Patent CA-1280317-C (CA)
Title: Structure having a movable panel
Inventor: WEBSTER JAMES A
IPC: E05D15/10
Filed: 1986-04-22
Granted: 1991-02-19
Abstract: ABSTRACT     A structure having a movable panel     has a support frame     having side portions      slidably mounted on supports to allow sliding movement of the frame between a retracted and an extended position. The movable panel     is mounted on the frame     via interengaging track means preferably comprising a track of part-circular cross-section  and arcuate means . The arcuate means     allow a first tilting of the movable panel     from a flush-fitting plane to an inclined plane on sliding movement of the frame     from the retracted to the extended position, and also allow a subsequent second tilting of the movable panel     from the inclined plane to a non-flush plane substantially parallel to the flush-fitting plane. The interengaging means       allow lateral sliding of the movable panel    in the non-flush plane. Thus one end of the movable panel     may be transferred between planes before the opposite end, enabling one person to handle large panels with ease. The need for large internal frames is obviated.

Title: Laundry tub pressure switch control means
Inventor: ARMSTRONG GERALD
IPC: G05D9/12
Filed: 1986-10-03
Granted: 1990-10-16
Abstract: ABSTRACT     In applications where the liquid level in a laundry tub, sump, or other waste vessel is automatically controlled on an infrequent basis, a pressure control switch assembly in direct contact with the waste liquid, is also connected to the discharge line of a pump such that when the liquid level exerts sufficient pressure to cause the pressure control switch to depress and engage the pump, a portion of the discharge water of the pump is recirculated to the pressure control switch maintaining the pressure thereon until all of the liquid in the vessel is exhausted.  This alleviates any problems of fluctuating pressure due to the dynamic flow characteristic of the waste water being discharged.

Title: Screening techniques by identification of constant grey components
Inventor: ROETLING PAUL G
IPC: H04N1/405
Filed: 1987-08-24
Granted: 1992-12-15
Abstract: ABSTRACT OF THE DISCLOSURE           Identification of constant grey components in electronic screening by first determining from the continuous-tone input, the maximum value of grey, the minimum value of grey and the average value.          The average value is used to determine how many white bits are to be turned on in the halftone dot generated. Since "Moire" problems only occur only from the fluctuating part of the input, the three grey ranges corresponding to the minimum, the maximum and the fluctuating portions of the grey found in the area are then treated separately. The minimum and maximum grey levels identify constant levels within the grey area. That is, every point is at least as light as the minimum and every point is no lighter than the maximum. A template black dot corresponding to the amount of black in the maximum light grey area is generated and correspondingly a template white dot corresponding in size to that for the minimum grey level is generated, and compared to those actual dots created by ordinary halftoning. The ordinary halftone process produces black in at least the area of the template black dot and white in at least the area of the template white dot. The fluctuating grey levels between these two control the remaining dot area as to which is black and which is white.

Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE     A sheet feeding apparatus with a sheet support tray, a rear vacuum plenum chamber adapted to acquire the rear portion of a sheet, a front vacuum plenum chamber positioned over the front of the sheet and adapted to acquire the front portion of a sheet, a sheet transport associated with the front vacuum plenum to transport a sheet acquired in a forward direction and an air knife positioned at the rear of the stack of sheets to inject air between the trailing edge of the top sheet in a stack and the remainder of the stack. The trail edge of a sheet in a stack is separated by the air knife, acquired by the rear vacuum plenum then acquired by the front vacuum plenum and transported in a forward direction. As the trailing edge clears the rear vacuum, the rear vacuum, which together with the air knife is continuously actuated, acquires the next sheet in the stack. In this way, the speed of the sheet feeder can be very high since sheets are separated and acquired by the feeder simultaneously with transporting them off the stack. Preferably, the air knife includes preacquisition fluffer jets to initially loosen the top few sheets in the stack and lateral converging air streams to facilitate separation of the topmost sheet in the stack. The front vacuum plenum includes sheet acquisition tunnels over virtually its entire sheet contact surface in order to accommodate a wide variety of sheet sizes.
