Patent GB-265617-A (GB)
IPC: H02J1/10
Filed: 1927-02-05
Abstract: 265,617. British Thomson-Houston Co., Ltd., (Assignees of McDonald, G. R.). Feb. 5, 1926, [Convention date]. Running generators in parallel; regulation, automatic.-Two generators 2, 3 running in parallel are regulated so that constant voltage is maintained in the common circuit 1, and so that they take equal loads, by motor operated rheostats 7, 8. Low voltage causes a relay 6 to close its contacts 9, 9<1>, completing through normally closed contacts 11, 30 a raising circuit 10R, and also energizing a relay 13 to complete through its contacts 31 and normally closed contacts 15, 32 a raising circuit 14R. High voltage causes closure of contacts 9, 17 completing through normally closed contacts 33 a lowering circuit 10L, and also energizing a relay 18 to complete through its contacts 34 and normally closed contacts 35 a lowering circuit 14L. If the generators are unequally loaded, differentially wound current coils 20, 21 on a relay 19 polarized by a winding 25 cause a contact 23 either to engage a contact 24 and complete through contacts 35 the lowering circuit 14L or to engage a contact 23<1> and complete through contacts 15, 32 the raising circuit 14R, the supply to the contact 23 being through contacts 36, 28, 29. Thus if either the circuit breakers 4, 5 are open, or the relay 13, 18 raised due to operation of the relay 6, the differential relay 19 is inoperative. Further, if either generator is overloaded, the corresponding relay 12, 16 lifts, opening the raising circuits at contacts 11 or 15 and completing corresponding lowering circuits at contacts 38 or 39. The Specification as open to inspection under Sect. 91 (3) (a) shows the coil of the relay 13 connected directly to the contact 9' instead of being connected thereto through contacts 38. This connection is not shown in the Specification as accepted.

Title: New dyestuff intermediates and process for colouration therewith
Inventor: FRANCE HAROLD
IPC: C07D209/44
Filed: 1952-02-08
Abstract: Phthalocyanine dyes are produced in situ on a textile material or other substrate by applying to the substrate a 1-imino-3-alkylmercaptoisoindolenine (see Group IV (b)) and heating in the presence of a metal compound.  A copper phthalocyanine is best obtained by heating with a copper salt in presence of magnesium.ALSO:The invention comprises 1-imino-3-alkylmercapto-isoindolenines, obtainable by alkylating an imino-thiophthalimidine.  The products can be applied to a substrate and converted to a phthalocyanine in situ, or applied to textile materials by padding or printing, and then heating if desired in presence of a metal compound.  In examples, imino-thiophthalimidine, obtained by the action of sodium sulphide in ethanol on phthalonitrile, is alkylated with dimethylsulphate in caustic soda, diethylsulphate and methyl p-toluenesulphonate, to give the corresponding 1-imino-3-alkylmercapto-isoindolemines.  Copper phthalocyanine is obtained from the products of textile material by heating in presence of magnesium and the copper salt.  The preparation of the corresponding 3-aralkyl compounds is referred to in the Provisional Specification.

Title: Means for automatically varying an electrical resistance for use in connection with the printing of kinematographic negatives
IPC: G03B27/16
Filed: 1921-01-29
Abstract: 158,829. Lobel, L. Feb. 3, 1920, [Convention date]. Printing-apparatus.-A rheostat for automatically varying the intensity of the light used in printing kinematograph films built up in sections of different densities comprises a resistance q<1>, q<2>, q<3> connected at one end to the lamp &c. r, and at the other end, as well as at intermediate points, to a number of vertical metal bars e<1> - - e<4> mounted on an insulating frame X. In front ot the bars e<1> - - e<4> and at a distance therefrom are a number of horizontal bars f<1> - - f<4> pierced with holes g, through which metal pins may be passed to connect any cf the vertical bars to the horizontal bars. The lamp r is energized by a source of current j connected to the rotary arm k of a commutator having four segments connected to the bars f<1> - - f<4>. The arm k is carried by a ratchet operated by a pawl connected to the armature e. If the sections of the film are of increasing density pins are inserted in the diagonal series of holes g<1> - - g<4>, the arm k being on the segment shown. Current then passes through all three sections q<1>, q<2>, q<3> of the resistance in the lamp circuit. As each section of the film is printed the arm k is rotated to the adjacent section of the commutator so as to cut out the sections of the resistance one by one, and increase the illumination of the lamp r in accordance with the density of the film being printed. If the current from the generator j is alternating the resistances q<1>, q<2>, q<3> may be replaced by an inductance or transformer with several connections.

Title: Improvements in cellulosic doping systems for aircraft fabrics
IPC: C09D101/08
Filed: 1945-02-15
Abstract: An aeroplane fabric dope comprises a blend of nitrocellulose, of viscosity not less than 5 seconds, and ethyl cellulose, the inherent plastic viscosity of the blend being in the range of 20.1 to 28.2 centipoises and the proportion of ethyl cellulose to nitrocellulose being within the limits of 4 : 1 and 1 : 1.5, and the dope also including a plasticiser.  Fungicides such as copper, mercury, or zinc, naphthenate, or phenyl mercury oleate, or tolyl mercury salicylate, may be incorporated in the dope.  Pigments may also be included.  The inherent plastic viscosity of the mixed cellulose derivatives is determined with a capillary tube viscometer using a 5 per cent solution of the mixture in ethyl acetate.  In an example, the dope comprises nitrocellulose (5-6 seconds viscosity), ethyl cellulose, triphenyl phosphate, butyl acetate, sec.-butyl alcohol, ethyl alcohol, toluene and xylene, and it is used for spraying on to an aircraft fabric.  Seven or eight coats are applied if the dope is sprayed cold, but only three or four coats are required if it is sprayed hot.  Over the priming coats there may be applied a single lap coat of a similar composition, but containing aluminium powder. A top coat containing pigment such as Medium Chrome Yellow may then be applied.  Other plasticisers which may be used are tricresyl phosphate, dibutyl phthalate and polyesters of sebacic acid and polyhydric alcohols chemically combined with castor oil.  Copper naphthenate or other metal soap added as a fungicide, also functions as a wetting agent and facilitates the penetration of the dope into the fabric.

Abstract: 607,537. Buffers for railway vehicles. MINER, Inc., W. H. Feb. 7, 1946, No. 3914. Convention date, June 4, 1945. [Class 103 (v)] A combined spring and friction buffer comprises a buffer head 16, Fig. 4, with tubular stem 15 slotted at 36 to receive a pin 34 fixed in the external casing A which is enlarged at 13, the base 10 being buttressed by ribs 14, Fig. 3. A friction casing 1 7 has a closed end 25, and the open end is provided with angular friction surfaces 27 to engage corresponding surfaces on blocks 19, which co-act with the surfaces of a wedge block 18. The pin 34 passes through elongated holes 36 and 126 in the plunger and friction casing respectively, the holes 36 being longer than the holes 126 to allow the plunger 15 to abut shoulders 121 on the friction casing 17 when heavy buffing occurs. On light buffing shocks the plunger 15 retracts and compresses a spring D against the closed end 25 of the friction casing whilst a heavy shock causes the end of the plunger to abut the shoulder 121 to force the wedges 19 against the wedge block 18. The casing 17 has lugs 28, Fig. 1, (not shown), and Fig. 3, engaging behind lugs 33 on the wedge block so that when the buffing pressure is released a return spring 20 frees the friction blocks 19 from the casing 17. In a modification the pin 34 passes through an elongated hole in a loose block abutting the closed end of the friction cylinder 17.
