Abstract: ELECTRICAL CONNECTOR ATTACHABLE TO AN END PORTION OF A POWER CABLE                     ABSTRACT OF THE DISCLOSURE     An electrical connector having a tubular support through which a power cable extends, and a contact housing within which the cable is connected to male or female contacts.         The support and housing have mating quick threads facilitating their assembly after connection of the cable to the contacts.          A lock means on the support automatically responds to connection of the support and housing to each other, to prevent their accidental separation.  Normal operation of a cable clamping device on the support clamps and strain-relieves the cable within the support.  Deformation of the cable to offer strain relief acts upon the lock means to prevent its movement from the position in which it locks the housing and support against accidental separation.  A cable-clamping and strain-relieving device is disclosed, including a screw threadable laterally through an opening of a wiring device body into a power cable-receiving passage formed in the body.    A swiveled head on the screw bears against the insulation of the conductor. Through the provision of guide slots in the body in which the screw is mounted, the head is maintained against rotation during advancement of the screw and removal of the screw from the body is prevented.

Abstract: ABSTRACT OF THE DISCLOSURE            Aluminum diffusion can be effected from continuous coatings of leafing-type aluminum particles and such leafing coatings in very thin layers are more effective than coatings of non-leafing aluminum, with or without diffusion.  Other protective metals in flake or leaf form can be substituted for or added to the leafing aluminum.  This divisional application is particularly directed to diffusion masking wherein aluminum diffusion coatings are kept from undesired locations by covering those locations with an Ni3Al-type masking layer containing thermoplastic resin over which is applied a powdered nickel masking layer containing thermo-plastic resin.  On firing, this masking combination forms a strong shell that effectively masks without contaminating the surrounding coating pack.

Abstract: CASE II                  ABSTRACT OF THE DISCLOSURE          A speech recognition method for detecting and recognizing one or more keywords in a continuous audio signal is disclosed.          Each keyword is represented by a keyword template representing one or more target patterns, and each target pattern comprises statistics of each of at least one spectrum selected from plural short-term spectra generated according to a predetermined system for processing of the incoming audio.  The spectra are processed by a frequency equalization and normalizing method to enhance the separation between the spectral pattern classes during later analysis.  The processed audio spectra are grouped into spectral patterns, are transformed to reduce dimensionality of the patterns, and are compared by means of likelihood statistics with the target patterns of the keyword templates.   A concatenation technique employing a loosely set detection threshold makes it very unlikely that a correct pattern will be rejected.

Abstract: ABSTRACT OF THE INVENTION     This invention relates to severable connecting means for joining two components that allows a pre-determined amount of movement of the components towards each other and fails by twisting one component relative to the second component.  More particularly, the invention may be used as a two component guarantee seal adapted for twist removal by the end user.  A plastic guarantee seal is shown, comprising an upper portion, and a lower portion separated by an area of reduced strength, and includes stop means associated with the upper and lower portions.  These stop means impede axial movement be-tween the upper and lower portions.  The lower portion is adapted for securement to a container neck and the arrangement is such that the area of reduced strength fails by twisting the upper portion relative to the lower portion.  According to another aspect of the container, the lower portion of the cap has a lead in portion that is sized to loosely fit over the mouth of a container and assists in aligning the seal with the container neck, and provides a snug fit with the con-tainer neck after the seal has been applied to the container.  The unique design of the present system, presents a two piece guarantee seal which is not prone to flashing of material, and thus overcomes a common problem in prior art closures.
