Title: An instrument by means of which an observer can ascertain at a glance, the course onwhich an enemy ship or airship is steering
IPC: G01C3/04
Filed: 1924-02-04
Abstract: 229,077. Stuart, J. F. Feb. 4, 1924. Courses, determining. - An instrument for ascertaining the course of an observed ship or aircraft in relation to its bearing comprises observing means for determining the ratio between the apparent lengths of vertical and horizontal distances on the ship &c. and indicating means operated automatically by the adjustment of the observing means to indicate the course. The instrument comprises a pair of half lenses A, B, relatively adjustable horizontally and a pair C, D adjustable vertically. The mounting of the movable half lens A carries a holder E in which is slidably mounted a scale or diagram F, the base of which is divided according to a sine scale while the vertical line is divided into equal parts. The movable half lens C carries a strip G bearing an index mark H. If the vertical and horizontal distances to be compared are the height of a mast and the distance between two masts, and if the ratio of these distances when the ship is broadside on to her bearing is .8, the scale F is adjusted until this division is opposite a mark Z, and the said division is joined to each of the graduations on the base. The two half lenses are then adjusted until in the one case the position of one of the masts in one half image is vertically above that of the other mast in the other half image, while in the other case the top of the mast in one half image touches the water line in the other. The line intersected by the index H on the diagram F then gives the required course.

Filed: 1973-01-24
Abstract: 1398651 Data processing system SIEMENS AG 24 Jan 1973 [8 Feb 1972] 3525/73 Heading G4A [Also in Division H4] A data processing system includes two independent program-controlled real-time processing units and is arranged such that when the load on one of the units exceeds a predetermined value instructions are diverted from the unit to the other unit provided that the load on that other unit is not above a predetermined value. The arrangement is applied to a programcontrolled telephone exchange, and two embodiments are described. In the first two processors B, R are normally connected via switches Ua1-Ua3 and Ur1- Ur3 to respective groups of devices from which they obtain instructions for execution. The load on each processor is measured by a device Mb or Mr which determines the ratio of the times which its associated processor spends idle and executing instructions. A comparator V1 compares the load on each processor with a limit supplied by a device G. A control unit A1 generates control signals ab1-ab3-ar1-ar3 in accordance with the results of the comparisons to re-connect one or more of the instructionsupplying devices to a different processor. For example if processor B is overloaded and R is not, unit FEE may be connected to processor R in response to signal ab1 The number of devices reconnected depends on the loadings on the two processors. It is stated that more processors may be used with a corresponding modification to the comparison and control circuits, units being reconnected to the processor having the lightest load. A line L is provided between the processors for the exchange of control signals, programs &c., diverted instructions being executed following a program switch in the relevant processor. Processor B is normally used to process instructions relating to the control of a telephone exchange and processor R is normally used to process administrative programs, e.g. telephone bills. The system is arranged such that a heavy load on one processor may be expected at times when the other is lightly loaded. If the load on one processor drops below a certain value it may be supplied with additional instructions. The comparison, &c., involved in distributing the instructions may be implemented by programs executed within the processors. The second embodiment is broadly similar to the first except that the processors are "markers" forming part of a telephone exchange system and that instructions are transferred only from one of the "markers" to the other and then only when the load on the other marker is less than a second and lower value. A brief description of a telephone exchange system using such markers and said to be as described in German Specification 1,912,192 is given.
