Patent GB-870982-A (GB)
Title: Generator
IPC: H02K21/14
Filed: 1960-02-29
Abstract: 870,982. Dynamos. LUCIFER S.A. Feb. 29, 1960 [March 23, 1959; Aug. 24, 1959], No. 7068/60. Class 35. The head and tail lamps fed from a rotating- magnet cycle dynamo are connected to separate generating coils so arranged on different magnetic core parts that the burning out of one bulb will not affect the voltage applied to the other. As shown in the schematic diagram of Fig. 5, the head lamp 21 is energized from winding 4, while the tail lamp 22 is fed by a coil 6 on a shunt magnetic circuit 10 in series with a coil 5 on the main yoke limb 7. The turns ratios are so proportioned (tappings being provided for this purpose if desired) that on failure of the head lamp, the redistribution of flux between limbs 7 and 10 does not affect the total tail lamp voltage induced in coils 5 and 6. Similarly, on failure of the tail lamp, the cessation of current in coils 5 and 6 does not alter the flux distribution in the legs 7 and 10, so that the head lamp voltage induced in coil 4 is unchanged. In one practical construction (Fig. 7, not shown) the rotor magnet is situated between a pair of poles joined by two limbs similar to limbs 7, 10 in Fig. 5. In the form shown in Fig. 1 the generating coils are located in interdigitated-pole stator cores. The coils 4, 5 are located in the top section 7 which is built up of sectors 11, Fig. 4, having internal interdigitated poles 9 and located by a ring 12. The axial length of the rotor is equal to the height h of this stator. The coil 6 is mounted in an additional annular stator cage 10 having poles 13 which derive some leakage flux from the tips of alternate poles 9 to form the parallel flux path described. If desired both stator cage members may be made of a single punching like the cage 10. The rotor, Fig. 2, is of permanent magnet material, with or without salient poles, secured to the spindle between two discs 23, 24 having turned-down edges 25.

Title: Improvements in and relating to water closets
IPC: A47K13/10
Filed: 1940-04-20
Abstract: 540,794. Closet seats. MIKETTA, C. A. April 20, 1940, No. 7169. [Class 26] [Also in Group XXV] In a water closet having a hinged seat and cover, a water supply line and flushing valve, is provided with a member movable under the influence of the water supply and connected to the seat and cover, so as to permit the seat or cover or both to close when the pressure in the water supply line is reduced by the opening of the flushing valve. The movable member comprises a device 10 connected by a pipe 11 to the supply pipe 4 connected to a cistern 5 provided with a flushing handle 6. The device 10 comprises a housing separated by a partition 11<SP>1</SP>, Fig. 2, to form cylinders in which move plungers 12, 12<SP>3</SP> the lower ends of which are provided with cup leathers 14 held in place by screws 15. Mounted in the upper part of the device 10 are shafts 17, 18 in the form of hollow tubes, the shaft 18 being rotatably mounted in the shaft 17, and terminating at 18<SP>1</SP>, the shaft 17 extending through bearings 19, 20 formed in the upper ends of bolts 29, 22 extending through the bowl 1. The cover 3 is connected to the shaft 17 by the bracket 27 and by the bracket 27<SP>1</SP> to the shaft 18 and the seat 2 to the shaft 17 by a bracket 28<SP>1</SP> and to the shaft 18 by a bracket 28. Cams 30, 31 provided with curved faces 32, flat faces 33 and flat faces 34 are mounted in the shafts 17, 18, the latter shaft terminating within the device at about its mid-point To place the plungers 12, 13 in the operative position, a handle 36 extends through the shaft 17 being provided with a pin 37 which extends through a slot 38 in the shaft. The end of the shaft 18 is notched at 39 the pin 37 being sufficiently long to engage the edges of the notch. With the plungers 12, 13 in the position shown in Fig. 2, the handle 36 is rotated and by means of the pin 37 partially rotates the shaft 17. The cam 30 is rotated slightly into the position shown by the dotted lines in Fig. 4 and the pressure of water from the supply line 4 and the conduit 11 causes the plunger 13 to move upwardly thus raising the cover 3. If it is also desired to raise the seat 2, the handle 36 is rotated a little more, thus causing the pin 37 to engage the notch 39 and thus partly rotate the shaft 17 to operate the cam 31 and thus turn the shaft 18 to raise the seat. As soon as the flushing valve 6 is actuated, a reduction in pressure in the conduit 11, due to the flow of water to the bowl 1, as well as in the space between the plungers 12, 13 is caused, and springs 43, 44 tend to return the cams 30, 31 to their original positions. The weight of the cover and seat then rotates the shafts 17, 18, rotates the cams 30, 31 and depresses the plungers 12, 13. When the cams return to their original position, Fig. 4, the face 34 contacts the plungers and holds the seat and cover in the closed position. The pipe 11 is screwed into a part 61, Fig. 9, by means of a nut 65, the part 61 being provided with a flared opening.

Title: Improvements in or relating to the treatment of cellulosic material
IPC: D06M10/06
Filed: 1961-03-02
Abstract: Cellulosic material, particularly cellulosic textile material, is treated with a sensitizer comprising an ethylenically unsaturated compound, an aromatic compound or a primary, secondary or tertiary amine, and then subjected to ionizing radiation to effect cross-linking of the material.  The sensitizer is used in a small proportion, defined as sufficient to effect the desired cross-linking without changing the appearance or finish of the material.  Preferred sensitizers are (a) aromatic hydrocarbons having at least two uncondensed benzene rings, e.g. 1,4-diphenyl benzene, diphenylmethane, triphenylmethane, fluorene, benzal- and benzyl-fluorenes and hexaphenylethane; (b) unsaturated aliphatic aldehydes, e.g. crotonaldehyde and citral; (c) unsaturated aliphatic ketones, e.g. phorone and 2-methyl heptenone; (d) aromatic saturated and unsaturated ketones, e.g. benzophenone, chlorobenzophenone, benzalacetophenone, dicinnamylidene acetone, benzoquinone, diphenoquinone and a -naphthoquinone; (e) aromatic hydroxy ketones, e.g. p-hydroxyacetophenone; and (f) primary, secondary and tertiary aliphatic amines having 4 to 20 carbon atoms and aromatic amines having 1 to 3 benzene rings with 1 to 3 amine groups attached to the ring(s), e.g. aniline, diphenylamine, tributylamine and cyclohexylamine.  Suitable radiation includes g -, b - and X-rays at a preferred total dosage of from 5X104 to 3X106 rads.  The process may be applied to cellulosic yarns, filaments or threads, or to woven, knitted and unwoven fabrics of natural or regenerated cellulose, or to such materials containing cellulosic fibres, and which have been provided with a resin finish.  The material may be impregnated with a solution or dispersion containing less than 15%, e.g. 0,1 to 5%, by weight of the sensitizer.  Treatment with a sensitizing compound prior to irradiation obviates the need for the heating step disclosed in Specification 895,479, or irradiation in substantial absence of oxygen as in Specification 916,567.  The treated materials have improved tensile strength, and increased abrasion, crease and tear resistance.

Title: Manufacture of bis-(-a-hydroxyalkyl-)polysulphides
Filed: 1953-03-20
Abstract: A process for preparing a bis-(b -hydroxyalkyl-) polysulphide comprises (a) heating in an aqueous medium a 1,2-alkylene oxide with an alkali metal- or alkaline earth metal polysulphide in the presence of sufficient sulphur to convert the base liberated to thiosulphate and to bring about the desired degree of sulphurization; or (b) introducing a 1,2-alkylene oxide into an aqueous mixture of an alkali metal- or alkaline earth metal polysulphide and sufficient sulphur to convert the base liberated to thiosulphate and to bring about the desired degree of sulphurization; or (c) forming an aqueous mixture of sulphur and an alkali metal- or alkaline earth metalhydroxide or monosulphide and introducing a 1,2-alkylene oxide, there being initially sufficient sulphur to convert the base liberated to thiosulphate and to bring about the desired degree of sulphurization. A wetting agent may be employed to facilitate the solution of the sulphur in the aqueous medium, e.g. an alkyl or aralkyl sulphonate or other surface-active substance indifferent to the reactants.  In examples: bis-(hydroxyethyl-) polysulphide, which may be reduced, e.g. with sodium amalgam to hydroxyethyl-mercaptan, is obtained by heating a mixture of sodium sulphide, sulphur, water and dibutyl-naphthalene sulphate and, when the sulphur has dissolved with the formation of sodium polysulphide, cooling and adding ethylene oxide.

Abstract: 1364924 Estriol conjugates S J GROSS 4 June 1971 [11 June 1970 16 Nov 1970] 7823/74 Divided out of 1364921 Heading C2U [Also in Divisions C3 C4 A5 and G1] The invention comprises an antigen having a purity of at least 98% and being of formula wherein "carrier" is an immunogenic carrier (e.g. a protein, polysaccharide, polypeptide or glycoprotein); Ar is an optionally substituted arylene or divalent aromatic heterocyclic radical to which the carrier is linked through a connective group (e.g. -NH-CO-); and E is an estriol radical attached to the azo group at position 2 or 4. Specified protein carriers are bovine serum albumin, keyhole limpet hemocyanin and human gamma globulin. The antigen generally comprises a plurality (e.g. 20 or 25) of Ar-N=N-E moieties coupled to a single carrier molecule. The above antigens are prepared from estriol by reaction with diazotized HO 2 C-Ar-NH 2  to give which is chromatographed to separate the 2- and 4-azo isomers from each other and from the 1-azo by-product. The 2- or 4-isomer is then coupled to the carrier in known manner, e.g. by reaction with a carbodiimide or thionyl halide to give or (wherein R 1  and R 2  are each alkyl, cycloalkyl, aryl, alkenyl, cycloalkenyl or heterocyclic) which is then reacted with the carrier to give the desired antigen which is purified, e.g. by dialysis.  Reduction of the above HO 2 C-Ar-N = N-E intermediates, e.g. with NaBH 4 , yields a mixture of fluorescent compounds of formula and which may be separated by chromatography and extraction techniques. The above antigens may be made up with diluents into injection solutions.
