Inventor: HORSLEY ERIK R
IPC: G06T3/40
Filed: 1993-03-05
Abstract: SYSTEM AND METHOD FOR DECOUPLING GRAPHIC COMMANDS FROM            DISPLAY RESOLUTION                          Abstract of the Disclosure A method and system to scale a graphics image from one graphics display resolution to a different graphics display resolution without the need for creating an entire new set of graphics commands. The present invention allows the non-integer scaling of a graphics image and creates an array of virtual pixels that control intensity of the actual pixels within the graphics memory and keep track of the source of intensity contribution for each actual pixel if scaled graphics images overlap an actual pixel. If one of the multiple sources of intensity for a given actual pixel is subsequently erased, the contribution information allows the actual pixel to be erased in a manner that accounts for the direction of the contribution as well as the actual intensity contribution.

Title: Solar powered emergency light
Inventor: MCDOUGALL ROBERT D
IPC: H02J9/00
Filed: 1993-08-25
Abstract: ABSTRACT    In a device for supplying emergency back-up lighting in commercial buildings and apartment buildings, it is known that the device operates from standard 110vac power which powers a battery charger and control unit within the unit.    In this invention the 110vac power supply has been eliminated.  Thus making the unit fully independent from external wiring.  In this invention solar cells are installed to operate the battery charger and control circuits.  This makes the new emergency lighting unit less costly to install due to the elemination of costly wiring.  Also the unit can be installed virtually anywhere, where as wiring to the conventional units would be almost impossible to do.

Title: Overload protection for switching transistor
Inventor: ANDERSON GARRY J
IPC: H03K17/08
Filed: 1993-10-20
Abstract: ABSTRACT OF THE DISCLOSURE An apparatus and method inhibit failure of a transistor, such as a switching transistor, due to short circuiting of a load connected thereto. Sensing is doneperiodically for short circuits of the load and a signal to the controlling element of the transistor is curtailed when a short circuit is sensed. Current through the transistor is limited sufficiently to prevent failure of the transistor between the periodic sensing for short circuits. The periodic sensing may be done by a digital processor. The limitation of current through the transistor may be accomplished by a second transistor connected to the base of the output transistor which you switched on to starve current directed flowing in the controlling element of the transistor when the current through the transistor is at least as great as a pre-set amount. Alternatively, where a FET is used as the switching transistor, the limitation of current may be accomplished by limiting the voltage applied to the gate terminal.

Title: Collapsible auger conveyor hopper bottom
Inventor: SCARROW DENNIS A
IPC: B65G33/24
Filed: 1994-01-07
Abstract: A collapsible hopper is used with a conveyor, for example a grain auger. The hopper is fastened onto the bottom end of the auger to surround the inlet. It has a flaccid side wall that is normally supported in a raised condition by a top, rigid hoop connected to the hopper base by a pair of springs. The springs allow the hoop to be deflected downwardly when engaged by another object, for example a truck box when it is dumping into the hopper. An over-centre linkage allows the springs to be released so that the flaccid hopper wall can collapse, allowing insertion of the hopper in this collapsed state into a position where there is insufficient clearance to insert the fully-raised hopper.

Abstract: Abstract of the Disclosure Methods are described for the removal of core particles,  fiber bundles  and  fines  from a  fibrous starting material obtained from hollow stalk plants such as kenaf, by field drying,  chopping and coarse comminution of the plant stalks and subsequent summary removal of core particles.  The material is pulped in hot water, and fine, lightweight fibers, other fines and residual core particles are separated from this first pulp.  A fibrous pulp is recovered wherein the fibers include less than 10%, preferably less than 5 % by weight of non-fibrous materials.      The separation of unwanted constituents may also be achieved by air classifying the plant material pre-treated as above,  in a special,  vertical multistage wind sifter.      The fibers which are obtained in a substantially uncontaminated state are useful as the sole fiber com-ponent or as reinforcing fibers in sheet materials such as mulch sheets, paper, cardboard, construction panels and packaging materials, etc.      (Fig. 1)
