Abstract: Abstract of the Disclosure - The combination of a conventional antimony - or bismuth-contianing heat stabilizers with certain aromatic esters or aryloxides containing boron, phosphorus, silicon, antimony, tin or zinc interacts syner-gistically to provide an unexpectedly high level of heat stability to halogen-containing polymers such as polyvinyl chloride (PVC).  In addition the aromatic ester or aryloxide inhibits spontaneous degradation of the heat stabilizing component in the presence of heat and/or light.

Abstract: ABSTRACT OF THE DISCLOSURE             The invention relates generally to a method and apparatus useful for cleaning out scouring drainage systems. The invention comprises a method of internally scouring a drainage system comprising the introduction of an abrasive, non-toxic and slowly dissoluable granular compound into a stream of fluid under pressure, directing the fluid into a drain pipe of the system whereupon the compound is caused to contact the interal wall of the pipe and thereby remove accumulated sediment therefrom; subsequently maintaining a flow of fluid under pressure through the system for a period of time sufficient to substantially complete the dissolution of such compound as may remain within the system.  Furthermore, the invention contemplates drain cleaning apparatus comprising fluid conduit means adapted at one of its ends for interconnec-tion with a source of fluid under pressure, the other of its ends being adapted for insertion within a drain opening, the fluid conduit means being further provided, intermediate the length thereof with secondary inlet means; and container means releasably attached to the secondary inlet means such that the contents of the container means may gravitate freely through the inlet means into the fluid conduit.

Title: Compact fluorescent lamp having a partitioned  envelope

Granted: 1983-03-29
Abstract: 18                        47,645 ABSTRACT OF THE DISCLOSURE   The light output of a compact fluorescent lamp is enhanced by providing the envelope with a phosphor-coated partition assembly which has a plurality of panel segments that divide the envelope interior into a series of  interconnected  sectors  and also define a centrally-located core chamber that is closed to the discharge.  The size of the core chamber is correlated with the size of the envelope in such a manner that the discharge is dis-placed from the center of the envelope toward the phos-phor-coated walls thereof, thus reducing losses due to the "trapping" of light deep within the envelope interior and concurrently increasing the relative amount of ultraviolet radiation that reaches and excites the phosphor coating on the envelope wall.  The efficacy of the partitioned fluor-escent lamp is accordingly increased.  The size-correla-tion is rather critical and must be such that the maximum cross-sectional dimension of the core chamber at a given location is  from about 25% to about 85% of the maximum cross-sectional  dimension  of  the  envelope  at  the  same location and optimum results are obtained when this para-meter is around 50%.   The improved fluorescent lamp is thus especially adapted for use as a substitute for incan-descent lamps in various types of lighting fixtures where space is limited and a light source of high brightness is required.

Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure teaches a method for electroslag welding of metals by a large-section electrode.  In accordance with the invention there are provided the steps of placing the workpieces to be welded together onto a metal mould with a gap between the edges to be weld-joined.  An electrode is inserted into the gap until it contacts the bottom of the metal mould.  A slag bath is established.  The metal mould is filled with the metal of the electrode being fused.  The gap between the edges being weld-joined is filled with the metal of the fused-down electrode.  The electrode metal fusion rate is selec-ted in filling the metal mould with the molten metal so that it is less than the electrode metal fusion rate in filling the gap between the edges being weld-joined at constant electrical parameters of the welding with metal. A brittle interlayer is produced in the course of welding after forming a shrinkhead before reinforcing the weld produced in the gap.  A weld is formed with a low elec-trical resistance in the gap and the shrinkhead is removed at the place of the brittle interlayer.

Abstract: TACTILE SENSOR ABSTRACT OF THE DISCLOSURE A tactile area sensor for robots has an array of pneumatic flow passages.  The air flow in each passage is dependent on a localized force exerted by an object pressing against an elastic pad on the face of the sensor.  The air flow impinges on a metallic tab and its angular displacement is sensed by directing a light beam from an optical fiber onto the tab and monitoring the quantity of light reflected to a paired optical fiber.  The array of optical output can be presented to a charge injection device and are dependent on the shape of the object.

Abstract: ABSTRACT OF THE DISCLOSURE        Novel plasmidic expression vehicles and methods of using them in the production of useful polypeptides by recombinant bacteria are described.  The plasmids employ a tryptophan  promoter-operator system from which the attenuator region ordinarily present has been deleted.          Bacteria containing the plasmids can accordingly be repressed by the addition of tryptophan against expression of desired polypeptides coded for by inserted genes while they are grown to levels suitable for industrial-scale production.  Additive tryptophan may then be withdrawn, essentially derepressing the pathway and permitting efficient production of the desired product in high yield.

Abstract: TORQUE-LIMITING CARRIAGE RETURN KNOCK-OFF MECHANISM     Abstract of the Disclosure A carriage return device utilizing a spring clutch and shock unloader spring is disclosed in conjunction with a cord tension sensing mechanism for detecting the cord tension increases when the paper carriage of a typewriter ceases to move and the carriage return drive mechanism continues to operate.  It is desirable to disengage the drive mechanism at that point rather than to cause frictional wear or overloading of the motor pending a predetermined amount of driving time prior to disengagement.          Upon the cord tension reaching a preset value, the clutch pawl will disengage the drive clutch and prevent further wear of the clutching arrangement.  To prevent premature disengagement of the clutch, a shock unloading pretensioned spring is incorporated in the drive unit to absorb the initial shocks of clutch engagement and the forces experienced during acceleration of the paper carriage.

Abstract: ABSTRACT   In a method of heat extraction from an aqucous carrier medium through its expansion, the expansion is untertaken step by step in a number of expansion stages arranged consecutively as regards the flow of the medium. The vapour produced in each expansion stage is removed from the stage, and the individual vapours are subjected, respectively, parallel to eachother, to a thermal utilization or revalorization.            According to one embodiment, the carrier medium is boiler feed water, which is circulated via a heat absorption zone and through the expansion stages. The vapour produced undergoes thermo-compression and is fed to a common steam bar. The heat absorption zone, heat exchangers are heated by a source of waste energy. A produce of this method is a pure water vapour.

Abstract: ABSTRACT OF THE DISCLOSURE     Drill pipe for an oil and gas well drill string has a better bench mark system for determining when the tool joints of the drill pipe are no longer satisfactory for sealing.  The bench mark is an edge formed in the tool joint in the space between the threads and the make-up shoulder of the tool joint.  The edge extends around the circumference of the tool joint for serving as a reference line to measure the distance from the reference line to the make-up shoulder.  On the pin type tool joint, the bench mark edge is formed by forming a cylindrical sur-face in the tapered surface normally located between the threads and make-up shoulder.  In the box type tool joint, the bench mark edge is formed by forming a cylindrical surface in the normal tapered surface to create a bench mark shoulder inward from the make-up shoulder.
