Title: Dual rate leaf spring construction
Inventor: NICKEL HERBERT W
IPC: B60G11/10
Filed: 1986-09-03
Granted: 1990-11-27
Abstract: DUAL RATE LEAF SPRING CONSTRUCTION     Abstract of the Disclosure A dual rate leaf spring construction includ-ing a main leaf spring, preferably formed of fiber reinforced resin, and having a central section adapted to be connected to an axle of a vehicle and having a pair of ends to be connected to the frame of the vehicle.  A secondary leaf spring, having a substanti-ally shorter length than the main leaf spring, is secured beneath and parallel to the main leaf spring, and an elastomeric pad is mounted on each end of the secondary spring.  The pads have upwardly facing round-ed heads that are spaced out of contact with the lower surface of the main spring under normal load condi-tions.  Under heavy load conditions, the main spring will deflect downwardly into contact with the pads to thereby enable the secondary spring to carry a portion of the load.

Title: Method of controlling strip crown in planetary rolling
Inventor: MIURA RYOZO
IPC: B21B1/02
Filed: 1987-09-16
Granted: 1992-06-09
Abstract: Abstract of the Disclosure Disclosed is a method of controlling a strip crown in planetary rolling in a planetary mill line.  A slab of a metal is rolled using a shaped feeding roll or rolls before passing between planetary rolls to shape the profile of the slab in the widthwise direction of the slab so that the shaped slab has a flat central portion, opposite ends thicker than the central portion and side portions thinner than the central portion between the central portion and the side ends.  At least one of a pair of the feeding rolls adjacent to the planetary rolls has a roll crown including (i) a central region flat or curved for correcting bend of the feeding roll, (ii) a side end having a diameter smaller than that of the central region, (iii) an enlarged side portion spaced from the side end by a distance determined by a roll gap between the central regions of the pair of feeding rolls and having a diameter larger than that of the central region by 0.1 - 1 % and (iv) a tapered side region between the enlarged side portion and the side end.  Then the slab is further rolled by planetary rolls.  By this way, a planetary-rolled strip having a substantially flat strip crown is produced.

Granted: 1992-04-21
Abstract: HIGH SPEED DC MOTOR          ABSTRACT OF THE DISCLOSURE The stator electromagnets (80', 82', 84', 86', 88', 90') face inward about the rotor cavity (12) of the motor. Spaced horseshoe magnets (70) with spaced apart,opposite poles face outward about the periphery (22) of the rotor (20). The stator electromagnets face in two arrays. Each array is aligned with one pole of the rotor set of horseshoe magnets and has a pulling electromagnet (80' or 86') of a pole opposite to the pole of the rotor magnet. Each array also includes two pushing electromagnets (82', 84' or 88', 90') circumferentially offset from the pulling electromagnet, which are of a magnetic pole the same as the pole of the rotor magnet. Optical sensors (173, 175), which are axially aligned with the electro-magnets, sense the position of rotor with regard to points on the stator. Switches on a circuit card associated with each array of electromagnets connect to the corresponding optical sensor for alternatively passing or blocking current to the electromagnets. The switches energize and de-energize the pulling and pushing electromagnet when the rotor magnet passes an adjacent, preceding, pulling electro-magnets when the rotor magnet passes a predetermined position.

Title: Test tube holder
Inventor: MAWHIRT JAMES A
IPC: B01L9/06
Filed: 1988-05-10
Granted: 1991-04-02
Abstract: ABSTRACT OF THE DISCLOSURE       The test tube holder includes an elongated tubular member which supports a pivot member thereby rendering the tubular member and pivot member relatively pivotable with respect to each other.  Latch members provided on the tubular member and pivot member are engagable with complementary shaped latch members of other test tube holders to form a linkage.  The pivotal relationship between the tubular member and the pivot member permit pivotal movement of one test tube holder with respect to the longitudinal axis of another test tube holder.  A pivotal connection between the latch members of adjacent test tube holders also permits tilting of one test tube holder with respect to another test tube holder in the linkage,  An adapter member for holding test tubes is insertable in the tubular member and pivot member assembly.  The adapter member accommodates one size test tube and can be interchanged with another adapter member that accommodates another size test tube.  Thus, the linkage of test tube holders can include test tubes of different size.  The relative pivotal movement between test tub  holders in the linkage permits stacking of the linkage in a fan-fold arrangement.  The tilting movement between test tube holders in a linkage permits mixing of the contents of a test tube or a group of test tubes independent of all others in the linkage before a sample is tested.  Under this arrangement, a linkage of test tubes of unlimited length can be provided.
