Title: Process for the treatment of brown coal
Inventor: HARVEY FRANCES
IPC: C10F7/08
Filed: 1986-02-10
Abstract: The invention relates to a process for the treatment of brown coal, in which the coal is subjected to shearing forces in order to produce a plastic mass which can be converted by subsequent compaction and drying into a fuel of increased density and increased gross calorific value, which is characterised in that the water content of the coal amounts to more than 54% and the shearing forces are applied for less than 1h, shorter times being preferred, for example less than 30s. A preferred embodiment provides a continuous process in which the coal is treated in a machine in which it is successively subjected to shearing and extrusion stages in a continuous way. After drying, the extruded product yields the fuel of increased density and increased gross calorific value. The desired effect can likewise be obtained by treating part of a quantity of brown coal and mixing the treated part with the untreated remaining quantity.

Patent DE-3711211-A1 (DE)
Inventor: CHANG SUNG S
IPC: G01G19/00
Filed: 1987-04-03
Abstract: A postage meter which imprints [non-currency amount] indicia concorded with (but not directly symbolic of) postage value. The meter receives postage value determining information, such as mail piece weight, associated with particular mail pieces from apparatus (50) and comprises: a processor (126) for computing the corresponding postage; printing means (136) for imprinting the particular envelope with an indicium representing the but not directly symbolic of postage value; and accounting means (134) for accounting for the postage value thus expended. Because the range of postage value determining information is small compared with the possible range of postage setting information, meter operation is quicker and easier. In one embodiment the meter prints a validating indicia which confirms that the rates used to compute the postage value are valid. In another embodiment the postage value determining information includes information which characterises a batch of mail, for example as being entitled to a pre-sort discount. As described, in cases where the number of price ranges is small, the indicia representative thereof may all be accommodated on a single print wheel (whereas a direct digital representation of postal value would require a plurality of wheels). A significant increase in speed (due to only indexing said one print wheel between successive mailpieces) is said to be achieved. <IMAGE>
