Title: Intraoral vacuum retractor foldable in half comprising two u-shaped members
Inventor: MAKANGA JOSEPH
IPC: A61C5/82
Filed: 1996-03-20
Abstract: An oral vacuum retractor designed to be positioned entirely within the oral cavity and including a frame shaped to fit the mouth. The frame includes an outer portion in the form of two U-shaped members joined together at the ends of their arms and having a sufficient degree of elasticity at the point of connection to enable the retractor to be manually inserted into and withdrawn from the mouth. An inner portion in the form of an additional frame essentially parallel to at least one segment of the outer portion is also provided at a sufficient spacing to let through one dental arch. A dental dam in the form of an optionally stretched rubber sheet may be attached to the frame. As the instrument is tubular, fluids (Fig. 9) may be sucked out of the oral cavity more easily through the connector leading to the suction apparatus. The frame with the extraoral dam includes a sufficiently flexible external frame to which the rubber sheet for use as a dam during dental and intraoral treatment (Fig. 12) is adhered or otherwise attached. The frame may have a variety of shapes and the instrument is designed to be used only once (Fig. 12) (1, 2, 3, 4, 5). The double frame enables the dam to be attached without using an adhesive and may be sterilised. (Fig. 12.2).

Title: Rotary sound path selector valve with biased rotor
Inventor: THAYER ORLA E
IPC: G10D9/04
Filed: 1989-11-06
Abstract: ROTARY SOUND PATH SELECTOR VALVE WITH BIASED ROTOR   ABSTRACT OF THE DISCLOSURE        A rotary valve coupled into the principal sound path of a musical wind instrument for selectively inserting and removing one or more acoustic pipe segments from the sound path is disclosed.  The valve includes a tapered housing enclosing a tapered lightweight rotor having at least one acoustic passage therethrough.  The rotor is comprised of first and second axially coupled portions separated by a biasing spring tending to axially urge the portions apart.  Each rotor acoustic passage is coupled inside the rotor to the rotor portions so as to permit the rotor portions to be axially separated from each other a predetermined distance while preserving the airtight seal between the rotor acoustic passage and each rotor portion.  Hence, the rotor is axially self-adjusting in the valve housing, maintaining seal integrity of rotor apertures to housing apertures without periodic maintenance or adjustment.

Title: Method of detecting failure to tighten screws against works and device therefor
IPC: B25B23/02
Filed: 1990-02-15
Abstract: A method of detecting failure to tighten screws against works includes steps of detecting every screw tightening operation against a work after start of a screw tightening step, counting the number of times of the screw tightening operations detected in the previous step, detecting the completion of the screw tightening step, and comparing a counted value at the time of the completion of the screw tightening step with a predetermined value, thereby informing of a result of comparison.  A device for carrying out this method includes a current relay responsive to a large load current during the tightening operation of an electric screwdriver in a screw tightening step,  a presettable counter for counting the number of operations of the current relay for the purpose of counting the number of screw tightening operations, setting knobs operated for setting a desirable number of screws to be tightened, photoelectric switches for detecting completion of the screw tightening step for the work, and an alarming device for comparing a counted value obtained by the presettable counter and the value set by the knobs when a screw tightening work completion signal is generated by any one of the photoelectric switches.  The alarming device includes a buzzer energized when counted value does not reach the preset value set at the presettable counter.
Patent CA-2010404-A1 (CA)
Inventor: CANTWELL ROBERT H
IPC: H04B1/707
Filed: 1990-02-20
Abstract: A spread spectrum signal detector for sampling a modulated carrier employing a zero-crossing detection means having two independent control loops, a first loop for a zero-mean threshold control and a second loop for AGC control. An IF sampler quantizes the received spread spectrum signals at IF and provides high immunity to interference or jamming. The IF signal is sampled at a number of quarter cycle intervals to allow sampling in sequence of the in-phase (I) and quadrature-phase (Q) components. The output of the IF sampler is two bits, a sign bit and a magnitude bit. The zero-mean threshold control loop using only the sign bit of the I and Q samples sets a threshold level (T0) to detect the zero-crossings of a received waveform. Two magnitude threshold levels are set at fixed offsets from the T0 threshold level. A normalized statistical accumulator using the magnitude bits of the I and Q samples determines the AGC control level for a fixed percentage of outside threshold crossings of the most significant magnitude bit. The I and Q samples are aligned in time, and every other pair of I and Q samples are inverted for digital demodulation of the IF samples to baseband. The baseband samples are provided to a signal processor for generating range and range rate information.

Title: Fluid directing method and apparatus for aiding the shaping, polishing and smoothing of a work piece by sanding
Inventor: HICKS THOMAS W
IPC: B05B15/06
Filed: 1990-03-05
Abstract: ABSTRACT    A fluid directing means is described that can be used with a conventional garden hose or connected directly to a water tap for applying a linear array of water across a work piece undergoing repair (consisting essentially of side-by-side streams of water).  It consists of a flexible hose of cylindrical form closed by a far end wall and having a series of openings along a segment of its side wall through which the wetting fluid is dispensed.  Because of the size, shape and orientation of the openings, a linear source array of wetting fluid is formed for dispensing the fluid as  a series of side-by-side streams across the work piece in sufficient volume to facilitate the shaping, smoothing and polishing of the damaged area but not does not commit undue waste of the fluid.  In addition, a series of non -marring suction cups are provided along the hose.  The cups are oriented with respect to the hose so that the working edge of each cup define a  suction plane normal to the axis of symmetry of each opening.  Furthermore, the end of the openings are offset a common distance d from the surface of the work piece  since the offset distance from the center of the misting segment to the suction planes are constant along the hose.  Hence, once the cups are attached to the work piece, the array of openings directs the wetting fluid in a series of streams that impact the surface of the piece at a maximum impact angle (90 degrees) but without undue aeration of the wetting fluid.   Also since the cups are attached by suction alone, they can be easily re-arranged as required.    In one arrangement, with an array length of about four feet, the cups and hose are arranged so that the arrangement can be placed upon a vertical surface of the work piece at a common height above the earth's surface.  In another arrangement, the array is sinusoidally positioned about an axis that can also be of common height above such surface so that there is an increase in the volume of wetting fluid per unit length without need to vary the volume of wetting fluid entering the near end of the hose.
