Title: Improvements in or relating to apparatus for the manufacture of piezo-electric crystal oscillator or filter plates
Inventor: FULLER DENNIS QUINTRELL
IPC: H03H3/02
Filed: 1954-02-26
Abstract: 808,804. Piezo-electric crystals. PYE Ltd. May 16, 1955 [Feb. 26, 1954], No. 4825/54. Class 40 (8). Deposition of electrodes on a piezo electric plate of e.g. quartz is automatically terminated when the desired resonant frequency is attained. The plates 2 are mounted with their terminals 2a, 2b on a turret 1 which is rotated intermittently by a motor 4 in such a manner that as each plate comes in turn opposite the deposiing station the terminals 2a, 2b are connected by spring contact blades 7 to a test oscillator 8. The electrode material is carried on a moving wire or strip 14 which is heated either directly or by a filament 13. The amount of electrode material on the carrier 14 is such that all of it is evaporated, so that the amount per unit time which passes through the mask 11 on to the plate 2 is determined by the speed of the carrier 14. When the difference between the frequency of the test oscillator 8 and that of a standard oscillator 10 becomes zero, an electronic switch in the comparator 12 actuates the relays 18, 19 to terminate deposition and to actuate the turret in such a manner that another crystal plate is brought opposite the mask 11. The speed of the wire 14 may be controlled electronically in such a manner that the rate of deposition decreases as the plate approaches the correct frequency.

[Class 7 (iii).] In a carburetter in which fuel is fed through a hollow rotary shaft and atomized by centrifugal ejection through ducts in a disc mounted on the shaft, the shaft being rotated by a fan axially displaceable by air pressure for controlling a fuel supply valve, the shaft is slidably held in a bearing and is supported at one end on a cushion which normally maintains the fuel supply valve, supported by the shaft, in the closed position, the shaft being displaced by the air current in opposition to the cushion for opening the valve. Air entering by a controlled port 1 passes between the coils of a spring 4, disposed between a member 2 on a cover 6 and an observation glass 5, to fixed vanes 7 adapted to give it a whirling motion which throws out impurities towards the observation glass and directs the air on to the blades of a fan 8 mounted between discs on the end of a hollow shaft 9. The shaft 9 is rotatable in the cover 6 and is adapted to supply fuel to ducts in the fan when engine suction draws the fan and shaft downwards and allows a ball valve 10 at the top of the shaft to open, an adjustable resilient support 12 secured in the body of the carburetter opposing the downward motion. A conical screen 14 secured by a spring 15 assists in mixing the fuel and air. In a modification, the air port is uncontrolled and concentric valve rings, coaxial with the shaft, control the passage of combustible mixture.

A valve 20, Fig. 2, allows engine exhaust gases to be by-passed, directly between inlet and outlet pipes 14, 16 of an after-burner device comprising an annular Venturi 45 having air-inlet ports 49 and leading via ports 37 to a burner chamber 34, in such amounts that the air admixture varies inversely as the total exhaust gas flow. The pipe 16 leads to a silencer. The valve 20 is opened by exhaust gas pressure against the loading of a spring or a weight W, and through a linkage 24, 26, eccentric 28 and a fin 30 slides the chamber 34 to vary the Venturi throat crosssection. A set screw 33 defines an adjustable minimum throat cross-section. A spark plug 50 initiates ignition, and the air ports 49 are supplied from an intake 47. A glass fibre or asbestos coating 52 is protected by a metal foil and wire mesh layer 53. The chamber 34 may have an expanded-metal screen across it. The burner device is in two stamped sections axially flanged together. The valve 20 may direct some of the by-passed gases to a cooler feeding the engine intake manifold. In a modification the burner chamber is slid solely by a member responsive to exhaust gas temperature. Fig. 6 shows a burner chamber 34, and a valve 59 replacing the valve 20, both operated by floating levers 63 pivoted also to rods 61 retaining under spring loading a flange 61<SP>1</SP> attached to the main device which is connected to an exhaust manifold 2<SP>1</SP> by an expansible bellows 56<SP>1</SP>. A tube 51<SP>1</SP> allows crankcase vapours to be drawn in with the air. In a combined afterburner and silencer, Fig. 9, which may have an elliptical or rectangular crosssection, two rectangular crosssection Venturis 80, 80<SP>1</SP> are used with the inlet end of the silencer casing 70, air being fed to three ports or rows of ports 85 and crankcase vapours which have passed a flame arrester (not shown) to one port or port row 85. In Fig. 11 (not shown) this arrangement is modified in that the direction of flow through the Venturis is the same as that through the silencer generally, and a second spark plug is provided at the entry to the silencing section proper. Many other possible minor variations are specified.
