Abstract: A security device includes a securement washer having a securement washer hole, and a circumferential groove within the hole. An end cap includes a well that contains the securement washer, and an end cap circumferential wall that extends around the securement washer. A portion of the end cap circumferential wall extends over a circumferential portion of the securement washer located around the securement washer hole. The portion of the end cap circumferential wall comprises tamper-evident indicia on a surface thereof. The tamper-evident indicia is formed so as to remain unchanged until and unless the security device is tampered with. The security device may be manufactured by forming tamper-evident indicia such as a disturbance on a surface of an end cap such that the indicia remains unchanged until or unless the security device is tampered with. The tamper-evident indicia may be formed by an orbital forming process.

Abstract: A label and a label for a security seal are described. The label includes a flexible body with first and second portions connected to one another via a separable connection. A first adhesive is disposed on a rear surface of the first portion. A second adhesive is disposed on a rear surface of the second portion. First information is applied to the first portion. Second information is applied to the second portion. At least a portion of the first information is identical to a portion of the second information. Either the first portion or the second portion includes tamper-evident indicia such that attempted separation of either portion from a substrate, once affixed, exposes the tamper-evident indicia. The first adhesive is formulated to securely affix the first portion to a seal body. The second adhesive is formulated to securely affix the second portion to a document.

Abstract: An umbilical connection for use in a hazardous environment like a floating roof storage tank has one or more hydraulic hoses, one or more electrical cables or a combination thereof. Each hydraulic hose has a static dissipative and abrasion resistant covering. Each electrical cable has an abrasion resistant coating. The hoses and cables are bundled and wrapped in a static dissipative and abrasion resistant open mesh sheath or an overbraid to form the intrinsically safe umbilical connection.

Abstract: A hatch cover for deployment over a hatchway formed in a floating roof liquid storage tank permits rapid loading and unloading of inspection or maintenance equipment and minimizes vapor emissions from the tank. The portable hatch cover has two base plates movably connected at a hinge and each defining complementary recesses. A circular flange extends from the bottom surfaces of the base plates to seat the hatch cover in the hatchway. Two door panels are movably connected at hinges to the top surfaces of the base plates. When one or both of the door panels are opened, equipment may be loaded into the tank through the complementary recesses. When closed, the door panels cover the recesses in the base plates. Complementary notches in the door panels provide an opening through which equipment tubing or wiring may extend when the door panels are closed. A collar gasket optionally may be wrapped around the tubing or wiring as a further means to limit vapor emissions from the tank.

Abstract: A self-grounding soldering tip having a spring which serves for connecting the soldering tip to a heater bobbin for establishing a secure grounding of the soldering tip. A bobbin tube extends within the heater bobbin for removably retaining the soldering tip within the bobbin. The connection between the spring and bobbin tube provide tip-to-ground continuity. Moreover, the contact surfaces of the spring and bobbin tube are wiped clean upon plug-in and plug-out. The spring and bobbin tube are located in a cooler area of the soldering iron to slow down the rate of oxidation. Also, the spring and bobbin tube are made of the same or compatible materials, e.g., stainless steel, to prevent reactions that normally occur between incompatible metals.

Abstract: An automated car park (10) is illustrated having a plurality of storage locations (21) arranged on a plurality of levels (42) and transportation means (53) for transporting the cars to or from selected storage locations (21). The transportation means (53) includes a pallet truck (57) which travels along guide rails (32) positioned on either side of an aisle (44) separating opposing rows of storage locations. A pallet dolly (56) supports a pallet (55) upon which a car (54) may be supported and enables a selected pallet to be transferred between storage locations (21) and the pallet truck (57). Lifting means are provided to lift the pallet truck between levels.

Abstract: An actuator for use with electric conductor systems using push-to-connect fittings, especially suitable for tractor/semi-trailer connections employing an actuator body having linearly displaceable plungers mounted upon a flexible conductor fitting which separates the conductor fitting and receptacle upon the plungers extending. A lever operator mounted upon the actuator body is connected to a flexible lanyard of a length less than that of the electrical conductor whereby tensioning of the lanyard occurs before damaging tension can be applied to the conductor and lanyard tensioning extends the plungers to disconnect the conductor fitting and receptacle.

Abstract: A conduit fitting for use in conduit systems having attachment structure at each end which is galvanically isolated from each other to prevent galvanic corrosion and deterioration. The fitting components are assembled to constitute a unit to facilitate handling and inventory.
