Patent GB-2195565-A (GB)
Title: Dart point sharpener and shaft roughener
Inventor: RATTLIDGE FRANK EDWIN
IPC: B24D15/08
Filed: 1986-09-13
Abstract: A body unit (a) has a central hole (b) for receiving the shaft (c) of a dart, initial insertion of the dart shaft causing its point to abut mid-way against an angled and resiliently mounted abrasive element (e) so that rotation of one relative to the other will abrade the point and gradually sharpen it. Continued rotation, whilst the shaft is further progressively inserted and gradually withdrawn, will cause the abrasive element, which is radially loaded by resilient means (f), to lift, pivot and pressurably adjust to the increasing diameter and changing contour of the shaft causing it to be totally abraded from the sharp point to the shaft's major diameter, thereby roughening the surface area which penetrates a dart board, improving its retention ability. <IMAGE>

Abstract: PCT No. PCT/GB88/00434 Sec. 371 Date Jan. 22, 1990 Sec. 102(e) Date Jan. 22, 1990 PCT Filed Jun. 2, 1988 PCT Pub. No. WO88/09740 PCT Pub. Date Dec. 15, 1988.A sewage treatment plant for use aboard ship comprises a vacuum assisted fresh water flush system delivering sewage to a collection tank. Sewage is collected from the collection tank in batches for treatment. The sewage first enters a settlement tank and is then transferred to an aeration tank. After aeration, treated sewage is then transferred out in batches. The batch processing overcomes the difficulties of operating a continuous flow arrangement on a moving platform where liquid can move back and forth, which presents difficulties in controlling the level of biological activity. A controlled amount of sewage transferred to the aeration tank is diluted with grey water. A sludge storage tank is provided and suspended solids probes are provided in the aeration and settlement tanks such that sludge is automatically withdrawn from these tanks to the storage tank to maintain the level of suspended solids within predetermined limits. The sludge storage tank is provided with aerators and its temperature is controlled such that aerobic digestion renders the sludge inert. Small batches of aerated liquid are drawn from the aeration tank into a chlorination tank via a separation system at controlled intervals between successive sewage batch transfers from the collection tank to the aeration tank via the settling tank prior to discharge from the plant.
