Title: Method of prestressing concrete plank filler joist - entails flattening arched reinforcement casting plank on foot and releasing flattening forces
IPC: E04B5/38
Filed: 1981-08-26
Abstract: The prestressing process is applied to a precast concrete plank incorporated in a universal slab, entailing the contra-flexure of a reinforcement cage (1), the casting of the plank (4) and the removal of the forces (P) maintaining contra-flexure. Initially the cage has an arched longitudinal profile and is flattened during counter flexing operation, its resistance to flexure giving rise to its prestressed condition. The timing of the removal of contra-flexure forces (P) depends on the concrete having gained sufficient strength and the plank is formed by a frame (3) associated with the cage.

Title: Method and installation for ethyl alcohol production from cereals
Inventor: KOLEV NIKOLAJ N
IPC: C07C29/00
Filed: 2001-11-08
Abstract: The invention is used in the produiction of ethanol for the food, pharmaceutical and chemical industries. The method includes grinding of the grain and saccharization of the starch in it, fermentation of the sugars produced to ethyl alcohol and alcohol rectification. By the method the saccharification of the starch is made by the only use of recuperated heat from the rectification, the consumption of bread yeast produced in the course of the process is reduced at the simultaneous yield of ethyl alcohol. The addition of extra quantity of water is avoided by its substitution with flour fine powder in the absorption of the ethyl alcohol by the carbon dioxide, thus reducing the steam consumption required for its purification during the rectification. The basic quantiuty of the ester-aldehyde fraction is removed from the fine flower powder in the alcohol concentration in it, wherein the rectification coefficient of the noxious components of the fraction is much higher, than in the concentration alcohol. 5 claims, 5 figures

Title: Composite material for covering slag disposal heaps of thermo-electric power plants, waste heaps and the formation of substrate layers for roads and sites
Inventor: DRAGANOV LILYAN
IPC: E01C7/00
Filed: 2003-07-10
Abstract: The composite material is designed for temporary or permanent surface and bottom laying of slag disposal heaps at Thermoelectric Power Plants for industrial and residential wastes, as well as for a substrate layer of temporary inner mining roads and in the lower structures of third class motorcar roads and sites. The composite material is a mixture of available inert fillers (wastes from Thermoelectric Power Stations - slag and ashes), hydraulic and air binders, plastifier and water. It is not impermeable but is resistant to water dilution, sputtering and leaching of heavy metals from it. Its compressive strength, or shearing strength, respectively, enables the running of transport vehicles on it, and subsequently - its excavation by means of chain excavator. The composition of the composite material, in wt.%, is as follows: slag and ashes from 90 to 80; cement from 10 to 15, lime 0-5, plastifier 1-2 from the weight of the cement and water. The material is prepared and laid by means of technology which is close to that for making and laying of cement-and-sand or concrete layer over a horizontal surface. Laying, levelling and compacting are made using standard constructional machinery.
