Title: Automated test apparatus for use with multiple equipment
Inventor: KUMP DONALD
IPC: G01R31/00
Filed: 1987-05-13
Granted: 1991-09-03
Abstract: ABSTRACT OF THE DISCLOSURE      A number of standardized microprocessors are used as building blocks for gaining access and control to other standardized functional resource circuit units.          One of the microprocessors is selected by a main processing unit to capture the different functional resource circuit units needed to perform functions of a discrete test instrument.  To instruct the different resource circuit units to perform the needed functions, a program is downloaded from a mass memory by the microprocessor.  After having performed the necessary functions, the microprocessor releases the different functional resource circuit units, which - along with the microprocessor - would return to idle and await the next selection.

Inventor: THIBAULT MARC-ANDRE
IPC: F27D27/00

Granted: 1994-07-05
Abstract: ABSTRACT OF THE DISCLOSURE      The invention provides a new stirring apparatus for stirring the liquid metal contents of a furnace, particularily the shallow furnaces used in the processing of aluminum and its alloys.  The apparatus consists of a reservoir separate from the furnace of relatively large horizontal cross-section and volume, into which a vaccuum draws metal from the furnace through a nozzle, the metal then being returned by gas pressure forcibly into the furnace through the nozzle in the form of a horizontally directed jet.  The cycle is repeated at sufficiently close intervals to ensure that the furnace bath is quickly and effectively mixed.  The nozzle directs the molten metal entering the reservoir tangentially to swirl the metal and reduce the accumulation of dross.  The reservoir comprises a bottom static part including the nozzle and a readily removable top cover carrying heaters for heating the reservoir interior and the dross that deposits on the side wall to ease its removal.    The cover also carries level control electrodes, an observation port, inlet valve, etc. The reservoir sits on a load cell which is used for level control by weighing the reservoir, and also to detect undesired bubbling of the pressurizing gas into the metal; a pressure detector on the cover also detects variations in internal pressure caused by bubbling.  The cycles of vaccuum and pressure are controlled in a manner that maximizes the quantity of metal entering the reservoir, and thus used in the stirring.

Title: Method and apparatus for testing or exercising muscles of the lower trunk of the human body

Granted: 1992-03-24
Abstract: ABSTRACT OF DISCLOSURE      Methods and apparatus for exercising or testing the strength of muscles in the lower trunk of the human body.   The patient or exerciser  is  seated  with  his  pelvis  and  legs fixed against movement and with his head, arms and upper back fixed relative to a movement  arm which  extends above  the seat and is mounted for pivotal movement relative to  the seat  about a  horizontal axis.          While  the  movement  arm  is  in  a  predetermined position, the patient applies a force  through the  upper back  to the movement arm to stress the muscles of the lower trunk, and the strength of these  muscles  is  measured.   To  exercise  these  muscles, the movement  arm  is  moved  by  a  force  exerted by the upper back against a bias of  a resistance  weight to  lift the  weight, and then the force is released to lower the weight and the process is repeated.  A compound weight system is employed to  allow precise weight  adjustment  to  suit  the strength of the exerciser.  The movement arm including the  weight of  the exerciser  is balanced about  the  pivot  axis  by  means of counterweights including an adjustable counterweight.

Title: Salt water cell
Inventor: HASVOLD OISTEIN
IPC: H01M4/06
Filed: 1989-05-01
Granted: 1993-11-30
Abstract: Abstract The invention relates to primary galvanic cells (batteries) for use with salt water electrolytes, such as sea water.  The cell has a rod like anode made preferably of a magnesium alloy, and a cathode consisting of a stainless steel substrate coated with a catalyst for the reduction of oxygen. Examples of catalysts are cobalt spinel, cobalt nickel spinel and active carbon.  The cell can be constructed with the cathode coaxially arranged around a rod like anode.  The catalysts, which are the basis of this invention, have the ability to stimulate the reduction of oxygen that is dissolved in salt water.  This stimulation of oxygen reduction will lead to an increased voltage of the galvanic cell at a given current load and in addition contribute to an increased loadability when the catalytic active biofilm is lacking.
