Abstract: A low voltage spot light for use as substitute for a mains voltage PAR38 reflector lamp which comprises a chamber for LED clusters with reflectors and an enclosure for an electronic power supply to step down the incoming mains voltage. The LED clusters are mounted in the central area of the heat sink within the chamber and are accessible via a removable window. The LED chamber is weatherproof ventilated to prevent condensation. The spotlight is designed for outdoor use in conjunction with the PAR38 style weather proof lamp holder but can be operated indoors from any standard E 27 lamp holder.

Abstract: An apparatus monitors discharge processes in a conductor of a medium-voltage system or a high-voltage system. The apparatus contains at least one transformer which is suitable for detecting a current flowing in the conductor. The at least one transformer is connected to a device for monitoring the discharge process. In order to be able to monitor even very short discharge processes in an energy-saving manner, a release and at least one storage circuit are arranged between the transformer and the monitoring device. When a threshold current flowing in the conductor is exceeded, the release switches the monitoring device from a passive mode that is not suitable for monitoring into an active mode that is suitable for monitoring. The storage circuit stores the discharge current to be monitored and/or recorded by the monitoring device.

Abstract: A low-voltage spotlight for use in substitution for a mains voltage PAR38 spotlight includes a casing which houses a removable low-voltage halogen lamp and metal reflector and apparatus for stepping down the incoming mains voltage. A lampholder for the removable halogen lamp is mounted on a metal casing which acts as a heat sink and also as a conductor of heat to the outer surface of the casing for dissipation. The spotlight is completely sealed for outdoor use in conjunction with a weatherproof PAR38 lampholder.

Abstract: A lawn comber or thatcher comprising a drum carrying a multiplicity of rows of radially extending tines extending from the surface of the drum, each row extending in a generally angular or helical path along the drum and being spaced such that at least one tine is always in contact with the ground to provide a driving force for the thatcher, each tine having a torsion or helical spring portion at a position adjacent the inner most end of each tine.
