Abstract: SURFACE CASING STABILIZER AND HANGER  AND METHOD OF EMPLOYING 'THE SAME            ABSTRACT OF THE DISCLOSURE:     A two part,  sectioned tapered cylindrical hanger and stabilizer threaded on its inner periphery which threads are broken circumferentially by longitudinally extending  slots  defining  right  angle  edges  which frictionally grip an enclosed metal well surface casing section.   The cylindrical hanger sections are further slotted  on  their  outer  periphery  longitudinally  to facilitate lodging of the hanger in the casing conductor to  fixedly  locate  the upper end of the surface well casing  within  the  conductor  in  concentric  relation therewith.  The surface well casing extends the length of  the  hole,  and during the  installation procedure, concrete is forced downwardly through the center of the casing and caused to rise between the casing and the wall  of the bore hole to lock the lower end of the surface casing to the bore hole.  The vertical edges of the semi-circular hanger sections abut and are locked together  by  locking  bars  fitting  within  opposing recesses  within  the  upper  ends  of  the  semi-annular hanger sections.  T-bar handles threaded to the sections facilitate their transport and mounting to the upper end of the casing conducter.

Abstract: 17                48,283 ABSTRACT OF THE DISCLOSURE         A low current,  expulsion-type fuse is taught. The low current, expulsion-type fuse has a movable spring-biased rod which is capable of moving through a ferrule of the fuse to cause an unlatching operation.  The rod is maintained in a spring-loaded disposition by a tripping mechanism with a mechanical advantage of sufficient magni-tude to allow a relatively thin fuse strain element to maintain the rod in the spring-loaded disposition.  An eye hook extends from one end of the aforementioned rod and is captured by a spring-loaded lever during the manufacture of the fuse.  The spring loading on the lever is such that it will release the aforementioned eye to allow the rod biasing spring to move the rod unless the aforementioned lever is retained by a retaining member.  The retaining member operates through the aforementioned lever against the spring thereof.   It is maintained in the retaining disposition by the tensile force of the fuse strain ele-ment.  When the fuse element blows, the retaining member and lever are moved by the main fuse rod spring to release the captured eye portion of the fuse rod.

Abstract: 9D-DW-13583-Kiefer MICROPROCESSOR BASED CONTROL CIRCUIT FOR WASHING APPLIANCES WITH OVERFILL PROTECTION            ABSTRACT OF THE DISCLOSURE           A control circuit is disclosed for appliances such as dish-washers and clothes washers.  The control circuit employs a microprocessor programmed to respond to user selected options to determine the operating sequence of the appliance.  The control circuit includes an overfill system which permits the microprocessor to detect and identity a flood condition in response to a signal from a float assembly.  The flood signal causes the microprocessor to initiate a flood control routine which inter-rupts the normal operating cycle being executed, if any, and initiates and maintains operation of a drain cycle until the water returns to the normal level for a predetermined period of time.  The flood routine overrides all other program control thereby preventing any other machine function until the flood condition has been eliminated and there has been user interaction.  The user is advised of the flood condition via an alpha-numeric digital display on the appliance control panel.  The overfill system will be activated regardless of the operative state of the appli-ance.

Title: Vehicle seat belt retractor mechanism
Inventor: COLLINS ALFORD F
IPC: B60R22/48
Filed: 1980-04-14
Granted: 1982-07-06
Abstract: ABSTRACT A seat belt inhibitor system is designed to prevent a door mounted inertial seat belt retractor 14 from locking the seat belt webbing 13 whenever the door is opened.  The retractor pendulum 31, sensitive to acceleration, moves the locking bar 28 upward locking the retractor and prevents the belt webbing from paying out.  An electromagnet 36, when energized, attracts a leaf spring 37 extending from the locking bar inhibiting movement of the latter.  System inhibiting is initiated by closing either a door latch switch 42 or a door release handle switch 41.  At low accelerations (occurring while the door is being opened), the locking bar 28 is restrained by the electromagnet 36 through the leaf spring 37.  If the system should fail such that the electromagnet was energized while the door is closed, high acceleration of the pendulum would force the locking bar up, locking the retractor.  Deenergizing occurs normally whenever the door is closed.

Abstract: Abstract:     The invention relates to the making of sheet articles of non-conducting material for identification.  The article is marked by the incorporation therein of a small quantity of very thin conductive fibres capable of both absorbing and reflecting microwaves.  The part of the article con-taining the fibres is placed in the path of an unguided microwave beam and the excess microwave energy arrested over that reflected is measured.  An output signal is produced which is representative of the excess.  The output signal is characteristic of the fibres and can be used to authenticate the articles of non-conductive material, such as banknotes, passports and bonds, because the characteristic signal is very difficult to simulate by a counterfeiter.

Abstract: ABSTRACT OF THE DISCLOSURE    A valve opening control device for use with an internal combustion engine having cam-operated cylinder valves comprises a cam-like member having a cylindrical surface concentric with a shaft about which the member pivots, and a cam-like section extending tangentially therefrom.  The control device shaft is positioned parallel to and adjacent a rocker arm shaft or otherwise perpendi-cular to the axis of travel of the cylinder valve and/or the plane defined by such axis of travel and the plane of travel of a cylinder valve rocker arm for such valve.          The valve opening control device transmits an opening force from the rotating engine camshaft for a distance which is progressively proportional to the distance the valve lifter travels in response to the rotating engine camshaft.    The amount of pivotal displacement of the control device is regulated by a hydraulic valve lifter, the effective length thereof being regulated by fluid pressure such that a higher fluid pressure increases the effective length thereof, causing the cylinder valve to be open through a larger degree of camshaft rotation and for a greater maximum distance.  This fluid pressure is regulated indirectly by the relative position of the engine throttle, so that higher throttle settings increase the fluid pressure to the hydraulic valve lifter to cause the cylinder valve to be open a greater distance and for a longer period of time.

Abstract: Abstract of the Disclosure A process is described for preparing continuous strand mat which provides for more uniform density of the mat across the width of the surface on which it was prepared.  In a preferred embodiment gaseous fluid is directed to the mat edges to fold loose strands at the edges under the mat and to align the edges of the mat in a substantially straight line.  The gaseous fluid, preferably air, is directed at the conveyor surface on which the mat is formed against the flow of the mat on the con-veyor and in a downward direction so that portions of the mat at the sides are lifted by the air as the stray strands are folded under to form the straight edge.  Mainly however the invention provides the formation of an edge on a continuous strand mat having an already formed substantially straight edge, during a needle operation to minimize edge waste during needling.
