Filed: 1970-03-26
Abstract: 1276289 Holography INTERNATIONAL BUSINESS MACHINES CORP 26 March 1970 [3 April 1969] 14656/70 Heading G2J [Also in Division G4] In a data storage system, a plurality of information words can be represented in succession in an information beam of radiation which is interfered with a reference beam to form an interference pattern which is recorded at a pre-selected position on a recording surface, a stored word being retrieved by irradiating the corresponding recorded interference pattern with a reference beam of radiation. In Fig.1, a light source 4 via a beamsplitter 6, mirrors 8, 9, an expander lens 10 and a column of lenses 11, produces a column of light beams 13 each of which is passed or blocked by a respective Kerr cell at 14 depending on the value of a respective bit in a word to be stored. The beams passed are diffused at 15 to form an information beam 13 which is applied with a reference beam 7b through an aperture 3 in a mask 2 to interfere holographically on the photographic surface of a storage drum 1. Other words can be stored at other positions on the drum by rotating the drum and/or moving an optical system 16a, b, c (through which the reference beam 7b is applied from beam-splitter 6) vertically using a rack and pinion 17, the mask 2 also being moved vertically in the latter case. Read-out, Fig.3 (not shown) uses a selectively-energizable light source and a column of photo-cells, for each circumferential track of the drum, the drum being rotated to bring successive word patterns into the sensing position. Each column of photo-cells feeds a respective buffer, timed by signals sensed photo-electrically from a timing track on the drum. Different sequences and combinations of the light sources can be energized to read-out any desired combinations of words in parallel.

Title: Dihydrazide-formaldehyde condensates suitable for treating textiles
IPC: C08G12/04
Filed: 1958-05-09
Abstract: Condensation products formed at pH 6-11 of 4-20 mols of formaldehyde with 1 mol of a dihydrazide R(CONHNH2)2 are soluble in water and useful, as a 4-20% solution, for impregnating cellulosic textiles. R=(CH2)n, where n=0, 1, 2, 3, 4 or 5.  The textile treating bath may include a catalyst, e.g. magnesium chloride; aluminium chloride, formate or tartrate; p-toluene sulphonic acid or a salt thereof with ammonia or an amine; methylamine or piperidine hydrochloride. Impregnation is followed by drying and heating to cure the resin. Examples describe the following condensates adipic, succinic glutaric or oxalic acid dihydrazide and formaldehyde.ALSO:Cellulosic textiles are rendered resistant to creasing by impregnation with an aqueous solution containing at least 4% by weight of a reaction product of formaldehyde and a dihydrazide of an aliphatic dicarboxylic acid (see Group IV (a)).  A catalyst for curing the aldehyde condensate may be included in the solution. The impregnated textile is dried and heated to cure the resin. The cloth may then be finished by conventional procedures.  In Example 1 Indian Head cotton is treated with a condensate from adipic acid dihydrazide and formaldehyde, with magnesium chloride hexahydrate as a curing catalyst.  Other examples are similar employing the dihydrazides of succinic, glutaric and oxalic acids. Figures are given for some physical properties of the treated fabrics.

Title: Method and apparatus for locating ruptured nuclear fuel elements
IPC: G21C17/04
Filed: 1961-04-26
Abstract: 915,339. Nuclear reactors. GENERAL NUCLEAR ENGINEERING CORPORATION. April 26, 1961 [May 2, 1960], No. 15049/61. Class 39 (4). A method for locating a ruptured fuel element in the core of a nuclear reactor comprises sequentially increasing the power output of confined areas of the core, measuring the radioactivity of the reactor effluent while sequentially increasing the power, and determining the relative changes in the level of radioactivity incident to the sequential increase in power output, the area within which the greatest change occurs being the area containing the ruptured fuel element. In the boiling water reactor shown diagrammatically in Fig. 1 the fuel elements are arranged in clusters centred round tubes 46 (of which only one is shown). A storage tube 48 is arranged above each tube 46, and balls 47, either of fuel or of neutron absorbent material, can be maintained in the tube 48 by a fluid jet supplied from a jet tube 56 or allowed to fall into the tube 46. Each jet tube is connected to a manifold 52 by a valve 58, and valves 58 are opened (when the balls 47 are neutron absorbent) or closed (when the balls 47 are fuel) in sequence to cause the power to increase in each fuel cluster in sequence; an increase in the radioactivity of the reactor effluent when the power in a cluster is increased indicates a faulty fuel element in that cluster. The power in a fuel cluster may first be decreased before the increase. If the balls 47 are neutron-absorbent the fluid jet may be of cold water, which will also increase the power by its increased moderating effect; in fact the balls may be omitted and the power increased solely by introducing water into the tube 46. In the reactor shown steam passes out of the reactor to a turbine 22 and condenser 26, and the gas exhausted from the condenser is monitored in unit 60 which may be a scintillation counter. Specification 915,338 is referred to.

Title: Improvements in or relating to automatic telegraphy
IPC: H04L15/18
Filed: 1922-06-01
Abstract: 202,759. Heurtley, E. S., and Muirhead & Co., Ltd. June 1, 1922. Automatic telegraphs.-In an automatic transmitter employing perforated strip, the peckeroperated contact mechanism maintains contact made either for a positive or negative signalling impulse until a space or a marking contact of opposite polarity intervenes. The block signals may be broken up into beat signals, one for each time unit, by means driven in synchronism with the pecker-operated mechanism. The strip is fed in the usual manner by a motor driving a star wheel c<1> which engages the central perforations in the strip. Two peckers D (of which one only is shown) corresponding to the two rows of perforations of the strip are mounted on levers d pivoted at d<1> on the end of an arm of the rock ing-bar E rocked by means of a crank pin f on the shaft F. A large gear wheel G on the shaft C of the star-wheel c<1> gears with a small pinion f<1> on the shaft F so as to turn it one revolutior for each tenth of a revolution of the star-wheel c<1> which has ten teeth. The end d' of each lever ( is turned into the horizontal. Each contact lever H works between two contacts J and carries two arms K. The lever d is moved once for each step of the strip, and, according as the pecker I is or is not allowed to rise by' a perforation in th( tape, the end d<2> contacts with the lower or upper arm K to move the contact lever H against its corresponding contact where it is held, until posi tively moved, by a bias member h' and a spring h<2>. In a make and break mechanism to trans form these block signals into beat signals, a rock ing contact-lever L is pivoted on an adjustable support M, and its lower end meets a contact m<2>. The contact of the lever L is intermittently broken by means of a cam N on a shaft n, a pinion wheel n<1> on which is driven by the gear wheel G and makes one revolution for each step of the strip. The length of contact for each revolution may be adjusted by means of a pointer n<2> which is set against an indication on a scale O, and the support M of the lever L is adjusted until the lever just makes contact at m<2> wher the other end meets the cam. If both levers H are simultaneously on their marking contacts, the line is arranged to be earthed. If transmission is by means of relays, the marking contacts J, Fig. 1, of the two levers H are connected to opposite sides of two relay coils P, the armatures p of which move between contacts p<1>, one armature being earthed and the other connected to line, the upper and lower contacts being connected to opposite ends of a battery Q. If transmission is not effected by means of relays, the lever L is connected to line. and plays between two contacts one earthed and connected to an earthed contact lever H and the other connected to the second lever H. The marking and spacing contacts J are connected to opposite ends of a battery.
