Patent EP-0002196-A1 (EP)
Inventor: HERGENROTHER WILLIAM LEE
IPC: C08G8/38
Filed: 1978-11-07
Abstract: Polymers of anionically polymerized monomers such as mono-olefins, conjugated dienes, vinyl substituted aromatics, vinyl substituted pyridine, vinyl substituted quinolines, various aldehydes, various epoxides. various oxetanes, various oxygen-containing compounds, and the like are produced and end capped witb a polyisocyanate. or polyisothiocyanate having the formula R(N=C=X) n  wherein R is a hydrocarbon, n is 2 or 3, and X is oxygen or sulfur. Such end capped polymers, of course, contain one reacted or connected isocyanate or isothiocyanate group and at least one free isocyanate or isothiocyanate end group, which free end group(s) reacts with an amide to give an imide end group. The imide terminated polymer is then hydrolyzed to form a stable amine terminated polymer. The reaction of the amide compound with the isocyanate(s) or isothiocyanate(s), followed by hydrolysis, results in the replacement of the free isocyanate or isothiocyanate end group(s) with an amine group(s). Thus, the amine terminated polymer contains the polymer connected to an isocyanate or isothiocyanate group (now an amide group or a thioamide group), which in turn is attached to the hydrocarbon portion, that is, the "R" portion of the polyisocyanate, which in turn is connected to the formed amine group. The amine terminated polymers may be stored extended periods of time and then reacted with various polymers, prepolymers, monomers, or various combinations thereof to form various block or graft copolymers. That is, the amine terminated polymer may be subsequently reacted with any amine reactive compound such as diepoxy monomers or an epoxy prepolymer in the presence of known epoxy catalysts to give a blocked epoxy copolymer. Similarly, the amine terminated polymer may be reacted with urea prepolymers or urea-forming monomers to yield a block urea copolymer. Reaction of the amine terminated polymer with urethane polymers, urethane prepolymers, or urethane-forming monomers will yield a urethane block copolymer. Reaction of the amine terminated polymer with urethane-urea prepolymers or urethane-urea forming monomers will yield a urethane-urea block copolymer. Similarly, various dianhydride and diamine monomers may be utilized to form an imide block copolymer.

Inventor: GOODMAN CHARLES HOWARD LUDLOW
IPC: H01L29/201
Filed: 1978-12-19
Abstract: In (Sb o,1 As 09 ) light emissive diodes and lasers are grown on Ga Sb substrates to give lattice matching. Ga Sb has higher band-gap, high refractive index therefore gives electrical, but not optical, confinement required for laser action. Both confinement types provided by sandwiching active layer between layers of (Al 0.6 Ga 0.4 )Sb. In (Sb 0.1 As 0.9 ) emits at approximately 4 µm, but emission can be shifted by increasing the proportion of In Sb and restoring the lattice match by the addition of another compound semiconductor e.g. Ga As for longer wavelength emission of In P or Al As for shorter wavelength emission.

Abstract: A partial opening patch top closure member 6 of a composite container, including a body portion mounted on one end of the container and a pull tab portion 4 connected with one edge of the body portion, is characterized by the provision of a tear-initiating cut 8 in at least one of the junctures between the pull tab and body portions, whereby the tab portion may be pulled to tear a removable portion from the body portion, thereby defining a dispensing opening in the residual body portion. In the preferred embodiment, a single tear-initiating cut is provided in one juncture between the body portion and an asymmetrically or symmetrically arranged pull tab portion that is pulled laterally to tear the removable body portion for the residual body portion. In a second embodiment, the patch top closure member includes a symmetrically arranged pull tab portion which defines a pair of junctures each having a tear-initiating cut, whereby upon pulling the tab upwardly, the pull tab and removable portions are torn away from the body member along converging lines of tear. One or more score lines may be provided in the body portion of the closure member to more accurately define the lines of tear. A plastics overcap may be provided. <IMAGE>

Abstract: The present invention provides a valve which can be easily operated by an actuator member (39) which can be released or utilised for other functions. Spaced apart dogs (26, 37) carried by the valve member (31) are resiliently biassed to alternately cooperate with one of two spaced apart grooves (32, 33) provided in the valve body (23), to position the valve member (31) alternately in an open and a closed position. Confronting shoulders (36b, 37b) of the dogs (36, 37) are engageable by a flange (38) on the actuator member (39) when a dog (36, 37) is retracted from a groove (32, 33), to thus shift the valve member (31) with reciprocation of the actuator member (39). Each of the dogs (36, 37) releases the actuator member (39) as the dog (36, 37) enters its cooperating groove (32, 33). Thus the valve can be remotely operated without requiring a permanent connection to a remote location e.g. well head.

Abstract: A photoflash unit having a plurality offlashlamps (11-15, 21-25) mounted on a printed circuit board (43) containing circuitry for sequentially igniting the flashlamps in response to successive firing pulses applied thereto. The circuitry includes a plurality of solid-state switches (71-74) capable of being activated by radiant energy generated during flashing of lamps located adjacent to respective switches (71-74). Initially, each of the switches has a resistance sufficiently high to provide an open circuit to the applied firing pulses, and after being activated by radiation, the switch undergoes chemical conversion to a conductive state over a finite time interval. The switches are prepared from compositions comprising admixtures of silver carbonate and / or silver oxide, silver-coated glass beads and a binder; the admixtures may also include electrically non-conductive particulate solids, such as titanium dioxide, and/or silver-coated metal beads. The constituents and proportions of the switch compositions are selected to provide a predetermined conversion time of twelve milliseconds or greater, thereby permitting reliable functioning with comparatively long duration, low voltage firing pulses.
