Abstract: A multiple-position slide switch having a detent member operative side-wise with respect to the path of movement of the sliding contact carrier of the switch to hold the carrier in a selected position. The detent member which is formed of material, preferably such as moldable plastic, having the power of recovering its initially produced durable or static shape when a deforming force or pressure causing it to be temporarily deformed is removed, is in the form of a flat member having a pair of laterally spaced longitudinally extending flexible struts which embrace therebetween an upwardly projecting knob of the slidable carrier, the inner edges of the struts and the outer surfaces of the carrier knob being complementally shaped to provide coacting surfaces which coact upon deflection of the struts to snap the carrier into its selected position.

Abstract: A hose clamp utilizing two constricting band type hose clamps which are tied together by means of a strapping arrangement includes one clamp which surrounds the hose itself and is provided with protuberances which press into the outer surface of the hose to provide a strong gripping function which prevents the hose from moving with respect to this clamp while at the same time engaging the hose in a non-destructive manner. The hose if not grippingly interengaged with the clamp would under pressure slide out of the clamp and off of the fitting. A second hose clamp is clamped about the rigid fitting to which the hose is attached at a point beyond an enlargement in the fitting, so that this clamp cannot move past the fitting enlargement. The straps connecting the two clamps then prevent the hose from sliding off of the rigid fitting because of the restraint provided by the clamp which is secured beyond the fitting enlargement.

Abstract: A dial pulse detector apparatus accurately detects the occurrence of dial pulses in the presence of adverse line conditions resulting in severe signal distortions due to inductive effects, noise and loading by other pieces of equipment. Signals greater than two different selected threshold levels are examined for, and signals less than the lower threshold are also examined for. Signals greater than the threshold levels are counted up on a time duration basis and added in a weighting arrangement. Signals less than the lower threshold are counted on a time duration basis and are subtracted from the added signals. When the combined signal counts reach a first specified count a dial pulse break signal is recognized. Signal counting is continued and when the combined signal counts reach a second specified count a dial pulse make signal is recognized, thereby completing the detection of a dial pulse.
