Abstract: ABSTRACT OF THE DISCLOSURE         A method of printing by electrolytic coagulation, using an improved colloid solution in association  with a  dyed colloid swelling  agent  which  permits  improved  dye transfer from dyed coagulated images to enable  very fast  and accurate  printing on ordinary  paper.    The  dyed  colloid  swelling agent is rapidly absorbed by the coagulated colloid for dye transfer  on any paper surface wetted   with a paper wetting agent which is a solvent of the colloid swelling agent.  The  colloid is of reliable uniform quality and performance and is used in combination with a salt or acid to render the solution conductive.  The  colloid is selected from  the  group  of  linear synthetic colloids of high molecular weight, including polyacrylic acid and polyacrylamide resin.  The swelling agent is selected from the group consisting of glycerol, sorbitol, ethylene glycol,  formamide  and  N-methyl pyrrolydone.          The paper  wetting agent is selected from the group consisting of methyl alcohol, ethyl alcohol, isopropyl alcohol, and acetone.

Title: Automatic polling sequence for modular computer  system with expansion bus

Abstract: Abstract of the Disclosure An initial polling sequence for configuring a modular computer system employing a system bus for interconnecting the CPU and various modules attached to the bus.  At the beginning of the polling sequence, a bus base address register in each module is preset to a port 0 address by the CPU.  A POLL signal is generated by the CPU and intercepted by the closest module, which responds by placing a module identification character on the data lines of the system bus.  The CPU receives the module identification character, stores this character in a table and issues a bus base address for that module.  Upon receipt of the bus base address, the module presently active in the polling sequence issues a POLL command to the next module on the system bus.          The poll sequence is repeated until all modules have been assigned and have received a bus base address.     25.1

Abstract: ABSTRACT OF THE DISCLOSURE A time-of-use watt-hour meter is provided with demand  profile  capability  that  defines  a  plurality  of survey periods and demand intervals.  During each survey period, electrical consumption is measured during a plural-ity of demand intervals.  The highest measured interval demand occurring during each survey period is saved and compared to  the highest interval demands for subsequent survey periods.  The five highest interval demands occur-ring during a billing period are saved for inspection by both the electric utility and the consumer.  The use of the survey  periods  and demand intervals has  the beneficial affect  of  avoiding  clusters  of  peak  periods  occurring during a single sustained period of high electrical con-sumption.  The results of the demand profile data compila-tion can be viewed  at the watt-hour meter or remotely.

Abstract: Abstract A  dry  bleaching  composition,  particularly useful for low temperature applications, is provided in which generation of hypochlorite by reaction between a peroxygen bleaching agent and a chloride salt is promoted by an aromatic diol or oxidized aromatic diol activator. Preferred  activators  are  in  ester  form  and  provide hypochlorite generation at levels of less than about 20 ppm for at least about the first two minutes following dissolution of the compositions in aqueous solution, but rising to effective bleaching levels within a reasonable time thereafter.  The initially low hypochlorite level assists in the functioning of laundry additives, such as fabric brighteners.

Abstract: ABSTRACT OF THE DISCLOSURE There is described a method of transmitting data on a communications network having first and second unidirectional oppositely directed buses and access units coupled between the buses.  The method includes the steps of arranging the data to be transmitted from the access units in data packets, and establishing a distributed queue in the network to control the order of data packet transmissions from said access units.  Preferably, the method includes determining according to destination upon which one of the buses a data packet is to be transmitted from one access unit.  A request flag is then transmitted on the second bus when the one access unit has a data packet for transmission on the first bus.  A request flag counter is incremented at the one access unit each time a request flag is detected by the one access unit on the second bus from access units upstream of the one access unit on the second bus.  The counter is decremented each time an empty data packet is detected by the one access unit on the first bus and the data packet is transmitted from the one access unit on the first bus in accordance with the count of said counter.

Abstract: "Radio Paging Device Having Circuitry for Rewriting a Stored Message with Error-free Characters"                 ABSTRACT OF THE DISCLOSURE A radio paging device is disclosed wherein characters of a received message signal are checked for error and stored into a first storage area.  Second storage areas store a plurality of different message signals received in succession prior to the reception of the message signal in the first storage area.  A control circuit compares error-free characters in the first storage area with positionally corresponding error-free characters in each of the second storage areas to detect a match or a mismatch therebetween.  If the mismatch is detected, all the characters of each of the second storage areas are shifted to the next storage area and all the characters of the first storage area written into the second storage area in which the most recent one of the different message signals was stored.  If there is a match between all the error-free characters of the first storage area and a given one of the second storage areas, characters of the given second storage area are rewritten with positionally corresponding error-free characters of the first storage area.  The rewritten message signal is then supplied from the given second storage area to the display.

When embodied in a data entry tablet, the invention provides signals representative of the positions of a stylus movable within the area of the tablet and comprising first and second photodetectors spaced along a base line by a predetermined distance, and means associated with each photodetector and operative to provide a movable narrow field of view for each photodetector. Means are provided for monitoring the angular position of each of the fields of view with respect to the base line and for providing a signal indication of the respective angular positions.  A stylus having a light emitter at the tip thereof is movable within the area of the tablet and provides light detectable by each of the photodetectors. Each of the photodetectors provides a respective signal when the field of view of the corresponding photodetector receives light from the emitter. Means are provided which are operative in response to the signal indication of the angular position of each of the movable means at which light from the emitter is respectively detected to provide a signal representing the position of the emitter within the area of the tablet.

Abstract: ABSTRACT OF THE PRESENT INVENTION      A communications medium for transmitting data between a plurality of peripheral devices and a host computer.  Only one device may talk on the bus at a time and only in response to a command from the host.  When a peripheral device needs to be serviced, it sends out a service request signal by holding the bus low after any command signal.  The device continues to request service until it receives a talk command from the host computer.  When more than one device are the same type (for example, two mice) are coupled to the bus, the host computer assigns new addresses to the devices.  Devices detect collisions by sensing a low signal on the bus when they attempt to send a "1".
