Title: Candle filter with easy element change - having elements fixed to insert which is screwed down into housing from above giving minimum process interruption
Inventor: FRIEDRICHS DIETER ING GRAD
IPC: B01D29/15
Filed: 1978-11-11
Abstract: Candle filter has elements which can be easily changed. The element is attached to an insert which is mounted from above and which is removed by pulling out the insert.

Title: Combined heat pump and boiler - uses boiler as driver, with additional water heating coil for increased heat outputs
Inventor: MECKEL BERND DIPL PHYS
IPC: F25B30/04
Filed: 1980-05-16
Abstract: The combined heat pump and boiler circuit for providing a hot water supply has a boiler (1) also acting as a driver with a rectifier column (4) and an outlet passing vapourised refrigerant through a heat exchanger (2). Cold water passes through this heat exchanger to cool the vapours, before entering the coil (12) inside the absorber (10). The condensed refrigerant passes through an expansion valve (7) before entry into a heat exchanger (8) before return to the absorber. The boiler exhaust gases pass through a coil (20) to heat the incoming air (9) for this heat exchanger, before discharge. The rich solution from the absorber passes through a heat exchanger in counterflow with the weak solution, then through a valve (14) for discharge through a line (15) into the rectifier column. Another outlet line (16) from this valve discharges into the sump (2) of the driver. The first line (15) discharges onto a coil (17) forming a branch of the hot water supply, and is only operated when the coil is not used, for normal operation. The second line (16) only is used when the coil is used for increased heat loads.
