Title: Interleukin-2 receptor and DNA encoded therefor and their preparation
Inventor: CERRETTI DOUGLAS P
IPC: C07K14/705
Filed: 1985-05-21
Abstract: Interleukin-2 receptor derived from normal and malignant cells has been purified by use of various techniques including affinity chromatography in conjunction with a monoclonal antibody directed to the receptor. The purification process also includes reversed phased high performance liquid chromatography. By these techniques, interleukin-2 receptor has been purified to homogeneity. The high purification of the interleukin-2 receptor has made possible the sequencing of the amino acid residues at the N-terminal of this protein molecule. Double-stranded cDNA is prepared from polyadenylated RNA extracted from cell lines or other sources known to produce IL-2 receptor. The cDNA is inserted within a plasmid vector and then the recombinant plasmid employed to transform an appropriate host. Transformed hosts are identified and grouped into pools. Plasmid DNA prepared from these pools is hybridized with a labeled synthetic oligonucleotide probe corresponding to a portion of the amino acid sequence of the purified IL-2 receptor. The cDNA clone isolated with the probe is characterized by restriction enzyme mapping and sequenced by chain-termination method. The particular DNA clone that actually contains the gene coding for the functional IL-2 receptor is identified by expressing the clones in COS-7 monkey kidney cells and assaying for the expressed IL-2 receptor by its ability to bind IL-2 or a monoclonal antibody directed against the IL-2 receptor.

IPC: G01L23/00
Filed: 1985-10-31
Abstract: A method and apparatus for determining the absolute compression pressure of each cylinder in an internal cbm- bustion engine is disclosed. The technique involves analyzing the changes in engine kinetic energy in order to calculate both the work of compression and expansion of each cylinder in a multi-cylinder engine typically during a decelerating engine cycle. Speed data is obtained and the work associated with the compression and expansion process for each cylinder is calculated and compared to the compression and expansion data of a good engine which is stored in computer memory. If a compression fault is present, it can be detected because that cylinder will display a decrease in both the work of compression and expansion. Once a faulted cylinder has been identified, the maghitude qf the fault'can be calculated and normalized and the compression pressure of each cylinder calculated and displayed.

Abstract: In an assembling machine with a cyclically driven rotary table for accommodating a plurality of workpieces which are directed past substations which are arranged at least partly over the periphery of a fixed machine table and have a drive device for one or more machining devices arranged at the substation, at least one or more substations are provided with an indexing mechanism independent of the cycle of the rotary table. In this way, in particular at converter substations, an acceleration of the assembly can be achieved by overlapping cycles of machine and converter. The substations can be checked out independently of the central machine and can be set up at a greater distance without functional impairment occurring as a result of play in the drive members. A control shaft can be driven by means of a roller chain driven by the central machine. But any other type of drive, e.g. a motor, is also conceivable, so that the indexing mechanism can also be operated as an independent device.

Abstract: Labels 29 are carried on a label strip 31. To detect gaps 33 between the labels a label applicator is equipped with an optical sensing device consisting of a source 47 and a detector 53. A barrier 55 minimizes the passage of light to the detector 53 while a label 29 is passing but when a gap 33 is aligned with 47 and 53 an optical signal is obtained which can be used to control the applicator. 
     If labels 29 are transparent the light is directed at a small angle to the surface such that light entering the label is trapped by total internal reflection and does not reach detector 53. The barrier 55 is resiliently pressed against the label strip but supported by a film of air under pressure.

Abstract: A backing for an absorptive device such as a disposable diaper or a sanitary napkin, said backing comprising a combination of two layers. The first layer which does not contact the wearer's skin is preferably comprised of a liquid-impervious layer of polymeric film or the like. The second layer is also preferably comprised of a polymeric film which has been made pervious to liquid by providing a multiplicity of relatively small proturberances, each ending in an aperture, substantially across its entire surface. The apertured protuberances, which resemble a tiny volcano in cross-section, exhibit a soft, highly consumer preferred tactile impression which is sometimes characterized as «silky». In backsheets of the present invention, the second layer is oriented so that the tiny volcano-like cusps of the second layer constitute the exposed portion of the backsheet. This minimizes the area of contact between the backsheet and the wearer's skin. In a particularly preferred embodiment of the present invention, the second layer is macroscopically expanded to provide a three-dimensional pattern in its surface, thereby increasing the amount of stand-off between the wearer's skin and the liquid impermeable first layer of the composite backsheet. The tiny apertures in the second layer substantially prevent occlusion of the wearer's skin by providing circulation of air between the first liquid impervious layer of the backsheet and the wearer's skin. This effect is enhanced even further when the first layer is macroscopically expanded to enhance the amount of stand-off between the wearer's skin and the liquid impervious first layer. The reduced contact area and the enhanced air circulation between the backsheet and the wearer's skin reduce the tendency toward perspiration and sticking of the backsheet to the wearer's skin.

Abstract: A fluid swivel system of the type suitable for use with a single point mooring system and the like includes mandrel structure (34) that defines a through flow path from a coupling (20) to a port in an outer cylindrical interface surface (50), a port (54) in the outer interface surface. Generally toroidal structure (60) surrounds and is mounted for rotation relative to the mandrel structure, the toroid structure having an inner cylindrical interface surface (62) in juxtaposed relation to the interface surface (50) of the mandrel structure.

Bearing structure (78) between the mandrel and toroid structures is located so that each seal chamber is between the adjacent bearing structure (78) and the through passage (36, 70, 66).

Abstract: It is well known that the base width of a transistor has a direct bearing on transistor speed and the punch-through voltage. A solution to the transistor speed versus break down (punch through) voltage problem is disclosed. Output transistors are serially connected between power supply rails along with associated transistor base driving circuitry. The circuit arrangement ensures that the supply voltage divides between the series connected output transistors and prevents excessive voltage from being applied to each output transistor.
