Patent SE-7712318-L (SE)
IPC: B01D35/143
Filed: 1977-11-01
Abstract: A differential fluid pressure indicating device for use in conjunction with a filter body carrying a filter element which provides an exteriorly visible signal when the differential pressure across the filter element exceeds a predetermined amount. The device comprises a housing having a cylindrical chamber in which a rotationally constrained piston is axially slidably disposed and movable between a first and second axial position while resilient means urge the piston towards its first axial position. The inlet fluid pressure communicates with one axial end of the piston while the outlet fluid pressure communicates with the other axial end of the piston. When the differential pressure across the filter element exceeds a predetermined value, the inlet fluid pressure moves the piston from its first to its second axial position and releases a spring loaded exteriorly visible member which rotates from a first to a second rotational position.

Abstract: A circuit is described for protecting a semiconductor junction device such as a transistor against damage from high voltage transients that can be produced by kinescope arcing in a television receiver. The protected device is coupled to a circuit point at which the transients can appear. The protection circuit comprises a normally nonconductive protection transistor with a collector coupled to a source of operating potential, a base coupled to a source of threshold conduction bias reference voltage, and an emitter connected to the circuit point at which high voltage transients are likely to appear. The base bias of the protection transistor is determinable independent of the bias of the protected device, and the protection circuit is connected to the protected device with substantially zero voltage offset between the circuit point and the protected device. The protection transistor conducts in response to transient voltages appearing at the circuit point above a threshold level, and provides a path for safely diverting potentially destructive transient current away from the protected device.

Abstract: In each case two printed products conjointly travel through a processing path which starts at an input or infeed section and terminates at a removal or withdrawal section. At the infeed section an opening is produced in one of these printed products by the action of a pressure element which exerts a pressure or force transversely with respect to the plane of the printed products. During the forward advance of the printed products in a subsequently arranged feed section the opened printed product travels onto a separation element, such as a separation wedge, by means of which such printed product is opened. There is stuffed an insert into the opened printed product. At this first feed section the other printed product, which up to this time merely travelled along, is opened by means of a further pressure element. During the further advance of the printed products the second printed product is likewise opened by a separation element, for instance a separation wedge, which engages into the previously formed opening of this other printed product. At a second feed section there is now likewise stuffed an insert into the open second printed product. The final products, each of which have been provided with a respective insert, are now removed from the removal section for further processing. With a given processing speed the output of the equipment is increased due to the simultaneous travel or passage of two printed products through the stuffing device.

Abstract: The invention relates to a method and an arrangement intended for measuring the temperature of molten metal 5 in a vessel 4 provided with a lining 6. A light guide 1 of a transparent, heat resistant and corrosion resistant material is passed through the lining 6 and consists of a narrow part in the form of a rod and a broad part 3 with a flat end, where the wide part 3 acts as an optical cavity, radiating essentially as a black body with the temperature of the molten metal, which transmits radiation to a pyrometer 7 via the narrow part. The quotient between the cross-sectional area of the narrow part and the lateral surface area of the wide part 3 facing the molten metal does not exceed 0.5. According to the method, this light guide 1 is mounted in a zone in the vessel 4 where the molten metal 5 has maximal circulation caused by convection and at a depth h that is not less that the sum of the thickness t of the lining 6 and a value that is equal to half the maximal transverse dimension d of the wide part 3 of the light guide. <IMAGE>

Abstract: A belt clamp for vehicle safety belt systems comprises a fixed clamping jaw mounted on a frame and a movable clamping jaw engaged by the belt and carried by the frame in a manner such that it moves toward the fixed clamping jaw in response to tension in the belt. Spacers on the frame limit the extent of movement of the movable clamping jaw toward the fixed clamping jaw. A deformable member interposed between the fixed clamping jaw and the frame deforms in response to a predetermined tensile load on the belt so that the belt is allowed to slip through the clamping jaws and absorb the kinetic energy of the occupant.

Abstract: An isostatic press acts against a moulding tool (4,5,11,12,32,33) enclosed in the pressing chamber of the press, the cavity (4) of the press tool being defined in the press by an enveloping wall (5) of an elastomeric material and two end walls (11, 33) meeting the enveloping wall (5). The dry pressing chamber of the press is defined by a radially deformable elastomeric jacket (6) exercising press pressure against the enveloping wall (5) of the moulding tool, and two press end structures (2,3) meeting the pressing chamber jacket (6) and carrying the end walls (33, 11) of the moulding tool. At least one end wall (33, 11) is carried by an adjacent end structure (3, 2) via an elastomeric element (31). The elastomeric element is disposed with its peripheral edge exposed against, and lying adjacent the deformable elastomeric jacket (6) of the pressing chamber. When the press is pressurized, the jacket (6) will press radially against the elastometic element (31) such that the latter is axially expanded, thereby compensating for the axial strain of the press frame.

Abstract: A continuous machine for the manufacture of fiber-containing materials such as paper, which comprises a rotating cylinder partly immersed in a body of liquid containing fibers in suspension. The surface of the cylinder comprises permeable and impermeable areas arranged in a predetermined pattern, and fibers are drawn onto the permeable areas by suction from within the cylinder, the layers of fibers formed on these areas being transferred to a conveyor belt which contacts the cylinder surface at a zone out of contact with the liquid. The surface of the cylinder is washed upstream of the transfer zone to remove fibers and other particles which may adhere to the impermeable areas of the cylinder surface by feeding cleansing liquid, such as pure water, across an overflow edge into a space adjacent the cylinder so that the cleansing liquid flows parallel to the impermeable areas.

Abstract: An apparatus is provided for supplying for a subsequent process step a desired number of flat sheets at one time from a pile of flat sheets such as pulp sheets or the like. The pile is put on a platform which is elevated step by step by a given amount corresponding to a desired number of sheets. A gap is first formed in the pile by inserting one wedge member which is provided so as to be reciprocatingly movable in the transverse direction with respect to the pile. By also inserting in the gap fork tines provided so as to be likewise reciprocatingly movable in the transverse direction with respect to the pile, the flat sheets on and over the fork tines are assuredly separated from the others. At the same time these upper sheets are sent to a feed mechanism by virtue of the engagement of stopping members which are movable integrally with the fork tines in association with the forward movement of the fork tines and the edge portions of the flat sheets.
