Abstract: ABSTRACT OF THE DISCLOSURE  The invention relates to a container for flowable or otherwise extrudable materials, the container having a discharge barrier which comprises a dividing wall dividing the container space into an outer chamber which is in communication with a dispensing  opening of the container and into a storage chamber in which the contents can be subjected to pressure for dispensing from the opening and can thereafter again be relieved of pressure. The dividing wall is formed with a membrane section having at least one valve opening which upon pressure loading of the membrane section from the side of the storage chamber opens against a restoring force exerted by a membrane mounting and which upon relief from pressure automatically closes again under the restoring force. The dividing wall is also formed with a holding element which is connected to the container in a manner that takes up manufacturng tolerances.          Additionally, the dividing wall is formed with the mounting for its membrane section, the mounting being formed so as to be of relatively stable shape and being itself carried by the holding element. In the result, the mounting carries the membrane section in manner largely uninfluenced by the connecting conditions between the holding element and the container.

Abstract: Abstract Reforming catalysts and other hydrocarbon conversion catalyst containing a platinum group compo-nent on a porous inorganic oxide base, such as alu-mina, which catalyst have become inactivated by carbo-naceous deposits in a fixed bed hydrocarbon reforming system having sulfur-contaminated vessels and/or conduits in the flow path upstream from the catalyst beds are regenerated in situ without diversion of the flow stream of the regenerative gas, such as by expensive high pressure valves.          Prior to removal of carbonaceous material from the catalyst, metal sulfides in the metal surface of the portion of the processing apparatus upstream of the first reactor are converted in a separate oxida-tion step to sulfur dioxide, SO2, without substantial oxidation to sulfur trioxide, SO3, This is done by maintaining a low water vapor concentration of not more than about 0.1 mol percent in the oxygen contain-ing regenerating gas so that sulfur dioxide released into the regenerating gases by conversion of metal sulfides to metal oxides occurs without excess oxygen or water vapor being present in the effluent gas which passes through the catalyst; preferably, such sulfur removal step is performed at a temperature of from about 750°F to 1100°F.  After the sulfur content of the effluent gas from such conduits and vessels is reduced to substantially zero at temperatures of up to abut 1100°F, the gas temperature is reduced to less than about 800°F and the oxygen content increased to decoke the catalyst.  By removal of substantially all sulfides before such catalyst regeneration, complete regeneration of the catalylst is facilitated for subsequent redispersion of the metal components.     Sulfur trioxide formation is suppressed by absence of sulfur dioxide in the presence of water in the cata-lyst bed and a resulting reaction to sulfate in the catalyst base is avoided.  Such sulfate interferes with redispersion of platinum on reforming catalyst or maintaining alkali, or alkaline earth, metal compo-nents on zeolite surfaces.

Abstract: ABSTRACT         The invention relates to a coin sorter apparatus for sorting a group of mixed coins by denomination and automatic-ally terminating the sorting process in response to a sensed operating parameter.  Sorting is provided by a stationary disk and a rotating disk positioned sufficiently proximate to one another so that when the group of mixed coins are dropped into the center opening of the stationary disk, they are rotated by the rotating disk and guided by the stationary disk on a radi-ally outward spiral sorting path which exits each denomination of the coins at discrete locations along the periphery of the stationary means.  As the coins are sorted, a sensing means provides signals indicating the presence of a predetermined condition.  A bridge guide and a diverter guide, which are part of the stationary disk, are responsive to the signals from the sensing means to redirect the radially outward sorting path of the coins to a radially inward path so as to terminate the sorting process.  Optionally, a circuit responsive to the sensing means controls the application of power to the motor powering the rotating disk of the sorter apparatus and cuts off that power, when the sorting process is terminated in order to prevent abrasion of the re-circulating coins or damage to the sorter apparatus.

Abstract: Abstract A brake is provided for twin wheel casters.  A brake lever extends between the wheels and is depressed by a toe.  This rocks a link through a toggle position and presses a sheet metal brake shoe of generally W-shape against the inner drum or surface of the wheel flange to lock the wheel against rotation.  Reverse movement of the lever is effected by a toe to unlock the brake. Edges of the sheet metal brake shoe impinge against the inner surface of the wheel flanges to lock the wheel, and locking action may be augmented by serrating the inner surface of the wheel.
