Abstract: An internal exhaust fan (56) propels internal solvent-laden air across a burner (66) where it combusts, causing a heat rise. Heated, combusted air is routed to a recirculating supply air fan (50) which provides for pressurized heated air for air bars (28a-28n, 30a-30n) for drying a web. Heated air in excess of that required to dry the web is vented externally and helps to maintain desired solvent concentration levels. Variable parameters such as fan speed, burner temperatures, air box pressures, exhaust air rate, solvent concentration, supply air flow, supply air temperature and damper vane position are monitored, and the components are actuated to effect a high level of clean up efficiency.

Abstract: Data storage apparatus includes a rigid housing (24), a plurality of data storage disks (18, 20, 22) rotatably mounted in the housing, and a carriage assembly (32 to 50) having a plurality of data trans­ducing heads (40, 46, 50) arranged to co-operate with respective data recording surfaces of the data storage disks. A substantially rigid actuator (52) drives the carriage, and is fixed in the vertical direction to the housing by fastening means (78, 80, 126, 128). A plate (96) mounted integrally to the actuator, and visco-­elastic polymeric layer (108) are interposed between the actuator and the housing. The fastening means are sufficiently flexible to permit limited displacement of the actuator transversely with respect to the housing in response to movement of the carriage. The displacement causes shear strain in the visco-elastic layer whereby the layer tends to absorb and dissipate most of the energy of vibration.

Abstract: A control arrangement including a computer-based controller (30) and bipolar driver (20-28) for bidirectional current control of air core gauge coils (Sx,Sy) by pulse-width-modulation (PWM). The computer-based controller processes input information to determine the desired deflection of the pointer, and looks-up previously stored PWM duty cycle commands for energizing the gauge coils. The bipolar PWM drivers modulate the polarity of the voltage applied to the coils in accordance with the duty cycle commands. Since the drivers are bipolar, a zero strength magnetic field vector is achieved with a duty cycle command of 50 percent. This eliminates discontinuities in the region of zero strength magnetic field vector, and avoids the requirement of generating duty cycles of 0 percent and 100 percent to achieve a full 360 degrees of pointer deflection. Potential discontinuities in the generation of the duty cycles due to input data processing requirements is eliminated by scaling the duty cycles into the range of (DELTA)% to (100 - DELTA)%.

Abstract: In the optical recording element of the invention, alignments of long thin pits inclined in various directions with respect to the track direction are formed on the tracks and information is recorded therein according to the different inclines of the pits, thereby performing higher-density and larger-volume recording without reducing the spacing between each pit and the track pitch. 
     The invention also discloses an optical data retrieval system for use with the above optical recording element, which scans the pit alignments with a laser beam spot, detects the inclines of the pits by obtaining the distribution of the intensity of reflected light which is caused by light diffraction at the pits, and plays back information in accordance with the inclines. Therefore, not only can the substantially same structure as that of a standard type optical data retrieval system be applied to the invention without making any complicated change, but also cross-talk is less likely to be produced in the read out signals.

Abstract: A method and apparatus for performing division is described which first comprises approximating the short reciprocal of the divisor. A reciprocal bias adjustment factor is added to the approximation and the correctly biased short reciprocal is multiplied by a predetermined number of the most significant bits of the dividend and the product is truncated to generate a first quotient digit value. The multiplication takes place in a multiplier array having a rectangular aspect ratio with the long side having a number of bits at least as large as the number of bits required for the divisor. The short side of the multiplier array has a number of bits slightly greater by several guard bits than the number of bits required for a single quotient digit value, which is also determined to be the number of bits in the short reciprocal. The quotient digit value is multiplied by the full divisor and the exact product is subtracted from the dividend to yield an exact partial remainder. The described steps are repeated to serially generate quotient digit values with exact partial remainders with the preceding partial remainder taking the place of the dividend. The quotient digit values are accumulated to yield a complete quotient. The complete quotient is decremented and the remainder recalculated if the final partial remainder is negative, yielding the full precision unique quotient and non-negative remainder pair.

Abstract: The present invention concerns a polymerization catalyst of olefins, said catalyst containing an active chromium compound on an inorganic support. The catalyst in accordance with the invention is prepared by vapourizing a precursor of chromium oxide such as chromyl chloride and allowing the chromium oxide vapour to react with the surface of, e.g., silica gel support material at 160...500°C. A selective binding of the chromium oxide to the support material is achieved by keeping the vapour pressure sufficiently high and the duration of interaction with the support sufficiently long so as to maintain an excess of the chromium compound in relation to the number of available binding sites on the support material. The activity of a catalyst in accordance with the invention even with a very low content of catalytic metal is as high as the activity of a catalyst of an appreciably higher metal content that has been prepared by the methods of the conventional technology.

Abstract: The previously known processes for the preparation of zeolite-analogous gallosilicates require organic structure-directing or structure-stabilising compounds. In most cases those are amines which, apart from the cost factor, may constitute a not insignificant environmental risk. The object is to offer a process for the preparation of gallosilicates having catalytic properties and/or molecular sieve character which is environmentally harmless, expends little energy and is favourable in terms of cost. The process for the preparation of gallosilicates having an Si/Ga atomic ratio of >/= 10 by hydrothermal crystallisation from a reaction batch containing SiO2 and Ga2O3 or hydrated derivatives thereof or alkali metal silicates and alkali metal gallates in an aqueous-alkaline medium is characterised in that the silicone source used is a fine dust containing 86 - 99% by weight of SiO2 and comprising round particles having a particle size of 0.1 - 5  mu m, and the reaction batch is free from organic hydrocarbon compounds or nitrogen compounds. The crystalline gallosilicates are preferably used for the preparation of catalysts and/or adsorbents.
