Patent GB-2100092-A (GB)
Title: Compatible transcodeable and hierarchical digital TV system
IPC: H04N7/01
Filed: 1982-05-10
Abstract: A transcoding arrangement transcodes signals sampled at a first frequency into second signals clocked at a second frequency. The first and second frequencies are selected so that their quotient is the ratio of integers. This results in recurrent blocks of samples having integer numbers of input samples and new output samples. A transcoder uses delay elements to form successively delayed samples of the input signal. Subtractors form difference signals representing the amplitude difference between successive delayed samples. Multipliers coupled to the subtractors multiply the difference signals by a running variable multiplicand to form weighted difference signals. The running variable is related to the effective position of the new sample being formed within a transcoding block of samples. The weighted difference signals are summed in an adder to form the new sample values. The arrangement permits transcoding between video signals sampled at different rates such as national standards for PAL and NTSC and any worldwide television standard which may be adopted. <IMAGE>

Title: Battery charging system
Inventor: LOWNDES M W
IPC: G01R31/36
Filed: 1983-11-25
Abstract: A microprocessor based monitoring/charging system for the traction battery 10 of an electric vehicle evaluates the state of charge and displays it on a dashboard mounted meter 64, interfaces with a traction motor control system 20, and controls a charger 22. The A battery is divided into nine 24V sub-packs. During both discharge and recharge, the battery current is integrated to obtain a value representing the charge withdrawn. During charging, in a first phase and charge withdrawn is replaced whilst progressively reducing the charging current in accordance with the charge withdrawn value. At the end of the first phase the sub-pack having the lowest voltage is found and, during a second phase, the battery is charged until the rate of voltage rise of the this sub-pack falls below a critical level. The battery is then given an overcharge, and at periodic intervals the battery is given an equalising charge. <IMAGE>

Title: Radiant tube for gas burner
Inventor: COLLIER DAVID WILLIAM
IPC: F23C3/00
Filed: 1984-01-09
Abstract: A burner 5 is located within a flame tube 2 arranged coaxially in an outer tube 6 with a closed end. Air enters through inlet 15 and exhaust gases flow between the tubes to exhaust duct 10. To reduce heat transfer to the flame tube 2 adjacent to the burner 5, vanes 19 are associated with the burner which cause combustion air to swirl before it mixes with gas from the burner and produce a vortex which encourages the gas to flow, and the flame to extend, centrally of the flame tube adjacent to the burner, and also cause air to surround the flame adjacent to the burner. In one embodiment the air is divided by a shroud surrounding the burner. The shroud causes the air to converge towards the central axis of the flame tube as it approaches the vanes. The flame length can be varied by adjusting the distance between the shroud and the burner. <IMAGE>
