Title: Method and apparatus for ultrasonic leak location
Inventor: KUNZE ULRICH
IPC: G01M3/24
Filed: 1993-08-18
Abstract: Abstract of the Disclosure:          A method for ultrasonic leak location includes showing sound levels in a bar diagram at various locations along a measure-ment segment.   The measuring segment  is  divided into subsegments with intrinsically uniform damping.  Effective portions are obtained by multiplying the subsegments by the associated damping coefficient, and an effective portion is assigned to each of the subsegments.  Corresponding effective measuring positions are ascertained for the measuring loca-tions  within  the  effective  portions.   Respective logarithmized net sound levels are plotted through the ascertained effective measuring locations and two inclined straight lines are produced as a result.  An intersection of the straight lines in the bar diagram is ascertained for identifying a leak point.  An apparatus for ultrasonic leak location includes a number of ultrasound pickups being disposed at measuring locations along a measuring segment, a data processing computer, amplifiers and components forming an effective value.  The amplifiers and the components are connected between outputs of the ultrasound pickups and the data processing system.

Title: Faucet diverter valve
Inventor: PIPPEL BRADLEY J
IPC: E03B9/02
Filed: 1993-09-30
Abstract: A faucet diverter valve is disclosed having three positions for delivering a stream or spray of untreated water, or a flow of treated water. The position of the faucet diverter valve is selected by means of a single rotating handle. Rotation of the handle causes a valve spool to move axially within a manifold to bring fluid flow openings in the valve spool in and out of alignment with openings in the manifold. The valve spool carries seals which direct the flow of untreated water through a straight stream outlet, a spray outlet, or to a treatment loop in which untreated water passes through a treatment device, returns to the faucet diverter valve, and exits through a treated water outlet. The treatment loop return is sealed against dripping and the introduction of air by the valve spool.

Title: Computer workstation
Inventor: BALL DOUGLAS
IPC: A47B83/00
Filed: 1993-12-31
Abstract: An ergonomic workstation suitable  for  a user to perform a task on a computer.  The workstation comprises a planar desk surface for supporting the display screen and the keyboard unit of the computer.  A reclining chair is provided in front of the desk in which the user sits.          The  chair  is  mounted  on  a  rectilinear  track  for translational movement relative to the desk.  A foot rest under the desk maintains the feet of the user captive so that the user induces a translational movement of the chair upon tilting the chair,  i.e.  inclining the chair toward  or  away  from  the  vertical  position.   The translational component of the movement to which the chair is subjected at least partially counterbalances the shift of position of the upper part of the user's body that the tilting  component  generates.  As  a  result  of  this arrangement,  the  upper  part  of  the  user's  body  is maintained at the optimal position eyes/display screen and shoulders/keyboard.

Patent CA-2119718-A1 (CA)
Inventor: GREGOR PHILIP D
IPC: H05B41/38
Filed: 1994-03-23
Abstract: A method and circuit for providing stability during dimming of an electrodeless high intensity metal halide discharge lamp driven by a microwave source. Light from the lamp is rapidly dimmed to a low level in a stable manner while preventing the possibility of lamp extinction. Remote optical sensing of lamp light output is coupled with power control circuitry which modifies power delivered to the lamp based on the light response to wall defined pulses of power in the output of the microwave source.      Power delivered to the lamp is increased when the rate of light drop exceeds a predetermined rate and also, is controlled based on the overall light emission intensity. As a result, stable dimming is achieved regardless of the initial conditions of the discharge.      The dimming method disclosed is more forgiving of light-source-system manufacturing tolerances than is presently available using absolute light intensity control alone when source output power is limited.

Title: Edible bun having a compartmented central recess and a baking mold for producing same
Inventor: GROULX LINE
IPC: A21D13/32
Filed: 1994-08-01
Abstract: An edible bun having a substantially elongated configuration. The bun has a base wall, a pair of integrally extending side walls and a pair of integrally extending end walls. The base walls, the side walls and the end walls define an open top food receiving cavity. Each side wall has a lower section and an upper section. The thickness of the upper section is relatively smaller than the thickness of the corresponding lower section. The open-top food receiving cavity is thus generally divided into two superposed compartments. The lower compartment is typically adapted to receive a sausage while the upper compartment is adapted to receive conventional condiments. The upper peripheral edge of the upper section preferably has an inwardly oriented retaining lip. The upper sections of the side walls are bendable between an opened configuration wherein the retaining lips are spaced relatively to one another and a closed configuration wherein the retaining lips are adapted to prevent the condiments from spilling out of the bun. The present invention also proposes a baking mold for manufacturing the buns. The baking mold has a base portion provided with a set of spaced apart female mold recesses and a lid portion provided with a lid cover plate and a set of male shaping members. The male shaping members are adapted to be inserted inside the corresponding female mold recesses when the lid portion is superposed on the base portion. Each male shaping member and its corresponding female mold recess is adapted to create a mold cavity for forming a bun having a compartmented central food receiving cavity.

Filed: 1994-10-06
Abstract: ADJUSTABLE SLIP-FIT WELDING NOZZLE     Abstract of the Disclosure An adjustable slip-fit welding nozzle enables very fine adjustments to be made to the dimensional relationship between a nozzle orifice and a welding contact tip of a wire welding gun.  The welding contact tip is screwed into a tubular adapter that is stationarily joined to the welding gun.  The adapter has a stop that extends radially therefrom.  The nozzle is part of an extension assembly that is rotatable on the adapter.  The extension assembly includes an insert with an end that is at an oblique angle to the adapter longitudinal axis. By rotating the extension assembly on the adapter while holding the insert angled end against the stop, the extension assembly and thus the nozzle orifice reciprocate relative to the welding contact tip.  The extension assembly is rotated on the adapter until the nozzle orifice is at a desired dimensional relationship with the welding contact tip.  The extension assembly is comprised of a tubular sleeve, insulator, and insert.  The three components are assembled together into a unitary extension assembly by radially swaging the sleeve to the insulator and the insulator to the insert.

Title: Impact-absorbing barriers for highways
Inventor: BERNAQUEZ NORMAND
IPC: E01F15/14
Filed: 1995-03-20
Abstract: The road-guard construction comprises a first wall of superimposed whole tires disposed horizontally in vertical rows and horizontal columns. A second wall of superimposed half tires - which are cut circumferentially along their tread path, is also disposed in vertical rows and horizontal columns. Each half-tire defines a toroidal chamber, facing upwardly. Tie-bands interconnect the whole tires to the half-tires, whereby a single integral wall unit is achieved. Sand is poured into the toroidal chambers of the half-tires, whereby the first and second walls become firmly anchored to the ground. The road-guard will therefore remain substantially immobile over ground even after repeated vehicle impacts.
