The worm meshes with a wheel 20 which rotates coarse scale decimal counter wheels 22-24 through drive pinions 26, 27 all contained within a frame 25' fixed to the slide 3. The slide also supports pinions 6, 7 in mesh with the rack 2 and connected to a gear 8 which is fixed to a shaft 8A and to a gear 9 which is rotatable on a shaft 9A. A pre-loaded flat coil spring 10 is fixed at its ends to shaft 9A and gear 9 so that constant torque is applied to them preventing backlash, and a pinion 12 meshing with gears 8 and 9 is fixed to a shaft 11A mounting a fine scale reading graduated disc 11. In operation, the numbers on the disc 11 align with the numbers on the counter wheels 22-24 to show as a line of numbers readable through a window 13.

Title: Bistable trigger circuit
IPC: H03K3/286
Filed: 1959-11-06
Abstract: 890,851. Bi-stable circuits using transistors or valves. STANDARD TELEPHONES & CABLES Ltd. Nov. 6, 1959 [Nov. 7, 1958], No. 37709/59. Class 40(6). In a bi-stable circuit of the type comprising two alternatively conducting active electronic elements, one of two windings oppositely wound on a square loop core is included in the circuit of each element so that when the supply voltage is removed from the circuit the information stored in the bi-stable circuit remains stored in the core and when the supply is replaced the bi-stable circuit is restored its previous condition. Fig. 1 shows a transistor bi-stable circuit in which each collector circuit includes one of the two reversely wound windings W1, W2 of a square loop core K. When transistor Tl is conducting the current through winding W1 saturates the core in one direction. Accordingly, if the supply is interrupted and then restored, current will quickly build up through winding W1, since for currents in this direction the winding has no incremental inductance. Current will only slowly build up in winding W2 since winding direction is such as to tend to set the core to its other state of saturation and accordingly the winding has a large incremental inductance. The transistor T1 will thus again become the conducting transistor. Similarly if transistor T2 is non-conducting before the interruption it will restore to conduction after the interruption. In an alternative circuit (Fig. 2 not shown) further windings on the core K are connected in series with the base input circuit of the transistors so as to hold the previously non-conducting transistor in this state when the supply is restored. The transistors may be replaced by valves.

Title: Converters and circuitry therefor
IPC: H02M1/40
Filed: 1973-08-14
Abstract: 1421797 Automatic voltage control WESTERN ELECTRIC CO Inc 14 Aug 1973 [17 Aug 1972] 38469/73 Heading G3R [Also in Division H2] In or for a D.C.-D.C. converter, a circuit for balancing the currents in two switching devices 10, 20 so as to avoid saturation of the main transformer 30, comprises means 15, 16 for monitoring the currents in the respective switching devices 10, 20 and for providing a signal representative of the difference between said currents and means responsive to said difference signal for modifying the drive signals to the switching devices 10, 20 so as to equalize conduction in said devices. As described, transistors 10, 20 are driven into conduction alternately so as to connect a D.C. supply 1, 2 to alternate sides of the primary winding 31 of transformer 30. If the characteristics such as saturation voltage level, charge storage or delay times of the transistors are not matched, the transformer 30 could be driven into saturation. Signals representing the respective currents are developed across resistors 15, 16 and fed to terminals 101,102, Fig. 3, of a differential amplifier comprising transistors 110, 120, 210, 220 which provide an output across capacitor 207 indicative of the difference current. This output is added to a squarewave from multivibrator 300 and used to control the D.C. level of a triangular wave, Fig. 2, generated by integration at 202. The triangular wave is fed to the bases of transistors 410, 420 and compared with voltages at the bases of transistors 430, 440 which respectively represent the upper and lower thresholds 26, 27. Drive pulses for one of the transistors 10, 20 are derived from the collector of transistor 410 via transistor 450 during the time the triangular wave exceeds the upper threshold 26. Further pulses for the other main transistor 10, 20 are derived from the collector of transistor 420 via transistors 460, 470 when the triangular wave is below the level of the lower threshold 27. The position of the triangular wave relative to the two thresholds 26, 27 is automatically adjusted in response to the signal at the base of transistor 210 so as to equalize the currents in the main transistors 10, 20. Automatic Voltage Control. The D.C. output voltage is compared at 60 Fig. 1 with a reference (not shown) and the resulting error fed to the base of transistor 480 which controls the separation of the two thresholds 26, 27 and thus maintains the D.C. output voltage from the converter constant.

Guides determined by the formula may be used to couple laser light to fibres even though the active zone of the laser cannot be brought into the same plane as the guide. The guide can be in the form of a discrete thin film applied by evaporation or cathode spluttering and may have a thickness of one wavelength, two or more guides being combined on the same substrate. The guide may form the resonator of a laser or be used as a beam divider or as an image switch or as an optical isolator. The guide may also divide an input image into output images of non-uniform sub-division. There is also the possibility of providing a so-called star coupler by means of an imaging system serving as a beam divider or beam coupler.

Abstract: 1,267,605. Cooling multi-disc disc brakes. MESSIER S.A. 4 Aug., 1969 [7 Aug., 1968], No. 38894/69. Heading F2E. In Fig. 2 air is drawn centripetally from the atmosphere between rotor discs 15 and stator discs 16 through suction passages 18 into an annular chamber 24 and thence through further suction passages 20 into an annular manifold 25 and thence by way of a conduit 29 into a suction device 31 mounted on a support 10 for a stub axle 12 and driven preferably by an electric motor 32. The air is discharged through an exhaust duct 33 preferably in a radial direction relative to the stub axle 12 on which the wheel 13 is mounted, but alternatively in a direction F2 parallel to the axle. Preferably, the suction device 31 is of the centrifugal type but it may be of the axial type. The fluid-tightness of manifold 25 is ensured by rubber joints 26, 27, between itself and the end wall 21. As shown, wall 21 is secured to support 10 on the vehicle, which is preferably an aircraft. In a modification (Fig. 4, not shown), the wall 21 is not thus secured, but is instead integral with a torque recovery arm. Because of the rubber joints 26, 27, the brake structure including the wall may pivot slightly relative to support 10 and stub-axle 12. In Fig. 5 a common conduit 29 and suction device 31 serve the brake structures of two wheels 113, 213. The cooling means may operate with the brakes on, but in that case the cooling is more effective when the friction pads are mounted on individual segments or shoes.

Title: Improvements in or relating to processes and apparatus for surface-hardening hardenable steels
IPC: C22B4/00
Filed: 1965-09-14
Abstract: A steel workpiece is surface hardened by heating it rapidly to form an austenitic layer metastable at room temperature using a plasma torch having no constricting aperture for the plasma (see Fig., not shown), and transforming the layer by applying further energy, preferably also effected with the aid of the plasma torch, into a fine-grained martensitic structure.  The torch is provided with an additional charge carrier source to prevent deionizing the plasma. The cross-section and intensity of the plasma beam are controlled by varying the current intensity of the arc, and the quantity and type of gas conveyed so that the plasma beam can conform to the surface to be hardened.  For continuous surface treatments, e.g. of cutting edges of tools or slideways, the shape of the plasma beam and rate at which energy is supplied through the beam are varied during treatment to conform changing configuration of the surface to be hardened.  The torch may be operated with D.C. or A.C.  Prior processes are disclosed wherein surface heating is effected by electron or laser beams.
