Patent EP-0062697-A2 (EP)
Inventor: MARTINI IACOPO DR ING
IPC: F27B9/20
Filed: 1981-10-26
Abstract: In the walking beam furnaces, in order to heat metallurgical materials such as billets, bars and the like, having different temperatures of introduction into the furnace and/or different cross sections, so as to discharge materials at uniform temperatures from the furance, said materials are selected according to their temperature and/or cross section, and are introduced into the furnace through a plurality of side inlet doors while said materials are conveyed along the furnace by means of an external side conveyor, and/or they are discharged from the furnace through a plurality of side outlet doors and are then advanced outside along the furnace by means of an external side conveyor. The external side conveyor can be formed by a walking beam conveyor, timed with the internal walking beam conveyor as to the length and rate of steps, and/or timed in relation therewith so that at each occupied position on the external walking beam conveyor always corresponds an unoccupied position on the internal walking beam conveyor, and vice versa. The external conveyor can be enclosed in a chamber which, if desired, is insulated and is associated with heating means such as the exhaust gases discharged from the furnace.

Abstract: A hot sprue assembly is provided for controlling flow of molten material into the mold cavity of an injection molding machine. The hot sprue assembly is particularly designed for use with an injection molding machine for molding centrally apertured record discs, such as video information discs. The hot sprue assembly includes a hot sprue bushing cooperating with a generally conically-shaped dispersion head to define an open an relatively narrow annular gate through which molten material is injected into the mold cavity, and a central die plug within the mold .avity for cooperating with the dispersion head to mold a central aperture into the disc. Valving of the molten material through the gate is achieved by heating the sprue assembly to create a temperature differential which, during solidification of the material within the mold cavity, permits the material within the mold cavity to solidify up to the gate without substantial solidification of material within the sprue assembly. The gate is disposed at a plane recessed slightly from the general plane of the solidified disc to prevent any surface discontinuities arising by retraction of the sprue assembly when the mold cavity is opened from projecting above the general plane of the disc.

Abstract: In an ultrasonic diagnostic apparatus using an array type transducer probe (21), an improvement can be made in a tomographic image resolution by electronically focusing ultrasonic wave toward an object to be examined in both directions, i.e., the array direction (Y) and the lens direction (X). During first scanning of the ultrasonic transducer array in the array direction (Y), the signals received from the probe (21) are synthesized each other via delay lines (241 to 245) having predetermined delay times to obtain first scanned signals in real time, so that focusing the reflected ultrasonic wave can be electronically accomplished in the array direction. After accomplishing this first scanning, the probe (21) is mechanically moved to a given position in the lens direction (X) normal to the array direction (Y). Then second scanning operation is accomplished at the above position in the array direction (Y), obtaining similarly first scanned signals. All of the first scanned signals are processed by a delay time control circuit (33) and then stored in the corresponding RAM's (311 to 31 N) respectively, after being converted into the digital signals. Finally, all of the stored first scanned signals are read out and synthesized each other by an adder circuit (34) to obtain second scanned signals, so that focusing the reflected ultrasonic wave can be accomplished in the lens direction (X). The resultant second scanned  i  signals are converted into analogue signals to be displayed : as a tomographic image of the desired diagnostic part in the object.

Filed: 1984-01-17
Abstract: A channel communicator (CC) has a storage array for holding an entry for each channel and for holding a busy vector and an interrupt vector that each have a bit for each channel. The channel communicator (CC) is connected between the input bus and the output bus that connect the channels and an I/O processor (IOP) to processor main store. A message to the channel communicator (CC) includes the identification (ID) of the channel that the message is to or from and the channel communicator (CC) uses this identification (ID) as an address for accessing a channel entry or a bit in a vector. The message also carries a command that controls the channels communicator (CC) to store a data portion of a message or to fetch a channel entry or a vector from the array and load it onto the output bus addressed to the I/O processor (IOP) or to one of the channels. The command also controls addressing a particular one of the vectors. The channel communicator (CC) also has means responsive to a command to perform a sequence of operations for testing the vectors and for testing fields of an entry in the array and for using the results of the test to control the execution of the command.

Abstract: A method and apparatus are disclosed for utilization with pay-per-view television systems in which selected data and pay television programs are transmitted from a central station to a remote subscriber's location. Predetermined credit unit amounts are periodically transmitted by the central station subsequent to a request and appropriate payment by a subscriber. A nonvolatile data storage device is located at the subscriber's location and is utilized to store these credit units. Each pay-per-view television program transmitted by the central station includes an associated cost which may be transmitted by means of an associated debit signal indicative of the credit unit cost for viewing that program or which may be fixed for all programs. Upon selection of a particular program by the subscriber, by means of a subscriber input unit, and verification of a sufficient amount of credit units stored in the data storage device, a control device is utilized to couple the program to the subscriber's television receiver. The control device is also utilized to decrement the amount of credit units stored in the data storage device by an amount equal to the cost of the selected program. In a preferred embodiment of the present invention, graphics generation circuitry is utilized to display to the subscriber the various credit unit amounts stored and utilized.
