Abstract: 1,002,295. Theft alarms. ACCUMULATORENFABRIK SONNENSCHEIN G.m.b.H. Nov. 5, 1963 [April 17, 1963], No. 43577/63. Heading G4N. A system for signalling unauthorized displacement of an article positioned on a surface comprises a circuit, enclosed within a housing disposed between the article and the surface, which includes a switch actuated by means of a magnet attached to the article. As described, a housing of ferro-magnetic material 14, Fig. 1, is disposed between a picture 10 and a wall 13 and includes two magnetically actuated switches 33, 34 normally held open by magnets 29, 22 attached to the picture and the wall, respectively. The magnets are positioned over holes in the housing and hold the housing hidden behind the picture. Movement of the picture causes a reduction in the magnetic field acting on one of the switches allowing it to close, completing the alarm circuit, Fig. 2 (not shown), which then radiates a sonic signal. The signal is picked up on microphone 53, Fig. 5, and fed via a voice scrambler 54 to actuate relay 56 which completes the alarm circuit to bell 50. Once actuated, this circuit holds in by self hold relay 60 until reset by button 58. In order to detect failure of the battery 51, a further relay 62 releases with low voltage to actuate the alarm. Instead of sonic radiation electromagnetic radiation may be used with suitable transmitters and receivers. In a modification, Fig. 4 (not shown) the magnetic switches may be normally closed, holding a relay energized to keep the alarm circuit operative. Such an arrangement will also initiate an alarm with low battery voltage in the unit 14.

A further downstream extension of the mandrel may be heated to melt and smooth the pipe interior. The downstream projecting portion of the mandrel, Fig. 6, may be provided with six longitudinally extending grooves 38 for forming internal longitudinal pipe ridges, at locations corresponding to longitudinally spaced apart projections 39 from the mould halves which define cavities extending from the pipe exterior into the ridges. The cavities may be transformed into perforations through the pipe upon cutting the ridges away by means mounted to the mandrel, to form a drainage or underground irrigation or, if the ridges are not removed, a pipe serving for the protection of electrical cables. External longitudinally extending fins 41, 42, Fig. 8, may also be moulded on the pipe, and such fins may define a square shape with transverse fins. The spaces between the fins may be filled with a filling, e.g. of foamed polyurethane, around which an exterior sheath may be extruded, Fig. 10 (not shown). A pipe 18, Fig. 3, preferably having annular fins 18<SP>1</SP>, may have an exterior plastics tubular sheath 19, either extruded or subsequently fitted, to reinforce the pipe 18 and provide thermal insulation in the spaces between the fins 18<SP>1</SP>. With a polypropylene pipe 18 and the spaces filled by polyurethane, hot water may be conveyed. The fins, Fig. 3, may extend helically and an exterior tubular sheath may define, with the fins, channels for the flow of heating or cooling medium. Alternatively such channels may be filled with insulant such as mineral or glass wool. Three start helical fins may be provided, Fig. 13 (not shown), and may comprise interconnecting three start helices of opposite hand, Fig. 14, providing resistance against both internal and external pressures. The pipes may be used as road culverts. Lengths of the pipe may be joined, Fig. 12, by a joint effected within a sleeve 50, with sealing rings 51, and such a joint may also be employed for pipes having a filling material between the fins, or a tubular outer sheath.
