Abstract: An electronic apparatus installation structure has an adapter with rotatably supporting a rotating shaft, and having a bearing part having elongated holes that cause exposure of screw holes and a pin hole of a rotating shaft and a base part. A pin of the rotating shaft is pressed into the pin hole, thereby restraining thrust-direction movement, and also limiting the swinging range of the rotating shaft. Through holes are provided on a radio apparatus at locations corresponding to the screw holes on the rotating shaft, and mounting screws are used to fix the radio apparatus to the bearing part of the adapter.

Abstract: A printing system for printing documents and forms, as needed, in response to user-entered commands, includes a touch screen monitor for displaying information regarding the documents and forms, and user options, and for entry of commands by the user. A memory stores a plurality of documents and forms, the documents and forms being organized into a plurality of libraries, and stores software to control the display of options on the monitor and the interpretation and implementation of commands entered on the monitor. A printer prints documents and forms, and a processor, responsive to the monitor and the memory and communicating therewith, is connected to the printer to control printing of a document or form by the printer upon selection thereof by a user and entry of commands via the touch screen monitor. The memory further stores software to control the display and printing of the documents and forms without the native applications in which the documents and forms were created.

Abstract: The spray nozzle comprises a mixing chamber into which a liquid, forming a first and a second liquid stream, can flow through two inlet openings and which comprises an outlet opening, disposed downstream, for a spray jet. A mixing chamber wall acts as a guide surface for the liquid streams and is shaped at the outlet opening such that the liquid streams meet at an angle at the outlet opening and then form the spray jet. Given an angle of impact of approximately 90°, this spraying process delivers droplets with a high level of kinetic energy and a broad uniform fan-out of the droplet paths. Large areas can therefore be uniformly sprayed with the spray nozzle from a considerable distance.

Abstract: A sanitary fitting including a fitting body with at least one supply channel and at least one discharge channel, at least one supply line which is flow-connected to the supply channel for providing flow connection to a supply network, a drain arm which is flow-connected to the discharge channel, at least one actuating element for adjusting the amount of flow and/or flow temperature, and a fastening element for fastening the fitting body to a base, the fastening element including at least one receiver for frictionally engaging the at least one supply thereby removably securing the fitting body to the base.

Abstract: A method of making and certifying submicron line width calibration standards includes steps of thermal growth of a silicon dioxide film layer on top and vertical side wall surfaces of silicon regions, e.g. strips or mounds, that are formed over a silicon dioxide layer on a silicon substrate, then optically measuring the top film layer thickness, removing the oxide film from the top surface of the silicon regions via a planarization technique that protects the film on the side walls, and finally removing at least some, and in most cases preferably all, of the silicon material to leave just the oxide film that was on the side walls of the former silicon regions as submicron linear features, such as extended isolated lines or connected line segments arranged in a polygon.

Abstract: Oil return from the evaporator to the compressor of a refrigeration chiller is accomplished by routing the suction piping that communicates between the chiller's evaporator and compressor to a location physically below the lubricant-rich pool at the bottom of the evaporator shell and by connecting the lubricant-rich pool to the compressor suction piping at a location where the suction piping is disposed physically below the pool.

Abstract: A cellulosic sheet suitable for use as a security document is provided including a multi-functional transparent secure mark formed therein.

The transparentized portion comprises a transparentizing composition applied to the cellulosic substrate in a predetermined pattern so as to define a graphical image having a relative transparency selected so as to define an area of increased transparency in the substrate. The transparentizing composition comprises a transparentizing agent and a security agent. In one embodiment of the present invention, the transparentized portion includes a printed portion and printed matter defining the printed portion is covered by the transparentizing composition.

Abstract: A rail car truck includes a pair of longitudinally spaced wheelsets, a pair of laterally spaced side frames extending between and supported by the wheelsets and a bolster which extends between the side frames to support a vehicle body. There is a brace connected between the side frames to control relative longitudinal movement therebetween. The brace includes a center clamp assembly located generally intermediate the side frames and generally mid-way between the wheelsets. Each side frame mounts a pair of longitudinally spaced end blocks. There are four struts, each being inclined to the longitudinal axis of the truck and each extending from and being connected to an end block and to the clamp assembly.

Abstract: A reciprocating compressor carries suction valve apparatus on its piston in the form of a sheath. The sheath is retained and guided for motion both in conformance with and relative to the piston on which it is carried so as to accommodate both the flow of suction gas into the cylinder in which the piston-sheath combination is disposed and the compression of such gas therein. Retainers are disposed in the ends of the piston's wrist pin and have end faces disposed in accommodating apertures in the sheath. The configuration of the retainer end faces and the sheath apertures in which they are disposed act to limit and guide the movement of the sheath with respect to the piston.

A method is provided for producing acrylonitrile via propane ammoxidation, comprising introducing propane and ammonia feeds into a fluid bed of a fluid bed reactor, and introducing an oxygen feed into the fluid bed through at least one insulated and jacketed sparger nozzle for reacting with at least one of the propane feed and ammonia feed in the presence of a fluid bed catalyst.

Abstract: A catalytically active material useful to prepare vinyl acetate monomer from ethylene, acetic acid, and an oxygen-containing gas under fluid bed conditions comprises a porous microspheroidal support containing catalytically active palladium crystallites finely dispersed within the support. This catalyst material does not require incorporation of gold to maintain activity and selectivity. A process to produce a vinyl acetate fluid bed catalyst in which catalytically active small palladium crystallites are finely dispersed within the support comprises dispersing selected metal species within the support which have an affinity to palladium to form very fine crystallites of palladium. The affinity metal species may be dispersed by impregnation onto a preformed microspheroidal support or may be intimately incorporated within the support before impregnation with a soluble palladium species.

Abstract: An absorption chiller includes a vertically split absorber section the upper portion of which is a high temperature absorber and the lower portion of which is a low temperature absorber. Weak solution is pumped in parallel from the absorber to both a low temperature generator and a high temperature generator. The low temperature generator is disposed vertically above the high temperature generator. Concentrated solution flows, in parallel, from the low temperature generator to the low temperature absorber and from the high temperature generator to the high temperature absorber.
