Abstract: A method and apparatus concerning electronic financial transaction processing systems used by customers of certain credit or electronic banking card-issuing institutions are disclosed. The present invention involves two levels of secure interaction between the customer and the card-­issuing institution. The first level of interaction involves the enrollment of a customer in the institution's electronic financial transaction processing system. The customer either selects or is issued a personal identification number and a card encoded with a personal key. The personal key and personal identification number are used to generate a PIN transmission number and personal verification number, which is stored in bank records. The second level of interaction involves the authorization of a customer's use of the electronic financial transaction processing system for executing an electronic transaction. The customer enters his personal identification number and the system reads his encoded card, both of which are used to generate a candidate PIN transmission number. The candidate PIN transmission number is transmitted to a remote processing center by computer network. The system, at the remote processing center, generates a candidate personal verification number using the transmitted candidate PIN transmission number and compares the candidate PIN transmission number for parity with a PIN transmission number stored in the institution's records.

Abstract: A fluid distributor valve, for use in an aircraft fire protection system, comprises a rotary valve member (60) driven from a normal position in which inlet ports (52,54) communicate with outlet ports (56,58) respectively to a switched position in which ports (52,54) communicate with ports (58,56) respectively by means of an explosively actuated piston (70). A piston housing (66) is mounted on valve body (50) and communicates with the interior of the body through a passage (68). The valve member is locked in its normal position by means of a spring-loaded plunger (76) carried by an actuator portion (72,74) of the valve member which is released by actuation of the piston. The piston itself serves to lock the valve member in its switched position. There is also disclosed an explosively actuated fire extinguisher outlet head comprising a sealing plug having a head part which is sheared by an explosive charge upon actuation of the extinguisher head to permit release of extinguishant. The sheared head part is guided along a curved path into an end position in which it is retained so as not to impede discharge of extinguishant through a discharge passage.

Abstract: It is desirable to provide a book binding process which effectively binds coated and uncoated paper together, while retaining the advantages of low temperature glues, such as animal glues and cold emulsion glues. However, animal glue does not adhere well to coated paper stock nor does animal glue adhere well to a cold emulsion primer adhesive. Therefore, the present book binding process includes applying a coating of cold emulsion primer adhesive to a roughened and slashed backbone (42) of a book block (40) to bind the pages in the book block (40) together, and, then, removing the coating of cold emulsion primer adhesive, preferably by scraping. The scraped backbone is relatively clean, so that a coating of animal glue will adhere well to the backbone. The coating of animal glue acts as a cover adhesive which binds a cover to the backbone (42) of the book block (40).

Abstract: The present invention includes two variations of an apparatus which generate a version of the IORC *  bus signal that is supplied to the read strobe input of a floppy disk controller that is asserted at the appropriate time during verify cycles between the floppy disk controller and a DMA controller. These designs allow an 82077 floppy disk controller to operate properly in FIFO mode when it is being used with software that does not require generation of this signal. The designs include use of a PAL and certain bus signal inputs to generate a signal which is asserted at the appropriate times during verify transfers. This signal is combined with the regular IORC bus signal to produce the signal that is provided to the read strobe input of the floppy disk controller.

Abstract: A machine or machine section (12) for squaring folded container blanks has a conveyor (16)for conveying slotted and partially folded container blanks (130). A folding device (34) completes folding of each con­tainer blank while being conveyed by the conveyor (16). A gauge plate (44) is inserted in a slot (142) in each of the slotted and partially folded container blanks (130). A mechanism (38, 46) moves the gauge plate (44) in timed sequence with the conveyor (16), inserts the gauge plate in the slot (142) before completion of folding of the respective blank (130) in order to "square" the folded blank, and then withdraws the gauge plate (44) from the slot. Overlapping flaps (132, 138) of each folded blank may be tacked together during "squaring" by drops of hot melt adhesive (140) which subsequently hold the flat folded blanks (124) square while the conventional slow drying water soluble glue dries.

Abstract: The display control apparatus of a ferroelectric liquid crystal panel (21) of the present invention does not apply a selective voltage (A) to the scanning electrode (Li), when display data (DATA) of picture elements (Aij) on the scanning electrode (Li) displayed at present and display data (DATA) in the following frame are same, or applies the selective voltage (A) only to some of the electrodes (L). Accordingly, even in the case of ferroelectric liquid crystal panel (21) having a large number of scanning electrodes (L), a frame period is shortened by the decreased number of scanning electrodes (L) selected in one frame. Thereby, the response time for the display of data (DATA) inputted can be shortened.

Abstract: An apparatus and method for cutting continuous webs (W) having varying thicknesses, widths, and compositions into sheets. The apparatus includes a pair of oppositely rotating web feed assemblies (12,13) employing a unique floating nip and clamping mechanism which engages the web (W) and advances it a specified length past a poised cutting blade assembly (31) and onto a simultaneously driven exit assembly. After the desired length of web (W) has been fed, the drive mechanisms stop, and the cutting blade assembly (31) cycles to clamp the web (W) on the downstream side and cut. During the cutting stroke the web (W) is held taut on the upstream side by the web feed assemblies (12,13). Upon completion of the clamping and cutting stroke, the cutting blade assembly (31) returns and stops at its poised position.

Abstract: A method of maintaining the consistency of cached data in a client-server database system. Three new locks--a cache lock, a pending lock and an out-of-date lock--are added to a two-lock concurrency control system. A new long-running envelope transaction (69) holds a cache lock (45) on each object cached by a given client. A working transaction of the client works only with the cached object until commit time. If a second client's working transaction acquires an "X" lock on the object (167) the cache lock is changed to a pending lock (51); if the transaction thereafter commits (171) the pending lock is changed to an out-of-date lock (47). If the first client's working transaction thereafter attempts to commit, it waits for a pending lock to change (67); it aborts if it encounters an out-of-date lock (49); and otherwise it commits (61).
