Abstract: A porous ceramic filter having one or more coatings of elemental or compounds of iron, manganese, aluminum, titanium, or mixtures thereof deposited on the surface of the pores.

Abstract: An airborne, gas particle counter, includes an inflow multiple stage turbine pump inducing flow through a particle counter. The turbine pump includes a rotor and stator assemblies and establishes gas flow through a second housing, which defines a view volume where particles are counted by light scattering or obscuration of a beam intersecting the light flow path. Intersecting rotor and stator assemblies limit particles to those suspended in the gas flow. The pump assembly includes integral flow paths limiting the need for external tubing.

Abstract: A variable width bariatric bed including a frame having a modular configuration with front end, rear end and middle frame sections that are detachable from one another to facilitate storage, transport and relocation through narrow entrances. A series of electric motors carried by the frame apply pushing forces to raise a plurality of mattress support deck sections to adjust the contour of a mattress. Each of the mattress support deck sections has a pair of pull out extensions that are adapted to slide outwardly and in opposite directions from a retracted position to an extended position at which the mattress support deck sections have a relatively wide width to support a correspondingly wide (e.g. 48 inch) mattress. Such mattress includes a mattress body and a pair of (e.g. foam or air filled) mattress extensions that are releasably connected at opposite sides of the mattress body and seated upon the pair of pull out extensions of the mattress support deck sections.

Abstract: A pump establishes gas flow in a particle counter. A pair of shafts having lobes is mounted in a first housing and serves to establish a gas flow path through a second housing which defines a view volume where particles are counted by light scattering or obscuration of a beam intersecting the light flow path. The lobes of the first housing do not contact each other or the walls of the housing, thereby limiting particles to those suspended in the gas flow.

Abstract: A cleaning composition for example in the form of a bar comprises at least 10 wt % fatty acid soap and at least 5 wt % non-soap detergent active wherein at least some of the said soap is in the delta phase. The non-soap detergent can for example be acyl isethionate. The presence of delta phase soap improves the properties of for example the bar comprising the composition. The composition can be made by subjecting to high shear energy a mixture maintained at a temperature of less than 40.degree. C. and containing at least 10 wt % fatty acid soap, at least 5 wt % non-soap detergent active and sufficient moisture to ensure the generation of at least some soap in the delta phase.
