Abstract:
A system and process for facilitating hemostasis of a puncture site in a blood vessel injects an absorbable sponge pledget in a hydrated state at an exterior of the blood vessel puncture to facilitate hemostasis. The system includes a tract dilator for locating the puncture, an introducer, and a plunger. The introducer includes a staging chamber for receiving the absorbent sponge pledget and a delivery chamber having a diameter smaller than a diameter of the staging chamber into which a hydrated pledget passes. The pledget is hydrated and compressed within the introducer and then ejected with the plunger to delivery site to facilitate hemostasis of the blood vessel puncture. The system delivers the absorbable sponge pledget over a guidewire to ensure the proper positioning of the pledget over the puncture. The implanted absorbable sponge once delivered expands rapidly to fill the target site and is absorbed by the body over time.
Abstract:
Trailer 1 has an elongate frame made up of longitudinal channels 2 and 3 and transverse members 6 and 6a. A fork-lift mast assembly 8 has a base portion including lateral members 10 carrying rollers 30 accommodated within the channels 2 and 3 so that the mast assembly may be displaced longitudinally along the length of the trailer between an extended position and a retracted position. In the extended condition, the forks 9 are located rearwardly of the frame so that they may be lowered to the ground, while in the retracted condition they are located inboard on the trailer frame, so that a load may be carried in a stable manner with its centre of gravity located between the wheels 5 and the coupling 7a. Hydraulic rams 24 and 23 control longitudinal displacement of the assembly and the raising and lowering movement of the forks 9 respectively. The upwardly-extending part of the mast may also be tilted relative to the base portion by further hydraulic rams 24.

Cleaning internally, non-rotary appliances for.-A cleaner or scraper consists of two or more helically coiled coreless strips 1, 2 flexibly connected, preferably by means cf links 3, and adapted to be drawn through the water-main or other pipe by means of a cable 5. In the construction shown, two strips coiled in opposite directions are employed.

12,293. Davis, T. May 24. Slabs.-Blocks for structural or decorative purposes are made by forming a sand bed a on a level floor b, marking out on the sand bed the structure to be formed, for instance the gable end of a house, laying on the sand rough stones g or other decorative or facing objects dividing the stones up into area i of a preferably slightly irregular shape by means of paper or tinfoil j, placing thin wooden strips k above the stones and substantially in line with the paper and finally running cement grouting m over the stones and completing the backing by means of rough finishing-cement n. After the cement backing is set, the blocks are marked for identification and removed for erection. The backing may be reinforced by metal hoops or rods.

18,331. Davis, T. Sept. 11. Crescent - shaped chamber type.-In steam or compressed-air engines of the e crescentshaped chamber type having hinged vanes pressed outwardly by springs, a part J of the casing is made concentric with the shaft E. The piston D carries three hinged vanes C pressed outwards by tangentiallyarranged spring- pressed plungers K. The inlet port is shown at B and the exhaust port at F, the latter opening as the former is closed.
Abstract:
An apparatus for dispersing material comprises a container for holding material to be dispersed, and a lid (38) movable relative to the base. A shaft (33) is rotatably mounted between the front and rear walls of the base and a plurality of dispersing members (19) are mounted on and rotatable with the shaft for throwing material held in the base through a gap (37) defined between the lid and the base. The shaft is movable in slot 28 in a substantially vertical direction to sustain generally uniform contact between the dispersing members and the material to be dispersed.
