Abstract: 621,351. Gas turbine and air-conditioning plant. GARRETT CORPORATION. Feb. 20, 1947, No. 5035. Convention date, Aug. 19, 1946. [Class 110(iii)] In an air-conditioning plant for an aircraft cabin 10, a gas turbine 17 drives two air-compressors 32, 34 and delivers its exhaust to a heat-exchanger 52. The compressor 34 circulates air in ducts 50, 44 which transfer heat from the exchanger 52 to an exchanger 37. The compressor 32 delivers combustion air for the turbine and air for the cabin. The latter air is passed through the heat-exchanger 37 and expanded down to the desired pressure in a turbine 26, provided with a valved bye-pass 42. Power is taken off the shaft 25 to drive a combined D.C. and A.C. generator 62. Hot gas for de-icing purposes is taken off past a valve 57 and its temperature is controlled by means of a valved bye-pass 58, 59. When the cabin air is to be heated, valves 67, 68 are shut and valve 69 open. When it is to be cooled, valves 67, 68 are open and valve 69 shut so that atmospheric air is drawn by the compressor 34 past the valve 68 and through the heatexchanger 37.

Title: Ringing trip circuit
IPC: H04M19/02
Filed: 1973-02-01
Abstract: 1386193 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 1 Feb 1973 [8 Feb 1972] 5079/73 Heading H4K A ring trip circuit includes a resistor R1 connected in a wire of a subscriber's line, the potential across the resistor being coupled to the base of a transistor T1 via a low pass filter F, and the arrangement is such that ringing current alone flowing in resistor R1 is prevented from triggering transistor T1 due to the filter F whereas a direct current flowing in resistor R1 causes transistor T1 to turn on, thereby operating ring trip relay O. Diode Di1 is a threshold diode used to protect transistor T1 against excess line voltages and diode Di2 prevents reverse currents in the collector-base junction of transistor T1. More particularly transistor T1 is turned on when the combination of direct current and ringing current in resistor R1 makes terminal A1 negative to charge capactior C3, thereby turning on transistor T2. When terminal A1 positive, transistor T1 turns off, capacitor C3 discharges the keeping transistor T2 conducting and in turn causing transistor T3 to conduct and operate the ring trip relay O.

Abstract: 231,998. Jauvert, P. M. March 6, 1924. Refrigerating, compression machines for.-The flow of refrigerant from the condenser to the evaporator is regulated automatically by a valve actuated by a diaphragm subjected to the pressure of a medium which expands upon congelation brought about by the low temperature of the vapour returning to the compressor. The condenser 15 and evaporator 26 are of annular form and are arranged concentrically upon a compressor casing 4. The condenser and compressor are cooled by water circulating through a jacket 21, and the evaporator cools brine or other medium circulating around it. The regulating device comprises a casing 31 fitted with two diaphragms 37, 37<1>, the upper diaphragm 37 carrying a needle valve 38 to control the flow of refrigerant entering by a pipe 30<1> and leaving by a pipe 30. The chamber 40 between the diaphragms communicates by a pipe 41 with a jacket 42 surrounding the pipe 32 connecting the evaporator with the compressor chamber 4. The jacket 42, pipe 41 and chamber 40 contain a liquid such as salt water which congeals when the returning vapour is abnormally cold and by its expansion acts on the upper diaphragm to close the valve 38. Adjustment is effected by means of a screw 31<1> engageable with the lower diaphragm to vary the normal capacity of the space 40. In the event of obstruction of the valve due to corrosion or freezing, the stoppage of the flow of refrigerant results in thawing of the congealable liquid and consequent opening and clearing of the valve.

Title: A process for the production of esters of allyl-type alcohols
IPC: C07C69/02
Filed: 1948-02-26
Abstract: Esters of carboxylic acids with allyl-type alcohols are prepared by esterifying the acid or its anhydride with the alcohol in the presence of an added ether of the said alcohol.  This practice reduces the tendency for ether formation.  Alcohols to be used conform to the formula <FORM:0646052/IV (b)/1> in which R is an alkyl group or a hydrogen atom and preferably have 3-5 carbon atoms in the molecule so that the corresponding ethers have from 6-10 carbon atoms in the molecule.  Alcohols specified are allyl, methallyl, crotyl, angelyl and tiglyl alcohol, ethers being diallyl, dimethallyl, dicrotyl, diangelyl, ditiglyl, allyl methallyl and crotyl methallyl ethers, symmetric ethers being preferred.  Any esterifiable carboxylic acid may be used particularly di- and polycarboxylic acids and acids with not more than 18 carbon atoms in the molecule.  Many acids are specified including formic, n-butyric, benzoic, lauric, oleic, ricinoleic, maleic, phthalic, oxalic, hemimellitic, trimellitic, and prehnitic acids.  Anhydrides of acids specified include those of acetic, succinic, benzoic and phthalic acids.  A partial ester of a polycarboxylic acid, e.g. monoallyl phthalate, may also be used as the acid reactant.  The reaction may be conducted in the presence of an azeotrope former, preferably the ether corresponding to the alcohol reacted.  Catalysts may also be present. Generally a small excess of alcohol is employed and the azeotrope former is used in volumes of 0.1 to 0.5 volumes of alcohol. Temperatures instanced are up to 160 DEG  C.  In an example, 2.5 mols. of allyl alcohol are esterified with one mol. of phthalic anhydride at 140 DEG  C., with sulphuric acid as catalyst and excess diallyl ether as azeotrope former and results obtained compared with those when using benzene as azeotrope diluent, more diallyl ether being obtained when benzene is used.
