Title: Deposition of platinum
Inventor: RHODA RICHARD NOBLE
IPC: C23C18/48
Filed: 1966-10-11
Abstract: A bath for depositing Pt on an active surface, e.g. of Ni, Ni alloy, graphite, Fe, Cu, Mo, Ag, Ta, Ti, or glass, plastic or ceramic first rendered active with a Pt or Pd coating, consists of an aqueous alkaline solution containing 2 to 20 g/l Pt as Pt-IV hydroxide e.g. Na2 Pt(OH)6, 0.1 to 1 g/l hydrazine and sufficient alkali metal hydroxide e.g. NaOH to give a pH of at least 8. Up to 1 mol/l of soluble, compatible N-containing stabilizer may be included, e.g. the sodium salt of E.D.T.A., quinoline, sulphamate ion, preferably 0.5 to 45 g/l ethylamine. For depositing Pt alloys the bath contains at least 0.01 mol/l stabilizer and up to 20% Rh and/or 10% each of Ir and/or Ru by weight of the Pt content.  The hydrazine may be added as hydrate, sulphate or chloride, and may be introduced into the bath on the surface to be coated.  The reduction is autocatalytic.  The invention is applicable to producing catalytically active deposits of Pt on a powder compact of Ni or graphite e.g. a porous graphite disc for a methanol-oxygen fuel cell anode.

Title: Methods of and apparatus for interconnecting electrical components
Inventor: WARMAN BLOOMFIELD JAMES
IPC: H05K13/00
Filed: 1966-10-13
Abstract: 1,140,457. Making electrical circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 29 Sept., 1967 [13 Oct., 1966], No. 45746/66. Headings B3A and B3W. A method of interconnecting electrical components by connecting the components between two common conductors, so that the components are all initially connected in parallel, and subsequently removing unwanted parts of common conductors, includes the step of securing the components between two support strands each made up of a core of flexible relatively inextensible material coated with a heat-softenable coating by heat-sealing the component lead wires into the coating material prior to connecting the component lead wires to the common conductors. The components and a circuit identification pin (7) are initially placed in a jig trolley comprising a rectangular frame (1) mounted on two pairs of wheels and provided with a sear bar (6), which is engaged by dogs 11 on a conveyer chain 10. The sides of the frame are provided with slots into which are fitted the component lead wires so that they project on either side of the frame, Fig. 1 (not shown). On either side of the trolley a pair of plastic-coated strings 20 are sealed to the projecting lead wires between heat-sealing rollers 23 and the " ladder " of linked components is wound on to a spool 25, drawing along the trolley after the dog 11 is disengaged. Any component lead or circuit identification pin not lifted out by the rising ladder is removed from the trolley by a cam 28 and the trolley runs down a slope to be returned to the loading station. From the spool 25 which may merely be a device for lifting the " ladders " from the trolleys, the " ladder " is passed over a welding table where a nickel welding tape is welded to the component leads on either side of each component. Preferably the identification pins are not welded to the tapes. The resulting " bandolier " of components is taken up by a drum which has a slipping drive to stop movement during each welding operation and which may be a traction device to feed the " bandolier " to a punching station. A template 51 corresponding to the desired circuit is positioned under a press block 49 and the component leads are aligned with holes 43 of a female punch member 40. The press block 49 forces certain pins 44 in a male member 45 into the holes 43 thereby severing certain of the leads. Where there are holes 32 in the template, the pins 44 pass therethrough into holes 50 in the press block leaving the leads unsevered.

Abstract: 1280898 Ultrasonic inspection devices G A D GORDON 24 Sept 1970 [26 Sept 1969] 47387/69 Heading H4D Diagnostic apparatus, capable of giving an indication differentiating normal lung tissue from abnormal tissue, comprises means for transmitting periodic pulses of ultrasonic energy and receiving respective resulting trains of reflected pulses of the energy, circuits for deriving rectified signals from the reflected pulse trains and for smoothing said signals, a bi-stable device set at the transmission of each pulse and reset when the amplitude of the respective smoothed signal first drops below a predetermined value, and an indicator measuring the ratio of the set and reset periods of the bi-stable device. This ratio is a measure of the reflected pulse train length and hence of the depth of penetration of the ultrasonic energy into the tissue; abnormal tissue gives a higher ratio than normal tissue.  In the embodiment described. a transmit/ receive transducer is periodically pulsed (waveform A) by a thyratron or SCR pulser to give transmission pulses B which yield reflected wave trains C. The rectified trains D are converted to signals E by a smoothing circuit, whose output is then applied to a Schmitt trigger circuit. The smoothing circuit time constant is long enough to prevent the smoothed signal E amplitude falling below the Schmitt cut-out threshold during brief silent periods between echo signals from the chest wall and those from the lung tissue, but short enough to ensure signal E amplitude falling below said threshold before echo signals are received from the liver or other organ behind the lung. A differentiator derives pulses G from the trailing edges of the Schmitt output pulses F, and the pulses G are used to reset the bi-stable device after its being set by pulses A. The bi-stable device output H is fed via an integrator to a voltmeter.

A silicon-carbide semi-conductor containing a PN junction is made by growing an N-type crystal by recrystallization and/or condensation in a rare-gas atmosphere in the presence of a dopant at 2300-2600‹ C. in a volume bounded by silicon carbide, reducing the temperature of the silicon carbide boundary material to below 2000‹ C., freeing the volume of donor, introducing Al into the volume and continuing growth of the SiC crystal at 200‹ to 300‹ C. below the previous growth temperature. A cylinder 4 of SiC to form the boundary material is made by filling the annular space between a graphite cylinder 1 and a core (2, Fig. 1, not shown) with SiC made by the pyrolysis of CH 3 SiCl 2 H, compressing the powder and sintering it. The cylinders 1 and 4 are closed at each end by plates 5 (Fig. 2, not shown) and heated in a quartz envelope at 2550‹ C. in Ar containing N 2 , to give N-type SiC crystals 8 formed by recrystallization and/or condensation at right angles to the wall of cylinder 4. After cooling, the vessel 1, 4, 5 is placed on a graphite vessel 9 containing Al carbide 10, the crystals 8 being heated to 2250‹ C. and the carbide 10 to 2100‹ C. in Ar. A P-type SiC layer containing Al is thereby deposited epitaxially on the crystals 8. The crystals are sawn into plates, and provided with Pt contacts secured by Au/Ta alloy to give light emitting diodes. In another embodiment, B is used in addition to Al. The light emitted by the diode varies according to the injection current.
