Title: Casting process and system
Inventor: MUSSCHOOT ALBERT
IPC: B22D46/00
Filed: 1994-05-10
Abstract: In order to effectively enhance the overall efficiency in casting operations, a process and system for cooling and cleaning a casting is disclosed. The process and system include removing the casting from a molding machine after it has been formed. The casting is then moved to a punch-out station for removing it from a sand mold. Next, the casting is moved to a shake-out station for shaking residual sand from it. The casting is then conveyed away from the shake-out station on a cooling conveyor. Next, the temperature of the casting is monitored at or near a downstream end of the cooling conveyor. The casting is then transferred from the cooling conveyor into a vibratory cooling drum where it is further cooled. In addition to these unique aspects, the process and system includes controlling the rate of cooling of the casting within the vibratory cooling drum.

Abstract: An ATM switching system includes PVC allocation circuits 13-i corresponding to output queues 14-i is disclosed. At the time of arrival of the leading cell of each burst data, if the output line has a room, the PVC of the burst data is stored as information for admission and identification. The subsequently-arriving cells having the same PVC identification information as the stored identification information are input to an output buffer, and the cells of the remaining burst data are all discarded. Even when a plurality of burst data compete for the same output line, the fact that all the cells other than the first-arriving admitted burst data are discarded prevents the cells from being input other than within a predetermined bandwidth and localizes the burst data affected by the cell discarding due to output queue overflow.

Title: Atm queuing and scheduling apparatus
Inventor: HAYTER ANDREW T
IPC: H04L12/56
Filed: 1995-03-07
Abstract: The apparatus comprises a buffer store connected to an input line upon which ATM cells are received, and an output line upon which ATM cells are transmitted. A control means receives, for each cell, a channel identifier and a path identifier from which a first signal is generated indicative of a maximum delay value which is applied to the buffer store and used to schedule the particular cell for transmission, on a calendar controlling a sustainable cell rate. The control means generates a second signal indicative of a minimum delay value which is applied to the buffer means and, in conjunction with said first signal is used to schedule the particular cell for transmission, on a calendar controlling the peak cell rate. The apparatus can also handle routing information, where a group of channel connections define a Route which share a peak cell rate for the Route and are scheduled on the peak cell rate calendar.
