Title: Utility hauling vehicle having four wheel drive
Inventor: SIMON MERLIN E
IPC: B62D61/10
Filed: 1987-04-15
Granted: 1991-08-06
Abstract: UTILITY HAULING VEHICLE HAVING FOUR WHEEL DRIVE  Abstract of the Disclosure A utility hauling vehicle includes at least one steerable wheel suspended from the forward end of a rigid frame of the vehicle and front and rear pairs of unsuspended drive wheels mounted to the rigid frame rearwardly of the steerable wheel. The front pair of drive wheels is differentially driven and the rear pair of drive wheels is respectively coupled for being driven in unison with the front pair of drive wheels.  A differential lock is provided for locking the rear pair of drive wheels and, hence, the front pair of drive wheels for rotation in unison.  The suspension for the steerable front wheel or wheels acts to lift the forward end of the frame to transfer weight to the rear pair of drive wheels.  Weight transfer can also be accomplished by mounting the front pair of drive wheels at a level above the rear pair of drive wheels.  The vehicle has a load bearing zone substantially within a vertical projection of the largest area occupied by the drive wheels.

Granted: 1992-04-14
Abstract: The invention relates to a method of manufacturing a curved automobile glass pane. The glass sheet heated in a continuous roller conveyor furnace to bending temperature, is picked up by a traveling suction device and transported to a curving station adjoining the furnace. In the curving station the glass sheet is deposited onto a curving device which is comprised of a curving-form frame and a curving form which form occupies the interior space of the frame. The suction device is withdrawn, and a hot gas stream is applied from above, which stream impinges on the glass sheet, whereby said sheet is forced against the curving device comprised of the curving-form frame and interior curving form. Then the glass sheet is lifted from the interior curving from by means of the curving-form frame which frame now serves as a support ring, and sheet is transported to the neighboring cooling station.

Title: Adhesively held spiral wound tampon and method of its formation
Inventor: STOKES BRUCE G
IPC: A61F13/22
Filed: 1988-05-16
Granted: 1992-06-09
Abstract: ABSTRACT     The invention is generally accomplished by providing a generally rectangular blank of absorbent material.  Adjacent one strip of the rectangular sheet is placed a generally continuous line of adhesive.  The rectangular blank is then wound and compressed to form a tampon.  As the tampon is compressed the adhesive fuses one end of the wound tampon.  The blank is provided with a string prior to winding that is also adhesively connected to the tampon.  As the tampon expands in the vagina it will open at the insertion end but not expand significantly at the withdrawal end.  Therefore this tampon is easier to withdraw but expands readily at the insertion end to prevent leakage.  The tampon also resists telescoping during withdrawal.

Title: Acoustic pyrometer
Inventor: NUSPL STEVEN P
IPC: G01K11/24
Filed: 1988-08-12
Granted: 1993-03-30
Abstract: ABSTRACT         An apparatus and method for measuring high temperatures in a boiler transmits pulses of acoustic waves from one side wall of the boiler to an opposite side wall thereof.   Acoustic noise within the boiler, as well as the transmitted pulses of acoustic  waves  are  received  at  the  opposite  side  of  the boiler.  The received signal  is digitized  and compared to a digitized sample of the pulses during a time period which is more than the maximum transit time for the pulses between the side walls.  A point of maximum correlation between the sample and the signal is taken as the arrival  time for the pulse and is used to calculate the transit time of the pulse across the boiler.  This transit  time is used in turn  to calculate the velocity of the pulses.  The temperature can then be calculated as a  function of  the  velocity,  the molecular  weight  of  the medium and the specific heat ratio of the medium.  Each pulse has a modulated frequency between 500 an 30000 Hz.
