Patent GB-782474-A (GB)
Title: Production of silica hydro-organosols and aerogels
IPC: C01B33/158
Filed: 1955-08-22
Abstract: Acidic silica hydro-organo sols containing colloidal silica, water, a water-miscible organic liquid, mineral acid in an amount to give a pH of 1.8 to 4.5 and a salt of the mineral acid is treated either successively or simultaneously with the hydrogen form of a water-insoluble strong cation-exchange material and with a volatile organic acid salt of a water-insoluble weak base anion-exchange material at a temperature not exceeding 15 DEG  C. to reduce the salt content.  A silica aerogel substantially free of electrolytes is produced by heating the above sol to convert it to a hydro-organoyl and heating the gel in a closed vessel without any compressive liquid-solid interface until all the liquid has been converted to a vapour which is allowed to escape, e.g. as in U.S.A.  Specification 2,093,454.  Specifications 649,896 and 654,850 also are referred to.

Title: Sound level comparator
IPC: G10K11/28
Filed: 1975-06-05
Abstract: 1498220 Measuring sound level TELEDIFFUSION DE FRANCE 5 June 1975 [5 June 1974] 24319/75 Heading G1G [Also in Divisions H3-5] A sound level comparator having two signal processing channels for signals from respective microphones, is characterized in that at least one of the microphones 61, has a cardioid directional response and has its diaphragm at the focus of the paraboloidal part of a part cylindrical/part paraboloidal housing 51. The housing provides acoustic screening and, as shown, has a flexible seal 52 for contacting a wall whose acoustic insulation properties at localized regions are to be measured. For this measurement both microphones are housed as shown, one being at a fixed location on the wall and the other being scanned over the wall surface. An optional second housing 51' enhances the screening of the microphone from extraneous noise. The directional characteristics of the microphone 61 plus housing enable the comparator to be used also for determining the individual contributions of several sound sources to the total received sound at the comparator, the other microphone being un-housed and omnidirectional. For this use, the signal channel with the housed microphone 61 includes a third-octave band-pass filter centred on 5kHz, the other channel includes a third-octave band-pass filter centred on 100 Hz, the comparator is initially calibrated by adjusting the relative gain of the two channels to balance the two channel signals responsive to a source of white noise or recorded traffic noise, and the required contributions are then measured by varying the orientation of the microphone housing 51 and noting sound level variations. The two signal channels each include, an AGC amplifier and a network which gives frequency-amplitude weighting according to the International A-weighting curve.
