Title: Cleaning apparatus for a xerographic  reproduction machine
Inventor: BOROSTYAN STEPHEN
IPC: G03G21/00
Filed: 1980-09-24
Granted: 1984-05-29
Abstract: ABSTRACT OF THE DISCLOSURE        An improved cleaning apparatus for cleaning a photoreceptor in a xerographic reproduction machine includes a rotatably mounted circular cleaning brush and a flicker member within a housing. A portion of the flicker member is in contact with the brush to produce a primary flicking of the brush bristles as the brush rotates out of contact with this portion. Formed in this portion of the flicker member is an aperture in the form of a slot to produce a secondary flicking of the brush bristles as the brush rotates over this portion.The flicker member is contoured so that the angle between the flicker member and brush bristles at the point of initial contact is very small, approximately 5°, but gradually increases to a maximum of approximately 45° before the brush rotates out of contact with the flicker member. A vacuum chamber behind the flicker member communicates with a prenip region adjacent the periphery of the brush through a vacuum aperture formed in a portion of the flicker member not in contact with the brush. This causes a major portion of the air drawn from the exterior of the housing to be drawn through the brush into the prenip region and through the slot and vacuum aperture. An air inlet is formed in the housing adjacent to where the brush rotates out of contact with the flicker member to permit air to be drawn through the housing in the general direction of rotation of the brush.

Abstract: CONTROL APPARATUS FOR VIRTUAL ADDRESS TRANSLATION UNIT                     ABSTRACT       Control apparatus is responsive to CPU I/O commands for initiating chained I/O data transfers to cause virtual address translation (VAT) apparatus to translate a first virtual address to be used in the chained data transfer operation and load the translated (resolved) address in an I/O resolved address register reserved (unique) to the commanded I/O device connected to a shared I/O control unit and to repeat such an operation for each I/O device commanded by the CPU to do a data transfer and responsive to a command from the shared control unit indicating that one of the commanded I/O devices is ready for data transfer to become nonresponsive to further CPU I/O commands and cause the VAT to resolve a succession of virtual addresses for the data transfer and to load the resolved addresses into I/O resolved address registers shared for use by all of I/O devices whereby a data transfer operation can commence using the resolved address in the register unique to the I/O device which is first ready for data transfer and thereafter continue with data transfers using resolved addresses from the registers shared by all of the I/O devices but captured for use by the I/O device first ready for data transfer.  Upon the data transfers being completed for that I/O device, the VAT resolves a succession of virtual addresses and loads them into the shared registers for use during data transfers by the next ready I/O device in response to a command from the shared I/O control unit.

Abstract: ABSTRACT   A device for spreading of radar chaff from airplanes is described. The device comprises a magazine for the chaff which by means of a motor-operated displacement member may be displaced towards an ejection opening. The device comprises a cover having attachment means by which the cover may be applied on the airplane in an existent beam position for hanging of weapons or other equipment.  The cover is also provided with attachment means and in connection to said attachment means coupling members and contact members, respectively, are provided, the contact members being connected to some of the coupling members via transfer means.  The device may be used for a mechanical, electrical or a different adaption between the airplane and equipment or weapons which may be carried by the same and may for example have the shape of a missile launch for firing of hunting missiles.  Thereby is obtained the advantage that it is not necessary to use a beam position for carrying a unit for spreading of chaff only.  As a consequence an airplane may carry a number of symmetrically suspended spreading devices according to the invention, and thereby a high chaff spreading capacity and an effective use of the chaff may be obtained without influencing notably the weapon carrying ability, weight or aerodynamic features of the airplane.  If desirable an airplane may always carry one or more spreading devices according to the invention.

Abstract: SEMICONDUCTOR MEMORY PRECHARGE CIRCUIT            ABSTRACT     A semiconductor memory circuit has half digit lines (116, 118) which are connected to a sense amplifier (120). A memory cell (122) produces a voltage offset on a half digit line (116).  The sense amplifier (120) pulls the half digit line (116, 118) with the lower voltage to ground.  Pull up circuits (126, 128) act to pull the half digit line (116, 118) with the higher voltage up to the supply voltage.  After the pull up operation a precharge signal (84) activates a pair of precharge transistors (132, 134) which couple the half digit lines (116, 118) to a common latch node (110).  The voltages on the half digit lines (116, 118) equilibrate by current flow through the latch node (110).

Abstract: ABSTRACT OF THE DISCLOSURE DOCUMENT FEEDER WITH IMPROVED VACUUM SYSTEM    A document feeder defines a sheet path along which a document sheet is fed across a platen of a copier/duplicator, for example, in order to copy the sheet.  An oscillating vacuum tube feeds sheets from a supply into the sheet path.  The feeder includes a platen vacuum transport having vacuum belts that move the sheet across the platen. The vacuum transport has a first vacuum plenum and a second vacuum plenum located along the sheet path. The first vacuum plenum has a relatively high level of vacuum to insure lifting of the sheet onto the vacuum belts.  The sheet is then transported into the area where it comes under the influence of the second vacuum plenum,  The second vacuum plenum has a somewhat lower level of vacuum, but it is sufficient to retain the sheet on the belts as the belts drive the sheet into engagement with a registration member.  One vacuum blower is used to establish a vacuum in the vacuum tube and another such blower establishes vacuum in the two plenums. Two control valves regulate the flow of air to the blowers from the vacuum tube and one of the plenums.  The vacuum system provides good control and usage of applied vacuums with small fluctuations in vacuum levels in the vacuum conduits.

Abstract: ABSTRACT OF THE DISCLOSURE          A method is disclosed for measuring the air to fuel ratio of an air/fuel mixture being supplied to a combustion process.  This method has the following steps.          An oxygen sensor station is established at which the sensor senses the difference in oxygen partial pressure from a first reference side thereof to a second oxygen measurement side thereof.  The oxygen sensor is maintained at a pre-determined temperature and at a pressure below atmospheric pressure.  The oxygen sensor is calibrated so that the measurement thereby of an EMF between the first reference side thereof and the second oxygen measurement side thereof is indicative of the oxygen partial pressure in a gas stream passing by the oxygen measurement side thereof.         A sample gas stream is drawn into said pressure across the second oxygen measurement side of the oxygen sensor.  This pressure is one which allows samples to be drawn at a constant flow rate independent of that pressure.  A fixed amount of oxygen is added to the sample gas stream.  The oxygen in the sample gas stream is reacted with oxidizable species contained in the sample gas stream prior to passing the sample gas stream across the second oxygen measurement side of the oxygen sensor.  The pressure of the gas sample is measured.  The air to fuel ratio of the air/fuel mixture is determined from the measured EMF of the oxygen sensor, the total pressure of the sample gas stream and the known oxygen addition rate.  Suitable oxygen sensors may be formed zirconia or titania.
