A "glycol" pump is also provided on the conversion unit frame and is in fluid communication with the detergent tank on the de-icing machine which is used to contain "glycol" rather than detergent. The water heater is fluidly connected to the water pump on the de-icing machine and is fluidly connected to the spray nozzle on the aerial platform provided on the de-icing machine. A "glycol" proportioning valve is also provided adjacent the spray nozzle and is in fluid communication therewith.Type: GrantFiled: June 11, 1976Date of Patent: February 14, 1978Inventor: Walter E. Thorton-Trump

Patent number: 4046357Abstract: An air driven positive displacement pump is positioned to take a suction from a source of shotcrete accelerator. A shotcrete applicator tube receives pressurized shotcrete from a source thereof. A manifold is adapted to the applicator which has a first inlet connected to the output of the pump to receive accelerator at a pressure in excess of the pressure of the shotcrete passing through the applicator. The manifold also has a second inlet connected to an external source of compressed air to receive compressed air at a pressure higher than the pressure of the shotcrete passing through the shotcrete applicator. The manifold has a body in which the accelerator and compressed air from the first and second inlets respectively are intermixed. The manifold has at least two outlets positioned about the applicator to inject the accelerator and air mixture into shotcrete passing therethrough.Type: GrantFiled: December 3, 1976Date of Patent: September 6, 1977Assignee: Construction Systems & Equipment, Inc.Inventor: F. Shawn Twitchell

Patent number: 3945440Abstract: The fire extinguishing apparatus for oxy-acetylene welding assemblies having a cylinder having a free floating piston, over the actuator of a release valve, mountable at one end of a pressurized bottle containing a fire extinguishing fluid and connectable at its opposite end to an oxygen return line and a valve assembly connectable between the oxygen line and the torch, the valve assembly has a through passage for enabling passage of oxygen from the oxygen line to the torch and an intersecting passage having a manually operated shut-off valve intersecting the through passage at one end and having means at its opposite end for connection to the oxygen return line to the bottle of extinguishing fluid for enabling pressurized oxygen to flow to the cylinder and move the piston into operating engagement with the actuator of the release valve so as to release the fire extinguishing fluid therefrom. A discharge hose is extended from the fire extinguishing fluid bottle to the operator of the welding torch.Type: GrantFiled: June 23, 1975Date of Patent: March 23, 1976Inventor: August Edward Bohme
