Abstract: The process and apparatus for effecting savings of compressed injection gs such as oxygen or nitrogen when injecting solids such as burnt lime pneumatically into a receiving vessel, such as the blow-line to steel melt has a solids conveying system, a compressed gas supply source and a conduit and valve system functioning in a sequence, by which the compressed gas upon termination of the procedure is collected and thereupon is recycled. The system is equipped with at least one pressure-reservoir to collect the compressed gas from the previous procedure for recycling it.The pressure reservoir is subdivided by a reciprocating divider such as a membrane or a reciprocating piston to subdivide it into two parts of variable volumes, the divider is pushed by the returning compressed saved gas from one wall of the reservoir to the other. Highly compressed gas is blown into the empty part of the reservoir to increase the pressure upon the returned gas.

Abstract: A trigger valve which closes a main valve after a predetermined volume of fluid passes therethrough is equipped with a conversion mechanism arranged in the flow path of the fluid and functioning to translate the amount of fluid flowing through into a proportional amount of motion. A cam mechanism is turned by the conversion mechanism. The trigger valve closes the valve disk automatically due to the function of the cam mechanism when the fluid has flowed in a pre-determined quantity. Examples demonstrate the ability to control the valve means to increase or decrease a pre-determined standard flow of fluid at will by manipulations of a control mechanism.

Abstract: A protective alarm system for a vehicle or the like wherein a protective switch initiates operation of a circuit combining two timing effects : effecting time delaying of an alarm device, and determining the duration of the alarm. Once initiated by the protective switch, the alarm is actuated after a predetermined delay and for a predetermined duration despite any action on the switch such as a periodical opening and closing. Circuitry operated by a key switch defeats instantaneously actuation of the alarm system when a further manually operated knob is on, which results in a necessary order of operation, involving the possession of the key, to inhibit definitely the alarm.

Abstract: Apparatus for facilitating the loading and unloading of a motor truck. The rear spring suspension of the truck is fixed to and adjacent the rear ends of a pair of right and left flexible cantilever beams attached at their forward ends to the respective sides of the chassis or frame. The rear driving axle of the truck is connected with the transmission through a splined shaft variable in effective length. In normal driving the rear spring suspension is over the axle for direct support thereby. But when loading or unloading, the front wheels may be braked or blocked so that power operation of the rear wheels propels the axle forwardly and guidedly along the beams whereby the beams flex and allow the rear end of the chassis to lower to any desired extent. In a dump type truck, forward propulsion of the axle as aforesaid also elevates the forward end of the hinged container to thus dump its contents.
