Title: Liquid level sensor
Inventor: Gary Haffenden
IPC: G01F25/00
Filed: 2017-11-10
Abstract: A condensate level sensor and a method of controlling a condensate pump of an air conditioning unit are disclosed, wherein: a sensor module 400 is provided having a first sensing element 410 configured to generate a low liquid level detection signal, a second sensing element 430 positioned above the first sensing element and configured to generate a top liquid level detection signal, and a level sensing element 420 positioned between the first and second sensing elements and configured to generate a variable liquid level signal; a microprocessor is provided configured to receive the low liquid level detection signal, the top liquid level detection signal and the variable liquid level signal, and to control a condensate pump. The variable liquid level signal is stored as a low liquid level reference value in a non-volatile memory upon receipt of the low liquid level detection signal. An error value is calculated as the difference between the variable liquid level signal and the low liquid level reference value. The operating speed of the condensate pump is determined based on the error value. The automatic calibration process removes the need for prior manual calibration of the liquid level sensor. The value of the liquid level signal may also be stored as a top liquid level reference value upon receipt of the top liquid level detection signal. The pump may be operated at maximum speed in response to a top liquid level detection signal. The air conditioning unit may be shut down in response to a high liquid level detection signal generated by a third level sensing element 440.

Title: Vertical bearing device
Inventor: KWANGIK NA
IPC: H02K5/167
Filed: 2016-05-24
Abstract: In this vertical bearing device, a pressure difference occurs in the lubricating oil in an oil circulation chamber 55 as a result of the difference in the centrifugal force, the shear force, or the flow speed when an annular section 33 of a thrust collar 21 rotates together with a rotating shaft member 12. The lubricating oil in the oil circulation chamber 55 is thus guided from the inner circumferential side of the annular section 33 toward the outer circumferential side via a circulation hole 71 passing through the annular section 33. The flow of the lubricating oil guided by the circulation hole 71 forms a lubricating oil flow from a lower oil chamber 47 toward an upper oil chamber 46 via the oil circulation chamber 55. As a result, the rotation of the thrust collar 21 causes lubricating oil that is stored in the lower oil chamber 47 to circulate toward the upper oil chamber 46 via the oil circulation chamber 55

Patent GB-2589878-A (GB)
Title: A control system
Inventor: ANDREW PATRICK GATT
IPC: F04B49/06
Filed: 2019-12-10
Abstract: A direct current (DC) electric pump 2 is controlled using pulse width modulation (PWM). The speed of the pump 2 is increased by increasing the ratio of the pulse width to a target ratio over a time interval t that is not dependent on the target ratio. The rate of acceleration is thus related to the target duty ratio / pump speed. The method may be used for an intermittently operated pump such as for mobile window cleaning apparatus. Because the instantaneous current drawn during acceleration is proportional to the target duty ratio, the control apparatus can quickly determine whether a threshold current is exceeded, indicating that flow has been blocked e.g. by a control valve. It is thus possible to prevent unnecessary acceleration of the pump which would waste energy and pressurise the fluid above the desired level.
