Title: Method of formulating dairy cow rations based on carbohydrate regulation
Inventor: NOCEK JAMES E
IPC: A23K50/10
Filed: 1986-10-03
Granted: 1992-04-07
Abstract: Abstract Of The Disclosure A novel method of formulating dairy cow rations based on regulation of the content of non-structural carbohydrates and neutral detergent fiber in the total daily ration, including both forage and grain portions, is disclosed.          Feedstuffs analyzed to determine the percentages of non-structural carbohydrate and neutral detergent fiber contained thereby were fed in various proportions to test groups of cows under controlled conditions, and to commerical herds under actual field conditions to determine the effects, if any, on milk production by varying the proportion of the total daily ration constituted by non-structural carbohydrates.  Also, the proportion of non-structural carbohydrates to neutral detergent fiber in the ration was calculated and compared with milk production levels.  It was established that milk production was optimized when the total daily ration, including at least one grain and one forage, consists of between about 30% and 45% non-structural carbohydrates, depending upon forage type.  Furthermore, it was found that the ratio of non-structural carbohydrates to neutral detergent fiber bears a quadratic relation to milk yield and that the optimal response is achieved by maintaining the ratio within a range of about .9 to 1.2, the preferred ratio being about 1.05 (i.e., 1 part non-structural carbohy-drate  to 1.05 parts neutral detergent fiber).

Title: Multi-component, multi-segment, non-flexible boot for  mechanical joint
Inventor: HAZEBROOK DANIEL W
IPC: F16D3/20
Filed: 1987-02-23
Granted: 1995-07-11
Abstract: A sealing boot for sealing a power transmitting mechanical joint, especially a mechanical joint which is subject to angular articulation bet-ween its input shaft and output shaft.  The mechanical joint has an outer race which is a part of its output shaft, and the outer race has an external spherical surface.  The sealing boot has a segment which is made up of con-centric inner and outer non-flexible components which surrounds a portion of the outer race, and the inner component of the two-component segment sealingly engages the external spherical sealing surface of the outer race.  The two-component non-flexible segment of the boot and the outer race of the joint can be articulated relative to one another without breaking the seal therebetween.  In the preferred embodiment the remainder of the boot constitutes a non-pleated, funnel-shaped, non-flexible second boot segment, the enlarged end of which is generally spherically-shaped and is received in a spherical groove defined by the inner component and the outer component of the two-component non-flexible portion and the other end of which sealingly engages the input shaft of the mechanical joint.  A portion of the articula-tion required during normal driving is obtained by the movement of the enlarged end of the second boot segment in the spherical groove defined by the inner and outer components of the two-component boot segment. Additional articulation is provided by the spherical sliding of the two-component boot segment on the spherical surface of the outer race after the second boot segment bottoms in the spherical groove of the two-component boot segment.

Title: Lubricating oil composition
Inventor: WATANABE NOBORU
IPC: C10N20/00
Filed: 1987-03-31
Granted: 1990-12-04
Abstract: ABSTRACT OF THE DISCLOSURE      The lubricating oil composition comprises 15-85 parts by weight of a poly-.alpha.-olefin having a kinematic viscosity of 1.5-150 centistokes at 100°C and 85-15 parts by weight of a mineral oil having a kinematic viscosity of 2-50 centistokes at 100°C and a pour point of -35°C or below.  By virtue of the admixture of the mineral oil, the lubricant oil composition is much more inexpensive than the poly-.alpha.-olefin per se while retaining the excellent properties inherent in the poly-.alpha.-olefins such as the stability against oxidation, low-temperature performance, high-temperature cleanness and friction characteristics with wet clutches.
