摘要:
Hydrogen sulfide is removed from a hydrogen rich gas stream using adsorbents having a low loss of carbon dioxide adsorption capacity upon sulfur loading including high purity silica gels, titania or highly cross-linked, non-chemically reactive resins. The adsorbents may be used to adsorb both carbon dioxide and hydrogen sulfide, or may be used as a guard bed upstream of a separate carbon dioxide adsorbent.

The present invention provides a process for making a complex metal oxide comprising the formula AxByOz. The process comprises the steps of: (a) reacting in solution at a temperature of between about 75° C. to about 100° C. at least one water-soluble salt of A, at least one water-soluble salt of B and a stoichiometric amount of a carbonate salt or a bicarbonate salt required to form a mole of a carbonate precipitate represented by the formula AxBy(CO3)n, wherein the reacting is conducted in a substantial absence of carbon dioxide to form the carbonate precipitate and wherein the molar amount of carbonate salt or bicarbonate salt is at least three times the stoichiometric amount of carbonate or bicarbonate salt required to form a mole of the carbonate precipitate; and (b) reacting the carbonate precipitate with an oxygen containing fluid under conditions to form the complex metal oxide.

A server device, and related systems and methods for managing dialysis patient information. The patient information includes information relating to stages of data collection including baseline characteristics, eligibility for treatment modalities, and outcomes. A remote terminal is configured for displaying in the remote terminal a first user interface for receiving the patient information for the subject patient. The server is configured to receive from the remote terminal the patient information for the subject patient and store said patient information in a patient record in the memory, and determine, based on medical logic rules, whether the patient information is consistent with the patient record in order to proceed to a next stage of data collection, and if so permitting displaying in the remote terminal a second user interface for receiving patient information relating to the next stage of data collection.

Complex metal oxide-containing pellets and their use for producing hydrogen. The complex metal oxide-containing pellets are suitable for use in a fixed bed reactor due to sufficient crush strength. The complex metal oxide-containing pellets comprise one or more complex metal oxides and at least one of in-situ formed calcium titanate and calcium aluminate. calcium titanate and calcium aluminate are formed by reaction of suitable precursors in a mixture with one or more complex metal carbonates. The complex metal oxide-containing pellets optionally comprise at least one precious metal.

A mechanism for feeding deer is disclosed. The invention comprises an annular feed trough for holding food; food storage means above the feed trough for replenishing the feed trough by gravity; an electrified standpipe comprising a plurality of legs for vertically elevating the feed trough; and a plurality of electrodes forming an electrode collar with a plurality of radially extending pins to provide an electric shock to game birds which attempt to feed and a switch for activating the electrodes.
摘要:
A crimping system comprises a frame having a plurality of plates with a clamp adjacent to the lower end. Applicator mechanisms are adapted to feed crimpable components coupled together by and releasably coupled to a carrier. A crimping mechanism has an anvil with at least one tooth and a nest with at least one recess associated with the anvil. A feeding mechanism coupled to the frame adapted to feed crimpable components between the anvil and the nest. An actuator arm coupled to the frame is adapted to move the anvil and nest toward each other.
摘要:
A process is disclosed for reversibly absorbing acid gases from gaseous mixtures wherein a salt hydrate is heated to a temperature above its melting point and exposed to an acid gas which is absorbed by the salt hydrate to form a salt hydrate melt. This melt is thereafter cooled to a temperature sufficient to solidify the melt and to desorb the acid gas from the solidified salt hydrate. Preferred salt hydrates include tetramethylammonium fluoride tetrahydrate and tetraethylammonium acetate tetrahydrate.
摘要:
A method and apparatus are provided for welding vinyl window and door frames. The apparatus includes a counting circuit or the like for measuring the time taken for burning off a selected length of a thermoplastic frame member. This time can be used to calculate a sufficient or optimal period for performing a heating or plastification step. Once the ends of the frame members are properly heated (plastified), they are fused by urging them towards each other. The fused members are then cooled for a period of time which also corresponds to the time required for burn-off. The apparatus further includes a heating plate which is pivotable between an operating position and a retracted position. The heating plate is also movable so that different surface portions can be used during burn-off and heating phases.
摘要:
A multi-element clamp is used in association with a frame corner welding apparatus. The clamp or jig consists of a base element, a floating element and a clamp element. The floating element is bias coupled to the base element and when driven to clamp position serves as a clamp, with respect to the base element and is converted to a base element with respect to the clamp element.
