Title: Method for patching font file on computer
Inventor: KANG HYUNG-MIN
IPC: G06F3/14
Filed: 1993-09-16
Granted: 1997-01-08
Abstract: A font file fetch method for a computer fetches a font data in a hard disk on a resident program, the font data being used to transmit a data to a printer. Accordingly, the font file fetch method removes a limitation of a font quantity by a memory capacity limitation, thereby providing various fonts. The font file fetch method includes the steps of: calculating a cylinder, sector, and head information about a font file by snatching an interrupt(Int 13) when performing a memory resident program; requesting a corresponding font data when performing a main emulation program because of another interrupt(Int 17) while performing a main program; calculating a position information(Q) of a font file on the basis of both address(x) of a desired font data and a byte number(y) making the font data; calculating information(Q) about the font file, and calculating a position value which is positioned at Q-th position from an initial position of a sector by using information such as a drive about the font file, a cylinder number about a cylinder, a sector number about a sector, and a head number about a head; reading image data from a hard disk by substituting the position value as a parameter needed in the interrupt(Int 13); and transmitting the font image data to a main emulation program, and finishing a font fetch.

Title: Process for manufacturing lightweight cellular-expanded concrete masonry blocks
Inventor: VASILIU CONSTANTIN DAN
IPC: C04B24/00
Filed: 2002-04-15
Abstract: The invention relates to a process for manufacturing lightweight cellular-expanded concrete masonry blocks, the use of Ceton-type lightweight cellular-expanded concrete being included. The lightweight cellular-expanded concrete has the following composition (in mass units) : 100 parts cement of type I 42.5 R or having characteristics similar to that; 80 ... 250 parts of power plant ash; 0.5 ... 6 parts of surface active agent (AAS);1 ....4 parts of setting accelerator (Al). There are used as AAS: ethoxylated nonylphenol having 6 ... 40 moles of ethyleneoxide; maleic monoester or sulphosuccinic monoester, also derived from ethoxylated nonylphenol having 6 ... 40 moles of ethyeleneoxide; horny products (hair, horns, hoofs) hydrolized with sodium hydroxide. There are used as setting accelerator (Al): calcium chloride, sodium chloride, sodium sulphate or magnesium sulphate. According to the invention, the process consists in casting the lightweight cellular-expanded concrete of Ceton-type, onto the pallets, in overlapped layers, cut in verticale plane to usual sizes of masonry blocks, thus forming blocks piles or layers of about 1 m3, where they remain continuing their hardening until delivery, the manipulation and transportation are made with piles on pallets. The storage in pallets prevents water evaporation from the material, thus ensuring good conditions for hydration thereof and increasing the mechanical resistance.
