Filed: 1952-07-28
Abstract: 708,221. Photo circuits of photo-electric cells. GENERAL ELECTRIC CO. July 28, 1952 [Sept. 12, 1951], No. 19053/52. Class 40 (3) In an arrangement for effecting a control or indication in response to a change in light intensity a photo-cell of the type having a low resistance in one direction and a resistance variable with incident light in the other is arranged to shunt current from a device which responds to a change of current through it. As shown an electromagnetic relay 5 is fed from an alternating current source through a resistance 3 and rectifier 4. A photo-electric cell 8 of the type described above shunts the relay coil. This cell may be a germanium disc with a side contact, a point contact on one surface and receiving light on its other surface. Normally relay 5 holds its contacts open. Light incident on the photo-cell reduces its resistance causing an increased voltage drop in resistor 3 and relay 5 drops out. In the embodiment of Fig. 2 (not shown) the relay is replaced by a galvanometer. The Specification states that the photo-electric cell has the effect of smoothing the half-wave A.C. supply although a direct voltage supply may be used.

Title: Durable open mesh fabric and process of making same
IPC: D03J1/00
Filed: 1954-06-30
Abstract: In weaving an open-mesh fabric, the warp and filling yarns of the fabric are caused to adhere at their points of intersection to prevent yarn slip while leaving the mesh openings substantially unobstructed and the warp yarns still under loom tension.  The fabric may be woven from yarns coated with thermoplastic adhesive and heated while on the loom, to cause adherence at intersections, or a woven fabric, while on the loom, may have the yarns impregnated and coated with adhesive, which is hardened to cause adherence.  Suitable adhesives are synthetic rubber latices, e.g. neoprene or butadiene-acrylonitrile copolymer, natural rubber latex, solutions or emulsions of polyvinyl butyrate, melamine resins, polyvinyl acetate, or ethyl cellulose, liquid phenolic resins, or solutions of casein, starch, natural gums or glue.  The fabric may be plain, twill, gauze or leno weave and of rayon, nylon, glass, cotton, linen, wool or asbestos, with single or multiple filament yarns.  After impregnating, the fabric may be passed over an orifice which breaks films of adhesive closing the fabric meshes by blowing air, which may be heated, or steam therethrough.  The fabric then passes under radiant heaters which harden the adhesive.  The adhesive may, alternatively, be applied by spray, and may be hardened by hot air blowers or sprays of precipitant or hardening agent.

IPC: G01V1/24
Filed: 1964-05-15
Abstract: 1,064,038. Seismic exploration. TEXAS INSTRUMENTS Inc. May 15, 1964, No. 20399/64. Heading H4D. Seismic signals derived during exploration are converted, by field equipment, into signals of digital form and transmitted, e.g. by radio transmission to a remote data processing point. At the field station the digital signals, which are recorded on magnetic tape, are also converted back to analogue form and photographically recorded together with the direct seismic traces for monitoring purposes. Fig. 1 shows the general arrangement comprising a spread of geophones 4 the outputs of which, due to the reflection of seismic waves from layers 132, 133, are fed over separate channels and pre-amplifiers 115 to a multiplexer 116 which samples the amplitude of the input signals and supplies the samples to an analoguedigital-analogue-converter 117. The latter converts each sample into a 12-digit binary number (Fig. 3, not shown) which in addition to being recorded on magnetic tape 122 together with digital clock signals referenced to zero at the moment of firing shot 131 are supplied to a radio transmitter 118 for transmission to a remote data processing centre utilizing, interalia, a special purpose digital computer 121. When a field record has been made the tape in 122 is played-back and the output signals fed to converter 117 which, together with multi-plexer 116 (detailed in Figs. 2 and 2a, not shown) also operate to reconvert the input digital signals to analogue form. The latter signals are then supplied to the pre-amplifiers 115 and the output signals recorded as conventional seismic traces together with the directly desired seismic traces by means of a camera 104 to enable the system to be monitored. By transmitting the seismic information to the data processing centre in digital form loss of information such as encountered in the transmission of analogue signals is avoided. Circuit details of the elements included in the blocks of Figs. 1, 2 and 2a are given.

Title: Improvements in electrical indicators for railways and the like
IPC: B60T7/18
Filed: 1919-08-21
Abstract: 157,498. Gardner, J. Aug. 21, 1919. Order-type apparatus. -A three-position indicator which may be used as a relay consists of two electromagnets a, a<1> joined by a yoke d, and a spindle e which forms part of the magnetic circuit and carries an armature c which remains in the position to which it was last moved until the influencing magnet is wholly or partly deenergized. Each magnet has included in its circuit a source of current h and one or more contacts g, g<1> of the kind described in Specification 3405/14, [Class 38 (v), Electric switches &c.], fixed adjacent the track rails and adapted to interrupt or diminish the current when influenced by the vibration set up by a passing vehicle. When the armature is in the neutral position, each magnet normally exerts an equal and opposite pull upon it, so that under the influence of gravity it remains in that position until a vehicle entering a section operates the contact g; the pull of the electromagnet a upon the armature is thereby reduced and the unaffected magnet a<1> pulls the armature, which is held in this operated position after the train has cleared the contact g and the magnet a is restored to normal strength. When the vehicle passes the contact g' at the exit end of the section, the magnet a<1> is similarly de-energized, the armature is drawn over by magnet a, and retained until the following vehicle or train enters the section. A pointer or other indicating means may be fixed to the armature. In the event of failure of the supply of current, the armature assumes the neutral position. Stops may be provided to limit the movement of the armature, which may be biassed and polarized, and the coils may be of the type commonly employed in galvanometers, with the armature moving within them. In a modified form, the armature is pivoted at the midpoint of its length, with an electromagnet of horseshoe form acting upon each end, arranged with windings upon the limbs nearest the extremities only, the other limbs terminating near the pivot.

Title: Device and method for producing code members
IPC: G06K1/18
Filed: 1965-05-14
Abstract: 1,103,477. Making coded discs. D. H. BALDWIN CO. 14 May, 1965 [22 May, 1964], No. 20535/65. Heading G4H. Digital values stored on, for example, a tape 26 (Fig. 1) are converted to analogue electrical signals in a digital to analogue converter 32 which are then sent to a code generator 33. The generator emits pulses spaced apart a distance corresponding to the value of the digital numbers stored on the tape so that a recorder 24 is actuated to mark a rotating member e.g. disc 22 at points a distance from a reference point on the disc proportional to the magnitude of the analogue signal. In the form shown, each digit on the tape is represented in binary form by four markings 220 (Fig. 2) occurring before clock markings 46 representing the four most significant digits and three markings occurring with the clock pulses, the fourth marking 218 controlling a flip-flop which determines whether the marking on the disc is on an opaque section or a transparent section. Further markings 72, 72A indicate whether the recorder 24 should be moved radially inwards or outwards. Magnetic sensing heads 30A, 30B, 30C, 30D, 30E, 30F sense the markings and send corresponding signals to the digital to analogue converter 32 where the signals corresponding to the markings 220 are delayed so that all the signals are emitted simultaneously to the code generator 33. The output from the code generator is in the form of a substantially constant voltage with sudden drops in voltage at distances apart representing the analogue signals. This output is used to control a recorder 24. To prevent errors, markings on a disc 272 rotating with the coded disc 22 are sensed by photo-electric means 276 and the signals from this compared with the clock pulses from the markings 46 on the tape 26, the result of this comparison being used to control the motor 270 rotating the turntable 20 on which the coded disc is placed.
