Abstract: Devices for stiffening automotive vehicle coil springs comprise spacers positionable between one or more adjacent convolutions of the springs. The spacers offer no or very minimal resistance to limited compressions of the springs, but an increased resistance to increased compressions. They do not interfere with the standard manufactured height of the springs or vehicle, and under normal driving conditions the vehicle rides smoothly on its suspension. However, under severe conditions, causing sufficient compressions of the springs, the spacers stiffen the reaction of the springs for increased roadability, handling and safety.

Abstract: Apparatus for separating folded two-on cartons is characterized by a carton supply station for advancing cartons seriatim to a separating station. At the separating station, opposite edges of each carton are gripped and first moved away from each other to pull the two-on carton apart into two separate cartons, and then moved toward each other to bring the separated cartons back together. The separated cartons are then conveyed out of the separating station while the supply station simultaneously advances the next successive two-on carton to the separating station.

Abstract: A sampler for communicating with the interior of a vessel containing dry granular or powder materials extracts a sample of the material and conveys it to a point of collection. The sampler includes a tubular probe having an inlet opening toward an inner end and the probe is reciprocable into and out of the vessel for a flow of material into the inlet and through the probe to an outlet from the probe. To assist the material flow a jet of fluid is introduced into the inner end of the probe to aspirate material into the inlet opening and convey it through the probe, and when the probe is retracted from the vessel the jet purges the same of residual material. One or more valves are provided to control the jet of fluid and enable a momentary flow of fluid outwardly of the inlet opening when the probe is retracted to clear the opening of any material lodged therein.
