Title: Controlling article demoulding
Inventor: KENNEDY GERARD
IPC: B29C39/00
Filed: 1987-06-23
Abstract: Plastics in a granular or powder form is introduced into a mould at a moulding station 2 to 5 or 9 to 11 from which a moulded plastics article is delivered by a respective transfer device 7 onto a conveyor 1 or 1a. The delivery of plastics articles onto the conveyors is controlled by photoelectric units 15, 16, 17 and optical proximity switches 20 to prevent a plastics article from one station colliding with an article from another station. When a plastics article passes between one of the transmitters 15a, 16a, 17a and its associated receiver 15b, 16b, 17b an output signal is sent to the control system which prevents the transfer mechanism 7 from dropping an article onto the conveyor until a preset time, which is typically 10 seconds, has elapsed to allow the plastics article already on the conveyor to clear the station. <IMAGE>

Title: Ring seal
Inventor: ORGAN ALAN HENRY
IPC: F28F3/10
Filed: 1992-03-07
Abstract: A ring seal comprises a ring 1 of elastomeric material protected by a layer of PTFE. The outer diameters of the ring are trimmed by a cutting tool to expose a peripheral sealing contact ring 8 between two supportive shoulders 9 and 10 of PTFE. The exposed elastomeric material 8 provides an efficient sealing contact whilst the less resilient PTFE shoulders 9 and 10 prevent distortion of the elastomeric material.
