Patent CA-2034684-A1 (CA)
Title: Combination seal and vent
Inventor: MYERS DONALD J
IPC: B65D90/00
Filed: 1991-01-22
Abstract: ABSTRACT   The invention relates to a combination seal and vent particularly for sealing an area from accumulation of environmental elements and other foreign matter and being capable of providing pressure or vacuum relief should such occur. The area to be shielded is enclosed completely except for an opening which is defined by spaced-apart overlapping flanges. The combination seal and vent comprises generally a body member which is adapted to be attached to one of the flanges and which has a seal projecting therefrom. When installed, the seal is normally in sealing contact with the adjacent flange, preventing the ingress of environmental elements into the enclosed area. Should a pressure differential occur between the interior and exterior of the enclosed area, the seal flexes to permit air flow therearound. The seal returns to its sealing position when the pressure has been substantially equalized. Alternately, the seal may be air-permeable which will generally allow continuous pressure equalization while preventing the accumulation of foreign matter within the enclosed area.

Title: Job separator control
Inventor: KALISIAK MICHAEL S
IPC: B26D5/26
Filed: 1991-03-05
Abstract: Continuous forms (e.g. computer paper with individual sheets separated by perforations) of one job are automatically folded and separated from the forms of the next job. Detectable marks are printed within a window onto the first form of one job, or the last of another, in a first mode, or the forms are counted in a second mode. The marks within the window are sensed by an LED sensor, which feeds information to a computer (microprocessor) control.      The computer control effects operation of a cutting blade to sever the last form of one job from the first form of the next. The forms are automatically folded in a festooning action by a Bunch folder.      Hall effect sensors are mounted for cooperation with notched discs on he same shaft as beaters of the Bunch folder, and function as end of travel limit switches for the folder swing chute, to provide relevant data to the microprocessor for proper operation of the cutting blade.

Title: Video cassette combined dust door and dust door latch spring
Inventor: LOVECKY CRAIG
IPC: G11B23/087
Filed: 1991-08-30
Abstract: ABSTRACT OF THE DISCLOSURE      A tape cassette dust door and dust door latch are biased, in a first embodiment, via a torsion spring including a coil, a short leg and a long leg, having an offset, extending therefrom.  The short leg and coil fit onto a polar member on the door and the long leg extends therefrom.   The offset is received in a groove in the cover and a free end of the long leg abuts a projection formed on the latch. In an alternate embodiment, the latch includes a flexing member which allows a second lower portion of the latch to flex relative to a first upper portion, and a leaf spring integrally formed at the first upper portion.  The dust door polar member has a cam lobe which cooperates with the leaf spring. In the first embodiment, when the dust door latch is actuated by the tape player/recorder, the dust door is unlatched and rotated to the open position, thereby loading the long leg of the torsion spring. When the pin is released, the free end of the long leg biases the latch back into a latched position and, simultaneously, the coil, short leg and offset cooperate to return the door to the closed position. In the second embodiment, the pin causes the second lower portion of the latch to flex relative to the first upper portion, and the cam lobe loads the leaf spring upon opening of the door. Upon release of the pin,  the second lower portion of the latch returns to its original position under the force of the flexing member and the door returns to its original closed position under the influence of the leaf spring.

Abstract: AC TO DC CONVERTER HAVING AN ENHANCED POWER FACTOR         ABSTRACT OF THE DISCLOSURE    The invention relates to an AC to DC converter having an improved power factor achieved by combining boost converter operation at the beginning and ending of each half wave of the AC input waveform, with passive operation at the middle portion of each half wave.   The timing of the operation is based on comparing the instantaneous voltage with a stored average voltage, which has the effect of making boost converter operation go off at a fixed angle after the beginning of each half wave and go on at a fixed angle before the ending of each half wave, the angles being independent of the average AC voltage.  The converter increases the power factor to a value between 90 and 97% and reduces the current waveform distortion to between 15 and 29%.

Title: Saw blade drive
Inventor: BUYENS MARC O R G
IPC: B28D1/04
Filed: 1992-01-29
Abstract: ABSTRACT   The saw blade drive is intended for driving a circular saw blade forming part of a non-explosive mining machine. The drive has a motor, a gear train driven by the output shaft of the motor and a hollow spindle driven by the gear train. The spindle in use is locked in a rotationally fast manner to a hub carrying the saw blade. Thus the saw blade rotates in unison with the spindle. The drive also includes a bolt of which the shank passes through the hollow of the spindle and a nut having an internally threaded recess engaged with a threaded end of the shank. The nut bears upon the hub and holds the hub in rotationally fast engagement with the spindle. The head of the bolt is remote from the blade and no part of the drive extends beyond that surface of the blade which is remote from the head of the bolt. This configuration obviates fouling of the blade and permits convenient replacement of the blade, with access being required from one side only of the drive.
