PURPOSE:Electric car control apparatus, which in regenerative running mode, generator brake by resistance at low speed and regenerative brake at high speed are performed.

PURPOSE:To provent liquid leak from a through hole in a shaft by discharging a residual liquid in a bowl up to an escape hole to make pool shallow by the time the rotation of a motor has been stopped after the power of the motor has been cut off to stop the operation of the machine.

Steam, for example, is produced from aqueous brine, by a system that employs preferably hot waste fluid, and nozzle means and rotary separator means generally of a known kind per se. The method steps include transferring the waste heat of combustion source (22) to the brine flowing in heater exchanger coil (23), expanding the hot brine through nozzle means (24) to form a jet of steam and liquid dr...

The bead assemblies (16, 17) are held in accurately spaced relationship against opposite flanged ends of a tube, e.g. by magnetic or vacuum means (Fig.2). Tyre carcass material (26) carried on an expansible former (25) is located within the tube (Fig. 3) and expanded to engage the bead assemblies (16, 17), the projecting ends of the carcass material being turned radially outwardly around the bead ...

An apparatus and a method for driving a guest-host type phase transition liquid crystal in matrix is disclosed in which X and Y electrodes in matrix comprising a guest-host liquid crystal made by adding a pleochroic dye to the cholesteric-nematic phase transition liquid crystal or chiralnematic phase transition liquid crystal are impressed with an X electrode selecting voltage, an X electrode non-...

Polymers containing flame retardant amounts of addition products of alkylhalogen-free esters of (1a) phosphorus acids, (1b) carboxylic acids, or (1c) sulfonic acids and (2) a bicyclic phosphite (1-alkyl-4-phospha-3,5,8-trioxabicyclo-[2,2,2]-octane), said addition products having the following group; WHERE R is lower alkyl C1-C4), preferably C1-C2, an hydroxyalkyl (C1-C4), preferably C2-C3; the ad...

A prewhirl construction for the compressor of a turbocharger. The periphery of the compressor input opening is provided with a plurality of slanted spin vanes which impart a tangential velocity to air entering the compressor. The air is thus provided with a velocity component similar to the compressor's impeller velocity. The input duct to the compressor carries a butterfly valve whose setting con...

An operation mode monitor for a microcomputer in which any one of a plurality of operation modes can be selected in response to an operation mode setting signal generated from an external circuit when reset. The monitor according to the present invention can check whether a predetermined correct operation mode has been selected in the microcomputer in accordance with a checking program and output ...

Steering control means for automatic steering correction in an agricultural machine, especially a harvester for maize or like crops, comprises a change-over switch (7) in an electrical circuit between a regulator (12) and a measurement value transmitter (4) or a feedback transmitter (15), the signal voltages of the two transmitters being summated in the regulator. The switch (7) includes at least ...

A tyre building apparatus has two end drums 3, 3a disposed at respective ends of an intermediate drum 2 comprising a sleeve 39 pneumatically expandable to shape to toroidal form that portion of a tyre carcass which is disposed between the beads. The end drums 3, 3a include bead clamping members 48, 48a and ply turn-up bags 49, 49a, and together with the ends of the sleeve 39 are connected to carri...

An unobtrusive image is applied to paper or other sheet material by means of a charged droplet printer, for example an ink jet printer. The unobtrusive image applied may perform the function usually associated with a watermark in paper, but in contrast to a watermark, may be applied to papers during their production on high speed wide deckle machines or to coated papers. The method is particularly...

An electrical surgical knife device stops supplying an incision current, a coagulation current or a blend current whenever at least two of selection switches are actuated at the same time, said selection switches being provided for selecting the incision current, the coagulation current and the blend current, respectively.
