Abstract: An apparatus for making cotton candy comprises a supply of sugar and a heating device for melting the sugar into a molten form. A pumping device pumps the molten sugar to an extrusion device having at least one extrusion orifice. The extrusion device is operable to extrude a strand of molten sugar from the orifice which is solidified to form cotton candy.

Abstract: A process is described for removing polar compounds from an aromatic feedstock which contains polar compounds. The process comprises contacting the feedstock in an adsorption zone at a temperature of less than or equal to 130° C. with an adsorbent selective for the adsorption of said polar compounds and comprising a molecular sieve having surface cavities with cross-sectional dimensions greater than 5.6 Angstroms. A treated feedstock substantially free of said polar compounds can then be fed to an alkylation zone for contact under liquid phase alkylation conditions with an alkylating agent in the presence of an alkylation catalyst.

Abstract: A process is described for removing polar compounds from an aromatic feedstock which contains polar compounds and which is then used in an alkylation process. The process comprises contacting the feedstock in an adsorption zone at a temperature of less than or equal to 130° C. with an adsorbent selective for the adsorption of said polar compounds and comprising a molecular sieve having pores and/or surface cavities with cross-sectional dimensions greater than 5.6 Angstroms. A treated feedstock substantially free of said polar compounds is withdrawn from the adsorption zone and fed to an alkylation zone for contact under liquid phase alkylation conditions with an alkylating agent in the presence of an alkylation catalyst.

Abstract: A process for removing polar compounds from an aromatic feedstock containing polar compounds comprising the steps of:

Abstract: Positioning, by the use of a unitary construction, a breathalyzer and retina/eye-scanner a distance apart from each other that corresponds to the typical distance separating an individual's mouth and eyes, so that there can be positioned only one individual's face adjacent the unitary construction preparatory to the use thereof, which minimizes the use of two individuals, one to provide a sober breath to the breathalyzer and the other to provide a bogus retina scan of the identification of the individual using the breathalyzer.

Abstract: For a computer-monitored operation of a common carrier truck currently mandated by law to limit a driving shift to ten hours per driver to minimize accidents due to driver fatigue, replacing a manual input of the driver's identification per shift with a driver-identifying fingerprint sensor to provide verification of both driver and truck operation resulting from the inherent tamperproof accuracy of the computer and fingerprint sensor.

Abstract: Akylation product is contacted with a purification medium in a liquid phase pre-reaction step to remove impurities and form a purified stream. The purified stream may then be further processed by liquid phase transalkylation to convert the polyalkylated aromatic compound to a monoalkylated aromatic compound. The process may use a large pore molecular sieve catalyst such as MCM-22 as the purification medium in the pre-reaction step because of its high reactivity for alkylation, strong retention of catalyst poisons and low reactivity for oligomerization under the pre-reactor conditions. Olefins, diolefins, styrene, oxygenated organic compounds, sulfur containing compounds, nitrogen containing compounds and oligomeric compounds are removed.

Abstract: The procedure serves the purpose of molding a container from a thermoplastic material. After a temperature treatment a moldable object is fed to a blow station, which has a blow mold that is provided for the purpose of contouring the container. The temperature-treated moldable object is inserted into the blow mold. By feeding in high-pressure blow air, the moldable object is expanded. In addition at least one other pneumatic working step with low-pressure air is carried out, with this air being taken from a low-pressure air supply. The low-pressure air supply has a smaller pressure level than the high-pressure blow-air supply. After the moldable object has been expanded, high-pressure blow air streaming out of the molded container held in the blow mold is fed to the low-pressure air supply during a transition phase. In the region of the low-pressure air supply a pressure monitoring is carried out for the purpose of defining a maximum low-air pressure to be provided.

Abstract: The procedure is designed for the pneumatic operation of a device in which at least one structural element is pneumatically actuated. The actuation is done by primary working air, which is fed to the pneumatic structural element from a primary working-air supply. In addition to the primary working-air supply at least one secondary working-air supply is used, which is provided with a lower pressure level than that of the primary working-air supply. After the execution of a working operation by a pneumatic structural element by means of a compressed-air supply from the primary working-air supply, during a transition phase a venting into the secondary working-air supply is carried out. After the transition phase a venting of the first pneumatic structural element vis-a-vis an ambient pressure is carried out. A second pneumatic working operation is powered by air from the secondary working-air supply.

Abstract: A distributor system for uniformly directing vapor and liquid across the surface of a fixed bed of solids in a downflow reactor comprising a distributor tray, and a plurality of open-ended downpipes extending through the tray. A first array of the downpipes has a plurality of vertically spaced elevations of holes above the level of the tray. A second array of the downpipes has at least one elevation of holes at substantially the same height above the level of the tray as one of the upper elevations of holes in the first array of the downpipes. But, the second array has no elevation of holes corresponding to the lowermost elevation of holes, and possibly other lower elevations of holes, in the first array of downpipes. The absence of the lowermost holes in the second array of downpipes causes the liquid flow rate through the distributor tray at a given liquid height to be reduced when that liquid height falls below the elevation of the holes second from the bottom in the first array.
