Preparation of way-bills.(a) Way-bills should neatly written out by carbon process and signed in full by the issuing clerk, care being taken to get clear and legible impressions in all the foils. The name of the forwarding station should be stamped on each foil except in cases where the name of the forwarding station is printed on the waybills themselves, and the destination station should be written in full block letters. When articles referred to in para 902 are booked, full description of the contents should be given on the way-bill. The num ....etc

The HEF4543B is a BCD to 7-segment latch/decoder/driver for liquid crystal and LED displays. It has four address inputs (D0 to D3), an active LOW latch enable input (LE), an active HIGH blanking input (BL), an active HIGH phase input (PH) and seven buffered segment outputs (Qa to Qg). The circuit provides the function of a 4-bit storage latch and an 8-4-2-1 BCD to 7-segment decoder/driver. It can invert the logic levels of the output combination. The phase (PH), blanking (BL) and latch enable (LE) inputs are used to reverse the function table p ....etc

Luggage Security System

While traveling by a train or bus, we generally lock our luggage using a chain-and-lock arrangement. But, still we are under tension, apprehending that somebody may cut the chain and steal our luggage. Here is a simple circuit to alarm you when somebody tries to cut the chain. Transistor T1 enables supply to the sound generator chip when the base current starts flowing through t. When the wire (thin enameled copper wire of 30 to 40 SWG, used or windi ....etc

SCR is abbreviation for Silicon Controlled Rectifier. SCR has three pins anode, cathode and gate as shown in the below figure. It is made up of there PN junction diodes also; it is solid state equivalent of gas filled triode and has around four semi conductor layers. SCR can conduct the current in a single direction or we can say SCR s are unidirectional. The SCR can be triggered only at the gate through the current. SCR will combine the features of rectifier and transistor. They are mainly used in switching applications. They can also be trig ....etc
