Title: Method of recording by irradiating and coating dielectric material
IPC: H04N5/80
Filed: 1954-05-14
Abstract: 754,581. Copying-telegraph and television receivers. WESTERN ELECTRIC CO., Inc. May 14, 1954 [May 15, 1953], No. 14195/54. Class 40 (3). [Also in Group XIX] A method of recording information by irradiating and coating a solid dielectric material comprises the steps of subjecting the material to radiation which is varied in dependence on the information to be recorded and applying one or more surface layers of solid coating material by vapour deposition on to the irradiated dielectric material, the layer or layers of coating material serving to reveal the recorded matter by the extent to which the coating material is deposited on the dielectric material. In the apparatus shown, the dielectric material is a thin strip 19 of cellulose acetate or nitrate subjected to an electron beam varied in accordance with signals applied to the control grid 30 of a gun 18 and moved in front of a back plate 20. The strip is then coated with a layer of silver from a molybdenum filament 23 loaded with silver and is subsequently coated with a layer of zinc vaporized from a coil-heated crucible 27. The silver deposit may be such that the record is not visible, or may be materially increased to provide a visible record. Copper and cadmium may be employed instead of silver and zinc respectively. The dielectric sheet may be of cellulose acetate, butyrate, polystyrene, polyethylene, terephthalate, ethyl cellulose or regenerated cellulose and may be constituted by a dielectric backing medium such as a paper support, coated with a dielectric lacquer. The dielectric may be stored with the record invisible after the exposure to the cathode beam or subsequent to the initial deposition of silver. The information may be recorded by ultra-violet light or an ionic beam, and in the use of an electron beam, the apparatus shown in Fig. 3 is enclosed in an evacuated casing 29. For the recording of a waveform, the signals may be applied to one pair of deflecting plates 21, and for the reproduction of an image, the strip 19 may be moved continuously and the beam 22 traversed by one pair of plates 21. Alternatively, the strip 19 may be held stationary for the reproduction of an area with the beam 22 moved in component directions by the two pairs of plates 21. The vapour deposition steps may be carried out as described in Specification 694,995, [Group XXXVI].

Abstract: Pentaerythritol and calcium or sodium formate are recovered from the mother liquor, obtained by condensing acetaldehyde and formaldehyde in the presence of sodium or calcium formate, by adding methanol to the mother liquor to precipitate the calcium or sodium formate which is separated and crystallising pentaerythritol from the residual liquor or recycling the residual liquor to a subsequent process for preparing pentaerythritol, the pentaerythritol in the recycled liquor being obtained together with that produced in the subsequent process. The mother liquor is defined as that remaining after separation of most of the pentaerythritol and polypentaerythritols.  Preferably the mother liquor is concentrated to eliminate from 50 to 8% of the water present before precipitating the sodium or calcium formate.

Title: Improvements in and relating to delaying devices for electric pulses
Inventor: CORNEY JOHN VICTOR JAMES
IPC: H03K5/13
Filed: 1960-04-26
Abstract: 923,570. Transistor pulse delaying circuits. FERGUSON RADIO CORPORATION Ltd. April 14, 1961 [April 26, 1960], No. 14660/60. Class 40 (6). In a circuit for delaying the start of an output pulse until the start of the next input pulse, a pair of capacitors are respectively charged during successive pulses, each capacitor being discharged while the other is charged and a delayed pulse of unchanged duration is generated during the discharge of each capacitor. The first input pulse at terminal T1 is passed by diode 28, differentiated at 29 and used to reverse the state of the bi-stable circuit comprising transistors 26, 27. The output from the bi-stable circuit is passed by emitter followers 12, 13 to drive diodes 18, 21 into conduction and cut off diodes 17, 22. Capacitor 15 is charged from a constant current transistor 33 via diode 18. The constant current transistor 33 is only operative during each input pulse at terminal T1, hence capacitor 15 will charge to a voltage proportional to the duration of the input pulse. Capacitor 14, charged during the previous pulse, discharges via diode 21 and the constant current transistor 37, giving a sawtooth waveform at point F. This is amplified and clipped by transistors 39, 41 and diode 40. The next pulse at terminal T1 restores the state of the bi-stable circuit, reversing the conductive states of diodes 17, 18, 21, 22. Capacitor 15 now discharges via diode 22 and the constant current transistor 37, thus providing a second output pulse at terminal T2. Transistors 33, 37 provide the same value of constant current hence the duration of each delayed pulse is unchanged.

Dials and scales; roller-and-sheet recording apparatus.-In apparatus for indicating and recording physical conditions e.g. temperature, a constant speed motor M, Fig. 1, drives a commutator C and a roller 52 carrying the sheet P on which the record is to be made. Thermo-couples T, T1, Fig. 4, are switched alternately by the commutator C into co-operation with a mechanical relay which causes a rotation of the shaft 10 proportional to the temperature of the particular thermo-couple in action at the moment. Rotation of the pulley 46 carried on the shaft 10 moves the recording pin 49 as shown. A galvanometer V, employed for giving simultaneously an exact indication, has a second scale S1 which is movable so that the amount by which the temperature exceeds or falls short of a given value may be ascertained at the same time. A coloured lamp is caused by the commutator C tc glow when one thermo-couple is operative and t< remain dull when the other is.

Abstract: A stable high bulked filament bundle or yarn is characterized by a per cent denier increase of at least 10%, a bulked configuration such that the ratio of the product of the average diameter, in 0.001 mm. of the random crunodal loops in the outer filaments of the bulked filament bundle times the average diameter, in 0.001 mm. of the filament bundle core times the average number of crunodal loops protruding round the outer surface of the core per mm. length of the filament bundle to the bulked denier of the filament bundle is at least 1800, and a stability index no more than 0.1 times the per cent denier increase.  The stable bulked yarn may be produced by melt spinning a synthetic polymer to form a bundle of filaments, drawing the filaments, and overfeeding the filaments through a turbulent fluid jet, the process being characterised in that a finish comprised of an organic liquid having a surface tension not greater than 46 dynes/cm., a viscosity less than 75 cp. at 25 DEG C and a "boundary friction" at 20 DEG C not less than 0.15 is applied to the bundle of filaments before they are drawn, and after drawing, but before overfeeding, through the turbulent fluid jet the bundle of filaments is wetted with a liquid having a surface tension not greater than 75 dynes/cm. at 25 DEG C and a viscosity not p  greater than 3 cp. at 25 DEG C.  The finish may comprise an emulsifier and at least 15% by weight of a lubricant.  The lubricant may be an ester of a polyethylene glycol of molecular weight between 150 and 600 and an acid having the general formula R-COOH wherein R is an aliphatic hydrocarbon radical of 7 to 17 carbon atoms or an ester of a saturated aliphatic monohydric alcohol containing 2 to 5 carbon atoms in the molecule and an acid having the general formula R-COOH wherein R is an aliphatic hydrocarbon radical of 7 to 17 carbon atoms.  The finish may contain a lubricant comprised of a petroleum white oil having a viscosity of 8 cp. at 25 DEG C.  The liquid applied to the drawn bundle of filaments before feeding the bundle through the turbulent fluid jet should preferably have a viscosity less than 1 cp. at 25 DEG C and is preferably water.  Other suitable wetting agents are carbon tetrachloride, methanol, toluene and methylene chloride.  The method to be employed for determining the "boundary friction" of the finish is described.
