Abstract: Heater assemblies for coal-burning stoves may have a refractory unit (14) providing a fuel supply hopper (20), an ignition zone (24) with which the hopper is connected, a grate (26) at the lower part of the ignition zone, and a combustion region (22) extending upwardly from the ignition zone and being substantially separated from the hopper by a baffle (18). Secondary air has been supplied uncontrolled to the lower portion of the combustion zone from outside the heater. 
     In the present invention, the grate (26) beneath the ignition zone allows primary air to flow into the ignition and combustion zones from a supply zone (28) beneath the grate, and secondary air flows from the supply zone to the combustion zone through at least one opening (30) in the refractory means. Various other developments disclosed include an air pre-heater, sealing (14.2,14.3) forthe refractory unit, and a cladding (12) for the heater.

Inventor: BENTLEY ALLEN EDWARD
IPC: B22F7/00
Filed: 1982-10-20
Abstract: The invention relates to metal strip and particularly to bi-metallic strip. The advantages of bi-metallic strip where each metal has characteristics to serve its intended function are well known but the production of such strip has, hitherto, required high capital costs and has predominently involved the welding together of the two metals by electron beam welding equipment or the like. Such techniques require high standards of cleanliness and frequently the welded composite strip requires subsequent mechanical finishing to form a smooth surface but even so the weld line cannot be visually eliminated. The object of the invention is to provide a bi-metallic strip which avoids the above disadvantages, which objective is met by a metal strip comprising two or more metals each in discrete longitudinal stripes with a longitudinal joint between adjacent stripes, said metals initially being in powder form and the powders simultaneously compacted to form a composite metal strip (6).

Abstract: The present invention relates to a three dimensional metal framework, designed for forming isothermic walls of buildings, which comprise an inner air cavity in form of a blade along one of its faces. This framework (9) comprises rectilinear and parallel rods (14) which are welded, in at least two parallel rows (14a, 14b), on sinusoidal wires (15) which extend in planes perpendicular to the rectilinear rods and whose tops (15a, 15b) are situated in two planes parallel with the two rows of rectilinear rods, the first row (14a) of rectilinear rods being furthermore slightly spaced apart from a first one of the planes containing the tops (15a) of the sinusoidal wires. The invention also relates to a constructional element built from this framework and comprising a bearing wall (4) and a heat insulating layer (5) both disposed between the two rows (14a, 14b) of the rectilinear rods of the framework (9) as well as two finishing coverings (2b, 3b) formed on the tops (15a, 15b) of the sinusoidal wires of the latter. An air cavity in form of a blade is therefore formed along one of the finishing coverings. The invention also relates to a process for constructing a constructional element of this type which constitutes an external wall of a house.

Les aimants sont orientes par rapport a leur epaisseur de maniere a distribuer leur flux sur des zones relativement etendues en evitant les regions a haute densite de flux. L'entrefer variable est obtenu au moyen de separateurs non magnetiques (55).

Abstract: The circuit for use in a primary time switch (PTSW), a secondary time switch (STSW), and a space switch (SSW) of a digital time-division switching system comprises a plurality of memory moduls (MUC). Each memory module comprises a memory unit (MEM), an address buffer (AB) for a first address, a time-slot counter (T-CTR) for a second address, an address selector (AS) for selecting either the first or second address, an input data buffer (lB), and an output data buffer (OB). In a write cycle, data from the input data buffer is written into the memory unit by either the first or second address signal, and in a read cycle, data is read out of the memory unit by either the second or first address. Selection of the first and second addresses is performed by the address selector, which is controlled by an address-selection mode switch circuit (Mo). The write enable mode of the memory unit is controlled by a write mode switch circuit (Mi). Such a modular construction can simplify the design and reduce the cost of a time division switching system.
