Abstract: A vehicle brake includes a compact module having an inlet port connected to the return-to-sump line of a hydraulic operating system on the vehicle. The module includes a path to a filter mounted on the module for filtering the operating system fluid and a poppet valve for bypassing a clogged filter. Passages in the module direct most of the return line fluid through a poppet valve which develops a source of back pressure substantially lower that system operating pressure in a cavity in the module and returns the fluid to an outlet connected to sump. A portion of the fluid in the cavity is communicated via a charge port in the module to a hydrostatic system to replenish leakage and shuttle flow in the hydrostatic system and to prevent cavitation. The source of back pressure in the module is selectively connected to spring-applied, pressure-released brakes through a four-way solenoid valve housed by the module.

Abstract: In order to provide a method of distinguishing natural from synthetic diamond which does not involve costly equipment or long periods to make a measurement, a diamond is irradiated with ultraviolet radiation which is preponderantly of wavelength 225 nm or less, such that substantially only the surface region of the diamond is irradiated. By observing the pattern or luminescence and/or phosphorescence produced by the diamond, an observer can identify the diamond as a natural or synthetic diamond.

Abstract: In order to test whether a diamond has had a layer of synthetic diamond deposited thereon, the surface area of the natural part of the stone is measured by measuring the radiant-flux density of radiation substantially of wavelength 230 nm to 320 nm in an integrating sphere containing the diamond. This is compared to the total surface area of the diamond.

Abstract: This invention relates to imidazopyridine derivatives with the general formula II: ##STR1## These compounds are useful as dual histamine (H.sub.1) and platelet activating factor (PAF) receptor antagonists.

Abstract: In order to examine a gemstone, the stone is irradiated and observed though a filter (5) at a first wavelength which is characteristic of a first class of gemstones. The filter can be rocked from a setting normal to the optical axis to transmit radiation of at least one reference wavelength. The intensities of radiation transmitted at first and reference wavelengths are observed and compared, to classify the gemstone as belonging to the first class or not. In order to detect whether the gemstone is a diamond or diamond simulant, the first wavelength comprises raman emission characteristic of diamond. In order to detect whether the gemstone is definitely natural or not definitely natural, the gemstone is classified as definitely natural if there is a maximum of absorption of radiation at 415.5 nm.

Abstract: An improved networked system having a host computer and multiple printers is provided in which the printers have a bi-directional data communications capability and have at least one memory device capable of storing print data and other types of data files. The host computer can be utilized by a user or a Network Administrator to "read" the contents of each memory device on each printer connected to the network that has the NPAP bi-directional communications capability. The user/Network Administrator can de-fragment data files (e.g., print job files) on a flash RAM memory device, or can format one of the memory devices of a printer (which deletes all of the files stored on that memory device). Furthermore, the user/Network Administrator can transfer a file from the memory of one of the printers on the network to the memory of a second of the printers on the network.

Abstract: A phased array sector scanning ultrasonic system includes a separate receive channel for each respective element in an ultrasonic transducer array. Each receive channel imparts a delay to the echo signal produced by each respective element. The delayed echo signals are summed to form a steered, dynamically focused and dynamically windowed receive beam. A plurality of channels in the receiver are operated by respective receive channel control circuits to apodize the sampled echo signals produced by the transducer array elements with respective selected window function weighting factors as the echo signals are received. Each receive channel control circuit stores a set of window function weighting factors at successive address locations in a memory and includes an addressing circuit for producing an address useable by the memory to provide a desired window function weighting factor for each receive channel from the stored set.

Abstract: An improved printer is provided that improves the response time before jobs are printer by providing a "fast data path" for certain print jobs while also storing on a hard disk all incoming print job data. This "fast data path" is especially useful in situations where the incoming print job lacks an "end of file" code, which could otherwise hold up the processing of either this print job or later print jobs. Once the printer becomes relatively busy, and begins to accumulate a "queue" of print jobs waiting to be processed and printed, the printer will automatically store all of the print job data on the non-volatile memory (e.g., a hard disk) before that same data is sent to the processing circuitry.

Abstract: Alignment during installation of an octant of a tokamak fusion toroidal magnetic takes place at room temperature or at low operating temperature of the magnet. In order to identify the magnetic center of the magnet, a toroidal magnet octant is electrically powered with equal but opposite flowing current and a spatially known probe is utilized to measure the magnetic field of such a powered octant.

Abstract: A system employing ultrasound imaging as a method to localize a patient's tissue volume to be treated prior to applying therapeutic levels of ultrasound energy includes a therapy transducer for producing high-intensity fields that cause necrosis and an imaging transducer for producing high-quality ultrasound images. The therapy transducer is a spheroidal piezoelectric element and the imaging transducer is made up of a plurality of piezoelectric elements mounted in fixed relationship to the therapy transducer. The therapy transducer transmits a beam that is focused at a location in the tissue to be treated. The imaging transducer is then steered to produce successive receive beams which scan the tissue, including the tissue at the focal point of the pulsed therapy transducer. The image of the focal point is then superimposed on an image of the tissue to be treated obtained by B-mode imaging using the imaging transducer to transmit and then receive.

Abstract: An implanted device such as a cochlear implant system includes a housing containing stimulating pulse generating circuitry, and a plurality of electrodes external of the housing and receiving the pulses. Between the pulses, parasitic voltages may build up between the electrodes. In order to control the inrush current due to these parasitic voltages, multi-position switches are provided which selectively couple the electrodes to resistors selected to dissipate the voltages at a preselected maximum current to protect the body organs.

Abstract: Printer (1) has code in memory (5) to interpret one or more page description languages and also stores in memory (5) a table of routines useful in other interpreters and their addresses, as well as code to link partially compiled object code in response to directions in Relocation Tables in the partially compiled code. Data is downloaded to the printer by cable (23) to add another interpreter to the printer. That data is employed by the linking code, which responds to the directions in the Relocation Tables to complete the new interpreter making use of routines already stored in the printer. Since the stored routine table is lengthy, it is compressed. The routine table may be downloaded rather than permanently stored.

Abstract: To process bit maps for full color and other data-intense bit maps for printing, a data processing routine (FIG. 4) determines if a block at data within a page is not in color or is otherwise in a single value. Such data is stored in DRAM (28) in one bit per pel form. Other blocks are stored with eight bit for each pel. A table is then developed defining the contiguous order in a page (FIG. 6). An ASIC (32) then transfers the pel information in order of printing to a video RAM (40) with the eight bits restored for data stored in one bit per pel form. The data applied to that ASIC is decompressed.
