Title: Improvements in or relating to gas-producers
IPC: C10J3/00
Filed: 1939-07-28
Abstract: 529,436. Gas-producers. WILLANS, K.. and KENNEDY, D. S. July 28, 1939, No. 21976. [Class 55 (i)] In a grateless cross-draught producer, air is supplied under pressure by a fan to a preheater casing e from which it enters the fuel bed through a water-cooled tuyere b, the gas being withdrawn through an outlet pipe l, screened by a grid c', by an injector f fed with air by a pipe h from the casing e. Alternatively, the fan may be connected in the pipe l, the injector creating suction at the outlet of the fan. A pipe n leads the gas to a burner, or to storage, The amount of air used in the injector f is not more, but is preferably less than that required for the combustible mixture, additional air being supplied, if necessary, through a second injector. For starting, a hollow stem g' is screwed into contact with the tuyere b, and a flap r is moved aside so that air enters the tuyere directly, and with an increased flow. The water seal s may be raised or lowered by rotating a nut t<SP>1</SP>, and may be turned to dislodge clinker. The injector may be operated by gas under pressure when it is desired to obtain a producer gas unmixed with air for storage purposes.

Title: Improvements in or relating to gyroscopic apparatus, more especially such as employed in automatic steering devices for craft
IPC: B63H25/04
Filed: 1939-07-28
Abstract: 535,211. Gyroscopic apparatus ; fluidpressure servomotors. SPERRY GYROSCOPE CO., Inc. July 28, 1939, No. 22017. Convention date, July 29, 1938. [Class 97 (iii)] [Also in Group XXIX] In gyroscopic devices for use in automatic steering devices wherein a directional gyroscope is combined with a magnetic compass for maintaining the course the gyroscope mounted to rotate on a horizontal axis is provided with a member rotatable about a vertical axis and means for causing precession of the gyroscope to follow the member whereby a precessional torque is exerted on the gyroscope when the latter wanders and the gyroscope is combined with means controlled from the gyroscope for actuating the steering mechanism. The magnetic compass master controller such as described in Specification 511,724 having magnets 1, 2 is provided with an air nozzle 4 the jet from which passes between shuttered intake ports 7, 8 leading to the gyroscope. On relative displacement of the compass with its base differential air flow through the ports 7, 8 operates a turbine 46 in one direction or the other by means of the jets 15, 16. Rotation of the turbine 10 operates through reduction gearing, a gear wheel 27 journalled above the directional gyroscope. To the gear 27 are secured pick off ports 28, 29 which act in the usual manner to control the rudder servomotor in conjunction with a semicircular cut off plate 30 secured to the vertical outer gimbal ring 31 of the gyroscope. Secured to the gear 27 is a pipe 34, Fig. 1, having a nozzle 35 which directs a continuous stream of air downwardly against the serrated ring 36 secured by brackets to the inner gimbal ring 38 of the rotor 32. When the jet is displaced from the plane of the rotor a torque is exerted about the horizontal axis of the gyroscope causing it to precess back into its aligned position. For course changing the knob 14 is operated, causing a relative displacement of the magnetic elements 1, 2 and the compass base. When quick temporary turns or another method of steering is desired, another turbine 10 is provided and valves 42, 42<SP>1</SP> are manipulated by handle 43 to open one or other of the inlet ports 44 to permit air to enter one or other of the pipes 21, 22 rotating the turbine 10 in the sense desired. The follow-up movement from the rudder is also shown as differentially positioning the ports 28, 29 of the gear 27 from a repeat-back oil pressure cylinder 33 adjacent the relay valve 51 which controls the servocylinder 52 connected to the rudder 53. Specifications 366,058 and 502,473, [Group XXIX], also are referred to.
