Title: Improvements in or relating to tire inspection apparatus
IPC: G01N23/18
Filed: 1940-03-09
Abstract: 539,304. R÷ntgen-ray apparatus. FIRESTONE TYRE & RUBBER CO., Ltd. March 9, 1940, No. 4459. Convention date, July 25, 1939. [Class 98 (i)] A tyre-inspection apparatus comprises an X-ray tube and a fluorescent screen spaced apart to admit between them a portion of a tyre while mounted on a wheel on a vehicle, the focal point of the X-ray tube being nearer one margin of the screen than the other so that the rays pass through the tyre at an angle to the tread portion. As shown, a platform 14, normally movable on castors 15 but adjusted to be held stationary by lowering feet 16 by means of a pedal, carries a housing 25 in which is mounted a lead-lined box 26 containing an X-ray tube the focus 27 of which is so positioned that most of the rays are downwardly inclined and pass at an angle through the tread portion of the tyre. The tube is cooled by a fan 30 in the housing 25 and also by oil from a reservoir 44 in the back of a protective lead-coated steel protective plate 32. This plate is spaced from the housing 26 to admit a tyre 22 on the wheel of a jacked-up vehicle to be positioned between the housing and a fluorescent screen 33 mounted in the lower part of the plate. The screen is observed through a conical visor 35. Pivotallymounted protective plates 36 are connected by a spring 38 which holds them against the face of the tyre. When turned down to facilitate the positioning of the apparatus in relation to the tyre, each plate operates one of a pair of semi-connected switches 100 to prevent energization of the X-ray tube. The tyre may be marked by chalk &c. held by an arm 40 carried by a rotatable and slidable spindle 41 operated from in front of the panel 32 by a lever 42. In a modification the tyre rests on two rollers, one of which can be rotated from the front of the panel to rotate the tyre. In another form of apparatus, the car is run on trackways into a protective enclosure arranged over a pit in the upper portion of which is an oval track on which runs a motor-driven carriage supporting the X-ray tube, which may thus be positioned behind any one of the car wheels. A fluorescent screen is arranged in the wall of the enclosure in front of each wheel. The car wheels rest on pairs of rollers arranged in the trackways, one roller of each pair being rotatable by a motor to rotate the wheel. In another form, either the front or rear wheels of the car are similarly supported on rollers between a pair of protective walls each containing a fluorescent screen, and the X-ray tube is carried by a turn-table so that it may be positioned behind either wheel.

Abstract: 114,341. Harris, F. March 29, 1917. Differential speed indicators; time-distance recorders; speed indicators operating by sighting acrial objects.-Consists of an instrument wherein the movements of an aerial target are reproduced to a known scale bv an indicator moving on an horizontal table which is adjustable in height to represent the height of the target. In the apparatus shown, the height, angle of site, and speed of an aerial target are determined from observations taken at two stations. The triangle having the target as apex is reproduced in miniature in the object plane by two rays of light produced by electric lanterns controlled respectively by the home sighting-device 10 and by a protractor device 33, 34, which is set in accordance with directions signalled from the distant station. The home sight 10, the two lanterns 12, 13 and the protractor 34 are all mounted in the same plane on an horizontal frame or shaft which is rotated by the sight to bring all the devices into the object plane. The rays are directed downwards on to an horizontal indicator 46 which is adjusted over an horizontal table 39, which itself is adjusted in height, until the rays fall beyond their points of intersection on two spots on the indicator spaced apart a distance equal to the distance between the pivots of the lanterns. The indicator 46 may be fitted with a pencil 46w, Fig. 11, to trace a graph on a map placed on the table. The pencil is moved up and down at regular speed by clockwork mechanism so that it marks a series of dashes, thus recording the speed of the target. A wheel 46m rolling on the table is provided with a clicking device whereby the speed of the target can be determined by counting the clicks in a given period of time. Reference has been directed by the Comptroller to Specification 13213/15, [Class 97 (i), Optical systems &c.].

Filed: 1928-02-22
Abstract: 288,131. Fabriques des Montres Zenith, (Assignees of Joriot, C.). March 31, 1927, [Convention date]. Centrifugal speed indicators.-Comprises apparatus in which the indicating pointer is moved by the relative displacement of two members one rotated corresponding to the speed to be measured and the other independently rotationally and axially movable with respect to the first, the relative axial movement resulting from a braking action on the second member varying with the speed. Fast on the shaft 1, Fig. 4 is a bushing 4 having a curved cam surface 5 on which engages a roller 7 carried by a loose sleeve 6, the lower end of which is disposed interiorly of the bushing 4. In the direction indicated by the arrow, Fig. 5, the bushing rotates the sleeve through the engagement of the cam and roller. The shaft 1 is connected to the shaft, the speed of which is to be indicated, and carries a disc 8 recessed on the under surface to receive the upper ends of members or tops 10 pivoted to a disc 12 fixed to a hub on the shaft. Balls 13 are provided between the tops and the recesses 9. On the speed increasing, the upper ends of the tops fly out and move plates 16 to operate levers 17 fulcrummed on adjustable knife-edges 21 to apply brake shoes 18 to the sleeve 6 thus retarding it according to the speed. This causes the roller to mount up the cam 5 and the sleeve to move axially. A forked member 22 resting on the sleeve is in one with a rack 23 which is thus moved to turn the pointer pinion 25. A sleeve 28 which can slide relatively to but not rotate independently of the shaft 1 is located inside the sleeve 6 and is surrounded by a spring 31 the ends of which are connected to the sleeves 6, 28 respectively. This acts as a return spring and is placed under tension as the speed increases. A spring 34 tends to bring the pointer to zero.,
