Abstract: Abstract of the Disclosure:            An electron beam production and control assembly especially suitable for use in producing X-rays in a computed tomo-graphy (CT) X-ray scanning system is disclosed herein along with its method of operation.  This assembly produces its electron beam within a vacuum-sealed housing chamber which is evacuated of internal gases, except inevitably for small amounts of residual gas.  The electron beam is produced by suitable means within the chamber and directed along a path therethrough from the chamber's rearwardmost end to its forwardmost end whereby to impinge on a suitable target for producing the necessary X-rays.  Since there is residual gas within the chamber, the electrons of the beam will interact with it and thereby produce positive ions which have the effect of neutralizing the space charge of the electron beam.  However, there are a number of different arrangements disclosed herein which form part of the overall assembly for acting on these ions and reducing the neutralizing effect they would otherwise have on the beam.

Abstract: WORKPIECE PROFILE-FOLLOWING CONTROL SYSTEM         FOR CONDITIONING GRINDERS                             Abstract A control system for a workpiece conditioner grinder that compensates for bowing or curvature of the workpiece.  The curvature of the workpiece is initially determined by recording a set of grinding wheel position measurements when the grinding wheel is contacting the upper surface of the workpiece.  These measurements are used to calculate offsets from a fixed plane of reference, and the offsets are summed with vertical grinding wheel position command signals generated while the grinding wheel is grinding the sides of the workpiece.  The vertical position of the grinding wheel is thus modified by the offset in order to cause the grinding wheel to remove material in a longi-tudinally extending strip having a curvature conforming to the curvature of the workpiece.  Alternatively, the offset signal may be generated in real time and summed with the vertical position command signal.

Abstract: ABSTRACT     Regenerants for carburizing salt baths and a process for the production thereof Polymeric organic substances are known for the regeneration of salt baths for nitrating parts consisting of iron and steel, but these substances cannot be used in carburizing salt baths since they produce only small quantities of cyanide which is active in the carburization process, they cause the baths to foam and carbon residues are formed.  An excellent regenerant for carburizing salt baths may be obtained if polymeric organic compounds, having a total composition of [C6HxNy]z,are used, in which x represents from 3 to 5, y represents from 5 to 8, and z represent from 10 to 10,000.  These compounds are obtained by reacting formaldehyde with cyanamide and/or dicyandiamide and/or melamine and by pyrolytically decomposing the reaction product at a temperature ranging from 300 to 600°C.

Abstract: Abstract:        By using a low-frequency component of attitude data of an uncorrected image resulting from scanning the ground by means of a sensor mounted on a satellite, low-frequency distortion correction coefficients are calculated.  By using a high-frequency component of attitude data, a change rate is calculated.  From said low-frequency distortion correction coefficients and said change rate, distortion correction coefficients covering a high frequency as well are calculated.  By applying bidirectional resampling to the uncorrected image by using said distortion correction coefficients covering a high frequency as well, a corrected image is obtained.  If the underlap occurs during the reciprocating scanning by means of said sensor, iteration calculation for correlating the uncorrected image with the corrected image is repeated.          When picture elements thus correlated with each other are determined not to be positioned on an identical scanning line, said iteration calculation is terminated to reduce the time required for iteration calculation.

Abstract: ABSTRACT OF THE DISCLOSURE   Sector marks are selectively placed in each coarse servo track of  a  rotating  disk.    These  concentric  coarse  seek  tracks, pre-written  on  the  disk,  are  used  by  a  servo  system  for  the positioning of the read/write mechanism.   Coarse track read means simultaneously  sense  at  least  two  adjacent  coarse  seek  tracks.       Detection means sense the relative position of these coarse seek tracks within the sensing range of the coarse track read means, and this position information is used by the servo system to selectively control the radial position of the coarse track read means with respect  to the rotating disk.   The  sector marks written  in the coarse seek tracks are likewise detected, and a signal is produced indicating when each  sector  begins  and  ends.   An  oscillator  is locked to this sector signal such that a fixed number of cycles of the oscillator signal corresponds to the passage of one sector of the disk under the coarse track read means.  A counter is then used to  count  the  appropriate  number  of  cycles.   An  index  mark, representing a zero degree reference point,  is also placed in the coarse seek track.  When sensed, the index mark resets the counter.          The  count  contained  in  the  counter  thus  always  indicates  the rotational position (sector location) of the disk.

Abstract: ABSTRACT OF THE DISCLOSURE            An arrangement and method of controlling optimum chilled water temperature supplied to a process by a pump, the water being chilled by coolant in a coolant cycle having a compressor and a load valve, comprises first and second sensors for sensing a supply and a return temperature to and from the process.  A value is obtained for the amount of work done by the punpand the compressor with that value as well as the supply and return temperature values being supplied to a supervisory control.  The supervisory control operates to generate a reference temperature which is a function of the supply temperature but which is either above or below the supply temperature depending on a ratio between the difference in work and a change in the difference between the supply and return temperatures.  When the ratio is about zero this indicates the difference between supply and return temperature is at an optimum and the reference temperature is the same as the supply temperature.  When the ratio is negative, the reference temperature is below the supply temperature and when the ratio is positive the reference temperature is above the supply temperature.  The reference temperature is used in a temperature controller which is connected to the load valve for adjusting the setting of the valve according to a load demand signal which is chosen to be either the reference temperature if that is less or a demand value which depends on the amount of demand necessary for the process.

Abstract: A B S T R A C T            FOOTWEAR            A shoe must have a yielding sole in order to protect the bones of the foot and the leg, especially when the foot touches the ground. In order to improve such sho-es, oblique, elastic ribs (1) are mounted between the binding sole (3) and the wearing sole (2) so that  a bending of the ribs takes place when the foot touches the ground, by means of which energy is accumulated, which energy is released during the take-off by the straightening out of the ribs so that this energy can be utilized as a contribution to the energy of the foot.     The ribs (1) are cast together with the wearing sole (2) and form an angle (.alpha.) of approx. 40° to the horizontal plane, and are oblique from the binding sole (3) forward against the wearing sole (2). The ribs (1) are dimensioned according to the required yielding and elasticity, the dimensions, number, and angle (.alpha.) of the ribs corresponding to this.            The ribs (1) are preferably made of polyurethane on the basis of ether, which produces good elastic qua-lities. Finally, ventilating apertures (11) can be arranged between the binding sole and the space (9) between the ribs, so that air is pressed from the airspace upwards to the sole of the foot while walk-ing.

Abstract: ABSTRACT OF THE DISCLOSURE          A real-time recall feature for an engine data processor (20).  An engine mounted data processor (20) inputs a plurality of engine operating parameters from a gas turbine engine (10).  These parameters are fault checked and reformatted by the processor (20) before being output on a serial transmission channel (XCH) to an airframe mounted permanent recording apparatus (30).  A set of the most recent engine profiles are stored in a dynamic random access memory (DRAM) which is constantly updated by overlaying the oldest data with the most recent.  A switch (52) generates a signal (FRZ) to terminate storage of the profiles and freeze the contents of the (DRAM). The memory remains frozen having captured the most recent engine profiles associated with the generation time of the signal (FRZ) until unloaded over the channel (XCH) to recorder (30).  The output of the (DRAM) is in response to a signal (RPL) generated by switch (52).                         (Figure 1)
