Abstract: A water purifying apparatus includes a water line extending from a source to a nozzle and having a filter, a sanitizing element and a venturi in the line. An ozone generator is connected to the venturi to supply ozonated air to the water flowing through the line. The ozone sanitizes the nozzle as water is discharged into a bottle.

Abstract: A pre-set and automatically operable means measures the plasticity of heated coal specimens or other material to be tested, and certain results thereof are indicated on visual read-out devices while other results are recorded in print-indicating instrumentalities, including signalling devices, are provided to keep the operator of the apparatus informed as to progress being made. A prime feature is the inclusion of several separate and closely adjacent specimen containers with the test specimen therein in heated condition, one of which may be in testing position while the other is in standby position with heated specimen intact and awaiting its turn to be moved into operating position.
