[Class 37] [Also in Group XXXVII] A chain of insulators supporting an overhead conductor is tested, when the supply is disconnected, by hoisting a framework into the position shown, when parts thereof connect the individual insulators in parallel across an impulse generator. The framework comprises insulating tubes V<1>, V<2> rigidly connected by metal bars H, and springs r connected alternately to the high tension test wire in the tube V<2> and an earthed wire in tube V<1>, the bars H and springs r being so spaced as to contact with the caps of successive insulators. The test wire is bare except where insulated at F, wound about a drum O and connected through a switch I to the secondary of an induction coil B the terminal T of which is earthed. The primary circuit is controlled by a mechanical contact breaker R actuated, for example, by a handle and provided with a device for locking it in the open position. A discharge gap E is set to discharge at, for example, 90 per cent of the breakdown voltage of an individual insulator and during a test absence of sparks across E indicates that a leakage current is passing through one or more of the insulators. The interrupter R may be replaced by a mercury switch M, Fig. 2, mounted on a free or automatically maintained pendulum P normally held in the open circuit position of switch M, shown, by a lever D biassed by a spring R. The lever D and a contact S form a further safety switch in series with M to prevent closure of the circuit until the lever is raised.

Abstract: 386,516. Roads and ways. PARRACK, H. O., 1, Vale Road, Forest Gate, London. May 19, 1932, No. 14214. Drawings to Specification. [Classes 20 (iv) and 107.] A process of constructing paving consists in spreading and consolidating a layer of broken stones, forcing a grouting of cement into the same in a quantity and manner adapted to ensure penetration of the grouting into all the interstices between the broken stones and a surplus of grouting to accumulate upon the surface of the layer, and working a layer of broken stones of smaller size into the surplus .grouting before the latter has set so that portions of the stones of the second layer are forced into the interstices between the uppermost stones of the first layer. Portions of the stones of the second layer may be left projecting above the surface of the grouting so as to serve as keys for a surface layer of bitumen or the like which is applied after the grouting has set. Alternatively, the upper surface of the second layer may be rolled until it is level with the surface of the grouting, and a wearing coat of bitumen or the like may be applied before the grouting has set. If desired, after the second layer of stones has been rolled, one or more further layers of stone of progressively decreasing sizes may be rolled into the surplus grouting which was extruded during rolling of the previous layer.
Patent GB-142868-A (GB)
Abstract: 142,868. Schmid, H., and Fuegel, G. July 18, 1917, [Convention date]. Rotary interrupters for use in the ignition of internal-combustion engines have the interrupter lever carried by springs, a further spring continually resisting deflexion of the lever from its closed contact position. The lever is moved by internal cams 10 the deviating surfaces 12 of which are concave joined by other concave parts, so that a smooth rubbing surface is provided for the fibre bumper 9 throughout its rotation. The cam-ring is screwed to a casing 11 which is slipped over an annular projection 18, Fig. 1, of a cover-plate 16 for the magneto armature, the casing 11 has ears 29 by which it is turned for timing, a screw 48 limiting the movement. The interrupter contacts are mounted on the plate 2 rotating with the magneto armature, the fixed adjustable contact 3 being connected to the insulated holding-bolt 19, and the moving contact being carried by the rocker 6. This is attached by two pairs of springs 8, Fig. 4, to a projection 7 on the plate 2; the rocker is channel-shaped, the inner of the upper pair of springs 8 passing to the end of the rocker, and the contact 5 screwing through a small block, the spring, and the rocker. The outer spring of this pair may have a fibre pad between its end and where it bears on the rocker. The end of the rocker remote from the contact 5 is heavy, so that the effect of centrifugal force tends to keep the contacts closed. If for use with a dual ignition system, the battery interrupted consists of a contact carrying lever 30 pivoted at 31 to the casing 11, its fibre bumper 9<a> bearing on the smooth exterior of the plate 2, which is then formed with suitable cam-surfaces. A casing 45 covers this interrupter, an inspection opening closed by a screw being provided opposite the contacts. The usual short-circuiting terminal 50 is carried by the spring-held cover-plate 26. When for use with an eight or twelve cylinder engine, two of the internal cam-rings and associated interrupter contacts are mounted side by side in the casing 11 and connected in parallel, the cams being relatively disposed to open and close one pair of contacts in turn. The two sets of interrupter contacts &c. can be used for a. four-cylinder engine, one set working if the other fouls. The interrupter may be readily adjusted for either direction of running by reversing the position of the cams and contacts.
