Abstract: ABSTRACT Impregnated wood and other impregnated cellulose based materials are dried in high boiling drying media, drying oil, under reduced pressure.  During the treatment the material is withdrawn from direct contact with the drying medium at several times.  The absorption of oil in the materials can thereby be controlled.  Materials of different qualities and origins can be dried with good results and the oil absorption does not have to be made dependent on the penetration depth of the impregnating solution.  An autoclave for drying of wood according to this process preferably has a rectangular inner cross section and is provided with means for lifting and lowering the materials, preferably a lifting table or frame.

Abstract: S P E C I F I C A T I O N                 FRENCH FRY CUTTER FOR FOOD PROCESSORS                   Inventor : Koichiro Shibata ABSTRACT OF THE DISCLOSURE           A French fry rotary cutter tool is provided for use in food processors of the type having a working bowl with tool drive means extending into the bowl for rotating the tool in the bowl and a removable cover for closing the bowl when in use with a feed passageway for introducing food material into the bowl.  The French fry 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 multiply closely, spaced elongated rectangular shaped cuts in food items such as potatoes, applied there-to, with the resulting French fry cut food passing through the opening into the bowl.  In accordance with the present inven-tion, a cutting structure is formed of a continuous strip of blade metal bent into a rectangular-wave shape (rectangular zig-zag shape) and having alternating, spaced flat, lower portions and spaced, flat, upper portions which are secured, respectively, to the underside and to the elevated portion of the disc-like member.  This bent blade strip thus advantageously defines a plurality of spaced, upright, parallel blades extending upwardly, generally perpendicular to, and located between and integral with the spaced flat lower and spaced, flat, upper portions of the bent blade strip.  Consequently, the cutting structure has a square-wave appearance as viewed forwardly or rearwardly.  The leading, cutting edge of the blade strip is advantageously sharpened before it is bent into shape, and therefore each of the upright blades and each of the flat upper portions have sharp leading edges facing forward in the direction of the rotation of the disc for simultaneously pro-ducing horizontal and vertical cutting in food items applied thereto for forming clean, crisp, neat, elongated, rectangular shaped French fry cuts.  The cutting structure is ruggedized by a flat plate-like blade element with a sharpened leading edge which is mounted on and projects forward from the elevated platform portion of the disc-like member.  In addition, the trailing edges of the spaced upper and lower portions of the square-wave-shaped, bent blade strip have rearwardly extending integral tongues which are respectively secured to said flat plate-like element and to integral rearwardly extending tongues of said disc-like member.

Abstract: ABSTRACT A gun barrel chamber is disclosed in which an ammunition unit can be moved in its longitudinal direction up to the bore of the barrel for ramming the driving band of the ammunition unit into position in the rifle origin of the bore of the barrel.  The barrel chamber comprises an extended rear cavity and a front cavity, connected directly to the front end of the rear cavity.  The front cavity is substantially cylindrical or slightly conical, expanding backwards. The front cavity has such a diameter and length with respect to guiding means on the ammunition unit that when the ammunition unit moves along the bottom of the chamber it is "guided up" before the guiding means enters into the bore of the barrel and that said "guiding up" means that the longitudinal axis of the ammunition unit substantially coincides with the bore axis.  In one preferred embodiment of the invention the bore of the barrel from the rifle origin and forwards for a distance corresponding to the distance between the front guiding means and the driving band of the ammunition unit is slightly widened.

Abstract: ABSTRACT:       In a data processing system a control device is described for an intermediate memory during a bulk data transport between two data devices.  The first data device addresses a number of descriptor signals (D).  Each des-criptor signal indicates another descriptor signal, so that a sequence is formed which is cyclically coupled end-around.  The descriptor signals indicate either a memory section or a branch to a remote address in the memory.         The memory sections used may thus be distributed through-out the memory.  Additional descriptor signals indicate, in a direct or indirect manner. a descriptor signal of the sequence for each of the two data devices.  A handshake by way of signal bits is present at the level of the memory sections.
