US Patent:

46128158, Sep 23, 1986

Filed:

Feb 14, 1985

Appl. No.:

6/701390

Inventors:

Dennis A. Green - Phoenix AZ
Thomas L. Purcell - Scottsdale AZ

International Classification:

G01N 114

US Classification:

7386411

Abstract:

Apparatus for sampling a material in a container both in a laboratory environment and in a field environment is shown. The apparatus includes a portable pump for generating either a partial pressure with respect to atmosphere or a partial vacuum with respect to atmosphere. The partial vacuum is used to force the material from the container through a collection tube into a specimen bottle. When the material in the container is too viscous to be directly drawn into the specimen bottle, a pressure is applied to one end of the collection tube and the material in the collection tube is driven into the specimen bottle. The footpump is modified to provide both a pressure and a vacuum nozzle and is easily portable to a remote location site.

Appl. No.:

7/345288

Inventors:

Thomas L. Purcell - Scottsdale AZ

International Classification:

B26B 308

US Classification:

30 1

Abstract:

A mold extractor and method of manufacture thereof is provided. The extractor or tool is used to remove the annular wall, bottom wall, and lid of a plastic mold container from a concrete test sample taken at a construction site for later testing in a test laboratory. The extractor includes a hammer member, a guide member and a chisel member. The hammer is reciprocally displaced by an operator for applying a downward force on the container annular wall at the wall edge. The hammer has a peripheral wall having an elongate hole with an axis through which the guide portion extends. The hammer has enlarged end portions, for gripping by the operator and for applying the impact force. The guide member is an elongated round bar portion which has a handle at the top end thereof. The chisel member has a head portion, a square bar portion, a claw portion, and a chisel end portion. The claw portion is used for lifting the container lid by applying an upward force on the extractor.
