Abstract: An improved apparatus for reducing the drag of a moving body at the trailing end thereof by positioning panels extendable rearwardly from the trailing end of the moving body to minimize drag wherein deployment of the rearwardly extending panels is facilitated such as by allowing for automatic deployment of an upper horizontal panel responsive to conventional deployment of one or more vertically extending panels at forming the upper panel in a frame construction covered by flexible material. The upper panel can be spring loaded to further facilitate deployment and the lower horizontal panel can be easily deployed and possibly stored with respect to one of the vertically extending panels. Use of the frame configuration for deploying the upper horizontal panel also facilitates movement from the deployed to the stored position such as by including release cords preferably secured at one end with respect to the vertically movable preferably trapezoidally shaped frame.

Abstract: A refrigerated display case with an improved air flow control system located in the lower portion thereof along with an improved means for controlling spillages and other contaminants which commonly fall downwardly into the tank or lower area thereof. The spillage controls including a waste control outlet along with an inclined coil cover and fan housing as well as a deck plate extending thereover. The deck plate also defining the plenum chamber within which the inclined fan housing and inclined coil and coil cover are located. A front bracket is included which allows attachment of a return grill thereto along with a support shelf for holding the refrigeration line means away from the waste receiving outlet.

Abstract: An improved design for a refrigerated display case which significantly enhances airflow characteristics by including a gradual radius within the transition sections in areas where the refrigerated airflow path must change directions to greatly facilitate smooth flow of refrigerated air therethrough. Also disclosed is an improved construction for providing insulation for a refrigerated display case including an inner and outer panel spaced apart to define an insulation holding chamber therebetween and including thermal breakers at the ends thereof for maintaining the panels in spaced relation to each other and for closing off the end section thereof to retain insulation therein. The inner insulation panel defines the outer boundary of the airflow path.

Abstract: A collapsible wheel chock apparatus having a main body member with a preferably concave wheel engaging surface and a swing arm member pivotally secured to the main body member which includes a locking slot located therein with preferably a locking tab extending into the slot. A cross bar member is pivotally secured to the main body member and is movably secured and retained within the slot defined in the swing arm member. The cross bar member is adapted to be locked adjacent one end of the locking slot by a spring bias locking mechanism to facilitate holding of the wheel chock in the raised position for abutment against a vehicle wheel. The cross bar member is movable to the opposite end of the locking slot to allow the swing arm member and cross bar member both to be collapsed against the main body member for storage in this collapsed position.

Abstract: A solid state machine controller for actuating a machine. The machine controller requires near simultaneous interruption of two photo-optic beams by fingers from both operator hands to actuate the machine. The beams are part of switches located at opposite ends of a tubular enclosure. The photo-optic beams are located in annular openings surrounded by embossed rings to prevent beam generator and receiver soiling as well as accidental machine actuation.

Abstract: An apparatus usable for controlling the removal of newborn infants from a maternity ward or other restricted area which includes an electrical transponder member detachably securable to an umbilical cord clamping device such that the transponder is attached to the umbilical cord clamping device when clamped upon the umbilical cord of a newborn infant. The transponder members are positioned within a housing and include a stud extending outwardly therefrom which is adapted to extend through a securement opening defined by the umbilical cord clamping device. When the umbilical cord clamping device is closed the securement opening closes somewhat and thereby attaches the transponder unit with respect to the umbilical cord of the infant. When the infant is discharged from the maternity ward the transponder units can be recycled by removal thereof simultaneously with the umbilical cord clamp.

Abstract: A configuration for a pillowcase for use in covering of a conventional bed sleeping pillow wherein the pillowcase includes an upper planar member having two lateral edges and two longitudinal edges and a lower planar member also have two lateral and two longitudinal edges. The two planar members are integrally formed along the bottom edge therebetween and are attached along the side edges. The two remaining longitudinal edges define an access opening for allowing placement and removal of a pillow extending therethrough. This design further includes a closing flap integrally formed with respect to the longitudinal edge of the upper planar member and includes a hook and loop fastening means thereon detachably securable with a mated hook and loop fastening device positioned on the lower planar member such that the flap extends across the pillow access opening for retaining of the pillow firmly therein.

Abstract: A raft apparatus having inflation flotation structures which are capable of heat sealing for assembly thereof wherein one or more flexible buffer members of not heat sealable material are adapted to shield portions of the panel members of the flotation raft from heat sealing to surrounding areas to thereby form an effect seal particularly by allowing heat sealing operations to be formed upon already assembled sections. At least one of the two panel members will be inflatable and will include a buffer member positioned therein to shield the heat sealing point thereof from the remaining portion of the inflatable structure member to prevent undesired heat sealing thereof during heat sealing of the interconnection between the two main panel members.

Abstract: An inking roller which includes a plurality of ribs on the exterior thereof and a plurality of recesses for holding ink in between the individual ribs. The inking roller is adapted to be rotated upon contact with a conventional ink fountain and is selectively capable of being locked to prevent rotation thereof at certain times when in contact with the engraving die. The inking roller is adapted to apply engraving ink to the engraving die in the engraving areas thereof and is adapted to wipe the non-engraving areas of the engraving die with the external ribbing on the exterior surface of the cylindrical inking roller.

Abstract: An apparatus adapted to be secured to an emergency vehicle such as a fire truck which is adapted to store a collapsible water storage tank and to be moved upwardly to the stored position with the stored tank in the inverted position to facilitate drainage therefrom. The apparatus includes a main bracket secured to the vehicle with a back arm pivotally secured to the main bracket and extending upwardly therefrom and a lower arm pivotally secured to the main bracket and extending outwardly therefrom. A shelf arm is pivotally secured to the distal ends of the lower arm and the back arm to facilitate control and movement thereof. Pivotal connection between the back arm and the shelf arm is made through an actuator drive pin. The actuator drive pin is also pivotally secured with respect to an axially extensible actuator such as an electrically powered piston adapted to facilitate movement of the article retaining apparatus between the stored and lowered positions.
