Title: Improvements in cinematograph apparatus especially applicable for giving instructionin anti-aircraft gunnery
IPC: G03B29/00
Filed: 1926-03-29
Abstract: 273,385. Krohn, V. R., and Haszard, G. F. March 29, 1926. Optical-projection apparatus; applied kinematography.-Kinematographic apparatus especially applicable for giving instruction in anti-aircraft gunnery and course-plotting against moving targets comprises means for projecting the picture of a moving target on a screen combined with means for simultaneously projecting, on to the same screen, a second image or images, such as shell bursts, produced on a base independent of the kinematograph film. The invention comprises also the combination with kinematographic apparatus for projecting a picture of a moving target of which the actual gunnery data has been determined of means for enabling a corresponding relative angular movement to be effected between the image and the observer. The apparatus shown diagrammatically comprises a kinematographic projector a, e focussed on to a glass screen b, apparatus f for marking shell bursts on the screen b and a projecting lens c and prism g for projecting the image from the glass screen b on to a receiving screen (not shown) which is preferably a concave cylindrical screen having its axis on the axis of the horizontal prism g. The moving picture is produced from a film representing the flight of an aeroplane on a known course at a known height and speed, angles of sight and bearing being noted against time when taking the film. The image is moved up or down on the screen to correspond to the previously recorded angle of sight by rotating the prism g by a handle i<2>, which is moved to keep a pointer i on a curve on a chart i<1>. Change of bearing is simulated by rotating the platform of the observer. The bursts are marked on the screen b by apparatus f having a device like a typewriter key adapted to be operated by an electromagnetic device so that when the circuit is completed the key is operated and an ink mark is made on the screen. The apparatus f is moved laterally and vertically by mechanism driven by two differential gears o, r. One side of the gear o is moved in accordance with the true lateral deflection as indicated by a chart n' and the other side is moved in accordance with the ordered deflection indicated on a scale p' so that the movement of the burst apparatus f is the difference between the true and ordered deflections. The differential gear r is similarly operated by reference to a chart q<1> for true vertical deflection and a scale s<1> for ordered deflection. The time of flight is indicated by the movement of pointers t' t<2> with reference to a drum t bearing curves of fuze times and rotated according to the height. The pointers. are moved axially along the drum by a screw t<3> operated by clock mechanism or by the driving motor of the apparatus. The pointer operates the electric contact of the burst apparatus f so that the burst is marked on the screen at the end of the ordered time of flight.

Title: A circuit arrangement for determining the polarity of pulses
Inventor: SCHULZE JOACHIM
IPC: H03K5/01
Filed: 1958-03-19
Abstract: 863,588. Pulse discriminator circuits. ELEKTRONISCHE RECHENMASCHINEN WISSENSCHAFTLICHER INDUSTRIEBETRIEB KARL-MARX-STADT VEB. March 19, 1958, No. 8785/58. Class 40(6) A circuit is caused to respond only to pulses of a given polarity by differentiating the incoming pulses and applying the resulting negative going spikes via a rectifier and storage circuit to the first grid of a multi-grid discharge tube and directly to the second grid of the tube. In this way when a negative spike precedes a positive spike the tube is held cut-off at its first grid so that the positive spike is not passed. The Figure shows a pulse discriminating circuit in which positive and negative-going pulses, for example read-off from a magnetic device, are differentiated by the magnetic head to produce negative and positive spikes in an order dependent upon the polarity of the original pulses. The negative spikes pass rectifier 15 and are stored by the RC circuit 13, 14 and the positive spikes are applied directly to the control grid 11 of tube 9. Thus by selection of the time constant of network 13, 14 positive spikes following after a negative spike do not pass to the output of the tube whereas positive spikes which precede negative spikes pass to the output. Thus it will be seen that the circuit passes positivegoing pulses and rejects negative-going ones. In a modification, Fig. 5 (not shown), the RC circuit is replaced by a damped tuned circuit and operates as a storage device. In a further modification, Fig. 6 (not shown), the tube is a gas discharge tube and controls a relay in its anode circuit.

Title: Improvements in or relating to electrical temperature indicators
IPC: G01K7/24
Filed: 1942-06-26
Abstract: 558,299. Temperature-variable resistances;  resistance measurements. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., WOLFSON, H., AMBROSE, D. M., and SHEPARD, S. C. June 26, 1942, No. 8820. [Class 37] A circuit arrangement for measuring temperature or currents comprises a thermistor and means including a current meter for measuring or indicating the resistance of the element. As shown in Fig. 1, a directly heated thermistor T is connected in series with a battery B, a constant or adjustable resistance R and a direct current instrument M which may be calibrated in terms of temperature. In an alternative arrangement the thermistor forms one arm of a Wheatstone bridge. Alternatively two thermistors, one of negative and one of positive temperature coefficient, may form two arms of the bridge. For measuring currents a thermistor of the indirectly heated type is employed and the current to be measured or a predetermined proportion thereof is passed through the heating coil. Fig. 3 shows a directly heated thermistor for use as a thermometer and particularly for immersion in a liquid. A bead 1, which may be similar to that described in Specification 545,679, is sealed into the tip of a glass tube 2, the bead being mounted on fine wires 7, 8 welded to lead-out conductors 3, 4. The glass is fused closely around the bead 1 to make good thermal contact. Fig. 4 shows another form of thermometer for use in the open air or in a non- reducing gas. A directly heated thermistor bead 1 is mounted on the leads 3, 4 which are supported on a glass base 9. This also carries a wire gauze screen 10 which serves as a mechanical shield without appreciably impeding the circulation of air. Indirectly heated thermistors may be similarly mounted. A pair of directly heated thermistor beads with temperature coefficients of opposite sign may be sealed into the tip of the tube 2, Fig. 3, or one each in a pair of closely adjacent tips, and connected in adjacent arms of a Wheatstone bridge. Similarly two beads may be mounted close together inside the screen 10, Fig. 4. Specification 540,844 also is referred to.
