Title: Information recording and retrieval
IPC: G11C17/00
Filed: 1964-09-02
Abstract: 1,082,407. Diffraction gratings. EASTMAN KODAK CO. Sept. 2, 1964 [Sept. 3, 1963], No. 35875/64. Heading G2J. [Also in Division G4] The respective bits of a binary coded character are recorded photographically, each bit being recorded as a diffraction grating pattern having a unique, uniform grating interval representative of that bit, and the grating patterns being superimposed to form a composite diffraction grating. When the composite grating is illuminated by a source and slit, the first order spectra produced by the various superimposed grating patterns occur at different positions on either side of the zero order line and may be detected by photocells to produce parallel signals representing the recorded information. The information may be recorded by apparatus in which photo-cells sense characters punched on a tape and gate respective oscillators, the outputs of which are of different frequencies and are mixed before application to a C. R. T. which records the superimposed patterns on a film. In an alternative recording apparatus, Fig. 8 (not shown), variable transmission elements in a plate produce unique grating patterns when illuminated by respective flash-lamps. The lamps are energized serially so that the patterns are superimposed as the film moves past. A different optical system, Fig. 9 (not shown) enables the lamps to be energized simultaneously. Several binary coded characters may be recorded on the same area of film if the film is rotated through a predetermined angle between the recording of successive characters. Illumination of such an area produces a pattern in which, Fig. 10 (not shown) the diametrically-opposed pairs of patterns represent the respective characters and the individual first-order spectra of these patterns represent the bits making up the character.

Title: Method of treating anemone bulbs
IPC: A01G7/00
Filed: 1961-10-06
Abstract: A method of treating anemone bulbs to prevent or modify their germination, comprises saturating the bulbs in water, e.g. for thirty-six to forty-eight hours at room temperature, surface-drying the bulbs, e.g. at 4 DEG  to 6 DEG C., preferably 4.5 DEG  to 5.5 DEG C. for seven to ten days, and then enclosing the bulbs in air-tight packages such as plastic bags.  If the packed bulbs are to develop no apparent germs, they are submitted to a temperature of 1 DEG  or 2 DEG C., or lower, for fifteen days or more.  If fully apparent germs are required, the drying temperature, after the seven to ten day period, is raised, over four or five days, to 13 DEG C., and this temperature is maintained for ten more days.

Patent GB-363087-A (GB)
Abstract: 363,087. Prepayment mechanism for electricity meters. LANDIS ET GYR SOC. ANON., 1, Hofstrasse, Zug, Switzerland. Nov. 12, 1930, No. 34094. Convention date, Nov. 20, 1929. [Class 27.] A coin-freed meter, of the kind in which a basic charge is registered by means of an additional turning moment, is so arranged that this turning moment acts on the meter only for a short time during each day or like extended period. In series with the current coil 4 is a time switch 5 and a switch 7 which is closed by the prepayment and opened by the meter after the consumption of a predetermined amount of energy. In the normal position of the switch 5 the main circuit of the current coil 4 is closed, but in the position shown this circuit is opened and the primary and secondary circuits 2, 3 of a transformer 1 are closed so that a constant current is supplied to the current coil 4 in order to register the basic charge. The switch 5 is in the position shown for a short time only, for example 10 or 15 minutes, preferably at a period of the day when no current is usually consumed, e.g. between 3 and 5 a.m. The clock operating the time switch may also close a relay circuit which switches in a basic charge counting train or changes over the meter drive from the consumption counting train to the basic charge counting train. The switch 5 may also have an intermediate position in which both the main and transformer circuits are opened. Alternatively the switch 5 may control the current circuit of the transformer only. In this case no separate registration of the basic charge is possible.
Patent GB-364627-A (GB)
Abstract: 364,627. Colour photography. NORDMANN, C., Observatoire de Paris, Avenue de l'Observatoire, Paris. Oct. 1, 1930, No. 29437. Convention date, Oct. 1, 1929. [Classes 97 (i) and 98 (ii).] Relates to the production of colour photographs on lenticular films. If a photograph is obtained on a film C and is then projected by light passing through it the axes of the " elementary beams " intersect at a point X the distance x of which from the film depends on the constants of the camera by which the photograph was taken. To secure correct colour rendering in the projected image the point X should lie in the colour filter of the projection apparatus so that the photograph could only be projected in an apparatus satisfying this condition. To enable projection to take place in any desired apparatus, the invention consists in producing from the original a copy I, the axes of the elementary beams from which will intersect at any desired distance y from the film, this distance being chosen to suit the apparatus in which the copy is afterwards to be projected. The films C, I are set up at a fixed distance apart and there is arranged between them a convergent optical system P<1> P<2> of focal length # by which the copy is produced. The points X, Y are conjugate with respect to the system P<1>, P<2>, so that by proper selection of # the desired value of y is obtained. The focal length of the system can be varied by adjusting the separation of its components.

Abstract: 1,244,675. Electrolytic meters. GENERAL ELECTRIC CO. July 28, 1969 [July 29, 1968], No.37741/69. Heading G1Q. A redox coulometer for use in timing applications is of the type providing a sudden change in voltage in a constant current circuit when a given quantity of current has passed through it and operates without the normal difficulties due to gas evolution or the deposition of particular amounts of solid material. The coulometer incorporates a container defining a chamber which is divided into two parts by an ion exchange membrane, each containing an electrolytic solution containing a redex couple. The membrane is impervious to the redex couple. A chemically inert electrode is positioned in contact with the solution in each part. A conductive lead contacts each electrode. The container is formed from two parts 13, 14 fitted together to define the chamber 12. This is divided in two by an ion exchange membrane 27 of sulphonated polystyrene, and each part contains a supporting electrolyte of 0À5M Na2 HPO4 and 0À5M KH2 PO4 containing a potassium ferrocyanide-ferricyanide redox couple. The inert electrodes 31 may be porous carbon or pyrolytic graphite, with platinum leads 23. As a constant current is passed through the coulometer, the ratio of oxidized to reduced material in each part varies, and the potential across the unit varies. If one of the oxidized or reduced materials is in limited supply, a large change in potential will occur when it disappears and this change can be used to trigger an external circuit, to indicate the conclusion of a timed period and initiate a reversed direction of current flow through the cell, to start a reset period. The reset period may be made different to the timing period by changing the current supplied.
