Title: Improvements in and relating to the production of paints, lacquers and the like
IPC: C09B67/20
Filed: 1933-09-13
Abstract: Colloidal dispersions of pigments in paint media, such as linseed oil, chinawood oil, pyroxylin, natural or synthetic resins, phenolformaldehyde condensation products, chlorinated rubber or rubber-like substances such as the reaction products of ethylene dichloride and polysulphide, are obtained by first massing or agglutinating the pigment with the medium and then subjecting the said mass in the state of a highly viscous plastic of leather-like consistency to a mechanical treatment adapted to set up high shearing stresses therein.  The initial step may be carried out in an internal mixing machine or by means of a roller mill commonly used in the rubber industry.  The mass resulting from this treatment is modified if required to bring it to the consistency described above by alteration of temperature, or removal or addition of suitable solvents.  The mass may be then treated by extrusion through a wire mesh strainer, with a mesh varying from \ba1/4\be inch to \ba1/100\be inch, or through a series of such strainers.  Alternatively the mass may be treated in roller mills, maintained at a temperature conducive to stiff consistency of the material being treated.  Preferably the rolls are operated differentially, a ratio of 1\ba1/4\be : 1 with the slower roll rotating at 24 r.p.m. being suitable.  The gap between the rolls is preferably approximately one-sixteenth inch or less. According to examples: (1) 8,3 lbs. of half-second nitrocotton containing 30 per cent alcohol was massed with 1 lb. carbon black in an internal mixing machine.  The resulting mass was then passed through a two-roll mill, the speed of the rolls being 1\ba1/4\be : 1 and the gap being adjusted to deliver a sheet of material not over one thirty-second inch in thickness.  The mass was then dissolved in butyl acetate to form a lacquer.  A small amount of butyl acetate may be added to facilitate the initial agglutination, and allowed to evaporate before the second operation; (2) 1000 gms. phenol formaldehyde resin was mixed with 500 gms. carbon black on a two-roll mill and then 500 gms. ester gum were added.  The mass was then treated until it attained the desired consistency, the rolls being about \ba1/4\be inch apart. The product was then passed through a second mill operating as described in the first example, and cold water was circulated through the rolls to give the mass the required leather-like consistency.  The product gave a lacquer on dissolving in butyl acetate.  The dispersion may contain some or all of the various constituents of the final paint or lacquer, and similarly the pigments may be added in stages if desired.  Suitable pigments include carbon black, zinc oxide, iron oxide, titanium oxide, dyes, lakes and toners commonly used in paint manufacture.

An epoxy resin composition has a viscosity between 90 and 150 poises at 25‹ C. and a volatility content (i.e. the percentage of volatile components lost after heating for 3 hours at 140‹ C., DIN 16945, August, 1966) of <0À3% by wt. It comprises: (A) a liquid polyglycidyl ether of diphenylolpropane (DPP) obtained by reacting from 4 to 8 moles of epichlorohydrin with 1 mole of DPP; and (B) from 0À5-10% by wt. of (A) of a reactive diluent having a viscosity of < 20 poises at 25‹ C. and a " volatility value " of < 25 which may be either a glycidyl ester of a monocarboxylic acid, which acid has at least 12 carbon atoms, e.g. glycidyl laurate, or a glycidyl ether of a polyhydric alcohol, e.g. 1,1,1-trimethylolpropane. Volatility value is defined as (Vc-Vr)/D, where Vc is the volatility content of the composition, Vr is the volatility content of the liquid polyglycidyl ether per se and D is the concentration of the reactive diluent in per cent by weight based on the polyglycidyl ether of DPP. The compositions of the invention have a much reduced tendency to crystallize on storage compared with conventional polyglycidyl ethers of DPP using a higher proportion of epichlorohydrin. They may be cured with conventional hardener to give products having high heat distortion temperatures.

Abstract: 877,766. Vertical take-off aircraft. SOC. BERTIN & CIE. Aug. 13, 1958 [Aug. 28, 1957], No. 26008/58. Addition to 847,500. Class 4. [Also in Groups XXVI and XXVIII] A conduit for conveying a flow of fluid comprises a convergent duct having an open end and bounded by a physical wall which is integral with a pressure chamber extending outside the duct in the vicinity of the open end thereof, the pressure chamber being supplied with pressure fluid and discharging this fluid in the form of a jet through a nozzle which extends along the periphery of the open end of the duct and which opens in a direction diverging slightly from the flow direction through the open end of the duct. The fluid jet issuing from the nozzle thus forms a divergent fluid wall which extends the convergent physical wall of the duct and forms a boundary for the flow of fluid downstream of the open end of the duct. A fan is disposed within, the convergent duct at the narrow end thereof so as to cause fluid flow through the duct in the direction of convergence. In Fig. 1 the convergent portion of the conduit comprises a physical wall 1 on the outside of which is a chamber 4 supplied with fluid under pressure from inlet 5, the fluid discharging from the chamber 4 through an annular nozzle 3 so as to form a divergent fluid wall 6. A fan 12 is mounted at the throat of the convergentdivergent duct so formed so as to accelerate the flow of the main stream of fluid f. In a second embodiment a divergent duct is disposed downstream of the divergent fluid wall so as to extend the latter. In Fig. 3 the fan 12 is driven by means of turbine blades 14 mounted at the periphery thereof, the turbine blades being acted upon by the fluid under pressure passing from the chamber 4 to the annular discharge nozzle 3 to form the divergent fluid wall 6. The device is mounted in an aircraft wing 15 so as to produce lift. The fluid under pressure supplied to the chamber 4 may be hot gases discharging from a gas turbine engine or a free piston gas generator. Specification 825,957 also is referred to.

Abstract: 801,346. Hydraulic accumulators. GRATZMULLER, J. L. Aug. 27, 1956 [Sept. 3, 1955], No. 26114/56. Class 69 (2). To ensure that an accululator will supply a minimum pressure, or alternatively will supply no pressure, a piston 2 (Fig. 4) engages a valve 7 if the piston moves beyond the end of its normal operative stroke and opens the valve to exhaust via a normally open valve 35 and a passage 28, thereby rendering inoperative the hydraulic system, which is connected to a port 5. The accumulator has oil in the portion 4 and the other side of the piston is loaded by air, by a spring, or by a weight. A lever 40 is provided to close the valve 35 when the accumulator is filled. In a modification (Fig. 3) the extension of the valve 7 that engages the piston is dispensed with and the pressure in the portion 4 acts on the top of the valve 22 via ducts 41 and assists a spring 11 in keeping the valve closed. Three rods 7a spaced at 120 degrees project into the cylinder 1 and are engaged by the piston 2 and lift the valve by abutting a large flange 30 on the valve.

Abstract: 830,269. Dip-moulding plastic footwear. GRUBER, H. Aug. 28, 1956, No. 26219/56. Class 87(2). Plastic footwear is manufactured in a threestage process : heating dip-forms 11 in an oven ; dipping them in plastic material 23 ; and then gelatinising the layer so formed in another oven. A pair of the dip-forms are connected to a plate 10 which is supported on two slide bars 5, Fig. 1, (not shown) in such manner that the dipforms travel along said bars through the oven when a projection on a carrier chain makes contact with plate 10. The heated plate and dipforms are then secured to a pivoted member 15 with a frame 14 which enables them to be swung easily into a tub 12 of plastic material 23 and to be held at an angle to the vertical in or above the tub to obtain a coating of plastic material which is thickened in a selected port. The tub in operation (i.e. to form the basic plastic coating) is raised towards the vertical dip-forms on a piston-operated lift-plate 19. In the gelatinising oven, two carrier chains 28 support a spear-like member 27, which is passed through the plate 10 between the coated dip-forms, and also incorporate projections 29 which force the spear-like member along the oven. A pinion 26 on the spear-like member engages a chain 39 above the carrier chain and causes the dip-forms to rotate to promote the uniform gelatinisation of the plastic film.

Abstract: 839,554. Overload-release clutches. SCHRO TER, K., and WALTERSCHEID-MULLER, B. Aug. 28, 1956 [March 27, 1956], No. 26325/56. Class 80 (2). A clutch which, on overload, is automatically disengaged and remains so until the speed of the input member 1 is reduced to within a predetermined difference from that of the output member 13, comprises an intermediate sleeve 9 having axially slidable thereon, by pin-and-slot connection 17, a member 7 having a pair of facial projections pressed against a stepped cam face 5, Fig. 3, on a member 2, fast to the input member 1, by one end of one or more springs 8 the other end of which abuts on a flange of the intermediate sleeve 9 to cause holes 16 in the flange to engage clutch pins 15 on the output member 13. When, on overload, the member 7 rides over the crest 11 and down the cam face 6 of the input member 2, the spring 8 expands and becomes sufficiently free of stress to permit a light spring 12 to thrust the intermediate sleeve 9 to the left (position shown), disengaging it from the output clutch pins 15. This declutched condition persists until the speed of the input member 1 is reduced to sufficiently near that of the output 13 to permit radially spring-pressed keys 21, Fig. 6, on the output member 13 to enter grooves 26 in the intermediate sleeve 9, whereupon the latter is turned to cause the member 7 to ride up the cam steps 4, 5 of the input member 2, re-stresssing the spring 8 which re-engages the intermediate'member 9 with the output clutch pins 15. The grooves 26 taper to a cylindrical surface to depress the Keys 21 to an inoperative position which the clutch is engaged, and their leading edges are set back radially to reject engagement of the keys 21 until the predetermined speed difference is reached. For a similar purpose the keys 21 have slight tangential freedom in opposition to springs 23.
