Title: Noise-cancelling ear-worn speaker-carrying devices with vents to bypass seals and cancel sound leakage
Inventor: SIBBALD ALASTAIR
IPC: H04R1/10
Filed: 2007-02-16
Abstract: An ear-worn speaker carrying device ("ESD") such as a headset or earphones incorporates feedforward active ambient noise reduction circuitry. A seal 36 contacts or surrounds the ear of a user and is intended to present a substantial impedance to inward or outward transmission of sound to or from the ear. At least one acoustic channel of predetermined dimensions bypasses the seal to providing an acoustic leakage path of known characteristics, thereby permitting predetermined levels of sound to enter and exit by way of the channel, such that minor variations in leakage, dependent, for example, upon precise mounting of the seal to the ear as used from time to time, are rendered relatively unimportant. The device further comprises an acoustic conduit connected to vent the speaker's rear surface to the external ambient, and respective exit apertures for the acoustic channel and the acoustic conduit are so relatively located that sounds exiting from them tend to cancel each other, reducing sound emissions from the device. Each of the channel and the conduit may be damped (fig.5).

Title: Radar apparatus adapted to environments prone to strong multipath signal propagation
Inventor: HAYWARD STEPHEN DAVID
IPC: G01S7/41
Filed: 2008-10-13
Abstract: A radar system is disclosed for locating objects in a region 1 having a high degree of multipath susceptibility. The radar system comprises a plurality of transducers, each being a transmit antenna 5a-d or receive antenna 8a-d, and being arranged about the region 1 in known locations, to form a bi-static or multi-static radar 10. Signals transmitted by the transmit antenna(s) 5a-d are received at each receive antenna 8a-d and processed to form a set of channel impulse responses or power delay profiles representative of the region at a given time. A second set of channel impulse responses or power delay profiles are formed at a different time. The difference between the two sets contain information on movement within the region 1. The difference may be processed to locate the moving object(s) by generating an x-y image representative of the region, and accumulating at each pixel, appropriate values of the profile difference, selected according to the propagation delay between a transmit-receive antenna pair via a region point represented by the pixel.

Title: Process for the production of water soluble acids having a dissociation constant of less than 10 from their sparingly soluble salts
IPC: B01J47/10
Filed: 1957-03-28
Abstract: Water-soluble inorganic acids having a dissociation constant of less than 1 X 10-2.5 are prepared from their sparingly soluble salts by treating an aqueous dispersion of such a salt with an acid-cation exchange resin, the acid groups of which have a dissociation constant greater than that of the acid to be prepared, the individual granules of the ion-exchanger being moved relatively to one another and to the dispersion and running off the acid solution so obtained.  The treatment may be effected in a slowly rotating drum filter or in a column of large diameter having an air delivery device working on the air-lift pump principle and fitted into the centre of the column. The salt concentration in the dispersion may amount up to 400 gms/litre. After the conversion of the salt to the free acid and removal of the resulting acid solution, the ion-exchanger may be washed, providing a wash liquor utilizable in forming more salt suspension.  A suitable ion-exchanger is a cross-linked polystyrene having nuclear sulphonic acid groups.  The invention also includes the preparation in the same manner, of organic water-soluble acids having a dissociation constant below 1 X 10-2.5 and examples of this preparation are given (see Group IV (b)).ALSO:Water-soluble organic acids having a dissociation constant of less than 1 X 10-2.5 are prepared from their sparingly soluble salts by treating an aqueous dispersion of such a salt with an acid cation-exchange resin, the acid groups of which have a dissociation-constant greater than that of the acid to be produced, the individual granules of the ion-exchanger being moved relatively to one another and to the dispersion and running off the acid solution so obtained.  Suitably the exchanger granules are submitted to a whirling action which may be effected by using, as a reaction chamber, either a column of large diameter having an air delivery device working on the air-lift pump principle fitted into the centre of the column or a slowly rotating drum filter. The salt concentration in the dispersion to be treated may amount up to 400 gms/litre.  After the conversion the acid solution is run off and the exchanger is then washed and the washing liquid may be used in preparing aqueous salt dispersions for subsequent batches.  Finally the exchanger is regenerated preferably by means of hydrochloric acid.  Examples describe the isolation of tartaric and citric acids from aqueous dispersions of crude tartar and calcium citrate respectively using a cross-linked polystyrene ion-exchanger having nuclear sulphonic acid groups.  The recovery of lactic acid is also mentioned.
