Title: Improvements in Screw Rotor Machines
IPC: F04C18/16
Filed: 1967-06-06
Abstract: 1,191,312. Rotary compressors and motors. ATLAS COPCO A. B. June 6, 1967 [June 22, 1966], No. 26045/67. Heading F1F. A rotary compressor or motor of the intermeshing screw type comprises a housing 1, Fig.2, having a pair of intersecting bores 2, 3 with parallel axes in which are rotatably mounted intermeshing main and gate rotors 6, 7 respectively having helical threads 8, 9 and helical grooves 10, 11 with the wrap angle of the main rotor 6 between 330 degrees and 450 degrees so that operating as a compressor compression starts in a main rotor groove before a low pressure radial port 20 Fig. 1, of rectangular cross-section which extends substantially from end-to-end of the rotors is closed and operating as a motor the low pressure port is opened to a main rotor groove before expansion is finished. The radial low pressure port 20 and a radial high pressure port 33 communicate respectively with conduits 16, 17 whose axes are at right angles to each other and at 45 degrees to the common plane passing through the axes of the rotors 6, 7. The port 20 is formed with small axial extensions at the high and low pressure ends of the compressor respectively to avoid an undesirable building up of high pressures and a delayed opening of the inlet port. The outlet port 33 also includes a slight axial extension which prevents the formation of pockets in which undesirable high pressures occur. The greater wrap angle permits of a diameter-length ratio of rotor between 0À8 and 0À4 and a smaller lead angle which may be less than 45 degrees which permits of a bigger volume of fluid being handled and higher rotational speed of the rotors.

Title: Improvements in or relating to aircraft guiding apparatus
IPC: G05D1/06
Filed: 1946-08-30
Abstract: 647,192. Landing indicators for aircraft. SPERRY GYROSCOPE CO., Inc. Aug. 30, 1946, No. 26221. Convention date, Aug. 30, 1945. Addition to 646,702, [Group XL (c)]. [Class 4] [Also in Group XL (c)] An instrument landing system for aircraft comprises an indicator presenting simultaneously a plurality of navigational indications including indications showing the displacement of the craft from a course-line defined by an overlapping-beam radio beacon and the course that the craft should follow in order to approach the course-line smoothly. The indications are presented upon the screen of a cathode-ray tube 2 which bears a representation of an aircraft 3. The control signals for the several indications which are derived from a directional gyro 6, a gyro-horizon 8, a localizer receiver 10, and a glide-path receiver 11 are applied in succession by means of a commutating device 13 to the cathode-ray tube. The indication 5 is controlled by a signal derived from a potentiometer controlled by the directional gyro 6, and by a signal derived from a pre-set potentiometer which is so arranged that the indication is central when the craft is flying parallel to the localizer beam and is deviated to the left or right according as the craft deviates to the right or left from this direction. A scale marked on the screen of the cathode-ray tube indicates the magnitude of this deviation. The line indication 7 is controlled by a signal derived from a potentiometer controlled by the gyro horizon 8 and rises or drops according as the nose of the craft pitches below or above the horizontal plane and is further caused to pivot about its centre in accordance with the roll of the craft. A circular trace 9 is positioned in accordance with the signals derived from the receivers 10 and 11 and is displaced from the centre of the screen in accordance with the displacement of the craft from the course-line defined by the beacon. A spot 12 is positioned in accordance with signals corresponding to those used for controlling the indications 5 and 7 and is deviated from a central position in accordance with the deviation of the heading of the craft from a course parallel to the beacon course-line. The movement of the spot 12 is opposite from that of the indications 5 and 7 so that when the circle 9 is displaced from its central position and the craft attitude is altered to cause the spot 12 to come into coincidence with it, as illustrated, for example, in Fig. 4, the heading of the craft is such as to bring it asymptotically on the course-line. Specifications 496,521 and 536,090, [both in Group XL], are referred to.
