Title: Device for tensioning driving belts, particularly for motor vehicles
Inventor: BREINDL WERNER
IPC: F16H7/12
Filed: 1989-05-10
Abstract: The invention relates to a device for tensioning driving belts, particularly for motor vehicles, with a cylinder/piston arrangement (6) arranged in an articulated manner, the free piston end of which exerts a pretension on the belt (1), guided on the V-belt pulley (2), via a connection bearing (7) on a lever-shaped mounting (4) arranged in an articulated manner and via a belt pulley (3). The piston/cylinder arrangement has a pressurised-fluid chamber (17) which serves to support the piston rod relative to the housing and is connected to a pressurised-fluid reservoir (20). In known devices of this kind, it is necessary to arrange the link element in a position which does not deviate very far from the vertical to ensure that the pressurised-fluid chamber is at all times full of pressurised fluid. In order to allow the link element to be installed in any position, particularly where space is limited, the pressurised-fluid reservoir is enclosed in a pressurised-fluid reservoir chamber (20) which is preloaded in the direction of a reduction in volume and is separated from the space in the housing (10) containing the helical compression spring (11). <IMAGE>

Title: Air delivery slots aerating water from inflatable body - expand during use to increase self-cleaning action
Inventor: JAEGER ARNOLD
IPC: B01F3/04
Filed: 1989-07-04
Abstract: Air for delivery into a body of water, sewage etc. as a stream of fine bubbles from the slots in an elastomeric wall is fed into the distributor from a pipe  affixed by a clip or other connector to a pipe integral with the slotted wall element. This inflatable element has a thicker or harder rubber structure in its lower wall, acting as support. The upper wall contains the slots which under the internal air pressure open out as the balloon swells. The balloon holds a solid reinforcement ring or a perforated disc with dia. matching that of the uninflated balloon.  In one alternative, the balloon is formed as symmetrically bulging opposite slotted faces of two perpendicular walls affixed to a vertical air feed pipe. ADVANTAGE - Increased mobility of slot walls increases self-cleaning action during use.

Title: Concrete coating test - uses grid scoring for section of coating and clinging foundation to be peeled off with adhesive strip
IPC: G01N3/00
Filed: 1990-01-11
Abstract: To test the coating on a stone and partic. a concrete surface, a brushed surface is cut as a test section and, at the same time, the foundation is scratched to maintain a cutting interval of at least 4mm. An adhesive strip is applied flat to the testing point and then peeled to carry coating and/or foundation material with it. Pref. a gap between the cutting lines of at least 5 mm is maintained and the foundation, during cutting, is scratched to a depth of at least 100 microns and pref. 300 microns. The adhesive strip, together with the clinging coating and any foundation material is secured to a transparent film or plate for evaluation and recording.  The cutting action is applied using a screen rule to give at least four cuts, parallel to each other, and at intervals of at least 4mm. Slits (18) are closed at the ends (20) to allow a cutting  blade to be inserted as in a stencil. The rule is a rigid plate (10) of a non-rusting metal, pref. brass, with a wall thickness of 2-6mm, and carries four to six slits at intervals of at least 5mm with a slit width of 0.5-1.5 mm, pref. about 1.0mm.
