Abstract: 602,979. Phase changing. STANDARD TELEPHONES & CABLES, Ltd., and CLEAVER, R. F. Nov. 14, 1945, No. 30460. [Class 38 (ii)] [Also in Groups XXXVI and XXXVIII] A phase-changing device comprises a rotary potential divider which is in the form of a plurality of straight equal and uniform resistance elements arranged to form a regular polygon, e.g. a bridge square A, B, C, D and a single contact arm 5 or a pair of contact arms 5, 6 adapted to rotate in continuous contact with the polygon and about the central axis thereof in such manner as to travel along all the elements in turn. The supply system feeding the polygon should be symmetrically earthed, e.g. effectively as in the circuit of Fig. 1 by potentiometers 13, 17 each of which has an adjustable contact at earth potential to balance the two output circuits 10, 14 of the two phase generator supplying equal current to the opposite bridge corners A, B and C, D, respectively. Under these conditions a balanced output voltage may be drawn from the arms 5, 6 which in this case are non- resistive, at corresponding points of their traverse, the phase angle and the magnitude of this voltage varying according to the chosen angle of setting # of the arms 5, 6 in a clockwise direction from the starting points A, B respectively. The arm 6 may be omitted and a voltage to earth obtained from the arm 5. In a modification, Fig. 4, the device comprises a polygon of M-sides, the corners of which A, B, &c. are connected respectively to the N-phase conductors of an N-phase supply, and a contact arm 32 in the form of a resistance element connected to earth at the point which passes through the centre O of the polygon and provided with a fixed inner point Q from which may be derived a voltage to earth varying in phase angle as # of the arm 32, but of constant magnitude. The resistance element may extend to opposite sides of the polygon and have two fixed points thereon from which may be obtained a balanced output voltage. In a further modification, Fig. 11 (not shown), a polygon in the form of an equilateral triangle possessing a non-resistive contact arm and appropriately connected to a 3-phase system is coupled with a similar auxiliary polygon, having non- resistive elements and a high resistance contact arm which in its rotation is in continuous contact with an inner circular conductor. The two contact arms are ganged for synchronous rotation and the arrangement produces an output voltage to earth of adjustable phase angle equivalently to that of Fig. 4. A further similar auxiliary polygon may be provided in which case a balanced output voltage may be obtained across the two circular conductors. The device is further adaptable according to another arrangement, Fig. 12 (not shown), for the production of voltages proportional to cos # and sin #.

Abstract: 1,168,971. Digital measurement of distance. M. S. COOK. 5 July, 1967 [8 July, 1966], No. 30679/66. Heading G4H. [Also in Divisions G2, H1 and H4] Light of variable frequency is transmitted to an interferometer, and the changes in the interference fringes are counted as the frequency is varied over a known range. In the form of Fig. 1 the distance between two points A, B is determined by positioning a mirror 2a, 2b at each of the points to form a Fabry- Perot etalon arrangement, which is illuminated to produce an interference fringe pattern by a radiation source 1, the frequency of which can be changed from a first value to a second value in a continuous sweep, the number of changes in the fringe pattern being counted during the frequency change. The radiation source comprises a laser 1a directing a beam on to a crystal 1b e.g. of lithium metaniobate which is contained in a temperature controlled chamber 1 A heater 1d is connected to a control source 1e to change the temperature of the crystal. Part of the laser beam is changed to a different frequency by the crystal. The laser frequency is blocked by a filter 1f leaving only the crystal frequency which is changed by changing the temperature of operation. As it changes, the interference pattern at mirror 2b also changes, the number of changes being counted by a photo-detector 3 and counter 4. The value in the counter is proportional to the distance apart of the mirrors. In a modification the variable frequency radiation source is a laser having a coil placed round the tube which, when it is energized, causes a splitting of the light into two components having opposite circular polarization, one of which is blocked. The other has a single frequency which is changed by changing the field of the coil.

Filed: 1962-08-13
Abstract: 1,060,151. Packaging. UNION CARBIDE CORPORATION. Aug. 13, 1963 [Aug. 13, 1962], No. 30954/62. Heading B8C. A method of packaging comprises placing an article in a pouch of flexible plastics film drawing a vacuum through the pouch opening to bring the film into tight engagement with the article, and closing and sealing the opening at a point adjacent to the article while maintaining the vacuum. Mounted on a frame 10 are an evacuating assembly 14 with a reciprocable evacuating plunger 30, a closing and cutting assembly 16 movable horizontally at right angles to the movement of the plunger, a support rail 64 and a support platform 82 movable about a hinge 84. An elastic plastics bag containing an article is fed on to the platform 82 and the neck of the bag is placed over a protruding barrel 26 of the evacuating assembly housing the plunger 30. The neck of the bag is held manually on the barrel 26 while the plunger 30 is advanced into the bag. If the article being packaged is hollow, e.g. a chicken, the plunger also advances into the cavity of the article. Air is withdrawn through radial openings 38 (Fig. 3, not shown). The plunger 30 is retracted, the withdrawing of air being continued until the openings 38 are closed by a flange 27 of the barrel 26. The platform 82 is then pivoted downwards and the package is left suspended over a support rail 64, the mouth still being held over the barrel 26. The weight of the article tensions the film between the article and the end of the barrel so that a metal clip or other closure can be applied. The closing and cutting assembly 16 now advances until aligned with the barrel 26, a strip 81 (Fig. 6) guiding the film over a knife sheath 74, the force from the tensioned film depressing a knife blade 72 below the surface of an anvil 73. A spring 80 returns the sheath and blade to the cutting position so that when the assembly 16 is retracted after application of a clip by known means (not detailed), the neck of the package is pulled between the blade 72 and the anvil 73, severing it just outside the clip. Since the mouth of the film bag remains firmly gripped against the barrel 26 during the sealing, a vacuum is maintained, thus preventing the re-entry of air into the package. The apparatus is pneumatically operated, means being provided to prevent advance of the closing and cutting devices prior to withdrawal of the plungers 30. The barrel 26 is rotatable by a hand lever 46 which also operates valves to carry out the various operations.
Patent GB-1541533-A (GB)
Title: Gas turbine assemblies
IPC: F01D5/08
Filed: 1977-07-22
Abstract: The gas turbine installation is supplied with cooling air (7) which is removed from an intermediate stage (4) of the compressor (2) and is passed to the turbine (3) within the rotor (1). The removal of the cooling air (7) from the intermediate stage (4) of the compressor (2) takes place via a guiding means (8) such that, when it emerges from the guide means (8), it flows approximately tangentially and has a velocity relative to the rotating system which is approximately equal to the peripheral velocity of the boundary walls but is directed in the opposite direction to the latter. The cooling air (7) can thereby be introduced into the rotor (1) with a low absolute velocity and, as a result, the pressure losses are small. In this gas turbine installation, cooling air (7) can be removed from a low-order intermediate stage (4) of the compressor (2) with a low outlay on construction and with a minimum pressure loss, having a correspondingly low temperature, and fed to the turbine blades to be cooled close to the axis of the rotor (1). In addition to an improved cooling efficiency, this reduces the power consumption of the compressor (2) and correspondingly increases the effective output of the gas turbine installation. <IMAGE>
