Abstract: 1,123,655. Sheet metal exterior wall cladding. ALSCO Inc. 5 May, 1967, No. 20948/67. Heading E1W. Dielectric coated sheet metal exterior wall panels 10 are each formed along one edge 11 with a channel and along the opposite edge 12 with a tongue so that when the tongue of a panel engages the channel of an adjacent similar panel an overlapping, interlocking joint is formed therebetween, a portion within the channel being shaped to contact a portion of the received tongue of the adjacent panel, these portions in contact being free of dielectric coating material whereby electrical connection is established between the panels on a line 15 along their length, the line 15 of electric contact being isolated from exterior influences by a line 17 of dielectric contact between zones situated between the dielectric free portions and the exterior dielectric coated face 8 of each panel. A line of dielectric contact may also be established along a line 16. The panels may be mounted so that their edges extend vertically, or horizontally, in which case the interlocking joint is above the dielectric contact line 15, as shown in Fig. 3, with the channel opening downwardly. One panel of an array of panels may be electrically earthed.

Patent GB-829640-A (GB)
Title: Improvements relating to the manufacture of alloy strip
Inventor: WORN DAVID KENNETH
IPC: B22F3/18
Filed: 1955-07-20
Abstract: Strip, or thin shaped pieces are made of an alloy that is inherently brittle at room temperature by compacting a mixture of metal powders corresponding to the composition of the alloy into a strip, sintering at a temperature which will relieve internal stresses but not be high enough to render the alloy homogeneous, cold rolling in one or more stages to the final thickness desired then carrying out any desired shaping operations, and finally homogenizing the strip or tin shaped pieces formed therefrom by further heating.  Annealing steps may be interposed between the cold rolling stages, while the final homogenizing temperature should be higher than that used for sintering.  The process is particularly applicable to binary Fe-Co alloys, but also to permanent magnet alloys of Ni-Fe-Al with or without Co.  In an example Co powder size 5m  obtained from the oxide and Fe powder size about 3m  and of irregular shape obtained from the carbonyl are ball-milled to mix, and then heated in hydrogen at 400-450 DEG C. for 4 hours to improve their flowability and produce a light sintering.  It is then crushed to between -100 and +60 mesh to the linear inch; compacted into strip 1 inch wide and 0.004 inch thick between rolls; sintered at 1150 DEG C. in hydrogen for 10-15 seconds; cold rolled in 3 stages to a thickness of 0.002 inch with inter-stage anneals at 1150 DEG C. in hydrogen for 10-30 seconds if desired; and finally homogenized in hydrogen at 1200 DEG C. for 10 minutes.  In a further example powdered alloy of 70% Ni, 30% Al passing a 300 mesh, fibrous powdered Fe (from its carbonyl), and Co particles of 5m  (from its oxide) were mixed to fine a resultant composition 12% Al, 28% Ni, 5% Co, remainder Fe, and rolled into strip 0.024 inch thick.  This was sintered in hydrogen for 30 minutes at 700 DEG C. in a box sealed with a 50% alumina, 50% Ti powder mixture as a "getter", then cold rolled to 0.013 inch, annealed under the same conditions as those in which it was sintered, cold rolled to a final thickness of 0.009 inch, and finally (together with punched discs therefrom) homogenized by heating for 4 hours in hydrogen at 1300 DEG C., then cooled in 15 minutes to room temperature.  Other treatable alloys referred to are Fe with 2-11% Si, and Fe with 5-15% Al.

Abstract: 1311604 Transistor amplifying and gating circuits OFFICE DE RADIO DIFFUSIONTELEVISION FRANCAISE 19 April 1971 [6 Feb 1970] 21299/71 Heading H3T An amplifier output stage T5 is connected by a feedback impedance R11 to an input stage T2, T3, and a current generating transistor T12 in series with R11 has at least one diodeconnected biasing and temperature-compensating transistor T13(14) and has means such as a variable resistor 15 or variable voltage applied to it, which adjusts T12 current in order to zero the amplifier output 6 when the input 1 is zero. For video signals, R16 is variable to adjust the pass band, and R8, R11 constitute L.F. feedback while C9 gives H.F. feedback. The voltage drop across R11 is set to 2V BE  to compensate for T2, T3 emitter-base drops. The output 7 is driven by T5 and also by T6, itself driven by T5. The drive circuit for T6 may include two further transistors (109, 110, Fig. 7, not shown) and two outputs (107, 107<SP>1</SP>) may be used. Video circuits employing the Fig. 1 circuit are disclosed (Figs. 8, 9, 10, not shown), and they include other circuits such as a differential amplifier, Fig. 3 (not shown); a bias circuit (Fig. 2, not shown) to drive the Fig. 1 circuit and having a capacitor whose plates (21, 22) are connected between a signal source and the input 1 of Fig. 1, and also having a L.F. feedback between 7 and 1; and gating circuits (Figs. 5, 6, not shown).
