Title: Spark discharge monitoring device
IPC: G01L23/22
Filed: 1959-11-20
Abstract: 903,241. Testing ignition systems. NORTH AMERICAN AVIATION Inc. Nov. 20, 1959 [Nov. 25, 1958], No. 39404/59. Class 37. [Also in Groups XXVI and XXVII] A sparking-plug is provided with a monitoring electrode which draws a non-sparking ionization current. Fig. 1 shows an igniter 2 in the combustion chamber 1 of a rocket motor. When a high-voltage pulse is fed from the ignition exciter 4 to electrode 3 a spark breakdown occurs across the surface of the semi-conducting layer 8 to the earthed electrode 6. The spark causes an ionization current to flow between the high voltage electrode 3 and a monitoring electrode 9, the current being amplified at 17 and fed to an instrument 19 which provides an indication proportional to the spark energy. If the spark is satisfactory, relay 5 becomes energized, disconnecting indicator lamp 26, lighting indicator lamp 25 and energizing solenoid valves 21, 22, admitting supply of fuel and oxidizer to the combustion chamber 1. Fig. 3 shows a section through a sparking-plug in which the high-voltage electrode 39 and the monitoring electrode 44 are separated from the earthed outer casing 38 by insulation 40. The high-voltage electrode 39 projects beyond the surface of a semi-conducting oxide layer 42.

Title: Improvements in or relating to Apparatus and Method of Metal Extrusion
Inventor: MCALLAN JOHN DEWAR
IPC: B21C23/00
Filed: 1965-09-17
Abstract: 1,155,599. Extruding. NATIONAL RESEARCH DEVELOPMENT CORP. 16 Sept., 1966 [17 Sept., 1965], No. 39796/65. Heading B3P. A metal billet 12 of unrestricted length is extruded by feeding it into a tubular ram 10, applying radial pressure to the ram which causes it to grip the billet, advancing the ram to extrude the billet through a die 15, releasing the radial pressure and retracting the ram. The latter is actuated by a double-acting piston 11 to which pressure fluid is supplied through ports 34, 36. For contracting the ram radially, pressure fluid such as oil is admitted into chamber 14 through duct 19. Forwardly of the ram, an extrusion chamber 16 is supplied with pressure fluid from an intensifier through duct 20; this pressure may be sufficient only to prevent upsetting of the billet between the ram 10 and die 15 or it may cause hydrostatic extrusion through the die. A seal (8), Fig. 3 (not shown), may be provided at the forward end of the hollow ram. After release of the pressure in chamber 14, the ram and piston 10, 11 are retracted whilst the billet is held stationary by a collet chuck 38 actuated by a fluid pressure cylinder 40. The extruded product 25 may pass into a second hydrostatic extrusion chamber (21), Fig. 3 (not shown), from which it is further extruded through a die (31). A sleeve (24), Fig. 4 (not shown), at the exit of the first die 31 may be contracted on to the extruded product by pressure in chamber (21) to prevent backward movement through the die 31. A rotatable reel (27) at the outlet of die 15, Fig. 5 (not shown), causes the product 25 to be coiled within the second extrusion chamber (21), thereby permitting continuous extrusion therefrom. In a further embodiment, Fig. 6, the ram 56 is contracted by fluid pressure in chamber 65 produced by a second ram 57 connected to a low pressure actuated piston 55. The ram 56 is moved axially by piston 54 biased by spring washers 73. After extrusion through die 61, the product is further extruded through a die 60 by hydrostatic pressure produced by inward movement of the die by piston 58. The first die 61 is movable from a seating to permit one-way flow of fluid from the right to left into the main extrusion chamber 67. During extrusion a space 64 between the two pistons 54, 55 is pressurized to cause simultaneous movement of both pistons. A plurality of dies and hydrostatic chambers may be arranged in tandem. The initial billet 12 may be fed directly, whilst still hot, from a continuous casting plant. The extrusion process may be controlled automatically by a timer which energizes electricallyactuated valves.

Title: Improvements in or relating to the manufacture of transparency mounts
IPC: G03B35/24
Filed: 1959-11-24
Abstract: 873,143. Coating webs. KODAK Ltd. Nov. 24, 1959 [Nov. 24, 1958], No. 39820/59. Class 140. [Also in Group XL (b)] A device for detecting and indicating inadequate or faulty adhesive stripes applied to the tacking areas of a moving web of transparency mounts in which the adhesive stripes and the position of the web in alignment therewith form a scanning zone which reflects light varying in intensity in dependence on the amount of adhesive carried by the zone, comprises means for directing a beam of light on to the scanning zone of the web from which light is reflected on to a light-sensitive cell which in response to the variation in light intensity causes the actuation of means for deforming an edge of the web whenever the light beam strikes a portion of the scanning zone having insufficient adhesive. The web 1 comprises apertures 2 for the transparency mounts formed in two groups each having associated adhesive stripes 3 applied by apparatus as described in Specification 837,183. The detecting device for each of the two sections of the web comprises a photo-sensitive cell 11 receiving a light beam from the source 6 reflected by the stripes 3 whilst a second photocell 14 receives a beam from a source 12 and an apertured mask 13 in conjunction with that passage of aperture 2 in such a way that the ribs 15 between apertures 2 are scanned simultaneously with the exposure of the stripe 3 to the beam from the source 6. If during the blockage by rib portion 15 of light through an aperture 2 to the cell 14 a faulty stripe 3 is detected, a solenoid 5 is energized so that its armature 16 operates a punch 17 to effect in conjunction with an anvil 18, a crimping of the edge of the web at a position opposite the defective portion of the stripe 3.  Circuit arrangement, Fig. 6.-During the passage of the apertured web portion 2 in front of the cell 14, the valve 15 is conductive and the decreased potential from its anode prevents the valve 24 or 24<SP>1</SP> from conducting, irrespective of the actuation of the cell 11 or 11<SP>1</SP>. During the passage of the rib or web portion 15 in front of the cell 14, the conduction of the valve 51 is much reduced, and the increased potential from its anode permits the valve 24 or 24<SP>1</SP> to conduct if the photo-cell 11 or 11<SP>1</SP> detects a faulty adhesive stripe 3. The conductive operation of a valve, for example 24, operates a relay 2 opening a normally closed contact 28 releasing a relay 29 which moves contact-member 30 from position B to position A. The relay 29 also moves contact-member 33 from position D to position C to operate the solenoid 5 and punch to effect the crimping operation. When the defective portion of the stripe 3 has passed, the conduction of the valve 24 ceases and relay 27 releases so that contact 28 is closed, but relay 29 remains de-energized until the parallel-connected capacitor 31 has been charged to provide operation by solenoid 5 for a time sufficient to effect the crimping operation.
