Title: Adhesive bandages
Inventor: WALL THOMAS H
IPC: B65D75/30
Filed: 1962-01-29
Abstract: 1,001,421. Making packages. MINNESOTA MINING & MANUFACTURING CO. Jan. 29, 1962, No. 3345/62. Heading B8C. [Also in Divisions A5 and B5] An adhesive bandage package unit comprises a folded adhesive bandage enclosed between a pair of panels 12, 14 sealed about their periphery, a flap 32 extending into the package from one panel 12 being removably adhered to the adhesive at one end 26 of the bandage and the other panel 14 being removably adhered to the adhesive at the other end of the bandage. The intermediate portion of the bandage carries an absorbent pad 24. At the end of each panel opposite to the end where the flap 32 is attached to one panel 12 is a finger tab 18, 20. When the finger tabs are pulled apart the panels separate and the bandage is unfolded to expose the pad for application to the body. Further pulling on the tabs peels the flap and the other panel, respectively, from the adhesive coated ends of the bandage. Such bandage package units are made by laying absorbent strips 40 on a pressure-sensitive adhesive coated polyethylene backing web 34 and partially covering each strip and the portions of the web, which will form the adhesive end portions 26 at one end of each bandage, with a polyethylene strip 42 of a width slightly greater than the finished length of the flaps 32. The absorbent strips 40 are spaced by a distance equal to the sum of the lengths of the end portions 26, 28 of the bandage. The web is slit into strips 44 at right angles to the strips 40, 42 and alternate strips 44 are laid adhesive side down on a polyethylene web 46 for forming the covering panels 14, the web 46 having rectangles 47 printed thereon within which the backing web portions forming the other adhesive end portions 28 of the bandages are positioned. Two portions 54, 56 of a folder bar are then disposed to grip between them the adhesive end portions 26 and the covering flap 32. The bar is rolled through 360 degrees as adjacent bandages are severed from one another, to fold the bandage so that it overlies the appropriate printed rectangle. The free end of each flap 32 is temporarily secured to the covering panel web 46 by an adhesive strip. A second web for forming the other panels 12 is laid over the folded bandage and the bandages are subjected to heat radiation, e.g. from an incandescent lamp with an elliptical reflector, and then pressed lightly together so that the panel web portions and the flaps become heat sealed along the lines of the printed rectangle which absorb sufficient heat for this purpose. The individual packages are then severed from one another and trimmed, this process removing the temporary adhesive strip.

Title: Improvements in or relating to motion transmitting mechanism
Inventor: ELLINGER JOHN HENRY
IPC: F16D71/04
Filed: 1956-02-06
Abstract: 821,234. Locking levers and rods. MINISTER OF WORKS. Feb. 6, 1957 [Feb. 6, 1956], No. 3580/56. Class 80 (3). [Also in Group XXIX] In mechanism for imparting rotary movement to a driven member during part of a larger movement executed by a driving member, the driven member is locked to the driving member for part of the movement of the latter and is then locked to a stationary member. As applied to a multi-vane louvre valve for controlling the flow of fluid, a rack drives an outer annulus 1 through teeth 13, the annulus 1 and an integral annulus 5 forming the driving member. An innermost annulus 2 integral with an annulus 4 forms the stationary member, and an inner annulus 3 comprising arcuate parts extending through slots in the joining wall of the annuli 2, 4 and arcuate intermediate pieces 10, forms the driven member connected to the vane. The inner annulus 2 is formed with four equally spaced cams 15 and the integral annulus 4 carries four radially movable plungers 17 and four radially movable plungers 16 co-operable with a set of cams 22, 23 rigid with the driving annulus 1. The inner driving annulus carries four radial plungers 25 in perforations 24, which plungers can co-operate with similar perforations 26 in the driven member 3. In operation, the plungers 25 connect positively the annulus 5 of the driving member and the driven member 3 for rotation by the driving annulus 1. The annulus 1 and inner annulus 5 move in a clockwise direction taking the driven member 3 with them until a plunger 16 held stationary by annulus 4, is contacted by a cam 22 to move radially inwards. This moves the plunger 25 inwards to the space between the cams 15 and causes the driven member 3 to be locked to the stationary member 2, 4 by the plungers 16, the driving member continuing to rotate. Reversal of the direction of the driving member reverses the operation of the mechanism. The invention may be applied to linear motion and may perform more than one cycle. As applied to a multi-louvre valve comprising sets of vanes 27, 28, 29 arranged that their opening and closing can be effected in predetermined sequence, the vanes are actuated through toothed racks 31, within hollow supports 30, engaging mechanisms according to the invention, each vane being connected to a driven member of a mechanism. The mechanisms are so arranged that the vanes 27, 28, 29 can open in predetermined overlapping sequence.

Title: Process for dyeing and printing materials containing ester groups with dispersion dyestuffs
IPC: D06P3/36
Filed: 1962-01-31
Abstract: Mono- or di-nitro-aryl-hydrazones, osazones or phthalazones derived from aliphatic, cyclo-aliphatic, aromatic, araliphatic or heterocyclic aldehydes or ketones which are insoluble or sparingly soluble in water are prepared by reacting nitro-aryl-hydrazines with the appropriate carbonyl compound, preferably in acid solution and, in the case of nitro-aryl hydrazones of aromatic carbonyl compounds having a carboxylic acid group in ortho position to the carbonyl group, with subsequent elimination of water to form the corresponding phthalazone. The following compounds are specified: 3,31,4,41-tetrachlorobenzophenone -, phenyl - o  - styrylketone- and p-(21-nitrophenyl)-benzophenone-dinitrophenylhydrazone and compounds of the following formulae in which <FORM:0940256/C3/1>ALSO:Materials containing ester groups such as fibres and fabrics of cellulose acetate or aromatic polyesters are dyed or printed using as dyestuffs mono- or di-nitro-aryl-hydrazones, osazones or phthalazones derived from aliphatic, cycloaliphatic, aromatic, araliphatic or heterocyclic aldehydes or ketones which are insoluble or sparingly soluble in water.  The dyestuffs do not impart a colour to cotton and may be used to dye mixed fabrics containing only a proportion of material containing ester groups. The dyes may be transformed into aqueous dispersions of particle size about 1m  by precipitation from a water-miscible solvent or sulphuric acid followed by grinding whilst adding conventional dispersing agents e.g. ethylene oxide condensates with higher aliphatic alcohols.  Polyester materials may be dyed in the presence of a carrier at 80-125 DEG C. or without carriers at 100-140 DEG C., possibly with the addition of dispersing agents. Printing and padding may be effected from a thickened solution and the dye fixed at elevated temperature with or without steam. Examples are given in which numerous dyes are specified.

Abstract: 850,954. Photographic vesicular print materials. GENERAL ANILINE & FILM CORPORATION. Feb. 5, 1958 [Feb. 7, 1957], No. 3807/58. Class 98(2) Finely divided particles of an aromatic lightsensitive compound having at least a nitrogen atom multiply linked to another nitrogen atom and capable of generating gas on exposure are uniformly dispersed in a matrix of hydrophobic resin or cellulose ester so that substantially all of the particles are encased in the matrix, the dispersion being effected in the presence of a solvent for the resin but which does not dissolve the light-sensitive compound, and in the absence of a coupling component; and such dispersion is coated and dried to form a layer showing little light scattering or opalescence and suitable for vesicular procedure. In Example I a preformed film of cellulose acetate is coated with a toluene solution of polystyrene containing 2- diazo naphthol-(1)-5-sulphonic acid sodium salt which had been ball-milled in toluene before and also after mixing with the resin solution and dried and facsimile copies of an original are made therefrom by four procedures, (1) exposing to ultraviolet light to liberate the gas and heating in contact with a printed or similar surface to soften the resin, expand the gas, and form a bubble, positive, image, (2) similarly, particularly for a typewritten or embossed original, heating in contact with the non-image side of the latter, (3) exposing under an original and passing round an ironing mangle to make a negative bubble image, and (4) exposing under an original, storing to allow the gas to escape, exposing without the original to form a gas in the non-irradiated areas and heating, to form a positive bubble image. Seven further examples refer to Example I for procedure but specify an extensive variety of supports, resins, lightsensitive compounds and solvents for the purpose; the last of these examples, VIII, indicating a method avoiding the ball-milling operation with the sensitising material. Specifications 402,737, 538,869, 699,412, 712,966 and 723,883 are referred to.
