Title: Composite video signal with audio
Inventor: BOCOX RONALD R
IPC: H04N7/04
Filed: 1993-12-15
Abstract: Abstract of the Disclosure COMPOSITE VIDEO SIGNAL WITH AUDIO A method for inserting an audio signal into a composite video signal having A front porch, a back porch, a horizontal sync pulse with a leading edge, and a luminance portion to provide an audio-on-video signal, includes removing one or more video parts at least partially from the luminance portion, sampling one or more audio parts, biasing a zero magnitude of the audio parts to the midpoint of the maximum luminance magnitude, and placing the sampled parts at least partially within the luminance portion of the composite video signal to form the audio-on-video signal. The method for inserting also includes inserting audio parts into blanking parts that follow leading and trailing equalizing pulses; and the method for inserting further includes inserting audio parts into blanking portions of test signals that follow the trailing equalizing pulses. A method for separating an audio signal from the audio-on-video signal includes sampling an audio plus magnitude of the audio parts at least partially within the luminance portion, subtracting a bias magnitude to provide an audio sample magnitude, holding the audio sample magnitude, replacing the held audio sample magnitude with a successive audio sample magnitude to provide a stepped audio output, low pass filtering to smooth the stepped audio output and to prevent Nyquist problems, and high pass filtering to prevent noise when an audio sample magnitude  is held during a vertical sync pulse.

IPC: H02B1/052
Filed: 1992-02-12
Abstract: Electrical supply equipment comprises a circuit breaker comprising a housing (2) having generally flat, parallel side faces provided on the underside with a mounting recess (4), for mounting on a mounting rail of the conventional "top hat" section, comprising a base (7), spaced parallel flanges (8) extending from the base, and parallel outwardly extending flanges (9) which together provide a support surface which may be engaged by an underside of the recess (4). Extending from the underside of the circuit breaker at right angles to the plane of the base is a contact member (22).  A supply assembly (28) comprises an elongate housing (30) within which an elongate bus-bar (32) is located, the bus-bar being provided with spaced intervals with spring clips (34). The housing (30) comprises a cover (36), provided at spaced intervals, corresponding to the spacing between the spring clips (34), with apertures (38). A supporting assembly comprises end housings (150), onto which the ends of the mounting rail are press-fitted, the housing also providing a support for the supply assembly, so that the supply assembly extends alongside, and generally below the mounting rail. In the use of the invention, a circuit breaker may be mounted on the mounting rail, the contact member (22) thereof passing through one of the apertures (38) of the housing (30) into engagement with the bus-bar (32) being pressed into face-to-face contact therewith by one of the spring clips (34). Additionally, equipment other than circuit breakers may similarly be mounted on the mounting rail, for similar engagement with the bus-bar, and ancillary equipment which does not need to be connected to the bus-bar may be mounted on the mounting rail, and by virtue of the relative position between the mounting rail and the supply assembly, this may be accomplished without disturbance to the position of such ancillary equipment by the position of the bus-bar.

Title: An arrangement for painting an extended object moving continuously in its longitudinal direction
Inventor: LINDBLAD ANDERS
IPC: B05B13/02
Filed: 1992-09-09
Abstract: To obtain paint on all sides of a strip, painting must be performed in two stages since the strip must rest on a surface while being painted. This is avoided if moving strips are guided in a manner allowing them to be free from mechanical support from the start of painting until they have passed a drying unit (11), after which they can rest on a support surface without the paint being damaged.

Title: Multi- port oilfield liner connector
Inventor: HASSEN BARRY RICHARD
IPC: E21B21/10
Filed: 1994-08-31
Abstract: In the oil and gas  industry  ,  wellbores are now commonly drilled horizontally through the oil or gas bearing  reservoir  rock  .    It  is  common  to  equip ("complete") the producing section with a special pipe (called  a  liner)  which  facilitates  maintenance  or enhancement  of  productive  capacity  .     Since  the producing  section  is  so  long  (100 m  to  2000 m)  for horizontal wells in comparison to vertical wells (1 m to 20 m) , the conventional liner completion designs , which were primarily designed for vertical wells  ,are often prohibitively  expensive  for  horizontal  wells.     In response to this expense, many horizontal wells are left uncompleted  ("open  hole")  or  are  completed  with  a simplified  liner  design  ,  which  compromises  well performance .  This invention is a low cost ported liner design which enables the following:    Retrievability, reuse , clean outs of produced sand , hydraulic jetting of  multiple  simultaneous  "perforations"  ,  abrasive jetting  of  multiple  simultaneous  "perforations" limited   entry   stimulation   or   chemical soaks underbalanced  operations   ,   low  torque  and  drag installation . The invention is essentially a specialized hole located in the liner couplings .
