Title: Improvements in railway motor wagons
IPC: B61C5/00
Filed: 1933-11-27
Abstract: 429,193. Motor-vehicle driving-gear. CONSTANTINESCO, G., Oxen House, Torver, Coniston, Lancashire. Nov. 27, 1933, No. 33196. [Classes 79 (ii) and 79 (iii)] A rail or road vehicle is provided with an auxiliary axle or shaft 7 carrying one or more wheels 8 provided with rubber or like tyres adapted to be forced into contact with drums 15 attached to the supporting wheels 3 of the vehicle, automatic means governed by the slip of the wheels being provided for varying the pressure between the wheels 8 and the drums 15 to suit varying conditions of grip and load in such a manner that the drive occurs always with approximately the minimum of pressure between the surfaces in contact. In the construction shown, the auxiliary axle 7 is mounted on a power unit 6 pivoted at 4 to the vehicle frame 1 and controlled by a fluid pressure cylinder 13. The automatic control may be that described in Specification 415,808 in which relative slip between the surfaces in contact is used to control devices to vary the pressure between the surfaces. Two parallel auxiliary shafts may be employed, one on each side of a vehicle axle, so that each drum on the axle is engaged by a wheel on each auxiliary shaft. In this construction the power unit is suspended by links and end movement is limited by stops. The auxiliary wheels may be connected by a belt which makes contact with the drum on the axle. In another modification, a single auxiliary wheel may engage a belt connecting two drums on adjacent axles. The cylinder 13 is preferably operated by compressed air and may be double acting so that the auxiliary wheels 8 may be completely disengaged from the drums 15 when desired. The drums may be cleaned by wipers or dried by a blast of exhaust gases, compressed air or flame directed on the contacting surface. According to the Provisional Specification one rubber tyred auxiliary wheel may be in contact with two drums, one on each of two supporting axles.

Title: An improved method of and means for measuring, indicating or recording the efficiency of an electric generating station or the component parts thereof
IPC: G01R1/30
Filed: 1921-12-10
Abstract: 196,019. Gilson, P. C., and Dubilier Condenser Co. (1921), Ltd. Dec. 10, 1921. Indicating rate of generation of steam.-The efficiency of an electric generating station, or of its component parts, is measured, indicated, or recorded by employing two electric circuits, the current in one circuit being always directly proportional to one of the quantities to be measured, and the current in the other quantity, the ratio of these two currents being determined by a wattmeter or like multiplying device. In one arrangement, shown in Fig. 1, two wattmeters W, W<1> have their fixed coils X, X<1> connected in series with the secondary winding S of a current transformer through which a current directly proportional to the electrical load flows, and the moving-coils Y, Y<1> are connected in coal and water circuits joined in parallel and supplied from the secondary winding of a potential transformer T. The stoker circuits M - - -Q are each provided with resistances A - - D having different values per unit length corresponding with the grate speeds. The water or steam circuit is also provided with a variable resistance H, all the resistances being varied directly proportional to the amount of coal &c. consumed so that the currents in the moving-coils of wattmeters are inversely proportional to the consumption, and the reading will therefore indicate &c. the amount of coal &c. consumed per electrical unit generated at all power factors. The contact sliders F are operated by the fire-door gear so that the resistances A - - D vary directly with the thickness of fire. The switches E are operated by the stoker speed gear and engage, contacts 1 - 4 according to the speed. When the stoker gear is inoperative the switch engages contact 5 thus short-circuiting the resistances, and this may be. done automatically. In another arrangement, shown in Fig. 2, the switches E are linear operated, and the firedoor slides F engages three resistances A<1> - - C<1>. The stoker-speed gear engages four contacts 11 - - 14, 12 and 13 being continuous and always engaged by the switches E<1>. Contact 11 is divided into parts 11<a>, 11<b> connected respectively to the resistance C', and the slider F. Contact 14 is divided into five parts 14<a> - - 14e, two being connected to each of the resistances A<1>, B<1> and one to the contact 12. Four stoker speeds are thus provided for and when any stoker is inoperative the resistances are short-circuited. The boilerhouse efficiency may be indicated &c. by connecting the coal circuit to one wattmeter coil and the water circuit to the other, one of the currents being made directly proportional to the particular quantity consumed. When more than one current transforrner is employed the wattmeter fixed coil may be subdivided.

IPC: B29C48/10
Filed: 1963-08-23
Abstract: 1,042,182. Paper; bonded-fibre fabrics. UNION CARBIDE CORPORATION. Aug. 23, 1963, No. 33383/63. Headings D1R and D2B. [Also in Divisions A2 and B5] Reinforced cellulosic sausage casings are made from a dispersion in viscose from 0.1 to 10% by weight of the cellulose in the viscose of at least one dimer of a ketene having the formula where R is an alkyl or an alkenyl radical containing 12 to 22 carbon atoms, annularly extruding the ketene dimer-containing viscose composition on to a fibrous reinforcement to form continuous tubing and regenerating the cellulose in said tubing. Specified ketene dimers include dodecyl, tetradecyl, hexedecyl, nondecyl, eicosyl, docosyl 7-hexadecenyl, 7-dodecenyl and eicosenyl ketene dimers, a mixture of tetradecyl and hexadecyl being preferred. Liquid ketene dimers may be mixed as such or as aqueous emulsions with the viscose. Solid ketene dimers are preferably added to the viscose as an aqueous emulsion, the emulsion containing conventional emulsifying agents, e.g. ethylene oxide derivatives of the partial esters of polyhydric alcohols such as glycerine, and sorbitan, e.g. polyoxyethylene derivatives of sorbiton monolaurate; soaps; and partial esters of polyhydric alcohols e.g. sorbitan monopalmitate. The fibrous reinforcement may be hemp fibre paper, yoshino paper, rice paper, nonwoven webs of nylon or polyethylene, or woven fabrics of muslin, cheese cloth, marquisette, organdie and foile of synthetic fibres e.g. nylon, or of natural fibres e.g. cotton, or flax. In Fig. 1, a porous fibrous web 10, e.g. of paper is fed over the roll, folded to form a tube 12, and passed through the forming ring 14 and leaves at mandrel 12 through the viscose extrusion means 16, supplied with the ketene dimer containing viscose from 20. The viscose flows from chamber 18 to annular orifice 19 and hence impregnates the paper tubing. The tubing is then passed through conventional coagulating and regenerating baths to regenerate the cellulose, the tubing washed, plasticized, and dried. In the apparatus of Fig. 2, the tubing is impregnated with ketene dimer containing viscose from tube 34 and then overlay coated with conventional viscose from tube 26. Coagulation and regeneration are effected as before. In the apparatus of Fig. 3 (not reproduced) ketene dimer containing viscose from 44 is applied to the interior surface of the tube, coagulation and regeneration being effected as before.

Filed: 1970-07-10
Abstract: 1313951 Data processing INTERNATIONAL BUSINESS MACHINES CORP 10 July 1970 [11 July 1969] 33505/70 Heading G4A A data processing system includes a CPU having a working store divided into a plurality of multi-register zones for storing data relating to programmes of respective different priority levels, one of the zones being selected by means including a first register for storing a zone address and a second register for storing a plurality of programme request signals from peripheral units, the first register being set in accordance with the highest priority level programme requested, in response to the second register, and register selection means common to all the zones is operable to apply a selection signal simultaneously to corresponding registers in each zone. Request signals from the peripheral units depend on the type of the peripheral unit and the reason for the request, and, via OR gates in some cases, set latches in the second register, a priority network, Fig. 5 (not shown), indicating the highest priority request on one of 7 lines, or if there is no request, indicating the current problem programme on an eighth line. If the output of the priority network differs from the contents of the first register, the latter is set with the network output to select a zone in the working store holding instruction count, accumulator, addresses, data, word length indicators, indexing constants, &c. for the programme required, the programmes themselves and data being in a main store. Interruption of a programme for a programme of lower priority is prevented by the second register maintaining the request for the former at the priority network. The output of the priority network can also be gated to select a zone directly, this permitting execution of successive instructions to be overlapped. Where a given programme request could have come from one of several peripheral units or for one of several reasons, the programme scans bistable indicators at the peripheral units to identify which and branch accordingly.

Title: Improvements in and relating to pile thread holders for looms for weaving pile carpets
IPC: D03D39/02
Filed: 1920-11-27
Abstract: 154,594. Boyer, F. Nov. 29, 1919, [Convention date]. Pile-fabric looms; vertical looms.-A pile-thread holder for looms for weaving pile carpets is provided with a clamp which seizes the pile thread when it is introduced into the warps and holds it fast until the formation of the knot is completed and thereby supports the warps independently of the knotting-tools proper, so that their lateral divergence is prevented. Pile thread 2, Fig. 17, is guided by a thread-guide 3 into grippers 4, 5 which close and grip the thread. The guide 3 moves upwards, carrier pins 6 move towards the warps 1, and the guide moves to cause the thread to be at an angle to the pins. Hooks 7, movable in guides 8, then move between the warps and seize the ends of the pile thread, two warps being between each pair of hooks 7. The guide 3 moves away, the pile thread is severed by a knife 11, and the grippers 4, 5 are released. When the hooks 7, clamping the pile thread against the guides 8, return to draw it through the warps, slotted beakshaped pile-thread holders 31 advance towards the warps and a clamping-bar 36 having slotted clamping-pins 40 is raised, so that the pile threads enter between the parts 31, 40, Fig. 19, and are clamped therein, each clamping-pin 40 and the corresponding holder 31 being situated midway between the two hooks. The hooks 7 with their guides 8 then move laterally and a hook 9 movable in a guide 10 advances between the warps, seizes one end of the pile thread, and retires. The hooks 7 then move laterally in the opposite direction and the hook 9 is again advanced and seizes the other end of the pile thread. The hook 9 then clamps both ends of the pile thread against the guide 10 and draws them through the warps to form a knot as shown in Fig. 12. The clamping-bar then rises to release the pile thread, the hook 9 tightens the knotted pile thread and releases its ends. Reference has been directed by the Comptroller to Specification 15548/00.

[Also in Divisions B5 and C3] In a method for preparing a moisture permeable artificial leather a polymer solution containing finely divided solid material, which is substantially insoluble in the polymer solution and is of particle size 0.1 micron to 300 microns, is coated onto a web of woven, knitted, or non-woven fabric or fleece, and the coated web or fleece is soaked in a liquid which is a non-solvent for the polymer and its supporting base, but which is miscible with the polymer solvent, to coagulate and precipitate the polymer, after which the coated material is washed, and then dried by passing through squeeze rollers on subjecting the coated base material to a known coating finish, and buffing the uncoated side of the base material a pliant artificial leather is obtained. The solid material is desirably present in the polymer solution in amounts between 5 and 70% by weight. Solid materials specified are precipitated calcium carbonate, magnesium carbonate, iron oxides, titanium oxide, milled pulp and cellulose crystallite. Solvents which may be used include acetone, tetrahydrofuran, acetonitrile, N,N-dimethylformamide, N,N- dimethylacetamide, N,N-diethylformamide, tetramethylurea, dimethylsulphoxide, methanol, formic acid and m-cresol. Coagulating liquids specified are water, ethylene glycol, glycerol, methanol and ethanol. The preferred polymer is a reaction product of an essentially bifunctional compound containing terminal primary amino groups, suitable compounds being for example, hydrazine, hydrazine hydrate, ethylene diamine, 1,2-propylene diamine, tetramethylene diamine, and m-xylylene diamine, with an essentially bifunctional polyalkylene ether, polyacetal, or polyester, containing terminal functional groups selected from isocyanate, acyl halogenide, carbamyl halogenide, and urea groups. Other polymers which may be used are nylon, polyester, acrylonitrile oopolymers and polyvinyl chloride. The solid material may be in the form of spheres, ellipsoids, needles, columns, a combination of these, or may be agglomerated into secondary particles. In an example a solution of a mixture of polypropylene ether polyurea elastomer and polyvinyl chloride in N,N-dimethylformamide, the solution containing precipitated calcium carbonate, was applied to cotton flannel impregnated with a 12% N,N-dimethylformamide solution of the polyurea elastomer above, and the polymer was then coagulated in water.
