Abstract: ABSTRACT OF THE DISCLOSURE         An image processing system including a stored program processor especially suited for manipulating two dimensional binary data arrays, each array, for example, representative of an image, for the purposes of measuring basic geometric properties of the arrays, cross-correlating two arrays, and creating new arrays as a function of one or two other arrays.  The image processor pre-ferably operates in conjunction with a general purpose central pro-cessor unit (CPU) including a random access memory which provides the image processor with both the image data arrays and program commands defining the particular image process or operations to be performed with respect to the data arrays.  The defined image pro-cess normally involves accessing one or two data arrays from se-quential locations in the CPU memory.  As the data arrays are being accessed, they are being operated upon to, for example, create a third data array as a function of the first two data arrays, the third data array being stored back into the CPU memory.  Concurrently the three arrays can be measured in various manners with the measure-ments also being stored in the CPU memory.  Means are provided for concurrently performing an additional major processing function involving correlation between the first and second data arrays to, for example, determine the shape similarity and relative positional offset therebetween.  Additionally, the image processor is also concurrently able to analyze or measure the third image formed as function of the first two images.

Abstract: ABSTRACT OF THE DISCLOSURE         A transit concrete mixer includes a drum which is mounted for discharge either forwardly or reversely of the vehicle and has two sets of flights for two-stage concrete loading and discharging.  One set of flights is particularly useful for carrying the aggregate from the base of the drum upwardly along the major axis of the drum and a second set of flights is adapted for receiving the aggregate and transporting it through the remaining length of the drum to the discharge opening of the drum. Thus, for relatively stiff, low slump aggregates which are useful in paving and for formless type useage, the concrete mixer unit is fully adaptable for such low slump values.  Conversely, the same set of flights is adapted for charging and discharging relatively high slump values which are utilized for form type applications.  Additionally, the discharge opening of the drum is controlled in accordance with the slump of the discharging concrete mix or aggregate so that for relatively stiff and low order slump values the aggregate is dischargeable without impediment and, conversely, for more fluid, high slump aggregates, the discharge opening is control-lable by an adjustably placeable weir which precludes too rapid emergence of the slump for given drum rotations with the des-cribed combination of flights.  The transit mixer unit is, therefore, the first practicable all-purpose transit mixer.

Abstract: ABSTRACT OF THE DISCLOSURE     Sensor member having on it a ceramic crystal, is secured to a sieve or sieve frame of a combine harvester to be shaken with the sieve or sieve frame being so located that any grain which is discharged from the sieve and otherwise wasted will impact upon the sensor and cause an electrical signal to be transmitted by the crystal, the signal being amplified and transmitted to a readout station which enables the operator to immediately identify when grain is wasted. In being shaken along with the sieve the sensor presents a clean face to the grain, which might otherwise be partly obscured by chaff or other discrete material and this results in a higher degree of accuracy in the determination of wasted grain.

Abstract: ABSTRACT OF THE DISCLOSURE:           A method of transmitting liquid between separated activation compartments for biological water purification based upon the application of pressure induced by the stream of liquid in the individual activation compartments due to aeration of said liquid.  Such effect is achieved owing to the fact that the inlet holes of transmitting passages between the separated compartments are located in the area of lower velocity of flow of the liquid than the velocity of flow of the same at the outlet holes of the transmitting passages.  Such method is easily applicable particularly for vertical tanks.          The compensation of pressure losses in the individual compart-ments, and thus the ensuring of equal levels of liquid within these compartments can be carried out by means of the dynamic pressure of the flow of liquid in the activation area or by means of Bernoulli's pressure of the flow of liquid, or, possibly, by combining both these pressures.  In this way the air distribution within the aerated system can be simplified along with improved tank volume usage.

Abstract: LOW PROFILE MULTI-POLE CIRCUIT BREAKER HAVING        MULTIPLE TOGGLE SPRINGS                     Abstract of the Disclosure A multi-pole circuit breaker includes a wide toggle shaft which spans all of the poles of the breaker and which is electri-cally neutral.  The lower links of the toggle mechanism are made of phenolic or other insulating material which thus electrically insulates the wide toggle shaft spanning all of the poles of the breaker and makes the toggle shaft electrically neutral.  A plurality of short toggle springs may therefore be connected between the wide toggle shaft and a handle arm of corresponding width.  The plurality of short toggle springs provide as much tripping energy as the longer single or double toggle springs of prior art circuit breakers in which the springs are clustered together in alignment with one pole of the breaker to which they are electrically connected and whose polarity the toggle springs in such prior art breakers accordingly take.  Thus by providing a tripping mechanism which can utilize a plurality of short toggle springs in place of one or two long ones, a lower profile circuit breaker is possible.  In addition, the movable contact blade of each pole of the multi-pole breaker of this invention is biased independently toward a contact closed position.  Each contact blade is pivotally mounted to the lower end of its corresponding insulated lower toggle link, with the end of the contact blade opposite the contact end being biased in one direction by a cantilever spring to urge the contact end in the opposite direction to the contact closed position.  The biasing force is selected to permit the movable contact of each contact pair to separate by virtue of electrodynamics and thermodynamic "blow-apart" forces occurring during a severe short circuit in the phase in which such pole is connected.
