Patent GB-868781-A (GB)
Title: Magneto-absorption flux meter and gradiometer
IPC: G01R33/022
Filed: 1957-06-26
Abstract: 868,781. Magnetic tests. VARIAN ASSOCIATES. June 26, 1957 [July 5, 1956], No. 20215/57. Class 37. The strength of the magnetic field is measured by causing it to magnetize an object of high magnetic permeability, applying a cyclically varying field to the specimen and. determining the absorption of energy from a radio-frequency source applying a third field to the object. As shown (Fig. 1) a bar of iron is positioned in a coil 12 supplied with radio-frequency current from the output of an oscillating detector 13. A further pair of coils 14, 15 aligned with the specimen is fed from the output of an audio-frequency sweep generator 16 also feeding a phase detector 19. The specimen is aligned with the field H<SP>1</SP> to be measured. In the absence of field H<SP>1</SP>, the detector produces an output at the second and higher harmonics of the sweep frequency (Fig. 3a). When field H<SP>1</SP> is applied the envelope of the waveform is at the fundamental frequency shown dotted in Fig. 4a and this envelope has an amplitude dependent on the strength and a phase sense depending on the direction of field H<SP>1</SP>. The output of the oscillating detector is indicated on an oscilloscope 18 and the strength of the field may be measured by neutralizing it by means of a calibrated current source 26 feeding a coil 25. The output of the detector may be fed through a filter 21 which removes the second harmonic to a phase detector 19 receiving a reference signal from the sweep generator and indicated on recorder 22. In a further arrangement (Fig. 2, not shown) the output of the phase detector is used to feed a coil to neutralize the field to be measured, the current to this coil being measured. To measure field gradient this last arrangement is duplicated using a pair of axially aligned specimens with fixed spacing the outputs of the two phase detectors being compared in a different amplifier and indicated on a meter which gives an indication of field gradient. Fig. 8 shows the specimens which consist of a pair of high-permeability iron needles 51, 52 embedded in quartz rods 54, 56. The rods are attached at one end to housing 56 and are joined together at the other end by a spring 58. The housing is filled with a fluid 59 to damp out vibration. Each needle is surrounded by three coils 31, 35, 43 to produce the R.F., sweep and neutralizing fields. Specification 834,010 is referred to.

Title: A ribbon guide for typewriting machines
Inventor: GROPE WILLY
IPC: B41J33/48
Filed: 1958-06-26
Abstract: 873,142. Ink ribbon mechanisms. OLYMPIA WERKE A. G. June 26, 1958, No. 20528/58. Class 100(4) An ink ribbon guide, vibrator, feeding and reversing device has the ink ribbon running parallel to the platen for a considerable distance over which it is moved close to the platen on each impression without stretching the ribbon. A cross member 2 mounts ribbon spools 30, 31, a control lever 8, and a drive lever 12. The ribbon runs from the spool 30 over guide rollers 27, 28 of carrier rods 21, 22 to the spool 31. The guide rods are articulated to intermediate levers 16, 17 pivotally mounted on pins 18, 19 and connected by pins 14, 15 to the control lever 8. On each impression a rod 20 pivots the control lever 8 clockwise and thus while the intermediate levers 16, 17 move the carrier rods and ribbon to the dot dash position shown, pins 24, 25 on the cross-bar 2 engaging slots 21a, 22a of the rods 21, 22 move them inwards as well as forwards to prevent tensioning of the ink ribbon. Ink ribbon feed and reversal is effected by a drive lever 12 having a pin and a slot connection 34, 12a with the control lever 8 which as it pivots on impression causes an extension of the arm to engage a ratchet wheel 33 to rotate the spool 31 until the reduction of the diameter of the ribbon on the spool 30 forces a three armed lever 43 to pivot until its projection 43c engages the lever 12 to cause the pin 34 to ride to the other end of the slot 12a. On further actuation of the lever 12 it will engage a ratchet wheel 32 of the spool 30 to feed the ribbon in the reverse direction. In modifications described the intermediate levers 16, 17 coact by a pin and slot connection while only one lever is connected to the control lever 8 and the sliding carrier rods 21, 22 are replaced by pivotal two arm levers which engage the levers 16, 17 with a pin and slot connection.

Title: Improvements in bridge construction
IPC: E01D6/00
Filed: 1930-07-08
Abstract: 357,305. Bridges .BLAKESLEY, J. H., 3, Central Buildings, Westminster. July 8, 1930, No. 20650. [Class 20 (i).] A bridge deck or roadway is carried by spaced supports dividing i t into bays, the construction being such that the natural period of vibration of each section of roadway is different from and has no harmonic common to the natural period of vibration of contiguous sections, so that accumulated or reinforced vibrations are avoided. This result is secured by varying the dimensions of the bays, the weight of the road section being constant, or alternatively by keeping the dimensions of the bays constant and varying the weight of road section, or further, by a combination of these methods. As shown in an elliptic arched bridge the transverse supports B are disposed at converging and diverging angles to the transverse direction, Fig. 2, or in a zig-zag fashion, Fig. 3, to vary the dimensions of contiguous bays ; or in a built-up bridge the transverse supports E, E<1>, E<2> are placed in pairs at varying distances. In the longitudinal direction the longitudinal supports may be arranged to converge and the depths of the roadway may be varied abruptly to secure the necessary variation in vibration period.

After a dielectric strip 16 adhesive on both faces has been made to adhere to the bus-bar and to the lead 13, a further strip 17 adhesive on one side is placed over the lead 13 and strip 16 to hold and maintain a portion of the lead in contact with the strip 16 along the bar 12. The strip 17 may extend to the inner edge of the bus-bar and to the side edge of the glass sheet, or may be continued around to the face of the uncoated side of the sheet. The strip 16 need not carry any adhesive or need carry adhesive on one side only. An additional adhesive coating may be employed between each bus-bar and strip 16. If the insulation 14 on the lead extends up to the soldered joint the strip 16 may be dispensed with.

Abstract: 1498127 Television NISSAN MOTOR CO Ltd 16 May 1975 [25 May 1974] 20914/75 Heading H4F Bandwidth reduction in a video telephone system is achieved by dividing the 4 MHz bandwidth signal from camera 11, Fig. 1, into high and low frequency components. The signal is applied to a low pass filter 12 of pass band 0-1 MHz and to a band pass filter 13 of 2-3 MHz pass band. The components are modulated on to carriers by respective modulators 14, 16 supplied with 900 MHz and 898 MHz so that signals in the band 900 to 901 MHz are provided. A switch 18, driven at the line rate by sync. generator 19, selects alternately, a line of low frequency components and a line of high frequency components for transmission over a 1 MHz band pass channel 10. At the receiver sync. is extracted which drives a switch 22 to pass alternate lines to respective demodulators. Each demodulated high or low frequency component is stored in a respective one line delay and added to the subsequent low or high frequency component of the adjacent line in a mixer stage prior to display. This eliminates a striped effect produced by displaying adjacent lines of differing frequency range signal. A system for normally selecting a high pass band of either 2-3 MHz or 3-4 MHz, for the high frequency component, is described with reference to Figs. 2 and 3 (not shown).
