Abstract: A biopsy device for obtaining tissue specimens, particularly from endocervical canal. A cutting anvil, typically of a non-metallic material such as plastic, is carried at one end of an elongated shaft. An annular cutting blade, typically of a metallic material, on the end of a hollow shaft is telescoped on the shaft carrying the cutting anvil. The device includes a locking arrangement to lock the cutting edge of the device in engagement with the anvil during insertion of the device to the selected site and during removal of same from the body so that during insertion there is no inadvertent damage to tissue and, most importantly, no inadvertent loss and spreading of possibly diseased tissue and cells during removal. Further, the device includes an adjustment means whereby the size of the specimen may be selected prior to insertion in the patient.

Abstract: A method of direct flame incineration of a polluted air effluent, such as the effluent from a coffee roasting oven. The method is employed in apparatus comprising a cylindrical housing containing three concentric longitudinally aligned shells, each of which defines a respective combustion zone, and with the outermost shell defining with the housing an effluent heat exchange passageway to receive the effluent from an effluent inlet. A fuel gas or oil nozzle directs a spray of fuel forwardly into the first innermost shell, with primary air also flowing into the first shell to provide initial combustion of the resulting air-fuel mixture. The effluent flowing from the heat exchange passageway flows partly through an annular secondary inlet into the combustion zone of the second intermediate shell, and partly through an annular tertiary passageway into the final combustion zone of the third outermost shell.

Abstract: Apparatus for testing a surface coating on a glass container. In this apparatus, a glass container is chucked in place on a movable carriage. A second glass container is held in a fixed position above and touching the first glass container. A load of a pre-determined magnitude is then applied normal to the second glass container, the load thereby being transmitted to the first glass container. The carriage is moved to cause the two glass containers to translate relative to one another. The force required to move the carriage is transmitted through a load cell which gives an output signal indicative of the force. The surface coatings applied to the glass containers should withstand a normal load of about one hundred pounds before breaking down and allowing the glass containers to scratch one another. If a scratch occurs during the test, the force required to move the carriage will increase and this may be easily seen.
