Title: Improvements relating to nursery gates
Inventor: POSTANS MARK ANTHONY
IPC: E05B65/00
Filed: 1995-09-19
Abstract: A nursery gate is provided with a pivoted latch. When the gate is swung to a closed position where it is co-planar with the keeper and hinge axis, the latch draw engages the keeper. At that time, a detent provided by the nose and the recess engages due to a spring movement of one of the part in the direction of the hinge axis. The gate is released for opening by a movement in the opposite direction against the spring so as to separate the nose and recess and allow the latch to pivot.

Title: Power sharing device
Inventor: HOLMAN FRANK T
IPC: H02J3/00
Filed: 1997-10-10
Abstract: A power sharing device is disclosed, having a primary utility in supplying powerto automotive block heaters or other auto warming devices at a user selectable duty cycle of 12.5% or 25%.  In a first mode, power is supplied to 4 outlets in a sequential manner, for 15 minutes each.  In a second mode, power is supplied to the 4 outlets in a sequential manner, for 7.5 minutes each, followed by a period of 7.5 minutes in which power is not supplied.  The user may elect to initiate a delay period, that is selectable between 1 and 2 hours, to precede the sequence of power distribution, allowing time for the car to cool before the power cycles begin.  A test circuit, activated by a pushbutton, allows a user to distinguish between the periods of time when power is not beingsupplied to an outlet as a part of the sequential sharing of power between outlets and a circuit malfunction, such as a blown fuse.

Title: Nanofabricated separation matrix for analysis of biopolymers and methods of making and using same
Inventor: LARSON MARINA T
IPC: G01N33/50
Filed: 1996-06-07
Abstract: Separation matrices useful in the formation of solid-state mm- to cm-scale devices for the rapid, high-resolution separation of single-stranded DNA ladder bands generated by the Sanger dideoxy- or Maxam/Gilbert chemical DNA sequencing procedures are formed from a solid support (1) having a plurality of posts (4) disposed on a first major surface thereof to form an obstacle course of posts (4) and pores (5). The posts are arranged in a regular X, Y array and are separated one from another by a distance of 100 nm or less, preferably 10 to 30 nm, and are optionally separated into lanes 2. The separation matrix can be manufactured by first forming a mold, preferably a reusable mold using lithography techniques. The mold is the reverse of the desired pattern of posts and pores of the obstacle course, and is used for casting the obstacle course. The cast obstacle course is then fused to a solid support and separated from the mold. Alternatively, the separation matrix can be formed from a polymer which undergoes specific and quantifiable swelling in the presence of a selected chemical compound. In this case, the matrix is cast on a mold in a conventional manner with a spacing between posts greater than the desired final spacing of 100 nm or less. For use, a buffer solution saturated with the specific chemical agent that controls swelling is added, causing the posts to swell to a defined amount to achieve the desired separation.

Title: Mammalian pro-protein converting enzyme
Inventor: CHRETIEN MICHEL
IPC: C12N15/57
Filed: 1996-08-02
Abstract: This invention relates to a novel and seventh member of the subtilisin-kexin family isolated from rat, which has been named rPC7. The rat spleen cDNA has been totally sequenced. A shorter DNA sequence has been obtained for human, which corresponds to a portion of the catalytic region of a human pro-hormone convertase corresponding to the rat pro-hormone convertase. PC7 clearly distinguishes from the other mammalian members of the subtilisin-kexin family. Its tissue distribution is ubiquitous, but its presence is particularly remarkable in lymphoid tissues. It is present in LoVo cells that are able to cleave the HIV gp160 protein into active gp120/gp41 proteins and that are deficient in other effective pro-hormone convertases known up to date. It is proposed that PC7 is a good candidate as a maturation enzyme responsible for the conversion of HIV gp160 protein in target CD+4 cells. Therefore, silencing the expression of PC7 would lead to the inhibition of the activation of gp160.

Patent CA-2233880-A1 (CA)
Title: Verdet constant temperature-compensated current sensor
Inventor: MACDOUGALL TREVOR W
IPC: G01R19/00
Filed: 1996-07-22
Abstract: A fiber optic, Faraday-effect current sensor (optical current transducer) which has improved temperature sensitivity due to compensation for temperature-induced variations of the Verdet constant. Fiber optic sensing coils can exhibit shifts in their bias angle due to a number of reasons, including physical rotation of the fibers, an apparent circular birefringence attributable to the sensing coil shape (Berry's phase), circular birefringence in the sensing fiber, or a DC magnetic field or current. The present invention takes advantage of the change in bias angle by identifying a preferred channel from the two sensing axes of the output fiber, based on the manner in which these axes respond to the change in bias angle. One of the axes will exhibit a change in sensitivity that exacerbates the change in sensitivity due to the Verdet constant, while the other channel will exhibit a change that complements, or compensates for, the change in sensitivity due to the Verdet constant. Once the preferred channel is identified, a polarizing fiber is attached to the output of the sensing coil, aligned to transmit the preferred channel to the optical detector.
