Abstract: METHOD AND APPARATUS FOR LOW-DUST DISCHARGE OF PARTICULATE MATERIAL THROUGH A NOZZLE     Abstract of the Disclosure A method and apparatus are disclosed for low-dust discharge of particulate material such as grain.  The apparatus provides a nozzle having a hollow body with an inlet at the top and an outlet at the bottom.  An impeller is mounted inside the body in an outwardly and downwardly flaring region below the inlet.  A fluid stream of the particulate material drops through the inlet and impinges on the impeller which deflects or throws the particles outwardly within the flaring region of the nozzle.          The coarser, heavier particles have more outward momentum than the lighter, finer particles and are concentrated toward the wall of the nozzle below the impeller while the lighter, finer particles are concentrated toward the center, so that a rough separation is made and stream density is increased.  A compacted downwardly moving mass is accumulated within the nozzle and is discharged through the outlet at controlled rate as a denser, relatively dust-free stream in open air.

Abstract: ABSTRACT OF THE DISCLOSURE           A motor-driven grinding machine or unit has been provided to enable consumer-selected food items, such as nut kernels and grains to be quickly, uniformly and efficiently ground to a desired consistency in his or her presence.  The machine has a chute with a motor-controlling lid that is adapted to receive selected food items and to feed them to a rotating auger shaft which extends into a processing housing.  Food items are then advanced substantially radially outwardly between a pair of heads having opposed disc-like grinding surfaces, each of which has a set of inner, widely spaced-apart, relatively coarse teeth and an outer, relatively finer, closely spaced-apart set of teeth between which the food is advanced while the auger shaft rotates one of the heads and the food items are being ground and advanced between the surface strategically designed and positioned in a positive manner to reduce them to a desired uniform particle size. Slot portions between the teeth of the inner and outer sets provide outward flow paths for the food being ground that avoid clogging and excessive heat build-up, while assuring a full and uniform grinding and an outwardly advancing flow of the food between the pair of heads.  The food as thus ground into a butter, meal or flour is moved peripherally forwardly into a front portion of the processing chamber, with a wiping action being effected by the rotating head for delivering the processed food through a down-spout or open portion in the housing.  External means is provided for adjusting the axial position of the rotating head to control the operating relation between the teeth of the cooperating opposed grinding surfaces.

Abstract: ABSTRACT       This invention is a mechanical system of appa-ratus for heat recovery from stacks, chimneys, flues, etc. using a special heat exchanger design mounted at the apex of such stacks. Sensible heat as well as the latent heats of moisture in fuels and that in vapor pro-duced as a combustion product can be scrubbed out. The heat is transferred to liquid and then transferred by pump to whatever location desired. The natural draft is not impaired because the column of hot gases is not affected. The use is to effect economies wherever fuels are fired and to reduce environmental contamination.

Abstract: ABSTRACT OF THE DISCLOSURE A digital speed control system for a sewing machine comprises a digital speed setting device which responds to manual depression of a foot pedal by generating a digital position signal.  A variable frequency divider divides the frequency of speed related pulses so that its output frequency is an integral submultiple of the input frequency, which is variable as a function of the digital position signal.  A period detector senses the interval between pulses that occur successively at the output of the frequency divider and generates binary data representing the sensed interval.  The interval-representing data is translated into a second period data in an arithmetic unit according to a predetermined transfer function.  The arithmetic unit provides cor-rection of the most recently sensed pulse interval according to the direction and amount of the deviation of the most recent pulse interval with respect to the preceding pulse interval, whereby the second period data is accordingly modified by an amount proportional to the rate of sewing speed variation.  A pulse generator translates the second period data into a pulse for activating a magnetic clutch or a magnetic brake depend-ing on a sign of the second period data to accelerate or decelerate the sewing machine.

Abstract: DIGITAL SCALE                    Abstract This invention relates to an improved digital scale arrangement which employs apparatus for generating an electrical analog signal representing the weight on a scale mechanism.  The analog voltage is then inverted to a digital representation of the weight on the scale under control of a microprocessor or microcomputer.  The microcomputer then further processes the digital representation of the weight on the scale and causes an indication to be displayed on a display arrangement. In accordance with the present invention, an automatically operating over all and combined verification arrangement is provided for verifying the correct operation of both the analog portion and the converting portion and the digital portions of the system.          In order to verify the operation of the entire arrangement, a verifying signal of predetermined magnitude is injected into the analog portion of the system.  This signal passes through the analog portion and then is converted by the A to D converter to a digital signal representing a same value.          This digital signal is then compared with a predetermined reference digital signal corresponding to the predetermined analog signal injected in the analog portion of the system.          If the two digital signals correspond then the analog verification test is considered satisfactory and the scale is thereafter available for another weight measurement.  If the correspondence between the two signals is greater than the first predetermined range but less than the second range, then a stored span control factor is modified so that when the weight, multiplied by this span control factor, will more nearly correspond with the stored value of the corresponding digital value of the analog signal injected in the system.  Thereafter the verification routines are repeated until the two digital weights correspond within the predetermined tolerance of limits.  During this time an analog verifying indication is displayed on a display apparatus.  If the correspondence between the two digital weight signals is greater than the second predetermined tolerance limits then an error signal is displayed and the scale rendered inoperative until power is removed or until the difficulty is corrected.  Provision has also been made to initiate an overall combined verification signal by means of an AV key which may be manually operated by the scale attendant.  The response to the operation of this key is substantially the same as to the automatic initiation of the verification cycle as described above.
