In an A.T.C. system in which a tuned circuit L.C. positioned adjacent a railway track establishes a positive feedback path between the input and output circuits of an aperiodic oscillator on a passing train which thereby oscillates at the frequency of the tuned circuit and initiates an action on the train characteristic of that frequency, the frequency to which the circuit is tuned can be altered by one or more of a number of parallel connected circuits, each comprising a capacitor C 1 , C 2.  or C 3  connected in series with a saturable choke L 1 , L 2  or L 3 . When e.g., choke L 1  is not saturated its impedance is sufficiently high to prevent capacitor C 1  effecting the frequency to which the circuit is tuned, when however the choke is saturated by direct current applied to the saturating winding via terminals b<SP>1</SP> its impedance drops and capacitor C 1  is effectively connected in shunt with capacitor C and lowers the frequency to which the circuit is tuned.

Title: Card reader
IPC: G06K13/06
Filed: 1975-03-26
Abstract: Each information position of the data matrix of M rows and N columns corresponds to a binary zero or a binary one. The device contains means (28, 29) for receiving and guiding the card along a control area, in each case a number of row data and column data detection elements (34, 32) which are at right angles to one another, and circuit means connected to the latter. When the leading edge of the card passes the row data detection elements (34), these circuit means activate the associated column data detection elements (32) in order to receive from the latter output signals corresponding to the binary value of the information position read. These output signals are successively supplied to a memory which stores them at particular address locations in accordance with their correlation with the data matrix so that, after the card has passed through the control area, a complete arrangement of the information recorded thereon is available. <IMAGE>

Abstract: 1442778 Gear-pumps and motors ZAHNRADFABRIK FRIEDRICHSHAFEN AG 12 Oct 1973 [12 Oct 1972] 47750/73 Heading F1F In an hydraulic gear-pump or motor having meshing gears 1, 2 with involute teeth, the highpressure and low-pressure zones 4, 3 encroach upon the intermesh zone DE to the extent that the length of the intermeshing zone which is out of communication with both high-pressure and low-pressure zones, i.e. EG, is equal to the base circle pitch of the gear teeth. This avoids compression of the fluid trapped in the space 6 between the meshing teeth whilst maintaining a seal between high and low-pressure zones, and reduces noise. To form accurately defined high and low-pressure zones, a blind bore 5 may be drilled in one or both side plates of the housing in one or both zones. The bore(s) are located to touch the root circle of one or both gears. The gears may be externally meshing or internally meshing, Fig. 5 (not shown).

Abstract: 1,200,773. Analogue/digital converters. SOLARTRON ELECTRIC GROUP Ltd. 11 Oct., 1968 [25 Oct., 1967], No. 48587/67. Heading G4H. An analogue/digital converter includes an integrator integrating the unknown signal and a reference signal -V R , two comparators 12, 13 (Fig. 1), comparing the output V 0  of the integrator with signals V 1 , V 2  at least one of which V 2  is variable with time, and a bi-stable device 17 controlled by the comparators and switched to its first state when V 0  = V 1  and to its second state when V 0  = V 2  to apply the reference signal -V R  to the integrator and to enable a gate 18 to pass clock pulses to a counter. The unknown signal V u  is continuously applied to the integrator. The count may be displayed. In one embodiment (Fig. 2) the signal V 1  = 0 and the signal V 2  is a linearly increasing sawtooth signal of period T, the output V 0  of the integrator decreasing until V 0  = V 2  when the bi-stable is switched to enable the gate 18 and to apply the signal -V R  to the integrator to cause the signal V 0  to increase until V 1  = 0 when the bi-stable is switched again. This process is repeated for one period T. In another embodiment V 1  is also a linearly increasing sawtooth signal of period T (Fig. 3, not shown), V 1  being of smaller amplitude then V 2 . In a third embodiment V 1  is fixed and V 2  is a linearly decreasing signal, the time interval when -V R  is connected being then counted. The sawtooth waveforms could be replaced by staircase signals and the reference signal by a pulse train. To measure bi-polar inputs two sets of comparators 12, 13 are used each associated with a bi-stable, the bi-stables controlling a single counter and the polarity being indicated by that bi-stable which switches to its second state.
