Patent GB-2075295-A (GB)
Title: A single-supply ic digital-to-analog converter for use with microprocessors
IPC: H03F1/32
Filed: 1981-02-10
Abstract: A single-chip 8-bit digital-to-analog converter (DAC) with bipolar current sources, an output buffer amplifier for developing an output voltage and a regulated reference for producing a calibrated output is operated by a single-voltage supply, e.g. +5 volts. The buffer amplifier includes means providing for driving the output voltage virtually to ground level when the DAC output is zero. The current sources comprise a single-transistor cell driven by an I<2>L flip-flop circuit, and the reference supply is merged with the reference transistor circuit regulating the DAC current levels, both aiding in reducing required chip area. On the amplifier, transistor Q40 has an additional element C3 which serves as an invalid mode collector when the amplifier output nears zero to prevent saturation of the transistor. <IMAGE>

Title: Metallurgical processes utilising particular fuels
IPC: C21B13/00
Filed: 1981-03-30
Abstract: In processes particularly for the manufacture of steels, alloy steels and ferrous alloys fuel consumption is reduced and efficiency improved by using in the oxy-fuel or air-fuel burner a fuel (referred to as an "X-type" fuel) which has an exothermic heat of decomposition or which has only a zero or a very small endothermic heat of decomposition. The invention also relates to an oxy- fuel or air-fuel burner for use in a metallurgical process using an X-type fuel, which burner uses as coolant for the burner walls and tip the fuel used in the burner.

Patent GB-2095519-A (GB)
Title: Energy band discriminator
IPC: H04B3/23
Filed: 1982-03-03
Abstract: Energy in a received signal is distinguished as being whole band energy or partial band energy in an energy discriminator (103) by comparing an average value of the received signal to a modified magnitude value of the received signal. When the modified magnitude value exceeds the average value, the received signal includes whole band energy, otherwise the received signal includes only partial band energy. This technique is employed in an echo canceler (100) to enable updating an echo path estimate during intervals that the received signal includes whole band energy and to inhibit updating of the echo estimate being generated when the received signal includes only partial band energy.

Patent GB-2126822-A (GB)
Title: Video signal processing
Inventor: CHILDS IAN
IPC: H04N11/24
Filed: 1982-07-30
Abstract: A video signal is subjected to combined horizontal/vertical, horizontal/temporal or horizontal/vertical/temporal filtering to improve the horizontal resolution at the expense of diagonal and/or temporal resolution. The signal is passed through a comb filter 8 with attenuation frequencies at multiples of line, picture or field frequency (as the case may be) and then sampled 10 with a sampling rate having a half- line, half-picture or half-field offset. High frequency components above the pass band of the transmission channel are thus carried as alias components in the gaps created by the comb filter. At the receiving end (Fig. 2) the HF components are regenerated by a similar sampler (21) followed by a comb filter (22) which removes these alias components. The process is limited to a high frequency section of the signal in order to provide a substantial degree of resolution enhancement whilst preserving compatability with existing receivers in the low frequency part of the signal. The process may be used in conjunction with systems where the high frequency luminance is transmitted out-of-band. <IMAGE>

Filed: 1983-06-06
Abstract: An atomic absorption spectrophotometer uses magnetically encoded hollow cathode lamp assemblies (HCL1-HCL4) corresponding to their resonant line(s), the code being representative of one or more atomic elements. The code is read by corresponding magnetic code readers (MCR1-MCR4) whose outputs are fed to a microcomputer (MCP) which includes a microprocessor  mu P) a read-only memory (ROM) and a read-write memory (RAM) to identify the elements. The read only memory (ROM) contains wavelength information at a location therein associated with each element by means of which the microprocessor causes the correct operating current to be supplied by the lamp power supply (LPS) and causes the monochromator (MN) to be driven to the appropriate wavelength by the monochromator wavelength control (MWC).   The magnetic code may be on a label directly affixed to the lamp envelope or on a separate card attached to the lamp, the card being inserted into a magnetic card reader. <IMAGE>
