A drive system for a vertical mast personnel lift uses a pair of rear wheels that are fixed in an axial direction of a base portion of the personnel lift. When an operator input to make a turn is received, DC motors respectively connected to the right and left rear wheels are rotated at a different rate. Neither the front wheels nor the rear wheels are steered during the turning movement. The fron...

L'invention concerne un brûleur à hydrocarbure liquide composé d'un pot à paroi simple, caractérisé par la présence d'un élément catalyseur (1, 1') disposé centralement dans le pot (2).; The liquid hydrocarbon burner contains a catalytic element centrally disposed in the pot. Also claimed, is the treatment process for the preparation of the catalyst.

An intravenous filter device comprises a filter housing having a front side, a back side, a first end, a second end, an inlet and an outlet, the housing containing a hydrophilic filtration media and defining a flow path such that intravenous fluid entering the housing through the inlet passes through the filtration media before passing out of the housing through the outlet. Inlet and outlet tubing...

A rapid exchange stent delivery balloon catheter which allows exchange from a balloon angioplasty catheter to a stent delivery catheter without the need to replace the angioplasty catheter wire guide with an exchange-length wire guide before exchanging the stent delivery catheter for the balloon angioplasty catheter. The stent delivery catheter of the present invention includes a relatively short ...

A button-type battery has an anode, a cathode, and an electrolyte encased with two terminal housing members. The terminal housing members have respective peripheries that are crimped together to form a fluid-tight seal. An insulating gasket is provided between the peripheries to electrically insulate the two terminal housing members. A porous separator physically separates the anode and cathode an...

A coreless transformer with a superconducting primary and secondary winding, wherein both the primary and the secondary winding are divided into a number of sub-windings (P1, P2, ..., S1, S2, ...) and wherein the sub-windings of the primary winding are concentrically interleaved with the sub-windings of the secondary winding forming an interleaved winding package (P1, S1, P2, S2, ...).

MATERIALS of the type usable as raw material for the manufacture of several prod-ucts applicable to such industries as building, automobile accessories, shoes, etc., replacing products such as wood, zinc sheet, fiber cement, plastic and any other rigid or semirigid material, as it contains from 66% to 77% of recycled material obtained by the grinding of 100% of discarded tires, and ground accordin...

The unit has surface exposable extent comprising one or more part sections. A first part (7a) in the coupling device belonging to the one edge part (6d') for a first sheet-shaped part section (6d) works in conjunction with another corresponding second part (7b'). These first and second corresponding parts are orientated at a distance (a) from each other. The first edge part (6e') for the second sh...

A loop polymerisation process or apparatus primarily for vinyl and related monomers in aqueous suspension. The monomers and water are pumped into four rectangular passageway loops (10) operated at a sheer rate above 800 s<-><1> whilst sustaining laminar flow. The polymer is removed from the passageway loops (10) at a T connector (16).
