Title: Thermoplastics tube welder
IPC: B29C65/78
Filed: 1970-04-03
Abstract: Filled, open ended thermoplastics tubes are indexed round and raised onto a conveyor where they are clamped to leave their ends free for welding by means of a pipe system coupled to a gas source and with ports pointing towards the tubes from both sides of the conveyor. The pipes connect to hot and cold sources thus feeding in cold air behind the weld and press down point to cool and stabilise the joined ends. The hot air used for the welding is cut off immediately the conveyor stops, thus preventing any scorching of the weld. The air supply switch is linked to the conveyor switch for simultaneous cut-out and assured quality control.

Title: Lining metal tubes with plastics - by fluidised bed method, with very accurate metering of plastics powder used
Inventor: SCHEIBER WERNER DR
IPC: B05D7/22
Filed: 1973-05-26
Abstract: Plastics powder (e.g. nylon-11) to be metered is cycloned in a fluidised bed by passing a gas therethrough, and the powder is sucked out, with the aid of gas, through an injector arranged in the fluidised bed. The powder is then blown into a main current which flows towards the metal surface to be lined, the pressure to which the fluidised bed is subjected being greater than that in the main gas stream. Very accurate metering and dosing of finely divided plastics powder into rapidly flowing gas streams is possible so that even extremely small amts. of plastics powder may be uniformly dosed-in over relatively long periods of time.

Title: Plant-watering device with controlled outflow - consists of an outer pipe with apertures and flexible coaxial tube with apertures
Inventor: ALLPORT DAVIES
IPC: A01G25/06
Filed: 1974-06-11
Abstract: The outer surface of the inner tube touches the inner surface of the outer pipe and both surfaces, or either one, are roughened or have for example fabric inserted between the two to form cavities inbetween. Outflow apertures are situated along the length of both inner and outer tubes, and are positioned at a certain distance from each other. The water flows through the inner tube through the holes along the cavities inbetween, and out of the hole in the outer pipe. The inside tube may be joined to the outer pipe by a lengthwise seam. The arrangement causes a gradual seep of water into the soil rather than excessive and wasteful flow.
