Title: Gas turbine igniter systems
IPC: F02C7/266
Filed: 1975-12-19
Abstract: 1537278 Gas turbine ignition systems; afterburning 19 Dec 1975 [30 Dec 1974] 52080/75 Headings F1G and F1J An igniter in a gas turbine engine combustor is connected to a power source when the turbine shaft deceleration rate reaches a predetermined level following flameout. In the system shown, igniter 25 in an afterburner section is energized when an aircraft reaches a predetermined speed and a given throttle position is selected, at which stage a low voltage DC signal on 54 operates relay coil CR-2 to open CR-2A and close CR-2B to connector augmentor exciter 48 across alternator 43. Igniter 33 in the combustion chamber 27 is connected to a relatively low energy exciter 42 which is connected to a power source 60 via a switch 63 operable by the pilot, this igniter being adapted to operate continuously for long periods without risk of burning out. Igniter 34 in the combustion chamber is connected to a relatively high energy exciter 41 and is adapted to operate for a predetermined period following flameout. While the engine is being run up to a predetermined threshold speed, the contacts CR-1A, CR-1B are set to connect exciter 41 across the alternator, but once the engine reaches the threshold speed AND gate 67 causes coil CR-1 to open CR-1A and close CR-1B to de-energize igniter 34. When, due to flameout, the deceleration rate exceeds a given level for a given period, circuit 69 deactivates circuit 71 and a rate signal is applied to the AND gate to cause coil CR-1 to reset CR-1A and CR-1B to energize igniter 34 for a given period governed by circuit 71. Switch 57 can be closed to short-circuit the alternator and thereby provide for cranking or windmilling of the engine without ignition occurring. A switch 59 can be closed to energize relay CR-5 and close CR-5A to shortcircuit the alternator when effecting a wet prestart.

Title: Method and apparatus for spreading foam compositions
Inventor: ROBERTS THOMAS HENRY
IPC: B29C44/46
Filed: 1967-11-18
Abstract: 1,241,800. Sheet casting. DURIE & MILLER (HOLDINGS) Ltd., and MEADOWS HOLDINGS Ltd. 18 Nov., 1968 [18 Nov., 1967], No. 52566/67. Heading B5A. [Also in Divisions B2 and D1] A pattern of indentations or ridges on the surface of cellular rubber or cellular plastics sheet materials are produced by spraying a foamed latex composition on a flat surface by means of two or more doctor blades which operate singly in succession to spread the foam, the lower edges of the blades being shaped in conformity with the design which it is desired to impart to the surface of the spread foam, the patterns formed by succeeding doctor blades being different or off-set from each other in order to produce an overall irregular pattern and thereafter setting the foam. A backing material may be provided on the flat surface and the foam spread on to it. Apparatus for carrying out the method comprises a spreading surface, two or more doctor blades having their lower edges shaped so as to give the desired pattern on the surface of the spread foam and a mechanism for supporting the several blades and moving them into and away from the spreading position in succession to each other. If two succeeding blades have the same shaped lower edge the blades or designs are staggered so that as each succeeding blade takes up the spreading operation the pattern of indentations or ridges is off-set with reference to the preceding series. Many separate blades may be in the separate position for sewing more different kinds. The lower edges of the blades may have cut out parts of shapes such as V-shaped or semicircular shapes. Alternatively, the lower edges may be provided with protruding portions or may have both notches and protuberances. One or more of the blades may be caused to oscillate to and fro across the width of the spreading zone. As shown in Fig. 1, a roll 1 of a backing material 2 supplies the material to an endless belt conveyer 3 along which it is carried under the doctor blades and a bank of foamed latex 11 to a setting zone 4 whereupon the material on which the latex foam has been spread and set is collected on a roll 5. Two doctor blades 6 and 7 are provided with mechanisms 8 and 9 respectively for moving the blades up and down relatively to the surface of the backing material. The mechanism is such that there is always one or other of the blades in the correct spreading position.

Abstract: 1409095 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 Nov 1972 [25 Nov 1971] 53951/72 Heading H1K In the manufacture of a semi-conductor device involving the introduction of impurities into surface zones of a semi-conductor body to provide at least source and drain regions of an IGFET, the semi-conductor surface is subsequently oxidized through a mask to form a sunken insulating oxide layer covering at least part of at least one surface zone, after which part of the sunken layer above a surface zone is partly or wholly removed, a thinner insulating layer being retained or reformed at the same place. As shown, a surface of an N-type silicon body 1 (which may be an epitaxial layer on a low-resistivity substrate) is masked, e.g. by silicon nitride, and thick sunken oxide portions 10 are grown in exposed areas. Using a fresh mask, source and drain regions 2, 3 and a capacitor electrode region 11 are formed by diffusion or boron-ion implantation; then the exposed surface is oxidized to form a sunken oxide layer 7. The mask is removed, and portions of the layer 7 are removed and thin oxide layers such as 12 are grown in their place; gate insulation 6 may be simultaneously provided. Alternatively the layer 7 may be selectively thinned. Thin oxide layers above source and drain regions 2, 3 and part of electrode region 11 are removed, and gate, source and drain electrodes 5, 8, 9, and capacitor counter-electrode 13 and contact 14 are formed by the vapourdeposition or sputtering of aluminium or molybdenum. A further embodiment (Figs. 6a, 6b, not shown) comprises an integrated capacitor memory of the kind described in Specification 1,273,181, in which each of a series of doped surface zones (61) forms the drain region of one device and the source region of the succeeding device.

Abstract: 1400221 Diluter E ENGELBRECHT 23 Nov 1972 [24 Nov 1971 22 June 1972] 54165/72 Heading G1B [Also in Division F1] In a system for laboratory preparation of a series of liquid dilutions nozzles 77 (of which only one is shown) are disposed in a horizontal row on a slide 92 that can be moved down a column 93 to a stop 94 against the bias of a tensile spring 95 so as to insert the nozzles in a corresponding row of test tubes 80, 81, 82 or 83 on a carriage 75. The nozzles are fed with dilutant from a reservoir 84 by a peristaltic pump P1 driven by an electric motor M24, which can be reversed to draw liquid from the tubes. To mix liquids in the tubes air supplied by an electrically-driven pump P40 is injected through nozzles 79. Notches 91 in the track 90 of the carriage ensure alignment of the tubes with the nozzles. The motor M24 and pump P40 are controlled by a circuit, Fig. 8 (not shown), comprising manually-operated switches (48), 49, 54, warning lamps 67, 68 and an adjustable timing device (87). When stopped the pump prevents liquid leaking from the nozzles 77, which after being charged with the dilutant D, Fig. 9, are inserted first in the tubes 80 containing the liquid L to be diluted. Operation of the switch 54 causes reverse rotation of the pump P1 for a predetermined interval to draw a quantity El of liquid L into each nozzle 77. After transference of the nozzles to the empty tubes 81 the switch 49 is operated to effect forward rotation of the pump and thus ejection of the quantity El of liquid L and an equal quantity Dl of dilutant D from the nozzles, mixing being brought about by simultaneous injection of air through the nozzles 79. Switch 54 is then operated again to withdraw a proportion E2 of the mixture, whereafter the nozzles are transferred to the empty tubes 82 into which the proportion E2 of mixture and an equal quantity D2 of dilutant are injected to produce a second dilution. Further dilutions can be produced in this fashion. The setting of the timing device (87) determines the duration of each operation of the motor M24 and thus the dilution ratio.
