Abstract: The specification relates to a noise-reduced mixing valve comprising a valve body (1) and, located in the control part within said body, ceramic disks (2, 3). The fixed disk (2) is penetrated by inlet apertures (7) for hot and cold water and moreover penetrated by an outlet aperture (8) for the mixed water. In the movable disk (3) there is an aperture acting together with the apertures in the fixed disk (2) to control the flows of hot and cold water and it acts together with a plastics piece (4) joined to it to form a mixing space (11) for the water. In order to improve the noise reduction and to achieve an even flow of water a flow guide piece (10) forming a curved guide surface (13) between the inlet apertures (7) and the outlet aperture (8) is disposed in the bottom part of the mixing space (11). The guide piece can be attached e.g. to the fixed disk (2) by means of a projection (12) extending into the outlet aperture (8) of the disk, or alternatively to the movable disk (3) by projections extending along the walls of the mixing space and engaging in recesses in the movable disk.

Abstract: At each station of the overhead cable transport installation the vehicles which have been released or unclamped from the conveying cable are decelerated or accelerated by pneumatic wheels. Between the V-belt drive and the hub of each pneumatic wheel there is arranged a free-wheeling clutch or slip coupling equipped with a pre-biased restoring or return spring. The free-wheeling clutch transmits in one direction the torque or rotational moment from the V-belt drive to the pneumatic wheel without play. In the opposite direction such free-wheeling clutch rotates against the restoring moment of the pre-biased restoring spring. As a result there is eliminated the slip and the resultant wear of the pneumatic wheels upon the friction plate with which they come into contact during such time in which two neighboring pneumatic wheels engage with the friction plate.

Title: Echo canceller with means for determining filter coefficients from autocorrelation and cross-correlation coefficients
Inventor: TAGUCHI TETSU
IPC: H04B3/23
Filed: 1989-12-01
Granted: 1993-07-06
Abstract: Abstract of the Disclosure:         In a data transmission system where a first signal partially leaks as an echo from a first transmission line to  a second transmission line through a hybrid circuit to form a mixed signal of the echo and a second signal on the second transmission line, an echo canceller is used for cancelling the echo by producing an echo replica at a transversal filter according to filter coefficients and subtracting the echo replica from the mixed signal.  In order to reliably generate the filter coefficient for a reduced time duration, a series of autocorrelation coefficients of the first signal and a series of cross-correlation coefficients between the first and the mixed signals are calculated at calculators and the filter coefficients are determined from both of the autocorrelation and the cross-correlation coefficient series at a coefficient determining circuit.  The coefficient determining circuit may be an arithmetic circuit for solving simultaneous linear equations.  Another circuit for determining the filter coefficients may be a circuit where a first filter coefficient is determined by detecting the maximum value and the corresponding delay time from the series of cross-correlation coefficients, making a fresh series of cross-correlation coefficients with reference to the maximum values, the delay time and (Abstract of the Disclosure continued) the first filter coefficient, then, determining a second filter coefficient from the fresh series.  Then, filter coefficients are determined by repetition of the similar operation.

Title: Power tongs
Inventor: FEIGEL KURT R JR
IPC: E21B19/16
Filed: 1990-05-08
Granted: 2001-07-03
Abstract: A power tong includes a frame having arcuate front portions defining a throat, a cage plate assembly mounted on the frame for rotation about a central axis and a ring gear also mounted on the frame for rotation about the axis. The throat receives the pipe to be rotated, and the cage plate and ring gear include die means for gripping the pipe. The ring gear and cage plate cooperate to rotate the pipe within the frame, which remains stationary. The design of the power tong is such that the arcuate front portions of the frame are more flexible than the cage plate assembly and ring gear combination, and strain is primarily taken up by the ring gear and cage plate. In addition, the cage plate and ring gear are sufficiently rigid such that they may not flex to a degree that teeth on the ring gear flex more than the backlash in the gear train that drives the ring gear.      Finally, the ring gear includes offset cam surfaces, which help to ensure that the pipe is centrally located within the ring gear, the cam surfaces having identical elliptical sections.

Granted: 1997-01-14
Abstract: The posture board according to the present invention is contoured to a spinal mating shape.  The board comprises an upper back supporting portion having a leading edge and a lower back supporting portion terminating in a trailing edge.  The board has a longitudinally extending sine wave configuration with an up curve at the lower back supporting portion.  The board further has a side to side concave curvature defining a trough like center region and upwardly turned outside edges.  The center region along at least part of the upper back supporting portion and at the trailing edge is in contact with the supporting surface on which the posture board is used.  The up curve defines a gap beneath the center region along the lower back supporting portion and the supporting surface.  The outside edges of the board are more flexible than the center region to allow some edge flattening while the center region is much less flexible to prevent lengthwise full flattening of the board at the center region under weight of a user such that the board provides vibratory feedback responsive to body vibrations given off by the user.
