A flow control mechanism for use in a high speed packet switching network where calls are multiplexed on network trunks with each connection using a reserved amount of the total bandwidth. Data terminal equipments access the network via access nodes. Each access node includes a Leaky Bucket component which maintains a refillable token pool. Each time an incoming packet is received by the leaky bucket component, the number of available tokens is compared to two predetermined threshold values. If the number of tokens is less than the low threshold, acknowledgments of received packets are stopped, inducing an interruption of packets transmitted by the emitting terminals. Interrupting packet transmission will lead to a regeneration of the number of tokens in the token pool. If the number of tokens reaches the high threshold, acknowledgments are again generated to restore packet transmissions. The first and second thresholds are greater than zero, reducing the chances that a packet will be marked as being discardable.

A preventive X.25 flow control mechanism for use in a high speed packet switching network where calls are multiplexed on network trunks with each connection using a reserved amount of the total bandwidth. X.25 data terminal equipments access the network via access nodes. Each access node includes a Leaky Bucket component which maintains a refillable token pool. Each time an incoming packet is received by the leaky bucket component, the number of available tokens is compared to two predetermined threshold values. If the number of tokens is less than the low threshold, acknowledgments of received packets are stopped, inducing an interruption of packets transmitted by the emitting attached X.25 terminals. Interrupting packet transmission will lead to a regeneration of the number of tokens in the token pool. If the number of tokens reaches the high threshold, acknowledgments are again generated to restore packet transmissions. The first and second thresholds are greater than zero, reducing the chances that a packet will be marked as being discardable.

A deep-fry pan for industrial deep-fryers. The pan is hermetically closed during operation to minimize contact between oil contained in the pan and ambient air and to minimize pollution of the room in which the fryer is located.
