Title: Evacuating moulding material
IPC: B29C45/60
Filed: 1981-04-28
Abstract: When manufacturing components by means of injection moulding an elastomer material is injected in a plastic state into a mould 4, in which the transfer of the material to an elastic state by means of vulcanization is initiated. The material is removed from the mould 4 when it is stable with regard to its shape and substantially free from pores, and the required retention time in the mould for obtaining this result restricts the capacity of the injection moulding machine. In accordance with the invention the elastomer material is subjected to the influence of a negative pressure generated by a vacuum pump 30 while in a plastic state in an injection unit 6 by means of which the elastomer material is injected in the mould. Thereby, the required retention time in the mould 4 is substantially reduced. The injection unit may be used in conjunction with a series of moulds mounted on a turntable. <IMAGE>

Patent GB-2176275-A (GB)
Title: Apparatus for controlling the temperature of the circulating water in a central heating system
Inventor: SUTTON DAVID MICHAEL
IPC: F23N1/08
Filed: 1985-06-10
Abstract: The apparatus comprises a first temperature sensor 15 for providing a voltage output related to the prevailing flow water temperature, and a second temperature sensor 16 for providing a voltage output related to the prevailing outdoor air temperature. These signals are used to control the burner of a boiler 1. In this way it is possible to control the temperature of the flow water leaving the boiler and thus the return water temperature in response to changes in the outdoor air temperature. This is of advantage where the boiler is of the condensing type since the return water temperature can be reduced to a targeted minimum value which is sufficient to satisfy space heating demands yet enables the period during which the boiler is operating in the condensing mode to be extended. Details of various valve constructions and operations and of how the boiler burner is controlled, are also disclosed, together with details of the electronics of control arrangements. <IMAGE>
