Title: Apparatus for the combined utilization of used water and waste heat from waste water
IPC: E03B1/04
Filed: 1991-10-01
Granted: 1994-02-25
Abstract: The invention specifies an apparatus for the combined utilization of used water and waste heat from waste water, the apparatus comprising 2 concentric chambers 2, 6 each with a heat exchanger 5, 7, connected in series. The outer chamber 2 has a small volume. Waste water is admitted via a lye pump 11, via a riser 14 and an annular distributor line 15, into the outer chamber 2. The water flow within the chambers takes place by means of riser pipes 8, this resulting in a countercurrent principle. A second lye pump 18 pumps cooled used water from the inner chamber 6 into the flushing cistern of the WC. Located in the riser 14 are 2 changeover valves 23, 24 by means of which hot waste water from showering can be directed into the washing machine for the main washing cycle. A valve 25 with a linkage 27 and float 26 is provided in order to prevent a lack of water. The preheated fresh water is fed to the boiler, the dishwasher and the kitchen. This arrangement results in the following possible savings: 75% energy for hot-water preparation, 35% energy and 15% water for washing laundry, 25% energy for the dishwasher and 10% energy for cooking. <IMAGE>

Title: Symmetrical door lock
Inventor: MUUS FRANK
IPC: E05B63/04
Filed: 1983-12-01
Abstract: A symmetrical latch lock has a spring-loaded latch, which moves forward and back in a lock casing (2), and which is actuated by two followers (9, 10), which are symmetrically positioned around the casing's horizontal longitudinal axis. At least the one follower can be drawn to locked position, wherein it prevents the latch from moving inwards to the lock housing (2). The latch is divided into two separate movable pieces, a hammer piece (3) and a slide (4). The slide (4) can move in the hammer's (3) lengthwise direction and is fitted with a load transfer plate (6) which transfers the hammer (3) inwards into the lock housing (2)and with load transfer plates (5) which, in the same direction, are functionally connected with the followers (9, 10). The resulting symmetrical lock has a simple construction, where the followers move easily but generally in such a way that their functional position is clear to anyone using the lock.<IMAGE>
