IPC: G01N21/31
Filed: 1958-11-04
Abstract: 902,732. Infra-red fluid analysis. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 3, 1959 [Nov. 4, 1958; Feb. 17, 1959; May 14, 1959], Nos. 35304/58, 5525/59 and 16570/59. Class 40 (3). In infra-red gas analysis apparatus differing wavebands of light pass through an absorbtion tube sequentially and repeatedly to a detector, the output of which is an absorption signal at one frequency and a standardizing signal at a second frequency, means being provided to compare said signals. In the light beam between a source 1 (Fig. 1 of the second Provisional Specification), and an absorption tube 6 are a chopper 3 interrupting the light beam at 1000 c/s. and a narrow band filter 5 rocked to and fro at 2 c/s. The output of the photo-cell 7 is therefore a 1000 c/s carrier signal modulated at 2 c/s by the filter 5. On demodulation a D.C. voltage proportional to the carrier signal controls the photo-cell voltage to eliminate spurious intensity variations. Filter 5 may be replaced by two band-pass filters transversely oscillated alternately into and out of the light beam. In a second embodiment the filter and chopper are replaced by a compound filter (Fig. 2 of the first Provisional Specification). Sections S transmit a wavelength which is absorbed by the test gas and sections R and T transmit wavelengths not absorbed. Thus absorption and standardizing signals, at different frequencies, emanate from the photo-cell. The standardizing signal is fed to the slide wire of a self-balancing potentiometer to the signal input of which is applied the absorption signal, or alternatively controls the gain of an absorption signal amplifier.

Title: Improvements in or relating to manipulating tools
Inventor: GERARD BERNARD
IPC: B25J13/00
Filed: 1962-09-18
Abstract: 1,001,652. Fuelling reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Sept. 18, 1962 [Sept. 18, 1961], No. 35478/62. Heading G6C. [Also in Division B8] A gripping device with jaws 43, Fig. 5, is supported on a pinion 23, Fig. 1, which is suspended by a chain 22, from a differential winch, which, by lowering the gripping device on to an object (e.g. a fuel element) to be lifted, causes the jaws to close, and by rotating the pinion moves sash bolts 25 to lock the jaws either open or closed. When the jaws are lowered on to a fuel element, a cam member 42, Fig. 5, attached to rods 50, 40, is pushed upwards against a spring 41 by a handle 48 on the element to close the jaws 43, Fig. 6. Upward movement of the rods 50, 40 also raises a member 45 so that a slot 47 therein is lifted clear of the end 25a of the sash bolt 25. Whilst the rods 50, 40 are raised the pinion 23 is rotated through 180 degrees by turning a wheel 17, Fig. 1, to allow a bolt 18 to be moved from a hole 20 to a hole 21. The movement of the wheel 17 causes pinions 13, 14 to which are attached chain pinions 15, 16, to rotate in opposite directions thereby rotating the pinion 23 to bring the end 25b of the sash bolt 25 to a position where it prevents the member 45, Fig. 6, and therefore the rods 50, 40 and cam member 42 from descending. The jaws 43 are thus locked in a closed position. The winch is now driven either by a motor 3, Fig. 1, or a handwheel 4 to raise the load. A selector lever 9 moves clutches so that either of the driving means may be selected. A counter on the transmission system indicates the position of the lifting device by measuring the length of chain paid out. The ends of chain 22 pass over pinions 32, Fig, 4, 33 (not shown), which rotate on a shaft 34. This shaft 34 is attached to spring tensioning means 37 by a sliding shaft 36. In a second embodiment the manual winch drive may be replaced by a differential coupling wherein a first planetary device is activated by the motor, while the satellite-carrying crown may be moved by the manual wheel. The second planetary device is secured to the winch shaft and when operating the fixed point of the differential coupling is constituted by one or other of the two controls not being used.

A capacitor for a fluorescent lamp ballast circuit comprises an assembly of electrodes and interposed dielectrics with a thermal fuse operative to disconnect the capacitor at a predetermined temperature; the fuse comprising fusible conductive material within the capacitor assembly provided in the region thereof with electrical stress reducing means to reduce migration of the fusible material. The capacitor is wound, e.g. of aluminium foil and kraft paper dielectric with emergent connecting tabs, enclosed in a steel can, and impregnated with e.g. chlorinated diphenyl or mineral oil; the can being potted in asphalt in a container with other components of the ballast circuit (Figs. 1, 2, 3, 4, not shown). At the inner end of the winding a separated section 19c of electrode foil is connected to a main length 19d of electrode foil by a fusible metal member 23a to which a connecting tab 24a is attached. A further electrode foil 20a with connecting tab 26, and dielectric sheets 21a, 22a are wound together in conventional manner; the member 23a being covered by a further coextensive dielectric strip 25 of kraft paper, polyethylene, cellulose acetate or the like to reduce the dielectric stress so as to retard the rate of migration of the fusible metal, with consequent over-heating and breakdown. A further dielectric sheet 25b may be interposed between the reverse exposed surface of 23a and dielectric 21a (Figs. 4a, 4b). The remaining foil 20a may be split into two electrodes each with its connecting tab. In a modification (Fig. 5, not shown) a portion of the further electrode foil may be removed leaving an isolated portion separated from the operative portion by a gap equivalent to the fusible member with a further offset. In a further modification (Fig. 6, not shown) spaced components of one electrode foil have a gap opposed to that between components of the other electrode which is bridged by a fusible member covered by a further dielectric sheet; the electrode foils being conventionally wound with interposed dielectrics. A component of the one electrode foil may be isolated or have a connecting tab to provide a two-unit capacitor with a common fused electrode.

Abstract: 869,156. Electric selective signalling systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 4, 1959 [Nov. 5, 1958], No. 35556/58. Class 40 (1). An analogue-to-digital converter comprises a column of electrically conducting liquid which is displaced longitudinally in accordance with an analogue quantity to be measured, an electrical conductor which is reciprocated cyclically so as to contact the liquid and energize a control circuit for a part of each cycle dependent upon the displacement of the liquid, and an impulse generator whose output is controlled by the control circuit to produce successive trains of impulses, the number in each train being numerically representative of the displacement of liquid and hence the analogue quantity. A motor 5 drives a Scott mechanism 4 to sinusoidally oscillate a contact 3, and synchronously rotates a disc 6 having sinusoidally separated holes through which light shines on to a photo-cell 7 to supply pulses to a gate 9. Upon immersion of the contact 3 in the mercury of a manometer 2 a circuit is " made " to the gate 9 and allows pulses from the photo-cell to pass to a counter 11 for the duration of the immersion. The pulse count is an indication of the height of the mercury which may be regarded as an analogue input. In the embodiment the manometer indicates changes of pressure supplied by a Pitot tube in a wind tunnel. The disc 6 may be arranged to produce pulses representing different functions of pressure by different spacings of the holes.

Title: Improvements in or relating to turn-up or turn-over gear for use with rolling mills and the like
Inventor: SHIMELD TOM ALEXANDER GEORGE
IPC: B21B39/20
Filed: 1956-11-23
Abstract: 821,288. Rolling. DAVY & UNITED ENGINEERING CO. Ltd. Nov. 22, 1957 [Nov. 23, 1956], No. 35956/56. Class 83 (4). A turn-up gear for rolled steel sections being fed along skid rails comprises a turning member having at least two limbs set at an angle, means to raise and lower the member and guide-rails so arranged that as the member is raised a section on the skid rails is caught at the junction of said limbs, lifted, turned through substantially 90 degrees and as the member is lowered is deposited on the skid rails in its turned position. The turning- member 13 is L-shaped with its longer limb 23 coupled to a rotatable shaft 3 driven by a reversible motor through rods 15 and bifurcated arms 14 keyed to the shaft and through a bar 7 and arm 4 rotatable on the shaft. A metal pad 10 and an intervening plate 9 define the lower limit of the stroke of the bar 7. Parallel movement of the bar 7 is ensured by an arm 20 coupled to the bar at 21 and to the machine frame at 19. At the junction of its links 23, 24, the member 13 carries rollers 26 adapted to be run in guiderails 27, 28, 29, 30. In operation, as the shaft 3 turns and raises the rods 15 the member is lifted from the position shown in Fig. 2 with the rollers 26 running up guide-rails 30 until they contact rails 27 when the arm 23 is horizontal with section 2 resting on skid rails 1 just above it. During this movement the vertical bar 7 counterbalances the member and remains stationary. Upon further rotation of the shaft 3, as the rollers 26 move along the rails 27, the member 13 catches section 2, while the end of the member connected to the bar 7 is lifted arcwise thereby raising the bar to the peak position shown in Fig. 4 when the rollers reach the end of their run along the rails 27. The motor is then reversed and the member lowered substantially in the same angular position as the rollers 26 descend past guide rails 28 until the shorter arm 24 of the member is below the level of the skid rails 1 and the section 2 is deposited on them in its turned position. As the rod 15 is further lowered the rollers 26 engage guide rails 29 which conduct the member to its Fig. 2 position. Specification 799,941 is referred to.
