Title: Process and apparatus for packing definite quantities by weight of pulverous material
IPC: B65B1/18
Filed: 1930-04-07
Abstract: 346,985. Packeting powdered materials ; automatic-feed weighers. MIDDELBOE, K., 33, Vestergade, Copenhagen. April 7, 1930, No. 11057. [Class 143.] A machine for filling valve bags with a definite weight of pulverous material comprises a filling tank rotatable about a vertical axis, and a number of filling spouts extending from the lower part of the filling tank and each adapted to serve as a carrier and as a feeding device for a valve bag, and each provided with an individual weighing mechanism supported by suitable means and rotating with and at the same speed as the tank, for weighing the contents of the valve bag and provided with a cut-off mechanism controlled by the weighing mechanism for regulating the feed of material to the valve bag. The rotating filling tank 1 is supplied with pulverous material 12 by way of a pipe 6, the pulverous material being maintained in a free-flowing condition by means of stirrers 9 and by the action of compressed air forced through a central pipe 10<11> and through orifices in a shield 11<1>. The base of the tank carries discharge pipes 13<1> each of which communicates, by way of a feed. slide 32, with a filling spout 13<111> movable in a vertical direction relative to the discharge pipe 13<1>. The filling spout is supported from a scale beam 15 by means of a rod 17 and lever 20, the scale beam being carried by a bracket 16 projecting from the tank. In using the machine, an operator attaches an empty valve bag to each filling spout 13<111> as it moves past him. As the bag passes a fixed rail 43, the rail depresses a lever 35 carried by the rotating tank, and the lever operating through a cord 34 opens the feed slide 32 to admit the material to the bag. When sufficient material has entered the bag, the rod 17 descends and a projection 42 releases a catch lever 40 and resilient pawl 38, thereby permitting the feed slide 32 to close under the. action of a'spring 33. A stationary rail 28 then raises a lever 22 and liberates the spoutcarrying lever 20 from the restraint of a pin 21. The weight of the bag swings the spout about the pivot 19 (the upper portion 13<11> of the spout being divided or resiliently jointed to permit of this movement) and the filled bag slides off the spout, for instance to a conveyer belt. A lug 18 carried on the rod 17 rests against the bag to maintain it on the filling spout until the release of the bag takes place. The lower ends of the spouts may be bent so as to point in. the direction of movement thereby facilitating the attachment of the bags. The outlets from the tank may be arranged so that their size is automatically reduced to give a dribble feed for the last stage of the filling. Dust is removed through. suction orifices 30 leading to a suction tube 44.

Title: Improvements in the production of shaped articles and filling materials of porous styrene polymers
Inventor: STASTNY FRITZ
IPC: C08J9/36
Filed: 1956-04-12
Abstract: Shaped articles of porous styrene polymers are made by coating a porous styrene polymer with a polyglycidyl ether of an epihalohydrin and a polyhydroxy compound (see Group IV (a)) and a hardening agent therefor.  Specified styrene polymers are polystyrene and copolymers of styrene with other mono- or di-vinyl compounds.  The coating may be by dipping, brushing or spraying, or by coating the inner surface of the mould in which the styrene polymer is to be expanded.  In Example 2 a rectangular plate of porous polystyrene is coated with a butane-triol/epichlorhydrin resin containing p,p1-diaminodiphenylmethane as hardener.ALSO:Shaped articles and filling materials of porous styrene polymers are made either by joining together particles (having a minimum particle size of about 0.5 mm.) of a porous styrene polymer with the aid of a polyglycidyl ether of an epihalohydrin and a polyhydroxy compound and a hardening agent therefor, or by coating a porous styrene polymer shaped article or filling material with such a compound.  Specified styrene polymers are polystyrene and copolymers of styrene with other mono- or divinyl compounds.  Specified blowing agents are sodium carbonate, azo-compounds, and volatile organic compounds, e.g. saturated hydrocarbons of b.p. 30-70 DEG  C. which do not dissolve polystyrene. Specified polyhydroxy compounds are glycol, butanediols, butanetriols, glycerine, trimethylolpropane, hexanediol, pentaerythritol, hydroquinone, resorcinol, 4,41-dihydroxydiphenyl dimethyl methane or the sulphone or oxide thereof.  The epoxy resins may be modified by monohydric alcohols (e.g. allyl), hardened by polybasic acids (e.g. phthalic, succinic, adipic) or amines (e.g. ethylenediamine, hexamethylenediamine, diethylenediamine, triethylenetetramine, cyclohexylamine, diaminocyclohexane, p,p1 - diaminodiphenylurea, N-cyclohexylpropylenediamine, p,p1 - diaminodiphenylmethane), and catalysed by FriedelCrafts' catalysts (e.g. aluminium chloride).  Hollow spaces in boats &c. may be filled, and lifebelts, floats, plates and insulating sheets made, with these materials.  In Example (I) spherical particles of porous polystyrene are mixed with an ethylene glycol/epichlorhydrin polymer and N-cyclohexylpropylene diamine, and the mixture used to insulate and give good buoyancy to the lateral walls of boats.  In Example (II) a plate of porous polystyrene is coated with a butanetriol-epichlorhydrin resin containing p,p1 - diaminodiphenylmethane as hardener.

Convention dates, April 14, 1934 and Aug. 31, 1934. [Classes 97 (i) and 98 (ii)] Relates to the taking and projection of photographs in relief with or without colour. The apparatus for taking is shown in Figs. 1 and 2 and comprises a lens O of large aperture, a screen E comprising at least two lenticular networks E 1, E of different pitch and curvature, a second lens H and a lenticular plate or film F. The lens O and screen E are mounted in an adjustable chamber K. A translucent and unpolished plate I is interposed in the focal plane common to both networks E<1>, E2. In order to reduce dispersion behind the plate I, a lens D of the Fresnel type may be used in association therewith or in substitution therefor. Alternatively, there may be arranged coincident with the plate I a lenticular network of lenses of less focal length than the network E <1>, as shown at the lower part of Fig. 2. Further, the members of the screen other than the lens D may be given either a simple rotary motion about the optical axis of the system or a gyratory motion by means of a crank-shaft M. For colour photography, a number of monochrome images may be recorded on the film by the interposition in front of the lens H of a polychrome filter. Alternatively, a number of optical systems H may be disposed parallel to the optical axis of the lens O and screen E, and each is provided with a filter appropriate to the colour record. All the records may be made on a single film or on separate films. Original films may be copied in an apparatus similar to the taking apparatus. The picture is projected by transmission through a screen of the kind used in taking, the relation of the pitch of the elementary images on the screen to the network nearest the observers being adapted to the depth of the hall. Specification 454,020 is referred to.
