A method of making a lead-acid battery includes providing continuous lengths of end separator stock, positive plate stock, intermediate separator stock and negative plate stock with optional use of end separators. The separators, positive plates and negative plates are individually severed from the continuous length of stock and sequentially formed into an assembly. The assembly is introduced into...

Insulating metal oxide or nitride films are deposited by RF magnetron sputtering. During sputtering, the atmospheric gas comprises an oxygen or nitride compound gas and an inert gas. The proportion of the inert gas is decreased to 25 atom% or lower. By this sputtering condition, adverse effects caused by the inert gas is suppressed so that the quality of the insulating film is substantially improv...

A turret (22) for a tire building system having two drums (26,49) with drum shafts (30,42) mounted on the turret and adjusted so that the axes of the drums will be offset and parallel providing a compact turret assembly with a minimum shaft length and weight. The offset drum shafts provide for positioning of the drums in operating positions of different heights (50,52) relative to the floor surfac...

This invention is an electrosurgical feedback system (10, 12, 14) for detecting the effects of electrosurgical energy on tissue. The feedback system can include an acoustical detection element (20) that acoustically detects the effects of energy on tissue, and then generates an acoustic stage (50) output signal indicative of these energy effects. A power regulating element (40) in response to the ...

A shaving system has blade(s) (106, 108) and a cap (110) all mounted on a housing. The cap is behind the blades and a guard structure (104) is ahead of them. The guard structure a water-leachable shaving aid composite (116) that is delivered ahead of the blades. In different aspects: 1 The structure also has flexible skin-engaging protrusions (114). The aid is delivered to skin behind the protrusi...

A circuit is described for applying a potential to an electrode of a biosensing test cell, which electrode, when properly inserted in a female connector, is contacted by a pair spaced apart contacts. The circuit includes a source of excitation potential and an operational amplifier having one input connected to the source of excitation potential. A switching circuit is coupled between the operatio...

A single optical fibre (9) transports the excitation energy for the photosynthesis and for the fluorescence and the return signals, and a selective system (33) makes it possible to separate the excitation energy from the return signal.

A method of manufacturing an oil pump rotor of aluminum alloy excellent in resistance to wear, strength at high temperature, and dimensional precision, in which rapidly solidified aluminum alloy powder of high performance containing a dispersion intensifying particle-forming element such as a transition element, solution-treating and age-hardening element, and hard particles is solidly bound throu...
