Title: Improvements in acetylation of cellulose
IPC: C08B3/06
Filed: 1962-10-22
Abstract: Cellulose is acetylated by contacting substantially dry fibres with acetic acid, limiting the amount of acid contained in the fibres to 10-60% by weight, by removal of excess acid if necessary; contacting the resulting swollen fibres with acetic anhydride at a temperature from ambient to 140 DEG C. and then subjecting the fibre to noncatalysed acetylation with superheated vapour of acetic anhydride at 150 DEG C.-220 DEG C. to form dry cellulose fibres having an acetyl content of up to 30% by weight.  The cellulose, in the form of wood pulp, cotton linters, mattes, webs, sheets or fabrics, may be sprayed with, or immersed in, the reagents in a continuous process or a batch process.  In one embodiment, a moving sheet of cellulose fibre is sprayed with acetic acid to swell the fibre.  The sheet is then sprayed with acetic anhydride while it passes over a suction box, causing displacement of a proportion of the acetic acid by the acetic anhydride, and also some acetylation.  The cellulose sheet, saturated with a mixture of acid and anhydride then enters a cloud reactor in which it is passed over a series of rolls and is contacted, e.g. for 15-90 minutes, with acetic anhydride vapour at 150 DEG C.-220 DEG C. The acetylated sheet retains its original form.

Abstract: 1,190,913. Three dimensional cinematography; halography. COLUMBIA BROADCASTING SYSTEMS INC. June 15, 1967 [Sept. 8, 1966], No.40202/66. Headings G2C; G2E and G2J. A projection screen 1 is made as a "deep" hologram for use in the projection of three-dimensional colour of monochromatic pictures using white light, comprises a photographic medium with a resolving power at least equal to a wavelength of light (about 0.5 micron) and several wavelengths thick, say 20- 40 microns, the medium being first exposed to coherent radiation converging towards an image of a first projector Pr I simultaneously with coherent radiation issuing from images of viewing zones associated with the first projector, and secondly being similarly exposed in relation to a second projection, Pr II. Left and right-eye pictures are projected on to the concave screen 1 by the two projectors in white light, Pr II being optically displaced by mirrors M 1  M 2 , and are viewed as a steroscopic picture, without spectacles or other aids by viewers within zones consisting of parallel strips extending back from the screen. These strips are the inter-ocular spacing in width and may consist of spaced or continuously extending L and R pairs. The exposure in turn of the rear face of the screen to light converging towards each projector is achieved by the optical system of Fig. 6 (not shown), segments of the screen being exposed and developed in succession. Light from laser (6) is split into two beams, one being focused towards virtual image (Pr) by lenses (4, 5) on either side of screen (1), or the other being focused on the screen by lens 5 as an image of a model 15 of the viewing zones of the auditorium. The model may be a diffusing screen masked to produce the zones. The angular separation of the projectors # is given by 1 # (/nd)<SP>2</SP> where = vacuum wavelength of light n = refractive index of emulsion d = thickness of photo-sensitive layer.

Filed: 1968-08-22
Abstract: 1,192,876. Synchronous demodulator. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 22 Aug., 1968, No. 40219/68. Heading H4F. A synchronous demodulator for use in PAL systems is constructed in the general manner shown in Fig. 1 wherein elements 1 to 10 denote active devices and elements 11 and 12 denote load impedances and is such that it is particularly suitable for use with integrated circuit techniques. The demodulator is for use in systems wherein the quadrature colour components are each demodulated separately, the demodulator of this invention operating only on the alternating component. Elements 4 to 8 form a balanced demodulator, while elements 9 and 10 form a multivibrator operating at line frequency to switch the supply from terminal 14 alternately to elements 1, 3, 5 and 6 and 2, 4, 7 and 8 on successive lines. Elements 1 and 2 are fed with a first phase of the quadrature modulated signal while elements 3 and 4 are fed with the opposite phase of said signal. Similarly a second phase of a reference signal, derived from the colour burst signal, is fed to elements 5 and 7 while elements 6 and 8 are fed with a reference signal of opposite phase. Alternatively elements 1, 2, 3 and 4 may be fed with the reference signal and elements 5, 6, 7 and 8 fed with the quadrature modulated signal in a similar manner to that above. In this way, the reversal of phase on successive lines of one of the colour difference signals is taken care of. The circuit also includes a colour killer comprising a transistor (22) (Fig. 2, not shown) interposed between the supply terminal 14 and the multivibrator which is cut off when no colour signal is present.

Title: Polymerization process
IPC: C08F297/02
Filed: 1959-11-30
Abstract: Graft polymers are prepared by polymerizing an ethylenically unsaturated monomer B in the presence of an anionic catalyst, and a polymer A, containing other atoms in addition to carbon and hydrogen and on to which monomer B will graft polymerize, is added either initially or after the beginning of the process but before the polymerization of monomer B has been completed.  The process may be carried out in the following ways: (a) the catalyst is first reacted with polymer A which is then brought into contact with the monomer; (b) polymer A is added to a mixture of monomer and catalyst before or during polymerization of the monomer, and (c) the monomer is first polymerized under the action of the catalyst to form a "living polymer" to which polymer A is added. Monomers B specified are styrene, alpha-methyl styrene, vinyl naphthalene, isoprene, butadiene, esters, amides and nitriles of acrylic, methacrylic, crotonic and methylene malonic acids and vinyl and isopropenyl methyl ketones.  Polymers A may be derived from the esters, amides, nitriles and anhydrides of acrylic, methacrylic, crotonic, maleic, fumaric and itaconic acids, vinyl and isopropenyl methyl ketones, chlorostyrene, aminostyrene, glycidyl allyl ether and mixtures of ethylene and carbon monoxide. The examples describe the preparation of polystyrene-polymethyl methacrylate graft polymers with the aid of naphthalene sodium as a catalyst.

IPC: H04M1/272
Filed: 1964-10-06
Abstract: 1,086,734. Impulse transmitters. GENERAL ELECTRIC CO. Ltd. Oct. 4, 1965 [Oct. 6, 1964], No. 40708/64. Heading H4K. In a key-operated impulse transmitter in which telephone number digits are successively stored in a mechanical store and transmission of the digit impulses to line begins as soon as the first digit is stored, the mechanical store comprises a squirrel-cage type assembly of spring-loaded conductor wires 5 stretched between two end plates, and passing through cut-outs 14 in the periphery of ten discs 10 of conducting material spaced along the axis of the assembly. Each wire corresponds to a digit position in the number and each disc a digit value. Depression of a particular digit key 21 causes the wire beneath it to be deflected by means of the associated one of ten levers 26 and latched under the lip 18 of the disc associated with that key, so making contact with that disc. The wire now stores a digit value according to the disc to which it is latched. Upon the release of the key the ratchet mechanism 33- 37, previously depressed, rotates the drum to present the next wire to the levers 26. After keying up the first digit a rotary switch begins to supply earth to each wire in turn which via the particular wiped disc 10 earths one of ten terminals of a pulse generator to supply the appropriate number of pulses. To assist in latching the wire around the lip 10, an insulating disc 11 adjoins each conducting disc 10 and has slightly smaller cut-outs with a lip 16 having a sloping front edge. To ensure only one disc is latched up by a lever, insulating discs are placed between the discs 10 and have notches around their edges in which the wires rest. The wires are unlatched prior to coming beneath the levers 26 by the mechanism 45 to 48. A pair of cam-operated contacts enable the pulse generator, the cam being stepped away, leaving the contacts closed, as the drum rotates but stepped back as digits are transmitted. A cancel key is provided which steps the cam back to its home position whilst preventing the transmission of pulses. Less than ten discs may be used, each key then latches up a unique combination of portions of the wire.
