Title: Improvements in and relating to card indexes
IPC: G06K21/04
Filed: 1946-07-17
Abstract: 643,651. Statistical apparatus. PERWOLF, F. July 17, 1946, Nos. 21402, 21403 and 21404. Convention dates, Oct. 4, 1941, Jan. 7, 1942, and May 1, 1942. [Class 106 (i)] A card index, for use with a card selecting device of the selector rod type, in which the cards have on each side of a separating line a group or field of rows of perforations is characterised in that in each of both groups are arranged at least two or more rows of holes parallel to the line of separation and in that data is represented in each group by slots extending normal to the line of separation. As shown in Fig. 1, a typical card in this index has two groups O, U of rows of perforations and the number " 2426 " is represented thereon in each group by slots extending from particular holes to the top and bottom of the card. The extreme right-hand vertical column " g " is slotted to represent " 4," the number of significant digits in the number " 2426." Sorting or segregation is effected by the repeated insertion of a selector rod in complementary holes in each group followed by a separating movement of said rods, whereupon the cards are positively moved. Any desired number of groups of perforations may be employed to suit the system of classification in which the cards are used. In another example, not shown, the data representing slots do not extend to the edge of the card but only to an extra row of perforations so that the slots are enclosed. In a further example, Fig. 3 (not shown), the slots extend from the particular perforations to the adjacent perforation. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 643,710. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to optical masers
IPC: H01S3/223
Filed: 1963-05-30
Abstract: 1,039,788. Optical masers. WESTERN ELECTRIC CO. Inc. May 30, 1963 [June 15, 1962], No. 21619/63. Heading H3B. In a gaseous optical maser the gaseous medium comprises a mixture of two gases, an auxiliary gas having an energy system characterized by a metastable energy state above the ground state and an active gas having a polyatomic molecule characterized by at least one repulsive excited molecular energy state, the molecule of the active gas including at least one atom having a plurality of energy states above the ground state and the repulsive molecular energy state terminating in an upper energy state of the atom. The invention is based on the fact that the Franck-Condon principle for transitions between energy states due to electron-molecular collisions may be extended to atom-molecule collisions and to grazing molecule-molecule collisions. Thus as illustrated in Fig. 1, showing a plot of the energy of various electronic energy states as a function of nuclear separation of the two atoms of a diatomic molecule, the dashed vertical lines indicate a region in which the Franck-Condon principle indicates excitation from the ground state of the molecule, curve I, to be probable, and the dashed horizontal lines indicate an energy range range #E within which there is a substantial probability that energy will be transferred to the repulsive molecular state, curve II. Thus molecules may be dissociated into excited states of their component atoms by inelastic collisions with particles of an auxiliary gas in a metastable state having an energy with the range #E. In order for laser action to be possible the active gas comprises at least one atom having a plurality of energy states of which at least a pair of states above the ground states are optically connected, and the repulsive molecular states terminate in the upper energy level of the signal transition or in a lower lying metastable level having a relatively large cross-section for excitation to the upper laser level or in a higher level which relaxes or decays thereto. Suitable gases are as shown in Fig. 3 (not shown), which illustrates portions of the energy level systems of molecular and atomic oxygen and of neon, argon and krypton. The solid curves represent the energy of various attractive states of the oxygen molecule as a function of nuclear separation and the dashed curves represent excited repulsive states which extend over the energy range indicated by the shaded area. As shown, metastable states of neon, argon and krypton denoted by asterisks, and obtained by collisions with free electrons in a gas discharge, substantially match preferred repulsive states of oxygen. Energy is thus transferred by resonant processes during inelastic atommolecule collisions from the noble gases to the oxygen molecules which latter then dissociate to the preferred states of atomic oxygen resulting in a negative temperature medium being formed and laser action to take place at the required frequency. The oxygen may be replaced by nitrogen.
