Title: Device for inspecting reflective surfaces having a rectilinear generatrix
IPC: G01B11/24
Filed: 1960-11-09
Abstract: 894,953. Optical testing apparatus; microscopes. SCHAFER, G., SCHAFER, O., SCHAFER, jun. G., and SCHAFER, jun. O., [trading as KUGELFISCHER G. SCHAFER & CO.]. Nov. 9, 1960 [Nov. 23, 1959], No. 38427/60. Class 97(1). [Also in Group XL(b)] A device for inspecting, for surface defects, a reflective surface generated by straight lines, e.g. a plane or a cylindrical surface, including a lens or the objective of a microscope, in which a beam from a light source is directed from above towards the surface over which it moves and from which it is then reflected, comprises a system of mirrors directing the beam along a line parallel to the linear generatrix of the surface before it is directed on to said surface, and the mirrors are arranged in relation to the light source and the surface under inspection in such a manner that the total length of the path of the light beam between the surface under inspection and the lens or objective of the microscope is maintained constant, and that the light beam always strikes the surface under inspection at the same angle. The reflected beam may be directed to a photo-electric cell detecting the variations of reflectivity of the surface, or the reflected beam may be viewed directly via the objective of the microscope. As shown, the beam 2 from a light source 1 is passed by a half-silvered mirror 3 and lens 4 to a pair of mirrors 5, 5 which are at right angles to each other. To scan a line on the surface 6, the mirrors 5 are moved in the direction of the arrows 7, and in all positions, the length of the path from the lens 4 to the surface 6 is invariable. The reflected beam is passed from the mirror 3 over the path 9 to a photo-cell 8, or may be viewed directly. A line on the surface is scanned by movement of the mirrors 5 through a distance equal to half the length of the line, and the surface is scanned by giving it movement transversely of the surface generating lines.

Abstract: 369,940. Twisting and doubling yarns, threads, or filaments. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and POOL, W., of British Celanese, Spondon, near Derby. Dec. 24, 1930, No. 38865. [Class 120 (ii).] Yarns, threads, or filaments are doubled by drawing a yarn or yarns from a supply package in a loop which is rotated around the package to twist the yarn, and associating with the twisted yarn a second thread drawn from a supply outside the twisting device which receives no substantial twist during the operation. A yarn 60, Fig. 4, 67, Fig. 3, is drawn from a bobbin on a platform 10 and passed through a flyer 27<1>, being thereby twisted, and is doubled with yarn 62, 65 from a bobbin 66, arranged outside the device, the yarn therefrom being led straight through the flyer 27, as shown in Fig. 4, or through the flyer 27, upwards and through the flyer 27<1> so as to join the yarn being twisted at the top of the flyer 27<1> and to be doubled therewith, as shown in Fig. 3, the latter arrangement imparting a doubling twist of more than one turn for each revolution of the device. The platform 10 may be maintained stationary or caused to rotate relatively to the flyers by gearing such as described in Specification 369,293. The thread may be collected by simple winding, or twisted and doubled with similar or other threads, for example by a ring spindle apparatus, or the thread may be wound at an intermittent rate by means such as described in Specification 358,585 to cause the degree of doubling to vary. Yarns of different materials or characteristics, for example cellulose acetate, wool, silk, cotton, or cellulosic artificial silk, may be doubled and, by adjustment of the tension, the structure may vary from a covering of one yarn by another to a spiral arrangement of one on the other or a close intermingling.

Title: Mounting tubes in tube plates
IPC: F28F9/16
Filed: 1970-08-13
Abstract: 1315179 Welding by pressure; jointing by tube expanding SULZER BROS Ltd 13 Aug 1970 [23 Sept 1969] 39108/70 Headings B3J and B3R In a method of securing a tube to a tube plate a first explosive charge is used to expand a first part of the tube within the tube plate and a second explosive charge is used to weld a second part of the tube to the tube plate. The tube 3, Fig. 1, may be preformed with expanded collars 10, 11, detonation of a first explosive charge 24 within a pressure transmitting insert 20 serving to expand that portion of the tube between the collars 10, 11 against the tube plate. The second explosive charge 25 which is detonated by the explosion of the first welds the tube to the tube plate at the end portion 4. The explosive charges 24, 25 are in the form of explosive cord and the first has a high detonation velocity, preferably greater than the sonic velocity in the tube wall. The second charge 25 is preferably greater than the first. In a second embodiment, Fig. 2, the first explosive charge 43 is disposed partly within a metal tube 51 which is surrounded by a cupshaped second explosive charge 48 and the tube plate has a conically flared end adjacent the second charge. The first charge 43 is detonated outside the tube assembly and the detonation travels along within the tube 51 with little effect on the tube 39. After passing the end of the tube 51 the second explosive charge 48 is detonated and welds the tube to the tube plate in the flared end portion while the remainder of the charge 43 expands the further portion of the tube 39 into firm engagement with the bore 35 of the tube plate 36. In a third embodiment (Fig. 3, not shown) a single detonator is used to detonate simultaneously two charges one of which is in the form of a cylindrically arranged explosive foil. In a fourth embodiment (Fig. 4, not shown) three explosive charges are used (one being cup-shaped as in Fig. 2) to weld the tube to the front and rear portions of the tube plate with an expanded intermediate portion. The tube plate may be provided with a hood which is evacuated during the mounting operation to reduce the noise nuisance.

Abstract: 1,124,351. Hybrids. GENERAL ELECTRIC CO. Ltd. 14 Sept., 1966 [15 Sept., 1965], No. 39478/65. Heading H4R. A circuit for transition from four-wire to two-wire signal paths comprises two pairs of a four-wire line terminated in a " send " amplifier 4 and a " receive " amplifier 5 respectively. A " hybrid " has a terminal 1 connected to the two-wire line, a terminal 2 connected to the input of the " send " amplifier 4 and a terminal 3 connected to the output of the " receive " amplifier 5. The remaining wire of the twowire line, the other input of the " send " amplifier 4 and the other output of the " receive " amplifier 5 are connected to a common earth line 6. The input stage of the " send " amplifier is the emitter electrode of a PNP transistor 7 connected in common base configuration. The input impedance is reduced by negative feedback (not shown). The " hybrid " comprises a PNP transistor 12 providing one of two paths to the input of the " send " amplifier 4. When a source is connected to the terminal 1, the applied signal is transmitted by the transistor 12 to the " send " input terminal. In the case of a received signal from the receive pair of the four-wire line, the transistor 12 acts as an emitter-follower and a signal is developed across the two-wire line connected to the terminal 1. The " receive " amplifier 5 also supplies signals through a balancing resistor 14 and the transistor 12 to the " send " amplifier 4 but these signals are of opposite phase and cancel.

Abstract: 1327472 Electro-optic display device XEROX CORP 18 Aug 1970 [20 Aug 1969] 39725/70 Heading G5C A display device comprises transparent support plate 11 having a transparent electriccally conductive coating 12 which acts as a full area electrode, and electro - optic imaging material such as "liquid crystals" which is contained between a spacing gasket 13 and coating 12. Three composite eletrodes have mutually insulated parts 29, 30 which are mounted on plates 11, and these electrodes are stacked to one side of the unit containing the imaging material. When electrical circuit 15 is completed one of electrode parts 29, 30 is at a different potential to electrode 12 and the electric field passes through the imaging material and thereby activates the latter to form an image corresponding to the shape of the electrode part 29 or 30. Initially, the imaging material may be opaque and the image produced is transparent, so that transmitted light from source 26 shines through the image. In one embodiment electrode parts 29, 30 and electrode 12 may be placed on both sides of the imaging material and when one of parts 29 or 30 is activated then the electrical circuit is completed by activating the electrode 12 which is on the opposite side of the imaging material. Electrode 12 may also not be required because parts 29, 30 on each of the composite electrodes can be operated at the same potential so that together they form a full-area electrode. In another embodiment contrast enhancing is achieved by placing a pair of polarizers on opposite sides of the display device, with their respective planes of polarization crossed.
