Abstract: A nested feed forward distortion reduction system, which reduces the distortion from a main amplifier on a main signal path, uses a nested feed forward arrangement for the correction amplifier to reduce the distortion produced from the correction amplifier. In reducing the distortion from the correction amplifier(s) and using progressively higher quality correction amplifier(s), the nested feed forward arrangement produces an improved, more stable representation of the distortion from the main amplifier, thereby alleviating the need for variable gain and/or phase control in producing amplified signal with reduced distortion.

Abstract: In an electron beam apparatus comprising an enclosure in which an electron-emitting device having an electron-emitting region between opposite electrodes is disposed, the electron-emitting device exhibits such a characteristic as that an emission current is uniquely determined with respect to a device voltage. The interior of the enclosure is maintained under an atmosphere effective to prevent structural changes of the electron-emitting device.      An image-forming apparatus comprises an enclosure in which an electron source and an image-forming member are disposed, the electron source comprising the above electron-emitting device. An emission current is stable with a very small change in the amount of electrons emitted, a sharp image is produced with high contrast, and gradation control is easily carried out.

Abstract: An improved contact toaster for heating bagels, muffins and other food items features a housing containing a toasting chamber with an inlet and an outlet. The toasting chamber contains a pair of conveyor belts with a removable platen positioned between them. Two auxiliary heaters are positioned so that they heat both the platen and the conveyor belts. A pair of tensioners engage the conveyor belts so that pathways between the conveyor belts and platen taper inward to a minimum thickness and then expand outward again. As a result, food items moving through the pathways via the conveyor belts are toasted on both surfaces and also absorb heat from both the platen and the conveyor belt surfaces as they are compressed and released. The platen may be diamond shaped to increase the rate and degree of compression and release and removable so that thicker food items may be accommodated. The platen may contain upper and lower heating elements that may be individually controlled to provide greater heat in the region of maximum compression of the food item.

Abstract: A grinding mill liner (18) having inward and outward layers. The outward layer is formed of a relatively soft, shock-absorbent material and the inward layer is formed of a relatively hard, impact and abrasion resistant material. A plurality of magnets (38) are embedded in the inward layer. A pair of pole pieces (44, 46) are positioned on opposed sides of each magnet and embedded in the inward layer. The pole pieces extend above the magnet, protecting it from the impact forces to which the liner is subjected during operation of the grinding mill. The pole pieces also focus the magnetic field forces emanating from the magnet. The magnets are arranged in rows (40, 42, 45), with adjacent poles of adjacent pairs of magnets within each row having alternate polarity; and, with adjacent poles of adjacent pairs of magnets in adjacent pairs of the rows having alternate polarity. The rows are parallel to one another and extend transversely to the direction (48) in which material flows across the liner during operation of the grinding mill. The liner is made up of a number of circumferentially adjoining sections (20). Each section slopes upwardly from a longitudinally extending rearward face (26) toward a longitudinally extending forward face (24). The respective faces of each section extend transversely to the direction in which material flows across the liner. Each section may be a separate tile. The tiles are removably and interlockably attached to the grinding mill's drum to form the liner.
