Abstract: ABSTRACT            Cobalt is recovered by treating aqueous solutions con-taining ammonia and cobalt ions with a sufficient amount of an acid in the presence of a catalyst to convert the co-balt ions to a cobalt hexammine ion which is precipitated and separated from the resulting solution.  According to another aspect of the invention, a cobalt compound is pre-cipitated from an aqueous solution of cobaltic hexammine halide by treating the solution with a metallic hydroxide and the precipitate is subsequently reduced to form fine cobalt powder.     21,987

Abstract: ABSTRACT            Surface water, potato pieces and starch particles are remov-ed from raw potato slices as they are transferred from a water bath to a cooker on a perforate conveyor belt.  Streams of air against the topside of the belt place the slices in turbulent motion and air suction through a grid on the bot-tom side of the belt extracts water and starch particles in-to a suction stream from which the particles are separated.

Abstract: RMR1??079 TITLE                 EVACUATION MANIFOLD FOR MEDICAL ANESTHESIA CIRCUITS                        ABSTRACT A manifold is described for use with anesthesia breath-ing circuits and which is adapted to receive exhaust anesthetic gases from the anesthesia breathing circuit for disposal there-of.  The manifold is connectible to a vacuum system for such disposal and includes a needle valve which may be set to estab-lish a desired flow of exhaust anesthetic gas to the vacuum system.  Because the pressures (either positive or negative) within the manifold will also have an effect on pressures with-in the anesthesia breathing circuit from which the exhaust anes-thetic gas is received, it is necessary to control the pressure inside the manifold within certain predetermined limits.  Relief valves are thus provided and which relieve the pressure within the manifold at certain predetermined positive and negative limits.  The relief valves are so arranged that both may be opened manually by a common member which is accessible exterior of the manifold and can readily be displaced by personnel.  The displacement simultaneously opens both valves to free the same from sticking.

Abstract: FOOD SERVING SYSTEM Abstract of the Disclosure An energy saving food serving system for rethermalization of the food and for delivery prepared meals to locations remote from the place of preparation, such as to patients in hospitals and nursing homes.   The system includes a mobile cart having its own rechargeable power pack that is utilized to propel the cart.  This power pack may also be used for heating purposes but, preferably  to conserve battery usage heating may also be provided via a conventional AC source. The cart has separate bays, each having a tier of racks for carrying individual food serving trays.  Each tray has one or more thermally isolated heat transfer devices which are select-ably energized when the tray is in place on a rack in the cart. The trays are constructed to carry conventionally styled removable dishes, bowls, cups,  etc.,  that may be either dispos-able or reuseable.  Preferably, each tray has a pair of heaters referred to herein as plate and bowl heaters and adapted to be operated by control means in either a continuous mode of operation or a rethermalization mode of operation.  In the rethermalization mode of operation the manually selected heaters associated with trays in all bays are operated for a predeter-mined period of time of, for example, 25 minutes, to rethermal-ize the food from a frozen or at least cold state to a tempera-ture on the order of 170°F.-180°F.  Thereafter, the heaters in predetermined bays are operated cyclically to hold the food at the desired temperature range.  During the initial predetermined period of the rethermalization mode the heaters may be operated on a continuous "on" basis or may be operated cyclically but preferably at a higher duty cycle and in the maintaining state which follows the predetermined period.  In another embodiment each tray may be provided with separate heaters, one being activated for normal operation and the other for rethermalization operation.  These heaters are selectively of different heating powers.

Granted: 1984-04-10
Abstract: A transaction execution system including at least one transaction terminal in communication with a host data processing system. A transaction at the terminal is authorized based, at least in part, upon correspondence of personal identification data entered by the terminal operator at a keyboard with account identification data read from an account card. When the personal identification data is not derived from the account identification data, the correspondence check is made at the host data processing system by comparison of encrypted identification data with validation data. The host may, upon failure of correspondence, communicate a conditional authorization message to the terminal, which enables the terminal operator to again attempt to enter the correct personal identification data. The host data base stores as validation data encrypted identification data, and only double encrypted identification data appears on the communication lines. SA9-79-037

Abstract: ROGERS, BERESKIN & PARR                C A N A D A     INVENTOR:     INVENTION:   HEAT EXCHANGER     ABSTRACT  OF THE  DISCLOSURE     A heat exchanger for energy efficient ventilation of buildings is described.  The heat exchanger has a core structure defined by a plurality of rectangular sheets of an extruded, cellular plastic material disposed in parallel, spaced-apart relationship.  The cells of the sheets provide a first set of flow paths extending between ends of the core tructure for use in passing cold fresh air.   The spaces between the sheets are sealed at each end of the core structure, and a cellular plastic sealing material is wrapped about the sides, top and bottom of the core structure and apertured at opposite ends to access the spaces, so that the spaces between the  sheets define a second set of flow paths for passing stale warm air.  A drainage aperture is provided in an inner face of a bottom sheet of the sealing sheet, where condensation tends to accumulate.  The drainage aperture permits condensation to escape through the cells of the bottom sheet.  The heat exchanger also includes a housing that elevates one end of the core structure even when the housing is horizontally oriented to facilitate drainage, and that provides manifolds to access the flow paths.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention is concerned with a metallurgical process in which fine-particle mineral coal is continu-ously blown into a shaft furnace.  According to the invention, the fine-particle mineral coal is mixed with at least one fine-particle solid carrier of carbon in the form of alkaline compost made of rotting household waste sewage sludge or a combination thereof, and the resulting mixture is stored in a bulk store, the quantity of the carbon carrier being sufficient to loosen the said mixture and to prevent it from caking and sticking in the bulk store.   The mixture is then withdrawn from the store and blown continuously into the shaft furnace.  The invention permits the use of inexpensive fine particle mineral coal and reduces the problems occurring during the storage in storage bunkers of fine mineral coals having a high ash content at least to a tolerable level while completely avoiding the need to fall back on expensive mechanical aids in order to prevent caking and sticking of the mineral coal.

Abstract: ABSTRACT      A communication system comprises a number of stations which are interconnected by means of a clock bus wire and a data bus wire which both form a wired logic function of the signals generated thereon by the stations.   During the clock pulses, the signal on the data bus wire is stationary; it may change between the clock pulses.  Start and stop conditions are formed by a signal combination between clock bus wire and data bus wire which is not per-missible in a data stream.  If there is more than one master station so that a composite clock signal occurs on the clock bus wire, the clocks of the relevant master stations are each time resynchronized to the actual transitions in the composite clock signal.
