Title: Suspension-type poultry drinking fountain
Inventor: SHOMER YAIR
IPC: A01K39/022
Filed: 1983-05-13
Abstract: A suspended-type poultry drinking fountain comprises a hanger assembly including a stem adapted to be supported in a vertical position by suspension from its upper end, and a bowl supported by the hanger assembly and containing a water trough for receiving water to be made available for drinking by the poultry, The hanger assembly includes a horizontal, annular, resilient gasket circumscribing the stem, and a valve housing having a water inlet, a water outlet, and a hollow conduit member therebetween and disposed to overly the annular gasket.

Title: Flow-metered pumping with load compensation system and method
Inventor: LIVINGSTON JAMES W
IPC: D06F33/37
Filed: 1994-09-26
Abstract: The present invention is an improved flow-metered pumping system using an air-backed diaphragm pump with load compensation. A variable motor speed controller is used to compensate for flow rate reduction caused by pressure effects. When the output pressure on the pump increases to a point where the load on the pump motor exceeds a specified threshold, the motor speed controller increases the speed of the motor to compensate for pressure induced diaphragm distortion losses and to achieve a substantially constant flow rate across a range of pump output pressures.

Title: Electrochemical cell having controlled electrolyte flow
Inventor: HOLMES JOHN PETER
IPC: C25B11/00
Filed: 1984-09-21
Granted: 1987-09-09
Abstract: An electrochemical cell has an annular flow passage for electrolyte solution. The cell is designed such that, in an intermediate zone, the passage is of constant cross-section (to achieve high electrolytic activity) and, in end zones, the passage progressively increases in cross-section to a maximum value (to lower the current density in regions in which unwanted deposition of salts may preferentially occur). The cross-sectional shape of the passage along its length also assists in reducing turbulence in the flow thereby reducing the rate of deposition of salts. Owing to the low rate of deposition, it is possible to maintain the electrodes relatively clean by current reversal at relatively infrequent intervals. That enables the cell to be used for longer periods between cleaning operations.

Title: Method of producing electrical heating elements and electrical heating elements so produced
Inventor: BOARDMAN JEFFREY
IPC: C23C4/08
Filed: 1988-06-27
Granted: 1991-05-08
Abstract: A method of forming an electrical heating element in the form of an electrically non-conductive supporting body onto which an electrically resistive material is deposited, the method comprising the steps of preparing a dry metal powder of irregularly shaped metal particles of widely varying sizes, in the range 20-150 microns, roughening the surface of a supporting body onto which a heating element is to be formed, pre-heating said surface of the supporting body to a temperature within the range of 150-250 DEG C and flame spraying the dry metal powder onto said heated surface of the supporting body in a plurality of passes over the supporting body. The effective resistivity of the flame sprayed deposit is predetermined by adjusting the amount of oxidation on the surfaces of the metallic particles sprayed onto the supporting body. The amount of oxidation on the surfaces of the flame sprayed particles, and hence the resistivity of the sprayed deposit, can be varied by selecting the size range of the particles used, within said range of 20-150 microns. Alternatively the amount of oxidation on the surfaces of the flame sprayed particles can be varied by blending selected alloys into the powder to by sprayed such as to adjust the quantity of conductive oxides present on the sprayed particles.
