Abstract: A modular shell system of a hard insulation material fabricated in a geometric shape that encapsulates a pipe in insulation is provided. In an attic installation for example, the entire insulation component is inserted over a pipe and into the space between the building structural wood framing members resting on the interior sheathing below. By placing a series of these interlocking insulating modules along a pipe that is run perpendicular to the building construction members, the piping is encapsulated in a continuous insulating system along its entire length. This design facilitates natural heat flow into the pipe with an open pipe slot cavity in the insulating module that allows natural convection heat to pass up through the elongated piping slot, allowing it to come into contact with this piping.

Abstract: Connectors and cable assemblies having a label stored in a label storage area of a component of the connector along with methods for making the same are disclosed. The label is extendable from the label storage area with a label length that is longer than a length of the label storage area, thereby providing the craft with adequate space for marking information. Suitable components of the connector for the label storage area include housings, boots, clips and the like. Further, the label storage area protects the label from damage while also maintaining a relatively small footprint for the connector.

Abstract: A method of cleaving an optical fiber using a disposable abrasive film is disclosed. The method includes preparing an end of an optical fiber by exposing a length of the optical fiber. The exposed optical fiber is brought into contact with a tangential swipe formed of abrasive film to cause the optical fiber to cleave substantially at the location of contact leaving an optical fiber stub with a cleaved end. The optical fiber stub is polished with a polishing film having a coarse grit and may be polished a second time with a polishing film having a fine grit.

Abstract: A communications circuit includes a filter module with a sampling window, a control module, and an input buffer. The control module has a ray parameter interface to obtain information regarding significant ray changes that make it desirable to re-position the sampling window. The control module determines re-positioning parameters, responsive to this information, which reflect the re-positioning of the sampling window. The input buffer obtains samples of a received signal and outputs received signal data to the filter module. The filter module obtains the re-positioning parameters from the control module, and the filter module and control module temporally re-position the sampling window in duration and/or location in accordance with the re-positioning parameters, and output a filtered chip.

Abstract: An air dryer cartridge assembly, used in a compressed air system, includes a rigid porous layer, a fibrous material layer, a diffusing layer and a desiccant for filtering and drying compressed air passing in a first direction during a charging cycle. The compressed air passes through diffusing layer, the fibrous material layer and the rigid porous layer in a second direction during a purging cycle. The desiccant, which is downstream of the rigid porous layer, the fibrous material layer and the diffusing layer during the charging cycle, reduces moisture in the compressed air during the charging cycle. The use of diffusing layer downstream of the fibrous material layer during a charging cycle disperses the compressed air so that moisture removal is improved in the desiccant.

Abstract: An adhesive applicator is disclosed for the application of a hot melt adhesive to the spine of a book block so as to adhesively bind the book block to its respective cover so as to form a perfect bound book. The applicator has a heated head in which a small quantity of a hot melt adhesive sufficient to bind at least one book block to its cover is quickly heated to a temperature such that it may be applied to the spine. The head is brought into operative engagement with the spine and is moved with respect to the spine so that the melted adhesive forced (dispensed) out of the head onto the spine. This applicator is particularly well suited for use with print on demand book printing and binding apparatus. A method of applying the adhesive to the spine of a book block is also disclosed.

Abstract: A clip, configured to support a furcation body, includes a keyhole member, a catch, a cover, and an arm. The keyhole member may be received in a keyhole of a mounting surface, and is offset from a bottom of the clip via a slot guide such that when the bottom of the clip slides along the mounting surface, a top of the keyhole member engages an underside of the mounting surface to lock the clip to the mounting surface. The catch extends from the bottom of the clip in a direction that the keyhole member is offset from the bottom of the clip. The cover is coupled to a wall of the clip extending from the bottom of the clip in a direction away from the catch. The arm extends from the clip in a direction away from the catch and provides a handling point above the clip.

Abstract: A dual-motion collar device is described, which elicits an additional motion from an operator when initiating a parking brake release in a vehicle. The collar device comprises top and bottom collars with a compressed and torsionally stressed spring there between, such that the collar device maintains a park brake plunger knob in a locked state. An operator twists the top collar to align interlocking features on the top and bottom collars, and then pushes downward to unlock the collar device. The operator then pushes downward on a park brake plunger knob around which the collar device is installed to actuate a parking brake valve assembly and release the parking brake.
