Abstract: System and method are provided for selecting and accounting for value--added services with a closed system metering device. A scanning device coupled to the closed system postage meter scans information, including recipient address, printed on a mailpiece. From the scanned information or manual selection, a selection of value-added services is made and the closed system metering device performs accounting related to the selected value--added services. The recipient address is combined with other information relating to postage payment for the mailpiece to obtain postal data relating to the mailpiece. The postal data is used to generate an indicium, which includes cryptographic evidencing of postage payment. A graphical representation of the selected value-added services is added to the generated indicium to generate a value-added indicium, which is then printed on the mailpiece.

Title: Operator's station for a lift truck including three position seat assembly
Inventor: HENSHAW ROBERT JOSEPH
IPC: G05G1/30
Filed: 1998-08-26
Granted: 2006-12-19
Abstract: An improved operator's station (70) includes an improved three position seat assembly (90) which allows the operator (200) to stand, perch or sit while maintaining the operator's eyes at essentially the same vertical level (204, 206). The seat assembly includes a back rest (95), a seat (100) that may be raised and lowered, and a movable shelf (105) or perch positioned between the back rest and the seat. In a stand mode of operation, the seat is lowered and the shelf is raised; in a perch mode of operation, the shelf is lowered to provide a partial support for the weight of the operator, and, in a sit mode of operation, the seat is raised for substantially full support of the weight of the operator and the shelf is raised to be flush with the back rest. Two sets of foot pedals (120, 125; 130, 135) are provided in the improved operator's station (70). A first set of pedals (120, 125) is on the floor and includes a brake pedal (120) and a power pedal (125). These pedals are operated when the operator is either standing or perching.      A second set of pedals (130, 135) is raised above the first set of pedals (120, 125) and positioned to be operated when the operator is in the seated position, although the operator may optionally also use one or the other of the raised pedals in either the stand or perch modes of operation, thus providing additional flexibility in operating positions.

Granted: 2005-06-21
Abstract: The present invention provides a grinding cup having a lower grinding section and an upper body section integrally connected to form a grinding cup having top and bottom surfaces. The grinding section is formed from a material capable of grinding the hard materials such as tungsten carbide inserts of button bits etc. A centrally disposed convex recess is formed in the bottom surface having the desired size and profile for the button to be ground. Drive means are provided on or in the upper body section that cooperate with the output shaft of the grinding machine. Retaining means are provided in conjunction with the drive means to releasably secure the grinding cup to the output shaft of the grinding machine during use. The drive means and the upper body section or grinding section of the grinding cup are adapted to optimize the engagement surfaces and points of contact between the grinding cup and rotor or adapter to reduce negative impact on operational stability and rotor wear, as well as other potential associated wear to the grinding apparatus caused by vibration and/or resonance. In addition, substantially reducing vibration and/or resonance will minimize the deterioration of the preferred built-in profile of the cavity in the grinding section. In the preferred design the drive and/or contactsurfaces between gr inding cup and rotor or adapter are substantially harmonized, minimizing operator exposure to sharp and/or protruding features when the grinding cup and rotor have engaged.

Title: System and method for adaptive channel allocation
Inventor: MINTZ YARON
IPC: H04W16/16
Filed: 1998-12-14
Granted: 2007-10-02
Abstract: A telecommunications system and method is disclosed for providing adaptive channel allocation for indoor cellular systems, which utilizes interference measurements on both the down-link channels and the up-link channels. This can be accomplisched by using a Stand Alone Dual Channel Scanner (SADCS) to assist indoor cellular systems in allocating traffic channels on the basis of interference from external systems, which measures both the up-link and the down-link at the same time. A number of SADCSs can be placed at strategically located points in the building to measure interference on a channel by channel basis, and to communicate the results to the indoor base station, which can then allocate traffic channels with high confidence of maintaining a good speech quality.

Title: Thermally triggered safety device to be mounted on pipelines to automatically shut-off the fluid
Inventor: SCHULZE KLAUS
IPC: F16K17/38
Filed: 1999-02-17
Granted: 2007-11-27
Abstract: Inside the casing (1), there are three or more ribs (8) arranged with their longitudinal axes parallel to the closing body's direction of movement when closing so that each rib forms a slide-way for the closing body (5) moving from open into closed position.  Into each of these ribs there is cut a first groove (10) in which is placed a shaped part (11) that supports the closing spring (9). At least the ribs arranged approximately op-posite to the tappet (20) have a second groove whose side facing the seat (7) forms a rest edge (18) on which the control edge may rest when the closing body is in open position. When the fusible soft solder component (21) is melting away, the tappet changes its position in axial direction under the force exercised by the closing spring.  Due to this change of position, the control edge is no longer resting on the rest edge, and the closing body driven by the closing spring switches over into its close position.

Abstract: Low coefficient of thermal expansion (CTE) cermet compositions of this invention generally comprise a hard phase material and a ductile phase formed from a binder alloy, wherein the binder alloy is specially designed having a CTE that is closely matched to the hard phase material. Hard phase materials used to form low CTE compositions of this invention are selected from the group of carbides consisting of W, Ti, Mo, Nb, V, Si, Hf, Ta, and Cr carbides. The binder alloy is formed from a mixture of metals selected from the group consisting of Co, Ni, Fe, W, Mo, Ti, Ta, V, Nb, C, B, Cr, and Mn. In a preferred embodiment, low CTE compositions comprises WC as the hard phase material, and a ductile phase binder alloy formed from a mixture of Fe, Co, and Ni. The so-formed low CTE composition has a coefficient of thermal expansion that is less than that of conventional WC-Co at the same temperature and having the same metal content, thereby providing improved resistance to thermal shock and thermal fatigue related failure.

Abstract: A process for continuously regenerating catalyst particles comprising: passing deactivated catalyst particles downwards in sequence through the first coke-burning zone, second coke-burning zone, oxychlorination zone, and calcination zone in the regenerator, wherein the catalyst particles are contacted with the regeneration gas from the second coke-burning zone, the supplemented dry air, and an inert gas in the first coke-burning zone; introducing an oxygen-containing regeneration gas from the second coke- burning zone into the regenerator, wherein said gas is contacted with the catalyst particles from the first coke burning zone; withdrawing the regeneration gas from the regenerator through the first coke-burning zone and, after the recovery system, recycling it to the second coke-burning zone. The regeneration gas may pass the catalyst bed in either a centrifugal or centripetal way. This process prevents the regeneration gas with a high water content from contacting the catalyst at a high temperature as in the conventional continuous coke-burning processes for regenerating catalyst particles and thereby reduces the decreasing rate of the specific surface area of the catalyst and prolongs its service life.
