Abstract: 918,503. Mineral-mining machines. GEWERKSCHAFT EISENHUTTE WESTFALIA. Dec. 4, 1959, No. 41285/59. Class 68 (1). In a mining machine having a plough guided on a face conveyer, the plough and the conveyer being driven by separate motors, the driving motor for the plough is arranged below the discharge end of the conveyer and is coupled by a vertically arranged transmission to the plough driving sprocket which is mounted on the coal face side of the conveyer. Fig. 2 shows a conveyer 12 arranged in front of a coal face 11 in the gallery 10, a plough (not shown) being guided on the conveyer. The discharge end 13 of the conveyer is in the gate road 14 and is supported on a stand 15. The conveyer 12, 13 discharges on to a gate conveyer 16. The motor 19 for driving the face conveyer 12 is on the goaf side of the conveyer which it drives through mitre gearing 20. The motor 22 for driving the plough is arranged beneath the projecting discharge end of the face conveyer. If a second motor is required for the face conveyer, it may be arranged, with the plough motor, under the discharge end of the conveyer.

Abstract: 1,073,135. Semi-conductor devices. MOTOROLA Inc. Oct. 21, 1964 [Nov. 6, 1963], No. 42930/64. Heading H1K. A current limiter comprises a junction gate field-effect structure, having a channel comprising two sequential sections with different electrical characteristics, and having the source and gate regions connected to a common electrode. The device operates as if it comprises two field-effect transistors connected in series and having their gates connected together and connected to the extreme source region, Fig. 2 (not shown). The difference in characteristics of the channel sections ensures that one pinchesoff before the other, and this is achieved by providing one section of the channel with a gate region on both sides while the other section has a gate region on one side only. As shown, Fig. 4, a layer of N-type silicon doped with phosphorus is epitaxially deposited from the vapour phase on a P-type silicon substrate 11. Boron is diffused into the N-type layer, using a silicon dioxide mask, to form annular P<SP>+</SP> type regions 23 and 47. Phosphorus is diffused into the layer to form annular N<SP>+</SP> type source and drain regions 14 and 41. The oxide layer is reformed and parts are removed to expose the drain region 41 and an annular region extending outwardly from the centre of the channel region. Aluminium is vapour deposited over the surface and removed from those areas protected by the oxide. The aluminium is then alloyed to the surface, the outer portion 20 forming ohmic contacts with region 23 and source 14 and forming a regrown P-type gate region 17, while the inner annular portion makes ohmic contact with drain region 41. This drain contact is extended over oxide layer 44 by applying a metal layer 43, and a contact 19 is simultaneously applied to the lower face of the substrate. Contact (19) is bonded to a member (46) which is connected to one lead of a glass envelope, Fig. 6 (not shown), the other lead of which is connected via an S-shaped member to drain contact (43). A plurality of devices may be simultaneously produced in a single wafer.
