A free standing self contained device for bonding ultra thin metallic films, such as 0. 001 inch beryllium foils. The device will regulate to a predetermined load for solid state bonding when heated to a bonding temperature. The device includes a load regulating feature, whereby the expansion stresses generated for bonding are regulated and self adjusting. The load regulator comprises a pair of friction isolators with a plurality of annealed copper members located therebetween. The device, with the load regulator, will adjust to and maintain a stress level needed to successfully and economically complete a leak tight bond without damaging thin foils or other delicate components.

A logarithmic converting apparatus for converting a digital binary integer into logarithmic representation and for converting logarithmic representation into digital binary integer is disclosed. The apparatus determines the bit position of a leading non-zero bit of an integer, shifts the integer such that the leading non-zero bit is the leftmost bit. A look-up table receives the shifted integer and provides a number representative of the mantissa portion of the logarithm of the shifted number. An encoder receives a Point Set Input value, a scale value for said integer, and the number of binary positions shifted and generates the exponential portion of the logarithm of the integer. For converting logarithmic representation of a number into integer representation, the apparatus has a look-up table which receives the mantissa component of the logarithmic representation and provides a first number. A decoder receives the exponential component of the logarithmic representation and a Point Set Output value, a scale value for said integer, and supplies a shifted signal. The shifted signal is supplied to a shifter along with the first number and the shifter shifts the first number by the shift signal to produce the integer.

Speech signal analysis for data reduction, as stored for synthesis or recognition, is improved by features including: digital spectral analysis; reduction of channel data and bit allocation by selective summation of groups of contiguous data; using the mean average of the log amplitude to find the deviation for each channel; also using the instaneous shape of the mean value for each channel for pairs of adjacent frames, all combined to find a feature ensemble for each pair of adjacent frames.
