Abstract: A method of forming a preform suitable for optical waveguides is disclosed. The method comprises providing a hollow tubular member (10) defining a substantially longitudinal aperture and having one end thereof tapered and of diminishing wall thickness for the length of the taper. Adjacent the tapered end is formed an outwardly extending protrusion (16). A starting mandrel (20) is inserted into the aperture so as to extend therebeyond. Particulate material is deposited, for example using burners (40) over at least a portion of each of the extending part of the hollow tubular member (10) and the starting mandrel (20) whereby the extending protrusion (16) is embedded in one end of the resulting optical waveguide preform (44). An integral unit including the tubular member and the preform is thus formed. Means are provided for a substantially gas-tight connection to the handle so that a gaseous medium may be flowed through the handle and the optical waveguide preform in its porous soot form. Means are also provided for attaching and securing the composite structure to a source of gaseous medium.

Abstract: A gas-cooled magnetic blast circuit breaker made up of a plurality of identical modules. Each module is a flat body made of electrically non-conductive air-permeable material and is formed with an upper and a lower arc breaking chamber, the chambers being separated from one another by a central wall of the body. An electrically conductive stationary contact member is provided in each chamber, each member extending through the body for connection to the power line on opposite faces of the body. There is also provided an electrically conductive dual contact member which is pivotally mounted across the central wall of the body, this dual member having a contact gate at each end, each gate being located in one of the chambers to cooperate with the stationary contact member in that chamber. A pivotable shaft, made of electrically non-conductive material, extends transversely through the body and is connected to the dual contact member to pivot it whereby to move the contact gates simultaneously into and out of electrical junction with the stationary contact members so as to make and break current in the power line. There is provided a coil which is energizable by the current in the power line and which is adapted to create a magnetic field suitable to blow, into the arc chambers, arcs that are formed when the contact gates are moved away from the stationary contact members. The chambers are formed so as to be provided with guideways extending from outside the body to the contact members so that air may be sucked into the chamber by the blown arcs so as to cool the contact members.

Title: Compact fluorescent lamp unit having segregated air-cooling means
Inventor: BEDEL DENIS E
IPC: F21V23/00
Filed: 1983-07-19
Abstract: Convection air-cooling of a compact electric discharge lamp unit that is adapted for use as a screw-in energy-converv- ing substitute for an incandescent-type lamp bulb is enhanced by partitioning the lamp housing into two separate compartments and providing vents and connecting air passageways that direct ambient air through the respective housing compartments along two different paths thereby cooling the compartments independently of one another. A light source (such as a convolute low-pressure discharge tube) is located within one of the compartments and an electrical circuit for energizing the lamp is located in the other compartment. The "segregated air-flow" mode of cooling prevents heat that is generated by the lamp from being introduced into the compartment that contains the electrical circuit and thus prevents the circuit components from becoming overheated and possibly damaged.

Abstract: An erroneous microinstruction and related preceding microinstructions are subjected to a so-called retry operation so as to restore the microprogram-controlled unit from the error. The retry operation is carried out under an interlock mode, in which both detection of the erroneous microinstruction and correction for each microinstruction are achieved. At the same time, an address for specifying the thus detected erroneous microinstruction is recorded. When an address the same as the recorded address is next generated, the recovery from the error is performed only for the erroneous microinstruction under the interlock mode.

Abstract: A clip circuit (17) of a CRT display unit clips off, by means of a simple operation, the portion of a polygon (5) protruding from the three-dimensional space (4) when the polygon (5) is partially inserted into the three-dimensional space. More specifically, a window register (175) stores therein the data on the primary to tertiary planes forming the three-dimensional space, respectively comprised of a pair of planes. A host computer (10) provides three-dimensional coordinate data representing the respective vertexes of the polygon. An ALU (177) first extracts from the vectors constituting the polygon, a line segment existing in a field bounded by a pair of primary planes, according to the three-dimensional coordinate data from the window-register and the three-dimensional plane data from the host computer. Then, from the above stated line segment, the ALU (177) extracts a line segment existing in a field bounded by a pair of secondary planes and further extracts from this line segment, a line segment existing in a field bounded by a pair of tertiary planes, so that the other portions excluding the extracted line segments are clipped off. Accordingly, the unnecessary portions of a polygon can be clipped off only by one processing operation for each pair of primary to tertiaty planes, which means that only three processing operations are required.

Abstract: A photometric light absorption measuring apparatus includes a central processing unit sending generator frequency data to a high power generator that pulses a light source intermittently to irradiate a liquid sample contained in a transparent receptacle. The intermittent light beams pass through optical guides, focusing lenses, light amplifiers and a slit aperture. A diffraction grating disperses the light beams and a light detector receives the spectral components and generates corresponding intensity signals which are passed through an amplifier and supplied to an arithmetical unit which receives frequency power generation signals from the central processing unit. A misfire detector sends signals to the arithmetical unit when the light source fails to flash. The arithmetical unit preselects two spectral components and calculates the concentration of a corresponding preselected constituent of the liquid sample from the average mean value of the intensity differences between the two preselected spectral components corrected to eliminate intensity data corresponding to non-flashes of the light source.
