Patent DE-3735170-A1 (DE)
Title: Method of constructing pile foundations
Inventor: GELLERSEN HEINZ
IPC: E02D27/36
Filed: 1987-10-14
Abstract: A method of constructing pile foundations, in particular on landfill sites, is specified, in which protection against ingress of contaminated material into deeper soil layers and towards the surface is obtained by applying a supporting liquid between bore casing and surrounding soil. Contaminated soil material is likewise prevented from being carried forward into deeper soil layers by designing the bore casing (5, 12) with a displacement point. In a further embodiment, the cast-in-situ pile produced in this way can be further secured in the area of the landfill bottom by virtue of the fact that an outer casing (13) sunk along with the bore casing during the driving of the latter is left in the soil after completion of the cast-in-situ pile. The invention prevents contaminated soil from being taken into bearing deeper layers, and no water can penetrate the surface into the clean soil areas. Furthermore, gas or liquids are prevented from being able to escape along the pile. Finally, the pile is protected against harmful attacks from the landfill material.   <IMAGE>

Title: Process for thermally bonding filament or strip ends of synthetic meltable materials
Inventor: PERTERMANN HANS-HOLGER
IPC: H02K15/00
Filed: 1987-11-20
Abstract: Process for thermally bonding filament or strip ends of synthetic meltable materials by means of focused beams of light or heat, for use in packaging technology, when handling thin or filamentary materials and, in particular, in electrical machine construction in the case of dynamo winding overhangs fastened by bandings. These beams of light or heat impinge on the filament or strip ends, aligned by means of an air suction stream, at a material-dependent distance from the basic element, act for a certain time and soften the filament or strip ends, or melt off excess filament or strip material, which is transported away by the air suction stream, and also begin melting the remaining short filament of strip ends, which by the nature of the material contract towards the basic element and form one or more melt beads, which, after curing, effects the permanent bonding of the filament or strip ends, now bearing against the basic element.

Title: Clutch disc with radial elasticity
Inventor: DOTTER KARL-HEINZ DIPL ING
IPC: F16D3/62
Filed: 1988-03-09
Abstract: The invention relates to the arrangement of approximately tangential leaf springs between the hub and the lining carrier of a clutch disc. In this arrangement, the ends of two leaf springs coming from different directions of rotation are riveted to each fastening point on the hub and on the lining carrier by means of one rivet in each case. Deformation of a convex portion of each leaf spring and the axial prestressing of the leaf springs makes it possible, on the one hand, to achieve high radial elasticity and, on the other hand, to maintain the rigidity of the clutch disc in the axial direction.

Patent DE-3822627-A1 (DE)
Title: Inductor, in particular for wideband use
Inventor: ALBERT RICHARD
IPC: H01F17/02
Filed: 1988-07-05
Abstract: Inductors, for example in the form of coils, have, above all, numerous resonances, above the first parallel resonance, which lead to undesired losses. In order to obtain high, low-resistance and extensively resonance-free impedance above the first parallel resonance, the inductor according to the invention has a capacitive and/or inductive electrical coupling between the end and/or the start of the coil winding to a mid-region of the winding. The purpose of this is to shunt out a first imperfect winding part of less than 1/3 relative to the total length of the coil or of the total size of the inductor. The inductor is especially suitable for wideband use. <IMAGE>

Title: Method and device for cutting sheet material
Inventor: TAHARA SYUJI
IPC: B26D1/08
Filed: 1989-01-18
Abstract: A method is disclosed for cutting fed sheet material into a cut-off part and a remaining section by establishing contact between a movable cutting edge and a fixed cutting edge, in the case of which method the remaining section is introduced, after cutting, into an intermediate space between the fixed and the movable cutting edges over a predetermined insertion distance. The end of the remaining section can therefore be prevented from rolling or falling downwards and forwards in the direction of movement of the movable and fixed cutting edges. A device is also disclosed for cutting fed sheet material into a cut-off part and a remaining section by establishing contact between a movable cutting edge and a fixed cutting edge, in the case of which device a plate element contained within the latter prevents movement of the end of the remaining section together with the movable cutting edge after cutting. This makes it possible to prevent upward rotation of the end of the remaining section by the movable cutting edge.

Title: Auxiliary air feed for IC engine - has underpressure control valve with return shock safety sprung valve
Inventor: BLUME AXEL
IPC: F02D31/00
Filed: 1989-11-09
Abstract: The supply feeds auxiliary air into the intake channel of an IC engine, downstream of the throttle. It has a Venturi nozzle in the channel, a feed tube into the nozzle and a control in the feed tube. It has an underpressure tube, extended from the intake channel into a control chamber of the control. The underpressure tube controls an underpressure control valve (16) with a return shock safety sprung valve. This reduces the underpressure supplied to the control chamber of the control (13) by addition of air, and the underpressure tube profile may be shut-off, when there is a corresponding underpressure drop in the intake channel (1). ADVANTAGE - Exhaust gas pollution is reduced.
