Patent GB-2203574-A (GB)
Title: Parallel processor arrays
Inventor: JESSHOPE CHRISTOPHER ROGER
IPC: G06F15/80
Filed: 1987-04-03
Abstract: In a parallel processor array (Fig. 1) the array of processing elements (PE) is provided with an array of communications processors (CP) which handle all internode communications and preferably themselves form an SIMD machine. Each communications processor has bidirectional bit-serial connections to its four nearest neighbours and comprises four shift registers S1 to S4 which enable it to receive message bytes from all four inputs at once. A parallel bus 34 connects the registers to a buffer (32, 38 Fig. 2) which can be accessed by the associated processing element to write source data and read destination data. In a packet switching mode a message commences with address bytes which are compared with the communications processors own address. A message can be passed from node to node (Fig.4) to its destination address. A received message enters the buffer and address comparisons are effected to determine, by means of multiplexers 64, in which output direction the message will be transmitted from the buffer to the next node. The shift registers are preferably duplicated and connected to the input and output multiplexers by switching means 60, 62 controlled by a "page" bit 42 which determines which set of registers is available for input/output. The other set can be loaded and tested using the parallel bus, during transmission via the first set. In this way, the physical connections between communications processors may be used continuously. <IMAGE>

Title: Masked direction finder
Inventor: HARASIM ANTON
IPC: G01S3/781
Filed: 1987-05-12
Abstract: Optical system (1) images radiation, the direction of which is to be determined, onto an opto-electronic detector (4). A liquid crystal device (2) is placed in the path of radiation between the optical system (1) and the detector (4) for the purpose of masking-out sources of interference or other noise. The liquid crystal mask (2) has horizontal and vertical elements which are controllable by means of electronic row and column drivers (16). The opto- electronic detector (4) is a non- subdivided position detector which is associated with a direction determining system (5), the output signals of which control the row and column drivers (16). To isolate a source of radiation, the raster elements in a region around the position of a detected source of radiation are switched so as to be non- transmissive to radiation. <IMAGE>

Title: Speech recognition
Inventor: CAMERON IAN ROSS
IPC: G10L15/00
Filed: 1987-07-14
Abstract: Words uttered by a user are compared 2, with stored words 3; the word giving, the best "score" in the comparison is deemed to have been recognised. Where equal or similar scores occur the result is ambiguous and in that case a message is generated (eg by means of a speech synthesiser 7) containing a word for the user to confirm. If he does not, a second word may similarly be offered. <IMAGE>

Title: Expression vector comprising introns and transformed cells
Inventor: GORMAN CORNELIA MAXINE
IPC: C12N5/00
Filed: 1987-09-11
Abstract: Production of a desired heterologous protein comprises constructing an expression vector having a stabilizing sequence downstream of a promoter and upstream of the DNA encoding the desired heterologous protein, transfecting and choosing a particular eukaryotic host cell for said production and culturing the transformed eukaryotic host cell under favorable conditions. The stabilising sequence is an intron of a donor-acceptor-splice sequence, preferably from the immediate early gene of human cytomegalovirus or an immuloglobulin variable region. Vectors can be used for continuous production of factor VIII, t.PA and prorelaxin.

Patent GB-2208819-A (GB)
Title: Preparation of metallic interface
Inventor: JOHNSON JAMES W
IPC: B23K20/24
Filed: 1988-08-05
Abstract: A method of producing a metallic interface suitable for overlaying consists of exposing the area of an alloy combination to be overlayed to a temperature above its lower critical until an element reduced zone arises. This element reduced zone occurs by diffusion and more easily accepts element diffusion that takes place during overlaying. Accordingly, an improved interface, one that is more ductile and less prone to cracking, is produced.

Title: A target echo simulator
Inventor: MORRIS JOHN CHARLES
IPC: G01S7/537
Filed: 1988-11-23
Abstract: A target echo simulator for sonar uses a programmable delay (114,115 116) wherein samples (113) from a received sonar waveform (110) are sequentially written into a dynamic RAM 114. Write address is generated by means of a Write counter 116. In similar fashion a Read counter 115 generates a read-out signal, the read address being offset with respect to the write address such that an individual sample is delayed within the RAM by a time dependent on the offset and the clock (118) rate. The time delay is programmed into a ROM 120 and is so arranged as to simulate a circling "target". A spacing ROM 121 is provided to separate the signal samples in the memory and a sample amplitude structure (123) is superimposed such that a realistic highlight structure can be simultated for the target. In addition the spacing ROM is programmed such that the relataive separation of the samples is varied in dependence on the time delay such that Doppler shifts can be provided appropriate to the circling motion.
