Abstract: ABSTRACT OF THE INVENTION A tuned circuit is provided for connection to a transmitter  of  a  power  line  communication  system.  The tuned circuit comprises components selected to provide a low impedance path to ground for a power line communication signal of a preselected frequency.  When the transmitter is not in the process of transmitting a power line communica-tion signal, it causes a shorting switch to be closed which shorts a secondary winding of a transformer of the tuned circuit.   Therefore,  during  periods  of  time  when  the transmitter is not transmitting power line communication signals, spurious signals on the power line are diverted to ground and not permitted to travel  to remote receivers connected to the power line distribution system.

Abstract: FASTENER DRIVING TOOL             Abstract of the Disclosure A fastener driving tool of the type utilizing a motor driven energy storing flywheel and a recipro-cating fastener driving ram employs a flywheel having a metal peripheral surface that selectively engages a metal surface of the ram in order to drive the ram into engagement with a fastener to be driven into a workpiece.  An elastic cord returns the ram to a retracted position when the ram is disengaged by the flywheel, and a pair of elastic bumpers are employed to limit the travel of the ram in the direction of the retracted position and the direction of the fastener engaging position.  The ram, bumpers and cords form a subassembly that permits the ram, cord and bumpers to be removed from the fastener as a unit.          The cord is made relatively long to reduce the amount of stretch per unit length applied to the cord thereby to increase the life of the cord.  The motor and fly-wheel may be rotated in opposite directions to reduce precessional forces.

Date Mar. 24, 1988.Method for cleansing gas from solid, liquid and/or gaseous contaminants, by bubbling the gas through a liquid bath (32), and by introducing the incoming gas into a distribution means (14) and causing the gas to pass in part-streams through a multiple of inlet orifices (64) located at progressively increasing depths beneath the surface (34) of the liquid (32). With increasing inlet pressure an increasing number of inlet orifices (64) are utilized for an increasing number of part-streams. The gas flow is passed from respective inlet orifices (64) through connecting means (24, 26, 28) to outlet orifices (31) located at a considerably higher height level (h) than corresponding inlet orifices (64). The gas flow is caused to flow out through venturi nozzles (28) and/or to strike against impinger or striking surfaces (39) with a minimum pressure drop corresponding to said height differential (h). In this way full operational pressure is immediately achieved, as soon as gas is passed out through any of the inlet orifices (64), and an intense mixing of gas and liquid as well as a high cleansing efficiency are guaranteed.

Abstract: The invention relates to a laminated tamper-evident structure which exhibits an irreversible colour change upon delamination. The structure includes a laminate of at least two layers (10,12) capable of generating a colour by a light interference and absorption phenomenon that requires direct and intimate contact between an adjacent two of the layers. The strength of attachment among the layers of the laminate is such that the laminate can be uniformly and reliably peeled apart at the interface between the adjacent two layers. An overlying flexible strip (14) of transparent or translucent material is adhered to the laminate to facilitate the peeling operation. Upon peeling apart the laminate, the generated colour is irreversibly lost, thus providing evidence that the structure has been tampered with. The structure can be incorporated into a variety of closable articles or products to provide evidence of opening or tampering.

Inventor: TEGLUND LARS
IPC: E03F7/00
Filed: 1979-11-19
Abstract: A liquid-plug-creating device includes a collection tank or basin into which liquid flows such as the outflow from sanitary appliances. From the outlet at the bottom of the tank a riser extends upwardly at an acute angle to the horizontal. At the opposite end from the tank outlet, the riser terminates in a bend which reverses the direction of flow through the riser into a downwardly extending vertical pipe. A U-shaped piece of pipe with a horizontal outlet is connected to the lower end of the vertical pipe and provides a special form of trap. When the tank and the riser are completely filled with liquid, any additional liquid added exceeding a minimum flow, causes a liquid seal to be formed in the piece of pipe at the lower end of the vertical pipe. The excess flow creates a vacuum in the vertical pipe which sucks the liquid through the riser out of the tank in the manner of a siphon. The liquid immerges from the device in the form of continuous plugs with high kinetic energy content. The device permits the use of small-diameter pipes in house drainage systems while assuring the required self-cleansing effect, even if water-conserving flush toilets are connected to the device. Other fields of application of the device are irrigation and the metering of liquids in batches.

Abstract: The invention concerns a cable with reinforcing elements 2 surrounding the cable core, which reinforcing elements consist of a number of thin fibres running parallel with each other. In order that pull forces will not have an adverse effect on the good bending properties of the cable core 1, and in particular in order that water-tightness in a longitudinal direction can be guaranteed, it is proposed that the reinforcing elements are constructed of a number of fibres sliding against each other which form a layer 6 which completely surrounds the cable core. The fibres are wound round the cable core 1 with a long travel and the layer 6 is placed between a lower 5 and an upper 7 casing layer of thermal adhesive. <IMAGE>

Abstract: Method and device for gasification of solid carbon- containing material in a circulating fluidized bed reactor. Particles are separated from the produced gases in at least two stages so that in the first stage mostly the coarser so-called circulating particles are separated, which are returned to the reactor, and in the second stage, fine carbon-containing dust which agglomerated at elevated temperature is separated and the obtained larger particles returned to the reactor in the return line together with the circulating particles.  One advantageously prevents the agglomerating particles from being attached to the walls of the tube by leading the hot dust particles to the center of the tube and the circulating particles to the walls of the tube.
