Abstract: Abstract Scanning Optical Card Reader An optical data card random access information system featuring a data card with data tracks transverse to the lengthwise direction of motion of the card in a transport. An electromechanical actuator, having an arm parallel to the tracks, supports a light source for illuminating a track as well as a charge coupled device linear array detector for reading data. Light is directed onto a desired track to be read and preferably the entire track is imaged onto elements of the detector array so that an entire track may be read simultaneously. The card is supported by a carriage which advances the card in the card's lengthwise direction under control of a motor. The lengthwise motion of the card places any desired track under the actuator arm, while crosswise motion of the arm is able to place the track within the field of view of the detector.

Abstract: RECOVERY OF STORED DATA FROM  MUTILATED TAPE DATA BLOCKS           Abstract Disclosed is a tape controller that recovers data from a block of data stored on magnetic tape that has been affected in part by uncorrectable errors such as tape blemishes.  Upon receiving a request for the block of data, the controller causes a tape drive to read the block from the tape.  The controller stores the read data in a buffer memory that is at least the size of the data block.          When the tape drive encounters the affected data while reading the block of data, the controller clears the buffer memory and causes the drive to read the block in reverse.  The controller again stores the read data in the buffer memory, in the order in which they are read.  When the drive again encounters the affected data, the controller reverses the contents of the buffer memory and then causes the drive to read the block in forward.  The controller once more stores the read data in the buffer memory, thereby concatenating the two data portions.  When the drive again encounters the affected data, the controller provides the contents of the buffer memory to a requestor in response to a request for the block of data.

Abstract: ABSTRACT            The invention relates to an electrically controlled valve apparatus  provided  with  an  inlet  conduit  (2)  for  the pressurized fluid, an outlet conduit (12) for the tank (T) in order to discharge the fluid from the valve apparatus and with  an outlet  conduit  (19)  for  an  actuator  proper, such  as  a cylinder  (S).  The  valve  apparatus comprises  a chamber (5) whereto the inlet conduit (2) is connected and which is provided with two openings (10, 11) provided with operating  spindles  (6,  7).  Through  these  openings  the pressurized  fluid can  flow from  the chamber  (5)  via the outlet conduits  (12,  19)  onto  the cylinder  and  into  the tank,  or from the cylinder into the tank according to how the  position  of  the  operating  spindles  is adjusted  with respect  to  the  said  openings.  The  valve  apparatus also comprises  two  throttle  valves  (42)  for  constructing  the conduits (52, 53; 40, 45) located between the back chambers (31,  24)  of the operating spindles  (6,  7)  and  the  fluid tank (T). The operation of the throttle valves is adjusted by means of one or several  electric  actuators  (55).  The valve apparatus also comprises at least one sensor (58) for measuring  the  motional  velocity  of  the  lift  cage  or  a corresponding quality,  and a control unit  (57), which is among  other  things  employed  for  adjusting  the  throttle valves,  by  aid  of  their  actuators,  on  the  basis  of  the information received from the sensors so that the position of the operating spindles,  and the hydraulic flows in the openings regulated by the said operating spindles, are such that the lift cage (HS), the hoist platform or equivalent behaves in a predetermined way.

Abstract: LINE ILLUMINATION SYSTEM     Abstract of the Disclosure An illumination system for illuminating a line on a document which illumination, when reflected and focused via a lens on a sensor (or image plane), has substantially uniform light intensity along the length of the line.  The illumination system includes means for compensation for lens cosine to the fourth power fall-off and an illumination cosine fall-off phenomenon, which has classically been treated as proportional to cosine to the fourth power hut in the example of lamps made of coiled tungsten filaments located along the axis of the foci, is more nearly cosine to the 2.8th power.  The compensation apparatus includes a cylindrical ellipse for focusing light from two lamps located on an axis which is one foci of the ellipse and the line on the document is located at the other foci of the ellipse.  Reflected light from the line on the document is then reflected and focus via a lens onto a sensor.  At the sensor, the image is captured for analysis or other uses, e.g., using conventional techniques for character recognition or image processing.  The uniform intensity at the sensor can be facilitated by the use of appropriate dimensional relationships between components of the imaging system.

Abstract: Abstract of the Disclosure A circuit for quantizing television horizontal phase to subcarrier zero crossings has a voltage variable delay circuit to delay the leading edges of incoming horizontal pulses to produce a delayed horizontal pulse output.  The corresponding leading edges of the delayed horizontal pulse output are input to the clock input of a flip-flop to store the level of a square wave input which has a given transition (high to low, for example) for each zero crossing of the subcarrier.  The stored levels are integrated to produce  an error signal which is used to delay the leading edges of the incoming horizontal pulses so that the leading edges of the delayed horizontal pulse output are time quantized within a narrow window at a subcarrier zero crossing.

Abstract: Abstract A tuning system for tuning non-standard frequency RF television signals provided by cable distribution networks and television accessories conducts first and second consecutive searches by changing the local oscillator frequency.  The first search is limited to search frequencies corresponding to predictable non-standard frequencies associated with the major cable distribution networks.  The second search includes more search frequencies and extends over a wider frequency range than the first.  During an auto-programming mode, in which active channels are identified, for memorization in a channel list portion of a memory, only the first search is conducted to minimize the required time.

Abstract: Designed to carry natural or synthetic fibres into the spinning chamber of the open-end spinning units, the air stream is induced by suction to flow into a space between the tubular structure and the wall of the spinning chamber and, because it is blocked in a downwards direction, the air flows up to carry the fibres into a stationary ring, and then flows down through the centre of the tube.
