Title: Improvements in and apparatus for the manufacture and production of hydrogen from gaseous or vaporous hydrocarbons
IPC: C01B3/46
Filed: 1935-07-15
Abstract: <PICT:0458692/III/1> In making hydrogen by reacting hydrocarbonaceous gases or vapours with steam in a periodically-operated chamber having a heat accumulating insertion, e.g. a Cowper apparatus, the hot carbon-black-containing reaction gases, after leaving the insertion, are passed through a flame produced by means of oxygen or air enriched with oxygen, the flame being such that it permeates the whole cross-section of the passage through which the gases flow.  The carbon black is thus completely gasefied.  The flame is made by injecting thin streams of oxygen into a restriction c between two Cowpers a, b.  The insertion may also be a catalyst such as iron oxide, magnesium oxide, or lignite small coke.

Abstract: 1,071,882. Aircraft instruments. SPERRY GYROSCOPE CO. Ltd. May 13, 1965 [May 19, 1964], No. 20559/64. Heading B7W. In an aircraft flight instrument constructed to show the deviation from a predetermined optimum relationship between the acceleration measured along the longitudinal axis of the aircraft and the pitch attitude of said axis to a horizontal plane, whereby a null reading of the instrument, i.e. by maintaining index 35 aligned with the fixed symbol 21 (Fig. 8), defines a desired acceleration/climb flight path. A vertical gyro 30 and a linear accelerometer 31 supply signals # and f, respectively, representing pitch angle and acceleration, to a summing device 34, the signal 0 being multiplied at 33 by a constant b selected for a particular aircraft. The resultant signal # is applied to position the index 35, and the aircraft is flown to maintain # = 0, i.e. with index 35 aligned with symbol 21. A rate-of-pitch signal is summed with X at 37 and an airspeed sensor 38 supplies a signal to a trigger 41 and limiter 42 to inhibit the application of a # signal to index 35 until the desired speed at which rotation of the aircraft should commence has been reached, and thereafter to limit signal # to a value at which the rate of pitch is limited to a safe value. A pointer 39 is provided for indicating air speed error. In a mechanical equivalent of the apparatus described above (Figs. 1 and 9, not shown), the movable index (18) forms an extension from a pendulum bob (16) which detects changes in acceleration, change in pitch being transmitted to the arm carrying the index (18) by a pair of hair springs which are connected also to a pivoted spherical body (11), carrying a horizon line (12) and responsive to a remote gyro (not shown), the indices (18) and (12) being read against a fixed symbol (21). In a still further embodiment (Figs. 2-6 and 11, not shown), which is selfcontained, a horizon bar (12) is mechanically positioned by a gyro vertical (45) and an index (23) denoting acceleration is actuated through a link connection by a bob-weight (16), the separate parts being balanced by springs selected to give optimum take-off indication with indices (12) and (23) in coincidence.
