Abstract: ABSTRACT     The invention provides a method of priming a blank or bulleted rimfire cartridge comprising the steps of a) dosing into the rimfire case a quantity of a substantially dry, powdery, relatively insensitive premix comprising, in predetermined proportions, at least two materials that will, in the presence of a liquid reaction medium, react together forming a primary explosive compound, b) compacting the premix so as substantially to fill the rim of the case therewith, c) dosing a quantity of the liquid reaction medium into the case so as to cause said materials to react together forming the primary explosive compound and d) drying the primer. By compacting the premix into the rim before the addition of the liquid reaction medium, the conventional spinning step may be dis-pensed with, thereby making the priming process safer and more economic.

Abstract: ABSTRACT            A safety device for a banking vehicle includes a pair of cylinders which extend to hold the superstructure in an upright position.  The cylinders are hydraulically connected to an accumulator which provides a pressurised fluid reservoir.  A valve controls flow from the accumulator to the cylinders.  Upon detection of a failure in one of the vehicle systems the valve moves to a position in which fluid flows from the accumulator to extend the cylinders.  A pilot operated check valve is positioned between the accumulator and the cylinders to hold the cylinders in the extended position until the failure is rectified.

Abstract: HARVESTING MACHINE INCLUDING CHOPPER MEANS       ABSTRACT OF THE DISCLOSURE     A harvesting machine comprising a threshing mechanism, a transvers rotary separator mechanism having discharge outlets adjacent its opposite ends, and discharge channels in register with the discharge outlets leading to a common strawhood. The separator mechanism is arranged spirally to convey crop material received from the threshing mechanism toward each of its ends while submitting the crop material to a separating action and to forcefully eject crop material through said discharge outlets and through said discharge channels in the direction of the common strawhood.  A crop material chopper device is associated with each discharge channel and is disposed out of the normal path of the crop material through the respective discharge channel.  A deflector device associated with each chopper device is adjustable between a position retracted from said normal path of the crop material and a further position across said normal path.  The arrangement is such that in the former position of the deflector device crop material forcefully issuing from the separating mechanism by passes the associated chopper device in moving toward the strawhood and that in the latter position said crop material is deflected from said normal path toward the associated chopper device.

Abstract: A b s t r a c t :            A process for producing fermented alcoholic products with a low diacetyl content, such as beer, wine or ethanol containing fermentation products to be processed to concentrated ethanol, comprises fermenting a carbo-hydrate containing substrate with a microorganism, preferably yeast, and treating the substrate with an acetolactate converting enzyme, such as acetolactate decarboxcylase, during or in continuation of the fer-mentation. The process can also be used in connection with malo-lactic fermentation carried out during maturation of wine. The enzyme may be used in a free, dissolved state or in an immobilized state. In the acetolactate decarboxylase treatment small amounts of acetolactate formed by secondary fermentation processes are decarboxylated to acetoin instead of being slowly decomposed to diacetyl.

Abstract: METHOD AND APPARATUS FOR CONTINUOUS WORD STRING RECOGNITION                ABSTRACT OF THE DISCLOSURE   A speech recognition method and apparatus for recognizing word strings in a continuous audio signal are disclosed.  The word strings are made up of a plura-lity of elements, and each element, generally a word, is represented by an element template defined by a plura-lity of target patterns.  Each target pattern is repre-sented by a plurality of statistics describing the expected behavior of a group of spectra selected from plural short-term spectra generated by processing of the incoming audio.  The incoming audio spectra are pro-cessed to enhance the separation between the spectral pattern classes during later analysis.  The processed audio spectra are grouped into multi-frame spectral pat-terns and are compared, using likelihood statistics, with the target patterns of the element templates.  Each multi-frame pattern is forced to contribute to each of a pluarality of pattern scores as represented by the ele-ment templates.  A concatenation technique is employed, using dynamic programming techniques, to determine the correct identity of the word string.

Abstract: METHOD AND APPARATUS FOR INDIVIDUAL CONTROL      OF INJECTION MOLD SHUT-OFF BUSHINGS                     ABSTRACT OF THE DISCLOSURE    A method and apparatus for multiple cavity injection molding which permits individual variation of gate opening time for mold shut-off bushings.  The gate pins for the shut-off bushings are con-trolled by individual double-acting fluid motors, the bushings being fed by a common manifold.  Gate opening is thus not dependent upon attainment of a predetermined injection pressure.  Closure of the gate for each cavity will permit material to be fed faster to the other cavities.  Novel means is provided for securing each gate pin -to its actuating cylinder, which minimizes heat transfer to the motor, accommodates expansion of the material manifold and permits gate opening adjustment.  The fluid motors are end-mounted of an actuating fluid manifold, allowing close juxtaposition.  A cycle counter may be used to control inventory.

Abstract: MULTIPLE ACCESS DATA COMMUNICATION SYSTEM CONTROL            Abstract A variation on a carrier sense multiple access/collision detection (CSMA/CD) system protocol for local area, packet, random access, broadcast networks is disclosed for effectively servicing both voice and data traffic.  When the instant method is used, a mix of periodic voice traffic and aperiodic data traffic can be transmitted on a channel without the voice packets colliding.  Also, an upper bound on the delay experienced by the periodic traffic can be established.  In the instant method, aperiodic sources contend for a channel as in conventional CSMA/CD networks.  However, unlike conventional protocols, periodic sources transmit a preempt field, responsive to which aperiodic sources terminate transmission.  Also unlike conventional protocols, a periodic "time slot" may be delayed up to one packet transmission time when the network is busy transmitting aperiodic data.  Additional information can be transmitted in an overflow field so that a receiver can supply periodic samples at regular intervals with the advantageous result of obviating discontinuities in a reconstructed analog speech waveform.  Also unlike conventional CSMA/CD networks, the system capacity can be fully utilized by periodic sources.  Still further, the instant method contemplates a system with no centralized control to assign "time slots" or to reallocate capacity between periodic and aperiodic sources.  In addition, movable time slots allow timing discrepancies between periodic sources to be tolerated.
