Patent ES-342887-A1 (ES)
Title: Lasers
IPC: H01S3/107
Filed: 1967-07-11
Abstract: 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 , 4650 , 4747 , 4765 , 4880 , 4956 , 5017 and 5145 , 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 , 4579 , 4650 and 5017 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 , 5145 , 4727 and 4880 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 at prism 78, and other wavelengths, e.g. 4727 , 4880 are transmitted as extraordinary rays. Thus a progressive reduction in the wavelengths transmitted takes place from prism to prism until only wavelength 4880 is transmitted by prism 84. A modification is described, Fig. 8 (not shown), for selecting combinations of three wavelengths. Combinations of wavelengths 4880 , 4650 and 5145 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).

Patent ES-358229-A1 (ES)
Title: Ice dispenser having stages with different feed rates
IPC: F25C5/00
Filed: 1968-09-17
Abstract: Ice from a refrigerator falls into receptacle 4 and is discharged therefrom through opening 60 by means of conveyer 50, which comprises conveyer part 18 and conveyer part 61 which is mounted rigidly on the conveyer shaft and includes two passages 63, and scoop 70. The ice blocks are moved leftwards by conveyer part 18 so as to provide a surplus of blocks at the entry to conveyer part 61. Conveyer part 61 rotates as part of the conveyer so that scoop 70 entrains a block 72 which as the conveyer rotates moves up to position 721 and then slides forward into position 751 to be subsequently discharged at 60. A surplus of blocks thus passes through the conveyer portion 61 and is held up by wall 74 forming part of the conveyer. In this way the conveyer discharges a constant number of blocks per rotation from the blocks waiting at 74.

Patent ES-374416-A1 (ES)
Title: Method of transmitting data over a pcm communication system
IPC: H04L12/52
Filed: 1969-12-10
Abstract: Either one data channel having a high data rate, or several data channels of the same or mixed lower data rate or rates are transmitted in a channel of a TDM-PCM system having a high data rate. The data transmission is performed in synchronism with the PCM system. This is accomplished by having the data frame of the lower data rates related by a multiple to the PCM frame and by adding bits to the data code words to cause equality between the bits of the data code words and the bits of the PCM code words. Further the data is stored in a buffer store, where the bit addition is accomplished, and is read out continuously in the proper channel time slot of the PCM system. To protect against false data frame synchronization due to data code words simulating the data frame synchronization signal, the added bits of certain of the data code words are employed to form a data frame synchronization code word. It is taught herein that conversion from binary coded bits to binary coded ternary code words provides an advantage in transmission of data in a PCM system.
