Title: Filtering medium for liq.
Inventor: TAKASHIMA MASARU
IPC: B01D/
Filed: 1981-01-08
Granted: 1987-05-20
Abstract: Filtering medium for liqs. comprises a sintered body contg. 100 pts.wt. of a refractory prod. based on alumina of which more than 95wt.% is pelleted spheroids of particle size less than 1.0 mm; and 15-30 pts.wt. of an inorganic binder of particle size below 40 microns; and 0.1-1 pt.wt. LiF and/or Li2O, the mean dia. of the pores of the filtering medium being of the order of 500-1 microns and its porosity is 15-40%. The spheroids are less liable to break or wear during filtering when in loose fill filtering bed. More consistent porosity of the filter bed is achieved. Particles broken from the filter particles are less liable to be carried through the filter bed with the filtrate. The particles provide greater filling capacity per unit weight than in prior art.

Abstract: The invention refers to the structural elements used in the civilian construction, in particular to the structural element shaped as six-sided polyhedron (fig. 1), for example, shaped like cube or dice, rectangular prism or prism in general, made of light material latticework of frameworks, which are able for elastic deformations in defined plane under the applied load at the same time being able to assure quite big strength and stability to the structural element under normal service conditions. The mentioned frames include four non-bearing walls/sides of certain thickness and design, which can be done, or as one-piece pneumatic structure, or like four sides flat wall structure, surrounding the bearing frame. At that the four sides of the structural element along their edges are united by joints or ropes, but the two side planes, which in the operating conditions perform also side bearing functions can be movable, openable, detachable or in other words space convertible and/or changeable, by rotation of separate elements one relative to another around one or other axis. The proposed dice shaped structural element can be used as like separate habitation, as well as a module for building of complicated architectonic form of convertible dwelling complex building, where a small room can perform different functions.

Title: Method for production of microcrystalline cellulose
Inventor: LAKA MARIANNA
IPC: C08B1/00
Filed: 1994-10-13
Abstract: Invention refers to the production of cellulose materials and can be used in the chemical industry for the production of composites and sorbents containing cellulose, and in the pharmaceutical industry for the production of pills, unguents and powders.The task of the invention is to increase the chemical pureness of microcrystalline cellulose and homogeneity of its granulometric composition, as well as decreasing costs of the process. The task is solved by using 0.04-0.10 % HCl solution in the water in the well known method - impregnation of cellulose with catalyst solution, pressing, thermal treatment up to a dry condition and reducing it to small pieces - but the thermal treatment is done at temperatures of 110-130 degrees C. In case it is needed to reach a higher degree of whiteness, the microcrystalline cellulose is bleached after reducing it to small pieces .

Filed: 1991-05-07
Abstract: Framgangsmåte for utvinning av geotermisk energi og mineralresursser i den såkalte svakhetssonen i jordskorpa, hvor det utvikles en varmesone i et område av den kontinentale litosfære hvor skjærstyrken av det varme fjellet plutselig faller med økende overdekning og hvor vannbrytningen som er nødvendig for å skape varmeoverflater bevirkes under det hydrostatiske trykket av ei vannsøyle i et fdret borehull med tilsvarende dybde. Vannet påsettes på enkel måte et ekstra utvendig trykk for å skape de initielle sprekkene i den nedre ufdrete delen av borehulet. Denne framgangsmåten overvinner de tekniske begrensninger som har vært beheftet med den såkalte Hot-Dry-Rock-prosessen som ikke har vært i stand til å overvinne skjærstyrken i fjellet under en viss dybde for dannelse av varmeoverflater ved vannbrytning.

As shown, a driving shaft 3 in an embroidery machine pivotally carries a plurality of pairs of members 5 rotatably supporting shuttles S the bodies S' of which have peripheral gear teeth 4 meshing with a gear 2 rigid with shaft 3. A circumferential groove S in body S' is engaged by a pair of pins 7 journalled on member 5, and a circumferential rib 9 on gear 2. Members 5 may be pivoted outwards from their operative positions to provide access to the bobbin carriers S" mounted therein. The shuttles co-operate with respective horizontal needles N mounted on a reciprocating bar 21. The work M passes between a vertical surface and a spring-biassed presser plate 20. Needle thread passes from a tensioner 31 to guides 32 and 33 positioned one on each side of a rotary shaft 24 the thread returning -from guide 33 to guide 32 on its way to the needle. The doubled thread between said guides is acted upon by a rotary take-up member 25 generally L-shaped in cross section and rigid with shaft 24. Work M is fed longitudinally, while shaft 3, needle bar 21 and shaft 24 are shifted laterally as a unit in accordance with the pattern requirements. In a modification, each shuttle of a pair is driven from a separate shaft pivotally supporting the associated member 5.
