Patent GB-2198846-A (GB)
Title: Improvements relating to diagnostic techniques, in particular for the detection of precancer
Inventor: SINGER ALBERT
IPC: G01N33/50
Filed: 1986-12-12
Abstract: A precancerous condition is marked by a raised molar concentration of octadeca-9, 11-dienoic acid (18:2 (9,11)) in tissues, cells and other cell lipid fractions. The mechanism by which this isomer of linoleic acid (18:2 (9,12)) is produced is uncertain but may be due to free radical activity. The ratio of the molar concentrations of the 9, 11 and 9, 12 isomers has also been found to be raised in the precancerous condition. The diagnosis of the precancerous condition may thus be facilitated by ascertainment of the molar concentration of the 9, 11 isomer, or by ascertainment of the ratio of the molar concentrations of the 9, 11 and 9, 12 isomers, in tissue and cell samples; and by comparison with the 9, 11 isomer concentration, or the concentration ratio of the 9, 11 and 9, 12 isomers, found in normal tissue and cells.

Title: Associative record storage cell
Inventor: TURVEY DOUGLAS PHILIP
IPC: G11C15/04
Filed: 1989-05-23
Abstract: A content addressable storage cell comprises (Fig. 1): a memory which can store an entire data record; a communications unit which allows communication between the cell, a parent cell and a child cell; and a control unit which controls the communications unit and the memory and can perform operations upon data passed between them and responds to commands passed from the parent cell. The cells are connected in chains on a child to parent basis to a host (Fig. 2). All cells are connected by a REGAIN line which enables the host to regain communication with all cells in the chain. After being issued the search command, the control unit of each cell performs the comparison itself and acts upon the result without intervention from the host, thus allowing all cells to operate simultaneously (in parallel). <IMAGE>

Patent GB-2240894-A (GB)
Title: Detecting vehicles with low radar cross sections
Inventor: HOWIE ROBIN MIDDLEMASS
IPC: G01S13/04
Filed: 1990-01-24
Abstract: The detection technique is based upon the fact that if a vehicle with low radar cross section passes between a source of radar energy and a suitable radar receiver, the location of the vehicle can be detected by virtue of the reduced radar energy received from the vehicle as against that received from the radar source. To increase the area covered by such a system, an extended radar source could be created by illuminating the ground below a high altitude aircraft carrying the radar source and a receiver. Alternatively the radar source may be formed by a large number of ground based radar transmitters and the radar receiver(s) may be at a high altitude.

Title: Remedial device for retracted nipples
Inventor: CARTER DAPHNE VALERIE
IPC: A61H9/00
Filed: 1990-02-09
Abstract: The invention relates to a nipple extractor for remedying nipple retraction. The nipple extractor comprises a teat- shaped enclosure (1) of resilient material. This has a base with an opening and flat rim (3) for pressing against the periphery of a retracted nipple with substantial exclusion of air. The enclosure has collapsible side walls (4) and the end of the enclosure remote from the base is completely air-tight or has only a restricted opening for expulsion of air. The end of the enclosure is provided with handle means (5, 6) for pushing the said end towards the base to cause outward distortion of the side walls and partial expulsion of air from the enclosure, and for subsequently pulling the said end away from the base to create suction inside the enclosure. <IMAGE>

Title: Fluid flow control governor
Inventor: SPRINGER GERALD ALFRED JOHN
IPC: G05D16/06
Filed: 1990-02-13
Abstract: A governor has a fluid inlet port (11), an outlet port (15) and a movable valve member (62) provided with resilient sealing means (64) engageable with a cooperative seating (53). A spring (59) biases the valve member into engagement with the seating (53) preventing fluid flow, the valve member (62) being movable by a diaphragm (30) which is acted upon by a frusto-conical spring (43), the biasing force of which can be adjusted by a manually operable member (40). The governor can thus act as a conventional governor but with the addition of the sealing element can also act as a valve to prevent fluid flow between the inlet and outlet. <IMAGE>

Title: Apparatus for filtering and coalescing liquids
Inventor: COSGROVE RONALD CHARLES
IPC: B01D35/10
Filed: 1990-08-01
Abstract: A tubular, inward flow filter element 3 comprises fibres extending between lower support 5 and upper support 6 which is axially and rotatably movable to compress the fibres in the filtering position and to separate them in the cleaning position. So that pore size decreases in the flow direction, both the fibre spacing and the unconstrained length of the fibres decreases inwards.

Title: Push-pull inverter
Inventor: KIJIMA SEIICHI
IPC: H05B41/282
Filed: 1990-10-15
Abstract: In a push-pull inverter including a boosting or step-up transformer 30 having a secondary coil 30s for connection to a load 11 e.g. a discharge tube, switching elements 13, 14 conduct alternately to enable or interrupt the current flow through associated primary coil sections 30p1, 30p2 and have a capacitor 31, 32 connected between their control electrodes through which a load current flows when a positive feed-back circuit activates 13, 14 alternately. During one half cycle, current flows through load 11, secondary 30s, base-emitter of 13, capacitor 32 and back to load until 13 saturates when it is turned off and a reverse current flows through 14. Instead of 31, 32, a single capacitor may be connected between bases of 13, 14. Transistors 13, 14 may be cross-coupled via further capacitors to avoid instability when load 11 is removed. A resonance capacitor 33 whose need is obviated by present invention may be optionally connected across the primary to improve shape of output waveform. A transistor 18 supplies bias currents when enabled by power switch 17. With such an arrangement, a feed-back coil is not required and a resonance capacitor is only optional. <IMAGE>

Patent GB-2243966-A (GB)
Title: Active filters
Inventor: DE VEIRMAN GEERT A
IPC: H03H11/12
Filed: 1991-03-19
Abstract: A biquadratic transconductance-C filter includes a differentiator in the feed forward path of the input signal to compensate for the non-ideal operation of the transconductance elements 21, 25 and to simplify the performance requirements of a variable gain amplifier K1 also in the feed forward path. The variable gain amplifier and feed forward technique are used to create two programmable magnitude, opposite signal zeros on the real axis, whose effect on the incoming data signal results in variable pulse slimming. The addition of a differentiator C1', 36 in the feed forward path eliminates the effect of the output admittance of the transconductance elements on the filter's group delay. The differentiator acts as a first order, high pass filter. The 3db frequency of the differentiator is controlled so that the input signal is attenuated before it is provided to the variable gain amplifier. This reduces the dynamic range requirements of the variable gain amplifier without affecting group delay requirements. The filter includes at least two transconductance elements 21, 25 connected to each other as shown in the feed-forward and feed-back directions. Various types of differentiator for use in the filter are disclosed. <IMAGE>

Title: Improvements in cladding for thermally insulated pipe bends
Inventor: CARTER ROBERT DENNIS
IPC: F16L59/22
Filed: 1991-05-03
Abstract: A unit (10) for fitting around thermally-insulated pipework of curved configuration is composed of a pair of symmetrically curved components (11, 12) with inner surfaces of semi-circular profile. The components (11, 12) separate along the unit 10 and have side margins (13, 14) which are stepped to overlap and form depressions (18) running around the unit. Rivets or screws (19) fit in bores in the side margins and locate within the depressions (18) so as not to extend beyond the inner peripheral surface (9) of the unit. In this way there is no danger of penetrating a vapour seal barrier which may be placed around the insulation. Alternatively the edges may be joined by interlocking folds. <IMAGE>
