Patent number: 5384976Abstract: A pile weatherstrip has an elongate base strip carrying a pile of thermoplastic fibres. A zone is formed adjacent the base of the fibres fused together and compressed to reduce their width. This provides a comparatively smooth and narrow zone that does not snag on the flanges of a carrier as the pile weatherstrip is inserted into the carrier. The zone can be produced by passing the weatherstrip through a nip formed by heated rollers. In an alternative embodiment, the fibres are fused together for their whole height. This has the additional advantage of providing an air-impervious barrier.Type: GrantFiled: April 5, 1993Date of Patent: January 31, 1995Assignee: Linear LimitedInventor: Alfred B. Hall

Patent number: 5385014Abstract: The present invention provides a valve for preventing contamination of a fuel management system connected to a pneumatic sense line by closing communication of compressed air from a scroll of the engine through a passageway in the valve to the pneumatic circuitry of the fuel management system. A detent is located on one side of the valve for receiving a raised surface on the knob of the valve and for holding the valve in the open position. A pair of stops on a camming surface separately engage a second pin on the valve to stop a handle of the valve from rotating past the selected open or closed position. The valve has all metal surfaces isolated so it may withstand vibrations. A method of washing a compressor of an aircraft engine is disclosed.Type: GrantFiled: September 27, 1993Date of Patent: January 31, 1995Assignee: Aeronautical Accessories, Inc.Inventor: Richard T. Rathbun

Patent number: 5385016Abstract: A system and method of controls air/fuel ratio of an engine having exhaust manifolds from first and second cylinder banks coupled to a single catalytic converter. Fuel delivered to the cylinders of the first cylinder bank and the second cylinder bank are adjusted in response to respective first and second upstream exhaust gas oxygen sensors coupled to the first and second exhaust manifolds, and a downstream exhaust gas oxygen sensor positioned downstream of the converter. An inferred signal is read from a table having the first and second sensors as their inputs. This inferred signal is an inference of an output from a hypothetical exhaust gas oxygen sensor exposed to a hypothetical blended mixture of exhaust gases from the first and second exhaust manifolds. Converter efficiency is indicated by a ratio of a count in transitions between output states of the downstream sensor to a count in transitions between output states of the inferred signal.Type: GrantFiled: December 27, 1993Date of Patent: January 31, 1995Assignee: Ford Motor CompanyInventors: Glenn A. Zimlich, Daniel V. Orzel, Tri T. Truong

Patent number: 5385017Abstract: A catalyst heating control apparatus includes a catalytic converter arranged in an exhaust passage of an internal combustion engine, a heating part for heating a catalyst of the catalytic converter after the engine has started operating so as to promote a catalytic conversion of exhaust gas from the engine, a detecting part for sensing a temperature of engine coolant of the engine and a calculating part for determining a releasing condition based on an engine temperature sensed by the detecting part at the start of the engine operation. The heating of the catalyst of the catalytic converter is stopped when the releasing condition is satisfied. A stopping part stops the heating part from heating the catalyst of the catalytic converter when an operating condition of the engine satisfies the releasing condition.Type: GrantFiled: October 8, 1993Date of Patent: January 31, 1995Assignee: Toyota Jidosha Kabushiki KaishaInventor: Kenichi Harada

Patent number: 5385020Abstract: A heating and cooling apparatus having a first gas conduit, a second gas conduit and at least one thermoelectric module. In a first embodiment, structure is provided to introduce moisture into the second gas conduit, upstream of that conduit's association with the thermoelectric module. The introduction of the moisture into the gas within the second gas conduit functions to decrease the temperature between the temperature of the gas in the first conduit and the temperature of the gas in the second conduit, thereby optimizing the operation of the thermoelectric module. In a second embodiment a plurality of thermoelectric modules are arranged in an array and positioned between the gas conduits and associated therewith. The power supplied to each of the thermoelectric modules is adjusted to correspond to an optimum power input calculated for each thermoelectric module respectively.Type: GrantFiled: January 25, 1994Date of Patent: January 31, 1995Assignee: Pneumo Abex CorporationInventors: Scott B.

Patent number: 5385022Abstract: A method which removes the limitations existing on the cooling capability of ordinary TE coolers provides for thermally connecting in parallel a hierarchy of central and auxiliary thermoelectric couples to provide deep cooling of the central thermoelectric couple to temperatures below 100 degrees Kelvin, and as low as 70 degrees Kelvin or lower. These basic deep TE cooling units may serve as constituent components for the construction of one-stage deep TE modules which are capable of relatively high pumping capacity at very low temperatures. The present invention makes deep TE cooling possible with existing thermoelectric materials, and existing high volume semiconductor manufacturing techniques can be adapted for production of the present invention, so that solid state deep TE cooling becomes available for a wide variety of applications, including deep cooling of solid state electronics.Type: GrantFiled: September 9, 1993Date of Patent: January 31, 1995Inventor: Levy Kornblit

Patent number: 5385023Abstract: A dry ice pelletizer includes a ram structure that eliminates the need for piston rings to form the pellets thereby eliminating contamination of the pellets from piston ring wear products and piston/cylinder lubricants. The ram structure is pulled down into compression contact with dry ice snow formed in a snow chamber by a pair of hydraulic actuators coupled to a cross-head. The physical separation of the ram and the actuators further eliminates the source of contamination from hydraulic actuator fluid.Type: GrantFiled: July 28, 1993Date of Patent: January 31, 1995Inventors: Arthur A.
