Abstract: A lever for hand operation of the brakes and clutch from the handlebars of a cycle, wherein said lever is of a configuration for avoiding engagement with the fingers of the hand when the brakes or clutch members are actuated by depressing of the lever against the handlebars. The lever is particularly designed and constructed for ease of use during actuation of the brakes or clutch, but provides a sufficient clearance between the lever itself and the forefinger of the hand in the depressed position of the lever for precluding pinching or squeezing of the finger against the handlebars, thus improving the operating efficiency of the cycle. .Iadd.

Abstract: A vehicle having a hydraulic power brake system and a hydraulic power steering system, each having its own pump may utilize the power steering system pump as an emergency back up pump for the power brake system should the pump for the power brake system fail. The fluid under pressure in the accumulator for the power brake system will act upon failure of the power brake pump to initiate the switch over to the power steering pump.

Abstract: Method and apparatus for excavating and removing a settled body of discrete mineral solids (e.g., a tailings pond from a mining operation) by procedures which progress downwardly from the surface of the body. High pressure streams of liquid are traversed along a path in a pulping zone lowermost in first region of the body. The liquid forms a pumpable slurry with the mineral solids in the zone, and the slurry is then pumped from the zone leaving an undercut cavity sufficient to cause collapse of the overburden of solids. The collapsed overburden is then formed into additional pumpable slurry which is removed by pumping. Successive stages of excavation are carried out by moving the streams of liquid downwardly to a second region where the foregoing steps are repeated. In the apparatus a caisson is disposed vertically in the body and stabilized by means of a plurality of circumferentially positioned pilings.

Abstract: An automatic control system for high pressure blower applications prevents surging under variable supply flow rate requirements and achieves maximum efficiency of operation. The supply flow rate establishes the set point of a proportional plus reset controller, the latter receiving a feedback signal corresponding to the static discharge pressure of the supply blower and responding thereto for controlling the output of the supply blower. A return blower is controlled either through a characterizer relay in proportion to the control of the supply blower to maintain a fixed precalibrated relationship between supply and return flow rates or by a further proportional plus reset controller responsive to the supply flow rate, for establishing the set point thereof, and to the return flow rate, as a feedback signal thereto, for controlling the output of the return blower.

Abstract: Improved circuitry for increasing the sensitivity of an electron-capture ionization detector includes a closed-loop feedback circuit which varies the frequency of pulses which are applied to the detector. The circuit responds to greater concentrations of predetermined compounds such as gases by increasing the pulse repetition frequency and responds to lower concentrations by decreasing the pulse repetition frequency, always tending to keep the current flowing in the detector circuit near a constant preset value. The pulse frequency will then vary directly with the concentration of sampled compound in the detector, and simple frequency-to-voltage conversion devices can be used to signal such concentrations. .Iadd.

Abstract: In integrated circuit devices which have insulating coatings with portions of different thickness bounded by relatively high steps and deposited metal conductors on the coatings, yield losses often result from breaks in the metal conductors at the steps. By shaping the insulator step with an offset wherever a metal crossing is required, the probability of such breaks is reduced.

Abstract: An inflation system for sonobuoys and the like is disclosed in which lithium hydride in finely divided form is cast upon the surface of water ingested into a bag carried by the sonobuoy as the sonobuoy descends in the water. A spring loaded pumping system is actuated when the sonobuoy and bag are immersed in the water, with the extension of the spring also causing the ejection of the lithium hydride from a canister within the bag. The casting of the finely divided lithium hydride onto the surface of the water provides for extremely rapid gas generation such that quickly descending sonobuoys may be rapidly returned to the sea surface. Righting of the buoy is accomplished by the suspension of batteries and sonar apparatus beneath the bag through a snorkel so that the snorkel is extended and the bag righted upon immersion. The snorkel tube provides for a predetermined pressure head as well as for sealing of the buoy bag when the buoy is tilted due to wave action.
