Abstract: A power returnable tape rule has an improved connection between the outer end of the power spring and the inner end of the coilable rule blade provided by interengaging element thereon.  The rule blade has an elongated aperture adjacent its inner end with the margins of the blade defining the aperture including opposed inwardly extending finger portions.          The tongue is configured with spaced transversely extending shoulders facing in opposite directions, and it extends along the upper surface of the rule, downwardly into the aperture under the fingers and upwardly from the aperture and forwardly thereof along the upper surface of the rule blade.   The shoulders on the tongue of the spring abut the margins of the aperture adjacent the finger portions in either direction of relative longitudinal movement to limit such movement and retain the two elements in assembly.

Abstract: The invention relates to a military safety helmet with a cap resistant to bombardment and an internal band arrangement, connected firmly to the helmet cap at several points and comprised of an approximately horizontally encircling annular supporting band, a plurality of bands extending in a radiating manner from a central fastening piece on the top side of the helmet and bands for connecting the adjacent radiating bands. The internal band arrangement provides all-round impact damping, especially under the effect of shocks, and good ventilation since the bands have formed-on bosses pointing towards the inner face of the helmet cap.      Above the supporting band, fastening strips extends which have no bosses and the ends of which are connected firmly to the helmet cap in such a way that the band arrangement rests against the inner face of the helmet cap via the bosses. The radiating bands are approximately the width of the bosses, and the bosses are preferably designed as hollow cylinders.

Filed: 1991-01-25
Abstract: Abstract of the Disclosure An anchoring device for fastening cladding panels to walls of buildings has a flat band of an essentially  rectangular  cross-section  that  is provided with  spaced  holes  arranged  one  after another in a longitudinal direction. An upper end of the band is connected to a fastening part. A bolt that is inserted into one of the holes fastens the band to a fastening element that is attached to the cladding panel. The fastening element comprises a supporting member and an essentially parallel counter member.  The  supporting  member  and  the counter member are spaced at a distance over a portion of their respective longitudinal dimension whereby the distance corresponds at least to the thickness of the band. The band is inserted into the space between the supporting member and the counter member.  A section of the band is bent directly above the supporting member, whereby the supporting member serves as a bending edge.

Inventor: ARNOUT MICHEL
IPC: B23K7/00
Filed: 1991-02-21
Abstract: Le procédé consiste à former, à la sortie d'une buse de coupe, un jet central de liquide de coupe et, simultanément, un jet concentrique de gaz autour du jet central de liquide, le jet de gaz ayant une vitesse supérieure à la vitesse du jet de liquide. Typiquement, le liquide et le gaz ont la même composition, de préférence de l'oxygène. Ce procédé permet de conférer une meilleure cohérence au jet de liquide sur une distance plus grande à la sortie de la buse, et donc de permettre l'obtention de coupes plus rapides et plus soignées et/ou une souplesse d'utilisation accrue.

Abstract: WATER CUT MONITORING MEANS AND METHOD              (D#79,282-F) ABSTRACT            The present  invention is a water cut monitor which includes a settling tank in which a quantity of fluid from a producing well is accumulated.  The fluid is removed as a stream of fluid after a predetermined interval from the accumulation of the fluid by the settling tank so as to allow the accumulated fluid to separate into three phases: free water, water-continuous and oil-continuous.  The flow rat  of the stream of fluid is measured and a  corresponding  flow  rate  signal  is  provided  as  well  as  a temperature signal corresponding to a sensed temperature of the stream of fluid.  The water cut monitor includes a plurality of electrodes  in contact with the  fluid.   Injection electronics connected to at least one of the electrodes provides an injection voltage and injection current to the fluid stream and also provides signals  corresponding to the  injection voltage  and  injection current.   A voltage  in  the  fluid  stream  is measured  and  a measurement signal provided.  A computer determines the water cut of the petroleum stream in accordance with the temperature signal, the injection voltage and injection current signals, the electrical phase angle signal and the measured voltage signal.     rgg79282.APP

Abstract: Absorbent products for absorbing body fluids which are worn in conjunction with an undergarment are disclosed.      The absorbent product comprises an absorbent core having a body facing surface, a garment facing surface and longitudinal edges. The absorbent products of the present invention utilize semi-rigid clip means far retaining the absorbent product with respect to the undergarment. Most preferably, such clip means are disposed on the garment facing surface and approximately at each lateral edge of the absorbent core. Twisting and other undesirable movement of the pad is thus reduced by a portion of the undergarment being retained between the semi-rigid clip means and the garment facing surface. Numerous alternate embodiments of clip means which grip the garment edge, as well as those which extend transversely across the garment facing surface are disclosed.
