Title: Device for detecting the axial movement of a rotating shaft
IPC: G01B13/00
Filed: 1975-01-22
Abstract: 1491803 Bearings GENERAL ELECTRIC CO 22 Jan 1975 [14 Feb 1974] 2759/75 Heading F2A [Also in Divisions F1 G1 and G3] A device for measuring axial or thrust bearing wear of a rotating shaft such as a turborotor 15 and for shutting the main valve of the turbomachine when excessive wear occurs comprises a follower piston 23 which moves to maintain a constant fluid gap between a spring pressed slidable piston nozzle 33 and the rotor 15, a slidable valve member 51 operable by the piston to cut off fluid pressure from supply pipe 75 to either of outlet ports 57a or 57b connected to pairs of pressure operated electric switches 67, 69, either of which pair when actuated by loss of fluid pressure set off alarms and operate solenoids shutting the machine down, and a linear variable differential transformer 63 which is directly attached to the follower piston 23 and translates the movement of rod 63a through a coil into a voltage differential operating an instrument indicating bearing wear. The follower piston 23 balanced by fluid supplied from pipe 73 to pipe 77 and inlet 29a and through a restriction 91 to pipe 81 and inlet 29b, fluid also being supplied to an internal rest chamber 39b via port 41. A micrometer 55 allows the sleeve 53 to be slidably adjusted relative to the valve 51 for calibration. In operation fluid is supplied to balance chambers 27a, 27b and valve 87 is closed so that balancing takes place through the calibrated orifice 91. In order to test the system valve 85 is opened causing only the follower piston 23 to move towards the rotor whilst the nozzle 33 remains stationary. This causes the valve 51 to cover port 57a thereby closing pressure switches 69 and operating the trip. Thereafter valve 85 is closed and valve 87 opened causing an increase in pressure in chamber 27b thereby moving piston 23 and nozzle 33 away from the rotor to move the valve 51 to cover port 57b and close pressure switches 67 so that both trip positions are tested.

Title: Process for the production of hydrazine
IPC: C01B21/16
Filed: 1953-02-02
Abstract: <PICT:0778294/III/1> Hydrazine is produced by heating ammonia to above the decomposition temperature of hydrazine and then rapidly cooling to below the decomposition temperature.  The duration of the heating should preferably be shorter than 0.01 sec., and more preferably shorter than 0.00001.  The ammonia may be directed as a high velocity stream, e.g. at a speed above 1000 ft./sec., as a liquid or gas, into contact with a flame.  The higher velocity portion of the stream is preferably brought into contact with the flame.  The flame may be produced by the combustion of hydrogen, methane, ethane, propane, butane, acetylene, or carbon monoxide. A temperature of at least 2800 DEG C. is preferably attained in the flame, e.g. by the use of stoichiometric proportions of oxygen and hydrogen.  Air or oxygen enriched air may be used to support combustion.  The gases for combustion may be preheated.  Only a portion of the ammonia may be heated to reaction temperature by the flame in which case the remaining ammonia aids in the cooling of the hydrazine produced.  Cooling may alternatively or in addition be effected by the addition to the reaction produced of liquid or gaseous ammonia or liquid water.  The ammonia may be preheated.  As shown a flat spray 15 of ammonia is directed into a flat flame 11, the spray having a greater width than the flame and the edges of the spray overlapping those of the flame.  In modifications (Figs. 2 and 3, not shown) the ammonia forms a sheath around one or more conical flames.

Title: Improvements in Polyphase Alternating Electric Current Commutator Machines.
IPC: H02K27/12
Filed: 1916-02-29
Abstract: 104,378. British Thomson - Houston Co., and Shuttleworth, N. Feb. 29, 1916. Commutating poles and windings.-Consists in providing polyphase alternating-current commutator machines with auxiliary commutating-poles 7, 8, 9 in addition to the main commutating-poles 4, 5, 6, more particularly for obtaining sparkless commutation when the directions of phase-rotation and of mechanical rotation are the same or opposed. The coils on the auxiliary poles may be open-circuited or short-circuited when phase-rotation and mechanical rotation are in the same direction; for certain speeds, they may be excited in the reverse sense. The main exciting-coils 10, 11, 12 are of less than 120 degrees pitch, being wound so as not to embrace the auxiliary poles 7, 8, 9. The auxiliary - poles are shunt or series excited, according as the main exciting-coils are shunt or series wound. Compensating-windings (not shown) are arranged on the stator. The invention is particularly applicable to commutator machines connected in cascade with induction motors for regulating their speed and powerfactor, and enables good commutation to be obtained at speeds both above and below synchronism, without its being necessary to change over the secondary connexions in passing through synchronism.

Title: Improvements in the manufacture and production of silicic acid esters
IPC: C07F7/04
Filed: 1935-01-30
Abstract: Esters of orthosilicic acid in which the silicon atom is bound to the glycerine radicle are prepared by heating the known simple orthosilicic esters with glycerides containing at least one free hydroxyl group in the glycerine radicle.  The tetra-alkyl esters derived from methyl, ethyl, propyl, butyl, or amyl alcohols, or esters derived from cyclohexanol, methylcyclohexanol, phenol or cresol may be reacted with mono- or di-glycerides of butyric, palmitic, stearic, oleic or ricinoleic acids, or glycerides containing two different acid radicles.  The temperature is preferably about 150 DEG  C.  Inert diluents, e.g. benzene or toluene, and pressures of 5--10 atmospheres may be employed. Primary, secondary or mixed esters are obtained depending on the molecular proportions of the reactants employed.  They are recovered by distilling off the alcohols formed, preferably using reduced pressure.  The esters are soluble in ether and lipins and are used in pharmacy.  Examples describe the reaction of mono- or di-butyrin, stearin, or olein with silicic acid tetraethyl or tetraphenyl ester at 150 or 140 DEG  C. under pressure.  An atmosphere of carbon dioxide is used when employing oleins.
