Title: Fire simulator for fire fighter training
Inventor: CROSS DAVID
IPC: G09B9/00
Filed: 1993-04-01
Abstract: ABSTRACT           A conflagration simulator system for fire fighting training comprises a portable flame generator with a shallow water bath to which combustible liquid or gaseous fuel is admitted below the water surface, and passes upwardly in dis-persed relation therethrough, to combust in the atmosphere, as a wild-fire.  An unquenchable pilot flame with independent fuel and air supplies and independently energized low voltage electronic  ignition  has  an  extended  flame  tube  with  an elongated, two axis exit port, to ensure persistent ignition conditions over an extended zone of the bath.   The system includes a separately portable, wheeled control center, in-cluding gas and air supplies with associated control valves, an electrical power source, and connection hoses permitting rapid connection of the control center to the flame genera-tor,  and an electrical hard wired or radio control with a dead-man energizing switch, to enable instantaneous shut-down of the system.

Patent CA-2112267-A1 (CA)
Title: Incinerator, particularly for used medical needles
Inventor: GREVILLE PETER
IPC: A61M5/32
Filed: 1992-06-24
Abstract: An incinerator for use in incinerating substantially hollow articles is provided with crimping means (31, 36) adapted to plastically deform a portion of the article. Typically the article comprises an elongate hollow medical needle (64) and therefore the incinerator typically includes a pair of spaced electrically conductive contacts (25/26, 27/11) defining a gap across which an electrical potential difference is set up. When the needle is brought into contact with the pair of contacts, the portion of the needle bridging the gap is incinerated. The crimping means (31, 36) acts to provide a substantially sealed end or termination to the portion of the needle which is not incinerated. Potentially harmful fluids which may be present in the remaining portion of the needle or the syringe to which the needle is attached are thereby effectively sealed in the needle and syringe.

Patent CA-2114932-A1 (CA)
Inventor: CARPENTER JAMES B
IPC: G02B6/36
Filed: 1992-07-27
Abstract: 2114932 9305419 PCTABS00020 An optical fiber splice element (10) comprising a sheet (12) of ductile material having a novel focus hinge defining first and second legs, each of the legs (18, 20) having a V-groove therein for receiving the optical fibers. The focus hinge, comprising a groove on one side of the sheet, a notch on the other side of the sheet aligned with the groove, and a convex hinge web, provides precise registration of the V-grooves (22, 24) when the sheet (12) is folded; this in turn leads to improved alignment of the fibers.  The V-grooves (22, 24) also have a novel angular geometry which optimizes the clamping forces, resulting in lower insertion loss.  The interior angle of the V-grooves is smaller than the optimum angle whereby, when the fiber is clamped and portions of the V-groove surfaces are deformed, the V-groove has an effective angle which is approximately equal to the optimum angle.

Patent CA-2116898-A1 (CA)
Inventor: DEURICHEN JG HANS
IPC: F24B1/188
Filed: 1994-03-03
Abstract: There is disclosed a heat exchanger for use in a heating unit and more particularly for use in a fireplace.   The heat exchanger comprises a hollow body of pleated or corrugated metal material to enhance the heat exchanger from a high concentration within the body to a lower concentration exteriorly thereof.  The use of a corrugated metal material avoids mechanical fatigue since the corrugation permits easy contraction and expansion which normally occurs during heating and cooling of the heat exchanger.  The result is a long-lasting highly efficient heat exchanger.

Patent CA-2121529-A1 (CA)
Inventor: TANAKA YASUSHI
IPC: H04N5/44
Filed: 1994-04-18
Abstract: To provide a picture intermediate frequency circuit capable of preventing the occurrence of intermodulation beats in a strong electrical field, without affecting in any way the original picture signal. A picture intermediate frequency signal output from the tuner 2 is supplied to a pre-amplifier 5 via an adjacent sound trap circuit 3, and a picture trap circuit 11 and 12, both of which are connected in series. Trap circuits 11 and 12 each have an attenuation point in the upper and lower frequency components equivalent to the frequency difference of the adjacent picture signal frequency with respect to the picture intermediate frequency signal, and trap the ~ 6MHz frequency components of the picture intermediate frequency signal. This allows the trap circuits 11 and 12 to previously remove unnecessary adjacent picture signals before they reach the pre-amplifier 5. As a result, the high frequency component generated in the non-linear region of the pre-amplifier 5 in a strong electrical field is prevented from interfering with the high frequency component of the unnecessary adjacent picture signals to produce cross-modulation signals, thus eliminating the occurrence of cross-modulation beats.

Patent CA-2126604-A1 (CA)
Title: Method and device for estimating transmitted signals in a receiver in digital signal transmission operations
Inventor: JAMAL KARIM
IPC: H04B7/005
Filed: 1994-06-23
Abstract: In a digital signal transmission system, a receiver (14) receives a signal (R(T)), wherein the signal bandwidth of the system exceeds the system symbol rate. A correlation and sampling circuit (15) receives a baseband signal (y(T)), samples (21) the signal eight times (y(k/8)) per symbol time (TS), correlates (23), generates a channel estimate (~F) and down-samples the sampled signal (y(k/8) ) to form an observed signal (y (k/2)). This signal is filtered in a prefilter (26), whose output is sampled at symbol rate (27, TS/1) and the obtained signal (z(k)) is delivered to a channel equalizer (17) which performs a viterbi algorithm with non-quadratic metric calculation and generates estimated symbols (~D(k)).      A channel estimation filter (31) receives a symbol sequence which contains alternate zero-value symbols (.OMEGA.) and the estimated symbols (~D(k)) and generates an estimated signal (~(k/2)). An error signal (e(k/2)=y(k/2)-~(k/2)) is generated and used to adapt (34) the channel estimate (~(k/2)) and also to generate (35) weight factors (.alpha.(k/2)). The coefficients (~(k/2)) of the prefilter (26) are generated as a function of the channel estimate (~(k/2)) and the weight factors (.alpha.(k/2)).      Coefficients are generated in a metric calculation filter (39, ~(k)) by convoluting the channel estimate (~(k/2)) with the prefilter (~(k/2)) and are used to generate the estimated symbols (~D(k)). The transmisson channel, excluding the prefilter (26), is estimated explicitly so as to enable fast channel changes to be followed. The use of the weight factors (.alpha.(k/2)) enables a short channel estimate to be used. The insertion of the zero-value symbols (.OMEGA.) simplifies adaptation (34) of the channel estimate (~(k/2)).

IPC: E05C1/10
Filed: 1994-10-25
Abstract: A safety gate that has a continuously adjustable width for insertion across a lateral opening such as a doorway. The gate has a generally U-shaped gate frame including two tubular frame members that are slidably connected in a telescoping relationship. A latch is operable to displace the telescoping portions by a pre-selected displacement relative to each other, so that part of the tubes are deflected and the gate frame applies an outward lateral force to the doorway opening sides to retain the gate across the opening. The gate includes a walk-through door with a door latch for latching the door closed and an indicator for indicating when it is not fully closed and latched. A force-distribution bar on at least one side of the gate distributes the force from that side of the gate so that it is applied at two points on that side of the doorway opening.
