Abstract: 1,157,769. Image scanning apparatus. C.I.T. COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 26 March, 1968 [4 April, 1967; 22 Aug., 1967], No. 14582/68. Heading H4F. A document 10, Fig. 2, is illuminated by light sources 21, 22 and an objective 12 co-operating with a mirror 13 provides a spherical image on a screen 14 formed by the inner face of a rotatable disc 30. The rotary member 30 carries eight optical fibres 41 to 48, Fig. 4, the outer ends of the fibres terminating in projections 341 &c. some of which may be blanked off as at 38, Fig. 2, if required. Adjustable screens 61, 63 define the scanning zone. The inner ends of the fibres co-operate with a mirror 28 to reflect light on to a photosensitive member 35 which is connected to an amplifier (not shown). In operation, the image on the screen 14 is scanned by the outer end of a fibre, e.g. 41, as the disc 30 is rotated and when the next fibre 42 enters the scanning zone the document is advanced along the arrow 15. The rotation of the disc 30 and the movement of the document may be produced by a single motor 23. The receiver, Fig. 7 (not shown), operates in an inverse manner.

Title: Polymeric lubricating oil additives
Inventor: FORD JOHN FREDERICK
IPC: C08G79/06
Filed: 1964-04-09
Abstract: Liquid phosphoramidates of olefine polymers are used as mineral or synthetic lubricating oil additives.  The phosphoramidates are prepared by reacting an olefine with a phosphorus halide the molar ratio of olefine to phosphorus halide being 100:0.1-25, in the presence of at least 1.5 moles of Friedel-Crafts catalyst per mole of phosphorus halide and at a temperature below 60 DEG  C. so as to produce a phospho-halogenated polymer, removing the catalyst from the phospho-halogenated polymer and reacting the latter with an amine, preferably a linear polyamine, to produce a phosphor-amidate of the polymer.  The preferred amines are tetraethylene pentamine, triethylenetetramine and diethylene triamine.ALSO:A liquid phosphorus- and nitrogen-containing polymer is obtained by reacting an olefine with a phosphorus halide, the molar ratio of olefine to phosphorus halide being 100:0.1-25, in the presence of at least 1.5 moles of a Friedel-Crafts catalyst per mole of phosphorus halide and at a temperature below 60 DEG  C. so as to produce a phospho-halogenated polymer, removing the catalyst from the phospho-halogenated polymer and reacting the latter with an amine, preferably at a temperature of 50 DEG  to 100 DEG  C., so as to produce a phosphoramidate of the polymer.  The preferred catalyst is AlCl3 mixed with TiCl4 and the preferred amines are linear polyamines such as tetraethylenepentamine, triethylenetetramine and diethylenetriamine. The catalyst residues may be removed by washing, but if this causes hydrolysis the polymer should be rehalogenated before treatment with the amine.  In the rehalogenation a chlorinating agent such as a sulphur halide or oxyhalide or a phosphorus halide or oxyhalide may be used.  Both the phosphorylation/polymerization reaction and the rehalogenation are preferably carried out in an inert solvent. In the example, the monomer polymerized is 4-methylpentene-1.

As shown, Fig. 1, the intensity pattern 1a is produced as a hologram by means of the interference of two partial beams of a sound-modulated light beam issuing from a coherent light source 3. Alternatively, Fig. 2, a diffraction grating 12 is imaged on the record medium 9 by the sound-modulated light beam. A pulse frequency may be superimposed on the sound signals, the light source possibly being a pulsed laser. In playback, Fig. 4, (not shown), a sound signal is derived from the intensity of light diffracted through a given angle by the record. Several sound tracks having different grating constants may be mutually superimposed, Figs. 5 and 6, (not shown).

Abstract: 832,889. Bending glass sheets. PITTSBURGH PLATE GLASS CO. May 9, 1958 [May 29, 1957], No. 14883/58. Class 56. At its outboard end each pivoted wing section 32 of a sectionalised bending mould for glass sheets, particularly for vehicle panoramic windscreens, is provided with a flat extension plate 70 having an upper surface 72 substantially parallel to and below the tangent to the plane of the shaping surface at that end. The extent of the plate is such that, in the open position of the mould, the lower face of the lower, G<SP>2</SP>, of a pair of sheets G<SP>1</SP>, G<SP>2</SP> to be bent rests on the surface 72 and not on the edge 42 of the wing section, intermediate portions of the lower face of the sheet G<SP>2</SP> being supported on the outboard ends of the centre section of the open mould. As the wings rise during the closing of the mould the face of the plate G<SP>2</SP> contacts the edge 42 but the tips of the sheets are still beyond the tip of the edge 42. This arrangement permits the glass tips to develop compressive stress during annealing and avoids the defects shown in dotted and dashed lines in Fig. 4. Indicia such as lines of holes may be provided in the surface 72 for the ends of the flat glass sheets to register with during loading of the mould.

Abstract: 629,595. Moulding shaped articles from magnesite flooring material. GOETZL, H. M. May 17, 1946, No. 15073. [Class 87 (ii)] [Also in Group XXIII] Articles such as lengths of cove-skirting for floors are produced from magnesite material (calcined magnesite, magnesium chloride and a filler) by first moulding the article approximately to shape between upper and lower mould members, the former being adapted to slide on the latter to act as a strickle or templet, and, after hardening, cutting to final shape by means of a rotary cutter having a plurality of radial, shaped, blades, (see Group XXIII]. The lower mould Fig. 5 (shown on edge) comprises a base 2 with side members 1, 3, the latter or both being hinged to the base. A zinc sheet 6 covers the base and tinned sheet iron inserts 4, 5 cover the top and inside faces of the sides 2,3. The top mould (Fig. 7, also on edge) is profiled at 7 and covered with a zinc sheet 10. Side plates 8, 9 are provided to engage outside the members 1, 3 of the lower mould. The lower mould is filled with the plastic material and shaped by working the top mould back and forth, the moulding being thicker than required by the thickness of the inserts 4, 5. After the initial or final hardening, this excess is removed by a rotary cutter having blades shaped e.g as in Fig. 1. The base of the lower mould may be ridged to provide keying grooves in the product, the end faces of which may be bevelled so that when laid on inset concrete a retaining wedge of concrete is formed between adjacent lengths of skirting.
