Patent GB-2315287-A (GB)
Title: Concrete structures having pre-cast columns joined by metal joints
Inventor: O'ROURKE RAYMOND GABRIEL
IPC: E04C3/34
Filed: 1996-08-13
Abstract: Lines of concrete columns (50,60) are cast simultaneously, already interconnected by two-part metal connectors (20,31), with a lower part-connector (20) anchored in or to the top of each lower column (50) and with an upper part-connector (31) anchored in or to the bottom of each upper column (60) of the pair. The columns are then disconnected, by disconnecting the metal connectors, and are stored in a known order so that they can be subsequently reconnected in the same relationship in a concrete structure having concrete floors; that is, each line of vertical columns in the eventual structure are the same columns as were cast in a line to begin with. In the structure itself, after the first level of columns has been erected, the first concrete floor (56) is laid at the tops of the columns, filling a space between the top (55) of each lower column (50) and a plate (21) of the lower part-connector (20), so that the plate (21) is flush with the upper surface (58) of the floor (56) for locating the second column (60) in the line. Then the second level of precast columns is erected, by reconnecting the metal connectors (20,31).

Title: Drive system for a voice control motor
Inventor: BANG HO-YUL
IPC: G11B5/55
Filed: 1996-12-17
Abstract: The voice coil motor 22 of a hard disc drive is driven by the current corresponding to the level of a PWM signal and a current gain selected by a switching operation according to the servo control mode. The change in the value of the gain is delayed for a time (t D , fig 5) following a change in the value of the PWM signal. The aim is to minimise overshoot following a change between track finding and track following modes of operation.

Title: Apparatus and method for regulating power on a contactless portable data carrier
Inventor: HILL MICHAEL JOHN
IPC: G06K19/07
Filed: 1997-01-30
Abstract: A portable data carrier includes a receiving circuit 202 for use thereby in a contactless mode to receive a power signal. The portable data carrier further includes a rectifying element 206 connected to the receiving circuit and having two voltage outputs, whereby the difference between the two voltage outputs reflects an amplitude of the power signal. A comparator element determines the difference between the two voltage outputs and generates a control signal 210 whose amplitude varies substantially proportionately to the difference between the two voltages. A plurality of switchable reactances (e.g. capacitors) C 1 -C 4  are manipulated by the control signal, to thereby effect power regulation and optimization by tuning or de-tuning a resonant circuit disposed within the receiving circuit.

Title: A fastening device for one-way rotation
Inventor: HART DONALD JOHN
IPC: F16B23/00
Filed: 1997-07-07
Abstract: A fastening device 1 has a generally cone-shaped body with steps 7 formed in the sloping flank 6 of the body that face in one circumferential direction only. The steps 7 may be undercut, and may spiral from crown 2 to base 3 in the opposite circumferential direction. Such steps provide abutments for engaging a tool rotated in one direction, but providing no grip for a tool rotated in the opposite direction, thereby providing a fastening device that can not be undone. The device may have a central passage 4, 5 shaped to receive a conventional nut or bolt head, thereby adapting a conventional nut or bolt for rotation by a tool in one direction only. Alternatively the device may take the form of a nut or the head of a bolt. A socket spanner having a socket of complimentary shape to the fastening device 1 is also provided.

Title: Bicycle seat post with spring shock absorber
Inventor: HEWITT PAUL RAYMOND
IPC: B62J1/06
Filed: 1997-12-17
Abstract: The seat post comprises an outer tube 11, for sliding into a bicycle frame tube, and an inner seat support 19 that is slidingly carried in the outer tube on a spring 20. The outer tube has an annular flange (Figure 2) in which four screw threaded cavities that communicate with the interior of the outer tube are formed. The four cavities are positioned at 90 degree increments around the tube in a cross formation. Each cavity receives a grub screw, for example, 28 and 30 that abuts against the support 19 to minimise lateral and twisting movement of the support whilst still allowing it to slide vertically. Locking grub screws, for example, 32 and 34 are also provided to lock the grub screws 28, 30 in position. To further prevent rotation, the support 19 may comprise a non - circular section that slides in a correspondingly shaped part of the outer tube or it may comprise a longitudinal slot which receives a projection from the outer tube. The inner surface of the outer tube may be tapered to accommodate the lateral expansion of the spring under axial compression. A tie rod 23 extends through an axial cavity in the support and the outer tube and is held in place by circlips, for example, 25 that locate in annular grooves. The spring 20 may be replaced with a spring of different rating to accommodate for users of different weight.

Title: Forming capacitor electrodes for integrated circuits
Inventor: YEW TRI-RUNG
IPC: C23C16/24
Filed: 1998-01-12
Abstract: In a method for fabricating a hemispherical grain silicon structure as a bottom electrode of a capacitor in an integrated circuit, poly-silicon is formed as the seed for nucleation instead of amorphous silicon. A silicon oxide layer 24 provided with a contact hole 22 is formed on a substrate 20. The contact hole is filled with polysilicon and patterned to form a capacitor electrode 26. Native oxide on the electrode is removed by H 2  or HCI solution and then, using chlorosilane as a precursor, a hemispherical grain silicon structure 28 is grown on the electrode by CVD to increase its capacitance. The by-products H 2  and HCI of the reaction prevent growth of the structure 28 on the silicon oxide layer 24.

Title: Electrochemical gas sensor with humidifying moisture reservoir at gas inlet.
Inventor: KESSEL ROBERT
IPC: G01N33/00
Filed: 1998-04-22
Abstract: An electrochemical gas sensor 4 has an electrode system for measuring and is directly coupled to the surroundings by way of a gas inlet. In order to reduce the susceptibility to faults and incorrect measurements in the event of fast changes in the air moisture, a moisture reservoir is provided at the gas inlet, which reservoir is designed to reversibly exchange moisture with the gas in order to thus buffer or attenuate fluctuations in the relative moisture of the gas atmosphere which acts on the electrode system. The moisture reservoir can, for example, comprise a container body 3, a porous inner wall 1, and a porous tube 2, coiled between walls 1 and 3, and in which are contained hygroscopic substances. Saline solutions, highly-concentrated acids or silica gel, for example, can be contained in the tubes and draw in moisture from the surroundings if the ambient air moisture rises and release moisture if the ambient air moisture falls.

Title: Quarter wave plate
Inventor: ROWATT CHARLES ANTHONY
IPC: H01P1/17
Filed: 1999-01-15
Abstract: A right circular cylindrical body of an isotropic dielectric such as a cross-linked styrene copolymer, has respective pluralities of mutually parallel grooves 2, 12 formed in its axial end faces, spaced apart by an intermediate portion whose dimension <B>c</B> is a half wavelength. The axial lengths <B>a</B>, <B>b</B> of the grooves are such that when a wave passes through the body, a quarter wavelength phase difference is produced between a component of a wave having its E-vector parallel to the grooves and a component of the wave having its E-vector orthogonal to the grooves. As well as providing the anisotropic properties of the quarter wave plate, the slots are dimensioned to minimise reflections at the end faces. Alternatively the plate may consist of two of more discrete bodies whose grooves are dimensioned to produce a total differential phase shift of one quarter wavelength.
