Title: Method and apparatus for improved mixing in fluids
Inventor: BIRCHER KEITH G
IPC: B01F13/10
Filed: 1998-09-21
Abstract: The present invention pro-vides an apparatus and method for accomplishing fluid disinfec-tion by passing fluid flow through a uniform array (3B) of ultraviolet lamps having cross sections per-pendicular to the direction of fluid flow that define channels (8) for the fluid flow. Positioned next to the end of each lamp (5) at the entrance of the fluid flow are tri-angular shaped delta wings hav-ing surfaces inclined at an an-gle to the direction of fluid flow.  The interaction of the fluid flow with each delta wing creates a pair of vortices (10) that rotate in the same direction or in direc-tions opposed to each other. The counter-rotating vortices (10) rein-force each other to minimize dissi-pation of their mixing strength as they move down the channel (8).  Due to these co-reinforcing prop-erties these counter-rotating vor-tices (10) more promote efficient mixing of the fluid which is re-quired to achieve more efficient use of the light in the UV  disin-fection systems, along with heat and/or mass transfer in chemical reactions. Although the present invention is described in particularity as embodied in a UV reactor system, it will be understood by those skilled in the art that the present invention has equal applicability to other types of arrayed flow systems in which increased fluid mixing is desired.

Title: System and method for electronic inventory
Inventor: WILLIAMS ROBERT A
IPC: G06Q20/20
Filed: 1998-11-20
Abstract: A system and method for conducting an inventory of tags, wherein each tag is assigned a Tag ID and a manufacturer number. Each tag can be attached to an item to take inventory of those items. A tag reader transmits a wake-up signal followed by at least one clock signal. Each tag increments a first tag count in response to the clock signals, and transmits the Tag ID assigned to the tag when the first tag count corresponds to the Tag ID assigned to the tag. The tag reader records the transmitted Tag IDs. When more than one tag transmits simultaneously, the tag stores the Tag ID in order to resolve the contention when the first read cycle is complete. In the second read cycle, the tag reader transmits the contended Tag ID followed by at least one clock signal. Each tag that contended for the transmitted Tag ID  increments a second tag count in response to the clock signals, and transmits the manufacturer number assigned to the tag when the second tag count corresponds to the manufacturer number assigned to the tag. The tag reader records transmitted Tag IDs, completing the inventory of the tags.
Patent CA-2313203-A1 (CA)
Title: Mold heater startup method
Inventor: LINEHAN THOMAS P
IPC: B29C45/74
Filed: 1998-12-07
Abstract: A method for mold heater startup and sequencing detects the heater zones associated with greater mass and allows them to heat up before zones of lesser mass, thereby reducing wear of the associated mechanical components and minimizing degradation of plastic material. The zones of smaller mass are kept at minimal temperatures until the zones with greater mass reach a set point. The system is capable of detecting multiple levels of thermal load and provides appropriate sequential startup of the identified thermal loads. The operator may also manually program the system to override certain automated sequences in order to ensure an optimal startup sequence. The sequencing of power application to large heaters also minimizes the peak current draw of the system.

Abstract: A method of a receiver determining the timing of a signal transmitted in a time-slotted manner, the signal comprising a sequence of information which is repeated at a known interval and has at least a known minimum length. The method performs correlation operations between groups of received slots of information, the groups spaced by the known interval. The groups are moved through the received signal, adding and removing slots, to locate a maximum correlation value sum for the group which should correspond to the timing of the slot. The method also can be used to determine a frequency offset at the receiver and/or an initial phase.
