Title: Singaround type ultrasonic measuring instruments
IPC: G01F1/66
Filed: 1971-04-19
Abstract: 1329176 Ultrasonic measuring instruments TOKYO KEIKI KK 19 April 1971 [10 Feb 1970] 21303/71 Heading H4D In a sing-around type ultrasonic measuring instrument, in which reception of an ultrasonic signal triggers the next transmission of a signal, the triggering instant is stabilized by providing automatic gain control for a receiver amplifier to stabilize the received signal amplitude and by delaying the triggering a fixed amount relative to the reception instant. The Fig. 3 embodiment for measuring fluid flow in a pipe 2 comprises a transmitter circuit 6 triggered by a pulse P t  (Fig. 2F) from control circuit 5 to energize transducer 3. The resulting received pulse train from transducer 4 is fed via amplifier 7 to a level detector circuit 9 having a threshold L (Fig. 2A) and to gate circuit 11. The output P L  (Fig. 2C) of detector 9 (e.g. Schmitt trigger) triggers monostable circuit 10 to provide a pulse P G  (Fig. 2D) of fixed length for enabling gate 11 and for actuating circuit 5 to give the pulse Pt. The gate output signal (Fig. 2E) is smoothed at 12 to provide the gain control signal, indicative of received signal amplitude, for amplifier 7. A stable received signal amplitude means that the leading edge position of pulse P G  is stable. The delay provided by pulse P G  is stated to assure more stable detection of the received signal amplitude than would be the case if reception of an ultrasonic signal caused immediate triggering of the next transmission signal. An output signal at the sing-around frequency is taken from terminal 8.

Filed: 1922-08-04
Abstract: 185,399. Nishina, E. Aug. 4, 1922. Artificial leather; coated paper; papier mÔchÞ. -Fibrous pulp mixed with adhesive material is solidified in thin films by projecting it with air under high pressure on to a slowly moving surface of gauze, felt, &c.. After drying the material is removed from the surface and calendered on rolls or pressed into moulds. Alternatively the pulp may be left adhering to the surface, which then serves as a reinforcement. The process is suitable for making materials such as pasteboard, paper mÔchÞ, artificial leather, belting, linoleum, and flooring. In the example shown the pulp suspended in a liquid sizing material is allowed to flow from a container 1 through an adjustable valve 4 on to a nozzle 5 through which air is blown under pressure. The pulp is thus projected on to the surface of an endless belt 9 supported by a roller 8 covered by a sucking device 7. The film formed is led on to a belt 11 and dried over a drum 13. Air is sucked from the surface of the nozzle by a fan 15 working in a cover 14.

Abstract: 660,194. Stamping. FISHER & LUDLOW, Ltd. Aug. 22, 1949 [Aug. 23, 1948], No. 22149/48. Class 83 (iv). A work-removing device for a press comprises a pair of relatively displaceable members secured one to each of the relatively moving tool carrying parts of the press, one of the members carrying a transfer element adapted to pivot about an axis parallel to the direction of relative movement of the press tools and means associated with the members to cause the transfer element to move into a position between the tools as they move apart. A bracket 12 secured to a fixed part of the press carries a nut 17 in which is mounted the screw-threaded lower end of a vertical rod 16 formed with a slot comprising a lower axially extending portion 23 joined to an upper axially-extending portion 24 by a sloping part 25, the parts 23 and 24 being spaced circumferentially at an angle of ninety degrees, The rod 16 is adjustable vertically by rotating the nut 17 by means of a screw 49 and may be locked in a given angular position by a fixable plate 18 having a tongue 19 engaging in the slot 23. A bracket 13 secured to a part of the moving press-head carries a nut in which is clamped the upper end of a threaded sleeve 26 through which the rod 16 projects. A collar 27 on the lower end of the sleeve carries a member 29 through which a pin 30 projects so that its head 31 is within the slot formed in the rod 16. Pivotally mounted on the collar 27 by a pin 42 is a work-receiving tray 36, a flange 43 of which is held against downward movement by a stop 44 but is allowed a limited upward movement by springs 45. Thus the tray may tilt below but not above the horizontal plane. In the position shown, the tray is out of the path of the upper tool, but as the tool is raised after a pressing operation, the sleeve 26 and collar 27 are raised relatively to the rod 16, the head 31 of the pin 30 rides up the groove from the portion 23 into the portion 24, thus causing the tray 36 to rotate about the axis of the rod 16 into a position to receive the work as it is stripped from the upper tool. On the next down-stroke, the tray and work are swung away from the tool. In a modification, the descent of the sleeve relatively to the rod is limited by an adjustable nut on the rod, and the remaining down stroke of the bracket 13 is absorbed by a spring surrounding the sleeve. This limits the downward movement of the tray and leaves a greater space for the feeding of the stock over the lower tool.
