[Also in Division F2] A piston such as for an internal combustion engine, comprises a main body 1 of a light metal and cast inserts 2, 3 of a metal having a higher melting point than that of the body, the inserts being formed with irregular-shaped projections and recesses which are filled with the material of the body. The inserts, which may be of cast iron, are formed with the irregular shaped recesses and projections by first applying a bonding agent to the surface of a sand mould, and then sprinkling thereon a granular material, such as quartz sand or fine-grain calcium carbonate. The casting operation is then effected and the granular material released from the insert by a solvent such as hydrochloric acid thereby producing the projections and recesses. The insert may be secured to the piston body by moulding the light metal about the insert and vibrating the mould so that the metal completely fills the recesses. In an alternative method, an insert 2, Fig. 3 (not shown) is placed on a shoulder 4 in a die 5 and a light metal blank 11 subjected to pressure by a ram 6 until the light metal partly spreads around the insert. Upon subsequent pressure operations, the insert is completely secured in the blank and the latter hollowed out into a piston.

Abstract: 101,331. Davies, A. H., and United Newspapers, Ltd. June 29, 1916. Pile tables and supports for sheet feeds; sheet-separators; sheetregistering devices. - Relates to printing-machines for printing late news items on previously printed and folded newspapers, and consists in an improved construction of the mechanism for feeding the newspapers to the printing and impression cylinders without buckling the papers, so as to obtain perfect register of the impression. As shown, the newspapers are mounted on a pile table 7, and the top paper is fed to forwarding-rolls 6 by needles 30 on a pair of arms 28 secured in spaced relation on a shaft 16 free to rotate in arms 17 on shaft 18, which is rocked once for each revolution of the printing- cylinder 1 by lever mechanism operated by a cam on the shaft of the cylinder 1. The shaft 16 is also rocked once in each revolution of the printing-cylinder by crank 12 and lever mechanism 22. Pressing- rollers 25 are carried by struts 23 loosely mounted on the shaft 16 and normally hanging vertically against a fixed stop under the action of a spring. In operation, the arms 28 first swing into an approximately vertical position so that they engage the struts 23 and the needles engage the top paper. During the remainder of the forward swing, the struts are moved 'by the arms clear of the pile, and simultaneously the shaft 18 is rocked and the paper lifted into the nip of the rollers 6. The pile table is raised to keep the pile at a constant level by a rack 15 operated by ratchet mechanism 14, 14<a> actuated by the crank 12 and rod 13. The height of the pile is controlled by a yieldinglymounted roller 33 carried by a shaft 32 connected by lever mechanism 34 to the pawl 14, so as to lift the pawl from the ratchet-wheel 14a when the pile is at the correct height. The struts 23 are made adjustable in length, and the arms 28 are made in two parts pivoted together and held in line by a spring, so that during the return swing of the arms, the pin carrying parts of the arms may turn about their pivots to prevent damage to the containing newspaper. The front lays 36 are intermittently rocked by lever mechanism 37 and a cam on the shaft of the cylinder 1 to allow of the forward movement of the newspapers.

Patent GB-439237-A (GB)
Title: Improved method for the production of porous silica gel
IPC: C01B33/154
Filed: 1934-03-28
Abstract: Silica gel is obtained by preparing a silicic acid hydrosol having colloidal sulphur distributed therein, causing the hydrosol to gel, bleaching the gel free from soluble materials, mechanically working the moist product to form a smooth paste, shaping the paste, drying the formed paste and finally heating the dried product at a temperature sufficient to remove the sulphur. The gel may be prepared by reacting a solution of an alkali metal, e.g. sodium silicate with an excess of mineral acid, e.g. hydrochloric acid, the colloidal sulphur then being produced by the addition of a polysulphide of a metal not precipitated by the mineral acid, e.g. calcium polysulphide, in such quantity as to leave the solution neutral or slightly acid, or, according to the Provisional Specification, slightly alkaline.  The reactants may be mixed at temperatures of 40--80 DEG  C., preferably 40--60 DEG  C., a peptizing colloid, e.g. gum tragacanth or evaporated cellulose sulphite lye, may be added to the silicic acid hydrosol before the addition of the polysulphide solution.  The colloidal sulphur may also be introduced in the form of a pre-prepared colloidal solution.  The addition of the silicate solution to the mineral acid may be interrupted to permit the introduction of the polysulphide solution the remaining silicate being added subsequently.  If sulphuric acid is employed, an alkali metal polysulphide must be used.  Nitric acid may also be used.  The reacting solutions should be maintained in vigorous agitation. When the agitation is stopped the mixture sets to a gel which is preferably allowed to age.  The gel is then granulated say by being forced through a coarse screen and is washed, initially with dilute hydrochloric acid to remove any iron sulphide present. When free from soluble impurities it is ground to a paste in a disc mill, ball mill, edge runner, mill or the like, and the paste is moulded into shapes, say by extruding and cutting.  The shapes are then dried at raised temperature say 100--110 DEG  C., until superficially dry in a long pipe dryer and are then finally dried at 100--110 DEG  C., in an oven.  The removal of sulphur may be effected by heating at a gradually rising temperature up to 500-600 DEG  C.  Catalysts; sulphur trioxide.--Silica gels prepared as above are sprayed with a solution containing potassium vanadate and potassium sulphate.  The dried products containing vanadium pentoxide are used as a catalysts in the oxidation of sulphur dioxide-air mixtures at a temperature of either 438 or 498 DEG  C.  A silica gel prepared as before is sprayed with a solution containing platinic chloride and sugar.  After standing the product is heated to 250 DEG  C., and the resulting platinized carrier is employed as a catalyst in the oxidation of a sulphur dioxide-air mixture at 438 or 464 DEG  C.
