Abstract: With reference to Figure 3, the sloping roof 250 of a building 10 incorporates inner and outer juxtaposed metal panels, 15, 16 spaced from each other to define passageways 20 which serve as heat exchangers. A closed-loop water circulation system 18 connects the passageway 20 with low, medium and high grade heat store chambers 21, 23, 25 disposed within the building foundation structure 13.      The water circulation system 18 employs sub-systems 22, 29 and 31 which comprise, respectively, primary, secondary and tertiary sub-systems. The heat store chamber 21 comprises a portion of the primary circulation sub-system 22 whereby water is re-circulated through the panel passageways 20 so as to be raised in temperature by solar heat. In addition to the heat store chamber 21, the primary sub-system 22 comprises a heat pump unit 27. The secondary water circulation sub-system 29 conveys water in a closed loop which, in addition to the heat store chamber 23, comprises the passageways 20 and the heat pump unit 27. The tertiary water sub-system 31 comprises the heat store chamber 25, radiators 19, underfloor heat exchanger coils 35 and a heat exchanger coil 37 incorporated in a hot water cylinder 39. Heat from water flowing in the primary sub-system 22 is given up to the heat store chamber 21 and also to the heat pump unit 27. Heat from water flowing in the secondary sub-system 29 is given up to the heat store chamber 23, as well as to the heat pump unit 27. A controller 40 is operable to provide controlled transfer of heat between the sub-systems 22, 29, 31,

Title: Fall indicator for use with fall arresting devices
Inventor: WOLNER JAMES THOMAS
IPC: A62B35/00
Filed: 1993-02-15
Granted: 1995-10-03
Abstract: A fall indicating device including an indicating portion that is normally retained within the body of the fall indicator. Upon the exertion of sufficient force upon the fall indicator, as, for example, from the forces generated during fall arrest, a restraining member within the body of the fall indicator, such as a shear pin or a series of disk springs, releases the indicating portion, alerting the user that the fall restraining device has been subjected to fall arrest forces. In the case of fall indicator using a shear pin, the indicator may require replacement after being subjected to fall arrest forces. However, a fall indicator using a spring or series of disk springs may be reset after usewithout needing to be replaced.       The fall indicating device may also be integrally attached to a connecting member such as a snap hook. When integrally connected to a snap hook, the snap hook, using the free end of the fall indicator, may be attached to the line or cable issuing from a safety device such as a self retracting lifeline.
