Patent CA-2079051-A1 (CA)
Inventor: DECAP CAMILLE
IPC: B60P1/56
Filed: 1992-09-24
Abstract: A conventional bottom dump truck includes doors which in a closed position are suspended underneath the bottom opening of the hopper of the trailer. The doors are opened outwardly and upwardly by pivotal action about an upper suspension point of each of the doors. The amount of movement of the door is limited by an abutment member mounted upon a vertical flange on the outside surface of the hopper bottom. The abutment member includes an abutment plate extending outwardly from the flange together with a bracket which has a slot slidable along the length of the flange and locatable at different points along the length of the flange by a pin passing through openings in the bracket and one of a plurality of openings in the flange. The flange can be rotated about an axis longitudinal of the flange to move the abutment member out of the path of the abutment on the door and simultaneously to move a second abutment member into engagement with the door which is positioned at the maximum allowable opening of the door.

Title: Spray type retort sterilizer
Inventor: YAMAMOTO TUTOMU
IPC: A61L2/07
Filed: 1991-03-11
Abstract: This invention relates to a spray type retort sterilizer which performs various kinds of high-pressure sterilization of gas foods containing a lot of gas, transfusion soft pack for medicine, etc. and it object is to prevent the hot water drops spray on the object material for treatment (3) placed on the trays (2) disposed inside the tank (1) from instantly evaporating by boiling.      The technical construction of this invention is that it is provided with a tank (1) in which trays loaded with the object material to be treated are stacked in a plural number of stages, spray units (4) which emit hot water or cooling water on the object material (3) on the tray (2) in each stage inside the tank (1) and a circulation route (5) through which to blow the water accumulated at the bottom of the tank (1) in the form of mist from the spray units (4) again under pressure through a pump (6) and a heat exchanger (7) and is also provided inside the tank (1) with an internal pressure adjusting system composed of a pressurized air intake system (11) which introduces pressurized air into the retort and an exhaust system (12) which evacuates gas from inside the tank (1). In a retort sterilizer having a construction as described above, the internal pressure of the tank (1) can be set at a pressure at which the desired hot water drops are not instantly atomized by boiling with mutual operations of the pressurized air intake system (11) and the exhaust system (12), thus providing a unique effect of making it easy to provide a retort sterilizer of high practical value which can blow desired hot water drops exactly and uniformly against the object material in the tank (1) and equalize the temperature in the entire area of spraying to ensure a treatment of high efficiency.

Title: Method of making semiconductor components as well as a solar cell made therefrom
Inventor: SAFIR YAKOV
IPC: H01L31/0216
Filed: 1991-05-29
Abstract: Doped areas on semiconductor components are made by applying to a portion of the surface of a semiconductor substrate an oxide forming mask layer which contains dopant, said semiconductor substrate with the mask layer being heated to a temperature sufficient for diffusion of part of the dopant from the mask layer to the semiconductor substrate, where also undesirable auto-doping of the unprotected surfaces of the semiconductor substrate takes place during the doping process, for which reason the auto-doped areas of the semiconductor substrate are etched away by alkaline etching or plasma etching, said mask layer constituting a protective barrier for the doped areas below the mask layer. In the production of a solar cell with two doped areas of the P and N conductor types, respectively, the distance between the two doped areas may be used for adjusting the gradient of the dark current with a diode biassed in the blocking direction.

The spool (58) includes a head (122), a base (125), and a necked portion (127) extending between the head (122) and the base (125).  The dimensions of the head (122), base (125) and necked portion (127) allow the filter assembly (52) to be installed and removed over the head (122) and base (125).  The spool (58) is disposed in the brew chamber (45) with the head (122) controllably movable in the inlet (43) and the base (125) controllably movable in the outlet (41) for controllably opening and plugging the inlet (43) and outlet (41).  A port (176) is coupled to the flush water dispenser and extends through the exterior surface of the spool (58).     A discharge line (551 from the brew chamber (45) has a controllable discharge valve (55a) to direct flow from the brew chamber (45) through a dispensing line (55b), a waste line (55c), or to prevent flow through either line (55b,55c). Water may be controllably accumulated in the brew chamber (45) by controlling the discharge valve (55) to prevent flow through either line (55b,55c).  The discharge valve (55a) blocks the discharge line (55) to retain water in the brew chamber (45) to float spent brewing substance (53a) off of filter material (164) in the filter assembly (S2).

Abstract: Hollow tubing having a generally rectangular cross-section has a longitudinal ridge along a top and a corresponding longitudinal channel along a base. Pieces of tubing can be stacked on top of one another with the ridge of one piece of tubing engaged in the channel of another piece of tubing.  The truck or trailer has a peripheral frame and a first piece of tubing is welded to an edge of that frame with the ridge extending upward.  Caulking is then placed along the ridge and a second piece of tubing is placed on the first piece so that the ridge of the first piece is located within a channel of the second piece.  This method is repeated until a wall of desired size is constructed.  Pieces of tubing subsequent to the first piece, are not welded to one another.  When the wall is completed, U-shaped brackets are welded to each end.  No pre-existing supports, whether vertical or horizontal are required.  The tubing is extruded aluminum and presents smooth outer and inner surfaces upon completion.  Presently, aluminum boxes are constructed for trucks and trailers using aluminum flats or strapping that are welded or riveted to pre-existing vertical and/or horizontal supports.
