Abstract: There is provided an alarm, which includes a mounting base, and means for securing the mounting base to an item whose movement is to be signalled by the alarm. A magnetic reed switch constitutes a first element, and a magnet constitutes a second element. One of these elements is mounted on a pivotal member capable of pivoting with respect to the mounting base, while the other of the elements is capable of retaining a given position with respect to the mounting base.

Abstract: There is provided a regulator for wall thermostats. The regulator is operated by a timer, and provides a warm air stream upwardly beneath a thermostat to cause the thermostat to lower the house temperature between specific hours, such as at night, and cuts off the warm air stream for the remainder of the day. A housing defines an air passage which has manual means for restricting it to a greater or lesser degree. Illumination and heating means are provided within the housing which simultaneously heats the air to promote convective flow upwardly, and illuminates the manual means.
