Title: A method for the inhibition of scale deposition and composition therefor
Inventor: HEN JOHN
IPC: C09K8/528
Filed: 1993-08-05
Abstract: A method for the inhibition of scale deposition on the surfaces of a well coproducing oil and scale forming brines compris-ing injecting into the well reservoir an acidic aqueous solution at a first pH containing dissolved therein a scale inhibitor, multiva-lent metal ions, and a heat-sensitive pH-increasing substance containing no more than 10 carbon atoms, which decomposes at elevated temperatures liberating an alkaline compound such that the solution is inherently heated by the higher ambient reservoir temperature  to a temperature at which the alkaline compound is liberated from the heat-sensitive substance thus raising the pH of the solution to a point at which a sparingly soluble multivalent metal salt of the scale inhibitor is phase separated from the solu-tion on the porous surfaces of the reservoir rock formation, providing for a slow release of inhibitor into the produced brines when the well is in its production phase.

Title: Shaving systems
Inventor: WAIN KEVIN JAMES
IPC: B26B21/24
Filed: 1993-10-08
Abstract: A shaving system comprises novel components of a razor handle (1), a razor blade cartridge (2), and a magazine (5) holding a supply of cartridges. The handle and magazine are adapted to cooperate so that a used cartridge on the handle is replaced by (i) inserting the used cartridge into an empty maga-zine compartment, which unlatches the handle from the cartridge; (ii) moving the handle along the magazine towards a next adjacent compartment accom-modating a fresh cartridge, firstly to disconnect the handle from the used ear-tridge which is left in its compartment and secondly to latach the handle onto the fresh cartridge held in the next compartment; and (iii) withdrawing from the magazine the handle with the fresh cartridge attached. Thus, the cartridges are dispensed from the magazine in turn with each cartridge replacement op-eration being effected by a single stroke of the handle relative to the magazine, this stroke having distinct components of insertion, advancement and withdra-wal. A novel handle and cartridge coupling system is used, the cartridge hav-ing key elements (14) which engage in slots (15) provided on the handle so that the handle is connected to the cartridge by displacement relative thereto in a direction transverse to the cartridge and substantially parallel to its front face (25), and latch devices (18) which engage in notches (17) at the ends of the car-tridge being provided on the handle to lock the cartridge against detachment from the handle. Conveniently, the latch devices and notches (17, 18) define a pivot enabling pivotal movement of the cartridge on the handle.

Title: Broadband mobile radio system
Inventor: FRANK MATTHIAS
IPC: H04B7/26
Filed: 1996-09-30
Abstract: A mobile radio system and means therefor are proposed to permit broadband radio transmission in which a mobile station (MS) can be assigned a plurality of subscriber channels (TCH) of different widths.            To accomplish this, concentrators (SMX) are connected to the base stations (BS, BS') of the mobile radio system and to the mobile station (MS). These concentrators (SMX) operate in an asynchronous transfer mode to combine a plurality of subscriber channels (TCH) into one transmit channel (DL) by statistical time-division multiplexing and to separate a receive channel (UL) into the plurality of subscriber channels (TCH) by statistical time-division demultiplexing. This provides a broadband wireless link between the mobile station and the base stations which is characterized by a flexible number of subscriber channels that can have different widths.            In one embodiment of the mobile radio system according to the invention, the base stations (BS, BS') operate in a common-channel mode and are connectable with the mobile station (MS) via directional radio links (P, P'). Through this combination of common-frequency working, directional radio, and ATM, the invention can be used to advantage in the mobile radio field.
