Abstract: 444,582. Electric endosmose. INTERNATIONAL LATEX PROCESSES, Ltd., 10, Lefebvre Street, St. Peter's Port, Guernsey. Sept. 21, 1934, No. 27157. Convention date, Oct. 10, 1933. [Class 41] [See also Groups V and VIII] In a process of mechanically spreading, coating, extruding, &c. an aqueous dispersion of rubber &c. by means of a confining or shaping member, an electrical potential difference is maintained between the shaping member and the dispersion, the charge on the said member being similar in sign to the charge of the disperse phase of the dispersion. The potential difference produces an accumulation of water adjacent the shaping member which acts as a lubricant. As shown, a sheet of fabric 1 to be coated is passed over a roll 2 and under a spreader bar 3 which is insulated from the rest of the apparatus and is connected to the negative pole of a direct current supply when an alkaline dispersion is used. The positive pole is connected to the roll 2 by a lead 5. A wetting roll 7 is provided to moisten the fabric 1, preferably with an electrolyte solution. As modifications, the positive pole of the current supply may be connected to an electrode immersed in the dispersion 6 or to a roll making electrical contact with the surface of the material 1 after it has been moistened bv the roll 7. In the case of positively charged dispersions, such as acid latex, the electrical connections are reversed. Potentials up to 220 volts may be used. When coating a wire in an extrusion die the potential may be applied between the wire and the die, and for producing threads, sheets, &c. the die is insulated from the body of the machine and maintained at a negative potential. Specification 422,516, [Group VIII], is referred to.

Heading H4D. In a photo-electric altimeter comprising a light transmitter modulated at a frequency and a photo-electric receiver and wherein altitude is determined from a knowledge of transmitterreceiver separation and measurement of the angles of depression of transmitter and receiver, the correct functioning of the altimeter is checked by periodically interrupting the transmitted light during intervals much less than the operational intervals of the altimeter. In one embodiment mirrors direct a sample of the transmitted light into the receiver for ten milliseconds every second and causes a relay to actuate a visible signal, Fig. 1 (not shown); in an alternative arrangement the mirrors are dispensed with, an auxiliary photo-cell samples the transmitted light, the sample is chopped into ten-millisecond pulses once per second, and the chopped signal feeds a neon-lamp which excites the receiving photo-cell, Fig. 2 (not shown).

Filed: 1965-06-29
Abstract: 1,079,143. Electric meters; magnetometers. MULLARD Ltd. June 29, 1965, No. 27482/65. Headings G1N and G1Q. Two crystals with anisotropic magnetic properties constitute the armature of an electric meter or the movement of a magnetometer. The crystal 1 of Fig. 2 is of haematite and is effectively a weak permanent magnet whose polar axis is its 'easy' axis a 1 ; the crystal 2 is of siderite and has anisotropic susceptibility, with its 'easy' axis a 2  at right angles to a 1 . When the two crystals are suspended in a weak magnetic field, the axis a 1  lines up with the field H, But in stronger fields induced magnetism in crystal 2 causes its axis a 2  to tend to move into line with the field H. At equilibrium the deflection 6 is a measure of the field H: it is stated that # is proportional to H over a fairly large range Figs.4 and 6 (not shown). A magnetometer consists merely of the suspended crystals. A moving-magnet electric meter consists of the two suspended crystals as armature and means to convert the current or voltage to be measured into a magnetic field. A moving coil meter may use such a pair of crystals (but with their 'easy' axes parallel) in addition to the moving coil, in an armature Fig. 5 (not shown) in which the coil carries the current to be measured and the crystals provide restoring torque, the magnetic field H being that of a permanent magnet.

Title: Method for subsequently setting data receivers in a contrinuous  transmission of encoded data transmitted in binary code form
IPC: H04L9/18
Filed: 1962-07-17
Abstract: 1429469 Data transmission; ciphering R HELL 17 July 1962 [19 July 1961] 27507/62 Heading H4P A method for subsequently enabling data receivers in a continuous transmission of enciphered data transmitted in binary coded form, wherein, after periodic time intervals which are short in relation to the entire transmission time, a pre-arranged signal is sent out by the transmitter, the purpose of the signal is not to record a data element in the receivers but to cause a new and hitherto unused section of the cipher running-down period duration to be set both in the transmitter and in the receivers. The setting of a new cipher section in the transmitter and all the receivers may be continuously prepared by local switch clock mechanisms in periodic time intervals, and within these preparation periods the transmitter completes the setting of the new cipher section by transmitting the pre-arranged signal to all the receivers and restarts the cipher pulse production from their new starting position, the transmission of the ciphered data subsequently being continued. Apparatuses employing local time cycle mechanisms and functioning, respectively, as a facsimile and a teleprinter receiver are described with reference to Figs. 1, 2 (not shown). According to an alternative method described with reference to a teleprinter receiver (Fig. 3, not shown) the transmitter briefly interrupts the transmission of ciphered data and by transmitting a pre-arranged signal it commutates itself and the receivers participating in the transmission to the clear operational state, and the, by transmitting a specific group of letters in clear text, it effects for itself and for all the receivers including the newly participating one, the commutation to the encoded operational state, the setting of a new cipher section and the restarting of all cipher pulse generators, the transmission of encoded data subsequently being continued.

A further increase in the writing speed is obtained by heating the material to be dyed. As particularly described, a coloured original is scanned line by line to derive a plurality of colour separation signals which serve to electrooptically modulate respective scanning laser beams, or to sequentially modulate the same beam, the carrier being changed according to the particular separation signal being used. The laser beams may be amplitude modulated, or pulsed for varying durations in response to the separation signals. The or each carrier may be in the form of a roll, or a continuous strip, or, when a single laser beam is used, may comprise successive areas containing different dyes.
