Title: Insulating roll cover
Inventor: HART CHARLES M
IPC: C25B/
Filed: 1991-07-24
Abstract: The cover is free from asbestos and is therefore of more desirable construction for handling and use. 
For the roller cover, at least substantially ceramic fiber is highly compressed, providing a dense and refractory, elevated temperature resistant insulating cover. The cover may itself serve as a load bearing surface; or may provide a foundation or protective media for annular discs or sleeve members made of various, load bearing materials. These load bearing materials may be unable to resist direct contact with the shaft due to thermal shock or the differences in their respective expansion and contraction rates. Where impregnant is utilized with the highly compressed fiber, such will often comprise a colloidal substituent.

Abstract: A method for producing aluminium-containing ferritic stainless steel from a magnesium-contaminated melt is disclosed, such that the steel is suitable for growing oxide whiskers on a surface thereof, so as to cover said surface. The method comprises adding sulphur to the contaminated melt in an amount sufficient to increase the sulphur content to not less than 1.3 times the magnesium content, whereupon the sulphur reacts with the magnesium to render the magnesium inert and thus prevent it from inhibiting oxide whisker growth. The method also preferably comprises an addition of titanium, zirconium or hafnium in amounts sufficient to react with any residual sulphur present in the melt in excess of the amount required for complete stoichiometric reaction with the magnesium present in the melt, thereby mitigating the adverse effect of free sulphur in the steel on oxide adhesion to the steel.

Abstract: Described herein is an improved apparatus and method for aiding computer applications in processing information on a display via keyboard entries. The invention traps keyboard interrupt signals and determines, based on a particular interrupt signal, which key was pressed. If the key was one of the arrow keys, the PgUp or PgDn key, then, depending on which of a plurality of modes the system is currently in, an appropriate action will be taken. Actions include rotation of the current object on the display, movement of an object, zooming in or zooming out. Thus, instead of making the user wade through a plurality of menus and cursor pointings, pressing a single key accomplishes any one of a set of functions.

Inventor: LEBET JEAN-PHILIPPE
IPC: B65D83/14
Filed: 1992-06-10
Abstract: The flux of liquid to be sprayed encounters, before reaching the spraying nozzle (6), a cylindrical part (11) made from an elastically compressible material pierced by a central hole (12). The cross-section of this hole varies as a function of the pressure exerted by the propellent gas on the rear face of this cylindrical part (11). Consequently, when the sprayer is first used, when the pressure of the propellent gas is at a maximum, the cross-section of the passage (12) is the smallest while, towards the end of the life of the apparatus, when the pressure of the gas is at its lowest, this passage has its maximum cross-section. This device provides a self-regulation of the flow rate of the liquid which, consequently, does not vary appreciably over the period of use of the apparatus. <IMAGE>

Abstract: The invention relates to a torque limiting coupling 5 in which a plurality of driving elements 19 of slide-like design distributed circumferentially are arranged displaceably in the coupling hub 10.

Abstract: The invention relates to a drive mechanism (30), particularly for use with a bicycle, of the type having variable diameter drive and driven members (42, 44) connected by an endless belt (50) which engages adjustable segments (46, 48) on the members. Through a control means (32-38) the drive ratio can be adjusted to multiple, discrete settings. Belt wrap is maintained between the belt (50) and the drive and driven members (42, 44) at all settings by two idlers (60, 62) which are independently supported for movement. A locking rail (90) is used to release and secure the segments (44, 46) on the members (42, 44) and a split clutch (64) is used with the driven member (44) for easy rear wheel removal. The mechanism has a lost motion device (112c, 130c) to accommodate forward and rearward pedalling without harming the drive mechanism (30). The drive mechanism (30) is modular in construction so it can be used with frames of varying sizes and the drive mechanism (30) can be quickly removed from or assembled to the bicycle frame when replacement is desired.

Abstract: By essentially eliminating switching losses, a zero-current switching boost converter reduces losses in, and stresses on, the switching elements included within the converter and overcomes the operating frequency barrier exhibited by prior art converters. As a result, a zero-current switching boost converter can be operated at higher converter operating frequencies than a prior art converter with a corresponding improvement in converter power density. A zero-current switching boost switching converter incorporates the natural power sharing mechanism inherent to quantized power converters (note Vinciarelli, U. S. Patent No. 4,648,020), thereby allowing two or more such converters to simultaneously supply power to a common load, with each converter carrying an essentially fixed share of the total load power. 
     Thus, in general, in one aspect, the invention features apparatus for controlling transfer of power from an input current source to an output voltage sink. The apparatus includes a switch for controllably permitting or inhibiting delivery of current from the source to the output sink when the switch is, respectively, off or on; circuit elements defining a characteristic time scale for the time variation of the flow of current in the switch after the switch is turned on; a switch controller for turning the switch on and off at times when the current in the switch is zero, the turn on times being controlled to regulate the ratio of the voltage across the output voltage sink to the average value of voltage across the input source, the ratio being greater than or equal to one, and a unidirectional conducting device poled to permit current flow into the output voltage sink after the switch is opened and to prevent current flow in reverse from the output voltage sink back toward the input source.
