Patent DE-3165575-D1 (DE)
Title: Hydraulic system comprising a locking device for maintaining a control valve in its working position
Inventor: STEPHENSON DWIGHT BRUCE
IPC: F15B13/02
Filed: 1981-10-16
Granted: 1984-09-20
Abstract: A hydraulic system includes a selective control valve and a cam member movable to selected positions for controlling a hydraulic cylinder powered by a pump. A follower is urged to a locking relationship with the cam by a hydromechanical mechanism to releasably hold the control valve in the selected positions. The hydromechanical mechanism includes a bore exposed to sump pressure and to pressure upstream and downstream from a metering valve in a passage interconnecting the pump and the control valve. A hollow apertured sleeve is movably mounted in the bore. An apertured piston is slidably received by the sleeve. A rod, engageable with the follower, extends through the piston and sleeve apertures. A first spring interconnects the rod and the piston and a second spring interconnects the piston and the sleeve. The sleeve moves to a preload position in response to a no-flow differential pressure between the sump and the passage to urge the follower via the rod towards its locking position. The piston moves in response to fluid flow through the passage to bias the follower toward its locking position. The piston and the rod move to automatically allow the follower to release from the cam when the function of the hydraulic cylinder is completed. Also, the sleeve and rod move to automatically allow the follower to release from the cam when system pressure in the passage is lost.

Title: A method and equipment to perform porosimetric analyses
Inventor: SISTI GIORGIO
IPC: G01N15/08
Filed: 1982-06-24
Granted: 1987-02-19
Abstract: This invention concerns a method and an equipment to perform porosimetric analyses, in particular following known analyses performed by a so-called mercury methods, wherein volumetric variations of mercury placed in a vessel are recorded, said variations being due to a mercury penetration into the pores of a solid sample placed in the same vessel under mercury pressure variations. 
<??>According to the invention further analyses are carried-out by lowering mercury pressure from a maximum value substantially to ambient value, following a predetermined law in function of time, for instance and preferably a pressure reduction at constant speed, and by simultaneously detecting the volume variations of mercury which comes out of the sample pores when pressure decreases. Said detection, when performed in relation and/or in addition to the traditional one during pressure increase, allows to obtain a pressure-volume mercury curve which provides further data on the porosimetric characteristics of the sample, in particular related to the shape of the pores of same.

Title: Regeneration cycle control system in a water conditioner controlled by a flow meter
Inventor: FLECKENSTEIN ANDREW
IPC: G01F15/07
Filed: 1982-01-21
Granted: 1987-08-06
Abstract: This invention relates to a control system for regeneration of a water treatment system in which a water meter monitors water usage and mechanically drives a water volume wheel to an operative position to call for regeneration when a predetermined volume of water has been treated and then automatically resets itself. A timer wheel driven by a motor is included within the control system such that the timer wheel and the water volume wheel coact to activate the regeneration cycle mechanism at a predetermined time after a predetermined volume of water has passed through the water meter. The mechanism is adjustable relative to the water treating capacity of the treatment system and the condition of the water being treated so as to be able to vary the predetermined volume of water treated which will call for regeneration.

Title: Plane die-cutting machine
Inventor: BARTESAGHI ANGELO
IPC: B26D1/30
Filed: 1982-02-08
Granted: 1988-06-23
Abstract: The invention concerns a plane die-cutting machine for die-cutting laminar material, of the type comprising a plane punch and an arc-shaped counter punch, which is controlled by moving means pressing the same against a work material inserted between it and the punch, said counter punch being simultaneously rotated around a line of instant-contact which runs along the punch. To avoid impacts between the reciprocally moving parts, the invention provides extensions integral to the punch and to the counter-punch, which maintain the contact between these latter for a portion of the reciprocal oscillatory movement outside the die-cutting area, so that said reciprocal oscillatory movement takes place with constantly contacting zones, like a blotter of blotting-paper.The die-cutting area is defined in such a way that, when the reciprocally moving parts contact themselves at the ends of said extensions, between the die-cutting parts a hollow space is left, which is sufficient for the passage of the laminar material under work.
Patent DE-3280417-D1 (DE)
Inventor: AGHNIDES ELIE P
IPC: E03C1/084
Filed: 1982-06-01
Granted: 1992-11-19
Abstract: The present invention is for a showerhead selectively operable to produce a plurality of different streams, enabling the user to select one form of large diameter stream, rich in bubbles, when the water pressure is high, and another large diameter rich stream full of bubbles when the water pressure is low. Furthermore, the user may select a spray instead of the bubbly stream. The invention is accomplished by having an upstream disc with chambers therein for directing the water downstreamwardly. In the path of the jets from said chambers there is a screened-disc which is rotatable selectively by the user and which has a number of openings therethrough. By bringing the correct opening below the jets, the user may select one of several different types of streams. One of the openings has two screens, one at the top and one at the bottom of the opening so that at low water pressures, there is abundant aeration which provides a rich outgoing stream of water. For a normal aerated showerhead, there is a hole with just one screen. Similarly, there is a third hole without any screen and which will produce a spray when that hole is located below the chambers. Similarly, the chambers may be duplicated around the upstream disc so that when the user selects a given form of stream, the type of hole that produces that stream will be receiving all of the water from all of the different chambers.

Pre-heated gases from sections (25) are fed to the top of the bed (114) also via the gas transfer section (34). Effluent gas from tubes (42) then re-enters transfer section (34) and flows into a pipe (44) which feeds the effluent gas downwardly into second catalyst bed (122). Effluent gas from the bottom of bed (122) flows upwardly between walls (124-126) separating bed (122) from the third bed (128), and thence into the top of bed (128). Product is removed from the bottom of bed (128) via pipe (68) and outlet (14). Low pressure drop and maximum conversion per pass since gases pass through all the catalyst in reactor.

Title: Metallurgical melting process, and direct current arc furnace therefor
Inventor: MOTTE JEAN-PIERRE
IPC: H05B7/144
Filed: 1984-04-27
Granted: 1988-06-16
Abstract: A direct-current arc furnace has a vessel with a floor and a cover, at least two vault electrodes projecting down into the vessel through the cover, and a hearth electrode exposed in the vessel generally in the floor below the vault electrodes. A scrap-metal charge is melted in this furnace by first energizing the vault electrodes with direct-current voltage of opposite polarity while displacing them downward through the charge from an upper position spaced relatively far from the hearth electrode to a lower position spaced relatively close to the hearth electrode and thereby passing an electric current through the charge to melt the charge and form a puddle of molten metal on the floor of the vessel at the hearth electrode. Then the hearth electrode is energized with direct-current voltage of a polarity opposite that of one of the vault electrodes and an electric current is passed through the charge between the one vault electrode and the hearth electrode to melt the charge and form a puddle at the hearth electrode at the floor of the vessel. Thereafter the vault electrodes are raised while continuing to pass an electric current partly formed as an arc between at least the one vault electrode and the hearth electrode until the entire charge is melted.
