Title: Negative resistance integrated circuit - has two MOS FET's with specified gate connections for switching nide change-over
Inventor: GRUODIS ALGIRDAS J
IPC: H03H1/00
Filed: 1975-11-04
Abstract: The complementary metal-oxide-semiconductor technology is used to produce an integrated circuit with a negative resistance characteristic under voltage application to a given circuit region. A metal-oxide-semiconductor transistor of a first channel type has its gate connected to the switching nodes and its source-drain path in series with a load to operating voltage source. A second such transistor of opposite channel type has its source-drain path connecting the switching node to the operating voltage source terminal, coupled to the load. This second transistor gate is connected to the junction point of the load and the first transistor. Thus the application of a voltage to a given region at the switching node the source-drain path of the second transistor becomes conductive.

Title: Disinfection of air in a closed room by inertia filters - centrifugal blowers incorporated, keep room at higher pressure
Inventor: JOUBERT JACK DANIEL PROF
IPC: A61L9/03
Filed: 1975-12-12
Abstract: The air in a room with closed windows and doors is cleansed of any micro-organisms released into it, without pollution of the outside atmos. by filtration in a closed circuit. The air issues from the filter at a relatively highly pressure, as a 'curtain' in front of the wall apertures, - windows, door, connecting the room with its surroundings. The infected air of the room is replaced by air from outside purified by filtration, and escapes due to its higher pressure through the wall apertures mentioned. The closed circuit filtration is effected by device extending beyond the full width of and fitted above the wall apertures, whilst the inlet for the air from outside is located at a point of lowest pressure. Removes bacteria from the centre of the room without allowing them to pollute the outside atmosphere. Supplies a relatively large quantity of sterile air at an economical price. Works without noise.
