Granted: 1994-07-05
Abstract: ABSTRACT OF THE DISCLOSURE    A memory cartridge comprises a case, and a printed circuit board housed in the case is connected to a data processing unit including a microprocessor when the memory cartridge is loaded therein.  A memory cooperating with the data processing unit is installed on the printed circuit board, and a memory area of the memory is divided into a plurality of banks.  A multi-memory controller installed on the printed circuit board includes a plurality of registers into which data representing bank change-over conditions given from the microprocessor are loaded.  An address for changing-over the memory bank is outputted in response to the content of at least one of a plurality of registers.  Thus, by changing the above-described data, the microprocessor can specify an arbitrary bank at an arbitrary timing and utilize that bank.

Title: Conveyor assembly
Inventor: SJOSTRAND UNO
IPC: B65G21/22
Filed: 1988-01-05
Granted: 1991-06-11
Abstract: ABSTRACT     Conveyor assemblies which by means of an endless chain move foodstuff packages between different processing machines are customary  in  e.g.  the  dairy  industry.  Up to  now  the conveyor assembly generally was "tailor-made" for each dairy, which entails unnecessary cost and other difficulties.  In accordance with the present  invention  a conveyor  assembly  of  a  modular design is proposed which make it easily assembly to different needs and localities. More particularly, an intermediate guideway      far in endless chain      is made use of as a  pacer element between supporting sides     of the assembly, thus providing a simple and stable  construction,  Similarly  shaped fastening  devices moreover, serve as joint pieces between different guideway sections, thus facilitating fitting-up and reducing cost.

Title: Rechargeable battery pack and charger unit combination
Inventor: NAKAMURA KATSUJI
IPC: H02J7/04
Filed: 1988-06-17
Granted: 1991-11-26
Abstract: ABSTRACT          "RECHARGEABLE BATTERY PACK AND CHARGER COMBINATION"  A battery pack containing a rechargeable battery is detachable to a charger unit for charging under the control of a charging circuit in the charger unit.  The battery pack includes a sensor output circuit which comprises a temperature sensor for sensing the temperature of the battery being charged.  A voltage dividing resistor network is formed in the sensor output circuit and receives a constant current from the charging circuit upon attachment of the battery pack to the charger unit such that it provides an enable signal of a first voltage level to the charging circuit for allowing the charging of the battery at a first charge rate so long as the sensed battery temperature is below a predetermined reference level.  When the sensed battery temperature exceeds the reference level, the voltage dividing resistor network responds to provide a stop signal of a second voltage level for inhibiting the charging at the first charge rate.  Also included in the sensor output circuit is a hold circuit which holds to provide the stop signal to the charging circuit once the sensed temperature exceeds the reference level.

Title: Apparatus and method for producing uniform, fine boron-containing ceramic powders
Inventor: WEIMER ALAN W
IPC: C01B35/04
Filed: 1989-02-03
Granted: 1995-02-14
Abstract: Uniform, fine ceramic powder is prepared using an apparatus comprising a cooled reactant transport member that includes an annular gas--flow space through which a sweep gas flows thereby inhibiting contact of reactants with internal reactor chamber surfaces; a reactor chamber (16); a heating means (40); and a cooling chamber (42).  The reactor chamber defines a reaction zone heated by a heating means positioned to maintain an area of the reaction zone, positions adjacent to the reactant transport member at a desired temperature.  The cooling chamber defines a cooling zone that communicates with the reactor chamber.  The transport member temperature and the cooling chamber temperature are below that of the reactor chamber.  The apparatus may be used to produce, via rapid carbothermal reduction, boron-containing ceramic powders by (1) feeding a mixture of boric oxide or a hydrate thereof and a carbon source into the reactor chamber described above through the cooled reactant transport member at a temperature below the melt temperature of the reactants; (2) reacting the reactants at a temperature above 1400°C in the reaction zone to form a uniform, fine boron-containing ceramic powder; and (3) cooling the ceramic powder product in the cooling zone.  A sweep gas passing through the gas flow space minimizes contact of reactants with internal reactor surfaces.

Title: Weldless pavement module
Inventor: BETTIGOLE NEAL H
IPC: E01D19/12
Filed: 1989-02-08
Granted: 1992-04-28
Abstract: WELDLESS PAVEMENT MODULE           ABSTRACT OF THE DISCLOSURE      The present invention is directed to a weldless pavement mod-ule and a method for making a weldless pavement module.  Each of the primary load bearing bars is formed with openings for receiving slotted secondary load bearing bars which are passed through the pri-mary load bearing bars in a substantially horizontal position and which are rotated into a vertical position.  The size and shape of the open-ings and the slots permit the combination of primary load bearing bars and secondary load bearing bars to be skewed to form a nonrectang-ular parallelogram configuration.  Simple tack welds are used to tem-porarily hold the grating in its desired configuration.  A concrete component encases at least the top surface of the grating base mem-ber and permanently secures the elements of the grating base member together.  The use of tack welds eliminates the requirement that the grating base member be bent into a convex shape prior to welding. A simple flat jig is used.
