IPC: G01M3/38
Filed: 1998-03-25
Abstract: "SISTEMA FOTO-ACúSTICO PARA DETECçãO DE VAZAMENTOS E PROCESSO PARA DETECçãO DE UM GáS QUE VAZA DE UM COMPONENTE". Trata-se de um sistema foto-acústico para detecção de vazamentos para detectar um gás que vaza de um componente (30), que inclui pelo menos um feixe de laser (20), que incide sobre o componente (30) e que possui um comprimento de onda que é absorvido pelo gás, o gás emitindo um sinal foto-acústico (36) quando o gás absorve luz do feixe (20), o feixe (20) sendo pulsado numa freq³ência de pulso, a freq³ência de pulso sendo relacionada com uma freq³ência de detecção do sinal foto-acústico e sendo uma freq³ência na qual a magnitude de ruído acústico de segundo plano na freq³ência de detecção se encontra num nível baixo previamente determinado, pelo menos um sensor acústico (40), que recebe o sinal foto-acústico (36) e fornece um sinal de sensor através da linha (42) indicativo do mesmo para um filtro (44) e um detetor síncrono (18), que fornecem um sinal filtrado através de uma linha (50) para um processador de sinais (52). O processador (52) fornece um sinal de saída através de uma linha (54) indicativo do vazamento no componente. O ajuste dessa freq³ência de pulso para uma freq³ência de ruído acústico de nível baixo permite um aumento significativo da resposta de sinal-para-ruído.

Abstract: In mouldings designed to have resistance to mechanic shock as well as chemical resistance to oil and petrol, as in pipes and rainwater goods, combinations of rubber or other elastomers and thermoplastic resins are used but may show poor ageing resistance to light etc. It has now been found that good ageing resistance, with above properties is obtained by using partially satd. elastomers produced by copolymerisation of butadiene with alkyl acrylates. Compositions are produced by mixing a thermoplastic resin (A) with a tetrapolymer (B) (elastomer) where (A) is a copolymer of styrene-acrylonitrile (or analogue) or other monomers of vinyl series, and (B) is the product of polymerisation of a monomer mixt. of styrene and acrylonitrile.

Title: Impregnating cellular support materials with bitumen - or similar solutions
Inventor: PHILOMENA JOZEF DE NEEF PAUL J
IPC: C08J9/42
Filed: 1968-09-19
Abstract: Cellular elements are impregnated with a bitumen solution. The cellular support is immersed in the solution for a sufficient time to obtain the required degree of impregnation and the impregnated support is then subjected to energetic rotation for a period and at a speed determined relative to the product required. The rotation may be about a horizontal, vertical, or inclined axis, which may itself be in motion. The motion imparted to the impregnated element may be cycloidal. Excess solution displaced by centrifugal force is regenerated by the liquid impregnation medium of the first phase of the process. The addition of medium to the excess solution is controlled so that the conditions of the medium are maintained constant. Process, which is applicable to any kind of deformable cellulose support, has improved efficiency without risk of damage to the product.
