Abstract: 1,253,093. Radiation measurement of coating. UNITED STATES STEEL CORP. Feb. 4, 1969 [Feb. 9, 1968], No.5850/69. Heading G1A. In an apparatus for determining a characteristic of a workpiece e.g. measuring the thickness of a coating on a moving metal strip S by detecting the energy in a beam of radiation returned from the strip when a beam of radiant energy is directed on it, the source 14 Fig.2 and the detector 20 are mounted in sealed fashion across openings 12, 18 in a container 6 wherein the temperature is maintained substantially constant by a flow of clean dry air through a pipe 32 through a conduit 26 carrying electrical leads and providing clearance for air exhaust. If required additional cooling is provided by water in pipes 40. Source 14 may be an x-ray device and the container may be mounted with the openings 12, 18 adjacent the strip in the vicinity of a roller. A particular application described is in the vacuum deposition of aluminium on the strip, one or more containers 6 being mounted inside or outside the vacuum chamber. A number of containers may be mounted across the width of the strip or at different points in the processing, and their readings may be separately recorded.

Abstract: 1,257,920. Polymer compositions. FURUKAWA ELECTRIC CO. Ltd. 31 Dec., 1968 [22 Jan., 1968], No. 61928/68. Headings C3B, C3P, C3R and C3T. [Also in Division H1] Synthetic resin compositions for high voltage insulation comprise 0À01 to 10 weight per cent of an additive selected from dihydrocarbyl or polymethylene thiuram compounds or metal dihydrocarbyl or polymethylene dithiocarbamates wherein the hydrocarbyl groups are alkyl, alkenyl or aryl; metal alkyl-, aryl- or alkenyl xanthates; mercapto imidazoline compounds; aldehyde/aniline condensates; and phenols; the insulation having been subjected to such a voltage gradient as will cause partial discharges at any voids or like defects in the insulation, thus converting such parts of the additive as have bled on to internal surfaces of the voids or like defects into substances of surface resistivity below 10<SP>12</SP> ohms.

Abstract: 1,258,608. Helicopter rotor spar pressuresensing system. UNITED AIRCRAFT CORP. 16 Oct., 1969 [5 March, 1969], No. 50831/69. Heading B7W. A blade of a rotor of a helicopter is provided with a fluid-tight D-spar upon a rear wall 31b of which is mounted a pressure transducer 21 comprising a bellows 21a which is filled with air at the same pressure as that in the spar, and should a crack develop in the spar the pressure in the spar will fall so that the bellows 21a will expand to open a switch 11. The switches 11- 16 of all the blades in the rotor are connected in series across rotor winding 49a of rotary transformer 48 which is situated at the base of rotor shaft 42. Stator winding 50a of the transformer is shunted by a capacitor 64 and these, together with resistors 66 and 67 form a potentialdividing circuit connected across A.C. source 60. When all the switches 11-16 are closed winding 49a is short-circuited and the impedance of winding 50a is therefore low, so that there is a substantial voltage across resistor 67. This is rectified by full-phase rectifier 70 and applied via Zener diode 76 to the base of transistor 80, rendering the transistor conductive, so that green indicator lamp 82 is lit by D.C. source 62. Should a crack develop in any of the rotor blades the winding 49a will be open-circuited, the impedance of the winding 50a will be high and hence the voltage across the resistor 67 will be so low that the voltage output from the rectifier 70 will be lower than the voltage of the Zener diode 76. Transistor 80 will become non- conductive, and the potential at its collector will rise, rendering transistor 86 conductive. Thus the green light 82 will be extinguished and red lights 88 and 89 lit. Alternatively the transducer 21 may be such that expansion of the bellows 21a closes switch (11a, Fig. 6, not shown), the switches of all the rotor blades being connected in parallel across the winding 49a, so that when all the blades are pressurized the impedance of the winding 50a will be high; thus a substantial voltage can be tapped off the winding, actuating relay 79 in the manner illustrated (Fig. 7) to light the green light 82; a crack in any of the blades will cause the winding 49a to be short-circuited, lowering the impedance of winding 50a and hence the voltage applied to the coil of relay 79. Thus the green light 82 will be extinguished and the red lights 88 and 89 lit. In each embodiment a switch 90 is provided in series with the A.C. source 60 for testing the apparatus.

Abstract: 1,258,642. Embossing. SUD-AVIATION SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. 9 July, 1969 [15 July, 1968], No. 34512/69. Heading B3Q. The invention comprises a method and an instrument for marking metals in which character-bearing elements are impelled by a compressed fluid singly and successively into engagement with the material to be marked, each element after the first being impelled only after the previous one has substantially completed its travel. Character bearing elements 15a, 15b &c. are mounted in channels 14a, 14b in a marking instrument, Fig. 1. Latching means comprising slide pistons 45a, 45b &c. hold the elements prior to impelling by means of rods 47, at the opposite end of the latching means rods 48 extend into engagement with a reset plate 42 after the operation of the instrument. The first means 45a comprises a solid body 52, the rest are composed of two solid pistons 49, 50, the gap between them serving to connect channels 26b &c. with channels 35a. On admitting compressed fluid to the channel 25, all the elements are pressurized against their latches 47. The first latch is released by fluid acting against the piston 52, thus removing its attached latch 47 from element 15a causing the latter to be impelled into marking engagement with the material. At the end of its travel fluid enters port 19, passes along channel 18b and acts on the piston 49 of latching means 45b to release element 15b simultaneously cutting off the fluid supply to element 15a. The same sequence actuates the other elements 15c &c. A member 16 prevents the members from leaving the instrument, and they are reset by inserting a comb into the instrument, the teeth of which push the elements up their respective channels to be engaged by latches 47 on pressing of the reset plate 42.

The apparatus comprises a light source 1 producing a beam which is focused by lenses 3a, 3b upon the aperture of a diaphragm 4 and is subsequently split by a dichroic mirror 6 which transmits a first beam part to a photo-cell 10 connected via a servomotor to appropriately move a neutral wedge filter 9 in response to the light intensity falling thereupon and which reflects a second beam part to be focused on a selected aperture of a diaphragm 7, the image thereof being reproduced for movement in two coordinate directions upon a photographic layer S by passage of the second beam part through first and second telecentric ray producing systems and a diaphragm 18 wherein the first system comprises objectives 11, 16, mirrors 13, 13a, 15, 17 and a rotatable mirror 14 of a mirror galvanometer which deflect the second beam part in one co-ordinate direction within the aperture of diaphragm 18 and the second system comprises objectives 20, 25, mirrors 19, 22, 23, 23a, and a rotatable mirror 24 of a second mirror galvanometer which deflects the second beam part in the other mutually perpendicular co-ordinate direction. Termination and commencement of line drawing is determined by a shutter 8 whilst line thickness is dependent upon the aperture in the diaphragm 7, a displaceable condenser 5 ensuring that only the aperture chosen is fully illuminated. The diaphragm 7 may be provided with a plurality of different sized apertures and mounted for rotation, so that an aperture may be selectively aligned with the incident beam or the diaphragm 7 may be non-rotatable, but replaceable by another having a different sized aperture.

The pack is moved towards the furnace by means of a frame 7, having retainers 8 against which the last plate of the pack rests, the frame being driven by a threaded rod 6 acting on a nut 9 associated with the frame 7. The pack is replenished by making use of a replenishing rack 11 which includes a stand 21 connected to a nut 23 engaging the rod 6. In use the stand is operated manually to bring forward a fresh pack into contact with the preceding pack, the frame 7 disengaged and moved backward to grip the replenished pack and finally the stand 21 is disengaged so that there is no interruption in the forward movement of the pack. The furnace 2 includes a plurality of infra-red heat sources 3 emitting short-wave radiation..
