Granted: 2001-06-12
Abstract: A wiping device for the plate cylinder of an intaglio printing machine has a trough (4), and a wiping cylinder (2) which is mounted in mutually-opposite side walls of the trough. The trough is itself mounted tiltably about a pivot axis (6) lying at least approximately in that plane (T') which passes through the axis of rotation of the wiping cylinder and which is parallel to the tangential plane (T) of the wiping cylinder (2) and plate cylinder (1) passing through the point of contact between the two cylinders. The pressing force with which the wiping cylinder (2) bears against the plate cylinder (1) can be set and regulated during the printing operation by means of an adjusting device (11, 12, 13) by correspondingly tilting the trough together with the wiping cylinder about its pivot axis (6).

Title: Variable vacuum attachment for hair grooming clippers
Inventor: ROMANI R MARLENE
IPC: B26B19/24
Filed: 1991-09-30
Granted: 1996-02-13
Abstract: A suction attachment for a hair grooming clipper includes a suction head having a vacuum relief port and a  flexible  sealing  lid  for  covering the  port.   The relief port communicates between an internal air flow passage in the suction head and the exterior of the suction head.  The sealing lid is movable by a user's finger to regulate the degree of relief of the vacuum provided by  the port.   The  suction head has  a  flow constriction  defined  in  the air  flow  passage  midway between a front inlet and a rear outlet and proximate the location of the relief port such that regulation of vacuum relief occurs at the region of the passage where the air pressure is highest and air velocity is lowest. Also,  a  hollow  tubular  extension  at  one  end  can  be inserted in the relief port when the port is completely open  to  prevent  clogging  of  the  open  port  by  hair entering the port from the exterior of the suction head.

Title: Method and apparatus for clarifying liquid using a pulsating sludge bed and part of concentrated sludge
Inventor: BALLARD P TEMPLE
IPC: B01D21/00
Filed: 1992-02-18
Granted: 1999-02-16
Abstract: There is disclosed a pulsating sludge bed clarifier especially for the treatment of low turbidity waters, which uses incline plates in the sludge bed and some recirculated sludge.   The clarification is greatly enhanced by recirculating a relatively small part of the sludge concentrate to a reactor chamber used for the premixing of water to be treated and the coagulant.  The small amount of recirculated sludge cuts down significantly on the polymer flocculant, which is the most expensive chemical in the process that is required to be used, and can also serve to improve the adsorption of colors and similar materials,  increase the density of the sludge blanket, and improve the rate of throughput of the system.

Title: Carrier recovery control with sequential fec sync detection and frame sync detection
Inventor: NAWATA HIZURU
IPC: H04L27/227
Filed: 1992-03-19
Granted: 1997-12-30
Abstract: At the transmit end of a communications system, a convolutional code of a multiplex of an information-bearing signal and a unique word is modulated upon a transmitted carrier.  At the receive end, the transmitted carrier is demodulated with a local carrier to detect the convolutional code. The error rate of a decoded version of the convolutional code is determined, and an out-of-FEC-sync signal is produced when the error rate is higher than a threshold value.  Unique words are detected from the decoded signal and counted during a prescribed time interval to produce an out-of-frame-sync signal when the count falls below a threshold.  The frequency of the local carrier is swept in the presence of the out-of-FEC-sync signal.  When this signal ceases to exist, a timeout period is set, and the local carrier frequency is swept again when the timeout period expires during the presence of the out-of-frame-sync signal.
