Title: Improvements in or relating to resonance inspection method
IPC: G01N29/12
Filed: 1944-09-21
Abstract: 650,423. Testing materials by supersonic vibrations. UNITED AIRCRAFT CORPORATION. Sept. 21, 1944, No. 18082. Convention date, Nov. 20, 1943. [Class 118 (ii)] In the interior inspection or measurement of a solid body by means of ultrasonic mechanical waves, the dimensions, elastic aeolotropy &c. are determined by reference to that frequency of the applied longitudinal, surface, or shear vibrations which produces resonance in the body, or the dimensions &c. of the body are distinguished from those of a standard body by failure of the resonance frequency of the latter to produce resonance in the body under test. The Figure shows apparatus similar to that described, e.g. in Specifications 641,095, 641,461 and 650,422, wherein supersonic voltage trains, of frequency adjustable by rotation of a dial 11, are applied by a generator 10, triggered from the linear sweep device 52 of a cathode-ray tube 50, to a damped quartz crystal 16, thus setting up vibrations in the wall of a metal airscrew blade 22 under test. At resonance frequencies (i.e. when the half-wavelength of the applied waves equals the effective thickness of the metal divided by an integer) the vibrations of the metal are sufficient to generate an oscillatory voltage across the damped crystal. Both the original voltage trains and this latter voltage are applied through an amplifier 24, and if desired a rectifier 26, to the vertical deflection plates of the tube 50, whereby resonance conditions may be observed and the corresponding frequency determined by a frequency meter connected to the generator 10. The dial 11 may be marked to indicate the frequency, or to read thiclmess directly. A separate receiving crystal may be employed, mounted beside or opposite to the sending crystal, and for curved surfaces the crystal may be ground to fit. The applied voltage train may have a long exponentially decaying tail, fluctuation of the end of which will indicate the occurrence of resonance. In the use of shear waves, different resonance frequencies when the crystal is mounted on aeolotropic material with its X axis parallel to different principal elastic axes will indicate different velocities of propagation, and if the X-axis is arranged at 45 degrees to the principal elastic axes, such frequencies may both be observed with one cementing of the crystal; if a mean frequency is applied, resonance will be established at both frequencies simultaneously, and a beat, indicated by an equally spaced waxing and waning of tail amplitude, will be produced. Specifications 569,858 and 569,874 also are referred to.

Filed: 1939-06-22
Abstract: 535,089. Antitoxins &c. LEDERLE LABORATORIES, Inc. June 22, 1939, No. 18191. Convention date, June 22, 1938. [Class 81 (i)] Solutions containing antibodies associated with proteins are purified by digestion of the proteins by means of an acid-acting proteolytic enzyine, the pH of the solution being adjusted to 3.0 to 3.2 and the digestion being carried on for about 2 to 6 hours until about 75 per cent of the protein is non-coagulable on heating. Precipitated material is filtered off and the filtrate may be dialysed and the active substances precipitated by the addition of ammonium sulphate. The precipitable is redissolved and dialysed to remove ammonium sulphate, rendered acid to precipitate some undesired material, brought back to neutrality and stirred with a suspension of tricalcium phosphate which removes further unwanted protein as the substances and the solution finally dialysed. The process is stated to be applicable to all known anti-toxins. Specifications 18,340/02, [Class 81], 468,676 and 493,101 are referred to.

Cigarette lengths C, Fig. 1, and mouthpiece stubs S which are to be united are carried lengthwise in succession on a conveyer 1 on which they are held by suction. In Fig. 1 double-length stubs are fed by a device 6 similar to that described in Specification 876,732 between pairs of cigarettes C from a continuous rod machine to form a group the components of which are subsequently butted together and moved sideways by a device 17 on to a uniting-band applying device 40, Fig. 2. The conveyer 1 is provided with a line of suction holes 3 and moves over a suction box. The leading cigarette of a group is gripped between a cam-operated finger 9 and a stationary block 15 to allow the stub to abut its end, the stub feeding finger 7 causing accurate positioning of the stub and leading cigarette. The group is carried towards a stop 24 which moves sideways with the pusher 17, a cam-operated arm 26 being simultaneously operated to abut the rearmost cigarette against the stub. As the group is moved sideways by a pusher 17, a resilient strip 35, Fig. 2, ensures accurate alignment of the components. A uniting band on a suction wheel 36 is rolled around the group in passage 40 and the united group is bisected on a drum 41. In a modification, Fig. 3, double-length cigarettes are fed from a hopper by a drum 52 on which they are bisected before being fed on to the suction conveyer 51, stubs S being fed into the spaces between the pairs of cigarettes. The retarding device 9 retards the rearmost cigarette of each pair so that it abuts the following stub and forms a group with the leading cigarette of the following pair. In Fig. 7 the retarding device comprises a pair of rotating eccentric discs 71 which are angularly adjustable relative to one another to adjust the period for which they grip a cigarette. In Fig. 8 the perforated conveyer is replaced by a pair of conveyers 81, 82, with a narrow suction slot therebetween. Specifications 871,514, 871,918 and 886,657 also are referred to.

Filed: 1929-06-14
Abstract: 334,306. Tourand et H. Guerrier, A. Oct. 31, 1928, [Convention date]. Actuated by springs.-The brake pedal or lever is connected by a rod 1 with the arm 3 of a bell-crank lever pivoted at 4 and carrying on its arm 5 a rocking lever 7 connected at one end to the brakes by a rod 8 and at the other end to a compression spring 12 which is compressed after the taking up of play in the brake gear and subsequently distends adding its effort to that of the driver. The rod 1 is pivoted to a pin 2 carried on the arm 3 of the bell crank lever connected by a pin 6 on its shorter arm 5 to the rocking lever 7. One end of the rocking lever is connected to the brake rod 8 and the other end is pivoted by a pin 9 to a rod 10 adjustably connected to the compression plate 11 of the spring 12 bearing on a swiveling stud 14 supported in the frame 15 of the apparatus. On the pin 2 is mounted a roller 16 which, when the brake pedal rod 1 is moved in the direction of the arrow abuts against the rocking lever 7 after a certain initial displacement. During the initial displacement the bell-crank lever 3, 5 and rocking lever 7 take up the position A, Fig. 4, the pin 9 reaching the position 9<1> so that the spring 12 is compressed. Continued movement of the brake pedal moves the rocking lever 7 about its pivot 6 by the roller 16, the parts taking up the position B and the pin 9 passing from 9<1> to 9<11> under the expansion of the spring 12 which is released from the action of the pedal rod 1. The spring thus exerts on the brake rod a pull which is added to the force exerted by the driver.
