Title: Improved means for feeding the links in chain-making machines
IPC: B21L9/00
Filed: 1935-12-10
Abstract: 463,089. Feeding chain links from hoppers. HARCOURT, B. W., and MANN, A. J. Dec. 10, 1935, No. 34171. [Class 78 (i)] Flat plate links used in making chains are delivered centrifugally from a loose mass in a hopper into a tangential delivery passage leading to a shoot, and are forwarded along the passage and shoot respectively by two sets of co-ordinated pushing-mechanism. Means are also provided for removing any links passing along the delivery channel in other than a predetermined position. The rotating table b forming the bottom of the hopper a throws the links centrifugally into a channel g formed under the projecting ledge d. This channel communicates tangentially with a delivery channel h along which the links are pushed by a reciprocating arm j. Pegs o on a rotating disc swing the lever k about the pivot m and thus move the arm j to feed the links. A spring q returns the arm. The delivery channel is formed with a curved recess 6 in the wall directly opposite to a spring- mounted pusher 7. When dealing with curved links of the shape shown, should a link reach the pusher with its concave edge adjacent thereto, the latter moves forward and pushes the convex edge into the recess 6, and the action of the arm then causes this plate to be swung round into the shoot 9 for subsequent return to the hopper. The remaining plates pass to a delivery shoot 5 in which they form a stack and are pushed downwards by the intermittently-operated plate. t driven from the lever k through the rod s so as to perform its working stroke during the idle stroke of the arm j.

The invention comprises also azo-pigment dyes containing in the molecule at least one of the groups <FORM:1083315/C4-C5/3> or <FORM:1083315/C4-C5/4> in which A, R1 and R2 are as defined above. The pigment dyes are prepared by reacting non-azo dyes of the general formula <FORM:1083315/C4-C5/5> or azo dyes which contain at least one group of the formula <FORM:1083315/C4-C5/6> with ammonia, a primary mono-amine or a primary di-amine.  The residue Z may be derived from dyes of the anthraquinone phthalocyanine, indigo and thio indigo series and the hemiquinoid dye groups for example mono amino anthraquinone and diamino anthraquinone. The azo pigments may be mono- or dis-azo products with the cyclic imido group in the diazo or coupling constituent of the dye molecule.  In examples: (1) 4-amino naphthalic acid anhydride is diazotized and coupled with 2 - (21,31 - hydroxy naphthoyl amino) toluene or with 4,41-di-(aceto acetyl amino)-3,31-di-methyl-diphenyl and the resulting azo dyes are reacted with aniline to convert the anhydro groups present to the imido groups; (3) 3-(p-amino benzoylamino)-naphthalic acid anhydride is diazotized and coupled with the first mentioned coupler of (1) and the monoazo dye is then reacted with 3,5-dimethylaniline; (4) copper phthalocyanine tetra sulphochloride is reacted with 3-amino naphthalic acid anhydride and the corresponding imido compound is formed by reacting the product with NH3.ALSO:3-(p-Aminobenzoylamino) naphthalic acid anhydride is prepared by reacting p - nitrobenzoylchloride with 3-amino-naphthalic acid anhydride and reducing the resulting 3-(p-nitrobenzoylamino) naphthalic acid anhydride (Example 3).

Title: A new or improved electro-magnetic key clutch or ratchet clutch
IPC: F16D43/00
Filed: 1927-12-24
Abstract: 299,230. Bain, R., and Fenton, J. Dec. 24, 1927. Clutches, positive and ratchet.-A clutch ior driving a shaft from a disc or wheel loose thereon comprises a radially-movable electromagnetic key adapted, on momentary energization of the electromagnet coil, to be attracted by the shaft and engage a ratchet tooth thereon, and to be disengaged by overrunning the shaft. The driven shaft 10, Fig. 1, has one or more spiral grooves 11 or spiral projections forming a ratchet tooth or teeth 13, and carries loosely a gunmetal or other non-magnetic disc 14, which supports a toothed steel ring 21 and has a covered recess 15 for the magnet coil 18 and the clutch-key 12 forming the slidable core thereof. On closing the coil circuit through slip rings (not shown) and contacts 30, 31 on the ring 21 and disc 14 respectively, the key 12 normally retracted by centrifugal force aided by a spring 17, is attracted to the shaft as soon as the tooth 13 passes under it, and finally abuts against the tooth face. The ring 21 and disc 14, being connected by a lug 20 and yielding spring 22, are then relatively displaced to carry the contact 30 over an insulating segment 42 and to bring lugs 29 over the end of the key 12. The centrifugal force on the key 12 is largely balanced by the pressure thereon of the end 32 of a weighted lever 24, which is pivoted at 25 and lies in a recess 23, 27 in the disc and in a groove 28 in the ring. Excessive pressure of the lever 24 on the key in the engaged position is relieved by its contacting with the stem 36 of an auxiliary spring-pressed centrifugal mass 35. When the driving-ring 21 is retarded, as by the throttling of the engine when the clutch is used in constantmesh with variable-speed gearing, the lugs 29 move back to free the key. which is thrown out by centrifugal force, the spring 17, and, the overrunning of the shaft 10. Fig. 5 shows a modification, in which the disc is replaced by a housing 14a supported by arcuate lugs 38 sliding in slots 39 in side plates 40 bolted to the toothed ring 21, which carries the lever 24, the compensating- mechanism 35 &c. not being shown. The Provisional Specification describes a magneticallyactuated pivoted detent for latching the key in its outer position, and states that the shaft may be the driving or driven member.

Title: Improvements in or relating to liquid level indicating arrangements of the transparent gauge type

Abstract: 392,642. Indicating liquid levels. ELECTRICAL IMPROVEMENTS, Ltd., Carliol House, Newcastle-on-Tyne, and BLACKBURN, C. L., 2, Ryder Street, London. Dec. 18, 1931, No. 35097. [Class 123 (i).] In a liquid-level indicator of the transparent gauge type, wherein an indication of the level is obtained at a distant point by transmitted light owing to the difference between the refractive indices of the liquid and the gas or vapour above it, the gauge comprises two sheets of mica or other corrosion-resisting material inclined at an angle, and separated by a wedge-shaped space containing the liquid. A flat beam of light is directed on to one of the sheets at such an angle that after refraction through the central space, it will emerge as two divergent beams above and below the liquid level respectively, so that only one will be visible at a chosen observation point. Alternatively, differently coloured beams may be employed for the upper and lower emergent beams. Two prisms A<1>, A<2> of glass are mounted vertically in a support B having openings B<1>, B<2> for the passage of light. The central space D between the prisms is connected at its upper and lower end to the steam and water space respectively of the boiler, and mica sheets E<1>, E<2> are provided on the inner surfaces of the prisms, bolts C<3> forcing the prisms against internal shoulders B3. In a modification, Fig. 5, the mica sheets E<3>, E<4> are separated from parallelsided plates A<7>, A<8> by wedge-shaped distance pieces F, the small pockets F<1>, F<2> being filled with liquid. The indications of the gauge may be reproduced at a convenient position on the firing floor by the optical arrangement described in Specification 387,752. Two colour indication may be arranged as described in Specification 392,882, by providing two colour screens M, M<1> respectively a red and green between a condensing mirror H<2> and the gauge G. A small prism M<2> deflects the red rays on to the gauge, the light being provided by any source H<1> and a spherical reflector H<3>. The prism is chosen so that the upper red emergent beam lies in the same plane as the lower beam. Figs. 9 and 10 show the path of the rays below and above the water level respectively, the red rays being indicated by dotted lines, thus the gauge is represented by a red upper part and green lower part the water level being shown by the dividing line between them. Specification 263,638, [Class 123 (i), Liquid-level regulating &c.], also is referred to.
