Abstract: MEMORY PROGRAMMING CONTROL SYSTEM    Abstract of the Disclosure A portable programmer panel incorporating switches, logic circuits and data indicators for storing a wire number program of a ladder diagram in a memory.  A memory board is plugged into the panel.  Selected sets of switches corresponding to fields F1, F2 and F3 are repeatedly set on a decimal basis for three successive instruction words (data) to be multiplexed as a group into memory locations, respectively indicative of the input wire number (F1), the contact number (F2), and the output wire number (F3) for a series contact or the last parallel contact; or the input wire number (F1) and the control coil or other output device number (F3) for an output function; or the input wire number (F1) and the contact number (F2) for a par-allel contact other than the last.  Simultaneously, a switch in the F2 field is set to program the normally-open (N.O.) or normally-closed (N.C.) nature of the contact.  Write-control switches are selectively actuated to enter the data in the memory and distinguish between all but the last one of parallel contacts, series contacts or the last parallel contact, and a control coil or other output function, and to display such data in decimal form and to step to the next memory address.  Switches are incorporated along with a decimal indicator for displaying the memory location being addressed and for "rolling" at high speed or for stepping to locations forward or back and for displaying the data stored in each memory location being tra-versed.

Abstract: A B S T R A C T           A blow molded plastic snow scoop with a wear strip automatically attached to the lip during the blow molding procedure.  The wear strip has two elongated slots, at opposite ends, each extending closely adjacent the respective ends. During the blow molding procedure, ribs of plastic material are extruded from the underside of the leading edge portion, through the slots, and are flattened to provide flanges en-gaging bottom surfaces of the wear strip alongside the slots. During the blow molding procedure, the wear strip is held by positioning pins inserted through the inner ends of the slots. When the pins are withdrawn following the molding procedure, they provide clearance cavities between the inner ends of the ribs and the slots enabling the ribs to shift inwardly along the slots with the cavities receiving the ends of the slots, to compensate for shrinkage of the plastic relative to the wear strip during cooling.

Abstract: ABSTRACT OF THE DISCLOSURE          A method for preconditioning lumps of sugar obtained from humidified and agglomerated caster sugar, before these lumps are oven dried.  The sugar lumps are heated, after moulding, by infra-red heat-ing.  The lumps are heated for a very short, but sufficient, period of time for a cloud of steam-saturated atmosphere to be formed around each lump.  The cloud forms a barrier against the infra-red radiation and prevents the rapid drying of the lump, and ensures that the temperature of the lump, on entering the oven, is higher than the dew point.

Abstract: Applicant:  Saul A. Eller                    No, 321,642 Abstract A low temperature freezing fluid and method are used for year-round wearing away of bitumin deposits, such as those of the Athabaska Tar Sands, by a softening and/or abrasion process.  Relatively small size particles of bitumin and its associated foreign matter are produced which enable separation of bitumin at greater speed, efficiency and thoroughness than present methods.  Water solutions of calcium chloride having a freezing point down to -46°F and a specific gravity greater than that of bitumin are used as the fluid.  Since bitumin deposits vary considerably in physical properties; optimum softening and/or abrasion efficiency and reduced particle size are achieved by either heating the fluid to 212°F to soften or refrigerating it to -46°F to harden the bitumin prior to spraying it at high velocity onto the deposit.  At times, faster rates of softening and/or abrasion and reduced particle size are achieved by incorporating abrasion Particles in the fluid.  The fluid conveys bitumin, foreign matter and abrasion particles to a pool from which they are pumped to on site conditioning and separation tanks. After separation into components, bitumin and fluid are combined and pumped to a refinery wherein they are separated and bitumin upgraded to synthetic crude  oil.  The foreign matter and abrasion Particles are pumped together with fluid to either an on site trailings pond or to recycle equipment. The fluid is recycled.

Abstract: "DISPENSER FOR FLUENT MATERIALS"         ABSTRACT OF THE DISCLOSURE         A hopper is supported above a supporting surface and includes a pair of spaced apart apertures in the base. A metering and dispensing plate is rotatable from one posi-tion to another below the base and includes a pair of spaced apart metering apertures each of which aligns alternatively with the apertures in the base of the hopper as the plate is moved from one position to the other.  When one metering aperture is aligned with one aperture in the base, the other metering aperture is aligned with a dispensing aperture in a base plate below the metering and dispensing plate.  The material from the hopper flows into the aligned metering aperture and the material already in the other metering aper-ture flows out through the dispensing aperture.  The metering apertures are adjustable in volume by rotating the handle ex-tending from the plate which is also used to partially rotate the plate from side to side.  The device is designed for flu-ent materials particularly powdered or granular materials such as sugar, instant coffee or the like.

Abstract: ABSTRACT OF DISCLOSURE:             A load disconnection switch incorporating a quench chamber is described which features a tube-like housing,a telescope-like arrangement of a quench tube and a switch rod guided for relative axial movement within the tube-like housing and releasably connected together by a coupling system the release of which is dependent on relative movement between the quench tube and the housing.             The coupling system comprises at least one blocking device which is displaceably arranged in a respective radial guide in the wall of the quench tube and which engages in a recess provided in the switch rod. A control wall    restricts the radial movement of the blocking device until, after a specified degree of relative movement between the tube-like housing and the coupled  arrangement of quench tube and switch rod the restraint provided by the control wall is lifted and the ensuing relative movement of the quench tube and switch rod results in the current carrying path through the switch rod being interrupted at a spark contact and the heat generated at the spark contact causes the omission of quench gas from an associated quench rod which promptly ex-tinguishes the arc.             The spark contact is conveniently guided in an opening in the wall of the quench tube and a diametrically opposed pressure pad located at the other side of the switch rod ensures contact between the switch rod and the spark contact.
