Title: Cementable femoral part of a hip joint endoprosthesis
Inventor: SCHELHAS KLAUS-DIETER
IPC: A61F2/36
Filed: 1988-06-11
Abstract: There is specified a cementable femoral part of a hip joint endoprosthesis with a stem that tapers toward the distal end and whose cross-section is designed mirror-symmetrically to a medial-lateral plane, with a flange-like supporting collar at the upper stem end, a pin formed on the supporting collar and a spherical head that can be attached to the supporting collar or is firmly formed thereon, and with several longitudinal grooves in the proximal half of the stem extending without undercut in the longitudinal direction of the stem. In order to ensure improved strength of the bone/cement/prosthesis connection the cross-section of the stem is delimited dorsally and ventrally by a straight section, whose extension intersects the median-lateral plane of symmetry at an acute angle, in the region of the proximal stem half. Moreover, the longitudinal grooves start with a predetermined depth below the supporting collar and end with a reduced depth distally, and form undercuts in the stem cross-section.
Patent DE-3824332-A1 (DE)
Title: Method of cooling hydraulic fluid in a supply tank and associated cooling arrangement
Inventor: SCHEURLEN JERG DIPL ING
IPC: F15B21/0423
Filed: 1988-07-18
Abstract: The present invention relates to a method of cooling hydraulic fluid (5), in particular in a so-called electrohydraulic compact drive (1). The hydraulic fluid reaching various hydraulic-fluid consumers (10, 11) from a supply tank (2) via a pump (6) must be returned at elevated temperature into the supply tank (2) via feedback lines (28, 30, 32). To improve the cooling across the outer walls of the supply tank (2), the returned hydraulic fluid (5) is sprayed into the supply tank (2) through nozzle openings (29, 31, 33) under the level of the hydraulic fluid (5) in such a way that convective flow loops form which in particular guide the heated cooling fluid along the walls of the supply tank and thus help to cool it. Partial flows of especially high temperature can be sprayed in near the wall area of the supply tank (2). As a result, the temperature of the hydraulic fluid (5) in the entire system can be reduced, which prolongs the service life and increases the operational reliability. <IMAGE>

Title: Roof having a concrete ceiling and roof rafters arranged thereon
Inventor: OSTERMAIR JOSEF DIPL ING
IPC: E04B7/20
Filed: 1988-09-09
Abstract: Provided on the underside of the roof, which, in particular, may be pitched, is a bottom shuttering (3) on which the roof rafters (5) are mounted by means of spacers (7). In this arrangement, the spacers (7) are introduced from the outset into the roof rafters (5). The spacers (7) are also concreted into the concrete ceiling (11).
