Title: The coating of metal bodies with zirconium
Inventor: ROWLANDS VERNON
IPC: C23C4/08
Filed: 1960-12-06
Abstract: A surface of an anode or a cathode shield for a thermionic valve, or a metal part for a mercury arc rectifier, is coated with zirconium by feeding a wire, rod or strip of zirconium metal into a flame, e.g. formed by burning acetylene or hydrogen with oxygen, to melt the metal, and directing on to the molten metal a gas blast, e.g. of air, argon or nitrogen to atomize and spray it on to the surface.  The resulting coating is of overlapping zirconium metal droplets and may contain some ZrO2. Prior to coating, the surface is preferably roughened by grit blasting. For example, a nickel tube is grit blasted with alumina grit prior to rotating the tube on a mandrel and spraying it in one or several stages.  For copper bodies, an initial coating of nickel may be applied prior to the zirconium coating. Prior art discloses metal parts by painting thereon a liquid suspension of pure 200/300 mesh zirconium powder in a binder and sintering in a vacuum.

Title: Photographic camera or shutter operating mechanism therefor
IPC: G03B7/16
Filed: 1969-08-22
Abstract: 1,246,868. Camera exposure control. HATTORI TOKEITEN K. K. Aug. 22, 1969 [Aug. 23, 1968], No.42084/69. Heading G2A. If subject brightness is below a predetermined value, the shutter release couples with a member which charges the camera to flash operation; if brightness is above this value the coupling is not effected. As shown, on depressing release 1, a pin 5 thereon allows a switch 21 to close. If the brightness as measured by a photo-resistor 26 is low the pointer 29 of an ammeter 28 will remain in contact with a circuit point 27 and an electromagnet 20 will be energized. This holds a lever 19, and thus a lever 16, which would otherwise move when released by movement of a pin 6 on release 1. Upon further depression, release 1 abuts lever 16 lowering it and thus lowering a plate 7 so that a pin 11 thereon allows a switch 22 to close, which actuates a flash-light exposure control device (not shown), operating according to various set values. The shutter now releases, and a synchro-switch 23 closes energizing a flash device 25. If the brightness is high, the contact 27, 29 is broken, electromagnet 20 is not energized, and levers 16, 19 are rotated by springs 15, 18. Thus lever 16 is moved out of alignment with release 1 and is not depressed thereby so that switch 22 remains open and flash device 25 is not operated. A trigger circuit (R 1 , R 2 , R 3 , 26) Fig. 4 (not shown), which determines whether or not a transistor (30) conducts, may control the energizing of electromagnet 20 instead of ammeter and pointer 28, 29.

Filed: 1972-09-12
Abstract: 1403259 Fluid-pressure servomotor systems BOWLES FLUIDICS CORP 12 Sept 1972 [17 Sept 1971] 42380/72 Heading G3P [Also in Division F1] A fuel injection system is controlled by the pressure of air in a receiver 15 situated in the engine manifold 10 to receive air from a jet 13 to which the pressure of the supply is varied in accordance with at least one variable. In the preferred embodiment, the manifold pressure Pm is fed through restrictors A5, A9, Fig. 5, preventing sonic flow to a fluidic amplifier 18 having an output P4 which varies non-linearly with Pm and corresponds to fuel/air ratio. P4 is modified in accordance with engine temperature by a bleedoff valve A3 connected to a bi-metallic element 19 and in combination with manifold pressure P1 sensed by a bellows 23 and a pressure corresponding to manifold temperature sensed by a second bi-metallic element 21 determines the pressure of the supply through fixed and variable restrictors A6 and A7 to the nozzle 13. The pressure in the receiver 15 is a function of the nozzle pressure and the flow in the manifold and is amplified by cascaded amplifiers 25 ... 27 to provide an output P5 which is fed into a turther series of amplifiers 31 connected to capacitors V1, V2 and through diodes D1 ... D4 to inputs P8, P9 which receive timing pulses generated by a drum 32 rotating at half the speed of the engine. The output P7 from the amplifiers is thus made to correspond to fuel delivery per stroke and operates an injection pump 45 through a further series of amplifiers (41), Fig. 7 (not shown) and a bellows coupled to lever 46, a valve (48) and resistors (24, R5) providing feed-back. The pulse in input P9 is fed through a diode (D5), Fig. 8 (not shown), and a capacitor (V3) to an OR/NOR gate (52) which switches to provide an output pulse when engine speed falls, the pulse being amplified to provide a pressure differential ql, q2 which forms a vortex in the manifold to  throttle air-flow. The system pressure P+ is supplied by a pump and regulator 2.

Abstract: 1404106 Heating combustion air, thermostatic exhaust cut-out valves AUDI NSU AUTO UNION AG 10 Sept 1973 [19 Sept 1972] 42452/73 Heading F1B [Also in Division F2] An I.C. engine, of a vehicle, has means for controlling a process in accordance with warming up of the engine, comprising a control device having two mutually relatively movable components, each of which is connected to a respective one of two coaxial relatively axially movable pipes through which the engine exhaust gases pass, so that the thermal expansion of one or both pipes due to the heat of the exhaust gases causes relative movement of the components. A thermal exhaust gas reactor 1 consists of an outer tube 4 and an inner tube 3 both fixed to a flange 2 and separated by a heat-insulating layer 4a. The free end of the inner tube is guided in a funnel shaped member 6 secured to the outer tube, has slots 7 and carries a hollow perforated cone 8. When the device is cold, exhaust gas passes through the perforations and quickly heats the cone to a temperature sufficient to maintain after-combustion. Meanwhile the inner tube expands in length so that the slots move clear of the smaller diameter portion of the member 6 and exhaust gas is then able to flow freely to the exhaust pipe 10 without excessive back pressure. In a first modification the cone is replaced by a blanking-off plate and the exhaust gas flows through an opening in the tube wall, upstream of its free end, to a catalytic reactor. As the inner tube expands, the opening is closed and the slots are opened. In a second modification, Fig. 5, for heating combustion air, there is an inlet 17 and an outlet 18 to a annular space 16 which is heated by exhaust gas passing through the inner tube. A slide valve member 20 attached to the tube 3' moves to close the outlet 18 as the tube 3' expands on heating.

In an arrangement for reading a circular scale 1 of an angle measuring instrument in which the image of a portion 2 of the scale 1 is projected by lenses 6, 7 and prisms 4, 5 on to the diametrically opposed portion 3 of the scale and an image of both portions is projected by a system 9, 10 into a plane 11 where an index mark gives the coarse reading, the vernier reading being obtained by rotation of a double thickness plane plate 8b, 8a which shifts the image of one major scale division in portion 2 into coincidence with a corresponding division in portion 3, an error may be made in the coarse reading. Accordingly a plane parallel plate 8b is extended to provide a single thickness plane plate to shift the composite image projected into plane 11 so that the major division is aligned with the coarse index. The latter may then take the form of an opaque strip with a gap which shows a digit corresponding to the coarse reading.
