Abstract: A gear reduction mechanism, particularly for use in an offset final drive unit for vehicular applications, has an input gear meshing directly with the output gear and two additional gear trains between the input and output gears. Three separate load paths therefore exist for the transmission of torque from the input gear to the output gear which means that the face widths of all the gears can be substantially reduced in comparison with a conventional single-mesh arrangement and the overall mechanism can therefore be of reduced width.

Abstract: A wellhead assembly having an inner tubular insertable into an outer tubular. A packoff is provided on an outer surface of the inner tubular for sealing between the inner and outer tubulars. The packoff includes an energizing ring, a U-shaped seal member, and a nut for retaining the seal member against the energizing ring. The seal member includes legs that are spaced apart by interaction with the energizing ring. The outer tubular has a bore wall that is profiled so that when the inner tubular is inserted into the outer tubular, an outer leg of the seal member is spaced radially outward from the bore wall until the inner tubular is landed in the outer tubular. When the inner tubular member is landed, a portion of the bore wall adjacent the outer leg tapers radially inward into sealing contact with the outer leg of the seal member.

Abstract: A swing support mobilization lift includes a jack and a pivotably positionable swing arms, pivotally coupled to the jack, such that the attachment mechanism is capable of being initially displaced in the plane of the jack mechanism during insertion of the lifting device in a narrowly accessible space adjacent to shelving. Then, the swing arms are capable of being pivoted to extend outwardly from the plane of the surface of a jack facing the shelving, such that the shelving may be attached to the swing arms, such as by pins tethered to the jack. In one example, a pair of swing arms disposed on opposite sides of a portion of the shelving sandwich the portion of the shelving and support opposite ends of the pins coupling the swing arms to the shelving.

Abstract: A wireless computerized will call system is provided for filling prescriptions and then locating specific prescriptions that have been filled when the customer arrives to pick up the prescription. The system includes a computer workstation or network, a wireless transmitter, and hanger bags for temporarily storing prescriptions awaiting customer pick up. The hanger bags are equipped with wireless receivers and transducers. When a pharmacy worker commands the computer system to locate a specific prescription, the specific hanger bag containing that prescription receives a wireless signal from the computer system and activates the transducer on the hanger bag to alert the pharmacy worker to the location of the prescription.

Abstract: A valve assembly (2) which is configured to be coupled to a tubing string comprises a housing (8) defining a housing flow path (9) for communicating with the tubing string, and a barrier member (14) located in the housing (8) and configurable between a normally-closed position in which the barrier member (14) restricts access through the housing flow path (9), and an open position in which access is permitted through the housing flow path (9). The valve assembly (2) also comprises a bypass arrangement reconfigurable between an open state in which the bypass arrangement defines a bypass flow path that communicates with the housing flow path (9) on opposite sides of the barrier member (14) to permit fluid to bypass the barrier member and thereby fill the tubing string, and a closed state in which fluid is prevented from bypassing the barrier member to thereby permit pressurization of the tubing string.

Abstract: A high intensity ink solution includes a letdown varnish of about 50% to 58% by weight, a dispersion oil of about 8% to 15% by weight, a pigment about 18% to 25% by weight, a wax compound of about 4% to 10% by weight, and a drier compound of about 1%-3% by weight. A method of producing high intensity color prints includes generating a color space and placing the color space in a CMYK file, generating a color proof, then generating at least four printing plates, and configuring a printer to print specific color densities to accurately match the color proof. Densities of pigments, such as yellow, magenta, cyan, and black are included in the inks, creating color which is perceived more strongly with less dots per area than currently available inks.

Abstract: A scissor mechanism comprises a pair of opposed jaws. The opposed jaws are defined at one end of a rigid member. At least one rigid member is pivotably engaged to a base plate. The base plate is capable of being coupled to a mobilization structure that is capable of being rolled on the ground. For example, the mobilization structure may comprise a jack or a bolt that is capable of raising and lowering the base plate. The jaws provide a strong grip on a portion of the shelving either under the influence of a strong biasing mechanism or by using a lever action to force one or more of the jaws closed onto the portion of the shelving. A bump stop may be adjusted to impinge on another portion of the shelving, which may prevent the shelving from tipping or sliding within the pair of jaws.

Abstract: A drive configuration for a skid steered vehicle comprises a pair of electric motors for propulsion of the vehicle, one each coupled to drive a respective track on a respective side of the vehicle, and one or more electric steer motors coupled through a differential gear mechanism to impose a speed difference between the tracks. An associated control system controls the current to each motor so that substantial contributions to the differential torque to turn the vehicle are made both by the steer motors and by the propulsion motors, in variable proportions preferably as a function of the vehicle speed.

Abstract: A shelving mobilization assembly comprises a support adjustably retained within a channel formed in a pair of castor assemblies, the pair of castor assemblies each include an integrally formed U-shaped cross section between a plurality of castors. The support fits in the channel, and each end of the support and each of the pair of castor assemblies incorporate an interlocking tab and slots arranged such that the interlocking tab engages one of the slots, when the support fits in the channel of each of the pair of castor assemblies. The interlocking tab and corresponding slot adjustably retains the support in the channels of each of the pair of castor assemblies, such that the length between the pair of castor assemblies is defined at a fixed length, when the shelving is supported by the support.

Abstract: A support assembly provides for a method of mobilization that does not require removal of shelving and restocking of items on gondolas and warehouse pallet racking, even if the gondola or pallet racking is too wide for prior art mobilization methods. The support assembly comprises a pair of tubular members capable of engaging fork-like extensions of a hand truck or the like. The hand truck may have caster wheels for mobilization and may have a lifting mechanism for raising and lowering the support assembly by the fork-like extensions, when tongues extending from the tubular members are aligned and matingly engaged at a middle support and outer supports of the gondola. By using a plurality of such lift assemblies engaged along the length of the gondola or gondola run, a row of gondolas may be lifted and mobilized without removing shelving and restocking items on the shelves, even if the gondola is wide and the items stocked on the shelves of the gondola add substantial weight to the gondola.

Abstract: A method of allocating a priority level in an information flow in a data transmission system including receiving a plurality of data packets and allocating a priority level to each data packet is provided with a controller employing such method. The priority level may be determined in accordance with determining a class of loss of the data packet and a class of service for the data packet. The priority level is also a function of the current load of the information flow. It has been established that the choice for each degree of freedom should preferably be made independently and concurrently. The invention, therefore, provides a method for performing such a composite choice.
