Title: Data processing apparatus with parallel encoded priority
IPC: G06F9/46
Filed: 1980-10-07
Abstract: In a data processing system having a number of units 34,35,36 each unit includes a parallel encoded priority circuit 615-618. The parallel priority circuit are interconnected by a common encoded parallel priority bus which carries parallel priority signals indicating the priority level of any unit requesting access. If a unit requesting access has a lower priority than indicated on the parallel priority bus, that requesting unit is inhibited from obtaining access. If a requesting unit has higher priority than the signals on the parallel priority bus, that unit in turn causes the priority bus to be switched to the higher priority level. After the signals on the priority bus are switched to a higher priority level, any requests of a lower priority unit will not be honored. Certain of the priority circuits having the same priority level may be connected in a serial priority chain to resolve requests among those circuits. <IMAGE>

Title: Digital television signal processing
IPC: G06F11/10
Filed: 1981-03-23
Abstract: An error-correction format for transmitting digital television signals comprises segments of data, which segments may for example represent 48 successive horizontal lines of a television field. The segment comprises, for example, data groups n to n+23 and a final group n+24 which forms a vertical parity check (VPC) group. Each of the data groups n to n+23 comprises m blocks, and each block comprises a synchronization and address sub-block followed by s data sub-blocks, each data sub-block being followed by respective inner code protection bits (ICPBs) for providing error protection for the immediately preceding data sub-block, and finally followed by a cyclic redundancy check (CRC) code for providing error protection for the s data sub-blocks in the block. The vertical parity group n+24 is just the same in format as the other groups n to n+23, but each sub-block thereof is made up vertical parity check words which form an outer error correcting code in place of data words.

Title: Corrosion inhibitors
IPC: C08F8/30
Filed: 1981-08-07
Abstract: A corrosion inhibitor comprises particles of an organic anion-exchange resin having nitrite anions chemically bound thereto.

Title: Floor panels
IPC: E04F15/04
Filed: 1981-11-25
Abstract: A heavy duty industrial floor panel is made of keroin or like timber in relatively thin rectangular sections 21 bolted together with the long sides of the rectangle in abutment into a square panel. The thin section, as compared to the standard 3 sec  x 3 sec  section (7.6 cm x 7.6 cm) makes the kilning process much more effective at stabilising the panel against shrinkage, thereby avoiding the need routinely to tighten up the bolts. The lengths are also rebated to give a tongue and groove effect for added support. <IMAGE>

Title: Method of operating a machine tool
Inventor: MCMURTRY DAVID ROBERTS
IPC: G05B19/401
Filed: 1982-09-14
Abstract: The machine tool is a machining centre having an angularly positionable tool spindle 16, a work table 11 movable relative to the spindle, and a surface-sensing probe 25 mountable on the spindle for measuring dimensions or positions on a work piece situated on the table. The probe senses a surface when the latter lies a small distance ("the probe offset") away from the spindle axis. The method comprises providing on the workpiece a bore 24 defining opposite test surfaces -DX and +DX. The mid-point between the test surfaces has a known nominal position but an unknown actual position. The method further comprises operating the machine in a specified way to measure the test surfaces, the operation including rotating the spindle through 180 DEG  between certain of the measuring operations. The measurements are then used for computing the probe offsets and the distance ("the work offset") between said nominal and actual positions. <IMAGE>

Title: Inverter firing control with compensation for variable switching delay
Inventor: JESSEE RALPH DONALD
IPC: H02M7/5387
Filed: 1983-08-23
Abstract: A pole switch firing control for a pulse width modulated inverter controls pole switch operation under steady state operating conditions such that the inverter output duplicates a reference signal waveform P, Fig 1A, after a fixed time delay T. Pole switch operating time D1, D2, D3, Fig 1D, for a given pulse in an inverter output cycle is measured and subtracted from a fixed time interval T to get a delay time TS1,TS2, TS3, Fig 1E. In the succeeding output cycle Fig. 2, the corresponding pulse is produced by initiating the pole switch operating sequence after the delay time TS1, TS2, TS3, thereby causing the pole switch to operate a fixed time T following the reference signal P. <IMAGE>

Title: Manufacture of ceramics
Inventor: ROSSMANN AXEL
IPC: B32B18/00
Filed: 1984-07-23
Abstract: Ceramic components are made by forming, prior to sintering, a green ceramic matrix with at least one fibre layer consisting of similar ceramic material in or on the matrix with no, or only partial, infiltration of the matrix material into the fibre layer, and then sintering the matrix and fibre layer together. The matrix and fibre layer may be formed together by putting the latter in a mould and slip casting the matrix, or by isostatic pressing the matrix and fibre layer(s) together in a mould. Owing to the partially homogeneous union between similar composite materials the reinforcing fibre layer produces a crack-stopping and fragment-containing effect in the event of rupture of the ceramic component.
