Patent DE-3516050-A1 (DE)
Title: Vibration plate
IPC: E01C19/23
Filed: 1985-05-04
Abstract: The invention relates to a vibration plate, the bottom plate of which, which carries out the ground compaction, can be set in vibration directly by a motor-driven vibration exciter mounted on it and is weight-loaded by an upper weight which is sprung in relation to it. In the known vibration plates of this type, the vibration exciter also carries out the forward movement of the plate. In the case of cohesive ground, it can in this case occur that the vibration force with advance component generated by the vibration exciter does not manage to free the plate from the ground at the same time and move it further in the desired direction of travel so that the plate remains adhering to the ground. This disadvantage is eliminated according to the invention by at least one continuous belt 8 which extends approximately parallel to the vertical longitudinal central plane (L) of the plate with the upper strand above the bottom plate 1 and with the lower strand below it and is guided in its longitudinal direction movably on the vibration plate via deflection devices 5a and 6a, the belt region extending over a substantial part of the width of the bottom plate. In the region supported by the belt or the belts 1, the bottom plate 1 can at any time be freed easily from its support, under the vibration forces, irrespective of the nature of the ground, the prerequisite for the problem-free forward movement of the vibration plate in the direction of travel thus being guaranteed under all operating conditions. <IMAGE>

Patent DE-3537337-A1 (DE)
Title: Clamping device
Inventor: STAHL BERNHARD
IPC: B23Q3/06
Filed: 1985-10-19
Abstract: In order to carry out clamping in particular independently of the effects of viscosity, temperature, applied pressure, leakages and pipe and hose extensions occurring during the use of air or oil as pressure medium, in a clamping device consisting of a compensating unit which is combined with a clamping head for adjusting a tie rod, is acted upon hydraulically or pneumatically and has housing parts which can be axially removed from one another, a clamping head can be designed as an exclusively hydraulically or pneumatically operated cylinder which is coupled hydraulically or pneumatically to the compensating unit and is supported with the cylinder housing on an outer housing of the compensating unit. In its clamping position pulling the tie rod against the material to be clamped, the cylinder is mechanically supported by the axially adjustable housing parts of the compensating unit, in the course of which the pressure in the cylinder is fully removed but the clamping force is maintained.
Patent DE-3543835-A1 (DE)
Title: Mounting arrangement for a power unit assembly
Inventor: BATHELT HARTMUT DIPL ING DR
IPC: B60K5/12
Filed: 1985-12-12
Abstract: In a mounting for a power unit assembly in the chassis of a motor vehicle the assembly is supported on each side by way of an engine mounting 5 and a transmission mounting 6 on the chassis (body supports 8 and 10). The arrangement is so designed that in the event of vertical movements of the power unit assembly the one bearing, for example 5, is subject to compressive loading and the other bearing, for example 6, to tensile loading and vice versa. In the case of tilting movements about the transverse axis, however, both bearings 5, 6 are subject to compressive or tensile loading. The bearings 5, 6 are designed as hydraulic bearings, the pressure chambers 14 and 14a of which are connected to one another by a line 15 with the restriction 16. In the case of vertical movements of the power unit assembly the pressure chamber of the bearing subject to tensile loading acts as receiving volume for the pressure chamber of the bearing subject to compressive loading, so that the rigidity of the bearing is essentially determined only by the elasticity of the elastic peripheral wall 13 serving as bearing spring. In the case of tilting movements of the power unit assembly about the transverse axis both bearings 5, 6 are simultaneously subject to compressive or tensile loading. For this reason no volume compensation can occur by way of the connecting line 16, so that high rigidity and damping of these tilting movements in the low frequency range are obtained. <IMAGE>
Patent DE-3544921-A1 (DE)
Title: Disc cooler, in particular oil cooler
Inventor: ZINSSER WERNER
IPC: F28D9/00
Filed: 1985-12-19
Abstract: In a disc cooler, a plurality of disc members are stacked one upon another in the shape of a packet and separated from one another by spacers. Oil to be cooled flows in the disc members, while the cooling medium flows in the gaps, formed by the spacers, between the disc members. The disc members are soldered to the spacers with the aid of a soldering foil, which is introduced between the individual disc members during production. In order to hold the individual spacers, lugs or flapping pieces are cut out of the soldering foil and are bent away over the spacers. The soldering foil holds the spacers in this case in such a way that soldering material is located on both sides of the spacers. Use is made as spacers of, inter alia, rings which are arranged coaxially on one another between individual disc members, and thereby form the inlet and the outlet of oil to and from the individual disc members. For the purpose of positioning the disc members, there are provided thereon, on recesses corresponding to the spacing rings, collars which engage in the rings. All the spacers have the same height, which fixes the spacing of the disc members, and are arranged between the disc members in accordance with the desired stability of the disc bundle.

Patent DE-3603152-A1 (DE)
Title: Base for luminaires
Inventor: ILLGUTH GUSTAV
IPC: F21V21/06
Filed: 1986-02-01
Abstract: This base for luminaires is suitable as an auxiliary unit for fully employing the illuminating power of table lamps of old and modern design. Particularly in the case of reading wide written works such as, e.g. opened-out illustrated magazines, it is found that the illuminating power of a table lamp frequently does not reach as far as the outermost edge of the more distant half of the magazine. Moving closer to the light source, particularly in the case of bulky illustrated magazines, often fails because the luminaire blocks the space. The invention provides a cavity (a hood) which is capable of accommodating wide written works or parts thereof and/or of further guiding them unfolded into an underpass (hood) - running frontally under the obstacle of the luminaire - so that in this way it is possible during reading for parts of a printed work which are remote from the light source to be pushed nearer to the light source. Possibilities for combination     a) with the most varied models of table lamps,   b) with tea lamps or other suitable household goods,   c) with writing tables - connected permanently or detachably, d) as a cassette (advertising gift article for readership or publishing houses).
