Abstract: An apparatus is provided for femoral artery compression having an inflatable bladder, a cooling member and a rigid panel disposed within a sterile envelope and securable to a patient about the wound site via a detachable strap. The envelope can be pre-cooled as a unit and located over the wound such that the rigid panel focuses compressive force against the artery, trapping it between the panel and the pelvic bone rim. The bladder is adjustably inflatable by a conventional squeeze bulb valve arrangement and forces the cooling member against the rigid panel and the tissue in the wound vicinity. The rigid panel includes ridge structure to restrict sliding movement with respect to the cooling member. The envelope includes separate chambers for each of these components so as to restrict their movement once the envelope has been properly positioned. The envelope and its components are preferably constructed from inexpensive materials such that the entire apparatus is conveniently disposable after a single use.

Abstract: In a process of making gas laid products by entraining particles at least partially coated with a binder in a gaseous stream, passing the stream through a forming chamber and through a permeable collecting surface where the particles build up to form a product like fiber glass insulation, this invention prevents particles from contacting and building up on the walls of the forming chamber and causing wet spots in the finished product by maintaining a high velocity, high pressure layer of gas close to the exposed surface of the walls of the chamber and moving in the general direction of the gaseous stream. This is accomplished by apparatus including a plurality of plenum boxes forming the walls of the forming chamber with the surface exposed to the gaseous stream having gas directing openings therein. Also, an improved method of applying the binder to the particles is disclosed.

Abstract: A packaged lumber-dipping apparatus comprises a dipping tank of lumber-preserving fluid, a submersible roll case section supported by a hoist mast for lowering a package of lumber into the tank, and infeed and outfeed conveyors. A clamp is mounted on the hoist mast for clamping the package down on the roll case section so that the lumber will not float when submerged in the tank. The infeed conveyor is positioned at an end of the roll case section for feeding a package of lumber lengthwise onto the roll case section. The outfeed conveyor, positioned alongside the tank, receives the package of lumber from the roll case section after dipping. Two tiltable skate roll sections in the roll case section, connected by chains to the clamp, tilt toward the outfeed conveyor when the clamp is raised to unload the package onto the outfeed conveyor after dipping.

Abstract: A machine for forming mineral fibers into mats or blankets comprising a plurality of modules each including primary fiber formers, fiber attenuation means, binder applicators, and fiber collectors to produce continuous lengths of mat. A common conveyor is adapted to receive the mats of each module at spaced mat receiving stations along its length. The common conveyor receives the uncured mats in juxtaposition to each other and conveys them to stations for further processing. Each module is adapted to operate and be taken off or put on line without disruption of the operation of the other modules. Each includes a scrap conveyor for primary fibers, a fiber collection conveyor cleaning means for the conveyor and a suction box all of which are shielded from the common conveyor to avoid contamination of the mat on the common conveyor.
