Patent DE-3438219-A1 (DE)
Title: Two stroke diesel engine with opposed free pistons
Inventor: WAGNER ALBERT
IPC: F02B3/06
Filed: 1984-10-18
Abstract: In the two-stroke diesel engine with opposed free pistons and hydraulic pump, the reciprocating movement of the free pistons, with complete balancing of masses in each cylinder, is converted into rotary movement by the hydraulic oil delivered by the hydraulic pump or pressurised water using a hydraulic motor or a counter pressure free jet turbine. According to the invention, in the case of two cylinders one of the buffer chambers of the opposed free pistons, which chambers are arranged in the cylinders, is connected to a starting injection pump, so that for a starting pressure of 5 bars following injection in this cylinder the injection gap is uniform due to the later injection into the other cylinder at a buffer pressure of 10 bars. In addition, a buffer chamber of each cylinder is connected to the injection pump of the other cylinder, so that injection can occur due to the compression force only when the buffer pressure is falling, any change of the injection gap being limited and compensated for by the injection delayed by the high buffer pressure. In addition, the pressure and intake valves of the hydraulic pump have an expanded, nozzle-shaped gap outlet and a constricted, nozzle shaped gap inlet with a wide, spherical valve seat, so that the pressure losses are low at high piston speeds.

Title: Protective covering for parts on machines
IPC: B23Q11/08
Filed: 1984-11-03
Abstract: A protective covering for parts on machines has a foldable support (3), which is provided on the outside with a slatted covering which is formed by slats (1) overlapping one another in an imbricated manner. The slats (1) are in each case fastened by means of bands (2) on the foldable support (3). For the bands (2), preferably textile bands are provided. The bands (2) are in each case fastened on the one hand on a slat (1) and on the other hand on a fold wall (30) of the support (3) and have a slack intermediate section (22) between the end section (23) on the support side and the end section (21) on the slat side. As a result, the outer slat (1) of adjacent, overlapping slats (1) in each case rests fully or partially on the inner slat (1) under the effect of gravity. This measure serves for creating a protective covering which, while providing constantly reliable screening of the upper side of the support (3) by the slatted covering, is of a simple design and can be pushed together to be as small as possible (Figure 1). <IMAGE>

Title: Play-free mounting for axles or shafts in the axial direction
Inventor: KIELING REINER
IPC: F16B21/16
Filed: 1984-12-19
Abstract: In order to mount axles or shafts or bearing parts with axles without play in the axial direction, resilient retaining and/or compensating washers are required. These are used, on the one hand, to compensate for manufacturing tolerances and, on the other hand, to eliminate any possible sources of troublesome noise. The object on which the invention is based is to provide a play-free mounting for axles or shafts or other bearing parts with bearing axles which is simple to produce and can be assembled without auxiliary tools. This object is achieved, using a washer which can be snapped resiliently into a snap-in groove of an axle, by virtue of the fact that the central opening (15) in the washer (14) is in the form of an elongate slot and that the slot-like central opening (15) can be expanded in the form of a circle to allow it to be fitted over a shoulder (16) of the axle (4) and can return to the slot shape after the flexible washer (14) has snapped into the snap-in groove (17). The washer (14) serving as the retaining and compensating washer is thus connected in a captive manner to the axle (4). <IMAGE>

Title: Rubbed-off material conveyor with rake
Inventor: PFEIFFER HEINZ-DIETER
IPC: B65G25/02
Filed: 1985-04-12
Abstract: A rubbed-off material conveyor which is of simple construction and requires little maintenance has, besides the rigidly arranged collecting trough, a rake which can be displaced via a working cylinder. The said rake is formed by the longitudinally extending rectangular tubes and the carriers which are arranged at right angles to the latter. The said rake is connected to erecting levers in such a way that it is guided tightly over the floor of the collecting trough during the forward stroke and at an appropriately large distance during the return stroke. This ensures that the rubbed-off material which is collected by the collecting trough is in each case pushed in the discharging direction during the forward stroke, while the rake is guided past the heaped up rubbed-off material during the return stroke, in order once again to push the rubbed-off material a bit further during the next stroke. As clamping friction is completely avoided, a favourable level of efficiency is achieved, an extension can be easily achieved thanks to the small number of moving parts and it is possible to set the spacing of the rake in such a way that a short-stroke cylinder can be used in each case. <IMAGE>

Patent DE-3524699-A1 (DE)
Title: Temperature regulator
Inventor: EBERL KARLHEINZ
IPC: H01H89/04
Filed: 1985-07-11
Abstract: A temperature regulator 10 consists essentially of a bimetallic element 14 (which is mounted on a retaining base 12 and is constructed in the form of a plate) and of two snap-action switches 18, 20 which are operated by the pivoting end 16 of the bimetallic element 14. One of the snap-action switches 18 is used for switching on and off a first, and the second 20 for switching on and off a second, heating, cooling or ventilator stage. The temperature values for the snap-action switches 18, 20 to switch on and off can be adjusted via an adjusting device 22. In order to design such a temperature regulator in such a manner that, in a structurally simple manner, the temperature can be raised (or lowered) by manual operation from a level above the switching-on point of the second switching contact, it being intended to ensure that the temperature does not end up beyond the setting range which is regulated by the first snap-action switch, a manual operating device 40 is provided for switching the second snap-action switch 20 on at a temperature which is higher (lower) than the switching-on temperature of the second snap-action switch. The operating device 40 displaces the bimetallic element into its switching-on bending position in the region of its intrinsic movement hysteresis. <IMAGE>
