Abstract: An ionization field is produced across the pumped air flow to a fuel combustion process to increase the content of oxygen in the stream, and the stream reactivity. This ionization field may be produced between a sharp electrode and a grid or sheet, positioned in a shielded structure like the filter housing on the engine intake. Alternatively, an ultraviolet light source may be used to ionize the oxygen in the air stream. In either form the air stream may be compressed before its ionization and then may be injected into the exhaust products of the combustion process. The ionization power may be modulated along with the demand. Thus the throttleposition may be sensed to modulate the voltage multiplier levels across the electrodes straddling the air stream, in accordance with the demand.
Abstract: A training attachment useful in reinforcing proper glove positioning in the course of fielding a baseball includes a switch assembly that is provided with a switching lever and that is securable to the back of the glove. When thus secured the switching lever extends beyond the glove digit ends, to be deflected against the ground. A buzzer may then be attached to the body of the player connected by a harness to the switch. In this manner correct glove alignment in anticipation of the incoming baseball deflects the lever, thus exciting the buzzer.
Abstract: Apparatus and method for selectively securing a shelf separator array to display shelves includes a plurality of openings formed in the shelves, and resilient clips that are securable both to the separator structure and in the clips. In the first form the clips are provided with resilient split retaining clamps engageable to the extrusion forming the separator structure and resilient opposing projections conformed for receipt in a selected opening. In another form, the extrusion forming the separator structure includes a groove formed longitudinally therein in which fitted portions of the clips are slidably received. The projections depending from the fitted portions are then useful for insertion in a selected opening in the shelf.
Abstract: A virus protection system, which may be coupled to an external input/output port of a disk operated data processing system, includes a read only memory in which a redundant partition table is stored, duplicating a partition table on the disk. The virus detection system further includes detection logic which monitors a transfer of data from the disk to a system random access memory and which detects data transfers to a high region of the system memory during initial portions of the transfer. When a virus is detected, the redundant partition table is written onto the disk.
Abstract: A sinker assembly includes a fared sinker body of an elongate oval shape in which the longitudinal slots are formed in an orthogonal, crossing arrangement. The first of these slots extends to the lateral exterior of the body while the second one is fully within the body structure. A plastic retainer is then received into the second slot, and includes a longitudinal bead on its surface for compression against the slot edges formed at their crossing. The retainer may include a tab at one end and one end of the body may be cut away to accommodate this tab.
Abstract: A grommet assembly useful in attaching articles to a carrying structure includes a first and second annular grommet piece, each conformed for mating engagement to the other, the first grommet piece including a central boss extending axially from one side of an annular base provided with a tapered cavity therein. The second grommet piece is similarly provided with an axial boss tapered on the exterior to fit within the cavity. The free edge of the second boss includes a peripheral bead conformed to engage an interior recess in the cavity. The grommet pieces may be joined to each other by a flexible strap and the first piece may include a bedded washer on the surface opposite to the first boss. Both the grommet pieces and the strap may be formed of a resilient material structure and when the bosses are mated in each other the subsequent compression of the assembly will expand the combined sectional dimension thereof for compressing against the surfaces of any suspension device.
Abstract: A well cleaning attachment useful as a part of a collection of tools sent down a well bore on a tubing string includes a tubular mandrel provided with a plurality of longitudinal slots in which corresponding knife carriers are inserted. Each carrier is bedded on a leaf spring for radial motion within the slot and each is provided with a spring biased blade extending pivotally to the exterior. Two collars then fix the carriers within the slots, the same collars also engaging the periphery of the mandrel.
Abstract: A water pressure cleaning assembly useful in cleaning out the perforations in a well casing includes a mandrel structure defined by an upper cylindrical segment and a lower conical segment. An upper and lower annular seal is movable respectively along the upper and lower segments to allow relative motion of the mandrel structure within the annuli thereof. This lateral motion then allows the passage of the assembly across irregularities in the casing.
Abstract: Apparatus, for winding coils of various geometric configuration, includes a rotary spindle provided with a mounting face on which a segmented core spool assembly is mounted. This assembly is thus fixed by a clamping flange extending a tongue into the spindle. A cam and a swash plate on the spindle then articulate a pivoted arm on which a wire guide is fixed. The cam is then useful in minimizing the dynamic components of the wire wound onto an irregular shape while the swash plate controls the winding lace.
Abstract: A U-turn signaling attachment useful with the turn signal stalk of a motor vehicle includes a frame conformed for engagement to the stalk and a lever pivoted on one end of the frame. A cam edge is fixed to the lever to oppose one end of a push rod which, at its other end, oppposes a double lobed surface attached to the steering column. The cam edge, at its center position, is chamfered transversely to clear the push rod during fore and aft motion.

Abstract: A method and apparatus are disclosed for recognizing spoken commands uttered by a user and for generating responsive control signals once the command is recognized. In accordance with this disclosure the audio signal is converted into a series of count bytes representing the time between the audio signal zero crossings, and all the count bytes of the full command are then segmented into equal temporal groups and sorted within each segment into a set of frequency class intervals which are based on a computation of substantially equal byte activity in all the words comprising the command lexicon. In this manner, lower and higher frequency groups are selected for equal significance. The uttered words are then compared against stored words similarly transformed according to segment and frequency interval and if the comparison conditions are satisfied the command is executed; if not, an indication is provided to the user to repeat the command. Segmenting produces a segment period.
Abstract: A substantially rectangular confining envelope characterized by an exterior and interior polymeric skin bonded to each other in bonding seams which include gaps for conveying air to the adjacent sections. The longitudinal edges of the envelope may include fastening devices for engagement of the envelope around the body of a patient. One or more of the gaps may then be selectively closed to control the distribution of compressed air in the envelope.
Abstract: A medication dispensing assembly which comprises a stationary annular plate in which a boss formed on a moveable plate is received. The boss is provided with a set of deformations on its periphery which are useful to close a switch. A drilling in the moveable plate, aligned at each depression, is then useful to receive an insert pin to fill the deformation. A microswitch riding on the periphery of the boss is then closed at each unfilled deformation to provide an audio and visual signal. The moveable plate is provided with a set of depressed sectors each in alignment with a corresponding deformation on the boss and each provided with a dispensing hole. A single dispensing port is formed in the stationary plate and when the sector is advanced for dispensing to this port the visual and audio signals are set off.
