Patent GB-2274956-A (GB)
Title: Run length data compression
Inventor: WILKINSON JAMES HEDLEY
IPC: H04N7/30
Filed: 1993-02-05
Abstract: A data compression apparatus is provided for compressing an input stream of n-bit data samples, with input sample values being notionally divided into groups containing a number of sample values. The apparatus comprises means 12 (fig.4) for generating a code word for at least each non-zero value input sample such that the code words for samples with values in each group have a most significant bit of one type in the same position, which position is different for different groups, and the sequence of bits of lower order than said most significant bit BS, is different in code words for samples with different values in the same group. A run-length counter 18 generates a run-length count dependent upon the number of samples in a run of zero value input samples terminated by a non-zero value sample and a means 17 geneates a position indicator indicating the position of said most significant bit of one type in the code word for the non-zero value sample terminating the run. A code word (e.g. huffman code) is generated in accordance with the output of the run length counter 18 and the position indicator PI, and the bits BS are appended to the code word so as to identify the particular value within each notionally divided group. <IMAGE>

Title: Switchable recirculation in a laundry drier
Inventor: WENTZLAFF GUENTER
IPC: D06F34/08
Filed: 1993-03-26
Abstract: A domestic laundry tumble dryer, of the kind having a rotatable tumbling drum 1, ducts which feed heated drying air to and discharge moisture-laden air from the drum and a heat-exchanger by which moisture from the discharged air can be precipitated by heat exchange with cooling ambient temperature air, has a changeover arrangement by which the moisture- lad en air and cooling air can follow alternative paths through the heat-exchanger and dryer, according to seasonal requirements. With crossover ducts 40, 41 in position ambient-temperature cooling air from intake 10 enters the heat- exchanger by inlet 7 and is subsequently discharged, while moisture-laden air from the drum 1 passes through link filter 16, enters the heat-exchanger by inlet 9 and is recirculated to the drum through a duct containing a heater. Replacement of crossover ducts 40, 41 by straight ducts 38, 39 causes cooling air from intake 10 to enter the heat-exchanger by inlet 9 and to leave it by the duct feeding the heater and drum. Alternatively changeover may be by flap valves in ducts between the intake 10, the drum 1 and the heat-exchanger inlets. <IMAGE>

Title: Transmitting enhanced digital video signal on compatible waveform
Inventor: CLARKE CHRISTOPHER KEITH PERRY
IPC: H04N7/24
Filed: 1994-02-09
Abstract: An enhanced digital television signal is transmitted within a conventional television waveform by modulating 22 the digital signals onto active picture area lines of the conventional waveform (such as IAL SECAM, NSTC). This may be achieved by first modulating a set of orthogonal waveforms, derived e.g. by the Walsh TransForm, with the digital signals and then transmitting the modulating orthogonal waveforms on the active picture area lines. A sync pulse generator 24 adds conventional Field/line sync pulses and optional colour burst to the transmitted signal. These may be used at the receiver, but are not necessary. <IMAGE>

Title: A liquid-phase heteroepitaxy method
Inventor: HANSSON PER-OVE
IPC: H01L21/208
Filed: 1994-03-24
Abstract: To produce a layer by liquid-phase heteroepitaxy a molten metal serving as the solvent is saturated at a first temperature with substrate material and compounded with layer material. The solution and the substrate are then separately "overheated" to a second, higher temperature and then brought into contact with each other. Due to the overheating a negative thermodynamic driving force results for the epitaxy which compensates the positive driving force for the epitaxy at least in part due to the different interfacial energies between layer material and solution and substrate material and solution. The degree of overheating determines the resulting total driving force for the epitaxy which may be reduced to zero. Very thin layers, down to a monolayer thickness may be grown in this way from the solution with a layer thickness exact to a monolayer with no dislocation. The preferred solvents are Ga and In, the layers GaAs and InGaAs and substrates AlGaAs and InP.
