Abstract: ELECTROMAGNETIC COUPLING DISC                 Abstract of the Disclosure The non-working face of a coupling disc (i.e., the armature or rotor) of an electromagnetic coupling such as a clutch or brake is formed with radially spaced rows of angularly spaced grooves separated by radially extending bridges.  The grooves terminate short of the working face of the disc and delineate magnetic poles in the disc.  In some embodiments, radially spaced rows of grooves also are formed in the working face of the disc.  In still other embodiments, excess metal resulting from rolling of the grooves in the non-working face of the disc is used to form integral locating flanges or the like adjacent the disc.

Abstract: ABSTRACT         With the article, smoking is simulated by inhalation of nicotine without the action of heat.  A carrier device (14), for example, a packing of spheres (20), for a nicotine preparation capable of volatilizing at room temperature is incorporated in a container (10) with air inlet (11) and air outlet (12).         The carrier device (14) forms a plurality of uninterrupted flow channels (21).  The nicotine preparation (e.g., pure nicotine) is applied on the free and nonabsorbent surface of the carrier as a thin layer (22) leaving the channels (21) open.         Glass or other sufficiently impervious, inert materials come into consideration as the material for the carrier device (14).  Various shapes of carrier devices are described.                               (Figure 1)

The closing lever (20) bears a follower roll (21) which is mounted so as to be freely rotatable and interacts with closing links (30, 30a, 30b). For locking the first gripper part (5) in the clamping position, a locking device (24, 25) is provided. To make possible a closing of the first gripper part (5) in any pivot position of the gripper (2) and with the gripper (2) moving in opposite directions (B, B'), the closing lever (20) together with the first gripper part (5) encloses an angle ( alpha ) which is smaller than 90 DEG . <IMAGE>

Granted: 1995-01-10
Abstract: ABSTRACT           A converter processes a digital video signal according to a known redundancy reducing algorithm executed on successive block for each frame or field, generating a transformed signal which is applied to a quantizer adapted to generate a quantized signal at preset transition levels on opposed sides of the zero, including the zero (...,-3,-2,-1 0, 1, 2, 3,...).  The quantized signal is processed by a processor, adapted to determine the block length and the consecutive zero sequences along a preset scanning order, and to output a symbolic signal constituted by symbols indicating the quanti-zation levels of the non null data, the zero sequences and a symbol indicating the block end.  The symbolic signal is applied to a variable length VLC encoder, adapted to encode data according to a preset designation law for generating a signal which is applied to a transmission buffer.  According to the invention, said quantized signal,  generated by the quantizer, further includes two ambiguous levels (x1 and x-1) at input values falling within respective preset intermediate ranges respectively between the zero level and the first positive level and between the zero level and the first negative level;  the processor transforms each of the ambi-guous levels respectively in a first positive level and first negative level if the preceding and subsequent input values are both non null and non ambiguous, and transforms the ambiguous level in zero level in all the other cases.
