Patent GB-831802-A (GB)
Title: Improvements in methods for measuring power losses in electric power distribution networks
IPC: G01R21/02
Filed: 1956-10-25
Abstract: 831,802. Power loss measurement; current measurement. ELECTRICITE DE FRANCE. Oct. 25, 1956 [Oct. 26, 1955], No. 32606/56. Class 37. In order to determine the power losses in a power distribution network a model of the network is made and the power losses in this model are measured. Each branch of the original network is represented by a resistor R, an inductance X and two capacitors C. Where R is equal to n times the total resistance of the branch, X is equal to n times the total inductance of the branch and C is equal to 1/2n times the total capacity of the branch, where n is an arbitrary constant and the components are arranged as shown in Fig. 3. A small portion of the resistor R is shunted by a resistor p and the heating resistor r c  of a thermocouple element (Fig. 4). The value of p for each thermocouple is determined as described in the Specification to maintain correct the constants of proportionality between the power lost in any particular branch and the voltage output from the thermocouple associated with that branch. All such thermocouple elements in the model are connected in series and their combined output is indicative of the power losses in the original network (Fig. 5, not shown). This output may be compared with a standard voltage equal to the output under normal working conditions (Fig. 6, not shown), and hence differential losses in power may be determined for loads which differ from the normal load. A D.C. model using only resistances may be used if only D.C. losses are to be measured.

Title: New diazoamino compounds
IPC: C09B31/02
Filed: 1960-09-22
Abstract: The invention comprises diazoamino compounds of formula:- <FORM:0904396/IV (b)/1> wherein A is a benzene or naphthalene radical which may be substituted, B is a benzene or naphthalene nucleus which may contain alkyl, substituted alkyl, alkoxy and/or halogen atoms, A and B being free from sulphonic and carboxylic acid groups, and R1 and R2 are alkyl groups which may be substituted other than by sulphonic or carboxylic acid groups or R1 and R2 may be linked to form a heterocyclic ring.  They are used to form dyes on aromatic polyester fibres (see Group IV(c)). They are prepared by condensing a diazo compound of an amine of formula OHC-A-N=N-B-NH2 with a secondary amine of formula <FORM:0904396/IV (b)/2> In examples: (1) the zinc chloride complex of the diazo compound of 4-amino-2:5-dimethoxy-41-aldehydo - azobenzene is condensed with dimethylamine acetate in aqueous medium; (2) as in (1) but the diazo compound of 4 - amino-2-methyl-5-methoxy-41-aldehydoazobenzene condensed with morpholine acetate.  Further examples are specified.ALSO:Aromatic polyesters are dyed or printed by applying thereto from an aqueous medium a coupling component free from sulphonic acid groups and a diazoamino compound of formula <FORM:0904396/IV (b)/1> wherein A is a benzene or naphthalene radical which may be substituted, B is a benzene or naphthalene nucleus which may contain alkyl, substituted alkyl, alkoxy and/or halogen atoms, A and B being free from sulphonic and carboxylic acid groups and R1 and R2 are alkyl groups which may be substituted other than by sulphonic or carboxylic acid groups or R1 and R2 may be linked to form a heterocyclic ring (see Group IV(b)) and the dyeing developed, preferably by heating in the presence of an organic acid. Dark brown, dark blue, navy blue and black shades are obtained.  In an example polyethylene terephthalate fabric is introduced into an aqueous bath containing the diazoamine compound from diazotised 4-amino-2:5-dimethoxy-41- aldehydo-azobenzene and dimethylamine, 2-(21:31- hydroxynaphthoylamino)-naphthalene, a condensation product of cetyl alcohol and ethylene oxide, disodium phosphate, sodium phosphate and odichlorobenzene.  The bath is heated to 100 DEG C. and the goods treated for 60-90 minutes then developed in a further bath containing salicyclic acid at 120 DEG C.  A black dyeing is obtained. The fastness to rubbing of the dyed material may be improved by treating in an aqueous bath containing sodium hydroxide, sodium hydrosulphite and a non-ionic wetting agent.  Further examples are specified.  4-Amino-41-aldehydo-azobenzenes are prepared by diazotising 4-aminobenzaldehyde or 4-amino-3-chlorobenzaldehyde and coupling with 2:5-dimethoxy-aniline, 2-methoxy-5-aniline or m-toluidine or

Breech mechanism for a gun employing primer cartridges comprises a transverselysliding breech-block 1, a slider 5 mounted in the breech housing 6 for movement in contact with the rear face of the breech-block 1 and along the line of movement thereof, a firing mechanism located in the slider 5 and stops 8, 9 on the housing 6 for limiting the movement of the slider together with projections 22a, 7 on the breech block adapted to engage the slider 5 so that in its extreme positions against the stops 8, 9 the breech-block reaches its open and closed positions. A cylindrical primer cartridge magazine 2 is detachably mounted for rotation in a recess 12 in the rear face of the breech block and is so arranged that when the breech block is closed rotation of the magazine brings successive primer cartridges past a vent which extends through the breech block coaxially with the barrel, the magazine 2 being rotated by a lever 4 each time the breech block is operated, an ejector 3 for the spent cartridges operated when the breech is opened and a ridge 22 on the slider 5 for pressing each cartridge home in the vent as the breech-block moves to its closed position. When the breech is opened, the breech-block 1 and slider 5 initially move as far as the stop 8 and move together by virtue of an arresting pin 25 but after reaching the stop 8, the breechblock continues to move to disengage the arresting pin and the ridge 22 on the slider 25 clears a groove in the magazine 2 to permit it to rotate when the lever 4 mounted in a recess in the breech-block 1 engages a stop in the housing 6. At the end of the opening movement the ejector 3 is pivoted to eject the spent cartridge case and the arresting pin 25 engages again. During the closing operation the slider 5 is carried along by the breech-block by virtue of the pin 25 until the slider reaches the stop 9 when the pin 25 is disengaged and the breech block continues to move upwardly until the lug 7 engages the slider. The ridge 22 enters a recess in the end face of the magazine to push the cartridge into the firing position, with the slider and firing mechanism positioned behind the cartridge and held by lug 7.
