Title: Control mechanism for gas compression means
IPC: F25B49/02
Filed: 1960-05-17
Abstract: 939,304. Centrifugal compressors. CARRIER CORPORATION. May 17, 1960 [May 28, 1959], No. 17451/60. Class 110 (1). [Also in Groups XIII and XXIX] A compressor subject to reverse flow upon termination of operation has a valve in the suction line and valve control means operated by gas from the compressor discharge to position the valve so as to offer maximum resistance to flow upon termination of operation of the compressor, the valve control means being operated by gas from the discharge of the compressor. The invention is described with reference to a refrigeration system in which a centrifugal compressor discharges refrigerant gas to a condenser from which the liquefied refrigerant flows to an economiser and evaporator from which it is withdrawn in gaseous form by the compressor. The compressor has a series of adjustable inlet guide vanes which are actuated by a rack 28, Fig. 2, attached to a piston 32 mounted in a cylinder 30. Lubrication oil is supplied to the cylinder 30 through a supply line 31 and branch lines 36, 38 containing check valves 40 and three-way control valves 42, 44. A restrictor 46 enables the flow rate to the cylinder to be maintained substantially constant. The valves 42, 44 are controlled by solenoids 48, 50. A line 57 from the compressor discharge pipe and connected to the line 38 is controlled by a valve 58 operated by a solenoid 59. A solenoidoperated valve 80 vents the line 36 to drain. Solenoid 59 is controlled in conjunction with the motor control switch 73, Fig. 3, of the compressor motor so that valve 58 is closed when the compressor is in operation. When the compressor motor is shut down, the valve 58 is opened to allow gas from the compressor discharge to enter the cylinder 30 and cause the compressor inlet guide vanes to be closed. Solenoids 48, 50 are de-energized at the same time. Valve 44 is then closed to prevent flow to the drain 53 and a valve 42 opened to allow flow to the drain. The solenoids 48, 50 are also controlled by a temperature control 71 responsive to the temperature of the medium cooled in the evaporator. If this temperature is above a predetermined value, the valve 42 is opened to allow lubricant to enter the cylinder 30 and open the compressor guide vanes to increase the capacity of the compressor. This will result in a reduction of the temperature of the medium being cooled which will open the circuit through the solenoids 44, 48 and valves 44, 42 operated so as to move the piston 32 to the left and close the guide vanes.

Patent GB-905898-A (GB)
Title: Improvements in or relating to electrolytic capacitors
Filed: 1958-12-09
Abstract: Boric acid esters are made by heating boric acid or a lower p  boron ester with a lower monohydric alcohol containing not more than 7 carbon atoms under reflux and removing water, preferably by azeotropic distillation with butanol or benzene, to such an extent that at least 2.4 moles of water per mole of boric acid, are removed from the mixture, so that the resultant mixture contains not more than 0.6 grams of free water per gram-atom of boron.  Suitable alcohols are methanol, ethanol, 2-methoxyethanol, isopropanol, t-butanol, tetrahydrofurfuryl alcohol or benzyl alcohol.  The benzene is distilled off and the ester may, if desired, be purified by fractional distillation.  From 1.2 to 20 moles of the same or different lower monohydric alcohol may be added for each gram-atom of boron and the mixture at least partially neutralised with from 0.02 to 1.0 gram-ion of the ammoniu, an alkali metal or alkaline earth metal kation for each gramatom of boron to form an electrolyte for an electrolytic condenser (see Group XXXVI).  It is believed that the excess alcohol reacts with the ester to form a tetra-alkoxo acid HB(OR)4 which is at least partially neutralised by the kation.  The electrolyte is probably a mixture of alcohol, ester, alkoxo acid and salt.  The neutralisation may be effected by direct addition of alkali metal, alkaline earth metal or dry gaseous ammonia, or an alkali metal or alkaline earth metal alcoholate, or alternatively the appropriate hydroxide or aqueous ammonia may be added before esterification so that water of neutralisation is removed with water of esterification.  In examples, (1) boric acid is esterified with ethylene glycol while 2.4 to 3.0 moles of water are removed azeotropically with butanol, the glycol ester is re-esterified with a lower alcohol such as methanol, the mixture is distilled, a further amount of the alcohol is added and then gaseous ammonia, alkali metal or alkaline earth metal are added; (2) boric acid and 2-methoxyethanol are refluxed distilled in the presence of benzene until water removal is complete, excess benzene is distilled off and the ester may be purified by distillation.  The ester is then treated with ammonia and/or one or more alkali or alkaline earth metals, one or more lower alcohols being added.
