A cooking apparatus for preparing food includes a vessel, a burner, an electrically controllable valve, a thermocouple and a thermally actuated switch. The vessel is configured for containing a fluid and the burner is positioned for providing a gas flame to the vessel. The valve is coupled between the burner and a gas source and the thermocouple is positioned to sense a temperature of the flame provided by the burner. The thermally actuated switch is serially coupled between the valve and the thermocouple. The switch provides a conduction path between the valve and the thermocouple, when a temperature sensed by the thermal switch is less than a predetermined temperature. The switch is integrally mounted to the vessel to sense a temperature of the fluid contained within the vessel.

A fire safety fluid flow device for engagement with a Schrader valve including a sliding valve a housing having a fluid path therethrough and a pressing member. The pressing member presses against the sliding valve of the Schrader valve when engaged therewith to allow fluid flow through the Schrader valve. The pressing member continues to maintain the sliding valve in an open position when the device is below a predetermined temperature and connected to the Schrader valve. The pressing member is configured to no longer press against the sliding valve of the Schrader valve at and above the predetermined temperature to allow the sliding valve of the Schrader valve to thereby stop fluid flow through the Schrader valve.

In some embodiments, techniques include identifying a plurality of tasks associated with an identifier corresponding to an electronic device. A task series is generated so as to include the plurality of tasks, where each task in the series is associated with a performance time. When it is determined that the task has not been completed by the performance time, the task series is updated.

There is disclosed a system and method for applying an amorphous NiP alloy coating on pipes and rods, particularly for use in the oil and gas industries to inhibit corrosion, In an embodiment, the method comprises applying an amorphous nickel phosphorus or NiP alloy coating to pipes and rods for use in oil and gas industries, comprising; preparing a Watt's type nickel phosphorus (NiP) plating bath solution utilizing a Watt's type nickel electrolyte containing hypophosphorous acid; maintaining the plating bath solution temperature at between 120° F. and 170° F. adjusted to regulate phosphorus content over 11%; regulating a pH level of the plating bath solution between 1.0 and 3.0 utilizing sulphuric acid; and controlling the cathode current density in the range of 10-100 amps/sq/ft. Significant cost savings may be realized by using an electroplated nickel-phosphorus alloy over regular carbon steel alloy components at sufficient thickness to be pore free replacing the use of more expensive components made of stainless steels or nickel base alloys.

A photometric device for investigating a sample, comprises an array of radiation sources that are spaced apart from one another, and which are operable to generate radiation that differs from that generated by the other radiation sources in the array. The device includes a lens arrangement for focusing the radiation at a region of space where a sample may be located for example by means of a sample holder, and at least one detector for receiving radiation from the region of space. Preferably, a number of detectors are employed that are spaced apart from one another, and especially about an axis of the device, so that one radiation detector can detect radiation transmitted by the sample and the other detectors can detect radiation scattered by it. The radiation sources may be time division multiplexed so that in each time slot the detectors receive radiation originating from each radiation source. In an alternative embodiment, the radiation from the region of space may be transmitted to the sample via a beam homogeniser, for example an optical waveguide in the form of an optical fibre, which may be used to reduce or remove speckle where laser diodes are employed as the radiation sources. The device may be used to determine the particle size distribution of particles in a sample by a method employing Bayesian inference.

A security feature for an identification document and method for making it provide layers of security, including, for example, tamper evidence, optically variable effects, and personalized information that links the security information to the document and its bearer. The feature is made by printing a first material representing first information on a core layer of the document. This first material at least partially overlaps the core layer. One example is Xerographic printing of information about the ID document applicant and the applicant's photo. The process also applies a second material representing second information adjacent to the first material. One example is ink jet printing of personal information with a UV curable ink in the form of a relief pattern on the core layer. Finally, the process applies a laminate layer over the core layer. The laminate layer covers the first and second materials. The first and second materials adhere differently to the laminate and core layers such that removal of the laminate layer from the core layer causes a separation of the first and second materials. The relief pattern is made to give the document a tactile feel as well as create optically variable effects.
摘要:
A color laser engraving method engraves a document including a surface layer and one or more sub-layers. The sub-layer includes different colors and orientations of ink. A laser provides openings in the surface layer—to expose color ink in the sub-layer—to create color images and/or text. The different orientations of the colored inks include, e.g., circular, linear and overlapped groupings of ink. A sub-layer preferably includes many repeated instances of the grouping. A digital watermark is embedded in a document via transfer of the digital watermark in an embedded image or text, or by pre-embedding the document via altering intensity of colored inks on the original document card stock. A digital watermark can be carried via modulation with a pseudo-random noise sequence.
