Patent GB-2071370-A (GB)
Title: PCM Signal Processing
IPC: G11B20/18
Filed: 1981-01-23
Abstract: A method of preventing errors in a PCM error-correction decoder of the type supplied with successive transmission blocks, each comprising time-interleaved PCM, error- correction and error detection words, wherein the transmission blocks are selectively supplied from first and second data sources such that an error interval is produced as a function of the transition period during which the selection of the data sources is changed over from one to the other. According to this method, the presence of an error in a supplied transmission block is detected, and each of the time-interleaved words included in that transmission block is identified as being erroneous. The transmission block is time de- interleaved to recover a de-interleaved block comprising de-interleaved PCM and error-correction words. An erroneous PCM word in the de- interleaved block is corrected as a function of the remaining non- erroneous PCM and error-correction words in that de-interleaved block. However, the correction of a PCM word is inhibited if the block in which that word is disposed contains at least one word derived from the first data source and another word derived from the second data source.

Title: Resin/Ferrite Adsorbents and Their Production
IPC: C02F1/28
Filed: 1981-02-20
Abstract: An adsorbent is described which has been prepared by subjecting to curing a mixture comprising (a) one part by weight of (i) at least one hydrated ferrite of titanium, zirconium and tin or (ii) a mixture of such hydrated ferrite(s) and at least one hydrated oxide of titanium, zirconium, tin and iron with (b) from 1/10 to 3 parts by weight of a thermosetting resin having resistance to acids and alkalis such as an unsaturated polyester or polyurethane resin. The adsorbant can be used to adsorb a great variety of anions and cations and is especially useful as an adsorbent for phosphate ions. It has excellent resistance to acids and alkalis, and can be subjected to repeated desorption and regeneration procedures without causing any deterioration in its adsorptive capacity, thus permitting its repeated usage over a long period of time. It can be magnetically separated which facilitates its separation from liquids.
Patent GB-2074732-A (GB)
Title: Ultrasonic imaging system
IPC: A61B8/00
Filed: 1981-03-05
Abstract: An ultrasonic imaging system comprises a first array of transducer elements 10 adapted to be coupled to an object to be examined, which elements receive ultrasonic echo signals indicative of acoustic reflecting surfaces in the object. The received echo signals are converted by the first array of elements into electrical signals which are stored at 24 and retrieved so as to provide time reversal (time inversion) and thereafter used to energize a second array of transducer elements 27 coupled to a reconstruction medium 30. The ultrasonic signals transmitted by the second array, responsive to the time-reversed electrical signals, produce in the reconstruction medium a reconstructed acoustic image of the acoustic reflecting surfaces in the object. A visual image of the reconstructed acoustic image is obtained by acousto-optical means 32, such as a Schlieren device, and displayed at 36. <IMAGE>

Title: Electric hot plates
IPC: H01H37/34
Filed: 1981-07-24
Abstract: An electric hot plate has an overheating safety switch having a steatite housing which is inserted into the lower sheet cover plate of the hot plate and is supported with two feet on the lower side of the heating elements of the hot plate. A bimetallic member is positioned parallel between these feet which acts on a snap switch positioned in the steatite housing via a transmission rod.

Patent GB-2090283-A (GB)
Title: Coal hydration method
IPC: C10G1/08
Filed: 1981-06-11
Abstract: In a coal hydration method, wherein the hydrated product is fractionated in a hot separator (9) arranged downstream of the reaction area (8) into a head product (10) in a vapour phase and into a distillation residue (11) containing a liquid heavy oil, non distillable compounds and solid materials, a portion of the heavy oil separated coming from the distillation residue of the separator will be returned (16) into the separator. Thereby, the residue of the separator will be diluted. The tendency to coking will then be reduced; hence, the hot separator will be able to operate at higher temperatures As a result of these higher temperatures, the hot separator will produce more head products, and to this effect a bigger quantity of heat will be available for the heating of fresh coal through heat exchange between the head product and the fresh coal.

Title: Plaque for making brass rubbings
Inventor: CHAPMAN FRANCIS EDWARD LEIGH
IPC: G03F5/00
Filed: 1982-08-13
Abstract: A method of producing a plaque suitable for use in producing decorative rubbings which have a realistic photographic quality is described. The method involves preparing a screened image of a photograph or drawing, enlarging the resultant dot image and using this for the etching step of a sheet. Alternatively the photograph or drawing is scanned and the resultant optical signals used to control a cutter, the dots being of different sizes to give a shading effect when a "brass rubbing" is made.

Title: Compositions and methods to reduce animal browsing damage to plants
Inventor: ALLAN GEORGE GRAHAM
IPC: A01N59/02
Filed: 1982-11-03
Abstract: Damage to plants by browsing animals or insects is reduced by systemically inducing a nonphytotoxic dosage of selenium into the foliage of the plants at a level sufficient to repel animals and insects by means of a selenium compound having a selenium valency not exceeding 4<+>. The method is particularly suited for use in reforestation of pines, firs, and other conifers. The selenium may be systemically absorbed into the plants after application to the surrounding soil in the root zone of seedlings, preferably as a selenium compound, such as sodium or ammonium selenite or dimelamine selenite. Dimelamine selenite is a novel compound.
