Abstract: A protective door jamb system integrally connected to a door frame. The door jamb system of the present invention includes both a door stop and jamb cladding each manufactured from an extruded plastic product such as hollow rigid plastic, cellular plastic, granular filled plastic or fiber filled plastic. The door stop and jamb clad are each designed to attach to a door jamb substrate through compression deflected fingers. The door jamb system of the present invention may also include a weather strip to ensure a weather-tight seal of a door when the door is closed into the frame. The jamb clad of the present invention covers the recessed portion of the door jamb substrate adjacent the jamb to completely cover the substrate and thereby increase both the structural and aesthetic integrity of the frame.

The curb comprises: a frame having side walls and end walls arranged in a generally rectangular shape, and a generally planar portion overlaying a portion of the frame. The planar portion includes a first layer providing structural support, a second layer providing a sound barrier, and a third layer provides a heat energy barrier.

Abstract: A rail car truck side frame for use in a frame brace truck which has stabilizing cross braces extending between the side frames. The side frame has a top compression member and a bottom tension member which are joined by upwardly and outwardly slanted end walls. Each side frame has a pedestal horn spaced from each end wall. There is a bracket assembly at the lower end of each wall for use in mounting a cross brace. Each bracket assembly includes a three-walled channel mounting bracket, with one wall having an opening therein for the mounting of the cross brace. There is a base plate welded to an outboard side of the side frame and having a first portion welded to an upper edge of the channel mounting bracket for providing support therefor. A second portion of the base plate is welded to the side frame pedestal horn. There is a support plate welded to an inboard side of the side frame adjacent its unit guide pocket and welded to the base plate for providing support therefor.

Abstract: The position of a slide valve in a screw compressor in a refrigeration system is controlled using a gaseous medium sourced from two or more sources of such fluid, both of which are in open flow communication with the slide valve actuating piston when the slide valve load solenoid is open. Preferred gas sources are a closed compression pocket in the working chamber of the compressor and the discharge passage downstream of the compressor's working chamber. Gas at sufficiently high pressure is available whenever the compressor is operating to ensure that the compressor will load under all conditions within the compressor's operating envelope.

Abstract: An air inlet and damper arrangement. The arrangement comprises a system housing with an external wall having a fresh air inlet; and an inlet air enclosure located within the system housing adjacent the external wall and arranged about the air inlet. The enclosure has an aperture connecting the interior of the enclosure with the interior of the system housing; and a damper sized to cover the aperture and pivotable within the small enclosure between a position covering the aperture and a position uncovering the aperture.

Abstract: A method of controlling fans in a rooftop air conditioning unit. The method comprises the steps of: determining a measure of compressor operating capacity; calculating an indoor fan speed as a function of that capacity; maintaining a fixed relationship between the indoor fan speed and an outdoor fan speed; and controlling the indoor fan in accordance with the calculated indoor fan speed.

Abstract: A method is disclosed for giving a host CPU direct access to the address space of an embedded microprocessor in a multifunction controller. The data path of the multifunction controller chip is modified to enable this direct access.

Abstract: A process for preparing a catalyst having the following formula:V.sub.a Sb.sub.b M.sub.c O.sub.xwherein M=tin, titanium, lithium, sodium, potassium, molybdenum, tungsten, iron, chromium, cobalt, copper, gallium, niobium, tantalum, tellurium, bismuth, or mixtures thereof,a=0.1 to 5, preferably 0.1 to 3, most preferably 0.1 to 2b=0.1 to 5, preferably 0.1 to 3, most preferably 0.1 to 2c=0.0 to 5, preferably greater than 0 to 5, most preferably 0.01 to 3, andx is a number sufficient to satisfy the valency requirements of the elements,comprising forming an aqueous slurry comprising vanadium and antimony, adding a peptizing agent free of any lithium compounds capable of providing hydroxide ions to said slurry and spray drying said slurry to form an attrition resistant catalyst.

Abstract: A water valve for a sanitary fitting having a valve body containing a metal half, preferably made of brass, which contains a bearing arrangement for a spindle and a plastic half which contains two ceramic packing discs and a driving element, an inlet seal packing opposite one of the ceramic packing discs and water outlet holes. The plastic half is latched into position with the metal half whereby the metal half has a threaded surface on the lower rim of its external surface when assembled.

Abstract: In a sheet set feeder, a shutter mechanism disposed at least in part beneath a hopper for receiving a stack of offset-jogged sheet sets defines an aperture sized to admit individual sets from the stack. The shutter mechanism is driven so that the aperture is moved from beneath one end of the bottommost sheet set--where a retainer supports the next-to-bottommost sheet set--to beneath the other end of the bottommost set. Individual sets fed by the feeder are then carried by a conveyor to a sheet set processor.

Abstract: The object of reducing the assembly costs in the course of producing an adjusted, angularly movable coupling between a pull rod and a plunger rod by means of a constructively further improved link joint, as well as the production costs for the connecting element itself, is attained in that the has a connecting element formed as a one-piece shaped body, which encloses the pull rod and the plunger rod in the manner of a cage and is made of plastic, in which the passages for receiving the pull rod and the plunger rod are arranged in such a way that both rods rest against each other with their external surfaces. The pull rod and the plunger rod are clamped together at their intersecting point by a clamping screw and the plunger rod is additionally clamped with the shaped body in a manner which assures their position.

Abstract: To measure absolute rotations in several directions in space with the aid of interferometers, one interferometer is required for each direction in space. According to the invention, it is proposed to supply a device consisting of several interferometers from a common light source and to switch only the phase modulation impressed on the light rather than the light paths, using time-division multiplexing. The output signals from the interferometers are detected and evaluated with a single detector and evaluating unit.

Abstract: A device and method for measuring a difference frequency having a simple structure and utilizing optogalvanic effect for measuring a difference frequency when carbon dioxide laser light of a single wavelength is varied in frequency by a measuring object. When a part of frequency varied laser light is mixed with an original frequency of laser light by self-mixing in a laser resonator, a strength of the laser light in the resonator is modulated to a difference frequency between the original frequency and the variation frequency. Since a current change in response to strength of light is generated by the optogalvanic effect in the laser resonator, when a frequency of optogalvanic current change is measured, the difference frequency can be measured.
