Title: Broadcasting system
Inventor: BAKER HENRY LOUIS
IPC: H04L9/16
Filed: 1985-02-04
Abstract: A multi-channel broadcasting system in which encrypted data signals are transmitted in either or both directions between a central terminal 1 and any one of a number of subscriber terminals 2. When a subscriber selects a secure channel dedicated to the transmission of encrypted data, the terminal is temporarily connected to a further channel dedicated to the transmission of encryption and/or decryption information signals. The transmitted encryption and decryption information signals are stored in the terminals 1 and 2 respectively and used to encrypt and decrypt the data signal to be transmitted after the terminal is switched back to the selected secure channel. The stored encryption and decryption information signals are subsequently cancelled. <IMAGE>

Patent GB-2223509-A (GB)
Title: Vapour phase processing
Inventor: ANTELL GEORGE RICHARD
IPC: C30B25/14
Filed: 1988-10-04
Abstract: A bubbler as illustrated in Fig. 2 (11) for solid reactant sources (18) such as trimethylindium for use in chemical vapour deposition includes a gas port (14) and a dip tube (16) in a chamber, the dip tube extending substantially from one end of the chamber to the other. Carrier gas such as hydrogen enters the chamber (12) via the port (14) and the output gas, which also includes vapour from the solid reactant material (18), exits the chamber via the dip tube (16). This is the reverse flow direction to that employed in conventional bubblers and leads to a more stable output. To prevent the entrainment of solid particles the dip tube may be of a wide bore dimension and/or a filter (20) may be incorporated therein. The bubbler is immersed in a constant temperature water bath and the bath temperature determines the vapour pressure of the solid reactant source. In use with hydrogen as the carrier gas and trimethylindium (TMIn) as the solid reactant source the hydrogen concentrates at the top of the chamber since it is less dense than the H2 - TMIn mixture formed as a saturated mixture in equilibrium with solid TMIn and will begin to force the H2 - TMIn downwards. <IMAGE>

The opposite end of the shaft has a movable stop, eg a spring metal retaining clip 30 which can be depressed, to allow that end of the shaft to enter or be withdrawn freely from the rung, but which normally projects to act as a further stop at the adjacent end of the shaft 21. In another embodiment, the movable stop is a pivotable member with a slot about the pivot, so that it can lie along or transverse to the shaft. Notches 26 and 36 may be depressed into the upper surface of the shaft 21 for positive location of a paint pot or similar narrow-handle item. <IMAGE>
