Abstract:

A receptacle, which is adapted for nesting and stacking with similar receptacles. The invention, the receptacle is intended in particular to be utilized as a food pan for the receiving and storing of hot or cold food items, and, which may be employed in connection with buffet or steam tables, among other diverse uses thereof. The receptacle is preferably constituted of a metallic material, such as aluminum or stainless steel, which is compatible with food service requirements and sanitary prescriptions or regulations having a generally rectangular flat bottom, and wherein lower side and end walls extend upwardly in an outwardly angled slope from rounded edges connecting the receptacle bottom to the lower ends of the walls. At the upper ends of each of the side and end walls, these extend into outwardly and upwardly curved wall structures, which form a curvilinear ledge. The upper and resulting radially outer edge of this ledge extends into the lower ends of upper side and end walls which slope inwardly towards their upper ends to define a receptacle opening somewhat closer to the size of the opening of the receptacle defined by the upper ends of the lower side and end walls of the receptacle.

Abstract:

In a system that transmits packets containing timestamps and information from a transmission site to a reception site at a transmission bit rate the packets may experience jitter, i. e. variable delay, during transmission. In such a case, the packets are temporally shifted relative to the timestamps and to other packets. Where the timestamp values are inserted into selected packets prior to transmission and that timestamp represent the value of the transmission site clock, the method and apparatus of the present invention substantially removes the jitter and adjusts the timestamp values prior to reception of the packets at the reception site. The present invention achieves this goal by receiving the packets at an intermediate site that has a local clock operates at a nominal frequency substantially equal to the nominal frequency of the transmission site clock and uses that clock as a jitter-free clock to correct the packets. The packets are stored in a buffer at the intermediate site and output from the buffer at a controlled rate to maintain a substantially constant average transit time of packets through the buffer. Before the packets are output for reception at the reception site the timestamps of selected packets are modified to reflect the new temporal relationship between packets due to the controlled rate of output from the intermediate site.
