[Class 145 (i)] In a wood planing, moulding, or like machine, the top rolls 6 are mounted between swings 7 supported from below by rods 10 forming U-shaped supports at opposite sides of the machine which are connected bv a rod 11 carrying parallel arms 12 on the opposite ends of which are mounted unequal adjustable weights 13. An adjustment member 14 moved by a screw and hand wheel has secured thereto at 16, chains 17 passing over pulleys 18 and connected to the arms 12 on opposite sides of the rod 11 whereby the rolls can be lifted from the work. One end of a chain 21 is secured to the other end 20 of the adjustment member 14, passes over pulleys 22, 23, and its other end is secured at 24 to the arms 12 between the rod 11 and the smaller weight 13. The end 24 of the chain 21 thus acts as a fulcrum for the weighted levers 12 and is adjustable simultaneously with adjustment of the rolls. By suitable adjustment of the weights 13, the pressure exerted by the rolls on the timber can be made greater, equal to, or less than the dead weight of the rolls. In a modification, the adjustment member is connected to a pivoted triangular link which is connected by links to a cradle in which the rod rests, the weighted arms being pivoted on the cradle. Specification 261,944, [Class 145 (i)], is referred to.

Title: Improvements in and relating to biaxially oriented film
Inventor: HARRIS ROBIN
IPC: B29C48/10
Filed: 1965-05-04
Abstract: 1,107,354. Films. BAKELITE XYLONITE Ltd. 26 April, 1966 [4 May, 1965], No. 16739/65. Heading B5B. A process for the manufacture of biaxially oriented thermoplastic film-comprises extruding a tube of thermoplastic material from an annular die, and passing the tube through two pairs of nip rollers, the tube passing through the second pair of nip rollers at a rate greater than that at which it passed through the first, the diameter of the tube being expanded while it travels through the zone between the two sets of nip rollers, both sets of nip rollers being rotated at the same rate about the axis of the tube during its travel through the zone between them, the temperature of the tube as it passes through the first pair of nip rollers being adjusted so that the tube itself is not caused to rotate about its own axis by the first pair of nip rollers. Preferably, the portions of the tube surface folded by the first pair of nip rollers are also folded by the second pair of nip rollers. Specified thermoplastic materials include linear polyesters, vinylidene chloride homopolymers and copolymers, polyvinyl chloride, polyamides, homopolymers and copolymers of formaldehyde, polystyrene, and polyolefins, especially polypropylene. In operation, the tube is extruded from annular die 2 and passes over formers 7 through cooling system 5 in the quench bath 3 to nip rollers 4 and thence via guide rolls 13 to the stretching apparatus comprising in sequence a pre-nip heater 15, by which it is raised to a suitable temperature before passing through first nip rollers 14, thence through pre-heater 16, and a blow heater 17, by which its temperature is raised to the softening point, an upper air ring 18, guide rollers 20, a lower air ring 19, converging rollers 21, second nip rollers 22, cutters 23, and wind-up reels 24 and 25. Cutters 23, reels 24, 25, rollers 21 and nip rollers 14 and 22 are rotatable about a vertical axis coincident with the tube axis, and are rotated in operation by an electric motor, not shown. The formers 7 and guide rollers 20 are suitably made of "Teflon " (Registered Trade Mark). The rotary motion is not imparted to the tube. The pressure maintained between nip rollers 14 and 22 is sufficient to expand the tube, and the diameter is increased to the desired value. The tube then passes between air ring 18, the guide, rollers 20, and air ring 19, which cools it, and is then converged into the flattened form by the series of rollers 21 and the nip rollers 22, which are maintained out-of-phase with nip rollers 14 to ensure that the new edge folds which they make conicide with the edge lines caused by the nip rollers 14. The flattened tube is then slit by cutters 23 into two sheets which are wound up on reels 24 and 25.

Abstract: 688,675. Liquid fuel burners. ALADDIN INDUSTRIES. Inc. Aug. 9, 1951 [Aug. 17, 1950], No. 18824/51. Class 75(i) In a liquid fuel burner having a fuel control valve and a plurality of fuel dis-' charge orifices a device for cleaning the orifices comprises a movable member carrying a plurality of prickers and operated by mechanism extending to the outside of the burner and adapted to cause the prickers alternately to enter and leave first one or some of the orifices and then the other or others. The burner shown has two discharge orifices 46 which are cleaned by the ends of a pin 54 mounted on a reciprocating member 52. The latter is slidably engaged in a recess in a block 48 mounted on the top of a housing 26 welded to the upper end of a flat wick tube 24 extending upwardly from a fuel tank T and the operating mechanism to reciprocate the member 52 comprises a rocker bar 56 which extends through a slot in the block 48 to engage in a recess 52a in the reciprocating member and which at its lower end has a slot accommodating a pivot pin 74 traversing the housing 26 and a reduced eccentric portion 58e of a rotatable valve member 58 having a pointed end movable in and out of a fuel inlet aperture 40a in the housing 26; a dimple 24a is formed on the wick tube opposite the aperture 40a so that the fuel may have access thereto. The valve member is in threaded engagement with the inner end of a tube 60 extending outwardly from a bore in the side wall of the housing 26 and is rotated by a shaft 62 which extends in sealed manner through the tube and has wings at its inner end which engage in an axial slot in the valve member, the connection permitting relative axial movement of the shaft and the valve member. Several complete rotations of the shaft are needed to open or close the valve and each rotation causes each end of the cleaning pin 54 to enter and leave the corresponding discharge orifice. The mechanism is arranged so that when the cranked end 62b of the shaft is vertically upwards or downwards and also when the valve is fully open the reciprocating member is in its intermediate position with both ends of the cleaning pin withdrawn from the orifices. The burner head comprises a cap 42 which is held by a threaded sleeve on the upper end of the housing 26 and in which the discharge orifices are formed; a burner bowl 34 and a flame spreader 36 are secured to a plate 30 secured to both the housing 26 and the upper end of the wick tube. The fuel tank T comprises a shallow cylinder 14 closed by convex walls and the filling inlet is formed in the cylinder opposite the entrance of the flat wick tube and comprises a short tube 16 sealed into the tank and closed by a cover having an annular groove containing a gasket, the cover being secured by a sleeve 18 threaded to the outside of the short tube. At starting the fuel at the upper end of the wick tube is vaporized by a lighter 76.

IPC: C22C37/04
Filed: 1953-07-08
Abstract: Spheroidal graphite cast iron is made by adding to a molten bath of grey cast iron, containing not more than 0.05 per cent of sulphur, and at least 3 per cent of silicon, calcium in an amount of at least 0.5 per cent by weight of the bath, the temperature of the bath not exceeding 1500 DEG  C. and further silicon being added with the calcium, if desired and when additional silicon is necessary to give the bath a content of at least 3 per cent.  The bath may be desulphurized in any known manner, e.g. by the addition of granular calcium carbide in a stream of nitrogen through a consumable black iron pipe, before the addition of calcium.  It is stated that no advantage is obtained by increasing the silicon to more than 5.5 per cent or the added calcium to more than 1.5 per cent.  The calcium may be added as calcium silicide particularly if the bath requires an addition of silicon.  Reference has been directed by the Comptroller to Specification 700,626.
