Patent BG-52080-B2 (BG)
Title: Reagent and method for the modification of graphite electrodes
Inventor: DENCHEV ZHIVKO I
IPC: G01N27/333
Filed: 1990-06-20
Abstract: The reagent and the method are used in the flow injection inversion volt-ampere analysis (FIIVA) for the determination of metallic ions in water solutions. Films, resistant in a wide range of acidities of the aqueous medium and applicable in a wide range of operating potentials are produced on the graphite electrodes (GE), which determines their high selectivity to metallic ions having close electrochemical relations (ions of precious metals). Furthermore, they are lasting, gas impermeable and have even thicknesses. The GE modification reagent is disulphide of dithiophosphate having the general formula /(RO)2PSS/2 where R means alkyl or aryl radical. By the method the modification reagent and GE are placed in a vessel for vacuumization. The reagent is molten at vacuum of 10-13.5 HPa and temperature from 95 to 100°C, and the smelt produced covers the operating part of the electrode which remains in it for 2-3 hours. Then the GE is removed above the smelt and is tempered to 20-25°C at the same vacuum.

Title: Pulse transformer drive with thyristor switching - uses rectifier input to charge capacitor for half cycle pulsing and second thyristor to short other half cycle
IPC: H02M1/08
Filed: 1971-02-01
Abstract: Rectifier input triggering circuit for a thyristor used to drive a pulse output stage of an input switching stage, esp. for a vibrator drive. A.C input (1,2) is rectified (3) and charges a capacitor (10) via a current limiting resistor (5) and voltage stabilising Zener diode (6). When the capacitor (10) is fully charged the voltage rises on the trigger of the unijunction (9), to a point determined by the potential divider (7,8), so that it triggers and discharges the capacitor (10) through the primary of the output transformer (19). Output is produced for a positive input and during the negative input half cycle the capacitor (10) is short circuited by a diode (15) and transistor (12) or single transistor circuit. (OS).

Abstract: PURPOSE:To make a proper function attainable even in time of wrong operation happening in a light switch, by installing a control transistor which is turned to On in time of making the light switch into a lighting position of a light body. CONSTITUTION:A control transistor 6, a first timer 5 and a second timer 7 are installed altogether. When a light switch 2 is selected to an ON-terminal 2a, a driving relay 3 is energized with current via an OR circuit 4. And, with excitation of an exciting coil 3a, a contact 3b is selected to an up-terminal 3c and feeds a driving signal which drives a light body to situate an upright position. With this constitution, the light body shifts from a housing position to the upright position and comes to a stop. Likewise, the light body is lighted by this operation. At this time, the control transistor 6 is as well turned to ON, with which a driving transistor 5a of the timer 5 is also turned to ON whereby a condenser C1 comes into a state of being charged as well. On the other hand, the timer 7 keeps an off-state.

Abstract: By combining a pad having a repositionable adhesive with a carbonless imaging system, multiple copies of a writing on the top sheet of the pad are provided. These features have application in pads for memos, interoffice correspondence, and notes. A user may select the desired set of copies by removing the required number of sheets from the pad. If a divider is provided with each pad, e.g. a cardboard or a hard insert sheet, the multiple pages are imaged before they are removed from the pad by inserting the divider into the pad after counting the appropriate number of sheets to be copied. Thus, the divider prevents copying and imaging throughout the entire pad.
