Title: Automatic devices for transmitting distress signals
IPC: H03B5/12
Filed: 1974-10-22
Abstract: 1477232 Radio signalling THOMSON-CSF 22 Oct 1974 [23 Oct 1973] 45714/74 Heading H4L An automatic radio transmitter arrangement, carried by an object such as a vehicle, includes a distress signal generator which operates in response to abnormal behaviour of the object. The generator includes a transistor 1 whose collector is connected to an LC oscillatory circuit 3, 4 and whose emitter is connected to a feedback inductor winding 5. The oscillatory circuit is coupled inductively to a transmitting antenna 10. The arrangement includes an incorporated supply source 2, a relay contact 11 for connecting the supply to the oscillatory circuit and an input circuit 20, 21, 16 connected to receive trigger signals from separate devices which generate the trigger signals in response to the abnormal behaviour, e.g. accelleration or deformation of the object. As shown in Fig. 1 the oscillator 1, 3, 5 is modulated by a multivibrator 6 co-operating with RC circuit 7, 8, so that bursts of R.F. varying in frequency are transmitted when the relay contact 11 is closed. This enables the distress signal to be picked up by both amplitude and frequency modulation receivers. When closed the contact 11 connects the transmitter circuit to both the battery 2 incorporated in the arrangement and to the vehicle battery via resistor 13 and protective diode 12. It is operated by a relay coil 18 in the event of a voltage appearing at an input 16 or on the lead 43 as a result of the operation of switching devices responding to abnormal acceleration or deceleration or to deformation of the vehicle body, for example. In one arrangement a conductive mass in the form of a grooved pulley is held by a pair of springs in an opening in a metal plate, attached to a vehicle, abnormal movement of the vehicle cuasing a contact to be made and a voltage applied to terminal 16. A deformation detector consisting of a fine wire in a breakable insulating sheath may be positioned along the coachwork and arranged to supply a voltage to input 21 of NAND gate 19 which receives the same voltage on input 20 via a sturdy protected cable so that if the input to 21 is interrupted the lead 43 is energized.

Abstract: 1537474 Electrical couplings SEALECTRO Ltd & D R EVANS 3 Nov 1976 [14 Nov 1975] 47070/75 Heading H2E In a method of making an electrical feedthrough, a tubular body 2 of dielectric material carrying a conductor 3 is disposed within a conductive sleeve 1, so that the conductor 3 extends longitudinally of the sleeve 1 and is physically spaced and electrically insulated by the body 2 from the sleeve, an end 11 of a radially outwardly extending flange 10 of the body being partially sheared against a surface of the sleeve 1 so as to effect an hermetic seal with the sleeve. As described in one embodiment (shown) the sleeve 1 comprises outer and inner cylindrical parts 4, 5 having a stepped portion 6 and a peripheral step 8 respectively between which is trapped the end 11 of the flange 10 to produce an annular shear seal (Fig. 3). The conductor 3 is provided with a reduced diameter portion, e.g. a groove defined between shoulders 16, 17 having a diameter larger than the inner diameter defined by an inner part 12 of flange 10. A body 15 dielectric material aids the deformation of part 12 after initial deformation has been effected by mounting the flange 10 over the reduced diameter portion of the conductor. The deformation may be arcuate as shown or, when the groove defined by shoulders 16, 17 is sufficiently narrow, radial (Fig. 5, not shown). The flange may comprise a separate ring element which encircles the sleeve. The feedthrough may be a coaxial feedthrough employed in a coaxial connector. The feedthrough may be adapted as a bulkhead connector for transmitting direct or alternating voltages and currents between two transmission devices separated by a bulkhead. Alternatively, the feedthrough may be adapted as a cable mounted connector for coupling one transmission cable to another or to electrical apparatus.

Title: Method and apparatus for use in an inductive sensor coin selector manufacture of carbon fibre
IPC: G07F7/02
Filed: 1972-10-12
Abstract: 1443934 Testing coins MARS Inc 8 Oct 1973 [12 Oct 1972] 47164/72 Heading G4V  A method of testing coins comprises subjecting a coin to an alternating magnetic field, producing a first signal indicative of the degree of interaction of the coin with the field, producing a second signal dependent on both the value of the first signal when a coin is in the field and its value when no coin is in the field, and comparing the value of the second signal with that expected for an acceptable coin. This arrangement corrects for changes in the operating parameters and in particular in the preferred structure (Figs. 1 and 2, not shown) where a coin passes between an inductor (20) and a conductive target (40) on opposed walls (32), (34) of a coin passageway and the walls are relatively movable to release jammed coins, for changes in the wall spacing. In the embodiment shown an oscillator 450 is connected to an inductor 420 adjacent the coin passageway and its output is also gated alternately to counters 470, 471 under the control of a flip-flop 461 and timing and reset pulse generator 460. One of the counters 470, 471 therefore stores the value of the oscillator frequency while the other is measuring it. When a coin arrival is detected by detector 455 the timing pulses from the generator 460 to the flip-flop 461 are blocked and one counter therefore stores the last frequency value while the other is connected to the oscillator for the duration of the testing period which comprises a plurality of timed intervals as determined by generator 460. A comparator 473 is connected between counters 470, 471 and controls a flipflop 485 so that when one count exceeds the other further pulses in each testing interval from the oscillator are counted into counter 490 via OR gate 487 and AND gate 489. The highest count received in counter 490 during the testing period is compared with values expected for a genuine coin. In a second embodiment (Fig. 3, not shown) a reference value of the frequency of oscillator (350) is stored in register (370) at predetermined intervals and after other events, e.g. switching on of the power to the circuit. A second register (371) is connected to the oscillator during the testing period and a unit (383) derives the arithmetic difference or another mathematical function of the values in registers (370), (371), the derived value being compared with predetermined limits by comparator 390. Alternatively the amplitude of the oscillator signal may be examined in which case registers (370), (371) may comprise capacitor circuits.

In preparing batches of articles for packaging, input conveyer means moves articles in succession in at least two side-by-side files and delivers the leading articles of the files to lifting members reciprocable in timed relation one with the other to elevate articles received thereon into the path of an output conveyer operable to deliver the articles to marshalling means arranged to urge the articles laterally of the direction of movement of the output conveyer into engagement one with another. In Figs. 2a, 2b, articles, e.g. fish fingers, are fed by an endless belt 11 in single file between guides 12 on to lifting members 14 which move the articles into the path of output conveyer pusher rods 18. The articles, as they travel along a plate 19, are urged laterally into engagement with one another by marshalling guides 16. Groups 1-3 and 4-6 of the lifting members are raised one after the other in timed relation with the rods 18, the arrangement being such that as one group is elevating a batch of articles for engagement by a rod 18 the other group is being lowered to receive a portion of a further row of articles. Leaf springs 25 extend from the ends of guides 16b, 16c, 16e and 16f and are pushed aside by the advancing articles. Should there be an incomplete batch of articles, detector means 26 for each row provides that the relevant lifting member 14 is not elevated. A carton supply conveyer 20 is operable in timed relation with the output conveyer to move opentopped cartons 24 to receive batches of articles. If no carton is present the lifting member 14 is not elevated, as before. The numbers of articles in a batch may be reduced by non-operation of the outermost files. In Fig. 4 (not shown) the batches are delivered to a take-off conveyer (32) which transfers the batches to packaging means. In a further construction Figs. 5A, 5B, 6A, 6B (not shown) articles such as cod steaks pass to marshalling means comprising stationary platforms (64, 65) disposed on opposite sides of a collating platform (66). Reciprocable pusher members (69, 70) alternately deliver rows of articles from a platform (64) or (65) to the platform 66. An endless acceleration conveyer (72) moves the articles to a batching unit whence the batches are advanced to packaging means (73). If the supply from one of machines (38= 41) should cease, the lifting member sequence is automatically changed to exclude the idle machine.

When the knob 2 is turned anti-clockwise the lever 15 is pivoted by the lug 9 so as to cock the hammer 17 and when a mark 7 on the knob is brought into alignment with a reference mark 5 pilot gas is allowed to flow and the hammer is released as parts 9 and 16 move out of engagement thereby producing a spark at a pilot burner of the heater. Further rotation of the knob brings marks 5 and 8 into alignment and a main gas flow is permitted. To turn off the heater the knob is turned clockwise and engagement of the lug 9 and arm 16 produces a pivoting motion about the striker pin 13 with which the hammer is in contact. The assembly may also be used with a burner safety device having a thermocouple for sensing a pilot flame.

Abstract: 1315766 R.M.S. voltage measurement ITT INDUSTRIES Inc 14 Oct 1971 [21 Oct 1970] 47838/71 Heading G1U A balanced bridge comprising resistors R1, R2, Fig.1, photo-resistors PR1, PR2 and associated equally energized lamps L1, L2 from a d.c. source B, is unbalanced by the application of a signal VE to be measured, which causes lamp L1 to shine more brightly and the impedance of the photo-resistors PR1 to decrease, resulting in an unbalance signal VD which is amplified A1 to apply an additional current to lamp L2 - this lamp being decoupled from lamp L1 by a capacitor CD - whose light output increases until it is just  below that of lamp L1 to restore the bridge almost to balance. The output signal from the amplifier, which will be a pure sinewave, will then be substantially proportioned to the r.m.s. valve of the signal VE and can be measured by a device ME. The circuit of Fig.1 is unstable since any unbalance signal from the bridge always increases the output from lamp L2 irrespective of whether the error signal is in phase (say) with the bridge supply G, indicating that the output from lamp L2 is too low, or whether it is out of phase, indicating that the output from lamp L2 is too high. This defect is overcome by the inclusion of a photoresistor PR3, Fig.2, in the feedback loop, this photoresistor being controlled by a phase detector DS, a threshold circuit CS and a lamp SC. When the out of balance signal VDfrom the bridge is in phase with the supply G, a signal SD from the phase detector actuates the threshold circuit CS, and the lamp L3, and the impedance of photo-resistor PR3 is low. However, if the out of balance signal is of the opposite phase, the lamp is not energized, the impedance of photo-resistor PR3 is high, and the feedback loop is effectively disabled, thus preventing a runaway condition developing. Inclusion of the threshold circuit CS ensures that the arrangement does not attempt to measure unknown signals VE of too low an r.m.s. value. A suitable phase discriminator and threshold circuit are described Fig.3, (not shown), and in a modification Fig.4, (not shown), for extending the low frequency response of the system, each photo-resistor PR1, PR2 and associated lamp are replaced by a parallel connected pair of photo-resistors and out of phase energized lamps.
