Abstract: 1,140,444. Gas blast switches. ALLMANNA SVENSKA ELEKTRISKA A.B. 31 May, 1966 [1 June, 1965], No. 24165/66. Heading H1N. A gas blast switch (not shown) is controlled by a valve 11, 12 at high potential operated through an insulating rod 7 by an operating means at earth potential, the rod 7 being maintained in tension by the force of compressed gas in a supporting insulator column 4 upon pistons 8, 9 at the top and bottom of the rod. The combined area of piston 9 and valve member 12 is greater than the area of piston 8 so that with the space 14 vented there is a resultant force downwards to keep valve 12 closed. To open, the switch space 14 is filled with the compressed air; since piston 8 is of greater area than valve member 12 the rod 7 moves upwards opening valve 12 to pass compressed air from reservoir 1 through conduit 2 to the operating mechanism (not shown). The switch and operating mechanism may be inside tank 1. In a modification (Fig. 2, not shown) rod (7) is coupled to the valves (11, 12) by a lever (18); the relative sizes of piston (8) and valve (12) can then be different. In another modification (Fig. 3, not shown) the rod (7) operates a valve (19) which vents conduit (2) to open the switch. The space 14 may be normally filled with compressed air the rod 7 being held down by a permanent magnet (23) (Fig. 4, not shown) which may be demagnetized by a coil or have its flux shunted to release the armature (22) to open the contacts. Several series connected switches may be operated simultaneously by a linkage (24, 25) (Fig. 5, not shown) coupling together the lower ends of rods 7. The operating rod may be directly connected to the blast valve (not shown).

Title: Improvements in the sorting of small articles

Abstract: 672,999. Sorting photo-electrically. OKOLICSANYI, F., and GUNSON, (SEEDS) Ltd., R. W. Oct. 16, 1950 [Sept. 27, 1949], No. 24747/49. Class 40 (iii). Articles such as seeds falling through the discharge from a point at high voltage are deflected by the electric " wind " the intensity or position of which is controlled photoelectrically in response to the colour of an article. As shown, an electric wind passes between a point 14 at high potential and an earthed plate 16 through which seeds fall one at a time from a tray 10. Light from a source 12 is reflected from each individual seed 11 to a photo-cell 13 which controls the strength of the magnetizing current of magnets 17. According to their colour seeds either fall and are deflected by the " wind " or magnets 17 move the " wind " to one side so that the seed falls vertically. In a further arrangement, Fig. 1 (not shown), the photo-cell controls the potential of needle 14. Both arrangements may be used. The invention is stated to be applicable to the channel sorting arrangements described in Specifications 652,782 and 670,960. Specifications 617,276 and 642,284 also are referred to.

Title: Gyromagnetic resonance method and apparatus
IPC: G01R33/44
Filed: 1955-08-29
Abstract: 789,100. Electric tests. VARIAN ASSOCIATES, and BLOCH, F. Aug. 29, 1955 (Sept. 7, 1954], No. 24761/55. Class 37. In a method of determining the composition of matter, in which double or multiple lines in a gyromagnetic resonance spectrum produced by two groups of atomic nuclei which are spin-spin coupled are to be changed to one or more resonance lines of the nuclei of interest a varying magnetic field at the Larmor frequency of the second group is applied to the material, the field strength being sufficient to produce rapid transition between Zeeman levels of the nuclei of the second group thus disturbing the spinspin coupling between the two groups of nuclei. As shown, the material under investigation is inserted within the receiver coil 1 in the probe. The probe is positioned within the polarizing field produced by a magnet 2. Radio-frequency sources 14 and 3 provide the Larmor frequencies of the primary and secondary nuclei as is described below and a sweep generator 5 provides a low-frequency voltage to sweep coils 6 to modulate the polarizing field and thus cause the resonance region of the nuclei to be repeatedly swept through. The low frequency is also transmitted to the horizontal deflection plates of an oscilloscope 7 to synchronize the oscilloscope with the modulated polarizing field. Radiofrequency sources 14 and 3 feed tuned circuits each of which comprises the transmitter coil 4. The frequency of source 14 is the Larmor frequency of the secondary nuclei and is sufficiently strong to maintain rapid transition of the nuclei between polarization in one direction and then another. Thus the interfering effect of the spin-spin coupling averages to zero and coil 1 picks up the signals induced by the principal nuclei. This signal is fed to a pre-amplifier 8, R.F. amplifier 9, demodulator 11 and D.C. amplifier 12 and is then fed to the vertical deflection plates of the oscilloscope 2 and a graphic recorder 13. Fig. 4 shows the oscilloscope output from NABH4 in D20 the multiple peak being due to the spin-spin coupling of the boron nuclei. When the frequency generated by source 14 is applied the curve of Fig. 5 results, a single resonant peak being produced. In the arrangement of Fig. 3 (not shown) in which the Larmor frequency of the interfering nuclei is due to that of the primary nuclei the output of a single oscillator is modulated to produce a side band, the main frequency being used to destroy the spin-spin coupling and the side band to produce the Larmor frequency of the principal nuclei. The D.C. polarizing field may have the modulating frequency applied to it to produce the side band. The frequency for destroying the spin-spin coupling may be applied to a separate coil or a single coil may act for both transmitter frequencies and as a pick-up coil.

The second layer may comprise Si 3 N 4  with small amounts of SiO or SiO 2 . The Si may also be deposited on the second layer, and the thermal oxidation continued until the SiO 2  formed in the recess is substantially coplanar with the thermally formed SiO 2  on the second layer. The method is said to reduce the poor definition of thermally grown recessed silicon oxide layers, known as "bird's beak", which may result from using a composite SiO 2  and Si 3 N 4  etching mask.
