Title: Rechargeing control circuit for storage heaters - is compatible with differing climatic zones and has two tarrif charging system
IPC: H05B1/02
Filed: 1975-04-16
Abstract: An electronic control system is used for domestic storage heater systems. It provides a recharge facility during both off-peak and normal tarrif hours. The circuitry is intended to allow flexibility of use across differing climatic zones and to minimize installation costs.

Title: Heat fusing interfitting thermoplastic parts - by realtive rotation
IPC: F16L47/02
Filed: 1975-06-16
Abstract: Two interfitting components, one of which has a bore into which the other one interference fits, are joined by relatively rotating them, forwarding one into the other until the desired position is reached and stopping the rotation. The rotation causes the contacting surfaces of the components to melt, the melted region solidifying into a bond upon cooling. The invention is of use in applying collars to plastics plumbing piping, which collars form compression joint abutments. Such as collar can be applied by clamping the piping against rotation and pushing the collar over the piping to its desired position using a rotating collar gripping chuck having a projecting pilot member to guide it. Speeds of at least 2000 revs per minute are preferred and the interfitting parts of the components are an interference fit of at least 0.002 inches.
