Title: Method of crimping textile fibres
IPC: D02G1/12
Filed: 1950-09-28
Abstract: <PICT:0691391/IV (c)/1> An artificial crimp is imparted to textile fibres by passing them through a zone containing a heated fluid and moisture, maintaining them in this zone for a time to presoften them for crimping, gripping them between closely-spaced conveyer surfaces discharging into a substantially closed zone and forcing the gripped fibres into the latter zone against the pressure of a mass of fibres held compacted under pressure therein, the said pressure being adapted to cause the fibres to be progressively folded over and crimped as they are delivered from the conveyer surfaces, holding the mass of crimped fibres compacted under a substantially constant pressure to retain the crimp therein, introducing a setting agent under pressure into the closed zone, treating the mass while thus compacted with the setting agent under conditions to produce a permanent set of the crimp in the fibres, and withdrawing the fibres from the said closed zone.  As shown, opened and scoured wool is fed in sliver form 74 through a pre-treating tank 70 containing water or a chemical setting agent such as thioglycolic acid heated (e.g. to 212 DEG  F.) by a steam pipe 73.  The treatment time is such that the fibres swell and soften by absorbing within themselves 20 to 30 per cent of their weight of moisture.  Instead of using liquid treatment, the fibres may be subjected to steam, preferably saturated, to give the same swelling and softening effect.  The pre-treated fibres are then passed by rollers 11, 12 through crimping and setting chambers 36, 34 as described in Specification 690,063, in which they are treated with a setting agent such as superheated water, steam or a chemical supplied through a pipe 65.  As chemical setting agents, thioglycolic acid and its salts, formaldehyde, or a sulphoxylate formaldehyde may be used.  The setting agent may be heated to a temperature between 212 DEG  and 275 DEG  F.  Any excess of water or other setting agent drains out of the bottom of the setting chamber 34. The emerging sliver, which is characterized by sharp angular crimps, may be dried, carded and spun in the usual manner. Specification 682,263 also is referred to.
Patent GB-688864-A (GB)
Title: Method for the production of lead
IPC: C22B13/00
Filed: 1950-09-28
Abstract: A method of producing lead from sulphide ores such as galena or sulphidic lead concentrates is characterized by the use of waste aluminium or waste aluminium alloys as the reducing agent.  These waste metals are those which, in consequence of surface contamination, are incapable of use for their original purpose or for other purposes.  The reaction may be carried out in hearth furnaces or short drum furnaces, lined with bricks or tamped masses of dolomite or magnesite, and preferably in the absence of air or in an inert gas atmosphere.  Flue dust arising from the process may be recycled or subjected to separate treatment.  The reduction preferably takes place at temperatures at which negligable evaporation of lead takes place and at which the aluminium sulphide slag can be easily separated from the metallic lead produced.  The lead may be continuously drawn off and the slag continuously or intermittently.  In the latter case the temperature may be raised to about 1200 DEG C-1300 DEG C for a short time by charging relatively large quantities of reactants to ensure tapping a fluid slag. Specifications 10303/06, [Class 82], and 669,272 are referred to.

Abstract: 1,117,544. Treating polyethyleneterephthalate film; laminates. UNIROYAL Inc. 31 May 1966 [27 Sept., 1965], No. 24181/66. Headings B5B and B5N. A polyethyleneterephthalate sheet or film is infused with an acetic acid substituted with an electrophilic group and is thus capable of adhering to a diolefin rubber stock containing a methylene donor and a methylene acceptor reactive to form a resorcinol/formaldehyde type resin upon vulcanization of the stock. The film is prepared by immersing it in a solution of the acid (aqueous or in an inert organic solvent) at a temp. not less than 30 C. below the glass transistion temperature of the polyester (about 80 C.). Suitable acids are mono-, di- and trihalogen substituted acetic acids; other electrophilic substituents are phenyl or phenoxy. Exemplified methylene acceptor/donor combinations are resorcinol/1,3,5-tris(cyanomethyl)- hexahydro - s - triazine, and resorcinol - acetone condensation product/5-methylol-1-aza-3,7-dioxabicyclo-[3.3.0]-octane; many others are mentioned. The rubber may be natural, a homopolymer of a 1,3-conjugated diene, or a copolymer thereof with up to 50% of a copolymerizable monoethylenically unsaturated monomer. Laminates are prepared from films of polyethyleneterephthalate and the diolefin rubber stock, both as above, by incorporating a sulphur type vulcanizing agent in the rubber, placing the impregnated polyester in contact therewith and heating until the rubber becomes vulcanized.

Title: Weighing apparatus for continuous weighing of equal amounts of granular material
Inventor: RAMBOLD ADOLF
IPC: G01G19/22
Filed: 1955-08-23
Abstract: 785,494. Photo-electric control of weighing apparatus. TEEPACK SPEZIALMASCHINEN GES. Aug. 23, 1955, No. 24228/55. Class 40 (3). [Also in Group XVIII] In apparatus for continuously weighing equal amounts of granular material and of the kind in which a weigh beam carries a load pan on each side and is loaded alternately on each side with a weight corresponding to the desired amounts of granular material, there is a stationary weight support on each side so that equal value weights on both sides can be raised from or lowered on to the support in a substantially vertical direction during part of the rocking movement of the weigh beam and a detector (which may include a photo-cell) for controlling the switching of the flow of granular material from one load pan to the other on reaching the required weight. As shown, the weigh beam 1 is pivoted at 3 on a stand 2 and pivotally carries load pans 4<SP>1</SP>, 4<SP>11</SP> which are to be alternately filled with equal amounts of material fed from a hopper 23 through vibrating feeding channels 25 controlled by electromagnets 34. The pans 4<SP>1</SP>, 4<SP>11</SP> are accommodated in openings 12 in a stationary plate 11 which carries supports 14<SP>1</SP>, 14<SP>11</SP> which are adjustable in height. Conical openings in these supports accommodate weights 13 having conical recesses in their undersides for engagement, when the apparatus is in use, by conical pins carried by the pans 4<SP>1</SP>, 4<SP>11</SP>. A hinged lid 7 for each pan is normally kept closed by a counterweight 28 on a lever 29 and by a spring-tensioned locking lever 36 which engages a lever 30 secured to the hinge rod; an electromagnet 39 is provided to release each lever 36 and thus cause the related pan to open when the required amount of material has been fed thereinto. Also attached to the weigh beam is a forked lever 41 adapted to screen a photo-cell 42 on the hopper from a stationary light source (not shown) when one or other of the pans has been filled with the required amount of material. In operation, one pan, say 4<SP>1</SP>, is fed with material and the weigh beam rocks until the conical pins on the other pan have raised the weights 13 from their support 14<SP>1</SP>, 14<SP>11</SP>. When this occurs the forked lever 41 has moved to obstruct the light beam and this causes de-energization of magnet 34 so as to stop the feeding of material into pan 4<SP>1</SP>, energization of magnet 35 to release lever 36 and thus empty pan 4<SP>1</SP> and energization of the other magnet 34 to start feeding into pan 4<SP>11</SP>. The weigh beam then rocks in the other direction, the light beam again reaches the photo-cell and, when pan 4<SP>11</SP> has been filled, operations are repeated.
