Title: Road vehicle detector
IPC: G08G1/02
Filed: 1957-03-04
Abstract: 859,049. Road traffic detectors. EASTERN INDUSTRIES Inc. March 4, 1957 [March 5, 1956], No. 7145/57. Class 118 (2). A multi-contact road pad comprises an elongated base 5 extending across the traffic lane perpendicular to it, and a number of elongated contacts 3, 4 supported on the base in side-by-side relation and arranged at a slight angle (e.g. 1 inch in 8 feet) with respect to the longitudinal axis of the base to provide overlapping actuation of the successive switch contacts by a pair of transversely spaced wheels 8, 9 of an axle. The unit is covered by a watertight resilient casing 1. For a vehicle moving in the direction shown in Fig. 3, contact 3 closes to energize relay IF which in turn energizes relay 2F. As the vehicle moves on, contact 4 closes energizing relay IR which provides a hold circuit for relay 2F. Further movement opens contact 3 releasing relay IF, relay 2F remaining energized over the contacts of relay 1R. Relay 3F is energized over contacts 2F2 and 1F3 and completes a self-holding circuit over contact 3F1. When the vehicle moves clear of the pad, relays 1R, 2F release and a " forward counter " FC operates, this releases relay 3F, and the equipment restores to normal. Passage of a vehicle in the reverse direction operates a " reverse counter " RC, by a similar sequence of events.

Title: Improvements in and relating to furnaces
IPC: F23H11/00
Filed: 1926-03-16
Abstract: 277,396. Ljungstr÷m, B. March 16, 1926. Steam boiler &c. furnaces; grates; firebridges; fuel, feeding.-A method of burning fuel in furnaces consists in delivering the fuel at one or more points of a fuel supporting surface and conveying it through the furnace with, if desired, a portion of the fuel residues, in a closed circuit, unburnt fuel and fuel residues which are not discharged from the furnace serving to ignite the fresh fuel and protect the fuel-supporting surfaces. Incombustible substances such as sand may be delivered to the fuel supporting surfaces to supplement the fuel residues or ash. Figs. 1 and 2 show a furnace in which the fuel is burnt as stated above. It comprises a travelling grate, sections 3 of which are supplied with fuel from a hopper 5 and carry it towards the rear of the furnace where it is deflected by the inclined sur. face of a bridge 18 on to forwardly moving grate sections 6. Adjustable flaps 21 on a shaft 22 cause a part of the ash to be deflected from the sections on to the sections 3 and to be recirculated through the furnace. A portion of the ash passes beneath the flaps to the ash-pit from which it is removed by conveyers 27, 28. The shaft 22 also carries loosely mounted flaps 20 resting by gravity on the sections 6. The grate sections 3 and 6 are driven in opposite directions by toothed discs 23, 24 mounted on shafts 25, 26 and adapted to be driven by suitable gearing. Partitions 7, 8 between the grate sections extend upwardly above the flued surfaces and serve to separate the forwardly and rearwardly moving fuel. A free communication between the travelling beds of fuel is however provided at the ends of the partitions. The bridge 18 and the flaps 21 may be provided with wedge-shape deflecting surfaces to facilitate the passage of the fuel and ash from one grate section to the adjacent one. The bridge 18 may be reciprocated laterally. In the modification shown in Fig. 9, fuel and non- combustible material are supplied to the section 3 of the grate through separate pipes 4 and the fuel is returned on two lateral sections 6. Various modifications are described in which the circuitous paths of the fuel and fuel residues vary. In other modifications the grate sections 3 and 6 are arranged at different levels throughout their length or at or between their ends. Instead of the partitions 7, 8, air or water-cooled partitions 42, Fig. 22 or water-cooled refractory partitions 43, Fig. 24, may be employed dividing the furnace into separate combustion chambers having grates moving in opposite directions. A modification is shown in Fig. 7 in which the fuel is conveyed through the furnace by screw conveyers, the fuel being conveyed rearwardly by the intermediate pair of screws and returned by the two outer pairs.

Filed: 1958-03-11
Abstract: 840,488. Blow-moulding hollow articles. S.A.S. LAVORAZIONE MATERIE PLASTICHE (L.M.P.) DI M. I. COLOMBO & C. March 11, 1958 [March 16, 1957], No. 77955/68. Class 87(2). Apparatus for blow-moulding hollow articles from e.g. polyethylene or polyamide, comprises a nozzle 26 to deliver a lump 60 at softened material into a transfer chamber 21, a sectional mould 40 supported under the chamber 21 for movement with the chamber in respect to the nozzle 26, a piston 34 having a needle 38 adapted to enter the chamber 21, penetrate the lump 60 and expel it towards the mould 40, means 44 for closing the mould onto the lump 60 and means for delivering fluid to the needle 38 to expand the lump into contact with the mould 40. The nozzle 26 extrudes the lump 60 into one of a number of chambers 21 provided in a rotatable table 14. Rotation of the table stops the extrusion, moves the chamber 21 clear of the nozzle 26 and allows extrusion to commence in the next chamber 21. A double acting piston 31, in a cylinder 30 fixed to the table above the chamber 21, then moves downwards until its stem 32 abuts the top of the chamber 21. The piston 34 with a stem 36 and the hollow needle 38 then moves downwards, in the cylinder 33 of the stem 32, until the needle 38 enters the lump 60 and continued movement of the stem 36 through the chamber 21 causes the slug 60, impaled on the needle 38, to move downwards out of the chamber 21 and to be suspended between the open two-part mould 40. Closing of the mould 40 compression moulds the neck of the articles and air admitted through the needle 38 expands the slug 60 into contact with the mould. The needle is then withdrawn and the mould opened to discharge the article. After the withdrawal of the needle and before the mould opening a knife may trim the top of the neck of the article protruding above the mould.
