Title: Two-color electrophotographing method
Inventor: TSUSHIMA SHIYUUICHI
IPC: G03G15/01
Filed: 1982-06-10
Abstract: PURPOSE:To prevent the occurrence of hemming pictures, color mixing, leakage of latent images, etc., by forming each separate color picture by using a compound photosensitive body, in which two kinds of photoconductive layers having different spectral sensitivities are piled up in layer, and an ordinary photosensitive body. CONSTITUTION:A photosensitive body P1 is a compound photosensitive body in which the 1st photoconductive layer 2 which does not sense a specific color A and red light and the 2nd photoconductive layer 3 which senses the specific color A and red light are piled up in layer on a electrically conductive basic body 1. The surface of the photoconductive body P1 is uniformly negative-electrified and, secondarily, uniformly positive-electrified with a electrifier and the surface potential is lowered, and then, a two-color picture 6 of red and black is irradiated upon the white ground. At the red colored portion in the original 6, only the negative charege is erased on the layer 3 and the surface potential becomes positive. The white portion becomes 0 (zero). At the black colored portion, an almost equal potential is maintained and the portion is developed by a negative red toner 7 and transferred onto the copying paper. Then, a photosensitive layer 11 which senses red color is provided to photosensitive body P2. It is desirable to provide a photosensitive layer which senses all colors for the layer 11, if possible. The same original 6 is irradiated through a red-pass filter 13 and only the black portion is left with charge, and then, developed in black 14 and transferred onto paper 8.

The blank bar 1 to which tension is applied in the longitudinal direction is inserted intermittently into the space between the plate 2 and the roll 3 in the axial direction of the roll. The bar 1 is rolled transversely except in the groove 4 to form the step to the bar 1 in the transverse direction thereof.

Patent MX-9603650-A (MX)
Title: Thermoplastic security seal.
Inventor: GEORGOPOLOUS GEORGE
Filed: 1995-03-30
Abstract: A one piece molded thermoplastic, preferably polypropylene, high security seal for coin bags has a locking socket body from which a flag extends on one side and a rectangular flat elongated shackle extends on the opposite side via an intermediate flat member which has a tear band there across for selectively separating the member into two pieces to facilitate removal of the locked seal. The shackle has several locking circular segment teeth in two parallel linear arrays on opposite edges of the shackle adjacent to a tamper resistant flange at the member end. A locking sheet metal stamped insert has two sets of tangs defining two spaced tooth receiving openings in a socket locking cavity aligned with shackle receiving openings in the body. The body receives the insert transverse to the shackle insertion direction through a cavity side wall later sealed with a flap formed in the seal body. The locked shackle precludes removal of the insert should the side wall seal be tampered with. The locked shackle forms a closed loop passed through an aperture in the bag folded neck. A hook on the intermediate member forms a tear band tab and engages the bag neck in the seal locked condition.

Patent MX-9708933-A (MX)
Title: Measuring heating value using catalytic combustion.
Inventor: HEYDEN WILLIAM H VANDER
Filed: 1997-11-19
Abstract: The heating value of a sample gas is calculated by a microcontroller (12) from the heating value of a reference gas, and from flow ratios determined as the gas is consumed by catalytic combustion. In a preferred embodiment, chambers (5, 14) of fixed volume are charged to a predetermined pressure with a reference gas and a sample gas, respectively, and flowed to the catalyst at variable, changing flow rates as pressure decays. During the discharge cycle, a pressure transducer (13) senses the decaying pressure and this information is input to the microcontroller (12), which computes molar flow rates and which also senses the power level of combustion through a bridge circuit (24) in the catalytic apparatus (8, 10). Based on a ratio of molar flow rates and a ratio of corresponding power levels, a heating value of the sample gas is calculated by the microcontroller (12) and output to a visual display or other output device.
