Abstract: 710,432. Regenerative heat-exchangers. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. Sept. 21, 1951 [Oct. 6, 1950], No. 22136/51. Class 64(1) A rotary regenerative heat-exchanger is provided with sealing members, pivotally mounted on one of the main parts (stator or rotor) of the apparatus and in sealing contact with the other of said main parts of the apparatus (rotor or stator respectively) said sealing members each having a concave surface the axis of curvature of which coincides with the pivotal axis of the sealing member so that the resultant of gas pressure acting on the sealing member will pass through said pivotal axis thereby making the applied sealing pressure independant of the direction of prevailing gas pressure, a flange extending from that main part of the apparatus on which the sealing member is pivoted and being in sealing contact with the concave surface of the sealing member. The invention is applicable to radial or circumferential seals and the sealing pressure may be applied by springs or weights and in some cases by the weight of the sealing member itself. The drawing shows an arrangement of circumferential seals between the matrix rotor 10 and the end plates 30 of a stationary casing surrounding . the rotor. Each sealing plate' 26 is arcuate in cross-section and is carried on an arm 24 pivoted at one end of the rotor at 22. The seals at the upper end of the rotor are maintained in sealing contact with the adjacent end plate 30 by weights 28 or the equivalent and at the lower end of the rotor sealing contact is effected by .the weight of the seal itself, a counterweight. 36 being provided if necessary. Flanges 12 are secured at each end of the rotor and extend outwardly to make sealing contact with the concave surface of the sealing plates 26, the axis of curvature of each sealing plate passing through its pivot point 22 so that the seal remains unaffected by the resultant of gas pressure acting thereon.

Title: Improvements relating to slip indicators
IPC: G01P3/58
Filed: 1951-09-21
Abstract: 704,191. Electric indicating systems. RECORD ELECTRICAL CO., Ltd., and LOMAX, S. Sept. 19, 1952 [Sept. 21, 1951], No. 22159/51. Class 40 (1). A ratio meter for indicating the percentage slip between two rotating members driving tacho-generators G1, G2, has a current coil energized according to the difference output voltage of the two generators, and a pressure coil energized by one or both of the outputs whereby the meter indicates the speed of one member as a percentage of the speed of the other or the slip as a percentage of the average speed. In Fig. 1 the speed of generator G2 is indicated as a percentage of that of G1, the pressure coil A being energized by generator G1 and the current coil B being series connected with the two opposing generator outputs. Resistors R1, R2 equalize the loads on the two generators. A centre-zero type meter is used so that it will indicate the sense of the slip. Fig. 2 shows the pressure coil A connected via equal resistors R1, R2 across both generators so that the slip relative to the average speed of the generators is indicated. In another arrangement the speed of G1 is compared with a fraction of that of G2 by connecting the range determining resistor R3 to a tapping or a potentiometer connected across G2, Fig. 3 (not shown). The resistor R2 may be adjustable, Fig. 4 (not shown), to compensate for changes in the generated voltages. For a precise indication of zero-slip a lamp L, Fig. 5, is connected, via isolating condensers C, across the generator outputs to indicate the beats between the ripple outputs of the generators. These beats may be timed by a stop watch for small values of slip and disappear at zero slip. The range may be extended, Fig. 6, by a relay S connected across the generators which shortsout resistors R1b, R2b, R3b, when the average speeds drops below a predetermined level. Additional relay stages to extend the range further may be used.

Abstract: 1,062,453. Deflecting light. INTERNATIONAL BUSINESS MACHINES CORPORATION May 29, 1964 [June 5, 1963], No. 22287/64. Heading H4F. Apparatus for varying the position and direction of a beam of light comprises a biaxial crystal 12 and means for producing a beam of light which is plane polarized in a selectable one of a plurality of different planes, eg.an electro-optical device 21, and a quarter-wave plate 24, the incident plane polarized beam 26 being directed along one of the optic axes inside the biaxial crystal so that the phenomenon of internal conical refraction takes place, the position of maximum intensity of the output beam on the cone circle 12b depending on the direction of polarization of incident beam 26. Light from source 15 first passes through polarizer 16 and the resulting plane polarized beam 25 is transformed into a circular, elliptical or plane polarized light beam 28 in electro-optic device 21 depending on the voltage V applied across the electro-optic device by way of transparent or semi-transparent electrodes 22 and 23. Quarterwave plate 24 is so orientated as to transform the circular polarized light beam 28 into a plane-polarized light beam 26, the direction of polarization of which depends on the voltage V. The output beam from cone circle 12b, the position of maximum intensity of which depends on voltage V, is then focused by means of a cylindrical lens 17 on to a curved mirror 13, the resulting light beam 30 having a direction with a predetermined deviation or orientation between 30a and 30b for use in some form of readout apparatus. Instead of using mirror 13 crystal 12 may be replaced by a crystal 31, Fig. 6, having a prismatic shape along its rear face 32. Crystal 31 achieves the same phenomenon of internal conical refraction and the same intensity distribution as crystal 12 of Fig. 1 but in addition deflects the output beam 33 in a particular orientation or direction between the rays indicated at 33a and 33b. The arrangements of Figs. 1 and 6 provide a cos<SP>2</SP> intensity distribution of the conically refracted-light of the crystals 12 and 31, and to improve the beam resolution, the intensity distribution is improved to a cos<SP>4</SP> distribution by means of additional quarter-wave plate 43, electro-optical device 44 and analyser 40 arranged as shown in Fig. 7. The material of the electro-optical device may comprise potassium dihydrogen phosphate, ammonium dihydrogen phosphate or potassium deuterium phosphate and the material of biaxial crystal 12 may comprise naphthalene, anthracene or aragonite. Kerr cells, magneto-optical means and strain or stress optical structures may be used instead of the electro-optical device.

Abstract: 659,685. Measuring the amplitude of pulse. DECCA RECORD CO., Ltd., TANNER, S. R., and WIERSMA, R. A. Aug. 29, 1949, No. 22423. [Class 37] [Also in Group XL (c)] In a radar apparatus test device (see Group XL (c)), the amplitude of received pulse signals of radio or intermediate frequency having a substantially constant pulse repetition rate is measured and indicated on a meter 24. The pulses, see Fig. 2A, fed in at A are rectified by diode 17 whose load comprises a small condenser 18, which charges to almost peak value for each pulse, and a leak resistor 19. The signal at B thus developed, see Fig. 2B, is applied to the control grid of valve 20 to produce positive voltage peaks in the anode circuit at C as shown at 2C. These positive peaks cause diode 22 to conduct for a short period, flattening the peaks as shown, and placing a negative charge on the plate of condenser 21 connected to the diode. Resistor 23 and meter 24 provide a leakage path for the negative charge and the time constant is made much greater than the period between successive pulses so that the waveform at the point D is as shown at 2D and the meter deflection is proportional to the shaded area. This area is approximately proportional to the peak value of the signal pulses and the meter may be calibrated for such values.
