Abstract: ABSTRACT OF THE DISCLOSURE         There is disclosed a method and apparatus for aligning and assembling disk-shaped works having projections on outer peripheries thereof.         A vessel-shaped work is positioned and a plurality of disk-shaped works in a stacked condition are guided to a position on the opening edge of the vessel-shaped work by the work guide means, and then the pin provided for up and down movement on the rotary head is either inserted between adjacent ones of the projections of the disk-shaped works or contacted with and stopped by an upper face of one of the projections of the disk-shaped works.  Also when the pin is stopped by the upper face of the one projection, as the rotary head is rotated, the pin is moved in the circumferential direction of the disk-shaped works so that it is disengaged from the upper face of the one projection and then engaged with an adjacent one of the projections of the disk-shaped work.  Thus, the disk-shaped works are finally rotated in an integral relationship by the pin.  Accordingly, the projections of the disk-shaped works are successively aligned with and fitted into the recessed grooves of the vessel-shaped work beginning with the lowermost one of the disk-shaped works.  In this manner, the plurality of disk-shaped works are finally assembled in an aligned condition to the inside of the vessel-shaped work.

Abstract: Metal particles in powdered form are cleaned of oxides by a method in which the particles are introduced into a plasma stream in the presence of a continuous negative transfer arc.  Ionization of a gas within a plasma gun produces a plasma stream into which the metal particles are introduced at a location within the plasma gun.   A negative transfer arc power source is continuously coupled between the plasma gun and a cathode downstream of the plasma gun and within the plasma stream to remove oxide coatings from the metal particles as they travel along the plasma stream to either a receptacle located downstream from the cathode or to a substrate which forms the cathode and onto which a relatively oxide-free coating is formed by the metal particles. Such methods of oxide removal are particularly effective with highly oxidizable refractory materials such as titanium, tantalum and aluminum.

Abstract: AN INTERFACE BETWEEN A SYSTEM CONTROL UNIT        AND A SERVICE PROCESSING UNIT      OF A DIGITAL COMPUTER                           ABSTRACT      A computer system includes a plurality of central processing units (CPUs), a main memory, a system control unit (SCU) for controlling the transfer of data between the CPUs and the main memory, and a service processing unit (SPU) to interface the computer system with the outside world, such as an operator console.  The method used for interfacing the SPU and SCU includes delivering a BUFFER FULL handshaking signal from the SPU to the SCU in response to the SPU receive buffer having data contained therein and being unavailable to receive data. The SCU responds to the absence of the BUFFER FULL handshaking signal by delivering a TRANSMIT FRAME handshaking signal to the SCU.  A preselected duration of time after delivering the transmit frame, the SCU delivers the actual data in a series of fourteen consecutive clock cycles.  Further, the method for delivering data from the transmit buffer of the SPU to a receive buffer of the SCU includes delivering a BUFFER REQUEST handshaking signal from the SPU to the SCU in order to determine if a buffer is currently available in the SCU.  When a receive buffer grant becomes available in the SCU, a buffer grant handshaking signal is delivered to the SPU.  The SPU responds by delivering the actual data in fourteen consecutive clock cycles.   U.S.:   DIGM:002 FOREIGN:  DIGM:0355

Abstract: A channelized jackfield comprising a housing having therein a linear array of juxtaposed channels wherein respective assemblies of aligned printed circuit boards and connecting slab-like modules are slidably inserted edgewise from the front of the housing. Each of the assemblies includes an inverted L-shaped bracket of dielectric material having a vertical leg latchingly secured to a front edge portion of the printed circuit board and provided with a plurality of spaced notches through which respective terminal lugs extend insulatingly from the printed circuit board and externally of the housing. Also, each of the L-shaped brackets has a leg disposed substantially orthogonal to the vertical leg and carries on its upper surface a guide groove for slidably receiving the connecting module and guiding it into mating engagement with an aligned connector attached to the front edge portion of the printed circuit board. When the assemblies are fully inserted into the juxtaposed channels, the vertical legs of the inverted L-shaped brackets disposed in side-by-side relationship form a portion of a front faceplate for the jackfield.

Granted: 1993-03-16
Abstract: METHOD AND APPARATUS FOR DETERMINING       AUDIENCE VIEWING HABITS A tract of the Disclosure A method and apparatus for determining the channel of a plurality of predetermined channels to which a remotely controlled receiver is tuned.  A viewer transmitter device includes a keyboard for receiving viewer entered selections and a remote trans-mitter which transmits infrared, ultrasonic, radio frequency or other radiated control signals for each of the viewer selections.  A receiver device in a channel detection system receives a signal in the selected transmission medium, and immediately signals a jamming device to broadcast interference which pre-cludes the remotely controlled receiver from identifying and acting upon the transmitted control signal.  The receiver device applies the received signal to a processor device that performs a stored program to determine if the received signal corresponds to a transmitted control signal from the viewer transmitter device and, if so, to identify the channel to which the monitored receiver is to be tuned.  An associated memory device is used for storing the identified channel reception data. The processor device identifies the user selection and either applies a corresponding control signal to a second transmitter device which transmits a control signal of sufficient strength to overcome the inter-ference, or instructs the jamming device to cease the broadcasting of interfering signals.  In either case, the remotely controlled receiver will now receive and implement the viewer selection.  The processor device will periodically broadcast a command to the remotely controlled receiver containing the last identified channel data to ensure that a viewer does not manually adjust the channel being viewed.
