Abstract: ABRÉGÉ DESCRIPTIF Dispositif de réglage à distance d'un ensemble d'émetteursrécepteurs, notamment pour la reconfiguration des stations de base d'un réseau de radiotéléphonie cellulaire Ce dispositif comporte: -des moyens de mesure d'un paramètre radioélectrique du filtre (11), ce paramètre étant un paramètre caractéristique du désalignement de ce filtre par rapport à une réponse fréquentielle ou temporelle de consigne, et -des moyens pour modifier le réglage dudit filtre dans un sens réduisant ce désalignement, ces moyens étant des moyens asservis sur la mesure dudit paramètre. Ledit paramètre radioélectrique peut notamment être le rapport d'ondes stationnaires d'entrée du filtre, la fonction de transfert ou la réponse impulsionnelle du filtre, ou encore le taux de distorsiuon du signal transmis. Pour la mesure du paramètre radioélectrique, on peut notamment appliquer au filtre une série de fréquences pures localisées dans la bande sur laquelle le filtre doit être réglé, et/ou sur les flancs de cette bande puis régler le filtre par minimisation d'une fonction d'écart des valeurs du paramètre radioélectrique mesurées auxdites fréquences pures par rapport à des valeurs correspondantes idéales mémorisées, et/ou par symétrisation des valeurs du paramètre radioélectrique mesurées auxdites fréquences pures par rapport à au moins une fréquence centrale donnée.

Patent CA-2054607-A1 (CA)
IPC: C12N13/00
Filed: 1991-10-31
Abstract: A transformed plant of Gramineae is prepared by culturing an anther of Gramineae in a callus induction medium and, at a stage immediately before the microspore       begins to cause division or during the initial division, transducing a genetic substance into the microspore cell through a pore formed by a laser pulse thereby to express genetic information of the genetic substance.          According to the present invention, it is unnecessary to prepare protoplast and therefore, time and operations for transformation can be greatly reduced.  Since haploid cells are transformed, the character transduced is conveyed without separating at a later generation.  In addition, difficulties in experiments between species and strains are minimized so that it is easy to apply the present invention to practical species.  According to the present invention, large pores can be formed as compared to the electroporation method so that DNA or substances having a large molecular weight can be introduced.

Title: Chain saw guide bar
Inventor: OKAMOTO KENJI
IPC: B27B17/02
Filed: 1992-02-28
Abstract: ABSTRACT OF THE DISCLOSURE    This disclosure relates to a guide bar for a chain saw, wherein easily formed multiple through-holes are provided in a guide bar for the purpose of reducing the weight of the guide bar. A synthetic resin material fills the through-holes and is prevented from falling out of the guide bar by locking parts at the margins of the holes.  In the process of making the guide bar, after multiple through-holes 2 are provided in a guide bar, the areas around the through-holes 2 are compressed so that they undergo plastic deformation and form the locking parts 5.  Then the synthetic resin material 7 is injected into these through-holes 2 and allowed to harden so that it becomes an integrated construction with the guide bar 1, and the synthetic resin material 7 is securely locked in place by the locking parts.

Title: Method and apparatus for sensing proximity of an object using near-fieldeffects
Inventor: WOLFF GEORGE D
IPC: G01D5/20
Filed: 1992-05-06
Abstract: ABSTRACT OF THE INVENTION    A method and apparatus for sensing proximity of an object using near-field effects.  Modulated radio frequency energy is fed to an antenna.  The antenna radiates this modulated radio frequency energy to charge the surface of an object.  When the position of the object changes, the impedance of the antenna due to near-field effects changes.  This impedance change is detected to provide an indication of the object's movement.  The sensing device may be packaged to be inserted into a wall to provide a sensor having a leak-free seal.

Patent CA-2074396-A1 (CA)
Title: Portable paper trim removal system with trim rewinder and dust vacuum
Inventor: FREEMAN ROSS A
IPC: B26D7/18
Filed: 1992-07-22
Abstract: ABSTRACT OF THE DISCLOSURE    A system for collecting paper trim and dust automates and simplifies the removal and disposal of trim.  The system includes a funnel receiving the paper trim from an automatic trimmer, a drum and rewinder for winding the paper trim into a bale, and a dust trap for sucking dust from the drum and funnel into a dust bin.  As the trim is baled, the rewinder drags the paper bale against the side of the drum. This drag compacts the bale and increases the load on the rewinder.  As the drag load on the rewinder increases, the rewinder is moved radially towards the center of the drum to increase the distance between the rewinder and the drum wall.  A current sensing circuit triggers the radial movement of the rewinder when the current load on the rewinder motor exceeds a threshold limit.  This radial movement reduces the drag on the rewinder.  When the rewinder reaches the center of the drum and the trim bale fills the drum, the rewinder is stopped and the trim bale removed.

Title: Compositions to improve survival of biological materials
Inventor: RUBINSKY BORIS
IPC: C12N5/02
Filed: 1992-01-17
Abstract: The present invention relates to aqueous compositions of substances, such as organic molecules, which are useful to protect and preserve viable plant or animal cell membrane and tissue exposed to hypothermal and hyperthermal temperatures or nonphysiological chemical conditions, and to modify the freezing process of liquids in biological plant or animal cells or tissue. More specifically, the present invention relates to the use of antifreeze polypeptide or antifreeze glycopeptide which is derived, for example, from the fluid or serum of Artic and Antarctic fish. Preferred antifreeze compounds are related to those polypeptides having multiple alanine-alanine-threonine- or alanine-alanine-alanine- segments.  In some embodiments, a pendant sugar group is covalently attached to each threonine moiety. An aqueous solution of the peptide or glycopeptide is contacted with cells ova, sperm, oocytes, embryos, tissue, an organ, or a whole living plant or animal. The cells, tissue, organ or plant or animal is then carefully cooled and/or frozen at 0 ·C or below (in some cases to -196 ·C or to 4 K) and held at the low freezing (or vitrification) temperatures. The ice forms, if at all primarily along the c-axis with the result that cell membranes are not disrupted and the cells are not dehydrated. The cells, tissue, whole plant or organ or animal are carefully thawed, and all are found to be viable. The preserved organs are particularly useful transplant organs for a human being.
