Title: Hopper feeder for equalising the quantities of textile fibre issuing from an openeror the like
IPC: D01G23/00
Filed: 1954-12-01
Abstract: 756,418. Feeding fibres. TEXTHOLD, AKT.-GES. Dec. 1, 1954 [Dec. 4, 1953], No. 34850/54. Class 120 (1). [Also in Group XXX] A hopper feeder for textile fibre material has a shaft tapering towards a roller pair 9, 10 disposed at the shaft exit, the shaft walls being formed by separately driven rollers or endless aprons or the like; the frictional forces between the roller or apron drive and the fibre material are so controlled that fibre is supplied to the space before rollers 9, 10 only until the material has been compressed to a predetermined extent, whereafter, due to back pressure exerted by the material in the said space, slip occurs between the material and the roller or apron drive. As shown, fibre is fed into a wedge-shaped hopper the sides of which are formed of driven rollers 1-8 which convey the fibre to driven delivery rollers 9, 10. When a predetermined fibre density is reached in zone A, rollers 1-8 slip over the fibre. Rollers 1-8 may be replaced wholly or in part by endless aprons. The roller or belt surfaces may be rough or provided with needles so as to exert a positive grip on the fibre ; in this case, a friction clutch inserted between the outer shell of each roller and its driven core provides the necessary slip; where needles are used, they are inclined so as to be readily extracted from the fibre. In each hopper construction, smooth side walls are provided perpendicular to the direction of the roller axes.

Title: Handling ferromagnetic loads
IPC: B66C1/04
Filed: 1973-07-23
Abstract: 1390582 Magnetic lifting devices INSTITUT MANIPULACNICH DOPRAVNICH OBALOVYCH A SKLADOVACICH SYSTEMU 23 July 1973 [24 July 1972] 34921/73 Heading B8H [Also in Division H1] A magnetic hoist comprises a member 1 having envelope 2 and magnetic core 3 resting on ledges 4 of the latter, which carries a suspension device 5 having a guide slot 6 therein. Guides 7 engaging pressure pads 8 are also carried by envelope 2, and to the pads are pivoted levers 9 connected to the envelope by rods 10. The levers also carry suspension points 11 for suspension members 12 and terminal suspension points 13 for suspension members 14. A pin 15 moves in guide slot 6 with piston-rod 16, whose upper end carries a suspension head 17 and a piston 18 with a throttle bore 19 and valve 20 moving within oil filled cylinder 21, whose upper end member 22 carries suspension members 12. A further support 23 above the cylinder is movable along rod 16 and has claws 24 engaging latches 25 on frame 26 under control of a control mechanism; the frame having elongate aperture 27 in which suspension head 17 is vertically movable. A ferromagnetic load 28 is engaged by the magnetic core 3, and on lifting frame 26 rod 16 is raised and pin 15 slides in slot 6. Piston 18 rises and compresses the oil in cylinder 21 to raise the latter; thus tensioning suspension members 12 to pivot levers 9 and depress pads 8. This adds to the natural weight of the load; which is raised if the total load is less than the magnet capacity and is left stationary if it exceeds the magnet capacity. During raising (Fig. 2, not shown) piston valve 20 closes and the pressure oil enters the lower part of the cylinder through piston bore 19. Thus piston-rod 16 raises relatively to the magnet until pin 15 abuts the upper end of slot 6, when movement of the piston ceases and the force exerted by suspension members 12 and pads 8 also ceases (Fig. 3, not shown). The magnet then overcomes the true weight of load 28, which is raised. During lowering (Fig. 4, not shown) piston 18 is depressed into cylinder 21 by pressure of support frame 26 on head 17, and valve 20 opens. Subsequently (Fig. 5, not shown) support member 23 is engaged with support frame 26 by claws 24 and latches 25 under central control and on raising the frame syspension 14 is tensioned to pivot levers 9 and apply pressure on the load through pads 8, whereby the magnet is separated from the load. On application to a further load 24 (Fig. 6, not shown) the initial lifting condition is re-established. The hydraulic dashpot piston and cylinder may alternatively be pneumatic, or an equivalent mechanical linkage. The hoist is suspensible directly from a crane hook, or in plurality from a beam suspensible from the hook (Figs. 7 to 10, not shown).

Title: The manufacture of new alkylated 5:5 phenylethylhydantoins
IPC: C07D233/72
Filed: 1933-12-15
Abstract: N-alkylated 5-5phenyl ethyl hydantoins are prepared by treating 5-5 phenyl ethyl-hydantoin or its N-monoalkyl derivatives with methylating agents or by treating phenylethylmethylureidoacetonitriles with acids and then alkylating the product.  The products are of the formula <FORM:0430255/IV/1> wherein at least one R is methyl and the other may be hydrogen or a saturated or unsaturated alkyl group.  The first alkyl group enters in the N3 position.  In examples: (1) the 3-methyl derivative is made by heating phenylethyl hydantoin in dilute soda with dimethylsulphate; (2) the 1,3 dimethyl derivative is made by treating the product of example 1 in alcohol with soda and dimethyl sulphate or by using twice the quantity of dimethyl sulphate in example 1; (3) phenylethylmethylureidoacetonitrile is heated with hydrochloric acid, yielding 1 - methyl - 5 - 5 phenylethyl hydantoin; (4) the product of example 3 is heated with aqueous soda and dimethyl sulphate. Phenylethylmethylureidoacetonitrile is obtained by condensing phenylethyl ketone with hydrocyanic acid and methylamine yielding phenylethylmethylaminoacetonitrile, which is then condensed with cyanic acid.  The Specification as open to inspection under Sect. 91 contains examples in which (6) 5,5-phenylethylhydantoin is treated with ethanol and soda; (7) to (10) 5,5-phenylethyl hydantoin dissolved in ethanol is condensed in presence of soda with allyl, propyl, butyl, isobutyl and isoamylbromides and with benzyl chloride respectively; and (12) phenylethylbenzylureido acetonitrile or the corresponding chlorbenzyl, nitrobenzyl, allyl or alkyl derivatives dissolved in ethanol are treated with hydrochloric acid.  Similar products to those described above may be made by alkylating 5-phenylhydantoin and then ethylating the product.  Mention is also made of alkylation or aralkylation of the hydantoin with alkyl or aralkyl halides and with the propyl ester of p-toluene sulphonic acid.  The subject-matter of Specifications 430,282 and 430,283 is also included.  This subject-matter does not appear in the Specification as accepted.
