Abstract: ABSTRACT OF THE DISCLOSURE      A refrigerator including two compartments, one of which is maintained at a temperature above freezing for the storage of fresh foods and the other of which is maintained at a temperature below freezing for storage of frozen foods is cooled by air circulated over an evaporator disposed outside the compartments. The evaporator comprises a metal plate having a cooling element mounted thereon in heat exchange relationship. The evaporator is positioned in the cabinet in such a manner that the cooling element is disposed in a first passage and air is circulated over the cooling element and thence in proportioned amounts to the aforementioned compartments. To reduce the amount of frost collectong on the cooling element a second passage is provided in the refrigerator cabinet adjacent the opposite side of the plate from that on which the cooling element is mounted. Moist air returning from the fresh food compartment is caused to circulate through this second passage in contact with the aforementioned plate so that a substantial amount of the moisture in this air deposits on the plate as frost before the air reaches the first passage and the cooling element. The plate is spaced from the rear inner wall of the refrigerator to form the second passage between the plate and the inner wall of the refrigerator. The warm air circulating through the second passage, which is disposed adjacent a substantial portion of the rear inner wall of the refrigerator, reduces heat leakage from the exterior of the refrigerator to the interior of the refrigerator.

Abstract: Abstract of the Disclosure A dynamic one finger chording system with memory is connected in parallel relationship to the d.c. keying lines connecting a select number of keys of the manual to a standard keyer circuit of an electronic organ. The one finger chording system scans each keying line until a line with a d.c. level voltage signal corresponding to a manually depressed key is detected.  An identification of the detected line is used as the address to a read only memory.  In response to the address, the read only memory provides a preselected d.c. level output signal which through appropriate output circuits drives respective keying lines.  Thus one keying line has a d.c. level signal due to the manual depression of a key and a predetermined number of keying lines have a d.c. level signal due to the output signal from the one finger chording read only memory.  The same keyer circuit that is used during normal playing now provides a chord output signal.  When the key is released by the instrument player, the one finger chording system begins to scan the keying lines for the next key depressed.  If a new key is depressed without releasing the previously depressed key, the one finger chording system removes itself from the respective keying line of the prev-iously depressed key before beginning the scan for the new keying line with a d.c. level signal.  Furthermore, upon depression of a key the system receives a load pulse of finite duration which momentarily disables the scanning and clears the one finger read only memory output so that when the scanning is resumed for the new d.c. level signal it is not confused by the previous d.c. level signal output from the read only memory.  The one finger chording system has a memory mode actuatable by the instrument player and which electrically sustains the selected one finger chord after the instru-ment player releases the depressed key and until a new key is depressed or the memory feature deactivated.
