Title: Improvements in electrical switch gear
IPC: H02B1/00
Filed: 1945-05-26
Abstract: 593,250. Switchgear structures; latching switches. BRUSH ELECTRICAL ENGINEERING CO., Ltd., and YELLAND, H. F. May 26, 1945, No. 13217. [Class 38(v)] A horizontally withdrawable stepdown transformer has the switches on its high and low-tension sides provided with locks and a common key such that the low-tension side must be opened before the key can be made available to unlock and open the high-tension side. The withdrawal of the transformer effects opening of the hightension side, but is prevented by the hightension lock until the low-tension side is opened. Further, each side is held in locked condition when the key is withdrawn therefrom, so the low-tension side cannot be closed until the high-tension side has, been closed. The arrangement avoids expansive switches on the high-tension side. The transformer 1 is mounted on a carriage 3 having rollers 4 running on rails 2 and is operated by a pair of toggles on each side, one link 14 being pivoted at 17 to rail 2 and the other 15 to the carriage 3 at 18. Contacts 32 provided with fuses 35 enter holes 34 in the h.t. cable-box 9 and engage spring contacts 31 therein, the holes being closed by shutters 37 which are pivoted at 39 and operated by the carriage 3, in its approach, by means of levers 40 and rods 42, 46. The toggles are interconnected by a tube 19 carrying a box 20 for the h.t. lock 21<1>, the latter comprising a pair of rods 28 slidable in the tube 19 and interconnected by a lever operated by the lock 21<1>. In the locking position these rods enter holes in the rails 2 and when they are unlocked and the key trapped, the rod 19 can be pulled to withdraw the transformer. In this position, movement of the key 22 to unlock 21<1> is prevented by springs on the lever 14 snapping into grooves in the rods to retain them in locked position, Fig. 5 (not shown). The shaft 23 of switch 11 has a cam 24 with a lobe 24b which, in the switch-closed position, obstructs a tongue 25 on the lock 21, the tongue 25 being only movable to allow unlocking and extraction of the key when a lobe 24a on cam 24 is opposite to it, namely, in the switch-open position.

IPC: A46B5/00
Abstract: 132,866. Edwards, J. T. Sept. 24, 1918. Rotary brushes; bristles, fixing; pads.- Rotary brushes for cleaning test-tubes, bottles, &c. have the bristles arranged side by side in rows longitudinally of the brush and projecting tangentially to a circle concentric with the axis of rotation. In the construction shown, the brush has a hollow core A made of two similar sheet - metal troughshaped parts a, a<1> formed with a longitudinal channel a<2> in which the bristles B, folded upon themselves about a fine wire b, are secured by pressing down the lip of the channel. The two parts a, a<1> are secured together by soldering. In a modification, a longitudinal groove is formed in the parts a, a', in which the doubled bristles are placed and secured by a strip of metal soldered thereto. A ring of bristles may be mounted at the end of the core so as to project obliquely to the axis. To obviate the risk of breaking testtubes &c., a cushioning pad C formed of rubber is secured by spring arms d to the end of the core. A spring e is inserted in a cavity in the pad so as to engage a washer f, and the pad may be formed with a number of small peripheral projections.

Title: Terminally reactive polymers
IPC: C08L63/00
Filed: 1962-04-06
Abstract: A terminally reactive polymer is prepared by polymerizing a vinylidene monomer in the presence of an organoalkali metal initiator and reacting the product with a polyaziridinyl compound so that the polymer has at least one terminally positioned aziridinyl group per polymer molecule.  Specified monomers are butadiene, isopene piperylene, 2-3-dimethylbutadiene, 3-methylpentadiene, 1-3-heptadiene, 3-butyl-octadiene, phenylbutadiene, chloroprene, fluoroprene, 2-methoxybutadiene, 2-ethoxy-3-ethylbutadiene, 2-ethoxy-3-methyl-hexadiene, styrene, vinyl naphthalenes, and their substitution products, vinyl pyridine and its derivatives, acrylates and methacrylates and their amides and nitriles.  The preferred metal initiator is an organolithium compound, e.g. 1-2-dilithio-12-diphenylethane while aziridinyl phosphinc oxide or sulphide are the preferred polyaziridinyl compounds.  The lithium atoms are replaced by hydrogen atoms e.g. by hydrolysis.  The product may be cured e.g. by treating or reacting with a mercapto substituted carboxy acid or acid anhydride.

Title: Improvements in or relating to the manufacture of electric fuzeheads such as are used, for example, in blasting detonators
IPC: F42B3/195
Filed: 1937-05-18
Abstract: 495,832. Electric fuzeheads; compound sheet materials. TAYLOR, W., HALL, C. R. L., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 18, 1937, No. 13904. [Class 9 (i)] [Also in Group VIII] A process for the manufacture of metalfoil-coated sheets or boards of insulating- material, suitable for use in the manufacture of low-tension electric fuzeheads for blasting- detonators, comprises preparing one face of a sheet of brass foil by an etching treatment and thereafter attaching the foil by its prepared surface to a sheet or board of insulating-material by means of a thermoplastic cement. The etching treatment consists in treating the foil with ammonia, preferably in aqueous solution, under oxidizing conditions until a black coating forms, treating the superficially-oxidized foil with an aqueous solution of ammonium chloride or like acidic salt, or with a concentrated aqueous solution of a caustic alkali preferably at raised temperature, until the superficial coating is completely converted into a loosely adherent deposit and thereafter removing the deposit by washing, with or without abrasion, and drying the etched foil. In carrying out this treatment, two strips of brass foil may be placed in contact and rolled up in a spiral with a reticulated spacer adapted to maintain the sheets of foil in contact on the inner surfaces and thus substantially to prevent the access of liquid to the juxtaposed surfaces while permitting the access of the liquids to the exposed surfaces. If desired, the treatment with the discharging salt solution may be carried out in two stages with an intermediate washing. The thermoplastic cement may be applied to the etched surfaces by means of a volatile solvent and the cemented faces of the foil are then brought into contact with the pressboard sheet and caused to adhere thereto by the application of pressure at a raised temperature. If it is desired to coil up and store the coated foil, a thermoplastic cement of such a nature that the coating is not tacky at room temperature is employed, e.g. a solution of polyvinyl acetate in a volatile organic solvent such as a mixture of benzene and alcohol. The cement may, however, be applied to the presssboard instead of to the etched metal surfaces. In the manufacture of low tension electric fuzeheads, combs are stamped out from the composite sheet and the metal coating on one side at the tips of the combs and the insulating layer immediately underneath may be milled away as described in Specification 495,833 so as to provide steps for the bridge wire of each tooth.
