Title: Charged-coupled device with diode cut-off input
Inventor: PELGROM MARCELLINUS J M
IPC: G11C19/28
Filed: 1987-04-02
Granted: 1991-10-29
Abstract: ABSTRACT: Semiconductor device.         The invention relates to a CCD having a so-called diode cut-off input, a reference voltage being applied to the input diode and the input signal being supplied to an input gate located in front of the first clock electrode. Especially if the electrodes are composed of a transfer part and a storage part with an incorporated potential dif-ference, it is possible that incomplete charge transport occurs from the input to the first clock electrode. In or-der to avoid this incomplete charge transport and/or to be able to enlarge the dynamic range of the input signal, a larger clock voltage, for example 10 V, is applied to the first clock electrode than to the following clock elec-trodes, for example 5 V. In a preferred embodiment, the 5 V clock voltage can be supplied for this purpose via a boots-trap circuit of the first clock electrode. Fig. 3,4.

Title: Forming board for papermaking machine
Inventor: MALASHENKO ALEXANDER
IPC: D21F1/10
Filed: 1987-11-06
Granted: 1991-10-01
Abstract: FORMING BOARD FOR PAPERMAKING MACHINE               ABSTRACT OF THE DISCLOSURE         A papermaking machine having a forming wire, a headbox and a forming board is disclosed.  The headbox includes a lower slice having an apron positioned substantially in alignment with and closely adjacent the forming board such that as the forming wire travels over the the forming board the jet of paper stock leaving the headbox is laid onto the wire at the board at substantially zero angle of impingement.  The forming board further includes a lead-in blade over which the wire travels.  The blade acts to deflect fluid, normally pumped by the wire along its path of travel, away from the underside to the jet of paper stock prior to this jet reaching the forming board.  Advantage is found with the disclosed papermaking machine in that it substantially eliminates pumping of fluid to the underside of the stock, has zero angle of impingement of the stock onto the wire and prevents drainage at the point of impingement which reduces the loss of fine fibres through the wire and minimizes the disturbance of the paper stock resulting in better paper formation and increased operating speeds.

Abstract: Improved Process For Synthesizing Ammonia Abstract Means are disclosed for lowering the temperature of the gaseous effluent from the first catalyst bed in a continuous ammonia synthesis process in which a syngas mixture  containing  nitrogen  and  hydrogen  is  passed sequentially over two or more catalyst beds containing ammonia synthesis catalyst.   This cooling, effected to promote  the  exothermic  ammonia-forming  reaction,  is accomplished by subjecting the gaseous effluent from the first catalyst bed to heat exchange in a high temperature heat  sink,  preferably  after  having  undergone  heat exchange  with  the  synthesis  gas  feed  to  the  first catalyst bed, to control the temperature of the effluent entering the second catalyst bed to a desired level.

Abstract: 6-(substituted amino)purine cytokinins, including kinetin, have been discovered to ameliorate the adverse effects of aging on mammalian cells, by slowing or reversing the morphological changes that normally accompany aging of such cells, without significantly increasing the growth rate or total proliferative capacity of such cells.  Thus, methods are provided for countering the adverse effects of aging on cells in culture and in vivo which comprise administering to said cells an adverse-age-effect-ameliorative amount of kinetin or another 6-(substituted amino)purine cytokinin.  Compositions for carrying out the methods are also provided.  Among the preferred applications of the invention are the preservation of the health of mammalian cells in culture and, by application to human skin of kinetin-containing lotions, ointments or creams, the health and youthful appearance of the skin.

Granted: 1991-11-19
Abstract: Abstract of the Disclosure A transmitter for an alignment system in which a field of electromagnetic radiation is propagated in a non-planar reference cone is disclosed.  The transmitter includes a chassis with a source fixed to the chassis for providing a beam of electromagnetic radiation and an optical deflector which converges toward the source reflects the beam into an omni-directional cone of radiation.  A flexible support having an omni-directional stiffness supports the optical deflector in the beam to reflect the reference field in a level orientation when the chassis is level.  An angular error in the orientation of the chassis from level results in the optical deflector deviating from the aligned position to maintain the reference field in the level orientation.          Damping of the deflector is also provided for and sensors detect when the angular error of the chassis has exceeded an allowable amount.

Abstract: ABSTRACT OF THE DISCLOSURE    FRAMEWORK FOR SUPPORTING SURGICAL INSTRUMENTS                 AT A SURGICAL WOUND     Framework  for  supporting  surgical  instruments such as retractors at a surgical wound includes a pair of  rigid  frames  that  together  form  a  rectangular retractor ring from which surgical instruments such as retractors can be suspended above an operating table, thus eliminating the need for surgical assistants to hold instruments by hand.   Each of the rigid frames has  a  cross  arm  that  is  releasably  and  rotatably attached  to  a  crosspiece  that  extends  across  the operating table.   This rotatable attachment enables either of the frames to be pivotably retracted from time to time to afford better access to the wound.          While one of the rigid frames is so retracted,  the other can continue to support surgical instruments. the framework is especially useful in back surgery in combination with a  kneeling attachment  including  a platform on which a patient kneels.

Title: Method and apparatus for bending tubing
Inventor: STANGE RONALD R
IPC: B21D7/024
Filed: 1988-07-26
Granted: 1991-10-29
Abstract: Abstract of the Disclosure Tube bending apparatus in which a tube is clamped between a U-shaped bend die and a cooperating pressure die, the pressure die being advanced in a linear direction as the bend die is rotated, a tube groove in each of the dies embracing diametrically opposite sides of the tube.  The tube groove on the bend die is of generally U-shaped con-figuration having a semi-circular bend section and opposite sides extending in tangential directions to define tangen-tial grooves along opposite sides of the bend die, the cross-sectional radii of curvature of the tube groove along the bend section and tangential sections are closely controlled to impart some temporary distortion to the tube which will resist wrinkling or collapse.  Similarly, the tube groove on the pressure die has cross-sectional radii of curvature corresponding to those of the bend section of the bend die in order to cooperate with the bend die.  In carrying out the method of the present invention, the tube to be bent is clamped between the pressure die and bend die so that it is forced to assume the configuration of the tube grooves on the pressure die and the bend section of the bend die as the bend die is rotated and the pressure die is advanced while maintaining a constant pressure on the tube.  Preferably, the pressure die is advanced at variable pressure rates as the tube is bent around the bend section of the bend die so that the pressure die will impart a force tending to minimize the reduction of the outer wall of the tube as the inner wall of the tube is compressed.
