Title: A device for inducing slack in a wrapping film, associated with means for conveying packs of rolls
Inventor: CINOTTI ANDREA
IPC: B65B25/14
Filed: 1992-10-16
Abstract: In a machine for packaging rolls 4 of household paper products, the packs are restrained between groups of vertical teeth 5 associated with a conveyor passing from a wrapping station 1 through a folding station and a heat seal station; by equipping the wrapping station with additional vertical teeth 8 fixed to a support 9 afforded by the machine, which are offset from the conveyor teeth 5, a tighter restraint can be applied as the rolls 4 are raised so as to be enveloped initially in the relative sheet 2 of wrapping film and gripped between the fixed teeth 8 and one group of conveyor teeth 5, whereupon the movement of those conveyor teeth in direction A beyond the station will reduce the grip and thus allow the sheet to slacken, and the rolls to regain their normal shape. <IMAGE>

Title: Wideband constant impedance amplifiers.
Inventor: LAWTON RODNEY JAMES
IPC: H03F1/34
Filed: 1992-10-28
Abstract: A family of wideband amplifier circuits using series and shunt feedback over two stages to achieve constant impedance, including single-ended, single-ended input/differential output and differential input/differential output forms. The voltage gain of a single-ended amplifier is effectively the open-loop voltage gain of the input transistor, 1. To provide constant impedance the valve of the resistance 4, which applies feedback from the output transistor 2 to the base of a further transistors, is equal to the required output resistance. Resistors 3, 6 providing respectively feedback to the base of the input transistor and connection from the output of the input transistor to the control electrode of the further transistor are respectively greater, smaller than the required output resistance by a factor equal to the open-loop voltage gain. <IMAGE>

Title: Method and apparatus for running a mechanical roller arm centralizer through restricted well pipe
Inventor: KINLEY KARL S
IPC: E21B17/10
Filed: 1993-07-16
Abstract: A roller arm centralizer has two sets of arms 31, 32 which are biassed outwardly by springs 28 and have casing engaging rollers 40 at their junctions 36. A first set of arms 31, 32 carry a lower set of rollers 40 spaced evenly around the centralizer but staggered from each other in the axial direction. Similarly a second set of arms carry an upper set of axially staggered rollers. This arrangement reduces the force necessary to move the centralizer through a casing restriction. A flange 39 on spring housing 26 is located between stops 37, 38 to limit the extension and retraction of the arms. In a second embodiment (not shown) the sets of arms have independent biassing means and in a third embodiment a cam arrangement ensures that the biassing means exerts an outwardly directed force when the arms are fully retracted. <IMAGE>

Title: A signal processor
Inventor: MCEWEN ROBERT KENNEDY
IPC: H04N5/365
Filed: 1994-11-29
Abstract: A signal processor (10) receives both open and closed field values for elements of a detector (11) and corrects for non-uniformities in offset between the elements prior to converting the signal to a digital signal via an A to D converter (15). The corrected signal is then digitally processed to compensate for linear and higher order non-uniformities in the response of the element. The invention enables the A to D converter to have relatively low resolution for a given output radiation. <IMAGE>

Title: Gas discharge lamp drive circuit; dimming
Inventor: AARONS DAVID JOHN
IPC: H05B41/392
Filed: 1997-05-07
Abstract: A gas discharge lamp 4 is driven by a high frequency pulse train formed by combining a first pulse train with a second pulse train. The two pulse trains may be generated by respective inverters with input drive signals P0, P1 and output transformers T0, T1 having secondaries TP30, TP40 and TP31, TP41 connected in series with one another across the lamp 4. The circuit has a high power factor and may be used for driving a lamp at a steady power, but is particularly intended for dimming metal halide or sodium vapour lamps, or especially fluorescent lamps. A digitized dimming control signal causes the phase of drive signal P0 to be shifted relative to drive signal P1, signals P0 and P1 being in phase for 100% light output and 180 degrees out of phase for 0% light output (Fig.2), so that the outputs from transformers T0, T1 combine to drive the lamp with pulses having a width dependent on the dimming level (Fig.5). Secondaries TP10, TP20 and TP11, TP21 provide high frequency lamp filament heating currents which remain steady irrespective of the dimming level. The circuit may be used to dim a 2.44 m (8 feet) long fluorescent lamp to less than 1% of full light output.

Title: Fibre optic strain gauge
Inventor: UCHIYAMA HARUYOSHI
IPC: G01M11/02
Filed: 1997-10-14
Abstract: An optical fibre strain measuring apparatus detects the strain at an arbitrary distance within a test optical fibre 124, and facilitates the detecting of the back scattered light, comprises an acousto-optic switch 108 which outputs a measuring pulse light, an optical circulator 112 which conveys the pulse to an optical ring circuit incorporating optical fibre 124, while allowing the natural Brillouin back scattered light generated from the fibre 124 to travel anticlockwise through the optical ring circuit and become amplified. Frequency conversion means 132 successively converts the reference light output from optical directional coupler 102 into a reference pulse train which has its frequency changed into a step form, and acousto-optic switch 134 outputs the reference pulse train as a sampling pulse. The sampling pulse and the Brillouin back scattered light from the optical ring circuit are converted into electrical signals by conversion means 138, and signal processing means 146 measures the strain of the test fibre 124 using these signals.
