Filed:

Jun 18, 2003

Appl. No.:

10/464116

Inventors:

William Herring - Newton Grove NC, US

Assignee:

Hog Slat, Inc.

International Classification:

C02F003/02

US Classification:

210/167000, 210/202000

Abstract:

Systems and methods for treating waste water containing biological wastes such as animal waste generated in livestock-raising operations, wherein the waste water is subjected to a series of operations to separate solids from the liquid phase of the waste water and to biologically treat the waste water to break down organic components. The separated solids are stored for further treatment or conversion into useful materials. The treated liquid phase can be put to various uses. In one embodiment, the treated liquid is recycled as flush water for flushing animal waste from an animal barn, whereby little or no liquid phase escapes the system into the surrounding environment.

6/202613

Inventors:

William T. Herring - Newton Grove NC

International Classification:

A01K 0500

US Classification:

119 535

Abstract:

An animal feeder apparatus is provided with a separate pivotally supported gate on each side thereof which is generally vertically adjustable by adjustment means extending above the feed storage bin of the apparatus so as to be readily accessible at each side of the apparatus for varying the size of respective feed discharge openings below opposite side walls of the storage bin.

Appl. No.:

7/337177

Inventors:

William T. Herring - Newton Grove NC

International Classification:

B29C 3926

US Classification:

425253

Abstract:

This invention relates to an apparatus for molding slotted concrete floor sections. The apparatus forms the concrete floor sections in an inverted position so as to avoid the need for hand finishing of the upper surface of the molded concrete floor sections. The apparatus comprises a base, opposing pairs of interconnected upstanding side and end walls connected to the base and a plurality of elongate spaced apart and substantially parallel ridges connected to and projecting upwardly from the base. Attached to and overlying the ridges are a plurality of elongate keystone shaped dividers removably mounted on and extending upwardly from the ridges with the upper surface being in a substantially common plane with the upper surfaces of the side and end walls. The dividers are attached to the apparatus by downwardly extending connector means which extend through holes in the ridges to a force applying means positioned below the base and operatively associated with the connecting means for supplying a downward force from below the base of the apparatus.

Appl. No.:

6/243510

Inventors:

William T. Herring - Newton Grove NC

International Classification:

A01K 1015
A01K 102

US Classification:

119 20

Abstract:

Concrete gang slats, that underlie and support thereon farrowing crates within a farrowing house, are provided with opposing elongate side openings in which elongate foraminous inserts are positioned to accommodate newborn pigs thereon in the overlying side pens of the respective farrowing crates. The foraminous inserts are constructed to facilitate the footing of newborn pigs in suckling so as to avoid abrasion of their knees while permitting their waste to readily pass through the inserts.

Inventors:

William T. Herring - Newton Grove NC

International Classification:

A01K 100
A01K 102

US Classification:

119 20

Abstract:

Slotted floor sections formed of reinforced concrete and commonly referred to as gang slats, that underlie and serve to support farrowing crates within a farrowing house, are provided with conduit means embeddedly built in the gang slats for circulation of a heated fluid through side sections of the gang slat for maintaining surfaces of the side sections in a warm condition conductive to promoting a healthy litter of newborn pigs, and wherein additional conduit means are embeddedly built in a central section of the gang slat so as to concurrently aid in maintaining surfaces of the central section in a cool condition conducive to the health of the sow.

International Classification:

A01K 102

US Classification:

119 28

Abstract:

Slotted floor sections formed of reinforced concrete and commonly referred to as gang slats, are provided for underlying and serving as a floor for pig nursery pens and wherein conduit means are embeddedly built into respective end sections of the gang slats for circulation of a heated fluid therethrough for applying warmth to the pigs for promoting the health thereof and wherein the respective end sections are accessibly located adjacent the center aisle of the nursery and attract the pigs thereto for thereby aiding in visual inspection of the pigs.
