Abstract: 1500571 Connecting formwork panels J MAIER 23 Jan 1975 [24 Jan 1974] 3048/75 Heading E1S Formwork panels having perpendicular edge flanges 6 are connected edge to edge by fastening members, e.g. bolts 7, each passing through and holding together adjacent flanges and each having a projection, e.g. a transverse pin 8, for maintaining a spacing between the flanges, the resulting gap being covered by a member 15 which may be separate or connected to one of the panels. Further projections (10), 11 are provided to each side of the projection 8 and spaced therefrom by the thickness of a flange 6, for holding the flanges; the latter have keyhole slots to receive the bolt with transverse pins, which is rotated after insertion to secure it. A further projection 12 spaced by the thicknes of two flanges from the projection 11 may hold the flanges in contact temporarily during stripping. Tapered transverse pins may be provided for connecting panels at an angle. The covering member 15, if a separate component, is formed as a flange on a web 13 which is held between the panel flanges 6 by the bolt 7 passing therethrough.

Abstract: A knife sharpener of the kind having a hollow scabbard or housing for a knife blade, and a blade sharpening device arranged to be engaged by the blade cutting edge as the blade is moved into and out of the housing. The sharpening device is mounted on the front end of a carrier member which has its rear end pivotally connected to the housing so that the front end can be swung towards and away from a top wall of the housing. A biasing spring urges the front end of the carrier towards the housing top wall. A reaction member is disposed between that housing top wall and the carrier member and is pivotally connected to the housing for movement about an axis which is parallel to the carrier pivot axis and is located between the ends of the reaction member. A rear end of the reaction member engages an upper surface of the carrier member at a location between the carrier pivot and the zone at which the biasing spring acts on the carrier member. The front ends of the carrier and reaction members are separated when a knife blade is inserted into the housing, but the engagement at their rear ends is maintained at all times.

Abstract: A hot water radiator intended mainly for heating domestic and office spaces. The radiator consists of two main components (10,20) with a first main duct (1) for introducing hot water and a second main duct (2) for removing cooled water as well as of a number of radiator ducts. The radiator ducts are formed and bounded by plane surfaces (11,21) and indentations (12-19,22,23) in the main components. These indentations are short both by comparison with the main ducts and with the distance between the main ducts. The main ducts with plane surfaces, indentations and main ducts can be produced by pressing or rolling plane metal sheets. The main components can be joined with one another by seam-welding and sportwelding. The hot water radiator is intended for connection (13,14) to a central heating system which supplies the heated water and removes the cooled water.

Abstract: A snap hook 41 comprising a bi- ended base portion 43, a blade portion 45, a re-entrant portion 50 and a latch portion 47 is disclosed. The blade 45 is integral with a first end of the base, through the re- entrant portion, thereby providing the snap hook with an aperture 51 intermediate the base and the blade. The aperture has a mouth 55 and two integrally formed lips 53. The aperture is adapted to receive a substantially cylindrical portion of a retainer 59 therein. The latch 47 is integral with the second end of the base and thereby provides the snap hook with a hook 63 at the junction thereof. A free end 65 of the blade and a free end 67 of the latch are in distal relation to the base. A relaxed condition for the snap hook (full lines Figure 1) is defined to be when the distal end 65 of the blade is above the distal end 67 of the latch, in relation to the base. A locked condition for the snap hook (phantom lines Figure 1) is defined to be when the distal end 65 of the blade is positioned beneath the distal end 67 of the latch, in relation to the base. The lips 53 are adapted to lockingly retain the above-mentioned substantially cylindrical portion of the retainer 59 while the snap hook is in the locked condition and the blade 45 is in biased engagement with the latch 47. A ring 97 is selectively permitted to be secured to or released from the hook 63 by manipulation of the blade 45. <IMAGE>

Abstract: A novel method is provided herein for making paper or paperboard with a higher dry strength than previously by adding to the fiber pulp suspension a smaller amount than previously of cationic, water-soluble starch and a synthetic retention agent. In addition, a filler can be added to the fiber pulp suspension. According to the invention, cationic, water-soluble starch is added to the fiber pulp suspension at only 0.02-1.5% (as calculated from the dry weight of the pulp) and the synthetic retention agent (which is selected from the group consisting of polyacrylamides, their derivatives and copolymers), is added at only 0.005-0.1%, (also as calculated from the dry weight of the pulp). The addition can be made either to a fiber pulp suspension which is substantially free from filler, or part of the retention agent may be added to the fiber pulp suspension before the adding of the filler, or a pre-treated filler may be added to the fiber pulp at some other stage.

Abstract: The metering system and method provides an electronic power meter for simultaneously producing digital pulse trains proportional to power and to VARS or Q. In the preferred embodiment, the metering system employs delta-minus-sigma modulation of the voltage signal which produces a modulated output signal used for gating the analog current signal, multiplying voltage and current. The product of voltage and current is then supplied to another delta-minus-sigma modulator (90), which serves as a convertor outputting a pulse train. The converter (90) produces separate pulse trains for each polarity of the power being measured. VARS or Q readings are produced by delaying the output of the modulator (30) by a selected amount to produce the necessary voltage lag, after which the delayed modulated signal is supplied to another multiplying gate. A second converter (90) is used to output VARS and Q. A metering method is also disclosed, as well as an offset compensation system (70, C1) for use with metering systems.
