Abstract: A method for producing acetophenone comprising: treating one or more alkylbenzenes comprising s-butylbenzene to produce a feed comprising phenol and acetophenone; separating a crude phenol stream from the feed under crude phenol separation conditions effective to produce a crude phenol heavies; and, separating an acetophenone stream directly from the crude phenol heavies under azeotropic distillation conditions.

Abstract: A method of manufacturing a phenol product having a reduced concentration of a contaminating reaction by-product. The method includes contacting a phenol stream, having a concentration of the contaminating by-product, by contacting the phenol stream with an acidic catalyst under suitable purification reaction conditions. Also included is a composition comprising a sec-butyl benzene derived phenol product that has been purified by the removal of certain undesirable reaction by-products.

Abstract: A method of purifying a phenol stream that contains a concentration of a contaminating compound is provided. The phenol stream is treated or purified by contacting the stream, under suitable process conditions, with a treatment catalyst that has a low silica content but comprises alumina and a Group VIA metal.

Abstract: A system and method of processing laundry by the determination of surface tension in a dynamic environment for surfactant concentration in industrial laundry applications. The dosage system is able to control the surfactant concentration for a recycle wash tank and preferentially the washer tank using surface tension measurements, temperature control, and correlation to the percentage of active matter based on a full dose of a commercial surfactant for the wash runs. The dosage system preferably uses a surface tensiometer able to monitor surfactant levels and to constantly dose surfactant for use in subsequent washes.

Abstract: A device for engaging and disengaging the driving mechanism of an automatic slide gate. The device uses a series of two levers to develop a substantial mechanical advantage in the operation of a dog clutch. An actuating lever is positioned so that it may be operated by the user's foot, eliminating the need for any auxilliary levers or tools.

Abstract: An apparatus which is designed to improve the art of dallying. The apparatus is designed and configured to simulate the front end of a conventional saddle. This dallying apparatus comprises a front end connected to a back end via a middle portion. The front end includes the horn which extends upwards from the horn shoulder support, while the back end is secured to the removably secured to the user. This will provide for the horn to be situated in front of the user at the appropriate distance due to the middle portion. Accordingly, once attached, the user can practice and perfect the art of dallying.

Abstract: A saddle type pipe clamp that is adjustable to a wide range of pipe sizes includes a saddle portion formed by a pair of complementary saddle elements of channel stock. Each saddle portion includes curved clamping surfaces, and a bolt hole and slot in the closed edge. An elongate threaded rod is provided which is manually bent around a pipe to form a U-bolt. The saddle elements are adjusted to fit the U-bolt, and installed with washers and nuts. The ends of the U-bolt may be trimmed after installation.
