Title: Hermetically sealing semi-conductor devices
IPC: H01L23/06
Filed: 1960-04-21
Abstract: 883,289. Semi-conductor rectifiers. INTERMETALL GES. FUR METALLURGIE UND ELEKTRONIK. April 21, 1960 [Aug. 22, 1959], No. 14036/60. Class 37. In a method of hermetically sealing a semiconductor device all the soldering operation incidental to the sealing, except one, are performed before etching the semi-conductor, and the final soldering is between parts so shaped that vapours produced during the soldering are prevented from reaching the semi-conductor surface. The connecting lead to the semiconductor is sealed to the casing by a coldwelding process. In Fig. 2, a semi conductor wafer 6 is attached to two pot-shaped members 7 and 8 by soldering, the assembly then being etched. A stranded tinned copper conductor 4 is attached to part 8 by compressing the sides of the pot on the wire 4. The assembly is then secured to the base member 1 by solder layer 9, vapour produced during this soldering operation being prevented from reaching the surface of semiconductor layer 6 owing to the close fit of the sides of pot 7 in annular groove 2. The connecting lead 4 is passed through copper tube 10, Fig. 1, of the metal to glass/ceramic gland 5, after which the metal rim 3 is pressed in to seal the gland to the base 1 via layer 11 of a soft metal, e.g. tin or a lead silver alloy. The casing may then be evacuated, and if required, gas filled, through tube 10, after which the tube is compressed on to wire 4 to form an air-tight seal.

IPC: D06P3/52
Filed: 1953-05-20
Abstract: Filaments, films and the like of aromatic linear polyesters are treated with the vapour of sulphuric acid, sulphur trioxide or chlorsulphonic acid.  The treatment renders the material more hydrophilic, whereby its dyeing properties are improved and it becomes less liable to accumulate electrostatic charges.  The treated material is particularly susceptible to basic dyes in aqueous solution, such as Malachite Green, Methylene Blue and Bismark Brown, and can also be dyed more readily with mordant dyes such as aluminium, iron and chromium mordant dyes.  In an example a woven fabric of material sold under the Registered Trade Mark " Terylene " is exposed to the vapour of fuming sulphuric acid at a concentration equivalent to 0.11 gms. sulphur trioxide per litre for 30 secs. at 20-21 DEG  C. and washed.  After immersion in a 0.5 per cent aqueous solution of Methylene Blue for 10 mins. at 20 DEG  C., the material is dyed deep blue, fast to boiling water. Further examples describe different concentrations of sulphur trioxide and different times and temperatures, but conditions preferred are 0.01 to 0.5 gms. sulphur trioxide per litre for 1-60 secs. at 15-25 DEG  C.ALSO:Filaments and the like of aromatic linear polyesters are treated with the vapour of sulphuric acid, sulphur trioxide or chlorsulphonic acid.

Abstract: 615,895. Rope strainers. MEYER, R. L. June 6, 1945, No. 14223. Convention date, May 25, 1944. [Class 45] [Also in Group XXV] A cargo-lash comprises a rope connected at one end to a buckle, the rope being then bent to form a loop, passed through the buckle, bent to form a second loop and passed again through the buckle, lever-operated gripping means being provided on the buckle to grip the rope portions passing therethrough. The device is particularly applicable to the securing of boxes, crates, &c., on air liners, ships and vehicles and, as shown in Fig. 3, comprises two snap-hooks 61, 62, to anchor a rope 50 to the vehicle, and a buckle 30 for straining and securing the rope. One end of the rope is secured by a knot 55 to a link 51 pivoted to a straining-lever 35, in turn pivoted to the body of the buckle 30. From the knot, the rope passes through an eye on snap-hook 62, through the buckle and an eye on snap-hook 61, and back through the buckle. In use, after the buckle has been adjusted to a convenient distance from the snap-hook 62, the slack in the rope is taken up by pulling on the free end 59. Now, upon the clockwise rotation of the straining-lever 35, the two bights of the rope that pass through the buckle are clamped and, at the same time, the loop of rope between the buckle and snaphook 62 is shortened to stress the rope. The straining-lever may be held in this operative position by a U-shaped member 37 pivoted to the body of the buckle, which is U-shaped in section to accommodate the rope. The straining- lever is integral with a cam 34, Fig. 4, and is rotatable about a pin 36 extending through the body of the buckle. The cam co-operates with a U-shaped clamping member 41 slidable on the pin 36 to compress the bights of rope against the base 32 of the buckle, the horizontal limb of the member being serrated to increase its clamping action. Modified clamping devices. The clamping member 4, Fig. 4, may be dispensed with, in which case the upper face of the base of the buckle body is serrated or is formed with two arcuate channels 47, Fig. 13, to receive the rope. Alternatively, the clamping member may be retained and itself provided with channels 48, Fig. 14, or the clamping member may be replaced by a floating plate 63, Fig. 17, one end of which is restrained by a pin 67 movable in slots in the body of the buckle. In this last embodiment, both the plate and the buckle body are serrated.

Abstract: 1402198 Photographic direct-positive silver salt emulsion AGFA-GEVAERT AG 27 March 1973 [1 April 1972] 14538/73 Heading G2C A direct-positive photographic silver salt emulsion comprises grains of a silver salt which have been superficially fogged to produce fog which can be developed without exposure and then covered with a protective silver salt layer so that the fog nuclei are no longer at the surface of the grains. The protective layer may be 5 to 100 lattice planes thick. The silver salt of the grains may be the same as or different from the silver salt of the protective layer. The silver salt may be silver bromide which may contain up to 10 moles per cent of silver iodide. The grains may have been chemically fogged with a reducing agent in the presence of a gold compound or a compound of another metal which is more electro-positive than silver, before the protective layer is applied. The emulsion may be coated as a layer and be imagewise exposed so that the developable fog in the grains is imagewise destroyed and developed in a photographic developer containing a solvent for the silver salt of the protective layer. The solvent may be sulphites, thiocyanates, thiosulphates or triethanolamine. The emulsion may have at least three layers, namely the core which is chemically ripened on the surface, the shell which has a developable fog on the surface, and the outer protective layer which envelopes and protects the fogged silver halide shell. The emulsion has excellent stability regarding its sensitivity and maximum density.

Abstract: 1,080,013. Fluid-pressure servomotor systems. DE HAVILLAND AIRCRAFT CO. Ltd. May 6, 1964 [May 10, 1963], No. 14663/63. Heading G3P. [Also in Division G1] Mass flow of fluid through a conduit 1 is controlled by apparatus comprising a restriction 2 and a valve 19 opened by a spring 20 and closed by pressure in a conduit 18. Pressure upstream of the restriction 2 is communicated through a subsidiary restriction 30 to a chamber on one side of a diaphragm 4 and pressure downstream of the restriction 2, or at the throat of a Venturi in place of the restriction, passes to the other side of the diaphragm 4. The diaphragm will move relatively to an outlet 8 until the pressures on its opposite sides are equal so that the pressure drops across the restrictions 2, 30 are equal. The pressure in a conduit 9, discharging to atmosphere through a restriction 10, will then be proportional to the mass flow, provided atmospheric pressure remains constant. To make the apparatus independent of atmospheric pressure the restriction 10 may be "choked". The pressure in the conduit 18 is determined by a beam 14 controlling a vent 15 and actuated by a bellows 12 subject to the pressure in the conduit 9. In a modification, the diaphragm 4 is dispensed with, a restricted outlet to atmosphere from a conduit between the restriction 30 and the bellows 12 is controlled by a pressure-reducing valve, and a second bellows acting on the beam 14 in opposition to the bellows 12 is subject to the pressure downstream of the restriction 2.
