Abstract: A polyvinyl butyral (PVB) resin has a meso/racemic stereoisomer ratio of from about 2.5 to about 5.0. A process for preparing this PVB resin is described. Manipulation of the PVB stereoisomer ratio can provide an additional method of controlling the physical properties of a plasticized composition comprising the PVB resin, in addition to or in lieu of changing additives or otherwise manipulating the components of the plasticized PVB resin composition.
Abstract: A method and device having a CCD in which charge multiplication is obtained by applying drive voltages to clocking elements and is arranged to derive the gain provided by the multiplication elements from at least first and second output signals. The CCD is operated at a first voltage or temperature setting, and then a second voltage or temperature setting and the output signals derived with the CCD imaging a substantially constant scene. The gain at a given voltage or temperature setting can then be derived as a function of the different operational voltage of temperature setting. The method and device can also derive the gain as a function of the rate of change of output signal with an operational parameter such as voltage or temperature.
Abstract: A process is disclosed for making CH2ClCF2CClF2. The process involves reacting CH2ClF with CClF?CF2 in an addition reaction zone in the presence of an aluminum halide composition having a bulk formula of AlClxBryF3-x-y wherein the average value of x is 0 to 3, the average value of y is 0 to 3?x, provided that the average values of x and y are not both 0. Also disclosed is a process for making CH2FCF2CF3 that involves reacting the CH2ClCF2CClF2 with HF in a fluorination reaction zone in the presence of a fluorination catalyst. Also disclosed is a process for making CHF?CFCF3 that involves dehydrofluorinating the CH2FCF2CF3.
Abstract: A fluorinated alkylalkoxylate, and a process for its preparation in which at least one fluorinated alcohol is contacted with at least one alkylene epoxide in the presence of a catalyst system comprising an alkali metal borohydride, and an organic quaternary salt.

Abstract: The present invention is based on the finding that a capacitance can be measured precisely and efficiently when, in a delta-sigma modulator having an operational amplifier, a first capacitor connectable to an input of the operational amplifier, and a second capacitor in a feedback branch of the operational amplifier, a reference signal source is connectable to the first capacitor, wherein the first or second capacitor may represent a capacitance to be measured. Due to the fact that, in contrast to what is conventional, no input quantity is measured and digitalized at the input of the delta-sigma modulator, but instead a defined reference signal source is coupled at the input and a device of the delta-sigma modulator itself represents the measuring quantity, an extremely compact circuit is provided allowing capacitances to be measured quickly and reliably, the measuring result being additionally made available in a digital form.

Abstract: A shoe outsole has a heel post extending outwardly therefrom. An outer heel cover has a hole for receiving the heel post in an assembled position. The heel post thus acts as a convenient positioning guide for the heel cover. A plurality of fluid-filled heel cushioning members at least partly surrounds the heel post between the outsole and the cover in the assembled position, for cushioning heel impacts during use of the footwear. A plurality of dividers on the outsole extend radially of the heel post, and position each cushioning member between a pair of the dividers. The dividers thus act as convenient positioning guides for the cushioning members. The cushioning members have different resistances to compression for adjustably cushioning heel impacts during use of the footwear.
