Title: Improvements in Continuous Cab Signalling System for Railways.
Inventor: STARIE BERNARD
IPC: B61L3/22
Filed: 1917-02-07
Abstract: 110,148. Starie, B. Sept. 30, 1916, [Convention date]. T r a c k apparatus actuating signals on trains and for stopping trains.-Apparatus on a train is controlled, according to the condition of the track ahead, by an alternating current produced on the train, the magnitude of which is varied by opening and closing one or more track branch - loop circuits, thus producing maximum or minimum current m the main circuit on the locomotive. The train carries a generator of high-frequency oscillating current in a circuit which includes a condenser 11 and a responsive device, as a thermo-junction heating-element 23, and is completed through the frame and the front and rear axles 12, 13 of the locomotive. The rail 14 between these axles forms one branch circuit, having a considerable impedance. A second branch circuit includes the rails in front and rear of the locomotive as far as points 19, 20 at which is connected a conductor 28, including a switch controlled by the signal 30 and a condenser 16, which is adjusted so as to neutralize the inductive reactance of this loop. When the contact on the signal is closed, the current in the main circuit is larger than when this is open. The shorter loop circuit 29 is provided to produce a still greater current on the train so as to cause the re-setting of the valve 26 and to give location signals. Adjacent sections utilize opposite track rails and overlap to the extent of the loops 29.

Title: Method for making an electron-tube grid assembly
IPC: H01J9/14
Filed: 1971-01-15
Abstract: 1329682 Making valve grids RCA CORPORATION 15 Jan 1971 [16 Jan 1970] 2091/71 Headings B3A and B3V [Also in Division H1] A method of making a valve grid assembly comprises machining by electrical discharge a number of apertures in a plurality of grid blanks, one being disposed outside the next, whose spacing corresponds with that in the completed valve, and removing machining particles by a flow of dielectric fluid at least in the region of the cutting. A control grid 12 and screen grid 13, Fig. 4, are assembled with ceramic rings 29, 30 and two such assemblies are loaded in a pair of chucks 42, which are coupled by gears 63, 63. The grid blanks are centred by a spring loaded tapered disc 59 and are located with their axes horizontal in a tank (38), which is then filled with dielectric fluid, Fig. 3 (not shown). Electrodes (36) are lowered to form a set of radially aligned apertures in each grid blank assembly, a contact rod 79, Fig. 7, following the movement of the electrodes. At the end of the cutting stroke a switch 82 grounds the electrodes and causes them to be retracted. Retraction of the electrodes operates a switch 93 thereby actuating a pneumatic cylinder (73), Fig. 5 (not shown), to index the grid blanks by a lever mechanism engaging a gear 64, and actuating a pneumatic cylinder 91 to rotate a lead screw 86. The lead screw lowers a block 84 on which is mounted a switch actuator 83, thereby lowering the cutting stroke of the electrodes to compensate for wear and operating the switch 82 to start a further cutting cycle. The dielectric fluid is pumped in through a hole 53 and nozzle 52 flowing out through openings 101, 102, Fig. 8. Openings 96, 97 in the tapered portions of the grids 12, 13 allow the fluid to pass between them and to flow past the electrode 36. Alternatively a cylindrical end cap may be fitted, the cap having only one opening which accomodates the electrode. By this means all the fluid is forced to flow past the cutting region.
Patent GB-802153-A (GB)
Title: Resinous products
IPC: C08G18/64
Filed: 1955-01-24
Abstract: Resinous products suitable for coating and sealing purposes are prepared by reacting a diisocyanate or diisothiocyanate with a diol, reacting the product with water and with a bifunctional carboxylic acid or a liquid polyester to form an intermediate polymer and finally cross-linking the intermediate polymer with a compound containing at least three groups reactive with the isocyanate radical.  The molar quantity of diisocyanate is in excess of the sum of the molar quantities of all the other reactants used in making the intermediate polymer.  The products air cure in thin sections.  The products may be mixed with a polysulphides polymer and the curing of the resulting composition assisted by a mixed catalyst system.  The polyesters employed are preferably derived at least in part from 1-3 butylene glycol and sebacic acid and have acid numbers from 20 to 150.  Ten examples of suitable polyesters are given.  The diol employed is preferably a mixture of a low molecular weight glycol with a polyglycol of molecular weight 400-10,000.  The bifunctional acid may be a dicarboxylic acid, a hydroxy acid or an amino-acid. The cross-linking agent may contain hydroxy, carboxy, amino or mercaptan groups as groups reactive with the isocyanate radical. Fourteen examples are given of intermediate polymers using a bifunctional acid in the formulation and eleven of intermediate polymers using polyester resins.  Time and temperature charts are given for the production of the two types of product (including the introduction of the cross-linking agent).  The products may be compounded with the usual additives such as solvents (ketones, esters, ethers and halogenated hydrocarbons), fillers and pigments (talc, mica, asbestos, rayon flock, graphite, carbon black, iron oxide, chromates, silica, chromium powder, organic pigments), plasticisers (dioctyl phthalate, polyglycol diesters, dibutyl sebacate, tricresylphosphate, esteramides, silicones, di-2-ethyl hexyl adipate, chlorinated diphenyl).  The polysulphide resins which may be used in admixture with the diisocyanate polymers have molecular weights from 500-4000 and a low degree of cross-linking.  The catalyst mixture for the compositions containing a polysulphide resin preferably include an amine (including hydrazine) for the diisocyanate polymer and a peroxide for the polysulphide.  The polysulphide catalyst may be zinc, cadmium or mercury oxide.  Accelerators such as other amines, metal soaps, metal dimers or quinone dioxime may be included. Sixteen examples of compositions containing polysulphide resins are given with the polysulphide comprising up to about 85 per cent by weight of the composition.  Uses.-As films formed by the usual techniques; as coatings and impregnants applied by the usual techniques to metal, wood, cloth, glass, paper or plastics, e.g. acrylic or styrene plastics; in combination with polysulphide resins as sealing and caulking materials, gaskets for oil and grease and as window glazing material.

[Also in Group VI] Aqueous suspensions of yeast, mould mycelium, algae, &c. to which an osmotically active compound has been added to cause exudation of the intracellular water from the cells, are continuously washed and dried by suction filtration, preferably using a rotary drum vacuum filter, Fig. 1, consisting of a double-walled drum 1, the outer wall of which is perforated and covered by a filter cloth 2. The drum rotates on hollow spokes 4 communicating with the vacuum pump 5. Yeast, &c. suspension containing the osmotically active material e.g. sodium chloride, is delivered to the trough 7 through pipe 8 and is taken up as a layer 11 on the filter drum 1, section A. In passing the stripper 9 the drying layer is sprayed by a predetermined amount of liquid, especially water, of lower osmotic pressure from nozzles 12, 13, section B, to displace the osmotically active suspension. In section C most of the liquid is removed from the layer by the suction produced or absorbed into the cells, as intracellular water, the amount of extracellular water in the product removed by the scraper blade 10 being very small. Solids contents of 29-37À5 per cent are obtainable accompanied by a marked decrease in plasticity on account of the reduction in extracellular water. It is essential that the time allowed for re-absorption is less than that for complete re-absorption of intra- and extra-cellular water. An example of working conditions and apparatus is given in the Specification.
