A wiping device may be a friable layer or an absorbent pad made of a material that can absorb and retain a fluid composition and can be attached or is attached to an item of clothing, such as a sock, shoe, compression sleeve, etc. The device is impregnated with an adhesive-type tacky substance that is released when a shoe sole is wiped against it to clean the shoe sole and allow surface dust and debris to be removed from the shoe sole. The deposited substance also forms a film or coating that remains adhered to the surface of the shoe sole to improve traction by imparting tackiness to the shoe sole.

An athletic shoe coating for traction enhancement includes a pressure sensitive adhesive (PSA) and a tackyfying resin and a film former initially in solution within a solvent suitable for application to the surface of a shoe sole in liquid form, such as by spraying, rolling and brushing the solution onto the shoe sole. After the solvent evaporates a film or coating attaches or is bonded to the shoe sole that exhibits the property of dynamically modifying the traction properties of the shoe sole when pressure and shear forces are applied to the coating. Such modification causes the exterior surface of the film or coating to “refresh” the exposed surface upon impact. This imparts continued tackiness over extended use. Impact modifiers may be added for controlled release of a solvent to temporarily dissolve or soften the film or coating to promote such refreshment of the coating outer surface.

Provided are glass compositions with higher softening point temperatures than conventional glasses, which improve flame penetration test performance of flexible duct insulation. In particular, the glass compositions have a softening point in the range of about 1230-1276° F., a log-3 viscosity temperature in the range of about 1802-1879° F., and a temperature difference between log-3 viscosity and liquidus temperatures of at least 150° F. These glasses are specially formulated to increase softening point while only minimally increasing log-3 viscosity temperature, so as to allow fiber insulation manufacturing without requiring increased energy use.

An example sifter shovel assembly includes a handle and a scoop secured to the handle. The scoop includes an outer edge portion. An apertured area of the scoop has a plurality of apertures extending through the scoop and an unapertured area of the scoop extends from the outer edge to the apertured area. An example method of assembling a sifter shovel includes creating a plurality of apertures in a sheet of material and forming the sheet of material into a general scoop shape. The example method then secures a handle to an unapertured area of the sheet of material.

A system to prevent unauthorized access to a protected device includes a test access port operable to mate with a test access connector, a security key port operable to mate with a security key and a security device in electrical communication with the test access port and the security key port. The protected device is in electrical communication with the test access port when the security device is enabled based on the security key. The test equipment is authorized for access to the protected device when the security device is enabled.
摘要:
A passive optical anti-tamper system including one or more light pipes, one or more light detectors and an alarm. The light pipes each include an input end and an output end and are located within a chassis with the one or more light detectors. The one or more light detectors are optically coupled to the output ends of the one or more light pipes. The alarm is operable to transmit a tamper-event-warning signal if an increased light level is detected by at least one detector.
