Filed: 1990-01-10
Granted: 1997-04-01
Abstract: There is provided a totally enclosed electric motor which is effectively cooled by means of an internal ventilation system and an external ventilation system.  The internal ventilation system includes an internal fan driven by the rotor which forces internal ventilating air into and along an annular series of longitudinal internal ducts arranged adjacent to the internal cylindrical wall supporting the stator.  The internal ventilating air leaving the internal ducts enters a brush compartment where the air is directed axially over the commutator and through the stator-rotor arrangement and back to the internal fan. The external ventilation system includes an external fan driven by the rotor which forces external ventilating air from the atmosphere into and along an annular series of longitudinal external ducts arranged radially outwardly from the series of internal ducts and into exhaust compartments at the far axial end of the motor.

Title: Retractable boom stop
Inventor: ASCHE JAMES E
IPC: E02F3/38
Filed: 1990-09-10
Granted: 2001-05-15
Abstract: A retractable boom stop includes a channel shaped stop member mounted for pivotal and rectilinear movement relative to the boom arm of a skid steer vehicle. The stop member is movable between an inoperative position adjacent the boom arm and an operative position interposed between the boom arm and lift cylinder. In the operative position the stop member prevents an extensible rod of the lift cylinder from retracting to lower the boom arm.

Title: Controlled deflection roll
Inventor: BIONDETTI MARIO
IPC: D21G1/02
Filed: 1991-03-20
Granted: 2000-07-18
Abstract: In a controlled deflection roll comprising a roll shell rotatable about a stationary support and braced or supported by support elements at the stationary support, a rotational moment is intentionally exerted at the opposite ends of the roll shell by force-exerting elements. These force-exerting elements extend in axial direction of the controlled deflection roll but are offset in spaced relation with respect to the lengthwise axis of the controlled deflection roll. These force-exerting elements operate in pairs in opposite directions with respect to one another. A lever arm is formed by the distance or spacing between the force-exerting elements and such lever arm exerts a greater rotational moment in the presence of modest space requirements and without deformation of the roll shell.

Title: Method and a system for recycling waste materials including plastics materials
Inventor: STROPPIANA FERNANDO
IPC: B29B13/10
Filed: 1992-08-04
Granted: 2001-01-23
Abstract: A method and system for recycling waste materials enables the treatment of masses of waste including thermosetting plastics materials, high-melting thermoplastics materials, aluminium, wood, paper, fabrics, etc. The mass of waste is first subjected to a grinding process, preferably in two stages, to reduce it to a maximum particle size of the order of 10 mm.      The granular material thus produced undergoes a heating and mixing process and is then reduced to sheet or strip form and simultaneously cooled in order to undergo a scraping or shaving process which leads to the formation of a mass substantially comparable to a powder with a particle size of between 50 and 1000 microns, including a certain quantity of fibres. The shavings produced can be mixed with a better-quality plastics material, at least some of which may be produced from fairly large articles made of plastics materials which are first separated from the mass to be treated and ground separately, to produce a recycled plastics material in which the fraction of thermosetting materials, high-melting thermoplastics, aluminium, etc. constitute a filler and a fibrous reinforcing structure.

Abstract: IMPROVED METHOD AND APPARATUS FOR DISPENSING RINSE WATER        ADDITIVE IN AN AUTOMATIC WASHING MACHINE                    RICHARD M. BAGINSKI JEROME P. CAPPEL GARY E. McKIBBEN               ABSTRACT OF THE DISCLOSURE An improved method and apparatus for accurately measuring and  dispensing  a  rinse  water  additive  in  an  automatic  washing machine.   In  a  particularly  preferred  embodiment,  a  method  is provided for accurately measuring a relatively small volume of fluid product by forming  an  annular  column within the  dispenser.   The annular column extends at least to approximately the desired fill level for the additive so that the relatively small amount of fluid product causes a substantial change in the fluid's vertical position within the dispenser.  This is preferably accomplished by providing a dispenser having an internal pushup in its base, the pushup extending at  least  to  approximately  the  desired  fill  level  within  the dispenser.  An improved sealing means is also provided for the valve used to close the filling and dispensing aperture in dispenser body during the wash cycle.  Flexible securement means are used to secure a recessed valve means to the dispenser to minimize the chances of premature opening during the wash cycle.  Each of these improvements helps to insure that the correct amount of additive will be added to the dispenser and that substantially all of additive initially added to the dispenser will  be present when the valve is opened by the centrifugal force of the spin cycle so that all of the material can be effectively utilized during the rinse cycle.
