Abstract: 778,835. Extruding. AKTIEBOLAGET SVENSKA METALLVERKEN. Aug. 12, 1955 [Aug. 25, 1954], No. 23302/55. Class 83 (4). A device for severing and removing the billet surplus from the container of an extrusion press, comprises a cutting means 7, including a punch 11 and stripper plate 8, mounted for movement in the direction of extrusion and in a plane substantially at right angles thereto whereby the cutting means may be moved into registry with the bore of the container 1, be moved into said bore to severe off the billet surplus 17 from the extruded product 16, and together with the surplus be returned out of the container and then moved transversely away from the press. The press has a fixed die 15 mounted on a stationary support 2 and a movable container 1 which, during extrusion, is engaged by a press disc 5 on the press ram 4 and is lowered relatively to the die to extrude the billet between the die and a mandrel 6 thereby forming a tube 16. After extrusion the press ram is withdrawn and the cutting means 7 which are carried at the end of an arm 18 pivoted on a vertical shaft 19, Fig. 4, are moved into alignment with the container. The arm and cutting means are biased upwardly by a spring 20. The cutting means comprises a washer 8 and a punch 11 mounted on the end of a flange 10 which has an upward tubular extension 9 with a slot 12 for passing over the mandrel 6. The washer 8 is supported against the flange 10 by a set of bolts 13 secured to the washer and having compression springs 14 disposed between the flange 10 and the heads of the bolts. For severing the surplus 17, the punch 11 is pressed downwardly by the press ram 4 and thereafter upon retraction of the ram, the cutting device moves upwardly out of the container carrying with it the surplus 17. The arm 18 is then rotated about the shaft 19 to position the washer 8 within a frame 21 whereupon a washer 26 on the end of a pistonrod 25 engages the end of the punch 11 and presses it upwardly out of the surplus 17, Fig. 5 (not shown), thereby detaching the surplus from the punch. The invention may also be employed to horizontal extrusion presses and the various operations may be performed automatically.

Title: Improvements in or relating to finned tubes for heat-exchangers
IPC: F28F1/32
Filed: 1959-11-09
Abstract: 901,321. Finned tubes for heat exchangers. BROWN & CO. Ltd., JOHN, and ROBERTSON, G. D. Feb. 9, 1961 [Nov. 9, 1959], No. 23624/59. Class 64 (3). [Also in Group XXVIII] An aluminium tube for use in a heat exchanger has fins formed by passing the tubes through holes in a number of metal sheets, those parts of the tube between the fins each being encircled by a number of metal collars having nested abutting faces. Preferably, the collars are of materials having different tensile strengths and thus different resistances to radial distortion. In the embodiment shown in Fig. 1, a tube 10 is encircled between adjacent fins 12 by an aluminium or aluminium alloy collar 17 having an outer conical face of 45 degrees angle, said face being embraced by an internal conical face of a collar 20 of mild steel. A washer of aluminium may be disposed between the mild steel collar 20 and the adjoining fin in order to prevent electrolytic corrosion between these parts, Fig 2 (not shown). In a further embodiment, see Fig. 3, each part of the tube between adjacent fins is encircled by a mild steel collar of channel section, the conical inner faces 26 of which converge as they extend towards the web portion 7 and abut the inner faces of a mild steel ring 27. In a further embodiment, Fig. 4, not shown, the channel section ring is replaced by two aluminium rings of triangular crosssection. In these embodiments, the angle of conicity of the abutting faces is in such a relation to the angle of friction that the faces slide over one another when the collars are subjected to radially-directed pressure. In a further embodiment, Fig. 5, each part of the tube between adjacent fins is encircled by an aluminium collar 30 of rectangular cross-section which abuts against each fin and which is itself encircled by a mild steel collar 31 of smaller axial width. The tube 10 is expanded against the encircling collars and fins, which are lightly pressed together, by the passage through the tube of a drift of larger diameter than the internal diameter of the tube. The final assemblage comprises two header tanks 35, 36 between which extend a number of tubes 10 threaded through the fins 12. The main portion of each fin may be slotted and the metal bent out as shown at 42 so that air flowing between the fins is subjected to a scrubbing effect.

Title: Manufacture of sulphuric acid leuco esters of anthraquinone azo-dyestuffs
IPC: C09B9/02
Filed: 1945-09-17
Abstract: Sulphuric acid leuco esters of anthraquinone azo-dyestuffs are manufactured by coupling a diazotized 1 - aminoanthraquinone with an arylide of p-phenylbenzoylacetic acid (in which the aryl radical may be substituted by halogen, alkyl, alkoxy or aroylamino) and converting the product into its sulphuric acid leuco ester or a stable water-soluble salt thereof by a method known to be capable of converting anthraquinone compounds into their sulphuric acid leuco esters, e.g. by the action of a reducing agent capable of reducing the quinone grouping, but not the azo group, and treatment of the leuco compound in the presence of a tertiary base with sulphur trioxide or a substance yielding it.  In examples, the following dyestuffs are treated with chlorosulphonic acid, pyridine and iron powder: (1) 1-aminoanthraquinone --> the 2 : 5-dichloroanilide or 4-chloroanilide of p-phenylbenzoylacetic acid; (2) 1-aminoanthraquinone --> the 2-methoxy-5-methylanilide or 2 : 5-dimethoxyanilide; (3) 1 - aminoanthraquinone --> the 4 - benzoyl - aminoanilide; (4) a mixture of 6- and 7-chloro-1-aminoanthraquinones --> the 2 : 5-dichloroanilide. The products, which are isolated by introducing the reaction mixture into sodium carbonate solution, distilling off the pyridine, filtering and salting out, yield, after development, yellow or reddish-yellow prints.

Title: Planar transmission line amplifier comprising a material having negative differential conductivity
IPC: H04B3/36
Filed: 1975-06-04
Abstract: 1514803 Semi-conductor transmission line COMMUNICATIONS SATELLITE CORP 4 June 1975 [7 Oct 1974] 24031/75 Heading H1K A transmission line amplifier comprises a layer of GaAs, InP, ZnTe, CdTe, mechanically stressed InAs, or Ge at less than 17 K., capable of exhibiting Gunn effect and consisting of substrate and epitaxial portions. The epitaxial portion, the doping concentration of which is n at the surface and decreases abruptly at a depth of 4Á carries at least two ohmic electrode plates defining a gap of width L, where nL < 1 x 10<SP>12</SP> atoms/cm.<SP>2</SP>, opposed ends of the plates constituting input and output ports. A voltage just sufficient to create an electric field of twice the Gunn threshold in the gap is applied between the electrodes and a R.F. input signal applied which propagates normal to the field vector. The line exhibits low noise and a gain dependent on the magnitude but not polarity of the field and proportional to line length. Typically a 10Á layer of GaAs with a surface doping of 10<SP>15</SP> atoms/c.c. is grown on a semi-insulating GaAs substrate, and conductive layers disposed on it 5Á apart, and consisting either of a central conductor between interconnected ground planes or a pair or set of interdigitated pairs defining one or several parallel connected slot lines. In the former construction the central conductor has a width of 7Á to give a line impedance of 50# and is tapered outwards at the input and output ends to form contact bonding pads, the gap to the ground planes being likewise tapered to provide a smooth transmission impedance. Losses in the input and output regions may be reduced by etching away the doped surface of the epitaxial layer in a specified orientation dependent etch, to give smooth changes in thickness along the axis of the line, using a subsequently removed mask of SiO 2 , Nb 2 O 5  or preferably of Ta 2 O 5  formed by oxidizing a photolithographically patterned evaporated Ta layer. Prior to deposition of the conductors, preferably Au-Ge- Ni alloy, by evaporation, the required gaps between them are photoresist masked, then the resist removed with overlying metal and the remaining metal alloyed in. The input signal and D.C. bias (pulsed or continuous) may be supplied to and the output picked off from the slot line structures via coaxial cables the cores and sheaths of which are connected to the respective conductors. Alternatively the input signal is fed into the slot capacitively from a microstrip transmission line the ground plane of which is formed by one of the conductors and the bias via separate conductors. Different methods of locating multiple slot line structures in waveguides are described.
