A method of increasing the abrasion resistance of glass articles is disclosed. It has been found that by providing a vitreous substrate with a micro-roughened surface and an overlayer of dry lubricious organic coating, substantially increased lubricity and abrasion resistance is obtained. When the micro-roughened surface is provided by bonding a discontinuous distribution of discrete particulate m...

An explosion-proof battery vent and filler plug (10) is disclosed, which provides a flame barrier (16) to prevent external ignition of gas evolved from a battery during operation from causing ignition of the larger volume of gas within the battery itself, without simultaneously allowing a high rate of evaporation of the electrolyte. In accordance with the invention, the flame barrier means (16) is...

An automatic asparagus picking machine is disclosed comprising a chassis movable along a mound in which the asparagus are grown. The chassis has a picking tool which is mounted for horizontal and vertical translation at right angles to the direction of displacement of the chassis. The tops of the asparagus are back lit by a lighting system on one side of the mound and their images are picked up by...

Then a path guide d...

PURPOSE:To realize a memory bit error monitor device with the same structure even if the number of words is increased, by comparing the successively added and integrated result of every bit of parallel data, which are written in a buffer memory within a certain time, and the integrated result of data, which is read out in the next certain time, with each other for every bit. CONSTITUTION:A write m...

PURPOSE:To monitor bit error easily, by comparing the added and integrated result of the parity bit, which is generated from parallel data written in a data buffer memory in a certain time, with the similar result generated from read data in the next certain time. CONSTITUTION:A data buffer memory 1 is set to a write mode for a certain time, and write data 6 are written there, and a parity bit 8 i...

PREPARATION OF RAPIDLY SOLIDIFIED PARTICULATES Normally solid materials, e.g. metals or metal alloys, are provided as solid particulates, and preferably as fine spherical to almost spherical, as well as fiber-like, particulates, including solid particulates of a metallic glassy structure, by contacting a molten stream of the material, which at a temperature within 25 percent of its equilibrium mel...

Case 2715 MICROPROCESSOR WATCHDOG SYSTEM A watchdog system for a microprocessor uses the primary AC power source to initiate restart signals for the microprocessor. The microprocessor has an internal checking system which checks one or more memory locations for specific numbers or codes which are present in normal operation. Other additional checks may be made. If the check is satisfactory, the mi...

An aqueous solution of ethyl or propyl alcohol containing a basic compound such as KOH is shown to etch the surface of polyimide material up to 400 times faster than conventional aqueous KOH etching solutions.
