A diffuser housing and a nozzle housing are attached to the impeller housing, which is supported by a transom. An intake duct is disposed in front of the impeller housing. The intake duct has an intake opening, the perimeter of which is defined by a forward edge portion substantially flush and a rear edge portion raised relative to the remainder of the edge, which is substantially parallel to the perimeter to the forward edge. A sloped surface connects the raised rear edge and the lowest point of the transom. The intake duct has a forward facing separator baffle depending from and substantially parallel to the wall and disposed interiorly thereof. The space defined between the separator baffle and the wall is in fluid communication through at least one discharge duct to either one of the transom and bottom.
Abstract: A support device for the mechanical handle of a paint roller. This support, made by molding of a plastic material, comprises a handle divided lengthwise in two parts joinable together by a locking mechanism. The handle is articulated on a stirrup which supports the cylindrical handle, and which is able to rotate to 90 degrees, from a position parallel to the stirrup to a position perpendicular to the stirrup. The parts of the handle articulate themselves on the stirrup by the intermediary of molded bridges on a stud projecting centrally from the stirrup.
Abstract: A method for reducing green roughness of a braking system and a method of manufacturing a brake system includes coating at least one of the components of the brake system with a boundary layer material. The method is applicable to either the pad of a disc brake system or the brake drum lining and/or the brake shoe of a brake drum system. The coating is either a binder, a filler, a boundary layer lubricant or a mixture thereof. The coating hereof is either graphite, molybdenum disulfide and/or a divalent fluoride, either organic or inorganic. Likewise, a thermoset paint such as an alkyd resin, phenolic resin, epoxy resin or the like can be used for the coating material. The coating eliminates uneven transfer of friction material during the brake wear-in period which creates brake torque vibration which, in turn, increases vehicle sensitivity and brake roughness.

Abstract: Sand cores are broken up and removed from castings, particularly from cylinder heads from internal combustion engines. A pneumatic hammer is applied to the casting while the casting is held against a low pressure cylinder. The casting is subjected to horizontal oscillation by a receiver actuated by a rod and a double eccentric rotatably driven by a geared motor.
Abstract: A detergent dispenser having a support for the dispenser may be filled with liquid from a suitable source. A switch controls the flow of liquid into the dispenser. The support, which may be a cradle from which the dispenser hangs or a platform on top of which the dispenser sits, holds the dispenser in conjunction with a resilient urging mechanism. The switch is activated by an empty dispenser urging against the switch. The switch is deactivated by the weight of the dispenser being filled, thus overcoming the urging mechanism.
Abstract: A device for fixing end rings in the ends of a rotary screen printing stencil wherein a layer of adhesive, which has been applied between the end rings and the ends of said stencil, is hardened by using infra-red radiation producing means such as infra-red radiators. Such radiators each have a reflector which is insulated at their back-sides. During the treatment with infra-red radiation, the assembly of end rings and printing stencil may be rotated around the longitudinal axis of the stencil.
Abstract: A sprayable coating composition is formulated using one or more acrylates and one or more photoinitiators which act to polymerize the composition when exposed to ultraviolet light. Because of the use of low molecular weight monomers or oligomers, the composition is essentially free of volatile organic solvents and therefore evaporative emissions in curing are substantially eliminated.

Abstract: A pre-tied suturing knot for use with a surgical needle for endoscopic procedures and the method for making and using the pre-tied knot for tying the suture in situ. The pre-tied knot is tied from suturing thread and surrounds the shaft of a needle holder or grasper. A needle holder is placed on the U-shaped loop and the U-shaped loop or bight is pulled back upon itself to create a first loop, a second loop and two loopholes. The distal end of the suture thread is threaded over the proximal end and through the loopholes creating the nascent knot. The pre-tied knot is utilized after the tissue has been pierced with the needle. Thereafter, the needle holder is withdrawn from the suturing site, thereby pulling the suture thread against and through the tissue edges and moving the pre-tied knot along the shaft of the needle holder over the clamp and into position near the suturing site.
Abstract: An electrically heated nozzle for use in injection molding which is positioned between an injection apparatus and a die casting machine in an injection molding operation. The nozzle transfers molten material such as metal under pressure from the injection apparatus to the die. The nozzle has a refractive core, with a flow passage, surrounded by an intermediate metal core which is heated by a coil of electrical resistance wire to prevent heat loss in the molten metal. A metal sleeve surrounds the coil and the intermediate core. The heating coil is attached to a control box which energizes the coil and controls the temperature.
