Abstract: Abstract A hydraulic brake system for actuating wheel brake units of an off-highway load hauling vehicle is disclosed and comprises a primary source of system hydraulic pressure, a service brake subsystem and an emergency brake subsystem.          The service brake subsystem controllably communicates actuating pressure to the wheel brake units, and includes wheel brake unit control valves actuable by the vehicle operator to govern the communication of pressure from the primary source to the wheel brake units.  The emergency brake subsystem actuates the wheel brake units in response to sensed system hydraulic pressure levels below a predetermined level.  An emergency hydraulic pressure source supplies hydraulic actuating pressure to brake units in response to brake system pressure levels below the predetermined level.   The vehicle is constructed and arranged so that a power steering system is supplied from the primary hydraulic pressure source.  This enables emergency braking in response to loss of power steering system operating pressure.

A voice response unit is connected to m users' channels, where m is a positive integer greater than 1, for performing the voice output operation for at most m users' channels.  A recognition unit having n (a positive integer smaller than m) input terminals for performing the recognition of at most n users' voice inputs through the input terminals is connected to the user's channels which have requested the voice input operation.  A switch device is disposed between the m users' channels and the input terminals of the recognition unit for connecting at most n users' channels which have requested the voice input operation and selected out of said m users' channels to the n input terminals of the recognition unit in response to a first command of the two kinds of commands given from the computer.  A control unit is responsive to each command from the computer for controlling the voice re-sponse unit, the recognition unit, and the switch device, whereby, in response to a second command of the two kinds of commands given from said computer, the control unit controls the voice response unit to perform the voice output operation for a user's channel, and, in response to the first command, the control unit examines an unoccupied input terminal of the recognition unit. and upon detection of the unoccupied input terminal of the recognition unit, the control unit controls the switch device to connect the user's channel to the unoccupied input terminal of the recognition unit. the voice response unit to perform the voice output operation for the user's channel so as to urge the corresponding user to speak, and the recognition unit to perform recognition operation for the user's channel.

Title: Color change valve structure for rotary head electrostatic spray coating systems
Inventor: CULBERTSON SAMUEL W
IPC: B05B5/04
Filed: 1982-01-26
Granted: 1985-07-02
Abstract: Abstract of the Disclosure A color change valve structure for rotary head electrostatic spray coating systems, of the type to which a rapid rotation is imparted to a rotary spray head and coating material directed through an orifice against the head for discharge from a peripheral edge of the head in a spray, is characterized by coating material and dump valves behind the head i n close proximity with the orifice. The coating material valve controls a flow of coating material from a supply line to the orifice, and the dump valve is operable to establish a passage from the supply line, through the material valve and to a dump outlet. To purge the system of coating material of one color in preparation for spraying material of another, the material valve is closed, the dump valve is opened  and a flow of flushing media is established through the supply line, whereby the flushing media cleanses the supply line and material valve.  Thereafter, the dump valve is closed and the material valve momentarily opened to cleanse the passage between the material valve and orifice, whereupon the system is prepared to spray coating material of another color. The arrangement of the valves enables rapid and thorough flushing of the system, and the close proximity of the material valve to the orifice minimizes the quantity of coating material and flushing media impinged on the head during color change processes.

Title: Process for improving activity of tellurium  containing metal oxide catalysts

Abstract: ABSTRACT OF THE DISCLOSURE         A process for improving the activity of tellurium containing metal oxide catalysts useful as catalysts for oxidation, ammoxidation or oxidative dehydrogenation of organic compounds by heating the catalysts together with a tellurium containing solid to a temperature up to about 900°C in a gaseous atmosphere.  The process can be effec-tively applied not only to deteriorated or spent catalysts, the activity of which has been deteriorated due to use for a long period of time, but also to fresh catalysts.  The tellurium containing solid used as an activity improving agent may be a member selected from the group consisting of (i) tellurium; oxides, hydroxides and organic compounds of tellurium; or those supported on an inert carrier, (ii) tellurium and a compound of at least one member selected from the group consisting of an alkali metal, an alkaline earth metal, lanthanum, cerium, molybdenum, vanadium, niobium, chromium, tungsten, manganese, iron, cobalt, nickel, copper, zinc, cadmium, titanium, boron, aluminum, gallium, germanium, tin, lead, phosphorus, arsenic, anti-mony, bismuth, sulfur and selenium, and preferably molyb-denum, or a mixture of these compounds and/or those sup-ported on an inert carrier, and (iii) tellurium enriched catalysts prepared by adding a Te component or a Te compo-nent and a Mo component to metal oxide catalysts (which are fresh catalysts or deteriorated catalysts).  In a particu-larly preferred embodiment, the process for improving the activity according to the present invention can be carried out by contacting  said  tellurium containing metal oxide catalysts with the tellurium containing solid in a fluidi-zed-bed.    More  preferably,  the  contact  is  carried out during the oxidation, ammoxidation or oxidative dehydroge-nation reaction.

Abstract: ABSTRACT OF THE DISCLOSURE   Apparatus for controlling a salient-pole machine includes a stator current control element to make the stator current iS follow preset desired values i?*.  A field current control element develops from preset desired flux values ?*, from the flux signal output of a flux computer (direction .PHI.L) and from an inductance parameter (the shunt inductance Xq of the machine) a fictitious field current value signal i?*, which represents the field current value which would be used to control a hypothetical nonsalient-pole machine. This signal i?* is modified by a correction factor derived from the product of the longitudinal component of the flux ?d (from the flux computer) and the difference between the reciprocals   of the shunt and series inductances of the machine, to give a field current control signal that accounts for the asymmetry of the salient-pole machine.
