Abstract: ABSTRACT OF THE DISCLOSURE           A model horse is resiliently mounted to permit a child rider to cause motion of the horse having vertical and/or horizontal motion components.  A trotting gait sound is generated in response to detected vertical motion, and a walk and/or gallop gait sound is generated in response to detected horizontal motion.  The selection as between the walk and gallop gait is preferably based upon the amplitude of horizontal motion.  The different gait sounds are obtained by generating a basic "clop" (hoofbeat) sound, and, repeating the clop sound in a different time sequence for each gait.          In the preferred embodiment of the invention, the sounds of a horse's "snort" and "whinny" are also generated during riding.  The sounds produced in accordance with the inven-tion are obtained by digitally forming audio frequency signals and controlling the envelope of the audio frequency signals.

Abstract: ABSTRACT.       In electrical discharge apparatus, such as a gas laser, in which a glow discharge is to be produced in a gas between two electrodes, at least one pre-ionising member is placed near the discharge space and extending between the electrodes so that current flows in the member which is made of intermediate resistivity material such as crystalline semiconductor material.  As a result, the discharge space is pre-ionised which assists initia-tion of the main discharge.   The pre-ionisation may be due to the formation of numerous small arcs between the electrodes and the member and the resulting production of ultra-violet light.

Abstract: TITLE A TWO MAGNET ASYMMETRIC DOUBLY ACHROMATIC BEAM DEFLECTION SYSTEM INVENTOR Ronald M. Hutcheon The beam deflection system includes two dipole magnets for deflecting a charged particle beam in a deflection plane. The first magnet bends the beam in a path having a radius P1 and a deflection angle .theta.1 greater than 180.degree.. The first magnet has an effective exit edge at an angle (90.degree. - ?1) with respect to the beam path. The second magnet further bends the beam in a path having a radius P2 and a deflection angle .theta.2 where 225.degree. ? (.theta.1 + .theta.2) ? 280.degree.. The effective entry edge of the second magnet is at an angle of (90.degree. - ?2) to the beam path. In the usual practical case the effective interior edges of the two magnets are roughly parallel, that is, ?1 ? -?2 and the doubly achromatic properties are obtained to first order when the angles satisfy the following formula: ?1 ? -?2 2?2 ? .theta.2 -(.theta.1 - 180.degree.), and when the distance D between the effective edges of the two magnets is set so that the dipoles produce equal beam dispersion in the drift distance between them. For the case of 270.degree. total bend with P2 = P1 this occurs at a distance D, given by <IMG> .

Abstract: ABSTRACT     Under the I/O protocol required by conventional computer architectures, peripheral devices communicate with each other via the CPU of a host computer.  That requirement necessitates two separate data transfers and cuts the data transfer rate by one-half.       This invention discloses a data processing system having an architecture that will allow high-speed direct device-to-device data transfers independently of a computer memory.  The system consists of a host computer interconnected with a remote signal processing subsystem.  A Direct Device Access Bus and a plurality of data processing devices are provided.  The supervisor includes means for subdividing the plurality of devices into several device sets by assigning a unique transaction code to the members of each set, a different code being used for each different set.  A controller associated with a Signal Processing Subsystem supervisor, selectively interconnects desired ones of a set of data processing devices via the Direct Device Access Bus to provide direct communication between the selected devices of each of several device sets on a substantially concurrent basis.

One side, i.e., an inner side, of each of the seal rings projects from the triangular recess to contact the edge of the valve disc to form a fluid-tight seal in response to fluid pressure acting on a convex face of a seal ring to flatten the seal ring.  The other side of each of the seal rings contacts a respective corner of the recess with the convex faces of the seal rings facing each other.  A preload member is located in the space between the convex faces of the seal rings to apply a pressure to the convex faces to induce a contact between the inner side of each of the seal rings and the peripheral edge of the valve disc.
