Title: Improvements in and relating to Level or Inclination Indicators.
IPC: G01C19/44
Filed: 1918-01-24
Abstract: 130,095. British Thomson - Houston Co., and Clinker, R. C. Jan. 24, 1918. Gyroscopic speed indicators.-Apparatus for indicating the deviation of an aircraft from the level and the amount of the deviation comprises a member, consisting of a pair of oppositely-driven gyroscopes, which is deflected through an angle proportional to the angular velocity of the turning movement, together with a device for integrating the movement with regard to time, thereby giving a reading proportional to the angle turned through. A frame secured to the body 2<a> of the aircraft has mounted therein two similar oppositely-driven gyroscopes 2, 3, the precessional axes of which are connected by toothed sectors 6, 7. A flat spiral spring 8 tends to keep the spinning axes of the gyroscopes normally at right-angles to the axis round which the tilting movement is to be measured. In use, should the nose of the aircraft dip, the precessional movement against the spring 8 is communicated by the shaft 12 of one of the gyroscopes to the integrating-device 13, this portion of the apparatus being shown in plan view in Fig. 1. Mounted on the shaft 12 are two toothed sectors 14 driving toothed regulating arms 16 of two clockworks, the arms carrying pinions 20 engaging teeth formed on the edges of caps 17. Mounted on the shafts of the pinions 20 are pinions 21, between which and rollers 22 carried by the arms 16 the balance springs of the clocks are gripped. The resultant altered rates of the clocks are communicated through differential gearing to a pointer 25 which gives an indication of the angle of dip of the aircraft. Should it be desired to indicate the movement about an axis at rightangles, a second apparatus is employed and correspondingly situated. The clockwork integrator may be replaced by a suitable electric device.

Filed: 1927-01-18
Abstract: 285,225. Nixon, E. G., and Lamson Paragon Supply Co., Ltd. Jan. 18, 1927. Bookbinding.-In making manifold sales books or blocks of the kind wherein original and duplicate leaves attached together at one edge are bound at the opposite edge of the duplicate sheet to form a stub to which a carbon or like sheet is attached, two superposed webs 1, 2 of different widths are united by adhesive 3 or other means along their median line to form two portions which are subsequently cut transversely into leaves of the required height. The webs are superposed symmetrically so that the web 1 projects an equal amount on both sides of the web 2 to form the binding stubs, and the separation of the duplicate sheet from the stub is facilitated by providing lines of perforatiors 5, 6. The detachment of the original from the duplicate may be facilitated by lines of perforations 7, 8 on either side of the median line, or the adhesive may be applied in a series of spots or a broken line so that the sheets can be torn apart easily. Papers of different colour and quality may be used for the original and duplicate sheets, and more than two webs may be superposed and secured along their median line to provide sets of triplicate &c. leaves. In assembling books or pads a series of webs after cutting along their median line, are preferably assembled in a pile of the desired thickness and bound along their stubs to form a long book which is then cut transversely into a number of smaller books.

Abstract: 1,049,367. Pulse-generating circuit; cathoderay oscilloscopes. R. KELLER. Jan. 13, 1965 [Feb. 7, 1964], No. 1531/65. Headings H3P and H4T. [Also in Division G1] In a method of measuring high voltage signals, distortionless attenuation is provided by a network which first differentiates the signal and then integrates it to restore it to its original shape. The attenuator output is fed to a measuring instrument, e.g. an oscilloscope. Differentiation and integration may be performed by passive C.R. networks, Fig. 1 (not shown), or, in order to reduce the distortion due to discharge of the integrator capacitor, the integrator may be of the " bootstrap " type employing a transistor amplifier, Figs. 4, 5 (not shown). The passive elements may be arranged in probe unit, Fig. 2 (not shown), containing a compensating resistor in series with the differentiation capacitor coupled by a coaxial cable to a further unit, Fig. 3 (not shown), which includes the differentiator resistor R1 arranged coaxially about the integrator resistor R2. Measurement of the output of a pulse generator, Fig. 7, the discharge of a cable, Fig. 9 (not shown), and arc voltage of a spark gap, Fig. 11 (not shown), are referred to. In the last mentioned compensation for the self-induction of the spark gap is provided by connecting the gap to the probe via a coupling loop. The pulse generator, Fig. 7, comprises a capacitor charged to 70 KV and connected to a load of 100 by means of a spark gap T 1 . After a delay of 14Á sec. a spark gap T 2  shortcircuits the capacitor, the short-circuit current being limited by a 4# resistor.
