Title: Magnetic coupling assembly for endoscope
Inventor: DEVINE ARTHUR JAMES
IPC: A61B1/00
Filed: 1997-11-26
Abstract: An endoscope coupler apparatus and method includes a sealed chamber and a lens assembly movable within the chamber for optically adjusting an image to be received by a video camera. The optical adjustment may be, for example, a focus adjustment or a zoom or orientation adjustment, etc. In a preferred embodiment, spaced permanent drive magnets located in an outer rotatable frame situated outside of the chamber are magnetically coupled with respective permanent driven magnets secured to an inner rotatable frame within the sealed chamber. The outer frame is rotatable but not longitudinally movable about the chamber and rotates the drive magnets and, therefore, the driven magnets. The inner frame is secured to a rotatable cylindrical housing which engages a lens assembly. Rotation of the driven magnets and the cylindrical housing moves the lens assembly longitudinally in response to rotation of an adjustment ring attached to the outer frame.

Inventor: SEECHARAN TONY
IPC: B28B19/00
Filed: 1998-07-08
Abstract: Methods and apparatus are disclosed for producing gypsum board having at least one facing sheet, a core of cementitious material such as low density gypsum, and an intermediate layer of bond promoting material, such as higher density gypsum located therebetween. The apparatus includes a foaming table having a transverse gap. The facing sheet travels along the forming table over the gap.

Title: Error correction of system transfer function by use of input compensation
Inventor: FARWELL WILLIAM D
IPC: H04L25/03
Filed: 1998-09-03
Abstract: A technique to modify the input data to any system so as  to cancel  errors  in the  transfer  function of  that system.  The system error response to each possible input amplitude transition is determined.  A compensating input sequence is calculated which compensates for this error. The error-correcting sequence is stored in memory for each possible  transition.    These  pattern  sequences  exactly cancel errors in the response to each of the possible, individual sample-to-sample transitions.  For each of any series of input data sample transitions, the appropriate correction sequence is recalled from memory.  The composite corrected input is the sum of Y correction sequences from Y preceding sample transitions.

Title: An intelligent dispensation control system for a vending apparatus
Inventor: ODEN KENNETH W
IPC: G07F9/00
Filed: 1990-08-17
Abstract: A vending apparatus ensures that the delay between a customer's selection of an article, and the dispensation of the selected article, is minimized, preferably to less than a predetermined delay, regardless of the point in a multi-article vending cycle. The reduced selection-dispensation delay is achieved through use of a "memory and learning" feature. The "memory and learning" feature is predicated on a recall and/or analysis of the relative times of occurrence of one or more previous dispensations, so that the apparatus' present position in the multi-article vending cycle is determined. The "memory and learning" feature allows the vending apparatus to anticipate how long the article dispensation mechanism should run after the present dispensation, to strategically poise the mechanism for a subsequent dispensation having an optimum selection-dispensation delay. Also disclosed are systems and methods for ensuring that articles are dispensed at a proper temperature, even after a "sold-out" condition is corrected; and for sounding an alarm if a person jars the vending apparatus in an attempt to improperly jar an article from the vending apparatus.

Title: Apparatus and process for removal of hydrogen sulfide
Inventor: MARKOWITZ JAMES P
IPC: B01J8/02
Filed: 1997-04-09
Abstract: An apparatus and process is provided for the removal of hydrogen sulfide from gases and for restoration of hydrogen sulfide removal capacity in nitrogen-treated carbonaceous chars which have become exhausted for hydrogen sulfide capacity when used for the removal of hydrogen sulfide from gas streams. The apparatus has a matrix of removable canisters which contain the nitrogen-treated carbonaceous chars.      This process entails directing the gas containing hydrogen sulfide through the canister, washing the spent carbonaceous char with water by flushing/ dynamic washing through the canister to remove the majority of the hydrogen sulfide reaction products. By the use of this process a significant proportion of the original hydrogen sulfide capacity of the nitrogen-treated carbonaceous char is recovered and the canisters can be recycled a large number of times.
