IPC: G03G15/00
Filed: 1986-10-22
Granted: 1990-12-18
Abstract: ABSTRACT           A  device  for  positioning an original in sheet form  on  the  exposure  platen  of  a  copying   machine, comprising  abutment  strips which extend parallel to each other at opposite  sides  of  the  platen  and  which  are displaceable  to and from each other for adjusting them to the width of an original fed between the strips on to  the exposure  platen.  In front of each strip and displaceable therewith is at least one pair of  rollers  disposed  with their axis parallel to the strips.  A first roller of each pair  being  closer  to  the  exposure  platen   and   the associated  strip  than  the other roller of that pair.  A flexible belt for pressing an original on to the platen is trained  between  the platen and the said first rollers of each pair and about said first  rollers  and  in  opposite direction over said other rollers and then over the strips towards the frame of the device.     For positioning an original fed on to the platen flat against the platen, the first rollers are moveable in a direction perpendicular to the platen in order to  press the  flexible  belt  against  the original to close to the abutment  strips,  irrespective  of  the  width   of   the original.

Abstract: ABSTRACT     A method and an apparatus for sealing a cable junction are provided.  To seal a cable junction, an insert is placed between two branch cables of the junction, which is then enclosed by a heat shrinkable envelope.  The insert has at least one insert part having a block of heat fusible material attached by one or more flanges of heat conductive material to the branch cables.          The block lies between the branch cables at least partially inside the envelope.  Then, when the envelope is heated to cause it to shrink, the block fuses, thus forming a seal.  For most sizes of branch cables, two insert parts may be used, but three or more may be used for large branch cables.  The flange preferably has a tongue extending into the block to assist heat conduction.

Title: Anti-retroviral agents and delivery system for the same
Inventor: WEINSTEIN JOHN N
IPC: A61K9/50
Filed: 1988-04-08
Granted: 1993-04-06
Abstract: ABSTRACT OF THE DISCLOSURE         The present  invention provides  a method  for preventing or treating disease caused by retroviruses, particularly human immunodeficiency virus.  Liposomes are prepared containing phosphorylated derivatives of nucle-osides which act as chain-terminators of viral DNA.  The phosphorylated nucleosides per se, without encapsulation in liposomes, do not readily enter cells.  However, they are found to be effective if encapsulated in liposomes because they remain in liposomes longer,  they do not escape easily from cells, and they constitute the active form  for  incorporation  in  viral  DNA  chains.    When administered to a host, the liposomes are taken up by endocytic  and  phagocytic  cells,  which  are  important reservoirs of HIV infection.   If coated with an appro-priate ligand, such as an immunoglobulin molecule, lipo-somes containing the phosphorylated nucleosides can be directed  to  phagocytic  cells,  CD4-positive  cells,  or infected host cells.

Title: Digital echo canceller
Inventor: VAN GERWEN PETRUS J

Granted: 1993-05-18
Abstract: ABSTRACT Digital echo canceller A digital echo canceller [1] with a good protection against double-talk comprises a first filter [9] for the echo cancellation proper, a second adaptive filter [11] for making continuously adapted filter coefficients available to the first filter [9] and gate means [15] which will only apply the adapted filter coefficients to the first filter [9] if certain conditions are satisfied. In the echo canceller [1] a specific filter combination is used, in which the first filter [9] is a time-domain programmable filter (TDPF) and the second filter [11] is a frequency-domain block-adaptive (FDAF), and further means [20,20(1)] are provided that are arranged in cascade with the gate means [15] for transforming the frequency-domain filter coefficients [W(p;m)] of the FDAF [11] into time-domain filter coefficients [W(i;m)] for the TDPF [9]. These measures result in the advantages of a negligible delay in the echo cancellation by the TDPF [9], and of the possibility to improve in a simple manner the convergence behaviour of the FDAF [11] and considerably reduce its computational complexity.

Title: Flowmeter for a moving packed bed
Inventor: BAILEY RALPH T
IPC: G01F1/34
Filed: 1988-11-23
Granted: 1993-05-25
Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus and method for measuring the flow of a packed bed of particles moving in a primary stream comprises positioning a feedpipe having an open end facing downstream in the primary stream and feeding a secondary stream of particles through the feedpipe to satisfy a void that would otherwise be formed downstream of the feedpipe due to the passage of the primary stream of particles.  The flow of the primary stream is proportional to the flow of the secondary stream.  The flow of the secondary stream can be measured either by measuring the amount of particles being metered into the feedpipe or by connecting a hopper to the feedpipe and measuring the rate at which a level of particles in the hopper falls.

Abstract: ABSTRACT          Method of and apparatus for measuring the effective viscosity and the elastic properties of coatings.  In previously known "rolling sphere" methods for measuring the effective viscosity and elastic properties of coatings, the disadvantage exists that the inclination of the coated plate causes the forma-tion of runs and also the settling of the relatively heavy solvent vapors.  In order to exclude this disadvantage of the known methods, the coated substrate is aligned horizontally, and after being displaced from the position of rest of a magnetic field, a magnetizable sphere is excited to rolling motions in conjunction with the movement of the horizontally arranged substrate under the influence of the field gradient of a permanent magnet or electromagnet arranged underneath the substrate, these motions serving as the basis of measurement.

Abstract: Hypochlorite digestion of bacterial biomass to re-cover intracellular poly-.beta.-hydroxyalkanoic acid  (PHA)  has not been used on a large scale since it has been widely reported to severely degrade the polymer.   The process of the invention proposes to optimize the initial biomass concentration, the digestion time and pH of the hypochlorite solution to minimize degradation.  Consequently, PHA of up to 95% purity with an average molecular weight of  600,000 can be recovered from biomass initially containing PHA having a molecular weight of 1,200,000. By incorporating a pretreatment step with an anionic surfactant solution,  PHA of 99% purity with a molecular weight of 1.20 x 106 was obtained from biomass containing 57% PHA by weight with an initial molecular weight of 1.25 x 106.
