Title: Improvements in and relating to electric remote metering systems
IPC: G08C19/26
Filed: 1930-12-09
Abstract: 369,247. Electric signalling systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Price, D. R. ; 34, Orient Court, Swampscott, Massachusetts, U.S.A.) Dec. 9, 1930, No. 37175. Convention date, Dec. 13, 1929. [Class 40 (i).] Means for indicating at a remote point the readings of a meter comprise a transformer having a primary winding connected to a source of direct current and adapted to receive current impulses caused by the interruption of a circuit through a resistance in parallel with the winding, the transformer and resistance being such that substantially equal current impulses are induced in the secondary winding of the transformer regardless of considerable variation in the voltage of the source of direct current. As shown, a wattmeter 10 connected to integrate the power in a circuit 11 is adapted to transmit electrical impulses by means of a contact arm 12. This arm engages contacts 23, 24 connected as shown, to the coil of a polarized relay 15 which operates a switch 16 to short-circuit transformer winding 25 through a resistance 28. The secondary winding 26 is connected to a rectifier 20 and a condenser 19, and may be connected by switches 33, 34 to an instrument 13 for giving continuous readings or to a recording demand meter 14. The action of switch 16 causes high voltage impulses to be induced in the secondary winding 26, these impulses being rectified at 20 and serving to charge the condenser 19. When the instrument 13 is operatively connected a steady indication is given thereon proportional to the speed of the meter 10. With the demand meter in use, the impulses through the winding 26 are stored in the condenser until the engagement of contacts 36, 37 which are closed at predetermined intervals by a clock 35. By connecting additional impulse systems to the condenser 19 as indicated at 17<1>, 20<1> summation indications may be obtained. In order that the impulses induced in winding 26 may be substantially constant during considerable variation in the voltage of the supply at 18, adjustment of the system is necessary, as explained by reference to the saturation curve of the transformer, Fig. 2. Assuming for example that the voltage at 18 may vary between 110 and 150 volts, the curve between points 29 and 30 represents the magnetism of the transformer during an impulse when the switch 16 is open, the voltage being 110 volts. The curve from 31 to 32 corresponds to a voltage of 150 volts. The resistance 28 is adjusted so that the difference between the ordinates of points 29 and 30 equals the difference between the ordinates of points 31 and 32, the effect being to produce substantially constant impulses charging the condenser. The transformer has preferably a laminated iron core containing a reduced portion at the centre. The Specification as open to inspection under Sect. 91 (3) (a) indicates the use of a time delay relay instead of the rectifier 20. This subjectmatter does not appear in the Specification as accepted.

Abstract: 380,134. Time-recorders for workmen &c. ; electrical step-by-step mechanism. GLEDHILL, A. H., Trinity Works, Halifax, Yorkshire. June 12, 1931, No. 17079. [Class 106 (iv).] A driving mechanism for a time-recorder comprises an electromagnetically operated ratchet device controlled by impulses from a master clock and a particular form of mechanism whereby parts of the time-recording means are actuated only bv alternate or other selected impulses from the clock. As shown in Figs. 1 and 2, an electromagnet A energized every half-minute rocks an armature lever B<1> carrying a set of spring-controlled pawls b<2>, b<3>, b<4>. The pawls b<2>, b<3> engage the teeth of wheels C, C<1>, of equal diameter rotatably mounted on a spindle D. The wheel C is an ordinary ratchet wheel and the other wheel C<1> has ratchet teeth C<1> which alternate with uncut portions C<2>. The pawl b<3> is connected by a link b<5> with the pawl b<4>, which pawl co-operates with a ratchet wheel E of half the diameter and half the number of teeth of the wheel C and is also rotatably mounted on the spindle D. By means of this arrangement the ratchet wheel C is advanced a tooth every half-minute while the wheel E is advanced one tooth every minute by reason of the pawl b<4> being held out by the uncut portions of the wheel C<1>. The wheel E is formed with a slot e<1> with which engages a pin e<2> projecting from the half-minute driving wheels to permit of the relative movement of one tooth space. The pin-and-slot arrangement enables the hands of the time-recording mechanism to be set without upsetting the synchronization between the various wheels.

Abstract: 1277975 Transistor bi-stables SIEMENS AG 12 Aug 1970 [13 Aug 1969] 38748/70 Heading H3T  Two emitter-coupled current switches T1, T2 and T5, T6, T7 are connected as shown to one another and to emitter followers T3, T4 and T8 to provide a R-5 flip-flop in which R over-rides S if both are 1 at the same time, to ensure that Q and Q are always different and not indeterminate. This is achieved by the so-called "wired-or" connection of T3, T4 outputs and the "wired- and" connection of T1, T5 collectors. Thus if R is high so that Q is low and Q high; then if S should also go high so that T4 base goes low, T3 still holds Q high. In an improved embodiment (Fig. 4, not shown) a further transistor T9 is connected across T6 and T7 and is controlled by R to ensure that if T1 is on and drawing collector current through W2, then T5 cannot simultaneously be on to double the current in W2. Such current doubling produces undesirable variations in T8 base potential which are not wholly avoided even with the diode D of Fig. 1. A double emitter transistor is used for T8, one emitter providing the feedback and one the output Q.
