Title: Plastic net material - manufactured by extrusion through reciprocating dies
IPC: B29C48/10
Filed: 1972-10-20
Abstract: A thermoplastic polymer such as polypropylene is melt extruded under pressure through a series of die orifices to form 'net-like' structures. One set of dies is arranged either in a circular pattern or in a side-by-side relationship and the plastic extruded from them. Separate plastic streams are extruded independently from other dies so that these second streams cross the first set in a plane normal to it. The separate streams are allowed to set at the points of contact so giving the net-like pattern. To further facilitate the operation at least one of the dies reciprocates vertically.

Title: Two power supply circuit for infra-red lamp - has series rectifier diode bridged by shorting switch
IPC: F21V23/00
Filed: 1974-01-10
Abstract: The supply circuit, for an infra red lamp, has a diode (4) in series with the infra red lamp (2) and bridged by a switch. With the switch open, the a.c. supply is rectified by the diode before reaching the lamp, and is therefore reduced in power; but with the switch closed the diode is short circuited and the unrectified a.c. reaches the lamp, resulting in maximum power being supplied. The advantage of the circuit lies in its simplicity. Several IR lamps may be coupled in parallel and supplied via the same diode/switch circuit, or they can be supplied each from a separate such circuit.

Title: Reciprocating mandrel for forming sockets on plastic pipe - by deflecting hard elastic collar to create an undercut socket profile
IPC: B29C57/04
Filed: 1974-03-13
Abstract: Mandrel is used for producing a tulip or undercut socket on the end of a thermoplastic pipe by aligning the pipe end with one end of a hydraulic chamber enclosing two coaxial pistons. The larger piston has a conical nose which produces a tubular dilation of the pipe end. Once the full depth of the basic socket has been formed, the inner piston advances through the outer mandrel so that radially projecting shoes on the inner piston deflect a hard but elastic collar mounted behind the nose of the larger piston to produce further local radial dilation of the pipe socket profile. Reversing the sequence of the piston motions allows the flexible collar to retract within the socket and retire through the relatively small socket mouth as shown.
