Abstract: An antistatic moulding composition comprises (A) a graft copolymer of styrene and acrylonitrile on a polymer of a conjugated diolefin containing at least 80% by weight of polymerized diolefin and at most 20% of styrene, acrylonitrile or a mixture thereof, (C) a graft copolymer of styrene and acrylonitrile on a copolymer of a conjugated diene with an ester of an ethylenically unsaturated carboxylic acid and (D) an optionally etherified or esterified polypropylene glycol with a degree of polymerization of from 10 to 1000.  The styrene and acrylonitrile in (A) and (C) may be replaced by an alkyl styrene or alkylacrylonitrile, respectively, and the said monomers may be present as a resinous copolymer (B), as well as in polymers (A) and (C).  The diene in the graft copolymer backbones is preferably butadiene or isoprene and the ester in copolymer (C) is e.g. an ester of acrylic acid, methacrylic acid or fumaric acid. Other comonomers such as styrene, acrylonitrile, methyl vinyl ether, methacrylic acid, ethylene glycol diacrylate, butanediol diacrylate and divinyl benzene may be copolymerized with the diene and ester in the backbone of (C). The polypropylene glycol is blended with a coagulate of a mixture of latices of (A) and (C), or with a dry powder mixture of (A) and (C), or an emulsion of the polypropylene glycol is mixed with latices of (A) and (C) and the mixture is coagulated.  Stearates, waxes and other conventional ingredients may be incorporated in the composition. In Examples 1 to 6, (A) is of styrene and acrylonitrile, grafted on to polybutadiene, (B) is a styrene-acrylonitrile copolymer, (D) is a linear polypropylene glycol and (C) is of styrene and acrylonitrile grafted on to a copolymer of butadiene with n-butyl acrylate, ethyl acrylate, di-n-butyl fumarate or methyl methacrylate.

[Class 41] Strip material in the form of a thin sheathing 11, Figs. 1, 2 of resistant metal such as stainless steel rolled or pressed on to a backing 10 is electropolished by anodic treatment in an indiarubber or glass lined cell 13. The strip, which may be for instance of such sectional form as shown in Fig. 2, is fed over roller anodes 20 disposed under an appropriately shaped cathode 22, supported by and insulated from the axles 25 of the anodes. The electrolyte may comprise a saturated solution of potassium dichromate in strong H2SO4 to which has been added from 5 to 25 per cent of a sulphonated high molecular weight alcohol such as lauryl, cetyl, or stearyl alcohol. After treatment the strip passes over rollers 32 in a rinsing compartment 14 and is then dried by hot air in compartment 15. The openings in the compartment walls through which the strip passes are fitted with indiarubber dams 18, 28, and 34.

Title: Apparatus for feeding webs to textile machines, especially to clip-chain or pin-chain tenters
IPC: D06C3/00
Filed: 1946-02-28
Abstract: 608,898. Feeding webs. HEBERLEIN & CO., AKT.-GES. Feb. 28, 1946, No. 6277. Convention date, March 5, 1945. [Class 38 (iv)] [Also in Group XL (b)] In apparatus for feeding fabric into a textile machine, the movement of angularly movable guiding rollers is controlled by a light beam directed on to a photo-electric cell and influenced by the selvedge. The selvedge is gripped between two rollers 2, Fig. 13, carried in a bracket 14 which is supported on a rotatable spindle 3. The spindle carries a suitably shaped armature 13 between the poles of an electromagnet 15 which tends to turn the bracket 14 against the tension of a returning spring so that the orientation of the rollers, in performing their guiding function, depends on the current flowing. A lighting system 9 directs a beam on to a mirror 4 and thence to a photo-electric cell 8 so that the edge of the fabric 1, intercepting the beam to a greater or less extent, determines the amount of light reaching the cell. A suitable circuit is shown in Fig. 14. A power transformer, having a winding 22 connected across the mains, supplies the heater of a triode 26, the photo-electric cell 8, through a resistor 27 and the lamp 9. The mains voltage is connected directly through the control magnet 15, byepassed by a large condenser 29, to the anode of the triode 26. With this arrangement, increased light reaching the cell 8 causes decreased current flow in the magnet 15, the sensitivity being determined by the potentiometer 28. A heater 18, Fig. 13, may be placed below the mirror 4 to overcome any condensation of moisture. In an alternative form, the mirror is not used, the lamp and cell being on opposite sides of the fabric.

In multiplication by the decimal part of multiplier, the multiplicand is fed as a series of pulses through an appropriate number of binary coded decimal counters 11, 12 comprising bi-stable circuits arranged to feed each non-carry pulse to a matrix 7; thus, each decade produces pulses in the ratios 5, 2, 1, 1 to each 10 incoming pulses.

For multiplication by a number comprising an integral and a decimal part, two circuits of the above type are combined, coincidence being avoided by using sharp pulses, relatively widely spaced and subjecting the pulses in the integral part of the circuit to a slight delay (Fig. 3, not shown).

A high-speed reverse current trip mechanism having a core 1 surrounding a conductor 2 includes a permanent magnet 5 which normally attracts an armature 3 pivoted at 4, the arrangement being such that flux across the gap 1A in the core 1 due to normal current in the conductor 2 is in the same direction as the flux in the armature 3 due to the permanent magnet 5, whereby the armature is retained across the permanent magnet. Reverse current above a predetermined value induces a reverse flux to overcome the permanent magnet flux in the armature so that it is quickly moved to bridge the gap 1A and trip a circuit-breaker (not shown) or other apparatus, the permanent flux then traversing a by-pass member 5a. Springs such as that shown at 6 may bias the armature in either direction.
