Title: Improvements in or relating to compressor regulators
IPC: F04B49/02
Filed: 1939-02-10
Abstract: 524,958. Regulating gas compressors. INGERSOLL-RAND CO. Feb. 10, 1939, No. 4497. Convention date, Feb. 16, 1938. [Class 8 (i)] [Also in Group XXIX] A compressor 7 is driven by an internal combustion engine 1 which has a speed governor 25 loaded by a spring 33, the compression of which is adjusted by a lever 67 engaging a plunger 59. The lever 67 is connected by a link to a bellows 83 in a chamber 74 which is connected through an orifice 78 to the receiver. Receiver pressure acts on a diaphragm 97 connected to a rod 102, which is connected to the bellows 83 by a lever 87 carrying a valve 114 cooperating with an orifice 86 which is larger than orifice 78. As the receiver pressure increases, the valve 114 opens the orifice 86 and releases the pressure in the chamber 74 until at a predetermined high pressure the governor is set to a minimum speed control. If the pressure increases, the receiver pressure acting in a member in casing 179 causes a valve in the compressor inlet 9 to close gradually, until it is shut at a predetermined maximum pressure. In a modification shown in Fig. 4, the rod 71 is connected to a hollow rod 130 connected to a bellows 128 in a chamber 118 connected by an orifice 123 to the induction pipe of the internal combustion engine. The rod 130 has an orifice 133 which is opened and closed by a lever 138 connected to a rod 141 which is secured to a diaphragm 143 exposed to receiver pressure. A spring 158 extends between the end of the lever 138 and a collar 157 which when the pressure is rising engages a recess 168 in the lever 138 until the predetermined high pressure is reached, when it moves to the other side of the projection 162. The lever 138 is held in this manner until the receiver pressure has fallen to a low value, when the collar moves again to the recess 168.

Abstract: 1531591 Bacteria used in sewage treatment GENERAL ENVIRONMENTAL SCIENCE CORP 10 Feb 1976 [21 Feb 1975] 5130/76 Heading C1C [Also in Division C6] An aqueous suspension of bacteria rendered dormant, useful in the treatment of waste waters and sewage, is prepared by a method involving (a) growing bacteria under aerobic conditions in a sterilized aqueous medium by adding thereto at least one species of Pseudomonas bacteria which is capable of enzymatically reducing nitrate to nitrogen and at least one species of Rhodopseudomonas bacteria capable of photosynthetically forming red pigment; (b) dissolving in the bacteriacontaining medium a sodium or potassium sulphide (or mixture thereof) in an amount, usually in the range 0.07 to 0À3 grams per litre, sufficient to render the bacteria dormant but capable of being reactivated without a significant percentage being destroyed; and (c) exposing the sulphide-containing medium to light, under anaerobic conditions, for a period of time sufficient to cause photosynthetic red pigment to develop in the Rhodopseudomonas bacteria. Step (c) is continued for a period of substantially 24 hours under fluorescent lighting. In the treatment of sewage by the mixed culture, ammonia is converted to gaseous nitrogen via nitrate and concomitantly with the nitrate reduction, sulphur is converted to sulphate and acetate to gaseous carbon dioxide. Noxious odours are thereby eliminated. A preferred mixed culture includes six species of bacteria viz. one Bacillus (Gram positive, spore-forming, rods), one Rhodopseudomonas (photosynthetic, non-sulphur purple, Gram negative, non spore-forming, rods), and four Pseudomonas (Gram negative, non spore-forming, rods) at least one of which is capable of reducing nitrate to nitrogen or nitrous oxide gases. The mixed culture can be used in the treatment of waste waters and sewage generally, many specific applications being mentioned, including grease traps and waste from restaurants and slaughterhouses.
