Title: Improvements in and relating to the slingluff process of drawing sheet glass
IPC: C03B15/08
Filed: 1933-09-27
Abstract: 410,671. Glass manufacture. NAAMLOOZE VENNOOTSCHAP HOLLANDSCHE MAATSCHAPPIJ VOOR DE VERVAARDIGING VAN GLAS, 104, Weteringschans, Amsterdam. Sept. 27, 1933, No. 26595. Convention date, Feb. 20. [Class 56.] Relates to the production of sheet glass by means of drawing-apparatus of the Slingluff type in which a sheet a is drawn vertically upwards from molten glass contained in a drawing-tank b. It is found that a seam a<1> is frequently formed on the sheet parallel with its edges and in proximity to a zone c of cooler glass that extends between the sheet and the front wall b of the drawing-tank. According to the invention, the occurrence of the seam a<1> is prevented by heating the mass of glass close to the front wall of the tank at a point facing the origin of the seam, the mass of glass being cooled, if necessary, at other points close to the wall. The glass is heated by a burner g inserted in an aperture b<2> in the side of the tank and arranged to direct a long close flame on to the zone c where it meets the front wall of the tank, the flame being inclined to the plane of the glass sheet a. Apertures h may be formed in the tank wall to cool the adjacent glass and to allow burnt gases to escape. The glass may also be cooled by arranging water coolers above the glass in the corners of the tank, or by blowing air on the glass at these points. Coolers can also be placed against the outer walls of the tank for the same purpose. Specification 192,848, [Class 56], is referred to.

Title: Improvements in counter blow stamps and hammers
IPC: B21J7/34
Filed: 1946-09-06
Abstract: 631,954. Power hammers. MASSEY, Ltd., B. & S., and PICKWORTH, P. C. N. Sept. 6 1946, No. 26772. [Class 83 (iv)] In a hammer of the opposed double tup type, a single acting pressure fluid cylinder directly effects the downward movement of the upper tup and through fluid transmission means, the upward movement of the lower tup, the return movements being effected by a piston or pistons acting directly on the lower tup under the action of substantially constant pressure. At the top of the main frame 13 is a cylinder 14 to the top of which pressure fluid may be supplied by a pipe 15 in order to drive down a piston 16 whose rod 17 bears on the upper surface of the upper tup 11. The tup 11 is normally supported in the upper position by means of shoulders 11a resting on the upper ends of rods 27 which at their lower ends project into oil vessels 24, in which are also other pistons 26 having rods bearing on the underside of members 10a projecting from the lower tup or anvil 10. On the top of said projections bear the ends of rods 22 of pistons 21 in cylinders 20 supplied with pressure fluid at constant pressure by pipes 23. Fluid leaking past pistons 16 and 21 escapes by way of ports 14a and 20a respectively. In operation, admission of pressure fluid above the piston 16 forces down the upper tup 11 which, in turn, acts through rods 27, the oil in the vessels 24, and the pistons 26, to force up the lower tup 10. On the release of the pressure above the piston 16, the pressure above the pistons 21 acts directly to return the lower tup and indirectly through the oil transmission means and the rods 27 to return the upper tup. A spring 32 serves to cushion the piston 16 at the end of its downward movement and resilient pads or washers may be inserted between the tup 11 and the rods 27. Renewable inserts may be provided at the end of the piston-rod 17 and on the top of the tup 11.

Title: Eastomeric materials composed of segmented linear urea/urethane polymers
IPC: D01F6/72
Filed: 1965-06-29
Abstract: An elastomeric filament or film is made of a linear segmented urea/urethane/ether, ester or ether-ester polymer having an inherent viscosity of at least 3.0 when dissolved in 60% phenol and 40% tetrachloroethane and containing 2-9% of urea segments each containing one or more repeating units (1) -A-NH-CONH-D-NH-CO-NH- and/or (2) -ANHCONH-, where A is the residue of a functionally aliphatic di-isocyanate, and D the residue of a functionally aliphatic diamine NH2-D-NH2 the NH2 groups of which are not sterically hindered, A and D being such that a polyurea consisting solely of repeating units (1) and having a M.W. >104 would have a M.P. of at least 200 DEG  C., each of said urea segments being linked at the A end to the NH of a urethane linkage, the -O- of which is bonded to the residue P of a polyether, polyester or polyether-ester and at the -NH- end to the A of a urethane linkage -ANHCO-O, the -O- of which is attached to another P residue.  The polyethers, polyesters or polyether-esters used in making the polymers of the invention have the formula HO-P-OH, a molecular weight of 600-12,000 and a melting point below 50 DEG  C. They may be replaced by an oligomer of up to 11 P residues linked by urethane groups of formula -O-CO-NHANH-. The segmented linear polymers may be formed in a solution suitable for spinning or casting by forming a macrodiisocyanate from the polyether, polyester or polyether-ester and a diisocyanate, in a suitable solvent, adding water and/or the diamine and allowing reaction until the polymer in solution has an inherent viscosity of at least 2.  A small proportion of di-secondary diamine may be used with the di-primary diamine.  After formation of the macrodiisocyanate, some or all of the unreacted diisocyanate may be removed (Specification 1,118,736).  In the second stage of the process it is advantageous to employ a temperature of 55 DEG  C. or higher (Specification 1,118,734).  The spinning or coating solutions may be stabilized by addition of an organic acid anhydride or halide (Specification 1,118,735). Stabilizers for the filaments can also be added to the solution before spinning (Specification 1,118,736).  The co-polyethers (Specification 1,118,602) may be used in making the polymers of this invention.  Many other suitable polyols are mentioned.  The di-isocyanates may be sterically hindered or not. Preferred starting materials used in the examples are: Polyethers.-Copolymers of tetrahydrofurane and 8-oxabicyclo-[4.3.0]-nonane; polytetramethylene oxide. Diisocyanates.-Hexamethylene diisocyanate; 1,4 - cyclohexane bis - (methylisocyanate); p-xylylene diisocyanate.  Diamines.-Hexamethylene diamine; m- or p - xylylene diamine; 1,4 - cyclohexane bis-(methylamine); ethylene diamine; 4-methylheptane-1,7-diamine. The preferred solvent is N,N-dimethylacetamide.
