Abstract: A heat storage composition excellent in heat storing effect contains calcium chloride hexahydrate as the main component and an appropriate amount of a nucleating agent combination for inhibiting supercooling which is composed of barium sulfide, barium chloride dihydrate and strontium chloride hexahydrate or of barium chloride dihydrate and strontium chloride hexahydrate and optionally contains an appropriate amount of a thickening agent combination composed of an ultrafine silica powder and glycerin. Latent heat storage capsules contain the above heat storage composition and are improved particularly in their structure such that improved heat storage and release effects can be produced. A temperature control apparatus can make most of the heat storage capsules in the temperature control of a hothouse or the like.

Abstract: This invention relates to a latent heat accumulating greenhouse utilizing solar heat. The object of the invention is to provide a greenhouse which is simple in construction, of high efficiency for heat absorbing and capable of much absorbing and accumulating of heat. A heat accumulating chamber (B) partitioned by transparent sheets (1) is provided between the attic and a floor surface facing north in the greenhouse (A). A blower fan (2) is disposed to confront an opening (1a) provided at the lower portion in said heat accumulating chamber (B). Also, in the heat accumulating chamber (B), a heat accumulating unit (3) having a large number of light transmitting windows (32) and enclosing a phase transformation heat accumulating material (33) such as CaCl.sub.2.6H.sub.2 O, Na.sub.2 SO.sub.4.10H.sub.2 O therein is detachably suspended in a position close to windowpanes at the north side.

Abstract: A process comprising the steps of adding an inorganic foamed aggregate, an inorganic solid aggregate and a reinforcing fiber to cement to prepare a cement mixture, kneading the cement mixture with addition of 3 to 15% by weight of water based on the mixture to obtain a relatively hard kneaded mixture, press-molding the kneaded mixture at pressure of 200 to 600 kg/cm.sup.2, adding water to the molded piece to adjust the water content thereof, preheating the molded piece at a temperature of 40.degree. to 70.degree. C. before curing, spraying to the surface of the heated molded piece an aqueous dispersion prepared from resin and cement-type coloring material and containing inorganic particles 0.1 to 1.5 mm in size, drying the coated piece, applying a colored resin composition to the coating, and curing the resulting piece in an autoclave with pressurized steam, whereby a colored roofing panel or like cement product can be prepared.

Abstract: An apparatus for molding roofing panels having an insert portion extending from one end of the main body of the panel and offset stepwise from the surface of the main body. The apparatus comprises a lower die divided into a die segment for forming the insert portion and a die segment for forming the main body which have cavities conforming to the shapes of the insert portion and the main body of the panel respectively, and a movable hopper disposed to the front of the insert portion die segment and adapted to feed a material in a specified thickness. The main body die segment is initially held in its raised position with the bottoms of the two die segments positioned at the same level, and the movable hopper is reciprocated to feed the material into the combined cavity of the lower die to a uniform thickness. Subsequently an upper die is lowered into the lower die cavity to press the material, with the main body die segment also lowered by the amount of the offset of the panel insert portion.

Abstract: A cement panel reinforced with fibers comprising a base plate composed predominantly of inorganic fibers and a cement, an inner waterproof layer of a synthetic resin formed on a surface of the base plate, a coloring material layer composed predominantly of a cement and a pigment and formed on the inner waterproof layer, and a surface waterproof layer of a synthetic resin formed on the coloring material layer. The synthetic resin of the inner waterproof layer, having penetrated into both the base plate and the coloring material layer and solidified, gives a fastener effect, bonding them together.

Abstract: A panel feeder comprising a vacuum case having a vacuum suction opening at its front end and a closure in engagement with a stationary cover communicating with a vacuum source. The vacuum case is reciprocally slidingly movable by reciprocating means relative to a block of panels arranged substantially vertically side by side to cause the suction opening to feed the panels one by one by vacuum suction to a cutting apparatus operatively connected to the reciprocating means.
