Abstract: ABSTRACT OF THE DISCLOSURE         A method of and an apparatus for producing processed foodstuffs by passing an electric current to foodstuff materials including a container of insulating material open at opposite sides for receiving a food-stuff material suitably permeated with a salt solution which is placed in the container and held between a pair of electrode members located at the opposite open sides of the container.  An annular coil is arranged around the container.  As electric currents are passed simultaneously through the annular coil and between the nail of electrode members, Joule heat is generated in the foodstuff material to thermally treat and sterilize the foodstuff material while lines of magnetic force are produced and applied to the foodstuff material in such a manner that an AC magnetic field exerts influences on the electric current flowing through the foodstuff material, to render substantially uniform the temperature distribution in the foodstuff material and increase the amount of inosinic acid or glutamic acid therein.

Abstract: ABSTRACT OF THE DISCLOSURE          An improved architecture for a computerized branch exchange particularly for a time division multi-plexed bus used in the exchange.  An intershelf bus in-cludes a unidirectional source bus which receives sig-nals from expanders and a unidirectional destination bus which transmits signals to the expanders.  The expanders, through another bus, communicate with line cards which interface with telephone station sets, commercial lines, etc.  A time division multiplexed controller updates distributed connection tables contained in each of the expanders and controls the flow of data onto and from the unidirectional buses.  The distributed connection tables eliminate the need to broadcast addresses during each time slot.  The arrangement is particularly useful in reducing blocking associated with prior art bidi-rectional buses.

Abstract: ABSTRACT OF THE DISCLOSURE Emulation method and apparatus allowing a first system, which is not designed as a functional duplicate of a second system, to emulate the second system.  The input/output structure of the second system is emulated in the first system by means of routines stored therein and which direct the already existing input/output structure to operate in the same manner as the input/ output structure of the second system.  The emulation routines are in turn invoked through the non-maskable interrupt mechanism of the first system by a modification thereto which detects the occurrence of "foreign" input/output requests; that is, input/output requests occurring in programs originally written for the second system and which are not normally recognized by the first system.  The input/output structure of the first system includes input/ output devices having ports occupying a first range of the system address space and the input/output devices of the second system have ports located within a second, differing range of address space.  In the foreign requests detector a comparator compares input/output request port addresses to the range of port addresses occupied by the system input/output devices and indicates when a port address is within the range of address space occupied by the system input/ output devices.  The foreign request detector generates a non-maskable interrupt to invoke an input/output emulation routine upon the occurrence of input/output requests which do not normally fall within the range of input/output ports supported by the first system.

Abstract: ABSTRACT OF THE DISCLOSURE           A fluid flow meter using a pair of temperature-variable resistance elements as detectors.  Both elements are exposed to the fluid flow and supplied with a series of current pulses.  The pulses supplied to one element, the reference element, are of very short duration so as to have no appreciable heating effect; the pulses supplied to the other element are of longer duration and are controlled so as to maintain this element at a fixed temperature differential above the other element, which remains at fluid temperature.  The pulse width of the longer duration pulses is a measure of the flow rate of the fluid.  Since the relationship between heat dissipated in the element and fluid flow varies with fluid temperature, the voltage pulses across the reference element are used as a measure of fluid temperature to compensate for this variation in calculating the exact fluid flow rate.

Abstract: Mo-2679 LOW VISCOSITY OIL BASED PESTICIDE COMPOSITIONS           ABSTRACT OF THE DISCLOSURE The present disclosure is concerned with a technique for producing storage stable, non-caking, low viscosity pesticidal concentrates and the compositions so obtained.  The technique involves milling a solid biologically active compound in a low viscosity aliphatic petroleum fraction in which it is slightly soluble until it has an average particle size of less than about 10 microns at a temperature in excess of about 40°C in the presence of a high or ultra-high surface area silica and lecithin.  The milling is conducted in such a manner as to avoid melting any significant portion of the biologically active compound undergoing milling.  The concentrate so obtained, typically display room temperature viscosities between about 20 and 2,000 cps and contain between about 120 and 480 grams per liter of biologically active compound.  These compositions are more redispersible and have a lower viscosity than similar compositions with equivalent concentrations of biologically active compounds which were obtained by milling at ambient temperature.  There are suitable for either direct application or application after dilution in oils or water to any large area such as agricultural fields or forests which are typically treated with pesticides or growth regulants.

Abstract: Abstract of Disclosure A mobile storage system includes an anti-roll safety brake for preventing undesired rolling of a movable carriage.  The anti-roll brake is engaged continuously so that a portion of the power required to move a carriage is expended in overcoming the friction force of the brake.  Upon removal of the power source, such as de-energizing an electric drive motor, the anti-roll brake prevents all unpowered rolling of the carriage, and it continues to hold the carriage in place until the drive motor is again energized.  The anti-roll brake is particularly useful in mobile storage systems in which the guide rails cannot be installed in a level attitude.
