Abstract: ABSTRACT OF THE DISCLOSURE         A dynamic internal fitting system with a movable foot bed      mounted in the interior of a ski boot    is disclosed for controlling foot movement in the boot.  The movable foot bed      is hinged at its toe to the sole of the boot     by a hinge.       The opposite end of the foot bed      is coupled to an adjusting buckle      by means of a cable.       A pair of adjustable strap members are provided for engaging the upper surface of a skier's foot.  Both the position of the foot bed      and the straps         may be varied for adjusting the fit of the boot.  In use, as the cuff is moved toward the toe of the boot, the foot bed      is raised, tightening the fit of the boot.  When the cuff is moved toward the heel of the boot, the foot bed      is lowered in the boot, loosening the fit of the boot.

Abstract: Abstract A fluid pressure responsive transducer is disclosed of the kind having a thin flat vibrating diaphragm serving as a wall of a continuous pres-sure chamber for converting a variable fluid pressure magnitude directly into a variable frequency electrical signal.  The thin flat diaphragm, secured only at its periphery to the chamber, becomes progressively stiffer as it is pro-gressively deformed by fluid pressure loading more and more from its flat or unstressed position.  A dual cavity configuration of the pressure chamber is formed by a rigid divider wall with a restricted passage therethrough.  The effects of disturbing acoustic waves which might otherwise be generated in-terior of the fluid chamber or within  pneumatic lines coupled thereto are thus suppressed.

Abstract: ABSTRACT OF THE DISCLOSURE        A nozzle ring of an extruder for blowing tubular plastics film is divided into correcting sectors provided with adjusting elements.  The thicknesses of the blown film are measured over the circumference thereof and a number of film sectors of equal cross-sectional area corresponding to the number of correcting sectors is established from the measured thicknesses.  Assuming that the film sector of maximum or minimum thickness has been extruded in the correct position for the purpose of determining the correcting sector associated with the  film sector, the subsequent film sectors of equal cross-sectional area are in turn allocated to successive correcting sectors.  The throughput and cross-sectional area or temperature of the respective correcting sector is adjusted until the circumferential lengths of the film sectors are equal.

Abstract: FREQUENCY DEVIATION TESTING AND ADJUSTING SYSTEM by Alistair W. Taylor Josef L. Fikart David Thompson Abstract of Disclosure Deviation of a frequency modulated oscillator is set by applying a square wave test signal to the input of the oscillator so as to generate a predetermined amount of symmetrical periodic frequency shift above and below the carrier when the deviation is correctly set. The output of the frequency modulated oscillator is divided down so as to be within the range of a programmable divider which is an element in the automatic phase control circuit of the oscillator.  The carrier frequency of the oscillator is set by program switches which are connected to an interface logic unit that provides the control information to set the divisor of the programmable divider.  The divisor is set to obtain, at an output of the divider, a binary signal having a predetermined pulse repetition rate.  During testing, the square wave test signal is also applied to a control input of the interface logic unit, and the test signal is used to adjust the divisor so as to provide at the output said binary signal having the predetermined pulse repetition rate when the modulated signal is applied to the input to the programmable divider and the deviation is correctly set.  A reference oscillator provides a separate binary signal which has a pulse repetition rate equal to that of said predetermined pulse repetition rate.  These two binary signals are compared in a deviation test circuit and the modulation sensitivity of the frequency modulated oscillator is adjusted until the difference between the two binary signals is at a minimum.
