Title: Pressure regulating valve
Inventor: FERRAROTTI MICHAEL
IPC: G05D16/10
Filed: 2023-05-16
Abstract: A pressure regulating valve (10) includes an inlet (32), an outlet (34), an internal cavity (50), a first regulating window (52), and a second regulating window (54). Pressurized fluid enters the valve through the inlet at a first pressure, the fluid flows through the first regulating window into and through the internal cavity, and then the fluid flows out through the outlet at a second pressure which is lower than the first pressure. The second regulating window of the valve adds a leakage network that prevents pressure spikes within the valve. Further, the second regulating window is only utilized when the fluid pressure within the valve reaches a pressure limit, aiding in maintaining the desired regulated pressure.

IPC: H04R1/22
Filed: 1979-06-27
Abstract: The invention relates to an electro- acoustic transducer with a transducer plate which is clamped in the region of its edge by means of supports, is subjected to bending stress, and is provided with a piezo-electric layer and which, in the frequency response intended for transmission, (200 to 3,500 Hz approx.), in addition to the resonance peak resulting from the first harmonic of the transducer plate, also executes harmonics of a higher order. The aim of the invention is to contrive the fourth harmonic to be such that it does not have a disturbing effect. The aim is realised in that the fourth harmonic characterised by a circular node is displaced into a higher frequency range outside of the frequency range of interest in respect of telephone traffic to such an extent that a disturbing increase in sensitivity no longer occurs. Can be used in piezo-microphones.

Abstract: A circuit breaker having stationary contactors provided for all of the poles thereof. Movable contactors are provided for all of the poles in correspondence to the stationary contactors. Stationary contacts are provided on the end portions of stationary contactors and movable contacts are disposed on the end portions of the movable contactors. The movable contactors are movable from the stationary contactors by electromagnetic force to open respective circuits before the circuit breaker is opened by an overcurrent tripping device when large current such as short-circuit current flows. Holders adapted to hold the movable contactors of all of the poles are mounted on a common rotatable insulating rod, one of the holders being provided with a latch which is turnable around a rod provided on the holder. A slot is normally engaged with the latch, and when disengaged from the latch, a rod can be turned by the holder. A spring operates to engage the latch with the rod until an electromagnetic moment acting on the latch generated in any of the poles or the sum of electromagnetic forces generated in all of the poles reaches a predetermined value. When a predetermined value is exceeded, the movable contactors of all of the poles are simultaneously moved from the stationary contactors to open the respective circuits with the aid of the insulating rod and the holders.

Abstract: An apparatus for reheating stack gases leaving a plurality of scrubbers (34, 36) which uses water within an associated steam generator (12) asthe heating source. A heat exchanger (48) receives heat from the boiler water transferring it to a low pressure fluid which is circulated through heat exchange surfaces (38,40) downstream of each of the scrubbers (34,36). The flow of the high pressure boiler water is controlled in response to a temperature (176) of the low pressure fluid thereby providing a means for minimizing the flow and return temperature of the high pressure water. The high pressure water is taken from a circulating pump discharge (24) and returned to the circulating pump suction (12).

Abstract: A new liquid phase oxidation process in which a metal nitro complex transfers an oxygen atom from the nitro ligand to a substrate; especially such process conducted cyclically or catalytically using molecular oxygen as the oxygen source. Metal nitrosyl complex is formed as a coproduct together with an oxidation product of the substrate. In a catalytic process, molecular oxygen maintains a concentration of nitro ligand in the reaction mixture. In a cyclic process, nitrosyl ligand of the metal nitrosyl coproduct is reoxidized by molecular oxygen in presence of a monodentate base such as pyridine to nitro ligand; and the nitro complex, thus regenerated, can be used again to oxidize the substrate. In particular the metal is a Group VIII metal, especially cobalt and the nitro complex is pyridine cobalt nitro saloph. To accelerate oxidation of the substrate at given temperature, a cocatalyst is included in the reaction mixture, e.g., an organic complex of a transition metal such as Mo(VI), Pd(II), or a compound of a trivalent metallic element with an element of Group VII, such as the compound BF,.
