Abstract: A skate with aligned wheels including a shell which is monolithic with a support for the wheels. The shell is open upwardly and to the rear, and a quarter and a tongue can be slidingly and selectively associated therewith, respectively in a rear position and in an upward region. The quarter has, in a rearward region, a grip handle for the user. The skate also includes a brake which is associable, in a snap-together manner, at a frame which can be associated with the support. A skate with aligned wheels is thus obtained in which it is possible to vary the size number merely by varying the placement of the quarter with respect to the shell; the skate can furthermore be carried easily by the user.

Abstract: This invention is directed to improved treatment for glaucoma. It involves delivering to the eye molecules which increase the outflow of aqueous humor, in conjunction with masking agents. The masking agents reduce the side effects of the therapeuti-cally active molecules by masking the sulfhydryl reactive groups on the molecules. The masking agents can be delivered separate-ly from the molecules, or as adducts of the molecules.

Abstract: A vehicle drying blower assembly includes a series of oscillating centrifugal fans each powered by a blower motor.          Each centrifugal fan includes a circular fan rotated upon a driveshaft and surrounded by a housing having a discharge nozzle; the housing that surrounds the circular fan is supported by a rocker arm for pivotal movement about an axis of rotation coaxial with the circular fan driveshaft.  The rocker arm pivots about a bearing assembly that lies coaxial with the driveshaft of the blower motor.  A drive motor rotates an eccentric crank arm, and link rods coupled between the eccentric crank arm and the housing rocker arms simultaneously oscillate each centrifugal fan to blow moisture from the vehicle.

Abstract: A substantially-universal detector (FIG. 2) of far-end call disconnect-indicative tones detects the foreseeable forms of tone-based signalling of remote-end call disconnect that are likely to be employed anywhere in the world, without reconfiguration orreprogramming for different tones or countries. Implemented in the digital signal processor (DSP) of port circuits of switching systems or adjunct processors, the detector determines parameters of signals carried by the call to the near end and uses them, along with already-present linear predictive coding (LPC) predictor coefficients and indications of energy in the signals, in a multivariate classification of call progress tones from other tones. When presence of any call progress tones is thus detected substantially without interruption for a predetermined minimum time in the received signals, the call is considered to have been disconnected at the far end. In response, a voice messaging system (VMS) adjunct processor deletes any recording of the call progress tones from the end of the recorded message.

Title: Mounting arbor for saw cutting blades
Inventor: CHIUMINATTA EDWARD R
IPC: B27B5/32
Filed: 1993-03-31
Granted: 1999-01-19
Abstract: A mounting for use in mounting rotating cutting blades to the drive shaft of saws is provided. The mounting is an arbor or arbor sleeve having a non-symmetrical outer mounting surface onto which is mounted a cutting blade which contains a similarly configured mounting hole. The arbor or arbor sleeve is designed for use with a cutting blade having a mounting hole which, when viewed from one side of the blade is the same as the outer surface mounting surface, and which viewed from the other side of the blade is not the same. The use of the arbor or arbor sleeve of the present invention with a cutting blade having these characteristics results in the blade being mounted on the saw in only one orientation. The arbor, arbor sleeve, or mounting hole preferably has a generally triangular shape with three sides of unequal length or generally the shape of a trapezium, in order to achieve this blade orientation.

Granted: 2006-03-14
Abstract: The metering device comprises a housing, defining at least one inlet for the material to be metered and at least one outlet for that material, and at least one rotatable ball driven by a shaft, said ball having a transverse bore containing a shuttling ball moving linearly in said bore between two seats and seals against the one or the other seat. The rotatable ball is captured between the seats and seals under pressure against the outlet seat. Such a metering device allows an exact metering, in shot or rapid shot resulting in near continuous flow form, has great simplicity of construction with few working parts such as that it may easily be placed at the dispensing end of a pressure transfer system for liquids and gases and acts as shut off valve between metering use such that it prevents stalled hydrostatic fluid pressure behind the metering device from causing a flow surge ahead of the metering device at start up.

Abstract: A composite article is formed from yarn, comprising high strength fibres and fusible blocking material, and outer fusible material. The yarn is formed into its required shape and placed in a mould.  The outer fusible material is introduced into the mould and its temperature is raised so as to melt the lower-melt temperature blocking fibres of the yarn. Under the action of tem-perature and pressure in the mould, the blocking material fuses so as to fill any interstices between the strength fibres, and the yarn is enclosed within the outer fusible material. The method is useful for forming electrical insulators of high strength glass fi-bre in the form of a loop (4) blocked against flow of moisture by polypropylene and enclosed within non-tracking polyethylene electrically insulating material (6).
