Title: Time division system for synchronizing functions controlled by different clocks
IPC: H04J3/06
Filed: 1976-07-28
Abstract: Synchronization control circuit for a time divisional data transmitting and receiving system. Data is received at an exchange at a clock rate determined by the transmitting station and is stored in memory at that rate. Read-out of data from the memory is based on the internal clock rate of the exchange. Since only one operation - read or write - can occur on a memory at any one time and the operations are controlled at rates which may be out of synchronism with one another, conflicts may occur. To prevent such conflicts, a time shift of predetermined duration is inserted between operations when the out-of-synchronism interval is less than a predetermined time interval.

Patent ES-474332-A1 (ES)
Title: Controlled flow cooling system for low weight reciprocating engine
IPC: F02B75/22
Filed: 1978-10-18
Abstract: A light metal die-cast head and cast iron block employ a low volume cooling system which cooperates with the differing thermal conductivity properties of said head and block. The cooling concept eliminates the conventional intricate water jacket and replaces it with continuous grooves which wrap hemi-cylindrically about each combustion cylinder in a thinly spaced relation. The grooves are exposed along their length at the deck surface of either the head or block. The total fluid mass in the system is reduced to as little as 1/5. There are two such grooves in the block which (a) extend from one end thereof to the opposite end, (b) are on opposed sides of the cylinder galleys and (c) have substantially no transverse flow in order to promote laminar or controlled flow. There is a critically located straight drilled passage along with two such grooves in the head, the combination of which is restricted in throat area when compared to the throat area of the grooves in the block this results in a high velocity flow in the head and a low velocity flow in the block when they are connected in series flow relation. The straight longitudinally drilled passage (which may include one or more of such passages) is located in the head separating the exhaust and metal valve guides the passage has a throat area equal to or less than the throat area of either of the grooves in the head. Heat extraction is more easily and flexibly programmed to achieve not only a more uniform wall temperature throughout the head and block, but permit a desirably slightly higher average wall temperature than conventional light metal heads for improvement in fuel economy and thermal efficiency.
