Title: Electroluminescent luminophor and cell
Inventor: GURNEE EDWARD FRANKLIN
IPC: F21K2/08
Filed: 1962-01-04
Abstract: An electroluminescent luminophor comprises a host which is a crystalline, solid organic material capable of emitting radiation on excitation by a fluctuating electric field and, in intimate contact therewith, a particulate electron conducting material, the luminophor containing a small quantity of a guest capable of absorbing the radiation emitted by the host and of converting it into emitted light.  The colour of the emitted light is controlled by the choice of the guest, and the intensity or the yield of the emitted light or both and the efficiency of the luminophor are controlled by adjustment of the weight ratio of the guest and host.  The guest can be homogeneously mixed with the host or can be contained on or at the surface of individual crystalline particles of the host.  The host, guest and electron conducting material can be mixed intimately together. The host is a conjugated organic compound having at least one benzenoid ring and can be a conjugated organic compound which has a conjugated or condensed structure therewith, heterocyclic rings, one or more additional benzenoid rings, conjugated unsaturated aliphatic chains, or conjugated alkaryl systems. Examples of the host are naphthalene, anthracene, phenanthracene, phenanthrene, pyrene, benzpyrene, chrysene, picene, carbazole, fluorene, diphenyl, terphenyls, quaterphenyls, dihalobiphenyls, diphenylene oxide, transstilbene, 1,4-diphenylbutadiene, or binaphthyl. Many other examples are given. The guest is a conjugated organic compound having at least three condensed benzenoid rings having a different structure from the host and can be anthracene, tetracene or pentacene.  The electron conducting material can be finely divided carbon, silver, copper, copper oxide or aluminium to the amount of 0.15 to 4.5% by weight of the luminophor. The luminophor can be suspended in an inert carrier such as transformer oil or silicone oil and can be in the form of a film having a thickness of from 2.54 to 254 microns for an electroluminescent cell.  The host and guest can be mixed together, heated to the molten state, co-crystallized and then mixed with the electron conducting material.  The mixture of co-crystallized host and guest with conducting material can be heated to the molten state and allowed to crystallize by cooling. The host, guest and conducting material can be mixed together, heated to the molten state and allowed to co-crystallize.  The luminophor can be heated on a brass electrode plate above the melting point of the luminophor, pressure applied on top of the resulting fluid, and the luminophor allowed to crystallize into a thin film by cooling.

Abstract: 418,411. Doffing and tube-applying apparatus for cop-winding machines. REINERS, W., 48, Rheyderstrasse, Gladbach, Munich, Germany. Jan. 8, 1934, No. 691. Convention date, Feb. 16, 1933. [Classes 120 (ii) and 120 (iii).] In a cop-winding machine mechanism for placing cop tubes on a number of spindles simultaneously and for removing the cops simultaneously therefrom is provided with an endless conveyer carrying holders for the cop tubes extending round the machine and working in a horizontal plane. The conveyer comprises an endless chain 53<a> carrying holders 36 for cop tubes 37, Fig. 1, while the doffing and donning unit comprises bars 34<a>, 34b separately connected to racks 41<a> which are reciprocated by pinions 45. During winding, the bars 34<a>, 34<b> occupy the positions shown. The bar 34b is then moved outwardly to push the wound cops off the spindles and into the receptacle 52. The conveyer 53<a> then moves the distance required to place a fresh set of cop tubes in front of the spindles and the bar 34<a> then pushes the cop tubes 37 off the holders 36 on to the winding spindles in the course of an inward movement. In a modification, the tube holders 36 are connected to the chain links by pivots 53b, Fig. 3, and are provided with spring clips 36b for engaging the tubes. A rod 150 carried by arms 152 pivoted at 151 extends along the bank of spindles and can be swung upwards by means of a handle 152<a> so as to place the tubes 37 in alignment with the spindles. The bars 34<a>, 34<b> are fixed to one set of racks 41<a> and during inward movement the bar 34<a> pushes the tubes on to the spindles. The rod 150 is then lowered. After winding is completed, the bars 34<a>, 34b are moved outwards and the bar 34b doffs the wound cops. In a further modification, the tubes are held between stub spindles 1<a>, Figs. 4 and 5, and counter pegs 86 carried by a bar fixed to the racks 41<a>. The chain 53<a> carries pivoted holders 55 for the cops alternating with the holders 36, the gaps between holders being equal to half the pitch of the bank of spindles and the chain moving in steps equal to the gaps between consecutive holders 36, 55. When a set of cops has been wound the holders 55 are swung upwards by the handle 152<a>, the pegs are moved outwards and the holders are swung down. Then the chain moves a step and the holders are swung upwards again to bring the empty cop tubes 37 opposite the pegs 1<a>, the counter pegs 86 then being moved inwards to secure the tubes against the stub spindles 1<a>. The wound cops are deposited into a receptacle 68 by the engagement with an abutment 153 of a pin 55<b> projecting from an arm 55<a>. When winding yarn of different colours a number of receptacles 68, 68<a>, 68b with abutments 153, 153<a>, 153<b> at different levels may be provided for the different groups.

Lack of agreement brings up an alarm and stops the pump.
Patent GB-668377-A (GB)
Title: Improvements in or relating to synthetic adsorption resins
IPC: C13B20/14
Filed: 1949-01-11
Abstract: Synthetic resins having little or no ion-exchange capacity but good capacity for adsorbing complex organic molecules such as alkaloids and those producing colour, odour or taste, are made by condensing an aldehyde with an aromatic diamine, and treating the products with an oxidizing agent at a temperature above 60 DEG  C. Aliphatic amines or imines or monohydric or polyhydric phenols or derivatives thereof may also take part in the condensation.  The condensation product may also contain sulpho, carboxyl or diazo groups.  The oxidation destroys the NH2 or NH groups in the resin at least to a considerable degree.  Suitable oxidizing agents are HNO3, KNO3, KClO3 and H2O2. The resin is ground to size and preferably dried, before or after oxidation, at 80-100 DEG  C.  The resins in general immediately give off colour in alkaline medium and are regenerated after use by successive treatment with cold dilute alkali and dilute acid with subsequent washing.  In examples: (1) formalin was added to an aqueous solution of metaphenylene diamine and HCl.  The resulting resin was ground, washed, oxidized by boiling with 15 per cent H2O2, and finally dried at 85 DEG  C.  After treatment with alkali and acid it decolourized raw sugar by 98 per cent; (2) metaphenylene diamine, resorcinol and formalin were condensed in the presence of HCl and the resin product ground, washed, dried and heated with HNO3.  After violent reaction the product was washed, dried, and treated with acid and alkali.  The resin removed colour and flavour from apple pectin; (3) the resin of example (1) was tested for decolourizing action with cane sugar solution (a) before oxidation, (b) after oxidation with KNO3 under pressure at 175 DEG  C., and (c) after oxidation with HNO3; (4) a resin from meta-phenylene diamine, resorcinol and from meta-phenylene diamine, resorcinol and formalin was oxidized with HNO3 and after washing and drying caused to explode by heating to 105 DEG  C.  The resulting resin purified an inferior glucose syrup solution derived from potato starch; (5) a resin from metaphenylene diamine, resorcinol and formalin was tested for decolourizing action with sugar syrup (a) before oxidation; (b) after oxidation with KNO3, and (c) after oxidation with H2O2; (6) a condensation product from metaphenylene diamine, ethylene diamine and formalin was oxidized with HNO3 at 78 DEG  C. to give a decolourizing resin. Specification 650,706 is referred to.

Filed: 1947-01-10
Abstract: 638,864. Hinges. JONES, L. H. HOWARD-. Jan. 10, 1947, No. 852. [Class 65 (ii)] [Also in Group XI] A spring-urged hinge for the cap of the cigarette lighter described in Specification 592,657, [Group XI], is provided with a tail piece which, after the cap in its opening movement reaches a dead centre position, frictionally engages leaf spring means provided on the lighter body and initially urging the cap open ; thus the final opening movement of the cap is retarded. A hinge plate 32, Fig. 3, has a central offset tail 43, and two side parts 44 which are bent round the hinge pin 45 rotatable in a curved extension 46 of the casing 47. When a spring catch holding the cap is released, the latter is pressed open by two leaf springs 48, 49 attached to the casing 47, the tail 43 entering a slot 48A in the spring 48. The cap is frictionally braked before it is fully open, i.e. before the tail 43 engages the top of the slot 48A, since as it approaches its " dead centre position the tail engages an inclined surface 49B of the spring 49 and forces the latter away from the spring 48. The cap is held open by the engagement of the tail with a straight upper part of the spring 49. Fig. 5 shows a single leaf spring 51 pressing against the cap. Movement of the tail 43 is braked as before, but in this case the cap is held open by the tail 43 abutting a stepped part 54 of the spring 51, the part 54 also serving to limit the opening movement. The supports 46 for the hinge pin 45 are preferably formed on a plate 47A attached to the casing 47.
