Title: Improvements in or relating to indicating or recording apparatus
IPC: G01R13/04
Filed: 1929-05-29
Abstract: 329,852. Electrical Improvements, Ltd., Beard, J. R., and Porter, G. L. May 29, 1929. Indicating maximum movements; particular readings.-In an apparatus adapted to indicate or record two quantities means are provided whereby an indication of one quantity is obtained that corresponds to a predetermined, value of the other quantity. The apparatus may comprise two instruments or two parts of one instrument one of which has a pointer provided with braking means and the other has means for controlling the brake to release the pointer. The invention is shown applied to electric metering systems. In one form, as shown in Fig. 1, an ammeter A and voltmeter B connected in a circuit E are so arranged that the pointer A<2> of the ammeter controls an electromagnetic brake C, D on the pointer B<1> of the voltmeter. The pointer A<2> cooperates with a maximum indicator A<3> through contacts A<4>, A<5>, adapted to complete the circuit of the electromagnet D to release the brake block C from a disc on the pointer B<1> to permit the pointer B<1> to move to a position to indicate the voltage when the load on the system is a maximum. A minimum pointer may be substituted for the maximum. In an electric power system where it is desirable to know the power factor when the kilowatt demand is a maximum a watthour meter F and reactive watt-hour meter G are combined as. shown in Fig. 2. The shaft F<2> of the metering mechanism F<1> drives a shaft F<3> through a clutch J, J<1> to actuate an arm F<4> and maximum pointer F<5>. The disc J is slidable axially under the control of the armature K of an electromagnet L to free the arm F<4> to permit the spring N to return it to zero position. The electromagnet L is energized through the contacts M<1> of a time switch M. The switch G<2> of the metering mechanism G<1> drives in a similar manner the shaft G<3> flexibly connected through a spring S to a disc G<5> on a pointer G<4> which is retained in set position by a brake block P controlled by a release electromagnet R. The arm F<4> carries a contact 0' adapted to co-operate with one or other of the contacts O, O<2> which latter contacts are arranged in the circuits of the electromagnets Rand L<1> respectively. When the arm F<4> is reset the shaft G<3> is reset and the spring S is unwound and when the arm F<4> is at its maximum the electromagnet R is energized and the brake is freed to permit the spring S to move the arm G<4>. Undue oscillation of the arm G<4> is prevented by means of a damping device such as a gear wheel (not shown) on the disc G<5> driving a wind vane. In a modification shown in Fig. 5, the brake blocks W<2> of a plurality of meters U, U<1>, U<2> are released periodically by a clock-driven cam X<2> co-operating with contact arms Y, Y<1>, the arm Y<1> being slightly shorter than the arm Y to give a short time " make and break," the time being the minimum amount required for the pointers W to move to their new positions.

Filed: 1970-04-10
Abstract: 1276948 Track circuit signalling system COMPAGNIE DE SIGNAUX ET D'ENTREPRISES ELECTRIQUES 10 April 1970 [7 Jan 1970] 17264/70 Heading B7N In a track circuit signalling system for detecting track occupation and for conveying information to a train in which the track circuit signal is a carrier frequency modulated by a number of different frequency information tones, the carrier is modulated at low frequencies and the modulation signals after demodulation on the train or at the track circuit end are multiplied to facilitate separation by band pass filters. Alternate circuits operate with different carrier frequencies so that a signal is picked up on the train by either pick-up coil 2 or 3, each tuned to one of the frequencies. Assume a signal is picked up by coil 2 this is amplified at 4 and passed via band pass filter 8 to a second amplifier 10. This supplies a first output which picks up relay 12 so that the power supply V 0  to the second channel is cut off by contact 22, slow to operate relay 23 is energized via contact 20 and the amplifier output is applied via contact 21 and contact 24 of relay 23 when this picks up, to a demodulator 29. The demodulated signals are first multiplied by 2 in unit 30 and then applied to the common input of a series of multiply by 8 circuits M1-M7 which have tuned inputs. The multipliers feed band pass filters F1-F7 each of which supplies an output, when its associated tone is present to operate a signalling relay R1- R7 controlling lamps V1-V7.

Abstract: 1463536 Tape feed means; labelling DYMO INDUSTRIES Inc 19 April 1974 [21 April 1973] 17316/74 Headings B8M and B8F A printing and dispensing tool comprises a reel 44 of tape 1 carrying labels 43, a printing table 39, a printing head 40 and a forked rocking arm 3 pivoted about spindle 4 and carrying between the ends of forks 3a, 3b a gripping latch 6 and a guide surface 9 which coact to step the tape forwards. The tape is fed from roll 44, over table 39, around edge 42, under guide tongue 29 and between latch 6 and surface 9 and between stop pawl 15 and fixed guide web 27. On squeezing handle 31 (which terminates in forks 32a, 32b) it pivots about 37. A pin 33 on each fork causes arm 3 to rotate counterclockwise as seen in Fig. 1 until latch 6 moves up the tape a distance of one label. At this point feelers 11 come to a recess on each edge of the tape and drop into grooves 13 in guide 9 thereby bringing latch 6 closer to guide 9 so that teeth 6 pass through the tape into grooves 12 and edges 14 clamp the tape against guide 9. Simultaneously head 40 prints a label. On release of handle 31 forked arm 3 rotates clockwise to return latch 6 to the position of Fig. 1 thereby stepping the tape forwards. The printed label curls around roller 41 for removal. In the rest position shown spring 22 causes pivoted link 20 to urge teeth 16 of locking pawl 15 into holes 28 of fixed guide web 27, thereby preventing forwards movement of tape 1. During the rocking of arm 3 surface 25 contacts pawl 24 causing link 20 to lift and release locking pawl 15. Likewise surface 45 of clamp arm 38 which normally presses tape 1 against surface 46 is lifted during the rocking of arm 3. In a second embodiment, Fig. 6, the clamp arm is omitted.
