A locking electrical plug has a casing from which there extends at least one prong containing a longitudinal slot within which there is pivotally disposed a locking hook with a hook portion projecting laterally from the slot. A spring loaded release button projects from the casing and is connected to the rear portion of the locking hook. A receptacle for the plug contains an aperture to receive the at least one prong, the aperture including a lateral enlargement to receive the projecting hook po...

The seating furniture comprises a seat part and a back part disconnectably connected thereto in condition for use and to allow the furniture to be packed more compactly by the manufacturer for shipment to the retailer with the back part disconnected from the seat part and overlying the seat part. The furniture may be either a club chair or sofa or a rester or a lounger. The hardware comprises a mounting member connected to one of said furniture parts slidably received in a slot or channel or pas...

A system for illuminating panels such as advertising display panels is provided. Such illuminated panels include at least one row of point light sources located substantially within the at least one illuminated frame member, a diffusion layer have a diffusion edge facing the at least one row of point light sources, a backscattering layer coupled to a back surface of the diffusion layer, and a dispersion layer coupled to a front surface of the diffusion layer. The diffusion layer has an edge with...

A computer-implemented method of testing a target system using a stimulus-response test. The method includes obtaining the responses of the target system at predefined monitoring times. Each time the response changes state, a clock is reset, and the elapsed duration is kept from the latest response state change. If the elapsed duration from the last response state change exceeds an expected duration before the next state change, a possible fault is deemed to exist.

A tone detector able to detect multicomponent tones for various tone formats is disclosed. An input signal is received and frequency and amplitude components, if any, of each sample of the incoming signal are estimated. In estimating the components, a current digit value is used to appropriately filter the input signal and estimate frequency and amplitude components. Using the component estimates, a new digit value is determined using a table in storage corresponding to the current tone format. ...

A power tool and accessories therefor including a variable speed motor for a mortiser, an integrated chisel positioning tool for positioning a chisel in a desired position, and an integrated tool sharpening device mounted directly on the power tool to permit ease and efficiency in the sharpening of tools. Additionally, an improved clamping arrangement is provided that permits firm clamping of a work piece without slippage. Greater flexibility in the hold down may be achieved by using arms for th...

The invention disclosed relates to fabricated rigid sheets profiled for engagement with adjacent similar sheets for assembly as a panel having sufficient rigidity to enable sufficiently large areas to be produced for the construction of van bodies, domestic and other building, caravans and road signs. Each sheet is of substantially rectangular shape with rearwardly extending flanges at each of the opposed longitudinal edges arranged supportingly to engage a corresponding flange of an adjacent si...

Novel 7-oxocephalosporins and a process for preparing them are disclosed. These compounds are useful intermediates in the preparation of other cephalosporins which have antibacterial activity.

An electrode for sensing signals such as electrocardiograph signals used with an electrolyte is formed from an electrically conductive but galvanicallly inactive material having a galvanically active conductive material at the electrolyte interface. Examples are described including a body formed from a plastic or other non-conductive binder rendered conductive by inclusion of finely divided conductive carbon and having one or more metal particles anchored to the surface of the body which contact...
