Title: Improvements in or relating to arrangements for loading drums of picture-telegraph machines
Inventor: HOLLAND KENNETH HERBERT
IPC: H04N1/08
Filed: 1955-08-05
Abstract: 797,841. Copying-telegraphy. MUIRHEAD & CO., Ltd. July 18, 1956 [Aug. 5, 1955], No. 22568/55. Class 40 (3). In a copying telegraph transmitter or receiver, a scanning drum for carrying the sheet to be scanned has a single narrow clamp extending along the whole length of the drum with which it is held in contact by springs, the clamps being located against axial or rotational movement with respect to the drum and having at each end levers by which either side of the clamp may be lifted from the drum surface in order to admit an end of the sheet to be secured to the drum for the scanning operation. The clamp 1 which is a narrow U-shaped bar provided with end plates 5 having long and short arms 5a, 5b is held against the drum by the springs 3 and near its ends engages pins (not shown) on the drum surface. For loading and unloading, the drum 2 removed from the transmitter or receiver, has its shaft portions 7 mounted in bearings 6a, of a frame comprising end-plates 6 provided with pins 9 on which are mounted bell-cranks 8 with arms carrying a roller 10 and pins which move in slots 6b and carry a second roller 11. For the loading operation, the bell-crank is rocked to the position opposite that shown and the drum rotated clockwise until the short arms 5b engage cam projections 8a and raise the clamp on one edge so that the leading edge of the sheet can be inserted. The drum is then moved slightly anticlockwise to disengage the arms 5b from the projections 8a and the bell-crank 8 is rocked to the position shown so that the roller 11 is against the sheet on the drum and the projections 8a are out of the path of the projections on the short arms 5b. The drum is then rotated clockwise with the roller 11 engaging the sheet until the long arms 5a engage the fixed cam members 6c so that the other longitudinal edge of the clamp 1 is raised to permit the insertion of the trailing edge of the sheet. Further rotation of the drum allows the arm 5a to pass clear of the cam member 6c and the clamp to fall back so that both edges of the sheet are gripped. The drum surface may include stops to locate the leading edge of the sheet. The sheet can be unloaded by manually rocking either plate 5 in opposite directions, or with the drum placed in the loading device and with the bell-crank 8 in the position opposite to that shown, clockwise rotation of the drum operates the long arms 5a to engage projections 6c to release the trailing edge and the projections 8a operate the short arms 5b to free the leading edge of the sheet which can then be withdrawn.

Title: Improvements relating to the preparation of chlorophenylchlorosilanes
IPC: D06M13/517
Filed: 1955-08-05
Abstract: Polysiloxane oils containing silicon-bonded chlorophenyl groups which contain an average of at least 3 chlorine atoms per phenyl group, are used singly or in admixture as lubricants, especially when modified by the addition of soaps, e.g. lithium 2-ethyl-hexoate (to make greases), antioxidants and inhibitors.ALSO:Chlorophenylchlorosilanes containing an average of at least 3 pheny-bonded chlorine atoms per phenyl group are obtained by passing chlorine into a solution in carbon tetrachloride of a silane of the formula (C6H5)nSiCl4-n, where n is 1 or 2, in the presence of anhydrous aluminium trichloride, there being present at least 0.75 part by weight of carbon tetrachloride per part of silane.  The amount of catalyst is generally from 0.01 to 5 per cent of the weight of silane. Temperatures of about 50 DEG  to 100 DEG  C., preferably refluxing, are employed and anhydrous conditions are maintained.  The reaction mixture is then fractionally distilled to separate the chlorophenylchlorosilanes.  To avoid silicon-phenyl cleavage during this step, sodium chloride is added to the mixture in amount equal to the amount of aluminium chloride originally employed, forming a complex therewith.  The examples describe the preparation of mixtures of di-, tri- and tetrachlorophenyltrichlorosilanes, including the compound 2,4,5,6-tetrachlorophenyl trichlorosilane, and of chlorophenyl dichlorosilanes.  Polysiloxane oils are prepared by hydrolysing the chlorophenyl chlorosilanes containing an average of at least 3 phenyl-bonded chlorine atoms per phenyl group.  Examples describe the cohydrolysis of (a) trichlorophenyl trichlorosilane, dimethyldichlorosilane and trimethylchlorosilane; and (b) tetrachlorophenyltrichlorosilane, dimethyldichlorosilane and trimethylchlorosilane.  The fluids may be modified by the addition of soaps, e.g. lithium-2-ethyl-hexoate (to make greases), antioxidants and inhibitors.

Abstract: 1,190,815. Cathode-ray tube circuits &c. GENERAL ELECTRIC CO. 16 May, 1967 [23 Aug., 1966], No. 22642/67. Heading H4T. [Also in Division H1] A deflection system for a plural beam (e.g. in line three gun and red, green, blue) cathoderay tube comprises a deflection yoke 23 with vertical windings (89, 91) (Fig. 5, not shown) and horizontal windings (53, 55) (Fig. 4, not shown) on a truncated ferrite core (47) for example, to provide the main vertical and horizontal deflecting fields, the vertical and horizontal windings further including turns (93, 95, 97, 99 and 57, 59, 61, 63) to provide flux components perpendicular to the main vertical and horizontal fields respectively so that each beam produces a raster substantially parallel at all points to that produced by the other beams. The rasters may differ in size (Fig. 9, not shown). The horizontal size difference results from the correction forces overcoming parabolic errors and the vertical size differences mainly from gun misalignment. Vertical and horizontal static convergence and size correction assemblies 25, 27 may be energized by the sawtooth deflection currents applied directly to the size correction windings (184, 192 and 211, 213, 221 and 223 respectively) (Figs. 10 and 11, not shown), cylindrical ferrite magnets (183, 191 and 209, 219), diagonally polarized, being rotated to control the magnitude and polarity of the steady state field. Also the proximity of the C-shaped core members (179, 187 and 205, 215) to the internal polepieces (171, 173, 175, 177 and 201, 203) can be varied to control the field magnitude. Fourier series are disclosed corresponding to specific deflection yoke winding distributions. The deflection circuitry (Fig. 12) includes vertical output stage 33 with driver tube 233, vertical linearity control 243, output transformer 241 connected to first and second windings, 124 and 128, which are connected to size correction windings 184, 192 (also Fig. 10, not shown). The horizontal output stage 39 with driver tube 245 comprises a damping circuit including damping diode 261 to develop the sawtooth deflection circuit across the autotransformer. H.V. rectifier 269 is connected to a tertiary portion of the transformer to provide the C.R.T. high voltage. Secondary 271 is connected to deflection yoke windings 132, 136 and horizontal size correction windings 211, 213, 223 and 221.
