Patent CA-2216513-A1 (CA)
Inventor: JANSEN HUBERT
IPC: A61M5/31
Filed: 1997-09-26
Abstract: A lockable safety shield for a prefillable syringe is provided. The design of the lockable safety shield enhances pharmaceutical manufacturers' ease of assembling the various components as part of its filling or processing of the prefillable syringes in normal practice. A collar is attachable to the distal hub of the prefillable syringe. A safety shield is axially slidable over the collar between a retracted position, wherein the distal end of the piercing element associated with the prefillable syringe is exposed, and an extended position, wherein the safety shield is locked to the collar to protectively cover the distal end of the piercing element. The safety shield includes locking structure configured so that the shield, as supplied to the pharmaceutical manufacturer, can be easily fitted to the syringe. The locking structure includes at least one deflectable arm provided on the body of the shield. The deflectable arm includes a proximal end deflectable towards the interior of the shield. A stop member is provided on the interior of a shield in spaced relation to the proximal end of the deflectable arm. A ring is axially slidable over the shield to deflect the arm towards the interior of the shield to activate the locking structure. The safety shield is slid distally by an end user such that the collar is lockingly retained between the stop member and the proximal end of the deflectable arm. The collar, the stop member, and the deflectable arm may be configured to provide tactile as well as audible indication of locking to the end user.

Title: Remote operated logging system
Inventor: DEXTRAS KENNETH G
IPC: A01G23/00
Filed: 1998-10-23
Abstract: The invention relates to a system (and devices) for performing selective and unmanned aerial logging "off the sump"; thereby eliminating the need for clear cutting and most of the associated roads. The net result is a controlled harvest that leaves the remainder of the forest intact and undisturbed. This is accomplished by using an explosive method (and device) to launch a pre-trimmed tree trunk, with a rocket powered vehicle attached to it at the appropriate location, to a safe elevation above the tree line. Once this elevation is attained, the rocket powered vehicle kicks-in to support and carry the log to a predetermined location using a missile guidance system. Other devices are then deployed to control the rate of descent and landing of the vehicle and its cargo. The complete flight (from blast off to landing) is remote control operated.

Title: Portable instrument to determine concentration of afff in fresh and sea water solutions
Inventor: HAGGETT RANDALL D
IPC: G01N21/43
Filed: 1998-10-14
Abstract: A compact portable instrument for determining the percentage concentration of a material in a solution such as the amount of concentrate in an output from an Aqueous Film Forming Foam generator used to extinguish fires. The instrument comprises a refractive index sensor with a reflective type refractometer prism having a measuring surface in contact with liquids placed in a sample holder formed by an opening through a retainer plate. The measuring surface of the prism covers that opening and presses the retainer plate towards an outer surface of the instrument, that outer surface having entrance and exit ports for sample liquids at that opening. The refractometer senses the refractive index of liquid in the sample holder and, when properly calibrated, provides an output to a digital display that directly indicates the percentage concentration of material in the liquid. A small thin sample size of about 100 microliters provides rapid thermal stabilization of the sample liquid and allows the percentage concentration to be quickly and accurately determined.
