Abstract: A belt conveyor (10) has vertically spaced, oppositely moving, upper (14) and lower (18) load carrying runs having entrance and exit ends (16, 17; 20, 21). A first series of rollers disposed between die cut end (17) of the upper run (14) and the entrance end (20) of the lower run (18) direct the belt downwardly, around a first drive assembly (26) toward the entrance end (20) of the lower run (18) along a first depressed section (37) of belt travel below the level of the lower run (18) and upwardly to the entrance end (20) of the lower run (18) from a static takeup (38) installed below the lower run. A second series of rollers disposed between the exit end (21) of the lower run (18) and the entrance end (16) of the upper run (14) direct the belt downwardly from the lower run exit end (21) along a second depressed section (44) of belt travel below the level of the lower run around a second drive assembly (48) and upwardly to the entrance end (16) of the upper run (14). Lower run feed (105, 106, 107) and take-away (113, 114, 115) conveyors, respectively arranged above the first (37) and second (44) depressed sections of belt travel, converge into and diverge from alignment with the lower run entrance (20) and exit (21) ends for the in-line transfer of articles to and from the lower run (18).  Upper run feed (120) and take-away (122) conveyors an aligned longitudinally with the upper run entrance and exit ends.

Title: Pivot point contact with scrubbing action switch
Inventor: STRINGWELL RODERICK WILLIAM
IPC: H01H1/12
Filed: 1995-05-17
Abstract: An electrical switch with pivot point wiping contact assemblies for scrubbing debris from electrical contact mating surfaces. For each electrical contact within the switch there is a battery rivet having a convex mating surface and a contact rivet which also has a convex mating surface. The contact rivet is mounted onto one end of a resilient wiping arm consisting of conductive material. The other end of the wiping arm is pivotally mounted within the slot of a pocket contact consisting of conductive material. Also connected to the wiping arm is a contact driver which abuts a manually moveable pin. Therefore, by moving the pin the resilient wiping arm rubs the contact rivet mating surface onto the battery rivet mating surface while making an electrical connection.

Title: Method and apparatus for automatically adapting the amount of warping in a system transmitting information through a non-linear channel
Inventor: BETTS WILLIAM LEWIS
IPC: H04L27/34
Filed: 1995-07-24
Abstract: The present invention discloses an improvement over existing techniques for transmitting data over voice-band telephone channels by automatically adapting the amount of warping or compression that is applied to a sequence of signal points.  A sequence of warped signal points, each of which is related to a respective signal point of a predetermined base constellation according to a warp function, is received in a decoder via a transmission channel having a non-linear component.  After each of the received signal points is unwarped using substantially an inverse of the warp function, the average dispersions of the received inner and outer signal points about corresponding sequences of expected signal points are calculated.  The difference between the average dispersion of the inner and outer points is then computed and used to update the amount of warping or compression in order to further minimize the effects of the channel non-linearity. The desired amount of warping is communicated to the transmitting encoder.

IPC: A61B17/00
Filed: 1994-04-21
Abstract: A surgical cutting instrument (10) includes an outer tubular member (13), or cannula, sized for percutaneous insertion into an anatomical space. The outer tubular member has a cutting opening (14) at its blunt-tipped distal end (15). The proximal end is supported by a hand piece (11). A cutting member (20) includes a tubular member having a cutting head (43) portion at its distal end and a body portion (44) extending therefrom to the hand piece (11). A hinge (41) is integrally formed in the tubular cannula to connect the cutting head (43) portion with the body portion (44), to permit pivoting of the cutting head portion (43) relative to the body portion. As the cutting member (20) is reciprocated within the outer cannula (13), the cutting edge (22) contacts tissue drawn into the cutting opening (14). Resistance from the tissue causes the cutting head to pivot about the hinge to form an essentially zero clearance between the cutting head and the cutting opening in the outer cannula.

Patent CA-2167967-A1 (CA)
Inventor: ALLEN JONATHAN BRANDON
IPC: G10L19/035
Filed: 1996-01-24
Abstract: A new technique for the determination  of the masking effect of an audio signal is employed to provide transparent compression of an audio signal at greatly reduced bit rates. The new technique employs the results of recent research into the psycho-physics of noise masking in the human auditory system. This research suggests that noise masking is a function of the uncertainty in loudness as perceived by the brain. Measures of loudness uncertainty are employed to determine the degree to which audio signals are "tone-like" (or "noise-like"). The degree of tone-likeness, referred to as "tonality," is used to determine masking thresholds for use in the compression of audio signals. Tonality, computed in accordance with the present invention, is used in conventional and new arrangements to achieve compression of audio signals.
