Patent CA-2152392-A1 (CA)
Title: Network adapter with host interrupt and indication management
Inventor: EMERY SCOTT ANDREW
IPC: G06F13/00
Filed: 1993-12-28
Abstract: Indication and interrupt signals generated by a network adapter (3) representing asynchronous events are managed by a host system (1). The network adapter (3) comprises a first mask logic (10) for selectively disabling the indication signals from being stored in a first memory location (10a-c) by the host writing to a first mask register (10).     A second mask logic which is coupled to the first memory location (l0a-c) also selectively disables the indication signals from being stored in the second memory location (10a-c) creating two levels of status information. The indication signals may also be disabled from being stored in the second memory location (10a-c) responsive to the host writing to a second mask register. The first memory location (10a-c) may be read from the host (1) in order to determine whether a network event' occurred during an interrupt service routine, while interrupt means (10) generates an interrupt signal to the host (1) responsive to the value in the second memory location (10a-c). A third level of control is provided by an internal counter which allows for automatic enabling and/or disabling of a plurality of indications and interrupts with and without explicit commands in the host driver subroutines.

Title: Ball and socket and test board arrangement
Inventor: ROSEBUSH PAUL
IPC: G08B13/22
Filed: 1995-08-03
Abstract: A monitoring device such as a cart scanning system for a supermarket check-out employs a series of scanning devices located beside the cashier's check-out, for purposes of detecting the presence of objects on the bottom tray of a shopping cart. The correct functioning of such a scanning system requires precise aiming of the individual scanning devices and preferably a test readout to give evidence of the satisfactory operation of each of the scanning devices, in view of their integrated relation in the total functioning of the system. Theaiming is achieved by a special adjustable socket mount for each scanning device, and a series of signal outlet sockets accommodating a removable plug-in test unit with LED readouts, for visually checking the operation of each one of the scanning devices.

Title: Improving mechanical properties of aluminum-lithium alloys
Inventor: CHO ALEX
IPC: C22C21/00
Filed: 1994-03-09
Abstract: Strength and ductility for aluminum-lithium alloy wrought product in the transverse direction is improved by subjecting these types of alloys to improved T8 temper practice. The wrought product, after solution heat treating and quenching is subjected to a multiple step stretching sequence prior to aging, the total percent reduction for the multiple step stretching sequence ranging between 1 and 20 percent reduction. In the multiple step stretching sequence, each of the stretching steps may have the same or different amounts of percent reduction to achieve the desired total percent reduction. An aluminum-lithium alloy wrought product subjected to the improved T8 temper practice has increased tensile yield stress and percent elongation in its transverse direction to facilitate commercial application of the product in high strength  applications.

Title: Automated printing press with reinsertion registration control
Inventor: SCHULTZ JOHN E
IPC: B41F13/12
Filed: 1994-06-01
Abstract: An automated printing press (10) is provided with a plurality of printing stations (13), each having a printing mechanism (60) which prints at least one component image at spaced apart locations along a web (11). Each printing  mechanism   (60) is also positionable to one side of the press to facilitate its servicing.      Computers (400, 405) are used for precisely and repeatedly controlling actuation of the printing mechanism     (60) in and out of position for printing and for precisely registering the component images being printed by the multiple printing stations (13). Each station (13) has a microprocessor based computer controller (407) for precisely registering the printing rollers (61) among each of the stations (13) and with respect to a reprinted component part of a composite image on a web (11) that may have been removed from and reinserted into the press (10), deforming in the process such that the repeat lengths of the reprinted parts have changed and may vary along the length of the web (11). Measurements are made by sensors (350) of a series of repeat lengths on the web (11), a regression analysis is performed and a prediction made of a constant or recurring component in the next image to be encountered at each respective station (13). The circumferential speed of the print roller (61) at each station (13) is separately controlled in accordance with a respective error prediction to control the length of the image printed at the station to that already on the web (11). The speed is controlled by pulses sent to a stepper motor (327) of a harmonic drive (275) at each station (13). The pulses are spaced evenly over the print length of the image.

Title: Human calcium sensor
Inventor: AKERSTROEM GOERAN
IPC: C12N5/10
Filed: 1994-05-24
Abstract: The present invention relates to the isolation of a cDNA clone encoding the calcium sensor in human placenta and subsequent Northern blots confirming the mRNA expression also in human parathyroid and kidney tubule cells. Close sequence similarity is demonstrated with the rat Heymann nephritis antigen, a glycoprotein of the kidney tubule brush border with calcium binding ability. Immunohistochemistry substantiates a tissue distribution of the calcium sensor protein similar to that previously described for the Heymann antigen. It is propsed that the identified calcium sensor protein constitutes a universal sensor for recognition of variation in extracellular calcium, and that it plays a key role for calcium regulation via different organ systems. The calcium sensor protein belongs to the LDL-superfamily of glycoproteins, claimed to function primarily as protein receptors, but with functionally important calcium binding capacity.

Title: Helicopter landing gear assembly
Inventor: COLLINS BOBBY A
IPC: B64C25/52
Filed: 1994-11-04
Abstract: An improved helicopter landing gear assembly (12) to substantially increase useful service life.  The crosstubes (14) are constructed of a material that allows use of thicker crosstubes thereby reducing the operating stress in the crosstubes (14) and helping to increase the fatigue life, while at the same time preserving the required energy absorption characteristics.  The inside and outside of the crosstubes (14) are shot peened to help increase the fatigue life.  The crosstubes (14) are formed in an unstable temper condition thereby reducing the stress that is induced into the part during formation, and thus connected to the crosstubes (14) by fasteners (64) located at the sides of the straps (20) and closer to the neutral bending axis of the crosstube (14) so that the fasteners (64) and the fastener holes (48) are subjected to lower stress levels.   The combination of these improvements results in a substantially increased life of the landing gear assembly.
