Abstract: ABSTRACT OF THE DISCLOSURE         SUBSURFACE PUMPING INSTALLATION FOR HANDLING VISCOUS OR SAND-LADEN FLUIDS           A subsurface pumping installation in which solvent or diluent is introduced to the well from the surface and blends with the well fluid to enable it to be pumped more readily.  The diluent is introduced through a power tubing which may be either concentric with the casing or concentric with a production tubing within the casing.  A mixture of well fluid and diluent is conducted to the surface through an annulus which surrounds the power tubing.  The diluent is injected into the well fluid in a blending chamber inside the pump, where it blends effectively without loss into the formation around the pump.

Abstract: 1 ABSTRACT DISPOSABLE DENTAL CAPSULE The reactive precursors of a dental amalgam are stored in separate chambers of a disposable dental capsule which allows the precursors to be mixed when desired with no special manipulation of the capsule by the user. The capsule comprises a closed cylindrical container divided into two noncommunicating, internal chambers by a movable, flexible disk. The dental capsule may contain mercury in one chamber and silver powder and a mixing pestle in the other chamber. When placed in a dental amalgamator, the mixing pestle drives the flexible disk to the end of the vessel of the container forcing the mercury to flow around the edges of the disk and to mix with the silver powder, thereby forming the dental amalgam.

Abstract: ABSTRACT            A street clearing device has a share member that is adapted to be moved by a vehicle over a surface to be cleared.  A rotary member is supported below the share member.  A hard scraping blade and an elastic scraping blade are mounted at an angle with respect to each other at the rotary member so that the hard or the elastic scraping blade selectively adopts an operative position with respect to the surface to be cleared that is dependent on the angle of rotation position of the rotary member.  The other scraping blade is oriented substantially upwardly or rearwardly.  A toggle lever with two legs supports the rotary member against rotation.  A mounting device holds the toggle lever at least approximately straight in the operative position of the hard scraping blade and bent in the operative position of the elastic scraping blade.  The street clearing device is design-ed such that the evasion behaviour of the hard scraping blade on the one hand and the design, dimension and operation of the mounting device, on the other hand, are largely independent of each other.  This is achieved by both legs of the toggle lever, in their at least approximately straight position, being adapted to yield in their common longitudinal direction against the resistance of a biased spring, and the mounting device being arranged so that it remains substantially unload-ed and unchanged in length when the hard scraping blade makes evading movements.

Title: Chemically excitable fluorescer-labeled specific binding assay
Inventor: BOGUSLASKI ROBERT C
IPC: G01N33/536
Filed: 1979-12-10
Granted: 1982-10-12
Abstract: ABSTRACT OF THE DISCLOSURE A specific binding assay method and reagent means for determining a ligand, such as an antigen or antibody, in, or the ligand binding capacity of, a liquid medium which employs a fluorescent substance, i.e. a fluorescer, as a label. The improvement comprises measuring the fluorescer-label by chemically exciting the label and measuring the resulting light emitted thereby. Chemical excitation of the label is preferably accomplished by exposure to a substance, such as a high energy intermediate produced by the reaction between hydrogen peroxide and highly reactive materials such as oxalyl chloride, oxamides and bis-oxalate esters. The assay may follow conventional homogeneous and heterogeneous formats. The improved assay is more convenient than conven-tional fluorescent binding assays by obviating the need for photogenic excitation of the fluorescent label.

Abstract: ABSTRACT         The operational range of an adjustable focus lens is subdivided into a plurality of focus zones, of finite size, by a lens control system that produces a plurality of discrete signals representative of said focus zones, said control system utilizing bidirectional drive means to position the movable element of said lens to one of said focus zones from any position within said operational range in order to focus an image of a remote object at an image plane.  The present invention optimally increases the focusing of said control system while equalizing and minimizing the focusing error introduced into said control system resulting from the use of such focus zones with bidirectional drive means, by anticipating the arrival of said movable lens element at the desired focus zone and then interrupting the driving force provided by said drive means for a limited period of time prior to the time that said lens element arrives at said desired focus zone.

Abstract: ABSTRACT:        "Device for determining local absorption differences in an object".     The invention relates to a device for determining local absorption differences in a planar object section, comprising an X-ray source and an X-ray detector which is directed towards the X-ray source and which comprises a number of plate-shaped collimating elements which are directed towards the X-ray source. On the respective lines of projection of these collimating elements towards the source, there are arranged radiation absorbing elements whose dimensions, measured in the direction of the X-ray source, are smaller than those of the collimating elements and whose dimensions measured in a direction at right angles and in the sectional plane are larger than -those of the collimating elements. Apparent variations in. the sensitivity of the X-ray detector due to a lateral shift of the X-ray focus in the X-ray source, are thus sub-stantially mitigated.

Abstract: Case 2705 IMPROVED LOAD SHARING CONTROL SYSTEM     ABSTRACT OF THE DISCLOSURE           A load sharing system for sharing load between two synchronous motors coupled to drive a common mechanical load which has individually operated clutches each coupling its respective motor to the common load. The clutches can be released or pulsed for short intervals to bring the sharing of load to within, for example, ?5%. At least one of the synchronous motors, and preferably two, has an auxiliary field winding on the rotor with the same number of poles as the direct axis main field winding but providing when energized with direct current a magnetic polar field whose axes are displaced singularly from the axis of the direct axis main polar field.  Thus, by controlling the current the resultant of the direct axis main field and the auxiliary field can be shifted. The auxiliary field winding is of a small size sufficient to provide load sharing control within, for example, ?15%. Thus, the combination of clutch load sharing and auxiliary winding load sharing retains all the significant advantages of each of the separate systems and provide continuous control at a reduction in cost and space requirements.
