Preferably the successive testing of the appliances is controlled by computer. A circuit arrangement for monitoring the battery current comprises a plurality of resistive shunts R1-R6, any one of which may be selected by the computer, by actuating the appropriate relay Re1 24-29, for connection via a pair of terminals 1, 2 into one of the battery leads. The voltage across the selected shunt is smoothed (17A, B) and passed (16) via an A/D converter to the computer. Individual shunts may be protected by fuses 24-26, and overall protection is provided by a computer-controlled relay Rel 31 for shortcircuiting (28) the terminals 1, 2. Warning lights 18-23 indicate if any shunt fails. A first auxiliary relay Re1 30 enables the computer to short-circuit the ignition coil if this should be desirable for testing any particular appliance, and a second auxiliary relay 34 enables the computer to monitor the battery voltage.

Title: Improvements in or relating to radar systems
IPC: C11B1/02
Filed: 1959-03-02
Abstract: 905,975. Pulse radar. SOC. NOUVELLE ELECTRONIQUE. March 2, 1959 [March 4, 1958], No. 7174/59. Class 40 (7). Relates to a scanning pulse radar having a beam of finite width such that a single target will produce an echo pulse during each of a plurality n of successive pulse recurrence periods, the direction of the target being given by the direction of the beam axis when n/2 echoes have been received. According to the present invention N storage circuits are provided where N is the maximum possible value of n and these circuits are arranged in two equal groups I and II. When the leading edge of the beam encounters the target the echo I 1  received during the first pulse recurrence period T 1  is stored in the first storage circuit 14. If a corresponding echo I 2  is received in the next period T 2  the echo I 1  is transferred to the second storage circuit 15 and the echo I 2  is stored in the first storage circuit 14. This process is repeated so that each echo passes through all the storage circuits 14 ... 19 in turn and an output signal is produced by a comparator, Fig. 1 (not shown), coupled to the storage circuits when an equal number of echoes are stored in groups I and II of the storage circuits, the true bearing being given by # - N α/2, where # is the direction of the beam axis when the output signal is produced by the comparator and α is the angular movement of the beam axis during a pulse recurrence period. When four echoes I 1 -I 4  are produced by the target, the output signal is produced during the fifth recurrence period T 5 . The outputs from the storage circuits to the comparator may be weighted to give a required response characteristic. In order to deal with multiple targets of different range each storage circuit comprises a plurality of elements corresponding to different range intervals, the corresponding elements of the different storage circuits being interconnected and the echoes received during any one pulse recurrence period being applied to each element of the first storage circuit through a corresponding gate which is opened by a corresponding control pulse delayed with respect to the transmitted pulse by an amount corresponding to the range value of the element. In order to discriminate against interfering signals the system may produce an output only in response to signals of equal range received during a predetermined number of pulse recurrence periods. The storage elements may comprise bi-stable trigger circuits or magnetic cores.

March 10, 1931, No. 7436. [Class 135.] An electric-motor operated three-way valve 25 forms part. of a plant wherein a steam generator 10 is connected. to a turbine 24 or other prime mover by a pipe 23 so that the flow of steam is directed either to the turbine or to a condenser 21 or elsewhere in accordance with the temperature of the steam. A thermostat 30 controls the operation of the stop valve 25 so that only steam within a certain temperature range is admitted to the turbine, steam of other temperatures being byepassed. The thermostat is linked to a bell crank with an arm 32, which acts as a switch, and when moved to either right or left on a rise or fall in temperature of the steam outside the prescribed range, the arm closes a circuit to start up the motor 35. The motor, through gearing, moves the spindle of the valve 25 so that steam is byepassed from the turbine. An electric relay 39 stops the motor when the valve is seated. The valve is returned to normal position by hand.
