Title: Electronic data display card
IPC: G06K19/077
Filed: 1979-05-01
Abstract: An electronic data display card is a hand-holdable electronic card that enables its user to store information in a visual form which can be "read" easily by a person or a machine. The card is fundamentally different in idea from the conventional punch-card which requires a whole column to record a single character. The card has a complex multi-line/column grid of character spaces each of which spaces is able to visually display characters entered by a key section of the card. The user is able to read the characters displayed on the card because they look like uniform letters and numbers, unlike the punch- card which uses holes. The cards are versatile and flexible in use, they can be carried around (eg. in warehouses, hospitals, offices) and they can be "batch read" by machine. <IMAGE>

Patent GB-2037039-A (GB)
Title: Cache memory system
IPC: G06F12/08
Filed: 1979-11-05
Abstract: Cache store has a plurality, eg 8, levels each with an address source selection switch coupled between a plurality of address sources a and a respective address register. The cache cycle is split into two halves. In the first, in response to two sets of level signals from respective sources, one of the selection switches connects a memory data write address from one source to the appropriate address register while the remaining switches connect a next instruction address to the remaining address registers provided no level conflict arises. A comparator checks the level signals for conflict and delays the instruction access if conflict arises. Where no conflict arises both accesses are performed simultaneously. In the second half of the cycle CPU read and write operations are normally performed. However the second half of the cycle may be used to perform a CPU read operation and a memory data write operation simultaneously by using one selection switch to feed the write memory data address to one address register and the CPU address to the remaining address register. Suitably organised cache directories are described.

Patent GB-2088076-A (GB)
Title: Electrophotographic Developing and Transfer Process
IPC: G03G9/083
Filed: 1981-10-07
Abstract: In an electrophotographic process a magnetic brush development method employs a developer having two types of particles. The particles of one type have a volume resistivity of not less than 10<13> OMEGA cm, and the particles of the other type have a volume resistivity of not more than 10<10> OMEGA cm. The volume resistivity of this developer will change significantly depending upon the intensity of electric field applied thereto. Thus during development of a latent image on an electrostatic image bearing photo-conductor the developer is made to have a relatively low resistivity while during the transfer of the developed image to a copy sheet the developer is made to have a relatively high volume resistivity. Residual developer recovered from the photoconductor may be returned to the developing station where particles of one or other of the two types are added to maintain the ratio of the two types of particles at a predetermined level see claims 5 and 6.
