Abstract: Abstract of the Disclosure A television horizontal oscillator for use with a video source having a step change in the phase of the horizontal synchronizing pulses occurring at the vertical rate uses a phase-lock loop including a low-pass filter having a controllable filter characteristic. The control input of the filter is coupled to a source of vertical deflection rate signals and the filter attenuation is varied at the vertical rate.  A delay arrangement including a ramp generator and a comparator delays the variation of the filter characteristic relative to the vertical synchronizing signal.

Abstract: ABSTRACT OF THE DISCLOSURE         This application is directed to a process for the rapid blanching or sterilising of foodstuffs in particulate form.   The foodstuffs may be fruit, vegetables, meat or fish.          The process comprises rapidly applying heat at relatively high temperature to penetrate the outer portion of the article by means of hot steam and/or gas, on which the particle may be fluidised, or not, in a pressure vessel, and then holding the heated particle to equilbrate adiabatically throughout the sterilising temperature for the time to inactivate or destroy the microorganisms and enzymes whilst in transit through an insulated pressure zone.  The temperature is subsequently dropped and the product is cooled rapidly and is packed asceptically.

Abstract: ABSTRACT OF THE DISCLOSURE A bus bar with three phase conductors and one neutral conductor is engageable by an adapter in the shape of an elongate plug designed to connect an external circuit across the neutral conductor and selected phase conductor. The adapter housing contains two parallel shafts A, B each carrying a resilient contact blade, these blades being retracted into the housing in a disengagement position and being extendible by rotation of the respective shaft, through 90°. A locking slide between the two shafts prevents rotation of shaft B until shaft A has been rotated to engage its blade with the neutral conductor whereupon shaft B may be rotated, in one of two axial positions, to bring the other blade into contact, with the selected phase conductor whereby shaft A is locked in its engage-ment position. Shaft A also carries tongue-shaped detents which in its engagement position enter grooves in the bus bar to prevent untimely withdrawal of the adapter.

The meat dehy-drator comprises a circular pan member and a circular grill mem-ber contacting said pan and supported above a bottom surface of the pan.  A cylinder member which opens upward and downward and has upper and lower rims is mounted on bracket means of the grill to thereby define a cylindrical dehydrating chamber above the grill and spaced apart from the grill to provide an opening between the lower rim and the pan member to allow air passage therebetween.  A circular lid cover is also disclosed movably mounted at the upper rim of the cylinder member to define a top of the cylindrical chamber disposed below.  The lid cover includes means for mounting a heating element to extend from the lid into the cylindrical chamber to provide the heat source for the dehydration of meat.  The process is disclosed utilizing the meat dehydrator which includes the steps of slicing raw lean meat into strips and then optionally marinading the strips in a seasoning salt solution.  The meat strips are then positioned on the grill inside the cylindrical chamber adjacent the bottom.  The ambient air inside the chamber is then heated by the heating element means to a temperature of from about 150° to 200°F. which is maintained inside the chamber for a continuous period of time from about four to six hours.  A dehydrated meat comestible is thereby produced by the utilization of the disclosed apparatus and process having the moisture removed to provide a preserved tasteful food product.

Abstract: SPRAY OR ATOMIZING NOZZLE                ABSTRACT OF THE DISCLOSURE            A spray or atomizing nozzle is provided.  The nozzle comprises a vortex chamber, an outward-flaring outlet orifice and a movable spray-control body.  The spray-control body, in the non-operative state of the nozzle, rests on the flaring rim of said outlet orifice, while in the operative state the spray-control body, being impacted by the liquid issuing from the outlet orifice, is slightly lifted off the flaring rim of the outlet orifice, facilitates deflection of the impacting liquid outwards and produces a droplet spraying effect. Due to the negative-pressure zone created in the vortex chamber, the spray control body is maintained floating in a position of equilibrium at a close distance from the orifice rim, whereby the droplet-size spectrum of said spray is controlled.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to the production of suspensions or solutions of cyanuric chloride in aqueous organic solvents at high speeds of mixing and low production temperatures and thus with a low degree of hydrolysis by injecting liquid cyanuric chloride through a nozzle, which is installed in the upper end of a mixing device, in a countercurrent to the solvent which rises upwards from a nozzle or nozzles and is injected above the breast-like taper in the lower open end of the apparatus.  The chamber walls thus are always covered with an uninterrupted liquid layer.          The process can be carried out at standard pressure as well as at excess pressure or at negative gauge pressure.  At negative gauge pressure the system is cooled by evaporation of the solvent.

Abstract: IMPROVED BRAZING PROCESS               ABSTRACT OF THE DISCLOSURE Ferrous parts are bonded together in a copper brazing furnace under suitable temperatures and a furnace atmosphere which, in the absence of parts, is comprised of at least 90% nitrogen, up to 7% combined hydrogen and carbon monoxide with hydrogen being greater than 50% of the total of CO and H2 and having a dew point between approximately -40 to + 10°C.  In the preheat section of a continuous belt furnace or the like, the dew point may range between -20 to +10°C while in the furnace hot zone, the dew point is maintained between approximately -40 to -10°C.  A brazing paste which is preferably a combined copper and 25-75% copper oxide paste is utilized.  With such furnace atmosphere and paste composition, clean part surfaces, which permit superior wetting by molten copper and thus acceptable copper flow and penetration into the joint being bonded, are obtainable.  The furnace atmospheres utilized enable increased life to be obtained from furnace materials such as brick insula-tion, muffles, conveyor belts, and heating elements.                 BACKGROUND OF THE INVENTION The present invention relates to copper brazing and more particularly to the copper brazing of ferrous parts under particular furnace atmospheres which enable improved bonding and increases furnace material life.          Copper brazing is a commonly utilized technique for joining ferrous parts with close fitting joints (less than 0.1 mm wide gaps).

Abstract: ABSTRACT OF THE DISCLOSURE    In the process of recovering minerals, such as hydro-carbons from shallow tar sands, and the like, one method is to create a shallow horizontal fracture within the tar sand.  The size and shape of the perimeter is deter-mined, and one or more secondary boreholes are drilled to the formation inside of the perimeter of the fracture.     Pressurized air is injected into the fracture and the hydrocarbons are ignited.  After a selected period of burning is carried out, the radius to the burn front, surrounding the recovery area, from which the hydrocarbons have been removed, is determined by placing a source of seismic waves at a selected point over the fracture, and a long array of seismic sensors colinear with the source.    The source is energized for different conditions of pressurization in the formation and fracture.  The re-flected seismic waves are converted to electrical signals, which are compared for all sensors.  By comparison of the character and/or energy of the reflections, the geometry of the burn zone can be determined.
