Abstract Of The Disclosure An improved endodontic instrument includes a tapered working portion defined on a flexible shaft. The working portion in-cludes a plurality of spiral rotationally bi-directional cutting edges thereon. The instrument includes a tapered tip defined on the flexible shaft and intersecting an end of each of the cutting edges of the working portion. The tapered tip has a greater angle of taper than does the tapered working portion. The tapered tip is shaped such that the sharp cutting points which are normally present at an intersection between the ends of the cutting edges and a standard 75° included angle conically tapered tip are substantially eliminated so that lateral transportation of the instrument when cutting a curved root canal is reduced as compared to an otherwise similar instrument having a standard 75° included angle conically tapered tip.

Method and Apparatus for Controlling Switches in an Inverter Abstract A method and apparatus for controlling switches in an n-phase static inverter of the bridge type is dis-closed wherein the inverter includes n pairs of switches connected across two DC voltages, with a phase output being developed at the junction between switches of each pair. In such an inverter, at any particular time, n1 phase outputs are connected to one of the DC voltages while n2 phase outputs are connected to the other DC vol-tage, where n1 ? n2 and n1 + n2 = n. The n1 phase out-puts are identified by logic circuitry and the sw?tches associated with such phase outputs are operated during times when a pulse width modulation waveform is in a low state so that all phase outputs are connected to the same DC voltage. The method and apparatus of the present in-vention reduces the number of switching occurrences to the minimum required to achieve defined applied voltage pulse width modulation. Further, the method and appara-tus of the present invention does not result in the gene-ration of regenerative currents, and hence various types of DC sources may be used and the DC bus filter may be reduced or eliminated.

KEYLESS ACCESS CONTROL AND SECURITY SYSTEM ABSTRACT OF THE DISCLOSURE A keyless access control and security system especially adapted for use with an automobile comprises a piezoelectric permutation touchpad unit which can be affixed, without requiring bodywork, to the outside of the vehicle's door in the key cylinder aperture. The touchpad is illuminated when touched and is therefore usable in the dark. The person seeking access must enter the correct access code combination on the touchpad to open the door and/or the trunk. The touchpad is connected to a remotely located logic circuit which controls access. The circuit provides for a signal of low intensity, indicating that a correction in the code entered into the touchpad should be made and, after a time delay, an alarm of high intensity, if no correction is made. Upon activation of the alarm, the headlights are flashed, the horn is sounded, or both. In order to enable a parking attendant, repairman, or some other authorized person to have access to the automobile without revealing the access code, the logic circuit can be programmed, by operation of the touchpad, using the proper access code and a further secondary code, arbitrarily selected, to provide access to the automobile in response to the secondary code, which later can be erased.

ABSTRACT OF THE DISCLOSURE The present invention concerns a procedure for produc-ing refined groundwood pulp from chips, in the procedure being used softwood and hardwood chips in such manner that the pulp that is obtained contains in mixture both matter from softwood and matter from hardwood. In the procedure, the hardwood chips are prior to the refining step pretreated by impregnating them with an alkaline solution, and the essential feature of the invention is that in the pretreatment is used an alkali hydroxide solution with concentration in the range 0.1-0.5 M, and that the pretreated hardwood chips are mixed with the softwood chips, whereafter the mixture thus obtained is refined to groundwood pulp. The pretreatment solution is preferably a sodium hydroxide solution, and it may also contain sodium sulphite. The mixing of the pretreated hardwood chips and the softwood chips is most advantageously done so that the proportion of hardwood chips in the mixture is 30-60%. The binding strength and opacity of the groundwood pulp thus obtained are such that the pulp is appropri-ate e.g. for making printing paper.

Abstract Method and apparatus for injection compression molding of thermoplastic parts. A preferred apparatus (100) includes a platen assembly 106, a toggle clamp assembly 102, a screw injection assembly 101, a hydraulic system suitable for providing power to the toggle clamp assembly 102 and the screw injection assembly 101, and a control system 88 for operatively controlling the various hydraulic devices associated with the molding apparatus. The platen assembly 106 provides for a plurality of variable-volume mold cavities 7. In one embodiment, enlarged mold cavities 7 receive plasticized resin from the screw injection assembly 101, and compression of the injected resin is provided by the toggle clamp assembly 102. In another embodiment, the platen assembly 106 includes a floating die assembly wherein pressure created by injected resin causes die inserts 5 and support pillars 15 to slide relative to a molding plate 74. Compression in this embodiment is also preferably provided by the main toggle claimp assembly 102. Preferably, the toggle clamp assembly 102 provides multiple-stage compression of the resin to first redistribute the resin and vent the cavities and, second, compress the resin to compensate for cooling-induced shrinkage thereof. In the multiple cavity embodiment, because all cavities 7 are equally compressed simultaneously, control of the molding process and balancing of the mold are readily accomplished. The method and apparatus are particularly well suited for molding optical lenses and disks. Printed circuit substrates can also be molded thereby.
