Title: Isometric exercising apparatus
Inventor: DRISCOLL LARRY J
IPC: A63B23/12
Filed: 1995-03-13
Abstract: An exercising apparatus that is comprised of a base, to which are attached, two rear upright supports and two front supports inclined to the rear. These supports are then connected at the top. The exercising device itself consists of two mechanisms, the ratchets being the central components, and two adjustable arms which are connected by a bar against which the various exercises are performed. This device, due to it's unique configuration, provides a comprehensive isometric exercise regiment for the entire body. Isometric exercises differs from the more commonly used isotonic exercises in that the muscles being exercised contract against a static force. No movement is involved.
Patent CA-2145126-A1 (CA)
Title: Pipe Laying System and Method
Inventor: FULLER FRANK E
IPC: E03F3/06
Filed: 1995-03-21
Abstract: A system  for  simultaneously lining and  cleaning an existing sewer pipe, and for laying horizontal pipe without digging a trench, includes a planetary gear assembly mounted on a drilling rig.  A liner pipe or outer pipe which is to be laid underground is placed over an inner auger,  with the forward end of the liner pipe located behind the auger drill bit.  The opposite end of the auger is attached to the sun gear of the planetary gear assembly; and the outer pipe is secured to the ring gear of the assembly.   The auger is rotated in one direction, causing the outer pipe to rotate in the other direction;  and the pipe and auger are pushed simultaneously through the pipe to be lined or through the soil.  Once a section of auger and liner pipe have been pushed in place, the planetary gear assembly is disconnected from the auger and the liner pipe, new sections of auger and liner pipe are connected to the existing sections at one end, and to the planetary gear assembly at the other end.   The process is repeated until the desired length of pipe is inserted into the ground.  After completion of insertion of the pipe, the pipe is disconnected from the planetary gear assembly and the auger is withdrawn through the pipe for use with a subsequent installation.

Title: T-bar clip
Inventor: MCINNIS SHAUN
IPC: E04B9/12
Filed: 1995-05-24
Abstract: A clip for connecting T-bar members of a suspended ceiling which may be connectçd to the end of a T-bar is formed from planar steel, with a hole for insertion of a rivet, a thumb rest for rotating the clip from a disengaged position in which the clip does not extend beyond the end of the T-bar to which the clip is attached to a position in which the forward end of the clip extends through a vertical slit in the web of a perpendicular adjacent T-bar. The clip has a spring loaded lobe which when inserted through the slit of the perpendicular T-bar, locks the clip in the slit. The clip may be used to join members of a ceiling grid and may be disengaged from a perpendicular T-bar without damage to either T-bar, or to the clip itself.

Title: Turbocharger Turbine Wheel and Shaft Assembly
Inventor: BEDNARZ STEPHEN MICHAEL
IPC: F01D5/02
Filed: 1995-08-28
Abstract: A turbine wheel for a turbocharger or the like is mounted to an impeller shaft and optionally an additional drive shaft by annular rows of coupling teeth preferably of the CurvicTM coupling type having radially and rotationally locking convex sided and concave sided interlocking teeth.  Flexible webs connecting coupling rings on the turbine allow thermo and mechanical growth of the turbine wheel without excessive deflection of the coupling rings and the associated shaft flanges.  A single central stud threaded into one of the shafts and retained by a bolt against the other maintains the components in assembly with the coupling teeth fully engaged.  A radial slot formed in the coupling flange for one of the shafts prevents thermal distortion of the flange from substantially affecting an adjacent thrust bearing portion of the flange.  The arrangement simplifies rotor assembly and avoids the need for rebalancing after disassembly and reassembly.  The full width of the coupling teeth are available for the transmission of torque and radial alignment forces.

IPC: B01J19/24
Filed: 1994-10-06
Abstract: A water sterilisation system comprises an electrostatic water treatment apparatus (10) having its outer duct (13) connected to an ultraviolet treatment apparatus (11). The outlet duct ( 14) of the ultraviolet water treatment apparatus (11) is connected to an apparatus (12) which aerates the treated water with ozone gas. The electrostatic field of the apparatus (10) varies along the axis of the flow duct, so as to increase the speed at which dissolved minerals precipitate out of solution.

IPC: B05B15/04
Filed: 1996-04-09
Abstract: Masking paper includes a black and white pattern formed thereon, preferably along at least one edge of the paper, with an area substantially adjacent a surface to be painted being masked using a patterned portion of the masking paper.  The masking paper may include an adhesive on its back side, i.e, the side opposite the black and white pattern, at least on the portion of the back side generally opposite the patterned portion of the masking paper.  Once properly masked, paint is applied to the surface to be painted with the painter running the paint pattern over a portion of the black and white pattern on the masking paper to gauge its coverage and/or color.  If an additional check is desired, another portion of the pattern may be checked in the same manner.  Since only the edges of the masking paper include the black and white pattern and since the black portion of the pattern does not cover even the patterned portions of the edges, light in a painting location is still enhanced using the masking paper of the present application.

The air guide wall eliminates reverse flow of the air in the casing.  The cavity has air guide holes on one side wall thereof and cavity air exhaust holes on the other wall thereof, so the air is directly introduced into the cavity.

Abstract: A ground fault circuit interrupter (GFCI) line cord plug utilizes an electronically latched relay, rather than a circuit breaker or other type of mechanical latching device, to interrupt the AC load power when a ground fault condition occurs. In order to reduce the size of the relay and minimize the cost and complexity of the GFCI plug, the fixed and movable relay contact structures are mounted directly to the circuit board which carries the remaining components of the GFCI circuit. In a preferred embodiment, the fixed relay contact structures are integral with the plug blades of the GFCI plug. The movable relay contact structures preferably comprise deflectable spring arms which are preloaded when the relay contacts are in the open position in order to control the contact gap, and which are deflected past the point of contact closure when the relay contacts are in the closed position in order to increase the closing force. The principal electrical components of the GFCI plug, including the relay contacts, relay coil and sensing transformer, are mounted on the circuit board in a generally tandem or in-line arrangement in order to minimize the dimensions of the plug.

Patent CA-2178778-A1 (CA)
Title: Fail-safe fluid transfer controller
Inventor: STEMPORZEWSKI FRANCIS V JR
IPC: B67D7/32
Filed: 1996-06-11
Abstract: A fail-safe fluid transfer control apparatus has full redundancy in the response to various inputs such as overfill probe signals, ground detection signals, and the like. Independent microprocessor controllers independently evaluate the inputs and each output control signals to close a respective relay when the inputs indicate that fluid transfer may commence. The relays are arranged in series such that both must be closed for a fluid transfer to commence. The control signals from each controller include a static signal and an alternating signal, both of which must be properly output to close its respective relay. Each controller monitors the state of each relay, and discontinues its control signals if either relay appears to be malfunctioning. Each controller runs an different, independently written firmware program to process the detected inputs to prevent a common firmware error. An optical bypass key replaces conventional mechanical keys and transmits an optically encoded signal to the controller for establishing a bypass condition. A preheating circuit is also provided for providing a dynamic voltage supply to standard thermistor probes which may be encountered.
