Title: Production of fibre mats
Inventor: HARTMANN LUDWIG
IPC: D04H3/03
Filed: 1963-11-18
Abstract: 1,067,847. Forming fibrous mats. CARL FREUDENBERG CO. Nov. 18, 1963, No. 45442/63. Headings D1F, D1N and D1R. A uniform, non- woven fibrous mat having no capacity for delamination comprises continuous individual filaments (as may be produced in the manner described in Specification 1,053,222) randomly arranged in all directions throughout the entire thickness of the mat and individually entangled with one another. As shown in Fig. 1, freshly spun filaments in the form of a sheet passing through a duct (not shown) are stretched and carried forward (by streams of air emerging from slots 3 in a spinneret 1) to the nip between hollow perforated rollers 4 which, with rollers 5. form supports for endless perforated belts 6. The surface speed of the belts is much less than the speed at which the filaments are delivered to the nip, so that the filaments accumulate into a mat 7 between adjacent runs of the belts as they are advanced thereby. The air streams from slots 3 become turbulent before reaching the nip and thus oscillate the filaments which, as they approach the nip, are subjected to transverse air currents established by air entering suction chambers 8. The filaments are therefore seized irregularly by the turbulent air streams and interentangled. The process is stated to be applicable to the production of mats of staple fibres by blowing such fibres to the nip.

Filed: 1964-11-11
Abstract: 1,040,128. Sewing. SPINNEREI UND WEBEREIEN ZELL-SCHONAU A.G. Nov. 11, 1964 [Nov. 11, 1963], No. 45924/64. Heading D1G. [Also in Division B8]  Apparatus for separating faulty articles from perfect articles comprises a storage unit stepped in synchronism with the movement of said articles through the various working positions of a production line, means for imparting separate storable information to said unit, the latter having members settable in at least two states according to the information received, and said means being operable in response to a signal from one or more working positions, and means for sensing the state of said members and operating a sorting system to separate faulty from perfect articles at the end of the production line. As shown, a rotary disc 1 slidably carries a plurality of radial pins 2, each of which can correspond to a working station or machine, and which is normally in an outwardly-displaced position. On transfer of a workpiece from one station or machine to the next, disc 1 is stepped by an amount equal to the angular distance between adjacent pins 2, by means of a solenoid 5 acting on disc 1 via a linkage 6, a pawl 7 and a ratchet wheel 8. At the stationary position of each pin 2 is a solenoid 3 which is energized if a defect is detected at the corresponding station or machine, whereby the plunger 4 of said solenoid pushes the adjacent pin inwards. At the final step of disc 1, the inwardly displaced pin 2 allows light from a lamp 9 to be reflected from a mirror 13 on to a photo-cell 10. During the next step said pin is pushed outwards by a fixed cam 12. The impulse generated in the photo-cell serves to reverse the direction of a motor driving an endless conveyer band, the arrangement being such that a completed workpiece deposited on the band is conveyed in one direction to one stack if perfect, and if defectice is conveyed in the other direction to a second stack.

Title: Process for recovering acrylic and methacrylic ester
IPC: C07C51/48
Filed: 1965-11-05
Abstract: Acrylic and/methacrylic acids are recovered as esters from an aqueous solution of the acids by extracting the solution with an organic solvent which is substantially immiscible with water, separating the organic phase from the aqueous phase, esterifying the acids in the organic phase with an alcohol in the presence of an ion-exchange resin which is insoluble in the organic solvent, and recovering the resulting esters from the organic phase. Specified extracting solvents are tri-n-butyl phosphate and acetophenone.  It is preferred to effect esterification at a temperature corresponding to the boiling point of the alcohol and in the presence of a cation exchange resin.  The process is illustrated by reference to a flow diagram (not shown).  Examples relate to the methyl esters.
