The present invention provides a technique using current sensing to control the pressure at constant level without the direct sensing of the pressure. This technique will help to reduce dependency solely on switch or sensor and their non linearity and other associated problems such as the non-repetitive behavior, being affected by EMI etc. The technique includes using a pump controller featuring one or more modules configured to respond to one or more input signals containing information about current provided from a pump; and configured to provide one or more output signals containing information to control the pump to operate at a substantially constant pressure without the direct sensing of pump pressure. The one or more modules control the operation of the pump based at least partly on a table of characteristics related to voltage and current that is calibrated for each pump.

Apparatus is provided featuring a switch-mode power supply (SMPS) having a power circuit component in combination with a SMPS controller. The power circuit component may be configured to provide power to a pump that provides fluid from a container to some other device, including an appliance. The SMPS controller may be configured to receive signaling containing information about at least one control parameter selected from a group including a pressure at an outlet of the pump, a fluid level in the container and the temperature of a motor of the pump, and also may be configured to shut off the power provided to the pump based at least partly on the signaling received so that the power circuit component substantially does not draw power and heat up when the pump is shut off.

A method and apparatus are provided for coupling a pump head (1) and a motor housing (4) of a pump together so that a rotational positioning ring (2) of the pump head (1) frictionally engages a snap ring (5) of the motor housing (4) so as to allow for 360° rotation of the pump head (1) in relation to the motor housing (4), where the orientation of the pump head (1) and the motor housing (4) are adjustable in relation to one another so as to allow an end user to set the orientation of the pump in any configuration. The positioning ring (2) has a plurality of members separated by slots for radially flexing when the rotational positioning ring (2) is axially coupled over the snap ring (5) of the motor housing (4). Each of the plurality of members has a rim so as to form a raised edge for frictionally engaging a corresponding raised edge of the snap ring (5) of the motor housing (4).

The present invention provides a method for replacing seals in recreational vehicles gate valves without removing valve housing from plumbing. The method for replacing blade seals in a gate valve features coupling a valve housing of the gate valve to suitable plumbing, the valve housing having a removable blade seal cartridge slidably arranged and latched therein in order to receive a movable blade of a drive unit of the valve gate to control the flow of the medium through the valve gate and to prevent the medium from entering the drive unit; and unlatching the removable blade seal cartridge from the valve housing so as to enable replacement of the blade seal cartridge without having to remove the valve housing from the suitable plumbing.

A radiation curing apparatus comprises a plurality of solid state radiation sources to generate radiation that cures a first material. The solid state radiation sources can be disposed in an array pattern. Optical concentrators, arranged in a corresponding array pattern, receive radiation from corresponding solid state radiation sources. The concentrated radiation is received by a plurality of optical waveguides, also arranged in a corresponding array pattern. Each optical waveguide includes a first end to receive the radiation and a second end to output the radiation. The curing apparatus can be utilized for continuous substrate, sheet, piece part, spot curing, and/or 3D radiation-cure processes.

A continuous gravity flow apparatus for heating and/or drying of particulate material is vertically disposed and is provided with an inlet at the top and an outlet at the bottom. The apparatus includes a flow passage for the particulate material which is defined between an outer housing and an inner housing. Each of the outer and inner housing defines perforated wall sections allowing for the flow of hot gas through the wall of one housing, into contact with the particulate material, and then out through the wall of the other housing. Manifolds are associated with the outer and inner housings to provide for uniform flow of the gas through the material. The perforated wall sections are positioned and designed to enhance particle-to-particle movement of the material to thereby avoid particle sticking and bridging problems.
