Abstract: A fluid filter for preventing the introduction of fluid contaminants into an associated device is disclosed. The filter has a housing having an inlet chamber and an outlet chamber. The inlet chamber forms an inlet port of the fluid filter and the outlet chamber forms an outlet port of the fluid filter. A number of serially connected intermediate chambers are coupled between the inlet chamber and the outlet chamber. Each of the chambers contains an absorbent material for capturing the fluid contaminants and generally preventing their introduction into the associated device.

Abstract: A bar code identification stencil for uniquely identifying a plurality of articles. The stencil includes a carrier strip, which carries an identification code or symbology. The identification code or symbology is formed of a plurality of spaced apart data cells, or data cells, which are used to form a machine readable bar code. The stencil will be made of materials compatible to the manufacturing processes, which make the articles to be marked, and compatible to the materials out of which the articles to be marked are made. The stencil is scalable in size and shape, as are the data cells, or data cells, scalable in size and shape—all as required by the specifications of the data symbology to be directly marked on the part, or article. The bar code is unique for each of the plurality of articles to be identified.

Abstract: A masking tape used in spray application or removal of coatings along a demarcation line. The tape is engineered so that during the spraying process the coating being applied or the abrasive grit being used to remove a coating makes substantially no contact with the lateral edge of the tape along a shadow zone flanking the demarcation line. The shadow zone is formed between the demarcation line and the tape in line of sight with the coating or grit being sprayed. In a preferred embodiment for use in spray painting vehicles on a production basis, the body of the tape is rubber with a release coating applied to its top surface formed of polyethylene film.

Abstract: A scalpel blade extractor and disposal unit formed of semi-flexible plastic material. The unit has a substantially closed chamber within which a blade mounted on a handle is received. The chamber has a top and a bottom and an abutment shoulder is attached to the top and extends below the plane of the bottom for the purpose of retaining the blade in the chamber. A mechanism is provided for increasing the distance between the top and the bottom so that the blade on the handle passes under the abutment shoulder. The bottom has a groove and shoulders around the groove for prying the heel of the blade up such that it is stopped by the abutment shoulder when the handle is withdrawn leaving the blade behind in the chamber.

Abstract: A lightweight protective headgear having ventilating qualities and having an outer shell, an elastomeric liner with a plurality of elastomeric members arranged with airspace therebetween and a porous material to keep the wearer's hair from filling the airspace between said elastomeric members. The elastomeric members have a base and a surface tapering towards a truncated apex and are arranged in a loosely fitted side by side pattern with their small ends directed axially inward for engaging the head of a wearer and with their large ends engaging the inside of the outer shell. The elastomeric members vary in height to conform the liner to the wearer's head and are arranged along the inside of the outer shell in front to back rows having greater spacing between the rows than between the elastomeric members in the rows.
