    Abstract: An apparatus for protecting a user's knee or other joint which comprises two generally semi-cylindrical rigid members each having semi-hemispherical overlapping portions and hingedly connected to allow a movement of the joint. Additional features of the protector include a replaceable inner pad, easily releasable and reusable hinges which provide the only attachment means for inner padding of the protector, replaceable outer attachment strips which may be made of varying materials which provide different adhesion properties, slightly elastic straps, and an attachment clip which adjustably attaches to one end of a strap and securely and releaseably attaches to a buckle located on a side edge of the rigid semi-cylindrical member.

    Abstract translation: 一种用于保护使用者的膝盖或其他接头的装置，其包括两个大致半圆柱形的刚性构件，每个刚性构件具有半半球重叠部分并且铰接地连接以允许接头的移动。 保护器的另外的特征包括可更换的内垫，易释放和可重复使用的铰链，其提供用于保护器的内部填充的唯一附接装置，可更换的外部附接条，其可以由提供不同粘合性质的变化材料制成，稍微弹性的带， 以及可调节地附接到带的一端并且可靠地并且可释放地附接到位于刚性半圆柱形构件的侧边缘上的带扣的附接夹。

    Abstract: Type A gelatin is modified by reaction at a pH of from 3 to 8.5 and temperature from 25 DEG to 90 DEG C. with sufficient polycarboxylic acid compound selected from succinic, maleic, phthalic, citraconic, itaconic, and aconitic anhydrides and succinyl and fumaryl chlorides, and mixtures thereof, to lower the isoelectric p point of said type A gelatin within the pH range of 4.0 to 5.5. Type B gelatin may be mixed with the type A gelatin during the reaction. The reaction mixture may contain 2 to 3% by weight of the type A gelatin of succinic anhydride or maleic anhydride, or 3.5 to 5% by weight of succinyl chloride. The type A gelatin may be deionized after or deanionized prior to the reaction. The modified type A gelatin may be added to a gelatin solution to stabilize the viscosity loss of the solution from prolonged heating at 60 DEG C., or may be used in the formation of a hard gelatin capsule or marshmallow.ALSO:Marshmallow formulations and hard gelatin capsules contain a type A gelatin modified by reaction at a pH of from 3 to 8.5 and temperature from 25 DEG to 90 DEG C. with sufficient polycarboxylic acid compound selected from succinic, maleic, phthalic, citraconic, itaconic and aconitic anhydrides and succinyl and fumaryl chlorides, and mixtures thereof, to lower the isoelectric point of said type A gelatin within the pH range of 4.0 to 5.5. Type B gelatin may be mixed with type A gelatin during the reaction. The type A gelatin may be deionized after or deanionized prior to the reaction. The modified type A gelatin may be mixed with conventional type A gelatin in the manufacture of capsules.
