Title: Ultrasonic non-destructive pulse testing apparatus
IPC: G01N29/38
Filed: 1975-07-14
Abstract: 1521302 Ultrasonic inspection devices MAGNETIC ANALYSIS CORP 14 July 1975 [15 July 1974] 29444/75 Heading G1G [Also in Divisions H3-5] In pulse-echo ultrasonic NDT apparatus the received amplified signals are supplied to cathoderay tube means for display and horizontal sweeps are developed, with provision for expansion of selected regions of interest in the complete received video signal. Initial ramps 105 are generated which are of predetermined amplitude 113 and synchronized with the transducer driving pulses. The ramps are applied through variable attenuator means (106), Fig. 7 (not shown), to limiter means (109), having a limit level 112 less than the ramp amplitude. By adjusting the attenuator means, sweeps of different time duration but of the same peak amplitude can be developed. These are amplified and supplied to the CRT. The sweeps are also used to develop a signal gate of adjustable position and width, and which will maintain its position on the CRT display as the sweeps are expanded. To this end, the peaks of the sweeps are clamped at an adjustable first level 126, 126' which is less than the sweep amplitude with respect to a reference level (usually ground). A second adjustable level 141 is established intermediate the reference and first levels. Switch circuit means produces a signal gate during the portion of a sweep lying between the reference and second levels.

The tubes in the form shown, are accommodated in a widened portion 29 of the gas duct. The headers are arranged out of the direct line of gas flow, the return headers 15 being accommodated in pockets 3-5 (and 6, not shown) and the upper headers being disposed in the duct wall openings and being sealed therein to prevent leakage of gas. Seals may also be provided around the headers 15.

Title: Improvements in or relating to a window system
IPC: E05F11/48
Filed: 1945-11-06
Abstract: 602,060. Operating windows. TRICO PRODUCTS CORPORATION. Nov. 6, 1945, No. 29564. Convention date, Nov. 18, 1944. [Class 20(iii)] In a window operated by a fluid motor 13 including a piston having relatively movable sections 16, 18, Fig. 2, one of which carries a lock 23 which prevents direct manual opening of the window, manually operable means 34 are connected to the piston sections for opening and closing the window without resistance from the lock if the motor should fail. In the form shown, a vertically sliding vehicle window 2 is supported at 5, 5<1> by two parallel flights 6 and 7 of an endless flexible belt 12 which passes over pulleys 9, 10, through the motor 13 and twice over pulleys 11, 8, the part of the belt between 5<1> and 14 being detachable. The piston slides on fixed rods 19 and the section 18 carries an inverted cup 21 housing a toggle lock 23 having shoes 22 pressed lightly on the rods 19 by a spring 24. The levers 23 fit in notches in a lug 26 riveted to the belt 12 and normally held against the section 16 by a spring 17. Thus the lock is operated by a left-hand pull on the belt caused by an attempt to prise open the window, but permits fluid-imparted movement of either piston section to move the lug 26 and thus the belt 12, to open or close the window. For operating the window by hand, belts 41, 42 pass over a drum 36 turned by a handle 34, and are connected to opposite sides of the piston. The belt 41 is clamped at 44 to the belt 12, (and the operating handle may alternatively be provided here), so as to produce a direct pull on the lug 26 in the lockfreeing direction to close the window, and the belt 42 is hooked to the piston section 16 which is coupled to the housing 21 so as to pull on the section 18 to open the window. A counterbalancing spring is coiled in a drum, coaxial with the pulley 10 to help in closing the window. Packing means are provided for the movable parts in the motor, and the piston sections have flap valves for normally equalising the pressure on either side.

Filed: 1924-12-09
Abstract: 243,178. Drabble, H. Dec. 9, 1924. Lantern fronts.-A glass front for a vehicle lamp comprises a pair of glass plates 1, 2, the outer surfaces of which are smooth whilst the inner surfaces are provided with rectangular horizontal interengaging teeth. The two plates are secured together by adhesive 3 and are secured in the lamp either by providing one of the plates with an outwardly extending rim, or by mounting the plates between a detachable flange 10 and a fixed flange 9 on a metal frame 8 having a rim 12. The teeth may be formed integrally with the plates, or they may be secured to them before assembly, and some or all of their horizontal surfaces may be silvered to reflect upwardly directed rays of light downwardly. The teeth, which are slightly smaller than the spaces between them, may have their edges slightly rounded, their sides slightly tapered, and their rising faces sloped instead of vertical. The teeth may have the same or different depths, or may be stepped so as to be prismatic in general outline.

Abstract: 1,165,225. Pneumatic conveyers. GEMA AG. APPARATEBAU. 27 June, 1967 [28 June, 1966], No. 29585/67. Heading B8A. Flow of granular material 6 from a hopper 5 into a pneumatic pipe-line 1 is controllable while the propellant gas stream remains constant. As shown, compressed air is fed to the pipe-line 1 through a nozzle 2 creating an annular space 3 of reduced pressure. Opposite the hopper discharge duct 4 the pipe-line is provided with a duct 8 connected through a valve 9 to atmosphere. On opening the valve 9, air is drawn into the pipe-line 1, thereby reducing the vacuum in the space 3 and reducing the rate at which material 6 is drawn into the pipe-line. In a modification, Fig. 2 (not shown), compressed nitrogen is fed to a Venturi tube and the hopper discharge duct and a nozzle open into the tube at the zone of constriction. The nozzle is connected to the nitrogen supply conduit through a control valve.
