Road signals; transparency and stencil luminous signals; semaphore and pointer signals. - In apparatus for signalling at cross-roads the approach of traffic, mechanism X, Fig. 12, placed level with the road surface, on the passage over it of a vehicle operates danger signals C, D and similar mechanism Z at the commencement of the crossway restores the signals to normal. The mechanism sunk in the roadway consists of a series of boxes such as B, Figs. 1 and 2. An operating lever O is keyed on a fulcrum shaft F, and to the lever is fixed an operating shaft 2 which is also supported by a lever O1 keyed on the shaft F. Cam levers F1, F6 rest on the operating shaft O2 and support a tripod T the legs of which terminate in rollers T2 and are provided with depending flanges T3 on each side of the levers F1 F6. A table L is supported level with the road surface by the tripod and by springs B5. The rollers T2 rest adjacent to inclined portions F2 on the cam levers so that even if the table L tilts under the weight of a vehicle the cam levers will be operated. Fulcrum brackets are fixed at the front and back of the table L so as to form inclined surfaces when the table is depressed. A wire rope 04 is attached to the end of the operating lever O. All the ropes 04 from one series of boxes are attached to a bar J12, Fig. 9, attached to one arm of a bell-crank lever J11 to the other arm of which is attached a single rope leading over pulleys to the signal mechanism. The signal mechanism consists of a pillar P, with arms C. D carried on spindles C1, D1, Figs. 5 and 6, the arm C being operated by traffic along the road M, Fig. 12, and the arm D by traffic along the crossroad S.

Abstract: 1,160,148. Sequence detection circuit. TELETYPE CORP. 14 Feb., 1967 [7 April, 1966], No. 7003/67. Heading G4H. To determine whether a plurality of signals arrive in a predetermined sequential order, correct receipt of the first signal (i.e. it arrives at terminal A, Fig. 1) sets a bi-stable element 10 to prime AND gates 31-33 so that if the succeeding signals arrive in the correct order, i.e. on terminals B, C, D, AND gates 31-33 are sequentially enabled (since ring counter 13 is stepped each time a signal is received) to set OR gate 24 to its "1" state, the output from which after inversion cannot then reset the bi-stable element 10. Each clock pulse applied to the counter 13 is also applied via a delay 21 and inverter 22 to the OR gate 24 so that each time a signal arrives the normal "1" input on lead 23 becomes zero and in the event of none of the AND gates 31-33 being enabled, OR gate 24 has a zero output which is inverted to reset the bi-stable element 10.

[Classes 83 (ii) and 83 (iv).] Welding ; uniting by fusion; working at specified temperatures.-Composite metal bodies, such as plates, rods or tubes, having a surface layer of corrosion-resistant metal such as an alloy of iron or steel with chromium or with chromium and nickel are made by uniting the surface layer to a base of mild steel through the intermediary of a thin sheet of comparatively pure iron. The intermediate sheet should have a low silicon and carbon content, preferably below 0À06 per cent of carbon. In making tubes the inner or outer layer may be of corrosionresistant metal. If both surfaces are to be of corrosion-resistant metal intermediate sheets of pure iron are applied to both surfaces of the base. The surfaces of the parts are smoothed by grinding or machining and then assembled and pressed together whilst the edges are welded by a rod and torch or by an electric arc. A gap is left in the edge, any trapped air removed by suction and the gap then sealed off. The parts are then heated to from 980 to 1230‹ C., preferably to about 1150‹ C. and then rolled or hammered to weld the layers together and to reduce the thickness of the slab. At the end of the rolling operation the temperature may be approximately 485‹ C. In one example the baseplate may be 2 cms. thick, the alloy sheet 3 mms. and the iron sheet about 1 mm. The composite plates may be used in the formation of digesters, autoclaves, storage tanks, household boilers, soak drums, &c. or tubes with seams welded by a rod or electrode of corrosion-resistant metal.
