Abstract: A heat transfer fluid having high heat capacity, high thermal loading capacity, low viscosity and low freezing point includes diphenyl oxide and 1,1 diphenyl ethane in broad proportions.

Abstract: A die cut and scored carton blank is formed into a carton. The carton blank is placed in a trough having a side wall and at least one retractable stop for turning upwardly elongate edge flaps of the carton blank, with the trough having two end walls for turning up end flaps of the carton blank. The partially-formed carton is then moved to a second position where it is lowered and horizontal glue strips are applied to an outer surface of an elongate edge flap. As the carton is moved toward the second position, glue strips are applied to end flaps of the carton blank. The partially-formed carton is then moved to an upper position, above the level of the trough, and into a compression chamber where side walls and end walls hold the flaps together until the glue hardens.

Abstract: Battery testing apparatus is provided for rapidly and automatically testing newly-manufactured electric batteries. The apparatus includes a testing machine which has at least one station, and preferably two, at which the batteries are tested for voltage and current output. By using two stations, the test at each station can be shorter and the change in the current output of a battery between the two stations helps to determine battery characteristics more effectively. Each of these stations has a stop for stopping a battery and a clamping arrangement for holding the battery at the station. Each station also has a pair of vertically movable terminal pads and a pair of horizontally movable terminal pads for top post batteries and side post batteries. The apparatus also includes an entry conveyor which is effective to supply one battery at a time to the stations of the machine and to effectively stop and hold a line of batteries to be tested.
