Title: Improved process of producing brown rice with longer shelf-life
Inventor: GARCIA ROSEMARIE G
Filed: 2017-08-09
Abstract: The utility model relates to an improved process for the production of stabilized brown rice with longer shelf life. The paddy rice was converted into a stabilized brown rice/unpolished rice by application of combined moist and dry heat treatment using saturated steaming and fluidized bed drying, respectively, for a certain period of time and temperature to inactivate the inherent enzymes present in the bran layer of brown rice/unpolished rice. These enzymes are the primary reason for its short shelf-life (1 - 3 months) of brown rice. It converts the oil/fat which is also present in the bran into free fatty acids. These free fatty acids are susceptible to oxidation that produces peroxides and aldehydes which is associated with the rancid odor of brown rice/unpolished rice.

Abstract: Il presente modello ha per oggetto notevoli innovazioni nei lampioni, nei lampioni solari e nei sistemi di illuminazione stradale e pubblica in genere.Trattasi di lampione stradale alimentato da energia solare tramite la conversione fotovoltaica. Come è noto i punti luce nell'illuminazione stradale e pubblica in genere presentano sempre il doppio vincolo di avere il sostegno del corpo illuminante fisso con blocco di fondazione in calcestruzzo interrato (o con ancoraggio a muro) e obbligati ad un punto di alimentazione elettrica anch'esso fisso.Il lampione fotovoltaico che si propone presenta la soluzione per il doppio vincolo di cui sopra. Essendo esso ad alimentazione solare, è praticamente indipendente dall'allaccio alla rete ed inoltre avendo un basamento in cemento armato autoportante semplicemente poggiato è trasportabile. Inoltre esso è totalmente smontabile e rimontabile per facilitarne il trasporto senza impiego di personale specializzato.Il lampione solare mobile è particolarmente adatto per l'illuminazione pubblica in zone sprovviste di energia elettrica.In quanto trasportabile è in grado di risolvere problemi momentanei di illuminazione (zone periferiche, presidi isolati, campi, ecc.).La sua versatilità ne permette l'uso anche in caso di catastrofi naturali, dove si presenta come prima priorità il ripristino dell'illuminazione stradale.

Title: Improvements in the manufacture of articles of rigid material and rubber
IPC: B29C65/64
Filed: 1938-01-04
Abstract: 499,433. Resilient mountings. METALASTIK, Ltd., and GOLDSCHMIDT, M. Jan. 4, 1938, No. 185. [Class 108 (iii)] A method of manufacturing articles formed partly of a rigid material and partly of rubber permanently bonded together consists in assembling a rubber block or part between the rigid parts of similar contour and uniting the parts by bolts or rivets to apply a stress upon the rubber part therebetween equal to the pressure necessary to achieve permanent bonding of the rubber to the metal, the coacting surfaces of the rubber and metal parts being treated to permit of the bonding. As shown applied to a crank-shaft damper pairs of plates 2, 3, 4 of metal, artificial resin, &c. are provided with rubber inserts 5 between plates 2, 3 and the opposite pairs of plates 3, 4 are secured together by bolts or rivets 6 to impose a stress on the rubber sufficient for securing an intimate cementing or adhesion of the parts when subjected to heat treatment, the temperature being less than that at which the rubber will flow. Plastic rubber may be inserted between the parts and the vulcanization and curing of the rubber may be effected in position. The rubber may also be secured to the metal parts by cold cements. The holes 9 in the plates 2 through which the bolts 6 pass may be enlarged to allow relative movement between the plates 2 and 3, 4.
