Title: Tensioner for roller blind or screen - has tubular core and shaft coupled by tensioning spring and drum wheel on shaft for e.g. tape with looped tensioning cables
IPC: E06B9/68
Filed: 1983-07-20
Abstract: The tensioning mechanism for a roller blind or screen (1) comprises a tubular winding core (2) rotatable relative to a coaxial shaft (7) and coupled to it via a tensioning coil spring. The shaft ends are rotatably carried in bearings (8,9). The shaft carries a winding drum (5) to take-up a tape (12) as the screen is unrolled (X) and vice versa. - The other end of this tape is secured to two cables (13) which are looped around pulleys (14) and have their other ends secured to screen guide blocks (11) at the ends of a rail (10) along the free edge of the screen. The screen can be operated via a hand crank or a motor drive, with a tooth belt looped around a toothed wheel and having its ends secured to a single looped endless cable (13). FL.(2/3)

Abstract: Abstract of the Disclosure A process for the continuous coking of peat, bovey coal, wood and the like, in particle form.  Dried particles are fed into one end of a reaction chamber, stirred, and coked in the reaction chamber by heating them with hot gases, and the coked particles are removed at the other end of the reaction chamber for the purpose of cooling.  The hot gases are fed in the reaction chamber over the particles to be coked in order to achieve a direct heat exchange contact between the gases and the particles.  Preferably the hot gases are contacted counter-currently with the upper surface of the particle bed moving through the reaction chamber and the reaction chamber comprises a cylindrical furnace which is rotated around its longitudinal axis to stir the particles and to move them forward in the form of a bed.

Abstract: Abstract Non-conductive substrates are prepared for electrostatic pre-treatment with a conductivity-improving composition.  In one embodiment of the invention, the composition comprises an alkali metal hydroxide (less than 5 weight %) and a solvent system for the alkali metal hydroxide comprising a lower alkanol and a hydro-carbonaceous co-solvent.  Production line electrostatic coating techniques can be used, and the residual solvent system does not generally have an adverse effect upon adherence of the coating to the substrate. Another embodiment of the disclosed process com-bines preparatory biocidal treatment, water repellency treatment, and electrical conductivity treatment "in-line" with electro-static spray coating of wooden articles.  The preparatory treat-ment can be a single step, e.g. immersing a continuously moving line of wooden articles in a treatment bath containing a solution especially designed for this process.  The solution is very low in solids (e.g. less than 20%, preferably less than 10%), and the solvent for these solids contains some polar solvent.

They have a wide spectrum of anti-bacterial activity.         The above compounds can be produced from amino-deoxybutirosin A by the sequence of reactions which comprises protecting the five primary amino groups by converting them to arylmethoxycarbonyl derivatives, converting the 3',4'-hydroxyl groups to an acetal, acylating the remaining four hydroxyl groups,and hydrolyzing the acetal to produce a key intermediate which is an 0-2,6-dideoxy-2,6-bis[[(arylmethoxy)-carbonyl]amino]-.alpha.-D-glucopyranosyl-(1?4)-0-[2,3-di-0-acyl-5-deoxy-5-[[(arylmethoxy)carbonyl]amino]-.beta.-D-xylofuranosyl-(1?5)]-6-0-acyl-N1-[(S)-2-acyloxy-1-oxo-4-[[(arylmethoxy)carbonyl] amino]-butyl]-2-deoxy-N3-[(arylmethoxy)carbonyl]streptamine, generically also identified as protected 5"-aminodeoxy-butirosin A.  That compound is reacted with methanesulfonyl chloride in pyridine to introduce 3',4'-methanesulfonyloxy groups which are removed by reaction with zinc and sodium iodide to introduce a double bond at the 3',4' position.          The acyl groups are hydrolyzed or cleaved as by reaction with ammonia in methanol and the product is reacted with hydrogen in the presence of a catalyst to remove the arylmethoxy-carbonyl groups and hydrogenate the double bond with the formation of aminotrideoxybutirosin A.                           -1a-

Carburetor has throat and fuel spray tube extending into   throat to receive and discharge fuel into throat.  Valve assembly has first and second sliding gate valve members which cooperate with fuel spray tube as they slide transversely across throat between closed and wide open positions.  Valve actuating means, such as rack and pinion or link and arm mechanism, couple valve members together to move them equal amounts in opposite dir-ections.  Fuel metering means preferrably coupled to valve members meters flow of fuel through spray tube in amounts proportional to valve opening.  In one embodiment fuel spray tube has air bleed and discharge jet means spaced along tube, the jets being closed by valve members as valve members appraoch each other.  Air bleed jets admit portion of ram air into manifold within fuel spray tube for primary mixing to form rich mixture, which then discharges from spray tube into throat for further mixing with air flowing past fuel spray tube to produce desired leaner mixture.  In one embodiment spray tube is parallel to movement of valve member, in second embodiment it is normal to movement of valve members. In further embodiment, fuel spray tube extends to middle of throat and is enclosed by one valve member in sliding fit. Tapered fuel needle extending from other valve member meters fuel by restricting flow through central passage of tube.

During normal debarker operation the rotor pres-sure chamber is isolated from an external source of air pres-sure. Air is supplied to the rotor pressure chamber inter-mittently only when necessary to maintain or increase air pressure in the chamber through a pilot air-operated ring-type air seal between the rotor and its stator. The seal is loaded only during the addition of air to the rotor pres-sure chamber to minimized wear on the sealing surfaces. Positive, instantaneous opening and closing of the tools and changes in air pressure in the rotor pressure chamber are effected from a remote operators's console while the rotor is either rotating or stationary.

Abstract: IMPROVED LIVE-TANK MODULAR-CONSTRUCTION       HIGH-VOLTAGE COMPRESSED-GAS CIRCUIT-BREAKER ARRANGEMENTS              ABSTRACT OF THE DISCLOSURE    An improved live-tank modular-construction circuit-breaker arrangement of the rotating-contact-arm type is provided, in which only three breaks are adequate and suffice for interrupting very high voltages, say of the order of 550 kV, or 362 kV, for example.  The metallic interrupting "live" heads are of modular standard construction, and utilize the rotating-contact-arm type of circuit-breaker assemblage.         The proposed breaker design of the present inven-tion allows interruption to take place with an odd number of breaks in series for "live-tank" breakers.  This results in eliminating three extra-high-voltage terminal-bushings, three capacitor dividers, three interrupting breaks, and three closing resistors in the opening or closing operations for preventing switching surges (overvoltages), which would otherwise be required.  Cost reduction has thereby been tremendously reduced by the elimination of the aforesaid major circuit-breaker components.         In one modification of the invention, one of the "live" metallic interrupting heads encloses only a single break, whereas the other interrupting head may utilize an interrupting "live" head construction of the usual type, involving closing resistances inserted only during the clo-sing operation, or, alternatively, the other, or "second" series interrupting head may use only one closing resistance with the accompanying break within the interrupting head having only a pair of main contacts, with the elimination in connection with this particular break of a shunting in-rush resistance and its associated insertion-resistance separable contacts.         The aforesaid two-unit construction enables the use of the usual circuit-breaker operating mechanism and mechanical linkage components involving standardized parts and thereby permitting ready assembly.
