Title: Filtration removal of suspended solids from liquid - using particulate polyurethane filter bed regenerated by agitating with liquid to remove deposited solids
IPC: C02F/
Filed: 1979-04-20
Granted: 1986-02-10
Abstract: In the removal of suspended solids from a liquid by (a) flowing the liquid through a filter bed of discontinuous polyurethane particles in a filtration vessel and discharging solids depleted liquid from the vessel, the filter bed being at least partially loaded with deposited solids, (b) terminating the liquid flow and (c) renewing the filter bed by removing the deposited solids, the improvement comprises that the regeneration step (c) is carried out by adding >=1 bed volume of regeneration liquid (I) to the vessel and mechanically mixing the filter bed in (I) and hold-up liquid resulting from termination of liq. flow to disengage the deposited solids from the polyurethane particles. Solids-enriched liquid is then discharged from the filtration vessel. Only a very low volume of (I) is required. Liquid to be treated may be effluent contg. 40-60 ppm suspended solids, river water, water for use in boilers, or a stream from an algae pond (oxidation ditch).

Title: Eccentric mechanism for crank machines
Inventor: CESARINO MOLARO
IPC: F16H/
Filed: 1989-09-06
Granted: 1992-07-03
Abstract: The eccentric mechanism, in place of piston and rod, for crank machines, pumps and piston motors, transforms rotatory motion into alternating linear motion and vice versa, allowing constant alignment of the slide without any lateral force on the guide. It is constituted by a ring having outer circumference equal to the slider or piston coupling ring and internal through holes, off-centred in equal measure to the distance between the centre of the shaft (goose neck) and the centre of its crank, and diameter equal to the diameter of the crank itself. It may operate as a sleeve bearing and is fitted with a gear mechanism centred on the internal through hole. Such gear mechanism, connected either indirectly or directly to an appropriate gear mechanism fixed on the frame, allows the transmission of the motion and its synchronization, in opposite rotation, to the shaft with the crank.

Title: Device that makes it possible to mine a bank of layers of loose earth (gravel, mud, sand, peat etc.), even deep layers, to a selected size whilst leaving the undesired part in situ.
Inventor: SILVIA ANSELMI
IPC: E21C/
Filed: 1989-08-02
Granted: 1993-06-05
Abstract: This invention is for a device that makes it possible to mine a bank of layers of loose earth (gravel, mud, sand, peat etc.), even deep layers, to a selected size whilst leaving the undesired part in situ. It consists of a complex made with a suction tube in which the mobility of the material to be sucked up is secured by a fluid under adjustable pressure and speed, carried by a send tube fed from the first. A grill with different diameter holes is applied to the feed that fits the maximum dimensions of the material to be extracted. The tubes are activated by adequate sized pumps for the quality and quantity of material to be extracted. The device feed can be connected, at a pre-arranged depth, to the layer of material in question as well as inside or under the bank. This distinguishes the machine in the present invention from similar apparatus that are built to work higher up between the fluid and the solid.
Patent MX-167603-B (MX)
Inventor: LAROCHE E ALLEN JR
IPC: C04B35/65
Filed: 1988-01-07
Abstract: A method of producing shaped, self-supporting ceramic bodies includes preparing a mold by applying a permeable, conformable material (5) to a shape-defining surface (3) of an expendable pattern (2). The permeable, conformable material, when set or stable, provides a mold with a shaped surface which is defined by, and is therefore substantially congruent to, the shape-defining surface. Upon heating, the material of the expendable pattern (2) combusts or volatilizes and thus establishes the shaped cavity mold. A molten parent metal (1) is then vaporized with a vapor-phase oxidant in such a manner as to form a ceramic body which grows into the mold cavity, and is shaped by it. The ceramic body is recovered from the mold having a shaped surface replicating the shape-defining surface (3) of the expendable pattern (2).

Abstract: 1,164,226. Change-speed control. LINE A.G. 1 Nov., 1967 [24 Feb., 1967], No. 49610/67. Heading F2D. In the control of a vehicle, e.g. stacker or shovel loader, infinitely variable-speed gear, mechanical or hydraulic, of the type having two pedals 1, 2 for forward and reverse, and in which depression of one pedal raises the other, a third pedal 9 having a cross-member 8 with two stop members 10, 11 for engaging pedals 1 and 2 is also provided so that, on depressing pedal 9, whichever pedal 1, 2 had been depressed previously, pedals 1 and 2 are brought back to their central position neutralizing the gear, and facilitating engine braking. As shown, for an hydraulic gear, pedals 1 and 2 cut through bevel gears 3, 5 on a bevel gear 4 carrying a lever 12 which positions a pair of pistons 13 of a follow-up servo-system to adjust the gear. The pedal 9 may also adjust the speed of the engine; it may be connected to the ignition to stop the engine when the gear is neutralized; it may apply friction brakes to the vehicle wheels; and it may control the main clutch. Additional independent controls may be provided for engine speed and brake application. In Figs. 2, 3 (not shown) the third pedal (19) is adapted to apply a friction brake when excess pressure is applied to the pedal after normal pressure to neutralize the gear. The pedal comprises a crank lever pivoted between a pair of levers (34) carrying the cross-member 20 and its stops, and fast with a sleeve (25), a tension spring (37) connecting the pedal and the sleeve and a pair of stops being provided on the levers and pedal so that the pedal is aligned with the levers during normal operation. On applying excess pressure to the pedal, the crank lever pivots relative to the levers (34) against the action of the spring (37) to act through link work (41-46) to apply a friction brake. The forward and reverse pedals (21), (22) are also mounted on sleeves (23), (24) on opposite sides of sleeve (25) and interconnected by a lever (29) pivoted at its centre about a horizontal pin.

Abstract: A method is provided of producing a self-supporting ceramic composite structure having one or more encasement members (14), such as an encasing stell sleeve, joined to it by growth of the ceramic material to engagement surface(s) of the encasement member(s) (14). A parent metal is contacted with a body of filler (38) which is encased by the encasement mmber(s) (14). The resulting assembly is heated to melt and oxidize the parent metal, e.g., aluminum, to form a polycrystalline material comprising an oxidation reaction product which grows through the body of filler (38) and stops at the engagement surface(s) of the encasement member(s) (14) which thereby determines the surface geometry of the grown ceramic matrix. Upon cooling, the encasement member(s) (14) is shrinkfitted about the ceramic composite body. The invention also provides the resultant articles, for example, a ceramic composite body having a stainless steel member affixed thereto.
