Title: Electroluminescent lamps
IPC: H05B33/14
Filed: 1954-01-08
Abstract: 780,162. Electroluminescence. SYLVANIA ELECTRIC PRODUCTS, Inc. Jan. 8, 1954 [Jan. 9, 1953], No. 649/54. Drawings to Specification. Class 39(1). An electroluminescent material comprises a host crystal of one or more of the sulphide, selenide or silicate of one or more of the metals cadmium, zinc, calcium or strontium, an activator e.g. copper, manganese or silver, and a donator consisting of one or more of the metals thallium, indium or tin. Zinc oxide may be included in the host crystal e.g. zinc sulphide, up to an amount of 25 per cent thereof, as may zinc chloride. The donator material is between 0À00005 and 0À0000005 gram atom per mole of host crystal. The presence of activator and absence of donator in certain parts of the host crystal are said to produce depletion layers of higher resistivity than the donator-containing material, which are locations of high field density. These layers are produced by chemical treatment of the fired powder with acetic acid or ammonium acetate, the two being successively ground together with increasing dilution of the acetic acid or the acetate, finally rinsing with pure water. Other ammonium salts may be used. Zinc sulphide activated with copper and containing zinc oxide is stated to give greenish yellow luminescence at 60 cycles/sec. and blue luminescence at 2000 cycles. The electroluminescent materials may be mixed with or embedded in dielectric material, e.g. nitrocellulose or castor oil, and enclosed between conductive electrodes, either reflective or transparent, or disposed between two conductor wires wound side by side or between conducting coatings formed on insulating supports, Figs. 1-5 (not shown).

Title: Improvements in or relating to re-cocking or re-charging devices for machine guns
IPC: F15B13/02
Filed: 1941-01-23
Abstract: 546,859. Recocking machine guns. CLEVELAND, F. J. (Bendix Aviation Corporation). Jan. 23, 1941. No. 939. [Class 92 (ii)] Relates to hydraulic piston- and-cylinder means for recocking or recharging machine guns, and consists in providing a control valve which is so arranged that it also acts to prevent the escape of pressure liquid from the cylinder when it is desired to hold the breech block in a rear safety position. In the form shown, a piston and - cylinder power device 20, Fig. 1, operates on a pin 14 projecting from the breech bolt for retracting the breech bolt to clear a jam and feed a fresh cartridge. Pressure liquid is supplied to a pilot's control valve 72 by a pump 60 feeding an accumulator 56 which serves a pressure inlet pipe 68. The control valve enables pressure to be supplied to the power cylinder 20 by pipe 28 to extend a piston member 32 against the action of a spring 34 which returns the piston, the liquid then passing through pipe 28 control valve 72 and pipe 80 back to a reservoir 50. The pilot's control is by a push knob 90, Fig. 3, on a spindle 88 which opens port 70 and admits pressure to pipe 28 through a spring-controlled check valve 356, Fig. 5. The valve is kept open by a spring-urged pin 366 kept in raised position by an eccentric 89 on the spindle 88 which is retained in the inward position by a detent 100. When the pressure acting in the cylinder 20 has opened the breech, the pressure builds up and acts through port 106 to press the spindle 88 to the left to close the pressure inlet and permit exhaust past the check valve and through pipe 80 to reservoir 50, such exhaust taking place as the piston rod 32 returns under the action of the spring 34. To render the firing mechanism safe and inoperative, the knob 90 is turned through 180 degrees to rotate the spindle 88 and again pressed inwardly, the eccentric 89 then permitting the check valve to seat, Fig. 6, and act as a non-return valve. This precludes free exhaust of liquid and prevents the return of the piston rod so that, through the pin 14, the breech is held in open position.

Title: Method and device for depositing and packing felt
Inventor: TONII ESU PIOTOROUSUKII
IPC: B65B63/02
Filed: 1984-01-04
Abstract: An improved apparatus for collecting and stacking insulation batts or other similar articles and transferring these collections into one of a plurality of packing or compression chambers. The apparatus has a batt-transfer device that operates in a horizontal reciprocating motion, moving a first collection of batts from a collecting surface to a position in a packing chamber located on either side of the collection surface, and cycling back for another collection. Lifting members in each chamber raise the stack up to a predetermined height and holding fingers are inserted underneath this collection to hold them in place. The lifting members then cycle back down to the floor or bottom of the chamber for successive loads with the holding fingers being alternately extended and retracted in sequence to retain the successively larger collection of batts. When one chamber is completely full and a compression plate begins to force all the batts into a smaller unit, the reciprocating batt-transfer device starts transferring insulation batts into another packing chamber on the opposite side of the collection surface. After the compression plate forces the batts into a smaller, more compact unit, a ram pushes this unit through a snout and into a waiting container.
