  • Electric supply for ion therapy
    Patent number: 4292968
    Abstract: A power supply provides direct current to electrodes attached to a patient. The positive electrode is at least partially silver and releases silver ions as a result of the electric current. Silver ions have known bactericidal properties and may be used to treat infected living tissue. Tissue may, however, be damaged by voltages in excess of 1.1 volts. Accordingly, the power supply has two modes. Under normal conditions the power supply has a constant current output. If the voltage between the electrodes reaches a reference voltage of not more than 1.1 volt, the output is changed to a constant voltage mode, abruptly limiting the output voltage. A mode indicator may be incorporated in the supply.

  • AC Generator system having stabilized sensitivity for sensing the presence or absence of a conductive object
    Patent number: 4291280
    Abstract: A conductive object detector having an eddy current killed oscillator, wherein the oscillator output is stabilized by means of a proportional plus integral controller. The controller proportional gain is set low and the integral time long, hence a conductive object near the oscillator will "kill" it, whereas the controller will minimize the effect of temperature or aging on the oscillator output.

  • Quick opening manhole cover assembly
    Patent number: 4279356
    Abstract: A quick opening manhole cover including a clamping flange (16) which captures the ears (48) of a locking ring (46) upon rotation of the locking ring with respect to a manhole cover (40).

  • Sludge siphon collector with de-gasing header
    Patent number: 4276165
    Abstract: A siphon system for a sewage settling tank or the like has a baffle fixed to the inside top surface of the collection header to prevent gas bubbles evolved from the sludge from entering the sludge inlet. An opening through the top of the header just upstream from this baffle allows the gases collected against the baffle to vent from the header and into the settling tank.

  • Fluid resistor
    Patent number: 4275767
    Abstract: A fluid resistor with a fluid tight structure including two planar members having a surface of each contacting in close proximity. One of the planar members has a laminated structure including a substrate and at least one thin layer of substantially uniform thickness formed on the substrate. A groove extends through the layer. The groove and the surface of the other planar member define a capilliary passageway of substantially constant depth for restricted fluid flow.

  • Beach for the scum trough of a sewage settling tank or the like
    Patent number: 4268394
    Abstract: A beach for the scum trough of a sewage settling tank or the like is biased to an upright position by a weighted member or the like so as to prevent the flow of liquid over the beach and into the scum trough. The construction of the beach allows it to be rotated against this bias to a second position below the level of liquid in the settling tank, so as to permit scum and other floating materials accumulated adjacent the beach to flow over the beach and into the scum trough.

  • Interpolating digital data processing apparatus for correlation-type flow measurement
    Patent number: 4254470
    Abstract: Interpolating apparatus is provided for more accurately determining the peak position of a function, particularly a cross-correlation function derived from two related flow signals fed to an overloading counter correlation flowmeter, whereby the peak position is indicated by a set of signals corresponding to quantized values of a parameter and the apparatus interpolates the peak position from selected signals of the set. The preferred method of operation comprises computing for each of the signals an average of the quantized values of the parameter corresponding to that signal, and summing a predetermined number of these average values to obtain an indication of an interpolated value of the peak position. Various output circuits are provided for flowmeter applications to produce an output which is proportional to flow rate.
