Title: Cleaning cold rolled steel - by applying a wetting agent and washing with high pressure water using a slot-type nozzle
Filed: 1977-03-09
Granted: 1985-04-02
Abstract: Cold rolled steel in the form of plate, sheet, strip or rod is cleaned to remove oil residues and metal (iron) particles by applying to the surface a wetting agent followed by spraying with water under pressure in such a way that a curtain of water is formed in a straight line across the whole width of the plate or sheet, using a nozzle of slot type, or several such nozzles.

Patent IT-1186339-B (IT)
Inventor: HOSYINORI UESUGI
IPC: G06F12/16
Filed: 1985-10-29
Granted: 1987-11-26
Abstract: A data processing apparatus has a central processing unit. The CPU causes a memory to store for example input sales data in units of department sales and other items. When a power supply is turned off, a battery supplies back-up power supply voltage to the memory to retain the storage contents of the memory. When the output voltage from the battery is decreased to a value which disables back-up of the memory, is latch circuit is set. The latch circuit is held in the set state until it is forcibly reset. Even if the power source is turned on again, the CPU inhibits sales data input to the electronic register in response to an output signal from latch circuit, thereby preventing errors in the electronic register caused by invalid data in memory.

Title: Earthquake resistant and draining wells for the stabilization for deep earth slides
Inventor: PIERFRANCO VENTURA
IPC: E02D/
Filed: 1989-05-19
Granted: 1993-02-02
Abstract: Proposal for the stabilization of earth slides in inhabited zones, characterized by slow movements, and by deep sliding surfaces, especially if located in proximity to resistant base layers, through the use of wells formed of covering rings with pre-set joints, resistant to seismic activity, and having draining action. The rings are used in deep pre-stressed anchorings, in such a way so as to render the zone seismically resistant to sliding movements.The structural system permits:- Cost reduction and improvement in stabilization benefits with respect to traditional consolidating structures, especially at sliding depths greater than 10 meters, and for zones of high seismic activity.- Execution of an auto-seeking operation, up to the establishment of an equilibrated condition of the earth mass in movement, which allows for shifts between the rings and the tie-rods to occur, until installation of the stabilization of the slide is established.- Reaching whatsoever sliding depths, blocking it by the diameter of the well, which at the final blockage of the joints, presents no distortions, and therefore offers integral resistance to seismic activity.- Direct drainage of the percolating waters by horizontally pre-arranged joints.
