Patent CA-2136117-A1 (CA)
Title: Inertia hinge for seatback and armrest
Inventor: WHALEN JOHN F
IPC: B60N2/75
Filed: 1994-11-18
Abstract: An inertia sensitive hinge mechanism allows rotation of a first hinge member relative to a second hinge member about a pivot during normal use and prevents rotation about the pivot when predetermined deceleration forces are present. The inertia sensing latching assembly includes an inertial actuator operatively connected to and rotatable with respect to the second hinge member. The inertial actuator includes first and second cam surfaces and a wedging surface located therebetween. The inertial actuator has a center of gravity spaced from a center of rotation. A first positioning device connected to the first hinge member positions the inertial actuator by sliding engagement with the first cam surface as the first hinge member rotates in an opposite direction when the predetermined forces are not present. A second positioning device connected to the first hinge member positions the inertial actuator by sliding engagement with the second cam surface as the first hinge member further rotates in the opposite direction when the predetermined deceleration forces are not present. When the deceleration forces are present, the first hinge member initially rotates in the opposite direction, and the inertial actuator is positioned by the predetermined deceleration forces such that the wedging surface engages the second positioning device preventing further rotation of the first hinge member in the opposite direction.

Patent CA-2145833-A1 (CA)
Title: Induction of embryogenesis and generation of doubled plant haploids using microtubule inhibitors
Inventor: SIMMONDS DAINA H
IPC: C12N5/02
Filed: 1995-03-29
Abstract: Embryogenesis from plant microspores can be induced with a 24 h temperature treatment of 32.5°C. Continuous culture at 25°C  results in pollen development. However, in this study, microspore treatment by microtubule inhibitors, at the non-inductive temperature of 25°C, can induce embryogenesis, thus demonstrating that heat shock is not required for embryogenic induction. A great advantage in using microtubule inhibitors is that induction and chromosome doubling can occur simultaneously, thus generating doubled haploids, whereas heat induction generates haploids. Thus, the use of microtubule inhibitors will provide a simple one-step process to simultaneously induce embryogenesis and chromosome doubling for the production of fertile plants, thus providing minimal manipulation which will be very advantageous for genetic studies and plant breeding programs. As noted, heat shock induction induces haploids. Chromosome doubling can be induced by colchicine. However, the application of trifluralin to embryogenic microspore cultures to generate doubled haploid plants results in an improved recovery of fertile doubled haploid plants than previously shown in the prior art.

Title: Filter cleaning
Inventor: NEVILLE MARK DAVID
IPC: B01D65/02
Filed: 1995-05-26
Abstract: An  electrically  conducting  filter medium  (20)  is cleaned in situ by applying, at intervals, a brief voltage pulse between the medium (20) and a counter electrode (18) so the process liquid undergoes electrolysis.  The cleaning process is significantly improved by occasionally applying a voltage of reverse polarity.   For example a 5 second cleaning pulse making the filter medium (20) cathodic might be applied every quarter of an hour, and a reverse polarity pulse of similar duration applied every two hours.  This process can significantly increase permeation rates.

Abstract: A data recording and/or reproducing method for performing a trick play in a digital video tape recording and reproducing apparatus for recording and/or reproducing an advanced television (ATV) signal is performed such that the data area of a sync block each forming audio sector and video sector in a track is divided into a first area and a second area to record and reproduce normal-play data and trick-play data for a normal play and a trick play, respectively. The area corresponding to 5.6 Mbps is used for trick-play data in the case of an ATV signal and a separate data area for the error correction coding of a trick-play data is not necessary. Also, since trick plays of speeds of even-number times are available within the range of the maximum multiple speed, a diversity of speeds of a trick mode is allowed.

Title: Method and device for controlling the reflex response of the muscles of a living body joint
Inventor: BROSSARD ANDRE
IPC: A61H39/04
Filed: 1995-10-31
Abstract: To control the reflex response of a muscle or muscular group articulating a joint of a living body, the method and device apply an external pressure to the mechano-receptors guiding the natural reflex mechanism of  the  muscle  or muscular group.    The mechano-receptors include skin mechano-receptors and deeper  joint  mechano-receptors.    To  increase  the reflex response of the muscle or muscular group, a light pressure intensity  200 mmHg is applied to stimulate only the skin mechano-receptors and thereby increase the reflex response of the muscle or muscular group.  To inhibit the reflex response of the muscle or muscular group,  a high pressure intensity  400 mmHg is applied to stimulate the deeper joint mechano-receptors  such  as  the  Golgi  tendons  to thereby increase the reflex response of the muscle or muscular group.
