Title: Liquid crystal detergent composition
Inventor: DURBUT PATRICK J
IPC: C11D3/20
Filed: 1990-09-21
Abstract: A liquid detergent composition which is in liquid crystal form comprises a synthetic organic surface active agent, as the detergent component, which preferably includes one or more nonionic detergents of the ethoxylated higher fatty alcohol type, and a lesser proportion of anionic or cationic surfactant, such as sodium dialkyl sulfosuccinate or dicoco dimethyl ammonium chloride, a cosurfactant, such as tripropylene glycol butyl ether, a solvent for the soil, such as an isoparaffin of 9 to 11 carbon atoms or. methyl cocoate (ester of methyl alcohol and coco acids) and water, with the water usually being the major component. Such compositions are useful for cold or room temperature cleaning of lipophilic soils, such as animal fats, from hard surfaces and from fabrics, and may be used as pre-treatments to loosen such soils from substrates to facilitate easier cleaning of dishes and laundry with conventional or the invented detergent compositions.      The invention also relates to concentrated versions of the compositions, which are not in liquid crystal state but which upon dilution with water are converted to such state.      Also within the invention are processes for pre-treating and cleaning materials soiled with lipophilic soils, using the invented liquid crystal detergent compositions. Additional processes of the invention are those in which liquid crystal detergent compositions are made by diluting concentrated compositions with water, and those in which lipophilic materials convert liquid crystal detergent compositions to microemulsion form, which latter processes occur during pre-spotting and cleaning applications when the liquid crystal detergent compo-sition contacts the oily soil on surfaces being treated.

Title: Atm cell multiplexing device capable of reducing an accessing speed to a fifo memory thereof
Inventor: KURANO TAKATOSHI
IPC: H04L12/54
Filed: 1992-03-27
Abstract: On time division multiplexing first through N-th input signals, each having a bit rate V to represent successive ATM cells, a multiplexing section (12, 13') multiplexes the first through the N-th input signals and a dummy input signal into a time division multiplexed signal having another bit rate V x (N+l) and comprising first through N-th multiplexed cells and a dummy multiplexed cell.  The first through the N-th and the dummy multiplexed cells are derived from the first through the N-th and the dummy input signals, respectively.  A controller (16') successively writes valid cells of the first through the N-th multiplexed cells in an FIFO memory (15) as written cells at a writing rate equal to the bit rate V x (N+l) for a writing time interval defined by the first through the N-th multiplexed cells and reads the written cells from the FIFO memory in a first-in first-out order as a read-out signal at a reading rate equal to the bit rate V x (N+l) for a reading time interval defined by the dummy multiplexed cell.  A converter (17) converts the read-out signal into a multiplexed output signal having the bit rate V.

Patent CA-2067560-A1 (CA)
Inventor: COTSONAS GEORGE P
IPC: H04W72/04
Filed: 1992-04-29
Abstract: A cordless telephone public base unit employed in a public telephone system in close proximity with other public base units effectively avoids contention with these other base units for access to a cordless telephone handset unit generating a service request. Contention between the public base unit and the other public base units is resolved by assigning a specific one of a plurality of times during which the base unit may respond to the service  request from the handset  unit. The time in which  the base unit responds to  the service request  may advantageously be determined by a randomly generated number, the received signal strength of the service request or a combination of these two parameters. Once access to the handset unit is acquired by a base unit and communications  between these two units is established on a communications channel, all other handset units and base units are prevented from interfering with the communications between these two units.

Title: Fault tolerant processing section with dynamically reconfigurable voting
Inventor: CHEUNG DOUGLAS D
IPC: G06F11/16
Filed: 1992-05-05
Abstract: Abstract of the Disclosure A fault-tolerant digital data processor includes three identical logic CPU boards connected to a voting bus and a system bus.  The three boards are initially designated as a master board, a slave board 0 and a slave board 1.  The master board drives the system bus and the two slave boards serve as backups in case the master breaks.  The master board issues signals, at different instances with the aid of multiplexing, to the slave boards.  On the slave boards, corresponding signals are compared and the result is broadcast to all three boards.  When all three boards are compared equal, the master board remains as master.  If there is a miscompare between one slave board and the master but not between the other slave board and the master, the master board remains master, and the slave board with which the miscompare occurred will be disabled after another miscompare.  If a miscompare occurs between the master board and both slave boards, a re-execution of the previous cycle occurs.  After a master board failure is confirmed, a slave board becomes a master board, and if there is another comparison failure the former master board is disabled.

Title: High efficiency process for producing alumina and apparatus therefor
Inventor: FULFORD GEORGE DENNISON
IPC: C01F7/445
Filed: 1990-11-23
Abstract: A process for producing alumina is described in which the efficiency of calcination is greatly improved by utilizing a total heat exchange system in which alumina hydrate is heated stepwise in a plurality of heat exchange stages to sequentially higher temperatures approaching calcining temperatures and is then fed to a calciner for final conversion to alumina, and the calcined alumina is cooled in a plurality of heat exchange stages, with sensible heat being transferred from the calcined alumina cooling stages to the alumina hydrate heating stages at a temperature in each stage only slightly higher than the temperature of a heating stage or at which the heat is consumed in that stage. Further efficiency in the system may be obtained by predrying the alumina hydrate to remove superficial moisture using air from the system.  Furthermore, exhaust gases from the calciner may be used to preheat combustion and fluidizing air for the calciner.
