Title: Filter panel for air, partic. from paint spraying cubicles - comprises a stack of corrugated cardboard between plain cardboard sheets
IPC: B05B14/43
Filed: 1974-03-15
Abstract: A filter panel to be installed between a suction enclosure and e.g. a paint spraying cubicle to filter the air from the cubicle is made from two sheets of plain cardboard parallel to one another with a space between them which is filled with a stack of corrugated cardboard. The sheets of plain cardboard have openings in them but the openings in one sheet are not opposite those in the other. The stack of corrugated cardboard is formed by folding a sheet of corrugated cardboard a number of times. The corrugated cardboard is cut by a number of equally spaced incisions across the corrugations. The area of the stack is less than that of the outer sheets of plain cardboard and a frame is fitted into the peripheral space so formed and made air tight with grease. The filter panel is simple and cheap and is more efficient in avoiding the blocking of suction pipes with paint which occurs with existing units.

Title: Grain table with three screen - has threshing drum adjacent top screen in form of endless belt
IPC: A01F12/44
Filed: 1974-04-08
Abstract: A metal plate (1) feeds the grain to the continuously moving screen (2). This screen is fitted with independent pivotal component attached to a belt or chain running over pulleys. The components have fingers running over protrusions to shake the upper part of the screen. Any untreshed grain which did not fall through the screen with the grain is returned to the drum (3) where it is threshed before being directed to screen (4) which has received the grain from the screen (2). One part of the chaff is removed by auger (5). The grain is blown by fan (7) and falls to screen (6) where it is graded. The remaining chaff is returned to the drum by auger (8), and the grain falls on to sheet (9) to be lifted by auger (10) to the grain tank. A plate in front of the drum causes suction beneath the top screen and also prevents grain being "splashed" out form the drum.

Title: Bicycle derailleur gear automatic cable tensioner - has variable length connection thrusting cable sheath aay from mechanism
IPC: B62M25/04
Filed: 1974-06-05

A locing device (12) secures the connection in the position which it occupier action of the spring (9) thrusting the sheath away when the pivoting portion (2) of the mechanism is in a position corresponding to minimum tension of the cable (1). A third and movable component (18, 19a) acts against the locking device so as to release it temporarily from the connection.

Title: Colour CRT screen with three phosphor elements prodn - is based on coating inner screen surface and photoresist followed by exposure
IPC: H01J9/227
Filed: 1974-07-30
Abstract: The colour cathode ray tube screen has a number of phosphor elements of three types, corresponding to the three primary colours, these phosphor elements being surrounded by a black matrix film of light absorbing material. Prior to the production of the phosphor elements the entire inner surface of the face screen is coated with a photoresistive material. This coating is exposed to light to produce a latent image in the photoresistive layer. This latent image is then developed in order to remove parts of the coating, corresponding to the passive part of the screen. At least this passive part is coated with a light absorbing material, and then the remaining photoresistive layer is removed from the active part of the screen. the light absorbing film may be provided on the passive screen part prior to or after the application of the black matrix film.
