Abstract: The method relates to manufacturing contact spring sockets with a plurality of radially inward bowed contact springs clamped at one end in an approximately cylindrical socket body, formed by a thin-walled deformable sleeve. After introduction of the straight contact springs into the socket body from one socket end, they are made fast by deformation of the socket material and their free ends are brought into supporting abutment on an annulus. This is associated with a mandrel for assisting assembly, which passes through it and which is during manufacture introduced co-axially into the socket body and finally withdrawn from it. Subsequently the mandrel together with the annulus is introduced into the socket body. The contact springs are then, by applying axial pressure on their ends, converted into a shape bowed into the interior of the socket until they abut the mandrel.

The straight contact springs, formed by sections of a contact spring wire, are introduced into the socket body and made fast at their front ends to a central head (10) at the front end of a line connector (2) by deformation of the socket material. The free ends of the contact springs (9) are brought into supporting abutment on an annulus (5) at the pin insertion end.

Abstract: To avoid venting of a deburring chamber and associated equipment after charge of the chamber with an explosive mixture if a spark plug (3a) has failed to ignite the mixture, a glow ignition block (4) is located in the path of gas communication between a mixing block (3) in which the spark plug is retained, and a glow plug (8) is located to have its glow portion exposed to the combustible gas mixture, preferably in a bypass (9) to a main gas path. A thermal element (12) monitors whether, upon application of an ignition pulse to the spark plug (3a), ignition has occurred by sensing a sharp temperature pulse; upon failure to sense such a temperature pulse, the glow plug is energized for ignition of the combustible mixture thereby. The spark plug may be of the vehicular internal combustion engine type; and the glow plug may, for example, be similar to "pre-glow" plugs used in vehicular-type Diesel engines.
