IPC: F16G1/28
Filed: 1995-04-13
Abstract: PURPOSE: To ensure even transmission characteristics, prevent belt wear and produce precise pulley synchronization by increasing the longitudinal stiffness of a pliable endless member with transversely oriented teeth. CONSTITUTION: This transmission with a fixed transmission ratio comprises a pliable endless member 1 provided with transversely oriented teeth 4, and at least two pulleys 2 and 3 each provided in their circumferential surface with recesses 5, 6 that mate with the teeth 4. The pliable member 1 is a flexible belt made of, for example, metal that is stiff in its longitudinal direction. Such a flexible metal belt advantageously undergoes only elastic deformation and thus no wear, and resists high temperature including the internal temperature of internal combustion engines. For precise synchronization between the two pulleys 2 and 3, the pitch of the teeth 4 of the belt 1 is selected smaller than that of the recesses 5 of the driving pulley 2 but larger than that of the recesses 6 of the driven pulley 3.

Title: Production of foam glass
Inventor: TERADA SHIYOUJI
IPC: C03C11/00
Filed: 1981-07-16
Abstract: PURPOSE:To make the easy production of foam glass possible by mixing a specific content of powdery hexagonal boron nitride as a foaming agent with the ground product of glass and melting the same. CONSTITUTION:Powder of hexagonal boron nitride is added as a foaming agent with the ground product of glass at 0.1-10wt% ratios basing on the weight of the ground product of glass. The molding of such mixture is heated to temps. above the softening temp. of the used glass, whereby foam glass is produced. The hexagonal boron nitride (BN) as a foaming agent is oxidized gradually in molten glass and turns to B2O3; at the same time, gaseous NO is generated, thus allowing the glass to foam. Not only conventional glass of Na2O-CaO- SiO2 system but also glass of Na20-B2O3-SiO2 system which is regarded difficult to produce foam glass are easily used for production of foam glass.
