Abstract: An electrically-operated control valve includes a rotor rotatably mounted to a first position connecting a fluid inlet port to a fluid outlet port, or a second position disconnecting the fluid inlet port from the fluid outlet port; a battery-operated electrical rotary motor for rotating the rotor; and limit switches for deenergizing the electrical motor when the rotor arrives in either the first or second positions. The electrical motor is coupled to the rotor by a speed-reducing, torque-increasing transmission such that very little electrical power is required to operate the motor, thereby enabling the control valve to be used as a remotely-controlled pilot valve for controlling a water irrigation system.
Abstract: A dispensing device particularly useful for dispensing nutritional liquids includes an electrolytic cell having electrodes and an electrolyte capable of generating a gas upon the energization of the electrodes, which gas causes the dispensing of the liquid according to the rate of generation of the gas. The container for the liquid to be dispensed may be a disposable unit including the electrolytic cell, and a non-disposable electrical control circuit may be provided for controlling the rate of energization of the electrodes. The dispensing unit may also include an outer container adapted to receive a bag containing the liquid to be dispensed, the generated gas being applied between the outer container and the pliable bag.
Abstract: An automatic irrigation device for plants which is automatically activated in correlation with the evapotranspiration needs of the plants comprises an open-top fluid evaporation pan containing the irrigating fluids, the fluids being capable of evaporating from the pan, thereby reducing its weight. A fluid conduit attached to a fluid inlet port conducts the fluids to the plants and the pan while a valve, interposed between the inlet port and the conduit and operatively connected to the pan, controls the conduction of the fluids to the pan and the plants. A counter-force member exerts a force on the pan in a direction opposite to that of the force of gravity. When the pan holds more than a first amount of fluid the valve closes and the device enters the evaporating stage. When the pan holds less than a second, lesser amount of fluid the valve opens and the device enters the irrigating stage. The device can be used to automatically irrigate a large number of plants simultaneously.

Abstract: A modular unit for a shelving system includes a pair of tube connectors each made up of half-sections together having an outer transverse dimension slightly less than the inner transverse dimension of a tube to be connected thereto, a threaded fastener threaded through an opening in one half-section and abutting the other half-section to force apart the two half-sections and thereby to firmly clamp them to a tube, and a tie rod joining a half-section of one of the tube connectors to a half-section of the other tube connector.
Abstract: A supporting member for supporting steel reinforcing bars before casting concrete thereover when making steel-reinforced concrete panels includes an elongated strip of sheet material folded into a U-shape to include a pair of substantially parallel legs at one side of the supporting member joined together by a bent integral juncture at the opposite side of the supporting member. The bent integral juncture is formed with a plurality of axially-spaced slots extending into the legs but terminating short of their bottom edges for receiving and supporting the bars transversely across the legs. Also described are a method of making such a supporting member, and a steel-reinforcement concrete panel including a plurality of such supporting members.
Abstract: A processor unit connectable between a computer and a keyboard unit stores a plurality of programs for operating the processor unit according to either a Transparent Mode wherein stored data inputted from the keyboard via a keyboard I/O port in the processor unit is transmitted to the computer unit, or according to one of a plurality of Special Handling Modes, and is controlled to select either the Transparent Mode or one of the Special Handling Modes.
Abstract: A water delivery assembly for attachment to a pressurized water supply pipe particularly useful for supplying drinking water to poultry, includes a housing having an elongated flow passageway between its inlet and outlet restricting the water flow through the outlet, and thereby permitting the assembly to be used with water supply pipes supplying water at a relatively high pressure.
Abstract: A drip irrigation emitter includes a plurality of baffles defining a labyrinth in which the baffles form clearances of different heights with respect to one of the housing walls, and in which either the housing wall or the baffles are displaced to open or close the clearances sequentially, thereby varying the resistance of the labyrinth to the flow of fluid therethrough in response to variations in the pressure of the fluid at the housing inlet.
Abstract: An oral anti-halitosis preparation adapted to desorb microorganisms and to absorb materials causing halitosis, includes as an active ingredient a synthetic oil, preferably one containing the ester of an alcholol and an aliphatic acid of at least six carbon atoms. Particularly good results were obtained when the synthetic oil is caprylic triglyceride, capric triglyceride, or mixtures thereof.

Abstract: A facial mask for use in effecting toning of a wearer's facial muscles includes two spaced layers of flexible sheet material secured together along their outer margins, and a quantity of freely movable particles of a filling material in the space between the two layers. When the mask is to be worn, suction is applied to the space between the two layers in order to effectively rigidify the mask according to the configuration of the wearer's face. The mask is pressed against the wearer's facial muscles by pressurizing an expansible chamber engageable with the back of the wearer's head, and/or by pressurizing a chamber formed by the flexible sheet layer wall and a front rigid wall.
