Patent DE-3401489-A1 (DE)
Title: Method of driving underground cavities by compressed-air operation
IPC: E21D9/00
Filed: 1984-01-18
Abstract: During the driving of a tunnel (4) in water-saturated soil by compressed-air operation, the compressed air penetrates into the soil in the area of the heading face (6) in the direction of arrows (10) and forms an air bubble (12) there, the boundary line (13) of which supports the heading face towards the water-saturated soil. From both the area above the heading face (6) and the area of the roof (15), the compressed air which has penetrated from the pressure space (21) into the soil is drawn off from the area surrounding the driving cross-section directly into an area of lower air pressure. For this purpose, filters (14 or 14') are provided in the area of the roof (15) between the tunnel lining (5) and the excavated cross-section. The filters (14 or 14') are attached to a collecting line (17) which leads into the area of atmospheric air pressure. <IMAGE>

Title: Device for developing photographic prints by the colour diffusion method
Inventor: BERNHARDT RAINER DIPL ING
IPC: G03D13/04
Filed: 1984-02-28
Abstract: In a device for developing photographic prints by the colour diffusion method, a solution container is used to store the alkaline working solution and a developing tank is used to store the single-sheet material to be developed. The solution container and the developing tank are connected to one another to form a unit with their openings facing one another. For inexpensive production of the device, it is proposed to select a pair of drums from a conventional developing device, which pair of drums have, at their drum opening, coupling halves which are of the same type as one another, while the drum lids are provided with countercoupling halves which are complementary thereto. Instead of the conventional drum lids, tubular attachments are used which themselves have countercoupling halves at one tube end, but carry connection halves at the other end which can be inserted one into the other to provide a seal. The interconnected attachment pair forms a pouring transfer piece for the working solution in the unit.
Patent DE-3408013-A1 (DE)
Title: Emergency brake device for indirectly acting compressed-air brakes of rail vehicle trains
Inventor: HUBER JOHANN
IPC: B60T17/20
Filed: 1984-03-05
Abstract: The emergency brake device has vent devices (18) for the main air line (1), which devices can be actuated by emergency brake handles (20) and switch back automatically after a specific time period, the aeration taking place in a restricted manner via a nozzle (24). A flow monitoring device (3) is provided at the compressed-air supply device for the main air line (1), which flow monitoring device actuates a display device (12) when the injection of compressed air is at an abnormally high level and, for this purpose, actuates a rapid-braking valve (10) delayed via a timing element (13, 14). The automatic actuation of the rapid-braking valve (10) can be inhibited by the driver of the locomotive by actuating an aeration valve (17) when desired. On being actuated, the vent device (18) brings about, at most, a small drop in pressure in the main air line (1), which serves as a signal and brings about a triggering of the flow monitoring device (3). By actuating the aeration valve (17), the locomotive driver can inhibit the automatic implementation of rapid braking, despite the fact that the vent device (18) is actuated, while travelling through route sections which are unsuitable for the train to stop in; the train can then be brought to a standstill on a suitable section of the route. <IMAGE>

Patent DE-3429755-A1 (DE)
Title: Universally usable safety nutcracker which does not harm the kernels
Inventor: GRETZKE GUENTER
IPC: A47J43/26
Filed: 1984-08-13
Abstract: A nutcracker is described which is automatically set to the diameter of the nut when the operating lever is actuated, cracks the nut without harming the kernel and rules out any risk of injury, even in the case of improper use. These characteristics are achieved by dividing the overall stroke into a setting stroke and the operating stroke. The maximum setting stroke can be 24 mm. The changeover from the setting stroke to the operating stroke takes place automatically at that moment at which the operating lever (3) touches the nut, that is to say when a force occurs at F7. The operating stroke is restricted to 9 mm between the ram (4) and the main part (2). As a result, the maximum operating stroke on the nut is 2.9 mm. Even extreme types of nuts can be cracked without damaging the kernel. By restricting the operating lever (3) at the operating point to a maximum of 2.9 mm, if fingers or thumbs are inadvertently held in the nutcracker, they may be squeezed but will not be injured. Furthermore, all parts, openings and slots are designed in such a way that there are no pinching points. <IMAGE>

Title: Hydraulic control device
Inventor: SCHWERIN GUENTHER
IPC: F15B13/01
Filed: 1984-08-24
Abstract: In a hydraulic control device (10) for a lifting gear control on an agricultural vehicle a control slide valve (37) is designed with negative control overlap between a working chamber (42), a control chamber (43) and a return chamber (44) of a control valve (14). The control chamber (43) is arranged between the working chamber (42) and the return chamber (44) and connected by way of a control line (52) with a restrictor (53) to the return chamber (44). From this control line (52) upstream of the restrictor (53) a line (54) branches off to the pressure chamber (55) of an impact piston (17) of a check valve (16). As a result a relatively low neutral circulation pressure with the control slide valve (37) in the neutral position is possible, which is independent of and also lower than the opening pressure for the impact piston (17) in the lowering position. The pressure chamber (55) of the impact piston is relieved in the neutral and lifting positions of the control slide valve (37). <IMAGE>
Patent DE-3431526-A1 (DE)
Title: Support device for vehicles
Inventor: KREMER ERWIN ING GRAD
IPC: B66C23/78
Filed: 1984-08-28
Abstract: The subject of the application is a support device for vehicles with salient extension arms for increasing the support base, comprising a vertically adjustable support arm on which a ground plate which adjusts automatically to the inclination of the supporting surface is arranged via a ball and a ball socket as connecting elements. Such a support device is to be improved in that, on the one hand, when loaded the movability of the ground plate or of the support plate is not adversely affected in the lowered arrangement of the support arm and, on the other hand, mechanical locking of the ground plate with respect to the support arm occurs when the support arm is raised. This is achieved in that the ball socket has on its inner end a dome-like receptacle for the ball arranged on a radial neck and merges, from the edge of this receptacle in the axial direction, into an area whose diameter is larger than that of the ball or of the ball neck at a respectively radially oppositely located point and merges in the end region of the ball socket with a support face which tapers and is approximately in the shape of a hollow cone. Located opposite the support face is a conical counter-face on the neck, the largest outer diameter of which is larger than the smallest inner diameter of the seat face on the outer end of the ball socket.
