Abstract: This invention relates to the partitioning of a communications network. The idea of the invention is to divide the logical connections of a communication network into several partitions, each partition representing a certain type of transmission traffic, such as access or regional traffic. The partitioning is based on simple criteria: capacity of an endpoint of a logical connection, representing a node; distance between a pair of endpoints, and traffic category representing the stability of the traffic. By using the partitioning, it is possible to separate a certain type of traffic (a certain type of logical connections) from the whole traffic picture of the network.

Abstract: 1,226,217. Recording apparatus. KODEN SEISAKUSHO K.K. April 9, 1968 [April 14, 1967], No.16996/68. Heading G1J. [Also in Division H4] Apparatus for recording echo signals comprises a group of pens arranged transversely across a record paper which is moved in a direction in the plane of the paper and a switching arrangement for applying the signals to the different pens sequentially, the switching being synchronized with angular scanning of the preferred direction of echo reception. In one application a sonar transducer comprising an array of magnetostrictive elements transmits an acoustic pulse of duration t 1  omnidirectionally or over a sector of angle # and receives echo signals in period T, the elements being coupled to receiving amplifiers via a switched delay network Fig. 5, (not shown) which provides electronic sector scanning, the reception beam direction α being swept repeatedly (with a sweep repetition period t 2 ) through the sector # within the period T. Amplified echo signals are routed in analogue form by switching circuit 5 to polyethylene embedded, rhodium-tipped, stainless steel wire pens 8 in turn for marking electro-chemical recorder chart 9. Circuit 5 is controlled by pulses synchronized with the beam sweep and of repetition period t 3  equal to t 2  divided by the number of pens 8, so that an echo record is produced comprising frames in which azimuth is represented across chart 9 and range is represented along the chart. Azimuth marker lines 12, 13, 14 and range markers 15, 16 may be produced by generators 6 and 7 or by a single generator. In a second application for recording telemetry signals from a sonar carried by a trawl net and indicating net depth or net opening, the telemetred signal corresponding to the sonar pulse transmission is detected by an amplitude discriminator and triggers a pulse train generator which actuates a pen switching circuit to feed subsequent telemetry signals (representing echoes) to the pens in turn. Where the sonar is used for vertical and horizontal sounding alternately, the pen switching circuit and pen group may be duplicated and the pulse train generator output is then applied to the two pen switching circuits alternately so that aligned records for the two sounding directions are obtained on the same chart. The repetition period of the pulse train generator may be varied, or two generators of different repetition period may be provided, to obtain recordings covering selected ranges or partial ranges. Details are given of a pulse train generating arrangement and of a transistorized pen switching circuit which preserves a proportional relationship between the amplitudes of the echo signal and the signal applied to a pen. It is stated that the invention may be applied to recording radar data.

[Also in Division F2] The eccentricity of a non-rotary ring 91, tracked by spring-pressed vanes 96 on a rotor 95 of a pump for supplying pressure liquid to actuate clutch and brakes in an automatic transmission on a motor vehicle, is adjusted by the action of delivery pressure on a piston 100, in opposition to an adjustable spring 98, to maintain constant delivery pressure. In Fig. 12D, (not shown), the spring 98 is replaced by a second piston, smaller than 101 and subject directly to delivery pressure, which latter feeds the system main through an orifice, the downstream pressure of which acts on the larger piston so that pump eccentricity vanes with the pressure-drop across the orifice and hence system flow.
