Title: An improved apparatus for pressing out oil-containing seeds or fruit
IPC: B30B9/04
Filed: 1928-10-27
Abstract: 303,498. Duchscher et Cie. Jan. 6, 1928, [Convention date]. Platen presses.-In an hydraulic press for extracting oil from seeds or fruit, rotatable devices are mounted on supporting columns e, e<1>, the lower one consisting of press boxes g, g<1> and the upper one of a thrust block h and discharge box h'. In operation the thrust block h, Fig. 1, and one of the press boxes g<1> filled with seeds or fruit separated by filter plates, are brought into position above the plunger b. After pressure has been applied the upper device is rotated to bring the discharge box into position above the box g', the contents of which are lifted by the plunger into the box and are retained therein by a detent mechanism i, i<1>, Fig. 4. The upper member is rotated to return the thrust block h and bring the box h<1> into position for the discharge of its contents, and the lower member is rotated to bring the press box g filled with seeds &c. above the plunger. The rotating devices may be held in position by locking members m, Fig. 7, engaging notched lugs n on them.

Patent GB-700184-A (GB)
Title: Improvements in or relating to the production of nitriles
Filed: 1950-12-22
Abstract: Organic nitriles are prepared by heating an alcohol or an aldehyde with ammonia in the presence of a zinc sulphide catalyst. Starting materials mentioned include monohydric alcohols and the corresponding aldehydes which may be acyclic or cyclic, including aromatic, alcohols and aldehydes, glycols and dialdehydes.  A suitable catalyst is prepared by distributing zinc sulphide on pumice and drying in nitrogen.  Commercial zinc sulphide containing zinc carbonate and sulphate or the product obtained by passing hydrogen sulphide into zinc acetate solution gives good results whereas a product obtained by treating zinc carbonate with hydrogen sulphide is less active. Catalysts prepared in the presence of excess water appear more active.  Preferably the reactants are preheated separately and brought together in the p  reaction zone.  In examples: Heptonitrile is obtained from n-heptyl alcohol (I) and oenanthal (IV) respectively by reacting with ammonia using a catalyst comprising zinc sulphide on pumice; trimethyl capronitrile and a mixture of nitriles boiling in the range 76-79 DEG C. at 19mm. Hg are similarly obtained from 3:5:5-trimethylhexan-1-ol and a mixture of "Oxo" alcohols having from 7 to 9 carbon atoms respectively by reaction with ammonia (II and III) and trimethylcapronitrile is obtained in a similar process using a catalyst comprising zinc sulphide precipitated with hydrogen sulphide from zinc acetate solution (V).  In example (I) gaseous olefines and paraffins are stated to be produced as by-products.
Patent GB-179208-A (GB)
Title: Improvements relating to the manufacture of plastic materials or articles having a basis of cellulose acetate
IPC: C08L1/12
Filed: 1920-11-04
Abstract: Cellulose acetate, preferably dry, is mixed in the absence of volatile solvents with not more than 50 per cent of its weight of a plastifying or softeningagent not saponifiable with water, with or without dyes, filling substances &c., and heating during the mixing &c. to a temperature of 100-150 DEG  C. or higher to melt the acetate in the plastifying agent.  The mass, with or without subsequent working on rollers may be moulded under heat and pressure, cast, run into sheets or films, extruded through dies &c.  According to an example, 100 parts of ground air-dried cellulose acetate are kneaded with 30-40 parts of isomeric xylene-o-monomethyl sulphonamides as described in Specification 132,283, with or without 6-8 parts of triphenol- or tricresylphosphate the mass being heated during the kneading to 100-150 DEG  C. or higher, a vacuum being applied if desired.  Dyes and filling materials may be added and the mass may be worked between rollers heated to a higher temperature than usual, for example, 90-100 DEG  C., and moulded, pressed, cast, extruded, &c. The Provisional Specification also states that volatile non-solvents such as benzol may be employed to facilitate mixing.
Patent GB-842225-A (GB)
Title: Improvements in cold joining of polyester resins
IPC: C08J5/12
Filed: 1957-10-07
Abstract: Partially cured or uncured unsaturated polyester/monomer compositions are bonded to partially cured similar compositions or partially cured organopolysiloxane gums by contacting the two materials and irradiating with high energy radiation.  The polyester may be in the form of sheets or liquid coatings on the other polymer.  In examples styrene - unsaturated polyester resins were partially cured in thin films by irradiation with high energy radiation.  The films were removed from the base, placed in intimate contact and subjected to high energy radiation to weld the films together.  In other examples a liquid polyester-styrene composition was painted on a partially cured polyester-styrene resin and irradiated to cure the coating and bond it to the base. In further examples sections of polysiloxane gum were bonded to a partially cured or to liquid uncured polyester-styrene resins by high energy irradiation.  The degree of cure may vary throughout the thickness of a polymer layer.  The invention may be applied to electrical insulation by wrapping a partially cured polyester-styrene tape or a composite polysiloxane gum/polyester-styrene resin tape around a conductor and irradiating the wrapped insulation to bond the parts together. The resins may be filled with conventional fillers or combined with glass, asbestos or other fibres.  The Specification gives combinations of plastic materials which do not bond together under the influence of high energy radiation.

Abstract: 1482492 Winding webs HOESCH WERKE AG 28 July 1975 [2 Aug 1974] 31508/75 Heading B8R Apparatus for winding longitudinally slit metal webs into rolls comprises two expansible web roll spindles 10, 11 carried by respective driven shafts 8, 9 mounted in a housing 2. The latter has a circular peripheral portion rotatably supported on a frame 1. Rotation of the housing by a motor 3 interchanges the positions of the spindles so that the completed rolls wound on spindle 10 in its illustrated position can be off-loaded onto a truck 24 when the spindle 10 is moved to the illustrated position of spindle 11, whilst further winding can proceed on spindle 11 in its new position. A winding motor 19 and reduction, e.g. planetary, gearing 16 are fixed either to the housing 2 or to the frame 1, and drive therefrom is transmitted via a gear-wheel 15 on a central shaft 14 to gear-wheels 13 freely rotatably mounted on the driven shafts 8, 9. Electromagnetic or hydraulic clutches 20 couple the driven shaft and associated spindle in the winding position to the corresponding gearwheel, and couple the shaft and spindle in the off-loading position to the housing 2 thereby braking that spindle. Trailing web ends are held against their rolls by pivotable arms (22), Fig. 3 (not shown).
