has the desired composition, e.g. for Cox's Orange Pippin apples, about 5 per cent carbon dioxide, and about 2À5 per cent oxygen and for Bramley's Seedlings about 8-10 per cent of carbon dioxide and about 13-11 per cent of oxygen, the remainder in each case being nitrogen, the storage temperature being 40‹ F. As the oxygen is absorbed by the fruit more is supplied from a cylinder 9 or by delivering air to the chamber by a pump 10 or through a valve 11 to the cooler 4. To absorb the carbon dioxide the atmosphere is withdrawn from the chamber 3 through a pipe 16 by a pump 15 which supplies it through a pipe 17, the lower end of which has perforations 18, to a vessel 12 which is packed with Raschig's rings and filled to the level of valve 24 with milk of lime. The treated atmosphere returns through pipe 19 and cooling coil 20 to the chamber. Water lost from chamber 12 is replaced from the storage tank 23a. When the milk of lime is spent, it is drained off through valve 25 and water is added to wash the rings and drained off, and a fresh charge of milk of lime made in tank 27 is fed by pump 28 to the vessel 12. The pump 12 may be controlled by a carbon dioxide and oxygen measuring apparatus 30. A pressure gauge 34 is provided. When choked the perforations 18 are cleared by closing valves 35, 36 in pipes 17, 19 and blowing air in through a valve 37, the air being released through a valve 38. Specification 172,673, [Class 49], is referred to.
