Abstract: 1,253,122. Cooling electric machine rotor windings. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. 27 Feb., 1969 [29 Feb., 1968], No. 10650/69. Addition to 1,215,493. Heading H2A. In an electrical machine, e.g. turbogenerator, liquid cooled rotor winding, each half turn is soldered directly at 53 to the adjacent half turn and has an internal duct 25 or 35 for liquid the two ducts of one turn forming parallel flow ducts connected in the transverse conductor 10 of the end turn region through two-connecting bores 54, 55 to a small supply tube 13 connected to an axially extending projection 49 soldered to the conductor 10 and of axial length 48 and radial thickness 28 each greater than the radial thickness 45 of the conductor 10, the two bores 54, 55 having portions in the conductor 10 and portions in the projection 49 the latter portions being drilled from the transverse conductor side of the projection. This provides a winding similar to that disclosed in the parent Specification but in which the connecting bores do need to be plugged from the side 56 and the tube 13 may be of chrome-nickel steel requiring, remote from the winding, high temperature soldering or welding to the Cu projection 49. The bores 54, 55 may diverge from the projection 49.

Abstract: 1288941 Semi-conductor devices TEXAS INSTRUMENTS Inc 14 Oct 1969 [31 Dec 1968] 50406/69 Heading H1K [Also in Division B6] In the manufacture of a semi-conductor device two or more slots of different depths with linearly convergent sides are formed in one face of a semi-conductor wafer so that the slots become successively exposed as more material is removed from the opposite wafer face. Typically an N- type silicon wafer is first prepared with a 100 orientated surface. After epitaxial deposition of an N+ layer a photoresist mask is applied apertured to expose spaced groups of narrow areas running parallel to intersections of 111 planes with the surface, each group consisting of a number of areas progressively increasing in width. Etching in a specified mixture of water, ethylene diamine and pyrocatechol produces grooves with sides lying in 111 planes and of depths related to etching time and aperture width. After removal of photoresist silicon oxide 26<SP>1</SP> (Fig. 6A) is formed or deposited together with support layer 27<SP>1</SP> of polycrystalline silicon, ceramic or glass. The uncoated surface is lapped down to the required extent, the residual thickness being determined from visual inspection of the number and width of grooves exposed, if desired with the air of a gauging mask. Then an isolated part of the original wafer in which integrated circuit elements are to be formed is divided by further etched grooves and coated with oxide 33<SP>1</SP> and polycrystalline silicon 34<SP>1</SP> as shown in Fig. 11A. If desired depth gauging grooves are again provided for use in the subsequent removal of the original support layer 27<SP>1</SP>. Finally devices are formed in areas such as 21<SP>1</SP> by standard planar techniques. Modifications suggested are deposit of the N+ layer after grooving and of the insulation 26<SP>1</SP> before, and application of the method to mass production of single devices.

The flow restricting device may be a length of capillary tube. The extruder screw may have a section, rotating with the screw and opposite at least the injection port for the liquid blowing agent, wherein the molten thermoplastic is divided into a plurality of streams. This division may be achieved by providing a fluted section in the screw comprising a cylinder having several (at least 3) axial channels formed on its outer surface. It is preferred that the cylinder has a length at least equal to the internal diameter of the extruder barrel, e.g. 3-6 times the diameter. The fluted section may be followed by a turbine section which both shears and further subdivides the mixture. The turbine mixing section preferably comprises a plurality of toothed rotors mounted on the screw to rotate therewith, the teeth of alternate rotors being staggered. After this section there is preferably a further mixing section in which a cylindrical member provided with inlet grooves not extending along the whole length of the member is used. In Fig. 1 a screw rotates in a barrel 1 and the thermoplastic polymer is compressed and melted in a compression section 3 of the screw. The polymer then passes to section 4 of the screw which is fluted having a series of axial grooves (Fig. 2) (not shown) which divides it into a plurality of streams. The first blowing agent is fed in at port 6 and the second injected via a capillary tube 9 at 8. The polymer then passes to turbine mixing section 10 containing a series of spaced toothed rotors (Fig. 3) (not shown) 11, 12, 13, 14 mounted on the screw so that they rotate therewith.

The process for forming the foamed polymer is described (see Division C3), the first blowing agent comprising 20-75% by weight of the thermoplastic and the second up to 10% by weight of the thermoplastic. The polymer may be polyethylene.
