Abstract: The present invention relates to a notching machine for forming a radial notch into a workpiece, such as the side or end of a tube, pipe or rod. The notching machine includes a workpiece positioning assembly, a hub and spindle assembly, an offset mechanism, a hub drive mechanism and a spindle drive mechanism. The workpiece positioning assembly includes a cross slide table and a vice for gripping and positioning the workpiece into a desired position. The hub and spindle assembly includes a hub that is rotatably mounted on a hub rotation assembly. The hub rotation assembly rotates about a central axis of rotation. The hub carries a spindle and its tool. The hub, spindle and tool share a common axis. This common axis is the axis of rotation of the spindle and tool. The hub, spindle and tool can be aligned in an in-line or offset manner with respect to the central axis. The offset mechanism includes an offset adjustment screw that offsets the common axis of the hub, spindle and tool a desired distance from the central axis. When the hub and spindle are offset and rotated about the central axis, the tool orbits about the central axis through a desired circular path of travel. The radius of the notch cut by the tool is adjusted by adjusting the amount of offset. The hub drive mechanism is hand driven by the machine operator via a hand wheel. The spindle drive mechanism is driven by an electric motor that is directly linked to the spindle. The motor is secured to a frame of the machine via a torque arm.

Abstract: A first embodiment of a flexing base skate (10) includes an upper shoe portion (12) mounted on a base (14). The base includes a forefoot region (20) secured to a forward frame segment (26) carrying forward wheels (18a, 18b). A heel region (24) of the base is secured to a rearward frame segment (28) that carries rearward wheels (18c, 18d). The base defines and flexes at a reduced thickness metatarsal head portion (22), with the skater's heel and the rearward frame segment elevating freely relative to the forward frame segment. A spring (72) incorporated into the base biases the skate to the unflexed configuration. The forward frame section overlaps the rearward frame section for lateral stability. An alternate embodiment provides a rigid full length frame (112) and a flexible base (104) mounted only at the forefoot region (106) to the frame. The base (104) flexes at a metatarsal head portion (108), and is constructed to form an integral spring biasing the base against the frame. The base includes a guide (118) for lateral alignment of the heel region (110) with the frame.

Abstract: A radio communication apparatus in a radio packet communication system constituted by a plurality of radio stations and having a plurality of radio channels is provided. To allow radio stations belonging to different radio links to directly communicate with each other, when a packet as data is to be transmitted, a channel control section (101) inquires of a channel registration section (102) about a radio channel used for reception by a radio station corresponding to the destination address in input transmission data, and a radio channel used for packet transmission is selected. The packet is then transmitted from a transmission/reception section (103) via the selected radio channel. When a packet is to be received, the radio channel in the transmission/reception section (103) is switched to the self-station radio channel stored in a self-station channel storage section (104).

Granted: 2008-09-23
Abstract: La présente concerne une méthode de production de combustibles hydrocarbonés ayant une très faible teneur en soufre. Le procédé requiert l'oxydation catalytique des composés soufrés dans le combustible hydrocarboné, suivi d'une extraction des composés sulfureux oxydés (et polarisés) au moyen d'un solvant polaire. La présente décrit le recours à l'éthanol lors de l'oxydation catalytique. Ainsi, le catalyseur d'oxydation a un double rôle dans le procédé d'oxydation : d'une part, le catalyseur oxyde directement les composés sulfureux, et d'autre part, le catalyseur d'oxydation convertit une petite partie de l'alcool en acide peroxylique correspondant, ce qui contribue également à alimenter le procédé d'oxydation.

Abstract: A plasma arc torch (10) has a secondary gas flow (46) that is extremely large during piercing of a workpiece (36). The secondary flow (46) exits the torch immediately adjacent the transferred plasma arc (34) and is an extremely uniform, swirling flow. A swirl ring (60) is located in the secondary gas flow path (50) at the exit point. A prechamber (58) feeds gas to the swirl ring (60), which is in turn fed through a flow restricting orifice (56). For certain applications the secondary gas (46) is a mixture of an oxidizing gas and a non-oxidizing gas in a flow ratio of oxydizing to non-oxidizing in the range of 2:3 to 9:1. A network (44) of conduits and solenoid valves (SV1-SV17) operated under the control of a central microprocessor (90) regulates the flows of plasma gas (42) and secondary gas (46) and mixes the secondary gas (46). The network (44) includes valued parallel branches (78,80,84,86) that provide a quick charge capability and a set of venting valves (SV11-SV14), also electrically actuated by the microprocessor (90), to provide a quick discharge. In a preferred high-definition embodiment, a nozzle (28) with a cut back outer surface and a large, conical head (28b) allows a metal seal and enhanced cooling.

Abstract: Insoluble, denatured, heat-stable protein particles are used in food and beverage products. The particles are easily dispersible in aqueous solutions and take the form of substantially non-aggregated macro-colloids. In a hydrated state the preferred mean diameter particle size distribution of the insoluble, denatured, heat-stable particles ranges from about 0.1 microns to about 3.0 microns, with less than about 5 percent of the total number of particles exceeding about 3.0 microns in diameter. The majority of the particles are substantially spheroidal in shape and have a substantially smooth, emulsion-like organoleptic character similar to that of high-calorie fats and oils. Additionally, these particles have a degree of protein insolubility of at least about 80%, which provides processing advantages during heat treatment.
