Abstract: Abstract of the Disclosure Implantable variable flow infusion apparatus comprises a collapsible infusate chamber having an outlet conduit leading to the infusion site by way of series-connected fixed and variable fluid flow restrictors.  The infusate in the chamber is maintained under substantially constant pressure by a nonelectric energy storage cell to establish flow from the chamber to the site.  The variable restrictor is controlled by commands from a preprogrammed microprocessor and programmable memory powered by a small long-lived battery.  The processor sets the variable restrictor to the proper setting to establish the correct infusate flow for the particular time of day.  A pressure transducer connected across the fixed restrictor senses the pressure differential across the fixed restrictor which differential indicates actual infusate flow from the chamber.  The processor samples the output from the transducer at infrequent  sampling intervals and issues command signals to control the variable restrictor whenever the actual infusate flow rate differs from the preprogrammed rate so that the apparatus consumes a minimal amount of battery energy and can thus remain implanted in the body for a prolonged period.  The processor can also be reprogrammed and monitored by telemetry.

Abstract: FLOTATION METHOD FOR ORIENTING CHIPS IN THE          MANUFACTURE OF SURFACE COVERING, AND RESULTING PRODUCT                    Abstract A substantially non-overlapping tightly packed layer of plastic chips is formed and attached to the surface of a substrate by a method in which the chips are dispersed onto the surface of a liquid, flowing from a first location to a second location.  The rate of flow of the surface of the liquid is reduced at the second location to cause the chips to pack together in a single-chip-thickness layer.  The layer of chips is then removed from the liquid by passing a porous web upward at an angle from below the liquid surface through the chip layer-liquid interface.  The chip layer is then transferred to a heat-sensitive transparent adhesive coating on a suitable prepared substrate and secured thereon by means of heat and pressure.  A resinous wear layer which is transparent after fusion is then applied.          Prior to fusion of the wear layer, it may be passed beneath a smoothing blade or, if a more embossed surface texture is desired, beneath an air knife to move some of the resinous wear layer material from between the chips onto the surfaces thereof.

Abstract: PACKER FOR SEALING LATERAL LINES          ABSTRACT  An  apparatus is disclosed for detecting leaks in,  for instance, sewer pipes at the vulnerable point where a branch pipe meets the main pipe.   The apparatus includes a packer member which travels along the main pipe by remote control. A T.V. camera assists in locating a branch pipe.   When the travelling packer is correctly located, the operator inflates two bladders on the traveller, one either side of the branch,  so as to seal off and contain an area between the bladders, the branch being located in this area.  The operator  (remotely)  rotates the packer  with  respect  to  the bladders  until a slot in the packer is orientated to the branch.          The  packer includes an inflatable tube that lies coiled about  a shaft  in  the  packer.   Under operator  control,  the  tube  is inflated,  which causes it to elongate.   The shaft is rotated at the  same time so that as the tube elongates,  and  stiffens,  it enters  the  branch.   The remote end of the tube  forms  a  seal against the inside of the branch.   Thus,  the area of the branch near  the  junction  with the main pipe is also included  in  the sealed off area between the two  bladders.   Now,  leak-detecting fluid can be pumped into the sealed off space: if the pressure of that  fluid  drops,  then a leak is present,  and in that case  a sealant fluid is pumped into the space.  Afterwards, the tube can be deflated and retracted,  the bladders also deflated,  and  the traveller  repositioned  at  the  next  branch.   The  disclosure includes  a  method of detecting and sealing leaks,  in which  an inflatable  tube is used to provide a means to enter  the branch, and to seal the branch away from its junction with the main pipe.

Abstract: This invention relates to a method and apparatus for removing hot volatiles and moisture from particulate plastic material being fed for injection or extrusion molding by a plasticizing screw which rotates in a heated barrel. Flow control means, such as a conveying screw or rotary valve,drop the particulate material downward through a vertical feed passage extending to an opening in the barrel. At the same time, suction is applied to remove hot volatiles which are released through the opening in the barrel as the particulate plastic material is gradually melted as it is compressed by the screw. The rate of feed of the particulate material is restricted so that the barrel of the plasticizing screw is only partially filled near the opening, thereby improving the withdrawal of the gases from the barrel. The incoming particulate material is preheated by a continuous flow of hot air through it as it passes through a tubular guide member. The air flowing to the preheater passes through a heat exchanger where it recovers some waste heat from the hot gases withdrawn from the barrel to improve efficiency and reduce power costs.

Abstract: ABSTRACT OF THE DISCLOSURE          There is disclosed an apparatus for providing passive motion compensation at the ship-riser interface of a rise-moored  floating production system or oil storage tanker, with its associated equipment including a riser handling system. Normal production proceeds, while ship motions are isolated from the riser, preventing excessive load transfer or unaccept-able dynamic effects.  The main feature of the system is its ship-borne installation, with all moving parts clear of the waterline.  The system is totally self-contained, with motion compensation, riser pipe and handling equipment on board.  By installing the flotation within the hull of the ship, it moves with the ship, thus avoiding significant inertial and weather-related load    The design is flexible.  The range of seas can be extended by adjusting the basic parameters:  float shape and size, tank depth, liquid S.G., counterweight size, link geometry, bridge length, etc.

Abstract: ABSTRACT            A heat shrinkable covering in the form of a sheet which is heat shrinkable in a longitudinal direction, and a stiffening member connected at each of two longitudinally spaced transversely extending superimposable zones of the sheet.  One stiffening member has holes and the other studs in the form of arm portions which are insertable through the holes to secure the stiffening members together.  The arm portions can be flattened down onto the outside of the covering to retain the stiffening members together while reducing risk of the studs interfering with items such as cables adjacent the covered article.  Preferably the studs have a resiliently compressible head portion which snap fits into holes formed through the sheet adjacent the holes in the stiffening member to facilitate locating the overlapped zones of the sheet relative to one another.  In use, the sheet is wrapped around an article, the stiffening members are engaged together, and the sheet is then heat shrunk.  The stiffening members support the juxtaposed edges of the sheet at points intermediate the coupling points, thus resisting the tendency for the edges of the sheet to separate as a result of the hoop stresses generated in the sheet on shrinking.
