Abstract: A hybrid liquid toner composed of a mixture of two different types of liquid toner. One type is a liquid toner that includes a complex amphipathic molecule of which at least a fixer and a dispersant are polymeric moieties and which additionally includes a charge director and optionally includes a color agent, all of these being carried by a volatile organic solvent of high electrical resistivity. The other type of liquid toner is one that includes a fixer and a dispersant as separate chemical entities and further includes a charge director, a pigment type color agent and a carrier solvent such as mentioned above. The two toners can be mixed in a very wide range of proportions and when so mixed have several advantages which makes the hybrid toner particularly useful in connection with preparation of lithographic masters and microfiche reproductions by electrostatography as well as useful as an all purpose liquid toner.

Abstract: A cord conductor of two insulated conductor strands has a female terminal molded at one end and a conventional plug at the other. The female terminal has a pair of female contacts positioned therein which are in permanent electrical connection with their associated conductor strands. The female terminal is provided with a pair of terminal openings therein, the openings being adapted to frictionally receive the prong from a duplex plug that is in electrical connection with an electrical appliance. When the prongs are frictionally positioned in the terminal openings they are in slidable engagement with the female contacts to complete a portion of an electrical circuit.The pair of terminal openings has a safety closure associated therewith. The safety closure is mounted between the terminal openings and is movable between a first and a second position.

Abstract: The present invention relates to vessels which are propelled by two or more groups of thrusters and particularly to ships or oil drilling rigs in which it is desired to keep on a particular station. In some circumstances one of the thrusters is found to interfere with the operation of another thruster or to be overloaded when another thruster is not overloaded. The invention provides a method and apparatus for alleviating these problems.

Abstract: A control device designed to be responsive to a change in the rate of flow of liquid in a flow line, for example milk in the flow line of an animal milking machine, between a relatively high value and a relatively low value, including a vessel through which the liquid is arranged to pass and in which it can attain different levels, and a control member movable in response to the change in volume of liquid in the vessel between a first position into which it is biased when the vessel is empty, and a second position into which it is arranged to move when the vessel is full, the vessel having in its lower part an aperture through which liquid can flow out of the vessel, and the arrangement, including the size of the aperture, being such that when the liquid flow rate changes from the relatively low to the relatively high value the vessel fills and the control member, which may be the vessel itself or a float, moves to its second position, and when the liquid flow rate changes from the relatively high to the rela

Abstract: Each section of an intermediate metal conduit with a constant diameter axial passageway has male pipe threads formed on its outer wall surface at one end. The other end of each conduit section has a short length of decreased outside diameter extending axially inwardly from the flat end face of the section, to form an external annular stop shoulder. A coupling sleeve has a pair of annular flanges which define central openings in mutual axial alignment but of different diameters such that the coupling sleeve may slide freely to a limited extent over the full external diameter of said other end of the conduit section. The coupling sleeve is retained captively on this other end by a resilent constrictable lock ring positioned in an annular lock ring groove disposed axially inwardly of the stop shoulder. When the coupling ring is unstressed, it protrudes, in part, radially outwardly of the groove and is in the path of movement of one of the flanges. The coupling sleeve can be retracted, i.e.

Abstract: A television transmission system of the kind in which some of the line scan periods of a conventional transmission that are left blank (as far as picture content is concerned) between successive frame transmissions are utilized for signalling data for selective display on the screen of a television receiver. The improvement over previous systems is that the information to be displayed as a line of data may be transmitted in a single line scan period. This is achieved by transmitting in a line scan period a page number and then in subsequent line scan periods the lines of data for that page. New page numbers are then transmitted followed by their respective lines of data in sequence. A receiver for the transmission system is described.

Abstract: A novel composition constituting a mixture of 1,3,5-tri (variegated alkanols) hexahydro-s-triazines and 1,3,5-trialkanol hexahydro-s-triazines, where the alkanol moieties have from 1 to 4 carbon atoms. The composition is made by reacting a mixture of monoalkanolamines, preferably in substantially equal gram-molecular proportions, with paraformaldehyde and stripping off the water formed by the reaction. The composition is used by adding a bactericidally or fungicidally effective amount thereof to a carrier which is to be protected against the activity of bacteria or fungi or which is to be applied to a substrate to be so protected. The carrier may be a solid medium, such as solid soap or a liquid medium such as liquid soap, water or an organic liquid, e.g. a liquid alcohol or a liquid hydrocarbon. Typical carriers are cutting oil, hydraulic fluid, varnish, shellac, water- and oil-based paints, methanol, ethanol and propanol, liquid adhesives, cleaners and disinfectants.

Abstract: A receiver for a television transmission system of the kind in which some of the line scan periods of a conventional transmission that are left blank (as far as picture content is concerned) between successive frame transmissions are utilized for signalling data for selective display on the screen of a television receiver. The information to be displayed as a line of data may be transmitted in a single line scan period. This is achieved by transmitting in a line scan period a page number and then in subsequent line scan periods the lines of data for that page. New page numbers are then transmitted followed by their respective lines of data in sequence. The receiver selects a desired page of data by identifying the desired transmitted page number and then recording all lines of information subsequent to that page number until it identifies a further page number whereupon it ceases to store any further information.

Abstract: A protective arrangement for a cooling system of the kind in which a fluid, which may be in the form of a liquid, gas, vapor or a two-phase fluid, is arranged to be circulated around the system under pressure, said protective arrangement comprising means for injecting into the system fluid under pressure for maintaining a flow in the normal direction through a region of the system, or for preventing cessation or reversal of flow through said region, for a period following a reduction in the pressure of the normal circulating fluid feeding said region, which may be due for example to a breach in a part of the system upstream from said region.

Abstract: A nuclear reactor containment vessel faced internally with a metal liner is provided with thermal insulation for the liner, comprising one or more layers of compressible material such as ceramic fiber, such as would be conventional in an advanced gas-cooled reactor and also a superposed layer of ceramic bricks or tiles in combination with retention means therefor, the retention means (comprising studs projecting from the liner, and bolts or nuts in threaded engagement with the studs) being themselves insulated from the vessel interior so that the coolant temperatures achieved in a High-Temperature Reactor or a Fast Reactor can be tolerated with the vessel.The layer(s) of compressible material is held under a degree of compression either by the ceramic bricks or tiles themselves or by cover plates held on the studs (in which case the bricks or tiles are preferably bedded on a yielding layer (for example of carbon fibers) rather than directly on the cover plates.
