An antenna mounting for mobile and portable radios with an antenna element which can be quickly and easily removed, replaced, or secured in selectable positions manually without hand tools. The antenna is received and supported by a manually rotatable setscrew which engages a complementary threaded opening in a selectively positionable arm assembly. The arm assembly is pivotally attached to a fixed vertical support perpendicular to the antenna mounting base. The pivoted arm allows the antenna se...

A pipe hanger in which the height of a suspended pipe can be adjusted comprises a telescoping hanger rod having a first section and a second section which slides within the first section and a means for securing the two sections in a fixed relation to one another. The first section has at least one pair of diametrically opposed holes and the second section has sets of diametrically opposed holes running axially along its length. A pair of manually operable keys is pivotally attached to a ring wh...

A telescoping closet flange for bringing a vertical drain pipe even with the level of a concrete floor comprises a cylindrical body, a seal, a slide and a seal cap held together by fastening members. Prior to pouring the concrete floor, a spacer sleeve is fitted over the drain pipe so that, when removed, sufficient space is left for the telescoping closet flange. After the concrete has set, the spacer sleeve is removed and the telescoping closet flange is placed over the drain pipe. The flange m...

A dual function overcap for a cylindrical container, having a bead about the top edge and generally used for snack foods, includes a substantially planar covering portion and a downwardly extending lip. The dual function overcap fits over the container with a bead by engaging the downwardly extending lip or can fit a shortened form of the same container without a bead, or the same, or similar, container without a bead. In one form of the invention, the overcap must be flipped over to attach the ...

A non-metallic industrial container having a fire resistant outer layer made from a polymer or other thermoplastic resin filled with an intumescent powder and forming part of the structure of the container is provided. The container may be a plastic drum, fibre drum, composite intermediate bulk container or other suitable industrial container. The intumescent layer protects the container from fire by expanding and charring when exposed to intense heat.

An improved device and method for attachment of a plumbing fitting to a pipe or other drain receptacle is described in which the device has at least one elastomeric rib disposed about the outer circumference of the body of the device for forming a watertight seal against the interior wall of the drain receptacle. The ribs are angled in an axial direction opposite to the direction of insertion, allowing easy insertion into a drain receptacle, while causing a radial self-tightening force resisting...

A pulsating shower head that employs a rotor for effecting the discharge of a variable pulsating spray, a variable continuous spray, or a combination of both comprising an upper body housing, a rotatable lower body housing, a stationary stem housing affixed to the upper body housing, an O-ring retainer affixed to the stem housing, and a stem--rotor housing assembly that moves axially when the lower body housing is rotated. An O-ring affixed to the stem acts in conjunction with the O-ring retaine...

A container for packaging and displaying cutlery and the like having a display area for displaying one of the items contained therein. The container allows a consumer to touch and feel the handle of the item on display while preventing easy removal of the item from the container. The container comprises an outer box and an integrated inner tray holder formed from a single blank of flexible material. The outer box comprises a rear panel, top and bottom flaps hingedly connected to the rear panel, ...

A diver's air tank pressure gauge having audible and visual alarms, an alarm pointer for indicating the pressure at which the alarms will activate, and a crank assembly for changing the position of the alarm pointer. The pressure gauge dial has a cutout for limiting the travel of the alarm pointer between acceptable high and low pressure limits. When the air tank pressure equals a preset alarm pressure, an electrical circuit is completed which activates the alarms. The diver can then turn off th...

A reusable concrete spacer sleeve comprises a substantially cylindrical body having a plurality of inwardly extending fins. The sleeve is placed over a vertical drain pipe prior to pouring a concrete floor. After the concrete has set, the sleeve is removed, leaving an annular space around the pipe for accommodating a flange. A lid may be fitted onto the sleeve to prevent debris or other foreign matter from entering the pipe or the annular space around the pipe.
