Abstract: 1,035,511. Radix converters. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. April 14, 1964 [Jan. 18, 1963], No. 2335/63. Heading G4A. In a radix converter, a matrix of modules each responsive to dividend and carry input signals and providing output signals representing the quotient and remainder when a number according to a first radix is divided by a second radix, the remainders from each repeated division represent the number according to the second radix. In a decimal/binary converter the decimal digits are fed in decreasing orders of significance to successive rows of modules (Fig. 1, not shown), a relay A, B or C being energized when a remainder is generated which controls the corresponding division process on the digit of next significance, until the final remainder outputs from the columns represent the binary equivalent. Modules 12, 13, 14, 15 are identical replaceable units. The remaining parts 16, 17 are degenerate forms of the modules and are each accommodated on a single board. In a binary/decimal converter, the binary number is first divided by two which only changes its significance and then is divided, according to the invention, by five using the circuit of Fig. 3 (not shown) as a module in the matrix. The modules may be electromagnetic relay circuits or transistorised circuits (Fig. 7, not shown).

Filed: 1918-02-14
Abstract: 122,720. Selvey, W. M. Feb. 14, 1918. Heating buildings.-The circulation water from the condenser of a steam-power plant is further heated to render it available in a hot water supply or heating system by steam, the temperature of which has been lowered below that corresponding to atmosphere pressure by use as a motive flud. The cooling water from the condenser d of a turbine is passed through an auxiliary condenser c receiving steam from intermediate stages of the turbine. The heated water flows into a reservoir f and then through separators g into a reservoir h, from which it is drawn by pumps and forced through the pipes k, l of the supply or heating system n. Make up water is supplied to the return pipe l<1> of the system through a branch q from the main. The water may pass through an independent section d' of the condenser, the body of the condensing water being drawn from the pond s of the cooling tower. The temperature of the water passing through the auxiliary condenser may be maintained constant by thermostatically-operated valves which so control the supply of steam that it is drawn from a higher or lower belt of the turbine. The reservoir f may receive hot water heated by waste heat from other sources.

Title: Improvements in or relating to the colouration of materials comprising cellulose derivatives
IPC: D06P3/34
Filed: 1928-01-30
Abstract: 310,827. British Celanese, Ltd., Ellis, G. H., Olpin, H. C., and Mosby, D. H. Jan. 30, 1928. Azo dyes containing the anthraquinone nucleus are used for dyeing, printing, stencilling, or otherwise colouring materials made of or containing organic substitution derivatives of cellulose by the application of the dystuffs in substance. Such dyestuffs may be obtained by coupling diazotized primary aminoanthraquinones or derivatives thereof with components such as p-xylidine, cresidines, anisidines, m-toluidine, m-phenylenediamine, nitro-m-phenylenediamine, phenol, maminophenol, monoacetyl-m-aminophenol, dimethyl-m-aminophenol, 1 (or 2)-naphthylamine, #-oxyethyl-1-naphthylamine, gamma-chlor-#-oxypropyl- 1-naphthylamine, 1-amino-2-methoxynaphthalene. The anthraquinone nucleus may contain, in addition to the group or groups necessary for the formation of the dyestuff, other substituent groups, e.g. carboxyl, alkyl, halogen, amino, alkylamino, acidylamino, nitro, hydroxy, alkoxy, or mercapto groups. A table is given showing the shades obtained with the following dyestuffs -1-Aminoanthraquinone # phenol, m-toluidine, o-anisidine, m-phenylenediamine, or anthranilic acid; 1-amino-2-methylanthraquinone # phenol, m-toluidine, dimethyl-m-aminophenol, or m-phenylenediamine; 1-aminoanthraquinone-2- carboxylic acid # m-toluidine; 1-amino-4-oxyanthraquinone # phenol, w-toluidine, or mphenylenediamine; 1: 5-diaminoanthraquinone # phenol or m-toluidine; 1: 5-diaminoanthraquinone # phenol (1 mol.) and m-toluidine (1 mol.); 1: 8-diaminoanthraquinone # phenol, m-toluidine, or m-phenylenediamine. Dyestuffs insufficiently soluble in water may be applied in aqueous suspensions or dispersion obtained e.g. by colloidal grinding, by dissolving in a solvent and mixing with water containing, if desired, a protective colloid, or by pretreating with dispersing agents, such as those described in Specifications 219,349, 224,925, 242,393, 242,711, 269,960, 273,819, and 273,820. If the dyestuff contains a diazotizable amino group it may be diazotized on the material and developed. The following examples are specified :-(1) A cellulose acetate knit fabric is dyed yellow by treatment in a dyebath containing a dispersion of the dyestuff 1-aminoanthraquinone # m-toluidine obtained by mixing a finely ground aqueous paste of the dyestuff with the product of sulphonation of a mixture of naphthalene and oleic acid. (2) Cellulose acetate yarn in hank form is dyed orange by treatment in a dyebath containing a dispersion of the dyestuff 1-amino-2-methylanthraquinone # dimethyl-m-aminophenol obtained by mixing or grinding the dyestuff with sodium sulphoricinoleate. (3) Cellulose acetate knitted goods are dyed golden orange by treatment in a dyebath containing the ammonium salt of the dyestuff 1-aminoanthraquinone # anthranilic acid. y-Chlor-#-oxypropyl-1-naphthylamine is obtained by condensation of 1-naphthylamine with epichlorhydrin.

Title: Improvements in the manufacture of tyres
Inventor: FLETCHER HENRY RAYMOND
IPC: B29D30/10
Filed: 1958-01-29
Abstract: 906,538. Building pneumatic tyres. DUNLOP RUBBER CO. Ltd. Jan. 26, 1959 [Jan. 29, 1958], No. 2913/58. Class 144 (1). A pneumatic tyre is built by first forming a flat band carcase 17 on a building drum comprised of two axially-spaced, coaxial, mutually approachable end parts 1, 2 which serve to receive and shape the beads 9 and lower sidewall regions of the carcase into substantially their final shape, and then applying pressure to the inner surface of the crown region of the carcase whilst simultaneously approaching the end parts 1 and 2 towards each other so that the carcase is shaped into toric form to contact a tread 19 and breaker 18 centred around the carcase. As shown, the end parts 1, 2 form the shoulders of a high crown former and are connected by rotatable screws 4 which engage inner peripheral rings 3 of the parts 1, 2 with respectively opposite-hand screw engagement whereby rotation of the screws 4 effect simultaneous approach or receding movement of the parts 1, 2. The screws 4 are journalled in spiders 7 which are mounted on the drum shaft (not shown) and when the carcase band is completed the spiders 7 are removed in turn to permit the assembly of bead-clamping rings 11, 12 against the carcase beads 9. The rings 11, 12 have sealing engagement on the drum shaft and the ring 11 has an entry 16 for the supply of pressure air to shape the carcase. The required shaping may, however, be achieved centrifugally instead of by inflation. The tread 19, and breaker 18 if fitted, may be centred around the carcase in a segmented removable ring 20 which may be internally recessed to receive the tread either as shown in Fig. 3, or sufficiently to carry the tread in its shaped condition when on the finished tyre. In alternative embodiments, a removable rigid centre portion may be inserted between the end parts 1, 2 to support the carcase plies during building thereof, the centre portion being removed prior to the shaping operation, or a flexible rubber diaphragm may be stretched between, and clamped to, the end parts, the pressure air being introduced through the diaphragm to act directly on the carcase when shaping the tyre.

Title: Method for removing moisture from non-rigid elastomers
IPC: B29C48/395
Filed: 1962-01-26
Abstract: 965,183. Drying non-rigid elastomers. INTERNATIONAL BASIC ECONOMY CORPORATION. Jan. 26, 1962 [Feb. 17, 1961], No. 2972/62. Heading F4G. [Also in Division B1] In apparatus for drying non-rigid elastomeric material, the material passes through an elongated enclosure with gradually increasing pressure and temperature until a sudden escape of the material from the zone of highest pressure in the enclosure to one of reduced temperature and pressure outside induces instantaneous flash evaporation of moisture in the material and cooling thereof. In a process for preliminary dewatering and drying natural, synthetic and reclaimed rubbers, the material in slurry form passes from a belt 20, Fig. 1, through a preliminary extrusion drier 22 to reduce the water content to between 5 and 20% by weight, and then passes to a drying unit 23, Fig. 6A, in which the material is increasingly compressed by a shaft with compression worms 69, 70, 71 &c. and inwardly extending breaker bolts 77 and heated by a steam heated jacket (not shown). The material is thus compressed and heated until it passes through discharge openings 80 in a removable insert 82, in a dieplate 79, the sudden drop in pressure and temperature inducing flash evaporation of water from the material and also a cooling of the material. A thermocouple (not shown) is inserted in the die plate 79 to sense the temperature of the elastomer and is utilized to control steam admission to the jacket in accordance with the requirements and cutter means (not shown) adjacent the exit reduce the issuing material to limited size. Steam or other vapour or gas under pressure may be introduced into the imperforate barrel of the unit 23 through a valve 90, to increase the total heat input into the material or increase the porosity of the elastomer. The extrusion press drier 22 comprises barrel bars 30, Fig. 3, held by split-ring retainers 31 and clamped by bolts 32 leaving slight spaces therebetween for the escape of liquid forced out by the action of screw flights on a shaft 35 and knife bar tips 34a projecting therebetween. The discharge end has an adjustable cone choke which can be advanced or retracted along the shaft to adjust the escape area between the cone and barrel which respectively carry movable and fixed cutter elements to co-operate in intermittent cutting engagement during rotation of the shaft.

Title: Improvements relating to a gauging apparatus for use with a frusto-conical article
IPC: G01B5/24
Filed: 1944-02-18
Abstract: 579,293. Linear-dimension gauges. BOWNESS, A. H. F. Feb. 18, 1944, No. 3041. [Class 106 (ii)] A gauge for measuring an axial dimension of a frustro-conical article, e.g. the height of the apex point above the thrust face of a bevel wheel, comprises a member slidable relatively to the article to be gauged, to which is pivoted a gauging arm which can be adjustably set relatively to the axis of the article at the correct angle of the article, and means for indicating the position of the slidable member when the arm is contacting the article under test. A pair of oppositely extending gauging arms may be provided instead of one, and their outer ends may be connected by links to an adjustable collar for setting the arms. The slidable member may be vertically slidable and means provided for counterbalancing the weight thereof and associated parts, or it may be slidable horizontally. The master article, e.g. bevel wheel 12, is placed on a horizontal V block 47 longitudinally adjustable in the slides 49. The support 14a carries a vertically slidable member 16 terminating in a pivot 17 for a pair of gauging arms 18, the gauging faces of the arms 18 being co-planar with the centre of pivot 17. The arms 18 are set to the bevel face 15, and held in position by links 20, adjustable collar 25 and locking bolt 26. The rod 41 is then adjusted and a zero reading arranged on the dial indicator 36, which is fixed in the support 14a. A work-piece is substituted for the master-piece, the slidable member 16, arms 18 with its associated parts lowered vertically until the gauging arms 18 engage the bevel face, and deviation from standard height indicated. The weight of sliding member 16 and associated parts may be' counterbalanced by a compression spring 34 acting on the lever 31 which bears against a pin 33 at one end and is articulated at 30 to the sliding member 16. The apparatus shown in Figs. 1 and 2 is unsuitable for use if the bevel wheel has a boss which could obstruct movement of the pivot 17. A modified apparatus is described to overcome this, in which one gauging arm is used and arranged so that the slidable member and associated parts are all on one side of the axis of the bevel wheel.
