Abstract: A G.sub.m -C filter is formed using transconductor elements having first and second degeneration FETs to which first and second control signals are applied. A phase-locked-loop is used to generate the control signals. The control range of the transconductor elements is increased so that the frequency response of the filter can be maintained over increased ranges of various parameters (e.g., supply voltage variations, temperature variations, etc.

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. There is a bracket at the lower end of each end wall for use in mounting a cross brace. The bracket includes first, second and third walls, each integral with the side frame and each extending downwardly from the side frame. The first wall forms the wall for attachment of a cross brace with the second and third walls being perpendicular to the first wall and forming support for the first wall.

Abstract: A data ciphering device that has special application in implementing the Digital European Cordless Telephone (DECT) standard data ciphering algorithm which requires a lengthy procedure of key loading and logic operations during the stages of pre-ciphering and ciphering which require clocks operating at different frequencies. The device performs parallel mode loading of the shift registers, with a ciphering keyword. It also calculates, in a first cycle, during the pre-ciphering, the values of the bits of each shift register that determine the value of the next shift in order to, in a second cycle, effect parallel mode shifting in these registers with a value equal to the sum of the two previous shift values. During the ciphering process, the shifting is done in the registers, in parallel mode and in a single data clock cycle, with a value equivalent to the serial value obtained by the algorithm.

Abstract: An inline packaging machine for folding the flaps of a paper board tray blank around a group of articles loaded on the bottom panel of the tray has provision for emergency shut-down whereby any glue applied to the side flaps of the tray will not set before the tray is completely formed. Moveable side flap folding means is provided at the glue station itself for this purpose. The said emergency flap folding means also serves to support the tray end flaps during gluing. The compression section of the machine that normally applies pressure to the glued flaps includes an inlet portion that is re-configured during emergency shut-down for the same purpose, that is to assure that the flaps are completely folded as the glue sets. The glue station and compression section are mounted on beams that are movable toward and away from one another to accommodate trays of various width.

Abstract: A locating and fastening protrusion extending from a back surface of a vehicle trim strip or molding strip being integrally formed with thermoplastic material of the molding strip. The protrusion is formed by applying a hollow heated die cavity against the thermoplastic back surface of the molding strip. The heated die cavity causes the thermoplastic material to melt and as the die cavity is applied against the molding member, the melted thermoplastic material is forced into the die cavity. The die cavity is then cooled such that the material within the die cavity solidifies. The die cavity is removed such that an integral protrusion is left extending from the molding member.

Abstract: A flush glass window molding for an automotive vehicle has a hollow triangular shaped portion for filling the gap created between an edge of a window panel and the vehicle body panel, a flexible finger located adjacent to a body-side leg of the triangular shaped portion and extending from the apex thereof, and a substantially flat base extending outward at a generally right angle from the apex of the window-side triangular leg. Furthermore, an outside surface of the window molding base is affixed to the inside of the window panel by a pressure sensitive adhesive tape and an inside surface of the base is affixed to a flange of the vehicle body panel by a urethane adhesive bead.

Abstract: Method and apparatus for buffering data packets in a data communication controller environment. In general, the communication controller is interfaceable with a host processor and includes a control unit for accessing a communication medium. Each data packet to be transmitted or received is assigned a unique packet number. Packet number assignment is carried out by a memory management unit which dynamically allocates to each assigned packet number, one or more pages in data packet buffer memory for the storage of the corresponding data packet. If requested storage space is unavailable at the time of request, the memory management unit will allocate a page or pages to an available packet number as the pages become free. Upon issuing the assigned packet number, the physical addresses of the allocated pages of buffer memory storage space are generated in a manner transparent to both the host processor and the control unit.

Abstract: A polymeric composite structure having a polymeric shell layer with a finish-side and a non-finish side and a cross-linked thermosetting polymeric backing layer and method of manufacturing thereof is provided. The cross-linked thermosetting polymeric backing layer is simultaneously molded to conform to the shape of and bonded directly to essentially the entire non-finish side of the polymeric shell layer. The method includes forming the polymeric shell having a finish-side and non-finish side into a suitable shape, placing the shell into a mold, and introducing an uncured blended mixture of unsaturated thermosetting polymeric backing material and cross-linking promoter into the mold to force the backing material to directly coat the non-finish side of the shell.

Abstract: A multipart form and label combination is provided which may be printed in a single pass through a printer. The combination includes a face ply which may be printed with nonvariable and variable indicia, a film ply, and an optional intermediate liner ply. The combination also includes first, second or third removable portions such as, for example, a label, receipt or postcard. In a preferred embodiment, the multipart form and label combination is used as an inspection form.

Abstract: A method of minimizing energy use in a chiller and cooling tower system is disclosed. The method comprises the steps of: determining a measure of chiller efficiency; determining a measure of cooling tower efficiency; determining a measure of the transfer rate of heat energy between the cooling tower and the chiller; calculating a near optimal water temperature as a function of the chiller work efficiency, the cooling tower efficiency and the transfer rate; and operating the cooling tower to provide a conditioned fluid at the temperatures to produce near optimal energy consumption.

At least three of the four panels are of substantially the same longitudinal dimension. The reply envelope is fashioned from the second and third panels upon folding.

Abstract: A calibration target for topographic inspection instruments, operating at sub-micrometer resolution levels, having features on the order of 10 Angstroms in vertical height, an atomic scale distance. The features are formed on a silicon substrate, such as a wafer, by deposition of a thick oxide, such as a typical thermal oxide, over the wafer surface. A pattern of features is patterned and etched to the level of raw silicon at the wafer surface. Areas which have been etched are converted to a thin oxide, which slightly lowers the level of silicon in these areas. All oxide is removed and the slightly lower level of silicon gives rise to features having atomic scale vertical topographic dimensions. Millions of such features are produced simultaneously on a wafer to mimic the effect of haze or micro-roughness on a polished wafer.

Abstract: A process for braking a vehicle and braking system for carrying out that process are disclosed. As braking begins, a start-braking signal is produced. A signal indicating a vehicle deceleration requirement and a signal indicating the actual vehicle deceleration are also produced. At the time the start-braking signal is produced, a control unit sets an initial vehicle declaration signal equal to the signal indicating the actual vehicle deceleration. Thereafter, the control unit actuates at least one brake of the vehicle when the value of the signal indicating the actual vehicle deceleration is different from the sum of the signal indicating the vehicle deceleration requirement and the initial vehicle deceleration signal.
