Abstract: Packaging is disclosed for electrical installation equipment, in particular, made from a folded cardboard box, with two parallel first cardboard portions which form a front and a rear wall of the packaging and with two second cardboard faces extending perpendicular thereto, of which the cardboard face forms the bottom wall and the cardboard face forms the upper wall, with first flaps formed on the longitudinal edges of the front and rear wall and the bottom wall, which are attached to the longitudinal edges and able to be bent towards one another, so that they are in a single plane, with cover flaps attached to the edges of the upper wall extending in line with the longitudinal edges and which cover the first flaps and are bonded thereto, and with a third flap arranged on the upper wall which terminates on the edge of the upper wall opposing the front wall and is bonded from inside against the inner face of the front wall.

Abstract: A volume-adjusting insert for sample vessels comprises an elongated body with a septum seal on one end and a seal surface on the outside of the body. A through-chamber in the body provides a receiving chamber for a hypodermic needle inserted into the septum. The seal surface of the insert defines a reduced-volume sample chamber comprising the through-chamber and the vessel chamber portion of the sample vessel below the insert, or alternatively, below the seal surface. Sample fluid injected into, or withdrawn from, the insert communicates with the through-chamber and the lower vessel chamber. The device is particularly useful in converting multi-well microplates to low sample-volume vessels for automated sampling and testing, and allows the hydraulic pressure generated by a hypodermic needle to transport the sample fluid through the sample vessel and out of a bottom-extraction element.

Abstract: A telescopic boom (1) for a vehicle (25) or a hoist with a storage rack (6) for at least two box girders (2, 3) guided displaceably in one another in the direction of their longitudinal axes, which are mounted to pivot about a horizontal pivot axle (5) in the storage rack (6) and which can be displaced reciprocally by means of a servo-drive (19) is described. In order to create advantageous structural conditions it is proposed that the longitudinal axles of the box girders (2, 3) form an upwards arched arc of a circle (4) which runs concentrically to a common axis parallel to the pivot axis (5).

Abstract: Self-washing injection apparatus [101] for liquid chromatography injection valves utilizes an interior chamber [105] with a penetrable seal [109] at the top end of the chamber and a needle sleeve seal [113] at the bottom end of the interior chamber. A wash port [145] in the body [103] of the apparatus connects one or more sources of wash fluid to the interior chamber between the penetrable seal and the sleeve seal. The apparatus provides a simple and effective means to aspirate or pump wash fluids from one or more wash fluid reservoirs through the apparatus, the injection port of the injection valve, and associated components.

Abstract: A loading device for containers (C) comprises a pair of loading units (2), each having a telescopic column (4) supported on a bracket (3) so as to be swivelled about a common swivel axis (I). The telescopic column consists of a lower portion (9), an upper portion (11) and a column cylinder (17) moving the upper portion (11) with respect to the lower portion (9). Actuating cylinders (5) are connected to the lower portion (9) on both sides, and the upper portion (11) accommodates an extension arm (14) which can be swivelled about a swivel axis (III) parallel to the swivel axis (I) of the telescopic column. To expand the loading possibilities, the upper portion (11) carries a column head (12) which forms a slot-shaped swivel guide (18) with cam tracks (19) limiting the swivelling of the extension arm (14).

Abstract: A pneumatic hammer comprises a rigid unit of construction, which comprises a housing, a handle, an operating cylinder resiliently supported in the housing, and a tool holder for receiving a tool movable in a striking direction by the operating cylinder. The operating cylinder is axially movable in the housing relative to the tool holder. Compressed air is supplied to the operating cylinder, and a damping spring acts upon the tool holder in a direction opposite to the striking direction.

Abstract: A loading device for containers comprises a pair of like loading units to be mounted on a vehicle frame having a longitudinally extending center axis.

Abstract: A surgical instrument capable of being used to guide a thread inside a body and to cut the thread comprises a forceps jaw having first and second opposed surfaces each provided with a serrated portion and a cutting portion.

Abstract: An instrument for holding and chipping a bond has a pair of elongated curved handles spaced apart at one end, and pivotally connected at other ends to ends of flat elongated jaws. Central portions of the jaws are pivotally connected together. Outer ends of the jaws and handles normally flare outwardly and are held by outwardly biased leaf springs secured to the handles. The handles pivot on a free floating disk disposed in slots formed in facting edges of the handles. The outer ends of the jaws are formed with interfitting teeth and recessed having side walls formed with sharp cutting edges.
