摘要： A bottom feeder for copy paper feeding has means for imparting a curvature to the sheets, the curvature being in the direction the sheets will be withdrawn. The curvature provides transverse rigidity to permit lifting weight of stack off the bottom sheet. This facilitates withdrawing the sheets one at a time from the bottom of the stack.A curved paper tray imparts a curvature to the paper. A pair of holding clamps are provided, one on either side of the stack of paper, which are partially withdrawn from the sides of the paper stack so that paper may be added to the stack. When sheets are to be fed, the clamps which comprise a pair of plates having a friction material on the paper facing side thereof are moved in to engage the sides of the stack of paper. An arrangement is provided to thereafter lower the paper tray slightly from the bottom of the stack, or lift the clamps and the curved paper stack. In either event, the pressure of the stack weight is now removed from the bottom sheet.A vacuum type feed belt which passes under the stack of paper can now pick off one sheet at a time without the sheets being restrained by friction against the paper tray or created between the tray and the stack of paper.The friction material on the holding plates in a preferred embodiment comprises bristles angled upward away from the paper tray to retain the stack lifted from the paper tray while allowing relatively easy withdrawal of each sheet. A stack-height sensor, preferably a switch on the face of one of the plates, senses the condition where, as the height of the stack diminishes, the pressure of the holding clamp plates may be slightly reduced to avoid binding of the paper. Timing means, which in the disclosed embodiment comprise cams riding on a common shaft, are provided to coordinate the movement of the clamps toward and away from the sides of the stack with the movement of the paper tray away from the bottom of the stack of paper.

摘要： A document feeder is disclosed wherein a document stack is bent or curved when it rests on a fixed curved stackholding tray. A stack of paper becomes rigid when curved, and therefore, capable of being raised by applying an upward force along the curved edge on each end of the stack provided by a pair of curved lifting blades which move horizontally relative to the ends of the stack to move in and out underneath the edges of the stack, and thereafter move vertically to lift the entire stack out of the path of the returning copy. The document to be copied may be lifted off the top of the document stack either before or after the lifting action of the blades. A vacuum belt type arrangement is provided for moving successive documents from the top of the stack. The document loops through the machine, and returns at a lower level, aligned with an opening beneath the bottom of the stack. A levered plate is provided at the trailing lateral edge of the stack to be sure that the edges of the stack are lifted out of the return paper document path. Moving the belts running beneath the stack carry the returning document into alignment under the stacks; a metal plate running horizontally or laterally along the edge of the stack perpendicular and very close to the belts acts as a stop to stop the returning document in alignment with the document stack being fed. Once the document is returned, the lifting blades move vertically downward, and laterally outward, resting the remainder of the document stack on the returned document and making it a part of the stack.

摘要： A sheet feeder is disclosed having a cartridge mounted adjacent the stack of paper providing an exposed line of adhesive strip. The adhesive should be a temporary adhesive which when removed leaves no residue or damage on the sheet to which it was temporarily bonded. The cartridge is landed on the top sheet of paper adjacent the leading edge of the sheet, and the cartridge is then rotated away from the direction in which the sheet is to be fed while maintaining a minimum amount of pressure on the top of the stack. This effectively bonds the gummed strip on the cartridge to the edge of the top sheet of paper; and the motion away from the feeding direction lifts the top edge of the sheet from the edge of the sheet below, which now forms the top of the stack. The sheet below, also to be called the second sheet, remains in place because of the combination of downward pressure against the second sheet near its leading edge created by the cartridge, together with the beam strength of the paper which tends to cause the sheet to continue to lie flat. The cartridge can now be moved in the feeding direction, presenting the sheet of paper to an entry path to the copying machine.
摘要翻译：公开了一种纸张馈送器，其具有安装在纸堆附近的盒，提供暴露的粘合带条。粘合剂应该是临时粘合剂，当被除去时，其暂时粘合的片材上没有残留物或损坏。墨盒在纸张的前缘附近落在纸张的顶部纸上，然后将墨盒旋转远离纸张的供给方向，同时保持堆叠顶部的最小压力。这有效地将墨盒上的胶带粘贴到顶部纸张的边缘; 并且远离进给方向的运动将片材的顶部边缘从下面的片材的边缘提起，该片材现在形成堆叠的顶部。下面的片材也被称为第二片材，由于与由盒子产生的前缘附近的第二片材的向下压力的组合以及纸张的光束强度与纸张的光束强度的组合保持在适当位置继续平躺。墨盒现在可以沿进纸方向移动，将纸张呈现到复印机的入口路径。

摘要： An electrophotographic copying apparatus in which heat fusible toner is transferred from its photoconductive drum to one surface of the ultimate copy sheet being made is disclosed herein along with a particular technique for fusing the transferred toner onto the sheet just mentioned. This fusing technique utilizes a fusing roller having an outermost circumferential surface and containing inwardly of this surface a material which undergoes a phase change at approximately the fusing temperature of the toner. The roller is heated to at least the toner fusing temperature in order to cause the material to undergo an endothermic phase change and thereby serve as a means of storing heat, and thereafter, the roller is caused to engage successive copy sheets carrying transferred toner sufficient to cause the heat from the roller to use the toner thereon.

摘要： A crossmixing method for ensuring adequate mixing of a developer in an electrostatic printing machine. The method utilizes a screw conveyor having a left-hand thread on one portion thereof and a right-hand thread on another portion thereof, to move developer material from the end of the screw conveyor toward the middle thereof. Material is discharged from the screw conveyor into the sump of the machine in a direction generally toward the opposite end of the screw conveyor from where it originated. Developer material is moved from the sump upwardly onto a plate assembly which includes angled separators for guiding the developer particles and shifting them in opposite lengthwise senses on opposite halves of the plate assembly. From the plate assembly, the developer material moves in a curtain downwardly into the sump.

摘要： A gasifier for converting solid organic fuels to combustible gas includes a cylindrical body having insulated side walls and a gas outlet port near its base. Affixed to the top of the cylindrical tank is a conical-shaped fuel feed hopper and beneath it and within the interior of the tank is an inverted truncated one. Positioned beneath the throat of the inverted cone is a pyramidal-shaped grate for supporting the combusting solid fuel during the inversion process. Positioned beneath the grate are a series of baffles. Combustion air is drawn in through the upper portion of the tank near the base of the frusto-conical feed hopper by the action of a motor-driven fan coupled to the gasifier's outlet port. The down draft gas flow reduces noxious fumes and pollutants while the baffles, by increasing the fluid velocity of the gases, tends to make the unit self-cleaning. The design of the hearth cone and grate also eliminates bridging of the fuel during the gasification process.
