Title: A baling press
IPC: B30B9/30
Filed: 1981-02-26
Abstract: A baling press of vertical or horizontal construction comprises a ram (2) moving to and fro in a press cell (3) to compress introduced waste material against a latchable door (6) and optionaliy means (10) to prevent a springing back of the bale layers compacted in successive operating steps. An electronic proximity switch (15), provides a signal which prevents a return stroke of the press ram (2) on the production of a compacted bale of desired dimensions. The switch (15) is inserted flush, in one of the side walls (3d) to face inwardly of the press cell (3) and detects the movement past the switch of a metallic vane (16) or the like fastened to the ram (2) at an appropriate spacing from its working face. The free end (16a) of the vane (16) in the case of a finished bale lies in the region of the active switching zone of the switch (15). <IMAGE>

Title: Production of viral antigens
IPC: C12N7/08
Filed: 1981-06-29
Abstract: Antigens specific to respiratory syncytial virus are produced on the surface of cells by: (1) culturing in vitro cells derived from a human or animal mucosa, (2) inoculating the cultured cells with respiratory syncytial virus, and (3) selecting virally infected cells from the culture. The resulting cells or the viral antigen(s) when partially or completely isolated from the cells have immunological and diagnostic uses in respect of infection by respiratory syncytial virus and may be used to isolate viral antibodies. A specific cell strain NM7 produced by this method from bovine nasal mucosal cells has respiratory syncytial virus antigens on its surface and its corresponding, uninfected cell strain NM5 can be infected similarly.

Inventor: PUNWANI DHARAMVIR
IPC: C10G1/00
Filed: 1981-07-18
Abstract: Peat is dried in a fluidized bed using gases from a subsequent hydropyrolysis of the dried peat. The dried peat is subjected to hydropyrolysis with hot gases produced by subsequent gasification of the char residue from the hydropyrolysis. The gasification of the hot char is carried out in a fluidized bed at above 1700 DEG F with steam and oxygen and the hot gas product is passed directed to the hydropyrolysis zone. The hydropyrolysis is carried out for a gas residence of 2-10 sec at 1000-1600 DEG F, 200-600 psia total pressure and 60-150 psia hydrogen partial pressure to produce gases and liquid hydrocarbons from which gasoline and fuel oil can be produced.

Title: R. F. Circuit
Inventor: BATES ROBERT NEIL
IPC: H03D7/14
Filed: 1982-08-27
Abstract: An R.F. circuit, for example an R.F. mixer circuit comprising an insulating substrate (3) in an E-plane of a rectangular waveguide (not shown) comprises an first portion including a (quasi) TEM transmission line (15, 13) for propagating R.F. energy at substantially different first and second frequencies (L.O. and I.F. respectively) and a second portion including a waveguide for propagating R.F. energy at the first frequency (L.O.). Between the waveguide and the transmission line (15, 13) area filter (14) for passing the first frequency (L.O.) and blocking the second (I.F.), and a mode transducer (11). To inhibit the mode transducer (11) from acting as a stub weakly coupled via the filter (14) to the second portion of the circuit at the second frequency (I.F.), but without affecting coupling at the first frequency (L.O.), stub means (27-30) substantially short-circuit the mode transducer (11) adjacent the filter (14). When the second frequency (I.F.) is much less than the first (L.O.), the stub means may comprise a stub (27) which is a quarter wavelength long at the first frequency (L.O.), and hence much shorter at the second frequency (I.F.), and which is short- circuited at its free end (28) by a conductive connection through the substrate (3). <IMAGE>
