In another form the hand protecting shield is of conical shape having a hole through its narrow end through which a probe can be extended and manipulated by a hand received within the protector. The protector includes laminated layers of aramid fibers together with other tough blast resistant materials such as polycabonate.

Abstract: A system implementable using a programmable processor includes a plurality of pre-stored commands for building an inventory of audio, musical, works or audio/visual works, such as music videos. A plurality of works can be collected together in a list for purposes of establishing a play or a presentation sequence. The list can be visually displayed and edited. A plurality of lists can be stored for subsequent retrieval. A selected list can be retrieved and executed. Upon execution, the works of the list are presented sequentially either audibly or visually. The works can be read locally from a source, such as a CD, or can be obtained, via wireless transmission, from a remote inventory. If desired, establishment of a predetermined credit can be a pre-condition to being able to add items to the list for presentation.

Abstract: The invention relates to detection performed over millimeter and submillimeter wavelengths, especially to imaging solutions functioning over a submillimeter-wavelength range. The system of the invention uses detectors, comprising antenna coupled bolometers together with wavelength selective optics. The detector matrix is preferably curved for reducing the number of imaging errors. In order to provide a curved detector matrix, the detector matrix is constituted by flat submatrices, each being provided with one or more integrated antenna coupled bolometers. The detectable frequency range is preferably limited in two stages, first by means of wavelength selective optics and secondly by means of the operating band of the antenna of an antenna coupled bolometer. In order to focus the incoming radiation on bolometers, the bolometer substrate is fitted or the surface or interior of the bolometer substrate is provided with a bolometer lens or a corresponding optical element in alignment with each bolometer.

The arrangement comprises nozzles that blow air jets towards each other parallel to the opposite walls of the fluidized bed boiler and nozzles in the middle of the walls arranged to blow air toward the center of the fluidized bed boiler.

Abstract: A “push-up” type package for a frozen confection includes a cylindrical tube, and a plunger member slidably positionable within the tube for pushing a frozen confection product from within the tube. The plunger member includes a piston-like pushing portion, and a generally elongated handle portion extending therefrom. The pushing portion of the plunger member includes a surface which defines printing indicia, such as a character, letter, number, etc., which permits the plunger member to be used as an ink stamp after consumption of the frozen confection. The configuration of the plunger member, including an elongated handle, permits it to function naturally as an ink stamp, so that ink can be applied to the printing indicia, and thereafter, inked impressions of the printing indicia applied to suitable paper or other surfaces.

Abstract: An ambient condition detector includes at least a sensor for a first ambient condition and a second, sensor which is responsive to a second ambient condition not necessarily correlated to the first condition. Control circuitry, coupled to both sensors, processes an output from the first sensor to reduce transients and/or noise therein which are not correlated to the first ambient condition. Processing characteristics are altered in response to an output from the second sensor. The processing can take place at the detector or, in part, at the detector and, in part, at a displaced, common control element. The output from the first sensor can also be used to modify the processing of the output of the second sensor.
