Title: Blast furnaces
IPC: C21B7/20
Filed: 1973-09-17
Abstract: 1440086 Blast furnaces DES ANCIENS ETABS PAUL WURTH SA 17 Sept 1973 [20 Sept 1972] 43592/73 Heading F4B Between a material storage hopper 4 of a blast furnace charging installation and the furnace throat 1 there is a pivotally mounted sealing flap valve 7 and a material retaining and metering valve 6. The valve 7 is cooled by a continuous flow of gas introduced through pipes 9 and 11 at a pressure higher than the furnace gases. When the valve 7 is open, the cooling gas passes over and cleans the valves sealing surfaces. Charge material fed to the furnace through the hopper 4 (or through a similar hopper 4<SP>1</SP> and valves 6<SP>1</SP> and 7<SP>1</SP>) is distributed by a shoot 2 which is rotatable and tiltable by a drive mechanism (not shown) in a chamber 5. The chamber is cooled by gas supplied through a pipe 10. The cooling gas may be inert gas and/or cleaned and cooled furance gas. The cooling allows the sealing surfaces of the flap valves 7, 7<SP>1</SP> to be provided by commercially available soft or resilient materials. The cooling gas additionally flows around the shoot 2 and keeps some of the blast furnace dust away from there.

[Also in Division G2] An exposed and developed photo-resist (see Division G2) consisting of a metal (e.g. silver) layer 420 covered in certain areas by dielectric (e.g. arsenic trisulphide) layer 422 is electrolytically etched by placing the resist in enclosure 460 and making the metal layer 420 the anode via electrical contact 466. Contact 471 in metal plate 470 is the cathode and an electrolytic solution (e.g. sodium chloride) is circulated at high velocity and at a pressure between 10 and 50 p.s.i. between the cathode and anode. A direct current of 10 to 20 volts is used and metal layer 420 is partly or completely etched. Alternatively, metal layer 420 may be electro-plated in an electro-plating bath to produce a metallic coating which may be thicker or thinner than layer 422. To prevent plating of layer 422, it may be coated with an oil before electro-plating. Layer 422 may be arsenic tri- or penta-sulphide, arsenic or bismuth.

The invention relates to modification of the facsimile recorder described in the parent Specification, in which a record medium is marked by pressure applied between a first member (a marking bar) and a second member (a helical edge on a rotating drum), the first member being supported for substantially unrestrained movement towards or away from the medium and being controlled electromagnetically to exert a variable pressure on the medium. According to the invention the magnetic circuit of the electromagnet is constructed so as not to include the second member. In a first embodiment, Fig. 1A, the electromagnetic core 23, which carries a winding 20, is formed with a small air gap 25 and has an armature 24 partly closing the air gap which rests freely on the upper surface of core limb 22 with the interposition of anti-frictional devices or a low friction surface coating, such as chromium plating. The marking bar 14, which is preferably a non-magnetic material, such as stainless steel, is fastened to the armature by cementing, brazing or riveting. As an alternative, members 14 and 18 may be made of one piece of magnetic material. The assembly is completed by a non-magnetic cover 16. In a second embodiment, Fig. 3, the armature is formed as a L-shaped member 28 which is in contact with the lower core limb 21 and spaced from the upper core limb 22 by a small air gap 25. The marking bar 14 is attached to the horizontal leg 29 of the armature and rests for free sliding movement on the upper face of core limb 22. Pins 31 freely engaged in slots 30 restrain the bar against accidental dislodgement. In a third embodiment, Fig. 4 (not shown), the marking bar is a separate non-magnetic member which is attached to the armature which comprises an L-shaped member embracing only one core limb. Reference is made to the use of plurality of independent electromagnetic assemblies extending across the width of the record members, and a single electromagnet assembly having a plurality of longitudinally adjacent armatures and marking bars.

Title: Semi-conductor devices
IPC: H01L35/12
Filed: 1960-12-23
Abstract: A photo-electric transducer material comprises a powdered semi-conductor material which is compacted, preferably by vibration, i.e. under low pressure, and sintered to produce a multiplicity of interconnecting neck regions between adjacent granules of the material the neck regions having cross-section dimensions of the same order of magnitude as the average phonon mean free path length in the semi-conductor material.  In the described embodiment a gallium doped polycrystalline P type germanium of specific resistivity 5 X 10-3 ohm/cm is ground to a particle size of 1/10 to 10 microns and placed in a silica glass receptacle under vacuum and shaken to compact it to approximately 63% of the density of the bulk material.  The powder is then heated to 850  DEG C. for one hour to surface sinter the particles. Alternatively a mixture of two or more different semi-conductor materials may be used, e.g. bismuth telluride and bismuth selenide. The semi-conductor material may be doped with, e.g. arsenic which may totally infuse the neck regions while leaving the bulk of the material substantially unchanged, this increases the thermo-electric figure of merit by increasing the charge carrier conductivity of the neck regions of the semi-conductor whilst the bulk of the material is unchanged.
