Title: Method of preparing a colloidal suspension of graphite
IPC: C01B31/04
Filed: 1937-02-01
Abstract: Colloidal suspensions of graphite in oils, suitable for use as lubricants, are stabilized by the addition as protective colloids, of "elektrionized" or "voltolized" vegetable oils.  Graphite is ground with the oil vehicle and a small quantity of a vegetable oil which has been treated electrically with a high tension p  discharge in the presence of an ionizing gas is added as a protective colloid. Subsequently, after dilution with mineral oil, a small quantity of petroleum oil with a high tar content, rich in natural colloids, may be added.  The grinding is preferably effected in a rotary colloidal grinder cooled to maintain a temperature below 110 DEG  C.  The Specification as open to inspection under Sect. 91 comprises also the preparation of colloidal suspensions of graphite in aqueous media using as protective colloids either a tannate of zinc or tin or a mixture of gum arabic and gum tragacanth which latter may be preserved by the addition of a solution of thymol in glycol.  This subject-matter does not appear in the Specification as accepted.

Patent GB-605451-A (GB)
Title: Improvements in or relating to the manufacture of pre-cast concrete articles
Filed: 1945-02-13
Abstract: A hydraulic cement mix that contains a wetting, dispersing or frothing agent and is of such a consistency that it is not self-supporting is filled into moulds as they move past on a conveyer or the like, and the mix is then subjected in the moulds to the action of dry heat at a temperature between 150 DEG F. and 575 DEG F. until the individual articles in the moulds are capable of being removed from the moulds and handled without distortion, whereupon the articles are removed from the moulds.  In a modified procedure the articles are given a short partial treatment at a temperature between 150 DEG F. and 575 DEG F. and are then heated, while still in the moulds, to a temperature above that of the short partial treatment but not exceeding 600 DEG F., to complete the treatment.  The wetting &c. agent may be an alkali metal salt of a sulphated higher aliphatic alcohol.  Preferably the mix is discharged into a mould from a hopper having a discharge orifice, of the same width as the mould, the trailing edge of which is so disposed as to cut off the mix at the level of the top of the mould, and the mould then passes on the conveyer through a tunnel lehr in which the temperature at the exit is higher than that at the entry, the extremes lying between 150 DEG F. and 600 DEG F.  The temperature may rise uniformly or may have a maximum at an intermediate point.  In this case heat may be supplied to the lehr at an intermediate point, air being made to flow from the exit to the entry end.  The hopper may be provided with means for forcing the mix through the discharge orifice, and the moulds may be adapted to open and close automatically as the conveyer passes over driving wheels at each end thereof.  Air may be introduced into the mix by jets, nozzles or the like, during mixing, and a substance such as calcium chloride may be incorporated to hasten the setting. Specification 566,142 is referred to.

A tube or ring is formed by packing slightly more material, e.g. uncured rubber, than is required to form the finished article into a casing 27, closed at its lower end by a hydraulically operated mandrel 21. A piston 33 is placed on the material, and an end plate 30 is fixed to the top of the casing by arms 32. A hydraulic pressure-head 39 is lowered against the piston 33, until the pressure in the cylinder 37 increases to a predetermined value at which a relief valve 45 comes into operation. The mandrel 21 is then forced up slowly through the material, while the pressure is maintained constant by the cylinder 37 and the valve 45, until the mandrel engages in a conical recess in the piston and the piston abuts against the end plate 30. Excess material escapes through a hole 34<SP>1</SP> in the piston. The pressure-head is raised, by fluid pressure, and the unit comprising the casing 27, the piston 33, and the mandrel 21 are removed along rails 25 and 26 and placed in a curing chamber. After curing, the mandrel is ejected, e.g. by a ram. The machine may be used the other way up. The relief valve may be replaced by a variable escape orifice. Liners 29 may be used to make tubes of various sizes. The mandrel and the inner surfaces of the liners may be chromium plated.
