Title: Improvements in or relating to the chemical treatment of cellulosic materials to improve their water-resisting, crease-resisting, or other properties
IPC: D06M13/345
Filed: 1941-03-10
Abstract: 559,584. Cellulose derivatives; waterproofing cellulosic textile materials. DREYFUS, H. March 10, 1941, No. 3208. [Class 2 (ii)] [Also in Group VIII] Cellulosic materials are heated with and caused to react with carbylamines so as to modify their properties. The waterproof properties are improved if carbylamines containing alkyl radicals with a large number of carbon atoms, e.g. 10, 15, or more, are used. The resistance to creasing and, in the case of cellulose acetate, the safe-ironing point are increased by using compounds containing at least two carbylamine radicals. Suitable carbylamines may be obtained by reacting a mono- or poly-amine with chloroform in the presence of caustic potash or other caustic alkali, preferably under reflux. Thus, lauryl-, tridecyl-, and stearyl-carbylamines may be obtained from the corresponding amines, and ethylene, propylene, and hexamethylene dicarbylamines may be obtained from ethylene, propylene, and hexamethylene diamine. The cellulosic materials may be subjected to the action of carbylamine vapour at 110-140 C. for several hours, or they may be heated under reflux with a solution of carbylamine in a high boiling liquid such as tetra- or decahydronaphthalene, or they may be padded with a solution of carbylamine in benzene, toluene, ether, or acetone and then heated. The process is applicable to the treatment of fabrics, yarns, filaments, or fibres of cotton, linen, regenerated cellulose, cellulose acetate, or other cellulose derivative containing free hydroxy groups. The waterproofed materials may be used as or for making parachute fabrics ropes or cords, fishing nets, sails, or tents. Yarns or fabrics intended for dress or shirting materials or loose covers may be rendered crease-resistant by the process. In an example, a fabric of high tenacity cellulosic yarn, obtained by stretching cellulose acetate yarn in wet steam and then completely saponifying, is immersed in a benzene solution of stearylcarbylamine, removed, pressed, and heated at 110 C. If desired, it may be dried at a relatively low temperature before subjecting it to the heat treatment. The fabric is scoured with hot soap solution, washed and dried. Specifications 547,802 and 547,803 are referred to.

A blasting machine for cleaning, reconditioning, descaling, deburring or otherwise surface-treating elongated articles comprises a stationary blast housing 10 open at both ends and provided with blastant-throwing devices 30, a stationary housing 15 communicating with one end of the housing 10 and extending therefrom sufficiently to accommodate the full length of the longest workpiece to be treated, and a housing 35 movable from a position on the side of housing 10 opposite to housing 15 to a position within the housing 15. The movable housing 35 has rollers running on tracks 38 and is moved by a chain 75 driven by a power unit 78. With the housing 35 positioned within the housing 15, a workpiece 28, e.g. an engine crankcase casting, is loaded from above or from either side on to a car 25 having rollers running on tracks 20 and movable by a chain 79 driven by a power unit 80 (not shown). The housing 35 is then moved out from housing 15 to a position in which its end abuts a stationary end panel 40 having air inlet ducts; the end closure 16 of the housing 15 has air outlet manifolds leading to conduits 19 connected through suction ducts to a dust collector. The car 25 is then moved to carry the workpiece 28 through the blast housing 10 into the housing 15 and thereafter back through the blast housing 10 into the housing 35, this being repeated as often as necessary. The controls for the power untis 78, 80 may be manual or semi-automatic, and arranged to run the car 25 back and forth any predetermined number of times. When blasting is finished, the housing 35 is moved into the housing 15 and the workpiece unloaded from the car. Spent blastant is received in hoppers 50 delivering to a pair of tandem disposed reciprocating flight conveyers 52. The conveyers deliver to a screw conveyer 54 delivering to an elevator 55 in turn delivering to a conveyer 56 discharging into a sizing separator 58. Oversize debris is discharged to disposal through conduit 59, and fine debris is discharged to disposal through conduit 60. Removable blastant passes through conduit 62 to an elevator 64 and thence by conveyer 66 to hoppers 68, 69 from which it flows by gravity through conduits 70 to the blast devices 30.

Title: Improvements in Glass Blowing Machines.
Inventor: WILZIN ARTHUR
IPC: C03B9/20
Filed: 1916-03-13
Abstract: 104,722. Wilzin, A. March 13, 1916. Blowing.-The parison mould and gathering ladle of a glass-blowing machine are movable in paths at rightangles to one another, and the parison mould and finishing-mould are arranged in different horizontal planes. The neck mould is also movable vertically in relation to the parison and finishing moulds. The parison mould 46, which moves along horizontal guide-rails 8, is brought into conjunction with the gathering-ladle only while being filled with molten glass, thus minimizing the period during which it is exposed to the heat of the furnace. The neck mould 39, Fig. 2, is pivoted to the flanged lower end of a tube 25, which is mounted in the carriage 9 of the parison mould, but is free to move vertically. A tubular piston 33 is contained within the tube 25, and to this piston is fixed an axial rod 34 carrying at its lower end a plunger 35, which enters the neck mould and forms the mouth of the bottle. A spring 38 forces the rod 34 upwards. When the glass is sucked up into the parison mould, the pressure of the atmosphere overcomes the resistance of the spring 38 before the molten glass reaches the neck mould, so that the piston 33, and therefore the plunger 35, moves downward until the plunger occupies its normal moulding position, shown in dotted lines. The tube 35 being free to slide vertically, the neck mould normally seats itself on the parison mould and makes joint therewith by its own weight, thus dispensing with the necessity of providing fine vertical adjustments between the moulds. When the parison mould has moved into position over the finishing-mould 59, Fig. 1, a member 65 on a movable bar 66 engages a collar 25a attached to the tube 25. This member thus holds the tube 25 and prevents the neck mould from falling when the parison mould is opened. The member 65 is then moved to lower the parison into the finishing mould for the completion of the blowing operation.

Abstract: 1,099,407. Fluid-pressure servomotor systems. NAUCHNO-ISSLEDOVATELSKY INSTITUT TEPLOENERGETICH-ESKOGO PRIBOROSTIOJENIYA. Jan. 28, 1965, No. 3758/65. Heading G3P. A fluid system having two modes of operation comprises a pneumo-mechanical unit 1 housing a bellows 2 having a nozzle 5 in its base part connected to a fluid supply 30 through conduit 6. The nozzle 5 co-operates with a ball 1 to control the pressure in the bellows, the ball being engaged by an abutment rod 10. The rod 10 passes between roller 16, 17 and the roller 17 is carried by a spring arm 18 urged into contact with a cam 19 on a rod 20 moved by fluid-pressure acting on a diaphragm 22. A valve 8 has a diaphragm 39 cooperating with a nozzle 40, the opposite sides of the diaphragm being connected to the pressure supply 30 and the conduit 6. A second valve 27 has a diaphragm set controlling nozzles 35, 36, the nozzle 35 being connected to a pressure supply P 2  and the nozzle 36 to a nozzle 40 of valve 8. The opposite end chambers of the valve 27 are connected to the output line 37 which is also connected to the exterior of bellows 2. The two modes of operation are effected by the presence or absence of a signal P 1  on the diaphragm 22. If a signal P 1  acts on diaphragm 22, the rod 20 moves upwards to allow disengagement of the roller 17 from the rod 10 which is thus free to move. The pressure P 1  also acts in valve 27 of open nozzle 35 and close nozzle 36 and the output pressure 37 is thus equal to the pressure supply P 2 . As the output pressure acts on the exterior of bellows 2, the bellows assumes a position in which the forces are equal. Under this action, the valve 8 has no effect. If the pressure signal P 1  is zero, the rod 10 is clamped by the rollers and the valves 8 and 27 then control the supply and exhaust of pressure to and from the output 37 to maintain a constant pressure set by the position of the rod 10. The rod 10 may be adjusted through a cam 15 to varying the setting of the output pressure.
