Filed: 1982-10-11
Granted: 1987-01-14
Abstract: An improved process for making video discs, which enables the molding of replicas having substantially higher signal-to-noise ratios during playback. One aspect of the invention extends the duration of a photoresist development process to yield developed recording masters having spaced information-bearing pits with unexpectedly steeper sidewalls. Another aspect of the invention forms metallic stampers using an initial vapor deposition step carried out in an extremely low pressure of about 1 x 10<-><6>  torr, to reduce oxidation and thereby improve conformity between the photoresist geometry and the stamper geometry.

Abstract: The directional control valve to apply to a hydraulic appliances working with uncompressible fluid, is composed of a cylindrical valve i.e. a sleeve 5 sliding in a cylindrical chamber 1, that acts as a cylinder to the piston 7 when its outside part B, or also its intermediate part A in an execution suitable to different application, penetrates inside the sleeve 5 or comes out of it. The control valve action is caused by the hydraulic fluid when the piston moves so that it comes out or by the fluid which the piston presses when, being the exhaust ports still opened, it moves in order to penetrate into the sleeve valve 5. The axial travel reversals of the control valve start every time the piston, by its circular edge 7c, gets a tightness touch with distributor's circular edge 5d. This control valve permits large tightnesses of exhaust and supply ports of hydraulic fluid so that the piston 7 avoid to do this by means of its lateral surfaces, as other control valve, and therefore the device is not subjected to wear. For its simplicity and very good functionality this directional control valve cuts manufacturing and maintenance costs; it can be, moreover, applied both to free gas recharging hammers and hammers directly actuated by under pressure hydraulic fluid.

Title: Process and device for manufacturing synthetic anhydrous calcium sulphate and pure hydrofluoric acid
IPC: C01B7/19
Filed: 1981-12-21
Granted: 1985-08-07
Abstract: In the production of synthetic anhydrous calcium sulphate and pure hydrofluoric acid, fluorspar is reacted with a mixture of sulphuric acid, oleum and a solution providing from the acid washing. Hence, a synthetic calcium sulphate is prepared, containing only the desired low content of CaF2, while the free sulphuric acid is completely neutralized, other desirable compounds being already present. The reaction is carried out in conditions such that no fluorsulphonic acid or very negligeable amounts of said acid reach the reactor and that the formation of new amounts of fluorsulphonic acid is actively prevented in the reactor. To this effect, on one hand the compounds CaF2 and the mixture-acid are introduced at a high temperature in the reactor and on the other hand the reactor is brought to a temperature such that the reaction initiates at about 100<o>C, thereby preventing the formation of new amount of fluorsulphonic acid. The gases coming out from the reactor are, in a first step, dried at a high temperature, then dusts are removed therefrom and finally in the last step, the gases are cooled.
