Abstract: L'invention concerne un dispositif d'ancrage (41) fileté à insérer destiné à être utilisé dans les dalles en béton coulé pourvu d'un platelage métallique ou d'un coffrage en bois. Ledit dispositif confère une certaine stabilité au platelage métallique ou au coffrage en bois, avant le coulage du béton. Une fois pris dans la dalle en béton (61), le dispositif d'ancrage (41) fileté à insérer constitue un élément de fixation pratique pour les tiges de support portant les crémaillères nécessaires, la tuyauterie et les systèmes de grille du plafond du bâtiment. Chaque dispositif d'ancrage (41) fileté à insérer peut accepter des tiges ou des boulons de deux tailles différentes et à filetages différents. Les ouvertures (63, 65) internes filetées sont protégées contre l'intrusion de béton lors du coulage par un manchon (53) plastique ou métallique. En outre, les dispositifs d'ancrage selon l'invention sont conçus de manière que la mousse ignifuge ou mousse isolante pulvérisée ensuite sur le plafond ne pénètre pas dans les ouvertures filetées, et n'empêche donc pas l'introduction des tiges de support.

Abstract: A nut fastener is formed with anti-cross threading features that include a rounded or chamfered edge at the entry end to the nut, followed by an unthreaded cylindrical counterbore that extends axially from the entry end to the threaded section of the bore. The rounded or chamfered entry end prevents cross threading and the unthreaded section is of sufficient length to ensure substantially collinear alignment between the threaded fastener and the correspondingly threaded nut before threaded engagement occurs. An optional radiused portion is formed between the unthreaded and threaded sections of the nut to further prevent cross threading. In a preferred embodiment, the anti-cross threading nut is a weld nut formed with weld protrusions which enable the nut to be welded to a large structural member before mating engagement with a threaded fastener occurs.

Title: Apparatus for processing thermoplastic synthetic plastic material
Inventor: BACHER HELMUT
IPC: B29C48/38
Filed: 2003-01-07
Granted: 2008-03-18
Abstract: An apparatus is provided for processing thermoplastic synthetic plastic material which is to be recycled. Within each of two receptacles, tools are fixed to disc-shaped tool carriers disposed one above the other. In each receptacle temperature sensors are provided for each level of circulating tool. The synthetic plastic material to be recycled is continuously under vacuum from its introduction into the first receptacle until its conveying off the second receptacle by a screw, thereby avoiding any damaging atmospheric influences. By means of the tools circulating at different levels within each receptacle, a sufficient dwell time is obtained for material within each receptacle, which contributes substantially to a homogeneous working up of the material. The temperature sensors allow overheating of the processed material and therefore thermal damage to be avoided.

Abstract: An apparatus and method to measure the position of a portion of a pump assembly within a well particularly for use in an oil or gas well and for downhole pumps driven by a drive shaft running from a surface motor. The apparatus comprises at least one measurement device which senses the position of a portion of a pump assembly downhole. The information can be used to position a rotor of the pump assembly at an optimum position relative to a pump housing of the pump assembly to produce fluids from the well at an increased rate. Where two measurement devices are provided, they can count the number of revolutions of the drive shaft of the pump assembly at two spaced apart points. The strain or torsion within the drive shaft can then be calculated. If the torsion within the drive shaft approaches critical levels the speed of its rotation can be slowed in order to reduce the torsional strain in the drive shaft. The method and apparatus thus reduce the number of failures caused by fractured drive shafts. Since the torsion within the drive shafts can be determined, the speed of rotation of the drive shaft can be increased in normal operating conditions which allows an increased production rate from the well.
