Filed: 1975-04-23
Abstract: 1501213 Pulsed operation of gas discharge lamps XEROX CORP 23 April 1975 [6 May 1974] 16835/75 Heading H2H [Also in Division G2] A sodium vapour gas discharge lamp 1 is operable from a D.C. source 15 in an intermittent mode for the purpose of photocopying a document 18. Closure of a switch 17 causes a capacitor 16 to be charged from the battery 15 to a voltage which may, of itself, be sufficient to effect a discharge through the lamp 1. In addition a circuit for triggering the lamp when the capacitor 16 is charged to a voltage below the breakdown value of the lamp 1 is provided comprising a winding 21 placed around the lamp 1 to which is applied a pulse from a source 20 to trigger the lamp when desired thus allowing the capacitor 16 to discharge through the lamp. A voltage source 22 is provided whereby the winding 21 may be used to heat the lamp 1 to cause vaporization of the sodium in the lamp.

Abstract: 333,662. I. G. Farbenindustrie Akt.- Ges., and Kaminski, S. May 31, 1929. Presses and clamping devices.-An apparatus for drying and imparting a high gloss to papers such as photographic prints, is characterized by a resiliently-suspended cover-frame adapted to press the wet paper sheets against a flat, easily-exchanged glazing-plate directly mounted on a heating device. In the form shown, the body 1 of the apparatus supports a heating element 2 carrying a glazing-plate 3 bearing the wet paper sheets. Hinged at 5 to the body 1 is a cover frame 4 resiliently supporting by means of spring- encircled bolts 7 a pressure-frame 8 over which are stretched first a metal grating 10, and upon that a soft cloth 11 held in tension by springs. A balancing spring 14 connects the end of the frame 4 to the body 1, and a catch 13 is provided to hold this frame in the raised position. When the frame 4 is closed down, it is held by a locking- device comprising a handle 15 which is secured to a pin 16 slidable in slots 17 in the frame 4, and is connected by a pin 15a to an arm 19 on a snap-latch 18 guided vertically by pins 22, 24, on the frame 4 working respectively against the edge of the latch and in a slot 21 therein. The latch 18 is adapted to engage a hook 20 on the body 1, whereafter pressure may be applied to the prints &c. by depressing the handle 15. The cover-frame is unlocked by raising the handle 15 until the pin 22 reaches a notch 23 in the latch 18, which may then be rocked to disengage it from the hook 20. The glazing-plate bearing the wet prints may be passed between rubber rollers before it is introduced into the apparatus. Several glazing plates are housed in the lower part 3a of the body 1 of the apparatus.

Patent GB-169992-A (GB)
Abstract: 169,992. Allmõnna Industri Aktiebolaget H. T. Cedergren. Oct. 6, 1920, [Convention date]. Time-recorders for morkmen &c.-In apparatus of the individual card type, the card-holder is shifted laterally through one step for each day of the week, and an arresting device for the card is provided to limit its insertion. The operating- lever actuates the usual time-printing mechanism and simultaneously punches a hole in the card with which is adapted to co-operate a finger in the arresting-device and thus serves to regulate the position of the card. The lateral movement of the card-holder 1 is effected by a screwthreaded shaft 4 which is provided with a pinion 6 engaging a mutilated wheel 7 secured to a ratchet-wheel 10 actuated by a pawl 11 on a lever 12 co-operating with a cam 14 rotated once a day by the clock. A spring 17 on the shaft 4 is provided to return the card-holder to its initial position at the end of the week, i.e. when the mutilated part 8 or 9 of the wheel 7 has reached the pinion 6. The card-holder is supported in a stationary member 18 provided with jaws 20, 21. The jaw 20 carries a sliding punch 22 which is operated by a lever 24 and an arm 26 on the spindle 27 of the main operating lever 34. To the jaw 20 is also pivoted a bell-crank lever 28 which extends into the path of the card and which carries a pin 31 engaging a slot 32 in a pivoted member 29 provided with a finger 30 normally held in its elevated position. The first insertion of the card for any day column rocks the lever 28 and moves the finger 30 into contact with the card but without preventing its full insertion; the lever 34 is then operated to record the time and punch a hole. On the next insertion of the card the lever 28 is again rocked but this time the finger 30 enters the previously punched hole and arrests the card for printing the time and punching another hole in a different position in the same column.

Title: Image rejection circuits for superheterodyne receivers
IPC: H03D7/18
Filed: 1948-06-25
Abstract: 654,523. Superheterodyne receivers. STANDARD TELEPHONES & CABLES; Ltd. June 25, 1948, No. 17108. Convention date, Sept. 17, 1947. [Class 40 (v)] A frequency conversion arrangement designed for image frequency rejection comprises a first mixer 11 fed with a signal Fs and with the output Fo from an oscillator 12 to produce a first I.F. which, after filtering at 13, is fed to a second mixer 14 together with the oscillations from oscillator 12 and oscillations Fc from a crystal-controlled oscillator 15. This eliminates the local oscillation Fo, and the second I.F.= Fc - Fs is selected by a filter 17 and fed to the subsequent stages. Oscillator 12 is modulated at a low rate over a band E, but this deviation is, for the desired signal Fs, eliminated at the second mixer 14. For the image signal however, the error is doubled, so that the image I.F. is greatly attenuated by band-pass filter 17. In a modification, the output from the crystal oscillator is mixed with that of the oscillator 12 in a third mixer, a selected output being then fed to mixer 14.
