Title: Method of making a hollow working tool

IPC: B22D25/00
Filed: 1986-04-30
Abstract: A method of making a hollow working tool for the treatment of a predetermined shaped portion of a workpiece, and particularly a hollow inductor for use in inductive heat treatment of a workpiece. The method comprises casting a solid blank (B) which has an external profile which corresponds with the required external profile of the inductor (1) e.g. the tooth space (11) between two adjacent gear teeth - (10), the blank being made of an electrically conductive material having a relatively low melting point and and being (a) cast in a shape having an external profile which is undersized in a predetermined manner relative to the required external profile of the inductor or (b) subsequently reduced in size so as to provide this undersized external profile. A thick metallic coating is applied to the undersized external profile of the blank so as to provide a composite structure having an external profile which corresponds with the required external profile of the inductor (or which is worked subsequently to provide this profile). 
     the coating is made of a material having a significantly higher melting point than that of the cast material forming the blank, and is of sufficient thickness to provide a rigiod structure upon subsequent removal, by heating, of the material forming the cast blank.

Abstract: @ A drum servo circuit for a magnetic recording and/or reproducing apparatus uses a 30 Hz or 60 Hz oscillator circuit (counter) (31), and a trapezoidal wave signal (or a sampling pulse signal) is produced by selectively using threshold values set in the oscillator circuit depending on the play mode, so as to eliminate the need to externally couple a plurality of variable resistors to a monostable multivibrator. A drum motor (21) which drives a rotary drum is controlled responsive to a phase error signal which is obtained by comparing the phase of the trapezoidal wave signal (or the sampling pulse signal) and the phase of a rotation detection signal which is obtained by detecting the rotation of the drum motor.

Abstract: Method and apparatus for recovering sulfur from an aqueous slurry. The slurry is passed downwardly through a shell-and-tube heat exchanger having verti­cally arranged tubes, wherein it is heated sufficiently to melt the sulfur. The liquid mixture leaving the heat exchanger is discharged into a first separation zone, in which a phase separation between the lighter aqueous phase and the denser liquid sulfur occurs. The upper aqueous phase is then transported to an intermediate point in the height of a vertically elongated second separation zone, while the molten sulfur is transported from the lower end of the first separation zone to a point adjacent the lower end of said second separation zone, in which an interface between the phases is main­tained at a point below the entry point of the aqueous liquid phase into the second separation zone. The aqueous liquid is discharged from the top of the second separation zone, while molten sulfur is discharged from the bottom of said zone.

Abstract: A bus controller, operable to grant access to a bus structure for communication between a number of individual processor modules interconnected by he bus to form a multiprocessor system, is also operable to determine the number of processors connected to the bus. The bus controller, in round- robin fashion, sequentially grants each processor access to the bus by commanding the processor to send data. The processor responds either by send- ng data in synchronism with a data clock supplied by the bus controller or, if no data is to be sent, responds with a no acknowledgment (NAK) signal. nitially, and periodically, the bus controller checks to determine the number of processors by, beginning with the highest identifying numbered processor, sending to that processor a send command, and looking for a response either in the form of data being sent or a NAK signal. If neither of these responses is received, the bus controller will transmit a send command to the next highest identifying numbered processor in order, continuing this process until a response is received. At that time, the identifying number of the processor is saved, and thereafter only that number of processors are in the bus controller's repertoire, until the next check is made.
