A reaction bonded ceramic body that has 50% to 60%, by weight, boron carbide, and 20% to 30%, by weight, silicon carbide. The reaction bonded ceramic body has least a portion of the boron carbide reacted with silicon to become siliconized boron carbide. Also, a method of making a reaction bonded ceramic material. The method may include the steps of forming a green body from a mixture of boron carbide, carbon, and an organic binder, and contacting the green body with a liquid infiltrant comprising silicon. The infiltrant has a temperature of about 1625° C. to about 1700° C. Furthermore, a method of making a reaction bonded boron carbide ceramic body. The method includes the steps of forming a green body from a mixture of boron carbide, carbon, and an organic binder. The weight ratio of boron carbide to carbon in the green body may be about 5:5 to 1 or more. The method also includes siliconizing a first portion of the boron carbide to siliconized boron carbide by contacting the green body with a molten silicon infiltrant, where the infiltrant has a temperature of about 1625° C. to about 1700° C. The method may further include dissolving a second portion of the boron carbide in the silicon infiltrant, where at least some of the dissolved boron carbide is reprecipated as smooth particulates.

A sanitizing method and a sanitizer system to be attached to a conventional circular bottle filling machine as used for filling beverage bottles, the system including a plurality of collector manifolds, each manifold being adapted to collect sanitizing liquid from a plurality of adjacent filler valves, there being a sufficient number of manifolds with plural valve engaging tubes to accommodate every filler valve of a particular machine; the manifolds are connectable by flexible hoses to a rotating collector which is preferably permanently installed at the top of the bottle filler machine so that the entry ports of the collector rotate with the rotating conveyor table of the machine and the exit port of the collector is from a stationary portion thereof. There is a provision for passage of carbon dioxide gas through the center of the collector in cases where the bottle filler machine employs an overhead supply conduit for carbon dioxide to maintain carbonation in the beverage in the filler bowl. Jacks are provided for the manifolds to hold them firmly up against the seals of the filler valves. Hoses are connectable to the manifolds by quick connect fittings and the rotating table is provided with retainers to hold the ends of the hoses while the sanitizer system is not in use and the machine is being used in a normal filling operation. The manifolds are completely removable and there is no modification required to the filler valves or other parts of the machine which might interfere with the normal filling operation.

A screeding device for screeding a concrete surface includes a support member, a screed head assembly mounted to the support member, and a control. The screed head assembly includes a grade setting device and a vibrating member, and is selectively movable in a screeding direction over and along the concrete surface by the support member. The vibrating member is vibratable to screed the concrete surface as the screed head assembly is moved in the screeding direction over and along the concrete surface. The control is operable to automatically stop vibration of the vibrating member when the support member is not moving the screed head assembly in the screeding direction and to automatically vibrate the vibrating member when the support member moves the screed head assembly in the screeding direction.
