Title: Antenna assembly for radio circuit and method therefor
Inventor: MOLLER PAUL J
IPC: H01Q1/36
Filed: 1994-02-14
Abstract: An antenna assembly (100), and associated method, for a radio, such as a portable radiotelephone, which is of minimal physical dimensions and which is operable over a wide range of frequencies. A length of wire (106) is helically-shaped and includes at least a portion of winding. A capacitive top-hat (136) is positioned at an end portion of the wire. By increasing the number of windings of the wire (106), the height of the antenna assembly is reduced, but such reduction also reduces the size of the bandwidth of frequencies over which the antenna assembly is operable. Increase in the size of the surface area of the capacitive top-hat (136) increases the size of the bandwidth over which the assembly is operable. Selection of the top-hat size and the number of windings permits both physical dimensions of the antenna assembly and the size of the bandwidth to be selected. <IMAGE>

Title: Methods of assaying data-repairing enzymes and their alkylated derivatives
Inventor: LI BENJAMIN FUK LOI
IPC: C12Q1/48
Filed: 1995-01-13
Abstract: The present invention provides methods of assaying the human DNA repair enzyme O<6>-methylguanine-DNA methyltransferase (MGMT) and/or active site alkylated derivatives thereof (R-MGMT), which rely on the ability of a protease, e.g. V8 Protease (also referred to as Glu-C Protease), to distinguish between these two enzyme forms. Such a method comprises the steps of: (a) contacting the sample with a protease to which one of human MGMT and R-MGMT is preferentially sensitive; and (b) determining whether the treated sample contains one or more polypeptides selected from (i) at least one polypeptide fragment characteristic of action of the protease on the protease-sensitive form of human MGMT and (ii) the protease-resistant form of human MGMT.

Title: Non-azo 1,8-naphthalimide dyes for the detection and quantitation of a paramagnetic metal cation in a non-aqueous medium
Inventor: LEWIS DAVID E
IPC: C09B57/08
Filed: 1993-11-12
Abstract: The use of a class of non-azo 1,8-naphthalimide dyes for the detection and quantitation of a paramagnetic metal cation in a non-aqueous medium and some of the dyes that will complex with a paramagnetic metal cation. The concentration of the paramagnetic metal cation is determined by monitoring differences in the detected fluorescent emission spectra of the non-azo 1,8-naphthalimide dye solution when it is mixed with paramagnetic metal cations present in the non-aqueous medium. The detected fluorescent emission spectra will vary in relation to the presence or amount of the paramagnetic metal cation in the mixture.

Title: Door lock with snib mechanism
Inventor: FORTUNE GEOFFREY JAMES
IPC: E05B55/14
Filed: 1993-10-08
Abstract: A dual function lock mechanism includes a body 30, 32, FIG 1, and a cam member 40, 41 mounted on the body for rotation about an axis, and a retractor 36 adapted to drive a latch bolt and supported for sliding movement transversely with respect to the said axis. Means 41 is provided to slide the retractor in a first direction to retract the latch bolt from a latch position to a release position. By virtue of respective cooperable mutually engageable formations 41, 72 on the cam member and on the retractor means, a clockwise rotational movement of the cam member slides the retractor in a direction opposite the said first direction to move the latch bolt from the latch position to an extended lock position, and a predetermined opposite rotational movement is effective to return the latch bolt from the lock position to the latch position. Detent 64 is provided to engage and thereby normally prevent the retractor from moving the latch bolt from the lock position to the latch position. An automatically releasable privacy snib mechanism 140, FIG 13, temporarily locks an outside knob 16a against operation and includes a spring-loaded snib plate 142 and a button 150 for setting the plate which is automatically released on rotation of the inside knob 16". <IMAGE>

Title: Fluid couplings
Inventor: MORRISON LEIGH WAYNE
IPC: F16L37/084
Filed: 1995-03-10
Abstract: A fluid coupling (1) comprising releasably interconnectable male and female coupling members (2, 3) for interconnecting fluid flow lines. The male coupling member (2) has an inlet end (7), and an outlet end (8) connectable to a fluid flow line, whilst the female coupling member (3) has an inlet end (10) for axially receiving the inlet end (7) of the male coupling member (2) and an outlet end (11) connectable to another fluid line. A locking mechanism (13) is provided to exert a retaining influence on the male coupling member (2), when received within the female coupling member (3), so as to releasably interconnect the coupling members (2, 3). A lock release mechanism (33) is selectively operable to remove the retaining influence for the locking mechanism (13). That in turn releases the coupling members (2, 3). The lock release mechanism (33) has release member (34) which is manually movable in a non-axial direction to operate the lock release mechanism (33) by the threads (39, 40) to move the lock release sleeve (35) axially. That operation removes the retaining influence of the locking mechanism (13) to allow disconnection of the coupling members (2, 3).

Title: Hydraulically damped mounting device
Inventor: BOAST DAVID
IPC: F16F9/342
Filed: 1997-10-03
Abstract: A hydraulically damped mounting device, particularly for a vehicle seat has a partition which defines a working chamber 17 and a compensation chamber 23, and with a variable cross-section orifice 19. As shown, a spool 33 attached to boss 1, and which has outer portions 37, 41 of cross-section increasing away from a central portion 35, moves in the orifice. Alternatively the orifice may be an iris diaphragm; the area may be changed by use of an electrorheological fluid and electrodes adjacent the orifice. Thus in the event of shock, as fluid is forced between the chambers, the area through which fluid can pass is reduced, eg by movement of the spool, thus varying the damping effect.

Abstract: An extrudable or calenderable composition especially for hot melt thermoplastic welding rod use, comprises a mixture of polyvinyl butyral and 3-25 wt.% [based on the two polymers] of a polymer having a polar moiety which can hydrogen bond with the polyvinyl butyral. The composition does not stick to hot metal parts. Suitable such polar polymers listed are ethylene-[meth]acrylic acid polymers, poly[ethylene-vinyl acetate], polyamides, polyamines, thermoplastic polyurethanes, PVA, polylethylene-carbon monoxide], and mixtures thereof. Conventional additives may be included, as can a further non-reactive polymer and examples of the latter include ethylene-propylene rubbers such as EPDM, polyolefines, polyethylene terephthalate and polyether ketones. These can constitute up to 50 wt.% of the composition provided they do not cause sticking to metal parts. The invention also envisages welding rods made from these polymers and a surface covering comprising the composition eg flooring.

The printhead is movable relative to the apparatus between a print position (Fig.2a) at which printing is effected and a user accessible position spaced therefrom (Fig.2b). The apparatus is configured so that the mount can be withdrawn away from the printhead. The withdrawal operation causes the printhead to move from the print position to the user accessible position.

Title: Voltage controlled oscillator
Inventor: MCDONALD NEIL ANDREW
IPC: H03K3/0231
Filed: 1998-05-23
Abstract: A phase-locked loop having a phase detector and a voltage controlled oscillator is provided for a smart card. The voltage controlled oscillator has a comparator (40), a switch (48) and a capacitor (50). The capacitor (50) charges when the switch (48) is open. When an input voltage (44) and a reference voltage (46), both of which are supplied to the comparator (40), are equal, the comparator (40) produces an output signal (42) to close the switch (48) and discharge the capacitor (50). Between an input to the comparator (40) which is used to supply it with the input voltage (44) and the capacitor (50) there is provided a resistor (66). Voltage is dropped across the resistor (66) so that the comparator (40) produces the output signal (42) when the sum of the voltage drop and voltage at the capacitor (50) equals the reference voltage (46). In this way, delays within the voltage controlled oscillator can be compensated for and ideal operation across its frequency range can be obtained.
