Title: Improvements in tape dispensing and handling
IPC: B65H35/00
Filed: 1939-10-12
Abstract: 533,129. Holders for rolls of tape &c. PHILLIPS, A. Oct. 12, 1939, No. 27695. [Class 18] Means for dispensing tape &c. consists of a box 11 containing a roll of tape, e.g. paper 14, hand-operated feed rolls 17, 18, guides for leading the tape to a delivery slot 19, water reservoir 24 and brush 25 for damping gummed tape and rollers 20, 21 over which a parcel 43 being sealed is pushed, and severing means 28 operated by a knee lever 38. One feed roller 17 is flattened at 29. When the rollers 17, 18 are turned one revolution, the end of the tape is fed from the cutting point so that it projects from the slot 19 and is then freed by the rollers 17, 18. The end of the tape may then be seized or attached to a parcel 43 and any length of tape may be drawn from the reel without hinderance, before it is severed by the cutter 28.

Title: Improvements in the manufacture and production of metal carbonyls
IPC: C01G1/04
Filed: 1928-09-27
Abstract: 324,382. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 27, 1928. Metal carbonyls.-In forming metal carbonyls by the action of carbon monoxide upon metals, the metal is formed by reducing the oxides contained, for example, in roasted pyrites or oxidic ores, at a temperature above 500‹ C., the reduction being carried out quickly and the reduced product being cooled quickly so as to avoid sintering. The reduction may be carried out in a rapid stream of reducing gas or with gas under pressure, or by passing the material through a revolving furnace from which it falls immediately after the reduction. The reduced material is cooled by passage through a chamber having external cooling ribs, or cooled by air or water, through which the cold reducing gas is passed. Hydrogen, carbon monoxide, hydrocarbons or solid carbon may be employed as reducing agents. When using reducing agents containing carbon. production of metal carbides is avoided, for example, when using methane by employing temperatures only slightly above 500‹ C., and when using carbon monoxide, by employing temperatures of 800-950‹ C. and diluting the gas with carbon dioxide. Specifications 256,428 and 259,407 are referred to.

Abstract: 616,896. Electric cables. SOC. ANON. DE TELECOMMUNICATIONSSept. 17, 1946. No. 27896. Convention date, Sept. 21, 1945. [Class 36] An apparatus for cutting out and positioning insulating discs on the central conductor of a coaxial cable punches the discs from a strip of insulating material, presses them into rotatary holders and positions them on the central conductor. Two plates 1, 2 carrying dies 3 are turned by the action of pawls 8, 9 on ratchetwheels 6, 7. Two punch holders 13 (Fig. 3) are controlled from driving shaft 12 and arranged so that one of the punches 14 operates each half revolution of said shaft 12. The plates 1, 2 move so that at the moment of operation of the punch 14 there is a die 3 opposite the punch. A disc is stamped from the insulating strip 15 and retained in the die 3. The operation is repeated by the second punch and the other plate when the shaft 12 has rotated another half turn. The punching operation is carried out at positions 16, 17, Fig. 2, and the discs carried round to positions 18, 19 where they are transferred, by channels in magazine 21, respectively to one end of a slot 26 in a plate 23 which is then slid to place the disc on the conductor 22 and to position the other end of the slot to receive a disc from the other plate. When one disc has just been ejected from position 18, another disc just attains position 19, and is ejected therefrom after half a turn of the shaft 12. The discs are held against movement, when being placed on the conductor, by two vanes 27, 28 coming together under the action of a double cam 29 on the shaft 11, this shaft having an eccentric 10 to actuate the pawls 8, 9 and a cam 24 to actuate the sliding slotted plate 23.

Abstract: 749,659. Artificial respiration appliances. ESPLEN, J. R. Oct. 13, 1954 [Oct. 14, 1953], No. 28259/53. Class 81(2). In artificial respiration apparatus the build-up and reduction of pressure in a conduit con. necting a gas supply to the lungs is controlled by an exhaust valve actuated by a pressure responsive bellows, bladder or the like. In the apparatus shown diagrammatically in the figure, air or oxygen is introduced through a pipe 20 and passes through a flexible tube 17 to the patient. It also passes through a pipe 36 and non-return valve 35 to a bellows 32 which, as it becomes inflated, tilts a chamber 22 until a ball 29 rolls off a flap 28 and opens an exhaust port 26. While the mask and chamber 16 are being exhausted to atmosphere through this port, the pressure in the bellows escapes through a pipe 37 and adjustable pinch cock 38. When the bellows is sufficiently deflated the ball 29 rolls back and closes the exhaust valve, so that the cycle is repeated. In the practical form of the apparatus the tilting of the chamber 22 is controlled by a spring of adjustable tension or the exhaust valve is actuated by spring or gravity controlled toggle mechanism, either directly or electrically. The bellows maybe replaced by a bladder or diaphragm.

Title: New complex metal compounds of monoazo-dyestuffs, and their manufacture and use
IPC: C09B62/012
Filed: 1959-08-20
Abstract: The invention comprises complex heavy metal compounds of monoazo dyes of formula <FORM:0904992/IV (b)/1> wherein A is the residue of a coupling component bound to the azo linkage in o-position to a hydroxyl group and X is a reactive substituent (i.e. a substituent capable of entering into true chemical combination with the cellulose fibre thereby anchoring the dye by a definite chemical or covalent bond and not by physical absorption or mechanical retention so that the dye cannot be removed from the fibre by washing with aqueous or organic solvents).  They are prepared by acylating a monoazo dye of formula <FORM:0904992/IV (b)/2> or a metal complex thereof with an anhydride or halide of an acid, the residue of which is capable of reacting with cellulose to form a covalent bond and metallising if necessary.  Specified acylating agents include cyanuric halides, halopyrimidines, acrylic chloride, propiolic chloride, chloromaleic anhydride, chloroacetyl chloride, b -bromo-or-chloro-propionic acid chooride, sulpho-chloro-acetic acid chloride and a :b -dichloropropionyl chloride.  The intermediate aminoazo dyes and their metal complexes are prepared by known methods.  Copper, cobalt and chromium complexes are specified.  If the dyestuff is readily metallisable, acylation may precede metallisation.  When the dyes are acylated with cyanuric chloride to give a primary condensation product a second halogen atom may be replaced by reaction with, e.g. an amine, alcohol or phenol.  The dyes may be used to colour wool, silk, leather, superpolyamides and especially cellulose fibres in the presence of an acid-binding agent in blue, green and red shades.  In an example the monoazo dye 6-nitro-1-amino- 2-naphthol-4-sulphonic acid --> 6-(41-carboxymethoxyphenyl)- amino-1-naphthol-3-sulphonic acid is treated with sodium sulphide, the aminoazo dye formed is refluxed in an alkaline solution of sodium chromo-salicyeate to give the 1:2-chromium complex which is condensed successively with cyanuric chloride and ammonia to give the monochlorotriazine dyestuff.  Many further examples are specified.  Specifications 797,946, 822,047, 838,337, 847,635, 848,742, 852,911, 870,047, 870,985, 885,814 and 885,815 are referred to.
