Title: Building foundation, floor assembly and method of installation thereof
Inventor: FEARN RICHARD N
IPC: E04B5/48
Filed: 1991-02-22
Abstract: BUILDING FOUNDATION, FLOOR ASSEMBLY AND METHOD OF INSTALLATION THEREOF            ABSTRACT OF THE DISCLOSURE           The   invention  reduces   considerably   on-site labour costs for installing a foundation and a building floor.   Accuracy is improved by pre-fabricating a  floor assembly  prior  to  installation on site.   The  invention includes placing a plurality of temporary supports on the site  surface,  accurately locating the floor assembly on the  supports,  and providing a  space  between  the  floor assembly  and  the  surface.   Forms  are  located  on  the surface generally below the floor assembly.  Concrete is poured to occupy space between at  least the  form,  the surface and a portion of the floor assembly so that, after the concrete  is  set,  the  supports  are removed and the floor assembly is supported by the concrete.   The floor assembly comprises upper and lower skins, with perimeter webs connecting the skins together adjacent peripheries of the skins to form a plenum chamber between the skins and the webs.   Services  and  air  can  be  supplied  from  the plenum chamber.            B182:662.37

Title: Non-intrusive liquid flow meter for liquid component of two phase flow based on solid or fluid borne sound
Inventor: CODY GEORGE D
IPC: G01F1/66
Filed: 1992-06-16
Abstract: The present invention is a method for measuring the mass flow rate of liquid flow exiting a two phase (gas/liquid) feed nozzle. The method includes determining the Power Spectral Density from the output of a vibrational sensor (accelerometer or dynamic pressure sensor) in close proximity to the nozzle or in contact with the fluid within the nozzle in a frequency band that includes resonant peaks whose magni-tude or area is strongly dependent on the mass flow rate of the liquid and which increases as the flow increases. Measurement of the area of the resonant peaks or of a band of frequencies that includes them can be correlated with the liquid flow and is insensitive to the gas flow.

Title: Directional drilling tool
Inventor: SCHOEFFLER WILLIAM N
IPC: E21B23/04
Filed: 1992-06-16
Abstract: DIRECTIONAL DRILLING TOOL                    ABSTRACT OF THE DISCLOSURE       A  fluid  powered  incremental  stepping  motor  arranged to serve as a length of pipe string has a body that includes an arbor end with an arbor of reduced diameter extending into  a  bore  of  a  housing  end  bearingly  supported  for rotation about the-arbor.  An annular space between arbor and housing contains a piston rotationally secured to the arbor for limited axial movement. The piston operates within the bore as a power cylinder and carries a flow resistor. Fluid  channels  extend  through  the body  to  accept  fluid flow  down  the  pipe  string.  Fluid  flow urges  the  piston downward and a spring urges it upward.  Cams on each end of the piston and mating cams in the housing bore engage at the upward and at the downward extreme of piston travel and  at  each  engagement  impart  an  increment  of  rotation of  the  housing  relative  to  the  arbor at  each  excursion of the piston.  Increasing fluid flow down the pipe string and  then  decreasing  the  flow  causes  the  piston  to reciprocate  at  each  flow  rate  change  cycle. The housing then is caused to rotate in steps as long as the flow rate cycling continues.

Title: Diagnosis of iddm with a panel of immunoreagents
Inventor: RABIN DANIEL U
IPC: G01N33/573
Filed: 1993-04-30
Abstract: ABSTRACT OF THE DISCLOSURE      Diagnosis of insulin-dependent (Type I) diabetes mellitus (IDDM) by contacting a blood sample from a patient with an immunoreagent comprising epitopes of two or more of glutamic acid decarboxylase (GAD) and the pancreatic islet cell antigens referred to as ICA512 and ICA12.  Binding of antibodies present in the blood sample with one or more of such epitopes correlates with IDDM or a potential for developing IDDM.  In clinical testing, about 80 percent of sera from newly diagnosed IDDM patients react positively with at least one epitope in a GAD/ICA512 panel. Reactivity with the GAD/ICA512/ICA12 panel is between about 80 and 90 percent.  The method is useful in screening patients for pre-IDDM, for distinguishing IDDM from Type II diabetes, and for monitoring therapy.
