C. mains supply through Rec 1 --- Rec 6, inverting the resultant D. C. to square waveform A. C. of different voltage from and substantially higher frequency than the A. C. mains supply by using semi-conductor controlled rectifiers SCR A , SCR B  and a transformer MT, and finally rectifying this high frequency A. C. through Rec 7, Rec 8. The D. C, voltage is maintained constant at a predetermined value by varying the firing instant of rectifiers SCR A , SCR B , using a detector bridge circuit D whose error signal is combined with the output of a saw-tooth waveform oscillator SO and applied to a Schmitt trigger circuit ST feeding the rectifier control electrodes through a binary flip-flop circuit FF. Circuit ST also feeds a blocking oscillator BO which supplies pulses to a transformer T to switch off the rectifiers SCR A , SCR B , the frequency of these pulses and hence the frequency of the inversion stage being determined by the frequency of the oscillator SO. . This latter frequency also determines the value of the D.C. voltage. Diodes DÝ, D 2 ' prevent mal-operation of the oscillator BO by pulses produced when the rectifiers SCR  A , SCR B  become conductive.

Title: Production of animated pictures
IPC: G03B15/08
Filed: 1960-12-19
Abstract: 929,676. Production of animated pictures. H. FREUDENHEIM, and J. D. CHAMBERS. Dec. 19, 1961 [Dec. 19, 1960; March 30, 1961], Nos. 43613/60 and 11839/61. Classes 97 (1) and 98 (2). In a process for producing animated pictures in recorded form, several identical sets of transfers are made from a set of original drawings comprising representations of a cycle of successive positions of the picture element in a movement which because of its recurrence in different contexts, for example in various positions and movements of other picture elements, can be treated as a unit in the animation process, and the sets of transfers are used to create the corresponding unit movement in the animated sequences by applying transfers of a set to individual supporting sheets to produce transferred images at desired locations onthe sheets. As an example, a number of drawings of a leg are made in all the positions necessary to produce an animated picture sequence of the walking of a leg. Several identical sets of transfers from these drawings are then produced and applied to individual supporting sheets in juxtaposition to other picture elements (e.g. a body portion and other limbs, transfers of which may be prepared in the same manner) to produce the desired animated picture sequences. A library of transparencies may be collected. Transparent support sheets, each with a part (e.g. a single character) of a complete picture formed thereon from transfers may be laid in superposition over a background sheet bearing a desired stationary background scene. Successive assemblies of sheets may be photographed to produce animated film strips or the sheets themselves may comprise parts of a continuous strip. For television applications, the pictures may be recorded on magnetic tape. The transfers may be coloured. Opaque transfers may be produced for use in the travelling matte process. Transfers may be applied directly to the pages of a " flicker book " or the sheets on which the transfers are supported may be bound to form such a book. Alternatively, successive pictures may be printed on to the pages of a flicker book using plates prepared photographically from assemblies of transparencies on transparent support sheets.

Title: Novel dyeing process
Inventor: SMITH NORMAN BRIAN
IPC: D02J1/22
Filed: 1960-12-28
Abstract: A continuous integrated process for the colouration of filaments melt spun from synthetic linear polymers comprises applying a dye or optical whitener dissolved without dispersing agents or diluents in at least one hot organic substantially non-aqueous solvent to the undrawn filaments having a birefringence of less than 10 X 10-3 under conditions such that penetration of the dye into the filaments is 60% of the cross-sectional area or more followed by drawing the filaments to 3-6 times their original length.  In a preferred embodiment of the invention <FORM:0921125/IV(a)/1> where Cf, the concentration of dye in the fibre, is 2 or more, Cs, the concentration of dye in the solvent, does not exceed saturation and K is a constant, preferably between 0,2 and 1,6.  Specified solvents are ethylene glycol, diethylene glycol, polyglycols and ethylene oxide condensates of molecular weight 200-6,000 and their esters and ethers, dimethyl and diethyl sebacate, oleic acid, mesitylene, triphenyl phosphate and glycerol or mixtures thereof all of which are suitable for use at 100 DEG -150 DEG C.  Additionally specified are trichlorethylene, carbon tetrachloride, acetone, benzene and glacial acetic acid which are suitable for use at or near their boiling points.  The preferred contact time in the solution is 5-15 seconds.  The linear polymers may be polyolefines, polyamides and polyesters including polyethylene terephthalate and its copolymers with polyethylene sebacate.  The classes of dyestuff suitable are the unsulphonated bases of acid wool dyes, oil soluble or vat pigments and especially disperse dyes.  The filaments are preferably treated as a tow which may be impregnated with the dye solution in a pad-mangler controlled to an increase in weight of 25-35% and thereafter maintained at an elevated temperature for the required dyeing time.  A suitable apparatus for the process comprises a pad-mangling system for applying the dye solution and a draw frame for drawing the filaments, side plates and means for heating and maintaining the padding bath at the correct temperature and level, the feed rolls of the draw frame being driven at the same speed as those of the pad-mangler while the draw rolls are driven 3-8 times faster than the feed rolls with means for heating the filaments and means for removing excess dye solution and means for winding or forwarding the dyed and drawn filaments.  Preferably there is a thermostatically controlled heater tube vertically below the pad mangle whose atmosphere may be kept saturated with solvent by a drip device.  After removal of excess dye liquor the wet filaments may be crimped, dried and heat-set in a relaxed condition and, if desired, cut into staple fibre lengths.  Examples of producing coloured filaments of polyethylene terephthalate are given.

Abstract: 1279736 Chromatographic apparatus; contact apparatus RESEARCH CORP 9 Sept 1969 44536/69 Addition to 1175736 Headings B1F and B1X Cylinders 214, 216 are coaxially mounted so as to define between the cylinders and annular passage 212 which is 0.00004-0.25 in. wide. The surfaces of cylinders 214, 216 defining the passage are coated with a suitable chromatographic adsorbent which may in turn be coated with a suitable liquid stationary phase, such as dioctyl phthalate (applied as a 5% solution in benezene). The mixture to be separated is passed along line 238, through slip ring 240 and through one or more of inlets 248a, b, c &c. in the upper wall of outer cylinder 216. Carrier gas flows along line 222 and through passage 212 via passages 230, 232, causing the components of the mixture to be separated in time in arriving at one or more of outlets 260a, b, c &c. located in the lower wall of outer cylinder 216, and which connect with corresponding output lines 258a, b, c, &c. through silp ring 250. The apparatus may be used for continuous preparative separation by rotating the unit through the agency of drive belt 270 and pulley 266, such rotation causing successive doses of mixture to be deposited at the top of passageway 212 as apertures 248a, b, c, &c. come successively into alignment input line 238 through slip ring 240. By suitable adjustment of the rate of rotation, particular components of the mixture may be removed through particular apertures 260a, b, c, &c. as they come into alignment with particular output lines 256a, b, c, &c. through slip ring 250. Using such an apparatus, the separation of a benzene/toluene mixture at 120C. is described, using helium as carrier gas. In another embedment (see Figs. 4 and 5, not shown), a similar unit in which the cylindrical surfaces are replaced by frusto-conical surfaces is described. The apparatus may be adapted to operate as a catalytic reactor in which the catalyst is the coating on the cylindrical or frusto-conical surfaces. Such a reactor is of particular application in reactions in which either the equilibrium constant is low or in which a product is strongly adsorbed by the catalyst by removing the product from the reaction site.
