Abstract: A method of increasing the lifetime of a hydro-oxidation catalyst comprising, preferably, gold, silver, or mixtures thereof, and optionally one or more promoters, on a titanium-containing support, such as a titanosilicate or titanium dispersed on silica. The method of the invention involves contacting the catalyst support with a hydroxy-functionalized organosilicon compound, a carboxy-functionalized organosilicon compound, or a mixture of hydroxy- and carboxy-functionalized organosilicon compounds, such as, sodium methyl siliconate or (2-carboxypropyl)tetramethyldisiloxane. The contacting is preferably conducted during deposition of the catalytic metal(s) and optional promoters(s) onto the support. A catalyst composition and hydro-oxidation process utilizing the silicon-treated catalyst support are also claimed.

Abstract: Said invention relates to methods for the out-of-furnace processing of metal for the iron and steel industry. Said invention makes it possible to expand an active zone of coverage of metal volume by gas or a gas-powder mixture, thereby reducing the time required for obtaining a homogenised composition of metal without increasing the quantity of supplied gas, i.e. to solve the problem of the intensified steel feeling by gas or gas-powder bubbling. The inventive method for feeling steel consists in blowing steel from the bottom by gas or a gas-powder mixture through at least two designed blowdown devices diametrically arranged on the opposite sides of a ladle. The bubbling is carried out alternatively through the devices arranged on the opposite sides of the ladle, a pressure for preventing the flowing of metal in the device which is not used at given moment being maintained therein. The alternative operational time of the blowdown devices is increased proportionally to the increase of steel in the ladle, the volume of supplied gas being unchangeable when the gas or gas-powder mixture supply is switched from one blowdown device to another.

Abstract: A novel method and apparatus of detecting unique items as they are inserted into a product packaging system that is easily adaptable to current product packaging and prize insertion systems. A number of different types of sensors may be used in conjunction with the insertion device to detect the unique prize before it is inserted into a product packaging system. The sensor used will vary depending on the particular application. Sensors that may be used include a capacitive proximity sensor, a thickness sensor, a reflectivity sensor, a transmissivity sensor, a stiffness sensor, a color sensor, or even an odor or chemical sensor. Ideally, the type sensor used will detect a feature of the unique item that is easily distinguishable from other items being inserted. Once the sensor detects the prize and generates a signal, this signal can be used to perform a variety of useful functions. In one embodiment of the invention, the signal is used to control a foreign matter detector (FMD) during the insertion of unique prizes that would ordinarily trigger the FMD. After detecting the unique prize, the controller for the insertion device shuts down the FMD for a pre-determined period of time to allow the unique prize to pass through without triggering the FMD. The controller may also increase a counter each time one of the unique prizes is detected to keep track of the number of unique prizes inserted. Once the unique prize passes through, the FMD is turned back on so that foreign objects may again be detected. The amount of time that the FMD is turned off is minimized.

Abstract: A process is performed for testing the quality of a unit such as an electromotor, which has at least one mobile part, which is mobile within a given frequency range with varying frequencies and is capable of exciting the unit to oscillate. In the method, a frequency of the mobile part at least within a first interval of the frequency range is varied with a first rate of change. The frequency of the mobile part within at least a second interval of the frequency range is varied with a second rate of change. The second rate of change is lower than the first rate of change. The oscillation amplitude of the unit is recorded and the unit is assessed as useful or unusable by evaluation of the recorded oscillation amplitude.
