Abstract: A modulator stage of a switched vertical deflection amplifier produces pulse width modulated gating signals obtained by modulating horizontal rate pulses including a ramp portion at a vertical deflection rate. The gating signals control switches coupled between a source of horizontal retrace pulses and a capacitor for charging the capacitor with decreasing and increasing amounts of energy during respective first and second intervals during each vertical trace interval for producing a sawtooth current in a vertical deflection winding coupled to the capacitor. A generator adds a nonlinear component to the ramp portions of the horizontal rate pulses for altering the gain of the amplifier during the vertical trace interval for producing a scanning current with a desired degree of linearity.

Abstract: In manufacturing concrete tiles a stiff concrete mass is molded and heavily compacted by means of a rapidly rotating pressing roller on sheet metal molding trays, which during the molding operation are supported by carriers having relief-like supporting surfaces which are generally complementary to the bottom sides of the tiles. The tray carriers form parts of an endless conveyor passing a concrete extruding station, in which the pressing roller is included, the tray carriers being formed as platforms placed freely between a pair of driving chains, to which each platform is connected by one pair of coaxial pivots only. Each platform is composed of two segments, which are hingedly interconnected independently of the chains. When passing the concrete extruding station the tray carrying platforms rest on an endless intermediate belt moving over a stationary supporting bed, through the top side of which pressurized air is supplied in order to reduce the friction. The sheet metal trays are delivered to and removed from the conveyor platforms by means of loop-forming, flexible elements.

Abstract: A method and an apparatus for desalination and/or purification of water, comprising a buoyant enclosure having restricting side walls (2, 2') spanned by an upper wall (1). The enclosure is partly or completely immersed in water, the restricting side walls (2, 2') being arranged to suspend same floating on a water surface. The enclosure is provided with air inlets (5, 5'), and an air stream is forced by means of wind force, wave energy and/or solar energy through the enclosure to a cooler (8), from which the condensate is transferred to a storage tank (19) or similar. A second and lower wall surface is suspended floating adjacent to the water surface, but below same, arranged to absorb heat imposed by solar energy. The enclosure is advantageously arranged to partly cover a beach, washed by waves, to obtain an increased evaporization. By arranging the upper wall with a number of lense elements, incoming solar rays are concentrated to the surface to be heated. A solar heated stack is advantageously arranged connected to the air outlet from the cooler (8), thereby increasing the air flow rate within the enclosure. Rain water, collected on the outer surface of the upper wall, is diverted through a substantially centrally located outlet via a conduit to the storage tank (19) used for the condensate.

Abstract: A control system is provided for allowing complex shapes to be machined on a workpiece at high speed. The control system is computer (13) controlled and receives workpiece profile data which are converted into a succession of tool position signals during machining. Not all the digital signals are calculated at one time, a number of future digital signals are calculated during a succession of time intervals. In each time interval, a tool position signal is outputted which is of a constant amplitude corresponding to the required tool position and which is fed to a signal processor (19) where it is converted into a continuous signal which so changes progressively that at successive time intervals, equal to the time intervals of the tool position signals, the amplitude of the continuous signal is related to the successive values of the tool position signals. This continuous signal is fed to a closed-loop control system (22) which controls the movement of the tool holder in accordance with the continuous signal. The tool holder is of a type having a bandwidth sufficient to allow the required movements at the required speed. The control system has proportional and differential feedback (24, 25).

Abstract: The mirroring surface forms an acute angle to the main plane of the front glass so that an essential part of the light reaching that plane is reflected in a direction parallel to it. The light source emits a beam towards the reflecting surface so that after reflection it is directed towards the front glass, and the surface is concave in at least specific parallel cross-sections. The light emitted from the source is coloured, not white. An alternative form is for the front glass to be directly lit by the source, i.e. withuot the major part of the light firstly being reflected by the mirroring surface. Also, it is possible to use twin angled mirrors widening outwards in V-formation from the front glass, allowing the front glass to be lit directly by one source, or indirectly by two light sources.

Abstract: A fabric softening and antistatic liquid laundry detergent composition includes synthetic anionic organic detergent, bentonite and higher aliphatic isostearamide antistat in an aqueous medium. The liquid detergent composition preferably contains a builder, such as polyphosphate and/or carbonate. A process for washing and drying laundry utilizes the described liquid detergent in the washing operation and produces laundry that is soft and static-free, or of low electrostatic charge, despite having been subjected to a tumble drying process or similar static charging drying process, which normally causes laundry of similar fabrics to become electrostatically charged, resulting in objectionable "static cling". A combined softening and antistatic composition which comprises bentonite fabric softener and N-isostearamide antistat in an aqueous medium is intended for addition to liquid detergent compositions or to wash waters. The preferred isostearamides are N-cocoisostearamide, N-octylisostearamide and N-hydrogenated tallow isostearamide.

Abstract: A process for increasing the process temperature of an air compressing internal combustion engine includes mixing exhaust gas with the intake air. The amount of exhaust gas to be recirculated is set with reference to speed and load. To achieve an increased process temperature within a short period and with unrestricted internal combustion engine power, the intake air is preheated, taking into account a predetermined limit temperature of the coolant, when the engine is operating between a lower and upper speed range at 90% useful power. The intake air is also preheated in a subsequent speed range, extending up to 90% of the nominal engine speed, at 75% useful power of the engine. Exhaust gas is mixed in with the intake air between a medium to upper speed range and up to 75% of the useful power. The recirculated stream of exhaust gas is reduced, depending on the vehicle velocity and the percentage of useful power.
