Abstract: ABSTRACT          An instrument for ophthalmic laser surgery is disclosed, in which lasers are mounted for conjoint movement with a slit lamp on an X-Y table.  The laser beams are directed into the patient's eye by a beam-directing assembly which pivots together with the slit lamp's microscope about a common axis, and which receives the laser beams along that common axis.  The resulting structure greatly improves the ease of use of the laser arrangement and keeps the laser beams in alignment with the microscope at all times.

Abstract: Abstract A spray dryer apparatus for contacting a hot gas stream containing gaseous impurities with an aqueous medium containing an absorbent for the impurities to produce a gas stream of reduced impurity content and dried powder products.  The apparatus includes a chamber formed symmetrically about a vertical axis and an atomizer means located in an upper portion of the chamber for introducing a finely dispersed spray of the aqueous medium.  The apparatus also includes a conduit for delivering the hot gas stream to the chamber and a gas injection means for receiving a major portion of the hot gas stream from the conduit and introducing it circumferentially about the atomizer means.  The gas injection means imparts both axial and angular velocity components to the major portion of the hot gas stream whereby the hot gas stream swirls downwardly through the chamber.    A key feature of the apparatus is the provision of a bypass means for withdrawing a minor portion of the hot gas stream from the conduit and a duct for introducing the withdrawn minor portion of hot gas into the chamber at a tangent to a radius extending from the vertical axis and in a substantially horizontal plane.          An essential feature of the invention is that the minor portion of the hot gas is introduced into the chamber in a direction counter to the direction of swirl of the major portion of the hot gas passing downwardly through the chamber.  Preferably from about 5 to 25 vol. % of the hot gas stream containing gaseous impurities is withdrawn and bypasses the gas injection means, and is introduced into a lower portion of the chamber in a direction counter to the direction of swirl of the major portion of gas which passes downwardly through the chamber.

Abstract: A CONTROL MECHANISM FOR A RING COMMUNICATION SYSTEM      Abstract of the Disclosure The invention provides a ring communication network having an improved error recovery mechanism.  The system uses a token or toggle signal which does not have an inherent control value but one that requires the values of a contiguous pair thereof to control access to the transmission medium of the system.  A station recognizes that the ring is idle is the present value of the toggle signal is the same as the value of the toggle signal in the previous frame.  Conversely, a station recognizes that the ring is busy if the present value of the toggle signal is different from the value of the toggle signal in the previous frame. A station that detects an idle toggle signal and wishes to transmit data on the communication ring changes the value of the toggle signal to that which corresponds to a busy status and transmits its data.                             - i -

Abstract: ABSTRACT     This invention concerns a new monoclonal antibody (mAb) 4C, recognizing a specific antigen, Leu 200, found in human hematopoietic tissues.  The monoclonal antibody precipitates a series of glycoproteins (Leu 200) with a molecular weight range of about 190,000 to 230,000 from both T- and B-cell lines.  The series of glycoproteins resolves into four discrete glycoprotein bands,  the distribution of which varies according to the cell lines.  Bands 3 and 4 predominate in a majority of T-cells whereas band 2 predominates in B cells.  Thus, a Leu 200 antigen subset distribution is possible with mAb 4C.  Bands 1, 2, 3, 4 have apparent molecular weights of 230K, 215K, 205K, and  90K respectively, with differences in their carbohydrate moieties.  mAb 4C is a IgG sub two a,kappa immunoglobulin. 4C has potential use in leukemia, hematopoietic cell differentiation and transplantation diagnoses and therapy.

Abstract: Abstract of the disclosure:     Polypeptides having a carboxamide carboxyl ter-minal end and a methionine residue, which is optionally bonded to a bacterial protein, on the amino end can be prepared by synthesis by genetic engineering methods of the corresponding polypeptide having at the C terminal end a glycine residue, and conversion of the latter enzymatic-ally into the amino group of the desired carboxamide group.  Peptides which have the aminoacid sequence of growth hormone releasing factor, part sequences thereof, or modifications of these peptides, are readily accessible by this means.  The synthesis by genetic engineering methods is advantageously carried out via two gene frag-ments which are synthesized chemically from smaller, single stranded structural units.  The two gene fragments are then linked enzymatically to give the complete gene, which is incorporated into a suitable vector, amplified there, and the peptide is isolated directly or as a fused protein, and is converted enzymatically into the desired amide.

Abstract: Title SCROLL MACHINE WITH DISCHARGE PASSAGE  THROUGH ORBITING SCROLL PLATE AND   ASSOCIATED LUBRICATION SYSTEM             Inventor Robert E. Utter Abstract A scroll compressor enclosed in a hermetic shell, wherein part of the volume enclosed by the shell is at suction pressure and part is at discharge pressure.  The compressor includes both a sta-tionary and a driven scroll plate, with intermeshed involute wrap elements attached to the plates for defining pockets in which fluid is compressed as a drive shaft connected to the driven plate causes it to orbit relative to the stationary scroll plate.  A passage dis-posed within the driven plate and adjacent its axial center conveys compressed fluid through the plate and into a cavity formed in the end of the drive shaft.  Oil entrained in the compressed fluid is thrown radially outward within the cavity, due to centrifugal force, and is thereby separated from the compressed fluid.  The oil then flows through an adjacent bearing, and is thrown radially outward, creating a spray that impinges on a seal which abuts the back sur-face of the driven scroll plate.  A drive shaft bearing also receives lubrication as the oil flows back into the reservoir at the bottom of the shell.
