IPC: H03K3/26
Filed: 1965-08-19
Abstract: 1,100,620. Transistor switching circuits. CREED & CO. Ltd. 20 Aug., 1965 [22 Aug., 1964], No. 35917/65. Heading H3T. In an electric pulse relay circuit when the amplitude of the input a exceeds a predetermined level stage 1 is caused to oscillate and when the amplitude of these output oscillations b reach a given value a monostable stage 2, which produces a pulse at c of longer duration than the period of the oscillator, is triggered to control a keying stage 3 arranged to supply D.C. to a load, such as a transistor T3 controlling the connection between telegraph wires 12, 13 for producing a pulse output at d. For an input telegraph signal a (Fig. 3, not shown), as long as the oscillations at b remain above the triggering value for the monostable circuit, pulses at c will continue to be produced until the end of the input signal. The input voltage at which T1 starts oscillating may be varied by resistor R2. A voltage dependent resistor R1 protects the oscillator 1 from overloading and diodes D1, D3 provide bias for transistors T2, T3. In a modified circuit (Fig. 2, not shown) an input signal a causes T1 to oscillate and trigger the monostable stage 2 which then starts to produce an output pulse c. The windings of a common coupling transformer are arranged so that the oscillations of the oscillator 1 are stopped until the end of the output pulse c at (t 4 , Fig. 3, not shown), when oscillations may start again to repeat the above operation. By suitable arrangement of the transformer windings the monostable circuit may either be triggered on the leading or trailing edge of the oscillator pulses. Two relay circuits may be arranged having their input connected in parallel (Fig. 4, not shown), so that input signals of opposite polarity operate one or the other circuit to switch a different pair of telegraph lines for double current working.
Patent NL-6515084-A (NL)
IPC: H05H5/00
Filed: 1965-11-19
Abstract: 1,116,442. Particle accelerators. UNITED KINGDOM ATOMIC ENERGY AUTHORITY 16 Nov., 1965 [19 Nov., 1965], No. 47260/64. Heading H1D. In a D.C. particle accelerator at least one " quartet" of axially localized transverse magnetic fields is provided along the acceleration tube to deflect the beam successively away from the axis of the tube, parallel to the axis, towards the axis and then along the axis again or, in practice, along a path parallel to, but slightly displaced from the axis, as shown. Spurious electrons are, however, deflected into the electrodes and the electron loading is thus reduced. The magnetic fields may be set up by one or more pairs of permanent magnets or by annular permanent magnets incorporated in selected electrodes, i.e. mounted in the dished portions of selected electrodes with coverplates provided to shield the magnets from the electric fields. At the input end of the acceleration tube electrodes with circumferentially corrugated apertures may be used to provide non-axial electric fields. Alternatively electrodes with non-corrugated circular apertures progressively decreasing in diameter may be used. In an arrangement with pairs of permanent magnets the apertures of the electrodes have enlarged end portions to aid evacuation and successive electrodes are rotated, in certain regions where the magnetic fields are closely spaced by 90 degrees, to provide optical baffling. In a second arrangement with annular magnets Fig. 7 (not shown), relatively large apertures are used to increase pumping speed. Electrodes dished in either direction relative to the beam may be used. In the arrangement shown, certain of the electrodes may be flat with a transitional degree of dishing of the electrodes on either side in order to avoid any reduction in the number of electrodes along the acceleration tube due to the incorporation of the magnets. A progressive dishing of the electrodes adjacent those carrying the magnets may also be used in the second arrangement, Fig. 7 (not shown). In the arrangement shown, successive " quartets " divert the beam to opposite sides of the tube axis. In the second arrangement, Fig. 7 (not shown), the beam is always diverted to the same side. The accelerator may be for accelerating ions or electrons.

Title: Metal and semi-conductor purification - and mfg. monocrystals by means of zone melting
IPC: C30B13/16
Filed: 1968-08-14
Abstract: Direct current is conducted through the rod-shaped material to be melted. Inner crystal is used, whereby the crystallographic orientation is directed in the direction of the rod which has the greatest Peltier coefficient. Advantage over prior art for the production of monocrystals, whereby the anisotropy of the Peltier effect is meant to be used, in that direct current is conduted through the zone to be melted and the liquid zone is made to move a number of times through the rod. The retarding factor here is the monocrystal formation beforehand, the anisotropic effect being effective only in the tractive direction of the crystal. The crystal areas occurring spontaneously are, consequently, for the most part only determined by the anisotropy in the direction of growth with regard to their orientation.

Title: Determination of coverage by infra-red tracking instrument - with measurement of visual range and water content of air
IPC: F41G3/08
Filed: 1974-10-24
Abstract: The optical visual range and the water content of the air are measured and these results, together with the assumed target data and sensitivity of the infra-red instrument, are used by an electronic computer to determine the coverage of the infra-red instrument. To determine the absolute water content of the air the relative water content and the air temperature are measured. An electrical resistance dependent on humidity can be used to determine the water content of the air. The coverage of the infra-red instrument is determined by atmospheric absorption and atmospheric dispersion.

Title: Drag control for fixed pitch marine blade - with welded seams in pattern on front and back of blade
IPC: B63H3/12
Filed: 1975-11-06
Abstract: The front (4) and back side (5) of the marine screw blade are warmed by localised heating and have a pattern of weld seams applied, proud of the surface. This alters the inclination of the tip of the blade (3) to tune the blade drag to the optimum engine speed. Weld seams on the back (5) tend to flatten the pitch, while seams at the front increase the pitch. the weld seams are smoothed off by simple machining to allow the blade to be used effectively. The process alters the blade pitch to suit the hull drag as the ship ages.

Filed: 1982-04-20
Abstract: The invention relates to a DC/AC converter provided with two transistors (11 and 20), the current through an inductively stabilized discharge lamp (16, 15) to be connected to the converter alternately flowing through one and the other transistor. 
<??>According to the invention, the lamp (15) has connected in series with it a primary winding (12) of a current transformer, a secondary winding (30, 31) of this transformer being connected to a timing circuit (32 to 35: 32 min  to 35 min ) of a control device of the transistors. The timing circuit is provided with voltage-dependent elements, i.e. Zener diodes (35, 35 min ).

Title: Energy band discriminator for echo canceller - producing binary output representative of frequency distribution of input signal samples
IPC: H04B3/23
Filed: 1982-02-24
Abstract: The discriminator is intended to inhibit operation of an echo estimate generator when the far-end signal includes significant energy over only part of the band. The input (X) is applied via an amplifier/separator (201) to a precision full-wave rectifier (202), which may be followed by a mu-to-linear-law convertor for sampled digital signals. The rectified version (MAG) is divided between two filters (203,204) with different time constants determining respectively its average and modified absolute values. These are applied to a comparison circuit (205) which generates a binary control signal for a switching gate in the echo canceller circuit. If the input signal contains energy over the whole band (from about 300 to 4000 Hz for telephone speech), the control signal is at a high logic level.
