Patent CA-2202217-A1 (CA)
Inventor: SAMPSON WESLEY C
IPC: G06F17/30
Filed: 1997-04-09
Abstract: A  method  and  apparatus  for  indexing  data  entry records groups in a plurality of raw data entry records, each data entry records group having at  least one data entry record with a group identifier and with at least one key field containing an item which is included in a master list  of  items  in the  raw data being  indexed.   A data records  group  is  read  and  a  tally  of  a  key  number representing a total number of the key fields in the data entry records is generated.   In some cases the key fields are  sorted  in  a  predetermined  sequence,  duplicate  key fields are removed and the key number is adjusted for the key fields removed.  An index record having a predetermined number of key fields equal to the key number and pointer to locate the indexed data is generated.  Each item in the key fields  of  the  data  entry  records  group is  mapped  to generate a corresponding item indicator in the key fields of the index record.  If the index record is new, a pointer is attached for location of the specific data records group which  is  represented by  that  index  record.    A  repeat mapping to a specific index record will modify the data location method  to  include  the  record  group  being processed.

Title: Automated folder nipping roller adjustment
Inventor: SHARPLES IAN A
IPC: B65H45/22
Filed: 1997-09-09
Abstract: Web feed apparatus , for example in web printing and folding apparatus, has a pair of opposing rollers, one (28) on a fixed axis and one (22) laterally movable to define an adjustable nip gap between their peripheries.      The gap is automatically set and adjusted by a setting screw (4) driven by a servo motor (60) with rotation of the screw monitors by a potentiometer sensor (64). A stop collar (52) on the screw limits axial displacement thereof to determine the set nip gap and a spring (50) urges the rollers towards each other but permits displacement under overload conditions. A rectilinear sensor (54) senses said conditions by monitoring relative displacement by of the stop collar and a programmable control system processes signals from the sensors and operates the servo motor accordingly.

Title: Process for compacting and sintering a powdered metal preform
Inventor: HUBBARD THEODORE RUSSELL
IPC: B30B11/00
Filed: 1996-04-11
Abstract: A process is disclosed for forming a pressed metal part in which a preform (122) is inserted into a pressed metal mold. The mold is then filled with powdered metal. The powdered metal and preform are compacted to create a compacted metal part wherein the preform defines an adjacent volume next to the compacted metal part. The compacted metal part is ejected from the mold and sintered to create a sintered metal part. The preform is removed by the sintering step in such a way that the adjacent volume becomes a void region.  The preform can be formed of copper so that, upon sintering, the preform is removed from the sintered metal part through infiltration. Alternatively, the preform can be formed of zinc so that, upon sintering, the preform is vaporized and thereby removed from the sintered metal part. The void region created by the removal of the preform can be an undercut, a taper, an annular groove, a thread or an internal cavity. In this way, the present invention eliminates the need for machining such surfaces as has been necessary using previous compaction methods.
Patent CA-2221608-A1 (CA)
Title: Transmitting data from frame-scanning display device
Inventor: MILLER J MARK
IPC: G04G21/00
Filed: 1996-05-07
Abstract: The invention encompasses a system and method for serially transferring a sequence of data bits having binary values. This includes a step of displaying sequential display frames (100) on a frame-scanning graphics display device (14), wherein each sequential display frame is associated with an individual group of data bits. Each group (102, 104) of data bits is associated with one or more data framing bits (110, 112). The framing bits are inverted from one sequential display frame to the next. Within each display frame, sequentially-scanned data transmission lines are selectively illuminated to represent the individual groups of data bits associated with the display frames and their associated data framing bits. Bits having a first binary value are represented by illuminated display frame lines. Bits having a second binary value are represented by non-illuminated display frame lines. A receiving device (12) can determine the validity of a particular display frame by determining whether the framing bits of the display frame are inverted from the framing bits of the previous display frame. Further aspects of the invention provide error detection and correction capabilities, and also provide methods of making the most efficient utilization of the data transfer mechanism.

Title: Surge prevention control system for dynamic compressors
Inventor: MCLEISTER LARRY D
IPC: F04D27/02
Filed: 1997-01-02
Abstract: A surge prevention control system for use with a dynamic compressor provides a multiple module controller - for operating an anti-surge valve to bypass flow around the dynamic compressor. The multiple module controller includes a PID control module and a rate control module.     The PID control module controls the anti-surge valve to control the operating point of the dynamic compressor about the surge control line. The rate control module uses the rate of approach of the operating point to the surge control line as its process variable. In the event of high rate of approach, the rate control module takes control of the anti-surge valve. The setpoint of the rate control module is adjusted to open the anti-surge valve to control the rate of approach to the surge control line to minimize the overshoot of the PID control.
Patent CA-2231444-A1 (CA)
Inventor: MCLEISTER LARRY D
IPC: F04B49/10
Filed: 1997-01-02
Abstract: A control system prevents recurrence of surge in a dynamic compressor. An anti-surge valve bypasses flow and is operated by the control system between a low limit and a full open position. The low limit is initially established to be zero, or a fully closed anti-surge valve. In the event of a compressor surge, the system detects a position of the anti-surge valve at the onset of surge, and stores a position related to the detected position as a new low limit. The stored position is preferably the detected position plus a small increment in order to prevent recurrence of the surge event.

IPC: H04B3/56
Filed: 1998-07-07
Abstract: Methods    and    apparatus    for    establishing communications  between electrical  and electronic  devices utilizing existing power signal distribution networks are disclosed.   In such methods and apparatus the transmitting and receiving components of such devices are coupled between line and ground.   Such coupling is achieved utilizing a coupler, a first frequency reactive device, such as a drain coil or inductor,  connected in series with neutral and a second  frequency  reactive  device,  such  as  a  capacitor connected between neutral ground.   For use with existing electronic   equipment,   an   adaptor   for   coupling   the communications signal to a power signal distribution network is  also  disclosed.    Since,  line  and neutral  paths  may sometimes  be  mis-wired,  the  apparatus  and methods  also disclose the use of a switch for enabling the coupling of a communication signal when a power signal is sensed on the line path.
