摘要:
Reddish-brown to yellow shade colorants suitable for ribbon and ball point inks are produced from the glassy waste by-product of pararosaniline manufacture.
摘要:
A single to dual indexing carton transfer mechanism involving a turret and conveyor, wherein the turret includes equally spaced mandrels which index at a first predetermined rate, and wherein the conveyor indexes at one-half the rate of the mandrels. Partially formed paperboard cartons are stripped from the respective mandrels as the latter index to their 6:00 o'clock position, and set on a stationary rail. A pusher mechanism is cammed to alternately transfer odd numbered cartons to the conveyor during the latter's dwell period, and even numbered cartons to the conveyor while it is indexing, thereby increasing the production rate along a single conveyor line.
摘要:
This disclosure is concerned with thin gas diffusion electrodes comprising an open pore carbon cloth substrate provided with a uniform mixture of catalytic carbon particles and preferably Teflon particles adhered within the cloth poes and to the yarns of the cloth; processes for making and using the same; and assemblies comprising said electrodes and closely spaced preferably noble metal current collecting contacts for use in electrochemical cells operating at high current densities.
摘要:
An inverted conversion press for producing easy-open metal container ends is provided, which combines the functions of end and tab presses. The press includes a tab forming station and an end forming station, disposed one beneath the other and rendered alternately operative by a vertically-reciprocable slide assembly. A method for producing an article, comprised of assembled workpieces, is also provided.
摘要:
A perfusion apparatus including a perfusion circuit that perfuses an organ or tissue has a compartment that supports an organ or tissue during perfusion, an internal cover, and an external cover that closes the apparatus. A wall portion may extend substantially perpendicularly between the internal cover and the external cover to define a document compartment between the internal cover, the external cover and the wall portion. A tamper evident seal will not permit the external cover to open without creating a record of whether the external cover has been opened after the tamper evident seal has been activated.
摘要:
A temperature sensor for monitoring an organ or tissue is configured to measure a temperature inside of a container configured to contain the organ or tissue. The temperature sensor is disposed exterior to the organ container and the temperature sensor is a non-contact temperature sensor. The temperature sensor may be part of an apparatus for perfusing, transporting, and/or storing an organ or tissue. A coolant container may have an aperture through which the temperature sensor measures a temperature of at least one of the organ or tissue or a perfusate fluid surrounding the organ or tissue. The temperature sensor is preferably an infrared temperature sensor. Multiple temperature sensors may be provided that measure the temperature organ or tissue or perfusate fluid surrounding the organ or tissue, for example in case one of the temperature sensors fails.
摘要:
An electric vehicle battery heater includes a housing having a coolant inlet and a coolant outlet. A heating element is positioned within the housing in a heat transfer relationship with coolant for transferring heat to an electric vehicle battery. A thermistor is positioned in the housing to output a signal indicative of a temperature of the battery coolant. A controller energizes the heating element when the signal represents that the coolant temperature is less than a predetermined lower limit.
摘要:
The invention relates to a sulphide catalyst for electrochemical reduction of oxygen particularly stable in chemically aggressive environments such as chlorinated hydrochloric acid. The catalyst of the invention comprises a noble metal sulphide single crystalline phase supported on a conductive carbon essentially free of zerovalent metal and of metal oxide phases, obtainable by reduction of metal precursor salts and thio-precursors with a borohydride or other strong reducing agent.
摘要:
A method for forming a patterned noble metal coating on a gas diffusion medium substantially free of ionomeric components comprising subjecting an electrically conductive web with a patterned mask overlaid thereto to a first ion beam having an energy not higher than 500 eV, and to a second beam having an energy of at least 500 eV, containing the ions of at least one noble metal and a gas diffusion electrode.
