Abstract: 1407549 Radar traffic surveillance THOMSON-CSF 5 July 1973 [7 July 1972] 32176/73 Heading H4D In a radar surveillance system for the detection of fixed or moving objects 4, Fig. 1, on a route 3, two leaky lines 1, 2 are laid parallel along the route, mutually isolated from one another and respectively connected to a receiver 12 and a pulse transmitter 22. The lines are terminated in their characteristic impedances 11, 21. Due to the mutually isolation of the lines, impedance discontinuities in the transmitting leaky line 3 will not produce a response in the receiving line 1, said receiving line only receiving a signal from the transmitting line by means of a reflection from the object 4. The echo signals are utilized or displayed at 13. The receiver 12 and terminating impedance may be transposed, Fig. 2, so that a pulse from transmitter 22 travels along line 2, is reflected from object 4 and travels along line 1 to the receiver 12. To enable the position of the object 4 to be determined, the receiving line 1 has a different (e.g. ¢) propagation velocity from that of the transmitting line 2. The lines may be twin (Fig. 3, not shown) or single (Fig. 4, not shown) conductor cables, imbedded in insulation and mutually isolated by a metal upright wall extending from a metal horizontal support.

Filed: 1936-12-03
Abstract: 474,117. Moulding fuel blocks by endless-chain machines. FULOP, J. Dec. 3, 1936, No. 33221. Convention date, Dec. 3, 1935. [Class 87 (ii)] [Also in Group XII] Metal moulds used in coking coal are discharged one by one from a stack on a rising lift and pass behind one another along a horizontal path where they are emptied, refilled with powdered coal and replaced in a stack on a descending lift moving at the same speed as the first lift. The moulds comprise vertical walls 1 open at the top and bottom and having internal partitions 2. Further removable partitions B are supported on projections 3 and a bottom plate H is pivoted on pins 11 in projections 7 on the side walls. Various shaped blocks may be produced, some of which are adapted to be bound in bundles. The moulds are stacked on a support comprising two platforms L each having two wheels 17 and connected together by male and female buffers 18, 19. The axle shafts have hollow ends filled with lubricant. The stack of moulds is brought from the coking oven by a conveyer 23 and is wheeled on to a lift N operated by racks 24. The two lifts N, O are operated simultaneously but in opposite directions from a common driving shaft 26 by means of pinions 28, 29 and 36, 36a which drive shaft 30 and consequently shafts 34 in one or other direction. The reverse movement operates at higher speed owing to gearing 38. The moulds are removed one by one from the top of the stack by endless chains S which are operated intermittently from the main shaft 26 by a mutilated gear 46. The moulds are carried above a discharge space 42 where the bottoms H swing down and the shaped blocks are ejected by a pusher V driven intermittently from the gear 46. The blocks fall on to a conveyer 43 and are sprinkled by a water jet 67. The bottoms Hare closed again by the inclined wall 44. The moulds are then carried beneath a telescopic filling hopper U and during filling the moulds are vibrated by eccentric wheels K. In order that the top mould of a stack may be left empty to form a lid, a plate 61 is provided for closing the hopper U, the plate being operated at the appropriate moment by teeth 65 on the chains S engaging pinions 63A. As a safety device the two lifts are connected by a chain 39 which carries a double rack 69 engaged alternately by teeth 76 of a ratchet 73 reciprocated by a rack-andpinion drive 75. In a modification, the bottoms H are separate from the moulds and at the discharge space are engaged by a bell-crank lever arm which pivots downwards to open them. The plates H may also slide horizontally in grooves in the mould.
