Patent DE-3382638-D1 (DE)
Inventor: STOREN HARALD
IPC: C01B21/20
Filed: 1983-08-03
Granted: 1992-12-17
Abstract: The present invention relates to a method for transference, cooling and compression of nitrogen oxide-containing gases, In critical sections of the unit for such processes it can be formed salt deposits, but such deposits can be removed or prevented by maintaining a water vapour pressure which lies above the vapour pressure of the salt deposits at the existing temperatures. The prescribed water vapour pressure is maintained only by cooling the gas in at least one cooler and/or by cooling the gas directly by injection of liquid into the gas. The gas can be divided into several streams (2, 3,4) and cooled indirectly in two coolers (B, C) and directly in one cooler (A). The gas streams are mixed together in pipe (5) after the cooling step and transferred to compression (6). The condensate from the indirect coolers (B, C) can be utilized by the direct cooling. Salt deposits can be removed/ prevented without supply of extra energy, water vapour or liquid. The method can be adapted to existing plants without large alteration of these.

Title: Hydraulic system with a pump, a valve, a supply pipe and a control pipe
Inventor: MILLER JAMES ANTON
IPC: B62D5/06
Filed: 1984-08-07
Granted: 1988-06-16
Abstract: A load sensing hydraulic system is disclosed which essentially eliminates kickback from a feedback mechanism contained in a manually operable control valve which in turn is fluidly connected to a hydraulic function. The system includes a power on demand pump fluidly connected between a reservoir and the control valve for supplying pressurized fluid to the hydraulic function. A load signal line is also connected between the control valve and the pump which serves to transmit pressure signals, which are generated by loads acting on the hydraulic function, to the pump for controlling the pressurized output thereof. A load signal control valve is positioned in the load signal line and is fluidly connected to the discharge side of the pump. The load signal control valve is capable of sensing pressure variations between the fluid discharged by the pump and the upstream fluid present in the load signal line. As soon as the control valve senses that the pressure of the fluid discharged by the pump is less than the upstream pressure of the fluid in the load signal line, it moves to block off fluid flow from the hydraulic function and thereby eliminates kickback on the manually operable control member.

Title: Valve cap for tyres incorporating means for indicating pressure-loss
Inventor: ACHTERHOLT RAINER
IPC: B60C23/00
Filed: 1986-12-23
Granted: 1989-09-07
Abstract: A valve cap adapted to be screwed onto the valve of a pneumatic tire gives a pressure drop indication. To this end the valve cap comprises a deflectable diaphragm which separates the housing interior into a first chamber adjacent a transparent section of the closed housing end portion and a second chamber which is in communication with the tire interior through a port formed in a transverse housing wall and through the open tire valve. When the valve cap has been tightly screwed onto the tire valve and the tire valve has been opened, the desired tire pressure will be built up in both chambers. Upon closing of the second chamber a reference pressure corresponding to the desired tire pressure will prevail therein. Any reduction of the tire pressure relative to the reference pressure will cause the diaphragm to converge towards the transparent housing portion, thus serving as an indication.

Title: Implement attachable to a tractor
Inventor: FRANET ROGER
IPC: A01B59/042

Granted: 1989-09-28
Abstract: A drive line (26) for an implement (14) attachable to a tractor (10) includes two double cross bearing universal joints (32 and 34). During turns between passes over crop the power delivered by the line must turn through a working angle as large as 90 DEG . but for such a tight turn each joint turns the power through two angles of only 22 1/2 DEG  thus enabing full power to be used between passes without undue wear. The implement (14) is attached to lower links (18) of the tractor (10) by way of a yoke (16) which in turn is connected to a drawbar (12) of the implement (14) via a pair of channel-shaped supports (20, 22) rigid with, and at right angles to, one another. One support (20) receives the forward end of the drawbar (12) in its channel and is connected thereto by a vertical pivot pin (21). The other support (22) similarly receives the yoke (16) to which it is connected by a horizontal pivot pin (23). There is thus provided a drive and an arrangement for attaching the implement (14) to the tractor (10) which permits tight turns to be made efficiently.

Granted: 1991-09-05
Abstract: To recover useful solvent held together with water vapour in air discharged from a process, the waste air is first fed via a condensation heat exchanger to a chamber wherein application of counter-pressure by a blower causes much of the solvent vapour to condense. The air then passes through a molecular sieve adsorbing both moisture and the solvent residues. Sieve regeneration is by heating at two different temps. At the first temp., water vapour is liberated, and at the second temp. the solvent vapour which condenses in a second heat exchanger. Twin adsorption beds may be held in a single container. Dry and solvent -free air is finely discharged into atmos.
