Patent CA-2047333-C (CA)
Title: Catheter with needle guard
Inventor: DUCHARME LEONARD C
IPC: A61M5/32
Filed: 1991-07-18
Granted: 2002-12-10
Abstract: A catheter device is described with a safety needle guard that covers and protects the needle after use of the device. A sheath protects the user prior to introduction by locking against the needle housing. The device includes a semi-tubular needle housing containing a flash chamber with a hollow needle extending from the distal end of the flash chamber. A tubular needle guard concentrically fits and slides within the needle housing.      The needle guard has a longitudinal slot through which the mounting base of the flash chamber passes as the guard slides within the housing, and has an extension which makes its use more facile. The top of the semi-tubular housing is open so that a user may access the top of the tubular needle guard with a finger to urge the needle guard to an extended position from the distal end of the housing and in a surrounding position about the needle.      As the needle guard attains its fully extended position about the needle, it locks in place in the needle housing.

Filed: 1991-08-08
Granted: 1996-08-27
Abstract: A coin selector includes a single coin passage and a single  coin  rolling-down  passage.   The  coin  passage  is equipped with coin discriminating means so as to discrimin-ate whether a coin inserted through a coin insert slit is a true coin or a false coin, and moreover, discriminate the kind of the coin which has been recognized as a true coin.          On the other hand, the coin rolling-down passage is equipped with coin distributing means so as to selectively distribute the true coin conveyed from the coin passage depending on the kind of each coin.  Conclusively, the coin selector is constructed in a very compact configuration.

Granted: 1998-09-15
Abstract: A frame  support  holds  an  extendable  and retractable cylinder on which a tile engaging device is mounted.    A vibrator is combined with the tile engaging device.   In operation, when a tile is to be tested  for  adhesion  on  its  base  and  expected life-span  the  frame  support  is  placed on a tile surface,   the  cylinder  is  extended with  the  tile engaging device against a selected tile.   When the tile is engaged, vibration thereto is initiated for a predetermined time and at a predetermined rate.   The cylinder is retracted and the force used to pull the tile is an indication of the strength of the bond between the tile and the adhesive and between the substrate and the adhesive,  so that the life-span of the laid tile can be determined based on the measured force which is used to pull the tile.

Abstract: A multiple beam antenna system may be constructed for reducing a spillover loss in efficiency, improving beam crossover, and reducing undesired sidelobes by the addition of three dielectric lenses between a feed horn cluster connected to a beam forming network and an objective collimator.  The system includes a beam forming network including a plurality of feed horns in a feed horn cluster, an objective, and an imaging lens having a lateral magnification less than unity for focusing a reduced image of the feed horn cluster at a predetermined point in space.

Abstract: Embedded coding within coded speech signals of a signal flow having a lower bit rate is provided for signals produced by analysis-by-synthesis coding systems such as CELP.   The excitation chosen for coding at a transmitter  has   contributions   provided   by   several excitation  branches, a  first  of  which  provides  a contribution allowing transmission at a minimum bit rate, whilst the other branches provide contributions permitting successively higher bit rates.   During coding, only the excitation from the first branches is filtered taking into account  the  coding  of  previous   frames,   and  the contributions from different branches are inserted into different distinguishable packets.   During transmission through  a  network,  any  necessary  packet  dropping  is implemented first in relation to packets containing the contribution permitting the highest bit rate, and then on packets containing contribution necessary for successively lower bit rates, but always leaving the packets containing the contribution from the first branch.  During reception, the  excitation  submitted  to  the  filter  for  decoding includes  contributions  from  a  first  excitation  branch corresponding to the first branch at the transmitting, and from  other  branches  corresponding  to  contributions represented in the received packets if received at a rate permitting more than the minimum bit rate.  Again, only the filtering of the continuation from the first excitation branch taken into account the results of filtering of preceding claims.

Abstract: Intracavity Raman lasers comprising a pump resonator and a Raman resonator that eliminates alignment problems associated with multi-mirror intracavity lasers. The pump resonators include a laser rod and a pump source.  In one embodiment, a first retroreflector is disposed at one end of the pump resonator, and an output mirror is disposed at an opposite end thereof.  A Q-switch, a dichroic mirror, and a prism are disposed between the laser rod and the output mirror.  The pump resonator radiates pump energy at a first wavelength (1.06 µm) between the first retroreflector and the output mirror.  The Raman resonator includes a Raman gas cell having first and second lenses disposed on opposite ends thereof for focusing laser energy into the Raman cell, and a second retroreflector that forms one end of the Raman resonator. The output mirror forms an opposite end of the cell, and the dichroic mirror and the prism are disposed between the second retroreflector and the first lens.  The Raman resonator radiates Raman laser energy at a second wavelength (1.54 µm) between the second retroreflector and the output mirror.  A second embodiment eliminates the the second retroreflector and dichroic mirror and moves the position of the Q-switch to a point between the retroreflector and the laser rod.  The present lasers are extremely insensi-tive to misalignment and have eyesafe output energy and acceptable beam divergence. The present lasers, in a production design, may be mechanically toleranced so that no optical alignment is necessary.  Due to their self-aligning nature, the present lasers have fewer components and operate at higher pulse repetition frequencies than conventional multi-mirror intracavity lasers.

Title: Tree trunk surround
Inventor: BASLEY MICHAEL BYRN
IPC: A01G13/10
Filed: 1994-06-30
Granted: 1998-06-23
Abstract: A tree trunk surround including the use of re-usable tire casings, particularly the tire walls which are severed into truncated wedges with the narrower or rim edge affixed to a flexible or resilient band which stretches to allow unhindered growth of the tree and which has latching means at opposite ends whereby the band may be fixedly located as a loop around the trunk of the tree.  Preferably, there is a light impervious sheath, commonly known as landscaping fabric, underlaying the inside surface of the band and spatially disposed truncated wedges so that light will not penetrate the surround when engaged about the tree.  This inhibits growth of weeds and the like.  The outside tire casings provide a barrier so that when trimming takes place about the tree, as by string weedcutters and lawnmowers, the bark of the tree is not bruised by these machines.
