Abstract: A slotted drain includes a drain pipe having an elongated narrow slot extending lengthwise along its top surface.  A lower grate is rigidly secured to the elongated slot and is formed by a pair of bearing plates connected to one another by a series of spacer plates and connected to the edges of the elongated slot.  The lower grate is connected to an upper grate initially in an adjustable manner such that the height and angle of the upper grate may be adjusted with respect to the lower grate and the drain pipe.  The height of the upper grate with respect to the drain pipe is dependent upon the intended depth at which the drain pipe will be situated and the angle of the upper grate may, for example, correspond to the drainage slope at which the drain pipe will be set.  Once the upper grate has been adjusted to the desired height and angle, the upper grate is rigidly secured to the lower grate.  In a first preferred embodiment the lower grate telescopically receives the upper grate and in a second preferred embodiment the upper and lower grates are connected to each other by a pair of intermediate bearing plates.

Abstract: Supplied with a transmitted signal defined by sequence signal vectors each successive pair of which has an equal predetermined phase variation, a demodulator quadrature-demodulates a transmitted signal into a demodulated signal with reference to a standard signal of a standard frequency.  The demodulated signal is defined by a sequence of demodulated vectors.  An A/D section samples the demodulated vectors at a predetermined sampling rate to quantize the demodulated vectors into quantized vectors.  A signal processor constructs a composite vector from a predetermined number of the quantized vectors.  The signal processor calculates a phase difference between the composite vector and a predetermined vector to detect a frequency error between the standard frequency and a carrier frequency of the transmitted signal.

Abstract: A method and apparatus for determining liquid flow through a system including a container from which liquid is pumped out by one or more pumps, the pumping rate for all combinations of pumps being known and stored in a memory. When pumping is off, the liquid surface rises from a lower to an upper limit level. When the surface reaches the upper limit level, the pumping phase begins. When the surface reaches the lower level, the pumping is stopped and the cycle is repeated. If only one pump is required, the inflow rates prior to and just after the pump cycle are averaged. This average flow rate is multiplied by the pump time and added to the totalizer. Then the container volume is also added, following which the outflow rate (pump rate) is calculated by using the previously established average inflow rate (total volume divided by pumptime plus the average inflow rate). This value can be stored in the addressable memory.  If a plurality of pumps is required to make the liquid level drop, the liquid volume pumped during the pumping phase is calculated from information in the memory to determine the stored volume pumping rate for the particular operating pumps, and multiplying such stored rate by the duration of the pumping phase.  The result is then added to the totalizer.
