Abstract: A cube-corner retroreflective sheeting (60) includes an array of cube-corner elements (30) that are defined by three sets of intersecting parallel grooves (45, 46, 47). The cube-corner elements (30) are arranged in the array such that the sheeting (60) glitters when exposed to light. The glitter is in the form of many discrete points of light (68) that tend to blink on and off when viewed by the nacked eye. The array may be configured such that a dihedral angle a varies between adjacent cube faces (31) of adjacent cube-corner elements (30) in each groove in one of the groove sets (45, 46 or 47) and such that base planes (36) are not parallel to each other when the sheeting (60) is laid flat. Preferably, the dihedral angle .alpha. between faces (31) of adjacent cube-corner elements (30) varies in essentially all of the grooves such that the cube-corner elements are randomly tilted throughout the array. The sheeting glitters very well under daytime viewing conditions and also to some extent under nighttime or retroreflective conditions. The glittering effect can enhance the sheeting's conspicuity, and hence highlight a person's presence to give them improved safety and security.

Abstract: The invention concerns a random-check venerator for generating a random number which is preferably represented in binary form, with a particle source, a random-check generating element which acts on particles emitted by the particle source and a detection system which allocates a numerical value, preferably in binary form, to the detection of a panicle emerging from the random-check generating element.      The object of the invention is to ensure that the random-check generator is not susceptible to external interference and delivers high-quality random numbers.      To that end, the particle source can emit at least two particles substantially simultaneously, and one particle can ac~te the detection system in order to ~ect a further particle influenced by the random-check generating element and allocate a numerical value thereto.

Abstract: A universal joint such as a constant velocity (CV) joint in a drive assembly of a front wheel drive vehicle can require a boot to seal the joint from environmental contaminants found on a highway or other vehicle driving surface. Typically, such boots are attached using a clamp, however it has been found that the crimps extending from the clamp can interfere with a vehicle's ABS sensor. The present invention provides a clampless means of attaching the boot to the CV joint, by providing a continuous rib projecting from inner surface of an end of the boot, and a coincident groove on the end of the universal joint, wherein the rib has a means for cooperating with the groove to retain said rib within the groove. It is contemplated that the present invention can be used on other types of universal joint and boot assemblies.

Abstract: A method and apparatus for mechanically reshaping and/or forming textured features in the side wall of metal can bodies (5) in which a can body is mounted on a profiled mandrel (15) and rolled along a second madrel or rail (25), which is also profiled. The tools are made from hard material but either the mandrel carrying the can or the second mandrel or rail is resiliently mounted. This mounting has been found to facilitate control of the depth of the profiled features formed in the can body. In particular, the problem of depth variability which will arise due to expansion of the machine and tooling in normal running conditions, or variability in thicknesses in the can body is avoided. Typically, the can body is clamped between complementary unformed regions on the tools during forming so as to prevent wrinkling or localised thinning of the can side wall.

Abstract: Method and Apparatus for Coupling an ATM Communication Layer to a Plurality of Time-Division Multiplex Communication Terminals A method for coupling an ATM communication layer to a plurality of N mutually time-independent time-division multiplex communication terminals having an overall payload cell rate CR N comprises the steps: generating a control signal sequence with a clock rate corresponding to the overall payload cell rate CR N of the N time-division multiplex communication terminals, whereby the control signals can represent a first or a second status; offering a fixed data pattern; transmitting the ATM cells coming from the ATM communication layer into an ATM cell waiting list; transmitting, on demand, an ATM cell from the ATM waiting list to the requesting time-division multiplex communication terminal when the respectively oldest control signal of the control signal sequence represents the first status, and transmitting the fixed data pattern to the requesting time-division multiplex communication terminal when the oldest control signal of the control signal sequence represents the second status; and deleting the oldest control signal of the control signal sequenc e. The method enables a frictionless coupling of an ATM communication layer having a plurality of mutually independent time-division multiplex communication terminals, whereby variable data rates (burst behavior) of the ATM layer as well as of the time- division multiplex communication terminals can be decoupled from one another and good cell delay variation (CDV) properties can be assured.

Granted: 2006-10-24
Abstract: Use of a histamine H2 mimicking substance for the manufacture of a medicament for the treatment of multiple sclerosis. The histamine H2 mimicking agent is present in an amount which is effective to stimulate production of a cyclic AMP in the body. A phosphodiesterase inhibitor is used in conjunction with the histamine H2 mimicking agent to conserve the cyclic AMP which is thus produced. It is believed that the increased cyclic AMP levels serve to maintain the patient's myeline against self degeneration. The histamine H2 mimicking agent may be histamine phosphate and the phosphodiesterase inhibitor may be caffeine.  The histamine H2 mimicking agent and the phosphodiesterase inhibitor may be mixed in a gel and administered using a transdermal patch.

Abstract: A self-propelled upright vacuum cleaner is provided having a lower portion and an upright handle portion pivotally attached to the floor engaging portion for a pivotal motion between an upright storage position and a pivotal operating position including a transmission operatively connected to a drive wheel and a motor drivingly connected to the transmission for driving the drive wheel in forward and reverse. A clutch engaging member is pivotally mounted to the floor engaging portion adjacent to the transmission for pivotal motion about a pivot axis located generally at a forward portion of the clutch engaging member.    Operably associated with the clutch engaging member is a transverse linking member that reciprocates from a neutral position in first and second directions in response to pivotal motion of a bottom link. The reciprocation of the transverse link selectively moves said clutch engaging member from a neutral position to a forward drive position and a reverse drive position. A finger link member carried on the housing assembly is selectively positioned in a channel formed on the bottom link, relative to the pivotal positioning of the housing assembly.  Pivotal motion of the finger link engages the bottom link member when the housing assembly and handle portion are in an operative inclined position and does not engage the bottom link member when the housing assembly and handle portion are in a storage upright position.
