Inventor: KRAMER HY
IPC: H02G3/08
Filed: 1995-08-28
Abstract: The present invention relates to a new device for protecting wires and tubes that must be placed through the apertures in building panels or studs madeof steel or the like. The protection device disclosed herein comprises a single piece, plastic body having a wall surface which is bowed on opposing sides and flanged along its periphery. On opposing sides of the outer surface of the body's wall are arranged one or more protruding, angled pins or male nubs which securely hold, in the gap formed between the wall flange and the male nubs, the opposing rims of an aperture in a metal stud that this device is designed to be securely attached to. The body of this device can be of any size or shape, including but not limited to square, rectangular, oval or cathedral shaped. Due to its elasticity and larger than aperture size, this device can be pinched in along the opposing bowed sides of the body's wall and upon release an outward pressure is achieved against the rims of the stud aperture. The design of the protruding male nubs in relation to the wall flange allows this device to remainfirmly attached to the aperture once it is attached thereto.

Title: Method for screening for receptor agonists
Inventor: MCDONNELL DONALD P
IPC: C12Q1/68
Filed: 1994-04-06
Abstract: Method for assay for a receptor agonist. The method includes the steps of: providing nucleic acid encoding a receptor having a first TAF region able to activate transcription from a promotor, and a second TAF region mutated to have the functional context of the second TAF region, but not able on its own to activate transcription of the promoter. The nucleic acid is provided within a cell unable to exhibit transcription from the promoter in the presence of the second TAF region alone, but able to exhibit transcription from the promoter in the presence of the first TAF region. The cell further includes a reporter construct containing the promoter. The reporter construct is transcribed when the promoter is activated in the presence of the first TAF region. The method further includes contacting the cell with a potential agonist, under conditions in which contact of the cell with a known agonist of the receptor causes transcription from the promoter, and increases the level of the product of the reporter construct. Finally, the method involves measuring the level of increase of the product of the reporter construct as an indication of the agonist activity of the potential agonist.

Title: Transponder system for the remote communication of a physical condition
Inventor: LOWE PETER R
IPC: G08C17/02
Filed: 1996-05-16
Abstract: A transponder communicate information on a physical condition to a remote location, without the need for a lo-cal power supply or any wire or optical communications with the remote location, by detecting the physical condition and encoding information on the condition into a reprogram-mable portion of the transponder memory for transmission in response to an interrogation signal. The encoder is pref-erably formed from an oscillator that provides an output signal whose  frequency is a function of the information provided by the detector, and a counter that accumulates a count which is a function of the oscillator frequency, with the counter programming the memory in accordance with its accumulated count. A variable capacitor, resistor or in-ductor is preferably used to detect the physical condition and vary the oscillator's output frequency. A bubble wrap-type variable capacitor is particularly useful for monitor-ing the quantity of air within a tire.

Abstract: An electronic controller for controlling a trolley pole switch is disclosed.   The trolley pole switch switches the path of travel that an energy collector of a trolley pole takes through the  trolley  pole  switch  at  a junction of  power conduits diverging from the trolley pole switch.  The electronic trolley pole switch controller includes a signal processing device and a power controlling device employed in tandem to control the frog solenoids of a trolley pole switch.  The signal processing device detects and processes a plurality of modulated signals.          Each modulated signal represents a request to switch the path of travel that the energy collector takes through the trolley pole switch to a desired one of the power conduits diverging therefrom.  In response to each modulated signal, the signal processing device generates an intermediate command signal indicative of a command to supply power to the appropriate frog solenoid that effects the switch in the path of travel through the trolley pole switch to the desired power conduit.   The power controlling device receives the intermediate command signal  from the  signal processing device  and in response thereto  supplies  power  to  that  frog  solenoid.   The  frog solenoid energizes and therethrough compels the trolley pole switch to switch the path of travel that the energy collector will take through the trolley pole switch to the desired power conduit.

Title: Quasiturbine (qurbine) zero vibration - continuous combustion rotary engine, compressor and pump
Inventor: SAINT-HILAIRE ROXAN
IPC: F02B53/00
Filed: 1996-12-12
Abstract: While most rotary engines use the principle of volume variation between a curve and a moving cord of fixed length, this new engine concept uses a four degrees of freedom X, Y, .theta., .PHI. rotor, confined inside an internal housing contour wall, and does not require a central power shaft or support. The invention is an assembly of four carriages supporting the ends pivots of four pivoting blades forming a variable-shape rotor. This rotor rolls just like a roller bearing un the surface of an internal housing contour wall shaped like a skating rink. During the rotation, the rotor pivoting blades align alternatively in a lozenge and a square configuration. All ports are radial in the housing and/or axial on the lateral side covers. Since the compression and expansion strokes start and end simultaneously, an ignition flame transfer slot is used to maintain a continuous combustion while four strokes are completed in every rotation. A  central power shaft is not needed for the engine to operate, but can be added and driven by the blades, through mechanical coupling arms. The rotary engine incorporates few parts, does not need a crankshaft or a flywheel, and can be made strong enough to meet the criteria of photo-detonation and direct hydrogen combustion.

Patent CA-2193594-A1 (CA)
Inventor: FREDERIC ALAIN
IPC: H04N1/409
Filed: 1996-12-20
Abstract: The process provides modification of the resolution of an image obtained by digitising a real image which consists of a given number of pixels of measuring intensity. The process includes investigation and isolation of the contours of the digitised image, and creation of supplementary pixels by interpolation of the intensities of the original pixels situated on the same side of the contour, providing an image of modified resolution. The location of the contours is effected by marking, for each of the neighbouring pixels, the intensity transitions which represent a gradient which exceeds a given threshold. Before the interpolation procedure, the intensities of the original pixels are substituted by weighted values which are a function of the intensities of pixels which are near to the pixel of intensity to be weighted. Weighting is achieved by application of a matrix processing technique.
