Abstract: A feed dispensing hopper of the type adapted to travel along the length of a battery cage arrangement to dispense feed into feed troughs extending along the battery cage arrangement which includes at least a pair of inclined wall portions converging to a channel portion to which feed is funneled by gravity. An auger device is provided in the bottom of the channel and is adapted to convey feed out through feed discharge outlets into the troughs. An agitating mechanism is provided to break up the feed that is funneled into the channel and a canopy or hood is disposed above the agitator to divert feed to opposite sides of the agitator and thus prevent packing of feed all around the agitator.

Abstract: Electrical connectors and assembly thereof comprising both male and female connectors formed from spring metal material. The assembly is particularly adaptable for use in automatically establishing electrical contact between the terminal of a self-propelled mobile unit and a fixed terminal. The female connector is formed with a constricted throat defined by first and second portions extending from secured ends to the constricted throat. The first and second portions continue from the throat diverging outwardly therefrom to define a pair of lip elements which facilitate entrance of a male connector by guiding the male connector in forcibly expanding the throat. The female connector member by reason of its spring characteristic grips the male connector to ensure an effective contact. At least one of the male or female connectors are of sufficient breadth to compensate for slight misalignment therebetween.

Abstract: A molded egg carton having a windowed cover and a cellular tray for the reception of eggs in which the windowed cover includes downposts and the tray includes up posts and in which the downposts have an offset male portion and the up posts are formed with a recess in their uppermost portion adapted to receive the offset lowermost tip of the offset male portion.

Abstract: A system for economically controlling feed of livestock to effect maximum consumption of all feed ingredients supplied to livestock comprising cage structure for confining livestock in a plurality of separate groups, separate feed troughs on the cage structure for each of the groups of livestock, and individual travelling feed dispensing hoppers for dispensing feed into the separate feed troughs. The system also includes a control mechanism for periodically effecting travel and return of the feed hoppers to dispense feed into the troughs numerous times in the course of each day. Each of the feed dispensing hoppers includes feed dispensing mechanism for causing feed to be dispensed therefrom into the troughs associated therewith. The feed dispensing mechanisms in the hopper for one group of livestock is of such capacity as to dispense all the feed that the group of livestock can eat during the course of each day with such feed being dispensed in small quantities numerous times each day.

Abstract: In a liquid dispensing pump of the deformable diaphragm type, the diaphragm includes an encircling marginal flange which is clamped between the pump housing members to function as a sealing gasket, with integral portions of the flange extending across the inlet and discharge passages leading to and from the pump chamber to function as flap type intake and outlet valves having their free edges defined by apertures in the flange through which the liquid may pass when the valves are unseated.

Abstract: A dispensing pump for application to a product container includes an elongated housing having a recess in a sidewall thereof and a flexible bulbous diaphragm seated over the recess for a trigger-type actuation as the housing is gripped in the manner of a handle. A variable volume pump chamber is defined by the diaphragm together with the recess, and an inlet passage is provided in the housing through which the product passes from the container into the recess. The diaphragm has an annular inner skirt for closing the inlet passage in response to axial deformation of the diaphragm, as well as intermediate and outer annular skirts. The intermediate skirt has a lower free edge portion normally covering a discharge port in the housing which communicates with the pump housing, and the outer skirt has a lower free edge portion normally covering a vent port in the housing which communicates with the atmosphere.

Abstract: A resiliently deformable diaphragm having a central domed portion surrounded by a marginal flange, has its flange clamped between opposing members of the pump housing whereby the central domed portion of the housing co-operates with one of the members to define a variable volume pump chamber. The convex side of the dome is received within a central opening in the other member and normally seats over and closes a vent port within said opening. An actuating lever fulcrumed on the housing has an arm movable upwardly through the said opening to deforming engagement with the diaphragm dome to alternately compress and to permit expansion of the dome.

Abstract: Apparatus and method for forming deckle-free edges and windows in molded fiber products such as cartons, trays and the like, said apparatus comprising a forming mold equipped with non-porous block-out ridge and/or patch members to define the periphery and/or windows in the finished product. The apparatus includes a mating press mold for cooperation with the forming mold with passageways therein through which jets of fluid such as air and/or steam may be supplied from a high pressure source to control deckle accumulated on the forming mold.

Abstract: A method of controlling feed ingredients and quantity consumed by livestock including the steps of confining the livestock in an area, segregating the livestock into two or more groups, providing each of the segregated groups of livestock with its own individual feed receptacle, dispensing accurately measured uniform quantities of feed into each receptacle at numerous intervals each day. In the case of poultry, for example, groups of five chickens each may be confined in a cage with a feed receptacle that is on the order of 15 inches in length provided therefor. Feed may be dispensed into each receptacle on the order of about 4 to 20 times each day. For groups of five chickens fed 16 times a day, for example, the quantity of feed dispensed into each receptacle at each feeding interval may be about one ounce per 15 inches or five chickens.
