Inventor: FREDERICK THOMAS R
IPC: F16K37/00
Filed: 1992-12-15
Abstract: An electro hydraulic servo valve has a pair of oppositely polarized magnets mounted in the surface of the spool of the valve to be controlled. A Hall effect sensor is  mounted  in  the  housing  adjacent  the  magnets  to precisely measure the position of the spool relative to the housing.  The magnets and transducer are mounted on the longitudinal centerline of the spool to eliminate the spurious signals, due to temperature, vibrations, shock, hydraulic supply pressure and back pressure.  The strength and spacing of the magnets and air gap are chosen to provide  a  linear  output  signal  over  the  range  of displacement  desired  and to  provide  the  accuracy  of location necessary for the particular configuration.

Title: Neural network system using spectral analysis for identification of complex organic structures
Inventor: MEYER BERND J
IPC: G06N3/00
Filed: 1991-07-29
Abstract: Apparatus and processes for recognizing and identifying materials. Characteristic spectra are obtained for the materials via spectroscopy techniques including nuclear magnetic resonance spectroscopy, infrared absorption analysis, x-ray analysis, mass spectroscopy and gas chromatography. Desired portions of the spectra may be selected and then placed in proper form and format for presentation to a number of input layer neurons in an offline neural network. The network is first trained according to a predetermined training process; it may then be employed to identify particular materials. Such apparatus and processes are particularly useful for recognizing and identifying organic compounds such as complex carbohydrates, whose spectra conventionally require a high level of training and many hours of hard work to identify, and are frequently indistinguishable from one another by human interpretation.

Title: A method in ozone bleaching of pulp
Inventor: BRANNLAND ROLF C A
IPC: D21C11/00
Filed: 1992-09-16
Abstract: When closing the process of manufacturing cellulose pulp of high brightness, i.e. including the recovery of essentially all waste liquor, there is an untenable enrichment of certain basic elements, such as sodium and sulphur. The present invention provides a partial solution to this problem and is concerned with a method in bleaching with ozone lignocellulosic material (cellulose pulp) which has been at least partially manufactured chemically, in the presence of water at a degree of acidity, expressed as pH, of 2-5. The method is characterized in that the acidity is maintained during the ozone bleaching process by adding a sulphuric acid solution or an acid sodium sulphate solution produced by electrolysis (or electrodialysis) of an essentially neutral sodium sulphate solution obtained by recycling chemicals in a system to which rest solution (waste liquor) from the ozone bleaching process is added.

Title: Method and apparatus for cleaning paint roller pads
Inventor: CLARK WILLIAM
IPC: B05C21/00
Filed: 1994-04-11
Abstract: It is common practice to clean paint roller pads by submerging the pads in a solvent bath. Sludge build up in the bath, however, renders this method less than desirable. In addition contact with the solvent can lead to irritating skin rashes. A method and device to alleviate these prob-lems is comprised of a raised grill like base upon which is mounted a plurality of upright posts, each post of a diameter sufficient to form a sliding fit to the bore of a typical roller pad. The base and posts are immersed in a solvent bath and the roller pads transferred to the upright posts and left to soak. Solids particles are dissolved of the pad, fall through the grill structure of the base and accumulate as sludge in the bottom of the bath. Removal of the cleansed pads is accomplished by inserting the working end of a convention pad spinner into the pad bore and pulling the pad off of the upright post. No skin contact with the solvent is necessary.
