Title: Lasers
IPC: H01S3/107
Filed: 1967-05-16
Abstract: 1,131,376. Lasers. INTERNATIONAL BUSINESS MACHINES CORP. 16 May, 1967 [13 July, 1966], No. 22563/67. Heading H1C. In a laser capable of emitting radiation of plural discrete wavelengths, the wavelengths generated in the active medium are directed into spatially separated individual resonator paths, and some of these wavelengths are selectively suppressed so that a required combination of the generated wavelengths is emitted by the laser. In this manner particular combinations of some of the wavelengths or colours produced by the laser are obtained. A basic arrangement using a laser tube 10 containing ionized argon gas is described, Fig. 1, the tube being provided with Brewster angle windows 12, 14. Eight distinct wavelengths are obtainable from argon, viz: 4579 Š, 4650 Š, 4747 Š, 4765 Š, 4880 Š, 4956 Š, 5017 Š and 5145 Š, these wavelengths being separated into spatially separate paths 26 by a prism 18. Each wavelength has its own resonator formed by a common reflector 16 and an individual reflector 22, oscillation in a resonator being suppressed by energizing an electro-optic switch 20. In an alternative arrangement, Fig. 3, the wavelengths 4956 Š, 4579 Š, 4650 Š and 5017 Š are inherently suppressed, and any one of the sixteen combinations of the remaining wavelengths may be selected by applying suitable potentials to electro-optic switches 70, 80, 86, 88. Suppression is effected by rotation of the polarized radiation produced by the Brewster windows. The wavelengths 4765 Š, 5145Š, 4727 Š and 4880 Š effective in the arrangement are directed to respective electro-optic switches and reflectors 42, 44, 46, 48 by a series arrangement of quartz crystals 56, 76, 82 of selected optical length and right triangular birefringent prisms 64, 78, 84, each quartz crystal rotating the polarization of transmitted wavelengths so that at the immediately succeeding prism one wavelength is reflected as an ordinary ray, e.g. 5145 Š at prism 78, and other wavelengths, e.g. 4727 Š, 4880 Š are transmitted as extraordinary rays. Thus a progressive reduction in the wavelengths transmitted takes place from prism to prism until only wavelength 4880 Š is transmitted by prism 84. A modification is described, Fig. 8 (not shown), for selecting combinations of three wavelengths. Combinations of wavelengths 4880 Š, 4650 Š and 5145 Š are selectable in the arrangement shown in Fig. 11, which differs from the previous embodiments in that a quarter-wave phase plate 158 and an electro-optic switch 160 together forming a polarization rotator 156 precedes each quartz crystal 154, 168. A plurality of the arrangements of Figs. 3, 8 and 11 each represented by a block 182, 184, 186 in Fig. 14 may be used, a digital light deflector 180 being provided for selecting one of the blocks. Details of the light deflector are given, Fig. 15 (not shown).

Abstract: 434,903. Maintaining equal speeds of motors. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Võsteras, Sweden. Aug. 3, 1934, No. 22670. Convention date, Feb. 8. [Class 38 (iii)] The driving unit of each of a number of machines, e.g. the printing units and folders of a printing press, comprises a three - phase commutator motor 1 speed regulated by brush displacement, mechanically coupled directly or by gearing to an asynchronous motor 2, one of the motors serving for the drive and the other for synchronizing at normal speed, and the functions being interchanged at crawling speed, the synchronizing motors being connected in parallel on their stator and rotor sides. At starting a switch 11 may be closed and the asynchronous motors 2 may be fed from a low-frequency supply to drive the machines at crawling speed, the commutator motors with their stator windings disconnected from the brushes acting as synchronizing machines. For normal running the motors 2 are connected to the supply of normal frequency and act as synchronizing machines, while the motors 1 serve for the drive. Alternatively, the motors 1 may serve as the drive at crawling speed, being fed from a low frequency supply and having their secondary windings disconnected from the brushes and short-circuited. In this case the motors 2 ensure synchronism at crawling speed, and act as the drive with the motors 1 maintaining synchronism at normal speed. The brushes of the motors 1 are displaced by motors 17 under the control of push-button switches 13, 14, and directional current relays 18, in the stator or rotor circuits of the motors 2, also control the motors 17 to prevent the motors 2 being loaded while they serve for synchronizing. The brushes of the motors 1 may be returned to the low speed position when the motors are stopped. The correct relationship of the machines is ensured by synchronizing relays 22 controlling contactors 21 in the stator circuits of the motors 1 as described in Specification 434,947.

Abstract: 1,200,953. Coiling. EVG-ENTWICKLUNGSU. VERWERTUNGS G.m.b.H. 15 May, 1968 [16 June, 1967], No. 23074/68. Heading B3E. A machine for coiling metal strip on a mandrel from which the completed coil is removed by a gripper mechanism is characterized in that said gripper mechanism includes at least two pivoted gripper arms coupled together so that they swing inwards from opposite sides into contact with the outer surface of a coil on the mandrel to hold it together when the gripper mechanism is in a first and second position, the gripper arms being arranged to set down the coil on to a delivery guide when the gripper mechanisn is in its second position. The strip of mesh 1 issuing from the mesh welding machine passes underneath the coiling machine and forms a loop controlled by limit switches 18 and 18a which stop and start the coiling machine. The strip passes under a guide roller 2 and over a control drum 3 which feeds the strip and also acts as a brake to restrain forward movement. The drum may comprise a number of equally spaced toothed wheels or chains equipped with U-shaped grippers guided by rails. From the control drum the strip passes between shearing blades 4, 4a and two guide rails 17, 17a to the mandrel 6 provided with anchoring slots 7, 7a. As soon as the desired length of strip has been coiled the grippers 10, 11, 11a move against the coil to prevent unwinding and the shear blades cut the strip. An ejector plate then pushes the coil off the mandrel, the coil still being held by the grippers which travel sideways on lateral guide rails 14. The grippers hold the coil to one side of the machine until the binding has been completed whereupon the grippers release the coil on to inclined delivery rails 19. In a modification, the mandrel consists of two stub mandrels each projecting inwards at the side of the coil, the stubs being retracted to allow the coil to be removed in the direction of advance of the strip.
