Title: Improvements in and relating to apparatus for measuring a parameter of vehicle traffic
IPC: G08G1/015
Filed: 1963-04-24
Abstract: 1,035,246. Ultrasonic pulse echo systems. GENERAL SIGNAL CORPORATION. April 24, 1963 [May 9, 1962], No. 16136/63. Heading H4D. [Also in Division G4] Apparatus for measuring a traffic parameter, Fig. 4, comprises means responsive to the entry of a vehicle into a detection zone (relay SP1) for applying a first signal to a summing circuit 41 for a predetermined time; means (relay AVP) for applying a second signal to the summing circuit for the duration of the occupancy; and storage means 44 connected to the output of the summing circuit. As described, a sonic vehicle detector of the type disclosed in Specification 931,125 causes relay AV to release during the time in which a vehicle is present in the detecting zone. This operates relay SP1 for a predetermined time via monostable circuit 36 and relay AVP for the total time during which the zone is occupied, changing the charge on capacitor 44. If a flow of traffic passes the detection zone, the resulting potential at the output of summing amplifier 41 is an analogue of the mean traffic speed, if a standard vehicle length is assumed. In order to modify the assumed standard length in the case of lorries, a further relay HV is released by extra high vehicles passing through the zone and energizes relay SP2 for a further predetermined time, to modify the signal applied to the summing amplifier 41. The resulting output is applied to a meter which may be calibrated in speed, and to limit relays HS, MS, LS which operate at predetermined speeds. Fig. 5 (not shown) discloses an arrangement in which individual vehicle length is measured by integrating the speed thus measured over the detecting zone occupancy time.

Filed: 1925-06-23
Abstract: 238,838. Dunlop, S., (Metallschlauch- Fabrik Pforzheim vorm. H. Witzenmann Ges.). June 23, 1925. Corrugating.-In a machine for making flexible metal tubes by closing-up the corrugations of a corrugated tube, the closing-up tools also serve to feed the tube through the machine. The tube is passed through two pairs of slides 11, 12 which are closed by cams 22, 24 and levers 21, 25 and are opened by springs. The slides 11 are mounted on a cross-head 17 which is pushed forward on the bed by cams 16, through levers 15, rods 14, and toggles 13 and is returned by a cam 19 through a lever 18 connected to the levers 15 by a link 20. With the slides closed, the crosshead completes its forward motion to close up the corrugation as shown in Fig. 7. The slides 11 then open and the cross-head travels to its rearward position, whereupon the slides 11 close. At this time the slides 12 open and forward motion of the cross-head results in the tube being fed forward by the space of one corrugation. The slides 12 then close and during the completion of the forward motion of the cross-head the next corrugation is closed up. In order that the tube may be inserted through the slides, the slides 12 are moved into the open position and the slides 11, which in this position are normally closed, are opened by reversing the eccentric bushings 27 on which the levers 21 are mounted.
