Title: Improvements in or relating to alarm annunciators
IPC: G08B26/00
Filed: 1963-11-12
Abstract: 1,070,468. Alarm systems. E. I. DU PONT DE NEMOURS & CO. Nov. 12, 1963 [Nov. 20, 1962], No. 44598/63. Heading G4N. [Also in Division H3] An electrical annunciator comprises two parallel branches across a supply, each having an indicator lamp; means responsive to an abnormal condition at a monitoring point for establishing a predetermined state of illumination of the lamps; and manual means for changing the state of illumination of the second lamp. In one arrangement, Fig. 4, an abnormal condition applies a negative potential on line 50 to cause negative resistance diode 1411 to switch to its conducting state and illuminate lamp 16<SP>11</SP>. At the same time the change in charge on capacitor 55 Switches diode 19<SP>11</SP> to provide a circuit to lamps 20<SP>11</SP>, 20<SP>11</SP>a. The negative circuit 64 to these lamps is completed via a flasher 73, Fig. 5, which also supplies an audible alarm 70. Receipt of an alarm is acknowledged by operating ganged buttons 65, 66 which extinguish lamps 20<SP>11</SP>, 20<SP>11</SP>a and silence the audible alarm. Upon cessation of an abnormal condition the red lamp 16<SP>11</SP> is extinguished and a ringback lamp (78), Fig. 6 (not shown), is lit and the ringback alarm (84), Fig. 5 (not shown), is sounded. These are cancelled by ganged push buttons (87, 89). Further branch circuits comprising a lamp and a negative resistance diode may also be provided to indicate which alarm is " first on," Fig. 7 (not shown). If the abnormal condition ceases before it is acknowledged the lamps 20<SP>11</SP> and 20<SP>11</SP>a remain lit. In a modification, the acknowledge lamps 20111, 20<SP>111</SP>a, Fig. 4, are also extinguished by the OFF signal on line 52. A transistor may be used in place of the diode 49 with the ON and OFF signals applied to its base, Figs. 1-3 (not shown). The negative resistance diodes and lamps may be replaced by neons which serve both purposes, Figs. 8-10 (not shown).

Title: Typographical composing computer and indicator
IPC: B41B7/04
Filed: 1960-12-29
Abstract: 944,041. Strip-perforating machines; justifying type. P. J. B. ASTIER. Dec. 29, 1960 [Dec. 29, 1959], No. 44631/60. Drawings to Specification. Heading B6W. Each key of a keyboard, of the kind used in a typographical composing machine, for punching code holes in a tape for controlling a composing machine, actuates, through a modified cam as described in Specification 938,294 having an actuation time of 3/ 1000 -1/ 30  seconds, two pairs of electrical contacts, which are in the place of the matrix escapement device of a composing machine, one pair of contacts actuating the punch mechanism and the other pair actuating a device for indicating when the composed line is in the justification range. Signals from the latter pair of contacts pass to the decimal input leads of a programmer, and thence to binary output leads representing character width. The output signals are fed into a computer comprising a plurality of relays, acting as a binary counter and memory device, each 32 counting units consisting of three typographical units. Output signals from the counter stages from 25 upwards energize selectively a series of relays controlling a " tree " circuit, whereby current from another source is passed to a selected one of 120 lamps positioned behind a translucent character width scale at intervals of three typographical units, thereby indicating at any moment the length of the composed line. A space indicator scale is positioned above the zero end of the character width scale. Signals from the space key pass directly to relays controlling a further " tree " circuit for lamps behind the space scale. If the minimum space is 3 units and the maximum 6 units, the scale is graduated according to the difference of 3 units (i.e. possible expansion for justification), there being 16 lamps spaced 3 units apart. If the maximum is 9 units, only the even numbered lamps are used, a manually operated switch transferring the signals a stage up the binary scale, there being seven further lamps, numbered 18-30, even numbers only, spaced units apart beyond lamp number 16. When lamps in the two scales aligned with each other are lit, the line being ready for justifying, pairs of relays each in parallel with its corresponding lamp are energized, and the contacts thereof, being in series with each other, close a circuit to an alarm bell or lamp. Actuation of an " end-of-line " key returns all relays to their original states.

Title: Detection of distributed defects in gear assemblies

Filed: 1971-10-04
Abstract: 1369050 Vibration measurement GENERAL ELECTRIC CO 4 Oct 1971 [30 Oct 1970] 46021/71 Heading H4D  A distributed defect (e.g. misalignment, eccentricity, uneven wear or excessive bearing wear) in a pair of meshing gears is detected by analysing a signal derived from a vibration sensor acoustically coupled to the gears, the signal having a periodicity equal to the tooth meshing periodicity and having an amplitude modulation (caused by the defect) with a periodicity equal to or a submultiple of the period of rotation of one of the gears. In the Fig. 6 embodiment the amplified and filtered output of vibration sensor 14, having a periodicity equal to the tooth meshing period of a driven gear, is rectified at 33 then sampled in analyser 34. A tachometer 15 coupled to a driving gear provides a signal which is frequencyconverted at 35 (to allow for the gear ratio) then used to synchronize the sampling in analyser 34. The analyser stores the sample amplitudes in successive sequences each comprising several meshing periods, and sums respective samples from one sequence with corresponding samples from other sequences to average the rectified signal over several sequences. The depth of modulation of the resulting averaged signal is computed (after amplification at 40) by detecting the signal modulation peak amplitude at 41, detecting the instantaneous modulation amplitude (i.e. the modulation envelope) at 43, subtracting the latter from the modulation peak amplitude in difference amplifier 45, and dividing the difference by the modulation peak amplitude at 46. The resulting modulation depth signal is smoothed in a long time-constant network 47 (to prevent spurious perturbations) and then applied to a meter relay 48 which, at a predetermined modulation depth, actuates an alarm 49.

Abstract: 1410234 Cathode-ray tube circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 6 Oct 1972 [9 Oct 1971] 46206/72 Heading H4T In an arrangement for correcting deflection errors in a colour television display tube the horizontal and vertical deflection coils are each formed as two symmetrical coil halves 17, 18 and 19, 20 respectively (Fig. 2) wound on a toroidal core 16 and connected to respective scanning generators 8 and 9, a correction waveform generator 23 producing a correction current 1K in the coils 19, 20 which, in known manner results in the production of a first correction quadripole field on the diagonals U, V and the current i<1>K induced in the coils 17, 18 resulting in the production of a second correction quadripole field coinciding with the first quadripole field. Since, as shown, the magnetic fluxes #K and #<1>K generated, respectively by the currents iK and i<1>K, oppose each other in the core, there is only a small flux circulating in the core and therefore the losses are low so that generator 23 is not required to supply a large (loss) power and additionally by arranging the winding directions of coils 17 and 18 such that the voltage between points A and B is zero, the fluxes #K and #<1>K have the same direction in the space within the core and reinforce each other in the production of the quadripoles. The impedances 21 and 22 prevent interaction between generator 23 and generator 9. With this arrangement isotropic astigmatic errors can be corrected without the requirement for a correction current generator of high power capability the correction current being made proportional to the instantaneous magnitude of the horizontal deflection current 1#H when correction is required in the X-direction and proportional to the instantaneous magnitude of the vertical deflection iV when correction is required in the Y-direction the connections 26 or 27 supplying the required information to generator 23. The arrangement may be varied as shown in Fig. 3 in which the generators 9 and 23 are interchanged so that coils 19 and 20 are in parallel for the current iV (instead of in series) and in series (instead of in parallel) for the current 1K, or as shown in Fig. 6 where separate correction current generator 23, 23<1> for the Y and X directions are employed. When correction for anisotropic astigmatism is required the axes of the quadripole field must coincide with the X and Y axes and this is achieved by the arrangement shown in Fig. 7 in which, e.g. the vertical deflection coils are each formed as two equal parts 19<1>, 19<11> and 20<1>, 22<11>.
