Title: Aircraft engine failure warning system
IPC: B64C27/12
Filed: 1981-07-01
Abstract: On helicopters where two engines 10, 11 drive the rotor(s), the failure of one is compensated by an automatic increase in output of the other, except in high power demand situations.

Title: Gas pressure regulator assembly
IPC: B67D1/14
Filed: 1982-01-19
Abstract: A gas pressure regulator assembly for fitting in a system for supplying carbon dioxide to beer kegs comprises a mounting and connection block 11 which has an inlet 12 for connection to a carbon dioxide supply pipe, two outlets 18 and 19, for connection to a beer keg and to a pressure gauge respectively, a chamber 16, which is connected to the inlet 12 by a duct 13, and which contains a poppet valve 14 having an operating member 15, and an annular chamber 17 from which the outlets 18 and 19 lead and which communicates with the chamber 16 through a pressure regulator 23 which has an inlet port in the face 26 and an outlet port in the face 27. The pressure regulator 23 is preset to provide a predetermined outlet pressure and has a screw-thread 21 which is screwed into an internal screw-thread 20 in the chamber 17. The pressure regulator 23 has a handle 24 and when it is partially unscrewed from the chamber 17, it is disengaged from the valve member 15 so that the valve 14 closes and shuts off the inlet 12 from the outlets 18 and 19. Screwing in of the regulator 23 by the handle 24 causes the regulator to engage the member 15 and open the valve 14 so that carbon dioxide flows from the inlet 12 to the outlet 18 through the regulator 23. To enable the outlet pressure to be altered, the pressure regulator 23 is fully unscrewed and removed from the chamber 17 and it is then replaced by another regulator which is structurally similar, but is set to a different preset outlet pressure. <IMAGE>

The processor obtains values concerning the densities and colors of a selected area of the original image from the first electrical signal associated therewith, and compares them with reference values to produce corrections of tones and colors, which are in turn stored in a memory (40). The processor modifies the second electrical signals in accordance with the corrections to provide the recording unit with the modified signals as the image signals. <IMAGE>
