Title: Process for repairing a buried pipeline
Inventor: MUELLER HANS
IPC: E03F3/06
Filed: 1988-01-20
Abstract: By using a calibrating (sizing) hose which adapts to the contours and the progression of the pipeline as well as synthetic resins which can harden, the intention is to develop a cost-effective and simple process which is suitable particularly for repairing parts of pipes. The resin is pumped, via a feedline, into a supply chamber, which is formed by sealing elements (16, 19, 20), the front end of an inverted calibrating hose (13) and the inner surfaces, located therebetween, of the pipe wall (10). The quantity of resin is moved further through the inverted calibrating hose, the synthetic resin being pressed into cracks or ducts (15), with the formation of an inner coating. The sealing elements are also moved at the same rate and in the same direction. The process according to the invention is conceived particularly for repairing sewer ducts. <IMAGE>

Patent DE-3806422-A1 (DE)
Title: Lock with motor and locking-bit drive
Inventor: BACH BJOERN
IPC: E05B47/06
Filed: 1988-02-29
Abstract: Lock with a bolt which can be drawn back into the open position by motor or locking-bit drive and moved into the closed position by spring force, and a catch for securing the bolt in the open position which can be released by means of an auxiliary latch. To avoid the risk that the lock, after manual opening of the bolt without opening the door, remains, unrecognised, in the open position, it is envisaged that the catch is ready for engagement only when the auxiliary latch is extended. The travel of the locking-bit in the opening direction is expediently limited in the open position of the bolt inside its bolt engagement.

Title: Circuit arrangements for an electrical ventilation reversing valve
Inventor: MEYER OTTO
IPC: F02M5/08
Filed: 1988-05-02
Abstract: In order to solve heating problems, known circuits switch the float chamber ventilation, for example as a function of the fuel feed pressure or of internal and external ventilation. These designs are unsatisfactory, however, since they do not solve the heat problem occurring whilst the engine is in operation The new circuit arrangement is characterised in that, in the event of higher temperatures in the float chamber area, it switches to external ventilation for a certain period of time. Circuit arrangements of the said type have applications in motor vehicle construction. <IMAGE>

Title: Method for the coding of television signals
Inventor: DIRR JOSEF DIPL ING
IPC: H04N11/00
Filed: 1988-07-22
Abstract: In the case of the known methods for the coding of television signals, particularly in the case of digital coding, a large bandwidth and a large outlay are required. In the case of the invention, the bandwidth is considerably reduced by means of doubled QAM and/or by means of code-multiplex coding and/or by means of a combination of amplitude and phase coding. The phase coding is in this case obtained with the aid of rectangular waveform pulses which are produced by means of counting elements which are controlled at a raised frequency. Sinusoidal alternating currents are formed from the rectangular waveform pulses, by means of a low-pass filter. The phase changes are then obtained by changing the period durations.

Patent DE-3828069-A1 (DE)
Title: Self-sensing clamping device
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: B60R22/185
Filed: 1988-08-18
Abstract: A clamping device is described for locking belts of vehicle safety belt systems in accidents. A clamping wedge (3) with a toothed clamping surface (5) is mounted on two sensor balls (10) which are situated alongside one another and is guided by the latter in the event of an accident, with the support of a sensor weight (11) towards the belt (18). A special design of the clamping tooth results in a virtually slip free carrying effect and finally a wedge-type clamping action. The geometric design together with the frictional conditions guarantee automatic unblocking. The specially selected frictional conditions together with low-friction sliding coatings also result in a clamping action which is gentle to the belt and a high degree of loadability. The clamping device is of simple construction and is composed of a small number of parts, which means that it is cost effective, light in weight and does not occupy much space. The self sensing clamping principle can also be applied in a deflection clamper if two identical clamping wedges (3') are arranged one above the other and with the inclined sliding surfaces (4') running towards one another in a clamping casing (2'). <IMAGE>
Patent DE-3833558-A1 (DE)
Title: Radial piston pump
Inventor: LISKA GEORG
IPC: F04B1/053
Filed: 1988-10-03
Abstract: In a radial piston pump, pistons (10) deliver oil to pressure channels (21) via a so-called flat spiral spring valve (20). The pressure channels (21) lead to a common annular channel (25) which is created e.g. by a countersink (27) of a housing bore (7) and a radial wall (5) of a collecting space (4). The annular channel (25) is connected to the collecting space (4) via a discharge channel (26). The oil which is delivered flows in a circular-path flow through the annular channel (25) and is then deflected through the discharge channel (26) into the collecting space (4). This results in a reduction in the design-related pressure pulsations in piston pumps and consequently also in less pump-running noise. <IMAGE>

Title: Damping element and apparatus which is damped by said damping element
Inventor: BLASS BERNARDO DIPL ING
IPC: F16F1/371
Filed: 1988-10-13
Abstract: The damping element is designed as a flexible lug (1). Said lug (1) exhibits an insert (8), which extends between two fastening points (2, 3) and consists of a tension-resistant material, such as steel wire or glass fibres, as well as a matrix (9) which encloses the insert (8) and consists of a material having a small modulus of elasticity, such as lead. Such a damping element effects rapid attenuation of the movement of an apparatus which is subjected to impact, in particular earthquakes, if it is fastened, on the one hand, on the apparatus and, on the other hand, on a fixed bearing point or a moveable, inert mass, in doing so forming a bending force. <IMAGE>
Patent DE-3839024-A1 (DE)
Inventor: KORTHAEUER HELMUT DIPL ING
IPC: F04D7/04
Filed: 1988-11-18
Abstract: Centrifugal pump for pumping molten masses, especially molten explosives. Molten explosives having a high content of infusible solid explosive are gravimetrically pumped due to the associated dangers. This makes high buildings and protective surrounding walls necessary, with the disadvantage of considerable effort and high costs as well as relatively poor accessibility to the installations. The object of the invention is to avoid these disadvantages and to permit the pumping of molten explosives to be carried out on just a few levels, if not just a single level, in easily accessible and uncomplicated installations. The vertically arranged pump shaft of a centrifugal pump bears at its lower end an unchokeable impeller with upwardly open blades, with which the pump housing forms an annular gap and, at the end, a free space which is connected by means of bores directed obliquely outwards from bottom to top to the pumping space located above the impeller and fed with pumping medium from above. Pumping of molten masses, in particular having a high solids content, and in particular molten explosives having a high content of infusible high-energy solid explosive.
