Abstract: An apparatus, including a monitor system including a microphone, first power supply; and transmitter which transmits a first sound indicative of a normal flow of a fluid into a tank and a second sound indicative of a need to cease the flow of the fluid; an attachment device, wherein the monitor system or microphone is attached to the attachment device, and the attachment device is attached to, or attached to an object in a vicinity of, a ventilation pipe; and a receiver system which is headset, earpiece, wearable device, or handheld device, which includes a housing; receiver which receives the first sound or second sound; second power supply; and speaker. The speaker outputs the first audio output indicative of the normal flow of the fluid into the tank and outputs the second audible sound indicative of the need to cease the flow of the fluid.

Abstract: An apparatus, including a monitor system which includes a microphone, a first power supply, and a transmitter which transmits a first audible sound, indicative of a normal flow of fluid into a tank, or transmits a second audible sound, indicative of a need to cease a flow of the fluid into the tank; an attachment device to which the monitor system or the microphone is attached and which is attached to a ventilation pipe or an object in a vicinity of the ventilation pipe; and a receiver system which includes a receiver, which receives the first audible sound or the second audible sound, a second power supply, and a speaker which provides a first audio output, indicative of the first audible sound, or a second audio output indicative of the second audible sound. The speaker outputs the first audio output or outputs the second audio output.

Abstract: An apparatus, including a main housing; an alarm/whistle, wherein the alarm/whistle is mounted or attached to or within the main housing at a top portion of the alarm/whistle, and further wherein the alarm/whistle has a lower portion of the alarm/whistle that extends downwardly and in a direction opposite from the main housing and terminates in a lowermost end portion of the alarm/whistle; and a protective cover, wherein the protective cover is attached to or mounted to the main housing at a top portion of the protective cover, and further wherein the protective cover extends downwardly and in a direction towards the lowermost end portion of the alarm/whistle, and further wherein the protective cover has a lowermost end portion of the protective cover that extends beyond and below the lowermost end portion of the alarm/whistle.

Abstract: A method of manufacturing an object. A thermoplastic matrix material is melted to transform it into liquid matrix material. The liquid matrix material is fed into a chamber via one or more matrix inlets. A fibre is also fed into the chamber via a fibre inlet. The fibre in the chamber is contacted by the liquid matrix material. A coated fibre is extruded from an extrusion outlet of the chamber onto a substrate, the coated fibre comprising the fibre with a coating of the liquid matrix material, the substrate comprising a previously extruded coated fibre. The fibre moves in and out of the chamber at the same velocity relative to the chamber. The coating fuses with the previously extruded coated fibre and solidifies after it has fused with the previously extruded coated fibre. Relative movement is generated between the extrusion outlet and the substrate as the coated fibre is extruded from the extrusion outlet.

Abstract: An apparatus for monitoring a parameter of a solvent during a drying process is described. The apparatus includes a light source providing at least one light beam and a detection system receiving a signal corresponding to the at least one light beam transmitted through a vapor of the solvent flowing through a diagnostic region. A processor can determine from the signal at least one solvent parameter associated with the vapor of the solvent, and the processor can determine from the at least one solvent parameter the instantaneous mass flux of the vapor of the solvent.

Abstract: A multi-spouted serving pitcher construction is disclosed for facilitating spill-resistant retention and delivery of potable liquid. The disclosed open top pitcher includes an angled spill guard which retains splashing or sloshing liquid against spilling. The pitcher also includes at least one auxiliary spout defined in the spill guard. These and other features provide a multi-spouted open top serving pitcher particularly desirable for holding and serving potable liquid in a spill-resistant sanitary manner.

Abstract: Metal plates of tungsten or molybdenum, having an optimum thickness of 1000 micrometers or less, are bonded to respective cathode and anode electrical coatings on the opposed major surfaces of a semiconductor wafer. The metal plates in turn are conductively bonded to the heat pipe walls which are used as the electrical connectors between the anode and cathode coatings and the external working circuit. Heat that is developed by the surge current flowing through the wafer during the first 6 milliseconds, is dissipated into the plates that are bonded to the opposed major surfaces of the wafer, before the cooling capability of the heat pipes is effective. This provides a greater surge current capability for the semiconductor wafer.

Abstract: A semiconductor wafer is sandwiched between the ends of two heat pipes. One end of each heat pipe is in electrical and thermal contact with the wafer. The heat pipes are fastened together so that the wafer is held in compression between the two heat pipes. The ends of the heat pipe, are reinforced from within the heat pipe so that the ends will not buckle due to the compression loading of the wafer.

Abstract: A cooling chamber is bonded to an electrical device to be cooled. The chamber includes a metal wall connecting the device into the working electrical circuit. A thinned portion of the metal wall forms a fuse which will burn out due to an excessive flow of current through the electrical device upon failure.
