Abstract: A dry composition comprises, by weight, 35 to 60 parts of unswollen starch, 35 to 60 parts of polyvinyl alcohol and 5 to 11 parts of sodium carboxymethyl cellulose and preferably also 2 parts of an inorganic salt such as ammonium sulphate, 0.5 parts of an aldehyde such as formaldehyde or paraformaldehyde and 0.5 parts of a preservative such as benzoic acid, the total parts of the named ingredients being 100.  The polyvinyl alcohol preferably has a viscosity of between 5 centipoises and 80 centipoises measured at a 4% aqueous solution, by weight, at 20 DEG  C., and preferably has a vinyl ester content not exceeding 5% by weight. The sodium carboxymethylcellulose preferably has a viscosity of from 18 centipoises measured at 2% aqueous solution, by weight, at 25 DEG  C. When the composition is heated in water in a proportion such that the solids concentration is 1 to 12% by weight, at a temperature of 180 DEG  to 200 DEG  F., until the starch has been swollen and the other ingredients dissolved, an adhesive is produced which is water-resistant and can be used to bond a plurality of cellulosic structures, e.g. kraft plies.ALSO:A dry composition comprises, by weight, 35 to 60 parts of unswollen starch, 35 to 60 parts of polyvinyl alcohol and 5 to 11 parts of sodium carboxylmethyl cellulose and preferably also 2 parts of an inorganic salt such as ammonium sulphate, 0,5 parts of an aldehyde such as formaldehyde or paraformaldehyde and 0,5 parts of a preservative such as benzoic acid, the total parts of the named ingredients being 100.

Hg, introducing an inert gas preheated to 160‹ to 200‹ C. countercurrently at the base of the column; withdrawing overhead those impurities having a boiling point lower than that of the respective 2,5-dioxo-1- oxa-2-phospholane, together with the inert gas; withdrawing the 2,5-dioxo-1-oxa-2-phospholane thus freed from low-boiling impurities from the base of the distilling column and passing it to a film evaporator; and distilling off the 2,5-dioxo- 1-oxa-2-phospholane from higher-boiling impurities in the film evaporator under a pressure of 0À1 to 5 mm. Hg. Specified inert gases are nitrogen and air and the increase in temperature from the top tray to the bottom tray is intended to mean that temperature increments occur between successive trays or successive groups, e.g. pairs, of trays. Suitable apparatus is described with reference to a drawing (not shown) and examples are given for the purification of the 2-methyl- and 2-phenyl compounds. The products are useful for condensation with polyester-forming reactants to give products which may be formed into filaments, fibres, sheets or articles having flame-retardant properties.

IPC: F02M1/00
Filed: 1967-06-26
Abstract: 1,211,855. Treating charge. J.R. CHHABRA. June 24, 1968 [June 26, 1967], No.29355/67. Heading F1B. In an I. C, engine the fuel/air mixture discharged from mixing means, e.g. a carburetter 2, Fig. 4, passes through a movable perforated diffusing device into the induction manifold 1. The device comprises a circular screen 15 and a generally semi-circular screen 16 both of copper wire mesh, and is pivotally mounted on a fixed tube 11 so as to operate in the manner of a butterfly valve. A lead weight 17 biases the device into the closed and fully diffusing position shown. When the engine speed increases, the increase in flow in the manifold 1 causes the device to move towards a fully open and ineffective position. A tube 12 of copper wire mesh or of imperforate sheet material, prevents fuel collecting on and running along the wall of curved passage 10. The tube 11 is heated by exhaust gases received and returned to the engine exhaust pipe (4), Figs.1 to 3 (not shown), via pipes (5) and (6). A pre-heater coil may be arranged around the tube 11 externally of the manifold 1 to heat the tube 11 before the engine has warmed up. The carburetter butterfly throttle valve, when in its fully open position, acts as a stop for the device and prevents flutter thereof. Alternatively, a separate stop may be provided. The engine may be of the type in which fuel is injected into an air inlet passage.

[Class 60.] New or worn dies are shaped by a reciprocating wire, which may carry a shaped grinding element the dies being mounted in a holder rotating at high speed, and the wire being set to the required angle with the aid of a gauge. As shown, a die 16 is carried'by a holder 15, mounted in a disc 14, supported in turn in an annular rotating member 12 driven by gearing 25, 30, 31 from a shaft 32. The shaft also carries crank arms 34 for the reciprocation of a wire 35, suitably guided by pulleys 36, 37, and tensioned by a spring. The pulleys are adjustable as to height by mounting in a slotted frame 38 and a gauge 44 also mounted in the frame is used for setting the angle of approach of the wire to the die. The gauge comprises, as shown in Fig. 8, a pivoted member 42 provided with a straight edge at 44 and a pointer moving over a scale 41. A shaped grinding element 47 may be mounted on the wire to remove worn parts not capable of removal by the wire without too large an alteration in the die. The element 47 has a barrel part slightly tapered and is bored to fit on the wire and abrasive is supplied to its inner end. A stop 48 prevents rotation by contact with the rotating die.

[Class 100 (ii).] Rotary intaglio machines; tripping-arrangements; gripper mechanism.-A rotary intaglio proof - printing press is constructed so that cylinders 1 of different sizes can print on a sheet fed to grippers 10 on an impression cylinder 8, the machine being set so that after the cylinder 1 has made a given number of revolutions the grippers are operated to take the sheet and the impression cylinder is moved into printing position by the operation of a contact device. This contact device may be formed of single metal teeth 6, 7, Fig. 2, on gear wheels 4, 5 which gear the cylinders 1, 8 together,' the remaining teeth of the gears being made of fibre. To ensure correct register of the design, the tooth 6 may at the commencement of the operation be engaged with a gap 14 or 14<1> in the wheel 5, and since the gears 4, 5 have a different number of teeth, the teeth 6, 7 will engage after a. given number of revolutions and printing will then occur. To set the cylinders 1 correctly they may be fitted with pointers 2 which are set by the aid of a fixed scale 3 before the cylinders are rotated. Before setting the pointer 2 the impression cylinder is brought to a definite position. The cylinder 8 may be tripped at the end of the printing- operation by means of eccentric bearings 9 operated by a hand-lever.
