Title: Indicator apparatus for determining the miss distance  of a projectile in relation to a fixed or moving  target
Inventor: SOEDERBLOM OLOF
Filed: 1979-02-07
Granted: 1982-10-05
Abstract: ABSTRACT           Indicator apparatus for determining the miss distance of a projectile in relation to a fixed or moving target, compris-ing pressure-sensing transducers intended to sense the pressure wave generated by the projectile in a least four points, and means for generating corresponding electrical signals therefrom.  The apparatus further comprises computer circuits, calculating the distance to the point of origin of the wave, i.e. the so-called "bang generation point", in response to the characteristics of the pressure wave.  This distance has been called the "miss distance" in previously known indicator apparatus, but in accordance with the inven-tion the miss distance is defined as the shortest distance between the projectile and target, and one object of the invention is to indicate this distance and the exact position of the projectile when it is at the miss distance from the target.  In the indicator apparatus in accordance with the invention, the direction of the trajectory is calculated by means of said at least four pressure transducers arranged at the corners of a polyhedron.  By measuring the time dif-ferences for the passage of the pressure wave past the press-ure transducers in the transducer system, the exact position of the bang generation point can be given in relation to the pressure transducer system from these time differences and the measured distance to the point.  The indicator apparatus also comprises a second transducer system which can sense either the height of the first pressure transducer system above a horizontal plane, or the passage of the pressure wave at a further instant.  From these data the computer cir-cuits can give the trajectory direction which, together with the bang generation point gives the required trajectory.  For shooting at fixed targets, the computer circuits give a second point on the trajectory which, together with the bang generation point, gives the trajectory perse.

Abstract: SELECTIVELY MODIFIABLE PHRASE STORAGE FOR A TYPEWRITER                 Abstract Printing operation sequences (e.g. code sequences representing phases of text) entered along with identifier codes by means of typewriter keyboard are stored for selective individual retrieval and may be replaced on an individual basis as the needs of the typewriter operator may dictate.  By using a special end loading procedure for adding new sequences, both storage overlapping and build-ups of unused storage locations between sequences are avoided so that storage integrity is maintained while storage usage remains, nonetheless, efficient.            In a preferred implementation, individual sequence retrieval capabilityis achieved by including in the respective sequences a common delimiter code along with a sequence identifier code.  During bulk code transfers that occur when changes are made to the stored sequences, such delimiter and identifier codes are shifted routinely without being distinguished from the sequences they separate.

Abstract: ABSTRACT   A method of cooling a flow of a molten material involves simultaneously subjecting the flow to a stirring action which is such that the temperature of the material is substantially the same at any point in any one plane perpendicular to the direction of flow.  The cooling may be applied to a molten material to bring it either closer toits melting point or liquidus temperature or to bring it within its freezing range where this is desired as in for example, the pro-duction of metallic slurries.  In apparatus for cooling a flow of a molten material having means for cooling and means for simultaneously stirring the flow, both means preferably comprise at least one element extending transversely with-in a duct through which the flow is directed.  The element, which may be a hollow rod arranged to carry a flow of a coolant, is preferably made of a highly conducting material e.g. graphite or a metal whereas the walls of the duct are preferably of an insulating material.  By this means nearly all of the cooling effect can be concentrated in the elements which permits close control over the cooling action.  The number, arrangement and size of the elements will depend on the degree of cooling required and on the amount of stirring which is nec-essary to achieve even cooling along the duct. The cooled flow, after passing through the duct, is conveniently led into a mould or series of moulds or into a casting machine in which solidification to give a shaped article takes place.
