Filed: 1971-11-30
Abstract: 1369048 Producing fibre-reinforced material; drawing G RAU 30 Nov 1971 [2 Dec 1970] 55633/71 Headings B3A and B3P [Also in Division E1] A method of producing a shaped element of fibre-reinforced material comprising a plurality of aligned fibres embedded in a matrix comprises the steps of inserting a wire into a jacket of a matrix material, subjecting the jacket to mechanical working to reduce the cross-sectional area, arranging a plurality of such jacketed wires in a bundle, and subjecting the bundle to further mechanical working to reduce the crosssectional areas of the wires and jackets and to cause bonding together of the jackets to form an homogeneous matrix. The bonded wires and jackets, which preferably are made of metallic materials, may be enclosed in an outer casing of the matrix material and may also be provided with an inner core of said material. In an example, a copper-coated alloy steel 3, Fig. 1, is embedded in a pure silver matrix 4 and subsequently the individual jacketed wires 2 are drawn down to fit into a thin-walled silver casing 1, the resulting element being drawn down further as required. In an alternative embodiment, jacketed wires of steel 2, Fig. 9, of square cross-section, and a silver sheet 5 are arranged in a rectangular tube 1 of silver which is drawn through stepwise reducing dies to form the shaped element. The wires may be arranged  in various ways in the matrix material, e.g. parallel to each other, helically disposed, and cylindrical, rectangular and other cross-sectional shapes of elements may be produced.

Abstract: 1368820 Modulating light HEWLETTPACKARD CO 2 Dec 1971 [28 Dec 1970] 56036/71 Heading H4F In apparatus wherein a plane polarized light beam 14 is passed collinearly with an acoustic wave S through a birefringent medium 11 so that a narrow optical band (at a frequency determined by the acoustic frequency, according to a phase matching condition) is diffracted into the orthogonal polarization and transmitted by an analyser 17, if the acoustic phase velocity vector is collinear with the optical path, the acoustic group velocity vector may be at an angle thereto whereby the acoustic wave tends to "walk away" from the optical path reducing the effective coherence length and the effectiveness of the interaction. In such cases it is now proposed to render the optical path and the acoustic group velocity vector collinear. Fig. 3, illustrates a case where the wave S from a transducer 18 is reflected at a surface 12 of medium 11 into collinearity with the optical beam 14, the medium 11 preferably being surrounded by a fluid 23, and the angle of face 12 for collinear optical and acoustic group velocity vectors is derived. The incident angle # 1  for the beam 14 depends on the fluid 23 used, and is approximately the desired Brewster angle for water 23 and crystal quartz 11. In Fig. 4 beam 14 and wave S are both transmitted through a medium 24 and face 12 into medium 11 and again derivations of the various angles are given. Medium 24 may be fused quartz or YAG for crystal quartz 11, or YAG with crystalline LiNbO 3  11, and the assembly may be operated for example, in air or a silicone oil bath depending on the required optical transmission.

Abstract: 1440987 Stretch levelling drive I UNGERER 6 Dec 1973 [7 Feb 1973] 56479/73 Heading B3E [Also in Division G3] In an arrangement in which a strip of material 3 is guided under stretching traction over a plurality of rolls 1, 2, e.g. in a metal stretchstraightening machine, the drive or braking of one of the rolls is controlled in response to the difference between the variation in elongation that occurs as it passes over a roll and a desired value for this quantity. In the embodiment the elongation that occurs between entry and exit of roll 1 is measured by comparing the difference in the number of pulses per unit time from a transmitter 19/24 on the roll (equivalent to entry speed) and a second transmitter 20/25 on the material at exit (exit speed). This difference is compared by unspecified means with a desired value and the result used to adjust the speed of an electric motor driving roll 1 (Fig. 2, not shown). Alternatively correction may be effected by differential gear or slip coupling.

Abstract: 1402154 Fertiliser distributors AMAZONEN-WERKE H DREYER 8 Dec 1972 [8 Dec 1971] 56750/72 Heading AID An apparatus for distributing granulated or pulverulent material comprises a centrally located reservoir, lateral transversely extending booms which include discharge members and are pivotable between a raised transport position and a lower working position in which they extend transversely and intermediate stops which limit the amount the booms may be pivoted upwards by means of a lifting device for executing a turn at the end of a field. In a first construction (Fig. 2) a fan (not shown) produces an air stream in two rearwardly extending pipes 7 into which material is fed from a hopper 3 via adjustable openings and from which it is supplied to two tubular booms 8 which are rotatably mounted on the pipes 7. The booms 8 may be lifted upwards to prevent them contacting the ground when executing a turn by a device including cables 12 and pulleys 13 until they abut intermediate stops 14 which have adjustable abutment members 15. The stops 14 are pivoted into a non operative position 14' when the booms 8 are to be lifted completely into the transport position 8' in which they are retained by a hook 19 and eye 20. In a second construction (Fig. 4) material is fed from a hopper 23 via an auger 25 and distributing member 26 into delivery tubes 27 connected to shares 28 which are mounted on booms 29. The inner ends of the booms 29 have lifting arms 40 which are connected via lost motion linkages to an hydraulic cylinder 35 and in the lowered position abut adjustment screws 32. The tubes 27 are held by holders 42 which are connected to an intermediate section 43 via the top part of approximately inverted G-shaped pins 44 (Fig. 6) whose lower ends 45, project rearwardly and act as stops. Abutment members 47 are adjustably mounted on the lifting arms 40 and abut against lower ends of the arms 44 when the cylinder 35 is retracted to lift the booms 29. To lift the booms 29 into the transport position, the holders 42 are detached by lifting the pins 44 so that their upper ends disengage from the intermediate section 43 and holders 42, the pins 44 are then rotated through 90‹ so that their lower ends project inwardly towards one another and the booms 29 may then be lifted upwardly either by the cylinder 35 or manually until they abut rubber buffers 48. The buffers 48 are arranged so that they are deformed when the booms are in their transport position, but, upon returning to their normal shape, they will push the booms passed their top dead centre position, after which the booms fall to the working position under their own weight.

Patent GB-621181-A (GB)
Abstract: 621,181. Automatic control systems; moisture content. PNEULEC, Ltd., and COWLAM, K. W. Dec. 20, 1946, No. 37594. [Class 38 (iv)] For controlling the moisture content of a mixture of water and sand or other finely divided material carried on a conveyer, the supply of water to the material is controlled by an electromagnetically-operated valve which is opened intermittently for periods of time governed by the resistance between spaced electrodes dipping into the material, the arrangement being such that the duration of each period of opening is inversely proportional to the moisture content of the material so that the moisture content is maintained substantially constant. In one arrangement, the valve is controlled by a relay in circuit with the electrodes and a resistance periodically varied by a constant speed motor, the time incidence of the opening and closing of the relay in the cycle being dependent on the resistance of material between the electrodes. A manually variable resistance may be provided to adjust the mean moisture content and a second relay included in the circuit to cut off the water supply when there is no material on the conveyer. In a modification, the time cycle is produced by a relaxation oscillator controlling the valves through a thermionic valve, the resistance between the electrodes being employed to vary the biassing conditions within the time cycle. In a further modification, the water valve is actuated by a relay switch, the opening and closing of which is controlled by the charging and discharging of a condenser in circuit with the electrodes dipping into the material. The valve is maintained open during charge for a time dependent on the moisture content, after which the condenser is discharged through an auxiliary resistance, the value of which is preset manually. A relay in circuit with the auxiliary resistance is released at the end of discharge to close the charging circuit through the electrodes and thus restart the cycle. Ina further arrangement, the valve may be operated in such a way that the amount of opening is proportional to the duration of the operating current in the time cycle.

Abstract: 721,195. Calculating-apparatus. OLYMPIA WERKE WEST GES., [formerly ORBIS BUROMASCHINENWERKE GES]. Nov. 8, 1950 [Nov. 8, 1949], No. 27356/50. Class 106 (1). The control keys of a calculating machine are looked by the motor switch member at the end of their downward stroke, the switch member, and an auxiliary member pivoted thereto, then moving inwardly to embrace a projection on the operative control key stem and switch on the motor. Overlapping stems of a set of control keys 1a-1d have their edges shaped as shown in Fig. 2 for coaction with a pivoted yoke 16 connected with the motor switch and an auxiliary yoke 17 pivoted upon the yoke 16. Normally, abutments 9 on the key stems engage the auxiliary yoke 17 to hold the yoke 16 in the switch-open position against the action of a spring 19 which also maintains the auxiliary yoke in an upper position defined by a slot 15 in the yoke 16. When one of the keys is depressed, and after it has exercised its control through linkage 12, 13, a projection 7 on it depresses the auxiliary yoke 17 clear of the abutments 9 of the undepressed keys. A notch 8 in the depressed key then being opposite the auxiliary yoke 17, the yoke 16 is released to the spring 19 and closes the motor switch. The depressed key is retained during the ensuing machine cycle by engagement of the yokes 16 and 17 over the projection 7 and in the notch 8, and the remaining keys are held against depression by engagement of the auxiliary yoke 17 under their abutments 9. A crowding lock 10 prevents simultaneous depression of two keys.

Title: Data transfer system
IPC: G06F11/14
Filed: 1978-10-24
Abstract: In a large data handling system in which binary data is transferred parallel wise between units, it is necessary to check the accuracy of such transfer. If any error occurs it is desirable to be able to isolate the bit place at which the error has occurred. To do this, when a multi-bit data block is received, the receiver 2 sends an invert signal to the transmitter 1, which causes the block to be sent a second time, but this time inverted. The two versions of the block as received are compared and as long as each bit of the original differs from the corresponding bit of the inverse version, the block is accepted as valid. If two bits being compared are found to be identical a fault indication is given, and the comparator also indicates which bit place is at fault. <IMAGE>
