Title: Method and apparatus for detecting defects on surfaces
IPC: G01N21/91
Filed: 1963-02-08
Abstract: 993,985. Detecting flaws in surfaces. UNITED STATES STEEL CORPORATION. Feb. 8, 1963 [Feb. 23, 1962], No. 5326/63. Heading G1S. Surface defects on solid articles are detected by applying a vaporizable material to the surface of the article, the material having the characteristic of being able to penetrate into surface defects on the article, thereafter removing substantially all of the material which has not penetrated into any surface defect, maintaining the article in a condition which will allow material remaining in any defects to vapourize,and detecting vapours emitted from the material in the defects. In one embodiment, liquid trichloroethane is applied by a nozzle 20. The surface is subsequently cleared by air jet 24 and the body 11 is then heated by a coil 28 and vapour from any defects is detected by a chlorine detector 30. In an alternative embodiment for use when the body 11 is at a high temperature, a solid salt is applied to its surface, which due to the heat of the body, flows into any surface defects. The vapour escaping from the defects is detected by applying a flame to the surface. Any vapour of the salt imparts a characteristic colour to the flame and this may be detected spectroscopically.

Title: Producing photographic prints from originals
IPC: G03B27/73
Filed: 1975-02-07
Abstract: 1486972 Photographic exposure control GRETAG AG 7 Feb 1975 [8 Feb 1974] 5427/75 Heading G2A [Also in Division H4] The printing exposure for each primary colour k of a photographic print is automatically controlled in accordance with the respective area density Dk of the original in order to reduce the effects of colour dominants. D k  is derived from colour density values determined in respect of each of a number of elementary areas of the original. Each density value is assigned to one of a number of classes, each class representing one of a number of pre-selected density intervals, and the frequency distribution of the values is determined. The density values in any class in which the frequency exceeds a prescribed threshold are assigned weighting factors, some of which are less than unity and none exceeds unity. The area density Dk is calculated according to D k  = D k  + A k .(D' k -D k ) where D k  is the arithmetic average of the density values of all the elementary areas, or of values representative thereof, D' k  is the weighted average of these values, and Ak is a constant.  In one arrangement a spot of light is swept repeatedly across the original, which is in the form of an edge-notched film strip, by a rotating polygonal mirror drum. Light passing through the film passes via a beam-splitter to three photo-sensors, responsive to respective primary colours. A reference density film is also sensed. The photosensor outputs feed a processor which performs the required calculation and controls a shutter and filters as necessary to produce the corrected print by passing light through the original when it has reached, and been stopped in, the printing position. The position of the film is monitored by reference to notch detectors at the scanning and printing stations. The processor digitizes and samples the outputs of the photo-sensors so as to obtain three density values at each of a number (e.g. 100) of elementary areas of the original. For each colour the values are allotted to an appropriate class: there may for example be 20 classes with an interval of 0.05 on a logarithmic density scale. The number of samples in each class is determined and if a threshold number N, which may not be the same for each class, is exceeded in a class a weighting factor is assigned to the samples in that class. For example, the weighting factor for N of the samples is chosen to be one and for the remainder is less than one (e.g. zero) or is progressively decreased. For those classes which contain N or less samples the weighting factor is one. In the calculation of Dk either the actual density value of each sample is employed or alternatively each value in a class is assumed to have the same value representative of the class. The weighting factors may be dependent upon the position of the sample in the original.

Filed: 1951-03-08
Abstract: 684,652. Machine-tool details. PONGRACZ, F. March 8, 1951 [March 11, 1950], No. 5609/51. Class 83 (iii). A feed device for the tools of automatic lathes and like machines comprises a rotating control cam on a main cam-shaft and a transmission mechanism co-operating with the cam and feeding the tool against the pressure of a return spring, the tool-feeding stroke being controlled by an auxiliary oscillatable cam. The main cain-shaft 1 of the machine carries a cam 2 which operates through linkage 3, 4, to oscillate an auxiliary cam 5 on a stub shaft 7. The cam 5 transmits motion through a double lever 11, 14, and adjustable pins 10, 15, to a spring-returned tool-slide 17. The cam 2 controls the time when the tool is to be brought into operation whilst the cam 5 controls the amount of feed movement given to the tool slide. The latter cam has a portion of rising profile 5a followed by a concentric portion 5b and further movement of the cam after the pin 10 has reached this position does not affect the tool. Further movements of the linkage 3, 4, due for example to undesirable movements of the cam 2 caused by whip in the cam-shaft 1 are not, therefore, transmitted to the tool-slide. A number of auxiliary cams 5 may be mounted on the same shaft with their profiles staggered and brought into operation on a common lever 11, 14, to cut various diameters on the work. The cam 2 in this case has a profile shaped to oscillate the shaft of the cams 5 in a number of steps.

As shown, when used in a film perforator, the claw 184 has a cam surface 180a, which preferably is biased into contact with a second cam surface 149a, which is reciprocated to produce little relative movement between the surfaces 149a, 180a. The claw 184 thus describes the dotted path shown in Fig.5. The cam 180 is attached to carriage 148 carried by springs 140, 156. Carriage 148 is connected to arm 102 by spring 170 so that surfaces 149a, 180a may move together. As shown the surface 180a is curved and surface 149a is flat but these surface shapes can be interchanged. The claw 184 may be changeable so that different film gauges and formats can be accepted.

Abstract: 897,370. Mechanical switches; actuation of switches. UHDE G.m.b.H., FRIEDRICH. Feb. 18, 1959 [Feb. 18, 1958], No. 5684/59. Class 38 (5). A switch operating mechanism, especially for the short-circuiting switch 16 of an electrolytic cell 19, comprises an actuating lever 2 and a torsion spring device 22 connected through gearwheels 24, 25 and a lost-motion coupling 13 to a switch-operating crank-shaft 11 biased by a spring 17. To open the switch, a shaft 1 is turned by the lever 2, and through linkage fi stresses the torsion spring of the device 22, the linkage moving slightly over-centre into a position in which it is retained by a stop (not shown). As this occurs, the shaft 1 through the gear-wheels turns a sector 13a of the coupling 13 until a radial edge of the sector moves a dog 13b secured to the crank-shaft 11. This moves the crank-shaft 11 from its deadcentre position so that the spring 17 can turn the shaft 11 to open the switch 16, until the dog 13b engages the other radial edge of the sector 13a. To close the switch, the torsion spring device 22 is released so that the torsion spring restores the mechanism to its initial condition. Specification 849,345 is referred to.
