Title: Improvements in or relating to magnetic resonance techniques and apparatus
IPC: G01R33/46
Filed: 1968-09-27
Abstract: 1,214,551. Nuclear magnetic resonance  spectrometers. SPECTROSPIN A. G. Sept. 27, 1968 [Sept.27, 1967], No.46003/68. Heading G1N. [Also in Division H3] In a high resolution nuclear magnetic resonance spectrograph, a linear frequency sweep is generated by dividing the output frequency of a variable frequency oscillator by a whole number greater than one and adding an auxiliary frequency which is variable, preferably in discrete steps, for shifting the reduced sweep range in the frequency range N.M.R. is obtained. As shown in Fig. 4, a quartz oscillator 1 generates a stable base frequency fs which is mixed in a mixer 3 with the output frequency fs + S of a controllable oscillator 2 controlled by an error signal derived from comparing the output frequency S of the mixer 3 with that of a voltage to frequency converter 10 fed with a linearly variable reference voltage. The output frequency of oscillator 2 is divided in divider 13 and mixed in a mixer 15 with a frequency <SP>fs</SP>/ n  obtained from oscillator 1 and divider 14 to produce a linear frequency sweep signal of frequency <SP>s</SP>/ n . This signal is then mixed successively in ring modulators 33 and 42 with frequencies fk <SP>k</SP>/ r  and <SP>fh</SP>/ n  (small compared with fs), obtained as shown in a manner similar to that in which the frequency <SP>s</SP>/ n  is obtained, and is finally mixed with the base frequency fs in a mixer 44 to produce an output signal of frequency fs-(<SP>fh-s</SP>/ n )+<SP>k</SP>/ r fk. By choosing r> n, the individual sweep range portions can be made to overlap. For a system having a resonance stabilized magnet capable of operation at more than one field strength by selection of an appropriate stabilization frequency, the stabilization frequency may be a selectable multiple mfs of the base frequency and the output from mixer 44 may be connected to a multiplier 46 for multiplying by the selected factor m.

Abstract: 465,799. Cash registers. NATIONAL CASH REGISTER CO. Nov. 12, 1935, No. 31248. Convention date, Nov. 22, 1934. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 13, 1936.] [Class 100 (iv)] [Also in Group XIX] Web-feeding arrangements; hammer-impression arrangements.-In a case register or similar accounting machine adapted to make impressions on a voucher and an inserted slip from a single set of type wheels and by means of a single impression hammer that, during a machine operation, makes a scuccession of - printing strokes or none dependent upon the position of manually adjustable control means, the arrangement is such that, with the control means in one position, successive prints can be effected upon a voucher and a slip and, in another position, successive points can be effected upon the slip only. The invention is described as applied to a machine of the kind disclosed in Specification 441,340, wherein a lever 11 controls blocking means for a printing hammer 58 that normally makes two printing strokes with the lever in " Off " position, but is inoperative in the other positions of the lever. In the present invention, the lever 11 also controls the position of the block 88 that determines the extent to which the slip can be inserted into a guide 87, and thus the number of impressions that will be made thereon before it is fed past the printing position by the linespacing mechanism. The conne tions between the lever and block include a cam slot 24 and roller 25, levers 27, 28, 31, 322 and link 321, the arrangement being such that, with the lever 11 in " Check " position, the block is in right-hand position and the slip is fed out of the machine after the first impression to enable the second impression to be made on the voucher. On the other hand, with the lever 11 in " Slip " position, the slip will receive both impressions and the voucher strip none. The position of the block and the number of imprints that are to be effected on the slip are indicated by numerals on a strip 324 connected to the block and passing under a reading aperture 325, Fig. 2. If it is desired to give the voucher two impressions and the slip one, or vice versa, the hammeractuating cam 67 is provided with three lobes.

The vibratory device may be a sizing device of the type described in Specification 1275623 but in which the obstacle systems are in the form of five superimposed, vertically spaced decks (4), Fig. 1 (not shown) of sheet screening material, a tensioning means being provided for each deck. The frame portion 14 is provided with two rods, each slidably received in a stop member 22 which has a grooved abutment surface 24 and which is mounted upon a bar portion of a deflector plate 28 secured in the framework (2) and arranged to protect a vibrator motor (not shown) from damage by graded particles. The first resilient means 38 are in the form of Belleville washers which are enclosed within an annular chamber 32 in the sleeve 30 and which bear upon a face 35 of an annular member 34 secured to stop member 22 to force the sleeve 30 to the right so as to compress the second resilient means 46, i.e. a compression spring, against a washer 44 associated with a nut adjustably mounted on a threaded portion 42 of the rod 20, whereby the sheet screening material 8 is held under tension by the action of the washers. When the sheet screening material fails, as there is not sufficient spring reserve in the Belleville washers to fling the frame portion 14 via the rod 20 against the stop member 22, the compression spring 46 begins to lengthen thereby bringing the lip 18 of the portion 14 and the marginal portion of the sheet screening material into engagement with the groove 26 of the member 22.
