Title: Interferometers and apparatus for use therewith
Inventor: DYSON JAMES
IPC: G02B27/10
Filed: 1964-07-01
Abstract: 1,076,835. Interferometer. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 28, 1965 [July 1, 1964], No. 27224/64. Heading G2J. [Also in Division G1] An interferometer for producing interference between two beams plane-polarized at right-angles to each other comprises a diffraction grating which produces two separated secondary beams of substantially equal intensity from the recombined interfering beams, the secondary beams being passed through an analyser means so that they display periodical variations in intensity when the path difference in the interferometer is varied. The recombined beam may be produced by a Michelson interferometer Fig. 1 (not shown) by passing light from a source (1) which has been collimated by a lens (2) into a split cube (5) having a polarizing filter (6) on its diagonal interface; the two beams (3) and (4) polarized at right angles to each other, are passed through quarter wave plates (9) and (10) respectively, and reflected back through the plates and split cube to give a recombined interfering beam 24. As shown in Fig. 2, the beam 24 is passed through a diffraction grating 16 consisting of transparent strips which are separated by spaces equal to their width giving two first order diffraction beams 17, 18 which are focused by a lens 19 through an analyser 21 on to photo-cells 22, 23; the beam 18 also passes through a quarter wave plate 20 so that the variations in the intensity of the two beams 17 and 18 are in phase quadrature.

Abstract: 1,269,757. Boric acid. EAGLE-PICHER INDUSTRIES Inc. 5 June, 1970 [6 June, 1969], No. 27339/70. Heading C1A. Boric acid is produced by reacting a dimethyl ether-boron trifluoride complex with an inorganic lithium compound having a hydroxyl, carbonate or sulphate anion in the presence of water. Preferred lithium compounds are LiOH, Li 2 CO 3  and Li 2 SO 4 . The dimethyl ether-boron trifluoride complex which may be prepared by passing BF 3  gas through dimethyl ether, is preferably added to an aqueous solution or slurry of the lithium compound, and the mixture refluxed until all the complex is converted to boric acid, and the resulting dimethyl ether has been evaporated off. The residual mixture, comprising lithium fluoride and an aqueous boric acid then has its pH adjusted by the addition of Ba(OH] 2  to between 6À0 and 7À0 if necessary, due to the use of lithium sulphate to ensure precipitation of the lithium fluoride and any barium sulphate; the solution is filtered and the precipitate is washed thoroughly and the filtrate plus wash liquor is passed through an ion exchange resin to remove any residual LiF. The resulting solution is evaporated to saturation and cooled to 0 C. to recover boric acid crystals.

Abstract: 432,395. Making gaines. SCHAEFER, K., 15, Eberhardstrasse, Dortmund, Germany. Sept. 27, 1934, No. 27741. [Class 83 (ii)] Exploder casings or gaines for shells for ordnance are produced by drawing sheet iron or steel in the cold to form a tube closed at one end and thickened at the other by excluding this end from at least one drawing operation, and then upsetting the thickened end to form a rim on which the thread and key-engaging surfaces are formed. A disc of sheet metal is cupped, and then further drawn to the form of a long sleeve S, Fig. 4, the upper portion being unaffected by these drawing steps so that a thickening is obtained at the mouth. The thickened mouth is then upset to produce a thickened rim R, Fig. 5, in which a screwthread, and surfaces for engagement by a key are formed. An annealing operation may be interposed. A coating, for example of cadmium or brass, may be applied to the gaine, and the surface may be subjected to the process known as parkerization, wherein a thin layer of iron phosphate is obtained by treating with a phosphate solution. Steels having specified contents of manganese and silicon may be employed.

Abstract: 1488961 Performance learning apparatus GOLDMARK COMMUNICATIONS CORP 1 July 1975 [2 July 1974] 27760/75 Headings G5X and G5G For learning a performance of, for instance, a piece of music or a play, there is provided a magnetic tape record of the performance with one part omitted with space on the tape for recording a students attempt to provide the missing part, the tape having recorded at intervals along it control pulses which correspond to stop notations marked on the students score or script and arranged to define separate learning sections of the performance. In Fig. 1 the four tracks 18À1 to 18À4 of the tape record carry respectively the performance with the part omitted, a professional example of the omitted part, the control pulses, and the students performance. Any one or more of these tracks can be replaced via suitable switching by an amplifier A. The control pulses may actually be recordings of words signifying the segments of a musical score (Fig. 3, shown) but which appear when replayed rapidly, as high frequency pulses. The magnetic head reading the student track 18À4 may be switched to a recording amplifier A to record from microphone 50. If during his performance the student makes an error and wishes to return to the beginning of the current segment of the performance he may depress a push button switch 78 which energizes a motor 80, for rapid rewind, through a transistor 92. The transistor remains conductive until a pulse is read from the control track when motor 80 is denergized and the tape continues to play in the normal manner. Repeated depression of the switch causes the tape to be stepped back several segments. The action of the control pulse is delayed so that the tape always winds back just beyond the beginning of the segments and the pulse is used to close a switch 24À3 such that the recorded word forming the control pulse is heard at the beginning of the segment after rewinding. The control track 18À3 may also carry metronome pulses which are separated from the control pulses by filters 75, 79.
