Abstract: This invention relates to an instrument for the detection of microorganisms in a culture media by means of the measurement of the gaseous products generated during bacterial metabolism, without the need for extracting the products of metabolism from the culture vessel in order to perform the measurement. A special vial containing a gas-liquid separation system permits the measurement through the walls of the vial by determination of the infrared absorption by the gaseous contents within the vessel. While intended primarily for blood-culture testing, the method is applicable to other microbiological and physical chemistry investigations where changes in gas concentrations must be determined in a simple, convenient manner. An alternate embodiment is shown and described whereat a high concentration of gas is present and the infrared energy path is too long for accurate measurement.

This sheath is initially in a compact and secured condition on the needle hub and has a substantial portion of the needle exposed for insertion into a patient or vial. Two embodiments employ a compression spring. Three embodiments avoid a spring per se, but have a corrugated portion and a flange portion that are manipulated by an attendant to urge the sheath forward to enclose the sharpened end of the needle. In all embodiments, the forward end includes a transverse wall in which is formed an aperture that is slightly larger than the shank of the needle. Protection to the exposed needle before use is provided by a conventionally removeable shield which is removed at time of use. After withdrawal of the needle from the patient, the sheath, with the cap or end portion, is moved forward to enclose the sharpened needle.
Abstract: This suction needle device is used to transfer liquids such as cytotoxic drugs from a stoppered container to a syringe. This device has a sharpened needle which is conventionally attached to a hub. A thin-walled tubular sleeve is mounted on the shank of this needle and is disposed in a telescope fashion around this shank. One end of the sleeve is disposed a short distance from the sharpened end of the needle so that the stopper may be entered by the sharpened needle and sleeve and provides a seal when so penetrated. A crimping tool provides opposed and longitudinally displaced localized crimps to deform the sleeve to the extent that a positive engagement with the shank of the needle is made. The crimps are limited enough to provide positive securing of the sleeve without bending or distorting the interior capacity of the needle to draw fluids into the syringe. The thin-walled sleeve may have an aperture in the side and in flow communication with the air passage between the needle shank and sleeve.

Abstract: This invention pertains to a troughing conveyor for products such as bags, boxes, cartons and the like. It is anticipated that products of like configuration and initial orientation are carried to an orienting conveyor means. This conveyor system has a stop plate that is actuated as and when required to insure that an oriented product has exited the system before entrance of another product to said system. Two plate-like conveyors are arrayed in tandem and are of like size and extent. These conveyors are troughed to provide a shallow included angle and the upper extents are also formed with convex arc so that the product is transported on two points. Each of these conveyors is independently driven by variable-speed gear motors, each with computer programs controlling the speed of each of the conveyor extents. An electric-eye counter device insures that an oriented product has exited the system before another product has been delivered.
Abstract: The disposable breast pad of this invention is generally circular and there is formed therein a predetermined angle of score lines providing fold assists. The barrier sheet of thin, pliable plastic material is an impervious barrier to the passage therethrough of excess fluid from the breast. The disposable pad is folded at radial edge portions to provide a manipulated overlay and form a conically-shaped cup. The outer surface of the barrier sheet has an applied adhesive which not only retains the overlap edge portions, but also when exposed provides a non-toxic contact-adhesive providing retention of the pad in the brassiere cup until the pad is to be removed and discarded. The barrier sheet is not cut radially; therefore, unwanted leakage therethrough cannot occur. Folding of a portion of the pad produces three or five thicknesses at the overlap.
Abstract: This invention is an improved concept of the clamp shown in U.S. Pat. No. 3,736,629, as issued June 5, 1973. This construction of a clampingdevice includes forming two C-shaped arms, each of which is an assembly of two plate-like members of sheet metal. These two arm assemblies are pivotally retained at one end with the plate-like members in an overlay condition. A pivot pin has an enlarged center portion which acts as a spacer and has two eccentric cam areas sized and spaced to actuate apertures formed in one of the arm pairs. Shouldered rivets retain these arm assemblies in spaced array and a stop pin secured in this pivot pin has a length sufficient to engage a secured rivet. At one limit of movement of the stop pin, the cam areas move one arm assembly to a maximum clamping force and, at the other limit of movement of the stop pin, the cam areas are in a reduced-force application.
