Title: A method of drawing formed material from a plurality of sources
IPC: B21D43/18
Filed: 1966-10-21
Abstract: 1,105,900. Metal sheet feeds. SVENSKA. ROTOR MASKINER AKTIEBOLAG. 21 Oct., 1966 [23. Oct., 1965], No. 47157/66. Headings B3A and B3W. A method of simultaneously drawing strip material from a plurality of sources and advancing it in unison comprises the steps of supplying said material from a plurality of sources to feed rollers having a magnetic field sufficient to hold the strip tightly thereto and rotating the rollers to draw the strip material from the sources and advance it to a point of use. A metal strip 16 from a roll 12 passes through a corrugating or notching press 22, over a hump table 30 and to continuously rotating magnetized feed rollers 28. A second strip 17 from a roll 13 passes over a guide roller to the hump table and then to the feed rollers 28. A third strip 18 from a roll 14 passes through a corrugating or notching press 24, over a guide roller to the hump table 30 and then to the feed rollers 28. The three strips form a sandwich which is advanced through a shear 32 to an electrically or mechanically operating flag switch and gauging stop 38 which triggers the shear to cut the sandwich into lengths suitable for use in a regenerative heat exchanger. The presses 22, 24 operate at a speed such that the strips pass through them at a slightly slower speed than that provided by the feed rolls 28. When the shear 32 operates the sandwich is momentarily halted and slips on the feed rollers which contain either permanent or electromagnets. The rolls 12, 13, 14 are freely rotatable on their supports.

Abstract: 1322580 Coin freed vending apparatus A BURLANDO and S BOSCO 5 Oct 1970 [15 Oct 1969 17 Sept 1970] 47276/70 Heading G4V A vending machine has a number of horizontal vending units arranged both vertically and depthwise horizontally with respect to each other. Each unit is provided with an individual dispensing and change giving device and is independently removable from the machine. The machine preferably has a common set of coin slots of coin checking devices (not shown) and a common withdrawal door 42 for both the articles and the change. Operation.-In the embodiment shown packets 15 are supported by a pair of angle irons 8 which carry rollers 12 that run on rails 12<SP>1</SP> fixed to the frame of the machine. Situated between, and slidably mounted on the angle irons 8 is a rack mechanism 1, further linked to the angle irons by springs 131 (see also Figs. 3 to 8, not reproduced). The rack mechanism carries a slidably mounted box 17, which has a pivoted pawl 20, the box bearing against the packets and moving one position towards the delivery position on each reciprocation of the rack. Fixed to the rack is an arm 6 which carries spring loaded pivoted flaps 22 and 26 which ensure that only one packet is dispensed in each operation (see also Figs. 9 to 13, not reproduced). One electric motor 30 is provided for operating all the vending units, the motor reciprocating a particular rack through shaft 33 and an arm 34 which is pivoted up into contact with wheel 5 by a solenoid 35 controlled by the respective selection button 31<SP>1</SP> situated alongside an article display window 32<SP>1</SP> (see also Fig. 14, not reproduced). A cam 7 mounted on the rack pivots arm 37 to move an apertured plate 38 beneath change tubes 36, the amount of change given being controlled by the number of tubes 36 filled. In another embodiment (Figs. 16 to 20, not shown) the rack is provided with a slidable rod (43) that carries at one end the wheel 5 and at the other end a transverse rod (44). The rod (44) acts on a further slidable rod (46) which carries a packet retaining plate (50). On operation of the motor 30, the rod (43) initially slides within the rack moving plate (50) to free the packets, and then the rack itself is acted upon, pushing the packets forward and further moving plate (50), to allow one packet to be dispensed. Succeeding packets are held by an elastic flap (53) carried on a transverse horizontal arm (52).

Title: 5-aminoaphthostyryl derivatives
IPC: C07D209/92
Filed: 1977-11-14
Abstract: A process for the preparation of 5-aminonaphthostyril of the general formula <IMAGE>  where     R = H or C1-C4-alkyl, R' = H, C1-C4-alkyl, cycloalkyl, arylakyl, C1-C4-cyanoalkyl or C1-C4-hydroxyalkyl and   R'' = R' but cannot be H, and R' and R'' together can form an optionally substituted ring which may or may not contain other heteroatoms, is characterised in that a direct amination of naphthostyril with N-chloramine is carried out in a system of the redox type in an acid reaction medium with a strong acid. Such a procedure makes it possible to obtain a general, eminently industrial method for the direct amination of naphthostyril and in particular via the alkylamination of the said substrates, without the need for complicated operations and successive reaction stages as compared with the processes of the known state of the art. Such compounds are in particular used in the field of fine chemicals and above all as intermediates in the field of dyes and pharmaceutical products.

Abstract: 1335192 Antistatic compositions STX 7 Oct 1970 [7 Oct 1969] 47747/70 Heading C3R [Also in Division D1] A composition for rendering fibrous materials and textiles antistatic comprises an aminoplast precondensate derived from melamine, formaldehyde and a polyethylene glycol of molecular weight from 500 to 6000 and a polyisocyanate dissolved in an anhydrous organic solvent. In practice the precondensate generally comprises 1 molar proportion of melamine, 4 to 6 molar proportions of formaldehyde and 2 to 3 molar proportions of the polyethylene glycol. The organic, aliphatic or aromatic, polyisocyanates used in the composition for cross-linking are generally either of the difunctional type such as tetramethylene diisocyanate, hexamethylene diisocyanate, toluene diisocyanate or 4,41-diphenyl diisocyanate methane or of the trifunctional type such as those which are, for example, obtained from 3 mols. of hexamethylene diisocyanate and one mol. of water or from 3 mols. of toluenediisocyanate condensed with 1 mol. of trimethylol propane. Conventional cross-linking catalysts may be used, such as zinc 2-ethyl hexanoate, tin 2-ethyl hexanoate and cobalt naphthenate. Examples of the organic solvent are aliphatic or aromatic monohalogenated or polyhalogenated compounds such as trichloroethylene, perchloroethylene, monochlorobenzene or a fluorinated solvent. The invention also provides a method of rendering fibrous materials and textiles antistatic by applying the above composition and cross-linking the precondensate. The textile materials are generally based on polyamides, polyesters and polyacrylics and on their mixtures.
