Title: Device for removing deposits from overhead gravity pipes
Inventor: STEINWELLER GERT DIPL ING
IPC: E03F9/00
Filed: 1982-08-30
Abstract: Deposits which have accumulated in overhead gravity pipes with a nominal width of up to 400 mm can be removed by means of commercially available high-pressure flushing devices and vacuum suction devices and also by appropriate clearing carriages. In large pipes with nominal widths of 600 mm upwards, such known cleaning methods are uneconomical. This drawback is to be overcome by the present invention. The clinging deposits are detached with the aid of a high-pressure flushing nozzle which is fixed in a scraper container and to which a corresponding pressure hose of a suitable high-pressure flushing unit is fixed. These detached solids pass through screen bars into the suction chamber which is arranged immediately behind them and to which a suction hose of a vacuum suction unit is connected. The interaction of high-pressure flushing nozzle and vacuum suction brings about targeted removal of solid deposits. The compactness of this device makes it possible to insert it as quickly as possible into the sections concerned. The device is conveyed in the overhead gravity pipe by the pull of a rope.

Title: Machine for mining and tunnelling
Inventor: VURAL GUELERTAN DIPL ING
IPC: E21D9/10
Filed: 1982-12-13
Abstract: In this machine, a support spindle (14) with a roller drilling head is mounted on a boom arm in such a way that it can be driven in a rotatable manner. Cylinder bores in which pistons (15, 16) are loaded hydraulically are provided at the front end of the support spindle (14). The pistons (15, 16) are connected via guide pieces to guide rods (17, 18) which serve as anti-rotation locking means and are guided in bores in the support spindle. The pistons (15, 16) are connected to hollow bodies (38, 39), on the outer circumference of which bearing elements (40, 41, 42, 43) are provided for the rotatable mounting of tool casings (46, 47). Fastened to the tool casings are tool rings (53 to 56, 57 to 60) which are formed with cutting edges at their largest periphery. The tool casings are connected to one another via an elastic ring element (105) and to a flange (103) via an elastic ring element (104), as a result of which it is possible to rotate as a unit the cutting rings formed from tool casings and tool rings. The direction of oscillation of the linear exciters formed from pistons and cylinders can be changed by turning the support spindle. <IMAGE>

Title: Device for warning of a vehicle travelling in the wrong direction in any oneway system, for passenger cars, lorries, motorcycles
Inventor: DELECATE HEIKO
IPC: G08G1/09
Filed: 1983-02-18
Abstract: For the prevention of disoriented drivers driving the wrong way on the motorway or driving into streets in a direction which is not permitted. Warning signals are generated by a buzzing tone and flashing light on the dashboard with simultaneous switching on of the hazard indicator system of the vehicle. After driving 5 or 6 m incorrectly into the motorway exit, three current-conducting contact thresholds which are arranged parallel to one another and are at different distances from one another (3.2) are present. As a result, a distinction is made on the dashboard between leaving an exit correctly, and at the same time no warning being issued, and entering a motorway incorrectly, and at the same time a warning being given. This distinction is brought about by the "time pulse switch" (11/32) which decides, after the respective third touch contact has been triggered, whether or not a warning is to be issued to the driver driving in the wrong direction. If the pulse times or pulse routes passed through are "long-short", the driver driving the wrong way is warned. The necessary contact thresholds are located in a raised position on the carriageway surface and embedded in bitumen so that the required two sliding contacts attached to a mudflap cannot activate the warning signals when passing through puddles. Therefore, there is a safety distance between the lower edge of the sliding contact and the surface of the carriageway of approximately 8 cm. After the warning occurs, the warning signals automatically switch off again. The hazard indicator system has to be subsequently switched off again manually. The device for warning against driving the wrong way into a motorway exit is ... Original abstract incomplete. <IMAGE>

Patent DE-3312990-A1 (DE)
Title: Boring tool
Inventor: WENDEL HEINZ
IPC: B23B29/034
Filed: 1983-04-12
Abstract: In the boring tool, an interchangeable cutting body is fastened to a holder. At the head of a basic body consisting of a head and a locating shank, the interchangeable cutting body can be set to various boring diameters by the holder being rotatably mounted on a journal protruding from the head, with an axis parallel to the axis of the locating shank, at the end face remote from the locating shank, and by catches being provided which follow one another between the head and the holder on a circle concentric to the axis of the journal. A cylinder pin protruding from a radial nose of the head projects in a sliding fit in each case into one of the catches formed as blind bores parallel axially to the axis of the journal so that, in such a way as to save tool costs, improvements result with regard to simple and rapid changing of the boring diameter and fine boring to closer tolerances with higher machining capacity. As a result of unequal catch spacings which are made possible, uniform adjusting steps in the variation of the boring diameter can be achieved.
