Abstract: A squeeze casting powdery mold releasing agent according to this invention consists of a granulated or powdery mixture of a lubricant, an organic polymer and a metal soap; wherein the lubricant is coated with the organic polymer or the metal soap. Therefore, the mold releasing agent allows productions of castings of high quality, in a squeeze casting work, with good workability and without worsening environmental situations.

Abstract: A permanent mold casting powdery mold releasing agent according to this invention consists of a granulated or powdery mixture of a lubricant, an organic polymer and a metal soap; wherein the lubricant is coated with the organic polymer or the metal soap. Therefore, the mold releasing agent allows productions of castings of high quality, in a parmanent mold casting work, with good workability and without worsening environmental situations.

Abstract: A low pressure die casting powdery mold releasing agent according to this invention consists of a granulated or powdery mixture of a lubricant, an organic polymer and a metal soap; wherein the lubricant is coated with the organic polymer or the metal soap. Therefore, the mold releasing agent allows productions of castings of high quality, in a squeeze casting work, with good workability and without worsening environmental situations.

Abstract: The powder lubricant for plunger device of this invention is a mixture of a powdered or granulated lubricant base material used for a lubricant in a solid form, with an organic compound giving an adhesion ability to the lubricant base material. The most outstanding feature of this invention is that the lubricant base material has the powdered or granulated form. Effect of this invention are that occurrence of defects inside products can be positively avoided, dangers such as fire etc. and environmental pollution can be prevented, and sliding of plunger can be made smooth to improve the workability.

Abstract: A die-casting powdery mold releasing agent according to this invention is a mold releasing agent comprising a mixture of powdery or granulated mold releasing base material composed of an inorganic compound as used for lubricant in a solid form and an organic compound giving adhesive property to the mold releasing agent, the both having powdery or granulated configurations, or configurations in which the organic compound is covered on the mold releasing base material. The mold releasing agent allows production of castings of high quality, in the die-casting method with good workability and without worsening environmental situations.

Abstract: A flow controller of a temperature-sensitive type provided with an initial condition setting mechanism comprises a valve; a valve seat; a bimetal support tube disposed around the valve and adapted to be rotated and angularly positioned by operating means; a bimetal wound between the valve and the bimetal support tube, and having ends fixed to the valve and the bimetal support tube, respectively; and a liquid passage formed through the valve and connected to a space in which the bimetal is disposed. The valve includes a closing portion which has a passage port and the valve seat includes a port adapted to face to the closing portion including the port, so that the relative position between the ports changes for automatically control the flow by virtue of the rotation of the valve caused by deformation of the bimetal in accordance with the change of the liquid temperature.

Abstract: The present invention provides a lubricant composition for metalworking at a temperature higher than 200.degree. C. which comprises as its active components (i) at least one alkali metal salts of phthalic acid and (ii) a glass composition comprising 20 to 70% by weight of P.sub.2 O.sub.5, 8 to 72% by weight of M.sub.2 O wherein M is an alkali metal and 0 to 80% by weight of B.sub.2 O.sub.3, the ratio of component (i) to component (ii) being about 10:90 to about 90:10 in a total amount of 100 parts by weight.
