IPC: B42D5/04
Filed: 1963-11-21
Abstract: 1,020,905. Filing papers. J. EVERSHED & CO. (BOW) Ltd., and W. W. EVERSHED. Oct. 21, 1964 [Nov. 21, 1963], No. 46077/63. Heading B6E. [Also in Divisions A4 and G3] An assembly of sheets 1, e.g. calender sheets, with registering perforations 2, 3, is held together by threading a loop 7 of a cord 5 through the perforations and passing the free ends of the cord through the loop 7, the free ends being provided with an enlargement, e.g. by means of a knot 6, which prevents the free ends being withdrawn from the loop when the cord is tightened as by hanging the assembly from a support.

Title: Aircraft lift-producing members
IPC: B64C9/24
Filed: 1975-10-08
Abstract: 1492177 Aircraft high-lift flaps BRITISH AIRCRAFT CORP Ltd 8 Oct 1975 [17 Oct 1974] 46146/74 Heading B7G An aircraft wing 1 having a high-lift leading edge flap 2 is formed at spanwise-spaced intervals with arcuate tracks 5 each guiding a roller 6 mounted on the rear end of a rod 7 which provides at its forward end a mounting for the flap 2. An intermediate cylindrical portion 7a of the rod slides within a fitting 8 pivotally mounted at 9 on a wing bracket 10 and formed with arms 14 each having a slot for a roller 15 mounted on the leading portion 11 of the wing. The leading portion 11 comprises a flexible upper skin 12 which extends around the leading edge into a lower skin portion 13 abutting a fixed skin portion 16. When the rollers 6 are moved forwardly in their tracks the rods 7 are moved through the fittings 8 which tilt about pivots 9 causing the flap 2 to move to the extended drooped position shown by full-lines. Simultaneously tilting of fittings 8 and associated arms 14 causes wing nose portion 11 to droop downwardly by deflection of skin panel 12, thereby forming slot 17. The invention may be applied to the forward region of a pivotable lift-increasing flap.

Title: Copper activated metaphosphate phosphors
IPC: C09K11/71
Filed: 1964-11-12
Abstract: A strontium metaphosphate phospor is activated by copper which is preferably in the cupric valency state.  The metaphosphate may be either Sn3(P3O9)2 or Si5(P3O10)2.  From 0.001 to 0.1 mole of copper per 2 moles of PO3 may be present.  The phosphor may be formed by firing, in an oxidizing atmosphere (e.g. air), a mixture of a cuprous compound (e.g. Cu2Cl2) with monobasic strontium phosphate and/or ammonium phosphate and a strontium compound which thermally decomposes to form the oxide (e.g. SrCo3).  Firing may take place between 1000 DEG  and 1900 DEG F  The phosphor may be used in a high-pressure mercury vapour lamp at temperature of about 350 DEG C., and may be alpha or beta phase.  Excitation and emission wavelengths are given (Fig. 2).

As described, the width of the screw head 15 may be sufficient to take up the distance between the cheeks 16, 17 (Fig. 2). Alternatively a brass cup 14 may be interposed therebetween. The spring support may be snap fitted in a slot 10 in a terminal plate 3, the terminal plate 3 being mounted in a junction block 1 and holding sockets 2. The screw terminal may effect electrical connection between an eyelet terminal 8 and the socket 2.

Title: Battery charges
IPC: H02J7/00
Filed: 1972-10-11
Abstract: 1437092 Battery chargers LUCAS BATTERIES Ltd 17 Aug 1973 [11 Oct 1972] 46777/72 Heading H2H A battery charger comprises a thyristor 22, a Zener diode 29 for sensing a voltage representative of the voltage of the battery 17, an amplifier 31, 34 responsive to the Zener diode and providing gate current to the thyristor, and a circuit for modifying the voltage sensed by the Zener diode during charging of the battery so that the battery charges to a first value whereafter the charger maintains the battery voltage at a second value lower than the first value. If the battery is in a discharged condition, the Zener diode is non-conductive so that the transistor 31 is switched off whilst the transistor 34 is switched on to supply gate current to the thyristor 22. The battery is therefore supplied with charging current from the transformer 10 and rectifier 14. The conduction of the transistor 34 also causes conduction of a transistor 39 which, via diodes 41-43 and resistors 25, 26. lowers the anode voltage of the Zener diode 29. The battery charges to a relatively high voltage before the Zener diode conducts to cause the transistor 34 and therefore the thyristor 22 to switch off. The transistor 39 is also switched off so that re-charging of the battery cannot begin until the battery voltage has fallen to a relatively low value.

The lifting mechanism incorporates cables 70 attached to centrally pivoted levers 68 on each side of the trough. The ends of shaft 72 carry locking lugs 76 engaging locking upper portions 21 of the forked brackets 15, and locating lugs 77 engaging the inner faces of said brackets. Each container is built up from plates to form a channel-shaped trough divided into compartments 52, 53 by an inner partition 54, is closed at one end 30, and tapers at the discharge end 36 to a width equal to that of the separate compartments. After tilting the trough, a door pivoted to the bottom of the discharge end is released by pulling a cable 51 attached to spring-loaded bolt 49, freeing the dependent portion 47 of a spindle 45 carrying catches holding the door which then swings open as the contents of compartment 52 discharge. Cable 60 is then pulled, rocking catch lever 58 to release door 56 which swings across to the dotted line position, Fig. 3, as material discharges from compartment 53. In a modification, Fig. 11 (not shown), the compartments are mutually inclined so that the outer sides are straight throughout their length up to the discharge end 36, allowing the accommodation of exceptionally long pieces of scrap metal in one of the compartments. The troughs 23 have a capacity up to twelve times greater than that of the conventional charging boxes and with several lorries in use a furnace may be charged through all the doors simultaneously.

In a vidicon tube having an electrostatic focusing lens 7, 8, 9, as shown, and a support ring electrode 11 for the final grid 10 having a diameter D equal to that of the final electrode 9 of the lens, there are the following relationships between D; a, the width of the gap between electrodes 9 and 11; and b, the axial width of the electrode 11: a = 0À034-0À046 D and b = 0À11-0À16 D. Also the voltage applied to electrode 11 equals 1À8-2À2 times that applied to the electrode 9. Other relationships are as follows: P = 1À93-2À37 D; q = 0À7- 1À05; and L = 2À0-2À5 D, where P is the distance between the centre of deflection M and the surface of the grid 10; q is the distance between the centre of deflection M and the centre Q of the lens 7, 8, 9; S is the internal diameter of the focusing electrode 8; and L is the axial width of the magnetic deflection coils 12. Pin-cushion distortion of the raster introduced by the magnetic deflection coils is arranged to compensate for barrel-distortion introduced by the high potential of the final grid.
