Abstract: 226,778. Lanz, H. [Firm of]. Dec. 24, 1923, [Convention date]. Superheating by gases other than furnace gases; dampers for controlling superheaters. - In a waste heat boiler having a superheating-chamber in the path of the heating gases before they enter the boiler proper, the superheating tubes are placed in an annular space 3 between the casing 2 and an inner wall 6, and dampers are provided to direct the gases wholly or partly through the annular space into the boiler proper. The direct passage of gases to the boiler tubes 1 is regulated by a damper 9. When the damper is closed, the gases pass through an opening in the wall 6 controlled by dampers 10 into and through the annular spaces 3, from which they pass into the boiler tubes through an opening in the wall 6 controlled by dampers 11. At starting, the dampers 10, 11 are closed and the damper 9 opened. In a modification, the gases enter at the bottom of the shell, and upper and lower dampers extend the whole length of the inner wall. The lower set of dampers controls the passage of the gases either into the annular space or directly into the boiler tubes. Specifications 12910/04 and 27761108 are referred to.

Abstract: 1,246,208. Semi-conductor devices. TEKTRONIX Inc. 13 May, 1969 [15 May, 1968], No. 24405/69. Heading H1K. In a JUGFET comprising a channel region located in a uniformly doped layer of the opposite conductivity type supported by a substrate of the same conductivity type as the channel, the part of the uniformly doped layer situated between the channel and the substrate constituting a gate region, a highly doped region of the same conductivity type as the uniformly doped layer is disposed between the gate and the substrate. The channel is provided with source and drain contacts and a gate contact is applied to the uniformly doped layer. Such a gate underlies the channel and may be termed a "bottom-gate". Under increasing reverse bias the depletion layer associated with the bottom gate-channel junction spreads out until it completely fills the uniformly-doped gate region. The provision of the highly doped layer allows the depletion layer to spread further so that the channel may be completely cut off. As shown, Fig. 1, Sb is diffused into part of the surface of a P type Si substrate 10 to form an N<SP>+</SP> type region 14. An N type epitaxial layer 12 doped with P is grown on substrate 10, and B is diffused into an area of the epitaxial layer overlying the buried N<SP>+</SP> type region 14 to form a P- type channel region 16. The portion 18 of the epitaxial layer 12 underlying the channel 16 constitutes the bottom-gate. B is diffused into the channel to form P type source and drain regions 22, 27, P is diffused-in to form N<SP>+</SP> type top-gate region 26 and bottom-gate contact region 27, and B is diffused-in to form an isolating grid 30 surrounding the device and extending completely through the N type epitaxial layer 12. A1 source, drain and gate contacts 32 are applied to the top surface of the device. The exposed surface may be protected with an SiO 2  layer which may also be utilized as a diffusion mask using photoresist and etching techniques. The top-gate region 26 may be omitted. A plurality of FETs together with bipolar transistors may be produced in a single wafer to form an integrated circuit.

These means may comprise an additional secondary winding 3<a> and a rectifier 24 arranged to produce, during every positive half cycle, a potential drop in resistance 23 additional to that produced therein by discharge of condenser 19 and retarding this discharge. Transformer 1 has a drooping voltage characteristic and hence the voltages in secondary windings 3 and 3a increase with decreasing current so that the time for which valve 15 is blocked and hence the welding time interval increases as the welding current decreases and vice versa. In another arrangement, Fig. 3, the winding 3<a> supplies an impedance 25 connected in series with the discharge circuit and shunted by a rectifier 26 so that during every positive half cycle the winding 3<a> produces a voltage drop in 25 additional to that produced therein by the discharging of 19. In a modification the winding 3a is connected in series with a rectifier and a potentiometer resistance an adjustable part of the latter being connected in the discharge circuit. The winding 3<a> may be replaced by a transformer or coil in series with the winding 3 or the discharge circuit may be connected across the welding jaws 4. The arrangements for modifying the voltage of grid 18 may alternatively be used to modify the voltage in the anode circuit of valve 15.
