Title: Production of gelatin from fish skin
Inventor: SHIYUROMO GUROSUMAN
IPC: C09H3/02
Filed: 1989-12-28
Abstract: A process for the production of gelatin from fish skins comprises the steps of: (a) cleaning the skins in order to remove therefrom substantially all superfluous material; (b) treating with dilute aqueous alkali; (c) washing with water until the washing water is substantially neutral; (d) treating with dilute aqueous mineral acid; (e) washing with water until the washing water is substantially neutral; (f) treating with dilute aqueous citric acid and/or another suitable organic acid; (g) washing with water until the washing water is substantially neutral; and (h) extracting with water at elevated temperatures not above about 55<o>C, the washed citric/other organic acid-treated skins. In practice, the present process employs much lower temperatures than known heretofore for the treatment steps, which results in a high quality product (e.g. absence of a fishy smell), compared with the prior art.

Abstract: PROBLEM TO BE SOLVED: To keep a displayed message to be easy to see, to make a displayed message easy to see and to eliminate the sense of incongruity by fixing a chain to the left and lower part of a main body. SOLUTION: A chain fitting 2 and the chain 3 are fixed at the left and lower part of the main body. Whichever of left/lower, left/upper, right/lower and right/upper parts of the main body 1 a user holds to use, the chain 3 is not a hindrance to hold the main body 1. Thus the message on a display part 4 is easily kept easy to see, the message is easy to see and the sense of incongruity is eliminated. As the left and lower part is the nearest from the left chest pocket of a human body where one end of the chain 3 is fitted to at the time of reading the characters on the display 4, the length of the chain 3 is most effectively used when the chain 3 is fitted there. Namely a movable range is the largest at this position.  In addition even in the state of extending the chain 3, an angular degree formed by the pocket beeper main body 1 and the chain 3 is an obtuse angle and in near the most stable state at the time of extending so that the chain 3 is stable and leverage principle is difficult to accept. Thus the angle of the pocket beeper main body 1 is easily adjusted.
