Patent GB-288159-A (GB)
Abstract: 288,159. I. G. Farbenindustrie Akt.- Ges. March 31, 1927, [Convention date]. Benzodiazines are prepared by condensing a homologue, derivative or substitution product of a 2: 4-dihalogen-quinazoline with two similar or dissimilar molecules of a compound which contains a reactive hydrogen atom attached to a nitrogen, oxygen or sulphur atom. The products are useful as intermediates for the manufacture of dyestuffs and pharmaceutical compounds. According to the examples, (1) 6-nitro-2 : 4-dichloroquinazoline (1 mol.) is condensed with 2- amino-5-hydroxynaphthalene-7-sulphonic acid (2 mols.); the product does not react with nitrous acid, but couples with 2 mols. of diazo-compounds; it is reduced to an amino-compound which also couples with diazo-compounds (2 mols.); as quinazoline starting material, 7- methyl-2 : 4-dichloroquinazoline, 2 : 4-dichloro-linnaphtho-1 : 3-diazine, 6: 8-dinitro-2 : 4-dichloroquinazoline, or 2 : 4 : 7-trichloroquinazoline may be employed; (2) the products of the preceding example may be further condensed with a quinazoline, e.g. 6-nitro-2 : 4-dichloroquinazoline (1 mol.) is condensed with 2-amino-5-hydroxynaphthalene-7-sulphonic acid (2 mols.) and the produce reduced and the amino-compound again condensed first with 2: 4-dichloroquinazoline (1 mol.) and then with 2-amino-5-hydroxynaphthalene-7-sulphonic acid, yielding a compound which reacts with diazo-compounds (3 mols.); (3) 6- nitro-2 : 4-diohloroquinazoline (1 mol.) is condensed with 1-amino-8-hydroxynaphthalene-3 : 6- disulphonic acid (1 mol.) and with aniline (1 mol.); the product gives by reduction an amino body which couples with diazotized sulphanilic acid and can itself be diazotized and coupled with 2-naphthol-3 : 6-disulphonic acid. The use of amino-anthraquinones in these condensations is mentioned. Quinazoline derivatives are prepared by treating the corresponding 2 : 4-dioxyquinazoline with phosphorus pentachloride in phosphorous oxychloride. 2: 4-Dioxynaphtho-1 : 3-diazine is made by melting 2-naphthylamine-3-carboxylic acid with an excess of urea and 7-chloro-2: 4-dioxyquinazoline from 4-chloro-2-aminobenzoic acid and urea.. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of 2: 4-dichloro-copazoline and 2 : 4-dichloro-(quinoline- 1 : 3-diazine). This subject-matter does not appear in the Specification as accepted.

In a fishing reel of the kind wherein the line is wound on to a reciprocating spool 33 by a pick-up 32 mounted on a rotatable casing 30, the driving gear comprises a crown-wheel 2, Fig. 2, having a cam track 40 adapted to drive an axially reciprocable shaft 6, the shaft 4 of the crown-wheel passing through the housing 8 of the reel and the reciprocable shaft 6 terminating short of the crown-wheel shaft 4. A winding handle is detachably secured by a screw to either end of the crown-wheel shaft 4. The reciprocable shaft 6 is slidably mounted in a housing 38 and has a pin 34 which projects through a slot 36 in the housing 38 to engage the cam track 40 in the crown-wheel 2. The pick-up casing 30 is rotatable on the reciprocable shaft 6 and has a bevel gear 28 meshing with the crown-wheel 2. The spool 33 is held on the reciprocable shaft 6 by a threaded member 50. A floating spring-loaded pawl 58, Fig. 3, mounted on the underface of the spool engages a ratchet wheel 46 keyed to the reciprocating-shaft 6 and is pivoted to a plunger 60 which projects through a peripheral flange on the spool and has a slot adapted to receive the loose end of the line so that the line is gripped against the peripheral spool flange. The line is released by rotating the spool slightly in the direction to cause the pawl to lock with the ratchet wheel 46 and move. the plunger proud of the peripheral flange. The wire pick-up 32 has two turned-in ends 52, 54, which pass through holes in the pick-up casing 30, one end 52 serving merely as a pivot, the other end 54 extending inwardly and being deformed by a projection 56 on the casing to spring load the pick-up. The pick-up is restricted to 90 degrees rotation and one extreme position, used for casting, is just past the dead-centre position of the spring loading. On rotation of the pick-up casing 30 the pick-up strikes a stop on the reel bracket and automatically returns to the linewinding position. A spring-urged pawl 10, Fig. 2, pivoted on the inner face of the reel housing 8 engages the teeth of the crown-wheel 2 to allow the wheel to be rotated in the winding- in direction only and a pivoted lever 16, Fig. 1, has a recessed portion 20 which engages a pin 22 on the pawl 10, whereby manual rotation of the lever moves the pawl out of engagement with the crown-wheel.

A switch comprises at least one group of contacts mounted on parallel wires and operable by a slide movable in a rectilinear path parallel to the axes of the wires, the slide having a pre. determined pattern of cam depressions on its surface. As shown, the operating member is a handle 19 pivoted at 21 and has an extension 18 with ears 25, 26. The lower surface of extension 18 has a central depression 29 and two semi-circular recesses 27, 28 which co-operate with a roller 43 to locate and retain the handle in its central and two end positions, respectively. The roller is carried by a lever 35 pivoted at 34 and urged upwards by a spring 31. When the handle is tilted, e.g. clockwise, the ear 25 engages a lug 84 on a link secured to slides 50, 51 which are secured together by a rivet 80, the slides thereby being moved vertically upwards. Movement of the handle in the other direction causes similar upward movement of slides 52, 53. The slides are urged down by springs 90, 91 and each slide is formed with a depression 160 having irregular boundaries 54, 58 co-operating with elements, such as 61e, secured to wire springs 61a, the elements 61e also serving as contacts which co-operate with pairs of contacts 62g on wire springs 61b, 61c. The contacts are open when the elements 61e engage the depressions, and closed when they engage the normal surface of the slides, as shown at the left and right respectively of Fig. 8. The depressions may be arranged so as to cause simultaneous or successive operation of the contacts. The handle may be retained in one end position only, or the locating mechanism may be completely omitted so that the handle is retractive from both end positions. The wires 61a &c. are moulded in insulating blocks 100, 101 secured to the base by screws 106, and U-shaped covers 120, 121 are secured by notches 124, 125 which clip over ridges 122, 123 on the base.

Patent GB-301797-A (GB)
Abstract: 301,797. Fast, F. Dec. 5, 1927, [Convention date]. Coins, separating and sorting.-A coin-sorting device comprises discs 4 - - 7 mounted on a vertical rotatable shaft 2. An annular space is provided between the edges of the sorting discs and the casing 1. The discs are downwardly inclined from the shaft 2, and progressively increase in diameter, the top disc 4 being the smallest. The coins are poured in through a funnel 8, and are thrown by the rotation of the discs against the wall 9<a> of the casing 1 which prevents coins passing direct to the channel 11. The coins then move along the wall 9b, all but the largest dropping through the annular space to the next disc. The largest coins pass through the channel 11 to a container 15. The process is repeated at each disc, the sorted coins passing to containers 16, 17, 18. To remove coins from the containers a key 31, Fig. 3, is depressed to move a plate 24 into the container. Projections on the plate 24 press against the upper edge of a hinged half-cylinder 21 so that it swings outwardly with the pile of coins which may then be removed. Coins above the pile are prevented from falling by the plate 24. The wall 21 and plate 24 are returned to the original positions so that the coins held up by the plate 24 drop to the bottom of the container.
