Title: Monoclonal antibody
Inventor: GOODENOUGH PETER WILLIAM
IPC: C12N9/50
Filed: 1986-08-15
Abstract: Papaya peptidases A and B are separated from a crude latex extract of the unripe Carica papaya fruit on an anionic ion-exchange resin, whereas previous methods have used cationic resins. The resulting enzymes are sufficiently pure to allow highly specific antibodies to be prepared. Two hybridoma cell lines secreting such monoclonal antibodies have been deposited. The antibodies can be used to detect levels of the enzyme in food and drink. The enzymes themselves are also useful medically, for degrading slipped discs.

Patent GB-2241130-A (GB)
Title: Optical duplexer
Inventor: WALKER ROBERT GRAHAM
IPC: H04B10/25
Filed: 1990-02-20
Abstract: A guided wave optical duplexer is described, in which there is provided a four-port duplexer with the property that light of a first wavelength and polarization input to Port 1 is substantially routed to Port 2 (the balance to Port 4) while light of a second wavelength and polarization input to Port 2 is substantially routed to Port 3. This invention concerns the provision of means whereby light of the first kind reflected from an interface beyond Port 2, may be prevented from reaching Port 3. The technique used involves interferometry of light reflected from Port 2 with that from the complementary output at Port 4, requiring only the provision of a 90 DEG  phase-shift between these outputs at the reflective interface. This is achieved either by angling the interface or by using curved waveguides.
Patent GB-2241278-A (GB)
Title: Securing housings to conduits
Inventor: NEILL KENNETH
IPC: F16B2/10
Filed: 1990-02-23
Abstract: An arrangement for attaching a tap-box (10) to a conduit (16) of a busway power distribution system comprises a pair of jaw-members (23, 24) adapted to be moved in and out of engagement with flanges (18, 20), formed along either edge of the conduit (16), by operation of an actuating member (38). When the jaws (23, 24) are open, the actuating member (38) obstructs closure of the door (12) of the box (10), such that an electrical power switch interlocked with the door is in its "off" position whenever the box (10) is being attached or detached from the conduit (16). When the actuating member (38) is moved to close the laws (23, 24) then the door (12) may be closed. In a second embodiment the jaws of the mechanism are each provided with fastening boils which engage lugs affixed to the surface of the box when the jaws are closed. In each embodiment the mechanism may be operated from the front of the box, and all moving parts move closely adjacent a surface of the box so that only limited clearance is required adjacent the surface to accommodate the mechanism. The arrangement may also be used in other applications, such as attaching enclosures for motor starters to arrays of busbars in a motor control centre. <IMAGE>

Title: A sequence control mechanism employing the gear mechanism
Inventor: TAKASHI WATANABE
IPC: G11B15/18
Filed: 1990-03-09
Abstract: A sequence control mechanism has a drive gear 18 and an arm 19 pivotally mounted on the same shaft 5. A transmitting gear 20 is mounted on said pivot arm and in engagement with said drive gear. At least one partly toothless gear 23, 24 or 25 having a toothed portion is so positioned in the pivotal path of the transmitting gear that engagement of the toothed portion with the transmitting gear stops the transmitting gear idling. A first mechanism e.g. a head plate (9) is driven by the partly-toothless gear and acts to return the partly-toothless gear to a position in which said toothed portions are in the path of said transmitting gear. A second mechanism e.g. a tape take up reel 3 or supply reel 4 which, when said transmitting gear has passed by said toothless portions of said partly-toothless gear, engages with said transmitting gear and is driven thereby. This mechanism makes it possible to perform sequence control and switching of the rotating direction without use of the clutch mechanism or the electromagnets used in the prior art. <IMAGE>

Title: Vehicle position monitoring
Inventor: STEVENS MICHAEL CHARLES
IPC: G01S5/06
Filed: 1991-05-22
Abstract: In a method for determining the location of a vehicle (10), a transmitter on the vehicle emits an identifying signal pulse at a random trigger rate. The signal pulse has a fast leading edge to reduce multi-path signal effects and the random trigger rate permits a large number of vehicles to be identified whilst avoiding repeated synchronous emission of identifying signal pulses. Receivers (16, 18) and associated circuitry are provided to monitor identifying signal pulses and to determine vehicle location by monitoring signal pulses received at two receivers (16,18) relative to a known path (12) of the vehicle (10) or at three receivers and by using trilateration. A method for synchronising receiver clock pulses is disclosed. <IMAGE>
