Abstract: FABRICATING INTEGRATED CIRCUITS INCORPORATING    HIGH PERFORMANCE BIPOLAR TRANSISTORS          Abstract A method and resulting semiconductor device which utilizes a mesa emitter structure in a silicon body.  The mesa emitter is formed in the silicon semiconductor body and then passivated on its sidewalls using a suitable dielectric.  The base region is formed both under the mesa emitter and adjacent thereto.  The emitter-base junction is substantially in one plane and substantially without a sidewall component.  Contacts are provided to the emitter and to the base region surrounding the mesa emitter.  The resulting structure is such that a base contact can be within a few thousand angstroms of the intrinsic base region.

Abstract: ABSTRACT OF THE DISCLOSURE     The chuck of an electric drill mounts an annular collar which may be fitted to the rotary actuator of a twist top dispenser cartridge for caulking or the like.  As the drill is operated, the chuck  rotates the collar which turns the rotary actuator thus dispensing the cartridge con-tents.  By preference, the adapter of which the collar is a part incorporates a clutch which permits the user to initiate and terminate dispensing, without releasing the trigger of the electric drill, by manipulating the cartridge relative to the electric drill.

Title: Melt processable thermotropic wholly  aromatic polyester
Inventor: CALUNDANN GORDON W
IPC: C08G63/60
Filed: 1978-08-23
Granted: 1982-05-18
Abstract: ABSTRACT OF THE DISCLOSURE A wholly aromatic polyester is provided which unlike the aromatic polyesters normally encountered in the prior art is not intractable or difficultly tractable and readily undergoes melt processing with ease.          The aromatic polyester of the present invention consists essentially of the recurring units (a) p-oxybenzoyl moiety, (b) 2,6-dioxynaphthalene moiety, and (c) terephthaloyl moiety, and is free of units which possess ring substitution.  The resulting polyester exhibits a melting point below approximately 325°C., preferably below 300°C., and most preferably below approximately 290°C.  The ability of the wholly aromatic polyester to readily undergo melt processing can be attributed to its atypical inherent propensity to form a thermotropic melt phase at relatively low temperatures.  The wholly aromatic polyester may be formed by a variety of procedures including a slurry polymerization technique (as defined) or a melt polymerization technique.

Abstract: ABSTRACT OF THE DISCLOSURE      Spherulites grow in such sections as neck, neck and, bottom center or bottom periphery of a hollow bottle-shaped container of biaxially orientation-blow molded polyethylene terephthalate where the the resin is not substantially subjected to orientation, thereby to improve the thermal resistance, stiffness and content resistance of such sections to almost the same extent as the biaxially oriented sections of the container such as shoulder and cylindrical sections thereof.  The aforesaid sections of the preformed piece before being blow-molded or of the blow-molded container where the resin is not substantially subjected to orientation are first heated at 120 - 180°C for 3 - 8 minutes and, then, annealed at room temperatures, with a result that such sections have a suphrulite texture of an increased density and are opacified in white or milky white.

Abstract: ABSTRACT An individual section of a multiple section glassware forming machine has three operating stations in spaced apart relation along the longitudinal centre line of the section. Three independently operable transfer means move, respectively, a parison formed at the first station to the second station, a further formed parison from the second station to the third station, and an article of glassware from the third station to a takeout position over a deadplate.  The operating speed and rate of acceleration of each of the three transfer means is selected independently of the operating speed and rate of acceleration of both the other transfer means to effect its movement in the shortest practicable time compatible with the state of the glass during the movement of that transfer means.

Abstract: ABSTRACT OF THE DISCLOSURE           A prebuilt fireplace construction for instal-lation in a living space includes a housing, a firebox within the housing with an open forward side adapted to be sealed by glass doors, an outlet for combustion gases, an inlet for combustion air and has a base structure sup-porting the housing through which an inlet duct for com-bustion air extends.  One end of the combustion air duct is connected to the combustion air inlet.  The other end of the duct may connect to an optionally used air intake conduit so that exterior air may be delivered to the com-bustion air inlet, or receive air from a room interior which is drawn into the firebox through the base structure.          A damper within the duct permits adjustment of external air flow into the firebox from either source and can be positioned to close the combustion air duct to prevent drafts when the fireplace is not in use.

Abstract: ABSTRACT OF THE DISCLOSURE       A machine for producing chenille yarn has a winding member on which turns of effect yarn are formed.  A rotating disc-shaped cutter can be moved into an operative position to cut the turns on the winding member into individual lengths of effect yarn for forming conventional chenille yarn.   The cutter can also be moved to a non-operative position remote from the winding member whereby the turns of effect yarn are uncut and the chenille yarn then produced is of the boucle type.  The cutter maybe moved between its operative and inoperative positions during operation of the machine so that the yarn produced has alternate chenille portions and boucle portions.
