Abstract: Clips that engage with special top flanges on elongated U-shaped acoustical baffles. One clip form suspends the baffles from grid tees in horizontal or inclined orientations or from cables or rods. Another clip form aligns to and joins intersecting baffles.

Abstract: The present invention relates in general to a suspended ceiling clip and method of using the clip to support a grid-work of channels in a key lock concealed grid suspended ceiling system. The suspended ceiling clip is used for mounting a furring channel to a top cross rail. The clip comprising a longitudinally extending base; a pair of flanges extending downwardly from the base and between which the base is located; a pair of hooks on each flange, each pair of hooks adapted to releasably connect to the furring channel; at least one projection in each flange, each projection engaging with a surface on the top cross rail to secure the clip within a longitudinal slot of the top cross rail; and wherein the air of flanges extend a predetermined distance from the base so as to space apart the top cross rail and the furring channel to provide a void therebetween.

Abstract: A pneumatic fuel distributor for solid fuel boilers is described incorporating in various embodiments one or more of the following features: a converging nozzle section, a converging adjustable orifice section and an integral trajectory plate. The nozzle, orifice and trajectory plate are preferably all interconnected and rotate together about a common axis. The orifice damper is, in one embodiment, a rotating convergent section and independently adjustable. The unit preferably incorporates a viewing glass and access port and the rotating components are preferably removable for maintenance. The unit is preferably reversible for left or right hand installation and the trajectory plate is easily replaceable.

Abstract: An apparatus for combustion of biomass is provided. The apparatus generally includes opposingly paired sidewalls, a fixed panel traversing the opposingly paired sidewalls, an actuatable panel opposite the fixed panel, and a fuel platform supported by a panel of either of the panels. A portion of the fuel platform is reversibly receivable through a portion of a panel opposite the panel supporting the fuel platform in furtherance of fuel conditioning upon actuation of the actuatable panel.

Abstract: A combustion furnace for solid fuel, including combustable fuel, wherein the furnace is arranged with a grate (11) with openings (12) which are situated for supply of air or another gas mixture for combustion. A first and second rod feeder (1, 2) is provided which includes parallel bars (3a, 3b; 4a, 4b) with intermediate carriers (5, 6). The rod feeders (1, 2) are arranged to be moved back and forth on the grate (11), independently of each other. The openings (12) are surrounded by spacers (13) carrying rails (14) in such a way that slots (15) are formed between the spacers (13) and the rails (14), so that the air has a direction out onto the grate (11) which is parallel with the rail (11).

Abstract: A foldable bed assembly includes a mattress, a mediate supporter, a front frame having a first end pivotally connected to the mediate supporter, and a rear frame having a first end pivotally connected to the mediate support. A positioning plate has a first end pivotally connected to the front frame. A rear frame has a first end pivotally connected to the mediate supporter. A front leg structure includes an upper portion pivotally connected to the second end of the front frame. The front leg structure further includes a base portion securely located on the ground. A rear leg frame is securely attached to the second end of the rear frame. A handle includes a first end pivotally connected to one of the front frame and the rear frame. When the bed assembly is in an extended status, a second end of the positioning plate engages with a peg on the upper portion of the front leg structure, and a second end of the handle engages with an engaging member on the front frame.

Abstract: The invention provides a magnetic toner for electrophotography in which an ultrafine particle form of titanium oxide (having a specific surface area of 80 to 120 m.sup.2 /g, a degree of hydrophobicity of 50 to 80% by weight, and an alumina content of 0.4 to 1.1% by weight) made hydrophobic on its surface with an aluminum compound of a fatty acid, and a hydrophobic silica are externally added onto a magnetic toner particle, and which can provide images of high density and high quality over an extended period, with no filming observed on a photosensitive material. The invention also provides a developer for electrophotography in which 10 to 40 parts by weight of a carrier particle are mixed with 100 parts by weight of a magnetic toner wherein an ultrafine particle form of titanium oxide (having a specific surface area of 80 to 120 m.sup.2 /g, a degree of hydrophobicity of 50 to 80% by weight, and an alumina content of 0.4 to 1.

Abstract: This invention relates to the combustion of metal-containing scrap rubber such as used tires in a combustion chamber equipped with a traveling-grate stoker without allowing binding of molten metal to the stoker for effective utilization of scrap rubber as a fuel for a boiler or the like. On the traveling-grate stoker of the combustion chamber, which travels from a rear part to a front part of the chamber, blocks of coal supplied from a coal feeding port in the front wall of the chamber is cast by a spreader into the chamber to form coal deposits in a substantially uniform thickness on the stoker for combustion. At the same time, scrap rubber is fed from a chute discharging into the combustion chamber through a side wall defining the chamber via a rotary valve built into the chute in adequate amounts and burned on the ash zone formed by already burned coal on the traveling-grate stoker.

Abstract: The printer has a plurality of printing rings each rotatably supported by a swingable layer pivoted about a pivot axis so as to be swung in an arcuate path around the pivot axis while it is rotated by a driving source about its own axis so that the printing rings are selectively swung toward and against a platen upon receipt of printing character selection command from the control circuit of the printer so as to print onto a paper held therebetween when the selected one of the characters on the respective printing ring is brought to a position for the printing during the rotation thereof.
