Title: Method and apparatus for controlling a single-or polyphase a.c. controller
Inventor: RUNGGALDIER DIETHARD
IPC: H02P27/02
Filed: 1990-01-19
Abstract: In the case of controlling AC voltage converters by means of phase control by semiconductor valves (6), the triggering signals must, on the one hand, be sufficiently long to ensure reliable triggering and, on the other hand, sufficiently short to avoid an overload of triggering amplifiers (12). The invention therefore provides for the use of triggering signals (ZZ) with a variable time length, which end at least approximately when the current flowing in the triggered phase increases again. Devices for carrying out the method are also specified.

Title: Locking y-connector for selective attachment to exterior of medical tubing
Inventor: BERRY GAYLORD L
IPC: A61M39/00
Filed: 1990-10-17
Abstract: ABSTRACT     A connector for applying to the exterior of an elongated member of circular cross-section circumferentially uniform radially  directed  compressive  forces  by which  to  effect attachment  and  fluid-tight  sealing  thereagainst.    The connector  comprises  an  attachment  fitting  having  formed therethrough a bore for slidably receiving the elongated member and a coaxially disposed, radially enlarged compression recess communicating therewith.  A flexible annular gripping member resides in the compression recess slidably circling the elongated member.  A locking hub disposed at the end of the compression recess remote from the bore has a compression face which extends into compression recess.  The locking hub is longitudinally slidable relative to the attachment fitting between a disengaged position in which the elongated member is slidable relative to the gripping member and an engaged position in which the compression face bears against and deforms the gripping member to preclude sliding of the tubing relative to the gripping member by urging the gripping member into radial engagement with the portion of the tubing in the compression recess.  A retention pin and cooperating retention slot on opposed portions of attachment fitting and the locking hub secure the locking hub in its engaged position.   The connector has specific utility in terminating the proximal end of a coaxial lumen tube assembly used to interconnect an implanted  extrapulmonary  blood  gas  exchange  device with extracorporeal support equipment.

Title: Ellipsometric control of material growth
Inventor: ASPNES DAVID E
IPC: H01L21/203
Filed: 1991-01-21
Abstract: Abstract of the Disclosure A method and apparatus for controlling the growth of a multi-species film. During the film growth, an ellipsometer(40,52,54,62,64,70,72) continuously monitors the surface(24) on which the film is growing. The ellipsometer data is used to calculate(38) the effective complex dielectric constant of the thin-film/substrate structure. A sequence of such data is used in a model calculation to determine the composition of the top portion of the thin film. The measured composition is compared with the target composition and the amount supplied of one of the species is correspondingly changed(26).

Patent CA-2050234-A1 (CA)
Inventor: JOBIN LUC
IPC: A01M1/20
Filed: 1991-08-29
Abstract: The invention relates to a portable luminous trap for flying or crawling insects. A fluorescent lamp in the center of an insect ingress zone attracts the insects. Transparent baffles radiating outwardly from the lamp act as walls and an insect hitting a baffle is stunned and drops downwardly, through a funnel opening into an entrapment container therebelow. The funnel also helps prevent escape of still-living insects from the container. An alkaline dry cell battery powers the lamp, test circuits for the battery and the lamp, and a clock circuit. A photocell is used to activate the trap at dusk and the setting for the clock circuit determines the length of time that the lamp is activated each night.

Title: Roofing shingle
Inventor: HANNAH MARCIA G
IPC: E04D1/28
Filed: 1991-11-06
Abstract: A roofing shingle is provided for shingling a roof with overlapped shingles, wherein the exposed portion of the shingle is selected to be of a height in the installed condition relative to the overall height of the shingle that enhances material utilization, to be at least approximately 44.4% efficient. This is accomplished by using an exposure height of 8 inches relative to an overall shingle height of 18 inches. The shingles are preferably constructed to have either 3 or 4 tabs, thereby having a ratio of exposure height to tab width of either 0.667 or 0.889, respectively. A larger exposure allows one to obtain 200 shingles for each 300 lineal feet of sheet shingle material, when the shingles have 18 inch overall height, and further allows an overall saving in the number of nails required to install a roof.      The invention also contemplates variations in tab width within a given shingle and variations in number of tabs from about one to nine tabs in a given shingle.
