Abstract: A method for making replacement grouser bars particularly contoured to fit rock worn grouser shoes from blanks cut from inexpensive sheet metal. The blank has a straight lower edge and a curved upper edge such that the bar is thicker at the ends than in the middle. The straight lower edge is easily double beveled and the blank is reverse forged to obtain a finished grouser bar having a straight upper edge and a curved lower edge, the bar still being thicker at the ends than in the middle.
Abstract translation: 一种用于制造更换砂轮的方法，其特别是具有轮廓，以便从廉价的金属板切割的坯料上装配岩石磨损的砂轮。 坯料具有直的下边缘和弯曲的上边缘，使得杆在端部比在中间更厚。 直的下边缘容易双斜面，坯料反向锻造，以获得具有直的上边缘和弯曲的下边缘的成品砂条，杆在端部比中间更厚。

Abstract: This invention relates to an articulated two piece piston designed for reciprocable movement within a combustion chamber of an internal combustion engine. The piston has a crown of high-strength ferrous material that is precision cast net to finished dimensions on all inner and outer surfaces to provide a controlled thickness throughout to ensure mechanical and thermal consistency without any additional machining of the crown. The crown is attached to a separate skirt by the use of a wrist pin, wherein the skirt is made of ferrous or non-ferrous materials by casting or other means.

Abstract: A method for removing impurities (e.g., atomic sulfur) from a reticle for use in photolithography is provided. In one embodiment, a reticle (or photomask) comprising a plate, a first layer over the plate, and a photoresist layer over the first layer is provided. The photoresist layer is removed with a first chemistry comprising a sulfur-containing compound. At least a portion of the first layer is removed with a second chemistry comprising a sulfur-containing etchant, thereby exposing portions of the plate. Removing the photoresist layer and/or at least a portion of the first layer leaves sulfur on at least portions of the reticle. In a cleaning step, the reticle is contacted with one or more excited species of oxygen to remove residual sulfur and other contaminants, such as carbon, sulfur and oxygen-containing species. Methods of embodiments can be used to clean, e.g., binary photomasks, attenuated phase shift masks (APSMs) and high transmission attenuated photomasks.

Abstract: In an embodiment, a bus controller for connecting a device to an Inter-Integrated Circuit (I2C) bus includes fault tolerance features. The I2C bus controller may support fail silent, cyclic redundancy check (CRC), and byte count check operations. The I2C bus controller may include a control unit connected to an I2C core module having a base address. The I2C bus controller may also include a second I2C core module having a base address plus one (BP1). The I2C bus controller may also include a mute timer that countdowns a mute timeout period. This mute timer may be reset upon receiving a fail silent test message sent by a master on the I2C bus in slave mode, or, in the master mode, from itself through the BP1 I2C core module. If the mute timeout period expires, the control unit may disable the I2C bus controller from transmitting on the I2C bus. The control unit may format CRC values and byte count values into messages, and include a byte counter to compare actual bytes received to the expected byte count indicated by a received byte count value.
Abstract translation: 在一个实施例中，用于将设备连接到集成电路（I2C）总线的总线控制器包括容错特征。 I2C总线控制器可以支持无声，循环冗余校验（CRC）和字节计数检查操作。 I2C总线控制器可以包括连接到具有基地址的I2C核心模块的控制单元。 I2C总线控制器还可以包括具有基地址加1（BP1）的第二I2C内核模块。 I2C总线控制器还可以包括静默定时器，其对静音超时周期进行倒计时。 在从站模式下，在I2C总线上接收到由主站发送的故障无声测试消息，或者在主模式下，通过BP1 I2C内核模块，此静音定时器可能会被复位。 如果静音超时时间到期，则控制单元可能会禁止I2C总线控制器在I2C总线上传输。 控制单元可以将CRC值和字节计数值格式化成消息，并且包括一个字节计数器，用于将接收的实际字节与由接收到的字节计数值指示的预期字节计数进行比较。

Abstract: A mechanically actuated sensor indicates the position of a piston within the cylinder of a piston and cylinder assembly. The sensor includes a cam that partially extends into the cylinder chamber for abutting contact with the piston, and a lever arm extending through the cylinder wall for transmitting movement of the cam to a signalling device mounted externally of the cylinder chamber.

Abstract: An electronically controlled, pneumatically actuated pumping system is provided that is especially designed for the precision dispensing of liquids. The system includes a positively actuated inlet valve, and a small-diameter, long-stroke pumping piston that is physically stopped at each end of its stroke. The unique inlet valve and piston enable the system to repetitively dispense metered volumes of fluid at better than one tenth of one percent accuracy. A unique calibration mechanism and detachable dispensing head allow for the rapid disassembly, cleaning, and reassembly of the system. An alternative embodiment of the pumping system incorporates a plurality of dispensing nozzles controlled by a single inlet valve and pumping piston combination. The dispensing unit may be shiftably mounted on a vertically oriented stand, and may be automatically shifted upwardly as fluid is dispensed to minimize splashing and atomizing of the dispensed fluid.

Abstract: A router bit for use with earth-moving equipment such as tractor scrapers, bucket loaders and dozers, composed of two parts, one affixed permanently to the apparatus and the other, which comprises the cutting edge, separable from the former for ease of replacement when worn and ineffective, thus obviating the need for expensive and laborious replacement of the whole router bit assembly. The upper and lower parts are joined by interlocking fingers and secured further by flex pins. The lower part, by means of a bar-like extension affixed to and positioned generally diagonally across the length of either side thereof, is prevented from lateral movement.
