Title: Traffic monitoring system
IPC: G08G1/054
Filed: 1971-06-23
Abstract: 1362235 Road traffic measurements LTV AEROSPACE CORP 23 June 1971 [23 June 1970] 29525/71 Heading G4Q A traffic monitoring system incorporating a camera for photographing a vehicle violating a minimum or maximum speed limit, is provided with a tracking system, comprising a movable mirror, for projecting a substantially stationary image of the vehicle into the camera. In one embodiment (Fig. 1) for monitoring a single traffic lane, a pair of longitudinally spaced sensors 20, 21 are employed. Logic circuitry is such that only pulses generated by passage of front wheels of a vehicle 22 over the sensors 20, 21 are utilized in computing the vehicle speed. A speed computing means 38 produces an output signal directly representative of vehicle speed. Should the speed constitute a limit violation, a picture-taking decision means39 is energized and produces an output which is supplied to a camera-operating solenoid 43 to cause operation of camera 44; and is supplied to camera mirror tracking means 40 which is constructed to respond to the computed speed of the vehicle to optically track the vehicle. The rate of pivoting of the mirror is in accordance with the vehicle speed. The component of vehicle speed normal to the line of sight 49 of the mirror will cause some blurring of the photograph; this can be compensated by use of a fast camera and film and proper lighting, or by use of a more precise tracking means (Figs. 14, 15, not shown). Where a vehicle is moving so slowly that, after its front wheels have passed over the start sensor 20, the time-delay incorporated (equivalent to the distance between the sensors 20, 21 at a given higher speed) expires while the vehicle still straddles the start sensor 20, a detecting logic (Fig. 6, not shown) prevents a false computation which would result from the start sensor 20 being activated again by the rear wheels.  In another embodiment (Figs. 7 and 8) for monitoring a number of traffic lanes, each lane has a pair of sensors, but the lanes use a common camera 296 and mirror 295. Also provided is an anti-contention circuit which functions to prevent vehicles in other lanes from actuating the speed-computation means and camera after these have been actuated by another vehicle in a given lane.

Title: Improvements in or relating to the manufacture of elastic rubber thread, cord, stripand the like
IPC: B29D99/00
Filed: 1932-10-22
Abstract: 407,763. Rubber threads and tapes. SOC. ITALIANA PIRELLI, and PESTALOZZA, U., 21, Via Fabio Filzi, Milan, Italy. Oct. 22, 1932, No. 29616. Convention date, June 4. [Class 70.] Rubber thread, cord, or small tube, is made by forming a parent length of unvulcanized rubber or of vulcanized latex coagulum containing a substantial proportion of the water of the dispersion, having a crosssectional form corresponding to that required in the final thread &c., drawing this length out, and setting it permanently in this form, with subsequent vulcanization, if necessary. Stretching may proceed by stages with intervening periods of rest. Permanency is obtained by heating during stretching or in the rest periods. A thick thread &c. 2 is passed once round a roll 1, and is stretched by being drawn on to a roll 5 driven at a higher speed. From roll 5 it passes to a drum 6 rotated at the same peripheral speed, and heated, e.g. by immersion in a bath 7, or internally by steam. The set thread passes to a roll 8, and is submitted to a second stage of stretching and setting on roll 9, and drum 10. It may pass through a third stage, or be batched on a roll 11. It is desirable to limit the stretch at any stage to half the elongation at break. The process is particularly applicable to threads &c. made by extruding heat sensitive latex through hot nozzles according to Specifications 284,608, 292,964, 330,520, [all in Class 70], or 351,012. Specification 376,973 also is referred to.

Title: Improvements in or relating to a device for automatically lubricating moving lubrication points
IPC: F16N11/08
Filed: 1957-09-20
Abstract: 833,819. Lubricating. SCHLOSSHAUER, A. R. Sept. 20, 1957 [Sept. 20, 1956], No. 29709/57. Class 12 (3). A device for automatically lubricating a roller 19 of a conveyer chain comprises a pivotally-mounted lubricating mouthpiece 12 which is adapted to engage temporarily a lubricating point 18 in the roller pin 17 under the action of compressed air controlled by the movement of the roller 19. The mouthpiece 12 is carried by a lubricating head 9 which is slidable on slides 11 carried by an angle-plate 3 which is rotatably mounted on a vertical pin 2. In a cylinder 6, which is mounted on the angleplate 3, there is disposed a piston 7 which is coupled by a piston-rod 8 to the lubricating head 9. The angle-plate 3 is held against a stop 36 by a spring 35. The ends of the cylinder 6 are connected by conduits 28, 31 to a control cylinder 26 in which a slide valve 25 is located. When a roller 19 moves from right to left it contacts a roller 20 carried by a cranked lever 21, 22 causing the valve 25 to move towards the left and putting the outer end 29 of the cylinder 6 into communication with a conduit 27 through which compressed air is supplied. This causes the lubricating head 9 to advance towards the roller pin 17 and the engagement of the lubricating head 12 therewith. When the roller 20 disengages the roller 19, a spring 24 moves the slide valve 25 back to its original position, thus causing compressed air to enter the end 30 of the cylinder 6, via a conduit 31, and effect the withdrawal of the lubricating head 9. Before its arrival at the lubricating position, each lubricating head is blown out and cleared by a stream of control pressure medium issuing from a spraying nozzle 33 supplied through a conduit 32 from the cylinder 26 on the return stroke of the piston 25. A shut-off device 371 having a stop-valve 41 is operated when the rollers travel in the opposite direction. Lubricant is supplied to lubricating head 9 through conduits 14, 15. In a modification, the piston 7 is spring-returned.

Abstract: 1472638 Aerials LIGNES TELEGRAPHIQUES ET TELEEHONIQUES 10 July 1974 [18 July 1973] 30623/74 Heading H4A In a multi-rod broadband aerial structure of the loaded monopole type the resonant frequencies of the various rods are selected in accordance with a simple mathematical series, e.g. arithmetical, geometrical, or logarithmical. The rods are arranged equidistantly around the outside of a cylinder, and in such a manner that a line linking the rods, taken in the order of their resonant frequencies, defines a star-form polygon in plan view. In an embodiment, ten metallic conductors 11 to 20 of length 1À5 m. are distributed uniformly around a 250 mm. diameter cylindrical surface, their lower ends terminating in a metal disc connected to a feeder, and their upper ends terminating in a dielectric material disc. The conductors are loaded with respective cores (cylindrical sleeves) 21 to 30 of low loss material, the dimensions, permeabilities and permittivities of which are chosen so that the resonant frequency of a rod of rank (N + 1) is 0À867 times the resonant frequency of a rod of rank N, and so that the order in rank of the rods, clockwise around the cylinder, is 1, 8, 5, 2, 9, 6, 3, 10, 7, 4 (,1). With the resonant frequencies of the rods of ranks 1 and 10 being 30 and 8À318 MHz, respectively, operation over that waveband with a standing wave ratio between 1À5 and 3À5 is achieved (Fig. 5, not shown). The assembly may be embedded in dielectric foam material, for additional mechanical strength. The metallic conductors 11 to 20 need not necessarily be of equal lengths, and the loading means may incorporate an arrangement such as that described in Specification 1,282,293. Another embodiment operating the band over 20-80 MHz is described with reference to Fig. 7 (not shown).
