Title: Electric measuring device
IPC: G01L1/08
Filed: 1964-07-02
Abstract: 1,072,367. Measuring fluid flow electrically. CONTINENTAL ELEKTROINDUSTRIE A. G. [trading as CONTINENTAL ELEKTROINDUSTRIE ASKANIA-WERKE A.G.]. July 2, 1964 [July 2, 1963], No. 27409/64. Heading G1N. A force F derived from some variable to be measured, for example fluid flow, unbalances a pivoted beam arrangement against the action of a spring; this unbalance is detected by a transducer which produces an A. C. proportional to the degree of unbalance and the A. C. is converted to a corresponding D. C. current in an amplifier 5 and fed to an electromagnetic arrangement to rebalance the beam. In addition, a high impedance source 9 produces a constant current and both the amplifier and source are shunted by diodes 19, 15. The arrangement is that, if the output from amplifier 5 exceeds that from source 9, the latter is short circuited and the entire control is exercised by the transducer whereas, if the current from 5 falls below that from 9 the former is short-circuited and the device is rebalanced by the fixed current. The double coil arrangement in 6 gives a square law relation so that the current in 16 is directly proportional to fluid flow. In a modification, Fig. 3 (not shown) the loop AB also contains a further rebalancing electromagnet acting on the beam.

Title: Improvements in or connected with shooting cinema targets
IPC: F41J9/14
Filed: 1926-11-08
Abstract: 278,198. Brewer, G., (Zeiss-Ikon Akt. Ges.). Nov. 8, 1926. Kinematograph apparatus.-In target apparatus a brake on the projector is caused by the impact of the bullet to stop the projector with a complete image in the gate; a flexible wall behind the screen may control the circuit of an electromagnet by which the operation of the brake mechanism is started, impact of the bullet with the wall causing the distance between its ends to be shortened and a switch to be closed. Fig. 3 shows brake mechanism in which braking-jaws 23, 24 are carried by slides 20, 21 connected by a spring 26 and pivoted arms 18, 19. When the projector is in use, a slot 35 in the arm 18 is engaged by a nose 31 on a bar 32 carried by a spindle 30 in a sleeve 29 turning on an axis 28, the jaws 23, 24 being thereby held away from a braking-drum 25<1>. The arms 18, 19 are pivoted to the moving core 14 of an electromagnet 13; the impact of the bullet causes the magnet 13 to be energized, and the core 14, arms 18, 19, sleeve 29, &c. to be moved, the brake-jaws 23, 24 being thereby brought nearer to the drum 25<1>, and an arm 33 on the spindle 30 being moved into position to be engaged by a pin 37 on a flywheel 25. Further rotation of the flywheel causes the pin 37 to engage and turn the arm 33, thereby releasing the bar 32 from the arm 18, and enabling the spring 26 to pull the jaws 23, 24 on to the drum 25'; the pin 37 is so positioned that the projector stops with a complete picture in the gate. Switches 41, 42 are opened, when braking is effected, to break the circuits of the projector motor and the magnet 13. The target may comprise a projection screen 1, Fig. 1, a thin wooden partition 2, and a number of parallel flexible steel strips 3 forming a wall behind the partition 2. Each strip is pivoted at its upper end 4, and is connected to an angle lever 6 pivoted at 5 and carrying a set-screw 9. All the set-screws engage one strip 11, rocking on an axis 10, and carrying a nose 12 normally holding a bar 43 in position against the longitudinal pull of a spring. Impact of a bullet on one of the strips 3 causes it to bend, and the bar 43 to be released. The bar 43 carries a switch arm in the circuit of the electromagnet 13, and a switch arm in the circuit of the hall lights, both circuits being completed when the bar is moved by the spring.
