Title: Pull-out mechanism with running rollers for furniture parts which can be pulled out
Inventor: FULTERER MANFRED
IPC: A47B88/04
Filed: 1981-03-10
Abstract: In the case of pull-out mechanisms with running rollers for furniture parts which can be pulled out and have at least two profiled rails (2, 3), in each case disc-like adjustment bodies (1) are provided on the fixed profiled rail (2) in the front region of the latter, can be rotated about their axis and can be used to compensate for and/or set the play of the profiled rails (2, 3) in the horizontal direction. Along its edge, the disc-like body (1) has, over a sector of about 90 DEG , a contact surface (10) which rises like a screw surface with respect to its base surface in the axial direction of the adjustment body (1). The diameter (D) of the adjustment body (1) is larger in the region of this contact surface (10) than the diameter of the running rollers of the profiled rails (2 and 3). The edge of the horizontal flange (18) of one profiled rail (3) rests against this contact surface (10). This arrangement and design of the adjustment body (1) makes it possible to adjust the latter even when the displaceable piece of furniture is fastened, which permits adjustment in a simple and, furthermore, accurate manner. <IMAGE>
Patent DE-3110935-A1 (DE)
Title: Mosaic pressure plate
Inventor: DANSSMANN JUERGEN ING GRAD
IPC: G01N3/04
Filed: 1981-03-20
Abstract: When testing machines with rigid pressure plates are used, the true uniaxial compressive strength of a material can be obtained in mineral building materials only on slender specimens (prisms or cylinders). In the case of compact specimens, the influence of friction on the pressure surfaces falsifies the material data found. The force introduction systems of a steel brush and slack pressure plate, which allow a largely unforced introduction of force, are already being used in the research field. Owing to their structure, these systems can be used only with limitations. For the general testing field, it is possible to use the mosaic pressure plate. This invention comprises a system of small pressure plates which are mounted by means of roller bearings to be displaceable in the plane. As compared with the known systems, this pressure plate system widens the range of application to specimens of any desired shape and allows the true compressive strength to be determined even on compact, flat test specimens.

Title: Refrigerating plant for the air-conditioning of mining operations
Inventor: TUTTASS EDMOND
IPC: F25B1/06
Filed: 1981-03-28
Abstract: A refrigerating plant for the air-conditioning, in particular of underground mining operations, has two circuits, the above-ground primary circuit supplying the underground secondary circuit in each case with the necessary cold or cool bottom. The refrigerating machine arranged above ground has a refrigerant main circuit and a refrigerant sub-circuit which are guided together for example in an injector nozzle. The refrigerant circuit is evaporated in advance in an evaporator under high pressure and then supplied to the refrigerant main circuit. Via this injector nozzle, the gaseous refrigerant entering the condenser is given sufficiently high pressure in order then subsequently to be capable of being condensed. It is then possible to forego electrical energy conversion because the high evaporation pressure of the refrigerant circuit originates for example from mine gas combustion, i.e. operation-internal energy extraction. <IMAGE>

Title: Hydraulic flow-regulating valve, e.g. for controlling cold-water coolers in underground mining
Inventor: HEBBEN ROLF
IPC: F16K3/26
Filed: 1981-05-15
Abstract: The invention relates to a hydraulic flow-regulating valve according to Fig. 1, e.g. for controlling cold-water coolers in underground mining, in which a flow of medium, e.g. the cold-water inflow, passes axially through a valve cylinder in which a piston slide provided with a choke is guided. At the piston skirt, the piston slide has a multiplicity of radial bores as a fluidic connection to an annular space defined by the cylinder and at least partly by an inner sleeve. Radial bores of the inner sleeve lead into the annular space. In this arrangement, the piston slide preloaded against the direction of flow with a spring sitting on the inner sleeve controls radial bores of the sleeve with its piston skirt, and, with the aim of eliminating greater losses of the medium in the event of leakages from the hydraulic circuit protected by the flow-regulating valve, provision is made for the seat (20) of the spring (19) to be arranged in an axially movable manner on an arm of a hydraulic pressure balance (22-23), the other arm of which is loaded with another flow of medium, and for the deflection of the balance (22-23) to enable the piston skirt (10) to run over the sleeve bores (15, 16). <IMAGE>
