Patent SE-7605608-L (SE)
Inventor: GUSTAFSSON A
IPC: F42D1/05
Filed: 1976-05-18
Abstract: A method and device for the initiating of a number of electrical detonators by a blasting machine of the type in which a capacitor is charged, the level of the charge being measured by level-sensing units and detonators are initiating by the electrical energy stored in the capacitor by firing after the charge level has reached a given level. The charge level of the capacitor is limited to a range which takes into account the variations of the load between different initiation moments such that the current impulse provided to each detonator assumes a value between a minimum and maximum limit. The limits for each individual load within the operating range of the apparatus is regulated in accordance with the electrical and physical characteristics of the detonators so that safe initiation and a disburance-free firing process are obtained.

Abstract: In a video signal processing system, apparatus for limiting excessive peak and average beam currents demanded by a kinescope in response to image representative video signals. A control signal derived by a sensing circuit in response to excessive beam current is applied to the kinescope in a manner to limit excessive beam currents above a threshold level. The sensing circuit includes a capacitor arranged with a conductive diode to form an average responding filter such that the sensing circuit derives a control voltage representative of excessive average beam current in a first beam current limiting mode. In a second beam limiting mode, when beam current exceeds a predetermined level, the diode is rendered nonconductive and the capacitor is decoupled for average detection purposes. In this mode, the control signal is free to vary in accordance with rapid variations in peak beam current.

Abstract: A continuous cellular glass manufacturing method is described. A mixture of ground glass and of one or more substances, such as coal dust, coke dust, graphite dust, one or more powdery and/or liquid and/or diluted hydrocarbons, one or more powdery and/or liquid and/or diluted carbohydrates, one or more hydrocarbons and/or their derivatives, one or more powdery and/or diluted carbonates, fine natural earth, ground natural stones, ground ceramics, cement, one or more powdery and/or dissolved soluble glass substances, water and other similar substances, is partly or totally solidified by drying and/or by reaction, letting it stand for at least 10 minutes. The mixture thus solidified is granulated and the glassy mass so obtained is distributed over a refractory wire conveyor belt or of refractory sheet, after spreading a separating substance in the conveyor belt which prevents the glassy mass from sticking to the conveyor belt. The vitreous mass is then transported by the conveyor belt through a furnace in which the vitreous mass melts, expands and partially or totally cools.

Abstract: A container closure comprising a cap and an annular ring connected to the cap by a bridge. The annular ring includes a laterally extending span or weakened portion having lesser tensile strength than the remainder of the ring. When the cap is rotated to loosen the cap, the annular ring is constricted radially inwardly, thereby abutting the container neck and frustrating removal until either the bridge or span is broken. A broken bridge or span indicates both visually and by touch that the closure has been tampered with. In a preferred embodiment, the cap and annular ring are integrally molded from plastic as a unitary structure.

Abstract: A manually disengageable centrifugal clutch for motor vehicles has a clutch cover fixed to a flywheel, a pressure plate axially movable relative to the flywheel, and an intermediate disc. An intermediate plate defines, together with the pressure plate, a plurality of outwardly narrowing spaces for radially movable centrifugal weights and is spring biased towards the pressure plate. The intermediate plate is suspended on disengagement arms and is movable thereby away from the pressure plate. In one position at a certain distance from the pressure plate, the spaces for the centrifugal weights are widened so much that the weights cannot exert any pressure on the pressure plate. The clutch is thereby disengaged regardless of rotational speed, the disengaging force only depending on the spring force on the intermediate plate.

Abstract: The temperature regulating unit of a heating system (H) is combined with a cascade circuit (22, 25, 39), operating in stages and as a function of load, for switching a plurality of heat generators (1a, 1b, K) on and off. It is suitable for multi-stage heat-pump operation (1a, 1b) in a bivalent heating system having a boiler (K) for fossil fuels as auxiliary heat generator. An integrator (18) integrates a temperature difference ( DELTA  theta ) between a desired and an actual value ( theta vs,  theta vj) with respect to time (t). A first threshold value switch (23) influenced by the integral regulates in each case one of the heat generators (1a, 1b, K), as a function of the heat requirement, in on/off operation, or an actuator (6, 7) in a quasi-continuous fashion as a pulse generator (24). Via a second threshold value switch (22) with a higher threshold value, the same integral controls the load-dependent switching on and off of the heat generators. The regulation and control system is suitable for low-temperature heating installations with flat heating curves, and also prevents the short-term switching on and off of the regulated heat generators (1a, 1b, K) under limiting conditions.

Abstract: Method for pressurized fluid stream treatment of the surface of a relatively moving substrate to impart visual surface changes thereto. A fluid discharge manifold having an elongate discharge slot disposed across the path of relative movement of the substrate discharges pressurized fluid, such as air, in one or more narrow discrete streams into the surface of a substrate, such as a textile fabric. In one embodiment, a plurality of spaced air outlets are disposed in the discharge slot of the manifold and pressurized cooler air is selectively directed through the outlets and across the slot in accordance with pattern information to block heated air streams from exiting from the discharge slot in selected locations and thus pattern the surface of a substrate comprised of thermoplastic yarns. The slot of the discharge manifold also may be provided with an elongate shim member having a plurality of spaced notches in a side edge of the shim member. The shim member is disposed with its notches in the discharge slot to provide corresponding spaced channels for discharge of the fluid in streams onto the substrate surface. The shim member may be employed alone in the manifold slot to pattern the moving substrate, or it may be employed in combination with the cooler air blocking outlets to provide more intricate patterning of the substrate.
