Abstract: 1,227,435. Temperature responsive actuating elements. INDUSTRIAL NUCLEONICS CORP. April 26, 1968 [April 27, 1967 (3)], No.19991/68. Heading G1D. [Also in Division H5] In a gauge utilizing nuclear radiation e.g. a thickness gauge, the container for the radio-active source comprises a shutter adapted to expose or shield the source as desired, and the shutter operating mechanism is fitted with means responsive to ambient temperatures above a predetermined ambient temperature to close the shutter and automatically lock it when closed. Preferably the shutter operating mechanism is energized to open the shutter, and the temperature responsive means de-energizes the mechanism when subjected to a temperature in excess of said predetermined temperature. It is preferred that the locking means is responsive to temperatures in excess of a further predetermined temperature greater than the first predetermined temperature to lock the shutter in the closed position. The shutter member may have parallel sides which engage in appropriately positioned guides. The shutter operating mechanism may be an electric or hydraulic motor and the temperature sensitive device may be a fuse or plastic tube which ruptures to break the electric or hydraulic circuit, the shutter being closed by the action of return springs. The locking device responsive to a slightly higher temperature may comprise an explosive charge 100 Fig. 6, adapted to drive a hardened steel pin 95 into at least one of the guides 39, to distort it and thus lock the shutter 40 in position. In Fig.9 (not shown), the pin is dispensed with and just the explosive force of charge 100 is utilized to distort the guides. In an alternative embodiment, the locking means comprises a locking member restrained from moving into a locking engagement with the shutter by a thermally responsive barrier e.g. a eutectic alloy. In Fig. 13 a spring-loaded bolt 191 is restrained from engagement in recess 109 by shoulders 195 of a eutectic alloy. Melting of the alloy permits the bolt to engage and lock the shutter. The bore 185 may be fitted with a weephole Fig. 15 (not shown) to permit the molten alloy to escape. In an alternative embodiment Fig. 18, a spring 295, with arms 297, 298 is positioned in a V-shaped recess in shutters 40, the arms being restrained from engagement with recesses 107, 108 by a barrier of eutectic alloy. Exposure to a temperature in excess of the predetermined temperature melts the alloy, permits the ends of the spring to engage the recesses and locks the shutter.

Abstract: 1,233,318. Photo-electric position determination. ERNST LEITZ G.m.b.H. July 8, 1969 [Aug.1, 1968], No.34421/69. Heading G1A. [Also in Divisions G2, G3, H3 and H5] Specification describes a method of producing an oscillating beam, of light 14 and the use of said beam of light in determining the position of various reflecting objects. Said method comprises directing a beam of light from a source 1 (which may include optical fibres) through a stationery diaphragm 4 (and possibly a filter 3) on to a deflecting means 5. Said means may comprise a right angled doubly reflecting prism as shown, or a penta-prism or a pair of mirrors. The deflecting means or prism is subjected to a linear oscillatory motion in a plane perpendicular to the incident beam, by means of a resiliently mounted shaft 7 carrying the prism 5 and moved in an oscillatory motion by the action of A.C. current fed armatures 9 moving in the fields of magnets 8. The beam deflected by means 5, oscillates laterally with twice the amplitude of the prism movement and is further deflected by fixed prism 13 to form the final oscillatory beam 14. To determine the position of a measurement mark system 24, comprising contrasting lines on background, beam 14 is oscillated across the system and the pulsed reflected light is passed by beam splitter 20 and 27 to a multiplier 28. The reflected light also passes to sighting means 31. To produce a two dimensional e.g. raster scan, of the beam, the second prism (6) can be turned through 90 degress, Fig. 2 (not shown) and caused to linearly oscillates in the direction 90 degress to the direction of oscillation of prism (5). The frequencies of the two oscillations should be substantially different to aid discriminators of respective componant in the detector output. The diaphragm aperture may now take on the shape of a cross (44). No details are given of the receiver in which the position of the system 24 is determined.

[Also in Division G1] In an apparatus for analysis of a sample by flame spectrometry, the sample, contained in a funnel-shaped container 10, is atomized by pressurized air at the nozzle 52, and is burnt as a mixture with fuel gas at the burner head 16. Fuel gas is supplied from a mains supply 25 via a pressure regulator 26 (Fig. 1) to the inlet nipple 45. Compressed air is fed in to the burner through nipple 41, a portion of the air flowing to the atomizing nozzle, the remainder mixing with the fuel gas in the Venturi passage 39 (Fig. 2). In a different embodiment (Fig. 1) the gas and air may be mixed in a Venturi 30, external of the burner body. The mixture of fuel, air, and atomized sample flows up the burner barrel 14 to an inner grid 67 which smooths the flow of the mixture to the upper grid 68 where the mixture burns. A chimney 69 surrounds the flame, a supply of air being introduced through conduit 72 to prevent the deposit of residues on the chimney. The barrel 14 contains a baffle 60 and a tubular screen 57, which together deflect droplets of unatomized sample to the drain outlet 62. The detection system includes a lens 75, Fig. 1, a filter 76, and a second lens 77, the light from a selected part of the flame passing through these to a photo-cell 78, which may be an ironselenium cell or a silicon photo diode. The electrical energy from the photo-cell controls an electrical detector such as a galvanometer 80.

A tubular element 14 e.g. a pneumatic spring bellows, or a flexible pipe coupling, comprises two or more layers of rubberized fabric, which may be located between inner and outer unreinforced rubber layers, and has conically flared ends incorporating reinforcing rings 12. In forming the element 14, an inner unreinforced rubber layer, which may comprise an extruded flexible tube, is applied to a rotary drum 1 in a cylindrical region thereof displaced from a member 3, which is screwed or welded to the end adjacent the drum rotating mechanism (not shown). Two or more layers of rubberized fabric are then wound on to the drum 1 during rotation thereof, followed optionally by an outer coating of rubber, to produce a cylindrical configuration which is then drawn off the drum 1, from the end opposite to the driven end. After flaring of the ends of the element 4 to the desired conical configuration, the element 14 is re-mounted on the drum 1, and the reinforcing rings 12 slipped thereon with the flared ends of the element in abutment with the member 3 and with a similarly configured member 13 which is mounted to a locking device, Fig. 2 (not shown), for attachment to the drum 1. After locating each ring 12 on the element 14 adjacent a shoulder 3a or 13a of the members 3 or 13, the rings 12 are incorporated by progressively folding over the ends of the element 14 during rotation of the drum 1, the element being subsequently shaped and/or vulcanized in a divided mould.
