Title: An improved system of and apparatus for the telegraphic or telephonic transmission and reception of messages
IPC: H04K1/06
Filed: 1928-03-29
Abstract: 299,355. Prior, W. Oct. 24, 1927. [Convention date]. Void [Published under Sect. 91 of the Acts]. Perforated strip transmitters; secret telegraphy. -Cable code signals are stored in condensers at a telegraph transmitting station, and sent out in irregular order, and are re-arranged in the original order after storage in condensers at the receiving station. The system is stated to be applicable also to telephony and wireless signalling. At the transmitter the fingers 12 make contact through perforations in a tape (not shown), with the segments of a cylindrical commutator 7, pins 17 on the commutator engaging the guide holes in the tape. All segments numbered 1 in the diagram are connected to the slip-ring 1 and so to one plate of the condenser 1, the other plate of which is earthed, and the parts numbered 2 - - 6 are similarly connected together. The segments of the first and third 6-segment groups are numbered consecutively, while those of the second and fourth groups are numbered in the irregular order 2, 1, 4, 3, 6, 5. Positive and negative impulses are therefore stored in the condensers through the brushes 12 in one order and discharged to line through the brush 13 in Mother order. A similar arrangement is adopted at the receiving station (Fig. 3, not shown), for restoring the correct order of the signals; a recorder is connected to the brush 13, the line is connected to a brush 12 and the tape is omitted.

Title: Improvements in or relating to the measurement of the electrical conductance of liquids
IPC: G01N27/02

Abstract: 761,903. Measuring liquid conductivity. WAYNE KERR LABORATORIES, Ltd., and CALVERT, R. April 4, 1955 [April 2, 1954], No. 9686/54. Class 37. Apparatus for measuring the electrical conductivity of a liquid comprises an inductive ratio arm bridge having two transformers which are of toroidal form and so mounted as a unit that when immersed in a liquid they would be coupled by the loop of liquid extending through and around the cores, the input transformer being energized from an A.C. source and having a winding connected in a circuit to apply a voltage across an adjustable impedance in series with a winding on the other transformer, the latter also having a winding connected to a detector. As shown, the secondary 12 of transformer 10 is coupled through a variable impedance, calibrated in terms of conductivity, with the primary 14 of a transformer 15 connected to a detector 17. Both transformers are of toroidal form and arranged coaxially in a potting material to provide a passage of uniform section through the transformer cores for the flow of the test liquid. In this way current is induced in the liquid and thus in the winding 14, and impedance 13 is adjusted to balance the induced currents in the winding and so obtain a measure of the conductivity.

Title: Process for preparing trifluoroacetyl chloride
Filed: 1964-03-09
Abstract: Trifluoroacetyl chloride is made by the liquid phase chlorination of fluoral (trifluoroacetaldehyde) in the presence of ultraviolet light. The preferred reaction temperature range is - 60 DEG  to - 20 DEG C., but higher temperatures may be used when operating under superatmospheric pressure.  The reaction is suitably carried out by passing the stoichiometrical amount or an excess of gaseous chlorine into liquid fluoral. An inert solvent, e.g. carbon tetrachloride, may be used.  Examples are provided.  The fluoral used as starting material can be prepared by reacting chloral with hydrogen fluoride.

Abstract: PURPOSE:To reduce a production cost by improving impregnation properties of resin and simplifying a manufacturing process, by pressing a side surface of a fiber bundle at the time of impregnation of the fiber bundle with molten resin. CONSTITUTION:When a fiber bundle 4 is fed continuously into a fiber passing path 14 of a head block 5 under a state where molten resin (a) is fed into a manifold 7, the molten resin (a) is stuck around the fiber bundle 4 and infiltrated into the fiber bundle 4. The fiber bundle 4 is pulled out downward through a die outlet 9a through a rotation and driving of a cooling roll 6. Hereupon, a pressurizing member 11 presses a side surface of the fiber bundle 4, in the molten resin (a). With this construction, the fiber bundle 4 is pressed and spread by the pressurizing member 11 and a contacting area between the fiber bundle 4 and molten resin (a) is increased. Simultaneously with the above the molten resin (a) existing around the fiber bundle 4 is pressed into the fiber bundle 4. With this pressing-in of the molten resin (a), air existing among fibers of the fiber bundle 4 is driven out and the molten resin (a) adheres to the circumference of fibril of the fiber bundle 4.
