Title: Improvements in or relating to mosaic electrodes for electronic scanning devices
IPC: H01J29/38
Filed: 1937-09-09
Abstract: 502,024. Cathode - ray tubes. HEIMANN, W. Sept. 9, 1937, No. 24540. Convention date, Sept. 10, 1936. Drawings to Specification. [Class 39 (i)] In a mosaic screen consisting of photoelectric elements arranged in capacitative relationship to a common electrode, the photoelectric or secondary emission sensitivity of the elements varies over the surface of the screen. Alternatively the distribution of the elements varies over the screen. In an example described, the variation consists in an increase of the photo-electric sensitivity and a decrease of the secondary emission sensitivity from the centre of the screen outwards in one or both of two perpendicular directions. The variation is obtained by oxidizing a silver plate which carries the globules of photo-electric substances to a variable degree at different points. The variation may be from one edge of the screen to the other in the direction of movement of the cathode beam in its scanning operation.

The breaker plate 32 of an automatic advance and retard mechanism 33 is moved by a collar 27 on a throttle operating shaft 25 to a retarded position, e. g. 5‹ after T. D. C. when the foot pedal 41 is released. When the pedal is depressed the plate 32 first follows up the collar 27 to advance the spark, e.g. to 8‹ to 12‹ before T. D.

After collar 26 contacts collar 24 on the throttle operating lever to open the throttle valve, the collar 27 frees the breaker plate for automatic control by the usual vacuum and centrifugal mechanisms. The pedal 41 is returned to its release position by a spring 61 which is stronger than a spring urging plate 32 in the advance direction.
Patent GB-421297-A (GB)
Title: Method for the production of finely divided lead or lead oxide
IPC: B22F9/08
Filed: 1933-09-07
Abstract: <PICT:0421297/III/1> Finely divided lead is produced by disintegrating molten lead in a rotating chamber provided with disintegrating means such as ribs or stirrers, the lead being maintained at the necessary temperature entirely by means of hot gases which act directly on the lead and which contain no component which will react with the lead.  The finely divided lead may subsequently be oxidized in a separate chamber, the heat of oxidation being utilized to melt the lead which is being supplied to the disintegrating chamber.  The hot gases from a coke fire 1 pass into a rotating chamber 4 in which molten lead is disintegrated, the gases supplying all the heat necessary to maintain the lead at the required temperature, about 1 DEG  C. above the melting point.  The finely divided lead is carried by the gases into a rotary oxidizing chamber 7, air being drawn in through an adjustable opening 6.  Steel cones may be provided in the chamber 7 to grind the precipitated lead oxide which is subsequently removed at 13.  Waste gases are drawn off by a suction device through a channel 12 to a purifying plant.  A vessel 8 is provided in the chamber 7 to which lead is fed through openings 10, 11, the lead being melted in the vessel 8 by the heat of oxidation of the finely divided lead in the chamber 7 and passing from the vessel 8 through the tube 9 into the disintegrating chamber 4.  The Specification as open to inspection under Sect. 91 refers to the production of lead compounds in general and describes a disintegrating drum in which the lead is raised up during the rotation and allowed to fall on to a plurality of conical surfaces mounted on a shaft rotating a high speed.  This subject-matter does not appear in the Specification as accepted.

A toy railway vehicle coupling comprises a coupling hook engageable with a coupling hoop and has means for holding the hook in an uncoupled raised position until two vehicles provided with the device are pushed against one another with a predetermined coupling pressure. A hook c has a downwardly extending projection p which engages the rear portion of a hoop d and prevents the hook c from swinging down. The hoop has a neck portion t which is longitudinally slidable on a support e and the hoop is normally urged away from the vehicle by a spring r which at one end engages a projection q on the hoop and at the other end is retained in an aperture s in the support e. On bringing two vehicles together for coupling, both hoops d are pressed back and the projections p clear the hoop portions thus allowing the hooks c to swing down to their coupling positions. A control strip in the track may be used for raising the hook to the uncoupled position (Fig. 3, not shown) and a part O on the hook permits uncoupling by hand.
