Patent CA-2190938-A1 (CA)
Title: Computer graphics circuit
IPC: G06T15/83
Filed: 1996-03-21
Abstract: In the Figure, a memory device (RAM) (1) stores cosLv[cos(Lh - Nh) - 1], a memory device (ROM) (2) stores cosNv, a memory device (RAM) (3) stores cos(Lv -Nv) and a memory device (ROM) (4) stores cosNh. The variable of the trigonometric function of each memory device 1 to 4 is one of Nh and Nv. Therefore, the individual memory devices require only a limited capacity that suffices the range of input variables. Adders (6a and 6b) output cos.theta. and cos.alpha., respectively. A multiplier (5c) produces a diffusion component by multiplying a coefficient Id by cos.theta.. A mirror surface component can be obtained after passing through a memory device (7) for generating cosn.alpha. using a mirror surface reflection factor n by the multiplication of a reflection coefficient Ir by a n multiplier (5d). Final brightness Ip is obtained by adding Id cos.theta. and Ir cosn.alpha. by an adder 6c.

Patent CA-2191126-A1 (CA)
Title: Improved propylene copolymer heat seal resin and articles therefrom
Inventor: MACALPIN JAMES JOHN
IPC: B29C65/02
Filed: 1995-04-27
Abstract: The temperature at which propylene-copolymers produced by metallocene catalyst form a full strength heat seal is found to be lower than correspondingly similar melting point copolymers produced by conventional Ziegler-Natta catalyzed copolymers. At similar melting points, films made from metallocene catalyzed copolymers were also found to exhibit higher tensile modulus values relative to films from Ziegler-Natta catalyzed polypropylene copolymers. Films and articles made in accordance with the present invention offer greater stiffness properties, yet are sealable at lower temperatures than currently available.

Title: Methods of Enhancing Capacity of Transformer Equipment and of Power Flow Control Using Phase-Shifting Transformers and Series Impedances in Parallel Arrangements
Inventor: PELLETIER PIERRE
IPC: H02J3/06
Filed: 1995-11-14
Abstract: To enhance the capacity of a transformer apparatus for a polyphase AC network, a constant current transformer branch (6) is connected in parallel with one or several conventional transformer branches (4) already in place in the transformer apparatus or added to form the transformer apparatus. The constant current transformer branch (6) includes a phase-shifting transformer (10) in series with reactive elements (12).

Title: Gene controlling floral development and apical dominance in plants
Inventor: AN GYNHEUNG
IPC: C12N15/29
Filed: 1995-10-13
Abstract: The present invention provides compositions and methods for affecting the transition from vegetative to reproductive growth in a wide variety of plants. A MADS-box gene from rice, OsMADS1, has been isolated and sequenced. Expression of OsMADS1 in transgenic plants dramatically alters development, resulting in early flowering plants with reduced apical dominance, causing both long-day and short-day plants to flower under both short-day and long-day conditions. OsMADS1 is a key regulatory factor determining the transition from shoot apex to floral meristem and is a target for action of flower induction signals.

Title: Winter footwear and hand wear water and sediment collector and dryer
Inventor: KINGMA GERARDUS E
IPC: D06F58/10
Filed: 1997-06-06
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.

Patent CA-2221454-A1 (CA)
Inventor: SOLOMON NATALIE A
IPC: C12Q1/68
Filed: 1996-05-17
Abstract: The present invention provides a method of detecting the amount of a target sequence which may be present in a test sample. The method uses an aggregate primer series, which comprises at least two primer sets, in an amplification reaction to detect the relative concentration of a target sequence which may be present in a test sample. The primer sets have different sensitivities and hybridize with sub-target sequences which are different regions of the target sequence. The method generally comprises cycling a test sample suspected of containing a target sequence, an aggregate primer series, and means necessary for performing an amplification reaction; and detecting any amplified sub-target sequences. Based on a qualitative detection of the amplified sub-target sequences generated by individual primer sets, the relative quantity of the target sequence can be determined.
