Title: Apparatus for and Methods of Making Bimodal Electrophotographic Copies
IPC: G03G21/00
Filed: 1981-01-06
Abstract: A bimodal electrophotographic apparatus and process incorporates capabilities for making both positive and reversal copies. One surface of a layer of a zinc oxide coated paper, is charged. The surface is then imagewise exposed. A charged toner is applied by a magnetic brush. In the reversal mode, the brush has a bias potential. A paper supporting shoe having an electrically insulated structure may be located beneath the coated paper, with the insulation in the area where it passes adjacent the magnetic brush so that no current can pass through the toner after it is deposited onto the coated paper. Preferably, a pair of fuser rollers are electrically insulated so that when they come in contact with the surface of the coated material, after the toner is deposited thereon, they do not dissipate the image-caused charge. The fusing rollers may also be given a bias corresponding to the bias on the toner, for the same reason.

Title: Space craft propelling apparatus
Inventor: WILKINSON JOHN
IPC: B64G1/40
Filed: 1983-02-24
Abstract: A propelling apparatus for a space craft comprises an upright electromagnetic solenoid (9) in high rotation with a tubular internal vertically vaned core, an extended internally vaned tubular driving shaft axially aligned above it, an inlet for magnetically responsive liquid pumped into the top of the motorized driving shaft in centrifugal downward progression which enters the larger diameter solenoid core with increasing angular velocity through a centrifugal constriction on core base, on emergence the liquid divides and impacts a circular walled confinement within a reaction absorption chamber.

Title: Modularized computer system
Inventor: AIREL DAVID L
IPC: G09G5/14
Filed: 1983-06-28
Abstract: A portable computer has a keyboard, 4 line by 80 character LC display, programmable disk-drive-like memory, EPROM, CPU, and a RAM. The 4 x 80 display replicates a 24 x 80 dedicated portion of the RAM to thereby provide a window into the RAM. Facility is provided to display the 24 x 80 RAM memory on a CRT display. The computer receives its operating instructions from its disk-like memory and EPROM into a RAM each time it is turned on. If the computer is plugged into an office station, it engages an office station interface unit which provides a port for each peripheral that the computer may engage. Each port has associated with it a PROM. Instructions on the PROM are paged in place of the RAM each time the computer is turned on and during the operation of any peripheral, to control initialization and operation of the peripheral. A power distribution control system senses the power level of the battery attached to the computer and shuts off the computer when power drops to too low a state. In turning OFF the computer, the system removes substantially all of the power consuming elements from the circuit, for battery protection (Figures 3,7, not shown). <IMAGE>
