Abstract: Apparatus for compensating moments created by inertia forces in an internal combustion engine (2) used for a ship's propulsion comprises a balancer (8) spaced in the fore-and-aft direction from the engine and including one or more rotary unbalanced masses (9). Each unbalanced mass is driven by a positive displacement hydraulic motor (12) connected through feed and return conduits (14, 15) with a positive displacement hydraulic pump (13) driven by the engine (2) in such a way that the rpm of the mass is equal to or twice the rpm of the engine crankshaft (3) and that a desired phase relationship between the rotation of the mass and the movements of the oscillating masses of the engine is maintained. The hydraulic drive provides a simpler and cheaper apparatus as compared to known electrically driven balancers.

IPC: B65D65/40
Filed: 1980-10-06
Abstract: A packing laminate which is intended to be converted into packing containers is often provided with crease lines in order to facilitate folding and shaping. At the places where crease lines cross each other a multiple folding of the laminate takes place on conversion into packing containers which, among otherthings, means that small cracks are formed in the different material layers, so that the tightness of the packing container is put into jeopardy. In accordance with the invention, a packing laminate is proposed in which these difficulties are overcome in that the laminate is provided with specially designed auxiliary crease lines which in the region of the laminate, where the folding lines cross each other or meet, replace the (main) crease line guiding the folding line. The auxiliary crease lines are situated at such a distance from the main crease line that the folding line is not affected, that is to say, the folding line will after folding not coincide in any part with the auxiliary crease lines. The auxiliary crease lines will merely be situated on either side of the folding line in such a manner that the take up and guide the crease formation or "wrinkling" which normally arises in the inner laminate layer in the folding line itself.

IPC: H04L12/413
Filed: 1981-10-01
Abstract: This disclosure relates to a station for a data transmission network which is adapted to operate in a cyclic mode for contending for access to the network channel along with other stations of the network. The three states of the cycle are the idle state, the packet-being-transmitted state and the acknowledgement period state. Each station will not begin transmission until it determines that the channel is in an idle state. Once the station has determined that the channel is idle, it will then delay for a period of time that is randomly chosen and, if the channel is still idle, will then begin transmission. In this way, contention conflicts between stations is minimized without unduly restricting communication between stations. Following transmission, the channel will again be quiescent a short period of time before the acknowledgement signal is transmitted from the receiver. Each packet of data to be transmitted is of a fixed length so as to provide for synchronization between various stations contending for access to the channel.
