A method for determining the presence of an analyte in a fluid is described along with various components of an apparatus specifically designed to carry out the method. The method involves taking a reflectance reading from one surface of an inert porous matrix impregnated with a reagent that will interact with the analyte to produce a light-absorbing reaction product when the fluid being analyzed ...

A plurality of mobile robots forming part of a travel control system are controlled by a travel control station. The travel control station directs each of the mobile robots to a destination where it performs selected operations. The robot, in response to instructions from the travel control station, searches the route selected by the travel control station and sends the results of the search to t...

A TIRE CONSTRUCTION COMBINING THE TOEGUARD AND INNER LINER A new tire construction and method which makes the toe guard integral with the inner liner is provided. A tire is made using an inner liner that has a width substantially equal to the width of a prior art inner liner plus the width of prior art toe guards minus any overlap. The edges of the inner liner, which wrap around the bead, are rein...

Mo3754 LeA 28,502 PROCESS FOR PRODUCING INTEGRAL SKIN MOLDED FOAMS The use of solutions of zinc carboxylates having 8 to 24 carbon atoms in aliphatic polyamines having molecular weights of from 131 to 500 having a total of 2 or 3 primary, secondary and/or tertiary amine nitrogen atoms as additives for the formation of a compact surface in the production of molded foams having a maximum gross densi...

The tread loosening consists in gripping a zero-degree reinforcing cord which the top of the tyre must comprise in order to apply this method, and in pulling transversely on this cord until it is completely removed from the tyre. Thus, the tread is very easily separated from the carcass of the tyre.

A marking head (1) and device for pressure-transfer of indicia (27) onto the sidewall of a tyre. The head indicia application means comprises a bundle of independent needles (11), free to move with slight friction with respect to each other and driven by a pneumatic piston (3) via a resilient component (4). The marking head (1) is inserted in an automatic indicia applying device. A method is provi...

A control system for controlling both a lean combustion engine equipped with a swirl control valve and an automatic transmission. The control system comprises: a shift detector for detecting that a shift is being executed in the automatic transmission; and a valve control inhibitor for inhibiting the switching the ON/OFF state of the swirl control valve in the course of the shift in the automatic ...

A power-assisted hand brake for motor vehicles, which can be operated in an automatic and power-assisted mode with the aid of an electric motor. If the power assisted brake fails, a conventional parking brake is operated mechanically to apply emergency brakes. The handbrake includes a rotatable spindle with a threaded nut thereon which operates the brake by use of the motor. A carrier plate and pi...

A polycrystalline diamond cutting tool is prepared by employing polycrystalline diamond, which is synthesized on a mirror-finished surface of a base material by a low-pressure vapor phase method, as a tool material. A surface, which has been in contact with the base material, of the polycrystalline diamond layer is utilized as a tool rake face. A flank of the tool is formed by laser processing. Th...

A method for coating a poly(arylene sulfide) polymer surface with a semiconductive layer for static charge dissipation and/or induction shielding comprises laminating a poly(arylene sulfide) substrate against a copper foil sheet at a temperature above the melting point of the PAS substrate, wherein the copper foil sheet has been treated with a silane selected from a specific group. When the lamina...

The adhesion of polyolefin objects, in particular highly oriented polyethylene filaments, to, for instance, polar matrices is improved by oxidizing the surface of the objects and then treating it with a solution of a silane compound, a titanate or a chromium complex.
