Abstract: A baking oven, in which a cooling air flow is produced in a cooling air guide of the housing, which contains an air inflow duct and an outgoing air duct, by at least one cooling air blower, which flow, in the baking oven door, passes through the intermediate space between the outermost baking oven door sheet and an inner baking oven door sheet, is to be improved with regard to a more uniform cooling effect on the surface of the baking oven door sheet. According to the invention, this is achieved in that the air guide is designed, adapted to the temperature distribution at the outermost baking oven door sheet (7), with varying air throughput over the door width, the greatest air throughput taking place in the central region. …<IMAGE>…

Abstract: 5 n 7  A heating, ventilation and air conditioning (HVAC) system and method for a plurality of mass transit vehicles where each vehicle has at least one independently actuated HVAC unit comprises a command center remote from the plurality of mass transit vehicles, for individually controlling the HVAC unit of each of the plurality of mass transit vehicles. The command center control unit includes a memory unit for storing temperature values desired for each vehicle, and corresponding times of a day and days on which the stored temperature values are desired within each respective vehicle. A sensing device is disposed within each of a plurality of mass transit vehicles. A comparator device, disposed in communication with the plurality of sensing devices and the command center, compares sensed existing temperature levels with stored temperature values for respective ones of the mass transit vehicles and generates control signals being a function of a difference between the sensed temperature and the stored temperature value of a respective vehicle. An operating device, responsive to the generated control signals operates the respective HVAC units of the respective vehicles to reduce the difference between the sensed existing temperature and the stored desired temperature of each respective vehicle.

Abstract: Multi-stage catalytic systems and methods are provided for converting NO x , CO, and hydrocarbons in a mixture, to innocuous products. The systems include first and second stages, each with substrate and catalyst. The mixture is contacted with the first stage for conversion of the major portion of the NO x  and a portion of the CO and hydrocarbons. The output is contacted with the second stage to for conversion of CO and hydrocarbons. In one system, the first stage catalyst consists essentially of rhodium and a zeolite; the second stage catalyst comprises a noble metal including platinum and/or palladium, and a support. The mixture has a mole ratio of reducing to oxidizing agents of at least 0.8. Low ammonia is generated. In another system, the first stage substrate is made of material capable of being heated to at least 150 o C in no more than about 20 seconds, has heating means for doing same, and is at this temperature at least part of the time of contact with the mixture. The first stage catalyst comprises a support and rhodium with optionally platinum and/or palladium. The second stage catalyst comprises a support, and platinum and/or palladium, and optionally rhodium. Most of the rhodium is in the first stage; most of the platinum and/or palladium is in the second stage. At least 70% by volume of the NO x , CO, and hydrocarbons is converted. The weight ratio of Pt and/or Pd:Rh in each system is at least about 15:1.

Abstract: A device (1) for working the ground comprises a frame (2) and a plurality of discs (6). Each disc is rotatably mounted on a lying shaft (5) which is provided on the free end of a pivotable standing shaft (4). In order to prevent jamming of the discs (6) by earth thrown up by adjacent discs (6), each standing shaft (4) is placed on the concave side of its associated disc (6).

Abstract: Described is a method for manufacturing optical fibers. In one embodiment, the method comprises (J) collapsing a silica-based glass tube to make a preform and (K) drawing fiber from the preform. Prior to collapsing the tube, one or more glass layers are formed on the inner surface of the tube by (D) dip-coating the surface with a sol comprising a metal alkoxide dissolved in an alcoholic or aqueous solvent, polymerizing the sol to form a gel, and (E, G, H) drying and sintering the gel. A wide selection of dopant materials, in the form of salts or alkoxides, are readily incorporated by dissolving them in the solvent. In an alternate embodiment, the sol is applied to the outer, rather than the inner, surface of the tube or preform.

Abstract: A deformable mirror device having a two-dimensional array of mirror elements is driven in such a way to reduce the data rate and remove the need for buffer stores. The mirror elements are loaded row-by-row in response to an n bit video signal in 2<n> loading operations. Only n rows are loaded in each loading operation, the other rows remaining in their previous conditions, and the loading continues sequentially down the array. The timing of the loading is such that the duration from loading a given row with a first data bit to loading the same row with the next data bit is proportional to the significance of the first data bit. <IMAGE>
