Title: Coaxial connector center conductor captivation with electrical compensation
Inventor: SLADEK NORBERT J
IPC: H01R24/38
Filed: 1979-05-16
Granted: 1981-11-24
Abstract: ABSTRACT            The present invention relates to an electrical con-nector having inner conductor captivation with electrical compensation.  It is well known that axial and rotational loads on the inner conductor are frequently encountered during normal use of a connector causing potential signal interference or interruption.  Additionally, the problem is aggravated when-ever a substantial tension is placed on the cable being joined by the connector or by thermal shock which can cause relative size changes in the components of the connector.  The present invention overcomes these problems of the prior art by pro-viding an improved connector including an outer conductor, a dielectric member disposed within the outer conductor or shell having an axial opening extending therethrough, an inner con-ductor or contact disposed within the axial opening in the di-electric member in electrical isolation from the outer conduc-tor, and means for captivating the inner conductor against axial and rotational movement within the opening.  The con-nector is characterized by the captivating means providing an electrical impedance  differing from the electrical impedance remote therefrom and further includes means for compensating for the differing electrical impedance  provided by the capti-vating means adjacent thereto.  With these features of con-struction, the connector not only effectively captivates the inner conductor but also effectively compensates for the dif-fering electrical impedance resulting therefrom.

Abstract: VARIABLE FLOW EJECTOR                    ABSTRACT        A variable flow ejector for use in controlling the amount of bypass flow in a fluid delivery system which includes a pump, a metering orifice and a bypass line for circulating a variable amount of flow from the pump outlet to the pump inlet to control the pressure drop across the orifice.  The bypass flow enters the ejector through a variable area nozzle coaxially disposed with respect to a stream from a source of fluid whereby the velocity head of the bypass flow is recovered as pressure head at the pump inlet for increased efficiency.  The bypass flow is controlled by varying the area of the ejector nozzle as a combined function proportional to the pressure drop across the orifice plus the time integral of the error in the pressure drop across the orifice.

Abstract: VENDOR CONTROL CIRCUIT           Abstract of the Disclosure A control circuit for a vendor for vending a plurality of items comprising a microprocessor, an electrically alterable memory, a display circuit and an interrogation circuit.  Values of parameters, typi-cally prices, associated with the items to be vended are stored in the memory.  The interrogation circuit can be activated to retrieve from memory the value of the parameter (e.g., price) associated with any given item.  The parameter value is thereupon displayed by the display circuit.  The display circuit displays the parameter value retrieved from memory independently of whether the microprocessor has another input equal in value to the value of that parameter.  The parameter value stored in the memory for any given item can be altered by the microprocessor.

Abstract: PHN.9253.            ABSTRACT          High-pressure sodium vapour discharge lamps are used which contain an electron-emitting material consist-ing of alkaline earth metal bound to oxygen and tungsten bound to oxygen.  It has been found that such lamps which have a high Hg/Na ratio, use neon/argon as a starter gas or have powers of less than 400 W fail prematurely when the alkaline earth metal and tungsten in the electron-emitting material are present in stoichiometric quantities (total alkaline earth metal oxides: W03 = 3). The free ends of electrodes of lamps according to the invention are wound with tungsten wore. Electron-emitting material consisting of strontium bound to oxygen and tungsten bound to oxygen is disposed in the cavities formed between the tungsten wire turns.  The molar ratio of the strontium bound to oxygen to the tungsten bound to oxygen is between 3 and 50.

Abstract: INTERNAL COUPLING STRUCTURE AND JOINT FOR PIPE OR TUBING   (Abstract of the Disclosure) A coupler structure which facilitates the internal joining of a first length of hollow plastic pipe having internal corrugations defined by a plurality of alternating peaks and valleys to a second length of similar pipe or to some other structure.  The coupler is molded from plastic to have at least one cylindrical end portion dimensioned for longitudinal receipt in the second length of tubing or other structure which is to be coupled to the first length.  This one end portion includes a plurality of integrally molded cleats extending generally radially outward thereof.  The cleats are selectively movable between first locking positions for lockingly engaging the second tubing length valleys and second non-locking positions which permits forced insertion of the coupler one end portion into the second tubing length.  The cleats are hinged to the one end portion generally laterally thereof and are continuously urged toward the first position by the resilient nature of the plastic construction.  A tab or tongue-like structure extends outwardly from each cleat generally longitudinal of the coupler one end and is dimensioned to extend beneath the next adjacent second tubing length peak when the cleat is in locking engagement with a second tubing length valley.  This, in turn, acts to self energize the cleat to enhance its locking capabilities when a pull force is applied to the tubing.  The coupler preferably comprises a separate structure including a pair of generally opposed end portions for joining two similar lengths of plastic pipe.  The coupler also preferably includes flexure means intermediate the end portions to accommodate bending at the tubing joint.

Abstract: 48D-291 Can Abstract A lubricating system which is completely self contained within the vacuum environment of an electric direct drive system for an ultracentrifuge rotor.  The lubricating system also func-tions as a cooling means for an electric motor within the drive system by the use of a unique cooling feed tube in the central portion of the drive system.  An orifice in the top of the cooling feed tube will control the head of the lubricating medium within the system.  Specific design of the fit between the direct drive assembly and the drive housing in conjunction with the head on the lubricating medium will regulate the drip rate of the lubri-cating medium to the bearings.  The use of the unique lubrication and cooling system maintains the close tolerances of the various elements such as the high speed bearings of the drive system because the temperature of the overall drive system is controlled.

Abstract: RCA 73,304 Abstract of the Disclosure A video signal dropout compensator stores information from at least one incoming television line which is represented by a plurality of samples of combined luminance and chrominance signal components.  The samples occur at a rate equal to four times the chrominance subcarrier frequency.
