An ash scoop which remains out of the water during most of its operation. The ash scoop has a retaining and a nonretaining configuration. It moves along a track downward into the pit while poised in its nonretaining configuration. Once in the pit, it moves to its retaining position to grab debris within the pit. It then moves back out of the pit along the track until it reverts to its nonretaining configuration to dump the ashes dragged out of the pit.

The disclosure relates to fence battens and clips and improved methods of attaching a fence wire. A variety of battens are described characterised by having slots into which a wire may be inserted. A variety of interacting clips which can be used to subsequently fasten the wire with respect to the batten are also described. The battens and clips are especially suitable for electric fences.

Settler, notably for liquid treatment installations, consisting of a settling tank fed with liquid from a feed channel and a spillway, the settler including a system for distributing the liquid consisting of a plurality of gauged openings formed respectively in partitions of liquid inlet chambers fed from the spillway, in such a way that each opening receives a specified fraction of the throughput of the liquid, the openings being staggered in at least two horizontal rows.

A loft ladder which can be pivotally and slidably mounted to loft opening has counterbalancing means including a resiliently biased pivotal arm, connected to the loft ladder by a link member pivotally connected between the pivotal arm and the loft ladder to allow the ladder to turn about is pivotal connection to the loft opening over at least a limited extend. The arm has a two-stage resilient biasing spring offering a greater resilient force over part of the range of movement of the arm. A hand...

Improvements for an incinerator system including double reburn tunnels, an excitor within a reburn tunnel, a choker for closing off part of a reburn tunnel, a grate near the incinerator's inlet to permit the drying and initial combustion of refuse, an ash scoop which remains out of the water during most of its operation. The use of dual reburn tunnels, along with a damper that permits the closure of at least one of them, permits the efficient and environmentally acceptable utilization of the mai...

A novel planter which facilitates watering of a plant over extended periods, and also facilitates transplanting of the plant with little or no shock.

A portable flower pot for house plants which is essentially open at the bottom, the bottom of which is in the form of a grid or a screen, said bottom prior to adding the growing medium being at least 35% open and preferably at least 75% open, said grid or screen having openings at least 1/36" and smaller than about 1/8" in the largest dimensions.

A Kenya hive is modified to accept on top thereof at one end portion of the Kenya hive a Langstroth hive. Better wintering of bees in colder climates is thus achieved while retaining the known advantages of the Kenya hive. Modified forward brood frames and frame spacers enable the mounting of the Langstroth hive with stability on this portion of the Kenya hive. Modifications of the rear honey frames and top bars improve the efficiency of the Kenya hive and reduce its manufacturing cost. Other im...
