Title: Detonators loading process - using reduced amt of secondary explosive
IPC: F42B33/02
Filed: 1970-04-29
Abstract: The cases are driven into dies by force; this not only secures their correct positioning but provides support against the compression forces transmitted by the punches for loading pri. and sec. explosives. The wall thickness may also be reduced to between 20/100 and 25/100 mm instead of greater than 40/100. Priming powers equivalent to those of detonators loaded in the conventional manner can be obtd. with about one half the normal amt. of sec. explosive; higher compression leads to better moisture resistance and reduces the risk of misfires.

Title: Busbar transmission system for binary data - uses multiplexer to stop control signals to switch emitters
IPC: H04J3/10
Filed: 1974-05-03
Abstract: A transmission bus is composed of conductors (L) connected to the outputs of transmitters. Each transmitter (E1-n) has three operating states, behaving in the 0 and 1 logic states as low internal impedance generators and presenting in the third state a very high internal impedance. Each transmitter possesses an input for receiving the data to be transmitted and another input for controlling data transfer to the transmission bus. The data and the control commands are time multiplexed from a base signal of a multiplexing unit (UM). At the start of each base signal, the multiplexing unit emits a transmission authorization signal which invalidates control signal transmission for each transmitter by a time interval sufficient to envelope the transitory period corresponding to the disconnection of the transmitter during transmission and to the connection of the transmitter which must transmit.
