Patent DE-3231371-A1 (DE)
Title: Hydraulic supply device
Inventor: SANDAU HARTMUT
IPC: B60T7/20
Filed: 1982-08-24
Abstract: The invention proposes a hydraulic supply device in which a sleeve (12) is seated in leak-tight fashion in a longitudinal hole (11) of a brake valve housing (10). In the sleeve (12) there is a spool (30), which rests on a pin (34) held by a split pin (49). On an upper collar of the spool (30) there is a packing (38) designed as a non-return valve, the lip (39) of which closes holes (41, 42). If the pin (34) tears off, the packing (38) is displaced to such an extent that it frees the holes (41, 42) and pressure medium stored in the accumulator (47) flows to the brake cylinder (26). The construction according to the invention makes it possible, with just one device, to shut off the inlet opening (18) and open the holes (41, 42) leading to the accumulator (47). The required high pressure is furthermore available in the accumulator (47) at all times during operation and brings about automatic braking of the trailer if the trailer breaks away from the tractor. <IMAGE>

Title: Prefabricated panel element with a mineral-fibre board and building-element kit for a wall cladding with such panel elements
Inventor: SCHMITZ ERNST
IPC: E04B1/84
Filed: 1982-10-06
Abstract: A laminated panel element (1) is prefabricated from a sheet-metal cladding cassette (2) and a mineral-fibre board (3) with a comparatively low specific gravity of, for example, 40 kg/m<3> and is made available in this form. The cladding cassette (2) has in relation to the cross-sectional dimensions of the mineral-fibre board (3), in the direction of both the width (b) and the lateral height (h) of the panel element (1), such an undersize that the mineral-fibre board (3) is put under pressure both in the direction of the width (b) and in the direction of the thickness (lateral height h). The relatively large surfaces bearing against one another thereby result surprisingly in a stiffening effect for the panel element (1) as a whole, which makes it possible to use the panel element (1) virtually in the same way as a rigid solid panel during transport and assembly. In a building-element kit for a wall cladding, therefore, it is necessary to provide only fastening sections with shoulders which hold the panel elements (1) in the region of their open end faces (3a), whilst the panel elements (1) between the fastening sections are self-supporting. This affords a very considerable saving in terms of the outlay for assembly. <IMAGE>

Patent DE-3246625-A1 (DE)
Title: Hollow rivet
Inventor: BRILES FRANKLIN S
IPC: F16B19/10
Filed: 1982-12-16
Abstract: A hollow or blind rivet, which consists of an axial hollow shaft, a conical, annular rivet head for forcible engagement in a countersunk hole in the workpiece, and a mandrel, which can be pulled back from the accessible side of the workpiece, has, in order to improve the long-term strength of the rivetted joint and the clamping forces produced by means of the rivet, a design of the rivet head having an annular end surface, a first region, which tapers conically forwards and is arranged in front of the end surface for forcible engagement with the countersunk hole in the workpiece, and a second region, which tapers conically forwards and is arranged in front of the first conical region, the cone angle of the first conical region being approximately 2 DEG  to 15 DEG , and being essentially smaller than the cone angle of the second conical region. In this case, the rivet head interacts with the workpiece in order to form an anchorage which contributes to maintaining an essentially vertical position of the rivet with respect to the workpiece and to the clamping forces.

Title: Self-aligning piston without piston rings
Inventor: GUENTHER EBERHARD DIPL ING
IPC: F04B37/16
Filed: 1983-09-19
Abstract: The invention relates to self-aligning pistons without piston rings, as used in hermetic coolant compressors, in particular for domestic refrigeration devices. The object of the invention is to achieve an improvement in the efficiency of the hermetic coolant compressor while maintaining the linear contact of the spherical washers, measures being proposed to increase the degree of admission of the hermetic coolant compressor. Patent no. 155856 proposes a self-aligning piston without piston rings, in which a plurality of moveable spherical washers are disposed on the piston rod side of the fixed spherical washer and are retained by a fastening element. As a further development of the invention it is proposed to guide the moveable spherical washers on the piston rod in such a way as to prevent rotation around the piston rod. All the spherical washers are provided with openings or bevels, in order to achieve communication between the cylinder chamber and the suction gas atmosphere of the casing in the initial phase of the suction stroke, preferably from 10 to 60 DEG  after top dead centre. The invention is preferably applicable in the construction of hermetic coolant compressors. Possible further areas of application are compressors and pumps in general, i.e. all motors and machines using piston compression of the medium. <IMAGE>

Title: Device for automatically turning a foresail
Inventor: ROMMEL PETER
IPC: B63H9/10
Filed: 1983-10-15
Abstract: Devices for automatically turning a foresail (15) on sailing yachts and dinghies have for a long time proved successful in simplifying the handling of yachts, even with a smaller crew. Known devices of this type, however, have disadvantages with regard to the optimum trim and the reduction in the effective sail area in increasing wind. To avoid these disadvantages, the invention proposes a self-turning foresail device, the foresail boom (18) of which can be secured in inclination relative to the foresail plane in order to obtain in every sail position an approximately uniform, optimum loading of the leech (34) of the foresail (15) and thus optimum trim of the same. In addition, the device of the invention is especially suitable for simple reefing of the foresail (15). <IMAGE>
