Abstract: 873,904. Photo-electric vibration testing. FAIREY AIR SURVEYS Ltd. March 4, 1959 [Feb. 20, 1958], No. 5613/58. Class 40(3) [Also in Groups XIX and XXXII] Apparatus for the dynamic testing of resilient units, e.g. for analyzing the properties of antivibration mountings comprises an input member, which may consist of a table 13 carried by a frame 10, and an output member 20 between which the unit under test (not shown) is secured, and constraining means 27 to constrain the movement between the members 13, 20 to relative linear movement along a fixed path which can be adjusted to allow the unit to be subjected to linear vibrations in a number of directions by adjusting the constraining means 27 relative to the members 13, 20 about an axis perpendicular to the path of the relative movement. The output member comprises a loading beam 20 which extends symmetrically across the resilient unit and carries at each end a bar 21 on which weights may be clamped. The constraining means comprises four parallel blade springs 27 each rigidly clamped at its ends to blocks 25, 26 which are connected to the frame 10 and the beam 20 respectively by bearings which permit rotation of the blocks 25, 26 about an axis parallel to the length of the undeflected blades 27. These bearings may be clamped by thumb screws 30, 31. The test rig is mounted on a vibrating table secured to a rigid structure and vibrated by an electro-magnetic vibrator, the frequency and amplitude of vibration being controlled -by a V.L.F. oscillator and amplifier. The input and output displacements are converted to electrical signals by a photo-electric pick-up tube 40 clamped to a fixed support and extending through openings 37, 38 in the frame 10, the blocks 25, 26 and beam 20. These signals are displayed on a double-beam oscillograph against a suitable time base. The tube 40, Fig. 4, comprises a lamp 45 supplied with D.C., photo-electric cells 46, 47 and partition masks 50, 51 each having a slit formed in it inclined at 45 degrees to the horizontal. Diffusers 48, 49 ensure that the illumination is approximately uniform over the area of the slits. Cut-off slides 52, 53 attached to the beam 20 and the frame 10 respectively to vibrate at their respective amplitudes obturate more or less of the slits to vary the amount of illumination reaching the cells 46,47. The oscillograph may be mounted on a separate control console housing the oscillator and the amplifier may be located in the base of the vibrating table.

Abstract: 608,789. Cathode-ray tubes. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Feb. 28, 1946, No. 6286. Drawings to Specification. [Class 39 (i)] In a dark trace cathode-ray tube, the screen employed for producing the dark image comprises a film of solid material consisting of two layers, one of potassium chloride or lithium iodide, and the other of rubidium chloride or potassium bromide. Both the colour and the persistence of traces formed on the second or top layer contrast with the lower layer. The second layer is thinner than the foundation layer to permit of penetration of the electron beam. The top layers, rubidium chloride or potassium bromide, are characterised by rapid decay, which may be made more rapid still, by associating the short persistence halide with a minor amount of one of the metal halides mentioned in Specification 608,546. The two layers are deposited by vaporization in two separate operations. When the lithium iodide is first vaporized, the resulting film which would otherwise tend to be transparent, is preferably whitened by a few minutes exposure to water vapour at a pressure of about 4.5 to 7.0 minutes Hg, corresponding to the exposure pressure of water at a temperature within the range of about 0‹ to 6‹ C., followed by a bakeout before the top layer is deposited.

[Class 123(i)] The level I of a volatile liquid, e.g. liquid oxygen, in a vaporizer A is determined by measuring the pressure difference between the gas above the liquid, and gas bubbling through a portion of the liquid being supplied to the vaporizer and prior to the introduction of this liquid into the vaporizer. Liquid is supplied through a pipe N and enters the vaporizer A at the point D. Part, however, is led off through a pipe E in which it vaporizes and the pressure of the gas so formed is measured by the gauge H, the other limb of which is connected by a pipe F with the gas above the liquid. In a modification, Figs. 3 and 4, (not shown), all or part respectively of the liquid is led into an auxiliary vessel communicating at its lower end with the vaporizer A, the pipes E, F being then connected to the bottom and top respectively of the auxiliary vessel. In a further modification, the auxiliary vessel is in two parts connected by two tubes. Specification 619,949 is referred to.
