Patent CA-1302456-C (CA)
Title: Convertible boat and vehicle trailer
Inventor: DANIELS LEWIS D
IPC: B60P3/10
Filed: 1988-11-10
Granted: 1992-06-02
Abstract: Abstract A trailer capable of carrying a boat and vehicle in a dual load mode of operation wherein the boat is mounted rearwardly of the vehicle in an inclined position with the bow of  the  boat  above portions  of  the  vehicle  being carried.   The trailer is also convertible into a single load mode of operation wherein the boat is carried low in a conventional orientation by lowering a supporting boat carriage into a collapsed position near the frame of the trailer.   The trailer is provided with a boat carriage which  is  connected  to  the  frame  of  the  trailer  and supported by a lifting mechanism which causes the boat carriage and any supported boat to shift rearwardly when they  are  moved  from the  collapsed  position into  the extended  raised  position.     This  rearward  movement automatically shifts the weight of the boat carriage and any supported boat rearwardly to counteract the loading associated with a vehicle  on forward portions  of the trailer. When used with boats and vehicles of normal sizes and weights the trailer automatically maintains the center of  gravity of the  trailer within an acceptable range whether used in the single load or dual load modes of operation, and without adjustment.

Title: Memory controller as for a video signal processor
Inventor: SPRAGUE DAVID L
IPC: H04N7/24
Filed: 1988-11-10
Granted: 1993-06-22
Abstract: RCA 84,943 Abstract A video signal processing system includes a memory for holding digital data, input and output channel circuitry for reading data from and writing data to the memory and processing circuits for processing data read from the memory to produce data to be written to the memory. Each of the input and output channels produces two types of memory request signals, a normal request signal and an urgent request signal. The normal request signal is produced to gain access to the data in the memory for normal read and write operations. The urgent request signal is produced to access the memory when the processing circuitry is in a paused state waiting either to obtain data from the input channel or to provide data to the output channel. The normal read and write request signals are handled with substantially equal priority by first scheduling circuitry. The urgent request signals are handled by second scheduling circuits according to a fixed priority scheme. The use of the second scheduling circuitry disables the first scheduling circuitry.
