Abstract: 1,227,617. Flasks. RHONGLASWERK DERMBACH VEB. 19 Nov., 1968, No. 54787/68. Heading B8D. [Also in Division F4] A vacuum or other thermally insulating flask has an external storage container in which items for addition to the contents of the flask are retained, at least partly, by the placing of a top cap on the flask. As illustrated, the storage container comprises two vertical strips 6 which are joined at their bottom ends by a crosspiece 10. The outer side of the container is closed by a spoon 9 which engages a projection 11 on the crosspiece 10 and whose handle engages two slots at the top of the strips 6, Figs. 2-4 (not shown). The top of the container is closed by the handle 5 of a cup 4 which serves to close the flask. The container may house sugar lumps 12 and a milk container 7 which has flanges engaging the top of the strips 6. A saucer 14 is detachably secured to the bottom of the flask.

Abstract: 1,227,964. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 2 July, 1968 [2 Aug., 1967], No. 31504/68. Heading H1K. A semi-conductor device is formed within a zone of one conductivity type isolated from a substrate body of the opposite type by an intrinsic layer. An isolated transistor may be made by epitaxially depositing N-silicon to a depth of 15 on a P+ wafer, diffusing through holes in oxide masking to form a P + ring penetrating the epitaxial layer and an N+ surface layer within the ring, removing the oxide, epitaxially depositing an N- layer overall and then remasking and diffusing further impurities to form an inner N+ ring penetrating to the N + layer, which forms the collector zone, to extend the P+ ring to the surface and to form the P-type base region. Finally an N+ emitter zone and collector contact region are diffused in and a layer of gold evaporated on the back face of the substrate and diffused in to convert the N-region into intrinsic material to provide the isolation and possibly an I-region between the base and collector zones. In an alternative method the gold diffusion is rendered unnecessary by depositing intrinsic rather than N- material. In another method pockets are etched in the first N- layer, lined with N+ material and filled with N material and then the device structure and the P + ring are formed and the N- material converted to intrinsic by diffusion steps. A third possibility is to form N+ inclusions in the first N- layer, deposit further N material overall, etch a channel in it down to the N- layer, fill it with N- material and then form the transistor zones and N + and P + rings and convert the N- material as before.

Abstract: 1,231,129. Fuel elements. BELGONUCLEAIRE S.A. 1 Dec., 1969 [29 Nov., 1968], No. 58614/69. Heading G6C. A porous plug for a nuclear fuel rod comprises refractory material including metallic crystals having a preferential orientation of its metallic crystals providing selective porosity and resulting from plastic deformation of the material. Crystal orientation of metallic sheet or sections may be obtained by well known operations, e.g. drawing, laminating, extrusion or a combination of one or more of these operations. The fuel rod shown in Fig. 2 has a jacket 1 filled with fuel pellets 2 and provided with a plug 3 fixed on the end of jacket 1 by a weld 4. The plug 3, made of a disc cut from a drawn rod, has porous passages represented by the arrows 5 through which fission product gases are released. A conventional filter 6 is placed between the fuel and the plug. The rod from which the disc is cut is made from Fe, Ni and Cr powders which are mixed and compacted using a relatively low pressure, e.g. about 1.5 t./cm.<SP>2</SP> to form a block of stainless steel. The block is then enclosed in a protective envelope to protect it from oxidation and converted into a rod by drawing.

Abstract: 1,232,814. Clutch/brake combination control; machinery safety devices. C. C. BROWN. 17 March, 1969 [16 March, 1968], No. 12864/68. Headings F2L and F2J. In an eccentric power press the eccentric 4 is driven through gear-wheels 3 and 5 from a shaft 1, the shaft 1 being clutched at 2 to a flywheel driven by an electric motor and, by axially moving the shaft, being braked by discs 7, 8, the clutch and brake being controlled so that engagement/disengagement of the clutch automatically releases/applies the brake, respectively. As shown in Fig. 2, the clutch is held disengaged by springs 14 acting on a rod 13 passing through the shaft 1. This disengaging force moves the shaft 1 and a brake disc 7 rigidly mounted thereon to the left, e.g. by 0À005 inch, to engage a fixed brake disc 8 and hence apply the brake. When fluid, hydraulic or pneumatic, is applied to the left-hand end of a piston 12, the rod 13 is moved to the right to engage the clutch and release the brake. A disc 15, Fig. 3A, rotates with the eccentric and is interconnected with a ram guard 23 for safety. The guard 23 is mounted on a lever 18 and, on lowering the guard manually, a roller 20 on the lever moves out of a slot 16 on the disc 15 and a gate 28 on the lever contacts a latch 25a on a link 25 to move the link down to open a valve 27 which causes a plunger (29), Fig. 3B (not shown), to extend out above lever 18 to prevent raising of the guard, and also permits fluid to flow to cylinder 10 to engage the clutch. The eccentric, and disc 15, then rotate through one revolution and a peg 17 on the disc strikes a plate 30 on the link 25 freeing the latch 25a and allowing the link 25 to move back up to close valve 27 which withdraws plunger (29) and releases the clutch. The guard is then raised by a spring 21. The spring and plunger may be replaced by a double-acting pneumatic piston and cylinder acting on the lever 18. An air cylinder 32 may be provided and supplied continuously with air to provide fail safe characteristics. It raises the link 25 should the return spring of valve 27 fail, and it moves latch 25a out of the path of the gate 28 should the air supply fail, so preventing the falling gate from closing valve 27.

A cooling assembly for a blast furnace comprises vertical and horizontal pipe loop sections 2, 3 respectively through which water or steam is circulated. The pipe loops are embedded in silicon carbide refractory 5, to which an inner fire clay brick layer 6 may be secured. During operation the latter wears away to be replaced by a blast furnace slag layer 7 formed in situ. Normally coolant only flows through pipe loops 2, but if leakage into the lining should occur, it is detected by temperature sensing units 4, and the reserve pipe loops 3 for that section of the furnace are used instead. Coolant may also be circulated through both sets of pipe loops 2, 3 under the control of the temperature sensing units 4, to increase the build up of the slag layer 7. An insulating refractory layer (not shown) may be provided between the shell 1 and the silicon carbide refractory 5.
