Title: Improvements in or relating to electronic control devices
IPC: H01J29/70
Filed: 1953-09-16
Abstract: 743,236. Automatic control systems. TURCK J. Sopt. 16, 1953 [Sept. 17, 1952], No. 25562/53. Class 38 (4). [Also in Groups XXXVIII, XL (a) and XL (b)] An electronic self-guiding device comprises photo-electronic means for converting an optical image of a target into an electronic image which is projected on to a collective target divided into several adjoining elements these elements being connected to deflectors which maintain the beam centred on the target and the energy applied to the deflectors being a measure of the angular deviation of the object. As shown, the target A is imaged by means of lenses 3 to a semi-transparent photo-cathode 2 which emits electrons accelerated by electrodes 7 and focused by electrodes 5, 6 on to a target 4 divided into four sections (Fig. 3). Each section of the target is connected through amplifiers 9 with a corresponding deflector plate 8, the arrangements being such that opposite plates receive equal and opposite potentials. The potentials centralize the image on the target and the potential applied to each pair of plates is measured by a meter 10 and differentiated at 11 to indicate rate of angular deviation of the target on a meter 12. Both outputs may be applied to a servo system for example an automatic stabilizer or automatic pilot for an aircraft or guided missile. The individual accelerating electrodes may be replaced by a single electrode of resistive material so that a potential gradient is produced along it. In an alternative arrangement (Fig. 5, not shown), the image is received on an opaque cathode from the front of the cathode by light directed in through the side of the tube. In the arrangement of Fig. 6, light is focused on to a photo-conductive target 22 by a lens 36, this cathode also receiving an electron beam from a source 23. The electrons are reflected from the cathode to the target 4 to a degree dependent on the light incident on the cathode.

Title: Method of producing xerographic plates
IPC: G03G5/085
Filed: 1963-04-02
Abstract: 1,049,872. Electrophotographic materials. RANK-XEROX Ltd. April 2, 1966 [April 2, 1962], No. 25919/66. Divided out of 1,049,871. Heading H1K. A method of producing a xerographic plate comprises forming upon a conductive support a layer comprising a mixture of finely divided inorganic photo-conductive particles and finely divided glass particles and heating the layer to the fusing temperature of the glass particles to fuse the layer to the support. The photo-conductive particles form up to 60 weight per cent of the fused layer. Oxide glasses are suitable but low-melting glass-forming sulphides such as arsenic sulphide and antimony sulphide are possible variants. Suitable support materials include aluminium, brass, stainless steel, copper, nickel, or zinc; and glass coated with tin oxide, with indium oxide, or with aluminium. Suitable photo-conductors are calcium-strontium sulphide, zinc sulphide, zinc oxide, zinc selenide, zinc titanate, zinc silicate, zinc-magnesium oxide, cadmium sulphide, cadmium selenide, mercuric sulphide, mercuric oxide, antimony sulphide, arsenic sulphide, arsenic selenide, gallium selenide, indium sulphide, titanium dioxide, and the lead oxides PbO and Pb 3 O 4 . Preferred materials are " phosphors " and materials containing zinc and/or cadmium and sulphur and/or selenium. Component materials for oxidic binders are discussed. The light sensitivity and dark decay characteristics of freshly prepared plates generally improve markedly during the first 24 hours after manufacture. Some plates with good electrical properties yield no picture or only pictures of poor quality but may be improved by polishing their surfaces (for example with rouge) or by soaking them in tap water for “ hour then drying them thoroughly with I.R. radiation. Distilled water and Lewis bases produce less improvement than tap water-acids are ruinous. The plates may be formed with a glossy overcoat constituted by a layer of clear glass binder or of such a material containing a quantity of photoconductor smaller than that in the main layer. A glossy surface may instead be obtained by contacting the free surface of the photo-conductive layer while it is still in a plastic or molten condition with a very smooth non-adherent surface which is removed subsequently. The xerographic properties become impaired when the surfaces of the plates are dulled by frequent use and may be restored by refiring the plates under the same conditions as when they were first made. Reference has been directed by the Comptroller to Specification 872,100.

Filed: 1973-05-31
Abstract: 1414349 Testing welding for cracks CESKE VYSOKE UCENI TECHNICKE 31 May 1973 25943/73 Heading G1S Metal is supplied at a substantially constant rate with heat whilst the source of heat and the metal test piece are relatively displaced at a variable velocity, the metal being surface fused without a filler so as to form a weld bead of varying cross-section which is then examined for cracks. In Fig. 1 a fixed test piece 3 is traversed. by a torch or electric arc 2 guided in a straight line C by a rod 4 sliding in bearings 5, 6, the rod 4 being slid to and fro by a pressure bar 8 engaging by its own pivoted weight the top surface of a conical friction wheel 7 driven by a constant speed motor 12 movable towards and away from the bar 8 by means of a rod 13 slidably displaceable by a fixed motor 16 and connecting rod gear 17, 18. As the rod 8 engages a different part of the drive cones surface so the sliding movement of the torch 2 in the direction C varies to produce a different weld on the piece 3. Figs.5-9 and 12-19 (not shown) illustrate different drives for varying the speed of the torch. The weld bead formed in this way varies over its length as regards width, depth and cross-section providing a wide range of conditions in which hot cracks may be formed for subsequent optical examination.

Filed: 1950-10-27
Abstract: Aqueous dispersions of cellulose glycollic acid or carboxymethyl hydroxyethyl cellulose, from which insoluble coatings, sizings, adhesives, films, webs, sheets and strips may be made, are obtained by acidifying an aqueous solution of a soluble salt, e.g. the sodium, potassium, lithium or ammonium salt, of the cellulose glycollic acid or carboxymethyl hydroxyethyl cellulose to form a gelatinous flock of the free ether-acid, the flock then being washed, and then dispersed, by milling, in water to form a colloidal dispersion.  Suitable acids are aqueous chloracetic, hydrochloric and sulphuric.  Preferably, the aqueous solution is extruded into an acid bath to form gelatinous rods of the free ether-acid, the rods then being washed, ground and dispersed in water.  To the dispersion fillers, humectants and plasticizers, e.g. kaolin, bentonite, fuller's earth, aldehydes such as glyoxal, salts such as aluminium chloride, glycerine, sorbitol and ethylene glycol may be added. Numerous examples are given.

Abstract: 389,821. Long-distance transmission. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Dudley, H. W. ; 123, South Oraton Parkway, East Orange, New Jersey, U.S.A.) Sept. 21, 1931, No. 26398. Convention date, Sept. 30, 1930. Drawings to Specification. '[Class 40 (iv).] To increase the ratio of speech level over cable noises in a submarine cable having high attenuation the terminating impedance is made either a pure reactance or of a value several times that of the impedance of the cable. The input to the cable is predistorted so that the upper portion of the frequency range is transmitted at the lowest transmission level permitted by interference from resistance noises, and the lowest portion of the frequency range is transmitted at the highest transmission level permitted by interference from modulation in the cable loading material. As the cable tends to attenuate the higher frequencies to a greater degree than the lower, the terminating transformer is given a low mutual inductance to give it a lower transmission efficiency for the low frequencies than for the higher frequencies. Condensers may be connected in series with the primary of the terminating transformer, either to form, with the mutual inductance of the transformer, a high pass filter primarily to keep out earth currents, or to assist in the equalization mentioned above by discriminating against low frequencies. Suitable balanced type terminating networks are indicated in the Specification for cables employing (i) earth return, (ii) twin conductors and (iii) concentric return systems. A mathematical investigation is included in the Specification which shows that for any cable a 3-decibel improvement over the matched impedance is obtained by making the terminating impedance either a substantially pure reactance or a resistance high in comparison with the cable resistance. Specifications 240,034, [Class 40 (iii), Telegraphs, Electric], and 339,685, [Class 40 (iv), Telephones &c.], are referred to.
