Title: Variable high/low vacuum/blower device
Inventor: STEINER ROBERT E
IPC: A47L9/00
Filed: 1993-01-19
Granted: 1996-01-09
Abstract: A variable high/low vacuum/blower device is disclosed as including an interchangeable vacuum or blower device with high pressure/low air flow or low pressure/high air flow operation.          The device includes a housing having air flow channels.  Air inlet and air outlet ports or openings extend through the housing and are connected to the air flow channels.  Motor driven blower wheels create air flow through the air flow channels.  A first valve, operable between first and second position, can selectively change the air flow in the air flow channels from high pressure/low air flow to low pressure/high air flow, while a second valve, also operable between first and second positions, can selectively change the air flow through the air inlet and air outlet ports or openings, enabling the device to operate either as a vacuum or blower device.  The first valve is adjustable to variable positions from high pressure/low air flow through zero to low pressure/high air flow.  The second valve is also adjustable to variable positions from maximum vacuum through zero to maximum blowing.

Abstract: The present invention relates to a method and apparatus of accessing a customer premises device from a data accessing device via a telecommunications switching system.  The telecommunications switching system is comprised of a voice band signal switching network for switchably interconnecting multiplicities of inlets and multiplicities of outlets.  The inlets are for connection to interoffice telecommunications trunks.  The outlets are for connection to analog customer lines.  The method is comprised ofdetermining that a class of service for an inlet connected to the data accessing device is a class of service requiring establishment of a suppressed ringing connection; establishing a suppressed ringing connection from the inlet to an outlet of the voice band switching network for connecting the data accessing device to an analog customer line connected to station equipment of a customer and transmitting signals over the suppressed ringing connection for accessing the customer premises device over the analog line from the data accessing device.  In the method, the establishing step comprises determining whether the station equipment is connected via a subscriber loop carrier, and, if so, sending a brief spurt of ringing signal over the connection for enabling the subscriber loop carrier to establish a connection to the station equipment without transmitting a substantial ringing signal to the station equipment.

Title: Ophthalmic lens inspection method and apparatus
Inventor: EBEL JAMES A
IPC: G02C7/04
Filed: 1993-12-17
Granted: 2005-09-06
Abstract: Disclosed is an ophthalmic lens inspection method and apparatus comprising a camera to capture an image of an ophthalmic lens which has been illuminated by a light source. location and intensity at each camera pixel is converted to an electrical quantity which is then transferred and stored in a memory. A computer containing instructions for comparing the intensity and location values of the pixels starts near the center of the receptor field and continues toward the edge of the field until an intensity deviation is encountered. By evaluating the pixels containing intensity variation, an outline of the lens edge is attained. An annulus is generated enclosing the actual lens edge. All the pixels are changed from an absolute intensity value to a gradient value, represented by two transition edges. Feature extraction is performed to locate defective pixels and place them into groups. Once the groups have been determined each is given a score based on the number, type and severity of the defective pixels placed into that group. From that, a weighted score can be given to the entire lens and the lens either passes or fails.

Abstract: A method of smelting aluminum from aluminum ore wherein the powdered ore is mixed with a flux containing substantial amounts of borax, sodium bicarbonate and a copper compound, preferably copper sulphate.  The mixture is placed in a suitable vessel, preferably with a rounded bottom, that can withstand high temperatures and that has an outlet hole in the bottom.  The mixture of powdered ore and flux is heated to a temperature sufficient to melt the mixture and thereby produce a molten material containing aluminum.   The molten material is allowed to flow out of the outlet hole and to cool outside by means of air cooling which results in the aluminum separating out.   Preferably,  the flux comprises about one third borax, one third sodium bicarbonate and about one third copper sulphate.  A suitable ore for this method is nepheline syenite.

Abstract: The present invention is an ink jet printer utilized to enlarge color images. Signals from a scanned image (50) are convened by a color correction computer (51) into control signals (54) representing the density of the individual pixels of that scanned image. The color density signals are used to control the application of ink from ink jet spray nozzles (23A-U) 25A-D) located on a pair of printheads (23, 25). Thus, the ink jet printer of the present invention reproduces the image on both sides of a translucent substrate (13) to enhance the quality of the viewed image. The present invention is further provided with dual air sources to apply the ink. A first air source (34) is pulse width modulated to control the amount of ink sprayed onto the substrate. A second air pressure source (33) is continuously applied to the ink jet spray nozzles to remove the excess ink that accumulates about the nozzles during print operations. The present invention, additionally, is provided with heaters (28) and a wiper arm (38) and sponge (39) which operate together to enhance the adherence of the ink onto the substrate.
