Title: Process for dehydration
IPC: A23B7/02
Filed: 1965-12-08
Abstract: Edible animal and vegetable materials are dehydrated by forming a stable dispersion of the material in finely divided form and a hydrophobic, edible fluid substance, and drying the dispersion at an elevated temperature under vacuum on a wiped film type of evaporator. Specified materials include fruits, vegetables, gelatin, fish and seafood products, meat and meat by-products, fruit and vegetable pulps, onions, garlic, horseradish, fruit juices, vitamin extracts and medicinal plant materials.  The hydrophobic substance may be an edible vegetable oil or a partially esterified glyceride or, where a non-edible substance is suitable, may be cetyl alcohol, microcrystalline wax, spermaceti or low melting point hydrocarbons. Some materials are advantageously treated with hydrolysing enzymes before, during or after grinding to reduce the water holding capacity of hydrocolloids they contain.  Free juice may be mechanically removed, e.g. by centrifuging, from the dispersion before the drying operation.  Excess oil may be filtered off from the dehydrated product and reused in the process.  In the examples avocado pulp, skinned and seed-freed tomatoes, and cooked chicken meat are dehydrated after dispersing in sesame or coconut oil. Avocado paste is made from the thus dehydrated avocado pulp by incorporating therein sodium chloride, pectin, dried skim milk, and either methyl cellulose, methyl cellulose and dextro maltose, or sodium alginate.

Abstract: 1331850 Gear pumps FIAT SpA 10 Nov 1971 [17 Nov 1970] 52265/71 Heading F1F [Also in Division G3 ] In an hydraulic gear-pump comprising two pairs of gears A 1 , A 2  operating in parallel and having common inlet and outlet conduits 4, 5, co-axial main and pilot spool-type valve-members 21, 42 operate so as to bye-pass the gears A, when the outlet pressure rises to a predetermined value. The valve members are lodged in a fixed casing-part 10 and loaded by compression springs 41, 52. At low pressures the valve members occupy the positions shown in Fig. 2 and the gears A 1  deliver fluid to the conduit 5 by way of conduits 8, 9 and annular chambers 18, 19. When the said value is reached pressure transmitted through openings 29 to an annular chamber 28 lifts the pilot valve-member 42. A chamber 20 is thus connected to the chamber 28 by way of openings 31, 57 and consequently the main valve-member 21 is raised to the position shown in Fig.3. The conduit 8 is thereby shut off from the conduit 9 and connected to a conduit 7 on the inlet side of the gears A 1  through a further annular chamber 17. While the main valve-member is in transit, pressure in the conduit 8 is relieved by a ball valve 61 in a path inter-connecting the chambers 18, 19, Fig. 5. When the valve members are in the Fig. 2 position the pressure in the chamber 20 is equalized with that in the conduit 7 by openings 34, 44, 45, which relieve fluid trapped in said chamber when the valve members descend.
