Patent CA-2201796-C (CA)
Title: Lens injection-compression-molding method
Inventor: SAITO KIYOHIRO
IPC: B29D11/00
Filed: 1997-04-04
Granted: 2001-09-18
Abstract: In an injection step, actual injection speed V is closed-controlled so that the actual injection speed V becomes equal to first or second preset speed V1 or V2 while comparing the actual injection speed V with the first or second preset speed V1 or V2 in the section between S0 and S1 from the time when injection of molten resin is started up to the time when the molten resin reaches this side of a gate portion 46 or the section between S1 and S2 from the time when the molten resin reaches this side of the gate portion 46 up to the time when the molten resin reaches the inside of a cavity 3. The injection speed V is open- controlled to third preset speed V3 in the section between S2 and S3 from the time when the molten resin reaches the inside of the cavity 3 up to the time when injection of the molten resin is completed. Because a high injection speed can be secured and an injection speed change can be decreased, it is possible to decrease the frequency of a feed history appearing on the surface of a molded product.

Title: Inflatable combination cargo packing bag
Inventor: ZENTMYER HUGH J
IPC: B65D81/05
Filed: 1997-04-08
Granted: 2000-12-26
Abstract: An inflatable dunnage bag is comprised of a first and independently sealed bag that is inserted within a paper tube before the tube ends are sealed to form a second, independent bag. The combination of an inner bag within an outer bag provides increased bursting strength compared to similar ply bags created as only a single bag. The combination bag is much easier to construct since at least two plies of paper that are pressed to form the inner bag are no longer part of the bag end folding and sealing process. This is especially true if the outer bags ends are sealed by stitching them together.

Title: Supported metallocene complex and process for its preparation
Inventor: GILA LILIANA
IPC: C08F4/6592
Filed: 1997-04-22
Granted: 2006-02-14
Abstract: A supported metallocene complex of a metal M selected from Ti, Zr or Hf, is prepared by a process comprising, in a first step, the reaction of an inorganic carrier containing hydroxyl groups with a compound (II) containing a cyclopentadienyl group and at least one alkoxysilane group reactive with said hydroxyl groups so as to chemically bind said cyclopentadienyl group to said carrier; and in a second step the reaction with a complex of said metal M capable of reacting with said supported cyclopentadienyl group without carrying out any intermediate metallation of the latter. This process is simple and convenient, and enables high concentrations of metal stably bound to the carrier, to be reached. The complex thus obtained can be used as solid component of a catalyst active in the polymerization of .alpha.-olefins, in the presence of a suitable co-catalyst, preferably consisting of an organo-oxygenated derivative of aluminum.

Title: Low air permeability papermaking fabric
Inventor: DESPAULT MARC P
IPC: D03D3/04
Filed: 1997-05-07
Granted: 2006-07-04
Abstract: A flat woven papermakers' fabric comprises primary warp monofilament yarns, and primary and secondary weft monofilament yarns located between and adjacent to the primary weft yarns.      The secondary weft yarns are located beneath, and in contact with, the primary warp. The dimensions of the secondary weft yarns are selected to control finished fabric air permeability arid increase the paper side surface contact area. The lower caliper fabrics provide increased cross direction stiffness at lower yarn counts. Formation of pintle receiving loop yarns in a low marking woven back pin seam, or of a streamline seam, is also facilitated, without compromising fabric properties, by selection of appropriate dimensions of the secondary weft yarns.      The primary warp yarns and the primary weft yarns are either round or flattened, in any weave pattern providing floats of the primary warp yarns extending over two or more adjacent primary weft.

Abstract: In the drying of footwear and hand-wear used outdoors in wintertime, it is known that as they are brought indoors snow, salt and sediment will drip from them, wetting and staining carpet and flooring as they are placed over the floor grills of the heating system of the common home. Many homes lack a forced air heating system and the occupants thereof must dry such items by some other means. This invention enables one to dry several items together, reducing the appearance of clutter. Heated air is directed under and around the wet items drying them efficiently asthey are suspended by the device. Water, salt and sediment, which may fall from such items, is collected by the device and contained in a removable tray. Water collected, is evaporated thereby aiding in humidifying the often too dry winter home. Items are warm as they are put on to be re-worn.

Abstract: Calls redirected off-net, which includes call forwarding and call coverage, is provided at the switch to which the call is initially directed (the principal party's switch), by monitoring the redirected off-net connection with a call classifier and listening for the appearance of ringback tone and the appearance of voice frequency energy. The call is allowed to be completed to the off-net covering end-point if voice frequency energy is detected before ringback tone appears or if voice frequency energy appears within a predetermined time-out interval. If ringback tone continues beyond a time-out interval, if voice-frequency energy is not detected within the time-outinterval, or if a call progress tone other than ringback is detected, further processing of the call is continued at the principal party' s switch to determine if another covering point is listed. If no other coverage point is listed, monitoring of the call continues until the calling party hangs up. A simulated bridged appearance is maintained at the originating switch to allow the call to be picked up at the covered station at any time.

Abstract: A simplified analog passive infrared motion detection circuit operates using only four operational amplifiers. A first amplifier is used as part of a bandpass amplifier circuit, a second is used in an inverter circuit, a third is used in an integrator circuit and a fourth is used in a threshold comparator circuit for generating an alarm output signal. The circuit is built using a single quad op amp IC package and is economical to manufacture. The third op amp can alternatively be used as a passive infrared sensor preamplifier and a transistor can be used in the integrator circuit, so that a regulated power supply for the circuit is not needed.

Title: Activity measurement
Inventor: ANDERSSON PETER
IPC: A01K11/00
Filed: 1996-12-30
Granted: 2005-08-23
Abstract: A motion sensor unit (11) is intended to be carried by a domestic animal. The motion sensor unit (11) operates in parallel to and independently of a conventional transponder unit (1). The motion sensor unit (11) contains a motion detector (14) for measuring the activity of the animal by providing electrical pulses when the animal moves. Each hour is subdivided in a number of intervals in each one of which it is determined if the activity has exceeded a certain threshold. If it is the case, a count value is incremented. The count value is then transmitted once each hour and in addition also the count values of all the 23 previous hours. By transmitting repeatedly such information a good safety is obtained in the reception of the information signal, and this information can be used for complicated evaluation pressing in a processor (7) or a supplementary personal computer (9).

Title: Search optimization system and method for continuous speech recognition
Inventor: STUBLEY PETER R
IPC: G10L15/19
Filed: 1998-11-04
Granted: 2007-05-15
Abstract: A system and method for continuous speech recognition (CSR) is optimized to reduce processing time for connected word grammars bounded by semantically null words. The savings, which reduce processing time both during the forward and the backward passes of the search, as well as during rescoring, are achieved by performing only the minimal amount of computation required to produce an exact N-best list of semantically meaningful words (N-best list of salient words). This departs from the standard Spoken Language System modeling which any notion of meaning is handled by the Natural Language Understanding (NLU) component. By expanding the task of the recognizer component from a simple acoustic match to allow semantic information to be fed to the recognizer, significant processing time savings are achieved, and make it possible to run an increased number of speech recognition channels in parallel for improved performance, which may enhance users perception of value and quality of service.
