Title: Improvements in x-ray tubes
IPC: H01J35/04
Filed: 1956-12-31
Abstract: 808,238. X-ray tubes. MACHLETT LABORATORIES Inc. Dec. 31, 1966 [Jan. 12, 1956], No. 39633/56. Class 39(1). In an X-ray tube capable of producing large quantities of utilizable radiation the anode 20, Fig. 2, embodies a long, substantially plane, target surface 22 extending parallel with the axis of the tube. The cathode comprises a pair of incandescible filaments 33, 33a, Fig. 4, extending along opposite sides of the target surface for substantially its full length. Each filament emits a stream of electrons, which streams have ribbon-like cross-sectional shapes formed by focusing means 29, 29a within which the filaments are located. The electrons initially pass towards an X-ray permeable window 15 forming part of the envelope overlying the target surface and maintained at cathode potential, the electrons being deflected by the window along arcuate paths towards the target. The window which may be of beryllium or beryllium oxide is constructed so as to have sides extending to or below the plane of the target surface to enable a major portion of the X-rays produced to pass out of the tube. The window may be a cylindrical shape or one of various other shapes which are described. The anode is cooled by cooling fluid entering through a conduit 27 into a chamber 24 inside the anode and passing out through a second conduit 28. The focusing members 29, 29a which also support the filaments are mounted on a cradle 31. The filaments are insulatedly supported by the members 29, 29a at one end but are electrically connected to them and hence to the cradle 31 and metal housing 11 at the other end. Electrical connection to the cathodes is made through terminals each of which comprises a metal cap 40 sealed to a glass cylinder 42 which is in turn sealed by a collar 43 to the housing 11.

Title: Apparatus for fixing shoe last position
Inventor: VINKLAREK ZDENEK
IPC: A43D3/12
Filed: 1966-09-15
Abstract: 1,126,255. Boots &c. ZAVODY PRESNEHO STROJIRENSTVI GOTTWALDOV, NARODNI PODNIK. 15 Sept., 1966, No. 41218/66. Heading A3B. Apparatus for holding a last e.g. in a lasting machine, consists of a carriage 1 having a last pin 2 and a toe support 37 which is automatically moved to its correct position according to the size of the last when the carriage 1 is moved in the machine. The last pin 2 is slidable heightwise in the carriage 1, its position being adjusted by a transversely sliding wedge 3 which can be locked in position by a pawl 24 engaging a rachet on the wedge 3. The toe support 37 is slideable heightwise in a slide 34 which can move lengthwise of the shoe along guides 32 on the carriage. The lower end of the toe support 37 rests on an inclined surface 33 so that as the slide 34 and toe support are moved lengthwise of the shoe the toe support 37 moves to its correct heightwise position. The carriage 1 can be moved lengthwise in the machine by bolt 43 which is fixed relative to the machine and which is screwed into the carriage. The bolt 43 is rotated until a shoe part e.g. the heel end of the last, is correctly positioned in the machine. The lower end of a pinion 36 mounted in the carriage 1 meshes with a rack 42 fixed with respect to the bolt 43 so that movement of the carriage 1 causes rotation of the pinion 36. The upper end of the pinion 36 meshes with rack teeth on the edge of the slide 34, rotation of the pinion 36 causing lengthwise movement of the slide 34. The gear ratio between the rack 42, pinion 36 and slide 34 is 2:1 so that movement of the carriage 1 by the bolt 43 causes a twofold movement of the slide 34, thus moving the toe support 37 to its correct position according to the size of the last. The apparatus also includes a heel mould 15 which is carried by arms 13 having slots 13<SP>1</SP> which co-operate with pins 12 on the carriage 1. Rollers 17 on the arms 13 engage a cam slide 9, movement of the cam slide causing the heel mould 15 to move forwardly until it engages the heel end of the last and then causing the arms 13 to move inwardly to clamp the heel mould 15 about the last. The cam slide 9 is moved by a lever 6 which is actuated by a cam 22 on a shaft 21 which is rotated by a crank 27, 28. Rotation of the shaft 21 also causes a pin 23 to move out of engagement with the pawl 24 so that the last pin is locked in position and also rotates a hollow nut 26. The nut 26 is screwed into a slide 30 having wedges which co-operate with wedges on the inclined surface 33 so that rotation of the nut 26 causes heightwise movement of the surface 33. This causes the toe rest 37 to move heightwise and clamp the last against an insole rest 38 which is pivoted to the slide 34. A side gauge 40 is also secured to the slide 34.

A carriage 16 having rollers 18 runs on the first track while the second track runs between the rollers so that the carriage can be extended from either end of the track 11 to provide a support for the second track 19 to be moved to position 5a or 5b, the side 20 of the cover 5 being attached to the truck 19 to move therewith. Stops limit the extension of the carriage 16 and of the tracks 19 relative thereto. In a modified track construction, Fig. 5, each U-shaped carriage 16<SP>1</SP> runs by rollers 25 on an L-shaped track 11<SP>1</SP> while a similarly U-shaped second track 21<SP>1</SP> runs by rollers 26 on the top of the carriage 16<SP>1</SP>. Retaining rollers 27, 28 on the carriage 16<SP>1</SP> and track 11<SP>1</SP> prevent relative tipping of the tracks and carriage when in the extended position. (For Figure 1 see next page.)

Abstract: 1366739 Deflecting light PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 Sept 1972 [15 Sept 1971] 42240/72 Heading H4F [Also in Division G3] In a digital light deflector comprising electrooptic polarization switches 1-6 and birefringent elements 1<SP>1</SP>-6<SP>1</SP>, incorrect action of switches 1-6 due, for example, to fluctuations in the applied voltage or the form of the electric field in the switch, to changes in the temperature dependent electro-optic constants of the switch, or to variations in the optical wavelength, gives rise to additional deflected beams forming an undesired background. In the arrangement of Fig. 1, a further polarization switch 7 is operated so as to render the desired beam with a predetermined plane of polarisation so that it may be transmitted through a polarization separating element 8. At least part of the undesired beams has an orthogonal polarization and is deflected at 8 to a photodetector 9 the output of which is minimized by means of an arrangement wherein the switching voltage V s  applied to switches 1-6 is controlled, thereby reducing the intensity of the background light. In setting up the apparatus a bias voltage V v  may be initially set when all the switches 1-6 are inoperative. The element 8 may be a Glen- Thomson prism as shown, a single birefringent prism plus an isotropic compensating prism, Fig. 2 (not shown), or a birefringent plate disposed to reflect light of one polarization and to transmit light of the other polarization. A plurality of deflectors of the type shown in Fig. 1 may be disposed in series.

Title: Slow-blowing fuse-link
IPC: H01H85/06
Filed: 1977-10-11
Abstract: This fuse insert has a first fusing conductor (3) which is formed from a first metallic material (for example copper). Said first fusing conductor (3) is surrounded by a sleeve (5) consisting of a second metallic material (for example tin). If relatively high currents continue for a relatively long period, these materials form a resistance-increasing alloy. The heating of the fusing conductor (3) which takes place in this case can finally lead to said conductor melting through. A second fusing conductor (4), without any sheath, is connected in parallel with the first fusing conductor (3), of higher conductivity. The conductance of the second fusing conductor (3) [lacuna] even in the state after formation of the resistance-increasing alloy between the sleeve (5) and the first fusing conductor (3). At relatively low current intensities, the current initially flows via the first fusing conductor (3) and, at relatively large current intensities, also via the second fusing conductor (4). Heating and alloy formation of the first fusing conductor (4) are thus slowed down. The response characteristic can in this case be determined by unambiguous parameters. A specific, reproduceable response characteristic can thus be achieved for relatively high rated-current intensities. <IMAGE>

Title: Improvements in or relating to a method of and apparatus suitable for use in measuring any change in length of an optical path between a source of optical radiation and a primary image of the source
IPC: G01B11/00
Filed: 1967-09-21
Abstract: 1,207,173. Photo-electric measuring apparatus. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Sept.21, 1967, [Sept.21, 1966; April 13, 1967], No.43103/67. Heading G1A Any change in the length of an optical path between a light source 2 and a primary image 2a thereof is measured photo-electrically. The apparatus is set up using a reference reflective surface 1 which reflects light from the source 2 passing through objective 3, back through the objective and via semi-reflective mirrors 4, 5, to form images respectively behind and in front of apertured diaphragms 2b, 2c, which are viewed by photo diodes 6, 7. When the outputs of the two detectors, which are amplified and fed to a differential amplifier, Fig. 2 (not shown) are equal, the surface 1 is at a known reference distance from the source. A test surface can be substituted for reference surface 1 and its displacement from the reference plane measured by monitoring the difference in the photo diode output. Figs.3-5 (not shown) detail support arrangements for the apparatus of Fig. 1, and illustrate means for moving the objective e.g. a micrometer screw arrangement, Fig.3, and a resistance coil - heated column, Fig. 4. The Fig. 5 support is for monitoring non-reflective surface displacement and comprises a mechanical spring- biased feeler to engage the surface and a plane mirror in contact with the top of the feeler. The light source 2 may be modulated, a synchronous demodulator being provided after the differential amplifier, Fig.2 (not shown). The source may be provided by light from the end of a fibre optic device. The objective 3 may be changed to change the sensitivity of the apparatus. To avoid inaccuracies due to different reflection characteristics of different surfaces, the ratio of the difference to the sum of the detector outputs may be taken. A modified form of Fig.1 is illustrated in Fig. 6 (not shown). The apparatus may be adapted for measurement of refactive indices of solids, liquid gases, vibrational characteristics of objects, movement control and machine tool servosystems. Two apparatuses on opposite sides of an object may measure its thickness. Specification 1, 207,174 is referred to.
