Abstract: Abstract of the Disclosure I provide an improved method of transferring a developed latent electrostatic image from the surface of a photoconductor to a carrier sheet adapted to receive the developed image, apparatus for carrying out the method, an improved carrier sheet for use in the method, a method of making the carrier sheet, and apparatus for forming the carrier sheet.  The method comprises providing spacing means between the surface of the photoconductor and the carrier sheet adapted to receive the image, which spacing means extend from the surface of the carrier sheet a distance less than seventy microns and more than the depth of the developed image on the photoconductor. The gap prevents squeezing and deforming of the image and, when a liquid developer is used, prevents the carrier sheet from becoming unduly moistened except by liquid entrained in the charged toner particles forming the developed image.  Transfer is accomplished by impressing a charge on the back of the carrier sheet of a polarity opposite to that of the charged toner particles.  The spacing means may be formed integrally with the carrier sheet or by depositing them on the carrier sheet so as to be interposed between the photoconductor and the carrier sheet which is to bear the image.

Abstract: ABSTRACT            The dry fractionation of oils and fats having a steep dilatation curve (A), i.e. exhibiting a difference in dilatation value at 15°C and 25°C of at least 800 mm3/25 grammes, in practice is difficult. This problem is solved by mixing oils and fats (A) with triglycerides (B) of such nature that the difference in dilatation of the mixture obtained diminishes substantially. The triglycerides (B) have a difference in dilatation values at 15°C and 25°C not exceeding 600 mm3/25 g. The weigit ratio between fats (A) and fats (B) varies between (10-90):(90-10). preferably (20-80):(80-20) and ideally (40-60):(60-40). The process is e.g. particularly attractive for the dry fractionation of palmkernel oil (fat A) in the presence of palm oil (fat B).

Abstract: ABSTRACT OF DISCLOSURE A method and apparatus for cracking heavy hydrocarbons for example petroleum oil or coal tar.  The reactor comprises an outer spherical pressure vessel and an inner vessel within the outer vessel.  The inner vessel has an open bottom end.  The cracking reaction takes place in the inner vessel and the pro-ducts leave through the open bottom end.  me reaction is inhibited in the outer vessel since the contents are maintained at a temperature insufficient to sustain the cracking reaction.  The product is withdrawn, either continuously or inter-mittently via an outlet.  The coke produced may be fluidised in the outer vessel or may he allowed to settle.  The inner vessel may be rotated slowly about its vertical axis and high pressure fluid jets directed at its surface to dislodge coke deposited on the inside and outside wall.  The reactor may be used in a system for the simultaneous distillation and thermal cracking of crude oil.  Feed-stock is fed to a flash-settler having three sections.  Liquid is withdrawn from the first section and fed to a reactor via a heater.  The reaction products are quenched to inhibit cracking by means of a cooling stream prior to their intro-duction to the third section of the flash-settler.  Coke is removed from the third section as a slurry.  Gases flashed off from the feedstock and from the reaction products are fed to a distillation column where they are separated. Liquid from the second section is either removed as product, allowed to overflow into the first section to be recycled, or fed to a reduced pressure column in which heavy gas oil may be removed as a product.  The top product is fed to the distillation column, the bottom product is recycled to the reactor via the heater.

Abstract: METHOD OF PLACING PIPE INTO DEVIATED BOREHOLES                              Abstract A method of pushing pipe (e.g., casing) into a highly deviated borehole.  The lower end of the pipe is plugged and the lower portion of the pipe string is filled with fluids (e.g., air, compressed gasses, petroleum products, water, etc.) which have a lower density than that of the borehole fluid.  This creates a buoyancy effect for the pipe in the deviated portion of the borehole which aids in keeping the pipe from contacting the lower side of the deviated hole.  The pipe can be plugged or capped above the lightened section and filled with heavier fluid to aid in forcing the pipe downward into position.  The plugs and caps are then removed, e.g., drilled out, when the pipe is ready for use.  The fluids are thereby released into the mud slurry.

The julienne cutter has a hub removably engageable with the drive means and a disc-like member secured to the hub.  The disc-like member has an opening extending from a region near the hub to a region near the periphery and there is an elevated portion on the member located behind the opening with respect to the direction of rotation of the disc-like member.          A cutting structure is positioned in the opening for producing multiple closely spaced cuts in food items applied thereto which pass through the opening into the bowl.  In accordance with the present invention, a unitary cutting structure formed of sheet metal having an elongated lower portion and an elevated elongated upper portion are secured to the underside and to the elevated portion of the disc-like member, respectively.  A plurality of relatively closely spaced blades extend upwardly generally perpendicular to and are located between and are integral with the elongated lower and elevated upper portions of the cutting structure.  These blades are sharpened on their leading cutting edges and are formed with the sharpened leading edges of the elevated elongated portion facing forward in the direction of the rotation of the disc for simultaneously produc-ing horizontal and vertical cuts in food items applied thereto for forming clean, crisp, neat julienne strips.  The integral blades in this cutting structure are formed by slitting a sheet of blade metal in a diagonal fashion and then bending the strips formed between the slits perpendicular to the plane of the resulting elongated lower and elevated upper portions of the sheet metal.  Advantageously, this unitary cutting structure in which the blades are integral with the lower and elevated portions secured to the disc member provides a simple, rugged structure which can withstand the forces applied thereto through repeated uses and which produces clean, crisp, neat and relatively uniform julienne strips and similar types of strips.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and optical arithmetic apparatus for converting residue numbers into positionally notated numbers utilize linear periodic structures which can be shifted relative to one another, each linear periodic structure being allocated to a prime number module of those prime number modules which are utilized in the residue representation of a decimal number, with the duration of the period for a structure being proportional to the module allocated thereto.  The structures may be structures for generating standing light waves.  The shift of the phase positions of the light waves is undertaken by respective phase modulators with the waves being shifted out of an original phase position in accord with the allocated residue module or the sum of the modules.  The decoded result is obtained by noting the values occurring at positions where the structures coincided before shifting by means of the phase modulators and which coincide after the shift.
