Title: Ground current powered ground fault protector
IPC: H02H3/347
Filed: 1973-01-24
Abstract: 1400946 Protective arrangements SQUARE D CO 24 Jan 1973 [7 Feb 1972] 3565/73 Heading H2K An earth fault protective arrangement comprises means, e.g. a differential transformer 15, for detecting unbalanced current in the conductors 11a, 11b, 11c, 12 supplying a load (not shown), operating means energized solely by the detecting means for operating disconnecting means (not shown) in response to a predetermined magnitude of unbalanced current, and time delay means delaying the energization of the operating means for a time interval after the unbalanced current reaches the predetermined magnitude. As shown, when the unbalanced current is sufficient, a triac 99 is rendered conductive to complete a low impedance circuit for the energization of the primary winding 22p of an auxiliary transformer 22 from the differential transformer 15. The output of the secondary winding 22s is rectified by a bridge rectifier 25 having voltage regulating transistors 26, 27 with Zener diodes 29, 30. When the output voltage of this rectifier is sufficient, a transistor 39 is rendered conductive so that capacitors 47, 54 in two timing circuits are charged by this output voltage. When either capacitor is sufficiently charged, a threshold device 77 conducts to turn on a triac 79. This completes a circuit through the bridge rectifier 40 for the trip coil 87 of a circuit-breaker and switches off the triac 99 so that the full output of the transformer 15 is applied to the coil 87. In the event of a high earth fault current, the voltage across a voltage divider 66, 67 is sufficient to cause the triac 79 to conduct without delay. Should certain of the components fail then a fuse 95 will blow, open circuiting the triac 99 and enable the triac 79 to cause the energizing of the coil 87 without delay in the event of an earth fault.

Title: Improvements in or relating to apparatus for deflecting the head lamps of vehicles
IPC: B60Q1/124
Filed: 1929-02-02
Abstract: 305,241. Dietrich, F. R. Feb. 3, 1928, [Convention date]. Vehicle lamps, directing.-In an arrangement in which vehicle headlights are deflected by the steering-gear, a coupling is interposed between the steering-gear and the lamps so that when changing to and from steering straight ahead, the lamps are brought with a lead to their normal and greatest deflected positions earlier than the steering wheels. In one form, the steering column lever 6 is connected by means of a rod 10 to a lever 11 which is mounted on an axle 12 carried in a housing 13. A disc 14 is non-rotatably mounted on the axle 12 but is capable of axial displacement and is pressed by a spring 18 against a cord disc 15. The disc 14 carries a controlling part 19, the disc 15 carries projections 20, 21, and the housing 13 carries stops 22, 23 and flat spring catches 24, 25. A Bowden-wire 26 is carried round the disc 15 and is led through necks 27, 28, flexible tubes 30, 31, and a neck piece 32, on to a smaller cord disc 37 on the axis 35 of the lamp 36. When the steering gear is operated in one direction the controlling-part 19 raises the catch 25 out of the way of the projection 21 and the disc 15 rotates with the disc 14 to deflect the lamp 36. When the projection 20 reaches the stop 23 the disc 15 is held fast and the lamp is not further deflected by further deflection of the steering wheels. When the steering gear is reversed the disc 15 rotates with the disc 14 and the lamp reaches its normal position before the steering wheels, being held fast by the projection 21 engaging the catch 24, whilst the steering wheels are further deflected to bring them back to their normal position.

Title: Quaternary ammonium compounds and treatment of textile materials therewith
IPC: D06M13/402
Filed: 1945-02-14
Abstract: Organic nitrogen compounds, capable of being converted into quaternary ammonium compounds, are prepared by heating fatty acid amides or equivalent mixtures of fatty acids and fatty acid amides or of fatty acids and fatty acid nitriles, said fatty compounds containing 12 to 30 carbon atoms, at temperatures above 300 DEG  C. and preferably between 300 DEG  and 350 DEG  C. until the acid number of the product is reduced to below 25.  The reaction between fatty acid and fatty acid amide is preferably effected in the presence of a dehydrating catalyst such as zinc chloride.  The products, believed to be novel di-acyl-imides, may be reacted with formaldehyde and hydrogen chloride and the chormethylated product reacted with a tertiary nitrogen base such as pyridine, quinoline and the picolines. The resulting quaternary salts may be used in the treatment of fibrous materials (see Group VIII).  In examples: (1) commercial stearamide containing 5 per cent free fatty acid is heated to 320 DEG C. for 17 1/2 hours in a nitrogen atmosphere whereby the acid number is reduced to 15.2; the resulting di-stearimide is distilled and reacted with paraformaldehyde and hydrogen chloride and then with pyridine; (2) a mixture of stearic acid and stearonitrile is heated for 24 hours at 325 DEG  C., 1 per cent stearamide is then added as catalyst and heating continued for 12 hours when the acid number is reduced to 22.5; the product is worked up as in (1); (3) lauric acid amide is used in place of stearic acid amide in the reaction described in (1); (4) stearic acid and stearamide are heated at 330-340 DEG  C. for 36 hours when the acid number is reduced to 14.2 and the resulting product is treated as in (1) to yield a similar quaternary compound.  Other amides specified include those of myristic acid, palmitic acid, montanic acid and the acids obtained by the catalytic oxidation of aliphatic hydrocarbons.

Title: Improvements in or relating to apparatus for the measuring and indication of viscosity of liquids
IPC: G01N11/08
Filed: 1935-02-06
Abstract: 442,974. Viscosimeters. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.- (Sterling Engine Co. ; 1252, Niagara Street, Buffalo, New York, U.S.A.) Feb. 6, 1935, No. 3838. [Class 106 (ii)] Comprises a constant pressure chamber receiving a limited quantity of liquid from a supply at a higher pressure, a relief valve for producing the constant pressure, thermostatic means in direct contact with the liquid acting on the relief valve, and viscosity measuring means to which liquid is discharged from the chamber. The device 10 may be introduced into a line of piping A through which liquid is flowing and is provided with flanges b for bolting to flanges a on the pipes. The liquid flows from the pipe through an opening and a filter into a channel 18 and through a fine orifice 19 to the chamber 20. The fine orifice is formed in a screw plug. The liquid passes from the chamber 20 by means of another fine orifice in a plug 51, and a capillary tube 52. Another passage 26 is provided with a valve 25 and leads to a passage 27 vented to the atmosphere by a hole 29. This passage 27 leads to a sump not shown. The spindle 34 of valve 25 is connected by a link 42 with an arm 41 connected to the thermostatic device. This comprises a thermostatic spring tending to close the valve and serves to regulate the opening of the valve 25 and thus keep constant the pressure in the chamber 20. It consists of two bimetallic strips 35 connected at one end 36 to the wall of the chamber 20 and at the other end to a shaft 38. Between the coils, the shaft is connected to an arm 39 which forms part of the adjustable arm 41. The effective length of the arm may be altered by slacking the screw 44 and turning the screw 47 which engages a worm quadrant on the end of the arm 39. The screw 44 is then tightened. Liquid enters through the plug 19 and splashes against the cover and over the coils to keep them at the temperature of the entering liquid. A pressure gauge 55 is connected by a duct 54 with the tube 50 near the plug 51 and may be calibrated to read viscosity. A screwed rod 60 operated by a hand wheel 62 may be moved so that the end blocks the passage from the piping and cuts the device off from the conduit A.
