Abstract: ABSTRACT OF THE DISCLOSURE    The present invention relates to a method and apparatus for non-destructive comparative investigation of physical characteristics affecting the reluctance of different parts of a body having magnetic permeability.          In accordance with the present invention a first saturating magnetic flux is induced in the body or a part thereof giving rise to a flux distribution pattern determined by the reluctance of the body or part thereof which in turn is determined by the physical character of the body or body part.  A second magnetic flux is also induced generally opposing the first magnetic flux in a selected region of the flux distribution pattern outside of the body or body part while maintaining substantial first flux saturation of the body or body part, such that any resultant magnetic flux in that region is at a readily measureable flux level.  Also provided is a detector for detecting along the body either variances from that flux level with the second magnetic flux being maintained substantially constant or variances of the second magnetic flux with the resultant magnetic flux being maintained substantially constant.

Abstract: Abstract of Disclosure The invention concerns a procedure for drawing water from a ground water store in such manner that the water obtained will contain the least possible amount of iron or manganese compounds, of hardness-inducing salts or of other detrimental impurities occurring in the ground water. The procedure is intended for use in those cases commonly encountered in practice where there is stratification in the occurrence of impurities in the ground water, and according to it at least two separate lifting pipes are inserted in the soil in different layers in accordance with the way in which the contents of impurities vary in different layers. From the lifting pipes water of different quality is then obtained, and the invention implies that water is simultaneously drawn with both lifting pipes, but only the water from that lifting pipe is conducted to normal consumption which is of better quality. The significance of the lifting of inferior quality water lies therein that thereby is reduced the water mixing between different layers, whereby the quality of the water conducted to consumption is constantly good.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of and apparatus for detecting ends of successive fly strips connected end to end by a slide fastener chain.  The successive fly strips, with their first flaps overlapping a tape of one fastener stringer and with their second flaps overlapping the other fas-tener stringer, are fed lengthwise along a straight path.          Then, the second flaps are folded over the respective first flaps as the fly strips pass through a folder extending through a fixed point on the straight path.          During this folding, a trailing end of the preceding second flap is temporarily deflected so as to provide a relatively large triangular space between confronting ends of an adjacent pair of the second flaps when the same confronting ends arrive at the fixed point.          Finally, a detector senses the presence of the triangu-lar space, which indicates the arrival of confronting ends of an adjacent pair of the fly strips.

Abstract: A-LAW PCM DECODER Abstract of Disclosure An integratable A-law PCM decoder that is relatively insensitive to parasitic and stray capacitance effects and that requires a total capacitance of only 32 times the normalized capacitance Co of the smallest capacitor thereof.  The decoder comprises a source of positive and negative reference voltages; a differential input operational amplifier having its non-inverting input connected to ground; a storage capacitor CC=16Co connected as a feedback capacitor between the inverting input and the output terminals of the amplifier so that they operate as a voltage source; binary weighted capacitors C1=Co, C2=2Co, C3=4Co and C4=8Co; and a second unit weighted capacitor C5=Co.  Switch means alternately connects one and other sides of C1-C5 (1) between ground and either a  reference voltage or ground, in accordance with characterizations in a PCM coded digital input word for sampling charge, and (2) between one side of CO and ground for transferring charge to CO for the first segment associated with a PCM word, and across CO for redistributing charge on the capacitors for other segments of the designated polarity. The resultant analog signal established on CO in the eighth segment is sampled prior to resetting the charge voltage on CO to substantially zero volts and receipt of the next PCM input word.

Abstract: IMPROVED STUFFING METHOD     ABSTRACT OF THE INVENTION         A method of stuffing food product into controllably premoisturized shirred casing using a stuffing machine designed for use with more pliable, fully soaked casing.  An internal sizing ring is used to prestretch the premoisturized casing to about its recommended stuffed circumference which significantly reduces stuffing pressure while still achieving the desired stuffed size.  The magnitude of the holdback force, and thereby the stuffing pressure, is adjusted by set-ting the distance between the sizing ring which stretches the casing and a sealing ring which prevents back flow of meat emulsion onto the stuffing horn.  After an encased product length is stuffed, and before the gathering and stripping operations associated with the clipping cycle, the sealing ring is advanced away from the sizing ring which serves not only to assist in the advance of additional casing for the gathering operation, but also to reduce the holdback force produced by the sizing ring so that additional casing is more easily drawn from the supply to reduce product pressure buildup during gathering, separating and clipping.

Abstract: Abstract Steam is added to the air that passes through the dense bed of the deactivated coked catalyst. Steam acts by removing adsorbed heavy hydrocarbons and reacting with the coke to yield carbon monoxide. The overall effect is to lower the regenerator temperature by removing oxidizable material and convert coke to carbon monoxide and hydrogen via endothermic reaction. This allows operation at higher Conradson carbon feed (10-14% Conradson carbon). Air is added at the bottom of the lower regenerator and also an additional air inlet is placed in the upper part of the lower regenerator section.
