Title: Customer order processing system
Inventor: FUYAMA SEIJI
IPC: G06Q30/06
Filed: 1992-11-23
Granted: 1998-09-29
Abstract: A customer order processing system includes a register terminal for sequentially transmitting customer order registered in the register terminal to a kitchen video controller, wherein the customer orders as received are sequentially displayed on a display device of the kitchen video controller.  Upon completion of preparation for a customer order by a person in charge, the display of that customer order on the display device of the kitchen video controller is erased by manipulating a control switch.  A time length between the reception of the customer order and the erasure thereof is measured and stored as service time data in the kitchen video controller.  The register terminal totalizes the service time data transmitted from the kitchen video controller to issue a management report.  With this customer order processing system, not only the service times taken for the disposition of customer orders can be managed but also speedy transmission of the customer orders to the kitchen as well as a reduction in the time taken for the preparation of the customer orders can be achieved.

Abstract: In this panel, a frame (1) displays an encircling flange (2) and a respective web-shaped rim (3) at each of two parallel sides and a respective parallelepipedonal rim (4) at each of two parallel sides. The rims (3; 4) are received by a recess of a mounting plate (5) so that the encircling flange (2) covers over the recess and lies frontally against the mounting plate (5). Arranged on the inward side of the parallelepipedonal rims (4) are supports (7) and countersupports (8), by means of which a plate is retained. The parallelepipedonal rim (4) is penetrated over the entire length by a channel which is interrupted by a web (14) centrally at the side and at the side remote from the flange (2) displays a first opening (15) and a second opening (16) for each channel half. A locking bar serving as fastening element is arranged to be displaceable in each channel half. A head part (18) of the locking bar stands in connection with a foot part by means of a spring, wherein the foot part bears on the web (14). In the assembly position of the locking bar shown by interrupted lines, a first locking dog (24) detents with a second opening (16) against the spring force. A light pressure, which releases the detent, on a first guide finger (22) suffices for the one-piece locking bar consisting of elastic synthetic material jumping from the assembly position into the retaining position or the base position.

Granted: 1998-02-10
Abstract: The invention relates to a method and a wire group in a drying section provided with single-wire draw in a paper machine or paper finishing machine.  A paper web to be dried is passed on support of a drying wire alternatingly over heated cylinder faces of drying cylinders  and  over  leading  rolls  or  other  equivalent  drying cylinders.  The paper web is pressed into direct contact against the heated cylinder face of the drying cylinders and,  on the leading rolls, the paper web is placed on the outside face of the drying-wire loop at a side of the outside curve.  In the invention, the difference in speed of the paper web which the paper web would have during operation of the drying section on the turning sectors of the drying cylinders and the leading rolls  is reduced by dimensioning of the structure of the drying wire in the direction of  thickness  and by  selecting  appropriate materials  for the structure of the drying wire.

Title: Reducing agent regeneration system
Inventor: TENCH D MORGAN
IPC: C23G1/36
Filed: 1993-06-16
Granted: 1998-11-17
Abstract: A system is provided for regenerating reducing agents used in ancillary chemical or electrochemical such as restoring solderability of electronic components. The system includes a cathode, an anode, and an electrolyte system that is separated by a semipermeable ionic barrier into a catholyte and an anolyte. The catholyte includes the reduced member of a redox couple, which can be regenerated electrochemically. The redox couple of the electrolyte system is charged like a battery and discharged during the ancillary process. Regeneration of the reduced member of the redox couple is accomplished at the cathode. The cathode comprises an electrode having a high hydrogen overvoltage so that sufficiently negative potentials can be attained while minimizing hydrogen evolution. Chemical balance is maintained by the semipermeable ionic barrier, which permits proton migration from the anolyte to the catholyte but acts as a barrier against diffusion and migration of cations from the catholyte to the anolyte. Ideally, the anodic reaction is breakdown of water to form oxygen, which is vented, and protons that migrate across the ionic barrier to the catholyte replacing protons consumed in the ancillary process. The overall reaction in a system for restoring solderability of electronic components in reduction of metallic oxide to metal and release of oxygen, with no net chemical change in the composition of the regeneration system.
