Filed: 1972-07-14
Abstract: 1396346 Photo-electric direction-finders NATIONAL AERONAUTICS & SPACE ADMINISTRATION 14 July 1972 [14 July 1971] 33054/72 Heading H4D In order to determine the azimuth of a transmitter 1, Fig. 1 (not shown), at a receiver 12 when the path therebetween is obstructed the transmitter emits a vertical collimated (e.g. pulsed monochromatic laser) beam and the azimuth of scattered energy is found at the receiver by positioning its boresight axis to intersect the beam. The receiver incorporates a beam splitter 25, photo-multipliers 31, 32, a gate circuit 45 as particularly described and lamps 51, 52, 53. Amplifiers 36, 37 are adjustable in gain to equalize the two receiving channels and to ensure no false triggering of Schmitt circuits 39, 40 by noise. In operation, a communications link is established between the receiver and the transmitter; the boresight of the receiver is approximately aligned with the expected direction; a pulse is transmitted via the link to effect a pulse transmission by the laser; and the receiver is manually rotated until lamp 52 is energized after lamp 51 or 53 has shown whether the transmitter is to the left or right of the receiver's axis.

Abstract: 265,523. British Thomson-Houston Co., Ltd., (General Electric Co.). Nov. 6, 1925. Vacuum tubes; low-pressure metallic-vapour apparatus. - A time lag is introduced by the closure of a switch 18, Fig. 2. and the operation of a switch 4 by causing the switch 18 to complete a charging circuit for a condenser 15 from a battery 16, the circuit being completed by the space current between the cathode 8 and grid 9 of a thermionic valve 1, which may contain an ionizable medium such as argon, helium or mercury vapour. As the condenser becomes charged, the .grid potential changes until the anode current 'becomes sufficient to cause operation of the switch 4. The condenser 15 may be of variable or fixed capacity. In the apparatus shown in Fig. 3, the grid 9 is surrounded by insulation 38 so that the condenser 15 is eliminated; ions slowly collect on the insulation and finally neutralize the effect of the charged grid, whereafter the switch 4 operates. In this arrangement a delay of an hour can be obtained.

Abstract: 486,925. Loom temples. WRIGLEY, J. H., MELVILLE, A., and KELLETT, S. Dec. 9, 1936, No. 33752. [Class 142 (ii)] [Also in Group XVI] A device for expanding fabrics which is applicable in connection with temples for looms, is constructed so that the fabric is led over a continuous surface constituted by a sleeve or band 3 of resilient material, such as rubber, which is moved or capable of moving therewith, and is extended laterally during the leading of the fabric thereover by a force applied to it substantially normal to its surface. The sleeve 3 is mounted on a metal or other hard core or shaft 1, Fig. 1, provided with inclined faces 2, preferably covered with material resistant to liquids or vapours, and the sleeve is also formed with inclined faces 4 preferably of a hard material such as vulcanite. To facilitate the sliding of the inclined faces 4 on the faces 2, the core is slit into segments. The inclined faces slope in opposite directions on each side of the centre of the shaft 1. The ends of the sleeve are sealed by a rubber cap 5, Fig. 1, or may be secured to inclined rings 25, Fig. 12, rotating on inclined bearings 24 on the shaft 1. The expander is preferably used in conjunction with a pressure roller acting over the whole length of the roller, or on the ends only of the roller, or the pressure producing expansion of the sleeve may be produced by the web alone. In a modification, Fig. 4, the sleeve may be connected to the shaft 1 by means of a series of inclined springy rings 8 split into segments, the inclination of the ring segments decreasing from the middle of the ring to the ends of the core so as to cause progressive expansion. The centre of the core has a rubber filling 28. The expansion of the sleeve 3 is arranged to increase progressively in the direction of expansion by arranging the spacing between any pair of inclined faces on the sleeve to be less than the spacing between the corresponding pair of inclined faces on the core, and that the inclination of the foces to the axis of the core decreases towards the ends of the core and sleeve. The inclined faces may be of ring or helical form.
