Abstract: 1420798 Repairing surface crazing of foamed polystyrene sheets OWENS-ILLINOIS Inc 19 Dec 1973 [20 Dec 1972] 58764/73 Heading C3C [Also in Division F2] Crazing damage to the surface of expanded polystyrene sheet, which sheet has been formed with a solidified central region of density smaller than its surfaces, is repaired by heating the damaged surface of the sheet sufficiently to soften and fuse damaged areas of the surface, and cooling the heated surface of the sheet before the heat penetrates sufficiently into the sheet to cause expansion of blowing agent contained in the central region of the sheet. Expanded, general purpose, high density polystyrene containing residual pentane and having a crazed surface, W, may be passed over a heated roller 12 with idler roller 13 controlling the angle of wrap between W and 12, which is also controlled by cooled roller 14.

Title: Moulded thermoplastic article and method of making same

Filed: 1973-12-21
Abstract: 1456998 Moulding hollow articles N W LANE 21 Dec 1973 [8 Jan 1973] 59574/73 Heading B5A A method of rotationally casting a closed, seamless, hollow article from a cross linkable, particulate, polyolefin comprises casting the resin in a heated rotating mould to form a fused layer on the mould and, before the thus moulded part can be collapsed by the partial vacuum produced by cooling of the air inside the part, the part is rapidly cooled to a temperature below the heat distortion point of the resin so that it becomes sufficiently rigid to withstand the forces produced by the vacuum. If desired, the article may be withdrawn from the mould allowed to cool and collapse, heated up to above the heat distortion temperature of the resin so that the air inside expands and the elastic memory of the resin article to spring back to the original moulded form, and then cooled as described above to produce the rigid article. The cooling in the first method may be effected by spraying the mould, and in the second by plunging the article into water. The examples relate to the production of fishing buoys from polyethylene, although polypropylene may also be used.

Filed: 1971-12-23
Abstract: 1374457 Self-propelled sprinkler WRIGHT RAIN Ltd 21 Dec 1972 [23 Dec 1971] 60029/71 Heading AID A sprinkler on a self-propelled carriage is guided backwards and forwards past a hydrant from which it is supplied through a hose 16 wound on a drum 15 carried by the carriage and continuously driven in the hose-winding sense by a transmission including a chain drive 25 having resilient tensioning means that enable the drive to the drum to be overridden by the hose-unwinding rotation of the drum as the carriage moves away from the hydrant, thus preventing the hose from being unwound too quickly. In Fig. 1 power is provided by a reaction spinner 20 supplied from the hydrant and the carriage is guided along a furrow in which guidance wheels 30, 31 run. The wheels 12 are driven through a gear drive 27 which, when the carriage reaches the end of the furrow is reversed through a mechanical link system by the contact of one of the shoes 36, 37 with the end of the furrow or a stop. The sprinkler may be a long range nozzle 14 or a fixed or rotatable boom which may also contribute some reaction to power the carriage. In Fig. 3 (not shown) the carriage is propelled by an internal combustion engine and guided by a guidance cable. The engine drives two pumps. One pump powers the two fluid motors that drive the wheels and the other powers the fluid motor that rotates the drum carrying the hose. In response to signals on the cable a controller, through a combined electrical and fluid operable control circuit (Fig. 5 not shown) reverses the drive to the wheels at the ends of the cable and reduces the torque applied to the drum while the hose is being unwound by switching in a low pressure relief valve across the fluid motor. The carriage may automatically be kept on the correct course by stopping or reversing the drive to one wheel.
