Title: Method of manufacturing poromeric materials
IPC: C08J9/28
Filed: 1973-08-17
Abstract: 1431110 Poromeric materials AKADEMIE DER WISSENSCHAFTEN DER DDR 17 Aug 1973 38891/73 Heading C3C A method of manufacturing poromeric materials, comprises mixing a monomeric or oligomeric or other polymerizable and/or crosslinkable and/or poly-adduct-forming substance or a mixture of the said substances with shaped solid particles which are liquefiable and/or evaporable by the action of heat, subjecting the resulting biphase or polyphase mixture to conditions, known per se, for initiating a polymerization reaction, and wholly or partially converting the chemically unreacted or partially reacted solid particles to the liquid and/or gaseous state by the action of heat which are wholly or partially driven out of the polymer. Partial chemical reaction of the solid particles with the remainder of the mixture may occur before and/or during and/or after the polymerization reaction. The solid particles may furthermore be totally or partially coated with a substance which causes secondary reactions with the pore surface produced in the remainder of the mixture and/or capable of reaction with the starting substance. The solid particles may be of equal or unequal size, and spherical, lamellar, irregular, needle-shaped or tubular. In order to obtain a pore size gradient across the cross-section, solid particles of different size or shape may be introduced layerwise into the other phase of the mixture. Inorganic fillers such as glass fibres, plasticizers, dyestuffs, and non-woven fabrics may also be added. The examples refer to adding trioxane granules to n-butyl acrylate (a) and a mixture of acrylic acid and glycerol (2) subjecting the mixture to electron radiation to polymerize the monomer(s) and then heating to remove the trioxane; adding naphthalene to a mixture of acrylic acid and glycerol (3) and subjecting the mixture as above; and adding trioxane to a mixture of acrylamide and glycerol which contains a fibre-glass fabric and subjecting the mixture again as above.

A shoe bottom roughing machine includes two roughing tools and at least two shoe carriers which carry the shoes around a closed path, the roughing tools being movable heightwise and tiltable lengthwise and widthwise of the shoe to accommodate the tools to the shape of the shoe bottom. Each shoe carrier consists of a base 8, a last pin 12 which can be tilted about pivot 21 by a screw 19 and a toe rest 13 which can be adjusted by screw 16. The carrier can be adjusted for length by pinion 14. Each carrier is pivoted by pin 9 to a lever 7 which in turn is pivoted to an arm on a rotary carrier 6. The shoe is guided in a straight line past the roughing tools by rollers 22, 23 engaging guide rails 24a, 24b and is guided around the rest of the closed path by guides 25, 26. A gear segment 33 and pinion 32 moves the lever 7 into its correct position at the start of the cycle. Each tool consists of a drum shaped body 71 housing resiliently mounted wire brushes 72 and is driven by gears 60, 61 and drive shaft 62. A guide plate 46 which contacts the shoe bottom ensures that only one part of the tool contacts the shoe bottom and roughs the shoe with an inwiping motion. To allow for lengthwise variations in the shoe the bearing 45 for the tool can tilt about pivots 40 in a frame 35. The frame 35 can be tilted widthwise of the shoe about pivot 47 and is locked in its adjusted position by a pin 49 engaging a toothed segment 48 on the frame 35. The frame 35 can also be moved widthwise of the shoe by means of slot 37 and is locked in position by a pin 39 engaging a toothed plate 38. The frame 35 is carried by a plate 36 which can move heightwise on guide rods 76. The lengthwise tilting of the tool is limited by a pin 44 and slot 42 and the tool may be locked in a tilted position when operating on the sole portions of shoes with very high arches. In a modification (not shown) the tool is moved widthwise of the shoe along the slot 37 by a sensing arm which contacts a cam track on the shoe carrier and which is connected to the frame 35 by a gear segment and a toothed rod.

An attitude and displacement indicator for a flight craft comprises a sphere 4, mounted for movement about axes X-X in accordance with displacement of the craft from a first predetermined reference, for example a localizer beam, for movement about axes Y-Y in accordance with the pitch attitude and for movement about axes Z-Z in accordance with the roll attitude of the craft; a band 12, positioned on the sphere, mounted for movement with the sphere about axes Y-Y and Z-Z, and for movement about axes X-X and Y-Y independent of the sphere in accordance with the displacement of the craft from a second predetermined reference for example a glide slope beam; the sphere 4 and band 12 being effective for indicating the pitch and roll attitude of the craft and the displacement of the craft from the first and second predetermined references. The indicator comprises a case 2 with a hollow sphere 4 mounted in it and divided into two hemispherical cups 6 and 8 by a painted horizon line 10. Centre band 12 with its axis in a horizontal plane is positioned around the sphere 4 and carries a symbol 14 representing the centre of glide slope and localiser beams. A symbol 16 representing the aircraft is fixed to the viewing aperture of the case 2 and flight director steering bars 18 and 20 are provided to give pitch and roll steering commands. The arrangement is such that the sphere has unlimited motion about axes ZZ and YY, and cups 6 and 8 and the centre band 12 have limited motion about the XX and YY axes respectively. Details are given of the mounting of the entire mechanism which is roll stabilized relative to the earth horizon. The indicator may be used in approach and landing mode of flight or in cruising flight. During the approach and landing the displacement symbol 14 moves vertically on the centre band to indicate the deviations from the glide slope beam and horizontally for deviations from the localizing beam. In cruising the sphere is rotated about the localizer displacement axis XX to remove the centre band 12 and the displacement symbol 14 from the viewing aperture of the case. The sphere is marked with a vertical scale (17), Fig. 5 (not shown), which, with the fixed aircraft symbol 16 indicates the pitch. The flight director steering bars 18 and 20 are arranged to move vertically in accordance with pitch command and about the ZZ axis in accordance with roll commands so that the pilot aligns the bars with the fixed symbol to place the craft on the desired flight path. In another embodiment the centre band may carry a reference mark corresponding to the level of the ground and be driven about the YY axis to indicate height above the ground.
