Title: Process for preparing crystalline polymers,the polymers so prepared and articles made therefrom
IPC: C08F297/08
Filed: 1962-11-21
Abstract: A solid crystalline polymer of ethylene and propylene is obtained by initially polymerizing one of such monomers to obtain a preformed polymer, and then polymerizing the other monomer in the presence of said preformed polymer until a polymer containing more than 99% but not more than 99.9% by weight, of polymerized propylene, which is substantially free from homopolymer, is formed.  The ethylene propylene polymer has a density of at least 0.87 and an inherent viscosity in tetralin at 145 DEG  C. no greater than 2.4.  All of the polymerization is carried out at a temperature from 130 DEG  to 300 DEG  C., under a pressure of 1 to 2000 atmospheres and in the presence of a solid stereospecific high temperature polymerization catalyst comprising a halide of a transition metal in Group IV (b), V (B) or VI (B) (Lange's Table) preferably in a reduced valency form, and a metal of Group I (A) or a hydride or complex hydride of a Group I (A) metal.  A third catalyst component selected from halides of alkali metals, magnesium oxide, aromatic ethers, hydrides of sodium and potassium and alcoholates or oxides of sodium, potassium, lithium, calcium, magnesium, barium, strontium, aluminium, titanium and zirconium, may also be present.  Preferably propylene is polymerized first. The polymerization can be conducted in stages in a single reactor having separate reaction zones or in separate reactors arranged in series.  In the examples: (1) propylene is polymerized in mineral spirits using lithium aluminium hydride, sodium fluoride and titanium trichloride and then ethylene is added and the polymerization continued; and (2) a continuous two-stage reactor system was used employing a catalyst as in (1). By thermally degrading the polymers low molecular weight liquid and waxy polymers are produced.

Title: Improvements in methods for making fiber optical image transfer devices
IPC: C03B37/15
Filed: 1963-11-05
Abstract: <PICT:0986742/C1/1> <PICT:0986742/C1/2> In a method of making a fused fibre optical image-transfer device embodying a multiplicity of light-conducting optical fibres each having a cone of light-transmitting material of a high refractive index and a cladding of light-transmitting material of a lower refractive index in which gases are dissolved, the fibres being arranged in a bundle in side-by-side relation so that corresponding ends of fibres define mosaic faces at respective opposite ends of the bundle, there is established and maintained a super-atmospheric fluid pressure in a zone surrounding the fibre handle, the fibres being heated to fusion temperature and then being compressed within the pressure zone so as to fuse the fibre claddings together in a vacuum-tight relation to each other.  A bundle of fibres 24 (Fig. 5) is placed in a flanged sleeve 26 within a sealed chamber 30.  A compression piston 42 is positioned at the mouth of the sleeve 26 and the chamber 30 filled with an inert gas, e.g. helium or argon, through nipple 40 at a pressure of the order of 1000 p.s.i. this being substantially in excess of the vapour pressure of any gases tending to escape from the glass fibres.  A heater 50 causes the bundle to be fused slowly from the base upwards, pressure being applied by the piston 42.  Thus the fibres bulge outwardly as at 56 (Fig. 7) progressively from their bases upwards into an intimately fused relationship with adjacent fibres, so closing the interstices 54 between fibres and tending to expell any gases collected therein.  The gas used to maintain the pressure zone may be one which is soluble in the fibre cladding so as to prevent any bubble formation. The fibre core may be a barium flint glass of refractive index 1.66 and the cladding a soda lime glass of refractive index 1.52 fused together at 1150 DEG  F.

Abstract: 1437328 Television RCA CORPORATION 21 Sept 1973 [25 Sept 1972] 44295/72 Heading H4F [Also in Division H1] The signals derived by an array of photosensitive elements S 11 -S 34  are read-out in parallel, in response to transfer pulses, to associated points N 11 -N 34  in charge-transfer registers CR 1 -CR 4 , the resulting signals being transferred out of the registers to output register 12 and thence to an output terminal 14 from where they may be transferred via a gating circuit 13 to an output amplifier 15 and/or an amplifier 16 from which the signals are fed back to an input register 18 and thence to the registers CR 1 -CR 4  so that each signal is fed back to the point N 11 -N 34  corresponding to the photosensitive elements, S 11 -S 34  at which it was produced; this may be used to compensate for dark currents produced by the photosensitive elements, as a moving target indicator, or as an image store. For normal read-out the signals at the register output 14 are fed to output amplifier 15 and no feedback takes place. For dark current compensation the array receives light only during alternate frames, the signals derived in the intervening frames, when light to the array is blocked, being fed back via feedback amplifier 16 acting as an inverting amplifier, signals being fed to output amplifier 15 every second frame, these signals being the difference between the signals produced by the array when receiving light and the "dark" signals produced when the array receives no light. The "dark" signals may alternatively be stored and fed, via switch S 3 , to the registers CR 1 -CR 4  simultaneously with the scanning of the array, the array receiving light during all frames. For moving target indication the array is continuously illuminated, the signals at the register output 14 always being fed to output amplifier 15 and to feedback amplifier 16 acting as an inverting amplifier, the output signals representing the difference between the signals developed by the array during successive frames.  For image storage the array is illuminated for only one frame, the signals at register output 14 always being fed to output amplifier 15 and to feedback amplifier 16 acting as a non-inverting amplifier. Alternatively signals introduced via switch S 3  may be transferred from the change transfer registers CR 1 -CR 4  to the photosensitive elements S 11 -S 34  to be stored there and subsequently combined with generated signals. An additional output amplifier 29 receiving the output of feedback amplifier 16 may be included. The photosensitive elements may, for example, be photodiodes or phototransistors.
