Patent CA-2199868-A1 (CA)
Title: Compact Spectrophotometer
Inventor: BERG BERNARD J
IPC: G01J3/50
Filed: 1995-09-14
Abstract: A portable spectrophotometer (100) includes a rotating wheel (214) provided with a plurality of filter characteristics in the 400 to 700 nanometer wavelength range and operated at a constant speed. The filters are moved between an optical conduit (210) and a photoelectric sensor (220) as the wheel is rotated. Light reflected from the object sample is conducted through the optical conduit (210) and focused on the optical sensor (220) by means of a focusing lens (252). A side sensor (222) receives light from one of the three lamps (206) through the filters as the wheel is rotated and provides output signals which are used as reference signals for the individual filters. An integrating sphere (512) with an aperture (541) for conducting specular-included light reflected from the object and an aperture (543) for conducting specular-excluded light from the object is incorporated with a rotatable filter wheel (520), with a plurality of filters having filter characteristics in the 400-700 nanometers wavelength range.

Title: Portable trench barrier for insect pests in agriculture
Inventor: VERNON ROBERT S
IPC: A01G9/28
Filed: 1997-03-14
Abstract: A portable trench barrier is capable of greatly reducing the number of beetles migrating into a cultivated area, such as a field of potato plants.  The device comprises a series of linear barrier sections and connector pieces joined together to enclose and protect a cultivated area.  Each linear barrier section comprises an extruded plastic section having (a) an elongated floor section, (b) a pair of continuous leg portions extending downwardly from the side edges of the floor portion. The leg portions are adapted to penetrate the soil and form a continuous sub-surface barrier.  A pair of opposed upwardly inclined elongated ramp portions extending upwardly and inwardly from the side edges of the floor portion, these ramp portions terminating in downwardly curved free edge portions having smooth outer surfaces with the curved free edge portions of the opposed ramp portions forming therebetween a gap having a width of up to about 20 mm.  The opposed ramp portions and gap are arranged such that beetles are able to climb the ramp and continue along the ramp until they reach a point on the curved free edge portion where they lose their footing and slide down into and are trapped in a chamber formed by the floor section and ramp portions.

Title: Integrated optic dispersion compensators
Inventor: HATAMI-HANZA HAMID
IPC: H04B10/2513
Filed: 1997-08-08
Abstract: Photons of different wavelength propagate with different speed and are delayed different time after propagating in an optical fiber transmission link. An integrated optic circuit dispersion compensator reflects different wavelength sub-bands of the optical signal from different distances of an optical waveguide by a group of gratings. Different wavelengths then arrange to experience different delays in time in a reverse order as they do when propagating through the fiber optic transmission link. The effect of dispersion substantially can be fully compensated for any amount of dispersion. The dispersion compensator does not spatially separate the wavelengths and therefore it will be almost loss-less. Light is divided into two part by an input coupler and travel through the two identical waveguides but with an equivalent of ~/2 one way propagation phase shift (at the central wavelength) difference in length. Different wavelengths are reflected at different distances by the group of gratings, with or without chirp, and propagate back towards the input coupler where they all emerge at the other port of the input coupler. The dispersion compensators are also presented in an add/drop configuration to add and/or drop one or more signal/signals among a plurality of signals in a WDM transmission system while compensating the effect of dispersion for the corresponding individual signal at the same time. The integrated optic dispersion compensators can be entirely made from sol-gel photosensitive glass. The integrated optic dispersioncompensators are low loss and compact.

Abstract: A telescopic column is movable along and installed between a flooring sill rail and a ceiling rail.  The column has an upper set of wheels engaging the upper rail and a lower set of wheels engaging the lower sill rail, for guiding the column along the rails.  A crimping head according to the invention is provided at both extremities of the column, for anchoring at selected intervals a number of vertical studs on the bottom sill rail and on the upper ceiling rail.   Each crimping head is positioned inside the C-shaped corresponding rail, and the studs are positioned so that each crimping head is flanked on both sides by two adjacent rail and stud walls.          Each crimping head comprises two knives which can pivot in opposite directions away from the column, so as to pierce simultaneously both the rail and stud walls, thus creating outturned complementary lips and a stud window engaged by the lips so as to prevent relative movement of the stud and the rail.   The pivoting knives are controlled by means of a mechanically-activated hydraulic piston.
Patent CA-2220198-A1 (CA)
Inventor: WRIGHT FRED P
IPC: G06F19/00
Filed: 1997-11-04
Abstract: A global positioning system recorder (GPSR), comprising a housing that contains a GPS receiver and associated circuitry, an antenna external to the housing and operatively connected to the receiver, a memory card slot, and control circuitry inside the housing for interfacing the GPS receiver with the memory slot. In operation, a memory element such as a PCMCIA card containing a set of operational parameters for the GPSR is inserted into the memory slot. The receiver reads the operational data from the memory card, receives GPS signals via the antenna, processes the signals to determine the position of the recorder, and writes the position data (along with the date and time) to the memory element. In a preferred embodiment, a new position data point is recorded only if the GPSR has moved since the last position data point was recorded, and/or if a parameter of interest has changed by at least a preselected amount. The GPSR may also be connected to one or more sensors that measure various environmental parameters of interest. Data from these sensors is processed, integrated with the corresponding time/position data, and stored on the memory card for later analysis.

Title: Atm adaption layer traffic scheduling
Inventor: DUBUC KEN
IPC: H04L47/21
Filed: 1998-03-30
Abstract: The ATM transmitting apparatus for transmitting messages, such as frame relay packets, associated with a plurality of connections comprises ATM layer transmission equipment for receiving multiple messages, segmenting each received message into a plurality of smaller data units, such as 48 byte AAL SAR protocol data units, and multiplexing such data units into a single stream for transport over a physical interface. A scheduler receives messages from each of the connections and transfers the messages to the transmission equipment. The scheduler can dynamically set a transmission rate for any connection, and allocates each connection whose message is transferred to the transmission equipment a substantially maximal amount of bandwidth at any given time during the transmission of the message, to thereby minimize interleaving of data units from the various connections and reduce the average latency (per unit of message) in transmitting the messages across a network.

Abstract: The invention concerns a press section in a paper machine, which press section comprises a compact combination of rolls, which rolls form a number of press nips with one another, which nips remove water out of the paper web (W). Between said nips, the paper web (W) has a closed draw supported by a press fabric or by a roll face. The press section includes a centre roll (20; 20A), in connection with which there are at least two press nips (N2, NP1; N2, NP11). The last nip placed in connection with the centre roll (20; 20A) is an extended nip (NP1; NP11). The centre roll (20; 20A) is a roll provided with circulation of heating medium (Fin Fout) and with a heated outer mantle. The outer face (21') of the mantle (21) of the centre roll (20; 20A) is heated by means of circulation of medium (Fin Fout) to such a temperature level (TS) that the dewatering of the paper web (W) in the nips (N2, NP1; N2, NP11) placed in connection with the centre roll (20; 20A), in particular in said extended nip (NP1; NP11), is intensified substantially. The invention can also be accomplished in an environment in which there are two or more separate press nips (NP12, NP22), of which nips at least the last nip is an extended nip (Figs. 7 and 7A).
