Abstract: 1,065,243. Aircraft take-off instruments. SMITHS INDUSTRIES Ltd. May 12, 1964 [May 16, 1963], No. 44062/66. Divided out of 1,065,242. Heading B7W. An aircraft instrument for use during takeoff comprises first and second indices 1, 2 formed on tapes 6, 7 which are linearly movable in response to two signals respectively dependent upon the distance travelled along the ground by the aircraft and a prediction of the increased distance that will need to be travelled in order to attain a predetermined and constant increase in the forward velocity of the aircraft, whereby the relative positions of indices 1 and 2 indicate to the pilot the difference between the distance already travelled and that which needs to be travelled in order to achieve a safe take-off. The instrument display is divided into regions 3A, 3B, 3C, 3D by cursors 11, 12 and tapes 6, 7 extend diagonally across, each having an area 8 of one colour and an area 9 of another colour, the junctions 1 and 2 respectively of such areas constituting said indices. Each of these four elements is driven by a servomechanism responsive to an analogue output signal from a digital computer similar to that of Specification 909,175. Tape 6 is driven so that the displacement of its index 1 from a datum position in the bottom left-hand comer represents S, the distance travelled along the runway from the beginning of the ground run. The position of index 2 on tape 7 similarly represents SI, the predicted distance to be travelled to obtain a predetermined and constant increase (for example ten knots) in the forward velocity of the aircraft. The significance of the location of the index 1 in the regions 3A-3D is that in region 3A it is not safe to continue if an emergency arises, but it is safe to abandon take-off. In region 3B these operations are respectively safe and safe, in region 3C safe and unsafe respectively, and in region 3D unsafe and unsafe respectively.

Abstract: 1,204,508. Static inverters. SOC. DES PROCEDES MODERNES D'INJECTION SOPROMI. 29 Sept., 1967 [30 Sept., 1966], No. 44564/67. Heading H2F. In a fuel injection system for an I.C. engine an electromagnetic injector coil 6 (Fig. 5) forms with a capacitor 5 an oscillatory circuit the frequency and amplitude of oscillation of which is regulated as a function of the quantity of fuel to be injected per unit time, whereby fuel is fed as a series of minor injections rather than a single large injection. L6, C5 are in the diagonal of a thyristor switching bridge controlled by a multivibrator 207 so that Th201 and Th203 are fired simultaneously to conduct one half cycle of the oscillatory current and are then quenched while Th202, Th204 are made to conduct the succeeding half cycle and so on. At the end only of each half cycle a pulse of current from a battery 7 is fed by a transistor 205, controlled by a unit 211, to sustain oscillations and in addition controls the oscillation amplitude and thus the open period of the injector. Thus the maximum oscillatory current passes through a diode 206 and not through the battery. The multivibrator controls the frequency of injection. Alternatively, one thyristor in each pair may be replaced by a diode Figs. 6, 7 (not shown). In addition (Fig. 7, not shown) two injector coils may be alternately connected to the capacitor by the thyristors.

Title: Manufacture of Laminated Articles.
Inventor: WOOLER ALAN METCALF
IPC: B29C44/24
Filed: 1966-10-10
Abstract: 1,164,323. Foamed laminates. IMPERIAL CHEMICAL INDUSTRIES Ltd. 27 Sept., 1967 [10 Oct., 1966], No. 45196/66. Heading B5N. A laminate having a core of foamed plastics or resinous material between two outer facing sheets is formed by applying to one of the sheets a priming layer of foam-forming material and allowing the foaming reaction to proceed, applying thereon a second (main) layer of foamforming material and again allowing foaming to proceed, bringing the second sheet into place while the main foam layer is still tacky, and applying pressure to the laminate whilst curing the foam core. Apparatus for carrying out the process is also described and claimed. Preferably foaming should take place more rapidly in the priming layer, e.g. by application of heat or use of a highly-catalysed foam-forming mixture, in order to minimize the time lag necessary between applying layers. The second layer is preferably applied after the priming layer has developed sufficient mechanical strength to avoid mixing of layers. The priming layer may be used as an adhesive to secure side members, in the form of strips, each by one edge to the margin of the lower facing sheet, thus preventing overflow of the mixture subsequently applied, or to secure reinforcing members, e.g. conduits, or to seal joints between panels of the lower facing. The foam may be polyurethane foam, and the facing materials may be lengths or sheets of paper, wood, plastic, metal, rubber, paperboard, plasterboard, asbestos, bitumenimpregnated paper or roofing felt. As shown, the lower facing sheets in the form of panels 2 are carried on paper sheet 1 fed from a supply roll. Foam-forming mixture is applied from mixing and dispersion heads 3, 6, the reaction in the priming layer being accelerated by infrared heater 5. Rollers 10, 12 cause a continuous sheet of upper facing material to be fed under conveying surface 11. Conveying surfaces 11, 13 are backed by adjustable platens 17, 18 and heated by infra-red heaters 15, 16; the foam is thus cured while pressure is applied via roll 12 and platen 17. The mixing and dispersion heads 3, 6 are mounted for lateral travel across the direction of movement of the panels 2.

Abstract: 1,075,297. Valve and transistor amplifying circuits. LOSENHAUSENWERK DUSSELDORFER MASCHINENBAU A.G. Nov. 10, 1964, No. 45720/64. Headings H3T and H3W. In an amplifier for following a pick-up device 1 of high impedance, e.g. comprising reactance 3 shunted by high resistance 4, the input impedance is increased by means of both positive and negative feedback. In each case the feedback is derived from a separate potentiometer 15 or 16 across the output of the amplifier, the positive feedback being applied to the grid directly and the negative feedback to a resistor 8 in the cathode circuit, to which the grid leak 7 is returned. According to the invention the positive and negative feedback are adjusted to near but slightly less than equality. Any remaining lack of constancy of response with frequency may be corrected by means of a suitable RC potentiometer network (Fig. 2, not shown) connected to the amplifier output: alternatively a valve with a frequency-compensating RC network as its anode load may follow the amplifier (Fig. 3, not shown). It is stated in the Specification that transistors may be employed instead of valves.

In one embodiment having three disc packs each with 20 disc faces, each block of data in a string corresponds in length to one track on a disc. Assuming module 0 has a first available track at cylinder 2, face 5, the first 15 blocks of a string are recorded on faces 5-19 of cylinder 2 and the next 5 blocks of the string are recorded on cylinder 3 starting at face 0, for example. Blocks 20 are recorded in module 1, for example at first available cylinder 5 of faces 10-19 and cylinder 6 of faces 0-9. Similarly blocks 40-59 are recorded in module 2 at first available cylinder 1 of faces 4-19 and cylinder 2 of faces 0-3. This arrangement may require head movement for each group-of 20 blocks, depending on the location of the first available face in each module. In a second embodiment, blocks are recorded in succession on the first available faces in each module taken in turn and head movement only takes place if overflow from the last module occurs. Taking the same example as above, blocks 0-14 are recorded in module 0, cylinder 2, faces 5-19; blocks 15-24 in module 1, cylinder 5, faces 10-19; blocks 25-39 in module 2, cylinder 1, faces 4-18; block 40 in module 2, cylinder 1, face 19; blocks 41-59 would then be recorded in module 0, cylinder 3, faces 0-18. Algorithms for calculating the addresses of the various blocks in storage are described.
