Title: Concrete anchor
Inventor: SHINJO KATSUMI
IPC: F16B13/08
Filed: 1993-04-13
Abstract: ABSTRACT OF THE DISCLOSURE     A concrete anchor has an anchor body 21, which is a rod-shaped member 22 having a male thread 23 and a striking head 24, both formed at one end of the member.    This rod-shaped member 22 further has at its another end a cylindrical portion 25 so that slots 26 extend axially from an open end of the portion so as to provide expandible feet 27.    Saw-toothed scratching tips 28 are formed to be acute ends of the expand-ible feet.    A tapered plug 31 which is inserted in the cylin-drical portion 25 has an annular recess 34 and a retaining shoulder 36, both formed between a large diameter portion and a root 35 of the tapered plug, with the annular recess providing a cavity to receive concrete scrapings, so that an impact applied to the striking head can provide a strong and effective retention force for the concrete anchor, and any cracks which may be produced around a hole holding the fixed anchor does not impair the retention force.

Patent CA-2104539-A1 (CA)
Inventor: SOULES DAVID A
IPC: C08G75/06
Filed: 1993-08-20
Abstract: A method is provided for selectively extracting the lower molecular weight fraction of a poly(arylene sulfide) polymer by contacting the polymer with a polar organic compound and a promoter compound to form a less dense polymer-lean liquid phase and a more dense polymer-rich liquid phase, separating the polymer-lean liquid phase from the polymer-rich liquid phase, and recovering the polymer from the polymer-rich phase. Alternatively, either of the phases can be isolated and polar organic compound and optionally promoter can be added to form two new phases, followed by isolation of the new polymer-rich phase. This process can be repeated as often as desired or practicable in order to recover polymer having a desired molecular weight and/or molecular weight distribution. <IMAGE>
