Title: Methods and apparatus for digitally signaling  sounds and tones in a pcm multiplex system

Abstract: Abstract of Disclosure Different ones of a plurality of sounds or tones are digitally signaled selectively in the different time slots of recurring frame cycles by initially storing a group of PCM samples for each sound in addressable memory. As each given time slot is read out to a common bus, and as successive cycles occur the address signals applied to the memory during any given time slot are progressively changed to cause repeated scanning of the samples of the preselected sound. After address signals for one time slot have been pulled from a read/write memory, they are replaced by writing "next sample address" signals under the control of characteristic-representing signals stored in a sequence memory and read out by call signals representing the preselected sound for any time slot.                The preselection permits any of the sounds to be placed in any of the time slots or channels, but in the preferred form some of the time slots always carry the same sounds (fixed tones) while others may have their carried tones ("switched" or register tones) changed by commands received asynchronously from a central control unit.                The methods and apparatus utilize ROM (although RAM may be employed) to pair different ones of the several sounds with different ones of several on/off schedules to form a larger plurality of distinctive "tones", any one of which may be digitally signaled in any time slot or channel.     The method and the apparatus permit some of the tones to be "intercept" tones formed by two sounds transmitted alternately with a predetermined duty cycle.

Abstract: ABSTRACT    A component of a polymerization catalyst is prepared by reacting an organo-magnesium halide with a solid, inorganic oxide, then reacting the product with a Lewis base compound, particularly an ester and finally with titanium tetrachloride. After reacting the organo-magnesium halide with the inorganic oxide it may be treated with a halogenating agent before it is reacted with the Lewis Base compound. The product obtained is combined with a Lewis Vase and used to polymerise an olefine monomer particularly propylene or mixtures of ethylene and 1-olefine containing at least 4 carbon atoms. The catalyst system has a high activity, is stereospecific and has a lower proportion of halogen than some other catalyst systems.

Abstract: ABSTRACT         A machine is provided for grinding concrete floors and the like, particularly for rough finishing and rough grind-ing of concrete floors, such work requiring high grinding capacity.  To deal with the problem of the high torque generated by the grinding tools, a torque which with conventional machines has to be absorbed by the operator, the machine is equipped with at least three wheels which, when grinding is carried out, are designed to rest on the underlying surface and to be loaded by such an amount that the frictional force between the wheels and the underlying surface at right angles to the plane of the wheels exceeds the torque.  Since the chassis wheels support the machine, the grinding tools can be arranged to move freely in a vertical direction relative to the chassis.  The load on the grinding tools can thereby be varied, allowing one and the same machine to be used for different types of grinding work merely by changing the grinding tool and adjusting the application pressure of the tools on the underlying surface.

Abstract: An apparatus is provided for the interconnection of two mobile carriages which are connected by a rigid beam and guided along parallel guide rails. The apparatus permits the simultaneous and identical movement, with respect to both direction and distance, of the carriages along the respective guide rails. The apparatus comprises two generally symmetrically disposed cables, each of which is attached at one end to an end of one rail and at its other end to a diagonally opposed end of a parallel rail. Intermediate the attachment points, the cables connect the carriages by resting on and being supported by return pulleys which are integral with the carriages. Each cable thereby describes a generally Z-shaped configuration. The Z-shaped configurations are symmetrically disposed in order to cause, during the displacement of one carriage, the tensioning of one of the cables, and thereby cause the other carriage to be identically and simultaneously displaced.

Abstract: ABSTRACT OF THE DISCLOSURE           A fuze for a non-spinning projectile including a body, a cap rotatably mounted on the body, a hammer in the cap, a detonator in the body, a detonator safety device and a muzzle safety device.  The fuze comprises pivot means within the body.  A rotor is mounted on the pivot means between a safety position and an armed position around an axis transverse to the axis of said fuze.  A detonator primer is carried by the rotor, an inertia mass is mounted on said pivot means, and a support is disposed in front of said rotor.          A first spring connects the inertia mass to the support, and retaining means are secured to the cap to prevent the inertia mass from pivoting against the action of said spring.  Clutch means are rotatably secured to the pivot means and they mesh with the fuze body to prevent rotation of said rotor whereby immobilizing of the rotor in an inclined position with respect to the axis of the fuze places the detonator primer out of reach of said hammer and away from the detonator to provide detonator safety.

Abstract: BRW:ajh ELECTRONIC IDENTIFICATION SYSTEM     ABSTRACT          An electronic identification system for reading a pre-defined identifier code.  A preferred application provides a credit card sized "identifier" which includes an array of electrical inductors, some of which are elec-trically connected in a selected pattern to define the identifier code.  The identifier may be positioned close-ly proximate to a substantially identical inductor array included in a "reader" so that each identifier inductor is centred over a corresponding reader inductor.  An alternating current is applied to each reader inductor in turn to induce an electromagnetic field in the region surrounding the driven inductor.  The electromagnetic field so pro- duced induces a voltage across the identi-fier inductor centred over the driven reader inductor.          If that identifier inductor is electrically connected to another identifier inductor(s) a current will flow in the other inductor(s) and a second electromagnetic field will be generated in the region(s) surrounding the connected inductor(s).  The second electromagnetic field induces a voltage across reader inductor(s) centred under the con-nected inductor(s).  Each reader inductor is separately sensed.  If a current output signal is sensed at reader inductor(s) other than the driven inductor, it may be assumed that identifier inductor(s) corresponding to the driven inductor and to the reader inductor(s) at which an output signal is sensed have been electrically connected.          A master control device may thus determine the identifier code by noting those identifier inductors which are elec-trically connected.
