Title: Method for constructing sheet piling in ground with obstructions - uses bore holes, sunk below desired final depth, to create erosion zones between obstacles and final depth
Inventor: PIELSTICKER ALBERT DIPL ING
IPC: E02D7/26
Filed: 1992-10-13
Abstract: A row of bore holes (8) are sunk to below the desired final depth (9) of the sheet piling. Overlapping areas of erosion (16) are created in at least the area between the obstructions (7) and the final depth, by using a nozzle jet process and a cutting medium. This permits the obstacles to sink below the desired depth. Sheet piles, combined tube/sheet elements, or posts carrying sheet piles, are finally lowered to desired depth, using vibrators or impact tools. The areas of erosion extend from below the final depth to above the obstacle layer. USE/ADVANTAGE - Large depths, e.g, construction of quays. Secure construction at lower costs.

Title: Arrangement for detecting and displaying vehicle braking processes - contains speed transducer and evaluation circuit contg. pulse counter and comparator.
Inventor: FLECHSIG MAX
IPC: G01P15/16
Filed: 1992-10-28
Abstract: The arrangement includes a speed transducer, a pulse counter, a memory for successive and cyclic receipt of the counter contents, and a comparator for comparison of the counter contents with the memory contents. The speed transducer (IG) output drives a pulse-shaper (MV) with its direct output (Q) feeding the interrogation input of the pulse counter (Z), via a delay stage (VZ1).  The inverse pulse shaper output (Qbar) drives the pulse counter's count input via a gate (T) also fed by a clock generator. The parallel outputs of the pulse counter (Z) and the memory (SP) feed a comparator (K) triggered by the direct pulse-shaper output (Q). USE/ADVANTAGE - For detecting and indicating speed changes esp. during vehicle braking. High resolution and close speed tracking are achieved.

Title: Blown plastic film tubing prodn. appts. - has turning rods system with reflector points between lay-flat device and reeling station, diverting rollers with axially moving guides, etc.
Inventor: HESSENBRUCH ROLF
IPC: B29C48/10
Filed: 1993-04-02
Abstract: Appts. has turning rods system with several deflector points, located between the lay-flat device and the reeling station. One deflector point has a stationary rod and/or a rotating roller to divert the oblique laid-flat film tubing. The diverting rollers used have guides parallel to their axes and the guides can move axially through the laid-flat tubing and be moved back to their starting position by devices at the end not enveloped by the tubing. A one diverting/guide point one turning rod or roller is replaced by a number of parallel rods or rollers which break up the total wrap-round of the film. In the lay-flat and traction area of a blown film machine film tubing flattened by rollers passes a parallel, but sideways displaced, guide roller to prevent escape of air from inside the tubing. The film then passes to a 1st deflector guide of two rollers where it is turned through 180 deg. in one plane. The rollers are each set at 45 deg., pref. 90 deg. The tubing next passes to a guide roller and a 2nd similar to turn the film through 180 deg., Again the film now meets turning guides set at 45 deg., to produce a similar direction change as before. ADVANTAGE - The layer out eliminates the substantial displacements which tend to arise in the guides.

Title: Apparatus and method for mounting and dismounting bridges, in particular temporary bridges, in existing railway tracks
Inventor: SCHMIDT FRITZ J
IPC: E01D15/127
Filed: 1993-09-30
Abstract: An apparatus for mounting and/or dismounting bridges, in particular temporary bridges, in existing railway tracks is to be provided, being simple in terms of construction and handling. In particular, this apparatus, which can be referred to as a temporary bridge-mounting machine, is to be usable without obstructing existing neighbouring tracks. The mounting or dismounting of a temporary bridge is to be possible with this apparatus in an extremely short time in order to limit the necessary interruption of traffic on the track in question to a few hours. For this purpose, said apparatus is a portal crane (gantry crane) which can be transported on at least one railway transport waggon and has supports, capable of being extended vertically alongside the track, for direct support, enabling the apparatus to rest on the at least one transport waggon, on the track subgrade. By means of such a portal crane, an extremely efficient working process is achievable, requiring few auxiliary operations, additional equipment and transporting means. This makes possible, inter alia, a high frequency of use. Overall, very low costs per construction site thus result.
