Abstract: Thermosetting aminoplastic copolymers are prepared by copolymerizing compositions comprising (1) at least one unsaturated-alkylated-urea-aldehyde resin, and (2) at least one ethylenically unsaturated monomer or partial polymer of such a monomer.  As components (1) there are used resinous reaction products of a urea-type amino compound, e.g. urea, thiourea, biuret, dicyandiamide, and/or guanidine, an aldehyde, e.g. formaldehyde, acetaldehyde benzaldehyde, and/or unsaturated aldehydes such as acrolein or crotonaldehyde, and an unsaturated aliphatic alcohol, e.g. allyl, methallyl, crotonyl, linoleyl and/or linolenyl alcohol. As components (2) there are used for example vinyl acetate, diallyl phthalate monomer and prepolymer; the methyl, ethyl, n-butyl, isobutyl, 2-ethoxyethyl, nonyl and lauryl esters of acrylic and methacrylic acid; unsaturated acids and anhydrides such as maleic anhydride, methacrylic, itaconic and fumaric acid; monoalkyl esters of dibasic unsaturated acids; styrene, methylstyrene, vinyltoluenes, and chlorine-substituted derivatives thereof; unsaturated polyester-alkyd resins and mixtures of these with other unsaturated materials such as esters and partial esters.  The copolymerization of the mixture may be carried out by bulk, solution, or emulsion polymerization processes, with the application of heat, and/or the addition of catalysts, e.g. methyl ethyl ketone peroxide or benzoyl peroxide, promoters e.g. cobalt naphthenate, inhibitors, e.g. hydroquinone, driers and/or accelerators, if desired.  Plasticizers and modifiers, e.g. high-boiling esters, polyesters, plasticizing alkyds, unsaturated polyester alkyds, drying and semi-drying oils, acids and alcohols therefrom, oil-modified alkyds, styrenated drying oils, natural rubber, terpenes, air-drying amino-triazine based compositions, and/or styreneated oil-modified alkyds may be added at any stage during manufacture. According to the degree of copolymerization the products may be used for coating and impregnating compositions in solution or emulsion form, for casting, moulding and laminating compositions, adhesives, and the manufacture of articles such as foils, films and monofilaments.

Filed: 1925-12-03
Abstract: 250,902. Soc. d'ElectricitÚ de Paris April 16, 1925, [Convention date]. Grates. - The space between the upper and lower runs a', a, Fig. 1, of a travelling chain grate is divided into compartments o', o<2> - - - by partitions c<1>, c<2> - - - each constituted by a number of partitions c which extend downwardly towards the lower run a so as to leave spaces to allow for the passage of parts of links which may be broken and adhere to the pivot pins. Leakage of air from one compartment to another beneath the partitions c is prevented by freelyrotatable tubes T in one or more parts arranged between the partitions and resting on the lower run of the grate. A spacer-bar e attached to the side frames passes through each tube. The lower run of the grate rests upon a plate band carries any fuel falling through the upper run towards the front of the grate. In each compartment and along each of the lateral edges of the run a is arranged a sheet-metal flap formed in two parts g, g<1>, Figs. 1 and 3, secured to bars h, h<1> pivoted at i, the bar h<1> being turned up at one end and pivoted at l. The flaps rest upon the run a and prevent any appreciable leakage of air from one compartment to another. In the event of a broken link striking the flap, the latter turns about the pivot l and assumes the position indicated in dotted lines to allow the passage of the broken link. Air is supplied to the compartments through openings d when working under forced draught, but when using natural draught air may be supplied through controlled openings p in the guide-plate b. Instead of the flaps g, g<1> metallic brushes or flanges may be arranged to fill the gap between the frame and run a.

Title: Improvements in heat exchangers
IPC: F28F7/02
Filed: 1962-08-10
Abstract: 947,459. Heat exchangers. UNION CARBIDE CORPORATION. Aug. 10, 1962 [Aug. 11, 1961], No. 30699/62. Heading F4S. A heat exchanger for two fluids comprises two headers 10 and 12 made from monolithic blocks of impervious graphite, each header having rows of drilled passages 18 whose axes are all parallel one with another, the two fluids passing through separate rows of passages. As shown, Fig. 1, the headers 10 and 12, a block 14 also of impervious graphite, and intermediate gaskets 50 and 52 have correspondingly drilled passages 18 and are clamped together by means of pressure plates 20 and 22 and tie-rods 24. The headers are protected by pressure pads 46 and 48. Horizontal machined grooves 19 across the adjacent faces of the headers and the block 14 between each row of passages 18 allow any fluid leaking from the passages, due to faulty gaskets, to pass to the external surface of the heat exchanger to provide visible leak indication and to prevent mixing of the two fluids. The headers 10 and 12 are identical in a heat exchanger having an odd number of passes for each fluid. Fluid " A " enters header 10 through an inlet 34 and passes through a tapered conduit 58 to feeder conduits 62 at the level of alternate rows of passages 18, and enters half the passages 18 by branch conduits 64. It leaves the header 12 through a similar conduit system leading to an outlet 44. Fluid " B " enters header 12 at an inlet 32 and is lead by conduits, not shown, to one-third of the remaining half of the total number of passages 18, and makes three passes through the heat exchanger in the rows intermediate of those carrying fluid " A." Fluid B leaves the header 10 through an outlet 42. All internal conduits in the headers are blind drillings plugged at the external surfaces of the blocks, the vertical drillings 58 and 72 being tapered. The heat exchange surface can be varied by having no block 14, or by adding further blocks 14, while the internal flow paths of the fluids may be subject to many possible variations by suitably arranging the drilled conduits in the headers. The heat exchanger is particularly suited for use with corrosive fluids.

Title: Generating a Signal having a Phase Determined by a Burst of The Same Frequency.
Inventor: ROUT ERIC RAYOMD
IPC: H04N9/455
Filed: 1967-07-04
Abstract: 1,173,518. Colour television. BRITISH BROADCASTING CORP. 16 July, 1968 [4 July, 1967], No. 30804/67. Heading H4F. A method of producing a continuous signal at a given frequency which has an instantaneous phase equal to that of the last received of a series of bursts of said frequency, may be applied to the processing of N.T.S.C. signals produced at the output of a standards converter as described in Specification 1,052,438. In such signals the subcarrier bursts are not necessarily spaced from each other by equal line intervals and so their phases can be substantially different. The use of a standard phase lock local generator for producing the colour signal demodulation subcarrier is thus difficult, and the method of the invention produces a subcarrier which follows the burst phase variations. The bursts are thus gated through 11 and applied to synchronous demodulators 12A and 12B where they are demodulated by a subcarrier frequency reference signal directly and via a 90 degree phase shifter 14. The outputs of the demodulators represent respectively the amplitudes of the components of the burst in phase with and in phase quadrature with the reference signal. Said outputs, which only occur during the bursts, are stored for the ensuring line period in respective sample and hold circuits 15A and 16B. These may each comprise a storage capacitor across the output terminals, and an electronic switch, closed during the burst interval, between the input terminal and the capacitor. The charge on each capacitor is used to amplitude modulate the direct and 90 degree phase shifted reference signal in modulators 16A and 16B respectively. The outputs of the modulators are summed at 20 to produce the desired continuous phase following subcarrier.

Abstract: Anti-fogging compositions for coating thermoplastic materials, e.g. polyethylene films, comprise (a) an alkali metal salt of a C5- 10 diester of sulphosuccinic acid, and (b) a C12- 18 fatty acid monoester of a polyhydric alcohol. Examples of (a) are sodium dioctyl or dihexyl sulphosuccinate, and of (b) are glyceryl monostearate, and a mixture of glyceryl and mannitan laurates. These components are usually dissolved or dispersed in a solvent, e.g. a C1- 5 alcohol or an ester thereof with a C1- 5 acid, e.g. n-propyl acetate. The compositions may also contain finely divided (e.g. 0.1-5 microns) polyvinyl chloride. In an example, a typical composition also contains an overprint varnish comprising a mixture of nitrocellulose and shellac in a solvent mixture of lower alcohols and esters.ALSO:Films and sheets of thermoplastic polymeric materials are coated with an anti-fogging composition comprising (a) an alkali metal salt of a C5-10 diester of sulphosuccinic acid, and (b) a C12-18 fatty acid monoester of a polyhydric alcohol, optionally together with (c) finely divided polyvinyl chloride, and preferably dispersed or dissolved in a lower alcohol or ester solvent, e.g. n-propyl acetate.  Many polymers to which the compositions may be applied are described, in particular bi-axially oriented polyethylene film which has been cross-linked by irradiation.  Prior to coating the film may be treated to improve the adhesion of the composition to its surface, e.g. by corona or electric discharge or flame treatment. The coated films are particularly useful for wrapping moisture-containing foods such as fresh meat, poultry and vegetables.

Title: Improvements in or relating to calculating and the like machines
IPC: G06C21/04
Filed: 1932-11-04
Abstract: 395,558. Calculating-apparatus. BURROUGHS ADDING MACHINE CO., 2nd Avenue, Detroit, Michigan, U.S.A. Nov. 4, 1932, No. 31134. Convention date, Jan. 2. [Class 106 (i).] In a key-set and independently operated machine certain banks of the keys are used for designation purposes and the operating mechanism is conditioned for operation only when the keys in the designation banks are depressed. The conditioning mechanism includes control members which are interchangeably associated with the key banks so as to enable the control on the operating mechanism to be varied. The invention is shown applied to a machine with an operating shaft and disconnectible driving connections with a drive shaft as described in Specification 265,122, [Class 106 (i), Calculating &c.]. The machine may be operated manually or automatically by a motor as described in Specification 265,135, [Class 106 (i), Calculating &c.]. The drive shaft 20, Figs. 1 and 3, has an arm 30 normally engaging a pawl 33 on the full stroke sector 35 whereby the machine is given an operation. At the start of each operation, when the machine has been properly conditioned, an arm 43 is rocked to displace a member 40 so as to withdraw the nose 41 thereon out of the path of a projection 42 on the pawl. The member 40 is normally blocked by an arm 50 of a yoke member 51 another arm 55 of which is bifurcated to engage a projection 56 on a spring controlled bail member 57 extending across the machine and pivoted to a shaft 58. The bail is restrained from movement until the proper designation keys have been depressed by reason of the connection of upstanding lugs 60 on the bail with the hooked ends of corresponding slide plates 61. These hooked ends are large enough to permit the plates to move forward when the keys are depressed. The plates co-operate with the keys through projections 63 and are interchangeable for adaptation to any desired key bank. In operation, after depressing the item keys, the designation keys are depressed to move the slide plates forward whereupon the bail is released and under the action of its spring 59 rocks the yoke arm 50 to free the disconnecting member 40. The usual bank of control keys 11 is also provided with a slide plate 70 normally positioned so that the rear of the hooked end engages its lug 60. When any one of the control keys such as the total or sub-total key is depressed the bail 57 is forcibly rocked against the action of the springs 64 controlling the slide plates 61 to operate the bail 57 and free the member 40. The actuating sectors in those banks selected for designating purposes may be left blank so as not to engage the totalizer pinions.
