Patent CA-2095761-A1 (CA)
Inventor: GROPPER DANIEL R
IPC: E04H12/22
Filed: 1993-05-07
Abstract: This invention relates to a portable, easy-to-put-together, strong, durable mast support system for use in field operations where an antenna mast, or other similar mast, needs to be safely and quickly assembled, raised and supported.  The mast support system is comprised of few pieces which stack in a compact longitudinal bundle for easy transportation to or from a site of use or for storage.  When packed for shipment, the entire assembly may easily be placed on the top of a car or other vehicle.  The mast support system is assembled through use of slideably interlocking pieces with hitch pins or clips.  No special tools are required.  The mast support system features a rotatable mast base alignment and support receptacle to enable one person to safely raise and lower a long mast after an antenna or other device has been safely affixed to the top of the mast when the mast is still at a safe horizontal ground-level position.      The primary anticipated use for the mast support system is when free-standing quick setup masts are required, is either an emergency or permanent installation.  The system may be used in backyards, driveways, fields, parking lots, and on platforms or rooftops, or in other suitable areas.

Patent CA-2104500-A1 (CA)
Inventor: CONACHEN JAMES A
IPC: B27F5/12
Filed: 1993-08-20
Abstract: Abstract Horizontal motorized drive rods in an upright rectangular frame control the movement of vertical guide rods in the X direction of the frame.  Motorized guide rods move a router on a movable mount along the Y direction.  A plungeable router, spring-mounted on the guide rods, is moved adjustably into the plane in the Z direction.  The router removes glazing from a window sash and cuts deeper into the rabbit joint of the sash to allow double pane glass to be inserted into the sash.  A rotary saw, with blade depth adjustment is swivel mounted to another vertical guide for cutting a slot in both vertical and horizontal rabbit joints to receive glazing beads.  Pins rigidly mounted in front of and behind the cutting edges of the rotary saw blade act as guides and stops for the saw.  Horizontal threaded rods with opposing right and left threads on either side of the center of the horizontal rod forms a centering device.  A pair of depressable spring-loaded stops are equally spaced from the center of the rod, and a crank moves the stops reversibly.          Sashes are centrally mounted on the frame using a sash centering device.  A rotary saw slidably mounted on a vertical guide is positioned by a guide centering device.  Equal amounts are out off each side of a sash using a rotary saw.  A spring-loaded pulley or counterweight is strung from the top of the vertical bar and connoted to the cutting tools to help support them.  The frame is adjustable to be mounted on various sized window frames or to allow sashes of various sizes and shapes to be mounted on the frame between clamp members on the frame.

Title: Container transporter
Inventor: SIMPSON CLARK
IPC: B66F9/08
Filed: 1992-02-27
Abstract: A self-propelled, counterbalanced, container (52) transporter has a frame (62), a counterweight (60) supported at the rear, an elevating upright (29), carriage pick-up and lift frame assembly (40) for lifting, transporting and stacking containers (52) at the front. The frame (62) has a tower structure (66) supporting a cab (16) having a wide angle front window area (22) that partially wraps around the operator's station to permit a horizontal line of sight to the maximum extension of the lift frame (40) and is sloped back to afford high angle vision to the maximum vertical extension of the upright for high stacking containers (52). The tower structure (66) is positioned rearwardly of the center, and projects upwardly to a height that provides an elevated line of sight from the cab (16) through the upright. Engine exhaust gases are routed to the front and out through the top of the upright (29) thereby reducing noise and exhaust emission levels in the cab (16).  A hydraulic circuit (105, 107, 108) is phased to deliver lifting pressure according to the lifted weight and engine speed matching loads with engine torque thereby increasing productivity by achieving higher lift speeds for light or empty containers (52).

Patent CA-2108957-A1 (CA)
Inventor: SKUDERA WILLIAM J JR
IPC: H04B1/10
Filed: 1993-10-21
Abstract: Two wide dynamic range detection circuits are disclosed, which are capable of detecting low-level desired signals in the presence of nearby strong interfering signals.          Each circuit includes an attenuator scheme for attenuating the interfering signal while passing the desired signal.  The first attenuator scheme uses a YIG filter in combination with an automatic gate arrangement.  The second attenuator scheme uses a two-channel arrangement.  The first channel uses a chirp-Z processor to derive a pulse-type transform signal in response to the strong interference signal.  The second channel includes a YIG filter followed by a programmable notch filter which is controlled by the interference-signal pulse from the first channel.  Following the programmable notch filter in the second channel is a chirp-Z processor followed by a gate arrangement wherein the gates are switched "OFF" under control of the interference-signal pulse from the first channel.
