Title: Gas-liquid contactor
IPC: B01F33/40
Filed: 1981-03-04
Abstract: The gas-liquid contactor, e.g. a reactor or a spray-drier for slurries is of the kind having a contactor body 1 with its axis directed substantially vertically, a throat 2 formed in the lower or upper part of the body and having an inside diameter smaller than that of the body, a cyclone provided below or above the throat and larger in inside diameter than the throat, and a nozzle shaft 4 held substantially vertically in the throat or cyclone.

Title: Rectifying column
IPC: B01D3/26
Filed: 1981-12-31
Abstract: The rectifying column (1), primarily intended for vacuum operation, contains a number of exchange stages (2) for steam and liquid, in which an atomized layer (3) is produced and is brought into contact with steam by repeated circulation of the liquid to be rectified. The liquid is sprayed into the space, free of built-in components, of the individual exchange stages (2) through nozzles (4) which are mounted in the wall (5) of the rectifying column (1). The sprayed droplets are removed in each exchange stage (2) by a droplet catcher (12) and are led into a collecting channel (9). A pump (11) outside the exchange space draws the liquid to be rectified from the collecting channel (9) and returns it to the spray nozzles (4). An alternative horizontally arranged column omits the droplet catcher 12 since the droplets fall directly into collecting channels within the column which are separated by weirs decreasing in height from one end of the column to the other. <IMAGE>

Title: Novel silyl derivatives
Inventor: CROSSLEY ROGER
IPC: C07F7/18
Filed: 1983-06-15
Abstract: New silyl derivatives of 5,6,7,8- tetrahydroquinolines are substituted at the 8-position by the group SiR3 where R may be one of various hydrocarbon groups or an electron donating substituent. The 8-position may also carry a lithium, sodium or potassium atom. The new silyl derivatives may be prepared by treating a corresponding 8- lithio, sodio or potassio tetrahydroquinoline with a silyl halide R3SiHal followed by a metal compound R*M where M is sodium, potassium or lithium and R* is alkyl, cycloalkyl, aralkyl or aryl or an amine residue. The new silyl derivatives are useful intermediates for the preparation of known 5,6,7,8-tetrahydroquinoline-8-nitriles, amides and thioamides employing an alkyl silyl isothiocyanate or cyanate. The nitriles and thioamides are anti- ulcer agents. The Related compounds may be made by analogous methods, and are also new.

Filed: 1983-06-24
Abstract: A method for levying charges for passenger transport which involves automatic decrementing of a purchased travel entitlement, which is encoded on an object such as a magnetically-readable card, in accordance with journey times rather than distances. When the traveller presents the object to the appropriate automatic apparatus at the start and finish of a journey, the encoded travel entitlement is reduced according to a predetermined function of the times of presentation. The object, which may be inspected in the course of a journey with the aid of portable apparatus, is not validated for travel unless the initial presentation has taken place, and the encoded entitlement continues to expire should the traveller fail to present the object at the end of the journey.
