Title: Dimensionally stable thermoplastic open-ended tubular articles
Inventor: WATSON MARTIN JOHN
IPC: B29C49/64
Filed: 1985-03-18
Abstract: Apparatus for making open-ended thermoplastic tubular articles, which are dimensionally stable up to elevated temperatures comprises a fixed, heated external mould (12) and cooled mandrel (10), which is vertically displaceable relative to the mould (12). An open-ended polymer tube is disposed between the mandrel and mould and both its ends clamped to restrain the tube axially. The polymer tube is radially expanded into contact with the hot mould and maintained in contact for a time sufficient to ensure dimensional stability, and then allowed to shrink back into contact with the cooled mandrel, which is maintained at a temperature below the glass transistion temperature of the polymer. The resulting article is then stripped from the mandrel.

Patent GB-2182222-A (GB)
Title: Optical fibre testing
Inventor: BYRON KEVIN CHRISTOPHER
IPC: G01M11/00
Filed: 1985-10-18
Abstract: An optical time domain reflectometry (OTDR) system which uses optical amplification in a fibre under test to provide a means of selectively increasing the backscatter at a particular point along the fibre length. A pump pulse ???p is launched in the fibre (9-Figure 1) and after a set delay a signal pulse ???s is launched into the fibre. (This assumes that the group velocity of the signal pulse is greater than that of the pump pulse. If it is less, the signal pulse is launched first). The difference in wavelength between the two pulses is one Stokes shift. In view of dispersion in the fibre the signal pulse will catch up with the pump pulse and be amplified. The backscatter trace will thus exhibit a corresponding peak (12) where the pulses overlap, thus the backscatter is amplified. By varying the delay between the pump and signal pulses, corresponding sections of the fibre may be examined. <IMAGE>

Title: Piston dosing pump for a fluid
Inventor: RYSCHKA MARTIN
IPC: F04B15/08
Filed: 1986-10-03
Abstract: A pump has a compensating vessel 7 off the inlet duct 2 leading to the pumping chamber 6 between the pistons 4,5. In operation, liquid will find its way in to vessel 7 and some will automatically be given up when not enough to fill chamber 6 is supplied directly down duct 2. This is particularly useful when pumping low-boiling liquids such as anaesthetics which can vaporise under the low pressure of the inlet stroke. Preferably the vessel 7 is in the form of metallic bellows. <IMAGE>
Patent GB-2181336-A (GB)
Title: An absorbent article having dual cuffs
Inventor: LAWSON MICHAEL I
IPC: A61F13/15
Filed: 1986-10-10
Abstract: An integral disposable absorbent article such as a diaper having a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, at least one elastically contractible gasketing cuff, and at least one barrier cuff. The barrier cuff has a proximal edge and a distal edge. The absorbent article is additionally provided with spacing means for spacing the distal edge away from the top surface of the topsheet. In addition, adhesive means secure the end portions of the barrier cuff closed. A channel is formed between the proximal and distal edges in at least the crotch region because the distal edge is spaced away from the topsheet top surface.When the diaper embodiment of the present invention is applied to a wearer, the barrier cuff rides up along the inner thighs and the perineum of the wearer in the crotch region and along the buttocks in the back waist region. Leakage prevention is enhanced because body exudates which are not immediately absorbed by the absorbent core contact the barrier cuff and are contained and held within the channel so that they do not wick out of the diaper or flow out of the gaps between the diaper and the legs or waist of the wearer. Additionally, should such exudates flow beyond the barrier cuff, leakage is further enhanced by the gasketing cuff because it forms an additional fluid impervious barrier about the leg or waist of the wearer.

Title: Frequency converters
Inventor: OKANOBU TAIWA
IPC: H03D7/18
Filed: 1989-04-19
Abstract: In an RF receiver, fabrication of most of the components on an IC chip IC is facilitated by converting the received modulated information signal SFM to an IF signal S6 with all the modulation components by mixing at 32,33 SFM with local oscillator signals S5, S4 from oscillators 26, 16 having a relative phase shift, e.g. 90', and the outputs S2, S3 are phase shifted at 34, 35 so that image signal components present in S2, S3 become mutually out of phase and the phase shifted signals S2', S3' are combined fit 36 and filtered at 512 or 61 to derive the IF signal S6. The received signals may be FM or AM and selectable via switches 91-93 and filters 51,61 responsive to a mode selection voltage Sb. The output of filters 51 or 61 is supplied to an output 72 via an associated demodulator 541 or 63. Saturation of mixers 32,33 and demodulators 54,63 is avoided by variable gain amplifiers 31, 53, controlled by AGC circuits 81, 82. A pre-IF converter may additionally be included at the front end when received signals are at a very high frequency e.g. to receive audio signals accompanying VHF TV signals. The receiver provides good image component rejection and stepes separation and low distortion and beat interference. …<IMAGE>…

Patent GB-900596-A (GB)
Abstract: 900,596. Automatic control systems. RANK PRECISION INDUSTRIES Ltd. Aug. 7, 1958 [Aug. 13, 1957], No. 25528/57. Class 38 (4). [Also in Group XL (c)] An electronic circuit has a rest state between an upper and a lower limiting state to enable it it to be used as a " dead zone " device in a servo mechanism. The Specification describes apparatus having input/output characteristics shown in Fig. 1. Fig. 3 shows a circuit in which a cathode-coupled pair Via, V1b is coupled via a cathode follower V2 to an output terminal, full negative feed-back normally being provided via a diode bridge D1 so that the output is normally zero. When the input voltage at terminal I rises above value D (Fig. 1) the diode bridge D1 becomes non-conductive, breaking the negative feed-back path so that the circuit is controlled by a positive feed-back path via variable resistor RV2. Valve Via becomes heavily conductive so that the output reaches its negative limiting value E. The circuit remains in this state until the input voltage is reduced to value C when the diode bridge D1 becomes conductive once again, connecting the full negative feed-back so that the output drops to zero. A similar action occurs when the input voltage is reduced below point B. Zener diodes D7, D8 provide output limiting. The datum output level in the rest condition is adjustable by variable resistor RV1. The extent of the dead zone i.e. the voltage between points A and C, is adjustable by variable resistor RV2. Fig. 4 shows a similar circuit in which the common emitter pair of transistors Q2, Q3 are coupled to emitter followers Q1, Q4, the output being provided from the emitter follower Q5, coupled to the collector of transistor Q2 by means of a Zener diode D5. Automatic control systems.-The invention is applicable to the prevention of hunting in a servomechanism controlling the screw motor in a rolling mill.
