Title: Improvements relating to protective sleeves for torque-transmission shafts in agricultural machines
IPC: A01B71/08
Filed: 1967-08-02
Abstract: A non-rotary protective sleeve for universally jointed shafts of an agricultural machine, comprising at least two relatively movable telescopic tubes for enclosing the shafts, at least one of the tubes 1 having an enlarged, open-ended terminal member 2 for covering a shaft joint, is rotatably mounted on a cylinderical member 3 of the joint by bearing balls 5 running in a circumferential groove 4 in the member 3, the balls 5 being retained against radially outward displacement by an axially movable bearing ring 6 which is axially located in the member 2 either by resilient means or by positive locking means. As shown, a resilient annular fitting 7 connects the member 2 to the tube 1 and has tabs 71, 711 between which the bearing ring 6 and a guide ring 8 are held. To prevent their rotation, the tabs 71 engage recesses 6111 of lugs 61 on the ring 6, and a nose on the ring 7 engages one of four notches (11) in the guide ring 8. A retaining ring 9 has a lug 91 projecting through an opening 12 in the ring 7 for attachment to a conventional safety chain. A cage 10 guides the balls 5. To remove the sleeve, tabs 71 are raised, e.g. with a screwdriver, and the bearing ring 6 moved axially until the tabs 71 engage recesses 611 in the lugs 61 (Figs. 5, 6, not shown). The balls 5 can then move radially outwards from the groove 4, so that the sleeve can be slidden relative to the shaft. In a modification, the ring 7 is rigid and has withdrawable locking members to engage either side of the ring 6. Alternatively a separate rigid locking ring with withdrawable members may be used.

Title: Center support marine boiler with isolated reheater
IPC: F22B21/34
Filed: 1968-12-06
Abstract: In a vapour generator for a marine power plant having a generally rectangular setting with tubes for cooling its walls, a compartment 38 housing a reheater 14 and having burners 116 is located within the upper part of the setting and separated from the furnace chamber 34 with burners (78), Fig. 3 (not shown), and the convection section 36 housing a superheater 12 by a tubular gas impervious partition. The furnace chamber extends for the full height of the setting over part of the width and the partition extends rearwardlc from the front wall 48 of the setting to the boiler section 30. The partition is formed by the upper vertical portions of tubes 92 lining the lower part of the setting side wall 51 and tubes 108, Fig. 4, extending between the horizontal headers 64 and 94. The header 64, Fig. 5, communicates with the lower drum 42 and is attached to the front wall header 58. A diaphragm (65), Fig. 6 (not shown), isolates the rearward portion of the header 64, from which the tubes 108 extend, from the forward portion which is protected from the furnace gases by a portion 96, Fig. 5, of the tubes 92. The upper portions 72b of tubes 72, Fig. 2, lining the lower portion of the rear of the furnace chamber 34 are mutually spaced apart and screen the superheater 12 and reheater 14 from the radiant heat from the burners 78 and 116. The generator is vertically supported from the lower drum 42 of the boiler section 30 and the horizontal headers 58, 60 and 62 which are mounted at spaced points thereabout. The generator (11), Fig. 1 (not shown), supplies an ahead turbine (16) with high and low pressure stages, steam from the high pressure stage being reheated in the reheater (14) before being passed to the low pressure stage. When supplying an astern turbine (18) the operation of the burners 116 in the reheater compartment 38 is terminated.

Title: Installation for pulverizing and drying crude quarry products
IPC: C04B7/36
Filed: 1969-05-05
Abstract: A plant Fig. 1, for pulverizing and drying rough quarried products, particularly in the manufacture of cement, using hot gases from a kiln used to process the pulverized materials comprises a stone-breaker, e.g. a hammer mill 3, a centrifugal dynamic separator 9 which supplies granular material to a crusher, e.g. a ball mill 13 and filtering and separating equipment to separate pulverized material contained in a gas flow from the dynamic separator. This flow is produced by a fan 15. Gas is supplied via ducts 17, 21, 19 to the stone-breaker, the dynamic separator and the crusher in parallel, and from the stone-breaker and crusher to the dynamic separator via a duct 22. A single gas flow charged with pulverized materials is fed along a duct from the dynamic separator at 23 to the filtering and separating equipment. This comprises a precipitation tower 24, having a water atomiser, and an electrostatic filter 25. Fine materials are extracted and discharged via a conveyor 26. A fan 29, a duct 30 and a flow regulator 31 permit a variable proportion of the gas flow leaving the electrostatic filter 25 to be recycled to the dynamic separator 9. The temperature of the gas mixture and pulverized material is monitored by a thermal pick up, the signal controlling either an auxiliary heater 16 or the water supply to the mill 3 or the precipitation tower 24. The dynamic separator, Fig. 2, has a rotor 42 with a section 46 serving as a turbo-centrifuge, and a drying column 52 with a slatted grill 55. Material is introduced via a duct 41 and the heaviest components are hurled against the walls. Two gas flows (at 48 and 54) carry material upwards, and out via ducts 56, while the denser and now dry material falls into the duct 53.
Patent ES-383324-A1 (ES)
Title: Pump assembly
IPC: F04C15/06
Filed: 1970-09-02
Abstract: An improved pump assembly includes intake passage which conduct fluid from a reservoir assembly to radially opposite sides and opposite ends of a rotor assembly. To provide controlled reduction in velocity and corresponding increase in pressure as the fluid flows through intake passages toward the rotor assembly, the intake passages increase in cross sectional area in the direction of flow. A bypass valve directs a flow of fluid from the pump assembly to an auxiliary external system when a main external system is shut off. The rate of fluid flow to the auxiliary and main external systems is maintained at a predetermined maximum rate by a flow control valve assembly which diverts fluid from a discharge passage to the intake passages in response to a predetermined pressure drop as fluid flows through a nozzle at the predetermined maximum rate. When the pump assembly is to be used in different environments, the direction in which the pump assembly is adapted to be driven can be reversed by changing the orientation of the rotor assembly and end plates of the pump assembly. This adaptability of the pump assembly to different environments is enhanced by the reservoir assembly which can be rotated to any one of a plurality of positions relative to the pump assembly.

Title: Method of manufacturing a contact body
IPC: B28B1/52
Filed: 1975-04-08
Abstract: A method of manufacturing a contact body for at least one flowing medium is disclosed wherein layers of asbestos fibers are formed and arranged so that the layers bear against one another at mutually spaced positions to provide channels in the body extending from one end thereof to the other to allow the flowing medium to pass therethrough. The layers of the contact body are first treated by supplying to the layers at least one inorganic substance which produces a hydrated precipitate on the asbestos fibers of the layers. Thereafter the layers are heated to a temperature which is at least within a temperature range at which the hydrated precipitate releases its water of crystallization, but which temperature is below the sintering temperature for the substances remaining in the body. As a further step, at least one further substance is supplied to the contact body layers which restores the mechanical strength of the body lost by the transformation of the asbestos fibers during the heating step.
