Abstract: 234,345. Osterhout, G. H. Sept. 22, 1924. Reservoir pens.-In a reservoir pen of the type provided with a screw-actuated self-filling plunger, the plunger is reciprocated in the barrel by means of a hollow spiral, the passage through which enables air to pass from behind the plunger to a vent in the point-section. The barrel 10, which is preferably elliptical in shape and may be made of transparent material, is provided at its closed rear end with a rotatable head 25 connected to the spiral 19, leakage of ink being prevented by washers surrounding the shank 31. The central passage in the spiral communicates with the interior of the barrel behind the plunger 21 through an opening 20 near the rear end. The front end of the spiral is journaled in an aperture 35 in the feed plug 16, the aperture being deeper than the length of the trunnion 34 on the spiral so as to form an air chamber which communicates with the atmosphere through lateral openings. Leakage of ink into this chamber is prevented by washers. Air trapped behind the plunger during the filling operation is therefore expelled through the spiral and passages in the plug 16. The cap 39 is provided with a spring member one end of which projects through an opening into engagement with annular slots 45 in the barrel and point section 12 to hold the cap in position. The outer edges of the slots are bevelled to facilitate engagement or disengagement of the spring member.

Title: Improvements in multi-frequency testing
IPC: G01N27/90
Filed: 1960-06-28
Abstract: 908,228. Detecting flaws in metal. MAGNETIC ANALYSIS CORPORATION. June 28, 1960 [Sept. 4, 1959], No. 22622/60. Class 37. In an eddy-current flawdetecting arrangement including a wide range oscillator 4 and a meter 13 for measuring the amplitude of oscillation, coil L1, which together with variable capacitor C1 forms the tank circuit, has closely coupled thereto a winding L2 which is connected by a cable 29 to a detector coil 1, the transformer ratio of the coils being of the order of 100 : 1 whereby the desirably low impedance of the detector coil and cable is matched to the high impedance of the tank circuit. A Hartley oscillator not drawing grid current is preferred to give a linear response, a potentiometer 10 providing means of adjusting the output level. The output is demodulated in unit 6 and amplified in 7 before being applied to centre-zero valve-voltmeter 13. In testing, frequencies are chosen so that changes in inductance L3 arising from causes or defects other than that being sensed are balanced by changes in loss resistance. Curves for the inductance of L3 against the loss resistance at different frequencies are described for outside defects, holes, inside defects and vibrations, in Fig. 4 (not shown). A mathematical analysis is given together with a list of component values. The flaws detected may include dimensional irregularities. The detector may be wound on a polystyrene former, the physical dimensions depending on the size of the test piece, different coils for different jobs having substantially the same impedance. The detector head may comprise a pair of coils screened from each other by an earthed copper plate and supplied simultaneously with different frequencies from duplicate test circuits, or from the same source. Plug-in, multi-step capacitor units providing the variable capacity C1 may be used to facilitate changes of frequency range. Material may be run through the coil 13 at speeds up to 600 feet per minute, and a second indicating or signalling output may be taken from cathode follower stage 7, via a low-pass filter 8.

Abstract: <PICT:0655647/III/1> <PICT:0655647/III/2> <PICT:0655647/III/3> Silicon, titanium and zirconium oxides are produced by decomposing the chlorides with oxygen-containing or oxygeniferous gases at high temperature, the gases passing to the reaction chamber in concentric flow and one at least being in a state of spin.  When both are spinning, the spin may be in the same or opposite direction.  An inert gas, e.g. nitrogen, carbon dioxide or chlorine, or one which is inert only towards the chloride, e.g. hydrocarbons, carbon monoxide, hydrogen or mixtures thereof may be used to separate the reactant gas streams, or it may be fed in around the streams.  Examples indicate a temperature of the various streams varying from 100 DEG  C. to 900 DEG  C.  A variety of nozzles is shown.  In Fig. 2, the outer feed duct 4 is sub-divided by helical partition walls 8, the edges of which may be spaced from the inner duct wall at 10.  The helical walls need not extend to the outlet aperture.  Fig. 5 shows a nozzle of truncated cone structure, the helical walls being not shown.  By varying the angles a  and b  and the distance a, the mixing speed and distance b from the nozzles at which the gas currents contact, may be varied.  Another form is shown wherein helical walls are disposed in the inner duct, and a further form with said walls in both ducts. There is also shown a core-member formed with helical flutes which may be pushed into the central delivery tube.  Three further forms are illustrated, with three concentric ducts, helical walls being disposed respectively in the outer, outer and inner, and all three ducts.  In the last, the intermediate helical walls are opposed in direction to the outer and inner helical walls.
