Title: Improvements in or relating to filters
IPC: B01D25/00
Filed: 1963-06-25
Abstract: Metal fabrics are used, each composed of warps of one composition (e.g. stainless steel) and wefts of another composition (e.g. an alloy).  Two or more such fabrics are placed together, with the stainless steel filaments crossing at an angle (e.g. 90 degrees). Several such pairs of fabrics, each pair being separated from adjacent pairs by plates 29, Fig. 4 (not shown) of non-sintering material, are located between flanged metal walls 17, 21, at least one of which is flexible (with further intervening plates 29), and the walls are welded together to form a container.  An outer container is formed by two further flanged metal walls welded together.  First argon, then hydrogen, is passed through both containers, using pipes 25, 27, 38, 39 incorporated in the assembly; during the hydrogen circulation the assembly is heated to sintering temperature, 1900  DEG F.  When this temperature is attained, the inner container is evacuated and the intervening space is continuously supplied with hydrogen at low pressure.  The inner container collapses upon, and compresses, the fabrics in each pair, so that sintering takes place.  Thereafter the assembly is air-cooled and water-quenched, and the containers are sawn open to release the now-composite fabrics.  Finally, the alloy filaments are dissolved out in hot nitric acid.

Filed: 1960-07-26
Abstract: 960,589. Cine cameras. K. SCHAEFER. July 26, 1960 [July 30, 1959], No. 25971/60. Heading G2E. The motor of a cine camera is switched on and off by application of manual pressure on a spring membrane anchored in a light-proof manner in the housing and by release of such manual pressure respectively. As shown in Figs. 1 and 3, a stressed annularly corrugated over-centre spring membrane 35, set in the camera wall 1 and electrically connected to the motor 4 through battery 40, can be pushed by finger pressure in direction 43 to spring post the mean surface of greatest stress first of all closing a circuit including a spring blade 30 (see Fig. 2) to start motor 4 running and then to deflect the spring blade 30 to disengage a stop 37 on a rotatable shutter disc 8 to free the camera drive system. The drive is derived from pinion 5 of motor 4 via spring belt 6 to rotate shutter disc 8, the shaft 9 of which transmits rotation via spring belt 12 to the take-up spool 15. A claw lever 19 having a claw 23 is pivoted at 20 and is oscillated by rotation of the eccentric hub 18 with which it is held in contact by spring 22. To stop the camera, finger pressure on the membrane 35 is released, the strain in the stressed spring blade 30 being sufficiently large to carry the membrane 35 back through the surface of greatest stress. Prior to the completion of this action of blade spring 30, the shutter disc 8 will have rotated to bring a rising wedge-shaped cam projection 28 past the tip 33 of the spring blade 30 which finally falls between the cam projection 28 and the stop 27 to lock the shutter disc 28.

Title: Process for improving the properties of wool and other animal hairs
IPC: D06M15/41
Filed: 1947-09-25
Abstract: Wool and other animal hairs, and intermediate and finished textile fabrics manufactured from them, are impregnated with an aqueous solution of a precondensation product of formaldehyde and resorcin or a substituted resorcin, the pH of the solution being from about 2.8-5.  Filter cloth, woollen filter bags, woollen carpets, felt, and other animal hairs such as horse-hair may be treated.  At least 6 gram-molecules of formaldehyde per grammolecule of the resorcin may be used, and the final condensation on the material may take place at a temperature of 100-140 DEG  C. and preferably 100-110 DEG  C.  The pH of the solution before application to the material may be corrected if necessary by the addition of weak acids or alkalies, for example lactic acid.  In one example, a mixture of formalin and resorcin is heated for 30 minutes to 60 DEG  C., cooled and water added.  Wool fibres are placed in a bath of this solution and after 30 minutes the wool is centrifuged, dried at 70 DEG  C., and finally heated for 30 minutes at 105 DEG  C.  1.3-Dihydroxy-6-chlorobenzene may be used instead of resorcin.  By this treatment the material is softened and made more resistant to acids and alkalis, its tensile is strength improved, and shrinkage is decreased.  Specification 649,974 is referred to.
